Description

Technical Field

[0001] The utility model belongs to the technical field of activated carbon preparation devices, and particularly relates to an activated carbon impregnation device. Background Art

[0002] Among energy storage materials, porous activated carbon is an ideal energy storage material at present due to its large specific surface area, uniform pore size distribution, adjustable pore structure and other advantages. In addition, due to its uniform pore size distribution, porous activated carbon also has excellent performance in absorbing and storing gases and liquids, and is often used in environmental protection, pharmaceutical and chemical industries as a purification absorbent for toxic gases and liquids. When preparing such activated carbon, the impregnation process is usually used to improve the chemical modification of activated carbon, such as oxidation modification, reduction modification, acid-base modification, metal loading modification and plasma modification.

[0003] Existing impregnation devices usually use a rotating stirring shaft or barrel to improve the impregnation effect. The principle is to stir the activated carbon and the impregnating solution to improve the mixing uniformity of the activated carbon and the impregnating solution, so as to improve the impregnation effect. However, such impregnation methods still cannot improve the impregnation effect in the capillary micropores of activated carbon, and the loading amount of active components in the capillary micropores is still small. Therefore, on the basis of existing impregnation devices, there is still room for improvement in the impregnation effect of activated carbon and the loading amount of active components. Summary of the Utility Model

[0004] To solve the deficiencies of the prior art, the utility model provides an activated carbon impregnation device, which can further improve the impregnation effect of activated carbon and the loading amount of active components on the activated carbon.

[0005] To achieve the purpose of the utility model, the following scheme is proposed:

[0006] An activated carbon impregnation device includes: a tank body, a rotary drum, stirring rods and adjusting rods.

[0007] The tank body is cylindrical, and a discharge pipe is provided at the bottom thereof. A valve is provided on the discharge pipe. A feed pipe and a liquid inlet pipe are provided at the top of the tank body;

[0008] The rotary drum is in a tubular structure, its bottom is sealed, and a connecting pipe is coaxially provided at the top. The rotary drum is coaxially arranged in the tank body, and the connecting pipe vertically passes through the top of the tank body. The rotary drum is rotatably arranged around the axis;

[0009] Stirring rods are penetrated through the side wall of the rotary drum, and their axes intersect with the axis of the rotary drum. A plurality of stirring rods are arranged along the circumferential and axial directions of the rotary drum. A sliding seal is provided between the inner wall of the mounting hole of the rotary drum for penetrating the stirring rods and the outer wall of the stirring rods;

[0010] The adjusting rod is coaxially arranged through the connecting pipe, and the lower end of the adjusting rod extends into the inside of the rotating cylinder. An articulated rod is arranged between the adjusting rod and the stirring rod. The two ends of the articulated rod are respectively hinged to the adjusting rod and the stirring rod, and the axis of the hinge is perpendicular to the axis of the rotating cylinder. The adjusting rod is arranged to move along the axis and drives the stirring rod to move along the axis through the articulated rod.

[0011] The beneficial effects of the present utility model are as follows: The activated carbon is preliminarily impregnated by stirring, and at this time, the impregnation requirements that can be achieved by traditional impregnation equipment can already be met. Then, the stirring rod compresses the space inside the tank body, thereby increasing the pressure inside the tank body, which helps to press the impregnating liquid into the capillary micropores of the activated carbon, thereby improving the impregnation effect of the activated carbon and the loading amount of the active components on the activated carbon.

Detailed Embodiments

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] As Figures 1 to 4 shown, an activated carbon impregnation device includes: a tank body 1, a rotating cylinder 2, a stirring rod 3, and an adjusting rod 4.

[0021] The tank body 1 is cylindrical, and a discharge pipe 11 is provided at the bottom thereof. The discharge pipe 11 is provided with a valve. The valve is in a closed state during the impregnation process, and only the valve needs to be opened for discharge. A feed pipe 12 and a liquid inlet pipe 13 are provided at the top of the tank body 1. The feed pipe 12 is used to add activated carbon into the tank body 1, and the liquid inlet pipe 13 is used to add impregnation liquid.

[0022] The drum 2 is a tubular structure with a sealed bottom and a connecting pipe 21 coaxially arranged on the top. The drum 2 is coaxially arranged in the tank body 1. The connecting pipe 21 vertically passes through the top of the tank body 1. The drum 2 is rotatably arranged around the axis. Specifically, a motor may be provided on the top of the tank body 1. The motor is connected to the connecting pipe 21 by gear transmission or belt transmission, so that the motor is used to drive the connecting pipe 21 to rotate, thereby driving the drum 2 to rotate around the axis.

[0023] A stirring rod 3 is passed through the side wall of the drum 2, and its axis intersects with the axis of the drum 2. Multiple stirring rods 3 are provided along the circumferential direction and axial direction of the drum 2. A sliding seal is provided between the inner wall of the mounting hole of the drum 2 for passing the stirring rod 3 and the outer wall of the stirring rod 3. Specifically, an annular groove can be provided on the outer wall of the stirring rod 3, and a sealing ring can be assembled in the annular groove to achieve the purpose of sliding sealing.

[0024] The adjusting rod 4 is coaxially arranged in the connecting tube 21, and the lower end of the adjusting rod 4 extends to the inside of the rotating drum 2. A hinged rod 5 is provided between the adjusting rod 4 and the stirring rod 3. The two ends of the hinged rod 5 are respectively hingedly connected to the adjusting rod 4 and the stirring rod 3, and the axis of the hinge is perpendicular to the axis of the rotating drum 2. The adjusting rod 4 is movably arranged along the axis, and the stirring rod 3 is driven to move along the axis through the hinged rod 5.

[0025] like Figure 4 As shown, before impregnation, the adjusting rod 4 is moved to retract the stirring rod 3 toward the center of the drum 2. At this time, the outside of the drum 2 and the inside of the tank body 1 have the largest volume; then, activated carbon and impregnation liquid are added into the tank body 1 until the inside of the tank body 1 is filled with the activated carbon and the impregnation liquid. The specific addition ratio of the activated carbon and the impregnation liquid is set according to the needs of the user. In order to achieve a better impregnation effect, the activated carbon needs to be completely immersed in the impregnation liquid. Then, the activated carbon or the impregnation liquid can be fully mixed by rotating the drum 2. In this process, the preliminary impregnation can be completed, so that the activated carbon can meet the impregnation requirements that can be achieved by traditional impregnation equipment. As shown in FIG. Figure 2 As shown, after that, by moving the adjusting rod 4, the articulated rod 5 is used to drive the stirring rod 3 to move along their respective axes toward the outside of the rotating drum 2, and the stirring rod 3 is used to reduce the space inside the tank body 1, thereby squeezing the mixture of the activated carbon and the impregnation liquid. The purpose is to use pressure to further squeeze the impregnation liquid into the capillary pores of the activated carbon, thereby further improving the impregnation effect of the activated carbon and the loading amount of the active components in the activated carbon.

[0026] Preferably, as Figure 3 shown, the stirring rod 3 is a round rod structure, and a blade 31 is provided at one end of the stirring rod 3 located outside the rotating cylinder 2 to improve the stirring effect.

[0027] Preferably, a pressure sensor is inserted through the tank body 1 to facilitate grasping the internal pressure value of the tank body 1 at any time, so as to accurately control the moving timing and stroke of the adjusting rod 4 conveniently.

[0028] Preferably, as Figure 1 , Figure 2 and Figure 4 shown, the tank body 1 is provided with a top cover 14 to facilitate the installation and maintenance of the mechanisms inside the tank body 1. The feed pipe 12 and the liquid inlet pipe 13 are both arranged on the top cover 14. The connecting pipe 21 passes through the top cover 14, and the top cover 14 is connected to the tank body 1 by screws.

[0029] Preferably, as Figure 1 shown, a driving motor 6 is provided on the top of the top cover 14. A gear is coaxially arranged on its main shaft. A gear ring meshing with the gear is sleeved outside the connecting pipe 21. During operation, the driving motor 6 drives the gear ring to rotate through the gear, so as to drive the connecting pipe 21 and the rotating cylinder 2 to rotate together.

[0030] Preferably, as Figures 1 to 5 shown, an annular groove 41 is coaxially arranged at the upper end of the adjusting rod 4. A ring 7 is arranged in the annular groove 41. The ring 7 is connected to the movable rod of a telescopic device 71. The telescopic device 71 is arranged on the top of the tank body 1. The movable rod of the telescopic device 71 is arranged parallel to the axis of the tank body 1. When the telescopic device 71 is started, the ring 7 can be driven to move along the axis of the tank body 1 through the movable rod. And through the connection mode between the ring 7 and the annular groove 41, the adjusting rod 4 can rotate around the axis following the rotating cylinder 2.

[0031] Further preferably, as Figure 5 shown, a plurality of balls 72 are arranged along the circumference on the top surface and the bottom surface of the ring 7. The balls 72 are respectively in rolling contact with the two side surfaces of the annular groove 41 to reduce the friction force between the ring 7 and the side surface of the annular groove 41.

[0032] The above are only the preferred embodiments of the present invention, and do not represent that they are the only or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all fall within the scope of protection of the present invention.
