[0033] Some embodiments of the present application will be described in detail below in combination with the drawings:

[0034] Please refer to Figure 1 - Figure 6, by setting the stirring frame 4 in the heating tank 1, using the heating tank 1 to heat the carbon deposition of the waste catalyst, the pressure in the heating tank 1 is raised, the movable frame 6 is driven in the auxiliary pipe 5, and then the driving assembly 10 drives the rotating shaft 7 and the stirring frame 4 to rotate, and the stirring frame 4 is used to stir the waste catalyst in the heating tank 1.

[0035] Wherein, the driving assembly 10 includes auxiliary shaft 11, auxiliary shaft 11 rotationally arranged in the movable frame 6, the outer side of the auxiliary shaft 11 is fixedly provided with the rolling gear 12 and the first bevel gear 13, the top end of the rotating shaft 7 is fixedly provided with the second bevel gear 14, the second bevel gear 14 is arranged in the movable frame 6, the second bevel gear 14 is meshed and connected with the first bevel gear 13, the limiting rack 15 is fixedly arranged in the auxiliary pipe 5, the movable frame 6 is slidingly connected with the limiting rack 15, the rolling gear 12 is meshed and connected with the limiting rack 15, when the movable frame 6 moves up and down, the rolling gear 12 is rolled on the limiting rack 15, so as to drive the auxiliary shaft 11 to rotate through the rolling gear 12, and the auxiliary shaft 11 drives the rotating shaft 7 to rotate through the rotation of the first bevel gear 13 and the second bevel gear 14.

[0036] It is worth noting that the stirring frame 4 is internally provided with a sliding cavity 25, the top of the sliding cavity 25 is provided with uniformly distributed embedding grooves 16, the bottom outer side of the rotating shaft 7 is fixedly provided with an embedding column 17 which is slidingly matched with the embedding grooves 16, the diameter of the embedding column 17 is smaller than the width of the embedding grooves 16, so as to ensure that the rotating shaft 7 can drive the stirring frame 4 to rotate through the cooperation of the embedding column 17 and the embedding grooves 16 when rotating.

[0037] In addition, the top of the heating tank 1 is fixedly provided with a barometer 26, which is used to monitor the pressure in the heating tank 1 in real time, and when the pressure in the heating tank 1 reaches a critical value, the motor 23 is stopped, the top of the piston plate 9 is fixedly provided with a counterweight ring 24, which is used to increase the overall weight of the structure connected with the rotating shaft 7, so as to ensure that the pressure in the heating tank 1 can smoothly rise to the critical value when the heating starts and the motor 23 drives the stirring frame 4 to rotate.

[0038] The process of waste catalyst heating treatment is described below:

[0039] Firstly, the waste catalyst is placed into the heating tank 1 from the feeding pipe 2, and the feeding pipe 2 and the discharging pipe 3 are sealed by the gate plate 21;

[0040] Then, the motor 23 drives the stirring frame 4 to rotate, at this time, the embedded column 17 is located in the sliding cavity 25, the embedded column 17 rotates with the rotating shaft 7 in the sliding cavity 25 close to the position of the embedded groove 16, and the heating tank 1 is used to heat the waste catalyst, the carbon deposit on the surface of the catalyst becomes carbon dioxide gas when heated, so that the air pressure in the heating tank 1 increases, and the air pressure in the heating tank 1 is recorded in real time by the air pressure gauge 26, when the air pressure in the heating tank 1 reaches a critical value, the air pressure gauge 26 reminds the motor 23 to stop working through an external controller, at this time, with the continuous heating, the air pressure in the heating tank 1 continues to rise, the piston plate 9 is pushed to move upwards in the auxiliary pipe 5, so that the movable frame 6 is driven to move upwards in the auxiliary pipe 5 by the rotating shaft 7, when the movable frame 6 moves upwards, the rolling gear 12 rolls on the limiting rack 15, drives the auxiliary shaft 11 to rotate, the auxiliary shaft 11 drives the rotating shaft 7 to rotate through the meshing of the first bevel gear 13 and the second bevel gear 14, in the process of rotating, the embedded column 17 arranged at the bottom of the rotating shaft 7 slowly revolves with the rotating shaft 7, at this time, with the rising of the rotating shaft 7, the embedded column 17 enters the embedded groove 16, and then with the continuous rotation of the rotating shaft 7, the embedded column 17 is limited in the embedded groove 16, so that the stirring frame 4 is driven to rotate in the heating tank 1 through the embedded groove 16, and the waste catalyst in the heating tank 1 is stirred, at this time, the stirring frame 4 can be driven to rotate without the operation of the motor 23, since the waste catalyst needs a long time to heat and decarburize, this method can effectively reduce the energy consumption caused by the use of the motor 23, and ensure that the waste catalyst is uniformly heated during the decarburization process;

[0041] When the piston plate 9 moves to the connection between the exhaust pipe 8 and the auxiliary pipe 5, the air pressure in the heating tank 1 is released into the exhaust pipe 8, the piston plate 9 drives the movable frame 6 to move downwards under the gravity of the movable frame 6 and the rotating shaft 7, and then drives the rolling gear 12 to turn over on the limiting rack 15, so that the rotating shaft 7 and the stirring frame 4 are reversely rotated through the mutual cooperation of the auxiliary shaft 11, the first bevel gear 13 and the second bevel gear 14, and the catalyst in the heating tank 1 is stirred again;

[0042] With the increase and release of the air pressure in the heating tank 1, the movable frame 6 moves up and down in the auxiliary pipe 5, drives the rotating shaft 7 and the stirring frame 4 to reciprocate in the heating tank 1, and stirs the catalyst in the heating tank 1;

[0043] Finally, the treated catalyst is discharged through the discharge pipe 3.

[0044] In the technical solution, the distance of single upward movement of the movable frame 6 can drive the stirring frame 4 to rotate more than one circle in the heating tank 1, so that the stirring frame 4 can fully stir the catalyst in the heating tank 1 in a single rotation process.

[0045] In the embodiment of the technical solution, as shown in Figure 3 and Figure 6As shown, the auxiliary pipe 5 is internally provided at the top with a compression spring 18, the bottom end of which is fixed to the top of the movable frame 6, and externally provided at the top with a pressure relief hole 19. After the pressure is released from the heating pot 1, the movable frame 6 quickly moves downward under the action of the compression spring 18, thereby ensuring the stable up-and-down movement of the movable frame 6 in the auxiliary pipe 5.
