Description

Technical Field

[0001] The present invention relates to the technical field of automotive part processing, and specifically to a high-pressure spray cleaning device for automotive parts based on atomization suppression. Background Art

[0002] During the production and processing of automotive parts, the surfaces of the parts are usually affected by various pollutants. These pollutants come from multiple aspects such as raw materials, processing techniques, tools, and the environment. For example, when parts are subjected to mechanical processing such as milling, turning, and grinding, these traditional processing methods usually generate pollutants such as metal chips, grease, coolant, and abrasives. The increase in temperature and friction during the processing process can cause the decomposition of lubricating oil, thereby generating chemical substances that may contaminate the surface. If these pollutants are not effectively cleaned, it will affect the quality of the parts and reduce the effects of subsequent processing (such as painting, assembly, welding, etc.). Therefore, it is necessary to clean the parts during the processing process.

[0003] At the present stage, an automatic high-pressure cleaning production line is often used to clean parts. By using high-pressure water flow to impact the surface of the parts, the attached pollutants can be cleaned. During the high-pressure spray cleaning process, the generated water mist will carry pollutants such as cleaning agents, degreasing agents, or oil stains and metal debris on the surface of the parts, forming aerosol pollutants. If the equipment has insufficient sealing or an imperfect exhaust system, these pollutants will diffuse into the workshop or the surrounding environment along with the water mist, causing air pollution. The fine water mist particles can remain suspended in the air for a long time, resulting in the secondary settlement of pollutants such as dust and oil mist in the workshop, affecting the cleanliness of the working environment. Moreover, the mixed aerosol is also likely to adhere to the inner wall of the equipment, reducing the cleanliness inside the equipment. During the cleaning process, the water flow splashing may transfer the pollutants on the inner wall to the surface of the parts again, reducing the cleaning effect. Therefore, a high-pressure spray cleaning device for automotive parts based on atomization suppression is proposed to solve the above problems. Summary of the Invention

[0004] To solve the above technical problems, a high-pressure spray cleaning device for automotive parts based on atomization suppression is provided.

[0015] The beneficial effects of the present invention compared with the prior art are as follows: 1. The present invention is provided with two groups of light curtain induction components. The parts are driven by the conveyor belt to move towards the light curtain induction components. The parts first block the laser emitted by the first group of light curtain induction components, and when the parts continue to move, they will block the laser emitted by the second group of light curtain induction components. The running speed of the conveyor belt can be obtained through the time difference of the two groups of light curtain induction components receiving the laser and the distance between the two groups of light curtain induction components. At the same time, the length of the parts can be obtained through the total time of the parts blocking the single-group laser. The spraying and cleaning time can be set according to the length of the parts. The opening and closing of the upper spray head and the lower spray head can be controlled respectively through the first electromagnetic valve and the second electromagnetic valve. When there are no parts to be cleaned in the spraying and cleaning tank, the water spraying stops. This can not only reduce the water mist generated by the high-pressure water flow impacting the conveyor belt but also save more water resources. Reducing the water mist in the spraying and cleaning tank also reduces the risk of pollutants diffusing into the workshop or the surrounding environment along with the water mist. At the same time, the height of the parts can be obtained through the maximum number of lasers blocked by the parts from the light curtain induction components, and the height of the upper spraying assembly can be adjusted through the hydraulic lifting column so that the upper spray head sprays and cleans the parts at an appropriate height, reducing the flying distance of the water flow in the air, thereby limiting the diffusion range of the water mist, reducing the secondary atomization generated by the water flow rebound. After reducing the height, the water flow acts more concentratedly on the target surface, reducing the water mist formed by splashing.

[0016] 2. The present invention is provided with three air curtain enclosure components. The air curtain enclosure components are installed inside the spraying and cleaning tank. High-pressure gas blows downward through the air curtain enclosure components to form an air curtain barrier, which can block the diffusion of water mist to the outside of the spraying and cleaning tank. After the water mist contacts the air curtain, it will be brought to the lower part and liquefy after contacting the conveyor belt and finally flow into the waste water collection tank together with the waste water for collection.

[0017] 3. The present invention is provided with a negative pressure collection device and a wastewater filtration device. The water mist in the spray cleaning tank enters the negative pressure collection device through the water mist collection pipe due to the negative pressure in the negative pressure collection device. After being blocked and guided by the first baffle, the first wire mesh, the second baffle, the second wire mesh and the third baffle, it liquefies and flows into the collection bin for collection. The waste liquid in the collection bin and the wastewater collection tank is sent to the wastewater filtration device by a water pump. The debris and other pollutants are filtered by the multi-stage filter screen in the wastewater filtration device, and the oil in the waste liquid is separated by the oil-water separation component. The treated water can be recycled, saving water resources. Brief Description of the Drawings

[0020] For example, certain terms are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as the criterion for distinction. The term "comprising" mentioned throughout the specification and claims is an open-ended term, so it should be interpreted as "comprising but not limited to". The subsequent description in the specification is the preferred implementation manner for implementing the present application, but the description is for the purpose of explaining the general principles of the present application and is not used to limit the scope of the present application.

[0021] Such as Figures 1 - 4As shown in the figure, a high-pressure spray cleaning device for automotive parts based on atomization suppression includes: a device box 1, a spray cleaning box 2, a negative pressure collection device 3, a waste water filtration device 4, and a pressurization device 5. A conveyor belt 11 is installed in the middle of the device box 1, and the conveyor belt 11 is used to convey the parts to be cleaned. Two groups of light curtain induction components 13 are installed at the upper end of the device box 1. The two groups of light curtain induction components 13 are arranged on both sides of the conveyor belt 11. The light curtain induction components 13 measure the size of the parts by the time when the parts block the laser emitted by them. The laser emission end of the light curtain induction components 13 emits a number of parallel laser beams, and the laser receiving end of the light curtain induction components 13 receives the emitted laser. When the parts are placed on the conveyor belt 11, the conveyor belt 11 drives the parts to move towards the light curtain induction components 13. The parts first block the laser emitted by the first group of light curtain induction components 13, and the laser receiving end of the first group of light curtain induction components 13 cannot receive the laser. The parts continue to move and block the laser emitted by the second group of light curtain induction components 13. The running speed of the conveyor belt 11 can be obtained through the time difference between the two groups of light curtain induction components 13 receiving the laser and the distance between the two groups of light curtain induction components 13. At the same time, the length of the parts can be obtained through the total time of the parts blocking the laser of a single group. The spray cleaning time can be set according to the length of the parts. When there are no parts to be cleaned in the spray cleaning box 2, the water spray is stopped. This can not only reduce the water mist generated by the high-pressure water flow impacting the conveyor belt 11 but also save more water resources. Reducing the water mist in the spray cleaning box 2 also reduces the risk of pollutants diffusing to the workshop or the surrounding environment along with the water mist. At the same time, the height of the parts can be obtained through the maximum number of lasers blocked by the parts from the light curtain induction components 13. By adjusting the appropriate height of the nozzles, the flying distance of the water flow in the air can be reduced, thereby limiting the diffusion range of the water mist. When the water flow impacts the surface of the parts, a higher nozzle will cause the water flow to rebound and generate secondary atomization. After reducing the height, the water flow acts more concentratedly on the target surface, reducing the water mist formed by splashing. The spray cleaning box 2 is installed at the upper end of the device box 1. Water mist buffer boxes 12 for blocking water mist are arranged at both ends of the spray cleaning box 2. A plurality of shielding curtains 121 are installed at the front ends of the water mist buffer boxes 12. Shielding curtains 121 are also arranged on both sides of the spray cleaning box 2.

[0026] As Figure 8 and Figure 9 shown, a first baffle 32 is arranged inside the negative pressure collection device 3. Both ends of the first baffle 32 are fixedly connected to the inner wall of the negative pressure collection device 3 and the surface of the partition plate 35 respectively.

The water treated by the oil-water separation assembly 47 can be recycled to save water resources.

[0028] The principle of the present invention is as follows: the parts are driven to move by the conveyor belt 11, and the parts first block the laser emitted by the first group of light curtain sensor components 13. The laser receiving end of the first group of light curtain sensor components 13 cannot receive the laser, and the parts continue to move to block the laser emitted by the second group of light curtain sensor components 13. The running speed of the conveyor belt 11 can be obtained by the time difference between the two groups of light curtain sensor components 13 receiving the laser and the distance between the two groups of light curtain sensor components 13. At the same time, the length of the parts can be obtained by the total time that the parts block a single group of lasers. The opening and closing of the upper nozzle 212 and the lower nozzle 232 are controlled by the first electromagnetic valve 215 and the second electromagnetic valve 234. During the spray cleaning When there are no parts in the box 2 that need to be cleaned, water spraying is stopped to reduce the water mist generated by the high-pressure water flow impacting the conveyor belt 11, and the risk of pollutants spreading to the workshop or the surrounding environment with the water mist is reduced. The height of the part can be obtained by blocking the maximum number of lasers emitted by the light curtain sensing component 13 by the part. The height of the upper spray component 21 is controlled by the hydraulic lifting column 218, so that the upper nozzle 212 sprays and cleans the parts at an appropriate height, reducing the flight distance of the water flow in the air, thereby limiting the diffusion range of the water mist, and also reducing the situation of secondary atomization caused by the rebound of the water flow. The length and height of the cleaned parts are measured by the light curtain sensing component 13, and the nozzle cleaning is adjusted in a linked manner. The washing time and the height of the upper spray assembly 21 reduce the water mist generated by the impact of the high-pressure water flow. Three wind curtain enclosure assemblies 22 are installed in the spray cleaning box 2. The high-pressure gas is blown downward through the wind curtain enclosure assembly 22 to form a wind curtain barrier to prevent the water mist from diffusing outward. The water mist in the spray cleaning box 2 enters the negative pressure collection device 3 through the water mist collection pipe 31 due to the negative pressure in the negative pressure collection device 3. The water mist is liquefied after passing through the first baffle 32, the first wire mesh 321, the second baffle 33, the second wire mesh 331 and the third baffle 37. The water mist flows into the collection bin 36 for collection. The waste liquid in the collection bin 36 and the wastewater collection box 25 is pumped to the wastewater filter by a water pump. In the device 4, debris and other pollutants are filtered out by the multi-stage filter screen in the wastewater filter device 4, and the grease in the waste liquid is separated by the oil-water separation component 47, and the treated water can be recycled again. In summary, the size of the parts is measured by the light curtain sensing component 13, and the spraying time and the spraying height are adjusted in linkage to achieve the purpose of reducing the generation of water mist. The wind curtain enclosure component 22 blocks the water mist from diffusing to the outside of the spray cleaning box 2. The water mist in the spray cleaning box 2 is recovered by the negative pressure collection device 3, and the generated water mist is collected and processed. The waste liquid from the spray cleaning is recycled after being processed by the wastewater filter device 4, thereby reducing the waste of water resources.
