Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to an environmentally friendly automobile spraying equipment. Background Art

[0002] Automobile spraying equipment is a special equipment used to paint the surface of automobiles. It occupies a very important position in automobile manufacturing, ensuring the appearance quality and anti-corrosion performance of the vehicle. The following is a brief introduction to the main types and functions of automobile spraying equipment: Manual spraying equipment: The spray gun is manually operated, suitable for small-scale production or repair work. Automatic spraying equipment: Spraying is completed by a manipulator or an automatic sprayer, widely used in large-scale production, with high efficiency and consistency. Electrostatic spraying equipment: The paint is evenly sprayed on the surface of the car using the principle of electrostatic adsorption. It is suitable for metal surface spraying, with high paint utilization and uniform paint film. Air spraying equipment: The paint is atomized by compressed air, suitable for high-precision painting. High-pressure airless spraying equipment: The paint is directly atomized by high pressure, suitable for high-viscosity paint, and has high efficiency.

[0003] As a key link in industrial manufacturing, the pollution problems caused by spraying operations have attracted widespread attention, especially in the fields of automobiles, home appliances, construction machinery, etc. Its pollution is mainly reflected in the following aspects: Sources of pollution from spraying operations, volatile organic compound (VOC) emissions: Solvent-based paints used in the spraying process will volatilize a large amount of VOCs, which are harmful to the human body and will form photochemical smog, aggravating air pollution. In many countries, VOC emissions have become the main regulatory object of the coating industry. Paint mist particle diffusion: Spraying operations will produce a large amount of paint mist particles, which not only waste paint, but also pollute the workshop environment and atmosphere. Without effective filtering and recovery devices, these particles will have adverse effects on the environment and workers' health. Solid waste and wastewater: Unused paint deposits generated during the spraying process and wastewater from cleaning equipment contain a large amount of chemicals, posing a threat to soil and water bodies. High energy consumption and large carbon emissions: Traditional spraying processes require high-temperature drying equipment, which consumes huge energy and indirectly leads to more greenhouse gas emissions.

[0004] Governments around the world are increasingly stringent in their requirements for industrial pollution control. For example, Europe has introduced the Industrial Emissions Directive, which requires the control of VOC emissions; China has also issued the Air Pollution Prevention and Control Action Plan, which requires the coating industry to reduce volatile pollutant emissions. Spraying equipment that does not meet the standards may face suspension of production for rectification or fines, and companies are forced to seek more environmentally friendly solutions. Consumers' increasing preference for green and environmentally friendly products has forced manufacturers to adopt more environmentally friendly processes and equipment in the production process. More and more companies have realized that environmental friendliness is part of their brand competitiveness and are actively upgrading their spraying equipment to reduce environmental load. The high pollution and high energy consumption of traditional spraying directly affect the operating costs of companies. Environmentally friendly spraying equipment can effectively improve the utilization rate of coatings and energy-saving effects, saving costs for companies. Policy subsidies and support: The government's support for environmental protection equipment, including tax exemptions and financial subsidies, encourages companies to upgrade their equipment.

[0005] In the process of automobile spraying, especially when spraying precision parts and difficult parts, or later paint repair spraying, the demand and necessity of manual spraying still exists, but the existing spraying equipment is not enough to protect against manual spraying. Operators are often directly or indirectly exposed to a large amount of harmful substances, and the splashing paint generated during the spraying process can easily cause pollution. The demand for environmentally friendly spraying needs to be urgently addressed.

[0006] In view of the above situation, in order to overcome the above technical problems, the present invention designs an environmentally friendly automobile spraying equipment to solve the above technical problems. Summary of the invention

[0007] The technical purpose to be achieved by the present invention is to design an environmentally friendly automobile spraying equipment, adopt a fully enclosed environment during the spraying process, reduce environmental pollution and protect the safety of workers, absorb the paint splashes generated by the spraying through a water curtain and air suction, and realize the repeated recycling of water resources.

[0008] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0009] An environmentally friendly automobile spraying equipment comprises a bracket, a spraying mechanism, an isolation component and an exhaust duct, and is designed to reduce pollution to the environment during the spraying process, improve resource utilization, and provide a safer working environment for operators.

[0010] The support of the equipment is firmly installed on the ground, supporting the operation of the entire spraying equipment. The spraying mechanism is installed above the support and is the core part of the equipment. In the spraying mechanism, the water curtain assembly intercepts and diverts the water flow on the water curtain slope to form a continuous water curtain. The water curtain can not only effectively absorb and intercept the paint particles splashed during the spraying process, but also greatly reduce the possibility of them escaping into the air. In this way, the exhaust gas and solid pollutants generated during the spraying process can be significantly reduced.

[0011] The water that flows back from the water curtain assembly will flow to the return assembly in the equipment. After preliminary filtration by the filter assembly, the water can be recycled again to form a closed water resource utilization circulation system. The filtered water is used again to form the water curtain, which can not only absorb more splashed paint, but also maximize the use of water resources. This design significantly reduces water consumption, meets environmental protection requirements, and reduces operating costs.

[0012] In order to protect the operators, the equipment is also equipped with an isolation component. The isolation component is located on the side of the spraying mechanism. Its core is a transparent film, which can completely isolate the spraying area to prevent paint from splashing into the working environment. An operating cover is set on the film for manual operation. The operator does not need to directly contact the spraying area during the spraying process, which greatly reduces the risk of inhaling harmful substances and improves the safety and health protection of the operation.

[0013] In addition, in order to further deal with the residual pollutants in the spraying, the equipment is equipped with an exhaust duct on the upper part of the spraying mechanism. The lower end of the exhaust duct is perpendicular to the upper part of the spraying mechanism, and the small amount of paint particles that are not absorbed by the water curtain are collected and discharged in time through strong suction. This design can prevent the paint particles from spreading in the air and reduce secondary pollution to the environment. Through the comprehensive design of the water curtain recovery system, isolation components and exhaust ducts, resource recycling, pollutant emission control and personnel health protection are effectively realized, providing an efficient, safe and environmentally friendly solution for spraying operations.

[0014] The spraying mechanism consists of a spraying box, a spraying space, a water curtain slope, a drainage strip, a reflux assembly and a water curtain assembly. Its design focuses on efficiently collecting splashed paint generated during the spraying process, reducing the spread of pollutants, and optimizing equipment operation efficiency.

[0015] The spray box is the main operating space for the entire spraying work. It is firmly mounted on the bracket to support and protect other core components. The spray space is opened on the side of the spray box to accommodate the spraying operation. The cross-section is designed as a quadrilateral structure. This structure facilitates the installation and operation of the spraying equipment and provides an ideal geometric layout for pollutant control. In the spraying space, one of the opposite sides is specially set as a water curtain slope, which is a key part of the equipment's environmental protection function. The water curtain slope can form a continuous water curtain, which effectively intercepts and absorbs the paint particles splashed during the spraying operation to prevent them from spreading to the external environment.

[0016] The water curtain slope is equipped with drainage strips designed as a wave-shaped structure. The wave-shaped drainage strips can disperse the water flow and evenly guide the water to distribute on the water curtain slope, thus forming a stable water curtain. This uniform water curtain structure not only improves the efficiency of capturing splashed paint, but also avoids local pollution or poor equipment operation caused by uneven water flow.

[0017] A water curtain assembly is installed on the upper part of the water curtain slope. The function of the water curtain assembly is to spray the filtered water flow onto the slope with appropriate pressure to form a stable water curtain cycle. At the same time, a return assembly is equipped at the bottom of the slope to collect splashed paint and other pollutants captured by the water curtain. The return assembly can transport the collected liquid to the filtration system and recycle it after preliminary treatment. This closed-loop water circulation design significantly reduces water consumption and reduces equipment operating costs.

[0018] In order to further improve the efficiency of collecting splashed paint, the angle between the slope of the water curtain and the plane where the exhaust duct is located is designed to be a right angle. This design can maximize the suction area and suction force of the exhaust duct, so that it can achieve the best effect when capturing residual paint particles that are not intercepted by the water curtain. At the same time, this angle optimizes the air flow and ensures that the air quality in the spraying space is effectively controlled.

[0019] In short, the spraying mechanism combines environmental protection performance with functional efficiency through the stable layout of the spray box, the innovative design of the water curtain slope, the flow equalization function of the wavy drainage strip, and the efficient circulation mechanism of the water curtain assembly and the return flow assembly, providing a safe, green and economical solution for spraying operations.

[0020] The reflux assembly consists of a reflux trough, a reflux block and a reflux strip, and its main function is to collect and guide the water flow that forms the water curtain to ensure efficient recovery and recycling of water resources.

[0021] The reflux trough is located below the slope of the water curtain. It serves as the bottom collection device of the entire water curtain system and is used to collect the water flowing down from the slope. A specially designed reflux block is installed in the reflux trough. The reflux block diverts and preliminarily guides the collected water flow to make the water flow more evenly distributed, which is convenient for subsequent treatment and recycling. The reflux block is designed as an arc block with a reflux port at the bottom. This arc design helps to reduce water turbulence, optimize the flow rate and direction of the water flow, and improve the stability of the system operation.

[0022] In addition, the return strip is installed on the central axis of the return block to further guide the water flow. The return strip can guide the water flow into the water storage tank, making the water flow process more stable and continuous, avoiding loss or overflow caused by water turbulence. This design improves the efficiency of water resource recovery while ensuring the continuity and overall operation of the water curtain system.

[0023] Through the coordinated work of the above components, the reflux component realizes the efficient collection and guidance of water flow, provides a stable guarantee for the recycling water utilization of the entire spraying equipment, helps to reduce water consumption, and improves the environmental performance and economy of the equipment.

[0024] The water curtain assembly is composed of an interception block, an interception surface and a water outlet, and is intended to optimize the distribution and flow stability of water flow, ensure the uniform formation of the water curtain, and improve the working efficiency of the equipment.

[0025] The interception block is installed on the upper part of the water curtain slope and is the first processing link for water entering the water curtain system. The function of the interception block is to make a preliminary transition and temporary storage of the water flow, so that the water flow pumped from the water tank will not directly impact the water curtain slope, thereby avoiding water curtain quality problems caused by too fast or uneven water flow. A curved interception surface is designed on the inner side of the interception block. This design is the key to the smooth transition of water flow. The curved surface can not only effectively reduce the speed of water flow, but also buffer the water flow, making it more stable and uniform. This design can greatly improve the continuity and coverage of the water curtain formation and reduce the omission of splashing paint.

[0026] The water outlet is linearly opened below the interception block and adopts a semicircular structure. This semicircular design can make the water flow more evenly distributed and reduce the impact of the water flow, thereby providing a more stable water supply for the water curtain slope. In addition, after the water flow is pumped out from the water pump in the water storage tank, it is evenly diverted through the synergy of the interception block and the water outlet to form a stable water curtain. This design not only enhances the performance of the water curtain assembly, but also improves the efficiency and environmental protection effect of the entire spraying system.

[0027] Through precise water flow control, the water curtain assembly achieves full utilization of water resources and efficient support for spraying operations, providing guarantees for the environmental performance and operational reliability of the equipment.

[0028] The filter assembly consists of a filter plate, a filter channel and a filter convex ring, and is designed specifically to improve water resource utilization efficiency and reduce pollution, ensuring the stable operation and environmental protection performance of the water curtain system.

[0029] The filter plate is installed inside the water tank and is located at the higher part of the water tank. This installation design fully considers the characteristics of pollutants during the spraying process. The main pollutants generated by the spraying operation are mostly solid particles or heavy metal compounds. These pollutants are usually naturally deposited at the bottom of the water tank due to their large mass. Therefore, placing the filter plate at a higher position can effectively prevent most of the sediment from being pumped into the circulation system, thereby reducing the impact on the water pump and subsequent water curtain components and extending the service life of the equipment.

[0030] A filter channel is opened in the middle of the filter plate to guide the water flow through the filter system. The design of the channel allows the water flow to further separate impurities before entering the water pump, improving the cleanliness of the water quality. In addition, the inner side of the filter channel is equipped with a filter convex ring, which can increase the contact area when the water flows through and enhance the filtering effect. At the same time, the structure of the convex ring helps to block tiny pollutants, ensuring that the water entering the circulating water system is cleaner, thereby improving the performance and environmental protection of the water curtain.

[0031] Through the cooperation of the filter plate, filter channel and filter convex ring, the filter assembly can effectively reduce the entry of pollutants into the circulating water system, providing reliable technical guarantee for the efficient operation of the spraying equipment and the recycling of resources.

[0032] The filter channel is designed as a tapered structure with a large bottom and a small top. This tapered design fully considers the efficiency of water flow filtration and flow rate control. The larger bottom inlet can accommodate more water flow and reduce the resistance when the water flow enters the channel, while the gradually narrowing top outlet can concentrate the water flow, enhance the filtration effect, and make the water flowing to the water curtain assembly more uniform and stable.

[0033] The filter convex rings are arranged in sequence along the lateral axis of the filter channel. These convex rings play a multi-stage filtering role in the process of water flow rising. Some large pollutants will be gradually intercepted and deposited when the water flows through each convex ring, effectively preventing them from entering the water curtain system. Through this step-by-step filtering method, the pollutant content in the water is greatly reduced, thereby ensuring that the water output by the water curtain assembly is cleaner.

[0034] This design not only improves the efficiency of the filtering components, but also effectively extends the service life of the water curtain system, provides reliable support for spraying operations, and further embodies the combination of environmental protection and high efficiency.

[0035] The isolation assembly includes fixing bolts, a transparent film, a magnetic strip and an operating cover, which is intended to effectively isolate the spraying space from the external environment, reduce paint splash pollution, and provide a convenient operating method for operators.

[0036] The fixing bolts are installed on the surface of the spraying mechanism to firmly fix the transparent film on the side of the spraying mechanism. As the core part of the isolation component, the transparent film can effectively block the splash of paint during the spraying process and protect the surrounding environment and operators from the influence of harmful substances. The upper part of the transparent film is connected to the spraying mechanism through the fixing bolts to ensure its stability and safety in use.

[0037] In order to facilitate the installation and removal of transparent film, magnetic strips are installed on the edge of the film. Through magnetic force, the magnetic strips enable the transparent film to be quickly and firmly connected to the spraying mechanism, and can be easily removed when needed, making it convenient for operators to quickly pick up and place automotive parts or perform equipment maintenance. This design not only improves work efficiency, but also ensures the flexibility and operability of the equipment.

[0038] An operating cover is set in the middle of the transparent film. The design of the operating cover makes it easy for the operator to reach into the spraying space for manual spraying. Through the operating cover, the operator can easily control the spraying tool and perform precise spraying operations while avoiding direct contact with paint splashes, thereby ensuring the health and safety of the operator.

[0039] In summary, the isolation component, through the coordination of transparent film, magnetic strip and operating cover, not only effectively protects the environment and operators, but also enhances the flexibility and safety during the operation.

[0040] The beneficial effects of the present invention are as follows:

[0041] 1. The present invention adopts a fully enclosed environment for spraying operations by setting up a spraying mechanism. This design has significant benefits in many aspects, especially in reducing environmental pollution, protecting the safety of workers and improving the efficiency of water resource utilization. The use of a fully enclosed environment can effectively reduce the leakage of paint splashes during the spraying process. In traditional spraying operations, paint splashes often spread to the surrounding environment, which not only increases air pollution, but may also adhere to surrounding objects and cause secondary pollution. Through the design of a fully enclosed environment, all splashed paint is confined to a confined space, avoiding the diffusion of paint particles into the air or other areas, greatly reducing the risk of environmental pollution. In this way, the pollution sources in the operating area can be effectively controlled, meeting modern environmental protection requirements.

[0042] 2. The fully enclosed design of the present invention can significantly improve the safety of the staff. In the traditional spraying process, the operator is exposed to harmful paint vapor and splashes for a long time, which can easily cause harm to health. By adopting a closed environment and combining the dual absorption method of water curtain and air suction, the risk of contact with splashed paint and harmful gases can be greatly reduced, ensuring the safety and health of the operators. The paint splashes generated during the spraying process are doubly absorbed by the water curtain and the air suction system. The water curtain can absorb and collect splashed paint particles through water flow, reducing pollutants in the air. At the same time, the air suction system can process paint particles that are not absorbed by the water curtain, ensuring that all splashes are effectively collected to prevent them from polluting the environment.

[0043] 3. The recycling of water resources is the focus of the present invention. Through the design of the reflux component, the collected water can be reused after filtration to form a closed water circulation system. This not only effectively reduces water consumption and reduces operating costs, but also reduces water waste, conforms to the concept of environmental protection, and further improves the sustainability of the system. The present invention not only effectively reduces environmental pollution and protects the health of workers, but also optimizes resource utilization efficiency through the setting of a fully enclosed spraying environment, combined with a dual absorption system of water curtain and air suction, and repeated recycling of water resources, and has significant environmental, economic and safety advantages.

DETAILED DESCRIPTION

[0054] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0055] like Figure 1-7 As shown, an environmentally friendly automobile spraying equipment includes a bracket 1, a spraying mechanism 2, an isolation component 3 and an exhaust duct 4. The design aims to reduce the pollution to the environment during the spraying process, improve resource utilization, and provide a safer working environment for operators.

[0056] The support 1 of the equipment is firmly installed on the ground to support the operation of the entire spraying equipment. The spraying mechanism 2 is installed above the support 1 and is the core part of the equipment. In the spraying mechanism 2, the water curtain assembly 26 forms a continuous water curtain by intercepting and diverting the water flow on the water curtain slope 23. The water curtain can not only effectively absorb and intercept the paint particles splashed during the spraying process, but also greatly reduce the possibility of them escaping into the air. In this way, the exhaust gas and solid pollutants generated during the spraying process can be significantly reduced.

[0057] The water flowing back from the water curtain assembly 26 will flow to the return assembly 25 in the equipment. After preliminary filtering by the filter assembly 28, the water can be recycled again to form a closed water resource utilization circulation system. The filtered water is used again to form the water curtain, which can not only absorb more splashed paint, but also maximize the use of water resources. This design significantly reduces water consumption, meets environmental protection requirements, and reduces operating costs.

[0058] In order to protect the operator, the equipment is also equipped with an isolation component 3. The isolation component 3 is located on the side of the spraying mechanism 2. Its core is a transparent film 32, which can completely isolate the spraying area to prevent paint from splashing into the working environment. An operating sleeve 34 is set on the film for manual operation. The operator does not need to directly contact the spraying area during the spraying process, which greatly reduces the risk of inhaling harmful substances and improves the safety and health protection of the operation.

[0059] In addition, in order to further deal with the pollutants remaining in the spraying, the equipment is equipped with an exhaust duct 4 on the upper part of the spraying mechanism 2. The lower end of the exhaust duct 4 is perpendicular to the upper part of the spraying mechanism 2, and the small amount of paint particles not absorbed by the water curtain are collected and discharged in time through strong suction. This design can prevent the paint particles from spreading in the air and reduce secondary pollution to the environment. Through the comprehensive design of the water curtain recovery system, isolation component 3 and exhaust duct 4, resource recycling, pollutant emission control and personnel health protection are effectively realized, providing an efficient, safe and environmentally friendly solution for spraying operations.

[0060] like Figure 2-3 As shown, the spraying mechanism 2 consists of a spraying box 21, a spraying space 22, a water curtain slope 23, a drainage strip 24, a reflux assembly 25 and a water curtain assembly 26. Its design focuses on efficiently collecting splashed paint generated during the spraying process, reducing the spread of pollutants, and optimizing the equipment operation efficiency.

[0061] The spray box 21 is the main operating space for the entire spraying operation. It is firmly mounted on the bracket 1 to support and protect other core components. The spray space 22 is opened on the side of the spray box 21 to accommodate the spraying operation, and the cross-section is designed as a quadrilateral structure. This structure facilitates the installation and operation of the spraying equipment, and provides an ideal geometric layout for the control of pollutants. In the spray space 22, one of the opposite sides is specially set as a water curtain slope 23, which is a key part of the environmental protection function of the equipment. The water curtain slope 23 can form a continuous water curtain, which can effectively intercept and absorb paint particles splashed during the spraying operation to prevent them from spreading to the external environment.

[0062] A drainage strip 24 is installed on the water curtain slope 23, which is designed as a wave-shaped structure. The wave-shaped drainage strip 24 can disperse the water flow and evenly guide the water to be distributed on the water curtain slope 23, thereby forming a stable water curtain. This uniform water curtain structure not only improves the efficiency of capturing splashed paint, but also avoids local pollution or poor equipment operation caused by uneven water flow.

[0063] A water curtain assembly 26 is installed on the upper part of the water curtain slope 23. The function of the water curtain assembly 26 is to spray the filtered water flow onto the slope with appropriate pressure to form a stable water curtain cycle. At the same time, a return assembly 25 is provided at the bottom of the slope to collect splashed paint and other pollutants captured by the water curtain. The return assembly 25 can transport the collected liquid to the filtration system and recycle it after preliminary treatment. This closed-loop water circulation design significantly reduces water resource consumption and reduces equipment operating costs.

[0064] In order to further enhance the collection efficiency of splashed paint, the angle between the water curtain slope 23 and the plane where the exhaust duct 4 is located is designed to be a right angle. This design can maximize the suction area and suction force of the exhaust duct 4, so that it can achieve the best effect when capturing residual paint particles that are not intercepted by the water curtain. At the same time, this angle optimizes the air flow and ensures that the air quality in the spraying space 22 is effectively controlled.

[0065] In summary, the spraying mechanism 2 achieves a combination of environmental protection performance and functional efficiency through the stable layout of the spray box 21, the innovative design of the water curtain slope 23, the flow equalization function of the wavy drainage strip 24, and the efficient circulation mechanism of the water curtain assembly 26 and the return flow assembly 25, providing a safe, green and economical solution for spraying operations.

[0066] like Figure 4 As shown, the reflux assembly 25 is composed of a reflux groove 251, a reflux block 252 and a reflux strip 253, and its main function is to collect and guide the water flow forming a water curtain to ensure efficient recovery and recycling of water resources.

[0067] The reflux trough 251 is located below the water curtain slope 23 and serves as the bottom collection device of the entire water curtain system, which is used to collect the water flowing down from the slope. A specially designed reflux block 252 is installed in the reflux trough 251. The reflux block 252 diverts and preliminarily guides the collected water flow to make the water flow distribution more uniform, which is convenient for subsequent processing and recycling. The reflux block 252 is designed as an arc block with a reflux port at the bottom. This arc design helps to reduce water turbulence, optimize the flow rate and direction of the water flow, and improve the stability of the system operation.

[0068] In addition, the return strip 253 is installed on the central axis of the return block 252 to further guide the water flow. The return strip 253 can guide the water flow into the water storage tank 27, making the water flow entering the process more stable and continuous, and avoiding loss or overflow caused by water flow turbulence. This design improves the water resource recovery efficiency while ensuring the continuity and overall operation effect of the water curtain system.

[0069] Through the coordinated work of the above components, the reflux component 25 realizes the efficient collection and guidance of water flow, provides a stable guarantee for the recycling water utilization of the entire spraying equipment, helps to reduce water consumption, and improves the environmental protection performance and economy of the equipment.

[0070] like Figure 5 As shown, the water curtain assembly 26 is composed of an interception block 261, an interception surface 262 and a water outlet 263, which is intended to optimize the distribution and flow stability of the water flow, ensure the uniform formation of the water curtain, and improve the working efficiency of the equipment.

[0071] The interception block 261 is installed on the upper part of the water curtain slope 23 and is the first processing link for water entering the water curtain system. The function of the interception block 261 is to make a preliminary transition and temporary storage of the water flow, so that the water flow pumped from the water storage tank 27 will not directly impact the water curtain slope 23, thereby avoiding water curtain quality problems caused by too fast or uneven water flow. An arc-shaped interception surface 262 is designed on the inner side of the interception block 261. This design is the key to the smooth transition of the water flow. The arc-shaped surface can not only effectively reduce the speed of the water flow, but also buffer the water flow, making it more stable and uniform. This design can greatly improve the continuity and coverage of the water curtain formation and reduce the omission of splashing paint.

[0072] The water outlet 263 is linearly opened below the interception block 261 and adopts a semicircular structure. This semicircular design can make the water flow distribution more uniform and reduce the impact force of the water flow, thereby providing a more stable water supply for the water curtain slope 23. In addition, after the water flow is pumped out from the water pump in the water storage tank 27, it is evenly diverted through the synergistic effect of the interception block 261 and the water outlet 263 to form a stable water curtain. This design not only enhances the performance of the water curtain assembly 26, but also improves the efficiency and environmental protection effect of the entire spraying system.

[0073] Through precise water flow control, the water curtain assembly 26 achieves full utilization of water resources and efficient support for spraying operations, providing guarantees for the environmental performance and operational reliability of the equipment.

[0074] The filter assembly 28 is composed of a filter plate 281, a filter channel 282 and a filter convex ring 283, and is designed to improve water resource utilization efficiency and reduce pollution, thereby ensuring stable operation and environmental protection performance of the water curtain system.

[0075] like Figure 6 As shown, the filter plate 281 is installed inside the water tank 27 and is located at the higher part of the water tank 27. Such an installation design fully considers the characteristics of pollutants during the spraying process. The main pollutants generated by the spraying operation are mostly solid particles or heavy metal compounds. These pollutants are usually naturally deposited at the bottom of the water tank 27 due to their large mass. Therefore, placing the filter plate 281 at a higher position can effectively prevent most of the sediment from being drawn into the circulation system, thereby reducing the impact on the water pump and the subsequent water curtain assembly 26, and extending the service life of the equipment.

[0076] A filter channel 282 is provided in the middle of the filter plate 281 to guide the water flow through the filter system. The design of the channel enables the water flow to further separate impurities before entering the water pump, thereby improving the cleanliness of the water quality. In addition, the inner side of the filter channel 282 is equipped with a filter convex ring 283, which can increase the contact area when the water flows through and enhance the filtering effect. At the same time, the structure of the convex ring helps to block tiny pollutants and ensure that the water entering the circulating water system is cleaner, thereby improving the performance and environmental protection of the water curtain.

[0077] Through the cooperation of the filter plate 281, the filter channel 282 and the filter convex ring 283, the filter assembly 28 can effectively reduce the pollutants entering the circulating water system, providing a reliable technical guarantee for the efficient operation of the spraying equipment and the recycling of resources.

[0078] The filter channel 282 is designed as a tapered structure with a larger bottom and a smaller top. This tapered design fully considers the efficiency of water flow filtration and flow rate control. The larger bottom inlet can accommodate more water flow and reduce the resistance when the water flow enters the channel, while the gradually narrowing top outlet can concentrate the water flow, enhance the filtration effect, and make the water flowing to the water curtain assembly 26 more uniform and stable.

[0079] The filter convex rings 283 are arranged in sequence along the lateral axis of the filter channel 282. These convex rings play a multi-stage filtering role in the process of water flow rising. Some large pollutants will be gradually intercepted and deposited when the water flows through each convex ring, effectively preventing them from entering the water curtain system. Through this step-by-step filtering method, the pollutant content in the water is greatly reduced, thereby ensuring that the water flow output by the water curtain assembly 26 is cleaner.

[0080] This design not only improves the efficiency of the filter assembly 28, but also effectively extends the service life of the water curtain system, provides reliable support for spraying operations, and further embodies the combination of environmental protection and high efficiency.

[0081] like Figure 7 As shown, the isolation assembly 3 includes a fixing bolt 1, a transparent film 32, a magnetic strip 33 and an operating sleeve 34, which is intended to effectively isolate the spraying space 22 from the external environment, reduce paint splash pollution, and provide a convenient operation method for operators.

[0082] The fixing bolt 1 is installed on the surface of the spraying mechanism 2 to firmly fix the transparent film 32 on the side of the spraying mechanism 2. As the core part of the isolation component 3, the transparent film 32 can effectively block the splash of paint during the spraying process and protect the surrounding environment and operators from the influence of harmful substances. The upper part of the transparent film 32 is connected to the spraying mechanism 2 by the fixing bolt 1 to ensure its stability and safety in use.

[0083] In order to facilitate the installation and removal of the transparent film 32, a magnetic strip 33 is installed at the edge of the film. The magnetic strip 33 uses magnetic force to enable the transparent film 32 to be quickly and firmly connected to the spraying mechanism 2, and can be easily removed when necessary, so that the operator can quickly take and place automobile parts or perform equipment maintenance. This design not only improves work efficiency, but also ensures the flexibility and operability of the equipment.

[0084] An operating sleeve 34 is provided in the middle of the transparent film 32. The design of the operating sleeve 34 facilitates the operator to reach into the spraying space 22 for manual spraying. Through the operating sleeve 34, the operator can easily control the spraying tool and perform precise spraying operations while avoiding direct contact with paint splashes, thereby ensuring the health and safety of the operator. The isolation component 3, through the cooperation of the transparent film 32, the magnetic strip 33 and the operating sleeve 34, not only effectively protects the environment and the operator, but also enhances the flexibility and safety during the operation process.

[0085] During the working process of the present invention, the staff releases the fixation between the magnetic strip 33 and the spraying mechanism 2, places the automobile parts to be sprayed into the spraying space 22, and then re-fixes the transparent film 32 on the spraying mechanism 2 through the magnetic strip 33, so that the spraying space 22 forms a sealed environment, and starts the water pump on the water storage tank 27 and the fan arranged inside the exhaust pipe 4;

[0086] The water in the water storage tank 27 is pumped into the water curtain assembly 26 by a water pump. After the water flow is intercepted by the interception surface 262, it flows out evenly and stably through multiple water outlets 263. Under the action of the diversion strips 24 on the water curtain slope 23, a uniform and uniform water curtain is formed. The water flow forming the water curtain falls on the reflux block 252 to be divided left and right. Under the guidance of the reflux strips 253, it flows into the reflux groove 251 and enters the water storage tank 27.

[0087] There is recycled sewage in the lower part of the water storage tank 27. The pollutants in this part of sewage will naturally settle, and most of the pollutants will be deposited under the water storage tank 27. The relatively clean water in the upper part is filtered by the filter assembly 28 and then sucked into the water curtain assembly 26 by the water pump set at the top of the water storage tank 27 to form a water cycle.

[0088] The equipment is equipped with an exhaust duct 4 on the upper part of the spraying mechanism 2. A fan is installed inside the exhaust duct 4, and the lower end of the exhaust duct 4 is perpendicular to the upper part of the spraying mechanism 2. The small amount of paint particles not absorbed by the water curtain are collected and discharged in time through strong suction.

[0089] The preparation work is thus completed, and the worker can put both hands into the operation sleeve 34 to perform the spraying operation.
