Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figure 1 - Figure 6As shown, this invention is a dust removal device for an air filter, including a dust removal platform 1. A mounting frame 2 is fixedly installed on the top surface of the dust removal platform 1. The main components of the air filter are the filter element and the housing. The filter element is the main filtration part, responsible for filtering the gas, while the housing is the external structure that provides necessary protection for the filter element. A rectangular through hole 3 is provided on the side of the dust removal platform 1 near the mounting frame 2. The rectangular through hole 3 is used to install a first conveyor belt 42. A dust removal assembly 4 is provided on the dust removal platform 1. The dust removal assembly 4 includes a dust removal needle plate 48, which is installed on the side of the mounting frame 2 near the rectangular through hole 3. The dust removal needle plate 48 is made of a soft material to minimize damage to the filter element. The side of the dust removal platform 1 near the mounting frame 2 is divided into... A fixing block 43 and a fixing plate 44 are fixedly installed. A first conveyor belt 42 is rotatably installed between the fixing block 43 and the fixing plate 44. The filter element is placed on the first conveyor belt 42, so that the filter element rotates at a time under the drive of the first conveyor belt 42. A stop bar 41 is fixedly installed in the rectangular through hole 3. A rotating plate 411 is rotatably installed on the side of the fixing block 43 away from the first conveyor belt 42. The rotating plate 411 serves to drive the first conveyor belt 42 to rotate at a time. The rotating plate 411 has a crescent groove 412 and a U-shaped groove 47, which are staggered on the rotating plate 411. A first motor 46 is fixedly installed on the side of the dust removal table 1 near the rotating plate 411. A crescent-shaped circle 45 is fixedly installed on the output end of the conveyor belt 42. A connecting plate 49 is fixedly installed on the side of the crescent-shaped circle 45 near the fixed block 43. A rotating column 410 is fixedly installed on the end of the connecting plate 49 away from the crescent-shaped circle 45. The connecting plate 49 is slidably installed in the U-shaped groove 47, and the crescent-shaped circle 45 is slidably installed in the crescent-shaped groove 412. The first motor 46 drives the crescent-shaped circle 45 to rotate in the crescent-shaped groove 412 through the output end. At the same time, the crescent-shaped circle 45 drives the rotating column 410 to rotate in the U-shaped groove 47 through the connecting plate 49. Simultaneously, the rotating column 410 drives the rotating plate 411 to rotate one-quarter of the way. This reciprocating motion drives the first conveyor belt 42 to rotate at a fixed rate. 42 drives the filter element to rotate periodically, and then the dust removal needle plate 48 is activated to remove dust from the filter element periodically. The baffle 41 is installed above the first conveyor belt 42 to facilitate the compression of the first conveyor belt 42 into a "V" shape. The cross-section of the first conveyor belt 42 is "V" shaped. The rotating shaft of the rotating plate 411 slides through the fixed block 43 and is fixedly installed on the drive shaft of the first conveyor belt 42. There are two fixed blocks 43 and one fixed plate 44. The rotating plate 411 is installed on one of the fixed blocks 43. When using the device, first place the filter element on the first conveyor belt 42 and simultaneously fit the filter element onto the collecting plate 69. Then start the first motor 46, so that the output end of the first motor 46 drives the crescent circle 45 to rotate in the crescent groove 412.Simultaneously, the crescent-shaped ring 45, via the connecting plate 49, drives the rotating column 410 to slide within the U-shaped groove 47. The rotating column 410, in turn, drives the rotating plate 411 to rotate. The rotating plate 411, in turn, drives the first conveyor belt 42 to rotate on the stop bar 41. Simultaneously, the first conveyor belt 42 drives the filter element to rotate on the collection plate 69. At the same time, the electric telescopic rod 51, via the mounting plate 52, moves the dust-collecting needle plate 48 towards the filter element, allowing the dust-collecting needle plate 48 to easily push out dust from inside the filter element. The pushed-out dust falls onto the collection plate 69, facilitating the rotation and dust collection of the filter element on the collection plate 69. This facilitates timed rotation and dust collection, effectively removing dust that is difficult to clean from inside the filter element, minimizing damage to the filter element, extending its service life, improving the dust collection effect of the device, and increasing the overall efficiency of the dust collection process.

[0032] Please see Figure 3 - Figure 6 As shown, based on Embodiment 1, a limiting component 5 is provided on the mounting frame 2. The limiting component 5 includes a limiting plate 55. An electric telescopic rod 51 is fixedly installed on the side of the mounting frame 2 near the first conveyor belt 42. The electric telescopic rod 51 drives the dust removal needle plate 48 to move up and down, facilitating the removal of dust from the filter element. An mounting plate 52 is fixedly installed on the end of the electric telescopic rod 51 away from the mounting frame 2. A groove 53 is provided on the mounting plate 52, and a protrusion 56 is slidably installed in the groove 53 for easy installation and disassembly. The dust removal needle plate 48 is fixedly installed on the side of the protrusion 56 away from the mounting plate 52. The limiting plate 55 is rotatably installed on the side of the mounting plate 52 near the groove 53. The limiting plate 55 serves to limit and stabilize the protrusion 56. The limiting plate 55 is rotatably mounted on both ends of the mounting plate 52. The mounting plate 52, near the electric telescopic rod 51, has screws 54 threaded onto both ends. These screws 54 limit and fix the protrusion 56. When using the device, first move the dust removal needle plate 48, simultaneously causing it to drive the protrusion 56 into the groove 53. Then rotate the limiting plate 55 onto the protrusion 56, and then tighten the screws 54, causing them to press against the protrusion 56 in the groove 53, thus limiting and fixing the protrusion 56. This facilitates installation and disassembly, makes it easier to replace damaged dust removal needle plates 48, improves the dust removal effect of the dust removal needle plates 48, and increases the efficiency of device installation and disassembly.

The output end of the second motor 66 drives the second conveyor belt 65 to rotate, which facilitates the transportation of dust collected on the second conveyor belt 65 into the dust collection box 67, making collection operations convenient. The output end of the second motor 66 slides through the collection plate 69 and is fixedly installed on the second conveyor belt 65. On the drive shaft with 65, a blower 610 is fixedly installed on the side of the dust collection table 1 near the support plate 68. A ventilation pipe 612 is connected to the side of the blower 610 away from the dust collection table 1. The end of the ventilation pipe 612 away from the blower 610 is connected to the inside of the collection plate 69. Air outlets 611 are opened on both sides of the collection plate 69. An air outlet pipe is installed inside the collection plate 69, and the air outlet pipe connects the air outlet 611 and the ventilation pipe 612. The blower 610 blows air into the collection plate 69 through the ventilation pipe 612, and at the same time, the air from the air outlet 611 removes dust from the filter element. When using the device, first start the exhaust pump 62, the second motor 66 and the blower 610, and simultaneously start the output of the second motor 66. The first end drives the second conveyor belt 65 to rotate, and at the same time, the second conveyor belt 65 transports the removed dust to the dust collection box 67. Simultaneously, the blower 610 blows air into the collection plate 69 through the ventilation pipe 612, and the air is also used to remove dust from the filter element through the air outlet 611. At the same time, the exhaust pump 62 uses the exhaust pipe 63 and the exhaust hood 64 to exhaust and recover the dust blown out of the air outlet 611. The air carrying dust is also purified in the purifier 61. This makes it convenient to operate and use, and facilitates further dust removal of the filter element. It not only makes it convenient to collect dust, but also improves the dust removal efficiency of the device, which is beneficial to improving the dust removal efficiency of the device and the overall working efficiency of the device.

[0035] Example 4

[0036] Please see Figure 1 - Figure 6As shown, this embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3. The dust removal needle plate 48 is installed on the mounting frame 2 by the limiting component 5. Then the filter element is placed on the first conveyor belt 42. Then the first motor 46 is started to drive the filter element on the first conveyor belt 42 to rotate at regular intervals. At the same time, the electric telescopic rod 51 is started to drive the dust removal needle plate 48 to remove dust from the filter element. At the same time, the dust removal component 6 is started to collect and recycle the removed dust.

[0037] The working principle of this invention is as follows: When using the device, first, move the dust removal needle plate 48, and simultaneously, move the dust removal needle plate 48 to insert the protrusion 56 into the groove 53. Then, rotate the limiting plate 55 onto the protrusion 56, and then tighten the fixing screw 54 to press the protrusion 56 in the groove 53. Then, place the filter element on the first conveyor belt 42, and simultaneously, fit the filter element onto the collecting plate 69. Then, start the first motor 46, and make the output end of the first motor 46 drive the crescent circle 45 to rotate in the crescent groove 412. At the same time, the crescent circle 45 drives the rotating column 410 to slide in the U-shaped groove 47 through the connecting plate 49. Simultaneously, the rotating column 410 drives the rotating plate 411 to rotate, and the rotating plate 411 drives the first conveyor belt 42 to rotate on the stop bar 41. The filter element rotates on the collection plate 69. At the same time, the electric telescopic rod 51 is activated, which drives the dust removal needle plate 48 to move towards the filter element through the mounting plate 52. This allows the dust removal needle plate 48 to easily push the dust out of the filter element. The pushed-out dust falls onto the collection plate 69. Then, the exhaust pump 62, the second motor 66, and the blower 610 are activated. At the same time, the output end of the second motor 66 drives the second conveyor belt 65 to rotate. The second conveyor belt 65 transports the removed dust into the dust collection box 67. Meanwhile, the blower 610 blows air into the collection plate 69 through the ventilation pipe 612. At the same time, the air removes dust from the filter element through the air outlet 611. Simultaneously, the exhaust pump 62 draws in the dust blown out of the air outlet 611 through the exhaust pipe 63 and the exhaust hood 64. At the same time, the air carrying the dust is purified in the purifier 61.
