Spiral extrusion type solid-liquid separator

Abstract

The invention relates to solid-liquid separation devices, in particular to a spiral extrusion type solid-liquid separator. The spiral extrusion type solid-liquid separator comprises a machine frame, ashell, a screen cylinder and a packing auger, wherein the screen cylinder is arranged in the shell. The spiral extrusion type solid-liquid separator is characterized in that a solid discharge hole isformed in the left end of the shell, a motor for driving the packing auger is arranged at the right end of the shell, and a water outlet at the lower part of the shell is connected with a water suction pump. According to the spiral extrusion type solid-liquid separator, the largest length of the screen cylinder can reach 3 meters, so that the extrusion and drainage efficiency is greatly improved.

Description

technical field [0001] The invention relates to a solid-liquid separation device, in particular to a screw extrusion solid-liquid separator. Background technique [0002] When dealing with sludge, feces, and medicinal residues, the main structure of the screw extrusion solid-liquid separator is a horizontal cylindrical shell, and a sieve cylinder or a filter screen is arranged inside the shell. The length of the sieve cylinder cannot be set too long. About 500mm, the screw auger can be used to rotate to squeeze out the water, and the solid material can be discharged forward to realize the solid-liquid separation. The water content of the material before treatment is 80-90%, simply squeezed by the auger, and the waste water flows out automatically by gravity, so that the dehydration rate of the material is too low, and the solid-liquid separation effect is very poor. In order to facilitate the discharge of solid materials, there must be solid materials at the outlet of the s...

AI Technical Summary

Problems solved by technology

The water content of the material before treatment is 80-90%, simply squeezed by the auger, and the waste water flows out automatically by gravity, which makes the dehydration rate of the material too low and the solid-liquid separation effect is very poor

In order to facilitate the discharge of solid materials, there must be solid materials at the outlet of the screen cylinder to have a high extrusion force, and these solid materials occupy the length of 200-300mm of the screen cylinder, which reduces the length of the drainage area, resulting in solid Liquid separation efficiency is extremely low
