Mode of removing dust by vibrating filter screen in beating manner with aid of reverse blowing

Abstract

The invention relates to a mode of removing dust by vibrating a filter screen in a beating manner with the aid of reverse blowing. A stainless steel filter screen, a supporting rack, a metal beating net, a cam, a motor, an electrical control unit and a fan are used. In the beating and vibrating mode, the motor, the supporting rack, the cam and the beating net are mainly used, the motor drives thecam to act on the supporting rack, and the supporting rack drives the beating net to vibrate and beat the filter screen. Reverse blowing only has an assisting effect, and a filter screen vibrating dust removal mode with a reverse blowing function is not added in requirements of the patent. The reverse blowing function is fulfilled in an assisted manner, and is characterized in that the electricalcontrol unit is additionally provided with a frequency converter to realize reverse rotation of the fan, and thus, air is blown outwards from the inside of the equipment. In the vibrating and beatingprocess, dust on a filtering net plate loosens and then drops in the equipment.

Description

technical field [0001] The invention relates to a dust removal method in which a flapping vibrating filter net is supplemented with back blowing. Background technique [0002] The filter dust removal of refrigeration, heating, ventilation and other equipment is very important for the normal use of the equipment. In long-term use, dust will adhere to the filter of the equipment, resulting in poor air return of the equipment, resulting in a decrease in the air volume at the air outlet, which directly affects the cooling capacity, heating capacity, fresh air volume, and exhaust air volume of the equipment, and the equipment cannot function as preset. ability, the expected effect cannot be achieved. Severe blockage of the filter screen will cause the fan to overheat and even be damaged. Therefore, regular cleaning of the filter screen is a time-consuming and laborious daily work. However, due to the installation height of the equipment or the built-in installation of the equi...

AI Technical Summary

Problems solved by technology

In long-term use, dust will adhere to the filter of the equipment, resulting in poor air return of the equipment, resulting in a decrease in the air volume at the air outlet, which directly affects the cooling capacity, heating capacity, fresh air volume, and exhaust air volume of the equipment, and the equipment cannot function as preset. capacity, not as expected

Severe blockage of the filter screen will cause the fan to overheat until it is damaged

Therefore, regular cleaning of the filter screen is a time-consuming and laborious daily work.

However, due to the installation height of the equipment or the built-in installation of the equipment, etc., it is difficult to clean the filter screen, and the cost of labor and facilities is high. Some also involve high-altitude operations, which will cause safety problems for the workers who clean the filter screen.
