Filtering apparatus capable of realizing falling of dust from filter screen

Abstract

The invention discloses a filtering apparatus capable of realizing falling of dust from a filter screen. The filtering apparatus comprises an apparatus shell; an air inlet and an air outlet are formed in the apparatus shell; a filter screen is arranged in the apparatus shell; the top of the filter screen is an air guide duct communicated with the air inlet; the bottom wall of the apparatus shell is provided with a dust-collecting box; a dust discharging chamber is arranged in the sidewall of the apparatus shell; an exhaust fan is fixedly arranged in the dust discharging chamber; a control chamber is also arranged in the sidewall of the apparatus shell; the side edge of the filter screen is located at the opening of the control chamber; a rotating motor is arranged in the control chamber; the main shaft of the rotating motor is uniformly and fixedly provided with elastic sheets; a beating ball is arranged on the end parts of the elastic sheets; and the top wall of the bottom wall of the control chamber are both fixedly provided with arc pressing blocks. The filtering apparatus provided by the invention is reasonable in structure, can guarantee the filtering effect of the filter screen, overcomes the technical shortcoming of influence on filtering effect due to proneness of filter screens to dust adsorption in the prior art, and has good usage stability and applicability.

Description

technical field [0001] The invention belongs to the technical field of filter equipment, and in particular relates to a filter device with dust falling from a filter net. Background technique [0002] With the maturity of various processing technologies in our country, various processing develops rapidly. In the production and processing process, waste gas and dust are relatively common processing pollutants. If they are directly discharged into the air, they will easily pollute the environment and affect human health. Therefore, the traditional technology mainly uses a filter device to filter the processing waste gas. It is mainly composed of a filter shell, an air inlet and an air outlet. There is a filter in the filter shell, and the dust is filtered out through the filter when in use. When the filter is used for a long time, it is easy to absorb more dust, which will affect the ventilation effect. Therefore, it is necessary to manually knock the filter regularly to make ...
