DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Embodiment:

[0025] Referring to Figures 1-4 , a pulse bag filter includes a dust collector body 1. A plurality of groups of bag cages 2 are connected inside the dust collector body 1. Dust removal bags are sleeved on the bag cages 2. A plurality of pulse generators 4 for pulse dust removal are arranged inside the dust collector body 1. It further includes: a chassis 201, arranged at the bottom of the bag cage 2, and the chassis 201 is used to block the bottom of the bag cage 2 to prevent the leakage of air flow and dust; a support rod 203, fixedly connected to the chassis 201, a sliding ring 204 is slidably connected to the support rod 203, and a plurality of groups of brush hairs 205 for cleaning the inner walls of the bag cage 2 and the dust removal bag are installed on the sliding ring 204; a pull rope 302, fixedly connected to the sliding ring 204, one end of the pull rope 302 is located outside the dust collector body 1. By pulling the pull rope 302, the sliding ring 204 can slide on the support rod 203, and then the inner walls of the bag cage 2 and the dust removal bag are cleaned by the brush hairs 205. A plurality of groups of motors 3 are fixedly connected to the dust collector body 1, and a wire winding shaft 301 is fixedly connected to the output end of the motor 3. A plurality of groups of pull ropes 302 are all wound and connected to the wire winding shaft 301, and the pull ropes 302 can be stored by the wire winding shaft 301. A telescopic rod 501 is fixedly connected inside the dust collector body 1, and a movable bracket 502 is fixedly connected to the telescopic end of the telescopic rod 501. The movable bracket 502 is fixedly connected to the chassis 201. By the telescopic movement of the telescopic rod 501, the chassis 201 can be controlled to enter and move away from the bottom of the bag cage 2. A conical seat 202 is arranged on the chassis 201, and the support rod 203 is fixedly connected to the conical seat 202. The top of the bag cage 2 is arranged in a gradually shrinking cone shape, and the diameter of the sliding ring 204 is larger than the diameter of the small end of the cone at the top of the bag cage 2. An installation frame 101 is fixedly connected inside the dust collector body 1, and the telescopic rod 501 is fixedly connected to the installation frame 101.

[0026] When this device is in use, put the cloth bag on the cage 2, and then introduce the gas to be treated through the air inlet of the dust collector body 1. At this time, the gas will pass through each cage 2, and after being dust-removed and filtered by the cloth bag, it will finally be discharged through the air outlet end of the dust collector body 1. After using it for a period of time, a lot of dust will accumulate in the cloth bag and the cage 2. At this time, start the motor 3, pull the pull rope 302 through the wire reel 301, so that the sliding ring 204 moves up continuously, and finally reaches the conical end at the top of the cage 2. Since the positions of each cage 2 are different, the lengths of each pull rope 302 are different, but it is necessary to ensure that when the wire reel 301 rotates to a stop, the sliding rings 204 on each pull rope 302 are as close as possible to the top of the cage 2 for synchronous dust removal, and then reset to make the sliding ring 204 return to its initial position.

[0027] Then start the pulse generator 4, and then remove the dust from the cage 2 and the cloth bag sleeved on the cage 2. Some dust will fall into the lower chassis 201. Finally, start the telescopic rod 501, and separate the chassis 201 from the cage 2 through the mounting bracket 101, and then the dust can be discharged.

[0028] It should be noted that when starting the pulse generator 4, the sliding ring 204 should be at the bottom, not at the top, otherwise it will affect the effect of pulse dust cleaning.

[0029] Through the setting of the sliding ring 204 and the brush hair 205, before pulse dust removal, the inner walls of the cage 2 and the cloth bag can be pre-cleaned by the brush hair 205 to remove some larger dust particles, and the progress of dust removal will not be affected during this process, which is convenient for use.

[0030] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
