Description

Technical Field

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

[0002] In energy storage materials, 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. Activated carbon is usually prepared by processes such as refinement, pickling, drying, passivation, etc. Currently, commonly used drying equipment needs to centrally input activated carbon into a drying furnace, and the activated carbon contacts with the high-temperature furnace body to achieve the purpose of drying the activated carbon. During the drying process, although the balance of activated carbon drying can be improved by rotating the furnace body, and try to make the activated carbon in the same furnace reach the drying purpose within the same time period. However, since such drying equipment inputs activated carbon in a centralized feeding manner, it still takes a long time to operate to make all the activated carbon evenly heated to achieve the drying purpose, and the drying efficiency is low; if the single input amount is small, although the single drying time can be shortened, the operation frequency of the equipment will be increased, and the feeding and discharging times of the drying equipment will be increased, which will also reduce the drying efficiency. Content of the Utility Model

[0006] The housing is in a cylindrical structure, and a discharge pipe is communicated with the side wall at the upper end of the housing. The discharge pipe is used to connect a bag filter. A plurality of air inlet pipes communicated with the inside of the housing are arranged along the circumference at the bottom of the housing for sending the heated air flow into the housing.

[0007] The inner cylinder is in a cylindrical structure, and it is coaxially arranged inside the housing. There is an annular chamber between the outer wall of the inner cylinder and the inner wall of the housing. The air inlet pipe is communicated with the bottom of the annular chamber, and the air inlet pipe faces upward of the annular chamber; the inner cylinder is rotatably arranged around the axis, its upper end passes through the top of the housing, a feeding port is arranged at the top of the inner cylinder, and discharge holes are formed in the side wall of the inner cylinder.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following describes the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described in the present utility model are some embodiments of the present utility model, not all embodiments.

[0015] As Figures 1 to 3 shown, an activated carbon drying device includes: an outer shell 1 and an inner cylinder 2.

[0016] The outer shell 1 is in a cylindrical structure. A discharge pipe 11 is communicated and provided on the side wall at the upper end of the outer shell 1. The discharge pipe 11 is used to connect to a bag filter. The bag filter is used to collect activated carbon and discharge the air flow. Since the bag filter and the drying device are two independent devices, and the bag filter is a commonly used device for collecting dust and particulate matter, no further description is made here. A plurality of intake pipes 12 communicating with the inside of the outer shell 1 are provided along the circumference at the bottom of the outer shell 1 for sending the heated air flow into the inside of the outer shell 1.

[0017] The inner cylinder 2 is in a cylindrical structure. It is coaxially arranged inside the outer shell 1. There is an annular chamber 201 between the outer wall of the inner cylinder 2 and the inner wall of the outer shell 1. The intake pipe 12 is communicated with the bottom of the annular chamber 201, and the intake pipe 12 faces upward of the annular chamber 201. The inner cylinder 2 is rotatably arranged around the axis. Its upper end passes through the top of the outer shell 1. A feeding port is provided at the top of the inner cylinder 2, and a discharge hole 21 is provided on the side wall of the inner cylinder 2.

[0018] Before drying, the activated carbon to be dried is centrally loaded into the inner cylinder 2 from the feeding port. The activated carbon will be discharged from the discharge holes 21 and enter the annular chamber 201. The heated air flow is introduced into the annular chamber 201 through the air inlet pipe 12, and the activated carbon entering the annular chamber 201 is heated and dried by the air flow. The dried activated carbon will follow the air flow and be discharged from the discharge pipe 11. Finally, the dried activated carbon is collected by a bag filter; during the drying process, the inner cylinder 2 is rotated, which can evenly scatter the activated carbon into the annular chamber 201, improving the drying efficiency of the activated carbon. This structure uses centralized feeding and is discharged dispersedly through the discharge holes 21 to achieve the purpose of continuous feeding, dispersed drying and continuous output. It can not only ensure good drying effect, but also reduce the frequency of centralized feeding and discharging, improving the drying efficiency.

[0019] Preferably, as Figure 1 , Figure 2 shown, the upper end of the outer shell 1 is a conical structure to facilitate the collection of the dried activated carbon and facilitate the discharge of the activated carbon. The discharge pipe 11 is arranged on the side wall of the conical structure.

[0020] Preferably, the air inlet pipe 12 is inclined towards the upper part of the annular chamber 201, and the inclination direction is the same as the rotation direction of the inner cylinder 2. In this way, the air flow can drive the activated carbon to rise in a spiral structure in the annular chamber 201, so as to extend the running track of the air flow and the activated carbon within a limited rising stroke, improving the drying effect of the activated carbon.

[0021] Further preferably, as Figure 1 , Figure 2 shown, the lower ends of all the air inlet pipes 12 are connected to the same annular air pipe 13. In this way, the annular air pipe 13 can be used to stabilize the air flow, and the air flow pressures output by each air inlet pipe 12 are more balanced, which helps to improve the stability of the air flow at various parts inside the annular chamber 201. The annular air pipe 13 is connected to the air intake device through one or more ports.

[0022] Preferably, as Figure 1 , Figure 2 shown, the feeding port of the inner cylinder 2 is provided with a detachable cover plate 22 to prevent the air flow and the activated carbon from overflowing.

[0023] Preferably, as Figure 2 shown, the inner bottom surface of the inner cylinder 2 is provided with a frustum of a cone 23 to prevent the activated carbon from accumulating at the bottom of the inner cylinder 2. The lower edge of the side surface of the frustum of a cone 23 is within the range of the lowermost discharge holes 21, so as to facilitate the complete discharge of the activated carbon inside the inner cylinder 2.

[0024] Preferably, as Figure 2 , Figure 3As shown in the figure, the discharge hole 21 is arranged at the lower section of the inner cylinder 2 to prevent the activated carbon discharged from the discharge hole 21 from quickly entering the discharge pipe 11 when the discharge hole 21 is arranged at the upper section of the inner cylinder 2, thereby reducing the drying effect of the activated carbon.

[0025] Preferably, as Figure 3 shown in the figure, a plurality of flow guide plates 24 are arranged along the circumference of the outer wall of the inner cylinder 2, and their upper ends are inclined towards the rotation direction of the inner cylinder 2, so as to guide the airflow to drive the activated carbon to rotate and rise when the inner cylinder 2 rotates, making the rising trajectory of the airflow more stable and constant; as a further preference, the discharge hole 21 is arranged at the lower section of the inner cylinder 2, and the flow guide plates 24 are arranged at the upper section of the inner cylinder 2.

[0026] Preferably, the discharge pipe 11 is connected with an exhaust pump or similar negative pressure equipment to improve the fluidity of the airflow. Specifically, the exhaust pump can be arranged between the bag filter and the discharge pipe 11 or behind the bag filter.

[0027] Preferably, as Figure 1 、 Figure 2 shown in the figure, a driving motor is arranged at the bottom of the outer shell 1, and a connecting shaft is arranged at the lower end of the inner cylinder 2. The connecting shaft is connected to the main shaft of the driving motor through a gear transmission structure.

[0028] The above are only the preferred embodiments of the present invention and do not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from the scope of the present invention all belong to the scope of protection of the present invention.
