Inclined plate sedimentation tank with bottom cavity sludge scraping function

Abstract

The invention provides an inclined plate sedimentation tank with bottom cavity sludge scraping function. The inclined plate sedimentation tank comprises a support plate, a hydraulic cylinder, a left guiding rod, a guiding groove, a water filter plate, a guiding tube, a plug, a rubber bag, a sludge cleaning plate, a sludge cleaning tank and a rubber pad, wherein the left side of a coarse filter chamber is connected with a semi-arc-shaped water inlet pipe opening, and the streamlined water filter plate with a filter hole structure is welded in the coarse filter chamber; a sludge scraping plate unique to the structure is installed on the bottom surface of a sedimentation chamber, and a row of brush and a scraper plate are installed at the front and the rear of the lower end of the sludge scraping plate, respectively. The bottom surface of the sedimentation chamber is first hardly cleaned by the scraper plate, and then the steel wire brush is used for fine cleaning; with the inclined chamber bottom structure, residual sludge at the bottom of the chamber is regularly cleaned up together, so as to prevent a large amount of residual sludge from forming at the bottom of the sedimentation chamber after long-term use; the structure is more reasonable.

Description

technical field [0001] The invention belongs to the technical field of sludge treatment structure at the bottom of an inclined plate sedimentation tank and aquaculture equipment, and more specifically relates to an inclined plate sedimentation tank with a bottom cavity scraping function. Background technique [0002] There is a very shallow sedimentation tank between every two parallel inclined plates in the inclined plate sedimentation tank. The treated water (or waste water) and the settled sludge move and separate from each other in the shallow sedimentation layer. Its overflow rate can reach 36nt3 / (rru"h). It is 7 to 10 times higher than the general sedimentation tank's buried capacity. [0003] The inventor found similar patents for tree injection in the process of searching for patents. For example, the application number is: CN201720699316.3, which relates to the field of sewage treatment technology and equipment, especially a new type of coagulation inclined plate s...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a sloping plate settling tank with a bottom chamber scraping function to solve the above-mentioned problem: the existing sloping plate settling tank has a single function, especially the sludge formed on the bottom surface, It will be removed through an external pipeline-type sludge discharge system, and after a long period of use, we will find that there will still be a large amount of residual sludge on the bottom of the pool
