Description

Technical Field

[0001] The present invention relates to the technical field of dust removal and filtration, and particularly to an environmental protection filtration device for industrial dust collectors. Background Art

[0002] A dust collector or dust removal equipment is a device that separates dust from flue gas. A bag filter, also known as a filter-type dust collector, is a dry and highly efficient dust collector. It is a dust removal device that uses a bag-type filter element made of fiber fabric to capture solid particles in the dust-containing gas. Its working principle is that dust particles are intercepted by colliding with fibers due to inertial force when they bypass the filter cloth fibers. In pulse and air box pulse dust collectors, the dust adheres to the outer surface of the filter bag. When the dust-containing gas passes through the dust collector, the dust is captured on the outer surface of the filter bag, and the clean gas enters the interior of the filter bag through the filter material. The cage inside the filter bag is used to support the filter bag to prevent it from collapsing. At the same time, it helps to remove and redistribute the dust cake.

[0003] A patent with the publication number of CN117298756A discloses a bag filter, which includes a dust removal box body. An upper fixing plate is fixedly installed inside the dust removal box body. A dust removal bag is installed inside the upper fixing plate. A lower fixing plate is installed below the dust removal bag. A lifting plate is installed below the upper fixing plate. A second connecting bearing corresponding to the dust removal bag one by one is installed inside the lifting plate. A rotating cylinder is installed inside the second connecting bearing. This bag filter is provided with a lifting plate that moves up and down, a rotating cylinder that rotates inside the lifting plate, and cleaning bristles. The two cooperate with each other to clean the outer surface of the working dust removal bag in real time, so that the dust removal bag is always in an effective filtering state, preventing the filtered dust from adhering to the surface of the dust removal bag under the action of air flow and wrapping the dust removal bag tightly, thereby affecting the dust removal efficiency of this bag filter.

[0004] However, the above-mentioned bag filter still has some deficiencies in actual use: The rotating cylinder drives the cleaning bristles to clean the surface of the dust removal bag. The adjusting motor and the power motor cooperate with each other to continuously sweep the dust adsorbed on the surface of the dust removal bag. However, in this way, when the dust collector is working continuously, the swept dust will quickly adhere to the surface of the dust removal bag due to the continuous intake of air, and the internal dust is very chaotic, resulting in low cleaning efficiency. Unless the dust collector stops working, therefore, an environmental protection filtration device for industrial dust collectors is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background art, and a proposed environmental protection filtration device for industrial dust collectors is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

A fixed slide rod is slidably connected to the outer wall of the first slide rail. The fixed slide rod is fixedly connected to the anti-escaping chamber.

[0009] In the above-mentioned environmental protection filtering device for an industrial dust collector, a first connecting rod is fixedly connected to the outer wall of the first slide rod. A multi-section telescopic rod is fixedly connected to the outer wall of the first connecting rod. A third shaft rod is fixedly connected to the outer wall of the multi-section telescopic rod. One end of the third shaft rod far away from the multi-section telescopic rod is connected to a fourth gear through a one-way bearing. A second slide rail is slidably connected to the outer wall of the third shaft rod. A tooth block group is fixedly connected to the outer wall of the second slide rail. The tooth block group meshes with the fourth gear. A fixed frame is fixedly connected to the outer wall of the second slide rail. The fixed frame is fixedly connected to the anti-escaping chamber.

[0010] In the above-mentioned environmental protection filtering device for an industrial dust collector, a first spring is fixedly connected between the first sliding rod and the sliding cylinder. The outer walls of the four first gears are jointly sleeved with the same chain. Three limiting plates are fixedly connected to the outer wall of the anti-diffusion cavity. Two evenly distributed dust collecting rods are fixedly connected to the bottom outer wall of each cleaning brush plate.

[0011] In the above-mentioned environmental protection filtering device for an industrial dust collector, each rotating disk is movably connected with a transmission belt through a provided shaft rod. A third gear is arranged below each rotating disk. The third gear is movably connected with the inner wall of the other end of the transmission belt through a provided shaft rod.

[0012] In the above-mentioned environmental protection filtering device for an industrial dust collector, a second gear is meshed with the outer wall of each third gear. A second shaft rod is fixedly connected to the outer wall of the second gear. The second shaft rod is rotatably connected with the inner wall of the anti-diffusion cavity. A bidirectional threaded rod is fixedly connected to the outer wall of the second gear on the side away from the second shaft rod.

[0013] In the above-mentioned environmental protection filtering device for an industrial dust collector, a second connecting rod is fixedly connected to the top outer wall of the connecting block. An inclined plane slider is fixedly connected to the outer wall of the second connecting rod. The inclined plane slider is slidably connected with the inner wall of the anti-diffusion cavity. A second spring is fixedly connected to the inner wall of the inclined plane slider. An arc-shaped plate is fixedly connected to the outer wall of the second spring. A rotating seat is rotatably connected to the outer wall of the arc-shaped plate. The rotating seat is fixedly connected with the inclined plane slider.

[0014] In the above-mentioned environmental protection filtering device for an industrial dust collector, six evenly distributed turnover plates are arranged at the bottom of each anti-diffusion cavity.

[0015] Compared with the existing technology, the beneficial effects of the environmental protection filtering device for an industrial dust collector of the present invention are as follows:

[0016] 1. During the downward movement of the cleaning brush plate, the cleaning brush plate sweeps the dust on the outer wall of the dust removal cloth bag. The dust falls on the arc-shaped plate as the cleaning brush plate moves downward, and then falls along the slope of the arc-shaped plate to the junction of the arc-shaped plate and the anti-diffusion cavity. When the third shaft rod moves to the inclined surface below the second slide rail, the cleaning brush plate will move away from the dust removal cloth bag and press down, so that the cleaning brush plate sweeps the swept dust into the anti-diffusion cavity, and the dust collecting rod will squeeze the arc-shaped plate so that the bottom surface of the arc-shaped plate rotates with the rotating seat. The bottom surface of the arc-shaped plate is closely attached to the inclined surface of the inclined surface slider, so that the dust falls into the inner wall of the anti-diffusion cavity, completing the collection of dust and preventing dust from escaping;

[0017] 2. When the cleaning brush plate moves downward, the inclined surface slider can drive the arc-shaped plate to always be below the cleaning brush plate to receive dust, avoiding the escape of dust everywhere;

[0018] 3. When the cleaning brush plate moves upward away from the dust removal cloth bag, the second connecting rod also moves with the cleaning brush plate to the side away from the dust removal cloth bag, so that when the dust removal telescopic rod moves downward, it prevents the arc-shaped plate from scraping off the dust that has not been cleaned on the outer wall of the dust removal cloth bag, causing the disorder of the internal dust;

[0019] In summary, in the process of cleaning the dust on the outer wall of the entire dust removal cloth bag of the present invention, there is no need to close the air inlet, and the dust is always restricted by the cleaning brush plate and the annular cleaning cavity, ensuring the cleaning of the outer wall of the circular dust removal cloth bag. After the dust falls into the anti-diffusion cavity, the arc-shaped plate immediately closes to prevent the escape of dust, avoiding the redeposition of the cleaned dust on the outer wall of the dust removal cloth bag, and the dust collector can work continuously. The swept dust is always restricted until it is collected. Description of the Drawings

The cleaning brush plate 15 is fixedly connected to the slide rail 22. The slide rod 21 is slidably connected to the slide rail 22. The slide rod 21 is slidably connected to the sliding cylinder 46. The sliding cylinder 46 is fixedly connected to the rotating disc 26. The rotating disc 26 is fixedly connected to the gear 28 through a set shaft rod. Three of the gears 28 are rotatably connected to the inner wall of the annular cleaning chamber 14 through a set shaft rod. A motor 29 is fixedly connected to the outer wall of the other gear 28. The motor 29 is rotatably connected to the inner wall of the annular cleaning chamber 14. A fixed slide rod 48 is slidably connected to the outer wall of the slide rail 22. The fixed slide rod 48 is fixedly connected to the anti-escaping chamber 16.

[0036] In this embodiment, the gas containing dust enters the interior of the dust removal chamber 3 from the air inlet 1. When a certain amount of dust accumulates on the outer wall of the dust removal cloth bag 9 and needs to be cleaned, the four dust removal telescopic rods 2 move downward. The dust removal telescopic rods 2 drive all the annular cleaning chambers 14 and the anti-escaping chambers 16 to move downward through the cleaning plate 8. At the same time, the motor 29 starts to rotate, so that the motor 29 drives all the rotating discs 26 to rotate through the gear 28 and the chain 18. The rotating disc 26 drives the slide rail 22 and the cleaning brush plate 15 to move up and down through the sliding cylinder 46 and the slide rod 21. During the downward movement of the cleaning brush plate 15, the cleaning brush plate 15 sweeps the dust on the outer wall of the dust removal cloth bag 9.

[0037] Wherein, a first connecting rod 20 is fixedly connected to the outer wall of the first sliding rod 21. A multi-section telescopic rod 23 is fixedly connected to the outer wall of the first connecting rod 20. A third shaft rod 42 is fixedly connected to the outer wall of the multi-section telescopic rod 23. One end of the third shaft rod 42 away from the multi-section telescopic rod 23 is connected to a fourth gear 41 through a one-way bearing. A second slide rail 25 is slidably connected to the outer wall of the third shaft rod 42. A tooth block group 40 is fixedly connected to the outer wall of the second slide rail 25. The tooth block group 40 meshes with the fourth gear 41. A fixing frame 24 is fixedly connected to the outer wall of the second slide rail 25.

Two evenly distributed dust collecting rods 47 are fixedly connected to the bottom outer wall of each cleaning brush plate 15.

[0038] In this embodiment, dust falls on the arc-shaped plate 19 as the cleaning brush plate 15 moves downward, and then falls along the slope of the arc-shaped plate 19 to the junction of the arc-shaped plate 19 and the anti-diffusion chamber 16. When the third shaft rod 42 moves to the inclined surface below the second slide rail 25, the cleaning brush plate 15 will move away from the dust removal cloth bag 9 and press downward, so that the cleaning brush plate 15 sweeps the swept dust into the anti-diffusion chamber 16, and the dust collecting rod 47 will squeeze the arc-shaped plate 19 to make the bottom surface of the arc-shaped plate 19 rotate with the rotating seat 45. The bottom surface of the arc-shaped plate 19 is closely attached to the inclined surface of the inclined surface slider 31, so that the dust falls into the inner wall of the anti-diffusion chamber 16, completing the collection of dust and preventing the dust from escaping.

[0039] Wherein, each rotating disk 26 is movably connected to a transmission belt 27 through a provided shaft rod. A third gear 39 is arranged below each rotating disk 26. The third gear 39 is movably connected to the inner wall of the other end of the transmission belt 27 through a provided shaft rod. The third gear 39 is rotatably connected to the inner wall of the anti-diffusion chamber 16 through a provided shaft rod. A second gear 37 meshes with the outer wall of each third gear 39. A second shaft rod 38 is fixedly connected to the outer wall of the second gear 37. The second shaft rod 38 is rotatably connected to the inner wall of the anti-diffusion chamber 16. A bidirectional threaded rod 36 is fixedly connected to the outer wall of the second gear 37 away from the second shaft rod 38. A connecting block 35 is threadedly connected to the outer wall of the bidirectional threaded rod 36.

[0040] In the present embodiment, during the rotation of the rotating disk 26, the rotating disk 26 drives the gear three 39 to rotate through the transmission belt 27, and the gear three 39 drives the connecting block 35 and the connecting rod two 43 to move through the bidirectional threaded rod 36, so that when the cleaning brush plate 15 moves down, the inclined slider 31 can carry the arc plate 19 to be always located below the cleaning brush plate 15 to receive the dust, and when the cleaning brush plate 15 moves up away from the dust bag 9, the connecting rod two 43 also moves with the cleaning brush plate 15 to the side away from the dust bag 9, so that when the dust removal telescopic rod 2 moves down, the arc plate 19 is prevented from scraping off the dust that is not cleaned on the outer wall of the dust bag 9.

[0041] Among them, the top outer wall of the connecting block 35 is fixedly connected with a connecting rod 2 43, the outer wall of the connecting rod 2 43 is fixedly connected with a sloped slider 31, the sloped slider 31 is slidably connected to the inner wall of the anti-escape cavity 16, the inner wall of the sloped slider 31 is fixedly connected with a spring 2 44, the outer wall of the spring 2 44 is fixedly connected with an arc plate 19, the outer wall of the arc plate 19 is rotatably connected with a rotating seat 45, the rotating seat 45 is fixedly connected to the sloped slider 31, and six evenly distributed flip plates 30 are provided at the bottom of each anti-escape cavity 16, the inner wall of each flip plate 30 is fixedly connected with a first shaft rod 33, and both ends of each first shaft rod 33 are fixedly connected with a torsion spring 34, and the end of each torsion spring 34 away from the flip plate 30 is fixedly connected to the anti-escape cavity 16.

[0042] In the present embodiment, after the outer wall of the dust bag 9 is cleaned, the insertion rod 11 abuts against the flip plate 30, causing the flip plate 30 to reverse, thereby pouring the dust in the anti-escape chamber 16 into the dust collecting chamber 6 for collection. The entire process of cleaning the dust on the outer wall of the dust bag 9 does not require closing the air inlet 1, and the dust is always restricted by the cleaning brush plate 15 and the annular cleaning chamber 14, ensuring the cleaning of the outer wall of the circular dust bag 9. After the dust falls into the anti-escape chamber 16, the arc plate 19 is immediately closed to prevent the escape of dust and to prevent the cleaned dust from re-attaching to the outer wall of the dust bag 9.

[0043] The specific working principle and usage method of the present invention will be explained in detail as follows: When in use, the gas containing dust enters the interior of the dust removal chamber 3 from the air inlet 1. When a certain amount of dust accumulates on the outer wall of the dust removal cloth bag 9 and needs to be cleaned, the four dust removal telescopic rods 2 move downward. The dust removal telescopic rods 2 drive all the annular cleaning chambers 14 and the anti-diffusion chambers 16 to move downward through the cleaning plate 8. At the same time, the motor 29 starts to rotate, so that the motor 29 drives all the rotating disks 26 to rotate through the first gear 28 and the chain 18. The rotating disks 26 drive the slide rail 22 and the cleaning brush plate 15 to move up and down through the sliding cylinder 46 and the first slide rod 21. During the downward movement of the cleaning brush plate 15, the cleaning brush plate 15 sweeps the dust on the outer wall of the dust removal cloth bag 9. The dust falls on the arc plate 19 as the cleaning brush plate 15 moves downward and then falls along the slope of the arc plate 19 to the junction of the arc plate 19 and the anti-diffusion chamber 16. When the third shaft rod 42 moves to the inclined surface below the second slide rail 25, the cleaning brush plate 15 will move away from the dust removal cloth bag 9 and press down, so that the cleaning brush plate 15 sweeps the swept dust into the anti-diffusion chamber 16, and the dust collecting rod 47 will squeeze the arc plate 19 to make the bottom surface of the arc plate 19 rotate with the rotating seat 45. The bottom surface of the arc plate 19 is closely attached to the inclined surface of the inclined surface slider 31, so that the dust falls into the inner wall of the anti-diffusion chamber 16, completing the collection of dust and preventing the dust from escaping.

[0044] At the same time, during the rotation of the rotating disk 26, the rotating disk 26 drives the third gear 39 to rotate through the transmission belt 27. The third gear 39 drives the connecting block 35 and the second connecting rod 43 to move through the bidirectional threaded rod 36, so that when the cleaning brush plate 15 moves downward, the inclined surface slider 31 can drive the arc plate 19 to always be below the cleaning brush plate 15 to receive the dust. When the cleaning brush plate 15 moves upward away from the dust removal cloth bag 9, the second connecting rod 43 also moves to the side away from the dust removal cloth bag 9 along with the cleaning brush plate 15, so that when the dust removal telescopic rod 2 moves downward, it prevents the arc plate 19 from scraping off the dust on the outer wall of the dust removal cloth bag 9 that has not been cleaned.

[0045] After the outer wall of the dust removal cloth bag 9 is cleaned, the insertion rod 11 touches the turning plate 30, causing the turning plate 30 to reverse, so that the dust in the anti-diffusion chamber 16 is poured into the dust collection chamber 6 for collection. The process of cleaning the dust on the outer wall of the entire dust removal cloth bag 9 does not require closing the air inlet 1, and the dust is always restricted by the cleaning brush plate 15 and the annular cleaning chamber 14, ensuring the cleaning of the outer wall of the circular dust removal cloth bag 9. After the dust falls into the anti-diffusion chamber 16, the arc plate 19 immediately closes to prevent the dust from escaping and avoid the cleaned dust from reattaching to the outer wall of the dust removal cloth bag 9.

[0046] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0047] As described above, it is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
