[0002] Activated carbon is a porous substance with strong adsorption ability, so it is widely used in fields such as water treatment and air purification. In the production process of activated carbon, drying is a key step. Usually, drying equipment is needed to dry the activated carbon to remove the moisture in it. The heater of the drying equipment is one of the core components of this equipment, and its main function is to provide heat to raise the temperature of the activated carbon in the drying equipment, thereby accelerating the evaporation of moisture.

[0003] In traditional activated carbon drying equipment, the heater is usually designed to be installed outside the drying furnace, and the heat is transferred to the activated carbon particles inside the furnace body by means of heat conduction or heat radiation. Common types of heaters include electric heaters, gas heaters, steam heaters, etc.

[0004] The heater is usually only set outside the furnace body, and the heat needs to be conducted into the interior through the furnace wall. Especially when processing activated carbon particles with special requirements, slow drying is usually required. Since the heater can only play an external heating role, the temperature rise of the internal activated carbon particles is slow, resulting in a slow moisture evaporation rate and a long drying process.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

Based on the embodiments in 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.

[0038] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating 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" means two or more, unless otherwise specifically defined.

[0039] Heaters are usually only installed outside the furnace body, and heat needs to be conducted into the interior through the furnace wall. Especially when processing activated carbon particles with special requirements, slow drying is usually required. Since the heater can only provide external heating, the temperature of the internal activated carbon particles rises slowly, resulting in a slow water evaporation rate and a long drying process. Therefore, a heater for a finished product drying device in activated carbon production is designed to solve the above problems, and the specific solution is as follows:

[0040] Refer to Figure 1-8 As shown, a finished product drying device for activated carbon production includes;

[0041] A drying cylinder 1 for placing the activated carbon particles to be dried;

[0042] A material turning mechanism rotatably arranged inside the drying cylinder 1 and a driving assembly 5 for driving the material turning mechanism to rotate;

[0043] A heat source assembly arranged inside the drying cylinder 1, and the heat source assembly heats the activated carbon particles to be dried;

[0044] A material lifting assembly arranged below the drying cylinder 1, the material lifting assembly is located directly below the material turning mechanism, and the material lifting assembly includes:

[0045] A plurality of air outlet holes 31 arranged at the inner bottom of the drying cylinder 1 and a blower 32 arranged below the drying cylinder 1, and the output port 15 of the blower 32 communicates with the inside of the drying cylinder 1 through the air outlet holes 31;

[0046] 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;

[0047] Through the cooperation of the control module 7 and the material turning mechanism, the activated carbon particles are agitated, and through the cooperation of the air outlet holes 31 and the blower 32, an air flow is output, and the air flow lifts the activated carbon particles located at the inner bottom of the drying cylinder 1.

[0048] By installing the material turning mechanism inside the drying cylinder 1 and rotating it through the driving assembly 5. The material turning mechanism slowly agitates 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.

[0049] 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 heat loss problem 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.

[0050] The material lifting component sends air flow into the interior of the drying cylinder 1 through the air outlet holes 31, causing the activated carbon particles located 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 moisture evaporation can be accelerated. In addition, the combined use of the material lifting component and the material turning mechanism can effectively prevent uneven drying caused by particle accumulation. Through the design of low-speed agitation 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.

[0051] Through the cooperation of the material turning mechanism and the material lifting component, the activated carbon particles can be uniformly heated in the drying cylinder 1, avoiding the drying effect difference caused by uneven temperature distribution in traditional equipment.

[0052] Among them, the drying cylinder 1 includes a lower cylinder base 12 and an upper cylinder cover 11 covering above 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 interior 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.

[0053] It also includes an exhaust pipe 16 arranged above the upper cylinder cover 11. The air flow output by the material lifting component carries moisture and is discharged from the exhaust pipe 16.

[0054] On the basis of the drying equipment introduced before, the structure and working principle of the turning mechanism are further elaborated in detail. The turning mechanism includes a rotating shaft 21 horizontally arranged inside the drying cylinder 1, a turntable 22, a rod 23 connecting the turntable 22, and a plurality of paddles 24. This design aims to further optimize the agitation and drying effect of the activated carbon particles, ensuring the uniform heating of the particles and the protection of the structure during the drying process.

[0055] 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 of the rod 23. The end of the paddle 24 is close to the inner side of the drying cylinder 1. The output end of the driving component 5 is connected to the rotating shaft 21;

[0056] Through the cooperation of the driving component 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.

[0057] Since this device is usually a large-scale device, it is connected to at least three turntables 22. By connecting other rods 23 through the turntables 22 for cooperation, the cooperation strength of other rods 23 can be improved.

[0058] The rod 23 is connected to multiple turntables 22 to form a stable flipping structure. The paddles 24 are arranged on the outer side surface of the rod 23. 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 paddles 24 is to stir the activated carbon particles in the drying cylinder 1 when the rotating shaft 21 rotates, so that they are continuously flipped and loosened, ensuring that the surfaces of the particles are evenly heated.

[0059] 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 such a design is to achieve better control of particle flow during the drying process:

[0060] 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 interior 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, avoiding the accumulation of particles near the input port 14.

[0061] In the middle and rear sections of the drying cylinder 1, the horizontal arrangement of the paddle 24 can slow down the flow rate of the particles towards the output port 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 paddle 24 can stir the particles more evenly, avoiding uneven drying caused by the rapid flow of the particles.

[0062] Among them, the inclination angle of some of the inclined paddles 24 is 30° - 60°. In this embodiment, the inclination angle of the paddle 24 is 40°.

[0063] Through the cooperation of the rotating shaft 21, the turntable 22 and the paddle 24, the activated carbon particles in the drying cylinder 1 can be fully stirred. 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.

[0064] The design of the inclined paddle 24 helps the particles smoothly enter the interior 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 output port 15 in the final stage of drying. This design can prevent the accumulation or poor flow of particles in the drying cylinder 1, thereby optimizing the drying process.

[0065] 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.

[0066] Based on the above - mentioned 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 during the drying process and the lifting effect of activated carbon particles, ensuring uniform heating of the particles during drying. Specifically:

[0067] The lower cylinder base 12 includes a first bottom plate 121 for receiving activated carbon particles, and the air outlet holes 31 are arranged on the first bottom plate 121;

[0068] 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;

[0069] The air outlet of the fan 32 is inserted into the second bottom plate 122 and is in communication with the air cavity 123.

[0070] During use, the first bottom plate 121 is the main surface for receiving 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 air flow enters the drying cylinder 1 through the air outlet holes 31. The positions and quantities of these air outlet holes 31 are carefully designed to ensure that the air flow can be evenly distributed, so as to evenly lift the activated carbon particles during drying and increase the heating area of the particles.

[0071] The second bottom plate 122 is arranged below the first bottom plate 121, and a sealed air cavity 123 is formed between them. The design of the air cavity 123 enables the air flow from the fan 32 to be evenly distributed in the air cavity 123 before entering the air outlet holes 31, which helps to avoid the air flow being too strong or too weak in some areas, thus achieving air - flow balance in the drying cylinder 1.

[0072] The air outlet of the fan 32 is directly inserted into the second bottom plate 122 and is in communication with the air cavity 123. Through this design, the fan 32 can continuously and stably inject air into the air cavity 123 and evenly convey it upward through the air outlet holes 31 into the drying cylinder 1. This not only helps to maintain an appropriate air - flow speed inside the drying cylinder 1, but also effectively lifts the activated carbon particles at the bottom and prevents the particles from accumulating at the bottom.

[0073] It should be emphasized that the area where the air outlet of the fan 32 is inserted into the second bottom plate 122 is sealed.

[0074] By setting a sealed air cavity 123 between the first bottom plate 121 and the second bottom plate 122, the air flow of the fan 32 can be evenly distributed before entering the drying cylinder 1. This can prevent the air flow from concentrating in one place, resulting in local over - drying or under - drying, thus achieving air - flow balance throughout the drying cylinder 1 and improving the drying effect.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] Based on the previous airflow system design, the design of the material lifting component is further optimized, with the focus on adding a flexible sleeve 33 structure. The function of the flexible sleeve 33 is to prevent the activated carbon particles from blocking the air outlet 31 through physical protection measures, thereby maintaining the normal operation of the drying system and ensuring the stable output of the airflow. Specifically:

[0079] The material lifting assembly also includes a flexible sleeve 33 embedded in the corresponding side groove inside the air outlet 31, and a through hole 333 is provided in the middle of the flexible sleeve 33. When the airflow is output, the through hole 333 is opened, and when the airflow stops outputting, the through hole 333 is closed.

[0080] The flexible sleeve 33 includes a positioning portion 331 inserted into the first bottom plate 121 and a guide portion 332 of the local air outlet 31. The width of the guide portion 332 gradually decreases from bottom to top. Through the cooperation of the positioning portion 331 and the guide portion 332, the activated carbon particles are prevented from blocking the air outlet.

[0081] The flexible sleeve 33 is fixed by the positioning portion 331 cooperating with the corresponding side groove inside the air outlet 31, and the middle part of the air outlet is filled by the guide portion 332 to prevent the activated carbon particles from clogging the air outlet.

[0082] The flexible sleeve 33 is made of silicone material. When the airflow is output, the through hole 333 is deformed and opened by impact. When the airflow stops outputting, the through hole 333 is reset and closed.

[0083] Since the flexible sleeve 33 is embedded and installed inside the air outlet hole 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 activated carbon particles from entering the air cavity 123 through this hole and avoiding blockage problems.

[0084] Since the flexible sleeve 33 includes a positioning portion 331 inserted into the first bottom plate 121 and a guiding portion 332 located at the partial air outlet hole 31. The positioning portion 331 fixes the flexible sleeve 33 firmly in the side groove of the first bottom plate 121 to ensure that it will not be displaced under the action of the air flow. The guiding portion 332 is designed to be conical, and its width gradually decreases from bottom to top. This structural design of the guiding portion 332 can effectively guide the air flow and at the same time fill the gap in the middle of the air outlet hole to prevent activated carbon particles from entering the air outlet hole 31 and causing blockage.

[0085] Since in the air flow output state, the through hole 333 of the flexible sleeve 33 is opened, and the air flow enters the drying cylinder 1 from the air cavity 123 below the bottom plate through the through hole 333 to stir and dry the activated carbon particles. When the air flow stops, the through hole 333 closes, and together with the design of the positioning portion 331 and the guiding portion 332, it effectively prevents particles from blocking the air outlet hole.

[0086] 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 hole 333, it effectively prevents activated carbon particles from blocking the air outlet hole. 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 to prevent particles from entering the air cavity 123, thereby maintaining the stable operation of the drying system.

[0087] A turning mechanism is arranged inside the drying cylinder 1, and the turning mechanism includes a rotating shaft 21 rotatably installed inside the drying cylinder 1;

[0088] A heat source component is further introduced, and the activated carbon particles are directly heated by the first heating component 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:

[0089] The heat source component includes:

[0090] The first heating component arranged on the rotating shaft 21, and the first heating component includes:

[0091] Several groups of support rods 41 inserted on the rotating shaft 21, and several groups of heating rods 42 are horizontally inserted between multiple support rods 41 in the same group, and the heating rods 42 are electrically connected to the outside;

[0092] It further includes a control module 7, which is electrically connected to the heating rod 42 and the flipping mechanism;

[0093] 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 rod 42.

[0094] The heating rod 42 is connected to an external power supply, and heat energy is provided inside the drying cylinder 1 by means of electric heating.

[0095] 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, directly heating the particles and 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.

[0096] 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 an external heat source, this internal heating method is more direct and effective.

[0097] The power supply mode of the heat source assembly is further optimized. By setting a power supply assembly on the rotating shaft 21, it is ensured that the heating rod 42 can obtain continuous and stable power supply during operation. This design closely cooperates with the previous heating assembly, flipping mechanism and control module 7, improving the stability and operation efficiency of the entire system. Specifically, it also includes a power supply assembly, and the power supply assembly includes:

[0098] A conductive rod 44 embedded at one end of the rotating shaft 21 away from the drive assembly 5;

[0099] 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.

[0100] It further 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.

[0101] It is embedded in one end of the rotating shaft 21 away from the drive assembly 5 through the conductive rod 44, and the conductive slip ring 43 is arranged 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 transmitted to the heating rod 42 through the conductive slip ring 43.

[0102] A plurality of groups of conductive wires 45 are embedded in 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, so as to provide power supply for the heating rod 42.

[0103] The power supply component ensures that the heating rod 42 continuously obtains power when the rotating shaft 21 rotates, so that the heating rod 42 can work stably and is adjusted by the control module 7. The heat generated by the heating rod 42 is combined with the stirring function of the flipping mechanism to achieve uniform heating of the activated carbon particles.

[0104] When the flipping mechanism rotates, the control module 7 cooperates with the control module 7 to turn on the power supply of the heating rod 42 to 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 during the entire drying process, and at the same time cooperate with the flipping mechanism to stir the particles to achieve uniform drying.

[0105] A plurality of air outlet holes 31 are arranged at the inner bottom of the drying cylinder 1, and a fan 32 is arranged below the drying cylinder 1. The output port 15 of the fan 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.

[0106] Among them, the conductive slip ring 43, also known as a collector ring or a 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, 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.

[0107] The working principle of the conductive slip ring 43 is based on the process of electrically contacting to transmit current or signals:

[0108] 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.

[0109] 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 caused by friction is also small.

[0110] The conductive slip ring 43 enables the device to maintain an electrical connection while rotating infinitely, without interrupting the signal or power transmission due to cable entanglement or wear.

[0111] The material lifting assembly arranged below the drying cylinder 1 is further optimized, aiming to lift the activated carbon particles by means of air flow. At the same time, combined with the heating effect of the second heating assembly, the particles can be heated more evenly and effectively inside the drying cylinder 1. This design is closely combined with the previous heating assembly, flipping mechanism and power supply system, further improving the drying efficiency and the comprehensive performance of the system. Specifically: The material lifting assembly includes:

[0112] The second heating assembly arranged between the output port 15 of the blower 32 and the air outlet holes 31, and the second heating assembly includes:

[0113] A top contact rod arranged above the output port 15 of the blower 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.

[0114] 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 located in the middle and a heat conduction part 462 surrounding the edge of the heating part 461. The thickness gradually decreases from the heating part 461 towards the heat conduction part 462.

[0115] By arranging a number of air outlet holes 31 at the bottom inside the drying cylinder 1, the blower 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.

[0116] The second heating assembly is arranged between the output port 15 of the blower 32 and the air outlet holes 31, and includes a top contact 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.

[0117] The heating plate 46 is vertically mounted on the support rod 41, with the heating direction facing the side of the drying cylinder 1. The heating plate 46 includes a heating portion 461 in the middle and a heat conducting portion 462 surrounding the edge of the heating portion 461, and the thickness of the heat conducting portion 462 gradually decreases from the heating portion 461 to the outside. This design enables the heating plate 46 to conduct heat to the outside through the heat conducting portion 462 while ensuring strong heating of the central portion, thereby providing more uniform heat distribution.

[0118] The airflow output by the fan 32 is heated by the heating plate 46. When the heated airflow enters the drying cylinder 1 through the air outlet 31, the heat can be more efficiently transferred to the activated carbon particles. With the previous flipping mechanism and the heating rod 42, the activated carbon particles can be quickly and evenly dried under the multiple effects of lifting, flipping and heating.

[0119] The material lifting component lifts the activated carbon particles through the airflow, so that the particles can be suspended in the drying cylinder 1, thereby increasing the contact time and contact area between the particles and the heat source. With the uniform heating of the heating plate 46, the particles can be heated more evenly in the entire drying cylinder 1, reducing the phenomenon of uneven drying.

[0120] The second heating component preheats the airflow through the heating plate 46, so that the airflow entering the drying cylinder 1 has a higher temperature and the heat transfer is more effective. The heated airflow immediately acts on the particles after entering the drying cylinder 1, significantly improving the overall drying efficiency.

[0121] It should be emphasized that the drive component 5 is a motor 6 that drives the rotating shaft 21 to rotate, 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 drive circuit, a communication interface, etc.

[0122] The control module 7 works with various electrical appliances in the system through drive circuits and sensor inputs to achieve precise control of the entire drying process. The following is the coordinated control method between the control module and key electrical appliances:

[0123] The control module 7 sends a control signal to the drive component 5 through the drive circuit, usually a PWM signal or a voltage signal, which is used to adjust the 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 drive motor 6 based on the real-time data fed back by the sensor (such as the distribution of the particles). The control module 7 will issue instructions to start or stop the drive component 5, and adjust the movement frequency and strength of the flipping mechanism.

[0124] The control module 7 controls the on-off state of the heating component through a relay or SCR connected to the heating component, and controls the heating power by adjusting the voltage or current. The control module 7 dynamically adjusts the heating power of the first heating component 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.

[0125] Similar to the control of the first heating component, 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.

[0126] 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 of the humidity sensor or temperature sensor inside 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 needed, 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.
