Ventilation backwash filtering screen system and cleaning method of ventilation filtering screen

Abstract

The invention discloses a ventilation backwash filtering screen system and a cleaning method of the ventilation filtering screen, and aims to provide a ventilation backwash filtering screen system with low use cost so as to solve the problem that the conventional ventilation filtering screen needs to be maintained manually and frequently after dust accumulation. With the system, the frequency of cleaning and maintaining the ventilation filtering screen manually is greatly reduced. The ventilation backwash filtering screen system comprises a shell, a filtering screen installed on the shell, a motor, at least one rotation arm and hairbrush bars, wherein the motor is installed in the center of the filtering screen and the output shaft of the motor is perpendicular to the plane of the filtering screen; the at least one rotation arm is fixedly connected with the output shaft of the motor; the hairbrush bars are installed on the rotation arms; the brush surfaces of the hairbrush bars are in contact with the surface of the filtering screen, and the hairbrush bars extend outward from the middle of the filtering screen to the edge of the filtering screen. The ventilation backwash filtering screen system is simple in structure, is simple to use and maintain, and is low in cost; the ventilation backwash filtering screen system and the cleaning method of the ventilation filtering screen can be applied to various ventilation occasions, especially the occasions with high ventilation quality requirement.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment, in particular to a ventilation backwash filter screen system and a cleaning method for the ventilation filter screen. Background technique [0002] During the use of existing ventilation equipment, the filter screen at the inlet of the induced draft fan (supply fan) accumulates dust in a large volume, and long-term use will easily lead to a decrease in ventilation efficiency. Insufficient ventilation for a long time in the room will easily cause high temperature, resulting in equipment failure, and lead to polluted air. Moreover, the existing filter screen is not easy to clean during the ventilation process, and needs to be shut down for removal and cleaning. In the case of high ventilation quality and efficiency, the filter screen cleaning frequency is high and the maintenance workload is heavy, resulting in high maintenance costs for the filter screen. No more. Contents of the ...
