所有前述相關申請的全部內容均通過引用合併于本文中。 The entire contents of all of the aforementioned related applications are incorporated herein by reference.
本公開涉及連續板(例如，牆板)製造過程，並且更特別地涉及用於含水燒石膏漿料的分佈的裝置、系統和方法。 The present disclosure relates to continuous sheet (eg, wallboard) manufacturing processes, and more particularly to apparatus, systems, and methods for the distribution of aqueous calcined gypsum slurry.
通過將燒石膏(通常稱為“灰泥”)均勻地擴散到水中以形成含水燒石膏漿料來製作石膏板是習知的。典型 地，通過將灰泥和水以及其他添加劑置於混合器中以連續的方式製作含水燒石膏漿料，混合器包含用於將內含物攪拌以形成均勻的石膏漿料的裝置。漿料被連續地朝向混合器的排放出口引導且通過混合器的排放出口並且進入與混合器的排放出口連接的排放導管中。含水泡沫能夠與混合器中和/或排放導管中的含水燒石膏漿料結合。漿料流通過排放導管，漿料流從排放導管連續地沈積到由成形台支撐的移動蓋網片材上。允許漿料在前進的網上方散佈。第二蓋網片材被施加以覆蓋漿料並且形成連續壁板預型件的夾層結構，連續壁板預型件的夾層結構經過成形，諸如在常規的成形台處，以獲得期望的厚度。燒石膏與壁板預型件中的水反應並且隨著壁板預型件沿製造線路下移而凝固。壁板預型件在沿著線路的壁板預型件已經充分凝固的點處被切割成段，段被翻轉，乾燥(例如，在焙爐中)以餾出過量的水，並且經處理以提供期望尺寸的壁板成品。 It is known to make gypsum board by uniformly dispersing calcined gypsum (commonly referred to as "stucco") into water to form an aqueous calcined gypsum slurry. typical The aqueous calcined gypsum slurry is produced in a continuous manner by placing the stucco and water and other additives in a mixer comprising means for agitating the contents to form a uniform gypsum slurry. The slurry is continuously directed toward the discharge outlet of the mixer and through the discharge outlet of the mixer and into a discharge conduit connected to the discharge outlet of the mixer. The aqueous foam can be combined with the aqueous calcined gypsum slurry in the mixer and/or in the discharge conduit. The slurry stream passes through a discharge conduit, and the slurry stream is continuously deposited from the discharge conduit onto a moving cover web sheet supported by the forming station. Allow the slurry to spread on the advancing web. A second cover web sheet is applied to cover the slurry and form a sandwich structure of continuous wall panel preforms, the sandwich structure of the continuous wall panel preform being shaped, such as at a conventional forming station, to achieve a desired thickness. The calcined gypsum reacts with the water in the siding preform and solidifies as the siding preform moves down the manufacturing line. The panel preform is cut into sections at a point along the line where the panel preform has sufficiently solidified, the section is inverted, dried (eg, in a baking furnace) to distill off excess water, and treated A finished siding of the desired size is provided.
在通過引用合併於本文中的共同受讓的美國專利5,683,635、5,643,510、6,494,609、6,874,930、7,007,914和7,296,919中公開了用於解決與石膏壁板的生產相關的一些操作問題的現有的裝置和方法。 Existing devices and methods for solving some operational problems associated with the production of gypsum wallboard are disclosed in commonly assigned U.S. Patent Nos. 5,683,635, 5,643, 510, 6, 494, 609, 6, 874, 930, 7, 007, 914 and 7,296,919.
在本領域中，水相對於被組合以形成既定量的成品的灰泥的重量比例通常被稱為“水灰泥比”(WSR)。在配方不變的情況下WSR的減小將相應地增大漿料黏度，從而降低漿料在成形臺上散佈的能力。在石膏板製造過程中減少水的使用(例如，降低WSR)能夠產生很多優點，包括降低該 過程中能量需求的可能。然而，將黏度逐増的石膏漿料均勻地散佈在成形臺上仍是巨大的難題。 In the art, the weight ratio of water to the stucco that is combined to form a quantitative amount of finished product is commonly referred to as the "water cement ratio" (WSR). The reduction in WSR with the same formulation will increase the slurry viscosity accordingly, thereby reducing the ability of the slurry to spread over the forming station. Reducing the use of water (eg, reducing WSR) during the gypsum board manufacturing process can yield a number of advantages, including reducing the The possibility of energy demand in the process. However, it is still a great problem to evenly spread the gypsum slurry having a viscosity on the forming table.
此外，在漿料為包含空氣的多相漿料的一些情形下，在混合器的漿料排放導管中會發生空氣-液態漿料分離。隨著WSR減小，空氣體積增大以保持相同的乾燥密度。從液態漿料相中分離空氣相的程度增大，從而導致傾向於較大的質量或密度變化。 Further, in some cases where the slurry is a multi-phase slurry containing air, air-liquid slurry separation may occur in the slurry discharge conduit of the mixer. As the WSR decreases, the air volume increases to maintain the same dry density. The degree of separation of the air phase from the liquid slurry phase is increased, resulting in a tendency to a greater mass or density change.

Oriented at its ends to uniformly define a generally curved wall. Moreover, the parameters used to define the particular form factor of the outer wall can depend on the specific operational parameters of the process in which the slurry distributor will be used.
饋送導管122和分佈導管128中的至少一個可以包括擴展區域，所述擴展區域具有比從饋送導管122朝向分佈導管128的方向在擴展區域上游的相鄰區域的截面流面積大的截面流面積。第一進入段136和/或第一定形管道141可以具有沿流動方向變化的截面，以幫助分佈移動通過其中的第一漿料流。定形管道141可以具有從第一饋送入口124朝向分佈導管128沿第一流動方向195增加的截面流面積，以 使得隨著第一漿料流通過第一定形管道141而減速。在一些實施方案中，第一定形管道141可以在沿第一流動方向195的預定點處具有最大截面流面積，並且進一步沿著第一流動方向195的點處從最大截面流面積減小。 At least one of the feed conduit 122 and the distribution conduit 128 may include an expanded region having a cross-sectional flow area that is larger than a cross-sectional flow area of an adjacent region upstream of the expanded region from the feed conduit 122 toward the distribution conduit 128. The first inlet section 136 and/or the first shaped conduit 141 may have a section that varies along the direction of flow to aid in distributing the first slurry stream moving therethrough. The shaped conduit 141 can have a cross-sectional flow area that increases from the first feed inlet 124 toward the distribution conduit 128 in the first flow direction 195 to The deceleration is caused as the first slurry stream passes through the first shaped conduit 141. In some embodiments, the first shaped conduit 141 can have a maximum cross-sectional flow area at a predetermined point along the first flow direction 195 and further decrease from the maximum cross-sectional flow area at a point along the first flow direction 195.
在一些實施方案中，第一定形管道141的最大截面流面積為第一饋送入口124的開口134的截面積的大約200%或更小。在其他實施方案中，第一定形管道141的最大截面流面積為第一饋送入口124的開口134的截面積的大約150%或更小。在其他的實施方案中，第一定形管道141的最大截面流面積為第一饋送入口124的開口134的截面積的大約125%或更小。在其他的實施方案中，第一定形管道141的最大截面流面積為第一饋送入口124的開口134的截面積的大約110%或更小。在一些實施方案中，控制截面流面積以使得在既定長度上流體面積不會改變大於預定量以幫助防止流態的大幅變化。 In some embodiments, the maximum cross-sectional flow area of the first shaped conduit 141 is about 200% or less of the cross-sectional area of the opening 134 of the first feed inlet 124. In other embodiments, the maximum cross-sectional flow area of the first shaped conduit 141 is about 150% or less of the cross-sectional area of the opening 134 of the first feed inlet 124. In other embodiments, the maximum cross-sectional flow area of the first shaped conduit 141 is about 125% or less of the cross-sectional area of the opening 134 of the first feed inlet 124. In other embodiments, the maximum cross-sectional flow area of the first shaped conduit 141 is about 110% or less of the cross-sectional area of the opening 134 of the first feed inlet 124. In some embodiments, the cross-sectional flow area is controlled such that the fluid area does not change by more than a predetermined amount over a given length to help prevent large variations in the flow regime.
在一些實施方案中，第一進入段136和/或第一定形管道141可以包括一個或多個引導通道167、168，引導通道167、168適於幫助將第一漿料流朝向饋送導管122的外壁157和/或內壁158分佈。引導通道167、168適於增大在漿料分佈器120的邊界壁層周圍的漿料流。 In some embodiments, the first inlet section 136 and/or the first shaped conduit 141 can include one or more guide channels 167, 168 that are adapted to help direct the first slurry stream toward the feed conduit 122 The outer wall 157 and/or the inner wall 158 are distributed. The guide channels 167, 168 are adapted to increase the flow of slurry around the boundary wall layer of the slurry distributor 120.
參照圖1和圖5，引導通道167、168能夠被構型為具有比饋送導管122的相鄰部分171大的截面積，這限定了促進到分別設置在漿料分佈器120的壁區域處的相鄰引導通道167、168的流動的限制。在圖示的實施方案中，饋送導 管122包括與分佈導管128的外壁157和側壁151相鄰的外引導通道167以及與第一定形管道141的內壁158相鄰的內引導通道168。外引導通道167和內引導通道168的截面積能夠變得沿第一流動方向195移動而逐漸變小。外引導通道167能夠基本上沿分佈導管128的側壁151延伸至分佈出口130。在沿垂直於第一流動方向195的方向上通過第一定形管道141的既定截面位置處，外引導通道167具有比內引導通道168大的截面積以幫助將第一漿料流從沿第一饋送方向190的其初始移動線路朝向外壁157轉向。 Referring to Figures 1 and 5, the guide channels 167, 168 can be configured to have a larger cross-sectional area than the adjacent portion 171 of the feed conduit 122, which defines facilitating placement to the wall regions of the slurry distributor 120, respectively. Restrictions on the flow of adjacent guide channels 167, 168. In the illustrated embodiment, the feed guide The tube 122 includes an outer guide channel 167 adjacent the outer wall 157 and the side wall 151 of the distribution conduit 128 and an inner guide channel 168 adjacent the inner wall 158 of the first shaped tube 141. The cross-sectional areas of the outer guide passage 167 and the inner guide passage 168 can become moved in the first flow direction 195 to become gradually smaller. The outer guide channel 167 can extend substantially along the sidewall 151 of the distribution conduit 128 to the distribution outlet 130. At a predetermined cross-sectional position through the first shaped conduit 141 in a direction perpendicular to the first flow direction 195, the outer guide passage 167 has a larger cross-sectional area than the inner guide passage 168 to assist in the flow of the first slurry from the first Its initial moving path of the feed direction 190 is turned toward the outer wall 157.
提供引導通道相鄰壁區域能夠幫助將漿料流通導或引導至那些區域，這些區域可以為在發現低漿料流的“死點”的常規系統中的區域。通過設置引導通道來促進在漿料分佈器120的壁區域處的漿料流，在漿料分佈器內部的漿料集聚被抑制，並且能夠增強漿料分佈器120內部的清潔。還能夠減小漿料集聚破裂成塊(這會撕裂移動的蓋網片材)的頻率。 Providing a guide channel adjacent wall region can help direct or direct slurry flow to those regions, which can be regions in conventional systems where a "dead point" of low slurry flow is found. The slurry flow at the wall region of the slurry distributor 120 is promoted by providing the guide passage, the slurry concentration inside the slurry distributor is suppressed, and the cleaning inside the slurry distributor 120 can be enhanced. It is also possible to reduce the frequency at which the slurry agglomeration breaks into a block which will tear the moving cover web sheet.
在其他實施方案中，能夠改變外引導通道167和內引導通道168的相對尺寸以幫助調節漿料流，從而提高流穩定性並且減少空氣-液態漿料相分離的發生。例如，在使用相對更黏的漿料的應用中，在沿垂直於第一流動方向195的方向通過第一定形管道141的既定截面位置處，外引導通道167能夠具有比內引導通道168更小的截面積，以幫助朝向內壁158擠壓第一漿料流。 In other embodiments, the relative dimensions of outer guide channel 167 and inner guide channel 168 can be varied to help regulate slurry flow, thereby improving flow stability and reducing the occurrence of air-liquid slurry phase separation. For example, in applications where a relatively more viscous slurry is used, the outer guiding channel 167 can have more than the inner guiding channel 168 at a given cross-sectional position through the first shaped conduit 141 in a direction perpendicular to the first flow direction 195. A small cross-sectional area is provided to help squeeze the first slurry stream toward the inner wall 158.
第一和第二定形管道141、142的內彎曲壁158 會和以限定在分佈導管128的進入部152近處的尖峰部175。尖峰部175使連接器段139有效地分叉。每個饋送出口140、145與分佈導管128的進入部152流體連通。 Inner curved wall 158 of first and second shaped conduits 141, 142 There will be a peak portion 175 defined in proximity to the entry portion 152 of the distribution conduit 128. The spike 175 effectively branches the connector segment 139. Each feed outlet 140, 145 is in fluid communication with an inlet 152 of the distribution conduit 128.
在其他實施方案中，尖峰部175沿縱軸線50的位置能夠改變。例如，在其他實施方案中，第一和第二定形管道141、142的內彎曲壁158可以不太彎曲以使尖峰部175比如圖所示在圖示的漿料分佈器120中沿縱軸線50更遠離分佈出口130。在其他實施方案中，尖峰部175能夠比如圖所示在圖示的漿料分佈器120中沿縱軸線50更靠近分佈出口130。 In other embodiments, the position of the peak 175 along the longitudinal axis 50 can vary. For example, in other embodiments, the inner curved walls 158 of the first and second shaped conduits 141, 142 may be less curved such that the peaks 175, such as shown in the illustrated slurry distributor 120, along the longitudinal axis 50 Farther away from the distribution exit 130. In other embodiments, the spikes 175 can be closer to the distribution outlet 130 along the longitudinal axis 50 in the illustrated slurry distributor 120 as shown.
分佈導管128與由縱軸線50和橫軸線60限定的平面57基本上平行且適於將組合的第一和第二含水燒石膏漿料流從第一和第二定形管道141、142推擠到大致兩維的流動模式，用於增強穩定性和均勻度。分佈出口130具有沿著橫軸線60延伸預定距離的寬度以及沿垂直軸線55延伸的高度，垂直軸線55與縱軸線50和橫軸線60相對垂直。分佈出口130的高度相對於其寬度較小。分佈導管128可以相對於成型臺上的移動的蓋網片取向以使分佈導管128與移動的網基本上平行。 The distribution conduit 128 is substantially parallel to the plane 57 defined by the longitudinal axis 50 and the transverse axis 60 and is adapted to push the combined first and second aqueous calcined gypsum slurry streams from the first and second shaped conduits 141, 142 to A roughly two-dimensional flow pattern for enhanced stability and uniformity. The distribution outlet 130 has a width that extends a predetermined distance along the transverse axis 60 and a height that extends along the vertical axis 55 that is relatively perpendicular to the longitudinal axis 50 and the transverse axis 60. The height of the distribution outlet 130 is small relative to its width. The distribution conduit 128 can be oriented relative to the moving cover web on the forming station such that the distribution conduit 128 is substantially parallel to the moving web.
分佈導管128大致沿縱軸線50延伸並且包括進入部152和分佈出口130。進入部152與饋送導管122的第一和第二饋送入口124、125流體連通。參照圖5，進入部152適於接收來自饋送導管122的第一和第二饋送入口124、125的第一和第二含水燒石膏漿料流兩者。分佈導管128的進入部152包括分佈入口154，分佈入口154與饋送導管122的第 一和第二饋送出口140、145流體連通。圖示的分佈入口154限定了與第一和第二饋送出口140、145的開口142基本對應的開口156。第一和第二含水燒石膏漿料流在分佈導管128中組合，以使組合流大致沿出口流動方向192移動，在壁板製造線路中，出口流動方向192能夠與在成型臺上移動的蓋網片材的移動線路基本上對準。 The distribution conduit 128 extends generally along the longitudinal axis 50 and includes an inlet portion 152 and a distribution outlet 130. The inlet portion 152 is in fluid communication with the first and second feed inlets 124, 125 of the feed conduit 122. Referring to Figure 5, the inlet portion 152 is adapted to receive both the first and second aqueous calcined gypsum slurry streams from the first and second feed inlets 124, 125 of the feed conduit 122. The inlet portion 152 of the distribution conduit 128 includes a distribution inlet 154, a distribution inlet 154 and a feed conduit 122 One is in fluid communication with the second feed outlets 140, 145. The illustrated distribution inlet 154 defines an opening 156 that substantially corresponds to the opening 142 of the first and second feed outlets 140, 145. The first and second aqueous calcined gypsum slurry streams are combined in a distribution conduit 128 such that the combined flow moves generally along the outlet flow direction 192, and in the wallboard manufacturing circuit, the outlet flow direction 192 can be moved with the cover moving over the forming station The moving lines of the web sheet are substantially aligned.
分佈出口130與進入部152流體連通，並且因此與饋送導管122的第一和第二饋送入口124、125以及第一和第二饋送出口140、145流體連通。分佈出口130與第一和第二定形管道141、143流體連通並且適於在蓋網片材沿機器方向50前進時沿著出口流動方向192將組合的第一和第二漿料流從其中排出。 The distribution outlet 130 is in fluid communication with the inlet portion 152 and thus with the first and second feed inlets 124, 125 of the feed conduit 122 and the first and second feed outlets 140, 145. The distribution outlet 130 is in fluid communication with the first and second shaped conduits 141, 143 and is adapted to discharge the combined first and second slurry streams from the outlet web flow direction 192 as the cover web sheet advances in the machine direction 50 .
參照圖1，圖示的分佈出口130限定了具有半圓形窄端183、185的大致矩形的開口181。分佈出口130的開口181的半圓形端183、185可以為與分佈導管128的側壁151、153相鄰設置的外引導通道167的終止端。 Referring to Figure 1, the illustrated distribution outlet 130 defines a generally rectangular opening 181 having semi-circular narrow ends 183,185. The semicircular ends 183, 185 of the opening 181 of the distribution outlet 130 may be the terminating ends of the outer guiding passages 167 disposed adjacent to the side walls 151, 153 of the distribution conduit 128.

The front slag surface layer/hard edge stream 1049 (the denser aqueous calcined gypsum slurry layer relative to at least one of the first and second aqueous calcined gypsum slurry streams) can be applied to the hard relative to the machine direction 1092 The first moving web 1039 upstream of the edge/front slag surface roller 1031 applies a slag surface layer to the first web 1039 and defines the hard edge of the panel.
第一含水燒石膏漿料流1047和第二含水燒石膏漿料流1048分別通過漿料分佈器1020的第一饋送入口1024和第二饋送入口1025。第一和第二含水燒石膏漿料流1047、1048在漿料分佈器1020中組合。第一和第二含水燒石膏漿料流1047、1048以流線型流的方式沿著流路移動通過漿料分佈器1020，經過最小的或基本上不經過空氣-液態漿料相分離且基本上不經過渦流流路。 The first aqueous calcined gypsum slurry stream 1047 and the second aqueous calcined gypsum slurry stream 1048 pass through a first feed inlet 1024 and a second feed inlet 1025 of the slurry distributor 1020, respectively. The first and second aqueous calcined gypsum slurry streams 1047, 1048 are combined in a slurry distributor 1020. The first and second aqueous calcined gypsum slurry streams 1047, 1048 are moved in a streamlined manner along the flow path through the slurry distributor 1020, with minimal or substantially no air-liquid slurry phase separation and substantially no After the vortex flow path.
第一移動網1039沿著縱軸線50移動。第一含水燒石膏漿料流1047通過第一饋送入口1024，並且第二含水燒石膏漿料流1048通過第二饋送入口1025。分佈導管1028被定位成使得其沿縱軸線50延伸，縱軸線50與機器方向1092 基本上重合，第一蓋網片材1039沿機器方向1092移動。較好地，分佈出口1030的中央中點(沿橫軸線/橫越機器方向60截取)與第一移動蓋片材1039的中央中點基本上重合。第一和第二含水燒石膏漿料流1047、1048在漿料分佈器1020中組合，以使組合的第一和第二含水燒石膏漿料流1051大致沿著機器方向1092在分佈方向1093上通過分佈出口1030。 The first moving net 1039 moves along the longitudinal axis 50. The first aqueous calcined gypsum slurry stream 1047 passes through the first feed inlet 1024 and the second aqueous calcined gypsum slurry stream 1048 passes through the second feed inlet 1025. The distribution conduit 1028 is positioned such that it extends along the longitudinal axis 50, the longitudinal axis 50 and the machine direction 1092 Substantially coincident, the first cover web sheet 1039 moves in the machine direction 1092. Preferably, the central midpoint of the distribution outlet 1030 (taken along the transverse axis/crossing machine direction 60) substantially coincides with the central midpoint of the first moving cover sheet 1039. The first and second aqueous calcined gypsum slurry streams 1047, 1048 are combined in a slurry distributor 1020 such that the combined first and second aqueous calcined gypsum slurry streams 1051 are generally distributed along the machine direction 1092 in the direction of distribution 1093. By distributing the outlet 1030.
在一些實施方案中，分佈導管1028被定位成使得其與由沿成型台移動的第一網1039的縱軸線50和橫軸線60限定的平面基本上平行。在其他實施方案中，分佈導管的進入部能夠被設置為在垂直方向上相對於第一網1039比分佈出口1030較低或較高。 In some embodiments, the distribution conduit 1028 is positioned such that it is substantially parallel to a plane defined by the longitudinal axis 50 and the transverse axis 60 of the first web 1039 moving along the forming station. In other embodiments, the inlet portion of the distribution conduit can be configured to be lower or taller relative to the first outlet 1030 than the distribution outlet 1030 in the vertical direction.
組合的第一和第二含水燒石膏漿料流1051從漿料分佈器1020排出到第一移動網1039上。正面撇渣面層/硬邊緣流1049能夠在第一和第二含水燒石膏漿料流1047、1048從漿料分佈器1020排出的在機器方向1092上相對於第一移動網1039的移動方向上游的點處從混合器1012中沈積到第一移動網1039上。相對於常規的進料斗設計，組合的第一和第二含水燒石膏漿料流1047、1048能夠沿橫越機器方向以減小的每單位動量從漿料分佈器中排出，以有助於防止沈積到第一移動網1039上的正面撇渣面層/硬邊緣流1049的“沖去”(回應於沈積到其上漿料的衝擊，沈積的撇渣面層的部分從其在移動網339上的位置移位的情形)。 The combined first and second aqueous calcined gypsum slurry streams 1051 are discharged from the slurry distributor 1020 onto the first mobile web 1039. The front slag layer/hard edge stream 1049 can be upstream of the first and second aqueous calcined gypsum slurry streams 1047, 1048 from the slurry distributor 1020 in the machine direction 1092 relative to the first moving web 1039. The point is deposited from the mixer 1012 onto the first mobile net 1039. The combined first and second aqueous calcined gypsum slurry streams 1047, 1048 can be discharged from the slurry distributor in a cross-machine direction with reduced per unit momentum relative to a conventional feed hopper design to help prevent The "flush" of the front slag layer/hard edge stream 1049 deposited onto the first moving web 1039 (in response to the impact deposited onto the slurry, the portion of the deposited slag layer from which it is on the moving web 339 The situation of position shift on).
能夠通過至少一個流調整元件1023來選擇性地控制分別通過漿料分佈器1020的第一和第二饋送入口1024、 1025的第一和第二含水燒石膏漿料流1047、1048。例如，在一些實施方案中，選擇性地控制第一和第二含水燒石膏漿料流1047、1048，以使得通過第一饋送入口1024的第一含水燒石膏漿料流1047的平均速度與通過第二饋送入口1025的第二含水燒石膏漿料流1048的平均速度基本上相等。 The first and second feed inlets 1024, respectively, through the slurry distributor 1020 can be selectively controlled by at least one flow adjustment element 1023, First and second aqueous calcined gypsum slurry streams 1047, 1048. For example, in some embodiments, the first and second aqueous calcined gypsum slurry streams 1047, 1048 are selectively controlled such that the average velocity and passage of the first aqueous calcined gypsum slurry stream 1047 through the first feed inlet 1024 The average velocity of the second aqueous calcined gypsum slurry stream 1048 of the second feed inlet 1025 is substantially equal.
在實施方案中，第一含水燒石膏漿料流1047以平均第一饋送速度通過漿料分佈器1020的第一饋送入口1024。第二含水燒石膏漿料流1048以平均第二饋送速度通過漿料分佈器1020的第二饋送入口1025。第二饋送入口1025與第一饋送入口1024成間隔關係。第一和第二含水燒石膏漿料流1051在漿料分佈器1020中組合。組合的第一和第二含水燒石膏漿料流1051以平均排出速度從漿料分佈器1020的分佈出口1030排出到沿機器方向1092移動的蓋網片材1039上。平均排出速度小於平均第一饋送速度和平均第二饋送速度。 In an embodiment, the first aqueous calcined gypsum slurry stream 1047 passes through the first feed inlet 1024 of the slurry distributor 1020 at an average first feed rate. The second aqueous calcined gypsum slurry stream 1048 passes through the second feed inlet 1025 of the slurry distributor 1020 at an average second feed rate. The second feed inlet 1025 is in spaced relationship with the first feed inlet 1024. The first and second aqueous calcined gypsum slurry streams 1051 are combined in a slurry distributor 1020. The combined first and second aqueous calcined gypsum slurry streams 1051 are discharged from the distribution outlet 1030 of the slurry distributor 1020 to the cover web sheet 1039 moving in the machine direction 1092 at an average discharge speed. The average discharge speed is less than the average first feed speed and the average second feed speed.
在一些實施方案中，平均排出速度小於平均第一饋送速度和平均第二饋送速度的大約90%。在一些實施方案中，平均排出速度小於平均第一饋送速度和平均第二饋送速度的大約80%。 In some embodiments, the average discharge speed is less than about 90% of the average first feed speed and the average second feed speed. In some embodiments, the average discharge speed is less than about 80% of the average first feed speed and the average second feed speed.
組合的第一和第二含水燒石膏漿料流1051通過分佈出口1030從漿料分佈器1020中排出。分佈出口1030的開口具有沿橫軸線60延伸的寬度並且定尺寸以使第一移動蓋網片材1039的寬度與分佈出口1030的開口的寬度之比在大約1：1和大約6：1之間且包含這些的範圍內。在一些實施 方案中，從漿料分佈器1020排出的組合的第一和第二含水燒石膏漿料流1051的平均速度與沿機器方向1092移動的移動蓋網片材1039的速度之比在一些實施方案中可以為大約2：1或更小，並且在其他實施方案中可以從大約1：1至大約2：1。 The combined first and second aqueous calcined gypsum slurry streams 1051 are discharged from the slurry distributor 1020 through a distribution outlet 1030. The opening of the distribution outlet 1030 has a width extending along the transverse axis 60 and is sized such that the ratio of the width of the first moving cover web sheet 1039 to the width of the opening of the distribution outlet 1030 is between about 1:1 and about 6:1. And include these within the scope. In some implementations In the solution, the ratio of the average speed of the combined first and second aqueous calcined gypsum slurry streams 1051 discharged from the slurry distributor 1020 to the speed of the moving cover web sheet 1039 moving in the machine direction 1092 is in some embodiments. It can be about 2: 1 or less, and in other embodiments can be from about 1:1 to about 2:1.
從漿料分佈器1020排出的組合的第一和第二含水燒石膏漿料流1051在移動網1039上形成散佈模式。能夠調節分佈出口1030的尺寸和形狀中的至少一個，這依次能夠改變散佈模式。 The combined first and second aqueous calcined gypsum slurry streams 1051 discharged from the slurry distributor 1020 form a scatter pattern on the moving web 1039. At least one of the size and shape of the distribution outlet 1030 can be adjusted, which in turn can change the dispersion pattern.
因此，漿料被饋送到饋送導管1022的兩個饋送入口1024、1025中並且然後以可調整間隙通過分佈出口1030離開。聚合部1082能夠提供漿料速度的略微增加，從而減少不期望的離開效果並且因此進一步提高自由表面處的流動穩定性。通過利用成形系統在排放出口1030處進行橫越機器(CD)成形控制，能夠減少側至側流動變化和/或任何局部變化。該分佈系統能夠幫助防止漿料中的空氣-液態漿料分離，使得輸送到成型台1038的材料更均勻且一致。 Thus, the slurry is fed into the two feed inlets 1024, 1025 of the feed conduit 1022 and then exits through the distribution outlet 1030 with an adjustable gap. The polymerization portion 1082 can provide a slight increase in slurry velocity, thereby reducing undesirable exit effects and thus further improving flow stability at the free surface. By performing a cross machine (CD) forming control at the discharge outlet 1030 using a forming system, side to side flow variations and/or any local variations can be reduced. The distribution system can help prevent separation of the air-liquid slurry in the slurry such that the material delivered to the forming station 1038 is more uniform and uniform.
背面撇渣面層流1053(相對於第一和第二含水燒石膏漿料流1047、1048中的至少一個更稠密的含水燒石膏漿料層)能夠施加到第二移動網1043上。背面撇渣面層流1053能夠在背面撇渣面層輥1037的相對於第二移動網1043的移動方向上游的點處從混合器1012中沈積。 A back slag laminar flow 1053 (relative to at least one of the first and second aqueous calcined gypsum slurry streams 1047, 1048, which is more dense aqueous calcined gypsum slurry) can be applied to the second mobile web 1043. The back slag laminar flow 1053 can be deposited from the mixer 1012 at a point upstream of the slag slag roll 1037 relative to the direction of movement of the second moving web 1043.
在其他實施方案中，第一和第二含水燒石膏漿料流1047、1048的平均速度會變化。在一些實施方案中，饋送導管1022的饋送入口1024、1025處的漿料速度能夠在相對 較高和較低的平均速度之間周期性地振蕩(在一個時間點處，一個入口比另一個入口具有較高的速度，然後在預定時間點處則相反)，以有助於降低在其幾何結構內集聚的可能。 In other embodiments, the average velocity of the first and second aqueous calcined gypsum slurry streams 1047, 1048 may vary. In some embodiments, the slurry velocity at the feed inlets 1024, 1025 of the feed conduit 1022 can be relative Periodically oscillate between higher and lower average speeds (at one point in time, one inlet has a higher velocity than the other inlet and then opposite at a predetermined point in time) to help reduce The possibility of agglomeration within the geometry.
在實施方案中，通過第一饋送入口1024的第一含水燒石膏漿料流1047具有比從分佈出口1030排出的組合的第一和第二流1051的剪切速率低的剪切速率，並且通過第二饋送入口1025的第二含水燒石膏漿料流1048具有比從分佈出口1030排出的組合的第一和第二流1051的剪切速率低的剪切速率。在實施方案中，從分佈出口1030排出的組合的第一和第二流1051的剪切速率能夠大於通過第一饋送入口1024的第一含水燒石膏漿料1047和/或通過第二饋送入口1025的第二含水燒石膏漿料流1048的剪切速率的大約150%，在另外其他的實施方案中大於大約175%，並且在另外的實施方案中大於兩倍或比其大。應當理解，第一和第二含水燒石膏漿料流1047、1048和組合的第一和第二流1051的黏度能夠與既定位置處存在的剪切速率反相關，以使得隨著剪切速率上升，黏度減小。 In an embodiment, the first aqueous calcined gypsum slurry stream 1047 through the first feed inlet 1024 has a lower shear rate than the combined first and second streams 1051 exiting the distribution outlet 1030, and passes The second aqueous calcined gypsum slurry stream 1048 of the second feed inlet 1025 has a lower shear rate than the combined first and second streams 1051 exiting the distribution outlet 1030. In an embodiment, the shear rate of the combined first and second streams 1051 discharged from the distribution outlet 1030 can be greater than the first aqueous calcined gypsum slurry 1047 passing through the first feed inlet 1024 and/or through the second feed inlet 1025. The shear rate of the second aqueous calcined gypsum slurry stream 1048 is about 150%, in still other embodiments greater than about 175%, and in other embodiments greater than two times or greater. It will be appreciated that the viscosity of the first and second aqueous calcined gypsum slurry streams 1047, 1048 and the combined first and second streams 1051 can be inversely related to the shear rate present at a given location such that as the shear rate increases The viscosity is reduced.
在實施方案中，通過第一饋送入口1024的第一含水燒石膏漿料流1047具有比從分佈出口1030排出的組合的第一和第二流1051的剪切應力低的剪切應力，並且通過第二饋送入口1025的第二含水燒石膏漿料流1048具有比從分佈出口1030排出的組合的第一和第二流1051的剪切應力低的剪切應力。在實施方案中，從分佈出口1030排出的組合的第一和第二流1051的剪切應力能夠大於通過第一饋送入口 1024的第一含水燒石膏漿料流1047和/或通過第二饋送入口1025的第二含水燒石膏漿料流1048的剪切速率的大約110%。 In an embodiment, the first aqueous calcined gypsum slurry stream 1047 through the first feed inlet 1024 has a lower shear stress than the combined first and second streams 1051 discharged from the distribution outlet 1030, and passes The second aqueous calcined gypsum slurry stream 1048 of the second feed inlet 1025 has a lower shear stress than the combined first and second streams 1051 discharged from the distribution outlet 1030. In an embodiment, the shear stress of the combined first and second streams 1051 discharged from the distribution outlet 1030 can be greater than through the first feed inlet The first aqueous calcined gypsum slurry stream 1047 of 1024 and/or the shear rate of the second aqueous calcined gypsum slurry stream 1048 through the second feed inlet 1025 is about 110%.
在實施方案中，通過第一饋送入口1024的第一含水燒石膏漿料流1047具有比從分佈出口1030排出的組合的第一和第二流1051的雷諾數高的雷諾數，並且通過第二饋送入口1025的第二含水燒石膏漿料流1048具有比從分佈出口1030排出的組合的第一和第二流1051的雷諾數高的雷諾數。在實施方案中，從分佈出口1030排出的組合的第一和第二流1051的雷諾數能夠小於通過第一饋送入口1024的第一含水燒石膏漿料流1047和/或通過第二饋送入口1025的第二含水燒石膏漿料流1048的雷諾數的大約90%，在另外其他實施方案中小於大約80%，並且在另外的實施方案中小於大約70%。 In an embodiment, the first aqueous calcined gypsum slurry stream 1047 through the first feed inlet 1024 has a Reynolds number that is higher than the Reynolds number of the combined first and second streams 1051 exiting from the distribution outlet 1030, and passes through the second The second aqueous calcined gypsum slurry stream 1048 of the feed inlet 1025 has a Reynolds number that is higher than the Reynolds number of the combined first and second streams 1051 exiting from the distribution outlet 1030. In an embodiment, the combined first and second streams 1051 exiting the distribution outlet 1030 can have a Reynolds number that is less than the first aqueous calcined gypsum slurry stream 1047 through the first feed inlet 1024 and/or through the second feed inlet 1025. The second aqueous calcined gypsum slurry stream 1048 has a Reynolds number of about 90%, in still other embodiments less than about 80%, and in still other embodiments less than about 70%.

The flow splitter 1100 can be placed in fluid communication with the gypsum slurry mixer and the slurry distributor such that the flow splitter 1100 receives a single aqueous calcined gypsum slurry stream from the mixer and from which two separate aqueous calcined gypsum slurry The stream is discharged to the first and second feed inlets of the slurry distributor. One or more flow conditioning elements can be disposed between the mixer and splitter 1100 and/or between one or both of the transfer branches that are routed between the splitter 1100 and the associated slurry distributor.
分流器1100具有設置在主分支1103中的基本圓形的入口1102和分別設置在第一和第二出口分支1105、1107 中的一對基本圓形的出口1104、1106，主分支1103適於接收單一漿料流，出口1104、1106允許兩股漿料流從分流器1100中排出。入口1102和出口1104、1106的開口的截面積能夠根據所期望的流速來改變。在出口1104、1106的開口的截面積分別與入口1102的開口的截面積基本相等的實施方案中，從每個出口1104、1106排出的漿料的流速能夠減至進入入口1102的單一漿料流的速度的大約50%，其中通過入口1102和兩個出口1104、1106的體積流率基本相同。 The splitter 1100 has a substantially circular inlet 1102 disposed in the main branch 1103 and is disposed at the first and second outlet branches 1105, 1107, respectively. A pair of substantially circular outlets 1104, 1106, the main branch 1103 is adapted to receive a single slurry stream, and the outlets 1104, 1106 allow two streams of slurry to be discharged from the splitter 1100. The cross-sectional area of the opening of the inlet 1102 and the outlets 1104, 1106 can vary depending on the desired flow rate. In embodiments where the cross-sectional areas of the openings of the outlets 1104, 1106 are substantially equal to the cross-sectional areas of the openings of the inlets 1102, respectively, the flow rate of the slurry discharged from each of the outlets 1104, 1106 can be reduced to a single slurry stream entering the inlet 1102. Approximately 50% of the speed, wherein the volumetric flow rates through the inlet 1102 and the two outlets 1104, 1106 are substantially the same.
在一些實施方案中，能夠使得出口1104、1106的直徑比入口1102的直徑小，從而在整個分流器1100中保持相對高的流速。在出口1104、1106的開口的截面積分別比入口1102的開口的截面積小的實施方案中，在出口1104、1106中保持流速，或者流速至少在比出口1104、1106和入口1102均具有基本相等的截面積的情況更輕的程度上減小。例如，在一些實施方案中，分流器1100具有入口1102，入口1102具有大約3英寸的內直徑(ID1)，並且每個出口1104、1106均具有大約2.5英寸的ID2(但是在其他實施方案中能夠使用其他入口和出口直徑)。在350fpm的線速度下具有這些尺寸的實施方案中，出口1104、1106的更小的直徑使得在每個出口處的流速減小了在入口1102的單一漿料流的流速的大約28%。 In some embodiments, the diameter of the outlets 1104, 1106 can be made smaller than the diameter of the inlet 1102 to maintain a relatively high flow rate throughout the splitter 1100. In embodiments where the cross-sectional areas of the openings of the outlets 1104, 1106 are smaller than the cross-sectional areas of the openings of the inlet 1102, respectively, the flow rate is maintained in the outlets 1104, 1106, or the flow rate is at least substantially equal to the outlets 1104, 1106 and the inlet 1102. The case of the cross-sectional area is reduced to a lesser extent. For example, in some embodiments, the splitter 1100 has an inlet 1102 having an inner diameter (ID 1 ) of approximately 3 inches, and each outlet 1104, 1106 has an ID 2 of approximately 2.5 inches (but in other embodiments) Other inlet and outlet diameters can be used). In embodiments having these dimensions at a line speed of 350 fpm, the smaller diameter of the outlets 1104, 1106 is such that the flow rate at each outlet is reduced by approximately 28% of the flow rate of the single slurry stream at the inlet 1102.
分流器110可以包括中央輪廓部1114以及在第一和第二出口分支1105、1107之間的接合部1120。中央輪廓部1114在分流器1100的位於接合部1120上游的中央內部區 域中形成限制部1108，限制部1108幫助促進到分流器的外邊緣1110、1112的流動以減少在接合部1120處發生漿料集聚。中央輪廓部1114的形狀使得在分流器1100的外邊緣1110、1112的鄰近處形成引導通道1111、1113。中央輪廓部1114中的限制部1108具有比引導通道1111、1113的高度H3較小的高度H2。引導通道1111、1113具有比中央限制部1108的截面積大的截面積。結果，與通過中央限制部1108相比，流動的漿料通過引導通道1111、1113遇到較小的流動阻力，並且朝向分流器接合部1120的外邊緣導流。 The splitter 110 can include a central profile 1114 and a joint 1120 between the first and second outlet branches 1105, 1107. The central profile 1114 forms a restriction 1108 in the central interior region of the splitter 1100 upstream of the joint 1120, the restriction 1108 helping to facilitate flow to the outer edges 1110, 1112 of the splitter to reduce slurry formation at the joint 1120 Gathering. The central profile 1114 is shaped such that guide channels 1111, 1113 are formed adjacent the outer edges 1110, 1112 of the diverter 1100. Restriction profile of the central portion 1114 of the guide 1108 has a smaller passage than the height H 1111,1113 height of 3 H 2. The guide passages 1111, 1113 have a cross-sectional area larger than the cross-sectional area of the central restriction portion 1108. As a result, the flowing slurry encounters less flow resistance through the guide passages 1111, 1113 than the central restriction portion 1108 and is directed toward the outer edge of the diverter joint 1120.
接合部1120建立了通往第一和第二出口分支1105、1107的開口。接合部1120由與入口流動方向1125基本垂直的平面壁表面1123構成。 The joint 1120 establishes an opening to the first and second outlet branches 1105, 1107. The joint 1120 is constituted by a planar wall surface 1123 that is substantially perpendicular to the inlet flow direction 1125.
參照圖64，在一些實施方案中，用於在可調節的且規則的時間間隔擠壓分流器1100的自動化裝置1150能夠被設置以防止固體集聚在分流器1100的內部。在一些實施方案中，擠壓裝置1150可以包括設置在中央輪廓部1114的相對側1142、1143上的一對板1152、1154。板1152、1154能夠借助適當的致動器1160相對於彼此移動。致動器1160能夠自動地或選擇性地***作以使板1152、1154相對於彼此一起移動，從而在中央輪廓部1114和接合部1120將壓縮力施加到分流器1100上。 Referring to Figure 64, in some embodiments, an automated device 1150 for squeezing the flow splitter 1100 at an adjustable and regular time interval can be configured to prevent solids from collecting inside the flow splitter 1100. In some embodiments, the pressing device 1150 can include a pair of plates 1152, 1154 disposed on opposite sides 1142, 1143 of the central profile portion 1114. The plates 1152, 1154 can be moved relative to each other by means of a suitable actuator 1160. The actuator 1160 can be operated automatically or selectively to move the plates 1152, 1154 together relative to each other to apply a compressive force to the splitter 1100 at the central profile 1114 and the joint 1120.
當擠壓裝置1150擠壓分流器時，擠壓動作向分流器1100施加壓縮力，分流器1100作為回應而向內屈曲。該壓縮力能夠有助於防止固體在分流器1100內部集聚，固體 在分流器1100內部集聚會破壞通過出口1104、1106到漿料分佈器的基本上均等的分流。在一些實施方案中，擠壓裝置1150被設計為通過使用可操作地設置有致動器的可程式控制器而自動地脈動。能夠調節通過擠壓裝置1150施加壓縮力的持續時間和/或脈動之間的間隔。此外，能夠調節板1152、1154沿壓縮方向相對於彼此行進的行程長度。 When the squeezing device 1150 squeezes the splitter, the squeezing action applies a compressive force to the splitter 1100, which in turn responds inwardly. This compressive force can help prevent solids from accumulating inside the splitter 1100, solid The gathering within the splitter 1100 breaks the substantially equal split through the outlets 1104, 1106 to the slurry distributor. In some embodiments, the squeezing device 1150 is designed to automatically pulsate by using a programmable controller that is operatively provided with an actuator. The duration of application of the compressive force by the squeezing device 1150 and/or the spacing between pulsations can be adjusted. Furthermore, it is possible to adjust the stroke length of the plates 1152, 1154 traveling relative to each other in the compression direction.

本文提供了漿料分佈器、膠結漿料混合分佈組件及其使用方法的實施方案，其能夠提供有助於在商業設置中製造諸如石膏壁板的膠結產品的許多增強的工藝特徵。依照本公開原理構形的漿料分佈器能夠在移動蓋網片材朝向成型站經過位於製造線路的濕端處的混合器時有利於含水燒石膏漿料在移動的蓋網片材上的散佈。 Provided herein are embodiments of a slurry distributor, a cementitious slurry mixing distribution assembly, and methods of use thereof that are capable of providing a number of enhanced process features that facilitate the manufacture of cementitious products such as gypsum wallboard in commercial settings. A slurry distributor configured in accordance with the principles of the present disclosure facilitates the dispersion of aqueous calcined gypsum slurry on a moving cover web sheet as the moving cover web sheet passes through a mixer located at the wet end of the manufacturing line toward the forming station .
依照本公開原理構形的石膏漿料混合分佈組件能夠將來自混合器的含水燒石膏漿料流***成兩股單獨的含水燒石膏漿料流，在依照本公開原理構形的漿料分佈器的下游兩股單獨的含水燒石膏漿料流能夠再次組合以提供期望的散佈模式。雙入口構形和分佈出口的設計能夠允許更黏稠的漿料沿橫越機器方向在移動的蓋網片材上的更寬的散佈。漿料分佈器能夠適於使得兩股單獨的含水燒石膏漿料流沿著包含橫越機器方向分量的饋送入口方向進入漿料分佈器，在漿料分佈器內被更改方向以使兩股漿料流基本上沿機器方向移動，並且以提高從漿料分佈器的分佈出口排出的組合的含水燒石膏漿料流的橫越方向均勻度從而有助於減少沿橫軸線或橫越機器方向隨時間的質量流變化的方式在分佈器中再次組合。沿包含橫越機器方向分量的第一和第二饋送方向引導第一和第二含水燒石膏漿料流能夠有助於再次組合的漿料流以減小的動量和/或能量從漿料分佈器中排出。 A gypsum slurry mixing distribution assembly configured in accordance with the principles of the present disclosure is capable of splitting an aqueous calcined gypsum slurry stream from a mixer into two separate aqueous calcined gypsum slurry streams, a slurry distributor configured in accordance with the principles of the present disclosure. The downstream two separate streams of aqueous calcined gypsum slurry can be combined again to provide the desired mode of dispersion. The dual inlet configuration and the distribution outlet design allow for a wider dispersion of the more viscous slurry along the cross machine direction on the moving web sheet. The slurry distributor can be adapted to cause two separate aqueous calcined gypsum slurry streams to enter the slurry distributor in a feed inlet direction comprising a cross-machine direction component, the direction being altered within the slurry distributor to cause two pulps The stream moves substantially in the machine direction and increases the traverse uniformity of the combined aqueous calcined gypsum slurry stream exiting the distribution outlet of the slurry distributor to help reduce along the transverse axis or across the machine direction The way the mass flow of time changes is combined again in the distributor. Directing the first and second aqueous calcined gypsum slurry streams along the first and second feed directions comprising cross-machine direction components can facilitate recombination of the slurry stream with reduced momentum and/or energy distribution from the slurry Discharged from the device.
漿料分佈器的內部流動空腔能夠被構形為使得兩股漿料流中的每股均以流線型流動通過漿料分佈器。漿料分佈器的內部流動空腔能夠被構形為使得兩股漿料流中的每股均以最小的或基本上空氣-液態漿料相分離移動通過漿料分佈器。漿料分佈器的內部流動空腔能夠被構形為使得兩股漿料流中的每股均在基本上不經過渦流流路的情況下移動通過漿料分佈器。 The internal flow cavity of the slurry distributor can be configured such that each of the two slurry streams flows in a streamlined manner through the slurry distributor. The internal flow cavity of the slurry distributor can be configured such that each of the two streams of slurry moves through the slurry distributor with a minimum or substantially air-liquid slurry phase separation. The internal flow cavity of the slurry distributor can be configured such that each of the two streams of slurry moves through the slurry distributor without substantially passing through the vortex flow path.
依照本公開原理構形的石膏漿料混合分佈組件可以包括位於漿料分佈器的分佈出口上游的流動幾何結構以在一個或多個步驟中降低漿料速度。例如，分流器能夠設置在混合器和漿料分佈器之間以降低進入漿料分佈器的漿料速度。作為另一實施例，在石膏漿料混合分佈組件中的流動幾何結構能夠包括位於漿料分佈器上游且在漿料分佈器內的擴展區域以使漿料放緩，因此當其從漿料分佈器的分佈出口排出時是可掌控的。 A gypsum slurry mixing distribution assembly configured in accordance with the principles of the present disclosure may include a flow geometry located upstream of the distribution outlet of the slurry distributor to reduce the slurry velocity in one or more steps. For example, a flow splitter can be placed between the mixer and the slurry distributor to reduce the slurry velocity entering the slurry distributor. As another example, the flow geometry in the gypsum slurry mixing distribution assembly can include an extended region located upstream of the slurry distributor and within the slurry distributor to slow the slurry, thus when it is distributed from the slurry The distribution outlet of the device is controllable when it is discharged.
分佈出口的幾何結構還能夠有助於控制在漿料從漿料分佈器排出到移動的蓋網片材上時漿料的排出速度和動量。漿料分佈器的流動幾何結構能夠適合使得從分佈出口排出的漿料以與在橫越機器方向上更寬的出口相比具有相對較小高度的基本兩維流動模式保持以有助於提高穩定性和均勻度。 The geometry of the distribution outlet can also help control the rate and momentum of slurry discharge as the slurry is discharged from the slurry distributor onto the moving cover web. The flow geometry of the slurry distributor can be adapted such that the slurry discharged from the distribution outlet is maintained in a substantially two-dimensional flow pattern having a relatively small height compared to a wider outlet in the cross-machine direction to help improve stability Sex and uniformity.
在相似操作條件下，與從常規的進料斗排出的漿料的每單位寬度動量相比，相對寬的排放出口產生了從分佈出口排出的漿料的較低的每單位寬度動量。降低的每單位寬 度動量能夠有助於防止在漿料從漿料分佈器排出到網上的位置的上游施加到蓋網片材上的稠密層的撇渣面層的沖去。 Under similar operating conditions, a relatively wide discharge outlet produces a lower momentum per unit width of the slurry discharged from the distribution outlet as compared to the momentum per unit width of the slurry discharged from a conventional feed hopper. Reduced per unit width The momentum can help prevent flushing of the slag layer applied to the dense layer on the cover web upstream of the location where the slurry is discharged from the slurry distributor to the web.
在使用6英寸寬且2英寸厚的常規進料斗出口的情形下，對於大體積產品而言出口的平均速度能夠為大約761ft/min。在依照本公開原理構形的漿料分佈器包括具有24英寸寬且0.75英寸厚的開口的分佈出口的實施方案中，平均速度能夠為大約550ft/min。對於兩個裝置而言，質量流率相同，均為3,437lb/min。對於兩種情況而言，漿料的動量(質量流率*平均速度)對於常規的進料斗和漿料分佈器分別為~2,618,000和1,891,000lb．ft/min2。將相對應的計算出的動量除以常規的進料斗出口和漿料分佈器出口的寬度，從常規的進料斗排出的漿料的每單位寬度動量為402,736(lb．ft/min2)/(橫過進料斗寬度的英寸)，並且從依照本公開原理構形的漿料分佈器排出的漿料的每單位寬度動量為78,776(lb．ft/min2)/(橫過漿料分佈器寬度的英寸)。在該情況下，從漿料分佈器排出的漿料具有與常規進料斗相比大約20%的每單位寬度動量。 With a 6 inch wide and 2 inch thick conventional feed hopper outlet, the average speed of the outlet for a large volume product can be about 761 ft/min. In embodiments where the slurry distributor configured in accordance with the principles of the present disclosure includes a distribution outlet having an opening that is 24 inches wide and 0.75 inches thick, the average speed can be about 550 ft/min. For both devices, the mass flow rate was the same at 3,437 lb/min. For both cases, the momentum (mass flow rate * average speed) of the slurry was ~2,618,000 and 1,891,000 lb for the conventional feed hopper and slurry distributor, respectively. Ft/min 2 . Dividing the corresponding calculated momentum by the width of the conventional feed hopper outlet and slurry distributor outlet, the momentum per unit width of the slurry discharged from the conventional feed hopper is 402,736 (lb.ft/min 2 ) / ( Crossing the width of the feed hopper) and the momentum per unit width of the slurry discharged from the slurry distributor configured in accordance with the principles of the present disclosure is 78,776 (lb. ft/min 2 ) / (cross the width of the slurry distributor) inch). In this case, the slurry discharged from the slurry distributor has a momentum per unit width of about 20% compared to a conventional feed hopper.

Embodiments of a slurry distributor configured in accordance with principles of the present disclosure may include an internal flow geometry that is adapted to The first and second streams produce a controlled shear effect on the first and second aqueous calcined gypsum slurry streams as they advance from the first and second feed inlets toward the distribution outlet through the slurry distributor.

By including flow geometry features in the slurry distributor that are adapted to increase the degree of flow around the boundary wall layer, the tendency of the slurry to recirculate and/or stop flow and solidify therein in the slurry distributor is reduced. Therefore, as a result, it is possible to reduce the accumulation of the solidified slurry in the slurry distributor.

在該實施例中且參照圖65，在第二饋送入口325的第一位置L1和分佈出口330的半部1207的第十六個位置 L16之間的十六個不同位置L1-16處評估漿料分佈器的半部1205的特定幾何結構。每個位置L1-16表示如對應線所表示的漿料分佈器的半部1205的剖面切片。沿著每個剖面切片的幾何結構中心的流動線路1212用於確定相鄰位置L1-16之間的距離。第十一個位置L11對應於分佈導管328的進入部352的半部1214，其對應於饋送導管320的半部1207的第二饋送出口345的開口342。因此，第一個至第十個位置L1-10是在饋送導管320的半部1207中取得的，並且第十一個至第十六個位置是在分佈導管328的半部1209中取得的。 In this embodiment and with reference to Fig. 65, sixteen different positions L 1-16 between the first position L 1 of the second feed inlet 325 and the sixteenth position L 16 of the half 1207 of the distribution outlet 330 The particular geometry of the half 1205 of the slurry distributor is evaluated. Each position L 1-16 represents a cross-sectional slice of the half 1205 of the slurry distributor as indicated by the corresponding line. Flow lines 1212 along the center of the geometry of each section slice are used to determine the distance between adjacent locations L 1-16 . The eleventh position L 11 corresponds to the half 1214 of the inlet portion 352 of the distribution conduit 328 that corresponds to the opening 342 of the second feed outlet 345 of the half 1207 of the feed conduit 320. Thus, the first through tenth positions L 1-10 are taken in the half 1207 of the feed conduit 320, and the eleventh through sixteenth positions are taken in the half 1209 of the distribution conduit 328. .
對於每個位置L1-16，確定下面的幾何結構值：在第二饋送入口325和特定位置L1-16之間沿流動線路1212的距離；開口在位置L1-16處的截面積；位置L1-16的周長；以及位置L1-16的液力直徑。液力直徑是利用下面的公式計算的：Dhyd=4×A/P (方程式1) For each position L 1-16 , the following geometry values are determined: the distance along the flow line 1212 between the second feed inlet 325 and the particular position L 1-16 ; the cross-sectional area of the opening at the position L 1-16 ; L circumference positions 1-16; and L positions hydraulic diameter of 1-16. The hydraulic diameter is calculated using the following formula: D hyd = 4 × A / P (Equation 1)
其中Dhyd為液力直徑，A為特定位置L1-16的面積，以及P為特定位置L1-16的周長。 Where D hyd is the hydraulic diameter, A is the area of the specific position L 1-16 , and P is the circumference of the specific position L 1-16 .
利用入口條件，能夠確定每個位置L1-16的無因次值以描述內部流動幾何結構，如表1所示。曲線擬合方程式用於描述圖66中的漿料分佈器的半部1205的無因次幾何結構，圖66示出了距入口的無因次距離對無因次面積和液力直徑。 Using the inlet conditions, the dimensionless value of each position L 1-16 can be determined to describe the internal flow geometry, as shown in Table 1. The curve fitting equation is used to describe the dimensionless geometry of the half 1205 of the slurry distributor in Figure 66, and Figure 66 shows the dimensionless distance from the inlet to the dimensionless area and the hydraulic diameter.
對於每個位置L1-16的無因次值的分析表明，截面流面積從第二饋送入口325處的第一個位置L1到進入部352的半部1214(也是第二饋送出口345的開口342)處的第 十一個位置L11增加。在示例性實施方案中，在進入部352的半部1214處的截面流面積比第二饋送入口325處的截面流面積大近似1/3。在第一個位置L1和第十一個位置L11之間，第二進入段337和第二定形管道339的截面流面積在位置與位置L1-11間變化著。在該區域中，至少兩個相鄰位置L6、L7被構形為使得位置距第二饋送入口325更遠的位置L7具有比更靠近第二饋送入口325的相鄰位置L6更小的截面流面積。 Analysis of the dimensionless value for each position L 1-16 indicates that the cross-sectional flow area is from the first position L 1 at the second feed inlet 325 to the half 1214 of the entry portion 352 (also the second feed outlet 345) The eleventh position L 11 at the opening 342) is increased. In an exemplary embodiment, the cross-sectional flow area at the half 1214 of the inlet portion 352 is approximately 1/3 greater than the cross-sectional flow area at the second feed inlet 325. Between the first position L 1 and the eleventh position L 11 , the cross-sectional flow area of the second inlet section 337 and the second shaped duct 339 varies between position and position L 1-11 . In this region, at least two adjacent positions L 6 , L 7 are configured such that the position L 7 further away from the second feed inlet 325 has a more adjacent position L 6 closer to the second feed inlet 325 Small cross-sectional flow area.

在該實施例中，圖72的漿料分佈器2020用於對在饋送導管2022的球狀部2120的其中之一處的石膏漿料流進行建模。參照圖72，漿料分佈器2020的第一和第二進入段2036、2037各自具有直徑D。漿料分佈器2020具有沿縱軸線的長度，其為大約12×D。漿料分佈器2020大致沿機器方向2192延伸的中央縱軸線50對稱。漿料分佈器2020能夠被分成兩個半部2004、2005，兩個半部基本上關於中央縱軸線對稱。 In this embodiment, the slurry distributor 2020 of FIG. 72 is used to model the flow of gypsum slurry at one of the bulbs 2120 of the feed conduit 2022. Referring to Figure 72, the first and second inlet sections 2036, 2037 of the slurry distributor 2020 each have a diameter D. Slurry distributor 2020 has a length along the longitudinal axis that is approximately 12 x D. The slurry distributor 2020 is generally symmetrical about a central longitudinal axis 50 that extends in the machine direction 2192. The slurry distributor 2020 can be divided into two halves 2004, 2005, the two halves being substantially symmetrical about the central longitudinal axis.
參照圖73，圖72的漿料分佈器的半部2004用於對在除了使用不同的無因次黏度運算式之外與實施例2中相似的流動條件下通過其中的石膏漿料流進行建模。入口直徑D(x*=x/D)被選為長度尺度以將位置向量x(x*=x/D)非因次化，並且平均入口速度(U)用作速度尺度以將速度向量u(u*=u/U)非因次化。流動條件在其他方面與實施例2中的相似。 Referring to Figure 73, the half portion 2004 of the slurry distributor of Figure 72 is used to construct a gypsum slurry stream therethrough under flow conditions similar to those in Example 2 except using different dimensionless viscosity equations. mold. The inlet diameter D (x*=x/D) is selected as the length scale to delocalize the position vector x(x*=x/D), and the average inlet velocity (U) is used as the velocity scale to the velocity vector u (u*=u/U) is not factorized. The flow conditions are otherwise similar to those in Example 2.
參照圖73-76，使用有限體積法的計算流體動力學(CFD)技術用於確定分佈器的半部中的流動特性。特別地，計算來自區域A中不同垂直位置上的平均速度。對區域A中從進入段的中心延伸大約0.75D的區域進行分析。對十二個徑向間隔的垂直切片進行分析以計算球狀部徑向周圍的十二個不同的平均漿料速度。十二個位置基本上徑向間隔開以使各相鄰徑向位置分開大約30°。參照圖75和圖76，徑向位置1對應於與機器方向2192成相反關係的方向，並且徑向位置7對應於機器方向2192。徑向位置4和10與橫軸線60基本 上對準。 Referring to Figures 73-76, a computational fluid dynamics (CFD) technique using a finite volume method is used to determine flow characteristics in the half of the distributor. In particular, the average velocity from different vertical positions in region A is calculated. An analysis is performed for the region in the region A that extends from the center of the entry segment by about 0.75D. Twelve radially spaced vertical slices were analyzed to calculate twelve different average slurry velocities around the radial direction of the spheroid. The twelve positions are substantially radially spaced apart to separate each adjacent radial position by approximately 30°. Referring to Figures 75 and 76, radial position 1 corresponds to a direction that is inversely related to machine direction 2192, and radial position 7 corresponds to machine direction 2192. Radial positions 4 and 10 and horizontal axis 60 are basic Aligned on.
CFD技術與兩種不同的入口速度條件一起使用，u1=U和u2=1.5U。CFD分析的結果見於表IV中。速度大小被表達為無因次絕對值(|u|*=|u|/U)。在圖77中還對資料進行了繪圖。應當理解的是，漿料分佈器2020的其他半部2005將呈現出相似的流動特性。 CFD technology is used with two different inlet speed conditions, u1=U and u2=1.5U. The results of the CFD analysis are shown in Table IV. The magnitude of the velocity is expressed as a dimensionless absolute value (|u|*=|u|/U). The data is also plotted in Figure 77. It should be understood that the other halves 2005 of the slurry distributor 2020 will exhibit similar flow characteristics.
對於兩個流動條件，在各徑向位置1-12處的平均速度小於入口速度，但是大於零。範圍從入口速度的大約一半到入口速度的大約7/8(u*~入口速度的0.48至0.83)。球狀部中的輪廓凸形微凹表面有助於沿所有方向徑向向外重新引導來自進入段的流。 For both flow conditions, the average velocity at each radial position 1-12 is less than the inlet velocity, but greater than zero. The range is from about half of the inlet speed to about 7/8 of the inlet speed (u*~0.48 to 0.83 of the inlet speed). The contoured convex micro-concave surface in the ball helps to redirect the flow from the incoming section radially outward in all directions.
漿料速度還相對於入口速度放緩。對於既定流動條件，全部十二個徑向位置的平均速度基本相似(入口速度的~0.65或65%)。 The slurry speed is also slowed relative to the inlet speed. For a given flow condition, the average velocity of all twelve radial positions is substantially similar (~0.65 or 65% of the inlet velocity).
而且，在各流動條件下，在徑向位置3-5和9-11處出現了最高平均速度。沿著橫軸線或者沿著橫越機器方向60的較高的平均速度有助於向橫向側壁提供更多的邊緣流。 Moreover, under each flow condition, the highest average velocity occurs at radial positions 3-5 and 9-11. A higher average velocity along the transverse axis or along the cross machine direction 60 helps provide more edge flow to the lateral sidewalls.
因此，該實施例示出了，球狀部2120有助於放緩漿料並且將漿料的方向從向下垂直的方向改變成徑向向外水平面。此外，球狀部2120有助於將漿料流轉向到漿料分佈器2020的半部2004的定形管道的橫向內外側壁，以促進沿橫越機器方向60的漿料移動。 Thus, this embodiment shows that the bulb 2120 helps to slow the slurry and change the direction of the slurry from a downward vertical direction to a radially outward horizontal plane. In addition, the bulb 2120 facilitates diverting the slurry stream to the lateral inner and outer sidewalls of the shaped conduit of the half portion 2004 of the slurry distributor 2020 to facilitate slurry movement in the cross machine direction 60.
在該實施例中，圖72的漿料分佈器2020用於對在饋送導管2022的定形管道2041的其中之一處的石膏漿料流進行建模。參照圖78，圖72的漿料分佈器2020的半部2004用於對在除了使用與實施例4相似的無因次速度表達之外與實施例2相似的流動條件下通過其中的石膏漿料流進行建 模。特別地，對在定形管道的橫向內外壁處的漿料的旋渦運動進行分析。 In this embodiment, the slurry distributor 2020 of FIG. 72 is used to model the flow of gypsum slurry at one of the shaped conduits 2041 of the feed conduit 2022. Referring to Fig. 78, the half portion 2004 of the slurry distributor 2020 of Fig. 72 is used to pass the gypsum slurry therethrough under flow conditions similar to that of Example 2 except that the dimensionless velocity expression similar to that of Example 4 is used. Flow construction mold. In particular, the vortex motion of the slurry at the lateral inner and outer walls of the shaped pipe is analyzed.
參照圖73、圖74和圖78，使用有限體積法的計算流體動力學(CFD)技術用於確定分佈器2020的半部2004中的流動特性。特別地，對在定形管道2041的橫向內外側壁附近的漿料的旋渦運動進行分析。參照圖73，在漿料進入定形管道2041時，漿料以旋渦方式移動。隨著漿料沿機器方向2192向分佈出口2030移動，漿料流線型變得更加有序。如圖74和圖78中所示，在定形管道2041的在區域B1和B2中的大約1-3/4 D(1.72D)的縱向位置處區域中對漿料的旋渦運動進行分析。 Referring to Figures 73, 74, and 78, a computational fluid dynamics (CFD) technique using a finite volume method is used to determine flow characteristics in the half 2004 of the distributor 2020. In particular, the vortex motion of the slurry near the lateral inner and outer sidewalls of the shaped conduit 2041 is analyzed. Referring to Figure 73, as the slurry enters the shaped conduit 2041, the slurry moves in a vortex. As the slurry moves in the machine direction 2192 toward the distribution outlet 2030, the slurry streamline becomes more orderly. As shown in FIGS. 74 and 78, the vortex motion of the slurry is analyzed in the region of the shaped pipe 2041 at a longitudinal position of about 1-3/4 D (1.72 D) in the regions B1 and B2.
漿料的旋渦運動為其切向速度及其軸向(或機器方向)速度的函數。參照圖78，用於旋渦流的旋渦程度通常利用以下公式由旋渦數(S)表徵為角通量和線性動量：
並且r表示徑向位置。 And r represents the radial position.
如果在方程式5中使用切向速度和軸向速度的平均值，則其變成：
CFD技術與兩種不同的無因次入口速度條件一起使用，u1=U且u2=1.5U。CFD分析的結果見於表V中。應當理解的是，漿料分佈器的另一半部將呈現出相似的流動特性。通過該分析，已經發現，在實施方案中，漿料分佈器能夠被構形為產生在從大約零至大約10的範圍內的旋渦運動S m 以及在從大約零度至大約84°的範圍內的旋渦角。 The CFD technique is used with two different dimensionless inlet velocity conditions, u 1 =U and u 2 =1.5U. The results of the CFD analysis are shown in Table V. It should be understood that the other half of the slurry distributor will exhibit similar flow characteristics. By this analysis, it has been found, in the embodiments, the slurry distributor can be configured to generate in a range from about zero to about 10, and the swirl motion S m is in the range of from about zero to about 84 ° of Vortex angle.
對於兩個流動條件，在邊緣處的最大切向速度為在定形管道的進入部的邊緣區域中的入口速度的至少約一半。期望在橫向側壁附近的旋渦運動有助於在使用的同時保持漿料分佈器的內部幾何結構的清潔性。如圖73所示，漿料的旋渦運動在向分佈出口2030流動的方向上沿機器軸線50減弱。 For both flow conditions, the maximum tangential velocity at the edge is at least about half of the inlet velocity in the edge region of the entry portion of the shaped conduit. It is desirable that the vortex motion near the lateral sidewalls helps maintain the cleanliness of the internal geometry of the slurry distributor while in use. As shown in FIG. 73, the swirling motion of the slurry is attenuated along the machine axis 50 in the direction of flow to the distribution outlet 2030.
在該實施例中，圖72的漿料分佈器2020用於對通過饋送導管2022和分佈導管2028的石膏漿料流進行建模。參照圖73和圖74，圖72的漿料分佈器2020的半部2004用於對在除了使用與實施例4相似的無因次速度表達之外與實施例2中相似的流動條件下通過其中的石膏漿料流進行建模。 In this embodiment, the slurry distributor 2020 of FIG. 72 is used to model the gypsum slurry flow through the feed conduit 2022 and the distribution conduit 2028. Referring to Figures 73 and 74, the half 2004 of the slurry distributor 2020 of Figure 72 is used to pass through a flow condition similar to that in Example 2 except for the use of the dimensionless velocity expression similar to that of Example 4. The gypsum slurry stream is modeled.
對於所有的流動條件，含水石膏漿料的密度(ρ)被設定為1,000kg/m3，並且黏度因數K被設定為50。而且，對於進入B和1.5B的饋送入口2024中的石膏漿料的無因次饋送速度兩者，來評估流的特性。在表達為入口直徑D的函數的沿機器方向2192在定形管道2041的進入部下游的各連續無因次位置處確定以下流動特性：面積加權平均速度(U)， 面積加權平均剪切速率()，利用冪律模型(方程式2)計算的黏度，以及雷諾數(Re)(方程式4)。在沿縱軸線50的所提到的連續無因次位置處還計算液力直徑(方程式1)。利用入口流動條件，如表VI中所示，確定各位置的流動特性的無因次值。 The density (ρ) of the aqueous gypsum slurry was set to 1,000 kg/m 3 for all the flow conditions, and the viscosity factor K was set to 50. Moreover, the characteristics of the flow are evaluated for both the dimensionless feed speeds of the gypsum slurry entering the feed inlets 2024 of B and 1.5B. The following flow characteristics are determined at each successive dimensionless position downstream of the entry portion of the shaped conduit 2041 in the machine direction 2192 as a function of the inlet diameter D: area weighted average velocity (U), area weighted average shear rate ( ), the viscosity calculated using the power law model (Equation 2), and the Reynolds number (Re) (Equation 4). The hydraulic diameter (Equation 1) is also calculated at the mentioned continuous dimensionless position along the longitudinal axis 50. Using the inlet flow conditions, as shown in Table VI, the dimensionless values of the flow characteristics at each location were determined.
圖79-82為對於實施例6的不同流動條件計算出的流動特性的曲線圖。曲線擬合方程式用於描述在從饋送入口到分佈出口2030的半部2004之間的距離內流動特性的變化。因此，實施例表明了流動特性相對於入口速度的變化是一致的。 Figures 79-82 are graphs of flow characteristics calculated for different flow conditions of Example 6. The curve fitting equation is used to describe the change in flow characteristics over the distance between the feed inlet 20 and the half 2004 of the distribution outlet 2030. Thus, the examples show that the flow characteristics are consistent with changes in inlet velocity.
對於兩個流動條件，平均速度從饋送導管中的第一個位置(大約3D)到分佈導管2028的分佈出口2030的半部2117處的最後位置(大約12D)減小。平均速度基本上隨著漿料沿機器方向2192移動而逐漸地減小。在圖示的實施方案中，平均速度自入口速度減小了大約1/3，如圖79中所示。 For both flow conditions, the average speed decreases from the first position in the feed conduit (about 3D) to the last position (about 12D) at the half 2117 of the distribution outlet 2030 of the distribution conduit 2028. The average speed is substantially reduced as the slurry moves in the machine direction 2192. In the illustrated embodiment, the average speed is reduced by approximately 1/3 from the inlet velocity, as shown in FIG.
對於兩個流動條件，剪切速率從饋送導管中的第一個位置(大約3D)到分佈導管2028的分佈出口2030的半部2117處的最後位置(大約12D)增加。剪切速率從一個位置到另一個位置是變化的。在圖示的實施方案中，剪切速率在分佈導管2028的分佈出口2030的半部2117處相對於入口處增加，如圖80中所示。 For both flow conditions, the shear rate increases from the first position in the feed conduit (about 3D) to the last position (about 12D) at the half 2117 of the distribution outlet 2030 of the distribution conduit 2028. The shear rate varies from one location to another. In the illustrated embodiment, the shear rate increases relative to the inlet at the half 2117 of the distribution outlet 2030 of the distribution conduit 2028, as shown in FIG.
對於兩個流動條件，計算黏度從饋送導管中的第一個位置(大約3D)到分佈導管2028的分佈出口2030的半部2117處的最後位置(大約12D)減小。計算黏度從一個位 置到另一個位置是變化的。在圖示的實施方案中，計算黏度在分佈導管2028的分佈出口2030的半部2117處相對於入口處減小，如圖81中所示。 For both flow conditions, the calculated viscosity decreases from the first position in the feed conduit (about 3D) to the last position (about 12D) at the half 2117 of the distribution outlet 2030 of the distribution conduit 2028. Calculate viscosity from one bit Setting it to another location is a change. In the illustrated embodiment, the calculated viscosity decreases at the half 2117 of the distribution outlet 2030 of the distribution conduit 2028 relative to the inlet, as shown in FIG.
對於兩個流動條件，在圖82中雷諾數從饋送導管中的第一個位置(大約3D)到分佈導管2028的分佈出口2030的半部2117處的最後位置(大約12D)減小。在圖示的實施方案中，雷諾數在分佈導管2028的分佈出口2030的半部2117處相對於入口處減小了大約1/2。對於兩個流動條件，在分佈導管2028的分佈出口2030的半部2117處的雷諾數在層流區中。 For both flow conditions, the Reynolds number is reduced from the first position in the feed conduit (about 3D) to the last position (about 12D) at the half 2117 of the distribution outlet 2030 of the distribution conduit 2028 in FIG. In the illustrated embodiment, the Reynolds number is reduced by about 1/2 relative to the inlet at the half 2117 of the distribution outlet 2030 of the distribution conduit 2028. For both flow conditions, the Reynolds number at the half 2117 of the distribution outlet 2030 of the distribution conduit 2028 is in the laminar flow zone.
因此，已經發現，漿料分佈器的遠側半部(在大約6D和大約12D之間)被構形為提供穩流區，在該穩流區中，漿料的平均速度和雷諾數大致穩定且相對於饋送入口條件減小。如圖73中所示。漿料沿機器方向2192以大致流線型模式移動通過該穩流區。 Thus, it has been found that the distal half of the slurry distributor (between about 6D and about 12D) is configured to provide a steady flow zone in which the average velocity and Reynolds number of the slurry are substantially stable. And the condition is reduced with respect to the feed inlet. As shown in Figure 73. The slurry moves through the steady flow zone in a generally streamlined mode in the machine direction 2192.
在該實施例中，圖72的漿料分佈器2020用於對分佈導管2028的分佈出口2030處的石膏漿料流進行建模。在該實施例中，圖73的漿料分佈器的半部2004用於對在除了使用出口開口2081的寬度的無因次表達之外與實施例2中相似的流動條件下通過其中的石膏漿料流進行建模。橫過分佈出口2030的出口開口2081的半部2119的無因次寬度(w/W)(中心線在橫向中央中點2187處，如圖72所示等於零)。在其他方面，流動條件與實施例2中的相似。 In this embodiment, the slurry distributor 2020 of FIG. 72 is used to model the gypsum slurry flow at the distribution outlet 2030 of the distribution conduit 2028. In this embodiment, the half portion 2004 of the slurry distributor of FIG. 73 is used to pass the gypsum slurry therein under flow conditions similar to those in Example 2 except for the dimensionless expression of the width of the outlet opening 2081. The stream is modeled. The dimensionless width (w/W) of the half 2119 of the outlet opening 2081 across the distribution outlet 2030 (the centerline is at the midpoint of the lateral center 2187, equal to zero as shown in Figure 72). In other respects, the flow conditions are similar to those in Example 2.
使用有限體積法的CFD技術用於確定分佈器2020的半部2004中的流動特徵。特別地，對在橫過分佈出口2030的出口開口2081的半部2119的寬度的各位置處從出口開口2081排出的漿料的散佈角進行分析。利用以下公式來確定散佈角：散佈角=tan-1(Vx/Vz), (方程式9) The CFD technique using the finite volume method is used to determine the flow characteristics in the half 2004 of the distributor 2020. In particular, the spread angle of the slurry discharged from the outlet opening 2081 at various positions across the width of the half 2119 of the outlet opening 2081 of the distribution outlet 2030 is analyzed. Use the following formula to determine the scatter angle: scatter angle = tan -1 (V x /V z ), (Equation 9)
其中Vx為沿橫越機器方向的平均速度，以及Vz為沿機器方向的平均速度。 Where V x is the average speed in the cross machine direction and V z is the average speed in the machine direction.
對於如下兩種不同的條件來計算散佈角：一個為成形機構不壓縮出口開口2081(“無仿形”)，並且一個為成形機構壓縮出口開口2018(“有仿形”)。在模型化的漿料分佈器2020中，對於每個半部2004、2005，出口開口2018具有橫過其近似十英寸的總寬度的大約3/4英寸的高度，對於出口開口2081的總寬度，具有共二十英寸的高度。模型化的成形機構具有成形部件，該成形部件為大約15英寸寬且與橫向中央中點對準以使分佈出口的橫向部分與成形部件成偏置關係且不被壓縮。在模型化的“有仿形”條件下，成形機構壓縮出口開口大約1/8英寸以使得在成形部件下面的區域中出口開口為大約5/8英寸。確定對於兩種條件的散佈角，如表VII中所示。 The spread angle is calculated for two different conditions: one for the forming mechanism without compressing the outlet opening 2081 ("no profile"), and one for the forming mechanism compressing the outlet opening 2018 ("having a profile"). In the modeled slurry distributor 2020, for each half 2004, 2005, the outlet opening 2018 has a height that is about 3/4 of an inch across its total width of approximately ten inches, for the total width of the outlet opening 2081, It has a total height of twenty inches. The modeled forming mechanism has a forming member that is approximately 15 inches wide and aligned with the lateral center midpoint such that the lateral portion of the distribution outlet is offset from the forming member and is not compressed. Under modeled "fractal" conditions, the forming mechanism compresses the outlet opening by approximately 1/8 inch such that the outlet opening is approximately 5/8 of an inch in the area below the shaped part. The spread angle for both conditions was determined as shown in Table VII.
在兩種條件下，隨著位置自橫向中央中點2187(寬度=0)進一步向外移動，散佈角增加。在出口開口2081的橫向邊緣處散佈角最大。 Under both conditions, the spread angle increases as the position moves further outward from the lateral center midpoint 2187 (width = 0). The spread angle is greatest at the lateral edges of the outlet opening 2081.
利用成形機構來增加散佈角以壓縮排放出口 2030，從而降低出口開口2081的高度。在模型化的“有仿形”條件下，在橫向邊緣(寬度=0.466)處的最大散佈角相對於“無仿形”條件增加多於百分之二十五。在“有仿形”條件下，平均散佈角相對於“無仿形”條件增加多於百分之五十。 Use a forming mechanism to increase the spread angle to compress the discharge outlet 2030, thereby reducing the height of the outlet opening 2081. Under the modeled "fractal" condition, the maximum spread angle at the lateral edge (width = 0.466) is increased by more than twenty-five percent relative to the "no-profiling" condition. Under "fractal" conditions, the average spread angle increases by more than fifty percent relative to the "no-profiling" condition.
