Description

本発明は廃水処理等用排水中の微細浮遊物或いはプリント配線板剥離カス等の夾雑物を振動スクリーンにより分離、除去するための夾雑物を含有した排水の微細浮遊物除去装置に関する。 The present invention relates to a device for removing fine floating substances from wastewater containing impurities for separating and removing fine floating substances in wastewater for wastewater treatment and the like or contaminants such as printed wiring board peeling residue with a vibrating screen.

各種の汚水、洗浄排水等の処理に際し、この排水中にチップ屑、毛類、動物の糞中にある繊維状物を含む場合これら夾雑物は形状が細長く、かつ軽いために篩を用いると篩面に付着して目詰まりを起こしやすく、また沈積除去するには浮遊して不利である。 When processing wastewater, washing wastewater, etc., if wastewater contains chip waste, hair, or fibrous materials in animal feces, these contaminants are slender and light, so if a sieve is used, Adhering to the surface is likely to cause clogging, and floating is disadvantageous for removing the deposit.

本発明者は先に排水中の繊維状夾雑物を除去する装置を発明した（特許文献１参照）。この装置は前部上方に原水流入管に連なる溢流樋ならびに下方に取出管を設け、後部に固形物シュートに連なる固形物取出口を設けた槽体の内部に、微細目の金網を張装した平板状の篩を前端近くの槽体に横設した高速回転する偏心軸に受支取付し、後端をスプリングにより弾発的に支持してほぼ水平に架設すると共に、篩下方には上方に噴射する散水管を設け、更に篩の後端にはそれぞれ上縁を重合して広幅の２枚のゴム板を、一方は槽体の後壁に内面に、また他の一方は固形物シュート上面に各添わせて垂下取付けてなる排水中の繊維状夾雑物を除去する装置である。   The inventor previously invented an apparatus for removing fibrous impurities in waste water (see Patent Document 1). This device has an overflow basin connected to the raw water inflow pipe above the front and a take-off pipe below, and a fine wire mesh is installed inside the tank body provided with a solid material outlet connected to the solid chute at the rear. The plate-shaped sieve is mounted on a high-speed rotating eccentric shaft installed in the tank body near the front end, and the rear end is elastically supported by a spring and installed almost horizontally. Water spray pipes are sprayed on the top of the screen, and the upper edge is superposed at the rear end of the screen to create two wide rubber plates, one on the inner wall of the rear wall of the tank body and the other on the solid chute It is an apparatus for removing fibrous impurities in the waste water that are attached to the upper surface depending on the hanging.

即ち、この装置は篩の一方を高速回転する偏心軸に受支取付け、他端をスプリングによって弾発的に支持して篩自体を揺動させ、篩面上に供給された繊維状夾雑物を含有する液体は篩により繊維夾雑物と液体とに分離され、液体は篩下に流下するともに篩面上に残された繊維状夾雑物は篩の振動によって篩面に生じるぜん動状の造粒作用を受けて点在する粒状にまるめられながら篩の後端に向かって前進し、最後に固形物シュート上に落下するのである。
しかし、この装置をプリント配線板の剥離液を原水として処理しようとすると、剥離液中の剥離かすは近年ますます微細化され、篩のろ過面に使用する金網は微細メッシュ３００〜３５０メッシュでの連続処理が要求されるが、現状では２００メッシュが限度で任意の処理ができない。 That is, in this apparatus, one end of a sieve is supported on an eccentric shaft that rotates at high speed, the other end is elastically supported by a spring, the sieve itself is swung, and fibrous impurities supplied on the sieve surface are removed. The contained liquid is separated into fiber contaminants and liquid by a sieve, and the liquid flows down under the sieve and the fibrous contaminants remaining on the sieve surface are a peristaltic granulation action that occurs on the sieve surface due to vibration of the sieve. In response to this, the particles move forward toward the rear end of the sieve while being rounded into scattered particles, and finally fall onto the solid chute.
However, if this device is used to treat the stripping solution of the printed wiring board as raw water, the stripping residue in the stripping solution has been increasingly refined in recent years, and the wire mesh used for the filtration surface of the sieve has a fine mesh of 300-350 mesh. Although continuous processing is required, at present, arbitrary processing is not possible with a limit of 200 mesh.

更に、この装置では原水を原水流入管に連なる溢流樋からオーバーフローさせて一定の個所に落とすため、原水のろ過面積が狭く微細メッシュによる処理が困難であり、原水落下点の後部に固形物が多少残留し固形物残さが前面に滞留しやすいという欠点があった。 Furthermore, in this device, the raw water is overflowed from the overflow basin connected to the raw water inflow pipe and dropped to a certain place, so the filtration area of the raw water is small and it is difficult to treat with the fine mesh, and there is solid matter at the rear of the raw water falling point. There was a drawback that some solids remained and the solid residue remained on the front surface.

本発明者は上記の欠点を改良すべく種々検討した結果、本発明を完成したのであって、本発明の目的は処理水量が増大し、しかもろ過面の清掃効果によって目詰まりなく、安心して微細メッシュ（３５０メッシュ）によって微細な剥離かすが連続的に除去できる夾雑物を含有した排水の微細浮遊物除去処理装置を提供するにある。   As a result of various studies to improve the above-mentioned drawbacks, the present inventor has completed the present invention. The object of the present invention is to increase the amount of treated water and to prevent the clogging by the cleaning effect of the filtration surface. The object of the present invention is to provide a device for removing fine suspended solids from wastewater containing impurities capable of continuously removing fine exfoliation debris with a mesh (350 mesh).

即ち、本願発明の要旨は、上面に開口部を有し、前壁に原料流入管を、後壁に液体取出管及び固形物シュートに連なる固形物取出口を設けた長方形状の槽体よりなる夾雑物を含有した排水の微細浮遊物除去処理装置であって、前記開口部には揺動運動を行えるように平板状のフィルターをほぼ水平に架設すると共に、フィルターのろ過面積を広範囲に利用するため前記原料流入管が前壁から後壁に向かって水平往復運動を行える分岐管に連なり、該分岐管より原料液体を前記フィルターに流下、供給して液体と固形物とに分離することを特徴とする夾雑物を含有した排水の微細浮遊物除去処理装置である。   That is, the gist of the present invention consists of a rectangular tank body having an opening on the upper surface, a raw material inflow pipe on the front wall, and a solid material outlet connected to the liquid extraction pipe and solid chute on the rear wall. A device for removing fine suspended solids from wastewater containing foreign substances, in which a flat plate-like filter is installed almost horizontally so as to be able to swing in the opening, and the filter's filtration area is widely used. Therefore, the raw material inflow pipe is connected to a branch pipe that can perform a horizontal reciprocating motion from the front wall to the rear wall, and the raw material liquid flows down to the filter from the branch pipe and is supplied to separate into liquid and solid matter. It is the fine floating substance removal processing apparatus of the waste_water | drain containing the foreign material to be.

本発明においては原料流入管の先端を複数の管に分岐し、分岐管全体を連続水平往復移動させることにより、フィルターのろ過面積を広範囲に拡大させることができ、原料水はポンプ圧送により分岐管に供給される原料水には適度のポンプ圧が加わり、微細メッシュでも原料水の押込圧によって処理量は増大し、さらに、分岐管によって篩面に供給された原料水は、原料水と原料水の間に一定の空間が保持されており、後進移動時は後部に残った夾雑物が篩の揺動運動との相互作用で、その空間より前進し篩上に夾雑物が残らず、篩面の清掃効果が大で連続運転ができ、その結果３００〜３５０メッシュという微細な金網をフィルターとして使用できる。更に分岐管の前進移動時の距離を任意に設定でき、夾雑物の篩面への排出の早さを調整できる等の効果を奏することができる。   In the present invention, the tip of the raw material inflow pipe is branched into a plurality of pipes, and the entire branch pipe is continuously reciprocated horizontally, whereby the filtration area of the filter can be expanded over a wide range. Appropriate pump pressure is applied to the raw material water supplied to the slag, and the throughput increases due to the pushing pressure of the raw material water even with a fine mesh. Furthermore, the raw water supplied to the sieve surface by the branch pipe is divided into raw water and raw water. During the backward movement, the foreign matter remaining in the rear part moves forward from the space due to the interaction with the swinging motion of the sieve, and no foreign substance remains on the sieve. The cleaning effect is large and continuous operation is possible. As a result, a fine wire mesh of 300 to 350 mesh can be used as a filter. Furthermore, the distance at the time of the forward movement of the branch pipe can be set arbitrarily, and effects such as the ability to adjust the speed of discharge of impurities to the sieve surface can be achieved.

For example, for example, the front end portion of the filter is received by an eccentric shaft that rotates at a high speed and is provided in a tank body near the front end of the filter. The filter can be swung by supporting the support and resiliently supporting the rear end portion with a spring. Further, in this apparatus, the branch pipe moving means connected to the raw water supply pipe swings the raw water supply pipe back and forth via the swivel joint, and horizontally moves the tip of the branch pipe.
