[0028] like Figure 3As shown, the stirring mechanism includes a turntable 13, a plurality of stirring plates 14 and a drive motor 15. The turntable 13 is rotatably mounted in the water tank 8. The plurality of stirring plates 14 are fixedly mounted on the top of the turntable 13. The plurality of stirring plates 14 are evenly distributed in a ring shape. The drive motor 15 is fixedly mounted on the bottom of the water tank 8. The output shaft of the drive motor 15 is fixedly connected to the turntable 13.

[0029] By providing the stirring mechanism, the water in the water tank 8 can be stirred, so that when the refrigeration device 12 cools the water in the water tank 8, the temperature of the water in the water tank 8 is kept consistent.

[0030] like Figure 4 As shown, a connecting pipe 16 is installed through the partition 2, and a fixed shaft 17 is rotatably installed in the connecting pipe 16. A conical block 18 is fixedly sleeved on the fixed shaft 17, and a plurality of inclined plates 19 are fixedly installed on the conical block 18;

[0031] By providing the connecting pipe 16 , the fixed shaft 17 , the conical block 18 and the inclined plate 19 , the exhaust gas in the cooling chamber 4 can be rotated when entering the filter chamber 3 , so that the exhaust gas is evenly distributed in the filter chamber 3 .

[0038] The working principle of the solvent recovery buffer box provided by the utility model is as follows:

[0039] Step 1: When in use, the exhaust gas enters the cooling chamber 4 through the air inlet pipe 5, and the refrigeration device 12 is started. The refrigeration device 12 can cool the water in the water tank 8, and the drive motor 15 is started. The drive motor 15 drives the turntable 13 and the stirring plate 14 to rotate, stirring the water, so that the temperature of the water in the water tank 8 is kept consistent. At this time, the exhaust gas in the cooling chamber 4 gradually moves downward between the multiple guide plates 11, and the heat exchange rod 10 can absorb the temperature in the exhaust gas and transfer it to the heat exchange plate 9 to exchange heat with the water in the water tank 8, thereby reducing the temperature of the exhaust gas. After the solvent in the exhaust gas contacts the heat exchange rod 10, the solvent will stay on the heat exchange rod 10 when it is cooled, and the exhaust gas can be easily recovered preliminarily;

[0040] The second step: the exhaust gas enters the filter chamber 3 through the cooling chamber 4. Under the action of the exhaust gas flow, the fixed shaft 17, the conical block 18 and the inclined plate 19 rotate, thereby rotating the exhaust gas and making the exhaust gas evenly distributed in the filter chamber 3. Then the filter plate 7 filters the solvent in the exhaust gas again to further recover the exhaust gas.
