Sewage filtering device for food processing

Abstract

The invention belongs to the field of sewage treatment equipment and particularly relates to a sewage filtering device for food processing. The sewage filtering device comprises an upper base plate, alower base plate, side plates, a controller, a first-stage filtering unit and a second-stage filtering unit, wherein the upper base plate is arranged on the lower base plate by the side plates; the first-stage filtering unit is connected with a sewage inlet in the side plate through a pipeline; the second-stage filtering unit is positioned on the left side of the first-stage filtering unit; a first hairbrush unit is arranged on a sliding block of a rodless air cylinder through an air pressure rod and is positioned on the left side of a second hairbrush unit; the rodless air cylinder is fixedon the lower surface of the upper base plate; the first hairbrush unit comprises a first-stage plate, a second-stage plate, second-stage air pressure rods and hairbrushes; the second-stage plate is connected with the first-stage plate through the air pressure rod; and hairbrushes are uniformly arranged between the first-stage plate and the second-stage plate. The sewage filtering device disclosedby the invention is mainly used for graded filtering of sewage produced by a slaughter house and differentiated recovering of the sewage in the slaughter house; and the utilization rate of resources is improved while the labor cost is reduced.

Description

technical field [0001] The invention belongs to the field of sewage treatment equipment, in particular to a sewage filtering device for food processing. Background technique [0002] Commonly used slaughter sewage treatment devices involve civil engineering, occupy a large area, consume a lot of money, have a long operating cycle and high cost. Usually slaughterhouses process poultry and livestock and put them on the market as food; in the processing of poultry and livestock; sewage contains a lot of available resources; for example, poultry feathers can be made into clothes; poultry and livestock meat The shavings can be made into feed; the broken bones of poultry and livestock can be made into organic fertilizer; if the sewage from the slaughterhouse can be recycled reasonably, it can turn waste into treasure and make rational use of resources. [0003] There are also technical solutions for slaughter sewage treatment in the prior art. For example, a Chinese patent with a...

Problems solved by technology

Although this technical solution can realize the treatment of slaughterhouse wastewater and organic wastewater, the technical solution can only chemically decompose the sewage to achieve the treatment of sewage, and the residue generated during poultry and livestock processing cannot be recycled. The use of the invention is restricted
