Description

Technical Field

[0001] This utility model relates to a filter bag frame for a baghouse dust collector, specifically a filter bag frame for a baghouse dust collector, belonging to the technical field of baghouse dust collector components. Background Technology

[0002] The filter bag cage of a baghouse dust collector is one of the core components of the dust collector. It provides rigid support for the filter bag and prevents the filter bag from collapsing or deforming due to airflow under negative (or positive) pressure. When the dust collector is running, the dust-laden airflow passes through the outside or inside of the filter bag, and the cage needs to withstand the airflow pressure to maintain the normal unfolding state of the filter bag.

[0003] However, the filter bag is only connected to the tube sheet through the elastic ring at the bag opening, which results in poor connection strength. At the same time, the traditional filter bag skeleton can only support the inside of the filter bag and does not provide additional reinforcement to the bag opening area. Therefore, the impact of the pulse airflow during dust removal can easily cause the bag opening to loosen and the filter bag to fall off, resulting in poor stability in use. Utility Model Content

[0004] The purpose of this invention is to provide a filter bag frame for a baghouse dust collector to solve the above-mentioned problems. While fixing the inside of the filter bag, it can also reinforce the bag opening to prevent the filter bag from falling off under the action of pulse force, thereby improving the stability of use.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a filter bag frame for a baghouse dust collector, including a top support, a fixing structure on the top support, the fixing structure including a rotating rod and a shaft, the shaft being rotatably connected to the top support, and two sliding sleeves being slidably connected to the top support. The two sliding sleeves are respectively threadedly connected to both ends of the shaft, and a stop block is fixedly connected to the end of the sliding sleeve, the stop block being slidably connected to the top support.

[0006] Preferably, two rotating rods are fixedly connected to the middle of the shaft, and the two rotating rods are symmetrically distributed about the middle of the shaft.

[0007] Preferably, the threads at both ends of the shaft are in opposite directions, and the two abutments are symmetrically arranged about the middle of the top support.

[0008] Preferably, the sliding sleeve has two cut surfaces, which are symmetrically distributed about the middle of the sliding sleeve.

[0009] Preferably, one side of the abutment has an arc-shaped structure, and the cross-section between the abutment and the sliding sleeve has a T-shaped structure.

[0010] Preferably, a plurality of support rods are provided through the top support, and a fixing nut is threaded onto the support rod, with the fixing nut abutting against the top support.

[0011] Preferably, the plurality of support rods are arranged in a circular array about the center of the top support, and the bottom ends of the plurality of support rods are fixedly connected to the same bottom support.

[0012] Preferably, the support rod is covered with multiple anti-corrosion sleeves, and two reinforcing frames are provided through the multiple support rods, with the top side of the reinforcing frame abutting against the multiple adjacent anti-corrosion sleeves.

[0013] Preferably, the support rod is made of metal, and the reinforcing frame and anti-corrosion sleeve are both made of corrosion-resistant plastic.

[0014] The beneficial effects of this utility model are as follows: During use, after the elastic ring of the filter bag and the tube sheet are engaged, the top support can be placed on the top of the filter bag. One side of the top support will abut against the top side of the tube sheet. After the top support is placed, the shaft can be rotated. The rotation of the shaft will drive the two sliding sleeves to move in opposite directions. The movement of the sliding sleeves will drive the abutment blocks to move, so that the two abutment blocks move towards the filter bag at the same time. When the two abutment blocks are pressed against the filter bag at the same time, the shaft can be stopped. At this time, the inner side of the filter bag opening and the outer side of the abutment block are pressed against each other, and the outer side of the filter bag opening and the tube sheet are pressed against each other, thereby reinforcing the filter bag opening and preventing the filter bag from falling off under the action of pulse force, thus improving the stability of use. Moreover, when the two abutment blocks abut against the filter bag at the same time, the top support can also be positioned and fixed, thereby preventing the top support from moving after installation and improving the stability of the top support after installation.

[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 Figures 1-5 As shown, a filter bag frame for a baghouse dust collector includes a top support 1. The top support 1 is provided with a fixing structure 2. The fixing structure 2 includes a rotating rod 201 and a shaft 202. The shaft 202 is rotatably connected to the top support 1. Two sliding sleeves 203 are slidably connected to the top support 1. The two sliding sleeves 203 are threadedly connected to both ends of the shaft 202. A stop block 204 is fixedly connected to the end of the sliding sleeve 203. The stop block 204 is slidably connected to the top support 1.

[0023] As a technical optimization of this utility model, two rotating rods 201 are fixedly connected to the middle of the shaft 202, so the shaft 202 can be easily rotated by holding the rotating rods 201. The two rotating rods 201 are symmetrically distributed about the middle of the shaft 202.

[0024] As a technical optimization of this utility model, the threads at both ends of the shaft 202 are opposite, so that when the shaft 202 rotates in one direction, the two abutments 204 can move in opposite directions, and the two abutments 204 are symmetrically arranged about the middle of the top support 1.

[0025] As a technical optimization of this utility model, the sliding sleeve 203 is provided with two cut surfaces 205, so that the sliding sleeve 203 can only slide in the axial direction of the shaft 202, and cannot rotate with the shaft 202. The two cut surfaces 205 are symmetrically distributed about the middle of the sliding sleeve 203.

[0026] As a technical optimization of this utility model, one side of the abutment 204 has an arc-shaped structure, and the cross section between the abutment 204 and the sliding sleeve 203 has a T-shaped structure. Therefore, the contact area between the abutment 204 and the filter bag can be increased, thereby improving the reinforcement effect.

[0027] As a technical optimization of this utility model, a plurality of support rods 3 are provided through the top support 1. The support rods 3 are made of metal. The multiple support rods 3 can support the inside of the filter bag. A fixing nut 4 is threaded on the support rod 3. The fixing nut 4 abuts against the top support 1. Therefore, the fixing nut 4 can be unscrewed from the support rod 3 to disassemble each component, avoiding the need to replace the whole component when a certain component is damaged, thereby effectively saving the cost of use.

[0028] As a technical optimization of this utility model, the multiple support rods 3 are arranged in a circular array about the center of the top support 1, and the bottom ends of the multiple support rods 3 are fixedly connected to the same bottom support 7, so the bottom ends of the multiple support rods 3 can be reinforced by the bottom support 7.

[0029] As a technical optimization of this utility model, the support rod 3 is covered with multiple anti-corrosion sleeves 5. The anti-corrosion sleeves 5 can prevent the metal support rod 3 from directly contacting the filter bag and being corroded and damaged, thereby improving the safety of use. Two reinforcing frames 6 are provided through the multiple support rods 3. Both the reinforcing frames 6 and the anti-corrosion sleeves 5 are made of corrosion-resistant plastic. The two reinforcing frames 6 can reinforce the multiple support rods 3. The top side of the reinforcing frame 6 and the adjacent multiple anti-corrosion sleeves 5 are in contact.

[0030] In use, after the elastic ring of the filter bag and the tube sheet are engaged, the top support 1 can be placed on top of the filter bag. Once the top support 1 is in place, multiple support rods 3 will be located inside the filter bag, thus supporting the filter bag and preventing deformation under pressure. One side of the top support 1 will abut against the top side of the tube sheet. After the top support 1 is in place, the shaft 202 can be rotated by holding the rotating rod 201. The rotation of the shaft 202 will drive two threaded rods... The sliding sleeve 203 moves in opposite directions, which drives the abutment blocks 204 to move, causing both abutment blocks 204 to move towards the filter bag simultaneously. Once both abutment blocks 204 are pressed against the filter bag, the rotating shaft 202 stops rotating. At this point, the inner side of the filter bag opening is pressed against the outer side of the abutment blocks 204, and the outer side of the filter bag opening is pressed against the tube sheet, thus reinforcing the filter bag opening and preventing it from falling off under pulse force, improving stability during use. The abutment block 204, when in contact with the filter bag, also positions and fixes the top support 1, thus preventing it from moving after installation and improving its stability. Although the metal support rod 3 has high support strength, it has poor corrosion resistance and is easily corroded by long-term contact with the filter bag. Therefore, by covering the support rod 3 with a plastic anti-corrosion sleeve 5, direct contact between the support rod 3 and the filter bag can be avoided, thus ensuring safety. When the anti-corrosion sleeve 5 needs to be cleaned and replaced, the fixing nut 4 can be unscrewed from the top of the support rod 3. After all the fixing nuts 4 on the support rod 3 have been unscrewed, the top support 1 can be removed from the multiple support rods 3, and then the anti-corrosion sleeve 5 can be removed from the support rod 3 for cleaning and replacement. The reinforcing frame 6 can also be removed for cleaning and replacement. Thus, when a part of the frame is damaged, only the individual part needs to be replaced, instead of replacing the entire frame, effectively saving on usage costs.
