Description

Technical Field

[0001] This invention belongs to the technical field of environmental protection dust removal equipment, specifically a dust removal device for air pollution control in composite decorative panel processing. Background Technology

[0002] During the processing of composite decorative panels, such as cutting, grooving, and sanding, dust containing wood chips, resin adhesives, and surface coating particles is generated. This dust, after being dispersed by the processing airflow, affects the air quality in the workshop and has an adverse impact on the breathing environment of the operators. In order to reduce dust emissions, water washing purification equipment is usually used on the processing site to treat the dust-laden airflow. After the dust-laden airflow enters the treatment chamber, it comes into contact with the sprayed water. The dust particles lose their ability to disperse under the washing action of the water flow and fall into the lower collection area with the water flow. The purified airflow is then discharged outward.

[0003] In actual processing, the amount of dust generated is not constant. The dust concentration in the intake area increases significantly when the tool first contacts the material, during high-speed cutting, or continuous grinding. During standby, light trimming, or intermittent processing, the dust level decreases. If the spray water volume remains constant, the water curtain's interception capacity is mismatched with the dust-laden airflow when dust concentration increases, allowing some dust to continue to be discharged with the airflow. Conversely, when dust concentration decreases, a continuously large spray water volume increases the consumption of circulating water and burdens subsequent wastewater treatment. Dust containing adhesives and coating particles entering the water body forms a sticky muddy mixture, with some harmful components continuously entering the water, polluting the bottom circulating water. Existing water washing structures mostly use a fixed spray volume and store the flushed sludge and circulating water together in the bottom water tank. They lack the ability to passively adjust according to the dust concentration and also lack a timely separation structure for the sludge that falls into the water. This results in solid sludge being soaked in the water for a long time, increasing the difficulty of circulating water purification. Some equipment adjusts the spray volume through optical sensors, electronically controlled valves and other components, but there is always water mist, dust and mud splashing in the treatment chamber. The sensing parts will be covered by dirt, and the electrical connection parts will also be affected by the humid environment, resulting in insufficient stability. After the sticky sludge is deposited on the water filtration components, it will also block the filter holes and adhere to the filter surface, reducing the water filtration efficiency and hindering the sludge discharge process. Summary of the Invention

[0004] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide an air pollution control and dust removal device for composite decorative panel processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust removal device for air pollution control in composite decorative panel processing includes an air inlet pipe, a treatment box, a water collection box, a sensing component, an adjustment component, a slag discharge component, and a purification component. The sensing component includes a first plate disposed in the air inlet pipe, and a rotating shaft is provided on the first plate. The adjustment assembly includes a pipe body disposed on the air inlet pipe, a first block body disposed inside the pipe body, and an eccentric drive component disposed on the rotating shaft body; The slag discharge assembly includes a rocker arm disposed on the rotating shaft, the rocker arm being fitted with a second rod, and the second rod being connected to a second plate. When the first plate rotates due to the impact of airflow, the eccentric drive pushes the first block, causing the water passage area of ​​the pipe to change, and the rocker arm pushes the second plate to flip.

[0006] Preferably, the first plate is inclined inside the air inlet pipe, the outer contour of the first plate is smaller than the inner contour of the air inlet pipe, an air passage gap is formed between the first plate and the inner wall of the air inlet pipe, the rotating shaft passes through the first plate, and the rotating shaft is rotatably connected to the air inlet pipe.

[0007] Preferably, the pipe body is provided with a first groove, the first groove intersects with the water supply channel inside the pipe body, the first block is slidably disposed in the first groove, and the length of the first block extending into the water supply channel changes when the first block moves.

[0008] Preferably, the adjustment assembly further includes a first rod, one end of which is connected to the first block, and the other end of which abuts against the eccentric drive member. When the eccentric drive member rotates, it pushes the first rod, causing the first rod to move the first block.

[0009] Preferably, the eccentric drive member is provided with a second block, which is offset from the axis of the rotating shaft. When the airflow impact on the first plate is weakened, the second block drives the eccentric drive member to reset.

[0010] Preferably, the rocker arm is provided with a second groove, and the second rod is provided with a third rod. The third rod is slidably disposed in the second groove. When the rocker arm swings, it pushes the third rod through the second groove, causing the second rod to move.

[0011] Preferably, the second plate is rotatably disposed inside the processing box, the second plate is provided with water filter holes, the processing box is provided with a third tank, and when the second rod moves, it drives the second plate to flip toward the third tank.

[0012] Preferably, the third tank penetrates the side wall of the treatment box, and the treatment box is connected to an outlet structure communicating with the third tank. After the second plate flips towards the third tank, the sludge on the second plate enters the outlet structure through the third tank.

[0013] Preferably, the purification component includes a fourth rod disposed in the treatment box, the fourth rod being provided with a draining component, the draining component being disposed corresponding to the water filter hole, and the draining component entering the water filter hole when the second plate is flipped.

[0014] Preferably, the purification component further includes a third block disposed within the treatment box, the third block being located at the flipping path of the second plate, the second plate abutting against the third block after flipping, and the water collection tank being disposed on the drainage side of the treatment box, the water collection tank being used to collect water flowing out through the filter holes.

[0015] The beneficial effects of this invention are as follows: I. In this invention, the mechanical triggering caused by the impact of the dust-laden airflow itself allows the spray water supply to change with the intensity of the dust impact. When the dust concentration increases, the force-bearing parts in the air inlet path rotate significantly, increasing the water flow area of ​​the water supply channel. This matches the spray water volume with the current dust-laden airflow, thereby improving the interception effect on high-concentration dust. When the dust concentration decreases, the water supply channel returns to its initial state, reducing the amount of spray water used under low-dust conditions. This adjustment process does not rely on optical detection and electronically controlled valves, reducing the impact of water mist, dust adhesion, and mud splashing on the adjustment stability. After the sprayed sludge enters the treatment tank with the water, the filtration section can be flipped and discharged under the same mechanical action, separating the sludge from the filtered water. This reduces the residence time of sludge containing adhesives and coating particles in the water, thereby reducing the degree of continuous pollution of the circulating water. Second, in this invention, the filter holes are unblocked and the sludge is removed by vibration during the flipping process of the water filtration section. This can push out the sticky sludge adhering to the filter holes and loosen the sludge on the receiving surface before it is discharged through the sludge discharge channel. This structure allows the water filtration, sludge discharge, blockage removal and sludge removal actions to be completed in conjunction with the airflow triggering process, reducing the frequency of manual cleaning of the water filtration section and helping to keep the water filtration channel unobstructed. The filtered water can be further processed after entering the water collection tank, which is convenient for subsequent recycling and wastewater treatment. Attached Figure Description

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Please see Figure 1 A dust removal device for air pollution control in composite decorative panel processing includes an air inlet pipe 1, a treatment box 2, a water collection box 3, a sensing component 4, an adjustment component 5, a slag discharge component 6, and a purification component 7.

[0020] It should be noted that, in combination Figure 1 The air inlet pipe 1 is used to supply dust-laden airflow, the treatment box 2 is used to receive the sludge formed after the spray water and dust come into contact, the water collection box 3 is used to receive the water after filtration, the air inlet pipe 1 is set on the top of the treatment box 2, the treatment box 2 is set on the top of the water collection box 3, the sensing component 4 is set inside the air inlet pipe 1, the regulating component 5 is set on the water supply side of the air inlet pipe 1, the slag discharge component 6 is connected between the sensing component 4 and the treatment box 2, and the purification component 7 is set inside the treatment box 2.

[0021] like Figure 1 and Figure 2As shown, the air inlet pipe 1 is preferably made of stainless steel plate. The air inlet pipe 1 is a vertically arranged hollow tubular structure with an inlet end and an outlet end. The inlet end of the air inlet pipe 1 is used to receive the dust-laden airflow generated during the processing of the composite decorative panel. The outlet end of the air inlet pipe 1 faces the opening of the treatment box 2 and is connected to the treatment box 2. The dust-laden airflow can enter through the inlet end of the air inlet pipe 1 and enter the treatment box 2 through the outlet end of the air inlet pipe 1. The treatment box 2 is preferably made of stainless steel plate and is a box structure. The opening of the treatment box 2 faces the outlet end of the air inlet pipe 1. The treatment box 2 is used to receive the sprayed water and sludge entering through the air inlet pipe 1. A drainage area is provided near the water collection tank 3 in the treatment box 2, and the drainage area of ​​the treatment box 2 is connected to the water collection tank 3. Figure 8 and Figure 9 As shown, a third trough 64 is provided on the sludge discharge sidewall of the treatment tank 2. The third trough 64 is a long strip-shaped opening that penetrates the sidewall of the treatment tank 2. The third trough 64 is located near the drainage area of ​​the treatment tank 2. The third trough 64 is used to allow sludge to leave the treatment tank 2. An outlet structure is connected to the outside of the third trough 64. The outlet structure is preferably made of stainless steel plate. The outlet structure is an inclined trough-shaped structure. The inlet end of the outlet structure is connected to the third trough 64. The outlet structure is fixedly connected to the treatment tank 2. The outlet end of the outlet structure extends away from the treatment tank 2 and is inclined towards the collection container. After the sludge enters the outlet structure through the third trough 64, it can leave the treatment tank 2 along the outlet structure.

[0022] like Figure 1 and Figure 2 As shown, the water collection tank 3 is preferably made of stainless steel plate. The water collection tank 3 is a box structure and is located on the drainage side of the treatment tank 2. The opening of the water collection tank 3 faces the drainage area of ​​the treatment tank 2. The water collection tank 3 is used to receive the water discharged from the treatment tank 2. The water collection tank 3 is equipped with an activated carbon layer, which is used to adsorb the water entering the water collection tank 3. The water collection tank 3 can be connected to the circulating water pipeline, which can transport the water in the water collection tank 3 to the regulating component 5.

[0023] like Figure 3As shown, the sensing component 4 includes a first plate 41 and a rotating shaft 42. The first plate 41 is preferably made of stainless steel and has a rectangular plate structure. The first plate 41 is disposed inside the air inlet pipe 1, and the outer contour of the first plate 41 is smaller than the inner contour of the air inlet pipe 1. An air passage gap is formed between the first plate 41 and the inner wall of the air inlet pipe 1, which is used to allow the dust-laden airflow to pass through. The first plate 41 is inclined relative to the air outlet direction of the air inlet pipe 1. When the dust-laden airflow flows from the air inlet end to the air outlet end of the air inlet pipe 1, the dust-laden airflow can... The rotating shaft 42 is preferably made of stainless steel round rod and is inserted through the first plate 41. The rotating shaft 42 is fixedly connected to the first plate 41 and is offset from the center of the first plate 41. The two ends of the rotating shaft 42 pass through the opposite side walls of the air inlet pipe 1. The rotating shaft 42 is rotatably connected to the air inlet pipe 1. After the first plate 41 is impacted by the dust-laden airflow, the first plate 41 can deflect around the rotating shaft 42. When the first plate 41 deflects, the first plate 41 drives the rotating shaft 42 to rotate synchronously.

[0024] When using, combine with the attached Figure 3 As shown, after the dust-laden airflow enters the air inlet pipe 1, it will first contact the first plate 41. Due to its inclined setting, the first plate 41 can withstand the impact force of the dust-laden airflow. When the impact force of the dust-laden airflow increases, the deflection of the first plate 41 will increase accordingly. The first plate 41 is fixed on the rotating shaft 42, so the deflection of the first plate 41 can be directly transmitted to the rotating shaft 42. After the rotating shaft 42 rotates, it can simultaneously drive the adjustment component 5 and the slag discharge component 6 to move.

[0025] like Figures 4 to 6 As shown, the regulating component 5 includes a pipe body 51, preferably made of stainless steel. The pipe body 51 is located on the water supply side of the air inlet pipe 1 and is fixedly connected to the air inlet pipe 1. One end of the pipe body 51 is used to connect to the water supply pipeline, and the other end of the pipe body 51 extends into the air inlet pipe 1. An atomizing nozzle is provided at the end of the pipe body 51 extending into the air inlet pipe 1. A water supply channel is formed inside the pipe body 51, allowing spray water to enter the air inlet pipe 1 along the water supply channel. The first groove 511 is provided on the top. The first groove 511 is a groove-shaped structure that cooperates with the first block 52. The first groove 511 intersects with the water supply channel inside the pipe 51. The first groove 511 is used to accommodate the first block 52. The first block 52 is preferably made of wear-resistant plastic block. The first block 52 is slidably disposed in the first groove 511. The first block 52 is in contact with the groove wall of the first groove 511. The first block 52 can move along the first groove 511.

[0026] It should be noted that, in combination Figure 5 and Figure 6A portion of the first block 52 can extend into the water supply channel inside the pipe 51. When the length of the first block 52 extending into the water supply channel increases, the space for water to pass through the water supply channel decreases, and the amount of spray water entering the air inlet pipe 1 decreases. When the length of the first block 52 extending into the water supply channel decreases, the space for water to pass through the water supply channel increases, and the amount of spray water entering the air inlet pipe 1 increases. The first groove 511 plays a guiding role for the first block 52 and can limit the first block 52 from deviating from the predetermined movement direction.

[0027] like Figures 4 to 6 As shown, the first rod 53 is preferably made of stainless steel round rod. The first rod 53 is set vertically, one end of the first rod 53 is fixedly connected to the first block 52, and the other end of the first rod 53 abuts against the outer peripheral surface of the eccentric drive member 54. The first rod 53 can move along its own length direction. When the first rod 53 moves, it can drive the first block 52 to move within the first groove 511. After the first block 52 moves, the space through which water is supplied in the water supply channel inside the pipe 51 changes. The eccentric drive member 54 is preferably made of stainless steel and has an eccentric wheel-like structure. The eccentric drive member 54 is fixedly connected to the end of the rotating shaft 42 that extends out of the air inlet pipe 1. The eccentric drive member 54 can rotate synchronously with the rotating shaft 42. The outer peripheral surface of the eccentric drive member 54 abuts against the first rod 53. The distance from the outer peripheral surface of the eccentric drive member 54 to the axis of the rotating shaft 42 is not equal. When the drive member 54 rotates, different positions on the outer circumference of the eccentric drive member 54 abut against the first rod 53 in sequence, causing the first rod 53 to move along its own length. The first rod 53 drives the first block 52 to move, and the first block 52 changes the space through which water flows in the water supply channel inside the pipe 51. The second block 55 is preferably made of cast iron and is fixed to one side of the bottom of the eccentric drive member 54 in its initial state. The second block 55 is used to generate a reset torque. When the first plate 41 is impacted by the dust-laden airflow, the first plate 41 drives the rotating shaft 42 to rotate, the rotating shaft 42 drives the eccentric drive member 54 to rotate, and the eccentric drive member 54 drives the second block 55 to deflect. After the impact of the dust-laden airflow on the first plate 41 weakens, the second block 55 drives the eccentric drive member 54 to rotate in the opposite direction under its own weight. After the eccentric drive member 54 rotates in the opposite direction, the rotating shaft 42 and the first plate 41 are reset.

[0028] When using, combine Figures 4 to 6As shown, the rotating shaft 42 rotates and drives the eccentric drive 54 to rotate. The outer circumferential surface of the eccentric drive 54 pushes the first rod 53. The first rod 53 drives the first block 52 to move along the first groove 511. The first block 52 changes its length extending into the water supply channel of the pipe 51. The space through which the water supply passes in the pipe 51 changes accordingly. When the impact of the dust-laden airflow on the first plate 41 increases, the rotation of the rotating shaft 42 increases. The pushing amount of the eccentric drive 54 on the first rod 53 increases. The first block 52 increases the space through which the water supply passes in the pipe 51. The amount of spray water input into the air inlet pipe 1 from the pipe 51 increases. After the spray water comes into contact with the dust-laden airflow, the dust enters the treatment box 2 with the water.

[0029] like Figures 7 to 10 As shown, the slag discharge assembly 6 includes a rocker arm 61, which is preferably made of stainless steel plate. The rocker arm 61 is a long strip plate structure. One end of the rocker arm 61 is fixedly connected to the other end of the rotating shaft 42 extending out of the air inlet pipe 1. The rocker arm 61 can swing synchronously with the rotating shaft 42. A second groove 611 is provided on the rocker arm 61. The second groove 611 is a long strip groove extending along the length direction of the rocker arm 61. The second groove 611 is used to connect with the third groove on the second rod 62. The rod body 621 is fitted together, and the second rod body 62 is preferably made of stainless steel round rod. The second rod body 62 is vertically arranged on one side of the air inlet pipe 1. A third rod body 621 is provided at one end of the second rod body 62. The third rod body 621 is preferably made of stainless steel short shaft. The third rod body 621 is arranged horizontally and passes through the second groove 611. The third rod body 621 can slide in the second groove 611, and the groove wall of the second groove 611 can apply a thrust to the third rod body 621.

[0030] When using, combine Figure 7 As shown, the rotating shaft 42 rotates and drives the rocker arm 61 to swing. When the rocker arm 61 swings, the position of the second groove 611 changes with the rocker arm 61. The third rod 621 is restricted in the second groove 611. The groove wall of the second groove 611 pushes the third rod 621 to move. The third rod 621 slides in the second groove 611, and at the same time drives the second rod 62 to move vertically. Thus, the swing of the rocker arm 61 is converted into the lifting and lowering movement of the second rod 62.

[0031] like Figures 7 to 10As shown, the second plate 63 is preferably made of stainless steel mesh. The second plate 63 has a rectangular plate structure and is set inside the treatment tank 2. The second plate 63 is located between the opening of the treatment tank 2 and the water collection tank 3. The second plate 63 has multiple water filter holes 631 that penetrate the second plate 63. One edge of the second plate 63 is hinged to the inner wall of the treatment tank 2, and the other edge of the second plate 63 is connected to the second rod 62. When the second rod 62 moves in the direction close to the water collection tank 3, the second rod 62 pulls the second plate 63 to rotate around its hinge point. When the second rod 62 moves in the direction away from the water collection tank 3, the second rod 62 drives the second plate 63 back to a near-horizontal state.

[0032] It should be noted that, in combination Figures 8 to 10 When the second plate 63 is in its initial state, it is nearly horizontal. After the sprayed water and dust fall onto the second plate 63, the water can flow into the water collection tank 3 through the filter holes 631. The sludge is trapped on the receiving surface of the second plate 63. After the second plate 63 is flipped under the pull of the second rod 62, the second plate 63 tilts towards the third tank 64. The sludge on the second plate 63 can move along the surface of the second plate 63 and enter the discharge structure through the third tank 64. This structure can reduce the sludge from soaking in the treatment tank 2 for a long time.

[0033] like Figures 8 to 10 As shown, the purification component 7 includes a fourth rod 71 and a third block 72. The fourth rod 71 is preferably made of stainless steel. The fourth rod 71 is disposed inside the treatment box 2 and is located between the second plate 63 and the water collection tank 3. Both ends of the fourth rod 71 are fixedly connected to the inner wall of the treatment box 2. The fourth rod 71 is provided with a plurality of unblocking parts 711. The unblocking parts 711 are preferably made of thin stainless steel rods. The plurality of unblocking parts 711 are spaced apart along the length direction of the fourth rod 71. Each unblocking part 711 is an arc-shaped rod structure. One end of the unblocking part 711 is fixed to the fourth rod 71, and the other end of the unblocking part 711 faces the second plate 63.

[0034] It should be noted that, in combination Figure 9 and Figure 10The unblocking component 711 is not a vertical rod, but rather bends along the arc path traversed by the filter hole 631 when the second plate 63 is flipped. The outer diameter of the unblocking component 711 is smaller than the diameter of the filter hole 631. Each unblocking component 711 corresponds to one filter hole 631. When the second plate 63 is in a nearly horizontal initial state, the end of the unblocking component 711 is located on the side of the filter hole 631 closest to the water collection tank 3. The unblocking component 711 does not penetrate the filter hole 631. After the second plate 63 begins to rotate, the filter hole 631 gradually approaches the unblocking component 711. The filter hole 631 is inserted into the unblocking component 711 along the bending direction of the unblocking component 711. After the unblocking component 711 enters the filter hole 631, it pushes out the adhering sludge inside the filter hole 631. When the second plate 63 continues to rotate, the unblocking component 711 moves relative to the hole wall of the filter hole 631, and the sludge inside the filter hole 631 can be separated from the second plate 63.

[0035] like Figures 8 to 10 As shown, the third block 72 is preferably made of stainless steel. The third block 72 is fixed on the inner wall of the treatment box 2. The third block 72 is located at the flipping path of the second plate 63. The receiving surface of the third block 72 faces the second plate 63. After the second plate 63 flips to a position close to the third tank 64, the slag discharge edge of the second plate 63 can hit the third block 72. The third block 72 limits the second plate 63. After the second plate 63 is hit, the sludge adhering on the receiving surface of the second plate 63 can be loosened. The loosened sludge can enter the third tank 64 along the second plate 63. The sludge enters the discharge structure through the third tank 64. The discharge structure discharges the sludge from the treatment box 2.

[0036] The working principle of this embodiment is as follows: Induction phase, combined Figures 1 to 3 The dust-laden airflow enters through the inlet end of the air inlet pipe 1 and flows towards the outlet end of the air inlet pipe 1. The dust-laden airflow impacts the first plate 41, causing the first plate 41 to deflect. The first plate 41 drives the rotating shaft 42 to rotate, and the rotating shaft 42 transmits power to the regulating component 5 and the slag discharge component 6. When the dust concentration increases, the impact force of the dust-laden airflow on the first plate 41 increases, the deflection of the first plate 41 increases, and the rotation of the rotating shaft 42 increases accordingly. During the spray adjustment phase, combined with Figures 3 to 6 The rotating shaft 42 drives the eccentric drive 54 to rotate. The outer circumferential surface of the eccentric drive 54 pushes the first rod 53. The first rod 53 drives the first block 52 to move in the first tank 511. The first block 52 changes its length extending into the water supply channel of the pipe 51. The space through which the water supply passes in the pipe 51 changes accordingly. When the dust concentration increases, the first block 52 increases the space through which the water supply passes in the pipe 51. The amount of spray water input from the pipe 51 into the air inlet pipe 1 increases. After the spray water comes into contact with the dust-laden airflow, the dust enters the treatment box 2 with the water. During the water filtration and sludge removal stage, combined with Figures 7 to 10 The rotating shaft 42 drives the rocker arm 61 to swing. The rocker arm 61 pushes the third rod 621 through the second groove 611. The third rod 621 drives the second rod 62 to move in the direction close to the water collection tank 3. The second rod 62 pulls the second plate 63 to flip. The second plate 63 changes from a near-horizontal water filtering state to a sludge discharge state tilted towards the third groove 64. The spray water enters the water collection tank 3 through the water filtering hole 631. The sludge is intercepted by the second plate 63. After the second plate 63 tilts, the sludge enters the third groove 64 along the second plate 63. The sludge enters the discharge structure through the third groove 64. The discharge structure discharges the sludge out of the treatment box 2. During the congestion clearing phase, combined with Figures 7 to 10 During the flipping process of the second plate 63, the filter holes 631 on the second plate 63 gradually approach the unblocking component 711. The unblocking component 711 enters the filter holes 631 along the moving path of the filter holes 631 and pushes out the adhering sludge in the filter holes 631. When the second plate 63 continues to flip, the unblocking component 711 moves relative to the hole wall of the filter holes 631, and the sludge in the filter holes 631 is carried away from the filter holes 631. After the second plate 63 flips to a position close to the third tank 64, the second plate 63 impacts the third block 72. The third block 72 limits the second plate 63. The adhering sludge on the receiving surface of the second plate 63 is loosened after the impact, and the loosened sludge slides along the second plate 63 to the third tank 64. Water collection and purification stage, combined with Figure 1 and Figure 8 Water passing through the filter holes 631 enters the water collection tank 3. The activated carbon layer in the water collection tank 3 adsorbs pollutants in the water. After adsorption treatment, the water can re-enter the pipe body 51 through the circulating water pipe, thereby reducing the time that sludge and water mix and stay in the treatment tank 2. During the reset phase, combined with Figures 5 to 9 After the impact of the dust-laden airflow on the first plate 41 is weakened, the second block 55 drives the eccentric drive 54 to rotate in the opposite direction under its own weight. The eccentric drive 54 drives the rotating shaft 42 to rotate in the opposite direction. The rotating shaft 42 drives the first plate 41 back to the initial tilt position. The rotating shaft 42 drives the rocker arm 61 to swing in the opposite direction. The rocker arm 61 drives the third rod 621 to reset through the second groove 611. The third rod 621 drives the second rod 62 to reset in the direction away from the water collection tank 3. The second rod 62 drives the second plate 63 to return to a near-horizontal water filtration state. When the eccentric drive 54 rotates in the opposite direction, the pushing amount of the eccentric drive 54 on the first rod 53 decreases. The first rod 53 and the first block 52 return to the initial position with the eccentric drive 54. The pipe 51 returns to the initial water supply state. The device completes one induction adjustment, spray dust collection, water filtration and slag discharge, blockage clearing and reset process. In summary, the first plate 41 is used to convert the impact of the dust-laden airflow into the rotation of the rotating shaft 42. The rotating shaft 42 serves as the common transmission base. One end of the rotating shaft 42 adjusts the water supply of the pipe 51 through the eccentric drive 54, the first rod 53, and the first block 52. The other end of the rotating shaft 42 drives the second plate 63 to rotate through the rocker arm 61, the third rod 621, and the second rod 62. The second plate 63 is used for filtering water and receiving sludge. The unblocking component 711 is used to clean the filter holes 631. The third block 72 is used to limit and vibrate the second plate 63. The third tank 64 and the discharge structure are used to discharge sludge from the treatment tank 2. The water collection tank 3 is used to receive and purify the filtered water.
