[0002] Bag filter is a dry dust filtering device, also known as bag filter or bag dust collector. It is suitable for capturing fine, dry, non-fibrous dust, and filtering dust-containing gas through the filtering effect of fiber fabric. When the dust-containing gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper, while the gas containing finer dust is retained when passing through the filter material, so that the gas is purified.
[0003] Since the dust is blocked when the gas containing finer dust passes through the filter bag, the dust will remain on the filter bag. However, as the use time increases, the surface of the filter bag will be covered with dust, which will reduce the dust filtering efficiency of the bag filter. In this way, the surface of the filter bag needs to be cleaned. During the cleaning process, the filter bag needs to be removed from the inside of the equipment. The disassembly and assembly process is very cumbersome. Therefore, in response to the above technical problems, a self-cleaning bag dust collector is proposed. Utility Model Content

A slide groove is provided on the upper side of the device body 1. 12, a slide plate 13 is fixedly connected to the lower side of the connecting strip 11, and the slide plate 13 and the slide slot 12 are slidably connected, a spring 14 is fixedly connected to one side of the slide plate 13, and the spring 14 is fixedly connected to the inside of the slide slot 12, a driving motor 15 is fixedly connected to the top of the inner side of the device body 1, a rotating shaft 16 is fixedly connected to the upper side of the driving motor 15, and the rotating shaft 16 and the device body 1 are rotatably connected, a butt plate 17 is fixedly connected to the outside of the rotating shaft 16, and the butt plate 17 is in contact with the pull rope 10.
[0025] An air inlet pipe 2 and an air outlet pipe 3 are fixedly connected to the outside of the device body 1, and the air inlet pipe 2 and the air outlet pipe 3 are installed on both sides of the device body 1. The installation height of the air outlet pipe 3 is much higher than the installation height of the air inlet pipe 2. The air inlet pipe 2 is designed below the air outlet pipe 3 so that the dust-containing gas can better contact the filter bag for dust removal.
[0026] A mounting plate 4 is fixedly connected to the inside of the device body 1, and a mounting block 6 is fixedly connected to the upper side of the mounting plate 4 and the inner top of the device body 1. The mounting block 6 and the filter bag 7 are fixedly connected, and the filter bag 7 has a certain elasticity. Since the filter bag 7 has a certain elasticity, it can be easily bent left and right to shake off dust.
[0027] Through holes 5 are provided on the upper side of the mounting plate 4 , and the through holes 5 are arranged in a plurality of groups in an array, so that dust can pass through the through holes 5 and then be discharged through the slag discharge pipe 18 .
