[0021] like Figures 1 to 3 As shown, the mixing equipment for ammonium perchlorate reactants in this embodiment includes a mixing vessel 1, which is composed of multiple layers. A lifting mechanism 2 is provided at the upper end of one side of the mixing vessel 1. A lifting frame 3 is provided on one side of the mixing vessel 1 via the lifting mechanism 2. A mounting frame 4 is provided on one side of the lifting frame 3. The mounting frame 4 is located above the mixing vessel 1. A stirring motor 5 is provided at the end of the mounting frame 4 away from the lifting frame 3. The output end of the stirring motor 5 is connected to a lifting rod 6 via a coupling. A lifting hole is provided at the top of the mixing vessel 1. The lifting rod 6 is located inside the mixing vessel 1 through the lifting hole. The diameter of the lifting hole is the same as that of the lifting rod 6. The diameter is set accordingly. The inside of the stirring vessel 1 at the lifting hole is equipped with a sealing seat. When the lifting rod 6 passes through the lifting hole, the adhesive on the surface of the lifting rod 6 is scraped off. The bottom of the lifting rod 6 is equipped with stirring blades 8. The top of the stirring vessel 1 away from the lifting mechanism 2 is equipped with a feed port 10. The bottom of the stirring vessel 1 is equipped with a discharge port 11. The lower end of the discharge port 11 is equipped with a discharge valve to realize the spiral discharge of the discharge port 11. The discharge of the stirring vessel 1 is smooth, fast and thorough, realizing the lifting and stirring of the stirring rod 7 and stirring blades 8, which can promote the up and down tumbling and fusion of the reactants in the stirring vessel 1, so as to make the mixing more thorough.

[0022] Specifically, the lifting mechanism 2 includes a lifting seat 21, a limiting groove 22, a lifting screw 23, a screw sleeve 24, and a servo motor 25. The upper end of the mixing vessel 1 away from the feed inlet 10 is provided with the lifting seat 21. The lifting seat 21 away from the mixing vessel 1 is provided with the limiting groove 22. The lifting screw 23 and the screw sleeve 24 are provided inside the limiting groove 22. The screw sleeve 24 is connected to the lifting screw 23. The lower end of one side of the lifting frame 3 is connected to the screw sleeve 24. The bottom of the lifting screw 23 is connected to the bottom of the lifting seat 21 through a coupling. The output end of the servo motor 25 is connected, and the servo motor 25 is programmed to rotate in both directions. The lifting height is set to correspond to the length of the lifting rod 6. During the stirring process, the servo motor 25 on the lifting seat 21 drives the lifting screw 23 in the limiting groove 22 to rotate. The screw sleeve 24 on the lifting screw 23 drives the lifting frame 3, the mounting frame 4 and the stirring motor 5 to move up and down above the mixing vessel 1. Thus, the lifting rod 6, the stirring rod 7 and the stirring blade 8 are lifted up and down inside the mixing vessel 1 through the lifting mechanism 2.

[0023] Furthermore, there are several stirring blades 8, which are arranged in an irregular polygonal structure and are inclined on the stirring rod 7. When the irregular polygonal structure of the inclined stirring blades 8 is lifted and rotated, it can move the reactants up and down and turn them over.

[0024] Furthermore, a scraper 9 is provided on one side of the stirring rod 7 via a connecting rod. The side of the scraper 9 away from the connecting rod is in contact with the inner wall of the mixing vessel 1. The scraper 9 is lifted and rotated inside the mixing vessel 1 along with the stirring rod 7, which facilitates scraping and stirring the material at the edge of the mixing vessel 1. When discharging, the scraper 9 moves downward from a high position. The scraper 9 rotates and moves downward inside the mixing vessel 1, scraping off the reactants adhering to the inner wall of the mixing vessel 1.

[0025] Furthermore, a spiral rod 71 is provided at the bottom of the stirring rod 7. The spiral rod 71 is moved down and located inside the discharge port 11. During the stirring process of the mixing vessel 1, the bolt rod 71 moves up and down with the stirring rod 7 inside the mixing vessel 1. When the spiral rod 71 is lifted down and moved into the discharge port 11, it will move up and not rotate continuously inside the discharge port 11. When the mixing vessel 1 discharges, the stirring rod 7 is moved down to a low position through the lifting mechanism 2, and the spiral rod 71 at the bottom of the stirring rod 7 moves down to the inside of the discharge port 11. During the discharge process, the spiral rod 71 rotates continuously inside the discharge port 11 to achieve spiral discharge from the discharge port 11.

[0026] Furthermore, the stirred tank 1 includes an outer shell 12, an insulation layer 13, an inner heat-conducting layer 14, a heating jacket 15, and an electric heating wire 16. The outer shell 12 is the outer layer of the stirred tank 1, which is made of stainless steel. The inner heat-conducting layer 14 is the inner layer of the stirred tank 1, which is made of silicon carbide ceramic. The insulation layer 13 is provided on the inner side of the outer shell 12, and it is made of rock wool. A heating jacket 15 is formed between the insulation layer 13 and the inner heat-conducting layer 14. An electric heating wire 16 is provided inside the heating jacket 15. The electric heating wire 16 is spirally wound on the inner heat-conducting layer 14. A temperature sensor is provided at the upper end of the interior of the stirred tank 1. The temperature sensor monitors the reaction mixing temperature inside the stirred tank 1. When the electric heating wire 16 is energized, it heats the reaction mixing inside the stirred tank 1 through the inner heat-conducting layer 14.

[0027] Furthermore, the bottom of the mixing vessel 1 is provided with a support, and the lower end of the mixing vessel 1 is set in a V-shaped structure. The bottom of the mixing blade 8 at the lower end of the mixing rod 7 is set at an inclination. When discharging, when the mixing rod 7 moves down to a low position, the bottom of the mixing blade 8 contacts the bottom of the mixing vessel 1. The mixing blade 8 plays the role of scraping the material at the bottom of the mixing vessel 1. The mixing vessel 1 below the feed inlet 10 is set at an inclination, and the feed slides along the inclination of the mixing vessel 1, making feeding convenient.

[0028] The usage method of this embodiment is as follows: The device is connected to a power source. The raw materials for mixing ammonium perchlorate reactants are fed into the stirred tank 1 through the feed inlet 10. When heating is required for the reaction mixing, the electric heating wire 16 in the heating jacket 15 is energized, heating the stirred tank 1 through the inner heat-conducting layer 14. The stirring mechanism has a heating function. The stirring motor 5 drives the lifting rod 6 and the stirring rod 7 to rotate, causing the stirring blades 8 to rotate inside the stirred tank 1. The stirring blades 8 stir and mix the reactants inside the stirred tank 1. During the stirring process, the servo motor 25 on the lifting seat 21 drives the lifting screw 23 in the limiting groove 22 to rotate. The screw sleeve 24 on the lifting screw 23 drives the lifting frame 3, the mounting frame 4, and the stirring motor 5 to move up and down above the stirred tank 1, thereby driving the lifting rod 6, the stirring rod 7, and the stirring mechanism 2 to move the stirring mechanism 2. The stirring blades 8 move up and down inside the stirred tank 1, rotating and stirring. The irregular polygonal structure of the stirring blades 8 is tilted to promote the tumbling and fusion of reactants inside the stirred tank 1, resulting in more thorough mixing. After mixing, the discharge valve on the discharge port 11 is opened, and the lifting mechanism 2 moves the stirring motor 5, lifting rod 6, stirring rod 7, stirring blades 8, and scraper 9 from a high position downwards. The scraper 9 rotates and moves downwards inside the stirred tank 1, scraping off the reactants adhering to the inner wall of the stirred tank 1. After the lifting mechanism 2 moves to a lower position, it stops lifting. The spiral rod 71 on the stirring rod 7 moves down to the inside of the discharge port 11 and rotates inside the discharge port 11, realizing spiral discharge from the discharge port 11. The discharge from the stirred tank 1 is smooth, fast, and thorough.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
