DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1-Figure 9 As shown, the technical solution adopted by the present invention is as follows: an ammonium perchlorate double decomposition mother liquor evaporation device comprises an evaporation tank 1, a heating component and a container 15 for containing the mother liquor.

[0035] The evaporation tank 1 is provided with a feed pipe 4 through which the mother liquid to be evaporated is injected into the container 15 .

[0036] The container 15 is in a cone shape with the tip facing downward, and the tip of the container 15 is fixedly mounted on the bottom wall of the evaporator 1. In order to ensure the stability of the container 15, a fixing seat 10 is fixedly connected to the outer wall of the container 15, and the fixing seat 10 is fixedly connected to the inner wall of the evaporator 1 through a fixing rod 8.

[0037] The evaporator 1 is rotatably provided with a second telescopic rod 7, the telescopic end of which extends into the container 15, and the second telescopic rod 7 is coaxial with the container 15. The evaporator 1 is provided with a driving assembly for driving the second telescopic rod 7 to rotate.

[0038] The driving assembly includes a motor 20, a first gear 5 and a second gear 6. The motor 20 is embedded and fixedly mounted on the top of the evaporation tank 1, and the first gear 5 is coaxially fixedly mounted on the output shaft of the motor 20. A sleeve 16 is rotatably mounted on the top of the evaporation tank 1, and the second gear 6 is coaxially fixedly sleeved on the sleeve 16, and the second gear 6 is meshed with the first gear 5. The second telescopic rod 7 is coaxially fixedly connected to the sleeve 16.

[0039] The telescopic end of the second telescopic rod 7 is fixedly connected to the first stirring rod 11, and the first stirring rod 11 is adapted to the bottom of the container 15. The two ends of the first stirring rod 11 are hinged to the second stirring rod 13 through the first hinge shaft. The second stirring rod 13 is adapted to the side wall of the container 15. The end of the second stirring rod 13 away from the first stirring rod 11 is connected to the container 15 through a connecting piece.

[0040] The connecting member includes a sliding seat 24 and a limiting sleeve 22. A sliding groove 23 is coaxially provided on the top of the container 15, and a sliding seat 24 is slidably provided in the sliding groove 23. A limiting sleeve 22 is slidably provided at the end of each second stirring rod 13, and the limiting sleeve 22 is hinged to the sliding seat 24 through a second hinge shaft.

[0041] When the first stirring rod 11 is in contact with the bottom wall of the container 15, the second stirring rod 13 is in contact with the side wall of the container 15. The second telescopic rod 7 is shortened, the first stirring rod 11 is moved upward, the lower end of the second stirring rod 13 is moved upward, the second stirring rod 13 gradually changes to a horizontal state, the upper end of the second stirring rod 13 slides outward along the corresponding limit sleeve 22, and the limit sleeve 22 rotates around the second hinge axis. As the second telescopic rod 7 is extended and retracted, the first stirring rod 11 moves up and down, and the second stirring rod 13 moves accordingly, thereby stirring the mother liquid in the container 15 up and down, so that the mother liquid in the container 15 is heated evenly and evaporated faster.

[0042] At the same time, the motor 20 drives the second telescopic rod 7 to rotate through the first gear 5 and the second gear 6, and the first stirring rod 11 and the second stirring rod 13 rotate around the axis of the second telescopic rod 7 to further stir the mother liquid in the container 15 to improve the evaporation efficiency.

[0043] The first stirring rod 11 and the second stirring rod 13 are kept in contact with the container 15, and the second telescopic rod 7 is rotated. The first stirring rod 11 and the second stirring rod 13 are rotated around the second telescopic rod 7, and the first stirring rod 11 and the second stirring rod 13 scrape off the solid matter adhered to the inner wall of the container 15, and the scraped solid matter slides to the bottom of the container 15 under the action of its own gravity.

[0044] The first stirring rod 11 and the second stirring rod 13 are both hollow, and the first stirring rod 11 and the second stirring rod 13 are connected through the elastic tube 12. The first stirring rod 11, the elastic tube 12 and the second stirring rod 13 together constitute a receiving chamber with openings at both ends. The first stirring rod 11 is provided with a plurality of suction ports, each of which is equipped with a one-way valve 17. The solid matter in the container 15 is sucked into the receiving chamber through the suction port.

[0045] Two blocking plates 19 for blocking the second stirring rods 13 are symmetrically arranged on the top of the container 15, and the two blocking plates 19 correspond to the two second stirring rods 13 one by one. An air pump 21 is installed on one of the blocking plates 19. When the blocking plate 19 blocks the second stirring rod 13, the accommodating cavity is closed, the input end of the air pump 21 is connected to the accommodating cavity, and the air pump 21 is started to generate suction force in the accommodating cavity, and the solid matter at the bottom of the container 15 and a small amount of mother liquid are sucked into the accommodating cavity.

[0046] The heating assembly includes a first heating plate 14 and a second heating plate 18, and the first heating plate 14 is embedded in the container 15. The second heating plate 18 is embedded in the first stirring rod 11 and the second stirring rod 13. The first heating plate 14 heats the mother liquid in the container 15, so that the mother liquid evaporates and precipitates solid matter. The second heating plate 18 heats the solid matter entering the receiving chamber, so that the water in the solid matter evaporates and reduces the water in the solid matter in the receiving chamber.

[0047] The evaporator 1 is provided with a material pushing assembly. The material pushing assembly includes a first telescopic rod 3 and a push scraper 9. The first telescopic rod 3 is fixedly mounted on the evaporator 1. The output end of the first telescopic rod 3 is connected to the push scraper 9, and the push scraper 9 is adapted to the receiving chamber. When the solid matter in the receiving chamber needs to be taken out, the first stirring rod 11 is moved upward by the second telescopic rod 7 until the first stirring rod 11 and the second stirring rod 13 are in the same straight line, at which time the end of the second stirring rod 13 away from the first stirring rod 11 extends to the outside of the container 15, and then the solid matter in the receiving chamber is pushed out by the push scraper 9.

[0048] A discharge plate 2 is disposed at the lower part of the evaporation tank 1, and the discharge plate 2 and the push scraper plate 9 are on the same vertical plane. The bottom wall of the evaporation tank 1 is inclined downward toward the side close to the discharge plate 2.

[0049] The first telescopic rod 3 and the second telescopic rod 7 are both electric telescopic rods.

[0050] The outer surfaces of the first stirring rod 11 , the elastic tube 12 and the second stirring rod 13 are all provided with a heat insulation layer.

[0051] Working principle: Initially, the first stirring rod 11 and the second stirring rod 13 are both in contact with the inner wall of the container 15. When in use, the mother liquid to be evaporated is added into the container 15 through the feed pipe 4.

[0052] The second telescopic rod 7 is started to shorten the second telescopic rod 7, and the second telescopic rod 7 drives the first stirring rod 11 to move upward, and the end of the second stirring rod 13 close to the first stirring rod 11 moves upward, and the end of the second stirring rod 13 away from the first stirring rod 11 moves outward along the limiting sleeve 22, and the limiting sleeve 22 rotates around the second hinge axis. The rising height of the first stirring rod 11 is controlled according to the liquid level of the mother liquid in the container 15. When the second telescopic rod 7 is extended, the first stirring rod 11 moves downward, and the end of the second stirring rod 13 close to the first stirring rod 11 moves downward, and the second stirring rod 13 slides along the limiting sleeve 22, and the limiting sleeve 22 rotates around the first hinge axis. Therefore, as the second telescopic rod 7 is extended and retracted, the first stirring rod 11 moves back and forth up and down, and the second stirring rod 13 moves accordingly, and then the mother liquid in the container 15 is stirred up and down, so that the mother liquid is heated evenly and the evaporation is accelerated.

[0053] At the same time, the motor 20 is started, the second telescopic rod 7 rotates, and the first stirring rod 11 and the second stirring rod 13 rotate around the second telescopic rod 7, further stirring the mother liquid in the container 15 in multiple directions to accelerate the evaporation of the mother liquid.

[0054] It should be noted that when the mother liquor is stirred, the rotation direction of the first stirring rod 11 and the second stirring rod 13 can be controlled by controlling the rotation direction of the second telescopic rod 7, so that the second stirring rod 13 avoids the blocking plate 19 to prevent the blocking plate 19 from interfering with the second stirring rod 13.

[0055] As evaporation proceeds, solid matter gradually precipitates, and solid matter adheres to the inner wall of the container 15. When it is necessary to scrape off the solid matter on the inner wall of the container 15, the first stirring rod 11 and the second stirring rod 13 are kept in contact with the inner wall of the container 15, and the second telescopic rod 7 continues to rotate, and the first stirring rod 11 and the second stirring rod 13 rotate around the second telescopic rod 7, and the first stirring rod 11 and the second stirring rod 13 scrape off the solid matter on the inner wall of the container 15, and the scraped solid matter sinks to the bottom of the container 15.

[0056] Afterwards, the second stirring rod 13 is moved to the bottom of the blocking plate 19, the blocking plate 19 blocks the second stirring rod 13, and the motor 20 is turned off. At this time, the accommodating chamber is closed, and then the air pump 21 is started, and the solid material at the bottom of the container 15 is sucked into the accommodating chamber. Of course, a small amount of mother liquid will also enter the accommodating chamber. The second heating plate 18 is started, and the second heating plate 18 heats the solid material in the accommodating chamber to evaporate the water in the solid material quickly, reducing the water in the solid material in the accommodating chamber, and the evaporated water vapor flows out through the end of the second stirring rod 13 away from the first stirring rod 11.

[0057] Turn off the air pump 21, and start the motor 20 and the second telescopic rod 7 again. The first stirring rod 11 and the second stirring rod 13 stir the mother liquid in the container 15 to accelerate the evaporation process. At the same time, when the first stirring rod 11 and the second stirring rod 13 move up and down, the solid material in the receiving chamber is shaken to increase the evaporation rate of the water in the receiving chamber. Since the lower end of the second stirring rod 13 is always in a tilted downward state during the up and down movement of the first stirring rod 11 and the second stirring rod 13, the material in the receiving chamber will not be shaken out.

[0058] When the evaporation in the receiving chamber is completed, one of the second stirring rods 13 is placed in a position corresponding to the push scraper 9. After that, the second telescopic rod 7 is shortened, the first stirring rod 11 is moved upward, and the end of the second stirring rod 13 close to the first stirring rod 11 is moved upward until the second stirring rod 13 is in a horizontal state, at which time the first stirring rod 11 and the second stirring rod 13 are in the same straight line. At this time, the push scraper 9, the first stirring rod 11 and the second stirring rod 13 are in the same straight line. Start the first telescopic rod 3, extend the first telescopic rod 3 into the receiving chamber, and push out the solid matter in the receiving chamber, and the pushed out solid matter falls to the bottom of the evaporator 1.

[0059] A method for using an ammonium perchlorate double decomposition mother liquor evaporation device in the present invention comprises the following steps:

[0060] S1. Add the mother liquid to be evaporated into the container 15 for evaporation.

[0061] S2, starting the second telescopic rod 7 to move the first stirring rod 11 up and down, and at the same time rotating the second telescopic rod 7 to rotate the first stirring rod 11 and the second stirring rod 13 around the container 15, thereby stirring the mother liquid in the container 15.

[0062] S3. Keep the first stirring rod 11 and the second stirring rod 13 in contact with the inner wall of the container 15. The first stirring rod 11 and the second stirring rod 13 rotate around the axis of the container 15. The first stirring rod 11 and the second stirring rod 13 scrape off the solid matter on the inner wall of the container 15, and the scraped solid matter sinks to the bottom of the container 15.

[0063] S4. The end opening of the accommodating cavity is sealed, and the solid matter at the bottom of the container 15 is sucked into the accommodating cavity.

[0064] S5, move the second telescopic rod 7 upward until the second stirring rod 13 is in a horizontal state, and push the solid matter in the accommodating cavity out through the pushing assembly.

[0065] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
