Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a self-cleaning pulse dust collector. Background Technique

[0002] In industrial production, a corresponding dust collector is required to remove the dust generated by processed products. To ensure that the dust removal side of the dust collector has the functions of self-cleaning and recycling, dust removal filter bags are mostly used to adsorb dust, and high-pressure pulse air flow is regularly injected into the dust removal bags. The expanded dust removal filter bags promote the detachment of impurities attached to their surfaces.

[0003] Traditional pulse dust collectors usually use a single pulse jetting method for dust cleaning, but it has poor effect on wet dust. When the dust contains moisture, this moisture is easy to condense on the surface of the filter bag, forming a caked dust layer that blocks the pores of the filter bag, making it difficult to remove the wet dust on the filter bag, resulting in filter bag blockage and a decrease in dust removal efficiency. Therefore, we propose a self-cleaning pulse dust collector. Content of the Utility Model

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: a self-cleaning pulse dust collector, comprising:

[0026] A dust collector housing 1, a perforated plate 8 is fixedly connected to the top of the dust collector housing 1, and a plurality of filter bags 9 are fixedly installed inside the perforated plate 8;

[0027] A filter bag cleaning structure, the filter bag cleaning structure is located on the dust collector housing 1;

[0028] The filter bag cleaning structure includes a threaded rod 3, a slide rod 14, a rack 13, a rotating shaft 11, a cleaning eccentric wheel 12, a gear 15 and a cleaning frame 10. The threaded rod 3 is rotatably connected inside the dust collector housing 1, and the top end of the threaded rod 3 rotatably extends outside the dust collector housing 1. The slide rod 14 is fixedly connected inside the dust collector housing 1. One end of the cleaning frame 10 is threadedly sleeved on the outer surface of the threaded rod 3, and the end of the cleaning frame 10 away from the threaded rod 3 is slidably connected to the slide rod 14. The rack 13 is fixedly connected to one side of the dust collector housing 1 close to the slide rod 14. The rotating shaft 11 is rotatably connected inside the cleaning frame 10. One end of the rotating shaft 11 rotatably penetrates through one side of the cleaning frame 10 and is fixedly connected to the gear 15. The gear 15 is meshed with the rack 13. The cleaning eccentric wheel 12 is fixedly connected to the outer surface of the rotating shaft 11.

[0029] The number of the filter bag cleaning structures is three. The three filter bag cleaning structures are installed in a linear array inside the dust collector housing 1. The top of the dust collector housing 1 is fixedly connected with a mounting plate 16. The top of the mounting plate 16 is fixedly installed with a driving motor 2. The output end of the driving motor 2 rotatably penetrates through the top of the mounting plate 16 and is fixedly connected to the corresponding threaded rod 3. Two synchronous belts 4 are respectively sleeved on the outer surfaces of the three threaded rods 3 in a driving manner. Both of the two synchronous belts 4 are located above the dust collector housing 1.

[0030] An air bag 6 and a solenoid valve 5 are respectively fixedly installed on one side of the dust collector housing 1. A blowpipe 7 is fixedly installed inside the dust collector housing 1. The bottom end of the blowpipe 7 corresponds to the corresponding dust filter bag 9. The air inlet end of the blowpipe 7 extends outside the dust collector housing 1. The solenoid valve 5 is fixedly installed on the blowpipe 7. An air inlet pipe is fixedly connected to one side of the dust collector housing 1. An air outlet pipe is fixedly connected to the side of the dust collector housing 1 away from the air inlet pipe. A dust collection hopper is fixedly connected to the bottom of the dust collector housing 1.

[0031] Furthermore, when using this device, the driving motor 2 is started by connecting an external power supply. The driving motor 2 can drive the corresponding threaded rod 3 to rotate. The rotation of the threaded rod 3 close to the driving motor 2 will, under the synchronous transmission of the two synchronous belts 4, enable the three threaded rods 3 to rotate synchronously. The rotation of the threaded rod 3 will drive the cleaning frame 10 to move under the guidance of the sliding rod 14. The movement of the cleaning frame 10 will drive the multiple cleaning eccentric wheels 12 inside it to move. Under the meshing connection of the gear 15 and the rack 13, when the cleaning frame 10 moves, the gear 15 will rotate under the meshing connection with the rack 13. The rotation of the gear 15 will drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 will drive the multiple cleaning eccentric wheels 12 thereon to rotate synchronously, thereby facilitating the multiple cleaning eccentric wheels 12 to strike the dust filter bags 9 on both sides of it, and further facilitating the cleaning of the dust on the dust filter bags 9. When the dust collector housing 1 is working, the dust-containing gas first enters the interior of the dust collector housing 1. Through the filtering action of the dust filter bags 9, the dust is blocked on the surface of the dust filter bags 9, while the clean gas passes through smoothly and is discharged. When the dust on the surface of the dust filter bags 9 accumulates to a certain extent, the pulse dust cleaning system starts to work, and the filter bags are pulse purged through the cooperation of the solenoid valve 5 and the air bag 6, and the dust is removed and falls into the ash hopper.

[0032] Through the cooperation of the threaded rod 3, the cleaning eccentric wheel 12, the rotating shaft 11, the cleaning frame 10, the gear 15, the rack 13 and the sliding rod 14, the threaded rod 3 will drive the cleaning frame 10 to move under the guidance of the sliding rod 14. Under the meshing connection of the gear 15 and the rack 13, when the cleaning frame 10 moves, the gear 15 will rotate under the meshing connection with the rack 13, and the rotating shaft 11 will drive the multiple cleaning eccentric wheels 12 thereon to strike the dust filter bag 9, thereby facilitating the cleaning of the dust on the dust filter bag 9, avoiding the difficulty of single cleaning to remove the wet dust on the dust filter bag 9, and further improving the dust removal efficiency of the dust filter bag 9.

[0033] Working principle: The driving motor 2 is started by connecting an external power supply. The driving motor 2 can drive the corresponding threaded rod 3 to rotate. The rotation of the threaded rod 3 close to the driving motor 2 will, under the synchronous transmission of the two synchronous belts 4, enable the three threaded rods 3 to rotate synchronously. The rotation of the threaded rod 3 will drive the cleaning frame 10 to move under the guidance of the sliding rod 14. The movement of the cleaning frame 10 will drive the multiple cleaning eccentric wheels 12 inside it to move. Under the meshing connection of the gear 15 and the rack 13, when the cleaning frame 10 moves, the gear 15 will rotate under the meshing connection with the rack 13. The rotation of the gear 15 will drive the rotating shaft 11 to rotate. The rotation of the rotating shaft 11 will drive the multiple cleaning eccentric wheels 12 thereon to rotate synchronously, thereby facilitating the multiple cleaning eccentric wheels 12 to strike the dust filter bags 9 on both sides of it, and further facilitating the cleaning of the dust on the dust filter bags 9.

[0034] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
