Description

Technical Field

[0001] The invention relates to the field of dust removal equipment, and in particular to a dust removal filter bag assembly for efficient dust removal. Background Art

[0002] The bottom of the dust collector after the filter bag is installed is not fixed, so the filter bag and the dust collector box wall and the reinforcing ribs lean against each other, and the filter bag shakes greatly, especially during the dust collector cleaning process. For this reason, Chinese Patent Publication No. CN104383761B provides a bottom fixing assembly for the filter bag of the dust collector, which is fixed up and down and always in a vertical state by matching the bending plate and the connecting part, effectively preventing the filter bag from shaking, reducing the friction between it and the outer wall of the dust collector, and greatly improving the service life of the filter bag;

[0003] However, when the above technical solution is actually used, after the dust-laden air enters the dust filter bag, due to the long strip shape of the filter bag, the gas flows to the bottom of the dust filter bag until it contacts the bottom area of ​​the dust filter bag and is squeezed by the filter bag, thereby filtering the gas. This undoubtedly causes the area near the bottom of the filter bag to bear a larger load, while the area near the top of the filter bag cannot be fully used, and the dust removal efficiency is still poor.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) The present invention uses an extrusion plate and a connecting layer to first connect the air inlet pipe to the equipment pipeline, and then the gas enters the bag body from the air inlet pipe. Under the action of the high-speed airflow, the extrusion plate is driven to move toward the air inlet pipe, and the connecting layer is pushed by the extrusion plate. Under the action of extrusion, the bag body is further closed, which effectively improves the stability of the bag body during operation;

[0017] (2) The present invention also uses a fixed block, a movable block and a connecting plate in coordination.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1 - Figure 5 As shown, this embodiment is a dust filter bag assembly for efficient dust cleaning, comprising a bag body 1, a connecting layer 101 is fixedly installed on the top of the bag body 1, the bag body 1 is fixedly connected to an air intake pipe 102 through the connecting layer 101, the connecting layer 101 is inclined at the top of the bag body 1, and the inclination direction is inclined from the bag body 1 to the air intake pipe 102, one side of the connecting layer 101 is fixedly connected to the top of the bag body 1, and the side of the connecting layer 101 away from the bag body 1 is fixedly connected to the bottom of the air intake pipe 102, and a dust cleaning assembly 2 is fixedly installed inside the bag body 1;

[0029] The dust cleaning component 2 includes a fixing frame 201, an extrusion plate 202 and a fixing block 203. The fixing frame 201 is fixedly installed in the bag body 1, the extrusion plate 202 is movably installed on the fixing frame 201, the extrusion plate 202 is located at the connecting layer 101, and the fixing block 203 is fixedly installed in the fixing frame 201. There are three extrusion plates 202, and the extrusion plates 202 are evenly spaced on the fixing frame 201. The connecting layer 101 is located at the center of the extrusion plate 202. When the bag body 1 is fixedly installed, the equipment outlet pipe is inserted into the inlet pipe 102, and the inlet pipe 102 is limited and fixed by fasteners.

[0030] An inclined rod 206 is fixedly installed on the fixing frame 201, and a rotating rod 207 is movably installed on one end of the inclined rod 206 away from the fixing frame 201. The top of the rotating rod 207 is movably connected with the extrusion plate 202, and a push plate 208 is fixedly installed on the bottom of the rotating rod 207. After the gas enters the bag body 1, it collides with the push plate 208. At this time, the push plate 208 moves downward, thereby driving the rotating rod 207 to rotate with the inclined rod 206 as the fulcrum, thereby pushing the extrusion plate 202 toward the direction of the air inlet pipe 102.

[0031] Specifically, when the gas enters the bag body 1 from the air inlet pipe 102, the high-speed airflow drives the extrusion plate 202 to move toward the air inlet pipe 102, and the extrusion plate 202 pushes the connecting layer 101. Under the action of extrusion, the bag body 1 is further closed, effectively improving the stability of the bag body 1 during operation.

[0032] Example 2: Please refer to Figure 6 - Figure 7 As shown, the present invention also includes a cleaning component 2 which also includes a movable block 204 and a connecting plate 205. The connecting plate 205 is fixedly mounted on the inner wall of the bag body 1. The movable block 204 is movably mounted in the fixed block 203. The movable block 204 is fixedly connected to the connecting plate 205. A spring is fixedly mounted on the fixed frame 201, and the end of the spring away from the fixed frame 201 is fixedly connected to the push plate 208.

[0033] An airbag 1 209 is fixedly mounted on the fixed frame 201, and two ends of the airbag 1 209 are fixedly connected to the push plate 208 and the fixed frame 201 respectively. When the push plate 208 moves toward the fixed frame 201, the spring is gradually compressed, the airbag 1 209 is gradually compressed, and the gas in the airbag 1 209 enters the airbag 2 211. Similarly, when the push plate 208 moves away from the fixed frame 201, the airbag 1 209 is gradually expanded, and the gas in the airbag 2 211 enters the airbag 1 209.

[0034] The cross section of the fixed block 203 is circular, and a plurality of movable grooves 210 are provided on the side of the fixed block 203. The movable block 204 is movably installed in the movable groove 210. An airbag 2 211 is fixedly installed in the fixed block 203. The movable block 204 is fixedly connected to the airbag 2 211. The airbag 2 211 is fixedly connected to the airbag 1 209 through a pipeline. When the gas enters the airbag 2 211 from the airbag 1 209, the airbag 2 211 gradually expands, thereby pushing the movable block 204 to move in the movable groove 210.

[0035] A cross bar 212 is fixedly installed on the fixed frame 201, and one end of the cross bar 212 is fixedly connected to the fixed block 203. There are multiple cross bars 212, and the cross bars 212 are evenly spaced on the outer circumference of the fixed block 203. A support rod 213 is fixedly installed on the connecting plate 205, and one end of the support rod 213 away from the connecting plate 205 is fixedly connected to the edge of the movable block 204. There are multiple connecting plates 205, and the connecting plates 205 are evenly spaced on the inner wall of the bag body 1. When the movable block 204 moves outward from the fixed block 203, the support rod 213 is used to push the connecting plate 205 to move, thereby propping up the inner wall of the bag body 1 to keep a certain tension, thereby improving the stability of the bag body 1.

[0036] Specifically, when the extrusion plate 202 moves, it drives the movable block 204 to extend from the fixed block 203. The fixed block 203 and the movable block 204 form a guiding structure with a small top and a large bottom. When the gas comes into contact with the fixed block 203, it diffuses to the surroundings under the action of the movable block 204. At this time, part of the gas collides with the inner wall of the bag body 1, and the remaining gas continues to move toward the bag body 1, so that the entire bag body 1 participates in the gas dust removal, effectively improving the dust removal efficiency. At the same time, when the movable block 204 extends from the fixed block 203, the movable block 204 is used to push the connecting plate 205 to move, so as to support the inner wall of the bag body 1 and further improve the stability of the bag body 1 during operation.

[0037] When cleaning the inside of the bag body 1, the exhaust pipe is fixedly connected to the air inlet pipe 102 at the top of the bag body 1, and the exhaust equipment is started. At this time, ambient air enters the bag body 1 to recoil the dust attached to the internal through holes of the bag body 1, and the gas flows from the four sides of the bag body 1 to the air inlet pipe 102. When it moves to the air inlet pipe 102, under the action of the airflow, the push plate 208 gradually moves away from the fixed frame 201. At this time, the airbag 1 209 gradually expands, the airbag 2 211 gradually contracts, and the movable block 204 moves to the fixed block 203 to avoid affecting the recoil of the bag body 1.

[0038] While the movable block 204 moves, the connecting plate 205 is pulled away from the filter bag through the support rod 213, thereby driving the filter bag to shrink inward, and the push plate 208 continues to move until the spring force is greater than the gas pressure. The push plate 208 moves toward the fixed frame 201 under the action of the spring. At this time, the airbag 1 209 is squeezed, and the airbag 211 expands to drive the movable block 204 to move, thereby pushing the connecting plate 205 to move toward the inner wall of the filter bag. The above steps are repeated, and the push plate 208 and the movable block 204 are used to cooperate with each other to drive the bag body 1 to vibrate continuously, so that the dust particles blocking the through hole fall off, thereby effectively improving the cleaning efficiency of the bag body 1.

[0039] Combining the first and second embodiments, it can be known that under the action of the high-speed airflow, the extrusion plate 202 is driven to move toward the air inlet pipe 102, and the extrusion plate 202 is used to push the connecting layer 101. Under the action of extrusion, the bag body 1 is further closed, which effectively improves the stability of the bag body 1 during operation. In addition, through the coordinated use of the fixed block 203, the movable block 204 and the connecting plate 205, the fixed block 203 and the movable block 204 form a guide structure with a small upper part and a large lower part.

[0040] When the gas comes into contact with the fixed block 203, it diffuses to the surroundings under the action of the movable block 204. At this time, part of the gas collides with the inner wall of the bag body 1, and the remaining gas continues to move toward the bag body 1, so that the entire bag body 1 participates in the gas dust removal, effectively improving the dust removal efficiency, and the movable block 204 is used to push the connecting plate 205 to move, so as to support the inner wall of the bag body 1, further improving the stability of the bag body 1 during operation.

[0041] The working process and principle of the present invention are as follows:

[0042] First, under the action of high-speed airflow, the extrusion plate 202 is driven to move toward the air inlet pipe 102, and the extrusion plate 202 is used to push the connecting layer 101. Under the action of extrusion, the bag body 1 is further closed, which effectively improves the stability of the bag body 1 during operation;

[0043] Furthermore, by using the fixed block 203, the movable block 204 and the connecting plate 205 in coordination, the fixed block 203 and the movable block 204 form a guide structure with a small top and a large bottom. When the gas comes into contact with the fixed block 203, it diffuses to the surroundings under the action of the movable block 204. At this time, part of the gas collides with the inner wall of the bag body 1, and the remaining gas continues to move toward the bag body 1, so that the entire bag body 1 participates in the gas dust removal, effectively improving the dust removal efficiency.

[0044] Furthermore, the movable block 204 is used to push the connecting plate 205 to move, thereby supporting the inner wall of the bag body 1, and further improving the stability of the bag body 1 during operation;

[0045] In summary, the present invention can effectively improve the dust removal efficiency of the bag body 1 while ensuring the stability of the bag body 1.
