Description

Technical Field

[0001] This utility model relates to the field of activated carbon processing technology, and in particular to an activated carbon layer hot air drying assembly. Background Technology

[0002] Activated carbon is a specially treated type of carbon. Organic raw materials (fruit shells, coal, wood, etc.) are heated in the absence of air to reduce non-carbon components (this process is called carbonization). Then, they react with gases, and the surface is eroded, creating a structure with well-developed micropores (this process is called activation). Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, which results in countless tiny pores on the surface of activated carbon. The diameter of the micropores on the surface of activated carbon is mostly between 2 and 50 nm. Even a small amount of activated carbon has a huge surface area. Almost all applications of activated carbon are based on this characteristic.

[0003] In the activated carbon production process, the activated carbon after alkali washing usually has a moisture content of about 70%, while the process requires the activated carbon to have a moisture content of 10%. Therefore, the activated carbon product needs to be dried. The activated carbon drying equipment currently used usually introduces hot air from the bottom to dry the activated carbon piled up on top. When the activated carbon is piled up, it is difficult for the hot air to dry all the activated carbon evenly. If the activated carbon is poured in in batches in small amounts for drying, the drying time is too short, resulting in poor drying effect. Moreover, the existing drying system cannot recycle heat and resources, resulting in low thermal efficiency and resource waste.

[0004] A search revealed that Chinese utility model patent CN217715760U discloses a hot air drying component for activated carbon layers, belonging to the field of activated carbon processing technology. To address the problem of incomplete turning during activated carbon drying, leading to poor drying results, a metal mesh wall is installed between the front and rear plates. This metal mesh wall allows hot air to circulate throughout the rotating mechanism, improving contact between the hot air and the activated carbon, thus enhancing drying efficiency. Inside the metal mesh wall are turning blades, with spiral blades arranged at intervals. This spiral arrangement allows the rotating blades to turn and transport the activated carbon, turning the inner and bottom activated carbon to the outer layer during drying. This ensures uniform drying of both inner and outer activated carbon. Furthermore, the rotation increases the spacing between the activated carbon layers, increasing contact with hot air and improving drying efficiency.

[0005] However, the above-mentioned device has at least the following technical defects:

[0006] 1. The above-mentioned device uses a flipping mechanism to stir the activated carbon, thereby achieving the purpose of drying the surface of the activated carbon by air. However, the above method will cause a large amount of dust to be generated when the activated carbon is stirred, which will cause pollution to the environment.

[0007] 2. The hot air distribution of the hot air blower may not be uniform enough, causing the carbon layer in some areas to dry faster than in other areas, affecting the overall drying effect.

[0008] 3. The above-mentioned device has a relatively complex structure, including multiple components such as a drying drum, a tilting mechanism, a motor, a hot air blower, and an electric telescopic rod, which increases manufacturing and maintenance costs. Utility Model Content

[0009] This invention addresses the shortcomings of existing technologies by providing an activated carbon layer hot air drying component, effectively solving the technical problems existing in the prior art.

[0010] To solve the above problems, the technical solution adopted by this utility model is: an activated carbon layer hot air drying assembly, including a drying box, a door hinged to one side of the outer surface of the drying box, a support frame installed at the bottom of the drying box, a transmission mechanism installed on the box body; a reciprocating mechanism installed inside the drying box, the reciprocating mechanism being driven by the transmission mechanism to move back and forth; a blower mechanism installed on the top of the drying box; and an exhaust pipe installed on the outer surface of the drying box.

[0011] Preferably, the blowing mechanism includes air holes opened on the drying box, an air hood installed on the inner wall of the air holes, an air heater installed on the top of the air hood, and a blower installed on the top of the air heater.

[0012] Preferably, a motor is installed on one side of the drying chamber, and a first gear is coaxially fixed to the output end of the motor. A second gear meshes with the outer surface of the first gear. The first gear and the second gear are rotatably connected to the top of the drying chamber, and a cam is coaxially fixed to the top of the second gear.

[0013] Preferably, the two ends of the inner wall at the bottom of the drying oven are fixedly connected to support seats, and the top of the support seats is fixedly connected to limit plates. The reciprocating mechanism includes a tray, and the front and rear outer surfaces of the tray are respectively fixedly connected to limit blocks adapted to the limit plates. A partition is provided between the reciprocating mechanism and the transmission mechanism. A limit groove is opened on the partition. A connecting rod adapted to the limit groove is fixedly connected to the end of the tray near the transmission mechanism. A hinge rod is hinged to the non-center position of the top of the cam. The hinge rod and the connecting rod are detachably connected by bolts.

[0014] Preferably, a through groove is formed on the outer surface of the support base.

[0015] Preferably, the upper surface of the tray is evenly distributed with air holes.

[0016] This utility model has a novel structure, ingenious design, and is simple and convenient to operate. Compared with the prior art, it has the following advantages:

[0017] 1. This device provides hot air through a blower mechanism, which can quickly increase the temperature inside the drying chamber, accelerate the evaporation of moisture in the activated carbon layer, and improve drying efficiency. The reciprocating motion of the tray ensures that the activated carbon layer is heated evenly, avoiding local overheating or uneven drying, and further improving the drying effect.

[0018] 2. The device provides stable support and guidance for the reciprocating motion of the pallet through the setting of the support base and the limiting plate, ensuring that the pallet will not deviate or shake during the movement, thus guaranteeing the stability and reliability of the device.

[0019] 3. The hinge rod and connecting rod of this device are detachably connected by bolts, which facilitates disassembly and maintenance when needed. If a component fails, it can be replaced individually, reducing maintenance costs.

[0020] 4. The tray of this device has evenly distributed air holes on its upper surface, which allows hot air to better contact the activated carbon layer and improve the drying effect. At the same time, the exhaust pipe can promptly remove the water vapor generated during the drying process from the drying chamber, maintain air circulation in the drying chamber, and facilitate the continuous drying process.

Detailed Implementation

[0026] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0027] like Figure 1-4 As shown, this utility model provides a hot air drying assembly for activated carbon layers, including a drying chamber 1, a door 2 hinged to one side of the outer surface of the drying chamber 1, a support frame 6 installed at the bottom of the drying chamber 1, a transmission mechanism 4 installed on the chamber 1, a reciprocating mechanism 3 installed inside the drying chamber 1 and driven by the transmission mechanism 4 to move back and forth, a blower mechanism 5 installed on the top of the drying chamber 1, and an exhaust pipe 7 installed on the outer surface of the drying chamber 1.

[0028] Preferably, the blower mechanism 5 includes an air hole 13 opened on the drying box 1, an air hood 10 installed on the inner wall of the air hole 13, an air heater 9 installed on the top of the air hood 10, and a blower 8 installed on the top of the air heater 9.

[0029] Preferably, a motor 20 is installed on one side of the drying chamber 1. A first gear 21 is coaxially fixed to the output end of the motor 20. A second gear 22 meshes with the outer surface of the first gear 21. The first gear 21 and the second gear 22 are rotatably connected to the top of the drying chamber 1. A cam 23 is coaxially fixed to the top of the second gear 22.

[0030] Preferably, the two ends of the bottom inner wall of the drying oven 1 are fixedly connected to support seats 12, and the top of the support seats 12 are respectively fixedly connected to limit plates 15. The reciprocating mechanism 3 includes a tray 11, and the front and rear outer surfaces of the tray 11 are respectively fixedly connected to limit blocks 16 adapted to the limit plates 15. A partition is provided between the reciprocating mechanism 3 and the transmission mechanism 4. A limit groove is opened on the partition. A connecting rod 18 adapted to the limit groove is fixedly connected to one end of the tray 11 near the transmission mechanism 4. A hinge rod 24 is hinged to the non-center position of the top of the cam 23. The hinge rod 24 and the connecting rod 18 are detachably connected by bolts 19.

[0031] Preferably, a through groove 14 is formed on the outer surface of the support base 12.

[0032] Preferably, the upper surface of the tray 11 is evenly distributed with air holes 17.

[0033] The working principle of this device is as follows: When using it, the user first places the activated carbon to be dried in the tray 11, and then starts the blower 8. The blower 8 draws in outside air, which is heated by the air heater 9 and then enters the drying chamber 1 through the air vent 13 and the air hood 10. The heated air provides hot air for drying the activated carbon layer. At the same time, the motor 20 starts, which in turn drives the first gear 21 to rotate. The first gear 21 meshes with the second gear 22, causing the second gear 22 to rotate. The cam 23 at the top of the second gear 22 rotates accordingly. The hinge rod 24, which is hinged at a non-central position of the cam 23, swings with the rotation of the cam 23. The connecting rod 18 is connected to the bolt 19, and the connecting rod 18 is fixed to the tray 11. The tray 11 moves on the support seat through the cooperation of the limiting block 16 and the limiting plate 15. Therefore, under the action of the cam 23 and the hinge rod 24, the tray 11 reciprocates in the drying chamber 1. In general, this device dries the activated carbon layer on the tray 11 by the hot air entering the drying chamber 1 from the blower mechanism 5. During the drying process, the hot air carries water vapor and is discharged from the drying chamber 1 through the exhaust pipe 7. In order to prevent the support seat 12 from blocking the hot air carrying water vapor from being discharged from the drying chamber 1, a ventilation groove 14 is specially opened on the support seat 12.

[0034] This device is simple to operate and easy to use. It provides hot air to the drying chamber by setting up a blower 8 and an air heater 9. The reciprocating mechanism 3 driven by the transmission mechanism 4 shakes the activated carbon placed in the tray 11, thereby turning the activated carbon over and ensuring that the cylindrical surface of the activated carbon particles is heated evenly, thus improving the drying efficiency. The wind hood 10 increases the area of ​​the tray that receives hot air, further accelerating the drying efficiency. As the tray moves back and forth, the activated carbon on the tray is heated more evenly, improving the practicality of the device. The air holes 17 on the tray 11 can better expel moisture, increasing the functionality of the device.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
