The properties of activated alumina are mainly: large specific surface area, strong reaction activity, good adsorption performance, and excellent thermal stability. Activated alumina is the raw material for the preparation of cutting-edge materials such as aerospace, weapons, electronics and special ceramics. It is an excellent automobile exhaust purifier and is used as a catalyst or carrier in the petrochemical and chemical industries. It is widely used as an adsorbent and dehydrating agent in various industries.

[0003] Chinese patent number: CN103332717A, proposes a method for producing high-activity alumina, the method comprising the following steps: preparing an aluminum sulfate solution with a concentration of 0.1 mol / L to 2.0 mol / L; preparing an ammonium carbonate solution with a concentration of 0.2 mol / L to 3.5 mol / L; adding the aluminum sulfate solution to the ammonium carbonate solution under stirring to react; after the reaction is completed, stopping stirring, filtering and washing to obtain ammonium aluminum carbonate; after drying and roasting the ammonium aluminum carbonate, high-activity alumina can be obtained. During the roasting process of ammonium aluminum carbonate, the main components of the flue gas produced by decomposition are carbon dioxide and ammonia, which can be recycled for the preparation of ammonium carbonate solution. The process flow of the present invention for preparing high-activity alumina is simple, easy to operate, easy to mass produce, and has low production cost.

[0028] See also Figure 1-7 The utility model provides a technical solution: a high-activity alumina powder preparation device, comprising a base 1, a support plate 2 is installed on the top of the base 1, a top plate 3 is installed on the top of the support plate 2, a heating box 4 is installed on the top of the top plate 3, and a reaction kettle 5 is rotatably installed inside the heating box 4; the reaction kettle 5 is used to stir and react the raw materials for preparing the high-activity alumina powder. After hot water is injected into the heating box 4, water bath heating is realized, and the reaction kettle 5 can be heated and temperature-controlled by heat conduction, thereby achieving the purpose of adjusting the temperature of the temperature reaction.

[0029] Furthermore, a heating component for water-bathing the reaction kettle 5 is installed on the top of the base 1; the heating component includes a water tank 6, which is installed on one side of the top of the base 1, and an electric heater 7 is installed on one side of the water tank 6, and the heating end of the electric heater 7 extends to the inside of the water tank 6.

[0030] Specifically, a water supply assembly for conveying the water in the heating assembly to the heating box 4 is installed on the other side of the top of the base 1, and the heating assembly is connected to the interior of the heating box 4 through the water supply assembly; the water supply assembly includes a pump 8, the pumping end of the pump 8 is connected to the interior of the water tank 6, and the drainage end of the pump 8 is connected to the first pipe 9, and the end of the first pipe 9 away from the pump 8 passes through the top plate 3 and is connected to one side of the water tank 6.

By starting the pump 8, the pump 8 extracts the hot water in the water tank 6 into the first pipe 9 and the heating box 4, and the heat of the hot water is absorbed by the reactor 5. At the same time, after the hot water is injected to a certain amount, by opening the valve on the second pipe 10, the hot water in the heating box 4 enters the water tank 6 through the second pipe 10, and the water that loses the temperature can be heated again by the electric heater 7 to achieve the circulation heating of the water.

[0031] Furthermore, a driving assembly for controlling the swing of the reactor 5 to promote the solution reaction is installed on one side of the top of the top plate 3, and one end of the driving assembly is connected to the reactor 5.

[0034] Furthermore, by starting the motor 20, the output shaft of the motor 20 drives the bidirectional screw 18 to rotate, and the bidirectional screw 18 drives the screw sleeve 21 to reciprocate while rotating. While the screw sleeve 21 reciprocates, the connecting rod 23 and the vertical rod 24 are driven to swing back and forth through the guide rod 22. While the vertical rod 24 swings, it drives the second rotating shaft 12 to rotate. While the second rotating shaft 12 rotates, it drives the reactor 5 to swing. While the reactor 5 swings, the solution in the reactor 5 can be mixed. At the same time, while the reactor 5 swings, it can push the water in the heating box 4, promote the flow of water, improve the uniformity of water temperature, and thereby improve the effect of the reaction.
