Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, and particularly relates to a pulse jet bag filter dust collector. Background Art

[0002] Pulse jet bag filter dust collectors are mainly used to remove dust generated in the industrial production process, help enterprises meet environmental protection emission standards, improve the working environment, and protect the health of workers. The dust-containing gas is filtered through filter bags, and the dust is intercepted on the surface of the filter bags. Then, the accumulated dust on the filter bags is removed by means of pulse jet, so that the filter bags can work continuously and effectively. In practical applications, pulse jet bag filter dust collectors usually require the following technologies:

[0003] 1. High-efficiency filter bag materials with good air permeability and filtration accuracy;

[0004] 2. Precise pulse jet control system to ensure the jet effect and dust cleaning efficiency;

[0005] 3. Reasonable air flow distribution structure to make the dust-containing gas pass through the filter bags evenly;

[0006] 4. Robust and durable box structure to withstand the pressure and vibration during operation;

[0007] 5. Reliable sealing device to prevent dust leakage.

[0008] Currently, in order to achieve effective dust removal, some manufacturers use small pulse jet bag filter dust collectors, which are suitable for small production sites and have a relatively simple structure.

[0009] For example, the Chinese patent discloses: a pulse jet bag filter dust collector, patent number: CN220918475U. The output shaft of the motor drives the first bevel gear to rotate through the second bevel gear, so that the first bevel gear drives the lead screw to rotate. The cleaning plate moves outside the filter bag, and the outer side of the filter bag is brushed by the brush to perform secondary cleaning on the filter bag, greatly improving the cleanliness of the filter bag and the use effect of the filter bag.

[0010] However, there is a prominent problem with the above method. The above device lacks an additional buffer function for the filter bags. When the dust collector starts, the relatively unstable air flow will pass through the filter bags that have not been fully extended and positioned. Without a buffer mechanism, after long-term operation, the filter bags are prone to tearing and damage, resulting in a decline in the filtering effect and exceeding the standard of dust emission. In response to this problem, this application proposes a solution to add an additional support buffer structure outside the filter bags, extending the service life of the filter bags and improving the stability and reliability of the dust collector. Summary of the Utility Model

[0011] (I) Technical Problems to be Solved

[0012] In view of the deficiencies of the prior art, the utility model provides a pulse jet bag filter, which solves the technical problems that the above device lacks the additional buffering function of the filter bag, and the relatively unstable air flow during the startup of the dust collector will pass through the filter bag that has not been fully extended and positioned, lacks a buffering mechanism, and after long-term operation, the filter bag is prone to tearing and damage, resulting in a decline in the filtering effect and excessive dust emissions.

[0013] (II) Technical solution

[0014] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0015] A pulse jet bag filter includes a filter bag body and a dust collector body. The filter bag body is sleeved inside the dust collector body. A first ring is fixedly connected to the outer surface of the filter bag body. A second ring is sleeved at the lower end of the first ring. Rectangular sleeve rings are fixedly connected to the outer surfaces of the first ring and the second ring. Sheathed rings are fixedly connected to the outer surfaces of the first ring and the second ring. The two sheathed rings are respectively sleeved inside the two rectangular sleeve rings. A buffer spring is fixedly connected inside the second ring. A support block is fixedly connected to the upper end of the buffer spring. The support block is in contact with the outer surface of the filter bag body. A support mechanism is sleeved inside the filter bag body. The support mechanism includes a tent ring, and the tent ring is sleeved inside the filter bag body.

[0016] Preferably: A top cover is fixedly connected to the upper end of the tent ring.

[0017] Preferably: Two clamping blocks are slidably connected inside the tent ring, and a pull ring is slidably connected inside the top cover.

[0018] Preferably: Inclined blocks are fixedly connected to the upper ends of the pull ring and the two clamping blocks.

[0019] Preferably: Return springs are fixedly connected to the outer surfaces of the pull ring and the two clamping blocks. An air jet blowing pipe is fixedly connected to one side of the dust collector body.

[0020] Preferably: An air inlet pipe is fixedly connected to one side of the dust collector body close to the air jet blowing pipe, and an exhaust pipe is fixedly connected to the side of the dust collector body far from the air jet blowing pipe.

[0021] (III) Beneficial effects

[0022] I. Before using the filter bag body, fix the first ring on the outside of the filter bag body by bonding. Socket the bottom of the filter bag body into the second ring and align the rectangular collar connected to the outside of the second ring with the inclined surface of the collar to be sleeved. At this time, hold the second ring and rotate it counterclockwise. The rectangular collar slides and sleeves on the outer surface of the collar to be sleeved. At this time, the bottom of the filter bag body has a certain degree of extensibility, providing additional support and buffering during the filtering operation, reducing the impact and vibration on the filter bag body during the operation, and reducing the risk of damage and deformation of the filter bag body, thereby extending its service life.

[0023] II. When placing and installing the filter bag body, hold and pull the pull ring towards the end close to the clamping block. During the sliding process of the pull ring, a set of inclined plane blocks squeeze another set of inclined plane blocks to slide away from the tent ring. At this time, insert the tent ring into the filter bag body. The upper end of the filter bag body is socketed in the top cover. Release the pull ring. Under the action of three return springs, the pull ring and the two clamping blocks are pulled back to their original positions. The two clamping blocks slide and clamp the outer surface of the filter bag body, ensuring the stability of the connection between the filter bag body and the tent ring through the clamping on both sides. And when performing the operation of removing the filter bag body for replacement and maintenance, pulling the top cover can drive the filter bag body to be pulled out. Pull the pull ring towards the end close to the clamping block, and the filter bag body loses the clamping force and quickly separates and falls off, which is beneficial to improving the stability of the filter bag body during placement and the convenience of replacement.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] In an embodiment of the present application, by providing a pulse-jet bag filter, the above-mentioned device is effectively solved. The lack of an additional buffering function for the filter bag means that relatively unstable air flow will pass through the filter bag that has not been fully extended and positioned when the dust collector starts. Without a buffering mechanism, after long-term operation, the filter bag is prone to tearing and damage, resulting in a decline in the filtering effect and excessive dust emissions. Before using the filter bag body, the first ring is fixed outside the filter bag body by bonding. The bottom of the filter bag body is sleeved inside the second ring, and the rectangular collar connected to the outside of the second ring is aligned with the inclined surface of the collar to be sleeved. At this time, hold the second ring and twist it counterclockwise. The rectangular collar slides and sleeves outside the collar to be sleeved. At this time, the bottom of the filter bag body has a certain degree of extensibility, providing additional support and buffering during the filtering operation, reducing the impact and vibration on the filter bag body during the working process, and reducing the risk of damage and deformation of the filter bag body, thereby extending its service life.

[0031] Embodiment

[0032] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the technical problems that the above-mentioned device lacks an additional buffering function for the filter bag, and the relatively unstable air flow during the startup of the dust collector will pass through the filter bag that has not been fully extended and positioned, lacking a buffering mechanism. After long-term operation, the filter bag is prone to tearing and damage, resulting in a decline in the filtering effect and excessive dust emissions. The general idea is as follows: A pulse jet bag filter includes a filter bag body 11 and a dust collector body 18. The filter bag body 11 is sleeved inside the dust collector body 18. A first ring 12 is fixedly connected to the outer surface of the filter bag body 11. A second ring 13 is sleeved at the lower end of the first ring 12. Rectangular sleeve rings 14 are fixedly connected to the outer surfaces of both the first ring 12 and the second ring 13. Sleeve rings 15 are fixedly connected to the outer surfaces of both the first ring 12 and the second ring 13. The two sleeve rings 15 are respectively sleeved inside the two rectangular sleeve rings 14. A buffer spring 16 is fixedly connected inside the second ring 13. The upper end of the buffer spring 16 is fixedly connected to a support block 17. The support block 17 is in contact with the outer surface of the filter bag body 11. Before the filter bag body 11 is used, the first ring 12 is fixed to the outer surface of the filter bag body 11 by bonding. The bottom of the filter bag body 11 is sleeved inside the second ring 13, and the rectangular sleeve ring 14 connected to the outside of the second ring 13 is aligned with the inclined surface of the sleeve ring 15. At this time, hold the second ring 13 and rotate it counterclockwise. The rectangular sleeve ring 14 slides and is sleeved on the outer surface of the sleeve ring 15 (the sleeve ring 15 is tightly connected inside the rectangular sleeve ring 14 to ensure the stability of the installation and is not prone to rotation under shaking). At this time, the bottom of the filter bag body 11 has a certain degree of extensibility, providing additional support and buffering during the filtering operation, reducing the impact and vibration received by the filter bag body 11 during the working process, and reducing the risk of damage and deformation of the filter bag body 11, thereby extending its service life. When the filter bag body 11 needs to be replaced and maintained after long-term use, rotate the second ring 13 clockwise to remove the second ring 13, and tear off the first ring 12 from the outer surface of the filter bag body 11, so as to be reused and reduce the cost required for maintenance.

[0033] A support mechanism is sleeved inside the filter bag body 11. The support mechanism includes a tent ring 19, which is sleeved inside the filter bag body 11. The upper end of the tent ring 19 is fixedly connected to a top cover 21, and the top cover 21 is sleeved on the outer surface of the filter bag body 11. Two clamping blocks 22 are slidably connected inside the tent ring 19, and both of the two clamping blocks 22 are in contact with the outer surface of the filter bag body 11. A pull ring 23 is slidably connected inside the top cover 21. Inclined blocks 24 are fixedly connected to both the pull ring 23 and the upper ends of the two clamping blocks 22. The two groups of pull rings 23 are in contact with each other. Return springs 25 are fixedly connected to the outer surfaces of both the pull ring 23 and the two clamping blocks 22, and all three return springs 25 are fixedly connected inside the top cover 21. When placing and installing the filter bag body 11, hold and pull the pull ring 23 towards the end close to the clamping block 22. At this time, the return spring 25 connected to one end of the pull ring 23 is stretched. One inclined block 24 at the upper end of the pull ring 23 is in contact with the other inclined block 24 at the upper end of the clamping block 22. During the sliding process of the pull ring 23, one group of inclined blocks 24 squeezes the other group of inclined blocks 24 to slide towards the side away from the tent ring 19. The two clamping blocks 22 slide and open, and compress the return springs 25 connected to both sides. At this time, the tent ring 19 is inserted into the filter bag body 11 (the upper end of the filter bag body 11 is made of plastic material reinforced with iron wire and has a certain three-dimensional shape). The upper end of the filter bag body 11 is sleeved inside the top cover 21. Release the pull ring 23, and under the action of the three return springs 25, the pull ring 23 and the two clamping blocks 22 are pulled back to their original positions. The two clamping blocks 22 slide and clamp the outer surface of the filter bag body 11. By sleeving the tent ring 19 inside the filter bag body 11, the filter bag body 11 is kept in a specific shape and structure, preventing the filter bag body 11 from collapsing or deforming during the filtering process, and ensuring the stability of the filtering area. The clamping of the two clamping blocks 22 on both sides ensures the stability of the connection between the filter bag body 11 and the tent ring 19. Moreover, when performing the operation of removing the filter bag body 11 for replacement and maintenance, pulling the top cover 21 can drive the filter bag body 11 to be pulled out. Pull the pull ring 23 towards the end close to the clamping block 22, and the filter bag body 11 loses the clamping force and quickly separates and falls off, which is beneficial to improving the stability of the filter bag body 11 during placement and the convenience of replacement.

[0034] One side of the dust collector body 18 is fixedly connected to a jet blowing pipe 26. An air inlet pipe 27 is fixedly connected to the side of the dust collector body 18 close to the jet blowing pipe 26. An exhaust pipe 28 is fixedly connected to the side of the dust collector body 18 away from the jet blowing pipe 26. During the production process, the dust-containing gas is injected into the dust collector body 18 through the air inlet pipe 27. The air containing dust is filtered by the filter bag body 11. The large-particle dust filtered out is collected inside the dust collector body 18 and is exported outward through vibration. The filtered air is discharged outward through the exhaust pipe 28, completing the dust removal of the air. During the working process, the filter bag body 11 can be blown by the jet blowing pipe 26 arranged on one side of the dust collector body 18 to blow off the dust attached to the outer side of the filter bag body 11, thereby completing the cleaning of the filter bag body 11.

[0035] In view of the problems existing in the prior art, the utility model provides a pulse jet bag filter. Before the filter bag body 11 is used, the first ring 12 is fixed outside the filter bag body 11 by bonding. The bottom of the filter bag body 11 is sleeved in the second ring 13, and the rectangular collar 14 connected to the outside of the second ring 13 is aligned with the inclined surface of the collar 15 to be sleeved. At this time, hold the second ring 13 and rotate it counterclockwise. The rectangular collar 14 slides and sleeves on the outer surface of the collar 15. At this time, the bottom of the filter bag body 11 has a certain ductility, providing additional support and buffering during the filtering work, reducing the impact and vibration on the filter bag body 11 during the work process, and reducing the risk of damage and deformation of the filter bag body 11, thereby prolonging its service life.

[0036] Working principle:

[0037] First step, during the production work, the dust-containing gas is injected into the dust collector body 18 through the air inlet pipe 27. The air containing dust is filtered by the filter bag body 11. The large-particle dust filtered out is collected in the dust collector body 18 and is discharged outward by vibration. The filtered air is discharged outward through the exhaust pipe 28, completing the dust removal of the air. During the work process, the filter bag body 11 can be blown by the jet pipe 26 arranged on one side of the dust collector body 18 to blow off the dust attached to the outer side of the filter bag body 11, thereby completing the cleaning of the filter bag body 11.

[0038] Second step, when placing and installing the filter bag body 11, hold and pull the pull ring 23 towards one end close to the clamping block 22. At this time, the return spring 25 connected to one end of the pull ring 23 is stretched. One inclined plane block 24 on the upper end of the pull ring 23 fits with another inclined plane block 24 on the upper end of the clamping block 22. During the sliding process of the pull ring 23, a set of inclined plane blocks 24 squeezes another set of inclined plane blocks 24 to slide towards the side away from the tent ring 19. The two clamping blocks 22 slide and open, squeezing the return springs 25 connected to both sides to compress. At this time, the tent ring 19 is inserted into the filter bag body 11 (the upper end of the filter bag body 11 is made of plastic material reinforced with iron wire and has a certain three-dimensional shape). The upper end of the filter bag body 11 is sleeved in the top cover 21. Release the pull ring 23. Under the action of the three return springs 25, the pull ring 23 and the two clamping blocks 22 are pulled back to their original positions. The two clamping blocks 22 slide and clamp the outer surface of the filter bag body 11. By sleeving the tent ring 19 in the filter bag body 11, the filter bag body 11 maintains a specific shape and structure, preventing the filter bag body 11 from collapsing or deforming during the filtering process, ensuring the stability of the filtering area, and ensuring the stability of the connection between the filter bag body 11 and the tent ring 19 through the clamping of the two clamping blocks 22 on both sides. Moreover, when performing the operation of removing the filter bag body 11 for replacement and maintenance, pulling the top cover 21 can drive the filter bag body 11 to be pulled out. Pull the pull ring 23 towards one end close to the clamping block 22, and the filter bag body 11 loses the clamping force and quickly separates and falls off, which is beneficial to improving the stability of the filter bag body 11 during placement and the convenience of replacement. Before the filter bag body 11 is used, the first ring 12 is fixed outside the filter bag body 11 by bonding. The bottom of the filter bag body 11 is sleeved in the second ring 13, and the rectangular sleeve ring 14 connected to the outside of the second ring 13 is aligned with the inclined surface of the sleeve ring 15 to be sleeved. At this time, hold the second ring 13 and rotate it counterclockwise. The rectangular sleeve ring 14 slides and sleeves on the outer surface of the sleeve ring 15 (the sleeve ring 15 is tightly connected inside the rectangular sleeve ring 14 to ensure the stability of the installation and is not prone to rotation under shaking). At this time, the bottom of the filter bag body 11 has a certain ductility, providing additional support and buffering during the filtering work, reducing the impact and vibration on the filter bag body 11 during the work process, and reducing the risk of damage and deformation of the filter bag body 11, thereby extending its service life. When the filter bag body 11 needs to be replaced and maintained after long-term use, rotate the second ring 13 clockwise to remove the second ring 13, and tear the first ring 12 off the outer surface of the filter bag body 11 for repeated use, reducing the cost required for maintenance.

[0039] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
