Description

Technical Field

[0001] The utility model relates to a finished product drying device for activated carbon production, belonging to the technical field of drying devices. Background Art

[0002] Activated carbon drying equipment is a special equipment used to remove the residual moisture in the production process of activated carbon to meet specific moisture content requirements. These devices usually include horizontal rotating drying furnaces, fluidized bed dryers, spray dryers, etc. The selection of drying equipment is usually based on the physical form of activated carbon, production scale and specific application requirements.

[0003] To ensure that activated carbon does not deteriorate during storage and transportation and improve its adsorption capacity. During the drying process, the structure of activated carbon is kept stable to prevent damage caused by high temperature or other factors. Moisture is effectively removed through heat conduction, convection and radiation, while minimizing energy consumption.

[0004] In special application scenarios with special requirements for activated carbon, such as application scenarios with high requirements for adsorption performance, such as gas purification, precious metal recovery, etc., the microporous structure of activated carbon must be retained to ensure high adsorption capacity. However, high temperature or too fast rotation will damage the microporous structure and reduce the adsorption performance. Therefore, low-speed drying is required to reduce structural damage.

[0005] Another example: For activated carbon used in the food or pharmaceutical fields, a low ash content must be maintained to ensure safe use in the food or pharmaceutical fields. High-speed drying may increase the ash content. Therefore, low-speed drying is required to reduce the risk of ash contamination.

[0006] Since low-speed drying is mainly for protecting the physical properties of activated carbon and its moisture evaporation rate is slow, a longer drying time is required. Content of the Utility Model

[0007] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a finished product drying device for activated carbon production to solve the problems of the existing technology.

[0008] To achieve the above purpose, the utility model is realized through the following technical solutions:

[0009] A finished product drying device for activated carbon production, comprising: a drying cylinder for placing activated carbon particles to be dried;

[0010] A material turning mechanism rotatably arranged inside the drying cylinder and a driving component for driving the material turning mechanism to rotate;

[0011] A heat source component arranged inside the drying cylinder, and the heat source component heats the activated carbon particles to be dried;

[0012] A material lifting component arranged below the drying cylinder, the material lifting component being directly below the turning mechanism, the material lifting component comprising:

[0013] A plurality of air outlet holes arranged at the inner bottom of the drying cylinder, a blower arranged below the drying cylinder, and an output port of the blower communicating with the inside of the drying cylinder through the air outlet holes;

[0014] It further includes a control module, and the control module is electrically connected to the heat source component, the driving component, and the blower;

[0015] Through the cooperation of the control module and the turning mechanism, the activated carbon particles are stirred, and through the cooperation of the air outlet holes and the blower, an air flow is output, and the air flow lifts the activated carbon particles located at the inner bottom of the drying cylinder.

[0016] As a further improvement, the drying cylinder includes a lower cylinder base and an upper cylinder cover covering the upper part of the lower cylinder base. There is a accommodating space between the upper cylinder cover and the lower cylinder base. An input port is arranged above the upper cylinder cover, and an output port is arranged on the side of the lower cylinder base. The activated carbon particles to be dried are added into the accommodating space through the input port, and after drying is completed, they are discharged through the output port on the side.

[0017] As a further improvement, it further includes an exhaust pipe arranged above the upper cylinder cover, and the air flow output by the material lifting component carries moisture and is discharged from the exhaust pipe.

[0018] As a further improvement, the turning mechanism includes a rotating shaft horizontally arranged inside the drying cylinder, at least three turntables arranged on the rotating shaft, a plurality of rods connecting the turntables, and a plurality of groups of paddles arranged at intervals on the outer side of the rods. The ends of the paddles are close to the inner side of the drying cylinder, and the output end of the driving component is connected to the rotating shaft;

[0019] Through the cooperation of the driving component, the rotating shaft, and the turntables, the paddles on the rods are driven to stir the activated carbon particles in the drying cylinder.

[0020] As a further improvement, the paddles close to the input port are inclined from the input port towards the output port, and the paddles close to the output port are horizontally arranged.

[0021] As a further improvement, the lower cylinder base includes a first bottom plate for receiving the activated carbon particles, and the air outlet holes are arranged on the first bottom plate.

[0022] As a further improvement, a second bottom plate is arranged below the first bottom plate, and a sealed air cavity is formed between the first bottom plate and the second bottom plate;

[0023] The air outlet of the blower is inserted into the second bottom plate and communicates with the air cavity.

[0024] As a further improvement, the material lifting assembly further includes a flexible sleeve embedded and installed in the corresponding side groove inside the air outlet hole. A through hole is provided in the middle of the flexible sleeve. When the air flow is output, the through hole is opened, and when the air flow stops outputting, the through hole is closed.

[0025] As a further improvement, the flexible sleeve includes a positioning part inserted into the first bottom plate and a diversion part of a partial air outlet hole. The width of the diversion part gradually decreases from bottom to top. Through the cooperation of the positioning part and the diversion part, the activated carbon particles are blocked from clogging the air outlet holes.

[0026] The beneficial effects of the present utility model are as follows:

[0027] In the present utility model, the material turning mechanism is installed inside the drying cylinder and rotated by the driving assembly. The material turning mechanism slowly stirs the activated carbon particles. Since the microporous structure of activated carbon is crucial for high adsorption performance, the low-speed rotation of the material turning mechanism can ensure the integrity of the microporous structure of the activated carbon particles.

[0028] The heat source assembly is located inside the drying cylinder and directly heats the activated carbon particles to be dried. The design of the internal heat source avoids the problem of heat loss in the traditional external heating method and can transfer heat to the activated carbon more efficiently. At the same time, since the heat source assembly is located inside, the heat distribution is more uniform, thereby reducing the phenomenon of uneven temperature control.

[0029] The material lifting assembly sends air flow into the drying cylinder through the air outlet hole, causing the activated carbon particles at the bottom to be lifted by the air flow. Through the action of the air flow, the uniform heating of the particles can be further promoted, and the evaporation of moisture can be accelerated. In addition, the combined use of the material lifting assembly and the material turning mechanism can effectively prevent uneven drying caused by particle accumulation. Through the design of low-speed stirring and internal heat source, the microporous structure of the activated carbon is effectively protected during the drying process, ensuring its effect in high adsorption performance application scenarios.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0041] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more unless otherwise specifically defined.

[0042] Special requirements for activated carbon in special application scenarios, such as application scenarios with high requirements for adsorption performance, such as gas purification, precious metal recovery, etc., must retain the microporous structure of activated carbon to ensure high adsorption capacity. However, high temperature or too fast rotation will damage the microporous structure and reduce the adsorption performance. Therefore, low-speed drying is required to reduce structural damage. Since low-speed drying is mainly to protect the physical properties of activated carbon and its water evaporation rate is slow, a longer drying time is required.

[0043] Refer to Figure 1-8 As shown, a finished product drying device for activated carbon production includes;

[0044] A drying cylinder 1 for placing activated carbon particles to be dried;

[0045] A material turning mechanism rotatably arranged inside the drying cylinder 1 and a driving assembly 5 for driving the material turning mechanism to rotate;

[0046] A heat source assembly arranged inside the drying cylinder 1, and the heat source assembly heats the activated carbon particles to be dried;

[0047] A material lifting assembly arranged below the drying cylinder 1, the material lifting assembly is directly below the material turning mechanism, and the material lifting assembly includes:

[0048] A plurality of air outlet holes 31 are arranged at the inner bottom of the drying cylinder 1, and a blower 32 is arranged below the drying cylinder 1. The output port 15 of the blower 32 communicates with the inside of the drying cylinder 1 through the air outlet holes 31;

[0049] It further includes a control module 7, and the control module 7 is electrically connected to the heat source assembly, the driving assembly 5, and the blower 32;

[0050] Through the cooperation of the control module 7 and the material turning mechanism, the activated carbon particles are stirred, and through the cooperation of the air outlet holes 31 and the blower 32, an air flow is output, and the air flow raises the activated carbon particles located at the inner bottom of the drying cylinder 1.

[0051] By installing the material turning mechanism inside the drying cylinder 1 and rotating it through the driving assembly 5. The material turning mechanism slowly stirs the activated carbon particles. Since the microporous structure of activated carbon is crucial for high adsorption performance, the low-speed rotation of the material turning mechanism can ensure the integrity of the microporous structure of the activated carbon particles.

[0052] The heat source assembly is located inside the drying cylinder 1 and directly heats the activated carbon particles to be dried. The design of the internal heat source avoids the problem of heat loss in the traditional external heating method and can transfer heat to the activated carbon more efficiently. At the same time, since the heat source assembly is located inside, the heat distribution is more uniform, thus reducing the phenomenon of uneven temperature control.

[0053] The material lifting assembly sends the air flow into the inside of the drying cylinder 1 through the air outlet holes 31, so that the activated carbon particles located at the bottom are lifted by the air flow. Through the action of the air flow, the uniform heating of the particles can be further promoted, and the evaporation of moisture can be accelerated. In addition, the combined use of the material lifting assembly and the material turning mechanism can effectively prevent uneven drying caused by particle accumulation. Through the design of low-speed stirring and internal heat source, the microporous structure of the activated carbon is effectively protected during the drying process, ensuring its effect in high adsorption performance application scenarios.

[0054] Through the cooperation of the material turning mechanism and the material lifting assembly, the activated carbon particles in the drying cylinder 1 can be evenly heated, avoiding the difference in drying effect caused by uneven temperature distribution in traditional equipment.

[0055] Wherein, the drying cylinder 1 includes a lower cylinder base 12 and an upper cylinder cover 11 covering the upper part of the lower cylinder base 12. There is an accommodation space 13 between the upper cylinder cover 11 and the lower cylinder base 12. An input port 14 is arranged above the upper cylinder cover 11, and an output port 15 is arranged on the side of the lower cylinder base 12. The activated carbon particles to be dried are added into the inside of the accommodation space 13 through the input port 14 and discharged through the output port 15 on the side after drying. Since the input and output components are necessary and common functions of existing drying equipment, they will not be elaborated here.

[0056] It further includes an exhaust pipe 16 disposed above the upper cylinder cover 11. The air flow carrying moisture output by the material lifting assembly is discharged from the exhaust pipe 16.

[0057] On the basis of the drying equipment introduced previously, the structure and working principle of the turning mechanism are further described in detail. The turning mechanism includes a rotating shaft 21, a turntable 22, a rod 23 connecting the turntable 22, and a plurality of paddles 24 that are horizontally arranged inside the drying cylinder 1. This design aims to further optimize the agitation and drying effects of activated carbon particles, ensuring uniform heating of the particles and structural protection during the drying process.

[0058] Specifically, the turning mechanism includes a rotating shaft 21 horizontally arranged inside the drying cylinder 1, at least three turntables 22 arranged on the rotating shaft 21, several rods 23 connecting the plurality of turntables 22, and multiple groups of paddles 24 arranged at intervals on the outer side surface of the rod 23. The end of the paddle 24 is close to the inner side surface of the drying cylinder 1, and the output end of the driving assembly 5 is connected to the rotating shaft 21;

[0059] Through the cooperation of the driving assembly 5, the rotating shaft 21, and the turntable 22, the paddles 24 on the rod 23 are driven to agitate the activated carbon particles in the drying cylinder 1. The paddle 24 near the input port 14 is inclined from the input port 14 towards the output port 15, and the paddle 24 near the output port 15 is horizontally arranged.

[0060] Since this equipment is usually a large-scale equipment, at least three turntables 22 are connected. The cooperation strength of other rods 23 can be improved by connecting other rods 23 through the turntable 22.

[0061] The rod 23 connects multiple turntables 22 to form a stable turning structure. The paddle 24 is arranged on the outer side surface of the rod 23, and multiple paddles 24 are arranged at intervals and are close to the inner side surface of the drying cylinder 1. The main function of the paddle 24 is to agitate the activated carbon particles in the drying cylinder 1 when the rotating shaft 21 rotates, so that the particles are continuously turned over and loosened, ensuring uniform heating of the particle surface.

[0062] The paddle 24 near the input port 14 is designed to be inclined from the input port 14 towards the output port 15, while the paddle 24 near the output port 15 is horizontally arranged. The purpose of this design is to achieve better control of particle flow during the drying process:

[0063] When the activated carbon particles enter the drying cylinder 1 through the input port 14, the inclined paddle 24 can help the particles smoothly enter the inside of the drying cylinder 1, and at the same time, use the inclined angle to gradually move the particles towards the middle of the drying cylinder 1 to prevent the particles from accumulating near the input port 14.

[0064] In the middle and rear sections of the drying cylinder 1, the horizontal arrangement of the paddles 24 can slow down the flow rate of the particles towards the outlet 15, ensuring that the particles have sufficient residence time in the drying cylinder 1 to complete sufficient drying. At the same time, the horizontally arranged paddles 24 can stir the particles more evenly, preventing uneven drying caused by the rapid flow of the particles.

[0065] Among them, the inclination angle of the partially inclined paddle 24 is 30° - 60°. In this embodiment, the inclination angle of the paddle 24 is 40°.

[0066] Through the cooperation of the rotating shaft 21, the turntable 22 and the paddle 24, the activated carbon particles can be sufficiently stirred inside the drying cylinder 1. The combined use of the inclined and horizontal paddles 24 ensures more uniform fluidity and distribution of the particles during the drying process, thereby improving the drying effect.

[0067] The design of the inclined paddle 24 helps the particles smoothly enter the inside of the drying cylinder 1 and gradually move forward, while the horizontal paddle 24 ensures that the particles do not flow too quickly towards the outlet 15 in the final stage of drying. This design can prevent the particles from accumulating or having poor flow in the drying cylinder 1, thus optimizing the drying process.

[0068] The design of low-speed stirring, combined with the inclined and horizontal angles of the paddle 24, ensures that the activated carbon particles will not be subject to excessive mechanical friction and impact during the drying process, effectively protecting their microporous structure and maintaining high adsorption performance.

[0069] On the basis of the foregoing solution, the structural design of the lower cylinder base 12 is further described in detail, especially the configuration of the first bottom plate 121, the second bottom plate 122 and the air cavity 123. This design aims to optimize the air flow distribution and the lifting effect of the activated carbon particles during the drying process, ensuring uniform heating of the particles during drying. Specifically:

[0070] The lower cylinder base 12 includes a first bottom plate 121 for receiving the activated carbon particles, and the air outlet holes 31 are arranged on the first bottom plate 121;

[0071] A second bottom plate 122 is arranged below the first bottom plate 121, and the first bottom plate 121 and the second bottom plate 122 form a sealed air cavity 123;

[0072] The air outlet of the fan 32 is inserted into the second bottom plate 122 and is communicated with the air cavity 123.

[0073] When in use, the first bottom plate 121 is the main surface for receiving the activated carbon particles, and the air outlet holes 31 are evenly arranged on the first bottom plate 121. When the fan 32 is started, the airflow enters the interior of the drying cylinder 1 through the air outlet holes 31. The position and number of these air outlet holes 31 are carefully designed to ensure that the airflow can be evenly distributed, so that the activated carbon particles are evenly lifted during the drying process and the heating area of ​​the particles is increased.

[0074] The second bottom plate 122 is disposed below the first bottom plate 121, and a sealed air cavity 123 is formed therebetween. The design of the air cavity 123 allows the airflow from the fan 32 to be evenly distributed in the air cavity 123 before entering the air outlet 31, which helps to prevent the airflow from being too strong or too weak in certain areas, thereby achieving airflow balance in the drying cylinder 1.

[0075] The air outlet of the fan 32 is directly inserted into the second bottom plate 122 and communicates with the air cavity 123. With this design, the fan 32 can continuously and stably inject air into the air cavity 123 and evenly transport the air upward to the drying cylinder 1 through the air outlet 31. This not only helps to maintain a suitable air flow speed inside the drying cylinder 1, but also effectively lifts the activated carbon particles at the bottom to prevent the particles from accumulating at the bottom.

[0076] It should be emphasized that the air outlet of the fan 32 and the area inserted into the second bottom plate 122 are sealed.

[0077] By providing a sealed air cavity 123 between the first bottom plate 121 and the second bottom plate 122, the airflow of the fan 32 can be evenly distributed before entering the drying cylinder 1. This can prevent the airflow from being concentrated in a certain place, resulting in excessive or insufficient local drying, thereby achieving airflow balance in the entire drying cylinder 1 and improving the drying effect.

[0078] Since the air outlet holes 31 are distributed on the first bottom plate 121 receiving the activated carbon, the airflow can directly act on the activated carbon particles at the bottom. In conjunction with the aforementioned material turning mechanism, the airflow can better lift and stir the particles, prevent the particles from accumulating at the bottom of the drying cylinder 1, and ensure that each part of the particles is evenly heated.

[0079] Uniform airflow distribution not only improves drying efficiency, but also avoids friction and collision of particles caused by uneven airflow, thereby protecting the microporous structure of activated carbon. The gentle lifting effect of the airflow keeps the particles in a relatively stable state during the drying process, reducing physical damage.

[0080] By optimizing the airflow path and evenly distributing the air, the fan 32 can achieve efficient airflow control at lower power, thereby reducing the energy consumption of the equipment. In addition, this design also reduces airflow loss, so that the equipment can still achieve an ideal drying effect at a relatively low wind speed.

[0081] Based on the previous design of the air flow system, the design of the material lifting component is further optimized, with a focus on adding the flexible sleeve 33 structure. The function of the flexible sleeve 33 is to prevent the activated carbon particles from blocking the air outlet holes 31 through physical protection measures, so as to maintain the normal operation of the drying system and ensure the stable output of the air flow. Specifically:

[0082] The material lifting component further includes a flexible sleeve 33 embedded in the corresponding side grooves inside the air outlet holes 31. A through hole 333 is provided in the middle of the flexible sleeve 33. When the air flow is output, the through hole 333 is opened, and when the air flow stops outputting, the through hole 333 is closed.

[0083] The flexible sleeve 33 includes a positioning part 331 inserted into the first bottom plate 121 and a guiding part 332 for the local air outlet holes 31. The width of the guiding part 332 gradually decreases from bottom to top. Through the cooperation of the positioning part 331 and the guiding part 332, the activated carbon particles are blocked from blocking the air outlet holes.

[0084] The flexible sleeve 33 is fixed by the cooperation of the positioning part 331 and the corresponding side grooves inside the air outlet holes 31, and the middle part of the air outlet holes is filled by the guiding part 332 to prevent the activated carbon particles from blocking the air outlet holes.

[0085] Among them, the flexible sleeve 33 is made of silica gel material. When the air flow is output, the through hole 333 is deformed and opened under the impact, and when the air flow stops outputting, the through hole 333 resets and closes.

[0086] Since the flexible sleeve 33 is embedded inside the air outlet holes 31 and has a through hole 333 in the middle. When the fan 32 starts and outputs air flow, the air flow is released through the through hole 333, and the through hole 333 will automatically open with the output of the air flow. When the air flow stops, the through hole 333 of the flexible sleeve 33 will close, preventing the activated carbon particles from entering the air cavity 123 through this hole and avoiding the blockage problem.

[0087] Since the flexible sleeve 33 includes a positioning part 331 inserted into the first bottom plate 121 and a guiding part 332 located at the local air outlet holes 31. The positioning part 331 fixes the flexible sleeve 33 firmly in the side grooves of the first bottom plate 121 to ensure that it will not be displaced under the action of the air flow. The design of the guiding part 332 is conical, and its width gradually decreases from bottom to top. This structural design of the guiding part 332 can effectively guide the air flow and at the same time fill the middle gap of the air outlet holes to prevent the activated carbon particles from entering the air outlet holes 31 and causing blockage.

[0088] When in the air flow output state, the through holes 333 of the flexible sleeve 33 are opened, and the air flow enters the inside of the drying cylinder 1 from the air cavity 123 below the bottom plate through the through holes 333, agitating and drying the activated carbon particles. When the air flow stops, the through holes 333 are closed. With the design of the positioning portion 331 and the guiding portion 332, it effectively prevents the particles from blocking the air outlet holes.

[0089] The main advantage of this solution is that through the structure of the flexible sleeve 33, especially the opening and closing function of the through holes 333, it effectively prevents the activated carbon particles from blocking the air outlet holes. Traditional drying equipment often faces the problem of particle blockage, which affects the air flow output and reduces the drying efficiency. This solution automatically controls the opening and closing of the air holes through the flexible sleeve 33, preventing particles from entering the air cavity 123, thereby maintaining the stable operation of the drying system.

[0090] A turning mechanism is arranged inside the drying cylinder 1. The turning mechanism includes a rotating shaft 21 rotatably installed inside the drying cylinder 1.

[0091] A heat source assembly is further introduced. The activated carbon particles are directly heated by the first heating assembly installed on the rotating shaft 21. This design closely cooperates with the turning mechanism and the previous air flow system, making the drying process more efficient and further optimizing the heating and drying effect of the activated carbon particles. Specifically:

[0092] The heat source assembly includes:

[0093] The first heating assembly arranged on the rotating shaft 21. The first heating assembly includes:

[0094] Several groups of support rods 41 inserted on the rotating shaft 21. Several groups of heating rods 42 are horizontally inserted between multiple support rods 41 in the same group. The heating rods 42 are electrically connected to the outside.

[0095] It also includes a control module 7. The control module 7 is electrically connected to the heating rods 42 and the turning mechanism.

[0096] Through the cooperation of the control module 7 and the material turning mechanism, the activated carbon particles are agitated, and the activated carbon particles are heated by the heating rods 42.

[0097] The heating rods 42 are connected to an external power supply, and heat energy is provided inside the drying cylinder 1 by means of electric heating.

[0098] Among them, when the flipping mechanism rotates, in cooperation with the control module 7, the power supply of the heating rod 42 is turned on to make it in a heating state. The heating rod 42 is installed between the support rods 41 and is close to the agitation area of the activated carbon particles. When the flipping mechanism agitates the activated carbon particles, the heating rod 42 provides uniform heat to directly heat the particles, improving the drying efficiency. The setting of the heating rod 42 ensures that the heat can directly act on the surface of the particles, enabling the particles to be evenly heated during the flipping process.

[0099] The heating rod 42 is directly installed on the rotating shaft 21 inside the drying cylinder 1 and is close to the agitation path of the activated carbon particles. Through this design, heat energy can be efficiently transferred to the activated carbon particles, reducing heat energy loss and significantly improving the drying efficiency. Compared with the traditional method that only relies on external heat sources, this internal heating method is more direct and effective.

[0100] The power supply mode of the heat source component is further optimized. By setting a power supply component on the rotating shaft 21, it is ensured that the heating rod 42 can continuously and stably obtain power supply during operation. This design closely cooperates with the previous heating component, flipping mechanism, and control module 7 to improve the stability and operation efficiency of the entire system. Specifically, it also includes the power supply component, and the power supply component includes:

[0101] A conductive rod 44 embedded at one end of the rotating shaft 21 away from the drive component 5;

[0102] A conductive slip ring 43 provided at one end of the rotating shaft 21 facing the conductive rod 44. The conductive rod 44 is inserted into the conductive slip ring 43, and the conductive slip ring 43 is electrically connected to the control module 7 and an external power supply.

[0103] It also includes several groups of conductive wires 45 embedded inside the rotating shaft 21. The conductive wires 45 are electrically connected to the conductive slip ring 43, and the conductive wires 45 extend into the rod member 23 and are electrically connected to the heating rod 42.

[0104] The conductive rod 44 is embedded at one end of the rotating shaft 21 away from the drive component 5, and the conductive slip ring 43 is provided at one end of the rotating shaft 21 facing the conductive rod 44. The conductive rod 44 is inserted into the conductive slip ring 43 and is electrically connected to the control module 7 and the external power supply through the slip ring. Through this design, even if the rotating shaft 21 rotates during operation, the power can still be transferred to the heating rod 42 through the conductive slip ring 43.

[0105] Through several groups of conductive wires 45 embedded inside the rotating shaft 21, these conductive wires 45 are connected to the conductive slip ring 43 and extend along the rotating shaft 21 to the heating rod 42 in the support rod 41, thereby providing power supply for the heating rod 42.

[0106] The power supply component ensures that the heating rod 42 continuously obtains power when the rotating shaft 21 rotates, enabling the heating rod 42 to operate stably and being adjusted by the control module 7. The heat generated by the heating rod 42 is combined with the agitation function of the flipping mechanism to achieve uniform heating of the activated carbon particles.

[0107] When the flipping mechanism rotates, the control module 7 cooperates with the control module 7 to connect the power supply of the heating rod 42 and make it in a heating state. It not only controls the heating state of the heating rod 42 but also manages the power distribution of the power supply system to ensure that each component operates in the best state. In this way, the heating rod 42 can continuously provide uniform and stable heat throughout the drying process, while agitating the particles in cooperation with the flipping mechanism to achieve uniform drying.

[0108] A number of air outlet holes 31 are provided at the inner bottom of the drying cylinder 1, and a blower 32 is provided below the drying cylinder 1. The output port 15 of the blower 32 communicates with the inside of the drying cylinder 1 through the air outlet holes 31. In this embodiment, 40 air outlet holes 31 are arranged in each row, and the number of holes can be adjusted in other embodiments.

[0109] Among them, the conductive slip ring 43, also known as a collector ring or rotary joint, is an electrical device used to transmit power and signals between a fixed part and a rotating part. The conductive slip ring 43 allows the device to continuously transmit current, data, or signals while rotating without power interruption, so it is widely used in systems that require 360-degree continuous rotation and need power or signal transmission, such as rotating cameras, wind turbines 6, robots, medical devices, and automation devices.

[0110] The working principle of the conductive slip ring 43 is based on the process of electrical contact to transmit current or signals:

[0111] When current or signals are transmitted from the fixed part (stator) to the rotating part (rotor), the current is transmitted to the slip ring through the brush. Since physical contact is always maintained between the brush and the slip ring, the current can be continuously transmitted without being affected by the rotation angle.

[0112] As the rotor rotates, the brush slides on the surface of the slip ring. However, due to the use of highly conductive and wear-resistant materials, the contact resistance remains low, and the electrical loss generated by friction is also small.

[0113] The conductive slip ring 43 enables the device to maintain electrical connection while rotating infinitely, without interrupting signals or power transmission due to cable winding or wear.

[0114] Further optimize the material lifting component arranged below the drying cylinder 1, aiming to lift the activated carbon particles by means of air flow, and at the same time, combined with the heating effect of the second heating component, so that the particles can be heated more evenly and effectively inside the drying cylinder 1. This design is closely combined with the previous heating component, flipping mechanism and power supply system, further improving the drying efficiency and the comprehensive performance of the system. Specifically: The material lifting component includes:

[0115] A second heating component arranged between the output port 15 of the fan 32 and the air outlet holes 31. The second heating component includes:

[0116] A top connecting rod arranged above the output port 15 of the fan 32, and a heating plate 46 vertically arranged above the support rod 41. The heating plate 46 is larger than the size of the output port 15, and the heating plate 46 is electrically connected to the control module 7 and an external power supply.

[0117] The heating direction of the heating plate 46 faces the side of the drying cylinder 1. The heating plate 46 includes a heating part 461 in the middle and a heat conducting part 462 surrounding the edge of the heating part 461. The thickness gradually decreases from the heating part 461 towards the heat conducting part 462.

[0118] By arranging a number of air outlet holes 31 at the bottom inside the drying cylinder 1, the fan 32 is installed below the drying cylinder 1, and its output port 15 introduces air flow into the inside of the drying cylinder 1 through the air outlet holes 31. The air flow enters the cylinder through the air outlet holes 31, causing the activated carbon particles to be lifted, thereby increasing the contact area between the particles and the heat source and improving the drying efficiency.

[0119] By arranging the second heating component between the output port 15 of the fan 32 and the air outlet holes 31, including a top connecting rod and a heating plate 46. The heating plate 46 is larger than the size of the output port 15, which can ensure that the air flow is fully heated before entering the drying cylinder 1, thereby increasing the temperature of the air flow and further enhancing the drying effect.

[0120] By vertically installing the heating plate 46 on the support rod 41, with the heating direction facing the side of the drying cylinder 1. The heating plate 46 includes a heating part 461 in the middle and a heat conducting part 462 surrounding the edge of the heating part 461. The thickness of the heat conducting part 462 gradually decreases outward from the heating part 461. This design enables the heating plate 46 to conduct heat to the outside through the heat conducting part 462 while ensuring strong heating in the central part, thereby providing a more uniform heat distribution.

[0121] The air flow output by the blower 32 is heated by the heating plate 46. When these heated air flows enter the drying cylinder 1 through the air outlet holes 31, the heat can be transferred to the activated carbon particles more efficiently. In cooperation with the previous flipping mechanism and the heating rod 42, the activated carbon particles can be quickly and evenly dried under the multiple actions of being lifted, flipped, and heated.

[0122] The material lifting assembly lifts the activated carbon particles through the air flow, enabling the particles to be suspended in the drying cylinder 1, thereby increasing the contact time and contact area between the particles and the heat source. In cooperation with the uniform heating of the heating plate 46, the particles can be heated more evenly throughout the drying cylinder 1, reducing the phenomenon of uneven drying.

[0123] The second heating assembly preheats the air flow through the heating plate 46, making the air flow entering the drying cylinder 1 at a higher temperature and the heat transfer more effective. The heated air flow acts on the particles immediately after entering the drying cylinder 1, significantly improving the overall drying efficiency.

[0124] It should be emphasized that the driving assembly 5 is a motor 6 that drives the rotation of the rotating shaft 21, and the control module 7 is an integrated electronic control system, mainly composed of a microcontroller unit (MCU), a circuit board (PCB), a sensor interface module, a power management unit (PMU), a driving circuit, a communication interface, etc.

[0125] The control module 7 works in coordination with various electrical appliances in the system through the driving circuit and sensor inputs to achieve precise control of the entire drying process. The following is its coordinated control method with key electrical appliances:

[0126] The control module 7 sends control signals to the driving assembly 5 through the driving circuit, usually PWM signals or voltage signals, for adjusting the rotation speed and direction of the motor 6. When the system needs to flip the activated carbon particles, the control module 7 will determine the operating state of the driving motor 6 according to the real-time data fed back by the sensors (such as the distribution of the particles). The control module 7 will issue instructions to start or stop the driving assembly 5 and adjust the movement frequency and strength of the flipping mechanism.

[0127] The control module 7 controls the on-off state of the heating assembly through a relay or SCR connected to the heating assembly, and controls the heating power by adjusting the voltage or current. The control module 7 dynamically adjusts the heating power of the first heating assembly according to the feedback of the temperature sensor inside the drying cylinder 1. If the temperature is lower than the set value, the control module 7 will increase the heating power of the heating rod 42; otherwise, it will reduce the power or turn off the heating rod 42.

[0128] Similar to the control of the first heating assembly, the control module 7 controls the heating degree of the heating plate 46 by adjusting the current of the heating plate 46 and ensures that the heating plate 46 can evenly heat the air flow entering the drying cylinder 1.

[0129] The control module 7 adjusts the voltage of the blower 32 or controls the rotation speed of the blower 32 through a PWM signal, thereby adjusting the intensity of the air flow. According to the feedback from the humidity sensor or temperature sensor in the drying cylinder 1, the control module 7 can determine the operating speed and air volume of the blower 32. When more air flow is required, the module increases the rotation speed of the blower 32; when the drying is coming to an end or the temperature needs to be reduced, the module will reduce the rotation speed of the blower 32. Since the simplest solution of this scheme does not need to cooperate with various types of sensors of other upgrade schemes and only needs to be simply powered on, various sensors are not described in the figure.
