[0028] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0030] Reference Figures 1 to 5 As shown, a high-pressure cyclone water curtain cabinet includes a water storage tank 1 and a main cabinet 2. The main cabinet 2 is mounted on the water storage tank 1 and has a water curtain structure 3. The lower part of the water curtain structure 3 has an air inlet 4. The main cabinet 2 has a cyclone structure 5 inside and an air outlet 6 at the top. The air inlet 4, the cyclone structure 5 and the air outlet 6 are connected in sequence. The water storage tank 1 is equipped with a protective frame 7, which is connected to the main cabinet 2. The protective frame 7 encloses a working space on the water storage tank 1, and the working space is connected to the air inlet 4.

[0031] This application enlarges the water storage tank 1, allowing a protective frame 7 to be installed on it. The protective frame 7 and the water storage tank 1 form a working space where workers can perform processes such as painting or sanding. The generated particulate matter mixed with air can be directly drawn away by the air inlet 4, reducing exhaust gas leakage. At the same time, some particulate matter that is not drawn away will fall into the water storage tank 1, which can be disposed of together when cleaning the water storage tank 1 later, reducing the amount of cleaning required after the operation.

[0032] In this embodiment, the main cabinet 2 is provided with a lower chamber 21 and an upper chamber 22. The air inlet 4 is connected to the lower chamber 21. The lower chamber 21 is connected to the water storage tank 1. The cyclone structure 5 connects the upper chamber 22 and the lower chamber 21. The upper chamber 22 is connected to the air outlet 6.

[0033] The exhaust port 6 is connected to the ventilation system, which in turn creates negative pressure at the air inlet 4, allowing for air extraction. The water curtain structure 3 generates a water curtain, and as the exhaust gas passes through the air inlet 4, most of the particulate matter is removed by the water curtain. The exhaust gas then enters the lower chamber 21 and passes through the cyclone structure 5, where it fully combines with the water mist, thus removing particulate matter. The clean gas then enters the upper chamber 22 and is discharged through the exhaust port 6.

[0034] In this embodiment, the water curtain structure 3 is located on the side of the main cabinet 2 near the protective frame 7. The water curtain structure 3 includes an overflow channel 31, a water curtain plate 32, and a guide plate 33.

[0035] The water curtain plate 32 is connected to the overflow trough 31 so that the water in the overflow trough 31 can flow onto the water curtain plate 32 to form a water curtain.

[0036] The guide plate 33 is located below the water curtain plate 32, and the lower end of the water curtain plate 32 and the guide plate 33 form an air inlet 4. The water curtain can pass through the air inlet 4, and the exhaust gas will be washed by the water curtain when it passes through the air inlet 4. Moreover, the bottom of the water curtain plate 32 is serrated, which can disperse the water curtain and make the water curtain discontinuous, ensuring that the exhaust gas can pass through the air inlet 4, while also dispersing the exhaust gas.

[0037] There is a gap between the guide plate 33 and the bottom of the water storage tank 1, so that the guide plate 33 will not obstruct the flow of water in the water storage tank 1.

[0038] In this embodiment, the guide plate 33 bends upward in the direction away from the protective frame 7, which can guide the exhaust gas to the upper part of the lower chamber 21 and allow the exhaust gas to enter the cyclone structure 5.

[0039] In this embodiment, the cyclone structure 5 includes a cyclone barrel 51, and a cyclone separator 52 is provided in the cyclone barrel 51. When the exhaust gas passes through the cyclone barrel 51, particulate matter is separated based on the cyclone effect.

[0040] In this embodiment, the upper chamber 22 is provided with a defogging structure 8, and a spray module is provided between the defogging structure 8 and the cyclone structure 5. The spray module sprays water into the cyclone barrel 51, and water mist is formed under the action of the cyclone separator 52. The separated particles will combine with the water mist and fall into the water storage tank 1.

[0041] Specifically, it also includes a water circulation structure. The spray module includes a spray pipe installed in the upper chamber 22, and an overflow tank 31 connected to a water supply pipe. The water in the water storage tank 1 is pumped to the spray pipe and the water supply pipe by a water pump, thereby recycling the water in the water storage tank 1. Of course, a filter device can be installed at the input end of the water pump, and the water in the water storage tank 1 is pumped out after passing through the filter device.

[0042] In this embodiment, the defogging structure 8 includes a defogging box, which is equipped with defogging filler. When the gas passes through the defogging box, the water mist inside is blocked.

[0043] In this embodiment, the inner wall of the bottom of the cyclone barrel 51 is provided with an annular baffle 511, the cyclone separator 52 is placed on the annular baffle 511, the outer periphery of the cyclone barrel 51 is provided with an opening 512, and a cover 53 is detachably provided on the cyclone barrel 51, the cover 53 covers the opening 512, and the cyclone separator 52 is lower than the opening 512.

[0044] The size of the opening 512 is adapted to the size of the hydrocyclone 52, ensuring that the hydrocyclone 52 can enter and exit the opening 512. The hydrocyclone 52 is not fixed. During maintenance, the hydrocyclone 52 can be directly removed through the opening 512 and put back after maintenance, without needing to disassemble the main cabinet 2.

[0045] In this embodiment, the cover 53 is provided with an observation window. When the cover 53 is closed, the observation window can be used normally, making it convenient to observe the situation inside the cyclone barrel 51.

[0046] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
