The feeding box 11 is placed on the top of the belt conveyor. The top of the feeding box 11 is provided with the box cover 12. The top of the box cover 12 is provided with the feeding hopper 13. The inside of the feeding box 11 is provided with the screen 14. One side of the feeding box 11 is provided with the discharge port 15.

[0036] In this embodiment, the feeding device 1 is mainly composed of a feeding box 11, a box cover 12, a feeding hopper 13, a screen 14 and a discharge port 15. The feeding box 11 is designed in the shape of a cuboid and is placed on the top of the belt conveyor for temporarily storing the activated carbon to be dried. The bottom of the feeding box 11 is kept a certain gap from the surface of the conveying belt of the belt conveyor to ensure that the activated carbon can fall onto the belt conveyor and be conveyed outward through the discharge port 15. The box cover 12 is installed on the top of the feeding box 11 to prevent dust, debris and the like from entering the inside of the feeding box 11 and keep the inside clean. The box cover 12 can be designed to be detachable for easy maintenance and cleaning. The feeding hopper 13 is provided on the top center of the box cover 12 and is funnel-shaped to facilitate pouring the activated carbon from above into the feeding box 11. The caliber of the feeding hopper 13 can be adjusted according to actual needs to adapt to activated carbon of different specifications. The screen 14 is installed inside the feeding box 11 below the feeding hopper 13. The mesh size of the screen 14 can be selected according to the particle size requirements of the activated carbon to remove large impurities and unqualified particles in the activated carbon. The screen 14 should be designed to be easy to disassemble and clean to keep it unobstructed. The discharge port 15 is provided on the bottom of one side of the feeding box 11. The size and shape of the discharge port 15 should ensure that the activated carbon can be smoothly output from the feeding box 11 while avoiding blockage and leakage.

[0037] In this embodiment, the user pours the activated carbon from the feeding hopper 13 into the feeding box 11. Due to the funnel-shaped design of the feeding hopper 13, the activated carbon can smoothly slide down the funnel slope onto the screen 14. The screen 14 can remove large impurities and unqualified particles in the activated carbon to ensure that the activated carbon entering the drying equipment 5 is uniform in particle size and reliable in quality. During the screening process, the operator can check the blockage of the screen 14 regularly and clean it in time. The screened activated carbon falls onto the conveying belt of the belt conveyor and is conveyed to the subsequent drying equipment 5 for drying treatment along with the movement of the belt conveyor through the discharge port 15.

[0038] In this embodiment, the design of the screen 14 can remove large impurities and unqualified particles in the activated carbon to ensure that the activated carbon entering the drying equipment 5 is uniform in particle size and reliable in quality. At the same time, the cooperative design of the feeding device 1 and the belt conveyor enables the activated carbon to smoothly fall from the feeding box 11 onto the belt conveyor, providing a strong guarantee for the subsequent drying treatment.

[0039] Please refer to Figure 4Further, in some embodiments, the discharging device 3 comprises a discharging box 31, a feeding port 32, a guide plate 33 and a discharge pipeline 34. The feeding port 32 is arranged on one side of the discharging box 31 and is connected with the belt conveyor. The guide plate 33 is arranged inside the discharging box 31. The discharge pipeline 34 is arranged at the bottom end of the other side of the discharging box 31 and is connected with the inside of the discharging box 31.

[0040] In the present embodiment, the discharging device 3 mainly comprises a discharging box 31, a feeding port 32, a guide plate 33 and a discharge pipeline 34. The discharging box 31 is designed in the shape of a cuboid, and the internal space thereof is used for temporarily storing the activated carbon discharged from the belt conveyor. The material of the discharging box 31 should be selected from wear-resistant and corrosion-resistant materials to withstand the impact and friction of the activated carbon. The feeding port 32 is arranged on one side of the discharging box 31 and is connected with the end of the belt conveyor. The width and height of the feeding port 32 should be designed according to the width of the belt conveyor and the flow of the activated carbon to ensure that the activated carbon can smoothly enter the discharging box 31 from the conveying belt. The guide plate 33 is arranged inside the discharging box 31 and is located below the feeding port 32. The design of the guide plate 33 should make the activated carbon slide in a certain direction when falling into the discharging box 31 to avoid the accumulation and blockage of the activated carbon in the discharging box 31. The angle and shape of the guide plate 33 can be adjusted and optimized according to the actual situation. The discharge pipeline 34 is arranged at the bottom end of the other side of the discharging box 31 and is connected with the inside of the discharging box 31. The discharge pipeline 34 is inclined downward to facilitate the smooth discharge of the activated carbon from the discharging box 31. The diameter and inclination angle of the discharge pipeline 34 should be designed according to the flow and discharge speed of the activated carbon to ensure that the activated carbon can flow out smoothly without causing blockage.

[0041] In the present embodiment, when the belt conveyor conveys the dried activated carbon to the end, the activated carbon enters the discharging box 31 through the feeding port 32. Due to the design of the guide plate 33, the activated carbon slides in a certain direction when falling into the discharging box 31 to avoid accumulation and blockage. In the discharging box 31, the activated carbon slides along the guide plate 33 to the bottom of the box. As the activated carbon continuously accumulates, they gradually fill the lower space of the discharging box 31. When the activated carbon accumulates to a certain amount, they begin to flow out in the downward inclined direction of the discharge pipeline 34. The inclination angle and diameter of the discharge pipeline 34 are designed reasonably to control the flow-out speed of the activated carbon. By adjusting the inclination angle or diameter of the discharge pipeline 34, the flow of the activated carbon can be accurately controlled to meet the needs of the subsequent processing process.

[0042] In this embodiment, through the design of the guide plate 33, the sliding direction of the activated carbon in the discharge box 31 can be guided to avoid accumulation and blockage. At the same time, the design of the discharge pipeline 34 is reasonable, which can control the outflow speed of the activated carbon to meet the needs of the subsequent processing process. In addition, the cooperation design of the discharge device 3 and the belt conveyor makes the activated carbon smoothly enter the discharge box 31 from the conveyor belt and be smoothly discharged through the discharge pipeline 34, which provides a strong guarantee for the subsequent collection and processing.

[0043] Further, in some embodiments, the stirring device 55 includes a driving motor 551, an output shaft 552, and stirring rods 553. The driving motor 551 is placed outside the drying box 51 and is in transmission connection with the output shaft 552 through a coupling. The output shaft 552 penetrates the drying box 51 and reaches the inside of the drying box 51. The outer surface of the output shaft 552 is connected with multiple groups of stirring rods 553.

[0044] In this embodiment, the stirring device 55 mainly consists of a driving motor 551, an output shaft 552, a coupling, and stirring rods 553. The driving motor 551 is selected as a high-performance motor and is placed outside the drying box 51 to provide power for the stirring device 55. The selection of the motor should consider the size of the drying box 51, the amount of activated carbon, and the drying efficiency, etc. to ensure that the motor can provide sufficient torque and speed. The output shaft 552 is designed as a long shaft and penetrates the drying box 51. The output shaft 552 is in transmission connection with the driving motor 551 through a coupling. The material of the output shaft 552 should be selected as a high-temperature-resistant and corrosion-resistant material to withstand the high-temperature environment and friction of the activated carbon during the drying process. The coupling is a key component connecting the driving motor 551 and the output shaft 552, which has the functions of transmitting torque and buffering and damping. The selection of the coupling should consider the torque and speed of the motor and the working conditions of the drying box 51 to ensure that the coupling can stably and reliably transmit power. The stirring rods 553 are connected to the outer surface of the output shaft 552 and are designed as multiple groups, each group containing several stirring rods 553. The shape and number of the stirring rods 553 should be designed according to the size of the drying box 51 and the characteristics of the activated carbon to ensure that the stirring effect is uniform and sufficient. The material of the stirring rods 553 should also be selected as a high-temperature-resistant and corrosion-resistant material.

[0045] In this embodiment, when the driving motor 551 starts, power is transmitted to the output shaft 552 through the coupling. The output shaft 552 starts to rotate under the drive of the motor, driving the stirring rods 553 to rotate together. The stirring rods 553 continuously stir the activated carbon inside the drying box 51 with the rotation of the output shaft 552. The design of the stirring rods 553 enables the activated carbon to be fully mixed and dispersed during the drying process, thereby improving the drying efficiency and ensuring the quality of the activated carbon.

[0046] In the embodiment, the cooperation of the driving motor 551, the output rotating shaft 552 and the stirring rod 553 can realize sufficient stirring and mixing of the activated carbon, improve the drying efficiency and drying quality, and meanwhile, the design of the stirring device 55 also considers the high-temperature environment and the characteristics of the activated carbon, and selects the high-temperature-resistant and corrosion-resistant material to ensure the stability and reliability of the stirring device 55.

[0047] Please refer to Figure 5 Further, in some embodiments, the stirring rod 553 is divided into an upper end and a lower end, the upper end of the stirring rod 553 is connected with the outer surface of the output rotating shaft 552, and the lower end of the stirring rod 553 is in the form of a horizontal plate and can contact the top of the belt conveyor.

[0048] In the embodiment, the stirring rod 553 is divided into an upper end and a lower end, the upper end of the stirring rod 553 is connected with the outer surface of the output rotating shaft 552, and the lower end of the stirring rod 553 is in the form of a horizontal plate and can contact the top of the belt conveyor.

[0049] In the embodiment, when the output rotating shaft 552 rotates under the driving of the driving motor 551, the stirring rod 553 also rotates. The lower end (horizontal plate) of the stirring rod 553 continuously contacts the activated carbon on the belt conveyor during the rotation process, lifts the activated carbon, promotes the uniform drying of the activated carbon, prevents the accumulation and blockage of the activated carbon, and makes the activated carbon more fully contact the microwave radiation during the drying process, thereby improving the drying efficiency, promoting the evaporation and discharge of the internal moisture of the activated carbon, and further improving the drying quality.

[0050] Further, in some embodiments, the rotating direction of the output rotating shaft 552 is consistent with the conveying direction of the belt conveyor.

[0051] In this embodiment, the rotation of the output shaft 552 is consistent with the direction of the belt conveyor, which means that when the belt conveyor transports the activated carbon from one end to the other, the output shaft 552 is synchronized, which helps to ensure the continuity and stability of the activated carbon during transportation and agitation. The agitation rods 553 are evenly distributed along the axis of the output shaft 552, ensuring that the agitation rods 553 can uniformly and continuously agitate the activated carbon during transportation. Further preferably, in order to ensure the synchronization of the output shaft 552 and the belt conveyor, the speed of the driving motor 551 should match the transportation speed of the belt conveyor.

[0052] In this embodiment, when the belt conveyor starts to run, the activated carbon is continuously transported into the drying device, at the same time, the output shaft 552 starts to rotate under the drive of the driving motor 551, and the agitation rods 553 rotate accordingly. The direction of rotation of the output shaft 552 is consistent with the direction of the belt conveyor, and the agitation rods 553 can continuously and uniformly agitate the activated carbon during rotation, preventing it from piling up and clogging.

[0053] In this embodiment, the agitation of the agitation rods 553 not only helps to evenly distribute the activated carbon, but also promotes its full contact with the hot air inside the drying device, which increases the heating area of the activated carbon and improves the drying efficiency.

[0054] Further, in some embodiments, the distribution device 4 includes a distribution box 41, a through port 42, and a distribution plate 43. The distribution box 41 is arranged above the belt conveyor, and the left and right sides of the distribution box are provided with through ports 42. The bottom of the through port 42 is provided with a distribution plate 43.

[0055] In this embodiment, the distribution box 41 is arranged above the belt conveyor to receive and distribute the activated carbon to be dried, and controls the height of the activated carbon. The left and right sides of the distribution box 41 are provided with through ports 42, which allow the activated carbon to flow out of the distribution box 41. The shape and size of the distribution box 41 should be designed according to the actual production requirements to ensure that it can accommodate enough activated carbon and distribute it smoothly onto the belt conveyor. The bottom of the through port 42 is provided with a distribution plate 43, which is mainly used to evenly distribute the activated carbon on the belt conveyor. The design of the distribution plate 43 should take into account the flowability and uniformity of the activated carbon to ensure that the activated carbon forms a uniform thin layer on the belt conveyor. Further preferably, the distribution plate 43 can be designed to be adjustable to adjust the distribution density and thickness of the activated carbon according to different production requirements.

[0056] In the present embodiment, when the activated carbon is fed into the distribution box 41, the distribution plate 43 evenly distributes the activated carbon on the belt conveyor, forming a uniform thin layer, and the belt conveyor continuously runs under the drive of the motor to transport the activated carbon distributed thereon into the drying device for drying.

[0057] In the present embodiment, the uniform distribution and transportation of the activated carbon are achieved through the cooperation of the distribution box 41, the through hole 42 and the distribution plate 43, which provides a strong guarantee for the subsequent drying process.

[0058] Further, in some embodiments, the inlet end 56 of each group of drying devices 5 is in communication with the outlet end 57.

[0059] In the present embodiment, the plurality of groups of drying devices 5 are arranged in a horizontal connection arrangement, and the outlet end 57 of each group of drying devices 5 is in communication with another group, so that the activated carbon enters each group of drying devices 5 for drying under the transportation of the belt conveyor.

[0060] Further, in some embodiments, the activated carbon production drying device further comprises a protective cover 7, which is placed above the belt conveyor, and further preferably, the protective cover 7 is arranged between the drying device and the unloading device 3.

[0061] In the present embodiment, the protective cover 7 is placed above the belt conveyor, and its main purpose is to protect the belt conveyor and the activated carbon thereon from external environmental interference. The shape and size of the protective cover 7 should be designed according to the actual size and layout of the belt conveyor to ensure that it can completely cover the belt conveyor and leave necessary operation and maintenance space. The material of the protective cover 7 should be selected from corrosion-resistant, high-temperature-resistant and easy-to-clean materials such as stainless steel or special alloy to ensure its long-term stable operation. The protective cover 7 is used to prevent external pollutants (such as dust, moisture, etc.) from entering the drying device, affecting the drying effect and quality of the activated carbon.

[0062] In the present embodiment, the working principle of the protective cover 7 is mainly based on its physical isolation effect. When the activated carbon is transported to the unloading device 3 on the belt conveyor after drying, the protective cover 7 isolates the belt conveyor and the activated carbon thereon from the external environment, which can effectively prevent external pollutants from entering the drying device and maintain the cleanliness and stability of the drying environment. At the same time, the protective cover 7 can also isolate the influence of external temperature fluctuations on the drying process, ensuring the stability of the internal temperature of the drying device

[0063] In the present embodiment, the activated carbon production drying device realizes effective protection of the belt conveyor and the activated carbon thereon by adding the design of the protective cover 7, which not only improves the drying effect and quality, but also ensures the production safety and long-term stable operation of the equipment.
