Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a high-efficiency mixing equipment for CO-assisted olefin catalysts. Background Technology

[0002] The main function of CO-promoted olefin catalysts is to promote the conversion of CO to CO2 in the regenerator and reduce the poisoning of catalysts by metallic nickel and vanadium, thereby improving the activity and selectivity of cracking agents. Mixing equipment is required to mix the catalysts during production.

[0003] A search revealed a patent, CN219051071U, which discloses a catalyst mixing tank. The tank includes a base plate, a vertical plate fixedly mounted on the end of the base plate, a support plate on the vertical plate, and a mixing device on the support plate. The mixing device includes a drive motor fixedly mounted on the support plate, a mixing cylinder fixedly mounted at the end of the drive motor's output shaft, a feed pipe fixedly mounted at the top of the mixing cylinder, and a sealing cap hinged to the top surface of the feed pipe. Bolt plates are fixedly mounted on both the feed pipe and the sealing cap, and the two bolt plates are connected by fastening bolts. A discharge hopper is fixedly mounted on the front side of the support plate. A rectangular groove with its top communicating with the outside is provided inside the vertical plate, and the support plate is located within and slidably connected to the rectangular groove. A lifting device is provided on the vertical plate. This invention facilitates thorough catalyst mixing, convenient discharge, and provides convenience for users.

[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 method of mixing the catalyst inside a mixing cylinder by driving a motor to rotate. However, in reality, when the mixing cylinder is rotated by the motor described in the comparative document, the catalyst slides along its inner wall inside the mixing cylinder. To achieve complete mixing of the catalyst, the mixing cylinder needs to be rotated for a long time, which reduces the efficiency of catalyst mixing. Therefore, there is an urgent need in the art to improve the mixing equipment in order to overcome the shortcomings of the prior art. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 A high-efficiency mixing device for CO-assisted olefin catalyst includes a support frame 1, a mixing tank 2 on one side of the upper part of the support frame 1, a first drive motor 3 fixedly installed on the upper part of the support frame 1 for driving the mixing tank 2 to move up and down, a second drive motor 4 on one side of the support frame 1 for driving the mixing tank 2 to rotate, an air suction pump 5 for air suction on one side of the support frame 1, a vertical conveying pipe 6 adapted to the mixing tank 2 fixedly installed on the upper part of the air suction pump 5, an air blowing head 7 extending into the mixing tank 2 fixedly installed on the side of the mixing tank 2, a flexible air supply pipe 8 with elasticity fixedly installed between several air blowing heads 7 and the conveying pipe 6, a third drive motor 9 and an inlet / outlet pipe 10 fixedly installed at both ends of the mixing tank 2, the third drive motor 9 for stirring the material in the mixing tank 2, and an electromagnetic valve for controlling the opening and closing of the inlet / outlet pipe 10 fixedly installed on the side.

[0029] Specifically, when the CO olefin catalyst needs to be mixed, the second drive motor 4 rotates the mixing tank 2, rotating the inlet / outlet pipe 10 to the upper position, opening the solenoid valve on the side of the inlet / outlet pipe 10, and putting the catalyst to be mixed into the mixing tank 2. Then, the solenoid valve is closed, and the second drive motor 4 is turned on to slowly rotate the mixing tank 2 back and forth. At the same time, the suction pump 5 is started, and the suction pump 5 delivers gas to the delivery pipe 6, and then delivers it to the blowing head 7 through the flexible gas delivery pipe 8. The flexible gas delivery pipe 8 is elastic and does not hinder the reciprocating rotation of the mixing tank 2. The blowing head 7 is also equipped with a solenoid valve. The blowing head 7 blows high-pressure gas into the mixing tank 2, which blows the catalyst in the mixing tank 2 to achieve efficient mixing of the catalyst. After the catalyst is mixed, the second drive motor 4 rotates the inlet / outlet pipe 10 of the mixing tank 2 to the lower position, and the solenoid valve is opened to discharge the mixed catalyst.

[0030] As a technical optimization of this utility model, a sliding block 11 is slidably connected to the side of the support frame 1, and a sliding groove 12 adapted to the sliding block 11 is passed through the side of the support frame 1. A drive screw 13 with one end fixedly installed to the output end of the first drive motor 3 is rotatably connected in the sliding groove 12. The drive screw 13 passes through the sliding block 11 and is threadedly connected to it. A mounting base 14 is fixedly installed on one side of the mixing tank 2. The second drive motor 4 is fixedly installed on one side of the sliding block 11, and its output end passes through the sliding block 11 and is fixedly installed to the mounting base 14. A discharge hopper 18 is fixedly installed on the lower side of the support frame 1. The discharge hopper 18 is located below the mixing tank 2 and is adapted to the inlet and outlet pipes 10. A fixing frame 19 is fixedly installed on the upper part of the support frame 1. A feeding hopper 20 is fixedly installed on one side of the fixing frame 19. The lower part of the feeding hopper 20 is adapted to the inlet and outlet pipes 10.

[0031] Specifically, the first drive motor 3 is turned on, and the output end of the first drive motor 3 drives the drive screw 13 to rotate. When the drive screw 13 rotates, it drives the sliding block 11 to move in the sliding groove 12. The sliding block 11 drives the mixing tank 2 to move up and down. The output end of the second drive motor 4 drives the mounting base 14 to rotate. The mounting base 14 drives the mixing tank 2 to rotate. When the mixing tank 2 is rotated, the first drive motor 3 drives the mixing tank 2 to the position between the discharge hopper 18 and the feeding hopper 20. When it is necessary to add catalyst, the upper end of the inlet / outlet pipe 10 is rotated to the top, and the first drive motor 3 drives the mixing tank 2 to move upward. The inlet / outlet pipe 10 is pressed tightly against the lower end of the feeding hopper 20 to facilitate the addition of catalyst. After the catalyst is mixed, the inlet / outlet pipe 10 is rotated to the bottom, and the first drive motor 3 drives the mixing tank 2 to move downward. The inlet / outlet pipe 10 is opened to facilitate the discharge of catalyst, further improving the mixing efficiency of the catalyst.

[0032] As a technical optimization of this utility model, the output end of the third drive motor 9 is fixedly installed with a rotating shaft 15 extending into the mixing tank 2. Several mixing plates 16 are fixedly installed on the inner side of the rotating shaft 15 in the mixing tank 2. Several connecting frames 17 are fixedly installed between the upper and lower sides of the rotating shaft 15 in the mixing tank 2. Several mixing plates 16 are fixedly installed between the rotating shaft 15 and the connecting frames 17. The upper and lower side walls of the mixing tank 2 are inclined. The side of the connecting frame 17 abuts against the inner side wall of the mixing tank 2.

[0033] Specifically, when mixing the catalyst in the mixing tank 2, the third drive motor 9 is started simultaneously. The output end of the third drive motor 9 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the mixing plate 16 to rotate, stirring and mixing the catalyst to improve the mixing efficiency of the catalyst. At the same time, the mixing plate 16 is fixedly installed between the rotating shaft 15 and the connecting frame 17 to improve the connection strength of the mixing plate 16. The side of the connecting frame 17 abuts against the inner wall of the mixing tank 2 to prevent the catalyst from sticking to the inner wall of the mixing tank 2. The connecting frame 17 can rotate to cooperate with the inner wall of the mixing tank 2 in an inclined shape, which facilitates the complete discharge of the catalyst inside the mixing tank 2.
