[0002] Bag dust collector is a very common dust removal equipment in industrial production process. The bag dust collector sends dust-laden air into the dust collector box through the air inlet pipe. The dust-laden air passes through the bag, and the dust in it is filtered by the bag and falls into the ash hopper for collection. The filtered air is discharged into the atmosphere.

[0003] However, the existing bag dust collector lacks a mechanism for clearing the filter bags when filtering and removing smoke, so that during the filtering and dust removal process, the filter holes of the filter bags will gradually be blocked by dust particles in the smoke. Therefore, it is necessary to frequently stop the bag dust collector to clear the filter bags, thereby reducing the efficiency of filtering and removing smoke. In view of this, the present utility model is specially proposed. Utility Model Content

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0021] Example 1:

[0022] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The bag dust collector includes a tank body 1, a support plate 2 is fixedly connected to the tank body 1, a plug-in slot is provided on the support plate 2, a filter bag 202 is plugged into the plug-in slot, the filter bag 202 is detachably connected to the support plate 2, and an air inlet pipe 101 and an air outlet pipe 102 are fixedly connected to the tank body 1. It also includes: a cover plate 5 detachably connected to the tank body 1; a lifting plate 3, which can be lifted and connected to the cover plate 5; a rotating shaft 302, which is set in the filter bag 202, wherein one end of the rotating shaft 302 passes through the cover plate 5 and is rotatably connected to the lifting plate On the drop plate 3, one end of the rotating shaft 302 located in the filter bag 202 is fixedly connected to the air nozzle 304, and the axis of the rotating shaft 302 is provided with a hollow cavity 303 connected to the air nozzle 304; the rotary joint 307 is arranged on the rotating shaft 302 and is connected to the hollow cavity 303; the booster pump 305 is fixedly installed on the cover plate 5, and the output end of the booster pump 305 is connected to the rotary joint 307 through the pipe 306; the driving part is arranged on the cover plate 5 and is used to drive the rotating shaft 302 to rotate.

[0023] The driving part includes an impeller 4 , which is fixedly mounted on one end of the rotating shaft 302 passing through the pipe 306 , and the pipe 306 is fixedly connected to the lifting plate 3 .

[0024] The electric telescopic rod 301 is symmetrically fixedly mounted on the cover plate 5 , and the lifting plate 3 is fixedly connected to the output end of the electric telescopic rod 301 .

[0025] During use, the smoke-containing gas is introduced into the tank body 1 through the air inlet pipe 101. When the smoke drifts upward in the tank body 1 and passes through the filter bag 202, the dust particles carried by the smoke are blocked on the outer surface of the filter bag 202, while some larger dust particles fall to the bottom of the tank body 1 under the action of their own weight, thereby filtering and removing the smoke. The filtered and dust-removed gas is then discharged from the tank body 1 through the air outlet pipe 102. Both the air inlet pipe 101 and the air outlet pipe 102 are provided with a one-way valve.

[0026] When filtering and removing smoke and dust, the booster pump 305 and the electric telescopic rod 301 are started, and the booster pump 305 absorbs external air, and then the absorbed air is sequentially transported through the pipe 306 and the hollow cavity 303 into the air nozzle 304 for ejection, thereby back-cleaning the dust particles adsorbed on the outer wall of the filter bag 202, thereby achieving the purpose of unblocking the filter holes of the filter bag 202. At the same time, the electric telescopic rod 301 drives the lifting plate 3 to drive the rotating shaft 302 and the air nozzle 304 to reciprocate up and down, thereby causing the air nozzle 304 to spray The outgoing gas can reversely clean the filter holes at different positions of the filter bag 202. At the same time, when the gas passes through the pipe 306, the gas drives the rotating shaft 302 to rotate through the impeller 4, and the rotating shaft 302 drives the air nozzle 304 to rotate synchronously, so that the air nozzle 304 that reciprocates up and down can fully reverse clean the filter holes at different positions of the filter bag 202, thereby ensuring that the filter bag 202 always remains unobstructed during the smoke filtering and dust removal, preventing the filter bag 202 from being blocked and reducing the efficiency of the smoke filtering and dust removal.

[0027] It should be noted that the pipe 306 is a stretchable and shrinkable hose, so the pipe 306 will not interfere with the up and down reciprocating motion of the lifting plate 3;

[0028] It should be noted that an activated carbon filter (not shown in the figure) is provided at the input end of the booster pump 305, so that when the external gas passes through the input end of the booster pump 305, it comes into contact with the activated carbon filter. Since the activated carbon has a developed void structure and rich microporous tissue inside, these microporous tissues have a strong adsorption force field. When the gas comes into contact with the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb particulate matter in the air into the micropores, thereby achieving the effect of purifying the gas and preventing the particulate impurities carried in the gas from clogging the air nozzle 304 when the gas is ejected through the air nozzle 304.

[0029] Example 2:

[0030] Reference Figure 1, a bag dust collector is basically the same as that of Example 1, and furthermore, the bottom of the tank body 1 is set in a cone shape, and the bottom of the tank body 1 is fixedly connected to a dust exhaust pipe 103, and a valve switch is provided on the dust exhaust pipe 103; when it is necessary to clean the dust particles blocked in the tank body 1, first open the valve switch on the dust exhaust pipe 103, and then the dust particles can be discharged from the tank body 1 through the dust exhaust pipe 103. Since the bottom of the tank body 1 is set in a cone shape, it helps the dust particles to be discharged from the tank body 1 through the dust exhaust pipe 103, thereby improving the cleaning effect of the dust particles blocked in the tank body 1.

[0031] Example 3:

[0032] Reference Figure 1 、 Figure 2 , the bag dust collector is basically the same as that of Example 1. Furthermore, the support plate 2 is detachably connected with a support ring 201 by a fixing bolt 203. The support ring 201 is fixedly connected to the upper end of the filter bag 202, and the support ring 201 is communicated with the filter bag 202. The setting of the fixing bolt 203 makes it easy to fix the filter bag 202 to the support plate 2 through the cooperation of the support ring 201 and the fixing bolt 203. At the same time, it is also convenient for the staff to remove the filter bag 202 from the support plate 2 with the help of tools. Therefore, when the filter bag 202 needs to be replaced, it is convenient for the staff to disassemble and replace the filter bag 202.

[0033] A collar 204 is fixedly connected to the support ring 201, and a sealing sleeve 205 is provided on the collar 204, which fits the groove wall of the plug-in groove; after the installation of the filter bag 202 is completed, the collar 204 inserted in the plug-in groove squeezes the sealing sleeve 205 to fit tightly with the groove wall of the plug-in groove, thereby increasing the sealing performance of the connection between the support ring 201 and the support plate 2, preventing smoke from leaking through the gap between the support ring 201 and the support plate 2 through the plug-in groove without being filtered by the filter bag 202, thereby ensuring that the smoke can be fully filtered by the filter bag 202 and improving the filtering effect of the smoke.

When the cover plate 5 is fixedly installed on the tank body 1, the sealing gasket 502 fits with the top surface of the tank body 1, thereby achieving the purpose of increasing the sealing of the connection between the cover plate 5 and the tank body 1, thereby improving the sealing of the tank body 1.
