A solid-liquid separator with automatic cleaning device

Abstract

The invention discloses a solid-liquid separator with an automatic washing device. The solid-liquid separator comprises a lower case, wherein a bottom plate of the lower case is an inclined plate; a left side plate and a right side plate of the lower case upwards extend; the upward extension parts of the lower case are right-angled trapezoidal plates; a screw extruder is arranged between the left side plate and the right side plate of the lower case; the left end of a packing auger sleeve extends towards the outside of the lower case; a residue outlet 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 case, of the packing auger sleeve; water-pervious holes are formed in the bottom of the packing auger sleeve and the bottom of 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-angled 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; a wastewater outlet is connected with a wastewater inlet; a cleaning water tank and a high-pressure water gun are arranged in the rear of the lower case; and the high-pressure water gun is capable of vertically and horizontally oscillating through a water gun oscillating device. The solid-liquid separator is simple in structure and reasonable in design.

Description

technical field [0001] The invention relates to a solid-liquid separator with an automatic cleaning device. 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 and mixing tank, and then separated from the water and dung through the solid-liquid separator with automatic cleaning device. The current solid-liquid separator with automatic cleaning device is mainly a screw extrusion mechanism to separate the water. In the organic fertilizer factory, the water enters the next treatment process. [0003] Due to the large water content of the aquaculture wastewater and the dispersion of the feces after stirring, the effect of using only the screw extr...

AI Technical Summary

Problems solved by technology

[0003] Due to the large water content of the aquaculture wastewater and the dispersion of the feces after stirring, the effect of using only the screw extrusion mechanism is poor. Therefore, it has become an industry insider to design a solid-liquid separator with an automatic cleaning device suitable for aquaculture wastewater. Technical problems that need to be solved urgently;

[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.
