Description

Technical Field

[0001] This utility model relates to the field of paint mist recovery and filtration, and in particular to a paint mist treatment and recovery device. Background Technology

[0002] Paint mist contains volatile organic compounds (VOCs) and fine particles, which not only pose a serious threat to the respiratory health of spray painters but also potentially pollute the atmospheric environment. These substances drift in the air, creating an invisible danger that can have long-term negative impacts on surrounding residents and the ecological environment. Currently, the commonly used method in spray painting operations is physical interception through filters. However, due to the drifting nature of particles during spraying, it is impossible to completely collect and treat the paint mist, resulting in low efficiency in paint mist treatment. Furthermore, the intercepted paint mist cannot be effectively recycled, leading to waste of water-based paint. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a paint mist exhaust gas treatment device that improves the efficiency of paint mist treatment.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a paint mist treatment and recovery device, including a paint mist treatment box, one end of which is an open end and the other end of which is a closed end. The paint mist treatment box is provided with a product fixing frame, a water curtain paint removal device, a filter screen mechanism and a cyclone separation device in sequence from the open end to the closed end. The cyclone separation device includes a cyclone tube, an air inlet is provided on the side of the cyclone tube, an air outlet is provided on the top of the cyclone tube, and a fan is provided at the bottom of the cyclone tube, which is also provided at the top of the closed end of the paint mist treatment box. The fan is connected to the air outlet at the top of the cyclone tube.

[0005] Furthermore, the water curtain paint removal device includes a water storage tank located at the top of the inside of the paint mist treatment box, a first water curtain nozzle located at the lower end of the water storage tank, and a first water receiving tank located below the first water curtain, so that the water falling from the first water curtain nozzle can fall into the first water receiving tank. It also includes a first return water pipe, with its two ends connected to the water storage tank and the first water receiving tank, respectively. It also includes a first water pump located on the first return water pipe, so that the water in the first water receiving tank can return to the water storage tank.

[0006] Furthermore, a first filter mechanism is provided at the water inlet of the first water pump.

[0007] Furthermore, the filter mechanism includes a paint removal filter, a second water curtain nozzle is provided above the paint removal filter, the inlet of the second water curtain nozzle is connected to a water storage tank, a second water receiving tank is provided below the paint removal filter for intercepting the water flow sprayed from the second water curtain nozzle, and a second return water pipe is also included. The two ends of the second return water pipe are respectively connected to the water storage tank and the second water receiving tank, and a second water pump is also included on the second return water pipe so that the water in the second water receiving tank can return to the water storage tank.

[0008] Furthermore, a second filtration mechanism is installed at the water inlet of the second water pump.

[0009] The beneficial effects of this utility model are:

[0010] 1. In this structure, a product fixing frame is set at the front of the paint mist treatment box, so that the operator can directly carry out painting operations inside the paint mist treatment box. A fan is set at the rear of the paint mist treatment box, so that the paint mist generated during operation can be directly treated by the water curtain paint removal device, the filter screen mechanism and the cyclone separation device, so that the paint mist will not drift into the air due to lack of treatment, thus ensuring human safety.

[0013] Figure 1 This is a schematic diagram of the structure of a paint mist treatment and recovery device according to an embodiment of this application.

[0014] Figure 2 This is a schematic diagram of the cyclone separator according to an embodiment of this application.

[0015] The components in the diagram are marked as follows: paint mist treatment box 1, product fixing frame 2, first water curtain nozzle 31, first water receiving tank 32, second water curtain nozzle 41, filter screen 42, cyclone separator 5, cyclone tube 51, air inlet 52, air outlet 53, fan 6, and water storage tank 7. Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] like Figure 1 As shown in the figure, an embodiment of this application discloses a paint mist treatment and recovery device, including a paint mist treatment box 1. One end of the paint mist treatment box 1 is an open end, and the other end of the paint mist treatment box 1 is a closed end. The paint mist treatment box 1 is provided with a product fixing frame 2, a water curtain paint removal device, a filter screen mechanism, and a cyclone separation device 5 in sequence from the open end to the closed end. The cyclone separation device 5 includes a cyclone cylinder 51. An air inlet 52 is provided on the side of the cyclone cylinder 51, and an air outlet 53 is provided on the top of the cyclone cylinder 51. The paint mist treatment box 1 is provided at the bottom of the cyclone cylinder 51. It also includes a fan 6 provided on the top of the closed end. The fan 6 is connected to the air outlet 53 on the top of the cyclone cylinder 51.

[0018] In practice, the operator installs the product to be painted on the product mounting bracket 2, stands in front of the product and performs the painting operation. During the painting process, the emitted paint mist is filtered first by the water curtain paint removal device under the action of the rear fan 6, and then filtered second by the filter screen mechanism. Then the gas is drawn in from the air inlet 52 of the cyclone separator 5, and gas-solid separation is performed inside the cyclone separator 5. The separated gas is discharged from the air outlet 53 of the cyclone separator 5, and the separated paint mist particles fall from the bottom of the cyclone separator 5 into the paint mist treatment box 1 for subsequent recycling.

[0019] In this structure, a product fixing bracket 2 is installed at the front of the paint mist treatment box 1, allowing operators to directly perform painting operations inside the paint mist treatment box 1. A fan is installed at the rear of the paint mist treatment box 1, so that the paint mist generated during operation can be directly treated by the three-layer water curtain paint removal device, the filter screen mechanism, and the cyclone separator 5. This prevents the paint mist from drifting into the air due to lack of treatment, thus ensuring human safety. At the same time, the use of the three-layer filtration device in this structure can achieve complete treatment of paint mist exhaust gas, thereby ensuring the cleanliness of the exhaust gas. In addition, the paint mist intercepted by the three layers will be collected by the water curtain paint removal device, the filter screen mechanism, and the cyclone separator 5 for subsequent recycling and reuse.

[0020] In this embodiment, the water curtain paint removal device includes a water storage tank 7 located at the top of the inner side of the paint mist treatment box 1. A first water curtain nozzle 31 is provided at the lower end of the water storage tank 7. A first water receiving tank 32 is provided below the first water curtain, so that the water falling from the first water curtain nozzle 31 can fall into the first water receiving tank 32. It also includes a first return water pipe, with its two ends connected to the water storage tank 7 and the first water receiving tank 32, respectively. It also includes a first water pump provided on the first return water pipe, so that the water in the first water receiving tank 32 can return to the water storage tank 7.

[0021] Specifically, a first filter mechanism is provided at the water inlet of the first water pump.

[0022] Specifically, the first water curtain nozzle 31 can spray water to form a water curtain structure. When the paint mist exhaust gas passes through the water curtain structure, the exhaust gas is washed by the water curtain, and most of the particles are washed into the first water receiving tank 32, thus forming the first layer of treatment for the paint mist exhaust gas. At the same time, the water in the first water receiving tank 32 can be recycled to the water storage tank 7 for reuse.

[0023] Specifically, the first filtration mechanism can be a filter screen, and the paint mist particles blocked by the filter screen can be returned to the first water receiving tank 32.

[0024] In this structure, a first filter mechanism is installed at the first water pump, which allows the water in the water curtain to be recycled, thereby reducing water waste. At the same time, the water curtain can treat the exhaust gas and flush away most of the paint mist in the paint mist exhaust gas, so that the paint particles are placed in the first water tank. During the continuous interception process, the paint concentration in the first water tank increases continuously. When the concentration reaches a certain level, the liquid in the first water tank can be recovered and replaced with new liquid. The recovery time can be set according to the actual situation, such as once a day or once a week.

[0025] In this embodiment, the filter mechanism includes a paint removal filter 42, a second water curtain nozzle 41 is provided above the paint removal filter 42, the inlet of the second water curtain nozzle 41 is connected to the water storage tank 7, a second water receiving tank is provided below the paint removal filter 42 for intercepting the water flow sprayed by the second water curtain nozzle 41, and a second return water pipe is also provided. The two ends of the second return water pipe are respectively connected to the water storage tank 7 and the second water receiving tank, and a second water pump is also provided on the second return water pipe so that the water in the second water receiving tank can return to the water storage tank 7.

[0026] It should be explained that the paint removal filter 42 in this application can be purchased externally, specifically it can be a glass fiber filter 42, a hollow ball filter plate, etc.

[0027] Specifically, a second filtration mechanism is provided at the water inlet of the second water pump.

[0028] Specifically, the paint mist exhaust gas treated by the water curtain undergoes a second filtration operation after passing through the filter screen 42. Tiny paint mist particles are intercepted on the filter screen 42. At the same time, the second water curtain nozzle 41 sprays water onto the filter screen 42, washing the paint mist particles adhering to the filter screen 42 into the second water tank at the bottom. Meanwhile, the water in the second water tank can be recycled to the water storage tank 7 for reuse.

[0029] In this structure, a second filtration mechanism is installed at the second water pump, which allows the water in the water curtain to be recycled, thereby reducing water waste. At the same time, by continuously cleaning the filter screen 42, the interception effect of the filter screen 42 on paint mist can be guaranteed, thereby ensuring the treatment efficiency of paint mist exhaust gas. Meanwhile, the washed paint particles fall into the second water tank. During the continuous washing process, the paint concentration in the second water tank continuously increases. When the concentration reaches a certain level, the liquid in the second water tank can be recovered and replaced with new liquid. The recovery time can be set according to the actual situation, such as once a day or once a week.

[0030] In summary, this structure enables the recycling and reuse of paint particles, thereby ensuring that paint waste is reduced while treating exhaust gas.

[0031] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
