A breeding wastewater slag-liquid separator for convenient cleaning of the filter screen

Abstract

The invention discloses a breeding wastewater dreg and liquid separator convenient for washing a filter screen. The separator comprises a lower tank and a dreg receiving plate, wherein a bottom plate of the lower tank is an oblique plate; left and right side plates of the lower tank extend upwards; the upward extension parts of the lower tank are right-angled trapezoidal plates; a screw-type extruder is installed between the left and right side plates of the lower tank; the left end of an auger sleeve extends out of the lower tank; a dreg outlet is formed in the lower side of the end of an extension part of the auger sleeve; a feeding hole is formed in the upper side of the part, in the lower tank, of the auger sleeve; water permeable holes are formed in the bottoms of the auger sleeve and the extension part thereof; a wastewater collecting tank is arranged below the extension part of the auger sleeve; a wastewater buffer tank is arranged between the upper parts of the right-angled trapezoidal plates at the left and right sides; a wastewater inlet is formed in a back plate of the wastewater buffer tank; 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 auger sleeve; a wastewater outlet is connected with the wastewater inlet; a washing water tank and high-pressure water guns are arranged in the rear of the lower tank. The separator has a simple structure and is reasonable in design.

Description

technical field [0001] The invention relates to a breeding wastewater slag liquid separator which is convenient for 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 feces by the aquaculture wastewater slag liquid separator that is convenient for cleaning the filter screen. The current aquaculture wastewater slag liquid separator that is convenient for cleaning the filter screen is mainly a screw extrusion mechanism Separation, the manure is used in the organic fertilizer plant, and the water enters the next step of the treatment process. [0003] Since the water ...

AI Technical Summary

Problems solved by technology

[0003] Since the water content of the aquaculture wastewater is relatively large, and the excrement is dispersed after being stirred, the effect of only using the screw extrusion mechanism is poor. Therefore, it is necessary to design a breeding wastewater slag liquid separator suitable for the convenient cleaning filter screen of the aquaculture wastewater. Technical problems urgently needed to be solved by industry insiders;

[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.
