〔産業上の利用分野〕
この発明は、スクリュープレスの運転方法並びにその装
置に関し、この発明では土砂排水汚泥の如く、非圧搾性
の無機質の粒子を含む汚泥の圧搾に用いて卓効を奏する
運転方法並びに運転装置を提供せんとするものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method of operating a screw press and an apparatus therefor. The object of the present invention is to provide an operating method and an operating device that can be used effectively.
スは、固定した外筒内にスクリュー軸を支架して、その
スクリューで外筒の一端に供給した汚泥を他端に向って
搬送しつつ圧搾して固液分離をしている。A screw shaft is supported in a fixed outer cylinder, and the screw transports the sludge supplied to one end of the outer cylinder toward the other end while compressing it to separate solid and liquid.
然し４から、土砂排水汚泥の如く無機質の粒子よりなる
汚泥は、一定のところまで圧搾すると粒そして、このよ
うな状態で、はらに加圧圧搾すると遂には、スクリュー
羽根や外筒がこわれるおそれがある。この発明は、一定
限度の加圧圧搾をした場合、スクリューや外筒に無理の
かからぬように、これらが共回わりするようにするとと
もに、この共回わりを自動的に停止して再び加圧圧搾運
転ができるようにしたものである。However, from 4, sludge consisting of inorganic particles, such as sediment drainage sludge, becomes grainy when squeezed to a certain point, and if the sludge is squeezed under such conditions, there is a risk that the screw blades and outer cylinder may eventually break. be. This invention allows the screw and outer cylinder to rotate together so as not to force the screw or the outer cylinder when compressed to a certain limit, and also automatically stops this rotation and presses the screw again. It is designed to allow compression operation.
この発明では、］＝述のような作動をなさしめるために
次のような手法・手段を講じたものである。In this invention, the following methods and means are taken to achieve the operation as described above.
すなわち、外筒をスクリューに対して回転可能に支架し
たスクリュープレスにおいて、外筒に一定のトルク以下
ではその回転を係止することができる係止装置を設け、
その係止装置と少なくとも外筒周辺に設けた高圧流体の
噴射ノズルへの高圧流体の供給ポンプ七を連動連結して
外筒に一定以上のトルクがかかったとき、噴射ノズルか
ら高圧流体を噴射するようにしたものである。That is, in a screw press in which an outer cylinder is rotatably supported with respect to a screw, a locking device that can lock the rotation of the outer cylinder below a certain torque is provided on the outer cylinder,
The locking device is interlocked with at least a high-pressure fluid supply pump 7 to a high-pressure fluid injection nozzle provided around the outer cylinder, and when a torque of a certain level or more is applied to the outer cylinder, high-pressure fluid is injected from the injection nozzle. This is how it was done.
この発明における外筒は、スクリューによって汚泥等が
順調に搬送圧搾されているときには、その回転が停止し
ている。The outer cylinder in this invention stops rotating when the sludge and the like are being smoothly conveyed and compressed by the screw.
次に、汚泥等の圧搾物がスクリューと外筒との間に充満
したときには、スクリューと一体となって共回わりをす
るものである。Next, when the space between the screw and the outer cylinder is filled with compressed material such as sludge, it rotates together with the screw.
すなわち、このように汚泥等の圧搾物が充満したときに
無理にスクリューを駆動すると外筒やスクリューが破損
し、遂には機械自体が破損するのであり、特に、土砂排
水汚泥の如く非圧縮性の汚泥の場合にはこの傾向が顕著
であるが、この発明では圧搾物が充満したとき、外筒が
スクリューと共回わりをするので、上述のような破損・
破壊をまぬがれることができる。In other words, if the screw is forcibly driven when it is filled with compressed material such as sludge, the outer cylinder and screw will be damaged, and eventually the machine itself will be damaged. This tendency is noticeable in the case of sludge, but in this invention, when the compressed material is filled, the outer cylinder rotates together with the screw, so there is no possibility of damage or damage as described above.
You can avoid destruction.
然も、この発明では、外筒が共回わりを始めるのに連動
して外筒周辺に設けた噴射ノズルから高圧流体を外筒に
向けて噴出するのでこの流体が外筒の目を通ってその内
面に達し、圧搾物との接触面を潤し、接触面をスリップ
させる。However, in this invention, when the outer cylinder starts to rotate, high-pressure fluid is ejected toward the outer cylinder from the injection nozzle provided around the outer cylinder, so this fluid passes through the eyes of the outer cylinder. It reaches its inner surface, moistens the contact surface with the pressed material, and causes the contact surface to slip.
この結果、圧搾物はスクリューによって排出口へと送ら
れ圧搾脱水運転を継続することができる。As a result, the compressed material is sent to the discharge port by the screw, and the compressing and dewatering operation can be continued.
すなわち、この発明では外筒に過大な負荷がかかれば、
自動的に高圧流体によって外筒を洗滌すると同時に過大
な負荷を取除いて連続した運転をすることができるもの
である。In other words, in this invention, if an excessive load is applied to the outer cylinder,
It is capable of continuous operation by automatically cleaning the outer cylinder with high-pressure fluid and removing excessive loads at the same time.
以下、図面にしだがって、この発明を具体的に説明する
。The present invention will be specifically described below with reference to the drawings.

筒１の゛スクリーンを破壊する事態が生ずる。However, if the supplied raw solution consists of incompressible particles such as sediment and drainage sludge, if the above-mentioned operation is continued, the outer cylinder 1 and the screw shaft 2 will collapse due to the incompressibility of the sediment particles. Not only will the cake fill and clog the gap and dehydration will not occur, but the subsequent cake will destroy the screen of the outer cylinder 1, which is the weakest.
このような場合、この発明では外筒１が回転可能に支架

かけられた状態にあるので、その隙間がケーキで充満し
たときには、スプリング８のブレーキ力に打ち勝ってス
クリュー軸２と外筒１ト力共回わりをして破損を防止す
ることができる。In such a case, in this invention, the outer cylinder 1 is rotatably supported and its rotation is braked by the spring 8, so when the gap is filled with cake, the braking force of the spring 8 is applied. This allows the screw shaft 2 and the outer cylinder to rotate together with one torque, thereby preventing damage.
そして、このスクリュー軸２と外筒１との共回わりは、

運転を再開することができる。The co-rotation of this screw shaft 2 and outer cylinder 1 is as follows:
It is detected by the sensor 12, and the signal activates the high-pressure pump, which injects high-pressure water into the outer cylinder 1 using the cleaning nozzle 9a, removing the clogged matter from the screen, and moistening the inner surface of the outer cylinder I to clean the screw. The compressing operation can be restarted by rotating the shaft 2.

プ１０の洗浄水をノズル管１３に送るものである。Of course, the screen cleaning and wetting operations using high-pressure water described above can also be performed on the screen of the feed shaft 2. In the illustrated system, cleaning and lubrication of the screen of the feed shaft 2 is performed using the nozzle 13 which normally sucks furnace liquid. It is sent to the pipe 13.

自動運転を可能としたものである。゛As described above, in this invention, whenever the pressed material fills the outer cylinder and becomes impossible to compress and starts to rotate together with the screw shaft 2, the eyes of the outer cylinder 1 and the screw shaft 2 are cleaned. This allows the screw shaft 2 to rotate independently, automatically restarts the compressing operation, and repeats this operation to enable continuous automatic operation.

。In this way, the present invention provides a screw press in which an outer cylinder is rotatably supported on a screw shaft, and when the screen portion becomes clogged and the outer cylinder and screw shaft begin to rotate together as a unit, cleaning is possible. This system injects high-pressure fluid from the nozzle into the clogged area to remove the clog, separates the screen and cake part, rotates the screw shaft, and automatically restarts the squeezing operation. During high-pressure squeezing work using a screw press. It is possible to prevent damage to the machine body, and in particular, the work efficiency of the screw press can be greatly improved in that continuous operation can be performed while the screen is being regenerated.
