The centrifugal water machine is a continuous dewatering device, but its treatment capacity is limited, and the sludge is a highly hydrophilic substance, and it is difficult to effectively dewater the sludge. Although the plate and frame filter press is an intermittent dewatering device, it can process a large amount of wet sludge at a time and can withstand a large hydraulic pressure, so the dewatering effect is good, and it is the main device for dewatering of wet sludge at present.
用板框压滤机压滤后的污泥一般含水率在 60%， 而此污泥则被压滤成很大 的块状物， 通常的处理方法是将这些块状的污泥破碎成小块， 然后再输送到搅 拌机内与其他物料混合， 再送去干燥。 这种间歇式的湿污泥脱水方法， 处理效 率不高， 容易造成工厂生产的脱节。 发明目的  The sludge after filtration by the plate and frame filter press generally has a water content of 60%, and the sludge is pressure-filtered into a large mass. The usual treatment method is to crush the bulk sludge into small pieces. The block is then transferred to a blender for mixing with other materials and sent to dryness. This batch method of wet sludge dewatering is not efficient, and it is easy to cause disjointed factory production. Purpose of the invention
