Description

Technical Field

[0001] The utility model relates to the technical field of mud scrapers for sewage treatment, in particular to a mud scraper for sewage treatment with a flow grid. Background Art

[0002] In the sewage treatment process, the flow screen first intercepts and filters the solid impurities in the sewage to prevent them from entering the subsequent treatment equipment. Then, the scraper cleans the sludge produced after filtration to ensure the normal operation of the sewage treatment equipment. This equipment has broad application prospects in sewage treatment plants and urban water supply and drainage systems. It can improve sewage treatment efficiency, reduce maintenance costs, and help protect the environment.

[0003] The grating in the prior art is generally fixed and horizontally installed on the top surface of the filter tank, so that the sludge cannot be piled up high on the grating. If it is piled up high, it will easily lead to poor filtration effect or cause blockage. Therefore, the sludge scraping cycle is short and the sludge is scraped repeatedly frequently, thereby affecting the filtration efficiency. Therefore, a sludge scraper for sewage treatment with a flow grating is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a scraper for sewage treatment with a flow grid to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sludge scraper for sewage treatment with a flow grid, comprising a water pool, a grid and a scraper, a filter screen is arranged at the lower end of the grid, and the grid and the filter screen are connected with a connecting rod;

[0006] A slide groove is provided on the inner wall on both sides of one end of the water pool, and the slide groove is arc-shaped. Slide blocks are fixedly installed on both sides of the other end of the filter screen, and the slide blocks are arranged inside the slide groove;

[0007] A first rotating motor is installed on the surface of one side of the water pool, and an output end of the first rotating motor penetrates through the surface of the water pool and is connected to a gear, and the gear is arranged inside the water pool;

[0008] An arc-shaped rack is meshed with each other on one side of the gear, and one side of the arc-shaped rack is fixedly mounted on the side surface of one end of the filter screen.

[0009] Furthermore, the scraper is sleeved on the outer side of the grille, and threaded rods are provided through both ends of the scraper, and the other end of the threaded rod is connected to a second rotating motor.

[0010] Furthermore, one end of the threaded rod is mounted on one side of a fixed plate, and the output end of the second rotating motor passes through a set of fixed plates and is connected to the other end of the threaded rod.

[0011] Furthermore, mounting rods are fixedly mounted on both sides of one end of the filter screen, and the mounting rods are mounted on the inner walls of both sides of the pool, and the mounting rods can rotate on the inner wall of the pool.

[0012] Furthermore, a baffle is installed on the inner wall of one end of the water pool, and one side of the baffle is set as a sludge tank.

[0013] Furthermore, a drain outlet is provided on one side of the water pool, and the drain outlet passes through the interior of the water pool.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Through the adjustable grille and filter, sewage will flow to the lower place by its own gravity, thereby driving the sludge to accumulate in the lower place, and the high place can be filtered normally, avoiding the problem that the grille in the prior art is generally fixedly installed horizontally on the top surface of the filter tank, which requires frequent and repeated scraping of mud and easily clogs the filter.

[0016] 2. The threaded rod is driven to rotate by the second rotating motor, and the rotation of the threaded rod can drive the scraper to move to one side. The scraper continuously moves, so that impurities and sludge on the surface of the grille and the filter can be scraped off into the sludge tank. Impurities and sludge on the surface of the grille and the filter can be scraped off at the same time, which greatly improves the filtration efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
