When the driving ring 109 drives the cleaning plate 2 1012 to rotate, the cleaning plate 2 1012 drives the vertical lever 202 to rotate. After the vertical lever 202 rotates, it drives the force-bearing rod 201 to move, so that the force-bearing rod 201 drives the collecting ball 2 to move. Under the action of the spring, the collecting ball 2 vibrates to shake off the moisture attached to it and drops it to the inside of the stirring tank body 1, thereby preventing the waste gas from carrying more moisture when it flows out, causing the problem of moisture reduction during the production of photocuring coatings, thereby ensuring the quality of the photocuring coatings.

[0033] Embodiment 3, on the basis of embodiment 1, a jet hood 3 is installed on the output end of the driving cylinder at the top of the air guide hood 103; the jet hood 3 is installed on the collecting hood 102, and the bottom of the jet hood 3 is flush with the inner side of the collecting hood 102; a stretching tube 301 is installed on the top of the air guide hood 3; the top of the stretching tube 301 is connected to the bottom of the air guide tube 302; the top of the air guide tube 302 passes through the sealed kettle cover 101 and is connected to the air pump at the top thereof, and when the exhaust gas generated in the stirring kettle is collected, when the sealed kettle cover 101 needs to be opened, the air guide hood The driving cylinder at the top of 103 drives the spray hood 3 to move downward, and the spray hood 3 pulls the stretch tube 301 to change, so that the spray hood 3 is in a suitable position, and the air pump on the top of the sealed kettle cover 101 works, and the clean air flow from the outside flows downward through the guide tube 302 and the stretch tube 301, and the air flow flows through the spray hood 3 to the inside of the stirring kettle body 1, so that the air flow dilutes the residual exhaust gas, and the collecting hood 102 absorbs the exhaust gas again to reduce the concentration of the exhaust gas, thereby preventing the residual exhaust gas from flowing out and polluting the surrounding air when the sealed kettle cover 101 is opened.

[0034] The working principle of this embodiment is as follows: when in use, the position of the collecting hood 102 is adjusted according to the height of the material inside the stirring kettle body 1, the rotating driving plate 106 is rotated to drive the rotating rod 107 to move downward, and the rotating rod 107 drives the collecting hood 102 to move to a suitable height inside the stirring kettle body 1, and the suction pump on the air outlet pipe 105 works, and the exhaust gas in the stirring kettle body 1 flows outward through the collecting hood 102, and the exhaust gas flows into the exhaust gas treatment equipment through the telescopic tube 104 and the air outlet pipe 105. At the same time, the servo motor on the guide hood 103 drives the driving ring 109 to rotate on the inner side of the guide hood 103, and the driving ring 109 drives the guide ring 1010 to rotate along the guide groove 108 through the cleaning plate 1011, and the cleaning plate 1011 cleans the inner side of the collecting hood 102, and the cleaning plate The second 1012 cleans the inner side of the guide cover 103 to reduce the splashing materials that block the collecting cover 102 and affect the flow of exhaust gas. The condenser outside the guide cover 103 makes the temperature of the collecting ball 2 lower. When the exhaust gas flows upward, the moisture carried in the airflow forms water droplets after being cooled and adheres to the collecting ball 2. The cleaning plate 1012 drives the vertical rod 202 to rotate and then drives the force rod 201 to move. The force rod 201 drives the collecting ball 2 to vibrate and shake off the moisture attached to it. When it is necessary to open the sealed kettle cover 101, the air pump on the top of the sealed kettle cover 101 starts to work, and the clean airflow flows downward through the guide pipe 302 and the stretching tube 301, and then flows to the stirring kettle body 1 through the spray cover 3 to dilute the residual exhaust gas. The collecting cover 102 absorbs the exhaust gas again, and the concentration of the exhaust gas is reduced.
