Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、その内部に送り羽根を有するコーン状の送
り軸を設けたスクリュープレスの外筒の改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of an outer cylinder of a screw press provided with a cone-shaped feed shaft having feed blades therein.
従来のスクリュープレスにおける外筒は、目抜き板に補
強を施したドラム内に２〜3m/mφの目を有する金網を張
設している。The outer cylinder in the conventional screw press has a wire mesh having a mesh of 2 to 3 m / mφ stretched in a drum whose reinforcing plate is reinforced.
このような従来のスクリーンドラムでは、例えば、下水
汚泥等の濃縮された汚泥で、その粒子が小さいもので
は、粒子が目から抜けて回収率が70〜80％と極めて悪
い。この回収率を向上させるには、金網の目を小さくす
ればよいのであるが、目を小さくすれば目詰りしやす
く、また、従来の金網では高圧をかけると破損する問題
があり、強度も上げなければならない。In such a conventional screen drum, for example, if the sludge is a concentrated sludge such as sewage sludge, and the particles are small, the particles come out of the eyes and the recovery rate is 70 to 80%, which is extremely poor. In order to improve this recovery rate, it is sufficient to make the mesh of the wire mesh small, but if the mesh is made small, it will easily become clogged.In addition, the conventional wire mesh has the problem of being damaged when high pressure is applied, and the strength is also increased. There must be.
この考案は、上述のような状況に鑑みて考案されたもの
であって、その目が1m/mφ以下の金網を重合して、これ
よりも細目の金網を形成し、このようにして細目で強度
を有する金網を支持枠体に張設したものである。This invention was devised in view of the above-mentioned situation, and its eyes were polymerized with a wire mesh of 1 m / mφ or less to form a wire mesh finer than this. A strong wire mesh is stretched over a support frame.
その要旨とするところは、多数の通孔を設けた半円筒状
の材の支持枠体を構成し、この支持枠体の内面に、メ
タルメッシュを複数段に積層して構成した材を張設

支持枠体の半体を合着して円筒状の外筒を構成したもの
である。The gist of the point is that a support frame made of a semi-cylindrical material with a large number of through holes is formed, and a material made by laminating metal mesh in multiple stages is stretched on the inner surface of the support frame. Then, the edge of this material is bent and fixed to the support frame body at the joint portion of the support frame body, and the half of the support frame body stretched with this metal mesh is joined to form a cylindrical outer surface. It is a cylinder.
このように、この考案に係る外筒は、従来の外筒よりも
その目が細目となり、小さな浮遊粒子を捕捉し、回収率
を高めることができる。そして、複数枚のメタルメッシ
ュが重合されて、しかも、このメタルメッシュが支持枠
体によって支持されているので、高圧力にも耐え高脱水
作業にも対応し得るものである。As described above, the outer cylinder according to the present invention has finer eyes than the conventional outer cylinder, and it is possible to capture small suspended particles and improve the recovery rate. Since a plurality of metal meshes are polymerized and the metal meshes are supported by the support frame, they can withstand high pressure and can be used for high dehydration work.
以下、図面に基づいてこの考案を説明する。The invention will be described below with reference to the drawings.
第１図において、符号１はコーン状の送り軸、２はその
周面に巻き回わした螺旋状の羽根、３はその内面に羽根
２が摺接する外筒であり、多数の通孔４が設けてある。
この外筒３は次のように構成してある。In FIG. 1, reference numeral 1 is a cone-shaped feed shaft, 2 is a spiral blade wound around its peripheral surface, 3 is an outer cylinder with which the blade 2 is in sliding contact with its inner surface, and a large number of through holes 4 are provided. It is provided.
The outer cylinder 3 is constructed as follows.
すなわち、第２図および第３図に示すように半円筒状の
支持枠体3aを構成し、その内面に半円筒状の多層に構成

着し、このように構成した半円筒状の支持枠体3aを合着
したものである。尚、図において、符号3d,3eは補強リ
ブを示すものである。That is, as shown in FIGS. 2 and 3, a semi-cylindrical support frame 3a is constructed, and a semi-cylindrical multi-layered metal mesh 3b is stretched on the inner surface of the support frame 3a. And the semi-cylindrical support frame 3a having the above-mentioned structure is joined together. In the figure, reference numerals 3d and 3e indicate reinforcing ribs.
この考案に係るスクリュープレスの外筒３は、上述のよ
うに構成してあり、すなわち、そのスクリーンがメタル
メッシュ（金網）を多層に重合したものであるので、そ
の目が細く、従って従来の外筒で捕捉できなかったスラ
リー中の微小粒子迄も捕捉することができる。また、メ
タルメッシュ自体が複数枚のメタルメッシュが重合され
ているので強度を有する上、支持枠体3aに一体に固着さ
れているので、高圧の過圧力に耐え高脱水ケーキを得
ることができる。The outer cylinder 3 of the screw press according to the present invention is configured as described above, that is, since the screen is made by polymerizing the metal mesh (wire mesh) in multiple layers, its mesh is thin, and therefore the conventional external Even fine particles in the slurry that could not be captured by the cylinder can be captured. In addition, the metal mesh itself has strength because a plurality of metal meshes are polymerized, and since it is integrally fixed to the support frame 3a, it is possible to endure a high pressure overpressure and obtain a highly dehydrated cake.
このように、この考案に係るスクリュープレスにおける
外筒は、従来のものに比較してスラリー中の微粒子迄も
捕捉でき、然も、強度を有するので、高圧力過が可能
であり、構造簡単であり乍ら、従来のフイルタプレス等
の加圧過機と同等の過作業を可能にしたもので、汚
泥等の処理作業上、得られる利益は著大なものである。As described above, the outer cylinder of the screw press according to the present invention can capture even fine particles in the slurry as compared with the conventional one, and since it has strength, it is possible to pass a high pressure and have a simple structure. However, it is possible to perform overwork equivalent to conventional pressurizing machines such as filter presses, and the profits obtained from sludge treatment work are enormous.
