Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a flow guiding device for a bag type dust collector. Background Technique

[0002] A bag type dust collector is a dry dust filtering device. It is suitable for collecting fine, dry and non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the fiber fabric is used to filter the dust-containing gas. When the dust-containing gas enters the bag type dust collector, dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, and the gas is purified.

[0003] As disclosed in a kind of air inlet flow guiding device with the authorization publication number of CN207628112U, which includes a dust collector housing, filter bags, a conical housing and an air inlet pipe. A plurality of filter bags are arranged inside the dust collector housing. A conical housing is arranged at the lower part of the dust collector housing. An air inlet pipe is arranged on one side outside the conical housing. A trapezoidal main pipe is arranged inside the conical housing. The air inlet pipe is communicated with the main pipe. A plurality of flow guiding branch pipes extending upward are arranged on the upper surface of the main pipe. A plurality of baffles from low to high are arranged on the lower surface inside the main pipe. The baffles are respectively arranged corresponding to the upper and lower parts of the flow guiding branch pipes. The lower surface of the main pipe is set as a screen, and a collection chamber for particulate matter is arranged below the screen; the air flow of the utility model is evenly guided and the dust removal work is completed after being filtered by the filter bags, which greatly prolongs the service life of the filter bags. However, this utility model lacks effective flow guiding measures and is not convenient for the uniform dust removal effect when the dust-laden air enters the inside of the dust removal device. For this reason, we have proposed a flow guiding device for a bag type dust collector, which solves the flow guiding problem of this dust collector and improves the practicability and effectiveness of this device.
