Thin type ultra-fine rotating grating trash remover

Abstract

The invention discloses a thin type ultra-fine rotating grating trash remover. A machine frame is arranged in a water channel in an inclined mode. Filter plates are arranged between a left chain and a right chain. A driving motor drives a main chain wheel to drive the filter plates to rotate along rails through the left chain and the right chain so that sewage can be lifted to the upper portion of a machine frame from the upstream face of the water channel and slag can fall. The width of the filter plates is at least two times the length of each chain link of the chains. According to the thin type ultra-fine rotating grating trash remover, displacement, in the front and back direction, generated when the links rotate is compensated for through open grooves, and therefore the main problem of applying the narrow-spacing chains to the rotating grating trash remover is solved. The diameter of the chain wheel corresponding to the narrow-spacing chains can be greatly reduced, the thickness of the trash remover is obviously reduced, manufacturing cost is directly reduced, the height of a baffle at the bottom of the water channel is reduced, the effective filtration area of the trash remover is enlarged, and filter efficiency is higher.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a thin ultra-fine rotating grid cleaning machine. Background technique [0002] Rotary grid cleaning machine is widely used in water intakes of sewage treatment plants, drinking water intakes, large-scale hydropower stations, comprehensive treatment projects of rivers and lakes, rainwater drainage and sewage lifting pump stations and other facilities. The waste is salvaged through the filter screen assembly and lifted out of the water surface. When the filter screen assembly rotates to the top and turns, the dirt is dumped into the dirt hopper; the water flow from the drain is filtered through the grille and then flows to the rear water purification area. The equipment disclosed in the applicant's invention patent "201110192178.7---reverse fishing grill cleaning machine" is as follows: figure 1 As shown, the equipment is installed in the water channel with a lar...

Problems solved by technology

[0006] The applicant aims at the large pitch of the above-mentioned existing grid cleaning machine, thick equipment, non-standard production of chains and sprockets, high cost and unstable operation. It leads to the disadvantages of reduced water flow, and provides a thin ultra-fine rotary grid cleaning machine with a reasonable structure, so that standard chains can be used to reduce the thickness of the equipment, and achieve a large water flow under the premise of ensuring the filtering effect.
