Novel circulation type sewage treatment tank

Abstract

The invention discloses a novel circulation type sewage treatment tank. The novel circulation type sewage treatment tank comprises a tank body, wherein a water inlet is formed in the top end of an outer wall of the tank body; an inner wall of the water inlet is connected with the outer wall of the tank body; a water outlet is formed in the bottom end of the outer wall of the tank body; the inner wall of the water outlet is connected with the outer wall of the tank body; supporting legs are mounted at the bottom end of the outer wall of the tank body; the upper surfaces of the supporting legs are hinged to the lower surface of the tank body; a supporting rod is hinged to a right-side outer wall of the tank body; a left-side outer wall of the supporting rod is welded and connected with the right-side outer wall of the tank body; a protection cover is hinged to the upper surface of the supporting rod. According to the novel circulation type sewage treatment tank, a motor, a worm rod, a belt, a first gear and a second gear are matched; the motor is an alternating-current servo motor and the size of power which is generated when current passes through the motor is adjusted under the action of a bent rod, so that the rotary speed of the motor is adjusted; the rotary speed of the motor is adjusted so that the novel circulation type sewage treatment tank is suitable for being popularized and applied.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a novel circulating sewage treatment tank. Background technique [0002] In recent years, with the rapid development of society, there are more and more processing and manufacturing enterprises, and the amount of industrial wastewater discharged is increasing. Various enterprises pay more and more attention to how to deal with industrial wastewater, and the total amount of sewage discharge continues to increase. Treatment The increasing difficulty has brought a lot of trouble to sewage treatment. Nowadays, industrial production materials, intermediate products and products that are lost with water, as well as pollutants generated in the production process, with the rapid development of industry, waste water The types and quantities of the waste water are increasing rapidly, and the pollution of the water body is becoming more and more extensive and serious, threatening h...

Problems solved by technology

In order for these sewage treatment stations to really play a role, it is necessary to rely on strict discharge systems, organizations and management systems to ensure that in the prior art, for example, the invention patent with application number 201720232509.8 includes sewage treatment tanks, and the sewage treatment tanks are equipped with There is a sewage rotating cylinder, the rotating shaft of which is connected to the first motor installed on the top of the sewage treatment tank. The side cylinder wall and the bottom wall of the cylinder are all covered with activated carbon filter plates, and the top of the sewage treatment tank is connected with a suction pipe, and one end of the suction pipe extends into the sewage treatment tank and connects with the water inlet of the sewage rotating cylinder. A pump is provided on the top, the bottom opening of the sewage treatment tank is connected to one end of a circulation pipe, and the other end of the circulation pipe is connected to the side opening of the sewage treatment tank, and a circulation pump is provided on the circulation pipe. A water outlet is provided below the side of the treatment tank, and a drain pipe is connected to the water outlet, and a drain valve is provided on the drain pipe. Although this invention has a simple structure, it has many shortcomings and defects. , the design of the second motor has defects. When in use, the second motor drives the stirring shaft to stir the bottom of the sewage treatment tank, which increases the use cost and energy consumption. Insufficient, the use of pulling to clean the disinfection filter plate reduces the overall sealing performance of the sewage treatment tank, and the sewage easily penetrates outward through the gaps of the disinfection filter plate, reducing the service life of the sewage treatment tank. In view of these situations, for To avoid the above-mentioned technical problems, it is necessary to provide a novel circulating sewage treatment tank to overcome the defects in the prior art
