The wind guiding cone 15 is arranged above the center of the cyclone disc 16; The upper spraying pipe 41, the lower spraying pipe 42 and the operating spraying pipe 43 are installed through a spraying pipe installation port 40 as Figure 3 shown. The number of the spraying pipe installation ports 40 is 3. Among them, 2 are arranged on the side plate of the box body, and 1 is arranged on the side wall of the water tank.

[0025] The water curtain type paint spraying and oil mist removing device provided by the above embodiment adopts the water curtain oil mist removing method and combines the filtering water curtain paper 11, the filtering barrel 12 and the spraying system to achieve multi-channel filtering, can obtain a better paint mist treatment effect, can avoid environmental pollution, and ensure the safe production of the workshop and the physical health of the operating personnel; At the same time, the device has a simple structure, low cost, small volume, light weight, and is convenient for installation and maintenance operations.

[0026] In this embodiment, the upper end of the water curtain plate 14 is connected to the upper rear side of the water trough 13. The lower end of the water curtain plate 14 hangs down above the water receiving area. A slag blocking plate 33 inclined forward is arranged between the lower end of the water curtain plate 14 and the water outlet 31. Specifically in implementation, the slag blocking plate 33 can make a part of the paint mist slag stay at the operating area 2, which is convenient for cleaning the paint mist slag at the operating area 2.

[0027] In this embodiment, the water pump 32 is arranged on one side of the pump water area far away from the water outlet 31. A slag separating plate 34 is arranged between the water pump 32 and the water outlet 31 in the pump water area. Specifically in implementation, the sewage flows to the slag separating plate 34 through the water outlet 31 for slag separation and filtration, and the filtered clean water is recycled through the water pump 32.

[0028] As a further improvement of this embodiment, the water pumping area is provided with at least two slag separation plates 34 between the water pump 32 and the water outlet 31. In specific implementation, two slag separation plates 34 can be provided between the water pump 32 and the water outlet 31, wherein the distance from the left slag separation plate 34 to the left plate of the water pumping area is equal to the distance from the right slag separation plate 34 to the right plate of the water pumping area.

[0029] The water curtain type paint spray degreasing mist device provided in the above embodiment has the following working process: the water curtain type paint spray degreasing mist device is started, and the fan 10 and the water pump 32 are started. The water in the pumping area of ​​the water tank 3 is pumped to the water tank 13 and the spraying system through the water pump 32. The spraying system includes an upper spray pipe 41 and a lower spray pipe 42 arranged at two positions below and inside the filter barrel 12, and an operating spray pipe 43 at the operating area 2. After the water tank 13 is filled with water, it overflows and flows to the water curtain plate 14, so that the water curtain plate 14 forms a water curtain, and then the water falls into the water tank 3. The water curtain plate 14 is not connected to the water in the water tank 3, so that a water curtain suction port is formed. The water curtain suction port generates suction under the action of the centrifugal fan. The worker generates paint mist during the painting operation in the working area 2. The paint mist enters the water curtain suction port through the suction force, forming the first filtration; the paint mist after the first filtration continues to be sucked into the filter barrel 12. A lower spray pipe 42 is installed below the filter barrel 12. Before entering the filter barrel 12, the paint mist is sucked into the lower spray pipe 42. The water mist produced by the spray pipe 42 is merged to form a second filter; the paint mist enters the filter barrel 12 after passing through the second filter. The internal structure of the filter barrel 12 is equipped with a cyclone disk 16, an air guide cone 15 and an upper spray pipe 41. Under the action of the cyclone disk 16 and the air guide cone 15, the paint mist forms a cyclone effect and enters the filter barrel 12, and merges with the water mist produced by the upper spray pipe 41 inside the filter barrel 12 to form a third filter; finally, the clean air with very little dust content enters the filter water curtain paper 11 for the fourth filtration, and the filtered clean air is discharged out of the equipment through a centrifugal fan.

[0030] In the above process, the sewage generated by the first three filtrations falls into the water tank 3, and the sewage flows to the slag separation plate 34 through the water outlet 31 for slag separation filtration, and the filtered clean water is circulated through the water pump 32.

[0031] When workers are spraying paint in the work area 2, a layer of paint mist will float on the water surface of the water tank 3 in the work area 2. The work spray pipe 43 sprays toward the water curtain plate 14, causing the water in the water tank 3 in the work area 2 to roll toward the water curtain plate 14, so that the paint mist flows into the water outlet 31 and then is filtered through the slag separator 34.

[0032] In this embodiment, an overflow port 35 is provided at the upper portion of the front side plate of the water tank 3, and a drain port 36 is provided at the lower portion of the front side plate of the water tank 3. The overflow port 35 is provided at the upper portion of the front side plate of the water tank 3 to prevent the water from overflowing due to the excessive water level in the water tank 3, and the drain port 36 is provided at the lower portion of the front side plate of the water tank 3 to drain the water in the water tank 3 when drainage is required.

[0033] In this embodiment, a water curtain paper inspection port 51 corresponding to the position of the filter water curtain paper 11 is provided on the front panel of the box body, so as to inspect the filter water curtain paper 11. As a further improvement of this embodiment, an observation port 52 corresponding to the position of the filter barrel 12 is also provided on the front panel of the box body, so as to observe the internal situation of the filter barrel 12. Furthermore, a slag cleaning port 53 is provided below the observation port 52 on the front panel of the box body, so as to facilitate the cleaning of waste slag. In specific implementation, the water curtain paper inspection port 51 and the slag cleaning port 53 are both openable openings, and the observation port 52 can be provided with transparent glass or acrylic plate, so that workers can observe the internal situation of the filter barrel 12 without being exposed to harmful materials such as paint mist.
