Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, and more specifically, to a high-temperature resistant felt impregnated filter bag. Background Technology

[0002] With rapid economic development and the continuous improvement of people's living standards, the country has increasingly stringent requirements for air quality control, which also places higher demands on the performance and reliability of dust removal equipment. Filter bags have excellent chemical stability and heat resistance, making them the highest-performance representative in the filter media industry and the highest-end variety among all commonly used filter materials, achieving high levels in filtration efficiency and filtration accuracy.

[0003] A search revealed that Chinese utility model patent application number CN202021739615.3 discloses a high-temperature resistant felt impregnated filter bag, which includes a filter bag, three fixing devices and a clamping device. A stop block is inserted into the upper part of the right side wall of the filter bag, and an opening is opened at the bottom of the filter bag. Three nylon fabrics are inlaid inside the filter bag, and the three nylon fabrics are distributed from top to bottom. The fixing device includes a sealing bag and a ring rope. The sealing bag is sewn to the filter bag and forms a chamber between the sealing bag and the filter bag. The ring rope is located in the chamber.

[0004] During use, since the filter bags are directly installed on the corresponding pipes, the gas to be filtered enters the interior of the filter bags from the inside of the pipes. Because there is no corresponding structure on the pipes to clean the filter bags, dust will be adsorbed on the inner wall of the filter bags. Excessive dust adsorbed on the inner wall of the filter bags will cause them to become clogged, affecting the filtration effect. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a high-temperature resistant felt impregnated filter bag, which has the following characteristics:

[0018] Beneficial effects:

[0019] 1. The motor drives the square column to rotate, which in turn drives the rotating shaft and multiple soft nylon rods to rotate. Through centrifugal force, the soft nylon rods rotate and beat the filter bag, causing it to vibrate. This vibration of the filter bag dislodges the dust adsorbed on it, preventing clogging and ensuring the filtration effect and efficiency of the filter bag.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0033] Please see Figures 1-7A high-temperature resistant felt impregnated filter bag includes a filter bag 1, a connecting bag 2 fixedly connected to the top of the filter bag 1, a binding rope 3 passing through the inside of the connecting bag 2, a disc 4 inserted inside the filter bag 1, a rotating shaft 5 rotatably connected to the disc 4, a first circular groove 6 adapted to the rotating shaft 5 on the filter bag 1, the rotating shaft 5 passing through the inside of the first circular groove 6, a square groove 7 at the bottom of the rotating shaft 5, soft nylon rods 8 uniformly fixedly connected to the outside of the rotating shaft 5, a circular seat 9 at the bottom of the filter bag 1, a plurality of through-tubes 21 uniformly arranged on the outer side wall of the filter bag 1, a plurality of support rods 22 uniformly fixedly connected to the top of the circular seat 9, the plurality of support rods 22 being inserted into the interior of the plurality of through-tubes 21 respectively to facilitate support of the filter bag 1, the circular seat 9 being connected to the disc 4 through a connecting mechanism, a motor 10 being installed on the circular seat 9, the output shaft of the motor 10 being rotatably connected to the circular seat 9, and a square column 11 adapted to the square groove 7 being fixedly connected to the top of the output shaft of the motor 10.

[0034] Specifically, the motor 10 drives the square column 11 to rotate, which in turn drives the rotating shaft 5 and multiple soft nylon rods 8 to rotate. Through centrifugal force, the soft nylon rods 8 rotate and beat the filter bag 1, causing it to vibrate. This vibration removes the dust adsorbed on the filter bag 1, preventing clogging and ensuring the filtration effect and efficiency. Since the disc 4 and the round seat 9 are connected by a connecting mechanism, and the rotating shaft 5 is connected to the output shaft of the motor 10 through the square column 11, it is easy to disassemble and assemble the disc 4 and the round seat 9, and to remove and replace the filter bag 1.

[0035] Please see Figures 3-6 The connecting mechanism includes two connecting plates 12, which are fixedly connected to the bottom of the disc 4. The filter bag 1 is provided with two first through slots 13, and the round seat 9 is provided with a second through slot 14. The connecting plates 12 pass through the corresponding first through slots 13 and second through slots 14. The connecting plates 12 are provided with trapezoidal slots 15. The bottom of the disc 4 and the positions corresponding to the two second through slots 14 are fixedly connected with fixed plates 16. The fixed plates 16 are threaded with screws 17. The side end of the screws 17 is rotatably connected with trapezoidal plates 18 that are compatible with the trapezoidal slots 15. The side end of the trapezoidal plates 18 is fixedly connected with two positioning rods 19. The two positioning rods 19 are slidably engaged with the fixed plates 16 to facilitate positioning of the trapezoidal plates 18. The side end of the screws 17 is fixedly connected with a handle 20 to facilitate rotation of the screws 17.

[0036] Specifically, the connecting plate 12 passes through the corresponding first through groove 13 and second through groove 14, and then the screw 17 is rotated clockwise. The screw 17 moves relative to the fixed plate 16 towards the side closer to the connecting plate 12. The screw 17 drives the trapezoidal clamping plate 18 to move and inserts the trapezoidal clamping plate 18 into the trapezoidal slot 15. The inclined surface on the trapezoidal clamping plate 18 cooperates with the inclined surface on the trapezoidal slot 15 to squeeze the connecting plate 12 downward, thereby clamping the filter bag 1 between the disc 4 and the seat 9. This ensures the stability of the connection between the disc 4 and the seat 9 and the sealing of the connection between the disc 4 and the seat 9.

[0037] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 7 The circular base 9 is connected to a first discharge pipe 23, and a valve 24 is installed on the first discharge pipe 23. The disc 4 is connected to a second discharge pipe 25. The filter bag 1 is provided with a second circular groove 26. The second discharge pipe 25 passes through the inside of the second circular groove 26 and is inserted into the inside of the first discharge pipe 23. Multiple scrapers 27 are fixedly connected to the bottom side of the outer side of the rotating shaft 5. The bottom ends of the multiple scrapers 27 are in contact with the top of the disc 4, which facilitates the scraping off of dust on the disc 4 and facilitates the discharge of dust through the second discharge pipe 25 and the first discharge pipe 23.

[0038] Specifically, the second discharge pipe 25 is inserted into the interior of the first discharge pipe 23. When it is necessary to clean the dust inside the filter bag 1, the scraper 27 stirs the dust on the bottom side of the filter bag 1. The dust is discharged through the second discharge pipe 25 and the first discharge pipe 23, which makes it easier to clean the dust inside the filter bag 1.

[0039] In summary, when using the overall equipment:

[0040] The connecting bag 2 is placed on the corresponding pipe, and then the connecting bag 2 is securely tied to the corresponding pipe by the binding rope 3. The gas discharged from the inside of the pipe enters the inside of the filter bag 1, and the dust in the gas is filtered by the filter bag 1. At the same time, the motor 10 drives the square column 11 to rotate, and the square column 11 drives the rotating shaft 5 and multiple soft nylon rods 8 to rotate. Through centrifugal force, the soft nylon rods 8 will rotate and beat the filter bag 1, causing the filter bag 1 to vibrate. The vibration of the filter bag 1 can shake off the dust adsorbed on it. When it is necessary to clean the dust inside the filter bag 1, the valve 24 is opened, and the scraper 27 rotates with the rotating shaft 5. The scraper 27 stirs the dust on the bottom side of the inside of the filter bag 1, and the dust is discharged through the second discharge pipe 25 and the first discharge pipe 23.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
