Description

Technical Field

[0001] The utility model relates to the field of environmental protection equipment, in particular to a two-stage inclined mesh grille dirt remover. Background Art

[0002] The existing mesh screen grating dirt removal machines are generally designed with a 70° tilt angle (the angle between the mesh screen and the horizontal plane is 70°). This design has a small number of mesh screens submerged in the water body, so the amount of water flowing through the mesh screens is small, and the amount of dirt removed is small. In addition, the mesh screens installed on the existing mesh screen grating machines have a stepped dirt interception surface after assembly, and the recessed areas of adjacent mesh screens are not easy to clean.

[0003] Chinese patent CN205340306U discloses an inclined perforated plate grille dirt remover. The patent designs a curved mesh plate to address the above-mentioned defects, so as to overcome the problem that the depressions of adjacent mesh plates are difficult to clean. However, this brings a new problem: when the curved mesh plate is scooping slag (when moving upward), some garbage easily slides off the curved surface and falls into the water again.

[0004] In addition, in response to the problem that the existing mesh grille sewage cleaner has a tilt angle of 70°, some patents use an angle adjustment structure to adjust the tilt angle of the mesh grille sewage cleaner. For example, Chinese patent CN111704181A discloses a grille sewage cleaner. In this patent, the angle of the sewage machine (sewage cleaner) frame is adjusted by setting an adjustment component. This method can adjust the tilt angle of the sewage machine, that is, adjust the number of mesh plates submerged in the water body, but there is a new problem. Since the sewage machine frame is generally linear, when the tilt angle of the sewage machine is adjusted, the part submerged in the water surface is more, and the part leaking out of the water surface is less, especially in the downward section of the mesh plate, the part leaking out of the water surface is even less (the height is lower), which will affect the cleaning mechanism of the mesh plate. Cleaning. Utility Model Content

[0005] The utility model aims to provide a two-stage inclined mesh grille dirt remover.

[0006] The innovation of the utility model lies in: the structural design of the application is ingenious, the two-stage inclined structure of the frame can not only increase the amount of sewage interception, but also ensure that the filter plate has sufficient height for cleaning when it goes down; the filter plate is arc-shaped, and a slag scoop plate is arranged at the lower edge of the filter plate. The upward section can prevent garbage from sliding, and the downward section is easy to clean.
