本発明は、下水や産業廃水等の汚泥をケーキと
水に分離する脱水装置の改良に係り、特にベルト
プレス型の高加圧脱水装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a dewatering device for separating sludge such as sewage or industrial wastewater into cake and water, and particularly relates to a belt press type high pressure dewatering device.
従来、下水や産業廃水等の汚泥の脱水に使用さ

れている。 Conventionally, vacuum dehydrators, centrifuges, filter presses, belt presses, and the like have been known as dewatering devices used for dewatering sludge such as sewage and industrial wastewater.
前記真空脱水機は構成機器が多い上、脱水性能

が悪いと云う難点がある。更に、フイルタ−プレ
スは脱水性能は良いが、構成機器が大型で設備費
等が大幅に高いと云う難点がある。 The vacuum dehydrator has many components and has relatively poor dehydration performance. Further, although the centrifugal separator itself is small and efficient, it has the disadvantage of poor dewatering performance. Furthermore, although the filter press has good dewatering performance, it has the disadvantage that its constituent equipment is large and the equipment cost is significantly high.
一方、ベルトプレスは脱水ケーキ水分が65〜75
％であり、真空脱水機・遠心分離機とフイルター
プレスの中間に位置する性能を持つていると評価

小さく、設備費等についても前記と同様中位であ
る。 On the other hand, the belt press has a dehydrated cake moisture of 65 to 75.
%, and is evaluated as having performance that is between vacuum dehydrators/centrifuges and filter presses. In addition, there are few components, the installation area is small, and equipment costs are also average, as mentioned above.
特に、ベルトプレスは前記した評価が最近の汚
泥処理設備の小型化、省エネルギー化の指向に一
値している為、多く利用されている。 In particular, belt presses are widely used because the above-mentioned evaluations are consistent with the trend towards downsizing and energy saving of recent sludge treatment equipment.
第４図及び第５図は従来のベルトプレスの概略

後者は前記と同構造のものに加圧ベルト４′（金
網・ゴムベルト等）を付加して構成されて居り、
該加圧ベルト４′により脱水ケーキの水分をい更
に下げるようにしている。 FIGS. 4 and 5 are schematic side views of a conventional belt press. The sludge is sandwiched between the sludge and the lower cloth 3' and is repeatedly wound around several rollers to apply squeezing force and shearing force to the sludge for dewatering. or,
The latter is constructed by adding a pressure belt 4' (wire mesh, rubber belt, etc.) to the same structure as above,
The pressure belt 4' further reduces the moisture content of the dehydrated cake.
然し乍ら、前記両者は布又は加圧ベルトの張
力を押圧力に変換するもので、通常汚泥の圧搾圧
力は２Kg／cm2程度が限度であり、脱水性能が悪い
と云う難点がある。 However, both of the above convert the tension of a cloth or pressure belt into pressing force, and the pressing pressure of sludge is usually limited to about 2 kg/cm 2 and has the drawback of poor dewatering performance.
又、第６図及び第７図に示すドラムプレスは、

介して汚泥に直接押圧力を加えている。従つて、
圧搾圧力は５Kg／cm2程度になり、前記両者に比べ
て脱水性能は良くなつている。 In addition, the drum press shown in FIGS. 6 and 7 is
It consists of a wheel 5', a caterpillar 6', a lower cloth 7', a pressure roller 8', a drum 9', an upper cloth 10', a plastic rope 11', and a hopper 12'. A pressing force is applied directly to the sludge through the pipe 6'. Therefore,
The squeezing pressure is about 5 kg/cm 2 , and the dewatering performance is better than both of the above.
然し乍ら、このドラムプレスは流動性汚泥（水
分が97〜98％）を直接脱水するには難点がある。
何故なら、本機は重力脱水ゾーンを持たないため
濃縮されていない汚泥が布の両サイドからはみ

分な押圧力が掛らない為である。又、加圧ローラ

加圧ローラ８′の両端側を汚泥に押付けて加圧力
を発生させている為、加圧ローラ８′が撓んだり
或は軸径にも限界があり、高押圧力が得にくかつ
た。 However, this drum press has a drawback in directly dewatering fluid sludge (97 to 98% water content).
This is because this machine does not have a gravity dewatering zone, so unconcentrated sludge protrudes from both sides of the cloth, or the cake is thin due to its low concentration, and insufficient pressing force is applied. Further, a shaft 13' passes through the pressure roller 8', and both ends of the shaft 13' are supported by a pressure frame 14', and the pressure frame 14' presses both ends of the pressure roller 8' against the sludge. Since the pressurizing force is generated by the pressurizing roller 8', the pressurizing roller 8' may be bent or there is a limit to the shaft diameter, making it difficult to obtain a high pressurizing force.
本発明は、上記の問題点を解決する為に創案さ
れたものであり、その目的は流動性汚泥でも良好
に脱水できると共に、高押圧力を得られる高加圧
脱水装置を提供するにある。 The present invention was devised to solve the above-mentioned problems, and its purpose is to provide a high-pressure dewatering device that can satisfactorily dewater even fluid sludge and can obtain a high pressing force.
