Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically to the filter bag assembly of a bag filter. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. It uses the filtration effect of the filter media to filter dust-laden gas and purify the gas.

[0003] Existing baghouse dust collectors mainly consist of a housing with a dust inlet and a clean air outlet. A cleaning system, typically a pulse-jet cleaning system, is located at the top of the housing. A dust hopper with a dust discharge device is located at the bottom of the housing. Inside the housing is a filter chamber containing filter bag assemblies. Each filter bag assembly includes a tube sheet with several mounting holes for installing filter bags, each with a bag cage inserted inside. During operation, dust-laden gas enters the filter chamber through the dust inlet. Coarser particles fall directly into the dust hopper, while finer particles rise with the gas to the surface of the filter bags. After filtration, the dust is trapped on the filter bag surface, and the purified gas is discharged into the atmosphere through the clean air outlet. As filtration continues, the dust accumulated on the surface of the filter bag increases, causing the equipment resistance to rise to a set value. When this occurs, the pulse jet cleaning system injects high-pressure compressed air into the filter bag. The high-speed reverse airflow causes the filter bag to suddenly expand, causing the attached dust to fall off and into the ash hopper. The dust is then discharged through the ash removal device, thus achieving dust removal.

[0004] Currently, in the filter bag assemblies of existing baghouse dust collectors, the filter bag is usually a long strip with a rubber ring at the opening, which is fixed to the tube sheet by snap-fit. In practice, the side of the filter bag closest to the operator needs to be snapped into the mounting hole of the tube sheet first, and then the other half needs to be pulled back to snap the rubber ring at the opening of the filter bag into the mounting hole. However, in order to prevent air leakage, the filter bag must be snapped flat in the mounting hole. Therefore, if it is found to be uneven, it needs to be tapped with a hammer to make it snapped in evenly, which makes the operation more troublesome, time-consuming and labor-intensive. Utility Model Content

[0005] The purpose of this utility model is to provide a filter bag assembly for a baghouse dust collector to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: a filter bag assembly of a bag filter includes a tube sheet, on which a plurality of filter bags are disposed, and a plurality of through holes are formed. An installation ring is provided at each corresponding through hole position on the tube sheet. A connecting sleeve for engaging with the installation ring is provided at the top of each filter bag. A slot is vertically formed on the inner sidewall of the installation ring, and a limiting groove communicating with the slot is circumferentially formed on the inner sidewall of the installation ring. A limiting block is provided on the outer sidewall of the connecting sleeve, and the limiting block is used to sequentially engage with the slot and the limiting groove.

[0007] As a further feature of this invention, an elastic component is provided inside the limiting groove, which is used to push the limiting block against the top wall of the limiting groove.

[0008] As a further feature of this invention, the top wall of the limiting groove is provided with an embedding groove for embedding the limiting block.

[0009] As a further feature of this invention, the elastic component includes an annular plate, and a plurality of elastic blocks are connected to the bottom of the annular plate, the elastic blocks being fixedly connected to the bottom wall of the limiting groove.

[0010] As a further feature of this invention, the connecting sleeve is provided with a plurality of lifting blocks.

[0011] As a further feature of this invention, the perforated plate is made of stainless steel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] When installing the filter bag, this invention allows the connecting sleeve to be inserted into the installation ring first, causing the limiting block to be inserted into the slot and slide until the slot and the limiting slot connect. Then, rotating the connecting sleeve will cause the limiting block to rotate as well, thus locking the limiting block into the limiting slot. The limiting slot then locks the limiting block in place, fixing the connecting sleeve inside the installation ring, thereby achieving filter bag installation with high flatness. When the filter bag needs to be removed, simply rotate the connecting sleeve until the limiting block rotates to the point where the slot and the limiting slot connect. Then, pull the connecting sleeve outward to allow the limiting block to slide out through the slot, thus removing the filter bag. The installation and removal operations are convenient, simple, time-saving, and labor-saving. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5 As shown, the filter bag assembly of the bag filter dust collector includes a tube sheet 1, which is made of stainless steel, possessing high strength and hardness, and is not easily corroded, thus exhibiting good durability. Several filter bags 2 are mounted on the tube sheet 1, and several through holes are formed in the tube sheet 1. A mounting ring 3 is provided at each corresponding through hole position. A connecting sleeve 4 is provided on the top of the filter bag 2 for engaging with the mounting ring 3, and several lifting blocks 11 are provided on the connecting sleeve 4. The lifting blocks 11 provide a force point for rotating the connecting sleeve 4, making operation easier and less strenuous. A slot 5 is vertically formed on the inner wall of the mounting ring 3, and a limiting groove 6 communicating with the slot 5 is circumferentially formed on the inner wall of the mounting ring 3. A limiting block 7 is provided on the outer wall of the connecting sleeve 4. The limiting block 7 is used for... When installing the filter bag 2, the connecting sleeve 4 can be inserted into the mounting ring 3 first, so that the limiting block 7 is inserted into the slot 5 and slides to the point where the slot 5 and the limiting groove 6 are connected. Then, the connecting sleeve 4 is rotated, which will drive the limiting block 7 to rotate, thereby inserting the limiting block 7 into the limiting groove 6. The limiting groove 6 then locks the limiting block 7, thus fixing the connecting sleeve 4 inside the mounting ring 3, thereby realizing the installation of the filter bag 2. The installation is relatively flat. When it is necessary to remove the filter bag 2, simply rotate the connecting sleeve 4 so that the limiting block 7 rotates to the point where the slot 5 and the limiting groove 6 are connected. Then, the connecting sleeve 4 can be pulled outward, allowing the limiting block 7 to slide out through the slot 5, thus removing the filter bag 2. The disassembly and assembly operations are convenient and simple, saving time and effort.

[0022] Please see Figure 2-5 As shown, an elastic component is provided inside the limiting groove 6. The elastic component is used to push the limiting block 7 against the top wall of the limiting groove 6. Through the elastic support of the elastic component, the limiting block 7 can be pressed tightly against the top wall of the limiting groove 6 to prevent shaking, thereby improving the installation firmness of the filter bag 2 on the tube sheet 1. Furthermore, a groove 8 for embedding the limiting block 7 is provided on the top wall of the limiting groove 6. By pushing with the elastic component, the limiting block 7 located inside the limiting groove 6 can also be pushed into the embedded groove 8. Thus, the groove 8 limits the positioning of the limiting block 7. The position can further improve the installation firmness of filter bag 2 on tube sheet 1. The elastic component includes an annular plate 9, and several elastic blocks 10 are connected to the bottom of the annular plate 9. The elastic blocks 10 are fixedly connected to the bottom wall of the limiting groove 6. When the limiting block 7 is inserted into the limiting groove 6, it will squeeze the annular plate 9, causing the elastic block 10 to be compressed and deformed, thereby pushing the annular plate 9 upward. The annular plate 9 can push the limiting block 7 to firmly press against the top wall of the annular groove, thereby fixing the connecting sleeve 4 inside the mounting ring 3.
