Description

Technical Field

[0001] This utility model relates to the field of powdered activated carbon regeneration technology, specifically a device for regenerating powdered activated carbon after decolorization with high-temperature natural alkali solution. Background Technology

[0002] Powdered activated carbon is made from high-quality wood chips, coconut shells, and coal through a series of production processes. It has the advantages of fast filtration speed, good adsorption performance, strong decolorization and deodorization capabilities, and is economical and durable. The product is widely used in the food, beverage, pharmaceutical, tap water, sugar, and oil industries. It is also commonly used in brewing, sewage treatment, power plants, and electroplating. Activated carbon regeneration equipment is a special equipment used to treat saturated waste activated carbon to restore its adsorption performance and achieve recycling.

[0003] The existing activated carbon powder thermal regeneration equipment works by using high temperature under inert gas protection to remove pollutants adsorbed in the pores of powdered activated carbon through volatilization, decomposition, or carbonization, while restoring the microporous structure and adsorption activity of the activated carbon, thus achieving recycling. In this equipment, the rotating cylinder carrying the activated carbon powder is the core component. Its working environment is characterized by high temperature, abrasion, and corrosion, and its performance is prone to degradation after long-term operation. If not repaired in time, it will affect the regeneration effect and even cause safety hazards. However, the rotation of the cylinder depends on external support components such as rollers, retaining rollers, and drive gears. These components are rigidly connected to the cylinder by bolts or welding. During maintenance, the transmission components such as the roller assembly, reducer, and motor must be removed first to expose the cylinder body, which increases the difficulty of operation and time cost, thus affecting the maintenance or replacement of the cylinder.

[0022] Please see Figure 1-4A high-temperature natural alkali solution decolorization powdered activated carbon regeneration device includes a bottom furnace 1, a top furnace 19, and a material cylinder 2. The top furnace 19 is openable and closable and mounted on the bottom furnace 1. Both the bottom furnace 1 and the top furnace 19 are equipped with heating mechanisms 3 surrounding the material cylinder 2. The bottom furnace 1 is equipped with a mounting frame 6, and a top frame 7 is detachably mounted on the mounting frame 6. Both the mounting frame 6 and the top frame 7 have internal limiting support frames 8 that cooperate with each other and provide rotational support for the material cylinder 2. The mounting frame 6 has internal mechanisms for driving the material cylinder. The rotating mechanism for the cylinder 2 includes gear 12, gear 14, and a drive motor 16. A control terminal 4 is installed on the bottom furnace 1. Guide bars 5 are spirally arranged inside the cylinder 2. The bottom furnace 1 is the basic load-bearing structure of the device. The top furnace 19 is closable and can be installed on the bottom furnace 1. Together, they form the main frame of the equipment, creating a closed heat regeneration space to provide a high-temperature reaction environment for the cylinder 2. The closable design of the top furnace 19 and the bottom furnace 1 facilitates the installation, maintenance, and replacement of the cylinder 2, allowing for efficient material handling. The cylinder 2 is easier to maintain. As the core load-bearing component, the cylinder 2 contains the powdered activated carbon to be regenerated. The spiral guide strip 5 inside the cylinder 2 rotates with it, pushing the activated carbon powder to move axially, ensuring uniform heating of the material and avoiding local accumulation or overheating. Both the bottom furnace 1 and the top furnace 19 are equipped with heating mechanisms 3 surrounding the cylinder 2. Through continuous heating, the inside of the cylinder 2 reaches the required high temperature, meeting the temperature conditions required for the thermal regeneration of activated carbon powder, and promoting the volatilization, decomposition, or carbonization of pollutants adsorbed in the pores. The control terminal 4 is used to integrate and control parameters such as the temperature of the heating mechanism 3, the speed of the rotating mechanism, and the equipment running time, realizing automated regulation and ensuring that the regeneration process is stable and controllable. The mounting frame 6 is fixed on the bottom furnace 1, and the top frame 7 is detachably mounted on the mounting frame 6. Together, they provide the mounting foundation for the limiting support frame 8 and the rotating mechanism. The "detachable" design of the top frame 7 simplifies the maintenance process of the limiting support frame 8 and the cylinder 2, allowing the internal components to be exposed without removing the overall frame.

[0023] Please see Figure 3 and Figure 4 The limiting support frame 8 has a limiting groove 9 inside, and both ends of the material cylinder 2 are provided with limiting blocks 10 that cooperate with the limiting groove 9. Multiple sets of universal balls 11 that rotatably contact the outside of the material cylinder 2 are provided on the limiting support frame 8. The limiting support frame 8 restricts the axial displacement of the material cylinder 2 by cooperating with the limiting blocks 10 of the material cylinder 2 through the internal limiting groove 9, ensuring that the position of the material cylinder 2 is stable during high-temperature rotation, avoiding uneven heating or equipment collision due to displacement, and providing stable rotation support. The rotatable universal balls 11 on the limiting support frame 8 contact the outside of the material cylinder 2, which not only bear the radial support force of the material cylinder 2, but also reduce the resistance of the material cylinder 2 during rotation through rolling friction, reduce the wear of the limiting support frame 8 and the material cylinder 2, extend the service life of the components, and ensure smooth rotation of the material cylinder 2.

[0024] Please see Figure 3 and Figure 4 The material cylinder 2 has multiple sets of gears 12 on its exterior. A rotating rod 13 is rotatably mounted inside the mounting frame 6. A gear 14 meshes with gear 12 on the rotating rod 13. A sprocket 15 is mounted on the rotating rod 13. A drive motor 16 is located inside the mounting frame 6. A sprocket 17 is mounted at the output end of the drive motor 16, and the sprocket 17 is connected to the sprocket 15 via a chain 18. Gear 12 transmits rotational power to the material cylinder 2 by meshing with gear 14, driving it to rotate. The rotating rod 13, through gear 14 and gear 12... The drive motor 16 transmits power to the material cylinder 2. Gear 14 meshes with gear 12 on the material cylinder 2 to transmit power. The gear ratio can adjust the rotation speed of the material cylinder 2 to adapt to the regeneration requirements of different activated carbon powders. The drive motor 16 is the power source. Through the sprocket 17 and chain 18 at the output end, it is connected to the sprocket 15 on the rotating rod 13 to transmit power to the rotating rod 13, which ultimately drives the material cylinder 2 to rotate. The sprocket 15, sprocket 17, and chain 18 constitute a chain drive mechanism to realize the power transmission between the drive motor 16 and the rotating rod 13.

[0025] Working principle: First, the top furnace 19 and the bottom furnace 1 are closed to form a closed thermal regeneration space. The powdered activated carbon to be regenerated enters the inside of the cylinder 2 through one end. Parameters such as the temperature of the heating mechanism 3, the speed of the rotating mechanism, and the equipment running time are set via the control terminal 4. The heating mechanism 3 on the bottom furnace 1 and the top furnace 19 begins to heat the outside of the cylinder 2, bringing the inside of the cylinder 2 to the high temperature conditions required for the thermal regeneration of the activated carbon powder. This causes the pollutants adsorbed in the pores of the activated carbon to volatilize, decompose, or carbonize. During the heating process, the drive motor 16 starts, and its output sprocket 17 drives the sprocket 15 on the rotating rod 13 to rotate via the chain 18. The rotating rod 13 rotates accordingly, driving the gear 14 on it to rotate. The gear 14 rotates with the outside of the cylinder 2. The gear 12 meshes and transmits power to the cylinder 2, driving the cylinder 2 to rotate. When the cylinder 2 rotates, the guide bar 5 with a spiral inside pushes the activated carbon powder to move axially, ensuring that the material is heated evenly and avoiding local accumulation or overheating. At the same time, the limiting support frame 8 inside the mounting frame 6 and the top frame 7 provides stable support for the cylinder 2. The limiting support frame 8 cooperates with the limiting blocks 10 at both ends of the cylinder 2 through the limiting groove 9 inside, limiting the axial displacement of the cylinder 2. The universal ball bearings 11 on the limiting support frame 8 contact the outside of the cylinder 2, bear the radial support force and reduce the rotational resistance through rolling friction, ensuring that the cylinder 2 rotates smoothly. When it is necessary to disassemble and repair the cylinder 2, simply open the top furnace 19 and remove the top frame 7 to take the cylinder 2 out of the furnace body.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
