A farming wastewater and slag separator with a filter screen swinging up and down cleaning device

Abstract

The invention discloses a breeding wastewater dreg separator with a filter screen bobbing washing device. The separator is characterized in that a bottom plate of a 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 bottom of the auger sleeve; 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; 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 a wastewater inlet; a washing water tank and high-pressure water guns are arranged in the rear of the lower tank; the high-pressure water guns achieve bobbling via water gun bobbling devices; screen bars of the filter screen are shaped like triangular prisms. The separator has a simple structure and is reasonable in design.

Description

technical field [0001] The invention relates to a farming wastewater and slag separator with a filter net swinging up and down 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 mixing tank, and then separated from the water and feces through the aquaculture wastewater slag separator with a filter screen swinging up and down cleaning device. The current aquaculture wastewater slag separator with a filter screen swinging up and down cleaning device is mainly The screw extrusion mechanism separates the water, the manure is used in the organic fertilizer plant, and the water enters the next treatment process. [0003] Due to the...

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, designing a water slag separator suitable for the aquaculture wastewater has become an urgent need for the industry. question;

[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.

[0005] Secondly, the current filter screen is either a filter screen formed by sieve bars arranged in warp and weft, or it is composed of a number of support bars arranged side by side and a number of sieve bars vertically connected to the support bars. The sieve bars are all rectangular bars. When water flows through, the residence time Short, can't play a good role in filtering water
