Description
本發明係關於一種中空纖維型過濾器及中空纖維型過濾器製造方法。 The present invention relates to a hollow fiber type filter and a hollow fiber type filter manufacturing method.
舉例而言，傳統具備中空纖維束之中空纖維型過濾器，其具備機殼本體、置入機殼本體內之中空纖維束及各別安裝於機殼本體二端部且具備流體導出入口之蓋體元件，若於機殼本體各端部安裝蓋體元件，則存在於機殼本體與蓋體元件之間係安裝有封環。 For example, a hollow fiber type filter having a hollow fiber bundle is provided with a casing body, a hollow fiber bundle inserted into the casing body, and a cover each having a fluid outlet inlet attached to both ends of the casing body. In the body element, when the cover member is attached to each end of the casing body, a seal ring is installed between the casing body and the cover member.
舉例而言，專利文獻1中揭露有中空纖維裝置，其於機殼本體之包圍體中安裝有中空纖維束，並於設置於該包圍體內且固定中空纖維束各端部之橫向隔牆上設置至少一環狀溝槽，另於封閉包圍體各端部之外殼內面設置與該至少一環狀溝槽相卡合之至少一環狀凸肋，更於該溝槽與該凸肋間形成之空隙內配置含樹脂系材料之封膠。 For example, Patent Document 1 discloses a hollow fiber device in which a hollow fiber bundle is mounted in a surrounding body of a casing body, and is disposed on a lateral partition wall provided in the surrounding body and fixed at each end of the hollow fiber bundle. Forming at least one annular groove, and at least one annular rib engaged with the at least one annular groove on the inner surface of the outer casing of each end of the enclosed enclosure, and forming a space between the groove and the rib A sealant containing a resin-based material is disposed in the void.
而未使用上述封環之方法中，以超音波熔接機殼本體與蓋體元件之方法較為廣泛應用。舉例而言，利用超音波熔接法將樹脂製機殼本體端部與樹脂製蓋體元件互相加壓抵觸，並於該抵觸面施加超音波，藉此將熔融之樹脂互相結合，以接合機殼本體與蓋體元件。 In the method in which the above-mentioned sealing ring is not used, the method of ultrasonically welding the casing body and the cover member is widely used. For example, the resin case body end portion and the resin cap member are pressed against each other by ultrasonic welding, and ultrasonic waves are applied to the contact surface, thereby bonding the molten resin to each other to bond the case. Body and cover components.
但使用超音波熔接法之密封法，其機殼本體端部所形成之密封區係位於中空纖維束切口端面之非常外圍側，其 中，該中空纖維束切口端面係以封膠固定於機殼本體上。結果係於中空纖維束切口端面外圍區形成一空間，而該空間係有產生殘留液之虞慮。 However, in the sealing method using the ultrasonic welding method, the sealing portion formed at the end portion of the casing body is located on the very peripheral side of the end face of the slit of the hollow fiber bundle, The hollow fiber bundle cut end face is fixed to the casing body by a sealant. As a result, a space is formed in the peripheral portion of the end face of the hollow fiber bundle cut, and this space has a concern of generating residual liquid.
因此，為了將機殼本體與蓋體元件進行液密，專利文獻2中揭露，於機殼本體一端開口部安裝蓋體元件，其中，該機殼本體一端開口部係以封膠將中空纖維束固定於機殼本體一端開口部，以具備中空纖維束切口端面，而該蓋體元件內側面所設置之環狀溝槽內係填充有黏著劑，如此，以黏著劑將中空纖維束切口端面外圍區與蓋體元件進行環狀密封，其中，該中空纖維束切口端面係機殼本體端部面及/或封膠所形成之密封部端面。 Therefore, in order to liquid-tighten the casing body and the cover member, Patent Document 2 discloses that a cover member is attached to an opening at one end of the casing body, wherein the open end of the casing body is sealed with a hollow fiber bundle. The end portion of the casing body is fixed to the end portion of the casing body to have a hollow fiber bundle cutting end surface, and the annular groove provided on the inner side surface of the cover member is filled with an adhesive, so that the end of the hollow fiber bundle is cut with an adhesive. The zone and the cover member are annularly sealed, wherein the hollow fiber bundle cut end face is an end face of the casing body and/or an end face of the seal formed by the sealant.

[專利文獻2]日本發明專利第2936456號說明書 [Patent Document 2] Japanese Invention Patent No. 2936456
舉例而言，若將中空纖維型過濾器做為裝設於人工腎臟透析裝置上之透析液過濾器使用，則因大量透析液通過中空纖維型過濾器內，而提高中空纖維型過濾器的內壓，結果導致設置有導出入口之蓋體元件及機殼本體、蓋體元件間之一密封區產生壓力負荷。而且，若中空纖維型過濾器的內壓過度上升，則蓋體元件或密封區係容易產生破損。 For example, if the hollow fiber type filter is used as a dialysate filter installed on an artificial kidney dialysis device, the inside of the hollow fiber type filter is improved because a large amount of dialysate passes through the hollow fiber type filter. As a result, a pressure load is generated in the sealing member provided between the cover member provided with the outlet and the casing body and the cover member. Further, when the internal pressure of the hollow fiber type filter is excessively increased, the lid member or the sealing portion is likely to be damaged.
有鑑於上述狀況而完成之本發明，係提供一種中空纖維型過濾器及中空纖維型過濾器製造方法，其減少密封區與中空纖維束切口端面區所形成之空隙，其中，該密封區係形成於機殼本體端部，而該中空纖維束切口端面區係以封膠固定於機殼本體上，並縮減蓋體元件所受之受壓面積，同時提高機殼本體端部與蓋體元件端部之密封抗壓強度。 The present invention has been made in view of the above circumstances, and provides a hollow fiber type filter and a hollow fiber type filter manufacturing method which reduce a gap formed between a sealing portion and a slit region of a hollow fiber bundle, wherein the sealing portion is formed At the end of the casing body, the hollow fiber bundle cut end face region is fixed on the casing body with a sealant, and reduces the pressure receiving area of the cover body component, and at the same time increases the casing body end portion and the cover body end portion.

The continuous extending film adheres continuously to the inner surface of the cover member, thereby changing the shape of the cover member as the internal pressure fluctuates during filtration, and the continuous outer film can be changed, so that the continuous outer film can be The function of the adhesive reinforcing portion is exerted, and the compressive strength of the cover member is improved.
第1圖係本實施態樣中空纖維型過濾器100的結構一實施例示意圖。中空纖維型過濾器100係具備：中空纖維束30；機殼本體20，其透過第一封膠所形成之第一密封部24將中空纖維束30固定於機殼本體用筒體22之至少一端開口部上，以具備中空纖維束30切口端面；蓋體元件10，其各別安裝於機殼本體20二端部且具備流體導出入口12；及由填充部與連續外膜所組成之第二密封部40，其中，該填充部係於中空纖維束30切口端面外圍區與機殼本體20端部、蓋體元件10端部的連結區之間所形成之一空間內填充有第二封膠，而連續外膜係自填充部延伸至蓋體元件內面至少一局部且附著於蓋體元件內面。 Fig. 1 is a schematic view showing an embodiment of the structure of the hollow fiber type filter 100 of the present embodiment. The hollow fiber type filter 100 includes a hollow fiber bundle 30, and a casing body 20 that fixes the hollow fiber bundle 30 to at least one end of the casing body 22 through the first sealing portion 24 formed by the first sealant. The opening portion is provided with a slit end face of the hollow fiber bundle 30; the cover member 10 is separately attached to both ends of the casing body 20 and has a fluid outlet inlet 12; and a second portion composed of a filling portion and a continuous outer film a sealing portion 40, wherein the filling portion is filled with a second sealant in a space formed between a peripheral portion of the slit end face of the hollow fiber bundle 30 and an end portion of the casing body 20 and the end portion of the cover member 10. And the continuous outer film system extends from the filling portion to at least a portion of the inner surface of the cover member and adheres to the inner surface of the cover member.
接著，放大第1圖中以虛線圍住之X部分，填充該第二封膠前後之中空纖維束30切口端面外圍區與機殼本體20端部、蓋體元件10端部的連結區之間所形成之空間結構差異係於下方參照第2A圖及第2B圖進行說明。 Next, the X portion enclosed by a broken line in FIG. 1 is enlarged, and the peripheral portion of the slit end face of the hollow fiber bundle 30 before and after the second sealant is filled between the end portion of the casing body 20 and the joint portion of the end of the cover member 10. The spatial structure difference formed is described below with reference to FIGS. 2A and 2B.
如第2A圖所示，於填充第二封膠前，中空纖維束30切口端面外圍區與機殼本體用筒體22端部、蓋體元件10 端部的連結區之間形成有一空間。因此，如第4A圖所示，填充第二封膠前之蓋體元件所受之受壓面積，係由中空纖維束30切口端面面積與其外圍區面積所形成。 As shown in FIG. 2A, before the filling of the second sealant, the outer peripheral region of the slit end face of the hollow fiber bundle 30 and the end portion of the cylindrical body 22 for the casing body, the cover member 10 A space is formed between the joint areas of the ends. Therefore, as shown in Fig. 4A, the pressed area of the cover member before the filling of the second sealant is formed by the area of the end face of the hollow fiber bundle 30 and the area of its peripheral portion.
反之，如第2B圖所示，本實施態樣中形成有填充部42與連續外膜44所組成之第二密封部40，其中，填充部42係於該空間內填充第二封膠，而連續外膜44係自填充部42延伸至蓋體元件內面之至少一局部且附著於蓋體元件10內面，因此，蓋體元件所受之受壓面積僅為中空纖維束30切口端面面積。因蓋體元件10所受之受壓面積係較小，舉例而言，若將本實施態樣中空纖維型過濾器100作為透析液過濾器使用，即便透析液呈高流量，亦可降低蓋體元件所受之壓力，舉例而言，當透析裝置進行消毒時係流入約90℃之檸檬酸熱水，而透析時係流入約37℃之透析液，因此，於透析裝置中提供一種即便反覆施加熱負荷於透析裝置所設置之透析液過濾器上，或因複式幫浦脈動等反覆產生各種壓力變動時，亦具備充分強度之中空纖維型過濾器。另，於中空纖維束30切口端面外圍區(參照第2A圖)與機殼本體用筒體22端部、蓋體元件10端部的連結區之間所形成之一空間內形成填充有第二封膠之填充部42，藉此，以降低過濾時隨著機殼本體內壓上升而蓋體元件10所受之受壓面積。如此，以抑制蓋體元件因過度受壓而產生之變形或破損。另外，因形成有自填充部42延伸至蓋體元件10內面之至少一局部且附著於蓋體元件10內面之連續外膜44，即便過濾時因內壓變動而導致蓋體元件10形狀產 生變化，連續外膜44係可跟著彈性變化，結果連續外膜44係可發揮黏著補強之功用，以防止填充部42產生剝離，藉此，以提高蓋體元件10的抗壓強度，並可長時間維持中空纖維型過濾器的使用強度。 On the other hand, as shown in FIG. 2B, in this embodiment, a second sealing portion 40 composed of a filling portion 42 and a continuous outer film 44 is formed, wherein the filling portion 42 is filled with the second sealing material in the space. The continuous outer film 44 extends from the filling portion 42 to at least a portion of the inner surface of the cover member and adheres to the inner surface of the cover member 10. Therefore, the pressure receiving area of the cover member is only the end surface area of the slit of the hollow fiber bundle 30. . Since the pressure receiving area of the cover member 10 is small, for example, if the hollow fiber filter 100 of the present embodiment is used as a dialysate filter, the cover can be lowered even if the dialysate has a high flow rate. The pressure on the component, for example, is that when the dialysis device is sterilized, it flows into a hot water of citric acid at about 90 ° C, and when it is dialyzed, it flows into a dialysate of about 37 ° C. Therefore, it is provided in the dialysis device even if it is applied repeatedly. A hollow fiber type filter having sufficient strength is also provided when the heating load is applied to the dialysate filter provided in the dialysis apparatus or when various pressure fluctuations are repeatedly generated due to the pulsation of the duplex pump. Further, a space formed in a space formed between the peripheral end region of the slit end face of the hollow fiber bundle 30 (see FIG. 2A) and the end portion of the casing body 22 and the end portion of the cover member 10 is filled with a second space. The filling portion 42 of the sealant thereby reduces the pressure receiving area of the lid member 10 as the pressure in the casing body rises during filtration. In this way, deformation or breakage of the cover member due to excessive compression is suppressed. Further, since the continuous outer film 44 which extends from at least a part of the inner surface of the lid member 10 and adheres to the inner surface of the lid member 10 is formed, the shape of the lid member 10 is caused by the internal pressure fluctuation during filtration. Production The change of the continuous outer film 44 can be followed by the elastic change, and as a result, the continuous outer film 44 can exert the function of adhesion and reinforcement to prevent the filling portion 42 from being peeled off, thereby improving the compressive strength of the cover member 10, and The strength of use of the hollow fiber type filter is maintained for a long time.
本實施態樣中空纖維型過濾器的受壓面積降低率係配合中空纖維型過濾器內徑而有所差異，舉例而言，係為10%以上、50%以下。若低於該範圍下限，則對蓋體元件而言，受壓降低係不夠，且長時間於蓋體元件產生壓力負荷。另外，若超出該範圍上限，則有堵塞中空纖維束切口端面之虞慮，以致過濾器性能無法充分發揮。 The reduction rate of the pressure receiving area of the hollow fiber type filter according to the present embodiment differs depending on the inner diameter of the hollow fiber type filter, and is, for example, 10% or more and 50% or less. If it is less than the lower limit of the range, the pressure reduction of the cover member is insufficient, and a pressure load is generated on the cover member for a long period of time. Further, if the upper limit of the range is exceeded, there is a concern that the end face of the hollow fiber bundle is notched, so that the performance of the filter cannot be sufficiently exerted.
此外，本實施態樣之連續外膜44係於蓋體元件10內部面積為10%以上、100%以下被形成。於該範圍內係可發揮黏著補強之功用，以防止填充部42產生剝離。 Further, the continuous outer film 44 of the present embodiment is formed such that the inner area of the lid member 10 is 10% or more and 100% or less. Within this range, the function of adhesion and reinforcement can be exerted to prevent peeling of the filling portion 42.
此外，該連續外膜44之厚度，舉例而言，係為30μm以上、70μm以下。藉此，即便機殼本體內部壓力反覆產生變動，其亦能充分變化，並能長時間附著於蓋體元件10內面。再者，並未將連續外膜44厚度限定於30~70μm範圍內，亦可因應填充材之材質、種類而做適度變更。 Further, the thickness of the continuous outer film 44 is, for example, 30 μm or more and 70 μm or less. Thereby, even if the internal pressure of the casing body repeatedly changes, it can be sufficiently changed and can be attached to the inner surface of the lid member 10 for a long period of time. Further, the thickness of the continuous outer film 44 is not limited to the range of 30 to 70 μm, and may be appropriately changed depending on the material and type of the filler.

A curable resin composition such as an ester or an epoxy resin. In the first sealant of the present embodiment, from the viewpoint of self-sealing property and adhesiveness, it is preferred to use a two-liquid hardening type polyurethane or a room temperature hardening type liquid helium.
本實施態樣係將中空纖維束30置入於機殼本體用筒體22內，並於機殼本體用筒體22注入第一封膠(以下亦稱為「第一密封劑」)，當第一封膠硬化後，藉由硬化後之第一封膠及切割中空纖維束30端部以形成中空纖維束切口端面，如此，以分離出中空纖維內側流路及中空纖維外側流路。 In the present embodiment, the hollow fiber bundle 30 is placed in the casing body 22, and the first sealant (hereinafter also referred to as "first sealant") is injected into the casing body cylinder 22. After the first gel is hardened, the first sealant after hardening and the end of the hollow fiber bundle 30 are cut to form a hollow fiber bundle cut end face, thereby separating the hollow fiber inner flow path and the hollow fiber outer flow path.
形成第二密封部40之第二封膠，係與第一封膠相同之材料亦或是同類型之材料。藉此，第二密封部40不僅可牢固附著於機殼本體用筒體22，同時亦附著於蓋體元件10內面。 The second sealant forming the second sealing portion 40 is the same material as the first sealant or the same type of material. Thereby, the second sealing portion 40 can be firmly adhered not only to the casing body 22 but also to the inner surface of the lid member 10.
接著，參照第3圖至第5圖以說明本實施態樣之中空纖維型過濾器製造方法的一實施例。 Next, an embodiment of a method of manufacturing a hollow fiber type filter according to the present embodiment will be described with reference to Figs. 3 to 5.
本實施態樣之中空纖維型過濾器製造方法，係如第3圖所示，其具備：於機殼本體20二端部各別連結一對蓋體元件10端部之製程，其中，機殼本體20係透過第一封膠所形成之第一密封部24以將中空纖維束30固定於機殼本體用筒體22的至少一端開口部，以具備中空纖維束30切口端面；以機殼本體20中心軸為中心進行旋轉，並自蓋體元件10所具備之流體導出入口12沿著蓋體元件10內面導入第二封膠之製程。本說明書中所述之「機殼本體20中心軸」，係意謂第3圖所示之沿著機殼本體20長度方向延伸之中心線。 The manufacturing method of the hollow fiber type filter according to the present embodiment is as shown in FIG. 3, and includes a process of connecting the ends of the pair of cover members 10 at the two end portions of the casing body 20, wherein the casing The main body 20 is configured to pass through the first sealing portion 24 formed by the first sealant to fix the hollow fiber bundle 30 to at least one end opening portion of the casing body cylinder 22 to provide the hollow fiber bundle 30 slit end face; The center axis of the 20 is rotated, and a process of introducing the second sealant from the inner surface of the cover member 10 from the fluid outlet inlet 12 provided in the cover member 10. The "central axis of the casing body 20" described in the present specification means a center line extending along the longitudinal direction of the casing body 20 as shown in FIG.
更如第3圖、第4A圖所示，本實施態樣之另一中空纖維型過濾器製造方法，於導入該第二封膠之製程中，係將機殼本體20中心軸維持呈水平方向，並以機殼本體20中心軸為中心進行旋轉，且自蓋體元件10所具備之流體導出入口12沿著蓋體元件10內面導入第二封膠。 Further, as shown in FIG. 3 and FIG. 4A, another hollow fiber filter manufacturing method according to this embodiment maintains the central axis of the casing body 20 in a horizontal direction during the process of introducing the second sealing compound. And rotating around the central axis of the casing body 20, and the fluid discharge inlet 12 provided in the cover member 10 is introduced into the second seal along the inner surface of the cover member 10.
藉此，自流體導出入口12導入之第二封膠，係透過重力而沿著蓋體元件10內面移動，更以機殼本體20中心軸為中心進行旋轉，藉由離心力均勻地於中空纖維束30切口端面外圍區(參照第2A圖)與機殼本體用筒體22端部、蓋體元件10端部的連結區之間所形成之一空間內形成填充有第二封膠之第二密封部40。而第二密封部40係如第2B圖所示，係由該空間內填充有第二封膠之填充部42及自填充 部42延伸至蓋體元件內面至少一局部且附著於蓋體元件內面之連續外膜44所形成。因此，如第4B圖所示，透過第二密封部40，蓋體元件10所受之受壓面積僅為中空纖維束30切口端面面積，係降低蓋體元件10的受壓面積。更透過該製造方法形成自填充部42延伸至蓋體元件10內面至少一局部且附著於蓋體元件10內面之連續外膜44，藉此，即便過濾時(如：透析時)隨著內壓變動導致蓋體元件10形狀產生變化，連續外膜44亦可跟著彈性變化，結果連續外膜44係可發揮黏著補強之功用，以防止填充部42產生剝離，如此，以提高蓋體元件10的抗壓強度，並長時間維持中空纖維型過濾器的使用強度。 Thereby, the second sealant introduced from the fluid outlet inlet 12 is moved along the inner surface of the cover member 10 by gravity, and is rotated about the central axis of the casing body 20, and is uniformly distributed to the hollow fiber by centrifugal force. A second space filled with the second sealant is formed in a space formed between the peripheral portion of the end face of the bundle 30 (see FIG. 2A) and the end portion of the tubular body 22 and the end of the cover member 10 Sealing portion 40. The second sealing portion 40 is a filling portion 42 filled with a second sealing material and self-filling as shown in FIG. 2B. The portion 42 extends to a continuous outer film 44 that is at least partially internal to the cover member and that is attached to the inner surface of the cover member. Therefore, as shown in Fig. 4B, the pressure receiving area of the lid member 10 transmitted through the second sealing portion 40 is only the area of the end surface of the slit of the hollow fiber bundle 30, and the pressure receiving area of the lid member 10 is lowered. Further, the continuous outer film 44 extending from the filling portion 42 to at least a portion of the inner surface of the lid member 10 and adhering to the inner surface of the lid member 10 is formed by the manufacturing method, thereby allowing even filtration (for example, dialysis) The change of the internal pressure causes the shape of the cover member 10 to change, and the continuous outer film 44 can also change with the elasticity. As a result, the continuous outer film 44 can function as an adhesive reinforcement to prevent the filling portion 42 from being peeled off, thereby improving the cover member. The compressive strength of 10, and the strength of use of the hollow fiber type filter is maintained for a long time.
第3圖及第4A圖所示之製造方法，其以機殼本體中心軸為中心進行旋轉之次數，係配合機殼本體外徑或第二封膠材料而有所差異，舉例而言，係500rpm以上、2000rpm以下，若第二封膠為二液硬化型聚氨基甲酸酯，則較佳係800rpm以上、1500rpm以下。 In the manufacturing method shown in FIG. 3 and FIG. 4A, the number of rotations around the central axis of the casing body is different depending on the outer diameter of the casing body or the second sealing material, for example, 500 rpm or more and 2000 rpm or less, and if the second sealant is a two-liquid hardening type polyurethane, it is preferably 800 rpm or more and 1500 rpm or less.
此外，如第5圖所示，本實施態樣之另一中空纖維型過濾器製造方法，其於導入該第二封膠之製程中，係將機殼本體20中心軸維持呈垂直方向，並於蓋體元件10所具備之流體導出入口12安裝注入噴嘴60，該注入噴嘴60前端面係封閉且於前端部外側面形成有開口部，再以機殼本體20中心軸為中心進行旋轉，以藉由離心力將導入注入噴嘴60之第二封膠經由注入噴嘴60開口部62a、62b沿著蓋體元件10內面導入機殼本體用筒體22端部、蓋體元件10 端部的連結區與中空纖維束30切口端面外圍區之間。 In addition, as shown in FIG. 5, another hollow fiber type filter manufacturing method according to the embodiment, in which the central axis of the casing body 20 is maintained in a vertical direction during the process of introducing the second sealing material, An injection nozzle 60 is attached to the fluid outlet inlet 12 of the lid member 10, and the front end surface of the injection nozzle 60 is closed, and an opening is formed on the outer surface of the front end portion, and is rotated around the central axis of the casing body 20 to The second sealant introduced into the injection nozzle 60 is introduced into the end portion of the casing body 22 and the cover member 10 along the inner surface of the cover member 10 via the opening portions 62a and 62b of the injection nozzle 60 by centrifugal force. The joint portion of the end portion is between the peripheral portion of the slit end face of the hollow fiber bundle 30.
以機殼本體20中心軸為中心進行旋轉，藉此，將自注入噴嘴60導入之第二封膠透過離心力填充於中空纖維束30切口端面外圍區(參照第2A圖)與機殼本體用筒體22端部、蓋體元件10端部的連結區之間所形成之一空間內。因此，如以上所述，係如第4B圖所示，可降低蓋體元件10的受壓面積，另形成有延伸至蓋體元件10內面至少一局部且附著於蓋體元件10內面之連續外膜44(第2B圖)。藉此提高蓋體元件10的抗壓強度，並長時間維持中空纖維型過濾器的使用強度。 Rotating around the central axis of the casing body 20, the second sealant introduced from the injection nozzle 60 is filled in the peripheral region of the slit end face of the hollow fiber bundle 30 by centrifugal force (see FIG. 2A) and the casing body The space between the end of the body 22 and the connecting portion of the end of the cover member 10 is formed. Therefore, as described above, as shown in FIG. 4B, the pressure receiving area of the cover member 10 can be reduced, and at least a portion extending to the inner surface of the cover member 10 and attached to the inner surface of the cover member 10 can be formed. Continuous outer membrane 44 (Fig. 2B). Thereby, the compressive strength of the lid member 10 is increased, and the use strength of the hollow fiber type filter is maintained for a long period of time.
第5圖所示之製造方法中，為了不讓第二封膠於中空纖維束30切口端面產生擴散，較佳係適度選擇第二封膠的注入速度及旋轉次數。再者，為了方便製造，其旋轉次數較佳為上述相同的範圍內。 In the manufacturing method shown in Fig. 5, in order to prevent the second sealant from being diffused on the slit end faces of the hollow fiber bundle 30, it is preferable to appropriately select the injection speed and the number of rotations of the second sealant. Further, in order to facilitate the production, the number of rotations is preferably within the same range as described above.
此外，第3圖至第5圖所示之任一方法中，本實施態樣中空纖維型過濾器製造方法，其連結機殼本體端部與蓋體元件端部之製程更可使用超音波熔接法，係透過細微超音波振動與加壓力於該樹脂所組成之機殼本體端部與樹脂所組成之蓋體元件端部，將欲進行接合之二端部產生強力摩擦熱並熔融，以進行二端部接合。 In addition, in any of the methods shown in FIGS. 3 to 5, in the method for manufacturing a hollow fiber type filter according to the embodiment, the process of connecting the end portion of the casing body and the end portion of the cover member can be ultrasonically welded. In the method, the end portion of the casing body composed of the resin and the end portion of the cover member composed of the resin are subjected to fine ultrasonic vibration and pressure, and the two ends to be joined are strongly frictional heat and melted. The two ends are joined.
該超音波熔接法，更可***re-joint法、energy-direct-joint法或兩者之組合中加以選擇。本發明share-joint法係習知之超音波熔接法中連結接合部方法的一實施例，其連結方法之連結處係呈斜面之局部面狀抵 觸，且傾斜角度係與超音波振動方向相摩擦之運動角度。另，本發明energy-direct-joint法亦為習知之超音波熔接法中連結接合部方法的一實施例，其連結方法係將能量集中於稱為導向體(director)之三角形突起上，並透過反覆碰撞現象而發熱。 The ultrasonic welding method can be selected from a share-joint method, an energy-direct-joint method, or a combination of the two. The share-joint method of the present invention is an embodiment of the method for joining joints in the ultrasonic welding method of the prior art, wherein the joint of the joining method is a partial surface of the inclined surface Touch, and the tilt angle is the angle of motion that rubs against the direction of vibration of the ultrasonic wave. In addition, the energy-direct-joint method of the present invention is also an embodiment of the conventional method of joining joints in the ultrasonic welding method, wherein the joining method concentrates energy on a triangular protrusion called a director and transmits Repeated collision and fever.
此外，本實施態樣另一中空纖維型過濾器製造方法，其連結機殼本體端部與蓋體元件端部之製程中，亦可鎖合形成於機殼本體20外周面之外螺紋與形成於蓋體元件10內周面之內螺紋，以連結機殼本體端部與蓋體元件。機殼本體端部與蓋體元件之連結，更可將鎖合之連結與超音波熔接之熔融接合加以組合。 In addition, in another manufacturing method of the hollow fiber type filter according to the embodiment, in the process of connecting the end portion of the casing body and the end portion of the cover member, the thread may be formed on the outer peripheral surface of the casing body 20 and formed. The inner peripheral surface of the cover member 10 is internally threaded to connect the end of the casing body with the cover member. The connection between the end of the casing body and the cover member can be combined with the fusion bonding of the interlocking connection with the ultrasonic welding.
以下係利用實施例以說明本發明，但並未將本發明侷限於該等實施例中。 The following examples are presented to illustrate the invention but are not intended to limit the invention.
