TECHNICAL FIELD
[0001] The utility model relates to the technical field of bag type dust collector, especially to a bag type dust collector with anti-explosion structure. BACKGROUND
[0002] The bag type dust collector, commonly known as the bag type dust collector, is a device widely used in the field of industrial dust removal. The working principle of the bag type dust collector is based on the filtration of dust-containing gas by filter material. When the gas enters the filter chamber, the dust particles are intercepted by the fibers of the filter cloth due to the inertial force when they pass through the fibers. The fine dust particles are separated from the fibers due to the small gap between the fibers being smaller than the free path of the gas molecule Brownian motion. The purified air is discharged from the air outlet.
[0003] The existing filter bag dust collector does not have a device for automatically cleaning the dust attached to the filter bag, which is inconvenient to use. Even though some existing filter bag dust collectors have a device for automatically cleaning the dust on the filter bag, they only blow air from the inside of the filter bag to the outside through the principle of air backwashing, causing the dust to fall off the filter bag, which has poor cleaning effect.
[0004] The existing patent (publication number: CN219897412U) discloses a bag type dust collector, which includes a bottom plate, a support, a gas tank, an air inlet pipe, an air outlet pipe, a cylinder and a filter cloth. The gas tank is fixedly installed on the upper end of the bottom plate through the support, and a cavity is arranged in the gas tank. The air inlet pipe and the air outlet pipe are installed on the upper and lower parts of the gas tank respectively, and valves are arranged on the air inlet pipe and the air outlet pipe. The air inlet pipe and the air outlet pipe are in communication with the cavity of the gas tank. The cylinder is provided with a cavity, and a plurality of filter holes communicating with the cavity are arranged on the cylinder. It can automatically clean the dust on the filter cloth, and has good cleaning effect, convenient use and high practicability.
[0005] To solve the above problems, the existing patent provides a scheme that can automatically clean the dust on the filter cloth, and has good cleaning effect and convenient use. However, since the dust is in contact with the internal cloth bag, friction is easy to occur, which may cause static electricity and increase the risk of explosion of the dust collector, thus reducing the safety.
