Description

Technical Field

[0001] This invention belongs to the field of workshop dust removal, specifically relating to a dust removal device for use in a production workshop for medical protective equipment. Background Technology

[0002] As a crucial barrier to preventing the spread of viruses, protective equipment for medical personnel requires an extremely high level of cleanliness in its production environment. The processing of protective clothing fabrics generates a large amount of fiber debris and dust. If these particles adhere to the material surface, they not only affect the product's appearance but can also become carriers of bacteria and viruses. Protective equipment is typically sterilized with ethylene oxide or gamma rays before leaving the factory. If dust removal is not thorough during production, accumulated dust inside the equipment may breed microorganisms.

[0003] Chinese Patent CN221432485U, published on July 30, 2024, discloses a dust removal device for watchmaking workshops. The device includes a dust removal box, with a first chamber on the left side separated by a partition, and a second chamber on the right side separated by a partition. A dust removal mechanism is fixedly connected inside the dust removal box, and a base is fixedly connected to the bottom of the dust removal box. Universal wheels are fixedly connected to the four corners of the bottom of the base, and a push handle is fixedly connected to the right side of the top of the base. An adjustment mechanism is fixedly connected to the surface of the dust removal box. The dust removal mechanism includes an atomizing component and an absorption component, and the adjustment mechanism includes a rotating component and a fixing component.

[0004] In the aforementioned application documents, water mist is sprayed into the air through an atomizing component to perform the corresponding dust removal operation. However, it takes a certain amount of time for the dust adsorbed on the water droplets to fall to the ground, which affects the dust removal efficiency. When the dust is removed by first extracting the dust and then spraying water to remove the dust, the sprayed water mist is difficult to cover the dust inside the device, which still affects its dust removal efficiency.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, please refer to Figures 1-4 A dust removal device for a medical protective equipment production workshop includes a dust removal chamber 100, a dust inlet 200 on the side of the dust removal chamber 100, a liquid inlet 300 on the top of the dust removal chamber 100, an output hose 400, and a stirring rod 500 driven by a servo motor installed inside the dust removal chamber 100. Dust from the production workshop is input into the dust removal chamber 100 through the dust inlet 200, and dust removal liquid is input through the liquid inlet 300 to perform corresponding dust removal operations on the dust in the dust removal chamber 100. The stirring rod 500 driven by the servo motor is activated to slowly rotate, preventing the dust and dust removal liquid in the dust removal chamber 100 from settling and separating. The mixture in the dust removal chamber 100 is then discharged sequentially through the output hose 400.

[0022] A rotating rod 601 is fixedly connected inside the stirring rod 500. When the stirring rod 500 rotates, it drives the rotating rod 601 fixedly connected to it to rotate.

[0023] A pipe connector 602 is rotatably connected to the bottom of the infusion port 300. An infusion chamber 603 is fixedly connected to the bottom of the pipe connector 602. The infusion chamber 603 is located at the top of the rotating rod 601, and the infusion chamber 603 and the rotating rod 601 are in a fixed state. When the rotating rod 601 rotates, because the bottom of the infusion port 300 is rotatably connected to the pipe connector 602, and the infusion chamber 603 assembled at the bottom of the pipe connector 602 is fixedly connected to the rotating rod 601, the rotating rod 601 drives the infusion chamber 603 to rotate synchronously during the rotation process.

[0024] A pipe connector 604 is rotatably connected to the bottom of the infusion chamber 603. A spray head 608 is mounted on the bottom of the pipe connector 604. A brush plate 609 is fixedly connected to the inner wall of the dust removal chamber 100. A transmission component for transmission is assembled between the pipe connector 604 and the spray head 608. The transmission component includes a gear 605 fixed to the outside of the pipe connector 604. When the infusion chamber 603 rotates, it drives the pipe connector 604, which is rotatably connected to it, to rotate synchronously. This causes the gear 605, which is fixedly connected to it, to rotate synchronously during the revolution of the pipe connector 604.

[0025] A fixed rod 606 is fixedly connected inside the dust collection chamber 100. A gear ring 607 is fixedly connected to the side of the fixed rod 606, and the gear ring 607 meshes with a gear 605. When the gear 605 revolves, it is restricted by the gear ring 607, causing it to rotate synchronously on its own axis during the revolution. The rotating gear 605 drives the pipe joint 604 fixedly connected to it to rotate, which in turn drives the spray head 608 mounted at its bottom to revolve and rotate synchronously. This causes the dust collection liquid to be sprayed out through the rotating spray head 608, increasing the coverage of the dust by the dust collection liquid and thus improving the dust collection efficiency of the device.

[0026] In practical use, the aforementioned equipment introduces dust from the production workshop into the dust collection chamber 100 through the dust inlet 200 and dust removal liquid through the liquid inlet 300 to perform corresponding dust removal operations on the dust in the dust collection chamber 100. The stirring rod 500, driven by a servo motor, is activated to slowly rotate, preventing the dust and dust removal liquid in the dust collection chamber 100 from settling and separating. The mixture in the dust collection chamber 100 is then discharged sequentially through the output hose 400. The rotating stirring rod 500 drives the rotating rod 601, which is fixedly connected to it, to rotate. A pipe connector 602 is rotatably connected to the bottom of the liquid inlet 300, and the liquid collection chamber 603, assembled at the bottom of the pipe connector 602, is fixedly connected to the rotating rod 601. This ensures that as the rotating rod 601 rotates, it drives the liquid collection chamber 603 to rotate synchronously. The liquid tank 603 can drive the pipe joint 604 connected to it to rotate synchronously. During the revolution of the pipe joint 604, the gear 605 fixedly connected to it will also rotate synchronously. The gear 605 is restricted by the gear ring 607 meshing with it, so that the gear 605 rotates synchronously during the revolution. The rotating gear 605 can drive the pipe joint 604 fixedly connected to it to rotate, so that the pipe joint 604 drives the spray head 608 assembled at its bottom to rotate synchronously. The dust removal liquid input through the inlet 300, pipe joint 602, liquid tank 603 and pipe joint 604 is then output through the spray head 608. During the rotation of the liquid tank 603, its top is brushed by the brush plate 609, which brushes off any dust that may remain there.

[0027] Example 2, please refer to Figures 3-6 Based on Embodiment 1, a dust collection assembly 700 is mounted on the side of the dust collection chamber 100. The dust collection assembly 700 includes a bevel gear 701 fixed to the bottom of a rotating rod 601. A rotating rod 702 is rotatably connected to the bottom of the dust collection chamber 100. A bevel gear 703 and a sprocket 704 are fixedly connected to the outer side of the rotating rod 702, respectively. The bevel gear 703 meshes with the bevel gear 701. When the rotating rod 601 rotates, it drives the bevel gear 701 fixedly connected to it to rotate. The rotating bevel gear 701 drives the bevel gear 703 meshing with it to rotate, so that the bevel gear 703 drives the rotating rod 702 fixedly connected to it to rotate. The rotating rod 702 fixedly connected to it then drives the sprocket 704 fixedly connected to it to rotate.

[0028] A chain 705 is mounted on the outer side of sprocket 1 704. A fixing plate 706 is fixedly connected to the side of the dust collection chamber 100. A rotating rod 707 is rotatably connected to the top of the fixing plate 706. A sprocket 708 is fixedly connected to the outer side of the rotating rod 707. The end of the chain 705 away from sprocket 1 704 is mounted on the outer side of sprocket 2 708. When sprocket 1 704 rotates, it cooperates with the chain 705 mounted on the outer side of sprocket 1 704, causing sprocket 2 708, which is driven by sprocket 1 704 through chain 705, to rotate. The rotating sprocket 2 708 can then drive the rotating rod 707, which is fixedly connected to it, to rotate.

[0029] A reciprocating screw 709 is fixedly connected to the side of the rotating rod 707. A conveying block 710 equipped with a pump is threadedly connected to the outer side of the reciprocating screw 709. The conveying block 710 is located at the top of the fixed plate 706, and the conveying block 710 and the fixed plate 706 are in a sliding connection state. When the rotating rod 707 rotates, it drives the reciprocating screw 709 fixedly connected to it to rotate. The conveying block 710, which is threadedly assembled to the outer side of the reciprocating screw 709, is simultaneously restricted by the fixed plate 706, which is slidably connected to it, so that the conveying block 710 reciprocates in the horizontal direction during the rotation of the reciprocating screw 709.

[0030] A suction hose 715 is installed between the conveying block 710 and the dust inlet 200. A pipe connector 711 is rotatably connected to the top of the conveying block 710. A suction head 712 is installed on the top of the pipe connector 711. A gear 713 is fixedly connected to the side of the pipe connector 711. A rack 714 is fixedly connected to the top of the fixing plate 706. When the conveying block 710 moves to the right side of the reciprocating screw 709, the gear 713 is immediately restricted by the rack 714 located there, causing the gear 713 to rotate synchronously during the movement. The rotating gear 713 can drive the pipe connector 711, which is fixedly connected to it, to rotate. This causes the pipe connector 711 to drive the suction head 712 mounted on its top to rotate at a certain angle, thereby increasing the suction range of the suction head 712 and improving the dust removal efficiency of the device.

[0031] In practical use, when the rotating rod 601 rotates, it drives the bevel gear 701 fixedly connected to it to rotate. The rotating bevel gear 701 drives the bevel gear 703 meshing with it to rotate, which in turn drives the rotating rod 702 fixedly connected to it to rotate. The rotating rod 702 then drives the sprocket 704 fixedly connected to it to rotate. The chain 705 mounted on the outside of the sprocket 704 causes the sprocket 708, which is connected to the sprocket 704 via the chain 705, to rotate. The rotating sprocket 708 then drives the rotating rod 707 fixedly connected to it to rotate, which in turn drives the reciprocating screw 709 fixedly connected to it to rotate. Meanwhile, the conveying block 710, threaded onto the outside of the reciprocating screw 709, is simultaneously slidably connected to the fixing plate 7. The restriction of 06 causes the conveying block 710 to reciprocate horizontally during the rotation of the reciprocating screw 709. The conveying block 710 in the reciprocating state can drive the pipe connector 711, the extraction head 712 and the gear 713 located on it to reciprocate together. When the conveying block 710 moves to the right side of the reciprocating screw 709, the gear 713 is immediately restricted by the rack 714 located there, so that the gear 713 rotates synchronously during the movement. The rotating gear 713 can drive the pipe connector 711 fixedly connected to it to rotate, so that the pipe connector 711 drives the extraction head 712 mounted on it to rotate at a certain angle. The dust in the production workshop is input into the dust collection chamber 100 through the extraction head 712, pipe connector 711, conveying block 710, extraction hose 715 and dust inlet 200.

[0032] Example 3, please refer to Figures 5-8 Based on Embodiments 1 and 2, a dust scraping assembly 800 is installed inside the dust collection chamber 100. The dust scraping assembly 800 includes a transmission rod 801 fixed to the side of the conveying block 710, and a rack 802 is fixedly connected to the side of the transmission rod 801. When the conveying block 710 moves to the left, it can drive the transmission rod 801 fixedly connected to it to move synchronously. The transmission rod 801 in the moving state can drive the rack 802 fixedly connected to it to move.

[0033] A rotating rod 803 is rotatably connected to the side of the dust collection chamber 100. Gears 804 and 805 are fixedly connected to the outer side of the rotating rod 803. When the dust scraping assembly 800 is in operation, gear 804 can mesh with rack 802. When rack 802 moves to gear 804, rack 802 drives gear 804 to rotate clockwise. Gear 804, in turn, drives the rotating rod 803 to rotate, which in turn drives gear 805 to rotate.

[0034] A fixed block 806 is fixedly connected to the top of the dust collection chamber 100. A moving rod 808 is connected to the bottom of the fixed block 806 via a spring 807. A toothed rack 809 and a scraper 810 are fixedly connected to the bottom of the moving rod 808. The toothed rack 809 meshes with a gear 805. The scraper 810 is located on the side of the fixed rod 606 and is slidably connected to the fixed rod 606. When the gear 805 rotates, it drives the toothed rack 809 to move upward, causing the toothed rack 809 to move the moving rod 808. At this time, the moving rod 808 compresses the spring 807 and moves closer to the fixed block 806, causing the moving rod 808 to move the scraper 810 upward together. When the conveyor block 710 is reset, the scraper plate 810 can be reset. The scraper plate 810, which is in a reciprocating state, can scrape off the higher parts of the inner wall of the dust removal chamber 100, removing dust that may remain there because it is not covered by the dust removal liquid.

[0035] In specific use, the above-mentioned equipment shall be used as follows: Figure 7 and Figure 8As shown, during the movement of the conveyor block 710 to the left, it drives the transmission rod 801, which is fixedly connected to it, to move synchronously. The moving transmission rod 801 drives the gear 802, which is fixedly connected to it, to move. When the gear 802 moves to the gear 804, it drives the gear 804, which is meshing with it, to rotate clockwise. The rotating gear 804 then drives the rotating rod 803, which is fixedly connected to it, to rotate. This causes the rotating rod 803 to drive the gear 805, which is fixedly connected to it, to rotate. Wheel 4 805 can drive the gear 3 809 meshing with it to move upward, so that the gear 3 809 drives the moving rod 808 fixedly connected to it to move. At this time, the moving rod 808 compresses the spring 807 and moves closer to the fixed block 806, so that the moving rod 808 drives the scraper 810 fixedly connected to it to move upward together. When the conveying block 710 is reset, the scraper 810 can be reset. The scraper 810 in the reciprocating state can scrape the higher part of the inner wall of the dust removal chamber 100, scraping off the dust that may remain there because it is not covered by the dust removal liquid.
