Industrial wastewater filtering and desilting device

Abstract

An industrial wastewater filtering and desilting device comprises: a treatment tank, a water inlet pipe, a first supporting plate, a power device, a second sliding plate, a first rotating shaft, a filtering plate, a third supporting plate, a third sliding plate, a flow guide table, a sludge guide plate and a sludge tank; wherein the top of the drainage chamber is closed, and a water outlet pipe and an emptying pipe are arranged on the right side of the drainage chamber; the first supporting plate is arranged on the treatment pond, a lifting assembly is arranged on the right side face of the first supporting plate, and the power device is arranged on the lifting assembly; the first rotating shaft is rotationally connected with the second sliding plate; the multiple sets of third supporting plates are arranged on the first rotating shaft; the third sliding plate is slidably arranged on the third supporting plate; the sludge guide plate is obliquely arranged at the front end of the treatment tank; and the sludge tank is arranged at the front end of the treatment tank. According to the invention, sludge scraping operation can be performed on the surface of the filter plate continuously, so that the foreign matters are prevented from adhering to the filter plate, a power device does not need to be started in the sludge scraping process, energy is saved, and sludge treatment is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an industrial wastewater filtering and desilting device. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process that are lost with water. Wastewater needs to be filtered to remove large impurities and foreign matter. After filtration, sedimentation mud is formed, and then the sedimentation sludge in the water body is removed through the desilter device, so as to achieve the purpose of reducing the solid content of the wastewater and purifying the water body. The filter screen of the existing filter and desilter device is easily blocked by impurities and foreign matter, which affects the...

AI Technical Summary

Problems solved by technology

The filter screen of the existing filter and desilter device is easily blocked by impurities and foreign matter, which affects the efficiency of industrial wastewater filtration, and the precipitated sludge is not easy to remove. Usually, the desilting process needs to be carried out manually, which takes a long time and is labor-intensive. mud cost high
