Description

Technical Field

[0001] This utility model relates to the technical field of reducing dust pollution from polishing machines, and in particular to an exhaust device for polishing machines that reduces dust pollution. Background Technology

[0002] A polishing machine is a mechanical device used to polish the surface of an object. Its core function is to remove rough parts, scratches, and oxide layers from the surface of a material through physical friction, grinding, and chemical action, thereby obtaining a smooth, flat, and high-gloss surface effect.

[0003] The dust, harmful gases, and heat generated during the polishing process of a polishing machine have a negative impact on the working environment, the health of operators, and the lifespan of the equipment. Factories need to control the emission of pollutants generated during polishing to avoid dust explosions and toxic gas hazards. Therefore, a polishing machine exhaust device is needed.

[0004] Currently, polishing machine exhaust systems on the market generally consist of a fan, a dust collection hood, and a dust collection container. The fan generates negative pressure airflow, driving pollutants through pipes and filters. The dust collection hood is close to the polishing work point, sucking in dust and debris through negative pressure and collecting the filtered dust for centralized treatment. Since the dust is discharged through the fan, it causes secondary pollution to the outside world. To solve the above problem, filters are usually added to separate dust and gas, and clean air is discharged after purification. However, in actual use, because the inside of the exhaust system and the filter are inconvenient to clean, dust remains inside the device, reducing the ventilation volume and exhaust effect, and failing to meet the user's needs. Utility Model Content

The second motor drives the threaded rod to rotate, causing the slider to move the roller brush. Then the roller brush drives the transmission wheel to move. Due to the meshing relationship between the transmission wheel and the rack, the transmission wheel in turn drives the roller brush to rotate, so that the roller brush can sweep the dust into the dust discharge box. At the same time, the water pump can draw water from the water tank and re-inject it into the tank to achieve recycling. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a polishing machine exhaust device for reducing dust pollution, comprising a tank 1. A first filter 3 is fixedly connected inside the tank 1 for filtering dust. A first motor 4 is fixedly connected to the upper right side of the tank 1. The output end of the first motor 4 passes through the tank 1 and is fixedly connected to a drive bevel gear 5, which drives the drive bevel gear 5 to rotate. A water inlet pipe 6 is connected to the upper left side of the outer wall of the tank 1 for injecting water into the tank 1. The water inlet pipe 6 passes through the tank 1, and a connecting sleeve 7 is fixedly connected to one end of the water inlet pipe 6. The connecting sleeve 7 is rotatably connected to the connecting pipe 8. The middle of the outer wall of the connecting pipe 8 is fixedly connected to the driven bevel gear 9. The driving bevel gear 5 meshes with the driven bevel gear 9. The driving bevel gear 5 drives the driven bevel gear 9 to rotate. The bottom of the connecting pipe 8 passes through the first filter screen 3. The lower middle part of the outer wall of the connecting pipe 8 is fixedly connected to the scraper 10, which is used to scrape the dust on the inner wall of the tank 1. The bottom end of the connecting pipe 8 is connected to the washing pipe 11. The left and right sides, front and rear ends of the washing pipe 11 are equidistantly provided with water spray nozzles 12. The lower middle part of the outer wall of the tank 1 is fixedly connected to the support frame 21.

[0033] Specifically, dust is drawn into the tank 1 through the suction pipe 15, then filtered by the first filter 3, and the purified air is discharged, while the dust is trapped inside the tank 1. When it is necessary to clean the tank 1 and the first filter 3, the first motor 4 is started to drive the active bevel gear 5, which in turn causes the driven bevel gear 9 to rotate. The rotation of the driven bevel gear 9 drives the connecting pipe 8, which in turn causes the scraper 10 and the washing pipe 11 to rotate. At this time, the water inlet pipe 6 injects water into the washing pipe 11 through the connecting pipe 8. As the scraper 10 and the washing pipe 11 rotate continuously, the water flow cleans the inner wall of the tank 1 and the first filter 3, ensuring that the first filter 3 will not be blocked, thereby preventing dust from remaining inside the tank 1. The support frame 21 is used to support the entire tank 1.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The separation mechanism 2 includes a water tank 201, which is located at the bottom of the tank body 1. A dust collection box 202 is located at the right end of the water tank 201 to collect the discharged dust. A second filter screen 212 is fixedly connected inside the water tank 201 to filter and separate the dust from the water. A suction pipe 204 is connected to the lower left end of the water tank 201. A water pump 203 is fixedly connected to the lower left end of the tank body 1 to realize water circulation. The adjacent ends of the water inlet pipe 6 and the suction pipe 204 are both connected to the water pump 203. The upper middle part of the inner wall of the water tank 201 has mounting grooves 211 on both the front and rear sides. A threaded rod 206 is rotatably connected inside the front mounting groove 211. A slider is threadedly connected to the left side of the outer wall of the threaded rod 206. 207, the slider 207 can move along the threaded rod 206, the upper middle part of the left front side of the water tank 201 is fixedly connected to the second motor 205, the output end of the second motor 205 passes through the water tank 201 and is fixedly connected to the left end of the threaded rod 206, the second motor 205 drives the threaded rod 206 to rotate, the bottom of the rear mounting groove 211 is fixedly connected to the rack 209, the rear end of the slider 207 is rotatably connected to the roller brush 208, the rear end of the roller brush 208 is fixedly connected to the transmission wheel 210, the transmission wheel 210 is meshed with the rack 209, the front end of the front mounting groove 211 is provided with a sliding groove 19 for limiting the slider 207, the front end of the slider 207 is slidably connected inside the sliding groove 19;

[0035] Specifically, after the dust is discharged through the dust discharge pipe 16 along with the water flow, the second filter 212 can re-filter the water flow and return it to the water tank 201. The accumulated dust will be driven by the start of the second motor 205 to rotate the threaded rod 206, thereby causing the slider 207 to move under the restriction of the slide groove 19. The movement of the slider 207 will drive the roller brush 208. Due to the meshing of the transmission wheel 210 at the other end of the roller brush 208 with the rack 209, the roller brush 208 will rotate during the movement, effectively sweeping the dust to the dust discharge box 202. The water in the water tank 201 is drawn by the water pump 203 and re-enters the water inlet pipe 6 through the water suction pipe 204, completing the water recycling.

[0036] Reference Figure 1 and Figure 2 The top of the tank 1 is connected to an exhaust pipe 14, and the top of the exhaust pipe 14 is fixedly connected to a centrifugal fan 13 for generating negative pressure airflow. The lower right part of the tank 1 is connected to a dust suction pipe 15, and the bottom of the tank 1 is connected to a dust discharge pipe 16 for discharging dust from the tank 1.

[0037] Specifically, the centrifugal fan 13 creates a negative pressure airflow inside the tank 1 through the exhaust pipe 14, and then the dust is sucked up through the dust suction pipe 15. The dust discharge pipe 16 can then discharge the dust from the tank 1.

[0038] Reference Figure 1 , Figure 2 and Figure 3 Gaskets 17 are fixedly connected to the front and rear ends of the right side of the dust collection box 202. Screws 18 are fixedly connected to one side of each of the two gaskets 17. The adjacent ends of the two screws 18 pass through the gaskets 17 and are threadedly connected to the water tank 201. A controller 20 is fixedly connected to the lower front part of the tank body 1. The controller 20 is electrically connected to the first motor 4 and the second motor 205 respectively.

[0039] Specifically, screw 18 is used to connect dust collection box 202 to water tank 201, which facilitates the disassembly of dust collection box 202. Gasket 17 can protect the connection part. Controller 20 can control the operating status of first motor 4 and second motor 205.

[0040] Working principle: Dust is sucked into the tank 1 through the suction pipe 15 and filtered by the first filter screen 3. The purified air is discharged, leaving the dust inside the tank 1. When it is necessary to clean the tank 1 and the first filter screen 3, the first motor 4 is started to drive the active bevel gear 5, which in turn drives the driven bevel gear 9 to rotate. The driven bevel gear 9 then drives the connecting pipe 8 to rotate. The connecting pipe 8 then drives the scraper 10 and the washing pipe 11 to rotate. At this time, the water inlet pipe 6 injects water into the washing pipe 11 through the connecting pipe 8. As the scraper 10 and the washing pipe 11 rotate continuously, the water flow cleans the inner wall of the tank 1 and the first filter screen 3, preventing the first filter screen 3 from clogging and dust from remaining inside the tank 1.

[0041] Furthermore, after the dust is discharged through the dust discharge pipe 16 with the water flow, the water can be re-filtered through the second filter screen 212 and enter the water tank 201. The accumulated dust will be driven by the second motor 205 to rotate the threaded rod 206, thereby driving the slider 207 to move under the limit of the slide groove 19. When the slider 207 moves, it drives the roller brush 208 to move. Due to the meshing relationship between the transmission wheel 210 connected to the other end of the roller brush 208 and the rack 209, the roller brush 208 will rotate with the transmission wheel 210 while moving, thereby cleaning the dust into the dust discharge box 202. The water in the water tank 201 is drawn by the water pump 203 and enters the water inlet pipe 6 through the water suction pipe 204 to achieve recycling.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
