Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically a self-cleaning dust collector filter bag. Background Technology

[0002] Dust collector filter bags are a type of high-efficiency dust collection filter material, mainly used in baghouse dust collectors. They purify the air by filtering dust-laden gas. Dust collector filter bags are usually made of materials such as polyester staple fiber, PPS fiber, PP polypropylene, aramid fiber, and nylon fiber, and have the characteristics of good air permeability, high dust collection rate, and easy dust removal.

[0003] The "Automatic Cleaning Dust Collector Filter Bag" disclosed in application number "202323304082.2" includes a filter chamber, an installation ring fixedly fitted on the outer peripheral wall of the filter chamber, an installation plate placed inside the filter chamber, four filter screens embedded in the outer peripheral wall of the filter chamber, and a movable plate placed inside the filter chamber. A brush layer is fixedly fitted on the outer peripheral wall of the movable plate. This automatic cleaning dust collector filter bag facilitates cleaning of the filter screens through the action of the brush layer, making it convenient for operators to use. The threaded connection between the screw and the movable plate allows for easy movement of the movable plate, facilitating operation. Furthermore, the clearance fit between the fixing rod and the fixing hole allows for convenient installation of the installation plate, making it even more convenient and practical.

[0004] However, the above method still has the following drawbacks: the moving plate is moved by the screw, which moves the brush layer and can clean the filter screen. However, the brush roller is located inside the filter chamber. After filtration, the dust will adhere to the outer surface of the filter screen, making it difficult to clean the dust on the outer surface of the filter screen. The cleaning quality of the dust is poor and it is easy to leave residue. Utility Model Content

When the protrusion of the cam 8 passes the support component 18, the retaining ring 17 and the washer 15 can be lifted by the support component 18. The washer 15 can compress the spring 19. When the protrusion of the cam 8 leaves the support component 18, the spring 19 can push the washer 15 to quickly return to its original position, thereby realizing the reciprocating motion of the washer 15. When the washer 15 reciprocates, it can continuously beat the filter bag body 1, which can make the filter bag body 1 vibrate.

[0027] In this embodiment, preferably, a support 11 is welded to the middle of the top of the mounting plate 10. The support 11 is rotatably connected to the support shaft 12 through a bearing. The cam 8 is welded to the support shaft 12. The drive assembly 9 includes a motor 901, a driven wheel 903, and a V-belt 904. The motor 901 is fixedly connected to the bottom of the mounting plate 10. The output shaft of the motor 901 is fixedly connected to the drive wheel 902. The driven wheel 903 is connected to the drive wheel 902 through the V-belt 904. The middle of one side of the driven wheel 903 is fixedly connected to one end of the support shaft 12. The drive wheel 902 is driven by the motor 901. The drive wheel 902 can drive the driven wheel 903 to rotate through the V-belt 904, which in turn can make the cam 8 rotate quickly. A channel 13 is opened on the surface of the mounting plate 10. The V-belt 904 is located inside the channel 13. The channel 13 can ensure that the V-belt 904 contacts the mounting plate 10 when it moves.

[0028] In this embodiment, preferably, the support assembly 18 includes a support plate 1801 and a support roller 1803. The support plate 1801 is welded to the middle of the retaining ring 17. A roller seat 1802 is fixedly provided at the middle of the bottom end of the support plate 1801. The support roller 1803 is rotatably connected to the inside of the roller seat 1802. The cam 8 is slidably connected to the support roller 1803. When the cam 8 rotates, the retaining ring 17 can be supported by the support roller 1803 and the support plate 1801. The support roller 1803 can reduce the friction between itself and the cam 8 by rotating.

[0029] In this embodiment, preferably, the top of the filter bag body 1 is fixedly provided with an installation ring 2, and the installation ring 2 is engaged with the inside of the pressure ring 3. By fastening the pressure ring 3 onto the installation ring 2, the filter bag body 1 can be limited. A steel ring 5 is welded to the inner wall of the pressure ring 3, and the bottom of the steel ring 5 is welded to the top of the upright 6. Several installation holes 4 are opened on the surface of the pressure ring 3, and the pressure ring 3 can be fixedly installed through the installation holes 4.

[0030] In this embodiment, preferably, the surface of the support ring 7 is provided with a first groove 14 that is slidably connected to the slide rod 16, the spring 19 is located between the support ring 7 and the washer 15, and the surface of the retaining ring 17 is provided with a second groove 21 that is slidably connected to the slide rod 16. The first groove 14 and the second groove 21 can guide the slide rod 16, and the slide rod 16 can support and guide the washer 15, thus maintaining the stability of the washer 15. A screw 20 is fixedly provided at the top of the slide rod 16, and a limit nut is threadedly connected to the screw 20. The limit nut is located at the top of the retaining ring 17. The top of the slide rod 16 can be limited by the limit nut and the screw 20, thus preventing the slide rod 16 from falling off.

[0031] When in use, the operator first installs the filter bag body 1 at the installation port of the dust collector. The installation ring 2 can limit the filter bag body 1. Then, the washer 15 is placed inside the filter bag body 1. The washer 15, the retaining ring 17 and the upright 6 can support the inside of the filter bag body 1 and prevent the filter bag body 1 from collapsing. Then, the pressure ring 3 is fastened on the installation ring 2 and the pressure ring 3 is fixed with bolts to complete the installation of the filter bag body 1. The filter bag body 1 can filter the dust in the airflow.

[0032] When it is necessary to clean the dust on the outer surface of the filter bag body 1, the operator drives the drive wheel 902 through the motor 901 of the drive assembly 9. The drive wheel 902 drives the driven wheel 903 to rotate through the V-belt 904, which in turn causes the cam 8 to rotate quickly. When the protruding part of the cam 8 passes the support roller 1803 of the support assembly 18, the support roller 1803 can lift the retaining ring 17 and the washer 15. The washer 15 can compress the spring 19. When the protruding part of the cam 8 leaves the support assembly 18, the spring 19 can push the washer 15 to quickly return to its original position, thereby realizing the reciprocating motion of the washer 15. When the washer 15 reciprocates, it can continuously beat the filter bag body 1, which can keep the filter bag body 1 in a vibrating state, thus shaking off the dust on the outer surface of the filter bag body 1 and making it less likely to produce dust residue. During this process, the support roller 1803 can rotate, which can reduce the friction between it and the cam 8 and make it less likely to cause wear.

[0033] When maintenance is required on the drive assembly 9 and the support assembly 18, the operator loosens the limiting nut of the fixed slide bar 16, removes the slide bar 16 from the retaining ring 17 and the support ring 7, and the washer 15 and the retaining ring 17 are separated from the support ring 7, which facilitates the maintenance of the drive assembly 9 and the support assembly 18.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
