Abstract
Description
Technical Field
[0001] This utility model relates to the field of activated carbon regeneration technology, and in particular to a regenerated activated carbon drying device. Background Technology
[0002] In the current era of rapid development in the environmental protection industry, activated carbon, due to its powerful adsorption properties, is widely used in industrial wastewater treatment, exhaust gas purification, and food and beverage purification. After becoming saturated, activated carbon can be reused through regeneration, thereby reducing usage costs and aligning with the development needs of a green circular economy. Drying, as a crucial step in the activated carbon regeneration process, directly impacts the quality of regenerated activated carbon and its subsequent performance.
[0003] However, existing technologies for drying regenerated activated carbon suffer from uneven drying and low efficiency. For example, some drum-type drying equipment has a large processing capacity, but the activated carbon in the drum only relies on rotation and spillage to come into contact with the hot airflow, which can easily lead to local over-drying and local under-drying. On the other hand, some traditional chamber-type drying equipment has activated carbon in a static state, resulting in low heat exchange efficiency and excessive drying time, which leads to increased energy consumption and production costs. Utility Model Content
[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a regenerated activated carbon drying device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a regenerated activated carbon drying device, comprising a support platform, a support frame and a drying box, wherein a mixing mechanism is provided inside the drying box, a drying mechanism is provided at one end of the drying box, and a waste gas treatment device is provided at the upper end of the support platform.
[0006] The mixing mechanism includes a power system. A stirring shaft is rotatably installed inside the drying chamber. Multiple sets of semi-circular convex plates are fixedly installed on the outer wall of the stirring shaft. Multiple sets of ventilation holes are opened through one end of each set of semi-circular convex plates.
[0007] The drying mechanism includes a slanted support base, a hot air blower is fixedly installed at the upper end of the slanted support base, a connecting pipe is installed through one end of the drying box, a vertical pipe is installed through the upper end of the connecting pipe, and a heating component is fixedly installed at the upper end of the slanted support base.

[0011] Preferably, the exhaust gas treatment device includes a support frame, a shaped tube is installed through the upper end of the sealing cover, and a filter assembly is fixedly installed at the upper end of the support frame.
[0012] Preferably, the lower end of the bracket is fixed to the upper end of the support platform, and the other end of the irregular tube is fixed to the upper opening of the filter assembly.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by setting up a mixing mechanism, the design of the semi-circular convex plate and the ventilation hole enables the stirring shaft to tumble and stir the regenerated activated carbon in all directions and at multiple angles when it rotates, which greatly increases the contact area and contact time between the activated carbon and the hot air flow. Compared with traditional drying equipment, the activated carbon can be heated quickly and evenly in the drying box, effectively avoiding the problem of local over-drying or under-drying, improving drying efficiency, and the moisture content of the dried activated carbon fluctuates within a smaller range, significantly improving quality stability.
[0015] 2. In this utility model, the combination of hot air blower and heating component in the drying mechanism can flexibly adjust the temperature and flow rate of hot air according to the characteristics and drying requirements of the regenerated activated carbon. Whether it is activated carbon with high moisture content or special activated carbon that is sensitive to temperature, precise drying can be achieved by adjusting the equipment parameters, thus broadening the application range of the equipment and meeting diverse production needs.
[0016] 2. In this utility model, the waste gas treatment device effectively treats the waste gas generated during the drying process, which not only avoids environmental pollution, but also, through reasonable design, recovers and utilizes some of the residual heat in the waste gas, further improving energy utilization and reducing enterprise production costs.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a regenerated activated carbon drying device, including a support platform 1, a support frame 11 and a drying box 12. The drying box 12 is equipped with a mixing mechanism 2 inside, a drying mechanism 3 is provided at one end of the drying box 12, and a waste gas treatment device 4 is provided at the upper end of the support platform 1.
[0025] The mixing mechanism 2 includes a power system 21. A stirring shaft 22 is rotatably installed inside the drying box 12. Multiple sets of semi-circular convex plates 23 are fixedly installed on the outer wall of the stirring shaft 22. Multiple sets of ventilation holes 24 are opened through one end of each set of semi-circular convex plates 23. The lower end of the power system 21 is fixed to the upper end of the support frame 11. One end of the stirring shaft 22 is fixed to the output end of the power system 21.
[0026] The drying mechanism 3 includes a diagonal support 31, a hot air blower 32 is fixedly installed on the upper end of the diagonal support 31, a connecting pipe 33 is installed through one end of the drying box 12, a vertical pipe 34 is installed through the upper end of the connecting pipe 33, a heating component 35 is fixedly installed on the upper end of the diagonal support 31, the other end of the connecting pipe 33 is fixed to the air outlet of the hot air blower 32, and the upper end of the vertical pipe 34 is fixed to the opening of the heating component 35.
[0027] A sealing cover 13 is hinged to the upper end of the support platform 1, the lower end of the support frame 11 is fixed to the upper end of the support platform 1, and the lower end of the drying oven 12 is fixed to the upper end of the support frame 11.
[0028] The specific settings and functions of this embodiment are described below. The lower end of the support frame 11 is stably installed on the upper end of the support platform 1, providing basic support for the entire equipment. The lower end of the drying chamber 12 is fixedly connected to the upper end of the support frame 11, forming the core space for drying. The upper end of the support platform 1 is hinged with a sealing cover 13, which can be opened and closed flexibly to facilitate the loading and unloading of regenerated activated carbon. At the same time, it can effectively seal the drying chamber 12 during the drying process to prevent heat loss and exhaust gas leakage. The lower end of the drying chamber 12 is equipped with a discharge mechanism to facilitate unloading of the drying chamber 12.
[0029] The lower end of the power system 21 is fixedly connected to the upper end of the support frame 11, providing a power source for the mixing process. Inside the drying chamber 12, a stirring shaft 22 is rotatably mounted. One end of the stirring shaft 22 is fixedly connected to the output end of the power system 21. Driven by the power system 21, the stirring shaft 22 can rotate stably inside the drying chamber 12. Multiple sets of semi-circular convex plates 23 are fixedly mounted on the outer wall of the stirring shaft 22. These semi-circular convex plates 23 are evenly distributed at a specific interval, and multiple sets of ventilation holes 24 are opened through one end of the semi-circular convex plates 23. When the stirring shaft 22 rotates, the semi-circular convex plates 23 can fully agitate the regenerated activated carbon, so that the activated carbon forms a circulating motion inside the drying chamber 12, increasing the contact opportunity between the activated carbon and the hot airflow. The ventilation holes 24 allow the hot airflow to pass directly through the semi-circular convex plates 23, further improving the heat exchange efficiency and ensuring uniform drying of the activated carbon.
[0030] The inclined support 31 provides stable support, and a hot air blower 32 is fixedly installed on its upper end. A connecting pipe 33 is installed through one end of the drying chamber 12, and the other end of the connecting pipe 33 is fixedly connected to the air outlet of the hot air blower 32. The airflow generated by the hot air blower 32 can be transported to the drying chamber 12 through the connecting pipe 33. A vertical pipe 34 is installed through the upper end of the connecting pipe 33, and the upper end of the vertical pipe 34 is fixedly connected to the opening of the heating component 35. The heating component 35 heats the airflow, turning the room temperature airflow into a high temperature hot airflow. The heated hot airflow enters the drying chamber 12 through the vertical pipe 34 and the connecting pipe 33, providing the required heat for the drying of regenerated activated carbon. The hot air blower 32 and the heating component 35 work together to precisely control the flow rate and temperature of the hot airflow, meeting the drying needs under different working conditions.
[0031] Example 2: Figure 1 and Figure 2As shown, the exhaust gas treatment device 4 includes a bracket 41, a shaped tube 42 is installed through the upper end of the sealing cover 13, a filter assembly 43 is fixedly installed on the upper end of the bracket 41, the lower end of the bracket 41 is fixed to the upper end of the support platform 1, and the other end of the shaped tube 42 is fixed to the upper opening of the filter assembly 43.
[0032] The overall effect of this embodiment is that the lower end of the bracket 41 is fixedly installed on the upper end of the support platform 1, which serves as a support and fixation function; the upper end of the sealing cover 13 is through which a special-shaped tube 42 is installed, and the exhaust gas generated in the drying box 12 is discharged through the special-shaped tube 42; the other end of the special-shaped tube 42 is fixedly connected to the upper opening of the filter assembly 43, and the filter assembly 43 is provided with a multi-layer filter structure, which can efficiently filter pollutants such as dust and volatile organic compounds in the exhaust gas, ensuring that the discharged gas meets environmental protection standards and avoids pollution to the environment.
[0033] The method of use and working principle of this device: Open the top opening of the sealing cover 13 hinged to the upper end of the support platform 1, pour the regenerated activated carbon that needs to be dried into the drying box 12, and after loading, close the opening of the sealing cover 13 to ensure that the drying box 12 is in a sealed state.
[0034] Then, the power system 21, hot air blower 32 and heating component 35 are started. The power system 21 outputs power to drive the stirring shaft 22 to rotate inside the drying chamber 12. Multiple sets of semi-circular convex plates 23 fixed on the outer wall of the stirring shaft 22 rotate accordingly. The semi-circular convex plates 23 are distributed in a specific spiral shape. During the rotation, they can continuously pick up, throw and turn the activated carbon, so that the activated carbon forms a circulation motion inside the drying chamber 12. At the same time, multiple sets of ventilation holes 24 opened on the semi-circular convex plates 23 provide a channel for the hot air to pass through the semi-circular convex plates 23, so that the hot air can directly contact the activated carbon turned by the semi-circular convex plates 23, and perform preliminary mixing and preheating of the activated carbon in advance.
[0035] The hot air blower 32 generates airflow, which enters the vertical pipe 34 through the connecting pipe 33 and then enters the heating component 35. In the heating component 35, the airflow is heated to the set temperature and transformed into a high-temperature hot airflow. The high-temperature hot airflow is transported to the drying chamber 12 through the vertical pipe 34 and the connecting pipe 33. In the drying chamber 12, the hot airflow comes into full contact with the regenerated activated carbon that has been fully turned over by the mixing mechanism 2. Through heat conduction, convection and other means, heat is transferred to the activated carbon, causing the moisture in the activated carbon to evaporate and vaporize rapidly.
[0036] Finally, during the drying process, the moisture evaporated from the activated carbon and the small amount of residual volatile organic compounds form waste gas. This waste gas is discharged from the drying chamber 12 through the irregular tube 42 on the sealing cover 13, and then enters the filter assembly 43. The filter assembly 43 is equipped with a multi-layer filter structure. First, the dust particles in the waste gas are removed through physical interception, so that the waste gas is purified.
[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
