Abstract

The invention provides a self-cleaning air filter.A plurality of filter elements and pressure sensors are installed in a shell, and an air outlet is formed in the rear end of the shell.An air inlet box is arranged on the lower portion of the shell, an air inlet is formed in the front end of the air inlet box, and a compressed air pipe and a dirt discharging pipe are arranged in the air inlet box.A plurality of rotary suction nozzles are arranged in each filter element and are communicated with a perpendicularly-downward suction pipe, the lower end of each suction pipe is connected to a suction device, and a venturi water spray nozzle is arranged at the tail end of the dirt discharging pipe.By means of the self-cleaning air filter, the efficiency of air filtering equipment can be greatly improved, clean air production cost can be reduced, and energy can be saved; equipment running is more reliable, and the service life of the high-strength filter elements is longer; no dust is accumulated and stored in the equipment; the maintaining work of the filter is simplified, and daily maintenance workload is greatly reduced; the occupied area is small, and investment is small; economic and social benefits are very remarkable.

Description

technical field [0001] The invention relates to a self-cleaning air filter, which is applied to various occasions where air needs to be filtered. Background technique [0002] Air filters are widely used in modern society and are applicable to various fields of national economy and people's life: improving the quality of fluids such as water and air, improving the recycling level of resources such as water and oil, and treating discharged sewage, etc. [0003] There are many kinds of air filters currently in use. The general division method is: primary filter, medium filter and high efficiency filter, which play an important role in all walks of life. The primary air filter is suitable for primary filtration of air conditioning systems, compressed air systems and clean air supply systems, filtering dust particles above 5 μm. The medium-efficiency air filter is mainly used to protect the high-efficiency air filter and filter dust particles with a particle size of 0.5-5um. H...
