Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, in particular to municipal sewage grid filtration equipment. Background Art

[0002] Sewage is produced through a series of human activities such as human production and life. It is widely found in rural and urban sewers, industrial sewage ditches and other places. If sewage is discharged directly into nature without treatment, it will cause damage to the natural environment and pollution of water resources for people's lives. It will affect people's production and life at the least and people's health at the worst. Therefore, it is an inevitable choice for social progress to treat sewage before discharge. In the process of sewage discharge, garbage will enter the sewer along with the discharge of sewage. If the garbage in the sewer is not cleaned in time, it will cause sewer blockage over time, and then cause the paralysis of the urban sewer system, affecting people's production and life. For the cleaning of garbage in the sewer, grille baffles are usually used to filter the sewage, and then the garbage in it is intercepted, and then the intercepted garbage is picked up and transported away by a conveying device. However, due to the impact of water flow, garbage will be stuck in the gap between the grille baffles, especially the garbage at the back of the grille baffle gap. When grabbing the garbage, it is directly pushed through the grille baffle, affecting its filtration quality. For this reason, we propose a municipal sewage grille filtration equipment.
