[0031] According to one embodiment of the present application, a water curtain structure of a paint spray booth is provided. As shown in Figures 1 to 4 the water curtain structure of the paint spray booth comprises a water curtain plate assembly 1 and a spray assembly. The water curtain plate assembly 1 comprises a plurality of water curtain plates 11, the plurality of water curtain plates 11 are arranged in a vertical direction, and each water curtain plate 11 is provided with an air inlet 2 at a lower end thereof. The spray assembly comprises a plurality of spray members, and each water curtain plate 11 is provided with one spray member at an upper end thereof, and the spray member is adapted to spray medicinal water on the water curtain plate 11 to form a water curtain waterfall on the water curtain plate 11.
[0032] As shown in Figure 1 and Figure 2 in this example, the water curtain plate assembly 1 comprises a plurality of water curtain plates 11 arranged in a vertical direction, and each water curtain plate 11 is provided with an air inlet 2 at a lower end thereof for negative pressure absorption of paint mist waste gas, and each water curtain plate 11 is provided with one spray member at an upper end thereof, and the spray member is adapted to spray medicinal water on the water curtain plate 11 to form a water curtain waterfall on the water curtain plate 11, so as to efficiently and sufficiently absorb the paint mist waste gas in the air and effectively reduce the residual paint mist waste gas in the air.
[0033] In this example, the water curtain board 11 can form a water curtain waterfall by the spraying member, that is, the medicine water flows down along the surface of the water curtain board 11 from the upper end of the water curtain board 11, and can form a water curtain waterfall on the water curtain board 11. The paint mist particles sprayed on the continuous water curtain medicine water on the surface of the water curtain board 11 can be captured and removed by the liquid. Part of the paint mist exhaust gas can also be sucked into the inner cavity 52 of the cabinet 5 through the air inlet 2, and the paint mist exhaust gas can be further purified, that is, the air inlet 2 is communicated with the inner cavity 52, and the suction pipe of the exhaust assembly 6 is communicated with the inner cavity 52, so that the air inlet 2 can form a negative pressure through the exhaust assembly 6. Since the water curtain board 11 is provided with a plurality of water curtain boards, a plurality of air inlets 2 can be formed in the vertical direction, so that the paint mist exhaust gas in the air can be more efficiently sucked into the inner cavity 52 of the cabinet 5.
[0034] In this example, the water curtain board 11 can be a plate structure made of stainless steel or aluminum alloy, and the skilled person in the art can determine according to the actual situation, which is not limited here.
[0035] In one example, as shown in Figure 1 and Figure 4 , the water curtain board 11 is in an arc-shaped curved surface structure. For example, the water curtain board 11 is in an outwardly convex arc-shaped structure, so as to increase the area of the water curtain board 11 and increase the area of the water curtain waterfall in contact with the air, which is beneficial to improve the absorption effect of the paint mist exhaust gas.
[0036] Alternatively, the water curtain board 11 can also be in a wave-shaped structure, and the skilled person in the art can determine according to the actual situation, which is not limited here.
[0037] In one example, as shown in Figure 1 and Figure 2 , the lower end of the water curtain board 11 is provided with a filter part 111, and the filter part 111 has a bypass opening, and the bypass opening forms the air inlet 2.
[0038] As shown in Figure 1 and Figure 2 , in this example, the lower end of each water curtain board 11 is provided with a filter part 111, and the filter part 111 can filter larger particle impurities and the like, so as to avoid large particles and large volume impurities from entering the inner cavity 52, so as to easily enter the suction pipe of the exhaust assembly 6 and easily block the suction pipe.
[0039] For example, as shown in Figure 1 and Figure 2As shown, the filter part 111 is a sawtooth structure arranged in the horizontal direction. The lower end of the water curtain plate 11 is provided with a sawtooth structure in the width direction, which can form the filter part 111, that is, the gap between two sawteeth can form the air inlet 2. By arranging the filter part 111 with a sawtooth structure at the lower end of the water curtain plate 11, the processing is simple, and additional filter structure can not be arranged, which is beneficial to reduce the number of components of the overall structure. Among them, the sawteeth can be rectangular teeth or triangular teeth. Alternatively, the filter part 111 can also be other structures, for example, a filter screen structure, etc., which can be determined by the person skilled in the art according to the actual situation, and is not specifically limited here.
[0040] In one example, as shown in Figure 1 and Figure 4 , the water curtain plates 11 are arranged at intervals, and the heights of the two water curtain plates 11 are the same.
[0041] As shown in Figure 1 and Figure 4 , in this example, the water curtain assembly 1 can be provided with two water curtain plates 11, and the two water curtain plates 11 are arranged at intervals in the vertical direction. The gap between the upper water curtain plate 12 and the lower water curtain plate 13 forms the air inlet 2, which communicates with the inner cavity 52. The lower end of the lower water curtain plate 13 is also provided with the air inlet 2, which also communicates with the inner cavity 52.
[0042] Among them, the heights of the two water curtain plates 11 are the same, which can make the air inlet 2 between the upper water curtain plate 12 and the lower water curtain plate 13 located in the middle position.
[0043] Of course, the water curtain assembly 1 can also be provided with more water curtain plates 11, for example, three, four or five, etc., which can be determined by the person skilled in the art according to the actual situation, and is not specifically limited here.
[0044] In one example, as shown in Figure 1 , the spray member includes a spray pipe 32, which is arranged above the water curtain plate 11 in the width direction of the water curtain plate 11.
[0045] As shown in Figure 1 , in this example, a plurality of spray holes are arranged on the spray pipe 32 in the length direction, the spray pipe 32 is arranged along the upper end of the water curtain plate 11 and in the width direction of the water curtain plate 11. Through the spray holes of the spray pipe 32, the medicinal water can be sprayed to the surface of the water curtain plate 11, and a water curtain waterfall can be formed on the surface of the water curtain plate 11.
[0046] Among them, one end of the spray pipe 32 is communicated with the water pump 7 through the water suction pipe 71, and the water pump 7 can suck the medicinal water into the spray pipe 32.
[0047] In one example, as shown in Figure 1 and Figure 4 As shown in

Among them, the side of the first water tank 31 is a medicine water overflow side, and the side of the first water tank 31 opposite to the medicine water overflow side is higher in height, so that the medicine water in the first water tank 31 can smoothly overflow from the medicine water overflow side. The width of the medicine water overflow side corresponds to the width of the water curtain plate 11, for example, the width of the medicine water overflow side is the same as the width of the water curtain plate 11. Thus, the medicine water that can overflow can cover the water curtain plate 11.
[0049] In one example, the filtering part 111 of the water curtain plate 11 on the upper side can partially extend into the first water tank 31 on the lower side. The lower end of the water curtain plate 11 is provided with the filtering part 111, which can partially extend into the corresponding first water tank 31 on the lower side, that is, when the first water tank 31 is filled with medicine water, the filtering part 111 can be partially immersed in the medicine water. Thus, large particles and large volumes of impurities can be filtered in the first water tank 31. For example, the filtering part 111 is a sawtooth structure provided at the lower end of the water curtain plate 11, which can partially extend into the first water tank 31.
