Description

Technical Field

[0001] This invention relates to the field of dust removal equipment technology, specifically to a waste gas dust removal and purification device for the production and processing of wooden furniture. Background Technology

[0002] In the current technology, the production and processing of wooden furniture generally involves processes such as cutting, shaving, planing, and grinding. These processes generate a large amount of dust, which floats in the air. If not handled properly, the dust can be inhaled by the operators through their respiratory tract, thus causing certain harm to their health. Summary of the Invention

[0003] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a waste gas dust removal and purification device for wooden furniture production and processing, which has the advantages of being able to filter and spray waste gas, thereby reducing the health hazards to personnel.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a waste gas dust removal and purification device for wooden furniture production and processing, comprising:

[0005] Spray purification components;

[0006] Dust inlet filter assembly;

[0007] The dust removal roller assembly, the dust inlet filter assembly, and the dust removal roller assembly are respectively arranged on opposite sides of the spray purification assembly;

[0008] The spray purification component includes a spray box, a spray plate is movably installed on the top of the spray box, and a scraper sleeve is fitted on the outer peripheral wall of the spray plate to contact the inner wall of the spray box.

[0009] The dust inlet filter assembly includes a filter box connected to the spray box. An arc-shaped guide plate is provided on the bottom surface of the filter box. The arc-shaped opening of the arc-shaped guide plate faces the top of the filter box. The filter plate is rotatably installed inside the arc-shaped opening of the arc-shaped guide plate. A dust inlet hole is provided on the side wall of the filter box away from the spray box.

[0010] The dust removal roller assembly includes a dust removal box connected to the spray box, a dust removal roller is rotatably installed inside the dust removal box, and an exhaust hole is provided on the side wall of the dust removal box away from the spray box.

[0011] Preferably, a pushing cylinder is vertically installed on the top surface of the spray box. The piston rod of the pushing cylinder moves through the top surface of the spray box and is connected to the spray plate. Multiple nozzles are arranged in an array on the bottom surface of the spray plate. The spray plate is connected to a water tank with a water pump located outside the spray box. The spray plate can be pushed to different positions in the spray box as needed by pushing the cylinder, so as to achieve different spraying effects on the exhaust gas in the spray box.

[0012] Preferably, the filter box is horizontally provided with a dust inlet duct connected to the dust inlet hole, and the arc-shaped guide plate is provided with a horizontal groove connected to the dust inlet duct at the opening end away from the dust cleaning box. The filter plate is rotatably arranged in the arc-shaped opening at the end of the arc-shaped guide plate away from the dust inlet duct, so that the external exhaust gas can enter the dust inlet duct through the dust inlet hole and then enter the arc-shaped opening of the arc-shaped guide plate. After being filtered by the filter plate, it enters the spray box for spray treatment, which is beneficial to remove particulate impurities in the exhaust gas.

[0013] Preferably, the filter plate comprises:

[0014] The rotating rod is horizontally positioned within the arc-shaped opening of the arc-shaped guide plate, and the rotating rod is coaxial with the arc-shaped guide plate.

[0015] The fan-shaped plate is set on the outer peripheral wall of the rotating rod. The end of the fan-shaped plate away from the rotating rod is arc-shaped. The end of the fan-shaped plate away from the rotating rod is in contact with the inner wall of the arc-shaped opening of the arc-shaped guide plate away from the dust inlet duct.

[0016] The rotating motor is installed on the inner wall of the filter box. The rotating rod is coaxially sleeved on the outside of the output shaft of the rotating motor. The external exhaust gas enters the arc-shaped opening of the arc-shaped guide plate, and after being filtered by the filter plate, it enters the spray box for spray treatment, which is beneficial to remove particulate impurities in the exhaust gas.

[0017] Preferably, the fan-shaped plate is horizontally arranged in the arc-shaped opening of the arc-shaped guide plate. The bottom surface of the fan-shaped plate is open. A screen plate with a matching shape is arranged inside the fan-shaped plate. A plate groove is provided at the end of the fan-shaped plate away from the rotating rod. A second horizontal groove is provided at the opening end of the arc-shaped guide plate near the spray box. The plate groove and the second horizontal groove are connected. The spray box and the dust removal box are connected by a connecting groove provided on the side wall of the dust removal box. External exhaust gas enters into the arc-shaped opening of the arc-shaped guide plate, passes through the opening on the bottom surface of the fan-shaped plate, enters into the fan-shaped plate for filtration, and then enters the spray box for spraying treatment in sequence through the plate groove, the second horizontal groove, and the connecting groove at the end of the fan-shaped plate away from the rotating rod.

[0018] Preferably, the connecting trough is vertically arranged between the dust cleaning box and the spray box, and the two ends of the opening of the connecting trough are located in the dust cleaning box and the spray box, respectively. The exhaust gas sprayed in the spray box enters the dust cleaning box through the connecting trough for further dust cleaning treatment, which helps to improve the quality of the exhaust gas after treatment.

[0019] Preferably, the dust removal roller comprises:

[0020] The drive motor is movably embedded in the bottom surface of the dust collection box;

[0021] The roller body is coaxially sleeved on the outside of the output shaft of the drive motor, and the inside of the roller body is a filter mesh structure.

[0022] Multiple ash collection troughs are provided, and the multiple ash collection troughs are evenly distributed along the outer peripheral wall of the roller body. The drive motor drives the roller body to rotate at low speed, so that the exhaust gas can enter the roller body through each ash collection trough for filtration, preventing one or more ash collection troughs from becoming blocked and affecting the filtration effect.

[0023] Preferably, a horizontal cylinder is also provided on the bottom surface of the dust cleaning box away from the end of the connecting groove, and the drive motor is mounted on the piston rod of the horizontal cylinder. A cylindrical cover adapted to the position of the roller is vertically arranged on the top surface of the dust cleaning box. The bottom surface of the cylindrical cover is open, and the inner diameter of the cylindrical cover is larger than the outer diameter of the roller. When the roller needs to be cleaned, the horizontal cylinder can drive the drive motor and the roller to move away from the connecting groove, and then the cylindrical cover can be moved to the outside of the roller. At this time, the drive motor can be started to drive the roller to rotate at high speed, which can make the water adsorbed on the roller or the particulate impurities adhering to the surface of the roller fall onto the inner wall of the cylindrical cover and then fall off, thereby improving the cleanliness of the roller.

[0024] Preferably, a lifting cylinder is provided on the top surface of the dust removal box, and the top surface of the cylinder cover is connected to the piston rod of the lifting cylinder, so that the cylinder cover can be moved to the outside of the roller body. When the drive motor is started to drive the roller body to rotate at high speed, the water adsorbed on the roller body or the particulate impurities adhering to the surface can be thrown off onto the inner wall of the cylinder cover and then fall off, thereby improving the cleanliness of the roller body.

[0025] Preferably, the opening end of the connecting groove inside the dust removal box is arc-shaped, the arc shape of the opening of the connecting groove inside the dust removal box is adapted to the outer diameter of the roller body, the arc shape of the opening of the connecting groove inside the dust removal box abuts against the outer peripheral wall of the roller body, and the height of the connecting groove is the same as the height of the roller body, which helps to reduce the gap generated when the roller body and the connecting groove come into contact, and is beneficial to improving the treatment effect of the exhaust gas after spraying.

[0026] The beneficial effects of this invention are as follows: 1. The exhaust gas generated during the production and processing of wooden furniture can first be filtered through the filter plate in the filter box to remove particulate impurities in the exhaust gas, and then enter the spray box for spraying treatment, thereby greatly reducing the particulate content in the exhaust gas. Finally, it is filtered again through the roller in the dust removal box, thereby reducing the harm to operators.

[0027] 2. By rotating the filter plate within the arc-shaped opening of the arc-shaped guide plate, particulate impurities adhering to the arc-shaped opening of the arc-shaped guide plate can be scraped off. This helps to clean up the particulate impurities accumulated within the arc-shaped opening of the arc-shaped guide plate, reducing the content of particulate impurities in the exhaust gas flowing into the dust collection box and improving the quality of the treated exhaust gas.

[0028] 3. When the roller body needs to be cleaned, the horizontal cylinder can drive the drive motor and the roller body to move away from the connecting groove. Then, the lifting cylinder can be activated to push the cylinder cover closer to the roller body, so that the cylinder cover moves to the outside of the roller body. The drive motor can be activated to drive the roller body to rotate at high speed, so that the water adsorbed on the roller body or the particulate impurities adhering to the surface can be thrown off onto the inner wall of the cylinder cover and then fall off along the inner wall of the cylinder cover, thereby improving the cleanliness of the roller body and improving the filtration quality before the exhaust gas is discharged.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figures 1 to 5 As shown, this invention provides a dust removal and purification device for waste gas in the production and processing of wooden furniture, including a spray purification component 1; a dust inlet filter component 2 and a dust removal roller component 3 are respectively disposed on opposite sides of the spray purification component 1; the spray purification component 1 includes a spray box 11, a spray plate 12 is movably disposed on the top of the spray box 11, and a scraper sleeve 13 is sleeved on the outer peripheral wall of the spray plate 12 and contacts the inner wall of the spray box 11; the dust inlet filter component 2 includes a filter that communicates with the spray box 11. The filter box 21 has an arc-shaped guide plate 22 on its bottom surface. The arc-shaped opening of the arc-shaped guide plate 22 faces the top of the filter box 21. A filter plate 23 is rotatably arranged inside the arc-shaped opening of the arc-shaped guide plate 22. A dust inlet hole 24 is provided on the side wall of the filter box 21 away from the spray box 11. The dust cleaning roller assembly 3 includes a dust cleaning box 31 connected to the spray box 11. A dust cleaning roller 32 is rotatably arranged inside the dust cleaning box 31. An exhaust hole 33 is provided on the side wall of the dust cleaning box 31 away from the spray box 11.

[0042] The exhaust gas enters the filter box 21 through the dust inlet 24 and then enters the arc-shaped opening of the arc-shaped guide plate 22. After being filtered by the filter plate 23, it enters the spray box 11 and is sprayed by the spray plate 12, which can reduce the particulate content in the exhaust gas. After being sprayed, the exhaust gas enters the dust removal box 31, and is then filtered by the dust removal roller 32 before being discharged through the exhaust port 33.

[0043] The filter plate 23 can be rotated within the arc-shaped opening of the arc-shaped guide plate 22, so that the particulate matter in the exhaust gas adhering to the arc-shaped opening of the arc-shaped guide plate 22 can be scraped off by the filter plate 23, which facilitates subsequent cleaning.

[0044] The spray plate 12 can move up and down inside the spray box 11, which can simultaneously drive the scraper sleeve 13 to move up and down. Thus, the scraper sleeve 13 can scrape off the particulate matter and spray water adhering to the inner wall of the spray box 11, thereby improving the quality of the treated waste gas.

[0045] Example 2

[0046] Based on Example 1, such as Figures 1 to 4 As shown, a push cylinder 14 is vertically installed on the top surface of the spray box 11. The piston rod of the push cylinder 14 moves through the top surface of the spray box 11 and is connected to the spray plate 12. Multiple nozzles are arranged in an array on the bottom surface of the spray plate 12. The spray plate 12 is connected to a water tank with a water pump located outside the spray box 11. The spray plate 12 can be pushed to different positions in the spray box 11 by the push cylinder 14 as needed, so that different spraying effects can be achieved on the exhaust gas in the spray box 11. The spray plate 12 can be moved to the top surface of the spray box 11 by the push cylinder 14, at which time the spraying area is the largest. Alternatively, the spray plate 12 can be moved to the bottom surface of the spray box 11, so that the spray plate 12 is located at the upper position of the horizontal groove 236 near the opening end of the arc guide plate 22, at which time the space in the spray box 11 becomes smaller under the action of the spray plate 12.

[0047] When the spray plate 12 moves up and down inside the spray box 11, the scraper sleeve 13 fitted on the outer peripheral wall of the spray plate 12 can move up and down synchronously with the spray plate 12, so as to scrape off the particles or spray water adhering to the inner wall of the spray box 11 (that is, under the action of the spray plate 12, the particles or spray water adhering to the inner wall of the spray box 11 are scraped to the bottom of the spray box 11. The bottom of the spray box 11 is equipped with a drain pipe, which facilitates the collection and treatment of the scraped particles or spray water adhering to the inner wall of the spray box 11, thereby improving the cleanliness of the spray box 11).

[0048] The shape of the spray plate 12, the shape of the scraper sleeve 13, and the shape of the inside of the spray box 11 are the same, which is conducive to the scraper sleeve 13 making better contact with the inner wall of the spray box 11, thereby improving the effect of scraping off the particles or spray water adhering to the inner wall of the spray box 11.

[0049] Example 3

[0050] Based on Example 1, such as Figures 1 to 2 , Figures 4 to 5As shown, a dust inlet duct 25, connected to the dust inlet hole 24, is horizontally arranged inside the filter box 21. A horizontal groove 26, connected to the dust inlet duct 25, is provided at the open end of the arc-shaped guide plate 22 away from the dust removal box 31. The filter plate 23 is rotatably arranged in the arc-shaped opening at the end of the arc-shaped guide plate 22 away from the dust inlet duct 25. The filter plate 23 includes a rotating rod 231, which is horizontally arranged in the arc-shaped opening of the arc-shaped guide plate 22, and the rotating rod 231 is coaxial with the arc-shaped guide plate 22. A fan-shaped plate body 232 is arranged on the outer peripheral wall of the rotating rod 231. The end of the fan-shaped plate body 232 away from the rotating rod 231 is arc-shaped, and the end of the fan-shaped plate body 232 away from the rotating rod 231 is parallel to the arc-shaped guide plate 22 away from the dust inlet duct 25. The inner walls of the arc-shaped openings at the ends are in contact; the rotating motor 233 is installed on the inner wall of the filter box 21, and the rotating rod 231 is coaxially sleeved on the outside of the output shaft of the rotating motor 233; the fan-shaped plate 232 is horizontally installed in the arc-shaped opening of the arc-shaped guide plate 22, the bottom surface of the fan-shaped plate 232 is open, and a screen plate 234 with a matching shape is installed inside the fan-shaped plate 232. The end of the fan-shaped plate 232 away from the rotating rod 231 is provided with a plate groove 235, and the arc-shaped guide plate 22 is provided with a horizontal groove 236 near the opening end of the spray box 11. The plate groove 235 and the horizontal groove 236 are connected. The spray box 11 and the dust removal box 31 are connected by a connecting groove 4 provided on the side wall of the dust removal box 31.

[0051] External exhaust gas enters the dust inlet duct 25 through the dust inlet hole 24, then enters the arc-shaped opening of the arc-shaped guide plate 22 through the horizontal groove 26. After being filtered by the filter plate 23 (i.e., after the exhaust gas enters the arc-shaped guide plate 22 through the horizontal groove 26, it can enter the fan-shaped plate 232 through the bottom opening and be filtered by the screen plate 234), and then the filtered exhaust gas is discharged through the plate groove 235 at the end of the fan-shaped plate 232 away from the rotating rod 231. It then enters the spray box 11 through the horizontal groove 236 for spray treatment. After being sprayed, the exhaust gas enters the dust removal box 31 through the connecting groove 4 for dust removal.

[0052] When the rotating motor 233 is started, the rotating rod 231 and the filter plate 23 can rotate simultaneously within the arc-shaped opening of the arc-shaped guide plate 22. This allows the particulate matter in the exhaust gas adhering to the arc-shaped opening of the arc-shaped guide plate 22 to be scraped off through the end of the filter plate 23 away from the rotating rod 231. This facilitates subsequent cleaning and avoids the accumulation of a large amount of particulate matter in the arc-shaped guide plate 22, which is beneficial to improving the quality of exhaust gas treatment.

[0053] Example 4

[0054] Based on Example 1, such as Figures 1 to 2 , Figures 6 to 8As shown, the connecting groove 4 is vertically arranged between the dust removal box 31 and the spray box 11, and the two ends of the opening of the connecting groove 4 are located inside the dust removal box 31 and the spray box 11, respectively; the dust removal roller 32 includes a drive motor 321, which is movably embedded in the bottom surface of the dust removal box 31; the roller body 322 is coaxially sleeved outside the output shaft of the drive motor 321, and the inside of the roller body 322 is a filter mesh structure; multiple dust collection grooves 323 are provided, and the multiple dust collection grooves 323 are arranged along the roller body 322. The outer peripheral walls are evenly spaced; a horizontal cylinder 324 is also provided in the bottom surface of the dust cleaning box 31 away from the end of the connecting groove 4, and the drive motor 321 is set on the piston rod of the horizontal cylinder 324. A cylindrical cover 5 adapted to the position of the roller body 322 is vertically provided on the top surface of the dust cleaning box 31. The bottom surface of the cylindrical cover 5 is open, and the inner diameter of the cylindrical cover 5 is larger than the outer diameter of the roller body 322. A lifting cylinder 51 is provided on the top surface of the dust cleaning box 31, and the top surface of the cylindrical cover 5 is connected to the piston rod of the lifting cylinder 51.

[0055] After being sprayed in the spray box 11, the exhaust gas enters the dust removal box 31 through the connecting groove 4. At the same time, the drive motor 321 is started to drive the roller body 322 to rotate at low speed, so that the exhaust gas enters the roller body 322 through each ash collection groove 323 for filtration. The particulate impurities in the exhaust gas can adhere to the inside of the roller body 322 (at the same time, a certain amount of water vapor in the exhaust gas can be adsorbed inside the roller body 322), preventing one or more ash collection grooves 323 from becoming blocked and affecting the filtration effect. The filtered exhaust gas is finally discharged through the exhaust hole 33 on the side wall of the dust removal box 31 away from the spray box 11.

[0056] When the roller 322 needs to be cleaned, the horizontal cylinder 324 can drive the drive motor 321 and the roller 322 to move away from the connecting groove 4 (so that the position of the cover 5 corresponds vertically to the position of the roller 322). Then, the lifting cylinder 51 is activated to push the cover 5 closer to the roller 322, so that the cover 5 moves to the outside of the roller 322 (that is, the cover 5 is fitted on the outside of the roller 322, at which time the inner peripheral wall of the cover 5 does not contact the outer peripheral wall of the roller 322). At this time, the drive motor 321 can be activated to drive the roller 322 to rotate at high speed, so that the water adsorbed on the roller 322 or the particulate impurities adhering to the surface are thrown off onto the inner wall of the cover 5 and then fall off along the inner wall of the cover 5, thereby improving the cleanliness of the roller 322.

[0057] The opening end of the connecting groove 4 inside the dust removal box 31 is arc-shaped. The arc shape of the opening of the connecting groove 4 inside the dust removal box 31 is adapted to the outer diameter of the roller body 322. The arc shape of the opening of the connecting groove 4 inside the dust removal box 31 abuts against the outer peripheral wall of the roller body 322, and the height of the connecting groove 4 is the same as the height of the roller body 322. This helps to reduce the gap generated when the roller body 322 and the connecting groove 4 come into contact, which is beneficial to improving the treatment effect of the sprayed exhaust gas. That is, the exhaust gas after spraying can enter the roller body 322 through the dust collection groove 323 for secondary filtration, thereby improving the treatment effect of the exhaust gas.

[0058] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
