A breeding wastewater slag liquid separator capable of automatically cleaning the filter screen

Abstract

The invention discloses an aquaculture wastewater residue-liquid separator capable of automatically cleaning a filter screen. The aquaculture wastewater residue-liquid separator comprises a lower tank body and a residue receiving pan, wherein a bottom plate of the lower tank body is an inclined plate; a left side plate and a right side plate of the lower tank body upwards extend; the upward extension parts of the lower tank body are right trapezoidal plates; a screw extruder is arranged between the left side plate and the right side plate of the lower tank body; the left end of a packing auger sleeve extends towards the outside of the lower tank body; a slag hole is formed in the lower side of the end part of the extension part of the packing auger sleeve; a feeding hole is formed in the upper side of the part, which is located in the lower tank body, of the packing auger sleeve; water permeating holes are formed in the bottoms of the packing auger sleeve and the extension part of the packing auger sleeve; a wastewater collecting tank is arranged below the extension part of the packing auger sleeve; a wastewater buffer tank is arranged between the upper parts of the right trapezoidal plates; a filter screen is arranged between a front side plate of the wastewater buffer tank and a rear side plate of the feeding hole of the packing auger sleeve; and a wastewater outlet is connected with a wastewater inlet. A cleaning water tank and a high-pressure water gun are arranged inside the rear part of the lower tank body. The vertical oscillation and horizontal oscillation of the high-pressure water gun are realized through a water gun oscillation device. The aquaculture wastewater residue-liquid separator is simple in structure and reasonable in design.

Description

technical field [0001] The invention relates to a breeding wastewater residue liquid separator capable of automatically cleaning the filter screen. Background technique [0002] Breeding wastewater is mainly composed of waste water and pig manure from flushing pig houses. The water content is large, but there are also a lot of dung residues. At present, the treatment process for aquaculture wastewater is mainly to first pass the wastewater through the grid tank to remove large impurities. , and then stirred in the water collection mixing tank, and then separated from the water and dung through the aquaculture wastewater slag liquid separator that can automatically clean the filter screen. The current aquaculture wastewater slag liquid separator that can automatically clean the filter screen is mainly a screw extrusion mechanism The water is separated, the manure is used in the organic fertilizer plant, and the water enters the next treatment process. [0003] Due to the lar...

AI Technical Summary

Problems solved by technology

[0003] Due to the large water content of the aquaculture wastewater, and the dispersion of the excrement after stirring, the effect of only using the screw extrusion mechanism is poor. Therefore, it is urgent to design a water slag liquid separator suitable for the aquaculture wastewater. technical problem;

[0004] In addition, at present, the cleaning of the filter screen of the solid-liquid separator needs to be disassembled and cleaned manually, and the cleaning efficiency is low.
