Description

Technical Field

[0001] This application relates to the technical field of polishing waste collection equipment, and in particular to an automatic polishing waste collection device. Background Technology

[0002] The main purpose of polishing aluminum alloy wheels is to remove surface defects such as burrs, scratches, corrosion spots, sand holes, and air pores from the workpiece surface. At the same time, it further removes the fine unevenness on the workpiece surface, giving it a higher gloss, which not only improves durability but also enhances the appearance quality. The process involves applying polishing paste to the aluminum alloy wheel and using the rotation and friction of the polishing cloth wheel to make the wheel bright and beautiful. As the polishing cloth wheel will wear down over a long period of time, it will produce polishing waste such as aluminum alloy powder, polishing cloth scraps, and polishing paste residue. If these polishing wastes are not disposed of in time, they can cause harm to the human body and cause environmental pollution when released into the atmosphere.

[0003] In the prior art, Chinese Patent No. CN217860362U discloses a plate polishing and grinding device with a recycling function. In this utility model, the polishing waste extraction plate is installed on both sides of the second drive motor in the lower section of the limiting frame. During the polishing process, the polishing waste is collected and discharged into the lower polishing waste collection box and polishing waste removal drawer through the plate polishing and grinding moving groove, polishing waste extraction connection port, polishing waste connecting pipe and polishing waste extraction plate for storage. This can effectively prevent the polishing waste from scattering, allow for long-term polishing, and greatly improve work efficiency.

[0004] However, existing technologies only collect the falling waste using collection structures. However, the polishing process also generates a large amount of flying debris and dust in the air, resulting in a harsh working environment that can harm workers. Furthermore, the polishing waste is directly discharged into the atmosphere, causing environmental pollution. Summary of the Invention

[0005] In order to reduce harm to the human body and avoid environmental pollution, this application provides an automatic collection device for polishing waste.

[0006] This application provides an automatic polishing waste collection device, which adopts the following technical solution:

[0007] An automatic polishing waste collection device includes:

[0008] The fan and the motor that drives the fan are connected by the rotating shaft of the fan and the motor;

[0009] An air collecting pipe is fixedly connected to the air inlet end of the fan;

[0010] The end of the air collecting pipe away from the fan is connected to a smoke extraction pipe; the end of the smoke extraction pipe away from the air collecting pipe is provided with an air collecting hood, the opening of which faces the polishing machine.

[0011] The gas collection hood, the smoke pipe, the gas collection pipe, and the exhaust pipe are connected in sequence.

[0012] A spray pipe is provided on the smoke pipe. The water outlet end of the spray pipe is connected to a nozzle and extends into the smoke pipe. The water inlet end of the spray pipe is connected to a water tank through a water pump.

[0013] A drain pipe is provided on the side of the smoking pipe near the ground to collect falling water, and a water tank is connected to the end of the drain pipe to collect the water from the drain pipe.

[0014] The end of the smoking pipe near the gas collecting hood is higher than the end of the smoking pipe near the gas collecting pipe.

[0015] By adopting the above technical solution, when polishing waste is generated by the polishing machine, the motor drives the fan to operate, and the equipment creates a negative pressure environment. The mixture of polishing waste and air enters the smoke pipe through the gas collection hood. Water is sprayed from the nozzles in the smoke pipe, and the water absorbs the polishing waste in the mixture. The wastewater formed by the spray water and polishing waste falls to the bottom of the inclined smoke pipe. Under the action of gravity, the wastewater flows to the drain pipe and enters the water tank. The purified air enters the gas collection pipe and is discharged into the atmosphere after passing through the fan. This can reduce harm to the human body and avoid environmental pollution.

[0016] Optionally, a section of the smoke extraction pipe located between the nozzle and the gas collection hood is configured as an L-shaped smoke extraction pipe, with the opening at the end of the L-shaped smoke extraction pipe near the nozzle facing the ground.

[0017] By adopting the above technical solution, the gas flow speed is temporarily slowed down due to the obstruction of the side wall of the L-shaped smoke pipe. Some polishing waste falls off under the action of gravity. The slowed gas flow also makes the spraying more comprehensive, which is conducive to the separation of polishing waste and improves the processing efficiency.

[0018] Optionally, a filter screen is provided between the smoke extraction pipe and the gas collection pipe, and the filter screen is positioned close to the drain pipe.

[0019] By adopting the above technical solution, residual polishing waste and other harmful substances in the sprayed gas can be further filtered, reducing harmful substances in the discharged gas, improving the quality of the discharged gas, and protecting the environment; the filter screen is set close to the drain pipe, so that the polishing waste on the filter screen can fall directly into the drain pipe, avoiding secondary cleaning.

[0020] Optionally, a vibration mechanism is also provided on the filter screen; the vibration mechanism includes a vibrator disposed on the filter screen and a controller disposed on the outer wall of the air collection pipe, the vibrator and the controller being interconnected through a connecting pipe.

[0021] By adopting the above technical solution, the polishing waste on the filter screen can be shaken off, the filter screen can be cleaned in time, and the air filtration quality can be guaranteed.

[0022] Optionally, the gas collecting pipe is vertically arranged above the drain pipe and communicates with the smoke extraction pipe.

[0023] By adopting the above technical solution, when the gas containing polishing waste in the smoke extraction pipe flows into the gas collection pipe, the large particles of polishing waste will fall directly into the drain pipe under the action of gravity and be discharged into the water tank below, thereby improving the air purification efficiency; it can also prevent wastewater from flowing into the gas collection pipe, affecting the collection of polishing waste, or even damaging the fan.

[0024] Optionally, the water inlet end of the spray pipe is placed inside the water tank.

[0025] By adopting the above technical solution, the water inlet end of the spray pipe is placed directly in the water tank, and the port of the spray pipe is located in the upper middle part of the water body, which avoids drawing water containing polishing waste, promotes water recycling, saves water resources, and eliminates the need for a separate water tank, thus reducing cost expenditures.

[0026] Optionally, a funnel is provided inside the drain pipe, and the outer wall of the top of the funnel is tightly connected to the inner wall of the drain pipe; a filter screen is provided between the inner wall of the drain pipe and the outer wall of the funnel.

[0027] By adopting the above technical solution, a water storage space can be formed between the drain pipe, funnel, and filter screen. The water in this storage space is filtered and impurities are removed, and it does not contain large particles. The water inlet of the spray pipe is connected to the water storage space, which can avoid clogging of the spray pipe and better realize the recycling of water.

[0028] Optionally, a conveyor belt with a scraper is provided on the inner wall of the water tank, the scraper being vertically arranged on the surface of the conveyor belt; the conveyor belt is parallel to the inner wall of the water tank; one end of the conveyor belt is located at the bottom of the water tank, and the other end of the conveyor belt extends out from inside the water tank.

[0029] By adopting the above technical solution, the conveyor belt drives the scraper to rotate, which carries the polishing waste that has settled at the bottom of the water tank out of the water tank, thus realizing the recycling of polishing waste.

[0030] Optionally, a guide channel is provided below one end of the conveyor belt that extends out of the water tank. The guide channel is inclined and fixedly connected to the edge of the water tank. A collection vehicle is parked below the guide channel.

[0031] By adopting the above technical solution, the polishing waste transported to the extended end of the conveyor belt falls into the guide trough and is discharged into the collection vehicle below along the guide trough; the guide trough is set at an angle to prevent the polishing waste from falling directly and splashing everywhere, so that the polishing waste flows into the collection vehicle in a fixed direction.

[0032] Optionally, the scraper has an arc-shaped structure and is provided with filter holes.

[0033] By adopting the above technical solution, the scraper is set with an arc-shaped structure, which can better scrape and transport polishing waste. The scraper is provided with water filter holes, which can make the scraped water flow back into the water tank, preventing a large amount of water from entering the collection vehicle. It can also prevent water from washing the scraped polishing waste back into the water tank, which is conducive to improving the recycling efficiency of polishing waste and saving water.

[0034] Optionally, the sidewalls of the water tank are inclined.

[0035] By adopting the above technical solution, it is convenient to install the conveyor belt and also convenient for the scraper to scrape out the polishing waste that has settled at the bottom of the water tank, which is conducive to the recycling and utilization of waste.

[0036] Optionally, an exhaust pipe is fixedly connected to the exhaust end of the fan.

[0037] By adopting the above technical solution, the direction of the gas discharged by the fan can be controlled.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. Water is sprayed out through the nozzles inside the smoke extraction pipe. The water absorbs the polishing waste in the mixed gas. The wastewater formed by the spray water and polishing waste falls to the bottom of the inclined smoke extraction pipe. Under the action of gravity, the wastewater flows to the drain pipe and enters the water tank. The purified air enters the gas collection pipe, passes through the fan, and then enters the exhaust pipe to be discharged into the atmosphere. This can reduce harm to the human body and avoid environmental pollution.

[0040] 2. By setting up a funnel, a water storage space is formed between the drain pipe, the funnel, and the filter screen. The water in this storage space has been filtered and impurities removed, and does not contain large particles. The water inlet of the spray pipe is connected to the water storage space, which can avoid clogging of the spray pipe and better realize the recycling of water.

[0041] 3. The conveyor belt drives the scraper to rotate, which carries the polishing waste that has settled at the bottom of the water tank out of the water tank, thus realizing the recycling and utilization of polishing waste. Attached Figure Description

[0044] The following combination Figure 1 This application will be described in further detail.

[0045] This embodiment discloses an automatic collection device for polishing waste.

[0046] Reference Figure 1 An automatic polishing waste collection device includes: a blower 1 and a motor 2 that drives the blower 1 to rotate; the impeller of the blower 1 is directly connected to the rotating shaft of the motor 2; an air collecting pipe 3 is fixedly connected to the air inlet end of the blower 1; a smoke extraction pipe 4 is fixedly connected to the end of the air collecting pipe 3 away from the blower 1; and an exhaust pipe 6 is fixedly connected to the exhaust end of the blower 1, and the exhaust pipe 6 is installed vertically; an air collecting hood 7 is provided at the end of the smoke extraction pipe 4 away from the air collecting pipe 3, with the opening of the air collecting hood 7 facing the polishing machine, for timely collection of waste dust generated by the polishing machine; the air collecting hood 7, the smoke extraction pipe 4, the air collecting pipe 3, and the exhaust pipe 6 are connected in sequence.

[0047] A spray pipe 8 is provided on the outer wall of the smoke pipe 4. The water outlet end of the spray pipe 8 is connected to a nozzle 9 and extends into the smoke pipe 4. The water inlet end of the spray pipe 8 is connected to a water source through a water pump. The water pump can pump water from a lower position into the smoke pipe 4, which can also improve the spraying effect and facilitate the combination of polishing waste with water.

[0048] A drain pipe 10 is provided on the side of the smoke pipe 4 closest to the ground to collect falling water. Wastewater generated by the combination of polishing waste and water flows along the side of the smoke pipe 4 closest to the ground under the action of gravity. The drain pipe 10 is located on the side of the smoke pipe 4 closest to the ground, which is conducive to the direct discharge of wastewater into the drain pipe 10. A water tank 11 is connected to the end of the drain pipe 10 to collect the water in the drain pipe 10. The end of the smoke pipe 4 closest to the gas collection hood 7 is higher than the end of the smoke pipe 4 closest to the gas collection pipe 3. The inclined structure is conducive to the flow of wastewater from top to bottom into the drain pipe 10.

[0049] The section of the smoke extraction pipe 4 located between the nozzle 9 and the air collection hood 7 is set as an L-shaped smoke extraction pipe 5. The opening of the L-shaped smoke extraction pipe 5 near the nozzle 9 faces the ground. When the polishing waste sucked into the smoke extraction pipe 4 passes through the bend of the L-shaped smoke extraction pipe 5, it not only collides with the inner wall of the L-shaped smoke extraction pipe 5, but also the flow speed of the polishing waste is temporarily slowed down. This can effectively combine with the spray water from the nozzle 9 and accelerate the falling of the polishing waste.

[0050] To further purify the flowing gas after spraying, a filter screen 12 is installed between the smoke pipe 4 and the gas collecting pipe 3 to improve the quality of the discharged gas. The filter screen 12 is installed close to the drain pipe 10 so that the polishing waste on the filter screen 12 can fall directly into the drain pipe 10, avoiding secondary cleaning. In this embodiment, the gas collecting pipe 3 is vertically installed above the drain pipe 10 and connected to the smoke pipe 4. The filter screen 12 is installed at the connection between the smoke pipe 4 and the gas collecting pipe 3, located directly above the drain pipe 10.

[0051] A vibration mechanism 13 is provided on the filter screen 12, including a vibrator 131 provided on the filter screen 12 and a controller 132 provided on the outer wall of the air collection pipe 3 for controlling the switching of the vibrator 131. The vibrator 131 and the controller 132 are connected to each other through a connecting pipe 133. In this embodiment, the vibration structure uses a pneumatic vibrator 131.

[0052] To achieve the recycling of wastewater containing polishing waste in the water tank 11, a funnel 14 is installed inside the drain pipe 10, with the outer wall of the top of the funnel 14 tightly connected to the inner wall of the drain pipe 10. A filter screen 15 is installed between the inner wall of the drain pipe 10 and the outer wall of the funnel 14, forming a water storage space 16 between the drain pipe 10, the funnel 14, and the filter screen 15. The water in the water storage space 16 is filtered and free of large particles. The inlet end of the spray pipe 8 is then connected to the water storage space 16, which enables water recycling and avoids clogging of the spray pipe 8.

[0053] The polishing waste deposited at the bottom of the water tank 11 needs to be cleaned regularly. A conveyor belt 17 with a scraper 18 is provided on the inner side wall of the water tank 11. The scraper 18 is vertically arranged on the surface of the conveyor belt 17. The conveyor belt 17 is parallel to the inner side wall of the water tank 11. One end of the conveyor belt 17 is located at the bottom of the water tank 11, and the other end of the conveyor belt 17 extends out of the water tank 11. The side wall of the water tank 11 is inclined.

[0054] A guide trough 19 is provided below one end of the conveyor belt 17 that extends from the water tank 11. The guide trough 19 is inclined and fixedly connected to the edge of the water tank 11. A collection vehicle 20 is parked below the guide trough 19, and polishing waste flows into the collection vehicle 20 in a fixed direction.

[0055] The scraper 18 is designed with an arc shape and has filter holes. The filter holes are small and are used to drain water, recover solid colloidal substances in the water, and allow the scraped water to flow back into the water tank 11.

[0056] The implementation principle of this application embodiment is as follows: When polishing waste is generated by the polishing machine, the gas collection hood 7 is first oriented towards the polishing machine or the workshop where the polishing machine is located. The motor 2 drives the fan 1 to run, and the equipment forms a negative pressure environment. The mixture of polishing waste and air enters the smoke pipe 4 through the gas collection hood 7. When passing through the bend of the L-shaped smoke pipe 5, it collides with the inner wall of the L-shaped smoke pipe 5, and some polishing waste falls off. Moreover, the flow speed of the polishing waste will be temporarily slowed down. At this time, it will pass through the nozzle 9 in the smoke pipe 4, and the nozzle 9 sprays water. The water absorbs the polishing waste in the mixture of gas. The wastewater formed by the spray water and polishing waste falls to the bottom of the inclined smoke pipe 4. Under the action of gravity, the wastewater flows to the drain pipe 10 and enters the water tank 11. The purified air is purified again by the filter screen 12 and then enters the gas collection pipe 3. After passing through the fan 1, it is discharged into the atmosphere, which can reduce the harm to the human body and avoid environmental pollution.

[0057] Wastewater entering the drain pipe 10 flows through the funnel 14 to the bottom of the water tank 11. Then, some of the wastewater is filtered by the filter screen 15 and enters the water storage space 16 between the drain pipe 10, the funnel 14, and the filter screen 15. The inlet end of the spray pipe 8 is connected to the water storage space 16. The filtered polishing waste is deposited at the bottom of the water tank 11. The conveyor belt 17 rotates, driving the scraper 18 to rotate and carry the polishing waste settled at the bottom of the water tank 11 out of the water tank 11 and into the collection vehicle 20, thus realizing the recycling of polishing waste.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
