[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Reference Figure 1 , Figure 2 This utility model provides an embodiment of an apparatus for preparing activated carbon from liquor lees, comprising a carbonization chamber 1 and a combustion chamber 3. The combustion chamber 3 is located at the bottom of the carbonization chamber 1 and partially surrounds the lower half of the carbonization chamber 1. The outer layer of the combustion chamber 3 is wrapped with heat-insulating cotton, which can concentrate the heat generated by combustion onto the carbonization chamber 1, reduce heat loss, and improve heat utilization efficiency. The carbonization chamber 1 is used to provide a sealed space for the carbonization reaction of liquor lees, isolating it from the outside air and preventing the material from oxidizing. A second cover plate 4 is hinged to the bottom of the front surface of the combustion chamber 3. The edge of the second cover plate 4 is provided with a high-temperature resistant sealing strip. A handle is provided above the front surface of the second cover plate 4, which is convenient for operators to open the second cover plate 4 to add fuel or clean ash into the combustion chamber 3.

[0033] Reference Figure 1 , Figure 2 The carbonization chamber 1 is hinged to the left rear end exposed to the outside with a first cover plate 2. The edge of the first cover plate 2 is also provided with a high-temperature resistant sealing strip. An observation window is opened on the upper left surface of the first cover plate 2 and a handle is provided in front of it. The observation window allows the operator to observe the carbonization status of the liquor lees inside the carbonization chamber 1 in real time, such as changes in material color and whether there is clumping. The handle makes it easy for the operator to open the first cover plate 2 to remove the carbonized material or to maintain and clean the inside of the carbonization chamber 1. A feed pipe 5 is provided at the top center of the carbonization chamber 1. A rotating component is provided inside the carbonization chamber 1, which can drive the internal material to rotate slowly, so that the material is heated evenly.

[0034] Reference Figure 3 , Figure 4 The rotating assembly includes a storage mesh frame 16 and a rotating shaft 12. The storage mesh frame 16 is a cuboid metal mesh structure used to hold the liquor lees. The mesh design allows heat to penetrate evenly into the material, while facilitating the smooth discharge of pyrolysis gases generated during carbonization. A cylinder 17 is rotatably connected to the upper center of the front and rear outer walls of the storage mesh frame 16. A fixing block 18 is rotatably connected to the other end of the cylinder 17, allowing for flexible rotation between the storage mesh frame 16 and the fixing block 18.

[0035] Reference Figure 3 , Figure 4The front end of the rotating shaft 12 penetrates the front wall of the carbonization chamber 1 and is fixedly connected to a drive assembly. A high-temperature resistant sealed bearing is installed at the penetration point to prevent the leakage of hot gas inside the carbonization chamber 1 and the entry of external air. Its rear end is rotatably connected to the rear inner wall of the carbonization chamber 1. The circumferential surfaces of the rotating shaft 12 near the front and rear inner walls of the carbonization chamber 1 are fixedly connected to U-shaped blocks 14 by four evenly distributed connecting rods 13. The openings of the U-shaped blocks 14 all face outward. The U-shaped blocks 14 are snapped onto the surface of the fixed block 18 by a snap-fit ​​assembly. The snap-fit ​​assembly enables quick connection and disassembly of the U-shaped blocks 14 and the fixed block 18, facilitating the removal, replacement and maintenance of the storage mesh frame 16.

[0036] Reference Figure 1 , Figure 2 A protective shell 6 is provided on the outside of the drive assembly. The protective shell 6 is used to protect the drive assembly and prevent dust and impurities from entering and affecting the operation. At the same time, it avoids the operator from accidentally touching the moving parts and causing safety accidents. The rear side of the protective shell 6 is connected to the front surface of the carbonized chamber 1 by bolts, which facilitates the disassembly and installation of the protective shell 6. The drive assembly includes a drive gear 9. A fixing plate 7 is fixedly connected to the right outer wall of the carbonized chamber 1. A motor 8 is provided on the upper surface of the fixing plate 7.

[0037] Reference Figure 2 The output shaft of motor 8 passes through the inner wall of protective shell 6 and is fixedly connected to the center of drive gear 9. A sealing ring is provided at the point where it passes through the inner wall of protective shell 6 to prevent dust from entering. Drive gear 9 is connected to driven gear 11 through chain 10. The number of teeth of drive gear 9 is less than the number of teeth of driven gear 11. The speed reduction is achieved by the difference in the number of teeth, so that the rotating shaft 12 can obtain a suitable speed. The rear center of driven gear 11 is fixedly connected to the front end of rotating shaft 12.

[0038] Reference Figure 5 The locking assembly includes a spring 21 with good elasticity and fatigue resistance. A circular groove 19 is provided on the inner side wall of the U-shaped block 14, and an inclined surface is provided between its inner wall and the bottom inner wall. A circular block 20 is slidably connected to the inner wall of the circular groove 19. A circular rod 22 is fixedly connected to one end of the circular block 20 near the bottom of the inner wall of the circular groove 19. The other end of the circular rod 22 passes through the outer wall of the U-shaped block 14 and is hinged to a lever 15. The operator can move the circular rod 22 and the circular block 20 by moving the lever 15 to unlock the locking assembly.

[0039] Reference Figure 3 , Figure 4 , Figure 5 The fixed block 18 has a limiting hole on its side that matches the round block 20. The spring 21 is sleeved on the circumferential surface of the round rod 22 and elastically connects the round block 20 to the bottom of the inner wall of the round groove 19. When the fixed block 18 moves into the U-shaped block 14, the round block 20 is inserted into the limiting hole under the action of the spring 21, thus realizing the fixed connection between the fixed block 18 and the U-shaped block 14.

[0040] Reference Figure 3 , Figure 4 , Figure 5 The diameter of the round block 20 is larger than that of the round rod 22, which can prevent the round block 20 from falling out of the round groove 19 and ensure the stability of the snap-fit ​​assembly structure. The shape and size of the fixing block 18 are adapted to the inner wall of the U-shaped block 14. The side surface of the fixing block 18 is provided with an inclined surface adapted to the inclined surface of the inner wall of the U-shaped block 14. During the process of the fixing block 18 sliding into the U-shaped block 14, the inclined surface of the fixing block 18 pushes the round block 20 to compress the spring 21 and retract into the round groove 19, so that the fixing block 18 can be installed smoothly without manual operation.

[0041] Working principle: When in use, the operator first opens the second cover plate 4, adds fuel into the combustion chamber 3, closes the second cover plate 4 and ignites the fuel, so that the heat generated by combustion is concentrated on the carbonization chamber 1.

[0042] Once the temperature inside the carbonization chamber 1 reaches the initial temperature required for carbonizing the baijiu lees, the operator conveys the pre-treated baijiu lees material through the feed pipe 5 at the top center of the carbonization chamber 1 to the storage mesh frame 16 of the rotating assembly inside the carbonization chamber 1. Then, the motor 8 on the upper surface of the fixing plate 7 on the right outer wall of the carbonization chamber 1 is started. The output shaft of the motor 8 drives the drive gear 9 to rotate. Since the drive gear 9 is connected to the driven gear 11 via the chain 10, the rotation of the driven gear 11 simultaneously drives the rotating shaft 12 to rotate. When the rotating shaft 12 rotates, it drives the fixing block 18 to rotate through the connecting rod 13, U-shaped block 14, and snap-fit ​​assembly, ultimately causing the storage mesh frame 16 and the baijiu lees material inside to rotate slowly, ensuring that the material is heated evenly during the carbonization process. During the carbonization reaction, the operator can observe the carbonization status of the baijiu lees inside the carbonization chamber 1 in real time through the observation window above the left surface of the first cover plate 2 at the left rear end of the carbonization chamber 1.

[0043] After the carbonization reaction is completed, the motor 8 and the fuel in the combustion chamber 3 are turned off. After the temperature in the carbonization chamber 1 drops to a safe range, the operator opens the first cover plate 2 by the handle, and then pushes the outer paddle 15 of the U-shaped block 14 upward, which moves the round rod 22 and the round block 20 in the round groove 19 to the bottom of the inner wall of the round groove 19, compressing the spring 21 sleeved on the circumferential surface of the round rod 22, so that the round block 20 is dislodged from the limiting round hole on the side of the fixing block 18, releasing the fixing of the fixing block 18 and the U-shaped block 14 by the snap-fit ​​assembly. Finally, the storage mesh frame 16 is taken out from the carbonization chamber 1, completing one carbonization operation of the liquor lees. If the storage mesh frame 16 needs to be replaced or maintained, the above-mentioned snap-fit ​​assembly unlocking operation can be repeated for quick disassembly, which is convenient.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
