[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1-4 This utility model provides a pulse bag dust collector with easy filter bag replacement.

[0022] In a preferred embodiment, the enclosure includes a housing 1. A top plate 2 is bolted to the top of the housing 1. A mounting plate 3 is provided at the bottom of the top plate 2. A plurality of first circular blocks 301 are fixedly connected to the bottom of the mounting plate 3. A mounting sleeve 302 is fixedly connected to the bottom of the first circular blocks 301. A filter bag 4 is provided inside the mounting sleeve 302. A second circular block 402 is fixedly connected to the top of the filter bag 4. The bottom of the second circular block 402 is in contact with the first circular blocks 301. Movable grooves 403 are provided on both sides of the second circular block 402. A connecting post 406 and a locking block 405 are provided inside the movable groove 403. A stud 404 is fixedly connected to the bottom of the locking block 405. A fixing opening 303 is provided at the top of the first circular block 301. The inside of the fixing opening 303 is threadedly connected to the stud 404. A rotating block 407 is fixedly connected to the top of the connecting post 406.

[0023] During dust removal operations, dust-laden gas enters the housing 1. As the airflow passes through the filter bag 4, the dust is trapped by the filter bag 4, and the purified gas is discharged. When the filter bag 4 needs to be replaced due to dust accumulation or damage, first remove the bolts connecting the housing 1 and the top plate 2, remove the top plate 2, and then rotate the rotating block 407 to drive the connecting column 406 and the locking block 405 to rotate, causing the stud 404 at the bottom of the locking block 405 to rotate in the fixing port 303 of the first round block 301 and disengage from the threaded connection. Since the diameter of the locking block 405 is larger than the diameter of the connecting column 406, the filter bag 4 can be pulled upwards directly to easily pull out the second round block 402 along with the filter bag 4 from the mounting sleeve 302. After the new filter bag 4 is replaced, the second round block 402 is attached to the bottom of the first round block 301, and the rotating block 407 drives the stud 404 to be screwed into the fixing port 303, so that the bottom of the locking block 405 presses against the top surface of the movable groove 403 to complete the fixation, and then the top plate 2 is reinstalled.

[0024] By utilizing the diameter difference between the locking block 405 and the connecting post 406, and in conjunction with the threaded connection between the rotating block 407, the stud 404, and the fixing port 303, the filter bag 4 can be quickly disassembled. Simply loosen the stud 404 and pull it upwards to remove it, greatly simplifying the replacement process and solving the problem of inconvenient filter bag replacement during daily maintenance.

[0025] In a preferred embodiment, the front of the box 1 is provided with an observation window 101, the top of one side of the box 1 is fixedly connected with a sewage inlet 102, and the bottom of the box 1 is fixedly connected with a sewage outlet 103.

[0026] Dust-laden gas enters the chamber 1 through the inlet 102. Inside the chamber 1, the gas is filtered by the filter bag 4, and the dust particles are trapped. Personnel can observe the dust accumulation, damage, and gas filtration status of the filter bag 4 inside the chamber 1 in real time through the viewing window 101.

[0027] In a preferred embodiment, a steel ring 401 is fixedly connected to the top of the filter bag 4, and the steel ring 401 fits against the inner wall of the mounting sleeve 302.

[0028] The steel ring 401 can support the top opening of the filter bag 4 and prevent the filter bag 4 from deforming under the action of airflow or sticking to the mounting sleeve 302.

[0029] In a preferred embodiment, the first circular blocks 301 are evenly distributed along the bottom of the mounting plate 3, and the central axis of each first circular block 301 is collinear with the central axis of the corresponding mounting sleeve 302.

[0030] The first circular blocks 301 are evenly distributed along the bottom of the mounting plate 3, and the central axis of each first circular block 301 is collinear with the central axis of the corresponding mounting sleeve 302, so that the filter bags 4 in each mounting sleeve 302 are evenly arranged in the housing 1. After the dust-laden gas enters the housing 1, it can be evenly distributed to each filter bag 4 for filtration, avoiding some filter bags 4 from accumulating dust or breaking quickly due to excessive load.

[0031] In a preferred embodiment, the diameter of the locking block 405 is larger than the diameter of the connecting post 406, and the bottom of the locking block 405 can be tightly pressed against the inner top surface of the movable groove 403.

[0032] This makes fixing and removing the filter bag 4 simple and convenient, further improving the replacement efficiency of the filter bag 4.

[0033] In a preferred embodiment, the filter bag 4 is made of polyester needle-punched felt.

[0034] Filter bags made of polyester needle-punched felt have high filtration efficiency, which can effectively improve the dust removal quality of the equipment and avoid the decline in dust removal effect due to insufficient filtration performance of the filter bags.

[0035] The foregoing description, with reference to preferred embodiments, illustrates an exemplary embodiment of a pulse bag dust collector that facilitates filter bag replacement provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
