[0002] A carbonization furnace is a processing device for carbonizing materials into products such as activated carbon. During the same carbonization process, the carbonization time in the furnace is equal. If there is a large difference in particle size among the materials to be carbonized, it will lead to different carbonization degrees of large-grained raw materials and small-grained raw materials. Sometimes, the small-grained raw materials have been over-carbonized while the large-grained raw materials have not been completely carbonized. Therefore, before carbonization treatment, the raw materials need to be classified according to preset size specifications first, and then the carbonization parameters of the carbonization furnace are set according to the classification, and the materials are carbonized in batches according to the classification. If it is possible to screen the raw materials in the carbonization furnace and the screened materials are classified and placed in different carbonization chambers for classification carbonization, it will change the inconvenience of the existing out-of-furnace screening. Therefore, how to optimize the device for screening raw materials in the carbonization furnace will improve the carbonization technology of the carbonization furnace. Summary of the Utility Model

[0018] The technical solutions in the embodiments of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the application. Additionally, the phrase "in one embodiment" or "in an embodiment" that appears throughout the specification does not necessarily refer to the same embodiment. Moreover, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0019] It should also be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity from another entity, and do not necessarily require or imply any actual relationship or order between these entities. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that an article or terminal device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such an article or terminal device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the article or terminal device comprising the element.

[0020] A carbonization furnace is a processing device for carbonizing materials into products such as activated carbon. During the same carbonization process, the carbonization time in the furnace is equal. If there is a large difference in the particle sizes of the materials to be carbonized, it will lead to different degrees of carbonization of large-grained and small-grained raw materials. Sometimes, the small-grained raw materials have been over-carbonized while the large-grained raw materials have not been completely carbonized. Therefore, before carbonization treatment, the raw materials need to be classified according to preset size specifications first, and then the carbonization parameters of the carbonization furnace are set according to the classification, and the materials are carbonized in batches according to the classification. If it is possible to screen the raw materials in the carbonization furnace and the screened materials are classified and placed in different carbonization chambers for classification carbonization, it will change the inconvenience of the existing out-of-furnace screening. Therefore, the present utility model improves the carbonization technology of the carbonization furnace by optimizing the structure of the device for screening raw materials in the carbonization furnace.

[0021] The present utility model provides a grading and feeding device for a carbonization furnace, which includes a plurality of fan-shaped feeding layers 1 and a screening mechanism 2. The plurality of fan-shaped feeding layers 1 are of a fan-shaped tray structure, and the bottom of the fan-shaped tray includes a discharge port. The plurality of fan-shaped feeding layers 1 are arranged side by side in a circular shape. The screening mechanism 2 is arranged above the fan-shaped feeding layers 1, and the discharge pipe 21 in the screening mechanism 2 corresponds to the fan-shaped feeding layers 1 one by one;

[0022] The screening mechanism 2 includes a plurality of screening layers 3 and a vibration assembly 4. The vibration assembly 4 is connected to the bottom of the bottom screening layer 3. The vibration assembly 4 includes a driving device, a bellows gasket 41, and a base 42. Both ends of the bellows gasket 41 are respectively connected to the base 42 and the bottom screening layer 3. The base 42 is connected to the inner furnace wall of the carbonization furnace. The driving device is arranged within the middle hollow range of the bellows gasket 41. The screening layer 3 further includes a screening frame 31 and a screening mesh 32. The screening mesh 32 is detachably connected to the inner side wall of the screening frame 31, and the middle of the screening mesh 32 protrudes. The bottom edge of the screening frame 31 includes a flanging that turns outwards, and a connecting lock is provided on the flanging. The connecting lock is connected to the edge of the screening frame 31 of the bottom screening layer 3. The driving device drives the screening mesh 32 to rotate and vibrate simultaneously at a preset rotational speed and a preset amplitude.

[0023] As Figure 1 and Figure 2 As shown, the grading and feeding device of the carbonization furnace provided by the present utility model includes a fan-shaped feeding layer 1 and a screening mechanism 2. After the screening mechanism 2 screens the materials, they flow into different fan-shaped feeding layers 1 respectively. The feeding layer with a fan-shaped tray structure is arranged in a circular manner, which is not only convenient for material dropping but also convenient for discharging materials in the circumferential direction. Among them, the screening mechanism 2 includes a plurality of screening layers 3 and a vibration assembly 4. The vibration assembly 4 drives the plurality of screening layers 3 to vibrate, leaving materials with different particles on different screening layers 3. When the screening mesh 32 of the screening layer 3 rotates to the discharging position, the materials on this layer are sent out and finally enter different carbonization chambers, ultimately achieving the purpose of the carbonization furnace itself screening materials. The grading and feeding device in the present utility model has a simple structure and good material distribution effect, realizes the purpose of automatic material distribution in the carbonization furnace, optimizes the structure of the material distribution device of the carbonization furnace, and improves the practicability of the existing carbonization furnace.

[0024] In some embodiments, the aforementioned screening layer 3 further includes a discharge baffle 33. The discharge baffle 33 is elastically connected to the inner wall of the screening frame 31, and the discharge baffle is arranged at the pipe orifice of the discharge pipe 21.

[0025] As Figure 3 As shown, the back of the baffle is connected to the inner wall of the screening frame 31 through a spring, so as to facilitate adjusting the discharge speed and discharge amount by adjusting the spring. If the screening mesh 32 vibrates in the vertical direction and rotates in the counterclockwise direction, after vibration, the materials remaining on this layer of the screening mesh 32, as the screening mesh 32 rotates, the materials on the screening mesh 32 rotate counterclockwise to reach the pipe orifice of the discharge pipe 21, and under the gathering effect of the baffle, the materials are pushed into the discharge pipe 21.

[0026] Wherein, the bottom edge of the aforementioned discharge baffle 33 is connected to the surface of the screen 32 with a preset gap. This preset gap is related to the particle size of the material filtered in this layer. As long as it is ensured that the baffle can block the filtered material near the discharge pipe 21 and prevent the material from getting stuck between the screen 32 and the bottom edge of the discharge baffle 33, this embodiment does not make specific limitations on this.

[0027] It should be noted that the number of mesh holes of the screen in the multiple layers of the screen material layer 3 increases sequentially from top to bottom. That is, in the vertical direction, the number of mesh holes of the topmost screen 32 is less than that of the bottommost screen 32, that is, the particle size filtered by the topmost screen 32 is larger than that of the particles at the bottommost layer. In addition, the driving device in the vibration assembly 4 includes a drive for controlling the rotation of the screen 32 and also includes a drive for controlling the up-and-down vibration of the screen 32.

[0028] In some embodiments, the inner side wall of the aforementioned screen frame 31 includes a convex block, and the convex block is fixed after overlapping with the screen 32. The design of this convex block facilitates the connection and fixation of the screen 32. The edge of the screen 32 can be connected to the convex block through a detachable buckle, and this embodiment will not elaborate in detail again.

[0029] In some embodiments, the aforementioned connection lock can be a bolt or a buckle. The function of this connection lock is to connect and fix the multiple layers of the screen material layer 3 into a whole, which is convenient for overall control and can also achieve the same-frequency vibration of multiple screens 32.

[0030] Of course, in other embodiments, a separate vibration drive can also be provided on each screen material layer 3, so that each screen material layer 3 vibrates at a different vibration frequency, because materials with different particle sizes have different tolerances to vibration, preventing damage to materials within a certain particle range under the same frequency.

[0031] Finally, the utility model provides a grading and feeding device for a carbonization furnace, which comprises a plurality of fan-shaped feeding layers 1 and a material screening mechanism 2. The plurality of fan-shaped feeding layers 1 are of a fan-shaped tray structure. The material screening mechanism 2 is arranged above the fan-shaped feeding layers 1, and the discharge pipes 21 in the material screening mechanism 2 correspond to the fan-shaped feeding layers 1 one by one. The material screening mechanism 2 comprises a plurality of screening layers 3 and a vibration assembly 4. The vibration assembly 4 is connected to the bottom of the bottom screening layer 3. The vibration assembly 4 comprises a driving device, an accordion pad 41 and a base 42. The two ends of the accordion pad 41 are respectively connected to the base 42 and the bottom screening layer 3. The base 42 is connected to the inner furnace wall of the carbonization furnace. The driving device is arranged within the middle hollow range of the accordion pad 41. The screening layer 3 further comprises a screening frame 31 and a screening mesh 32. The screening mesh 32 is detachably connected to the inner side wall of the screening frame 31, and the middle of the screening mesh 32 protrudes. The bottom edge of the screening frame 31 comprises a flanging turned outwards. The driving device drives the screening mesh 32 to rotate and vibrate simultaneously at a preset rotation speed and a preset amplitude. The utility model realizes the purpose of automatic material distribution in the carbonization furnace, optimizes the structure of the carbonization furnace and improves the practicability of the existing carbonization furnace.
