Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dust removal devices, specifically to an auxiliary dust removal device for a bag filter. Background Technology
[0002] The auxiliary dust removal device for baghouse dust collectors restores the filtration performance of the filter bags by periodically removing dust from them, thereby ensuring the continuous and efficient operation of the dust collector. When dust-laden gas passes through the baghouse dust collector, the dust removal mechanism is usually manually controlled. After the mechanism stops, the operator manually vibrates the mechanism for several tens of seconds to shake off the dust adhering to the outer surface of the filter bags. The dust that falls into the dust collection container is then manually pulled out and removed.
[0003] However, this manual dust removal method is too time-consuming and labor-intensive. During manual vibration dust removal, large dust particles will fall directly into the dust hopper due to gravity and inertia. Some small dust particles may be too fine or sticky, resulting in some small dust particles remaining on the filter bags. Over time, some will remain after each dust removal. When dust gradually accumulates on the surface of the filter bags, forming a dust layer, simply using manual vibration to clean the filter bags will prevent some fine dust particles from falling off easily. If the filter bags are not cleaned or replaced in time, it will create resistance for the dust collector, making it difficult for dust to be separated normally, reducing the dust removal effect of the filter bags, and thus affecting the overall dust removal efficiency. Utility Model Content
[0004] This utility model proposes an auxiliary dust removal device for baghouse dust collectors, which solves the problems in the prior art where dust accumulates on the surface of the bag due to increasingly longer dust removal times, resulting in insignificant dust removal effect and secondary pollution caused by dust accumulation inside the equipment.
[0005] The technical solution of this utility model is as follows:
[0006] An auxiliary dust removal device for a baghouse dust collector includes a dust collector body and a sealing cover. Multiple filter bags are disposed inside the dust collector body, and a base is fixedly connected to the bottom of the dust collector body. The sealing cover is detachably connected to the top of the dust collector body. The device also includes:
[0007] The bracket is fixedly connected to the top of the sealing cover;
[0008] A lifting and sweeping mechanism is disposed on the top of the sealing cover and is used to assist in cleaning the multiple cloth bags;
[0009] A vibration cleaning mechanism is provided on the top of the base and is used to perform vibration cleaning on the multiple cloth bags.
[0010] A side pull-out plate is slidably connected to the outer side wall of the dust collector body near the sealing cover, and is used to pull out so that the lifting and cleaning mechanism can be lowered.
[0011] An air tank, which is fixedly connected to the side extraction plate, is used to store and release compressed air.
[0012] Preferably, the lifting and cleaning mechanism includes:
[0013] An electric cylinder is mounted on the top of the bracket, and a through hole is provided on the top of the sealing cover;
[0014] A lifting rod is fixedly connected to the output end of the electric cylinder;
[0015] A connecting plate, which is fixedly connected to the other end of the lifting rod;
[0016] A plurality of silicone brushes are fixedly connected to the end of the connecting plate away from the lifting rod.
[0017] Preferably, the vibration cleaning mechanism includes:
[0018] The vibration port is provided on the top of the base;
[0019] Vibratory machines, both of which are installed at the vibration port;
[0020] Vibrating plates are fixedly connected to the output ends of the two vibrators, and the dust collector body has a vibration port on the side facing the vibrator, and the two vibrating plates extend into the dust collector body through the vibration port.
[0021] A vibrating sleeve is fitted onto the outer side wall of the bottom of the plurality of filter bags, and one side of the vibrating sleeve is fixedly connected to one end of the vibrating plate that extends into the dust collector body.
[0022] Furthermore, there is a gap between the vibrating sleeve and the inner wall of the dust collector body.
[0023] Furthermore, the side extraction plate has a limiting plate at one end located inside the dust collector body.
[0024] Furthermore, a shock-absorbing pad is detachably connected to the connection between the vibrating plate and the dust collector body, and the shock-absorbing pad is made of rubber.
[0025] The working principle and beneficial effects of this utility model are as follows:
[0026] In this invention, after using the auxiliary cleaning device for the bag filter dust collector, the running device is shut down, and the air tank is pulled outward through the side extraction plate. Once pulled out to the point where the limit plate collides with the dust bag body, the lifting and cleaning mechanism is activated. The electric cylinder pushes out the lifting rod, causing the silicone brush to clean the inside of the bag back and forth. Then, the electric cylinder is shut down, and the vibrator is activated. The vibration generated by the vibrator is transmitted to the vibrating sleeve via the vibrating plate, causing multiple bags inside the dust collector to vibrate, dislodging some dust to the bottom or loosening it on the bags. The electric cylinder is activated again, causing the lifting rod to drive the silicone brush to rub and clean the inside of each bag back and forth. Some dust particles on the outside of the bags will fall directly to the bottom. Compared with existing technologies, using a silicone brush to clean the internal bags back and forth helps achieve the best cleaning effect each time the device is used. In particular, vibrating only the internal bags without direct contact with the overall equipment greatly reduces wear caused by friction, lowering maintenance costs and replacement frequency.

[0035] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0036] like Figures 1-6 As shown, this embodiment proposes an auxiliary dust removal device for a bag filter, including a dust collector body 1 and a sealing cover 2. Multiple filter bags 3 are disposed inside the dust collector body 1, and a base 4 is fixedly connected to the bottom of the dust collector body 1. The sealing cover 2 is detachably connected to the top of the dust collector body 1. It also includes a support 12, a lifting and sweeping mechanism, a vibration cleaning mechanism, a side extraction plate 5, and an air tank 6. The support 12 is fixedly connected to the top of the sealing cover 2. The lifting and sweeping mechanism is located on the top of the sealing cover 2 for auxiliary dust removal of the multiple filter bags 3. The vibration cleaning mechanism is located on the top of the base 4 for vibration cleaning of the multiple filter bags 3. The side extraction plate 5 is slidably connected to the outer wall of the dust collector body 1 near the sealing cover 2, and is used to pull it out so that the lifting and sweeping mechanism can descend. The air tank 6 is fixedly connected to the side extraction plate 5 for storing and releasing compressed air. A limit plate 7 is located at one end of the side extraction plate 5 inside the dust collector body 1 to ensure that the dust collector body 1 remains internally sealed under any conditions.
[0037] In this embodiment, the lifting and cleaning mechanism includes an electric cylinder 101, a lifting rod 102, a connecting plate 103, and silicone brushes 104. The electric cylinder 101 is installed on the top of the bracket 12, and a through hole is provided on the top of the sealing cover 2. The lifting rod 102 is fixedly connected to the output end of the electric cylinder 101, and the connecting plate 103 is fixedly connected to the other end of the lifting rod 102. Multiple silicone brushes 104 are fixedly connected to the end of the connecting plate 103 away from the lifting rod 102. The advantage of using silicone brushes 104 is that they can automatically stick to some dust and impurities, and they are less likely to damage the cloth bag 3. A short section of the silicone brush 104 is a smooth rod connected to the connecting plate 103, and the silicone brush passing through the through hole can fit snugly against the sealing cover 2, forming a sealed space inside.
[0038] In this embodiment, the vibration cleaning mechanism includes a vibration port 201, a vibrator 202, a vibrating plate 203, and a vibration sleeve 204. The top of the base 4 has a vibration port 201. Two vibrators 202 are installed at the vibration port 201, and a vibrating plate 203 is fixedly connected to the output end of each of the two vibrators 202. A vibration port is also provided on the side of the dust collector body 1 facing the vibrator 202, and the two vibrating plates 203 extend through the vibration port into the dust collector body 1. The vibration sleeve 204 is fitted onto the outer wall of the bottom of multiple filter bags 3, and one side of the vibration sleeve 204 extends into the vibrating plate 203. One end of the dust collector body 1 is fixedly connected, and there is a gap between the vibrating sleeve 204 and the inner wall of the dust collector body 1. The purpose is to prevent the vibration generated by the vibrator 202 from directly contacting the equipment body of the auxiliary dust cleaning device of the bag dust collector, so as to avoid wear on the equipment due to friction. The vibration plate 203 is detachably connected to the connection between it and the dust collector body 1 with a shock-absorbing pad 8. The shock-absorbing pad 8 is made of rubber, which is also to prevent direct friction between the equipment and the reverse vibration, reduce wear on the equipment due to vibration, and improve the stability of the equipment during operation. The rubber material has good sealing properties.
[0039] It should be added that the air inlet pipe 9 is connected to the dust collector body 1 and is located below the side extraction plate 5. The exhaust pipe 10 is located on the side of the dust collector body 1 away from the air inlet pipe 9. The dust hopper 11 is located at the bottom of the dust collector body 1. When the dust-laden gas enters the bag filter 3 dust collector, large dust particles settle into the dust hopper 11 under the action of gravity, while smaller dust particles are trapped when passing through the dust collector bags 3, thereby purifying the gas. However, as the filtration time increases, the dust layer on the bags 3 gradually thickens, causing the resistance of the dust collector to rise continuously. When the resistance reaches the set value, the dust removal process is mainly carried out by the compressed air in the air tank 6 rapidly expanding in the dust collector in a very short time, rushing into the bags 3, causing the bags 3 to vibrate and deform, thereby peeling off the dust attached to the outer surface of the bags 3 and letting it fall into the dust hopper 11.
[0040] In summary, the working principle of the auxiliary dust removal device for the bag filter is as follows: After cleaning using the auxiliary dust removal device, the clean gas filtered by the filter bags 3 is discharged through the exhaust pipe 10, while dust particles fall into the bottom ash hopper 11 due to gravity and are discharged from the ash hopper 11. As the dust layer on the filter bags 3 gradually thickens, it becomes difficult to achieve the best cleaning effect. At this point, the equipment can be shut down, and the electric cylinder 101 can be opened to extend the lifting rod 102, causing the lifting rod 102 to drive the silicone brush 104 down into each filter bag 3. The silicone brush 104 slides back and forth inside the filter bag 3 to achieve the cleaning effect. The electric cylinder 101 is then closed, and the two vibrators 202 are started to vibrate. Due to the dust on the filter bags 3... Since the structure is not made of very rigid material, strong vibration is not required. The vibration generated by the vibrator 202 is transmitted to the vibrating sleeve 204 through the vibrating plate 203. The vibrating sleeve 204, which is fitted on the filter bag 3, will cause the filter bag 3 to vibrate in a small range. During the vibration, it will not directly contact the dust collector body 1, which also reduces wear on the equipment. After being vibrated by the vibrator 202, the dust particles on the filter bag 3 will be loosened. At this time, the electric cylinder 101 will be started again to rub the silicone brush 104 inside each filter bag 3. The dust particles hanging on the outer wall of the filter bag 3 will fall directly into the ash hopper 11 and be discharged outward. The dust particles on the silicone brush 104 need to be removed by opening the sealing cover 2, cleaning or replacing the silicone brush 104, and then reused to complete the dust removal work.
[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
