[0027] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0028] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] Activated carbon is a general term for carbon materials that are prepared from carbon-containing raw materials such as wood, coal, and petroleum coke through pyrolysis and activation. It has a well-developed pore structure, a large specific surface area, and abundant surface chemical groups, and has a strong specific adsorption capacity.

[0030] In related technologies, existing rotary kilns have difficulty controlling the amount of raw materials fed at one time during filling, resulting in too much or too little material being fed at one time, which affects the quality of the raw material calcination process.

[0031] To address some of the problems in related technologies, this application provides a rotary kiln. When it is necessary to quantitatively add material to the inside of the rotary kiln body 11, simply start the motor 17 to move the toothed plate 16 and the movable block 14. This allows the activated carbon raw material inside the storage bin 18 to be added to the storage trough 141. Then, start the motor 17 again to reset the movable block 14 and add the activated carbon raw material to the inside of the rotary kiln body 11. In this way, activated carbon can be quantitatively added to the inside of the rotary kiln body 11 each time. Repeating the above operation can quantitatively fill the rotary kiln body 11. This device is simple to operate, facilitates quantitative feeding of the rotary kiln body 11, and improves the quality of raw material calcination processing.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-4 This application provides a rotary kiln, including a feeding assembly 1. The feeding assembly 1 includes: a rotary kiln body 11 with a fixed base 12 on its outer side and connected thereto; a box body 13 disposed on the top of the fixed base 12; a feed inlet 131 opened on the top of the box body 13; a discharge outlet 132 opened on the bottom of the box body 13 and connected to the rotary kiln body 11; a movable block 14 disposed on the inner side of the box body 13; a storage trough 141 opened on the top of the movable block 14; a through groove 15 opened on the box body 13; a toothed plate 16 disposed on the movable block 14 and passing through the through groove 15; a motor 17 disposed on the box body 13; a gear 171 disposed on the output shaft of the motor 17 and meshing with the toothed plate 16; and a storage hopper 18 disposed on the box body 13 and connected to the feed inlet 131.

[0034] When it is necessary to quantitatively fill the rotary kiln body 11, the motor 17 is started by an external power source, which drives the gear 171 to rotate. The rotating gear 171 drives the toothed plate 16 that meshes with it to move, so that the feed port 131 opened at the top of the box 13 connects with the storage tank 141. In this way, the activated carbon inside the storage tank 18 will enter the inner side of the storage tank 141. After the filling is completed, the motor 17 is reversed, which can reset the movable block 14. In this way, the storage tank 141 will connect with the discharge port 132, and the discharge port 132 is connected to the fixed base 12. The toothed plate 16 can limit the bottom of the storage tank 18 to prevent the activated carbon inside the storage tank 18 from overflowing. The activated carbon leaks out. Since the space inside the storage tank 141 is fixed, the activated carbon can be added quantitatively to the rotary kiln body 11 each time. Then, the above operation can be repeated to quantitatively fill the rotary kiln body 11. The device is simple to operate and facilitates quantitative feeding of the rotary kiln body 11, which increases the quality of raw material calcination. The rotary kiln body 11 is a structure that desorbs impurities in the activated carbon and restores its original activity. Referring to paragraphs "

[0026] " and "

[0029] " in the specification of patent "CN219977055U", the device is common knowledge and will not be described in detail here.

[0035] In some embodiments, an auxiliary component 2 is provided on the movable block 14, the auxiliary component 2 including: pulleys 21 symmetrically arranged on the movable block 14; and grooves 22 symmetrically formed on the housing 13.

[0036] Pulleys 21 are symmetrically arranged on both sides of the movable block 14, and sliding grooves 22 are symmetrically opened on the inner side of the housing 13. When the movable block 14 moves left and right, the pulleys 21 can move inside the sliding grooves 22, which makes the movable block 14 move more conveniently and smoothly, and increases the structural stability of the device.

[0037] In some embodiments, the auxiliary component 2 further includes a baffle 23 disposed on the toothed plate 16.

[0038] A baffle 23 is provided at one end of the toothed plate 16, which can limit the toothed plate 16 and limit the range of motion of the movable block 14. This prevents the tail of the movable block 14 from hitting the inside of the housing 13 every time it moves, thus avoiding damage to other parts and increasing the service life of the device.

[0039] In some embodiments, the auxiliary component 2 further includes a vibration motor 24 disposed on the movable block 14.

[0040] A vibration motor 24 is installed on one side of the movable block 14. When in use, the vibration motor 24 is activated to make the movable block 14 vibrate, which can effectively prevent activated carbon from clogging the inside of the storage tank 141, making it more convenient to use.

[0041] In some embodiments, the housing 13 and the mounting base 12 are connected by bolts.

[0042] The housing 13 and the mounting base 12 are connected by bolts. This makes it easy to disassemble the housing 13 to replace or repair the parts if they are damaged or deformed in the future, so as not to affect the subsequent use and increase the practical effect.

[0043] In some embodiments, the auxiliary component 2 further includes a mating groove 25 formed on the top of the fixing base 12.

[0044] A mating groove 25 is provided on the top of the fixing base 12. When installing the box 13, the box 13 is inserted into the inside of the mating groove 25, which can limit the position of the box 13 and facilitate the subsequent use of bolts to fix the box 13, thus increasing work efficiency.

[0045] In some embodiments, the auxiliary component 2 further includes a collection box 26 disposed on the fixing base 12.

[0046] A collection box 26 is installed on one side of the fixed base 12 to collect the debris that falls from the toothed plate 16. This prevents activated carbon debris from falling to the ground without a collection mechanism, which would require subsequent cleaning by the operator. This reduces the operator's workload and increases work efficiency.

[0047] In some embodiments, the auxiliary component 2 further includes a rubber pad 27 disposed inside the through groove 15.

[0048] A rubber pad 27 is provided on the inner side of the through groove 15. This can clean the surface of the toothed plate 16 when it moves back and forth, prevent excessive debris from adhering to the surface of the toothed plate 16, thus affecting the movement of the toothed plate 16 and increasing the service life of the toothed plate 16.
