Abstract

A dust filtering apparatus is characterized by comprising a gas inlet, a gas outlet, a tank provided with a dust outlet, and a filtering structure arranged in the tank. The filtering structure comprises a plurality of annular skeletons with increasing diameters, the annular skeleton with a smaller diameter is arranged in the annular skeleton with a bigger diameter, the cross section of each annular skeleton is in a U shape, the wall of each annular skeleton is provided with a plurality of through holes; annular sealing plates are arranged between the upper openings of annular skeletons, and the upper opening of the biggest annular skeleton and the tank; filter cloth is paved on the external lateral wall of each annular skeleton, the gas outlet is arranged in the top part of the tank, the gas inlet is arranged in the lower part of the tank, the dust outlet provided with a valve is arranged in the bottom of the tank, and the gas outlet is connected to an exhaust fan through a pipeline. Compared with the prior art, the provided dust filtering apparatus has the advantages that the air filtration capacity is large and the filter material cannot be destroyed easily.

Description

[0001] Technical field: [0002] The invention relates to an air filter. [0003] Background technique: [0004] The existing technology of filtering dust in the air through filter materials is generally the filter bag technology, and the air flow of the filter bag will be affected due to the deformation of the filter bag under the action of wind pressure, and it is also easy to be damaged. [0005] Invention content: [0006] The object of the present invention is to provide a dust filter with a large air filtration capacity and a filter material that is not easily damaged. [0007] The present invention is achieved in this way, including a tank body with a gas inlet, a gas outlet, and a dust outlet, and a filter structure arranged in the tank body. The filter structure includes several circular skeletons with diameters ranging from small to small. The frame is located in the large-diameter circular frame. The cross-section of the circular frame is U-shaped. There are severa...
