Sewage filtering device

Abstract

The invention discloses a sewage filtering device which comprises a positioning mechanism and a filtering mechanism, the positioning mechanism comprises a rectangular frame, limiting strips, sliding rods, reset springs, contacts and a first magnet, the upper end and the lower end of the inner side of the rectangular frame are each provided with an arc-shaped face, and the two arc-shaped faces arelocated on a circle with the middle point in the rectangular frame as the circle center; and the limiting strips are arranged at the left ends of the arc-shaped faces, sliding grooves are evenly formed in the sides, close to the arc-shaped faces, of the limiting strips, sliding rods are arranged in the sliding grooves in a sliding mode, and reset springs are arranged between the sliding rods and one ends of the sliding grooves. When an overturning plate overturns, the overturning plate pulls a hinge block to move, then one end of a swing rod moves, and a balance weight ball at the other end ofthe swing rod generates hysteresis, so that a rubber column on one side of the swing rod is separated from a filter screen, then the rubber column strikes the filter screen, the filter screen vibrates, and impurities attached to the filter screen are vibrated off.

Description

technical field [0001] The invention relates to the technical field of filtering devices, in particular to a sewage filtering device. Background technique [0002] In the prior art, the sewage filtering device usually uses a filter to filter the dirt, but after a long period of use, the dirt will accumulate and remain on the filter, and as the amount of filtered sewage increases, the dirt will block part of the filter The filter holes cause the filter screen to filter sewage only through the remaining unblocked filter holes, which greatly reduces the filtration efficiency of the sewage filter device. Contents of the invention [0003] The object of the present invention is to provide a sewage filtering device to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a sewage filtering device, including a positioning mechanism, a filtering mecha...
