Technical Field

[0001] This utility model relates to the field of environmental protection technology in chemical production, specifically a device for recovering residual liquid from diacetone alcohol production. Background Technology

[0002] Diacetone alcohol is an important fine chemical product with wide applications in industries such as coatings, inks, and pharmaceuticals. During the production of diacetone alcohol, a certain amount of residual liquid is generated. This residual liquid typically contains unreacted raw materials, byproducts, and diacetone alcohol. Directly discharging this residual liquid not only wastes resources but also pollutes the environment. However, existing residual liquid recovery devices have some shortcomings, such as:

[0003] Currently, existing diacetone alcohol production residue recovery devices do not completely separate impurities from the residue during use, resulting in low purity of the recovered diacetone alcohol and limiting their application. Alternatively, existing diacetone alcohol production residue recovery devices consume a lot of energy during the recovery process, increasing production costs and limiting their application. Therefore, it is necessary to improve the diacetone alcohol production residue recovery device to solve the above problems. Utility Model Content

[0022] Example:

[0023] Please see Figure 1-4 This utility model provides a technical solution: a diacetone alcohol production residue recovery device, including a recovery component 1, a filter component 4 placed in the upper part of the recovery component 1, and the filter component 4 includes a primary filter element 41, a secondary filter element 42 and a high-grade filter element 43, which are stacked sequentially from top to bottom, and a heating component 2 is sleeved and connected to the outside of the recovery component 1; the heating component 2 includes a heating cylinder 21 and a rubber sealing ring 22, and the rubber sealing ring 22 is fixedly connected to the inner peripheral surface of the bottom of the heating cylinder 21, an oil inlet 23 is fixedly connected to the upper outer side of the peripheral surface of the heating cylinder 21, and an oil outlet 24 is fixedly connected to one side of the bottom surface of the heating cylinder 21.

[0024] Working Principle: When recovering residual liquid from diacetone alcohol production, the residual liquid is fed into the recovery tank 11 via an external residual liquid conveying pipe connected to the inlet pipe 19. The residual liquid then passes sequentially through the primary filter 41, intermediate filter 42, and advanced filter 43, where impurities of different sizes are progressively filtered and trapped. The motor 31 drives the stirring shaft 32 and the spiral blades 33 to rotate, ensuring thorough mixing of the residual liquid within the tank. A heat transfer oil inlet pipe connected to the oil inlet 23 allows heat transfer oil to be added to the heating cylinder 21, heating the residual liquid in the recovery tank 11. An external control terminal opens the solenoid valve 15, allowing the filtered recovered liquid to be discharged through the drain pipe 14 for further processing such as distillation. As filtration progresses, impurities gradually accumulate on the filter screen. When it is necessary to remove impurities, simply open the tank lid 17 and remove the filter assembly 4 for cleaning and replacement.

[0025] Among them, such as Figure 2 As shown, a stirring assembly 3 is fastened to the middle of the recycling assembly 1, and the stirring assembly 3 includes a motor 31 and a stirring shaft 32. The stirring shaft 32 is fastened to the end of the output shaft of the motor 31, and a spiral blade 33 is fixedly connected to the circumferential surface of the stirring shaft 32. Specifically, the rotation of the motor 31 will drive the stirring shaft 32 and the spiral blade 33 to rotate.

[0026] Among them, such as Figure 3 , 4 As shown, the recycling assembly 1 includes a recycling tank 11 and support legs 12. The support legs 12 are evenly and fixedly connected to the bottom edge of the recycling tank 11, and a gasket 13 is fixedly connected to the bottom surface of the support legs 12. A fixing ring 16 is fixedly connected to the upper part of the inner wall of the recycling tank 11, and a liquid drain pipe 14 is fixedly connected to the middle of the bottom surface of the recycling tank 11. A solenoid valve 15 is fixedly connected to the middle of one side of the circumferential surface of the liquid drain pipe 14. A tank cover 17 is placed on the top of the recycling tank 11, and handles 18 are symmetrically fixedly connected to both sides of the upper surface of the tank cover 17. A liquid inlet pipe 19 is fixedly connected to one side of the upper part of the tank cover 17. Specifically, by applying a vertical upward force to the handles 18, the tank cover 17 can be lifted.
