Description

【０００１】
【発明の属する技術分野】
本発明は、植物繊維質素材や動物繊維質素材等の繊維質素材組織を膨張軟化破壊する装置に関する。
【０００２】
【従来の技術】
従来から、籾殻、鋸屑、樹木の外皮等の植物繊維質素材或いは羊毛屑、羽毛、皮革等の動物繊維質素材を家畜家禽の肥料、増量剤及び漁業用餌料等に使用するために、これらの繊維質素材の組織を膨張軟化破壊する装置が知られている。
【０００３】
ここで図３は従来装置の断面図であり、図３中の１は前端に排出用開口部１１が形成されると共に側面上に素材投入口１２が形成された概ね円筒形の装置本体である。
【０００４】
当該装置本体１の内部には、素材投入口１２から前方の排出用開口部１１に向けて縮径した、素材移送用のスクリュー羽根２１を取り付けた加工軸部が設けられている。この加工軸部２の後方側には軸方向に動力伝達軸部３が接続されている。この動力伝達部３は軸受け部である前方のラジアルベアリング６及び後方のスラストベアリング７によって支持されており、動力伝達軸後方で軸方向に接属されたプーリ２２が図外の動力源からの力をベルト等で伝達することで回転力を得る。
【０００５】
素材投入口１２とラジアルベアリング６との間には、装置本体１の内壁面を周方向に加工し、前後２ヶ所に全周に亘った溝が形成され、これらの溝に断面コ字型でリング状の弾性体によるシール部材４、５が夫々嵌め込まれている。後方に位置する第１のシール部材４は素材が潤滑油が封入された軸受け部周辺へと入り込むことを、又前方に位置する第２のシール部材５は封入された潤滑油が素材投入領域側へと流出することを、夫々防止している。又、スラストベアリング７の後方にも同様の構成によるシール部材８がリング状に嵌め込まれている。
【０００６】
そしてこのような従来装置によれば素材投入口１２から投入された繊維質素材を、回転軸２の回転によりスクリュー羽根２３が排出用開口部１１へ移送しつつ装置本体１の内壁面との間で加圧圧縮した後に切削し、その切削物を排出用開口部１１から排出する一連の工程により繊維質素材は膨張軟化破壊される。
【０００７】
【発明が解決しようとする課題】
しかしながらこのような従来装置においては、投入された繊維質素材の性状や投入領域の素材の滞留状態等によっては、スクリュー羽根２１の回転によって逆方向、つまり第２のシール部材５のコ字型部に素材が食い込み（図４（ａ）参照）、この状態で投入領域内の素材がスクリュー羽根２３の回転で更に後方へ押し付けられると、その押し付け力が既にコ字型部の前方に滞留している素材を通じてコ字型部へと伝達される。
【０００８】
一方シール部材５は弾性体の弾性力により気密性を保っているので、前述のコ字型部へ伝達された押し付け力により変形して図４（ｂ）のようにシール部材５と装置本体１の内壁面との間に隙間が形成され、この隙間をくぐって素材が軸受け側に入り込み、シールされていた潤滑油が加工軸部２側へと流出するおそれがあった。
【０００９】
本発明はこのような事情に基づいてなされたものであり、シール部材後方に封入されている潤滑油の漏れを確実に防止し、メンテナンス作業を軽減することにある。
【００１０】
【課題を解決するための手段】
本発明は、前端に排出用開口部が形成されると共に側面上に素材投入口が形成された概ね円筒状の装置本体と、
前記本体内に設けられ、素材投入口から前方の排出用開口部に向けて縮径したスクリュー羽根を有する加工軸部と、
前記前記素材投入口より後方側にて前記加工軸部に軸方向に接続され、装置本体内にて軸受けされた動力伝達軸部と、
前記動力伝達軸部と装置本体内との間に封入された動力伝達軸部の軸受け用の潤滑油と、
素材投入口から素材が投入される素材投入領域へ潤滑油が流出するのを防ぐために動力伝達軸部の外周に沿ってリング状に設けられた第１のシール部材と、
この第１のシール部材の前方側に、素材が第１のシール部材に接しないようにするために動力伝達軸部の外周に沿ってリング状に設けられた第２のシール部材と、を備え、
素材投入口より投入された繊維質素材をスクリュー羽根の回転により前方の排出用開口部へ移送しつつ、装置本体内壁と加工軸部との間で、加圧圧縮するようにした繊維質素材の組織破壊装置において、
素材投入領域の素材が第２のシール部材側へ向かうのを阻止するために、前記素材投入領域と第２のシール部材との間に、素材投入領域側から第２のシール部材側に向かって、全周に亘って動力伝達軸部の外周面に形成されたリング状の第１の突起と装置本体の内周面に形成されたリング状の第２の突起とをこの順に設け、
第１の突起は、外周面がわずかな隙間を介して装置本体の内周面に対向するように形成されると共に、第２のシール部側の端面が動力伝達軸部の外周面と直交するように形成され、
第２の突起は、素材投入領域側の端面が第１の突起における前記第２のシール部側の端面とわずかな隙間を介して対向するように形成されると共に、内周面がわずかな隙間を介して動力伝達軸部の外周面に対向するように形成され、
こうして第１の突起の外周面側の隙間、第１の突起と第２の突起との間の隙間及び第２の突起の内周面側の隙間により縦断側面で見たときにクランク状の隙間を形成し、
更に縦断側面で見たときに、第２の突起の素材投入領域側の端面において、第１の突起の外周面側の隙間の延長線上の部位が凹んでいることを特徴とする。
【００１２】
また、本発明は前記動力伝達軸部の回転停止時において、潤滑油の液面がシール部材以下のレベルになる程度に動力伝達軸部下方の装置本体内壁面を凹ませて潤滑油溜めを形成したことを特徴とする。
【００１３】
【発明の実施の形態】
図１は本発明の実施の形態を示す図である。本発明は従来装置の軸受け部周辺に改良を加えたものであり、全体構成はほぼ従来例の図３と同じであるため、要部についてのみ示してある。
【００１４】
既述のように従来装置では第１のシール部材４、第２のシール部材を備えている。ここで本発明では、例えばラジアルベアリング６及びスラストベアリング７が配置されている領域内に素材が入り込むことを防止する第２のシール部材５の直ぐ前方側に夫々第１の突起８１及び第２の突起８２が前後に隣接し、狭い隙間を介して設けられている。
【００１５】
前記第１の突起８１は動力伝達軸部３の表面上、全周に亘ってリング状に、かつ直径方向外側に突出して構成されている。図２に示してある動力伝達軸部３の表面と装置本体１内壁面と離間距離Ｄは例えば５０ミリであり、突起８１の縦断側面は前後幅Ｗ１が５０ミリ、内壁面との隙間Ｓ１が１ミリ程度となるように角型に形成されている。
【００１６】
第２の突起８２は装置本体内壁上全周に亘って直径方向内側にリング状の突起として構成されている。なお第２の突起８２はシール部材５の溝を形成している部材５０と一体的に記載しているが、実際には例えばこの部材５０とは別の部材を用い、その部材を部材５０にボルト締めで固定して取り付けられる。ここで図１では第１の突起８１と第２の突起８２が接しているが如く表されているが、図２に示す如く軸の回転する装置の構造上、微かな隙間８４が開いている。その間隔は素材が入り込まない程度に狭いことが好ましく、例えば０．３ｍｍ程度となっている。第２の突起８２と動力伝達軸部３との関係においても同様に例えば０．１ｍｍ程度の隙間が形成されている。
【００１７】
第１の突起８１と装置本体１の内壁面との間の隙間８３、第１の突起８１後面と第２の突起８２前面との間の隙間８４、及び第２の突起８２と動力伝達軸部３表面との間の隙間８５は縦断側面で見たときにクランク状の空間を形成する。
【００１８】
このような構成によれば装置に投入された繊維質素材が、その性状や投入領域における滞留状態等によって本来向かうべき前方の排出用開口部１１に向かわず、スクリュー羽根２１の回転力により、後方側に押しやられようとしても、突起８１、８２により阻止され、ここからシール部材５までの隙間８３、８４、８５は、前述のようにクランク状をなしているので素材が到達しにくく、仮に到達しても、後続の素材の押し込み力は直接第２のシール部材５に伝達されるおそれはないため、結果として繊維質素材による押し込み力によりシール部材５が変形するおそれはなくなり、封入されている潤滑油が素材投入領域へと流出することを防止でき（図４（ａ）（ｂ）参照）、装置のメンテナンス作業が軽減する。なお、本発明では既述のように第１の突起、第２の突起を設けてクランク状の隙間を形成することが好ましいが、どちらか一方の突起を設けるようにしてもよい。
【００１９】
一方、本発明はシール部材４よりも後方側の装置本体１においてスラストベアリング７が設けられている付近から下方側を凹ませて、回転軸停止時に潤滑油（オイル）がこの空間内に溜まってそのオイルレベル（図１に点線で示すＬ）がシール部材４、５よりも下方側になるように構成されている（図１）。
【００２０】
従って前述の突起８１及び突起８２の設置と併せて封入された潤滑油の流出防止効果を高めている。
【００２１】
【発明の効果】
本発明によれば素材投入領域とシール部材との間に突起を設けて、素材がシール部材へ押し込まれることを防止しているので、装置本体内に封入された潤滑油の流出が防止され、装置のメンテナンス作業が軽減する。

BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for expanding and softening and destroying fiber material tissues such as plant fiber materials and animal fiber materials.
[0002]
[Prior art]
Conventionally, plant fiber materials such as rice husks, sawdust, and tree hulls, or animal fiber materials such as wool waste, feathers, and leather are used for fertilizers, extenders, and fishery feeds for livestock poultry. An apparatus for expanding and softening and destroying a tissue of a fibrous material is known.
[0003]
Here, FIG. 3 is a sectional view of a conventional apparatus, and reference numeral 1 in FIG. 3 denotes a substantially cylindrical apparatus body having a discharge opening 11 formed at the front end and a material inlet 12 formed on the side surface. .
[0004]
Inside the apparatus main body 1, there is provided a processing shaft portion to which a material transfer screw blade 21 is attached, the diameter of which is reduced from the material input port 12 toward the front discharge opening 11. A power transmission shaft portion 3 is connected to the rear side of the processing shaft portion 2 in the axial direction. The power transmission unit 3 is supported by a front radial bearing 6 and a rear thrust bearing 7 which are bearings, and a pulley 22 connected in the axial direction behind the power transmission shaft has a force from a power source (not shown). Is transmitted by a belt or the like to obtain rotational force.
[0005]
Between the material inlet 12 and the radial bearing 6, the inner wall surface of the apparatus body 1 is machined in the circumferential direction, and grooves are formed in the front and rear at two places, and these grooves have a U-shaped cross section. Seal members 4 and 5 made of ring-shaped elastic bodies are fitted into the respective members. The first seal member 4 located on the rear side allows the material to enter the periphery of the bearing portion in which the lubricating oil is encapsulated, and the second seal member 5 located on the front side encloses the lubricating oil in the material input region side. Each of them is prevented from leaking into A seal member 8 having a similar configuration is also fitted in a ring shape behind the thrust bearing 7.
[0006]
According to such a conventional apparatus, the fiber material input from the material input port 12 is moved between the inner wall surface of the apparatus main body 1 while the screw blade 23 is transferred to the discharge opening 11 by the rotation of the rotary shaft 2. The fiber material is expanded and softened and destroyed by a series of steps in which the cut material is cut after being compressed by pressure and discharged from the discharge opening 11.
[0007]
[Problems to be solved by the invention]
However, in such a conventional apparatus, depending on the properties of the input fiber material, the staying state of the material in the input region, and the like, the screw blade 21 rotates in the reverse direction, that is, the U-shaped portion of the second seal member 5. In this state, when the material in the charging area is further pushed backward by the rotation of the screw blade 23, the pressing force has already accumulated in front of the U-shaped part. It is transmitted to the U-shaped part through the material.
[0008]
On the other hand, since the sealing member 5 is kept airtight by the elastic force of the elastic body, the sealing member 5 is deformed by the pressing force transmitted to the aforementioned U-shaped portion and the sealing member 5 and the apparatus main body 1 as shown in FIG. There is a possibility that a gap is formed between the inner wall surface and the material enters the bearing side through this gap, and the sealed lubricating oil may flow out to the machining shaft portion 2 side.
[0009]
The present invention has been made based on such circumstances, and is to reliably prevent leakage of the lubricating oil sealed behind the seal member and reduce maintenance work.
[0010]

Lubricating oil for bearings of the power transmission shaft portion enclosed between the power transmission shaft portion and the inside of the apparatus body;
A first seal member provided in a ring shape along the outer periphery of the power transmission shaft portion to prevent the lubricating oil from flowing out from the material input port into the material input region where the material is input;

Formed as

Further, when viewed from the longitudinal side surface, a portion on the extended line of the gap on the outer peripheral surface side of the first protrusion is recessed on the end surface of the second protrusion on the material input region side .
[0012]
In the present invention, when the rotation of the power transmission shaft portion is stopped, the lubricating oil reservoir is formed by denting the inner wall surface of the apparatus body below the power transmission shaft portion so that the liquid level of the lubricating oil becomes a level below the seal member. It is characterized by that.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a diagram showing an embodiment of the present invention. The present invention is obtained by improving the periphery of the bearing portion of the conventional apparatus, and the overall configuration is almost the same as that of FIG.
[0014]
As described above, the conventional apparatus includes the first seal member 4 and the second seal member. Here, in the present invention, for example, the first protrusion 81 and the second protrusion are respectively provided immediately on the front side of the second seal member 5 that prevents the material from entering the region where the radial bearing 6 and the thrust bearing 7 are disposed. The protrusions 82 are adjacent to each other in the front-rear direction and are provided via a narrow gap.
[0015]
The first protrusion 81 is configured to protrude in a ring shape and on the outer side in the diameter direction over the entire circumference on the surface of the power transmission shaft portion 3. The distance D between the surface of the power transmission shaft portion 3 and the inner wall surface of the apparatus main body 1 shown in FIG. 2 is 50 mm, for example, the longitudinal side surface of the projection 81 has a front-rear width W1 of 50 mm, and a clearance S1 between the inner wall surface. It is formed in a square shape to be about 1 mm.
[0016]
The second protrusion 82 is configured as a ring-shaped protrusion on the inner side in the diameter direction over the entire circumference on the inner wall of the apparatus main body. The second protrusion 82 is described integrally with the member 50 forming the groove of the seal member 5, but actually, for example, a member different from the member 50 is used, and the member is used as the member 50. It can be fixed by bolting. Here, in FIG. 1, the first protrusion 81 and the second protrusion 82 are shown as contacting each other. However, as shown in FIG. 2, a slight gap 84 is opened due to the structure of the device that rotates the shaft. . The interval is preferably narrow enough to prevent the material from entering, for example, about 0.3 mm. Similarly, in the relationship between the second protrusion 82 and the power transmission shaft portion 3, for example, a gap of about 0.1 mm is formed.
[0017]
A gap 83 between the first protrusion 81 and the inner wall surface of the apparatus main body 1, a gap 84 between the rear surface of the first protrusion 81 and the front surface of the second protrusion 82, and the second protrusion 82 and the power transmission shaft portion. The gap 85 between the three surfaces forms a crank-like space when viewed from the longitudinal side.
[0018]
According to such a configuration, the fibrous material thrown into the apparatus does not go to the front discharge opening 11 that should be originally directed due to its properties, the staying state in the throwing region, and the like, but by the rotational force of the screw blades 21, Even if it is pushed to the side, it is blocked by the projections 81, 82, and the gaps 83, 84, 85 from here to the seal member 5 are crank-shaped as described above, so that the material is difficult to reach and reaches temporarily. However, since the pushing force of the subsequent material is not directly transmitted to the second sealing member 5, the sealing member 5 is not likely to be deformed by the pushing force of the fibrous material, and is enclosed. Lubricating oil can be prevented from flowing out into the material input area (see FIGS. 4A and 4B), and the maintenance work of the apparatus is reduced. In the present invention, it is preferable to provide the first protrusion and the second protrusion to form the crank-shaped gap as described above, but either one of the protrusions may be provided.
[0019]
On the other hand, in the present invention, the lower part of the apparatus main body 1 behind the seal member 4 is recessed from the vicinity where the thrust bearing 7 is provided, and lubricating oil (oil) accumulates in this space when the rotary shaft is stopped. The oil level (L indicated by a dotted line in FIG. 1) is configured to be lower than the seal members 4 and 5 (FIG. 1).
[0020]
Accordingly, the effect of preventing leakage of the enclosed lubricating oil is enhanced in conjunction with the above-described installation of the protrusions 81 and 82.
[0021]
【The invention's effect】
According to the present invention, since the protrusion is provided between the material charging region and the seal member to prevent the material from being pushed into the seal member, the outflow of the lubricating oil enclosed in the apparatus main body is prevented, Equipment maintenance work is reduced.
