Solid-liquid separator for separating livestock-poultry dung, biogas fluid and biogas dregs

Abstract

The invention relates to a solid-liquid separator for separating livestock-poultry dung, biogas fluid and biogas dregs, which belongs to a device for treating the livestock-poultry dung, the biogas fluid and the biogas dregs. The solid-liquid separator is provided a feeding section, a stirring section, a separating section, a solid material stockpiling section and a solid material discharging section which are arranged in turn along the axial direction of a helical blade auger assembly and are matched with a shell, wherein an auger shaft in the stirring section is provided with a stirring knife or a stirring rod; a separation screen assembly matched with the helical blade auger assembly is arranged on two relative lateral parts in the range of the separating section on the shell respectively; an elastic float positioning assembly is arranged on the shell, and is fixedly connected with the separation screen assembly on the same side; and the blade pitch of the helical blade auger assembly is gradually reduced from the rear lateral part of the separating section to the front part of the solid material stockpiling section. The solid-liquid separator has the advantages of scientific and reasonable operation process flow, novel structure, small resistance for separation operation, high separation efficiency, good separation quality, convenient operation, reliable use and fewer faults.

Description

technical field [0001] The invention belongs to livestock and poultry manure and biogas slurry and residue treatment equipment, and mainly relates to a solid-liquid separation machine for livestock and poultry manure, biogas slurry and biogas residue. Background technique [0002] Some pigs, cattle, sheep, chickens, ducks, geese and other livestock and poultry are industrialized and intensively farmed to bring people a wealth of meat. No matter how large the capacity is, it is limited. Livestock and poultry manure is in a fluid or semi-fluid state with a high water content. Such a large amount of manure cannot be handled and piled up like a mountain. A large amount of liquid livestock and poultry manure must be transported with manure buckets or tank trucks. , very cumbersome, and the transportation cost is high. As a result, the feces overflow, the smell is smoky, and the surrounding environment, air and waters are seriously polluted. In recent years, studies have shown th...

AI Technical Summary

Problems solved by technology

At present, equipment to adapt to the solid-liquid separation of livestock and poultry manure has come out, but due to the problems in structural design, its separation quality, separation effect, operation efficiency, convenience of use, power consumption and many other aspects need to be improved and improved.
