Forced solid-liquid separator for feces of livestock and poultry

Abstract

The present invention discloses a forced solid-liquid separator for feces of livestock and poultry. The separator comprises a rack (1), a feeding hopper (2), a filtrate collection cell (3), a screen net separation mechanism and an extruding separation mechanism, wherein the screen net separation mechanism comprises four groups of springs (4), a screen net (5) and a vibration motor (6); the extruding separation mechanism comprises a sleeve (7), an extruding auger (8), a gear motor (9), a rack (10), a valve (11) and a reset spring (12). The forced solid-liquid separator has the advantages that the two-stage solid-liquid separation mechanism are adopted, so that the content of water in obtained solids is low, the solid-liquid separation effect is greatly improved, and the following fermentation efficiency is improved; by adopting structures of the reset spring and the valve, a condition that the content of water in extruded solids is relatively low is ensured, at the same time, due to elasticity of the reset spring, opposite acting force of materials to the extruding auger is reduced, and wearing of equipment is reduced; and the content of the water in extruded solids can be controlled by adjusting a screw rod.

Description

technical field [0001] The invention relates to the field of livestock and poultry manure treatment, in particular to a forced solid-liquid separator for poultry and poultry manure. Background technique [0002] With the adjustment of the agricultural industrial structure, the scale of livestock and poultry breeding is rapidly expanding, and the output of livestock and poultry manure is also increasing day by day. More than 80% of the farms do not have manure treatment facilities. The high concentration of manure not only pollutes the surrounding environment, but also causes , a large loss of phosphorus. Modern composting technology is the use of composting equipment to stabilize and harmless agricultural wastes by using aerobic microorganisms under aerobic conditions, and transform them into high-quality organic fertilizers that are beneficial to soil properties, beneficial to crop growth, and easy to absorb and utilize. method. [0003] Solid-liquid separation is a step ...

AI Technical Summary

Problems solved by technology

The separation effect of the existing screw extrusion solid-liquid separator is not good, and the moisture content of the separated solid is too high, and it cannot handle livestock and poultry manure with a large water content
