High-efficiency energy-saving belt filter press

Abstract

The invention discloses a high-efficiency energy-saving belt filter press which comprises a frame, a filter press belt, a hopper and a motor, and is characterized in that a material equalizing regulation device is arranged at a discharging end of the frame; the filter press belt is a double-layer filter cloth belt; a four-stage press filtering mechanism is arranged on the discharged filter press belt at intervals; a vacuum suction filtration disc for vacuumizing by utilizing a vacuum pump is arranged below the filter press belt behind a mesh cage roller; a tail gas cleaning mesh-cleaning roller and a filter press belt gas ejector pipe are respectively arranged on the mesh cage roller and on a belt return part of the filter press belt. The machine is uniform in feeding, long in service life, stable in performance, good in dewatering effect and high in yield, and the filter belt is difficult to block; the slag adhered to the mesh cage roller and the filter press belt is subjected to air injection cleaning by utilizing the vacuum pump tail gas, and water and electric energy are saved; and the machine is suitable for squeezing and dewatering manioc waste, cassava residues, bean dregs and distillers grains and water-containing raw materials in the industries such as municipal sludge, chemical industry, oil refining, papermaking and sugar refining.

Description

technical field [0001] The invention relates to a separation device, in particular a filter press for squeezing liquid from liquid-containing solid matter. Background technique [0002] The filter press that squeezes out the liquid from the solid material containing the liquid and separates the liquid from the solid material is widely used, and there are many types and structural types of existing filter presses. There are single-belt and double-belt filter presses commonly used for dewatering slag, sludge and bad substances. According to the material of the transmission belt, there are filter cloth belt filter presses and plastic belt filter presses. Their structures are basically The same is to use the transmission belt and the roller to squeeze the raw material on the transmission belt, so that the water is separated from the material body. It is mainly used in pressing and dehydrating raw materials containing water in industries such as cassava residue, cassava dis...

AI Technical Summary

Problems solved by technology

[0003] 1. The feed is not uniform, and the effect of pressing and dehydration is poor;

[0004] 2. The filter belt is easy to block, the force strength is small, and the service life is short;

[0005] 3. The power of the upper and lower rollers of the press is small, easy to slip, and the work efficiency is low;

[0006] 4. The transmission power is large and requires many power sources;

[0007] 5. Use a lot of water to clean the viscous material on the roller and filter belt, which wastes energy;

[0008] 6. The dehydration effect is poor, the speed is slow, and the output is not high
