Description

Technical Field

[0001] The invention belongs to the technical field of dust treatment, and relates to a dust treatment device, in particular to a cutting dust treatment device for foam lost foam production. Background Art

[0002] With the development of modern manufacturing industry, lost foam production has become a common production process. Lost foam production is a manufacturing method that uses foam materials such as polystyrene to make models. After a certain period of time, the foam material disappears to form a cavity, and then metal or other materials are injected into the cavity to finally obtain the desired product.

[0003] However, a lot of dust and waste will be generated during the production process of lost foam, which will cause serious environmental pollution if not handled in time. The traditional treatment method is to clean and handle it manually, but this method is inefficient and has safety hazards.

[0004] After searching, it is found that a cutting dust treatment device for foam lost foam production is disclosed in Chinese patent documents [Application number: 202323406155.9; Publication number: CN 221310045 U]. This dust treatment device includes a filter box, one side of the filter box is fixedly provided with an air inlet pipe at the lower end, and both sides of the inner wall of the filter box are provided with slide grooves, a filter frame is slidably provided in the middle of the filter box, and a plurality of first filter screens are fixedly provided inside the filter frame, a dust removal box is fixedly provided on the side of the filter box away from the air inlet pipe, a partition is fixedly provided in the middle of the dust removal box, a fixed pipe is fixedly provided inside the dust removal box at the upper end, and a plurality of nozzles are fixedly provided at the lower end of the fixed pipe, a shell is fixedly provided on one side of the upper end of the dust removal box, and an air pump is fixedly provided inside the shell, and an air intake pipe is fixedly connected to the input end of the air pump. In this application, the device can process the dust in the foam lost foam cutting multiple times to improve the dust treatment effect.

[0005] Although the dust device disclosed in the patent can process the dust in the foam lost foam cutting multiple times and improve the dust treatment effect, the dust treatment device needs to be shut down and the filter screen needs to be cleaned after being used for a period of time, which is not only troublesome but also affects the dust collection efficiency. At the same time, the leached sewage is recycled but the sewage is not treated. After working for a period of time, the leaching effect deteriorates, affecting the dust treatment quality. Summary of the invention

[0006] The purpose of the present invention is to address the above-mentioned problems in the existing technology and to propose a cutting dust treatment device for foam lost foam production. The technical problem to be solved by the invention is: how to ensure work efficiency while improving the quality of dust treatment.

[0007] The purpose of the present invention can be achieved by the following technical solutions: A cutting dust treatment device for foam lost foam production comprises a filter box and a leaching box, wherein an air inlet end of the filter box is provided with a dust suction hood, an air outlet end of the filter box is connected with the leaching box, a waste box is fixed at the front and rear sides of the filter box, a filter frame is fixed inside the filter box, three filter screens are fixed inside the filter frame, and the meshes of the three filter screens decrease successively from bottom to top, a first motor is fixed in the filter frame, a first threaded rod is fixed at the output shaft end of the first motor, a cleaning brush is threadedly connected on the first threaded rod, the cleaning brush and the filter screen correspond one to one, triangular scrapers are fixed at the bottom of the front and rear sides of the cleaning brush, a plurality of inclined feeding ports are opened between the filter box and the waste box, and the feeding ports correspond one to one with the filter screen, a first elastic component is fixed inside the waste box, a sealing plate is fixed on the first elastic component, the sealing plate is fitted with the feeding port, ejector rods are fixed on both sides of the lowest cleaning brush, and ejection holes matching the ejector rods are opened between the filter box and the waste box.

[0008] The working principle of the present invention is as follows: during operation, the dust generated by the cutting of the foam lost foam production is sucked into the filter box by using the dust suction hood, and the filter screen inside the filter box is used for multi-stage filtration, and then the filtered air is sent to the leaching box, and the air is sprayed and filtered by spraying, and then the air is discharged, thereby realizing multi-stage filtration and purification of dust. While filtering, the first motor is turned on, and the reciprocating forward and reverse rotation of the first motor drives the cleaning brush to move forward and backward, so as to scrape off the impurities such as foam attached to the bottom of the filter screen, and send it into the waste box through the discharge port, so as to prevent The filter will be clogged, affecting the filtering effect and efficiency. The setting of the triangular scraper makes the triangular scraper fit the filter below it. During the movement, it can scrape off and press down some of the foam stuck in the mesh of the filter. The cleaning brush below can further improve the cleaning effect of the filter. The setting of the blocking plate blocks the discharge port during normal operation to prevent wind from bypassing the filter through the discharge port. During cleaning, when the cleaning brush approaches the discharge port, the ejector pushes open the blocking plate through the ejection hole to achieve the debris removal operation.

[0009] The left and right sides of the cleaning brush are both provided with grooves located below the first threaded rod, a second elastic component is fixed inside the groove, a top plate is fixed on the upper end of the second elastic component, a plurality of cleaning steel needles are fixed on the top plate, and the cleaning steel needles correspond to the thread grooves of the first threaded rod.

[0010] With the above structure, during operation, the threaded rod rotates to drive the cleaning brush to move, and at the same time the cleaning steel needle will extend into the thread groove to clean the thread groove. After the thread groove is cleaned, the thread groove is meshed with the cleaning brush to prevent dust and other debris from affecting the meshing of the threaded rod and the cleaning brush, thereby extending the service life of the threaded rod and ensuring normal operation.

[0011] A spray plate is fixed inside the leaching box, a partition is fixed at the lower end of the inside of the leaching box, the partition divides the lower half of the leaching box into two water chambers, an overflow port is provided on the upper part of the partition, a water supply pipe is fixed on the leaching box, a sewage pipe is fixed at the lower end of the water chamber, a water pump is fixed outside the leaching box, a water suction pipe is fixed to the water inlet end of the water pump, the water suction pipe extends into the water chamber, the water outlet end of the water pump is connected with the spray plate, a plurality of water suction ports are provided on the pipe sections of the water suction pipe located in the two water chambers, a first closing component is provided on the upper part of the water chamber, a second closing component is provided on the lower part of the water chamber, and a plugging component cooperating with the water suction port is provided on the first closing component.

[0012] With the above structure, when working, the water in the water cavity is extracted by the water pump, sprayed from the spray plate, and sent to the filter box into the air for leaching operation. When working, the water extraction port in one of the water cavities is blocked by the blocking component, and the water extraction port in the other water cavity is opened, so that the water pump will only extract water from one of the water cavities, and the other water cavity, when the blocking component blocks the water extraction port, uses the first sealing component to seal the upper end of the water cavity, so that the water in the water cavity can stand still. After standing still for a period of time, the second sealing component seals the lower part of the water cavity, so that the standing water in the water cavity is not enough. The generated sediment is located below the second closed component, and then the sewage pipe is opened for sewage discharge. After the sewage discharge is completed, the sewage pipe is closed, and then the first closed component, the second closed component and the plugging component of the water chamber are opened. At the same time, the first closed component and the plugging component in the other water chamber are opened, and the water suction port in the water chamber and the upper end of the water chamber are closed. The above sewage discharge operation is repeated. In this cycle, the two water chambers can be switched for sewage discharge while leaching to ensure the cleanliness of the water quality. While ensuring the leaching effect, there is no need to stop the machine for cleaning, thereby improving work efficiency.

[0013] The first closing component includes a first U-shaped plate fixed on the front and rear sides of the water cavity, the first U-shaped plate is slidably connected to the inside of the first closing plate, the first U-shaped plate and the left and right sides of the first closing plate are in contact with the side walls of the water cavity, the first U-shaped plate is rotatably connected to the inside of the second threaded rod, the second threaded rod is threadedly connected to the first closing plate, the other end of the second threaded rod extends out of the first U-shaped plate, a second motor is fixed to the leaching box, the output shaft of the second motor is threadedly connected to the second threaded rod in one of the water cavities, a sprocket is fixed to the second threaded rod, the sprockets between the two water cavities are connected by a chain, and the threads of the second threaded rods in the two water cavities are in opposite directions.

[0014] With the above structure, during operation, the second motor drives the second threaded rods in the two water chambers to rotate simultaneously. Since the threads of the second threaded rods in the two water chambers have opposite rotation directions, when the second threaded rods rotate, the first closing plate in one of the water chambers extends out of the first U-shaped plate, and the first closing plate in the other water chamber enters the first U-shaped plate, thereby achieving the goal of closing one water chamber while opening the other water chamber. The structure is simple and convenient, and prevents the water sprayed from the spray plate from affecting the stationary state when the shower is at rest.

[0015] The plugging assembly comprises a connecting rod, the upper end of which is fixedly connected to the first closing plate, the lower end of which is fixed with a semi-annular closing cover, and the inner side of which is fixed with a sealing gasket.

[0016] With the above structure, when the two first closing plates move toward each other, the two semi-annular closing covers will be driven to move toward each other through the connecting rod, so that while the first closing plate closes the water cavity, the two semi-annular closing covers close the water extraction holes in the water cavity. The structure is simple, does not require additional drive, reduces the cost of the equipment, ensures the coordinated performance of the work, and reduces the occurrence of failure rates.

[0017] The second closing component includes a second U-shaped plate fixed on the front and rear sides of the water chamber, the first closing plate is slidably connected inside the second U-shaped plate, the second U-shaped plate and the left and right sides of the second closing plate are in contact with the side wall of the water chamber, a third motor is fixed inside the first U-shaped plate, the output shaft end of the third motor is fixedly connected to a third threaded rod, and the third threaded rod is threadedly connected to the second closing plate.

[0018] With the above structure, when it is necessary to close the lower part of the water chamber after standing still, the third motor drives the third threaded rod to rotate, so that the front and rear second closing plates move toward each other until the ends of the two closing plates collide, and then the sewage pipe is opened to carry out sewage discharge. After the sewage discharge is completed, the third motor reverses, so that the two second closing plates move in the opposite direction, thereby opening the lower part of the water chamber to facilitate the next work.

[0019] An annular air inlet seat is fixed inside the leaching box, which is connected to the air outlet end of the filter box. A plurality of air jet pipes are fixed at the lower end of the annular air inlet seat. The upper half of the air jet pipes is arranged vertically downward, the lower half of the air jet pipes is arranged inclined, and the air outlet end of the air jet pipes is inclined toward the center of the leaching box.

[0020] With the above structure, after the air in the filter box enters the annular air inlet seat, it is sprayed downward at an angle through the air spray pipe, which not only allows the sprayed air to move downward for a certain distance under the action of inertia, thereby prolonging the contact time between air and water, but also allows the air to be sprayed obliquely toward the center, causing the air flow to collide, thereby accelerating the diffusion of the air, reducing the flow rate, and further improving the quality of leaching.

[0021] An air inlet pipe is fixed to the air inlet end of the filter box, a temporary storage box is fixed to the other end of the air inlet pipe, a control valve is fixed on the air inlet pipe, a driving gear is fixed on the valve stem of the control valve, a suction fan is fixed to the air inlet end of the temporary storage box, a dust hood is fixed to the suction fan through a hose, a spring is fixed to the inside of the temporary storage box, a piston plate is fixed to the other end of the spring, a sliding rod is fixed to the upper side of the piston plate, the upper end of the sliding rod extends out of the temporary storage box and is fixed with a driving rod, a lifting rod is slidably connected to the outside of the temporary storage box, two driven rods are fixed on the lifting rod, the driving rod is located between the two driven rods, a tooth plate is fixed to the lower end of the lifting plate, and the tooth plate is meshed with the driving gear.

[0022] When the air is sucked out of the filter, the filter presses on the filter housing, and the filter presses on the filter housing to open the control valve, so that the air in the filter housing is exhausted and the filter presses on the filter housing, and the filter presses on the filter housing to open the control valve.

[0023] A drying box is fixed on the upper end of the leaching box, a filter box is fixed inside the drying box, a plurality of annularly distributed filter cavities are opened in the filter box, a fourth motor is fixed on the upper end of the drying box, a rotating shaft is fixed on the output shaft end of the fourth motor, two circular plates are fixed on the rotating shaft, the two circular plates are respectively located on the upper and lower sides of the filter box, a plurality of sealing covers are fixed on the outer periphery of the circular plates, a hot air blower is fixed on the lower sealing cover, a ventilation pipe is fixed on the upper sealing cover, an exhaust pipe is fixed on the drying box, an annular exhaust cover is fixed on the lower end of the exhaust pipe, an annular sealing plate is slidably connected to the lower side of the annular exhaust cover, and the ventilation pipe is slidably connected to the annular sealing plate.

[0024] With the above structure, during operation, the sealing covers arranged on the upper and lower sides of the filter box can be used to seal half of the filter cavity, while the other half of the filter cavity is normally dried. After a period of use, the fourth motor drives the circular plate to rotate, so that the position of the sealing cover is switched, so that the sealing cover seals the filter cavity that has been used for a period of time, and opens the other half of the filter cavity. At the same time, the hot air blower is turned on to dry the dry particles in the filter cavity after use, so that the dry particles can be reused, extending the service life of the dry particles. At the same time, there is no need to stop the machine for replacement, thereby ensuring work efficiency.

[0025] Compared with the prior art, the cutting dust treatment device for foam lost foam production has the following advantages: 1. During operation, the dust generated by the cutting of the foam lost foam production is sucked into the filter box by using the dust hood, and the filter screen inside the filter box is used for multi-stage filtration. Then, the filtered air is sent to the leaching box, and the air is sprayed and filtered by spraying, and then the air is discharged, realizing multi-stage filtration and purification of dust. While filtering, the first motor is turned on, and the reciprocating forward and reverse rotation of the first motor drives the cleaning brush to move forward and backward, scraping off the foam and other impurities attached to the bottom of the filter screen, and sending it into the waste box through the discharge port to prevent the filter screen from being damaged. It causes blockage and affects the filtering effect and efficiency. The setting of the triangular scraper makes the triangular scraper fit with the filter below it. During the movement, it can scrape off and press down some of the foam stuck in the mesh of the filter. The cleaning brush below can further improve the cleaning effect of the filter. The setting of the blocking plate blocks the discharge port during normal operation to prevent wind from bypassing the filter through the discharge port. During cleaning, when the cleaning brush approaches the discharge port, the ejector pushes open the blocking plate through the ejection hole to realize the debris removal operation.

[0026] 2. During operation, the threaded rod rotates to drive the cleaning brush to move, and at the same time, the cleaning steel needle will extend into the thread groove to clean the thread groove. After the thread groove is cleaned, the thread groove and the cleaning brush will be engaged to prevent dust and other debris from affecting the engagement of the threaded rod and the cleaning brush, thereby extending the service life of the threaded rod and ensuring the normal operation of the work.

[0027] 3. When working, the water in the water cavity is extracted by the water pump, sprayed from the spray plate, and sent to the filter box into the air for leaching operation. When working, the water extraction port in one of the water cavities is blocked by the blocking component, and the water extraction port in the other water cavity is opened, so that the water pump will only extract water from one of the water cavities, and the other water cavity, while the blocking component blocks the water extraction port, uses the first sealing component to seal the upper end of the water cavity, so that the water in the water cavity can stand still. After standing still for a period of time, the second sealing component seals the lower part of the water cavity, so that the standing still produces The sediment is located below the second closed component, and then the sewage pipe is opened to carry out sewage discharge. After the sewage discharge is completed, the sewage pipe is closed, and then the first closed component, the second closed component and the plugging component of the water chamber are opened. At the same time, the first closed component and the plugging component in the other water chamber are opened, and the water suction port in the water chamber and the upper end of the water chamber are closed. The above sewage discharge operation is repeated. In this cycle, the two water chambers can be switched to discharge sewage while leaching to ensure the cleanliness of the water quality. While ensuring the leaching effect, there is no need to stop the machine for cleaning, thereby improving work efficiency.

[0028] 4. After the air in the filter box enters the annular air inlet seat, it is sprayed downward through the air nozzle. Not only can the sprayed air move downward for a certain distance under the action of inertia, thereby prolonging the contact time between air and water, but also the setting that the air is sprayed toward the center can cause air flow collision, accelerate air diffusion, reduce flow rate, and further improve the quality of leaching.

[0029] 5. The control valve is closed at the beginning. When vacuuming, air enters the temporary storage box and squeezes the piston plate, causing the piston plate to move up, thereby driving the driving rod to move up through the sliding rod. When the driving rod moves up to a certain height, the driving rod contacts the driven rod above, thereby driving the lifting rod to rise through the driven rod, and driving the driving gear to rotate through the tooth plate to open the control valve, allowing air to enter the filter box for filtration. At this time, the piston plate descends, driving the driving rod to descend. After the piston plate is lowered to a certain position, the driving rod contacts the driven rod below, thereby driving the tooth plate to descend, causing the driving gear to reverse and close the control valve. This cycle is repeated to achieve intermittent ventilation operations in the filter box and the leaching box, which can not only improve the cleaning effect of the filter net in the filter box, but also reduce the flow rate of the gas in the leaching box to a certain extent, thereby improving the leaching effect.

[0030] 6. During operation, the sealing covers arranged on the upper and lower sides of the filter box can be used to seal half of the filter cavity, while the other half of the filter cavity is normally dried. After a period of use, the fourth motor drives the circular plate to rotate, so that the position of the sealing cover is switched, so that the sealing cover seals the filter cavity after use for a period of time, and opens the other half of the filter cavity. At the same time, the hot air blower is turned on to dry the dry particles in the filter cavity after use, so that the dry particles can be reused, extending the service life of the dry particles. At the same time, there is no need to stop the machine for replacement, thereby ensuring work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] A spray plate 32 is fixed inside the leaching box 2, and a partition 36 is fixed at the lower end of the inside of the leaching box 2.

A blocking component cooperating with the water pumping port is provided on the first closing component.

[0047] With the above structure, when working, the water in the water cavity is extracted by the water pump 33, sprayed from the spray plate 32, and sent to the filter box 1 into the air for leaching operation. When working, the water extraction port in one of the water cavities is blocked by the blocking component, and the water extraction port in the other water cavity is opened, so that the water pump 33 will only extract water from one of the water cavities, and the other water cavity, when the blocking component blocks the water extraction port, uses the first sealing component to seal the upper end of the water cavity, so that the water in the water cavity can stand still. After standing still for a period of time, the second sealing component seals the lower part of the water cavity, so that The sediment produced by standing still is located below the second closed component, and then the sewage pipe 37 is opened for sewage discharge.

[0051] With the above structure, when the two first closing plates 43 move toward each other, the two semi-annular closing covers 48 will be driven to move toward each other through the connecting rod 47, so that while the first closing plate 43 closes the water cavity, the two semi-annular closing covers 48 close the water extraction holes 35 in the water cavity. The structure is simple, does not require additional drive, reduces the cost of the equipment, ensures the coordinated performance of the work, and reduces the occurrence of failure rates.

[0052] The second closing component includes a second U-shaped plate 50 fixed on the front and rear sides of the water chamber, the second U-shaped plate 50 is slidably connected to the inside of the first closing plate 43, the left and right sides of the second U-shaped plate 50 and the second closing plate 53 are in contact with the side wall of the water chamber, a third motor 51 is fixed to the inside of the first U-shaped plate 42, the output shaft end of the third motor 51 is fixedly connected to the third threaded rod 52, and the third threaded rod 52 is threadedly connected to the second closing plate 53.

[0053] With the above structure, when it is necessary to close the lower part of the water chamber after standing still, the third motor 51 drives the third threaded rod 52 to rotate, so that the front and rear second closing plates 53 move toward each other until the ends of the two closing plates collide, and then the sewage pipe 37 is opened to carry out sewage discharge. After the sewage discharge is completed, the third motor 51 is reversed, so that the two second closing plates 53 move in the opposite direction, thereby opening the lower part of the water chamber to facilitate the next work.

[0054] An annular air inlet seat 39 is fixed inside the leaching box 2, and the annular air inlet seat 39 is connected to the air outlet end of the filter box 1. A plurality of air jet pipes 40 are fixed to the lower end of the annular air inlet seat 39. The upper half of the air jet pipes 40 are arranged vertically downward, and the lower half of the air jet pipes 40 are arranged inclined, and the air outlet end of the air jet pipes 40 is inclined toward the center of the leaching box 2.

[0055] With the above structure, after the air in the filter box 1 enters the annular air inlet seat 39, it is sprayed downwardly through the air spray pipe 40, which not only allows the sprayed air to move downward for a distance under the action of inertia, thereby prolonging the contact time between air and water, but also allows the air to be sprayed obliquely toward the center, causing the air flow to collide, thereby accelerating the diffusion of the air, reducing the flow rate, and further improving the quality of leaching.

[0056] An air inlet pipe is fixed to the air inlet end of the filter box 1, a temporary storage box 4 is fixed to the other end of the air inlet pipe, a control valve 11 is fixed on the air inlet pipe, a driving gear 12 is fixed on the valve stem of the control valve 11, a suction fan 5 is fixed to the air inlet end of the temporary storage box 4, a dust hood 6 is fixed to the suction fan 5 through a hose, a spring 8 is fixed to the inside of the temporary storage box 4, a piston plate 7 is fixed to the other end of the spring 8, a slide rod 9 is fixed to the upper side of the piston plate 7, the upper end of the slide rod 9 extends out of the temporary storage box 4 and is fixed with a driving rod 10, a lifting rod 14 is slidably connected to the outside of the temporary storage box 4, two driven rods 15 are fixed on the lifting rod 14, the driving rod 10 is located between the two driven rods 15, a tooth plate 13 is fixed to the lower end of the lifting plate, and the tooth plate 13 is meshed with the driving gear 12.

[0057] With the above structure, the control valve 11 is closed at the beginning. When vacuuming, air enters the temporary storage box 4, squeezes the piston plate 7, and moves the piston plate 7 upward, thereby driving the driving rod 10 to move upward through the slide rod 9. When the driving rod 10 moves up to a certain height, the driving rod 10 contacts the upper driven rod 15, thereby driving the lifting rod 14 to rise through the driven rod 15, and driving the driving gear 12 to rotate through the tooth plate 13, so that the control valve 11 is opened, so that air enters the filter box 1 for filtering. At this time, the piston plate 7 descends, driving the driving rod 10 to descend. After the piston plate 7 is lowered to a certain position, the driving rod 10 contacts the lower driven rod 15, thereby driving the tooth plate 13 to descend, so that the driving gear 12 is reversed, and the control valve 11 is closed. In this cycle, intermittent ventilation operations in the filter box 1 and the leaching box 2 are realized, which can not only improve the cleaning effect of the filter screen 17 in the filter box 1, but also reduce the flow rate of the gas in the leaching box 2 to a certain extent, thereby improving the leaching effect.

[0058] A drying box 3 is fixed to the upper end of the leaching box 2, a filter box 54 is fixed inside the drying box 3, a plurality of annularly distributed filter chambers 55 are provided in the filter box 54, a fourth motor 56 is fixed to the upper end of the drying box 3, a rotating shaft 57 is fixed to the output shaft end of the fourth motor 56, two circular plates 58 are fixed to the rotating shaft 57, the two circular plates 58 are respectively located on the upper and lower sides of the filter box 54, a plurality of sealing covers 59 are fixed to the outer periphery of the circular plates 58, a hot air blower 60 is fixed to the lower sealing cover 59, a ventilation pipe 61 is fixed to the upper sealing cover 59, an exhaust pipe 63 is fixed to the drying box 3, an annular exhaust cover 62 is fixed to the lower end of the exhaust pipe 63, an annular sealing plate 64 is slidably connected to the lower side of the annular exhaust cover 62, and the ventilation pipe 61 is slidably connected to the annular sealing plate 64.

[0059] With the above structure, during operation, the sealing cover 59 arranged on the upper and lower sides of the filter box 54 can be used to seal half of the filter chamber 55, while the other half of the filter chamber 55 is normally dried. After a period of use, the fourth motor 56 drives the circular plate 58 to rotate, so that the position of the sealing cover 59 is switched, so that the sealing cover 59 seals the filter chamber 55 after a period of use and opens the other half of the filter chamber 55. At the same time, the hot air blower 60 is turned on to dry the dry particles in the filter chamber 55 after use, so that the dry particles can be reused, extending the service life of the dry particles. At the same time, there is no need to stop the machine for replacement, thereby ensuring work efficiency.

[0060] The working principle of the present invention is as follows: initially, the control valve 11 is closed. When vacuuming, air enters the temporary storage box 4, squeezing the piston plate 7, causing the piston plate 7 to move upward, thereby driving the driving rod 10 to move upward through the sliding rod 9. When the driving rod 10 moves up to a certain height, the driving rod 10 contacts the upper driven rod 15, thereby driving the lifting rod 14 to rise through the driven rod 15, and driving the driving gear 12 to rotate through the tooth plate 13, opening the control valve 11, allowing air to enter the filter box 1, and using the filter screen 17 inside the filter box 1 for multi-stage filtration, thereby achieving multi-stage filtration and purification of dust. While filtering, the first motor 21 is turned on, and the reciprocating forward and reverse rotation of the first motor 21 drives the cleaning brush 18 to move back and forth, pressing the filter screen 17 below. The attached foam and other impurities are scraped off and sent to the waste box 19 through the discharge port 20 to prevent the filter screen 17 from being blocked and affecting the filtering effect and efficiency. The setting of the triangular scraper 27 is that the triangular scraper 27 fits the filter screen 17 below it. During the movement, the foam and the like that are partially stuck in the mesh of the filter screen 17 can be scraped off and pressed down. The cleaning effect of the filter screen 17 can be further improved by cooperating with the cleaning brush 18 below. Then the filtered air is sent to the leaching box 2, and the water in the water cavity is extracted by the water pump 33 and sprayed from the spray plate 32 to send the air into the filter box 1 for leaching operation. During operation, the water extraction port in one of the water cavities is blocked by the blocking component, and the water extraction port in the other water cavity is blocked by the blocking component. The water inlet is opened so that the water pump 33 will only extract water from one of the water chambers, while for the other water chamber, while the sealing component seals the water pumping port, the first sealing component is used to seal the upper end of the water chamber so that the water in the water chamber can stand still. After standing still for a period of time, the second sealing component seals the lower part of the water chamber so that the sediment produced by standing still is located below the second sealing component. Then the sewage pipe 37 is opened to discharge sewage. After the sewage is discharged, the sewage pipe 37 is closed. Then the first sealing component, the second sealing component and the sealing component of the water chamber are opened. At the same time, the first sealing component and the sealing component in the other water chamber are opened, and the water pumping port and the upper end of the water chamber in the water chamber are sealed. The above sewage discharge operation is repeated, and the cycle is repeated. During leaching, the two water chambers are switched to discharge sewage to ensure the cleanliness of the water quality. While ensuring the leaching effect, there is no need to stop the machine for cleaning, which improves work efficiency. At the same time, the piston plate 7 descends, driving the drive rod 10 to descend. After the piston plate 7 is lowered to a certain position, the drive rod 10 contacts the driven rod 15 below, thereby driving the tooth plate 13 to descend, causing the drive gear 12 to reverse and close the control valve 11. This cycle is repeated to achieve intermittent ventilation operations in the filter box 1 and the leaching box 2, which can not only improve the cleaning effect of the filter screen 17 in the filter box 1, but also reduce the flow rate of the gas in the leaching box 2 to a certain extent, thereby improving the leaching effect. After the air is sprayed and filtered by spraying, the air is discharged.

[0061] In summary, by arranging components such as the cleaning brush 18, the waste box 19, the first closing mechanism and the second closing mechanism, the function of ensuring work efficiency while improving the quality of dust treatment is achieved.
