[0023] Reference Figure 1-4This utility model discloses a p-methylacetone crude mother liquor recovery device, comprising: a support plate 1 and auxiliary components. The support plate 1 has second mounting grooves 14 on both the front and rear sides of its lower surface. The second mounting grooves 14 provide a fixed mounting space for a hydraulic pump 15, ensuring its stable position. The hydraulic pump 15 is fixedly connected to the inner surface of the second mounting grooves 14. The hydraulic pump 15 serves as a power source, providing power for the extension and retraction of a hydraulic rod 16. The output end of the hydraulic pump 15 is fixedly connected to the hydraulic rod 16. Driven by the hydraulic pump 15, the hydraulic rod 16 extends and retracts, thereby driving a lower pressure plate 17 to rise and fall. The lower surface of the hydraulic rod 16 is fixedly connected to the lower pressure plate 17. The lower pressure plate 17, driven by the hydraulic rod 16, applies pressure to the object below and is a key component for performing operations such as squeezing. An auxiliary rod 18 is fixedly connected to the upper surface of the lower pressure plate 17. The auxiliary rod 18 plays a supporting and guiding role, ensuring the stability of the lower pressure plate 17 during the lifting process. A limit plate 19 is fixedly connected to the outer surface of the auxiliary rod 18. The limit plate 19 is used to limit the range of motion of the spring 21 and, together with the spring 21, plays a supporting and resetting role. The upper surface of the limit plate 19 abuts against the spring 21, and the upper surface of the spring 21 abuts against the fixing block 20. The fixing block 20 provides a support point for the spring 21, enabling it to stably play a supporting and constraining role.

[0024] The outer surfaces of spring 21 and auxiliary rod 18 are sleeved together, allowing them to work together to ensure the smooth operation of the lower pressure plate 17. The side wall of the fixing block 20 is fixedly connected to the support plate 1, securing the fixing block 20 firmly onto the support plate 1, thus ensuring the stability of the entire support and guide structure. The auxiliary rod 18 and the fixing block 20 are slidably connected, allowing the auxiliary rod 18 to slide freely within the fixing block 20, providing flexible and stable guidance for the lifting and lowering of the lower pressure plate 17. The auxiliary rods 18 are symmetrically arranged on the left and right sides of the upper surface of the lower pressure plate 17, ensuring that the lower pressure plate 17 experiences uniform force and smoother movement during lifting and lowering. The auxiliary components are located on the outer surface of the support plate 1 and include the first mounting groove 2, the fixing column 3, and the auxiliary components. The equipment comprises rollers 4, a recycling bin 5, a sealed lid 6, connecting columns 7, a rotating motor 8, a controller 11, a fixing plate 12, fixing bolts 13, and a handle 22. These components work together to achieve multiple functions, including recycling and control. The lower surface of the support plate 1 has four first mounting slots 2, providing mounting positions for the fixing columns 3 and ensuring their stability. The inner surfaces of the four first mounting slots 2 are fixedly connected to the fixing columns 3, which are used to fix the rollers 4, allowing them to rotate around their own axes. The outer surfaces of the fixing columns 3 are rotatably connected to the rollers 4, enabling the entire equipment to be easily moved, facilitating position adjustment and handling. Connecting columns 7 are fixedly connected to the side walls of both support plates 1, connecting the support plates. A connecting column 7 and a recycling tank 5 are connected, allowing the recycling tank 5 to rotate around it for easy opening and closing. The recycling tank 5 is rotatably connected to one end of the connecting column 7. The recycling tank 5 is used to collect crude p-methylacetone mother liquor and is the core storage component of the recycling equipment. Handles 22 are fixedly connected to both the left and right sides of the outer surface of the recycling tank 5, facilitating movement and handling by operators and improving operational convenience. A controller 11 is fixedly connected to the rear surface of the recycling tank 5. The controller 11 controls the operation of various components of the equipment, such as the hydraulic pump 15 and the rotary motor 8, to achieve automated operation. A sealing lid 6 is fixedly connected to the upper surface of the recycling tank 5, ensuring the internal sealing of the recycling tank 5 and preventing the mother liquor from evaporating or external impurities from entering. Two supports... A rotating motor 8 is fixedly connected to the side of plate 1 away from the connecting column 7. The rotating motor 8 serves as a power source, providing power for the rotation of the rotating column 9. The output end of the rotating motor 8 is fixedly connected to the rotating column 9. The rotating column 9 rotates under the drive of the rotating motor 8, thereby driving the connecting plate 10 and other components to move. A connecting plate 10 is fixedly connected to one end of the rotating column 9. The connecting plate 10 is used to connect the rotating column 9 and the fixed plate 12, and simultaneously performs operations such as squeezing the recycling box 5 during rotation. A fixed plate 12 is fixedly connected to the side wall of the connecting plate 10. The fixed plate 12 is used to install fixing bolts 13, which are used to connect to the recycling box 5, achieving a stable connection between the connecting plate 10 and the recycling box 5. Several fixing bolts 13 are threaded onto the rear surface of the fixed plate 12.The fixing bolts 13 securely connect the fixing plate 12 to the recycling bin 5, ensuring that the connecting plate 10 can stably apply force to the recycling bin 5 during rotation.

[0025] The first mounting slot 2 and the second mounting slot 14 are staggered. This arrangement makes reasonable use of the space of the support plate 1 and avoids mutual interference during component installation. The size of the roller 4 is adapted to the size of the first mounting slot 2, ensuring that the roller 4 can be stably installed in the first mounting slot 2 and can rotate flexibly. Each fixing bolt 13 extends into the interior of the recycling box 5, ensuring the firmness of the connection between the fixing plate 12 and the recycling box 5 and preventing the connecting plate 10 from loosening during rotation. The connecting columns 7 are symmetrically arranged on the left and right sides of the recycling box 5, ensuring that the recycling box 5 is evenly stressed during rotation and that opening and closing are more stable. The connecting plate 10 is located above the fixing block 20, so that the connecting plate 10 will not collide or interfere with the fixing block 20 and other components during rotation, ensuring the safe operation of the equipment. The size of the connecting plate 10 is adapted to the size of the recycling box 5, ensuring that the connecting plate 10 can effectively perform operations such as squeezing the recycling box 5 during rotation.

[0026] Working principle: First, the equipment is moved to a suitable position using rollers 4. The recycling bin 5 is opened using handle 22, and the sealed lid 6 is checked for integrity to ensure the recycling bin 5 is clean and well-sealed. Simultaneously, the controller 11 initializes and tests the hydraulic pump 15, rotating motor 8, and other equipment components. The crude p-methylacetone mother liquor to be recycled is poured into the recycling bin 5, and the sealed lid 6 is closed to ensure the recycling bin 5 is sealed, preventing the mother liquor from evaporating and external impurities from entering. The hydraulic pump 15 is started, driving the hydraulic rod 16 downwards, which in turn moves the lower pressure plate 17 downwards. The auxiliary rod 18 slides within the fixed block 20, acting as a guide. Simultaneously, the limit plate 19 cooperates with the spring 21 to ensure the lower pressure plate 17 presses down smoothly. 17. The mother liquor in the recovery tank 5 is squeezed to improve its recovery. The rotating motor 8 is started, which drives the rotating column 9 to rotate. The rotating column 9 then drives the connecting plate 10 to rotate. The connecting plate 10 is securely connected to the recovery tank 5 through the fixing plate 12 and fixing bolts 13. Thus, the recovery tank 5 is further squeezed or stirred during the rotation process to promote the recovery of the mother liquor. After the squeezing and rotation are completed, the hydraulic pump 15 and the rotating motor 8 are turned off by the controller 11. The hydraulic pump 15 stops working, and the hydraulic rod 16 drives the lower pressure plate 17 to rise and reset under the reset action of the spring 21. The recovery tank 5 is opened using the handle 22, and the recovered p-methylacetone crude mother liquor is taken out. The equipment is cleaned and inspected to prepare for the next use.
