Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a new technical solution: an ethyl acetate recovery and utilization device, including a distillation tank 1, an injection port 2 fixedly installed on the upper surface of the distillation tank 1, and a heating rod 17 fixedly installed in the inner wall of the distillation tank 1;

[0027] The distillation tank 1 is equipped with a distillation mechanism, which includes a C-shaped plate 3, a drive motor 4, a first bevel gear 5, a second bevel gear 6, a stirring rod 7, a sleeve 8, a third bevel gear 9, a fixing plate 10, a scraper 11, a conveying pipe 12, a filter 13, a condensate tank 14, a liquid storage tank 15, and a drain valve 16.

[0028] Furthermore, the C-shaped plate 3 is fixedly installed on the lower surface of the distillation tank 1, the drive motor 4 is fixedly installed on the left surface of the vertical plate of the C-shaped plate 3, and the first bevel gear 5 is fixedly sleeved on the outer surface of the output shaft of the drive motor 4.

[0029] Furthermore, the second bevel gear 6 is meshed with the outer surface of the first bevel gear 5, and the stirring rod 7 is fixedly installed on the inner surface of the second bevel gear 6. The lower end of the stirring rod 7 is rotatably connected to the upper surface of the C-shaped plate 3.

[0030] Furthermore, the sleeve 8 is rotatably sleeved on the outer surface of the stirring rod 7, and the third bevel gear 9 is fixedly sleeved on the outer surface of the sleeve 8, and the third bevel gear 9 is meshed with the outer surface of the first bevel gear 5.

[0031] Furthermore, the fixing plate 10 is fixedly sleeved on the outer surface of the sleeve 8, and the two scrapers 11 are fixedly installed on the upper surface of the fixing plate 10.

[0032] Furthermore, the inlet end of the conveying pipe 12 is fixedly installed on the upper surface of the distillation tank 1, and the filter 13 is fixedly installed on the outer surface of the conveying pipe 12.

[0033] Furthermore, the liquid storage tank 15 is fixedly installed on the outer surface of the delivery pipe 12, and the condensate tank 14 is disposed in the inner wall of the liquid storage tank 15;

[0034] The drain valve 16 is fixedly installed on the right surface of the storage tank 15;

[0035] When this ethyl acetate recovery and utilization device is in use, the heating rod 17 heats the ethyl acetate mixture in the distillation tank. The drive motor 4 is activated, and its operation outputs power to the first bevel gear 5 fixedly mounted on the outer surface of the output shaft, causing it to rotate. The first bevel gear 5 drives the second bevel gear 6, which is meshed with its outer surface, to rotate. The second bevel gear 6 then drives the stirring rod 7, which is fixedly mounted on its inner surface, to rotate. This stirs the ethyl acetate mixture in the distillation tank 1, ensuring uniform heating, improving distillation efficiency, and preventing localized overheating or undercooling. Simultaneously, the first bevel gear 5 drives the third bevel gear 9, which is meshed with its outer surface, to rotate.

The scraper 11 scrapes off the liquid droplets or impurities on the inner wall of the distillation tank 1 to prevent them from adhering to the tank wall and affecting the distillation effect. At this time, the ethyl acetate gas enters the filter 13 through the conveying pipe 12. The filter 13 filters the impurities in the ethyl acetate vapor to ensure that the ethyl acetate vapor entering the storage tank 15 is pure. At this time, the gas in the conveying pipe 12 is cooled by the condensate tank 14 to condense it into liquid ethyl acetate. At this time, the liquid ethyl acetate drips into the storage tank 15. The discharge of liquid ethyl acetate in the storage tank 15 can be controlled by the drain valve 16 for subsequent collection and treatment.

[0036] This ethyl acetate recovery and utilization device can stir the ethyl acetate mixture in the distillation tank 1 using the stirring rod 7, so that the mixture is heated evenly, improving distillation efficiency and preventing local overheating or undercooling. It can also use the scraper 11 to scrape off droplets or impurities on the inner wall of the distillation tank 1, preventing them from adhering to the tank wall and affecting the distillation effect, thereby improving the ethyl acetate recovery and utilization efficiency. This ethyl acetate recovery and utilization device filters impurities in ethyl acetate vapor through a filter, ensuring that the ethyl acetate vapor entering the storage tank 15 is pure, thereby improving the purity of the recovered ethyl acetate.
