Description

Technical Field

[0001] The invention relates to the technical field of gas filtration, and in particular to a device for air pollution control. Background Art

[0002] Air pollution directly affects the quality of life and health of human beings. Long-term exposure to polluted air increases the risk of respiratory diseases, cardiovascular diseases and other diseases, and may even lead to death in severe cases. At the same time, air pollution will also destroy the ecological balance, affect natural elements such as climate, water bodies, and soil, and have a long-term impact on the global environment. Therefore, air pollution control is an important measure to protect public health, promote sustainable development and maintain ecological balance. In related technologies, air filtration equipment can filter dust in the air, thereby improving air quality.

[0003] The Chinese patent with the authorization announcement number CN115318025B discloses a self-cleaning air filter device for air pollution prevention and control, which includes a housing, a support assembly, a filter plate, a scraper, an adjustment structure and a drive structure. The support assembly includes a first connecting member, a second connecting member and a bracket.

[0004] In the above patent, when dust accumulates in front of the filter plate, the first connecting piece moves backward under the action of wind, and the vertical distance between the bracket and the filter plate is reduced. The adjusting structure drives the scraper to quickly approach the filter plate until the two are abutted, and the driving structure drives the scraper to move from the second end to the first end to scrape the dust to the first connecting piece. In the absence of workers to clean, the filtering device can also automatically complete the cleaning work to avoid clogging of the filter plate, thereby preventing the subsequent filtering work and filtering effect from being affected by the clogging of the filter plate.

[0005] However, the above patent will inevitably generate dust during the dust cleaning process, and the filter plate needs to be cleaned frequently during dust removal. The filter plate may be broken after being scraped and cleaned many times, resulting in reduced dust removal effect. Summary of the invention

[0006] The present invention provides a device for air pollution control, aiming to solve the problem in the related art that a filter plate may be broken after being scraped and cleaned for many times, resulting in reduced dust removal effect.

[0007] The device for air pollution control of the present invention comprises: a frame and a filter assembly;

[0008] A partition is provided in the frame, and a conveyor belt is slidably matched on the partition, and the conveyor belt abuts against the top surface of the partition. The conveyor belt divides the interior of the frame into an upper chamber and a lower chamber, and an air inlet and an air outlet are respectively provided at both ends of the upper chamber;

[0009] The filter assembly includes a filter frame, a filter plate, a sliding frame and a driving mechanism, the filter frame is fixedly connected to the conveyor belt, the filter plate and the sliding frame are both slidably fitted in the filter frame, and the filter plate and the sliding frame are spaced apart and connected by a first elastic member, the sliding frame is connected to the filter frame by a second elastic member, a plurality of blades are rotatably connected in the sliding frame, the plurality of blades form a louver structure, the driving mechanism is arranged on the sliding frame, the driving mechanism is used to drive the blades to rotate, a limit block is provided on the sliding frame, the frame is provided with a stop block in the lower chamber, the stop block is connected to the frame by a third elastic member, and the stop block can stop against the limit block.

[0010] Beneficial effect: when the filter mechanism is located in the lower chamber, the blades are in a closed state, and when the limit block and the stop block are stopped, the stop block hinders the limit block, so that the sliding frame moves relative to the filter frame, the second elastic member contracts, and the first elastic member stretches. When the first elastic member stretches to a natural state, the sliding frame drives the filter plate to move through the first elastic member. When the sliding frame moves to stop with the filter frame, the limit block squeezes the stop block, so that the third elastic member contracts, and the stop block is pressed into the frame body. The second elastic member releases the elastic force and pushes the sliding frame to move quickly to the right, and the filter plate and the sliding frame move to the right synchronously. When the filter plate and the filter frame stop, the filter plate vibrates due to the collision, and the particles attached to the filter plate are shaken off by vibration. At this time, the sliding frame continues to move, and the closed louver structure squeezes the air between the blade and the filter plate. The remaining particles attached to the filter plate can be taken away by airflow, and the particles scattered on the filter frame can be blown away from the filter frame.

[0011] Preferably, there are a plurality of filter assemblies, and the plurality of filter assemblies are distributed at intervals on the conveyor belt, and at least two of the filter assemblies are present in the upper chamber at the same time.

[0012] The effect is that during the filtering process, at least two filter components are always maintained in the upper chamber, thereby preventing the filter plate in a filter component from being damaged, resulting in reduced filtering effect.

[0013] Preferably, the driving mechanism includes a driving gear and a driving rod, the driving gear is fixedly connected to each of the blades, the driving rod is slidably fitted on the sliding frame, and is connected to the sliding frame through a fourth elastic member, a tooth groove is provided on the driving rod, the driving rod is meshed with the driving gear, and the driving rod can extend out of the sliding frame.

[0014] Preferably, a sliding groove is provided at the top end of the partition, and a plurality of spaced limiting protrusions are provided in the sliding groove, and the driving rod can extend into the sliding groove and slideably cooperate with the sliding groove.

[0015] The effect is that when the filter assembly moves in the upper chamber, the drive rod can extend into the sliding groove and move along the sliding groove. When the drive rod stops with the limiting protrusion, the limiting protrusion can squeeze the drive rod, so that the drive rod moves relative to the sliding frame, and the drive rod drives the drive gear to rotate, thereby driving the blades to rotate. When the drive rod passes over the limiting protrusion, it is reset under the action of the fourth elastic member, and drives the blades to rotate in the opposite direction through the driving gear. The blades can swing periodically during the movement of the filter assembly, so that the airflow is evenly distributed on the filter plate of the next filter assembly, thereby preventing a large amount of dust from being concentrated in a certain area on the filter plate, causing the filter plate to be blocked.

[0016] Preferably, sealing components are provided on both sides of the conveyor belt, and the sealing components are used to isolate the upper chamber and the lower chamber.

[0017] The effect is that the sealing component can isolate the upper chamber from the lower chamber, preventing dust generated in the lower chamber during the cleaning process of the filter component from flowing into the upper chamber and affecting the quality of the purified air.

[0018] Preferably, the sealing assembly includes a first sealing plate and a second sealing plate, the second sealing plates are spaced apart from each other in the upper and lower directions, one end of the first sealing plate is rotatably engaged with the frame, and the other end thereof is stopped against the conveyor belt, one end of the second sealing plate is rotatably engaged with the frame, and the other end thereof is stopped against the conveyor belt, and a sealed compartment is formed between the second sealing plates.

[0019] Preferably, an ash discharge port is provided at the bottom of the lower chamber.

[0020] The effect is that the provision of the ash discharge port can prevent the microparticles from gathering in the lower chamber.

[0021] Preferably, the bottom of the lower chamber is a funnel structure, and the ash discharge port is located at the bottom end of the funnel structure.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are:

[0023] According to the device for air pollution control of the present invention, when the filter mechanism is located in the lower chamber, the blades are in a closed state, when the limit block and the stop block are stopped, the stop block hinders the limit block, so that the sliding frame moves relative to the filter frame, the second elastic member contracts, and the first elastic member stretches. When the first elastic member stretches to a natural state, the sliding frame drives the filter plate to move through the first elastic member. When the sliding frame moves to stop with the filter frame, the limit block squeezes the stop block, so that the third elastic member contracts, and the stop block is pressed into the frame body. The second elastic member releases the elastic force and pushes the sliding frame to move quickly to the right, and the filter plate and the sliding frame move to the right synchronously. When the filter plate and the filter frame stop, the filter plate vibrates due to the collision, and the particles attached to the filter plate are shaken off by the vibration. At this time, the sliding frame continues to move, and the closed shutter structure squeezes the air between the blade and the filter plate. The remaining particles attached to the filter plate can be taken away by the airflow, and the particles scattered on the filter frame are blown away from the filter frame. While improving the cleaning effect of the filter mechanism, the filter plate will not be damaged, and the service life of the filter plate is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 7 As shown, the device for air pollution control of the present invention includes: a frame 1 and a filter assembly 5.

[0035] Specifically, Figure 1 and Figure 2 As shown, a partition 2 is provided inside the frame 1, and a conveyor belt 3 is slidably matched with the partition 2, and the top surface of the partition 2 abuts against the conveyor belt 3. A first driving member 4 is provided outside the frame 1, and the first driving member 4 is a motor, which is used to drive the conveyor belt 3 to rotate inside the frame 1. The conveyor belt 3 divides the inside of the frame 1 into an upper chamber and a lower chamber. An air inlet 13 is provided on the left side of the upper chamber, and an air outlet 14 is provided on the right side thereof. The bottom of the lower chamber is a funnel-shaped structure, and an ash discharge port 12 is provided at the bottom end of the funnel-shaped structure.

[0036] like Figures 2 to 6As shown, a plurality of filter assemblies 5 are evenly spaced and distributed on the conveyor belt 3. The filter assembly 5 includes a filter frame 51, a filter plate 52, a sliding frame 53 and a driving mechanism. The filter frame 51 is fixedly connected to the conveyor belt 3. The outer wall of the filter frame 51 is in contact with and slides with the inner wall of the upper chamber. The filter plate 52 and the sliding frame 53 are both slidably fitted in the filter frame 51. The filter plate 52 and the sliding frame 53 are spaced and distributed, and the two are elastically connected by a first elastic member 54, which is a spring connecting rod. The sliding frame 53 is elastically connected to the filter frame 51 by a second elastic member 55, which is a spring. A limiting groove is also provided on the filter frame 51, which can stop against the filter plate 52 to prevent the filter plate 52 from detaching from the filter frame 51. The sliding frame 53 is provided with a plurality of blades 56 evenly spaced up and down, and the plurality of blades 56 form a shutter structure. The blades 56 are rotatably matched with the sliding frame 53. The driving mechanism includes a driving gear 61 and a driving rod 62. Each blade 56 is fixedly connected with a driving gear 61. The driving rod 62 is slidably matched in the sliding frame 53 and elastically connected with the sliding frame 53 through a fourth elastic member 63, which is a spring. The driving rod 62 is provided with a rack, and the driving rod 62 is meshed with the driving gear 61 through the rack. The driving rod 62 can extend out of the sliding frame 53 and stop against the top surface of the partition 2. The sliding frame is provided with two spaced limit blocks 531. The frame 1 is provided with a plurality of stop blocks 7 in the lower chamber. The plurality of stop blocks 7 are evenly spaced in the horizontal direction, and each stop block 7 is elastically connected with the frame 1 through a third elastic member 8, which is a spring. The stop block 7 can be received in the frame 1, and the limit block 531 can stop against the stop block 7.

[0037] like Figure 2 , Figure 6 and Figure 7 As shown, a sliding groove 9 is also provided on the partition 2, and a plurality of spaced limiting protrusions 10 are provided on the sliding groove 9. When the filter assembly 5 moves from right to left in the upper chamber, the driving rod 62 can extend into the sliding groove 9 and move along the sliding groove 9. When the driving rod 62 stops against the limiting protrusion 10, the limiting protrusion 10 can squeeze the driving rod 62, so that the driving rod 62 moves relative to the sliding frame 53, and the driving rod 62 drives the driving gear 61 to rotate, thereby driving the blade 56 to rotate. After the driving rod 62 passes over the limiting protrusion 10, it is reset under the action of the fourth elastic member 63, and drives the blade 56 to rotate in the opposite direction through the driving gear 61, so that the blade 56 can swing periodically during the process of the filter assembly 5 moving from right to left, so that the airflow is evenly distributed on the filter plate 52 of the next filter assembly 5, so as to prevent a large amount of dust from being concentrated in a certain area on the filter plate 52, causing the filter plate 52 to be blocked.

[0038] like Figure 1 and Figure 2As shown, sealing assemblies are provided on both sides of the conveyor belt 3, and the sealing assemblies include a first sealing plate 111 and a second sealing plate 112. One end of the first sealing plate 111 is rotatably matched with the frame 1, and a second driving member 113 is provided on the frame 1. The second driving member 113 is a motor, which is used to drive the first sealing plate 111 to rotate, and the other end of the first sealing plate 111 stops against the conveyor belt 3. The second sealing plate 112 is located below the first sealing plate 111, and one end of the second sealing plate 112 is rotatably matched with the frame 1. A third driving member 114 is provided on the frame 1, and the third driving member 114 is a motor, which is used to drive the second sealing plate 112 to rotate, and the other end of the second sealing plate 112 stops against the conveyor belt 3, and a sealed compartment is formed between the first sealing plate 111 and the second sealing plate 112.

[0039] According to the device for air pollution control according to the embodiment of the present invention, air enters the upper chamber from the left air inlet 13, and is filtered by the filter plate 52 to filter out dust or other particulates in the air. During the filtering process, at least two filter components 5 are always maintained in the upper chamber to prevent the filter plate 52 in a filter component 5 from being damaged, resulting in reduced filtering effect.

[0040] In the initial state, the elastic force of the second elastic member 55 is greater than the elastic force of the first elastic member 54, so that the first elastic member 54 is in a contracted state. When the filter assembly 5 is about to move to the sealing assembly on the left, the first sealing plate 111 of the left sealing assembly rotates under the second driving member 113, thereby opening the sealed compartment, and the filter assembly 5 moves into the sealing assembly. Then the first sealing plate 111 is closed, and the second driving member 113 drives the second sealing plate 112 to open. The filter assembly 5 moves to the lower chamber, and the second filter plate 52 is closed. The filter assembly 5 moves from left to right in the lower chamber. At this time, the fourth elastic member 63 stretches to a natural state and pushes the driving rod 62 out of the sliding frame 53. The driving rod 62 drives the driving gear 61 to rotate during the movement, and the blades 56 rotate synchronously with the driving gear 61, so that the multiple blades 56 stop each other, thereby closing the shutter structure. When the limit block 531 abuts against the stop block 7, the stop block 7 blocks the limit block 531, so that the sliding frame 53 moves to the left relative to the filter frame 51, the second elastic member 55 contracts, and the first elastic member 54 stretches. When the first elastic member 54 stretches to a natural state, the sliding frame 53 drives the filter plate 52 to move to the left through the first elastic member 54. When the sliding frame 53 moves to the left and abuts against the filter frame 51, the limit block 531 squeezes the stop block 7, so that the third elastic member 8 contracts, and the stop block 7 is pressed into the frame body 1. The second elastic member 55 releases its elastic force and pushes the sliding frame 53 to move quickly to the right. The filter plate 52 and the sliding frame 53 moves to the right synchronously. When the filter plate 52 stops at the limit groove, the filter plate 52 vibrates due to the collision, and the particles attached to the filter plate 52 are shaken off by the vibration. At this time, the sliding frame 53 continues to move to the right, and the closed louver structure squeezes the air between the blades 56 and the filter plate 52. The airflow moves from the left end to the right end of the filter plate 52. The remaining particles attached to the filter plate 52 can be taken away by the airflow, and the particles scattered on the filter frame 51 can be blown away from the filter frame 51. The particles fall into the funnel-shaped structure at the bottom of the lower chamber under the action of gravity and are discharged from the frame 1 through the ash discharge port 12.
