Abstract
Description
Technical Field
[0001] This application relates to the field of spraying technology, and more particularly to a water curtain spraying machine. Background Technology
[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets with the help of pressure or centrifugal force and apply them to the surface of the object. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivative methods of the above basic spraying forms, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying.
[0003] Traditional spraying processes are widely used in industrial production, but the emission of volatile organic compounds (VOCs) and other harmful substances during the spraying process not only pollutes the environment but also harms human health. With the increasing awareness of environmental protection and technological progress, more and more companies are seeking more efficient and environmentally friendly spraying technologies to replace traditional methods.
[0004] Currently, a variety of new spraying technologies have emerged in the market, such as dry filtration spraying and electrostatic spraying. Although these technologies can reduce pollutant emissions to some extent, they still have certain limitations and room for improvement. In particular, the emission of volatile organic compounds (VOCs) and other harmful substances generated during the painting process not only pollutes the environment but also harms human health.
[0005] Therefore, this application proposes a water curtain spray bed. Utility Model Content
[0006] This application proposes a water curtain spray bed to solve the problems mentioned in the background art. By turning on the switch to start the water pump, water enters the storage tank through the inlet pipe. The water in the storage tank then flows out along the outlet and the guide plate, carrying away volatile organic compounds (VOCs) and other harmful substances generated during spraying. The water then flows into a wastewater tank, where it circulates and flows out along the drain outlet, thereby improving purification efficiency. The water curtain spray bed can not only efficiently remove large particles but also effectively capture fine particles (such as PM2.5), significantly improving air purification and greatly enhancing the practicality of the device.
[0007] To achieve the above objectives, this application adopts the following technical solution:
[0008] A water curtain spraying machine includes a spraying machine body, a switch, a water spraying mechanism, a cleaning mechanism, a limiting mechanism, and a lighting mechanism. The spraying machine body is provided with a station for the test piece to be sprayed. The switch is fixedly connected to the outside of the spraying machine body. The water spraying mechanism includes a water inlet pipe, a water storage tank, a water outlet, a guide plate, a sewage tank, and a drain outlet.
[0009] In a preferred embodiment, the water storage tank is located inside the upper part of the spray bed body, and a water inlet pipe is fixedly connected to the spray bed body, with one end of the water inlet pipe communicating with the water storage tank. A water outlet is provided on the spray bed body, and the water outlet is communicating with the water storage tank.
[0010] By turning on the switch to start the water pump, water enters the water storage tank through the inlet pipe, and then the water in the storage tank flows out through the outlet, thereby improving the practicality of the device.
[0011] In a preferred embodiment, a wastewater tank is provided at the bottom of the spray bed body, and a drain outlet is provided inside the spray bed body, and the drain outlet is connected to the wastewater tank;
[0012] Water flows into the sewage tank, then circulates within the tank before flowing out through the drain, thereby improving purification efficiency. The water curtain spray bed not only efficiently removes large particles but also effectively captures fine particles (such as PM2.5), significantly enhancing air purification and thus improving the practicality of the device.
[0013] In a preferred embodiment, the spray bed body is provided with a guide plate, and the top of the guide plate abuts against the water outlet, and the bottom of the sewage tank abuts against the sewage tank.
[0014] By allowing water to flow out along the guide plate, volatile organic compounds (VOCs) and other harmful substances generated during spraying can be carried away, thereby improving the practicality of the device.
[0015] In a preferred embodiment, the cleaning mechanism includes a motor, a turbine, a worm gear, a screw, a moving plate, and a brush. The turbine is rotatably connected inside the spray bed body. The worm gear is rotatably connected inside the spray bed body, and the worm gear is meshed with the turbine. The motor is fixedly connected to the outside of the spray bed body, and the output end of the motor extends into the inside of the spray bed body and is fixedly connected to the turbine. The motor and the switch are electrically connected through wires.
[0016] By turning on the switch to start the motor, the motor will drive the turbine to rotate, thereby improving the practicality of the device.
[0017] In a preferred embodiment, a screw is rotatably connected to the main body of the sprayer and above the sewage tank, and one end of the screw is fixedly connected to one end of the worm gear. A movable plate is threaded onto the outside of the screw, and a brush is provided at the bottom of the movable plate, with the bottom of the brush in contact with the surface of the sewage tank.
[0018] When the turbine rotates, it meshes with the worm gear, causing the screw to rotate. When the screw rotates, it causes the moving plate to move back and forth. During the movement of the moving plate, the brush cleans the sediment on the surface of the sewage tank. Therefore, the water curtain sprayer does not need to replace expensive filter elements or activated carbon. It only needs to clean the sewage tank regularly, which greatly reduces the user's operating costs and improves the practicality of the device.
[0019] In a preferred embodiment, the limiting mechanism includes a limiting rod and a limiting hole. The limiting rod is fixedly connected inside the sewage tank, and the movable plate is slidably connected to the limiting rod through the limiting hole.
[0020] By setting a limiting mechanism, the moving plate will move synchronously on the limiting rod through the limiting hole during the moving process, thereby improving the stability of the moving plate during movement and preventing shaking or rotation that would affect the cleaning effect of the brush, thus improving the practicality of the device.
[0021] In a preferred embodiment, the lighting mechanism includes a mounting plate and a lamp. The mounting plate is fixedly connected to the outside of the spray bed body, and the lamp is fixedly connected to the mounting plate. The lamp is electrically connected to a switch via a wire.
[0022] By setting up a lighting mechanism and turning on the lights with a switch, the lighting effect can be improved, providing brightness for workpiece spraying and thus enhancing the practicality of the device.
[0023] The beneficial effects of this application are:
[0024] 1. This water curtain spray bed, when the switch is turned on and the water pump is started, allows water to enter the water storage tank through the inlet pipe. Then, the water in the storage tank flows out along the outlet and the guide plate, which can carry away volatile organic compounds (VOCs) and other harmful substances generated during spraying. The water flows into the wastewater tank through the guide plate, and then the water in the wastewater tank circulates and flows out along the drain outlet, thereby improving the purification efficiency. The water curtain spray bed can not only efficiently remove large particles, but also effectively capture fine particles (such as PM2.5), significantly improving the air purification effect and greatly enhancing the practicality of the device.
[0025] 2. This water curtain spray bed, by setting up a cleaning mechanism, can periodically clean the sewage tank. By turning on the switch to start the motor, the motor drives the turbine to rotate. When the turbine rotates, it meshes with the worm gear to cause the screw to rotate. When the screw rotates, it causes the moving plate to move back and forth. During the movement of the moving plate, the brush cleans the sediment on the surface of the sewage tank. Therefore, the water curtain spray bed does not need to replace expensive filter elements or activated carbon. It only needs to clean the sewage tank periodically, which greatly reduces the user's operating costs and greatly improves the practicality of the device. Attached Figure Description

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0032] Reference Figure 1-4 A water curtain spraying machine includes a spraying machine body 1, a switch 3, a water spraying mechanism 4, a cleaning mechanism 5, a limiting mechanism 6, and a lighting mechanism 7. The spraying machine body 1 is provided with a test piece station 2 to be sprayed. The switch 3 is fixedly connected to the outside of the spraying machine body 1. The water spraying mechanism 4 includes a water inlet pipe 41, a water storage tank 42, a water outlet 43, a guide plate 44, a sewage tank 45, and a drain outlet 46.
[0033] Reference Figure 1-3 The water storage tank 42 is located inside the upper part of the spray bed body 1. A water inlet pipe 41 is fixedly connected to the spray bed body 1, and one end of the water inlet pipe 41 is connected to the water storage tank 42. A water outlet 43 is provided on the spray bed body 1, and the water outlet 43 is connected to the water storage tank 42. By turning on the switch 3 to start the water pump, water enters the water storage tank 42 from the water inlet pipe 41, and then the water in the water storage tank 42 flows out along the water outlet 43, thereby improving the practicality of the device.
[0034] Reference Figure 1-3The spray bed body 1 has a sewage tank 45 at its bottom interior and a drain outlet 46 inside, which is connected to the sewage tank 45. Water flows into the sewage tank 45, circulates in the sewage tank 45, and then flows out along the drain outlet 46, thereby improving the purification efficiency. The water curtain spray bed can not only efficiently remove large particles, but also effectively capture fine particles (such as PM2.5), significantly improving the air purification effect and thus enhancing the practicality of the device.
[0035] Reference Figure 1-3 The spraying body 1 is provided with a guide plate 44, and the top of the guide plate 44 abuts against the water outlet 43, and the bottom of the sewage tank 45 abuts against the sewage tank 45. As water flows out along the guide plate 44, it can carry away volatile organic compounds (VOCs) and other harmful substances generated during spraying, thereby improving the practicality of the device.
[0036] Reference Figure 1-4 The cleaning mechanism 5 includes a motor 51, a turbine 52, a worm gear 53, a screw 54, a moving plate 55, and a brush 56. The turbine 52 is rotatably connected inside the spray bed body 1. The worm gear 53 is rotatably connected inside the spray bed body 1, and the worm gear 53 and the turbine 52 are meshed together. The motor 51 is fixedly connected to the outside of the spray bed body 1, and the output end of the motor 51 extends into the inside of the spray bed body 1 and is fixedly connected to the turbine 52. The motor 51 is electrically connected to the switch 3 through a wire. By turning on the switch 3 to start the motor 51, the motor 51 will drive the turbine 52 to rotate, thereby improving the practicality of the device.
[0037] Reference Figure 1-4 A screw 54 is rotatably connected to the main body 1 of the spray bed and located above the sewage tank 45. One end of the screw 54 is fixedly connected to one end of the worm gear 53. A movable plate 55 is threadedly connected to the outside of the screw 54. A brush 56 is provided at the bottom of the movable plate 55, and the bottom of the brush 56 contacts the surface of the sewage tank 45. When the worm gear 52 rotates, it meshes with the worm gear 53 to cause the screw 54 to rotate. When the screw 54 rotates, it causes the movable plate 55 to move back and forth. During the movement of the movable plate 55, the brush 56 cleans the sediment on the surface of the sewage tank 45. Therefore, the water curtain spray bed does not need to replace expensive filter elements or activated carbon. It only needs to clean the sewage tank 45 regularly, which greatly reduces the user's operating costs and improves the practicality of the device.
[0038] Reference Figure 1-3The limiting mechanism 6 includes a limiting rod 61 and a limiting hole 62. The limiting rod 61 is fixedly connected inside the sewage tank 45, and the moving plate 55 is slidably connected to the limiting rod 61 through the limiting hole 62. By setting the limiting mechanism 6, during the movement of the moving plate 55, the moving plate 55 will move synchronously on the limiting rod 61 through the limiting hole 62, thereby improving the stability of the moving plate 55 during movement and preventing shaking or rotation that would affect the cleaning effect of the brush 56, thus improving the practicality of the device.

The lamp 72 is fixedly connected to the mounting plate 71, and the lamp 72 is electrically connected to the switch 3 through a wire. By setting up the lighting mechanism 7 and turning on the lamp 72 through the switch 3, the lighting effect can be improved, providing brightness for workpiece spraying, thereby improving the practicality of the device.
[0040] Working principle: The inlet pipe 41 is connected to an external water pump. During use, the pump is started by turning on switch 3, allowing water to enter the storage tank 42 through the inlet pipe 41. The water in the storage tank 42 then flows out through the outlet 43 and the guide plate 44, carrying away volatile organic compounds (VOCs) and other harmful substances generated during spraying. The water then flows through the guide plate 44 into the wastewater tank 45, where it circulates and flows out through the drain 46, thus improving purification efficiency. The water curtain spray bed can not only efficiently remove large particles but also effectively capture fine particles (such as PM2.5). This significantly improves the air purification effect. By setting up the cleaning mechanism 5, the sewage tank 45 can be cleaned regularly. By turning on the switch 3 to start the motor 51, the motor 51 drives the turbine 52 to rotate. When the turbine 52 rotates, it will mesh with the worm gear 53 to cause the screw 54 to rotate. When the screw 54 rotates, it will cause the moving plate 55 to move back and forth. During the movement of the moving plate 55, the brush 56 cleans the sediment on the surface of the sewage tank 45. Thus, the water curtain sprayer does not need to replace expensive filter elements or activated carbon. It only needs to clean the sewage tank 45 regularly, which greatly reduces the user's operating costs.
