[0002] The preparation of activated carbon usually requires activation, carbonization, cooling, crushing, and ball milling to make carbon powder, and then the carbon powder is prepared into activated carbon through processes such as dehydration and drying. Currently, the dehydration process mainly uses a centrifuge to dehydrate the carbon powder. After the centrifuge removes the water from the carbon powder, a large amount of carbon powder usually adheres to the barrel wall of the centrifuge, and workers need to hold a scraper to scrape off the carbon powder on the barrel wall of the centrifuge, which is time-consuming and laborious in the operation process.

The housing is rotatably arranged on the frame, and the axis of rotation is perpendicular to the midpoint of the axis of the housing and is in a horizontal state.
[0007] The dewatering barrel is in a circular tube structure, with both ends open. One end is a material port, and the side wall of the dewatering barrel is provided with drainage meshes. A push plate is arranged inside the dewatering barrel and is arranged to move along the axis of the dewatering barrel. The outer wall of the push plate is in contact with the inner wall of the dewatering barrel. A stop block is arranged at the other end of the dewatering barrel to limit the push plate; the dewatering barrel is coaxially rotatably arranged inside the housing, and there is a gap between the outer wall of the dewatering barrel and the inner wall of the housing. The material port is located outside one end of the installation port, and the other end of the dewatering barrel is located inside the drainage port.
[0008] The driving motor is arranged outside the housing, and the driving motor is connected to the dewatering barrel by means of gear transmission or belt transmission.

Specific embodiments
[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following describes the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0017] As Figure 1 , Figure 2 and Figure 4 shown, a toner spin - drying device includes: a frame 1, an outer shell 2, a spin dryer 3, and a drive motor 5.
[0018] The outer shell 2 has a circular tube structure with both ends open. One end is a drain port 21, and the other end is a mounting port 22. The outer shell 2 is rotatably arranged on the frame 1, and the axis of rotation is perpendicular to the mid - point of the axis of the outer shell 2 and is in a horizontal state.
[0019] The spin dryer 3 has a circular tube structure with both ends open. One end is a material inlet 31. The side wall of the spin dryer 3 is provided with drainage meshes. A push plate 4 is arranged inside the spin dryer 3 and is movable along the axis of the spin dryer 3. The outer wall of the push plate 4 is in contact with the inner wall of the spin dryer 3. A stop block 32 is provided at the other end of the spin dryer 3 to limit the push plate 4 to prevent the push plate 4 from falling. The spin dryer 3 is coaxially and rotatably arranged inside the outer shell 2, and there is a gap between the outer wall of the spin dryer 3 and the inner wall of the outer shell 2. The material inlet 31 is located outside one end of the mounting port 22, and the other end of the spin dryer 3 is located inside the drain port 21. During assembly, the spin dryer 3 can be inserted into the outer shell 2 from one end of the mounting port 22.
[0020] The drive motor 5 is arranged outside the outer shell 2, and the drive motor 5 is connected to the spin dryer 3 by means of gear transmission or belt transmission.
[0021] Before loading, by rotating the outer shell 2 to make the drain port 21 face downward, at this time the material port 31 faces upward, and the cleaned toner is added into the drying barrel 3 through the material port 31. A push plate 4 is pushed towards the bottom of the drying barrel 3 by using a rod or a similar tool; then the driving motor 5 is started to drive the drying barrel 3 to rotate, so as to discharge the excess water of the toner by centrifugal force, and the liquid thrown out will automatically drain downward from the drain port 21.
[0022] After the drying work is completed, the driving motor 5 stops working, and the outer shell 2 is rotated to make the material port 31 face downward, and the toner can be discharged downward from the material port 31. By using a rod or a similar toolbox material port 31 to push the push plate 4, the toner attached to the inner wall of the drying barrel 3 can be scraped off at one time, which can effectively improve the discharging efficiency and the process is more relaxed and fast; and this kind of drying device is convenient to clean from both ends, which is more convenient to clean the inside of the drying device and convenient to discharge the liquid during cleaning.
[0023] Preferably, as Figure 1 、 Figure 2 shown, a pair of rotating shafts 23 are provided on the outer walls of the middle section of the outer shell 2 on opposite sides. The axis of the rotating shaft 23 intersects the axis of the outer shell 2. The frame 1 is provided with a pair of vertically arranged support frames 11, and the two rotating shafts 23 are respectively rotatably arranged on the support frames 11 on both sides.
[0024] Further preferably, as Figure 1 、 Figure 2 shown, the rotating shafts 23 each have a positioning hole 231, and its axis is parallel to the axis of the outer shell 2. A vertically arranged positioning pin 12 is passed through the top of the support frame 11. When the positioning pin 12 is connected to the positioning hole 231, the outer shell 2 is in a vertical state, so that the position state of the outer shell 2 can be locked during feeding, drying and discharging, and the outer shell 2 is prevented from shaking randomly.
[0025] Preferably, as Figures 2 to 4 shown, a detachable pressing ring 24 is provided at the end of the mounting port 22, which can specifically adopt screw connection. An annular groove is formed between the inner wall of the pressing ring 24 and the end face of the mounting port 22. A plurality of rollers 33 are arranged in a circumferential array on the outer wall of the drying barrel 3 corresponding to one end of the material port 31. The axis of the roller 33 is perpendicular to and intersects the axis of the drying barrel 3, and the roller 33 rolls in the annular groove to limit the relative position of the drying barrel 3 and the outer shell 2 in the axial direction, and at the same time ensure the smoothness of the rotation of the drying barrel 3.
[0026] Preferably, as Figure 2 、 Figure 4 shown, a plurality of cylindrical rollers 34 are arranged in a circumferential array on the outer wall of the drying barrel 3, and their axes are parallel to the axis of the drying barrel 3. The cylindrical rollers 34 are in rolling contact with the inner wall of the outer shell 2 to improve the stability of the rotation of the drying barrel 3.
[0027] As a further preferred solution, multiple circles of cylindrical rollers 34 are provided along the length direction of the drying barrel 3.
[0028] Preferably, as Figure 2 shown, a counterweight 41 is provided on the side of the push plate 4 facing the drain port 21 to increase the overall weight of the push plate 4; when discharging, the push plate 4 can automatically move downward, so as to scrape out the toner; when feeding, the push plate 4 can also automatically fall, reducing the manual operation link.
[0029] The above are only the preferred embodiments of the present invention and do not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
