The cyclone cylinder 2 is installed on the cabinet body 1 and located on the upper side of the first cavity 11, and the cyclone cylinder 2 is connected to the first cavity 11. The first spray pipe 3 is disposed in the first cavity 11.

[0033] In this example, the cabinet 1 is provided with a first cavity 11, and the first cavity 11 is provided with a spray pipe, which can spray liquid medicine in the first cavity 11. The paint mist exhaust gas enters the first cavity 11 from the air inlet 7, can adsorb the paint mist particles in the first cavity 11, and then further adsorb in the cyclone cylinder 2, so as to more fully adsorb the paint mist particles in the gas.

[0034] In this example, the cyclone cylinder 2 is installed on the cabinet 1 and located on the upper side of the first cavity 11. The upper and lower ends of the cyclone cylinder 2 are open. The lower end of the cyclone cylinder 2 is communicated with the first cavity 11. The paint mist exhaust gas enters the first cavity 11 from the air inlet 7, and then enters the cyclone cylinder 2. The upper end of the cyclone cylinder 2 can be communicated with the exhaust pipe of the exhaust assembly 9. The exhaust assembly 9 is installed on the upper end of the cabinet 1. The exhaust assembly 9 includes a fan and an exhaust pipe. The fan is embeddedly connected to the upper surface of the cabinet 1.

The upper end of the cyclone cylinder 2 is further provided with a second spray pipe 21. The second spray pipe 21 is communicated with the water pump 10. The water pump 10 delivers liquid medicine to the second spray pipe 21. The second spray pipe 21 can spray liquid medicine into the cyclone cylinder 2 and flow out of the cyclone cylinder 2 from top to bottom. The paint mist exhaust gas enters the inside of the cyclone cylinder 2 from the first cavity 11. The paint mist exhaust gas rotates and moves upward in the cyclone cylinder 2. The gas and liquid collide and mix in the cyclone cylinder 2 to form a mixture of gaseous, liquid and solid states. Part of the paint mist particles is separated by the cyclone centrifugal force and thrown to the wall of the cyclone cylinder 2. Part of the paint mist particles is captured by the liquid medicine in the cyclone cylinder 2.

[0035] The cyclone cylinder 2 can be provided with multiple cyclone cylinders to efficiently remove paint mist particles. For example, the cyclone cylinder 2 can be provided with two, three or four cyclone cylinders, etc. The skilled person can determine the number of cyclone cylinders according to the actual situation, which is not limited herein.

[0036] In this example, the first spray pipe 3 is communicated with the water pump 10. The water pump 10 delivers liquid medicine to the first spray pipe 3. The two ends of the first spray pipe 3 can be respectively connected to the inner walls on the opposite sides of the first cavity 11. The first spray pipe 3 can spray liquid medicine in the first cavity 11, so as to remove the paint mist particles in the air.

[0037] In one example, the first spray pipe 3 is provided with multiple spray holes along the length direction and the circumferential direction. The first spray pipe 3 can be a cylindrical pipe. The first spray pipe 3 is provided with multiple spray holes along the circumferential direction and further provided with multiple spray holes along the length direction. Thus, the first spray pipe 3 can spray in all directions in the first cavity 11 to improve the removal effect of the paint mist particles.

[0038] The number and size of the spray holes can be determined by the skilled person according to the actual situation, which is not limited herein.

[0039] In one example, as shown in Figures 1 to 3 The cyclone water curtain paint spray booth further comprises a water curtain plate 4, which is installed on the cabinet 1, and is a side wall of the first cavity 11. The lower end of the water curtain plate 4 forms the air inlet 7.

[0040] As shown in Figures 1 to 3 In this example, the liquid medicine can flow from top to bottom along the water curtain plate 4, so as to form a water curtain waterfall on the outer wall of the water curtain plate 4, and efficiently and fully absorb the paint mist waste gas in the air, effectively reducing the residual paint mist waste gas in the air. The water curtain plate 4 can be a plate structure made of stainless steel or aluminum alloy, etc., which can be determined by the actual situation, and is not specifically limited here.

[0041] In this example, the water curtain plate 4 is a side wall of the first cavity 11, that is, the inner side of the water curtain plate 4 is the inner wall of the first cavity 11, and the outer side of the water curtain plate 4 is suitable for liquid medicine flow. The lower end of the water curtain plate 4 has the air inlet 7, and the first cavity 11 is in communication with the outside through the air inlet 7. By taking the water curtain plate 4 as the side wall of the first cavity 11, the side wall of the first cavity 11 does not need to be additionally arranged, which is beneficial to save the weight and volume of the whole paint spray booth.

[0042] In this example, the upper end of the water curtain plate 4 is provided with a second water groove 41, and the third spray pipe 42 can also be in communication with the water pump 10. The liquid medicine can be injected into the second water groove 41 through the third spray pipe 42, and the liquid medicine can overflow from the second water groove 41 and flow along the water curtain plate 4, and form a water curtain waterfall on the water curtain plate 4.

[0043] As shown in Figure 1 The second water groove 41 can be connected to the cabinet 1, and the second water groove 41 is located at the upper end of the water curtain plate 4. The third spray pipe 42 injects the liquid medicine into the second water groove 41, and the liquid medicine in the second water groove 41 can overflow after being filled, and flow downward along the water curtain plate 4 from the upper end of the water curtain plate 4. One side of the second water groove 41 is a liquid medicine overflow side, and the side of the second water groove 41 opposite to the liquid medicine overflow side is higher in height, so that the liquid medicine in the second water groove 41 can smoothly overflow from the liquid medicine overflow side. The width of the liquid medicine overflow side corresponds to the width of the water curtain plate 4, for example, the width of the liquid medicine overflow side is the same as the width of the water curtain plate 4. Thus, the overflowing liquid medicine can uniformly cover the water curtain plate 4.

[0044] In one example, as shown in Figures 1 to 3 The cyclone water curtain paint spray booth further comprises a guide plate 5, which is installed on the inner wall of the first cavity 11 and located above the air inlet 7.

[0045] As shown in Figures 1 to 3As shown, a guide plate 5 is also installed on the inner wall of the first cavity 11. The guide plate 5 is located above the air inlet 7. The guide plate 5 can divide the first cavity 11 to form a guide channel, so that the paint mist exhaust gas can flow along the preset channel, so that the first spray pipe 3 can remove paint mist particles in the paint mist exhaust gas more efficiently.

[0046] like Figure 3 As shown, in this example, the guide plate 5 can be an arc-shaped plate, formed by connecting multiple straight plates sequentially at a certain angle, thus creating a structure similar to an arc-shaped plate. For example, the straight plates can be fixedly connected by welding, riveting, or screwing. The guide plate 5 can be connected to the inner wall of the first cavity 11 by screwing, riveting, or welding.

[0047] The guide plate 5 can be made of stainless steel or aluminum alloy, etc., and those skilled in the art can decide according to the actual situation, without making specific limitations here.

[0048] In one example, such as Figure 3 As shown, the first cavity 11 has a first inner wall 111 on the side opposite to the water curtain plate 4, the guide plate 5 is installed on the water curtain plate 4, there is a gap between the guide plate 5 and the first inner wall 111, and the first spray pipe 3 corresponds to the gap.

[0049] like Figure 3 As shown, in this example, the side opposite to the water curtain plate 4 is the first inner wall 111. One end of the guide plate 5 is installed inside the water curtain plate 4, and the other end of the guide plate 5 extends toward the first inner wall 111, with a gap between it and the first inner wall 111. The lower end of the water curtain plate 4 has an air inlet 7. The position of the first spray pipe 3 corresponds to the gap. For example, the first spray pipe 3 can be located inside the gap. In the vertical direction, the first spray pipe 3 is located above the guide plate 5.
