Description

Technical Field

[0001] This utility model relates to the field of dust suppression and cleaning technology, specifically to a dust suppression device for door and window manufacturing. Background Technology

[0002] In the door and window manufacturing process, cutting and sanding wooden boards are common processing steps. After cutting, the boards are precisely divided into the required sizes, while the sanding process makes the surface of the boards smooth and flat, laying the foundation for subsequent assembly and the quality of the finished product.

[0003] Immediately after processing, a lot of dust often remains on the surface of the board. When personnel handle or move the processed board, the dust that was originally attached to the surface of the board will lose its adhesion and quickly disperse into the working environment. If workers are in such an environment for a long time, it will have a great impact on their health.

[0004] Therefore, a dust suppression device for door and window production is proposed. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 5 As shown, a dust suppression device for door and window production includes a conveyor workbench body 1, on which a cleaning mechanism 3 for cleaning the surface of the board material is provided, such as... Figure 1 , Figure 2 As shown, specifically, it includes a protective shell 301, a mounting frame 303, and cleaning brush rollers 307. The mounting frame 303 is fixedly installed on the top of the conveying worktable body 1. The protective shell 301 is fixedly installed on one side wall of the mounting frame 303. The cleaning brush rollers 307 are rotatably installed on the inner side wall of the protective shell 301. There are two sets of cleaning brush rollers 307 arranged in parallel. The rotation shafts of the two sets of cleaning brush rollers 307 pass through one side wall of the mounting frame 303 and are respectively fixedly connected to a synchronous pulley 308 and a second gear 306. A first gear 305 is rotatably installed on one side of the second gear 306. The first gear 305 and the second gear 306 are meshed. A driven wheel 304 is fixedly installed on one side wall of the first gear 305. A motor 302 is fixedly installed inside the protective shell 301. The output end of the motor 302... A synchronous belt 309 is fixedly connected to one side wall of the synchronous pulley 308 and the driven pulley 304. More specifically, the synchronous pulley 308 is driven by the synchronous belt 309 to rotate the driven pulley 304 through the rotation of the motor 302. The rotation of the driven pulley 304 synchronously drives the second gear 306, which meshes with the first gear 305, to rotate. This causes the two sets of cleaning brush rollers 307 to rotate in opposite directions, cleaning the surface of the board material conveyed by the conveying workbench body 1. At the same time, because the two sides rotate in opposite directions, the dust adhering to the surface of the board material is greatly reduced when it is discharged. The opposite rotation also makes it difficult for dust inside the mounting frame 303 to escape to the outside, allowing it to be better sucked up by the second dust suction head 6015, improving the dust reduction effect. A dust collection mechanism 4 is provided below one side of the conveying workbench body 1. Figure 2 , Figure 3As shown, specifically, it includes a collection funnel 401 and a box 407. The box 407 is fixedly installed on one side of the bottom plate of the conveying workbench body 1. A sealing door 404 is hinged on the box 407. There are two sets of sealing doors 404, which are symmetrically arranged. Each set of sealing doors 404 is fixedly provided with a limit bracket 408. Each set of limit brackets 408 is provided with a groove. A limit rotating rod 405 is rotatably installed on one set of limit brackets 408. The limit rotating rod 405 is adapted to the groove. The collection funnel 401 is fixedly installed on the through hole at the top of the box 407. A through opening 403 is opened on one side wall of the collection funnel 401. A baffle 402 is provided above the through opening 403. A collection box 406 is placed inside the box 407. More specifically, after being processed by the cleaning mechanism 3, the collection box 406 is used to collect the contents of the box. When conveying boards, the surface of the conveyor belt on the main body 1 of the conveying workbench may have large wood chips and some residual dust. When the conveyor belt rotates to the side of the collecting funnel 401, the larger wood chips fall directly into the collecting box 406 through the collecting funnel 401, while the residual dust is sucked into the water tank 601 through the opening 403. The baffle 402 set on the opening 403 prevents particles from falling directly into the opening 403. The sealing door 404 improves the sealing of the box 407. The limiting rotation rod 405 on the limiting bracket 408 locks the two sets of limiting brackets 408, so that the sealing door 404 can fit more tightly with the box 407. At the same time, the smoke and dust generated in the collecting box 406 can also be sucked into the dust suppression mechanism 6 through the opening 403 for treatment. The bottom plate of the conveying workbench 1 is provided with a dust suppression mechanism 6 for adsorbing dust. Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, specifically, the dust suppression mechanism 6 includes a first suction head 2, a cover plate 11, a water tank 601, a drain outlet 602, and a placement seat 609. The placement seat 609 is fixedly installed on the base plate of the conveying workbench body 1. The cover plate 11 is fixedly installed on the placement seat 609. The drain outlet 602 is located on one side wall of the water tank 601. A strip groove 13 is provided on the upper inner side wall and one outer side wall of the cover plate 11. A sealing strip 5 is placed in the strip groove 13. A sliding groove 6010 is provided on the placement seat 609. A slider 6011 is fixedly installed on both side walls of the water tank 601. The slider 6011 is slidably disposed with the sliding groove 6010. A first connecting rod is provided on the cover plate 11. The first connection port 9 is connected to the air outlet of the collecting funnel 401. A dust settling box 606 is fixedly installed above the second connection port 10. A spray head 605 is installed inside the dust settling box 606. The water inlet of the spray head 605 penetrates one side wall of the dust settling box 606 and is connected to an external water source. A branch pipe 607 is connected to one side wall of the dust settling box 606. The bottom of the branch pipe 607 is connected to the drying and filtering mechanism 7. A sealing baffle 6013 and a handle 604 are fixedly installed from top to bottom on one outer side wall of the water tank 601. A rectangular groove 6012 is opened on the sealing baffle 6013. The rectangular groove 6012 is connected to the handle 604 on one outer side wall of the cover plate 11. The sealing strip 5 is adapted to the first dust suction head 2, which is installed on the side wall of the top of the conveying workbench body 1. There are two sets of the first dust suction heads 2, which are symmetrically arranged. The first dust suction heads 2 on both sides are connected to the connecting square tubes 6016. The mounting bracket 303 is provided with a second dust suction head 6015, which is connected to the connecting square tubes 6016. The two sets of connecting square tubes 6016 are connected to the collecting funnel 401. The water tank 601 is fixedly provided with a detour baffle 6014. There are multiple sets of detour baffles 6014, which are staggered. The top of the multiple sets of detour baffles 6014 is flush with the top of the water tank 601. The top of the water tank 601 is flush with the cover plate 1. The bottom of the 1 is attached to the base. A stud 608 is threaded onto one outer side wall of the placement base 609. A limiting block 603 is fitted onto the stud 608. More specifically, by drawing the dust from the collection mechanism 4 into the water tank 601, the dust comes into contact with the water in the water tank 601, and coarse dust particles can quickly settle. The remaining dust then flows into the dust settling box 606, where the spray nozzles 605 spray out a water curtain or water mist layer. The dust is wetted, condensed, and settles into the water tank 601 as it passes through the water curtain. This graded treatment method improves the efficiency and quality of dust treatment, allowing the dust to be removed more thoroughly and reducing dust pollution to the environment. The water in the water tank 601 is discharged through the drain outlet 602.Simultaneously, water is introduced through the spray head 605, ensuring the water in the tank 601 maintains good adsorption capacity. The mixed liquid discharged through the drain port 602 is collected for further treatment. The sealing strip 5 on the cover plate 11 adheres to the side wall of the tank 601, and one side of the sealing baffle 6013 on the tank 601 adheres to the sealing strip 5, further improving the device's sealing performance and suction efficiency. The handle 604 facilitates pulling out the tank 601 for internal cleaning. The detour baffle 6014 and spray head 605 in the tank 601 classify and treat dust, causing it to settle rapidly within the tank, further reducing airborne dust content, significantly improving air quality in the working environment, reducing the amount of dust inhaled by workers, and mitigating the impact on their health. The first suction head 2 initially adsorbs the dust generated during grinding on the conveyor workbench body 1, improving the working environment. Simultaneously, the second suction head 6015 draws the cleaned dust from the mounting frame 303 through the connecting square tube 6016 into the collection funnel 401, reducing the amount of dust adhering to the board surface and causing pollution during handling, thus improving the cleanliness of the board surface. The staggered, alternating baffles 6014 increase the contact area and time between the dust and the water in the water tank 601 during suction, improving the dust settling effect. Furthermore, tightening the studs 608 causes the limiting block 603 to compress and limit the water tank 601, improving the sealing between the water tank 601, the placement seat 609, and the cover plate 11. One side of the dust settling mechanism 6 is connected to a drying and filtering mechanism 7 for adsorbing moisture, such as… Figure 3 , Figure 4As shown, specifically, when the dust collector body 8 sucks up dust, the gas drawn in through the branch pipe 607 flows through the filter box 701. First, it is filtered by the filter plate 707, which performs preliminary filtration of dust particles with less moisture in the gas. Then, the coarsely filtered gas is drawn into the dehumidification box 705 through the first connecting pipe 702. It then passes through the placement partition 706 and the filter screen and desiccant placed by personnel for further dehumidification and filtration. Furthermore, the filter box 701 is periodically cleaned, and the filter screens and desiccant on the filter plate 707 and placement partition 706 are used for further cleaning. The desiccant is replaced to improve its filtration and dehumidification effect. The drying and filtration mechanism 7 includes a filter box 701 and a fixed bracket 703. The fixed bracket 703 is fixedly installed on the base plate of the conveying workbench body 1. A dehumidification box 705 is fixedly installed on the fixed bracket 703. One side of the filter box 701 is connected to the air outlet of the branch pipe 607, and the other side of the filter box 701 is connected to a first connecting pipe 702. A filter plate 707 is placed inside the filter box 701. The other end of the first connecting pipe 702 is connected to the bottom of the dehumidification box 705. A second connecting pipe 704 is provided above the other side wall of the dehumidification box 705, connected to one side wall. The air outlet of the second connecting pipe 704 is connected to the dust collector body 8. The dehumidification box 705 is provided with multiple sets of partitions 706. More specifically, when the dust collector body 8 sucks up dust, the gas sucked up through the branch pipe 607 flows through the filter box 701. First, it is filtered by the filter plate 707 to initially filter the dust particles with less moisture in the gas. Then, the coarsely filtered gas is discharged through the first connecting pipe 702. The gas is drawn into the dehumidification box 705, passes through the filter screen and desiccant placed by personnel in the partition 706, and is further dehumidified and filtered. The filtration and dehumidification effect is improved by periodically cleaning the filter box 701 and replacing the filter screen and desiccant on the filter plate 707 and the partition 706. One end of the drying and filtering mechanism 7 is connected to the dust collector body 8, and the dust outlet end of the dust collector body 8 is connected to the dust collection bag 12. The collection mechanism 4 is connected to the dust suppression mechanism 6, and the conveying workbench body 1 is equipped with a controller 14.

[0026] In summary: First, the workers sand the boards on the conveyor workbench body 1. Then, the controller 14 controls the rotation of the conveyor workbench body 1 to move the boards into the cleaning mechanism 3. At this time, the surface of the boards is cleaned in the cleaning mechanism 3. Simultaneously, the dust removal mechanism 6 in the cleaning mechanism 3 sucks up the dust generated within the cleaning mechanism 3. The boards cleaned by the cleaning mechanism 3 are then conveyed to one side by the conveyor workbench body 1. At this point, workers pick them up. At this time, there may be wood chips remaining on the conveyor belt of the conveyor workbench body 1. As the conveyor workbench body 1 continues to rotate, the remaining debris falls off. The dust is collected in the collection mechanism 4 and sucked out by the dust settling mechanism 6. The dust is then settled by the dust settling mechanism 6. The gas sucked out by the dust settling mechanism 6 is then filtered and dehumidified by the drying and filtration mechanism 7. Finally, the filtered gas is sucked out to the dust outlet and discharged into the dust collection bag 12 by the dust collector body 8. Through the cooperation of the cleaning mechanism 3 and the dust settling mechanism 6, the dust remaining on the surface of the board after sanding can be quickly removed, preventing it from escaping into the working environment during personnel handling and transportation. This further reduces the dust content in the air and significantly improves the air quality of the working environment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
