Description

Technical Field

[0001] This application relates to the field of activated carbon acid washing technology, and in particular to an activated carbon acid washing apparatus. Background Technology

[0002] The process of preparing graphite materials from activated carbon includes steps such as activation, acid washing, and passivation. Acid washing is used to remove magnetic substances from the activated carbon. Currently, acid washing of activated carbon often employs a combination of filtration and stirring devices. This involves placing the activated carbon in a filter assembly and reacting it with the acid washing solution, while simultaneously stirring the activated carbon in the filter assembly to ensure complete reaction and accelerate the acid washing process. However, due to the high viscosity of activated carbon powder, stirring can easily prevent the stirring device from rotating continuously, potentially leading to accidents. Furthermore, during the removal of activated carbon from the filter assembly, manual removal is time-consuming and labor-intensive due to the high viscosity of the powder, while automatic discharge may result in activated carbon adhering to the inner wall of the filter assembly, leading to incomplete removal. Therefore, improvements are necessary. Utility Model Content

[0003] To address the shortcomings of the prior art, this application provides an activated carbon acid washing device that can ensure the activated carbon reacts completely with the acid washing solution during the acid washing process while eliminating safety hazards. It can also save time and manpower in the discharge stage while collecting activated carbon powder adhering to the inner wall of the filter component.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] An activated carbon acid washing device includes an acid washing container with an inlet and an outlet fixedly installed on its outer side. A filter barrel is rotatably mounted through the upper part of the acid washing container, and a discharge port is provided at the bottom of the filter barrel extending out of the acid washing container. A matching cover is coaxially movable inside the filter barrel for discharging activated carbon powder remaining on the inner wall of the filter barrel. A stirring rod is rotatably mounted inside the acid washing container and is located on the outer side of the filter barrel.

[0006] The beneficial effects of this utility model are as follows: The activated carbon acid washing device provided in this application achieves activated carbon acid washing through the combined action of the acid washing container and the filter barrel. The movable design of the cover helps to confine the activated carbon powder within the acid washing solution, ensuring complete reaction; it also helps to push the activated carbon adhering to the inner wall of the filter barrel to the discharge port during discharge, achieving more complete discharge. The placement of the stirring rod outside the filter barrel accelerates the reaction rate between the acid washing solution and the activated carbon powder while improving the safety of the device. Attached Figure Description

[0007] The accompanying drawings described herein are merely illustrative of selected embodiments, not all possible implementations, and are not intended to limit the scope of this invention.

[0008] Figure 1 This is a perspective view of the overall structure of an embodiment of this application.

[0009] Figure 2 This is a schematic diagram of the structure of the cover and filter barrel in an embodiment of this application. Detailed Implementation

[0010] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0011] This application provides an activated carbon acid washing device, such as... Figure 1 and Figure 2 As shown, the system includes an acid washing container 1 with an inlet and an outlet fixedly installed on its outer side. A filter barrel 2 is installed through and rotatably in the upper part of the acid washing container 1. The bottom of the filter barrel 2 extends out of the acid washing container 1 and has a discharge port. A matching cover 3 is installed coaxially inside the filter barrel 2. The matching cover 3 is used to discharge the activated carbon powder remaining on the inner wall of the filter barrel 2. A stirring rod 4 is rotatably installed inside the acid washing container 1 and is located on the outer side of the filter barrel 2.

[0012] In application, before acid washing, the acid washing solution is first introduced into the acid washing container 1 through the inlet, and then the activated carbon to be acid washed is added into the filter bucket 2. Then, the matching cover 3 is moved downwards so that it moves into the filter bucket 2. Since the activated carbon powder is generally quite fine, it is easy to float on the top in the acid washing solution. Therefore, the matching cover 3 is moved to the bottom position where it is in contact with the acid washing solution, so as to confine the activated carbon powder inside the acid washing solution, so as to achieve a full reaction and achieve the purpose of acid washing.

[0013] During pickling, filter tank 2 and stirring rod 4 start rotating simultaneously. Because the activated carbon powder is highly viscous, if stirring rod 4 is used directly inside filter tank 2, it may become restricted by the stickiness of the powder and unable to rotate, potentially damaging the apparatus. Therefore, stirring rod 4 is used outside filter tank 2 while the filter tank 2 rotates simultaneously, ensuring a more complete and rapid reaction between the pickling solution and the activated carbon powder. Throughout this process, the cover 3 rotates synchronously with filter tank 2.

[0014] After pickling, first open the outlet of the pickling container 1 to discharge the waste liquid after the reaction is completed. Then open the bottom outlet of the filter bucket 2. Most of the activated carbon powder will flow out through the outlet. A small part will still adhere to the inner wall of the filter bucket 2 due to its high viscosity. Continue to move the matching cover 3 downward. Through the matching cover 3 and the inner wall of the filter bucket 2, this part of the activated carbon powder will be carried to the bottom of the filter bucket 2 for discharge.

[0015] Specifically, the wall of the filter bucket 2 is provided with a filtration zone 21 and a smoothing zone 22 arranged in a circumferential array, with the filtration zone 21 and the smoothing zone 22 spaced apart.

[0016] Specifically, the inner part of the cover 3 is hollow, and its top is connected to a water inlet hose 33. The other end of the water inlet hose 33 is connected to a water pump. The side wall of the cover 3 is provided with cleaning brushes 31 and flow holes 32 arranged in a circumferential array. The cleaning brushes 31 and flow holes 32 are spaced apart. The cleaning brushes 31 are used to cooperate with the filter zone 21 and can sweep out the activated carbon powder attached to the filter zone 21. The flow holes 32 are used to cooperate with the smoothing zone 22 and are connected to the inside of the cover 3. After acid washing, water flows into the inside of the cover 3 through the water inlet hose 33 and then flows out through the flow holes 32, causing the flowing water to carry the activated carbon powder attached to the smoothing zone 22 downward. As the cover 3 moves downward, the cleaning brushes 31 continuously sweep out the activated carbon powder attached to the filter zone 21, causing it to collect at the bottom of the filter tank 2. The water flowing out of the flow holes 32 also continuously carries the activated carbon powder attached to the smoothing zone 22 to collect at the bottom of the filter tank 2, and then discharges through the outlet. The cleaning brush 31 and the flow hole 32 are designed to both remove the activated carbon powder adhering to the inside of the filter cartridge 2 and clean the inside of the filter cartridge 2.

[0017] Specifically, a toothed ring is fitted around the portion of the filter barrel 2 that extends beyond the upper part of the pickling container 1. The top of the stirring rod 4 extends beyond the pickling container 1 and is coaxially connected to a gear. The toothed ring meshes with the gear, and the rotation of the gear is driven by a motor 5. When the motor 5 is started, it drives the gear to rotate, and the stirring rod 4 rotates along with the gear. Under the meshing action of the toothed ring and the gear, the toothed ring drives the filter barrel 2 to rotate simultaneously. The arrangement of the toothed ring and gear facilitates the simultaneous rotation and stopping of the filter barrel 2 and the stirring rod 4. In this embodiment, the small gear drives the large toothed ring, which to some extent limits the position of the stirring rod 4, placing it outside the filter barrel 2 but at a small distance from it. That is, without affecting the operational safety of the device, the stirring effect of the stirring rod 4 is maximized, allowing the activated carbon powder to fully contact the pickling solution and react rapidly.

[0018] Specifically, the pickling container 1 is equipped with a telescopic rod 6 on its outer side. The telescopic rod 6 is placed vertically, and the top of the mating cover 3 is rotatably connected to a support rod 7, so that the support rod 7 is not affected when the mating cover 3 rotates with the filter barrel 2. The support rod 7 includes two vertical rods and one horizontal rod. The two vertical rods are located at both ends of the horizontal rod, which connects the two vertical rods. One of the vertical rods is rotatably connected to the mating cover 3 and its length is greater than the depth of the filter barrel 2. When the mating cover 3 moves to the bottom of the filter barrel 2, one of the vertical rods is still higher than the top of the filter barrel 2 so that the vertical movement of the horizontal rod is not affected. The bottom end of the other vertical rod is connected to the movable end of the telescopic rod 6, so that the telescopic rod 6 controls the vertical movement of the mating cover 3.

[0019] In application, the above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
