Description

Technical Field

[0001] This utility model relates to the technical field of modification treatment equipment, specifically to a modification treatment equipment for activated alumina. Background Technology

[0002] Activated alumina, also known as activated bauxite, is a porous, highly dispersible solid material with a large surface area, good adsorption properties, surface activity, and thermal stability. During the production of activated alumina, modifiers need to be added to improve it. The modification of activated alumina is mainly to further enhance its performance.

[0003] A search revealed a patent, CN219043263U, which discloses a high-temperature modification device for alumina powder. This utility model's high-temperature modification device for alumina powder includes an exhaust pipe. The outer wall of the exhaust pipe is equipped with a cooling mechanism and a heating mechanism. The cooling mechanism includes a first conveying pipe, with a first spiral conveying rod inside the first conveying pipe. A first motor is located on the left side of the first conveying pipe, and the output end of the first motor passes through the left side of the first conveying pipe and connects to the first spiral conveying rod. A discharge pipe is connected to the bottom of the first conveying pipe, and a first flange is located at the bottom of the discharge pipe. Thermal grease is evenly applied between a water pipe and the first conveying pipe. A water pump is connected to the bottom of the water pipe, and a radiator is connected to the left side of the water pump. The radiator is connected to the first conveying pipe. The heating mechanism is located at the top of the first conveying pipe and cooperates with it.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a cooling water pipe installed on the side of the conveying pipe, with the coolant inside the pipe cooling the modified alumina. However, in reality, the temperature of the modified alumina is higher at the beginning of the conveying pipe. While the coolant in the water pipe in the aforementioned comparative document can quickly absorb the heat contained in the alumina, the cooling effect decreases as the temperature of the coolant gradually increases further away from the beginning of the conveying pipe. In some cases, the coolant may even insulate the conveying pipe. Furthermore, a large amount of alumina accumulates in the conveying pipe, and the alumina in the middle of the pipe cools down more slowly, reducing the cooling efficiency of the modified alumina. Therefore, there is an urgent need in the art to improve the modification processing equipment to overcome the shortcomings of the prior art. Utility Model Content

[0031] Please see Figures 1-10A modification treatment device for activated alumina includes a modification tank 1.

The inner wall of the arc-shaped groove 9 is provided with heat exchange tubes 12 that communicate with the condensing device 6. Several first drive motors 14 are fixedly installed on one side of the conveying box 5. The output end of the first drive motor 14 is fixedly installed with a first rotating shaft 15 extending into the cavity 8. A push plate 16 adapted to the arc-shaped groove 9 is fixedly installed on the side of the first rotating shaft 15. A diversion pipe 11 that communicates with each other is fixedly installed between the two ends of the several heat exchange tubes 12. An input pipe 10 and a return pipe are fixedly installed on the side of the two diversion pipes 11 respectively. 13. Both the input pipe 10 and the return pipe 13 are connected to the condensation device 6. A material collection trough 17 connected to the conveying pipe 7 is provided on the side of the cavity 8 near the conveying pipe 7. A modifier storage tank 18 is fixedly installed on the upper part of the modified tank 1. A discharge pipe 19 extending into the modified tank 1 is fixedly installed on the lower part of the modifier storage tank 18. A second control valve 20 for opening and closing the discharge pipe 19 is fixedly installed on the side of the discharge pipe 19. A second drive motor 21 is fixedly installed on the upper part of the modified tank 1. A second rotating shaft 22 connected to the output end of the second drive motor 21 is provided inside the modified tank 1. Several stirring blades 23 are fixedly installed on the side of the second rotating shaft 22. A heating device 24 for heating is fixedly installed inside the side of the modified tank 1. A third drive motor 26 fixedly installed in the conveying box 5 is fixedly installed in the conveying pipe 7. A third rotating shaft 27 extending into the conveying pipe 7 is fixedly installed at the output end of the third drive motor 26. A conveying auger 28 for conveying materials is fixedly installed on the side of the third rotating shaft 27.

[0032] Specifically, when alumina needs to be modified, the alumina is conveyed to the modification tank 1 through the feed pipe 2 by the conveying device, and the second control valve 20 on the side of the discharge pipe 19 is opened to convey the modifier for modifying alumina from the modifier storage tank 18 into the modification tank 1. The second drive motor 21 is turned on, and the output end of the second drive motor 21 drives the second rotating shaft 22 to rotate. The second rotating shaft 22 drives the stirring blade 23 to rotate, and the heating device 24 is turned on to heat the modification tank 1 to modify the alumina. After the alumina modification is completed, the first control valve 4 located on the side of the discharge pipe 3 is opened, and the discharge pipe 3 opens to convey the alumina into the first arc-shaped groove 9 in the conveying box 5. At the same time, several first drive motors 14 are turned on, and the output end of the first drive motor 14 drives the first rotating shaft 15 to rotate. Several push plates 16 are rotated, simultaneously activating several condensing devices 6. The pumps in the condensing devices 6 deliver the cooled liquid to the input pipe 10. The cool liquid flows through the distribution pipe 11 to the heat exchange pipe 12 and then returns to the condensing device 6 through the return pipe 13 for further cooling. The cool liquid in the heat exchange pipe 12 cools the alumina in the arc-shaped groove 9. The alumina in the first arc-shaped groove 9 is pushed to the second arc-shaped groove 9 by the push plates 16. Each arc-shaped groove 9 is cooled individually, improving the efficiency of alumina modification treatment. The alumina in the last arc-shaped groove 9 is pushed by the push plates 16 to the collection trough 17 and falls into the conveying pipe 7. The third drive motor 26 is activated, and the output end of the third drive motor 26 drives the third rotating shaft 27 to rotate. The third rotating shaft 27 drives the conveying auger 28 to rotate, conveying the cooled alumina to the designated position.

The side of the fixing frame 25 abuts against the inner wall of the modified tank 1. When the alumina is mixed and stirred, the fixing frame 25 rotates accordingly. The fixing frame 25 scrapes off the alumina adhering to the inner wall of the modified tank 1 and facilitates the discharge of the modified alumina in the modified tank 1. The stirring blade 23 is fixedly installed between the second rotating shaft 22 and the fixing frame 25, which improves the connection strength of the stirring blade 23.

[0034] As a technical optimization of this utility model, a polygonal plug-in shaft 29 is fixedly installed at the output end of the second drive motor 21, and a plug-in groove 30 adapted to the plug-in shaft 29 is opened at the upper end of the second rotating shaft 22. When it is necessary to clean or maintain the inside of the modified tank 1, the plug-in shaft 29 and the plug-in groove 30 can be disconnected, which facilitates the disconnection of the output end of the second rotating shaft 22 and the second drive motor 21.
