Soft extrusion spiral solid-liquid separation device

Abstract

The invention relates to a soft extrusion spiral solid-liquid separation device for separating waste solids from liquid, can be used for dehydration treatment of different materials, and is particularly suitable for separating various solid-liquid mixtures with the water content being80%-98%, the various solid-liquid mixtures include seaweed, paper pulp, sludge, biogas residue, various animal manures and the like, and the solid content of the yield can reach 30%-40%, so that the device is an ideal choice for farms, sewage treatment plants, paper mills, sugar mills, biogas plants and organic fertilizer plants.

Description

technical field [0001] The invention relates to the technical field of separation machinery, in particular to a soft extrusion screw solid-liquid separation device. Background technique [0002] With the development of the economy and the strengthening of people's awareness of environmental protection, urban wastewater treatment, farm waste, printing and dyeing wastewater, vegetable residues, etc. are all environmental problems to be solved in the environmental protection link. The solid-liquid separator of the prior art can be widely used Applied to fields such as farms, sewage treatment plants, paper mills, sugar factories, biogas plants, organic fertilizer plants, etc., the solid-liquid separation process can separate most of the suspended solids and hard-to-decompose solid substances in advance to reduce the The content of BOD, COD and refractory solid matter reduces the difficulty of the subsequent manure treatment process. Compared with anaerobic fermentation, it can ...

Problems solved by technology

This type of separator is suitable for treating manure with a solid content of 5% to 8%. When the solid content of the manure is low, the solid-liquid separation effect is not obvious

However, when the existing spiral solid-liquid se
