Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a structure for preventing bag detachment in a pulse bag dust collector. Background Technology

[0002] A pulse jet baghouse dust collector is a highly efficient dust removal device. Its working principle is as follows: dust-laden gas enters the dust collector through the inlet and first encounters the inclined plate and baffle between the inlet and outlet. The airflow then turns and flows into the dust hopper. In the dust hopper, due to the reduced airflow velocity, coarse dust particles fall directly to the bottom of the hopper due to gravity, while the airflow containing finer dust is filtered through the filter bags. As the filtration process continues, dust gradually accumulates on the outer surface of the filter bags, increasing the bag's resistance and affecting dust removal efficiency. At this point, the pulse jet cleaning system of the pulse jet baghouse dust collector comes into play.

[0003] For example, a Chinese patent (publication number: CN219441062U) discloses a fixing structure for a small pulse bag filter, relating to the field of bag filter technology. It includes a mounting plate and a quick-fix assembly. The mounting plate has a mounting groove on its outer side. The quick-fix assembly, used for the rapid installation of filter bags in the small pulse bag filter, is located on the upper surface of the mounting plate. The quick-fix assembly includes a through hole, a sealing inner ring, a filter bag, a tension strap, and a hook. The sealing inner ring is installed at the upper end of the through hole, and the filter bag is located inside the sealing inner ring. The tension strap is connected to the end of the filter bag, and a hook is located at the end of the tension strap. A pull hook is located on the outer side of the hook. This fixing structure for a small pulse bag filter allows the mounting plate to be quickly fixed inside the small pulse bag filter by bolts passing through the mounting hole. The quick-fix assembly quickly stretches and limits the filter bag, ensuring the filter bag opening is fully open to prevent leakage. The protective assembly reduces wear when fixing the filter bag.

[0004] However, the structure is not effective at preventing detachment. Since the structure is fixed by tension straps and hooks, and dust removal requires blowing air on both sides of the filter bag to achieve dust collection and removal, the filter bag needs to be shaken rapidly. The connection method of this structure makes it easy to fall off when the filter bag is shaken. Therefore, a fixing structure for a small pulse bag dust collector is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-bag detachment structure for a pulse bag dust collector, which has advantages such as good anti-bag detachment effect and solves the problem of bag detachment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a structure for preventing bag detachment in a pulse bag dust collector, comprising a stabilizing ring, a bracket fixed to the bottom of the stabilizing ring, the inner side of the bracket being coaxial and flush with the stabilizing ring, a snap-fit ​​component for improving the connection stability of the bag being provided at the bottom of the stabilizing ring, a dust bag being fixed to the bottom of the snap-fit ​​component and located outside the bracket, and a stabilizing component for improving the connection stability between the dust bag and the bracket being provided on the outer surface of the dust bag;

[0007] The bottom of the stabilizing ring is provided with an annular groove. The snap-fit ​​assembly includes a stabilizing seat that is threadedly connected to the inner wall of the annular groove. Both sides of the stabilizing seat are provided with limiting parts that penetrate the stabilizing seat and extend into the stabilizing ring. The bottom of the stabilizing ring and the outer side of the annular groove are provided with two T-shaped grooves. Each T-shaped groove is provided with a positioning part that extends out of the T-shaped groove and abuts against the rear side of the limiting part.

[0008] Furthermore, the top of the stabilizing base and both the left and right sides of the stabilizing base are provided with movable slots, and both the left and right sides of the stabilizing base are provided with telescopic holes that communicate with the movable slots.

[0009] Furthermore, each of the limiting parts includes a locking block that is movably connected to the moving groove, passes through the top of the stabilizing base, and extends into the stabilizing ring. Multiple compression springs are fixed on opposite sides of the two locking blocks. The sides of the multiple compression springs away from the locking blocks are fixed to the sidewall of the moving groove. The locking blocks extend outside the stabilizing base through telescopic holes.

[0010] Furthermore, each of the positioning parts includes a T-shaped block that is movably connected to the T-slot, the T-shaped block extending outside the T-slot, and a positioning block located behind the snap-fit ​​block and abutting against the snap-fit ​​block fixed at the bottom of the T-shaped block.

[0011] Furthermore, a pressure plate is fixed on the opposite side of each of the snap-fit ​​blocks, and each snap-fit ​​block abuts against the positioning block through the pressure plate.

[0012] Furthermore, movable magnets are embedded on the opposite sides of the two T-blocks, and stabilizing magnets are embedded on the sidewalls of the two T-slots that are close to each other.

[0013] Furthermore, the stabilizing ring has two clearance grooves that are connected to the annular groove and are located directly above the two moving grooves respectively. Each clearance groove has a limiting block that extends into the snap-fit ​​block fixed on its side wall.

[0014] Furthermore, each of the stabilizing components includes a threaded rod that passes through the dust bag and the bracket in sequence. A thrust plate is fixed to the side of the threaded rod away from the bracket. A gasket is movably connected to the outer surface of the threaded rod and located outside the dust bag, with two sides respectively abutting against the dust bag and the thrust plate. A support block is movably connected to the outer surface of the threaded rod and located between the dust bag and the bracket. A nut is threadedly connected to the outer surface of the threaded rod and located inside the bracket.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The anti-bag detachment structure of this pulse bag dust collector ensures a stable connection between the snap-fit ​​component and the stabilizing ring. When disassembly or replacement is required, simply move the two positioning blocks, press the two snap-fit ​​blocks, and then rotate the stabilizing seat. This structure is very convenient to assemble and disassemble, has a reliable connection, and can achieve a good anti-detachment effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1This embodiment of a pulse bag dust collector includes a bag-proof structure to prevent the dust bag from falling off. A support 2 is fixed to the bottom of the stabilizing ring 1. The support 2 provides stable support for the dust bag 3 and reduces the deformation of the dust bag 3 when filtering dust. The inner side of the support 2 is coaxial with and flush with the stabilizing ring 1. This design can improve the airflow speed and improve the overall efficiency. The bottom of the stabilizing ring 1 is provided with a snap-fit ​​component 5 to improve the connection stability of the dust bag. The bottom of the snap-fit ​​component 5 and the outer side of the support 2 are fixed with the dust bag 3. The outer surface of the dust bag 3 is provided with a stabilizing component 4 to improve the connection stability between the dust bag 3 and the support 2. The stabilizing component 4 can effectively ensure the connection stability between the dust bag 3 and the support 2 and improve the overall stability of the dust bag 3.

[0023] In addition, each stabilizing component 4 includes a threaded rod 401 that passes through the dust bag 3 and the bracket 2 in sequence. A thrust plate is fixed to the side of the threaded rod 401 away from the bracket 2. The outer surface of the threaded rod 401, located on the outside of the dust bag 3, is movably connected to a gasket 402 on both sides, which abut against the dust bag 3 and the thrust plate respectively. The gasket 402 can protect the dust bag 3 and prevent the thrust plate from directly contacting the dust bag 3, thereby improving the service life of the dust bag 3. The outer surface of the threaded rod 401, located between the dust bag 3 and the bracket 2, is movably connected to a support block 403. The support block 403 can provide a gap between the dust bag 3 and the bracket 2 to ensure that dust is shaken off smoothly. The outer surface of the threaded rod 401, located on the inside of the bracket 2, is threadedly connected to a nut 404. The nut 404 can cooperate with the threaded rod 401 to ensure connection stability.

[0024] In this embodiment, the bracket 2 and the stabilizing component 4 can effectively improve the stability of the dust bag 3, while providing sufficient support for the dust bag 3 to ensure that the dust bag 3 can filter dust smoothly.

[0025] Please refer to it again. Figure 1 and Figures 2 to 3 To ensure connection stability, the bottom of the stabilizing ring 1 in this embodiment is provided with an annular groove. The snap-fit ​​assembly 5 includes a stabilizing seat 501 that is threadedly connected to the inner wall of the annular groove. The threaded connection has high stability and is easy to disassemble. Both sides of the stabilizing seat 501 are provided with limiting parts that penetrate the stabilizing seat 501 and extend into the stabilizing ring 1. The limiting parts can limit the threaded connection and ensure connection stability. Two T-shaped grooves are provided at the bottom of the stabilizing ring 1 and on the outside of the annular groove. Each T-shaped groove is provided with a positioning part that extends out of the T-shaped groove and abuts against the rear side of the limiting part. The positioning part can position the limiting part and ensure smooth limiting.

[0026] It should be further explained that the top of the stabilizing base 501 and both the left and right sides of the stabilizing base 501 are provided with moving slots. Both the left and right sides of the stabilizing base 501 are provided with telescopic holes that communicate with the moving slots, allowing the locking blocks 502 to extend smoothly. Each limiting part includes a locking block 502 that is movably connected to the moving slot, passes through the top of the stabilizing base 501, and extends into the stabilizing ring 1. Multiple compression springs 503 are fixed on the opposite side of the two locking blocks 502. The compression springs 503 can provide continuous and stable power to the locking blocks 502, thereby ensuring the stability of the connection between the limiting block 6 and the locking blocks 502. The side of the multiple compression springs 503 away from the locking blocks 502 is fixed to the side wall of the moving slot. The locking blocks 502 extend to the outside of the stabilizing base 501 through the telescopic holes.

[0027] It is understood that each positioning part includes a T-shaped block 505 that is movably connected to the T-slot. The T-shaped block 505 extends outside the T-slot and can move within the T-slot. A positioning block 504 is fixed at the bottom of the T-shaped block 505, located behind the snap-fit ​​block 502 and abutting against the snap-fit ​​block 502. A pressure plate is fixed on the opposite side of each snap-fit ​​block 502. Each snap-fit ​​block 502 abuts against the positioning block 504 through the pressure plate. The friction between the positioning block 504 and the snap-fit ​​block 502 can limit the movement of the snap-fit ​​block 502. At the same time, both the positioning block 504 and the snap-fit ​​block 502 can effectively limit the positioning of the stabilizing seat 501.

[0028] Furthermore, movable magnets are embedded on opposite sides of the two T-shaped blocks 505, and stabilizing magnets are embedded on the sidewalls of the two T-shaped slots that are close to each other. The movable magnets and stabilizing magnets have opposite magnetic poles, which can ensure that the two attract each other stably. The stabilizing ring 1 has two clearance slots that are connected to the annular slots and are located directly above the two movable slots. Each clearance slot has a limiting block 6 that extends into the snap-fit ​​block 502 fixed on its sidewall. The clearance slots allow the snap-fit ​​block 502 to move.

[0029] In this embodiment, the snap-fit ​​block 502 and the limiting block 6 on the snap-fit ​​assembly 5 cooperate to prevent the stabilizing seat 501 from rotating, thereby ensuring that the threaded connection between the stabilizing seat 501 and the stabilizing ring 1 is stable and reliable.

[0030] Understandably, the combination of the stabilizing component 4 and the snap-fit ​​component 5 can effectively improve the stability of the dust bag 3 and prevent the dust bag 3 from falling off. At the same time, the bracket 2 can also provide good support for the dust bag 3.

[0031] The working principle of the above embodiments is as follows:

[0032] When the dust collector is in use, the air carrying dust from the outside will pass through the outside of the dust bag 3. Due to the support of the stabilizing component 4 and the bracket 2, the dust bag 3 is not easily deformed, and the dust will be blocked on the outside of the dust bag 3. When the dust bag 3 is being cleaned, the pulse air blows into the dust bag 3 through the stabilizing ring 1. The dust bag 3 will partially expand outward and shake. During the shaking process, the snap-fit ​​block 502 and the limiting block 6 cooperate to ensure the stability of the threaded connection between the stabilizing seat 501 and the stabilizing ring 1. At the same time, the positioning block 504 can block the snap-fit ​​block 502, further improving the stability of the threaded connection and preventing it from falling off. The shaking force will eventually be transmitted to the T-shaped block 505. However, due to the magnetic attraction effect of the T-shaped block 505, it can be repeatedly pushed back to its original position, thereby offsetting the effect of shaking, ensuring connection stability, and successfully preventing the dust bag 3 from falling off.
