DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0024] This embodiment provides a concentrated crystallization device for potassium perchlorate production, which is mainly used to solve the problem that the coolant inside the cooling main pipe and the stirring auxiliary pipe has no fluidity, so that the cooling effect of the cooling main pipe and the stirring auxiliary pipe cannot be updated, and provides the following technical solutions. Figure 1-Figure 4 Give detailed instructions:

[0025] A concentration crystallization device for potassium perchlorate production comprises: a stirring chamber 1 with a through hole 2 on the top, a stirring tube 3 rotatably inserted into the through hole 2, a liquid exchange port 4 on the bottom of the stirring chamber 1, and the other end of the stirring tube 3 rotatably inserted into the inner wall of the liquid exchange port 4 and provided with a first electromagnetic valve 5. The user can control the closing state of the first electromagnetic valve 5 through a controller 6 fixedly mounted on the surface of the stirring chamber 1. That is, in actual use, the user adds potassium perchlorate to the inside of the stirring chamber 1, and then introduces a refrigerant into the inside of the stirring tube 3, and then drives the stirring through the driving unit 7. The mixing tube 3 rotates to stir and crystallize potassium perchlorate. During use, the temperature of the refrigerant will continue to rise. The user can open the solenoid valve at the bottom of the mixing tube 3 through the controller 6 to discharge the refrigerant for replacement. The main components of the mixing chamber 1 are: a main chamber body 11 with a conducting pipe 12 at the top and bottom, a through hole 2 is opened at the top of the main chamber body 11, and both conducting pipes 12 are provided with a second solenoid valve 13. The user can control the conduction state of the two second solenoid valves 13 through the controller 6 to achieve the injection and removal of potassium perchlorate inside the main chamber body 11. Discharge, wherein the main components of the stirring tube 3 are: a main body 31 that is rotatably plugged into the inner wall of the through hole 2, and a plurality of stirring edges 32 are provided on the surface of the main body 31. Because one end of the main body 31 is rotatably plugged into the inner wall of the liquid exchange port 4, the user can control the main body 31 to rotate on the inner wall of the liquid exchange port 4 through the drive unit 7 to achieve stirring of potassium perchlorate inside the main chamber 11. In this process, the plurality of stirring edges 32 can improve the stirring effect. The main components of the drive unit 7 are: a mounting bin 71 fixedly mounted on the top of the main chamber 11, During use, the user can introduce refrigerant into the interior of the main body 31 through the liquid injection port 74 on the surface of the installation bin 71. At the same time, the user can control the third solenoid valve 75 of the liquid injection port 74 through the controller 6 to realize control of the conduction state of the liquid injection port 74. When it is necessary to control the rotation of the injection tube body, the output end of the motor 72 fixedly installed on the surface of the installation bin 71 can be controlled by the controller 6 to rotate, and the rotation movement trend of the output end of the motor 72 is transmitted to the main body 31 through the transmission unit 73, so that the main body 31 can be driven synchronously to realize stirring of the material inside the main bin body 11.

[0026] A stirring chamber 1 with a through hole 2 at the top is provided, and a stirring tube 3 is rotatably inserted into the through hole 2. When in use, the user pours potassium perchlorate liquid into the stirring chamber 1 and then introduces low-temperature gas or water into the stirring tube 3. The stirring tube 3 can be controlled to rotate by a driving unit 7, thereby stirring and crystallizing the potassium perchlorate liquid in the stirring chamber 1. During this process, the user can open the first solenoid valve 5 on the surface of the stirring tube 3 through a controller 6 to replace the low-temperature gas or water inside it, thereby ensuring the continuity of its refrigeration.

[0027] By fixing a stirring rack 8 on the surface of the large gear 734, the user can control the output end of the motor 72 to rotate through the controller 6 during use, thereby driving the large gear 734, the small gear 733, and the drive ring 731 to rotate in sequence. Because the rotation directions of the large gear 734 and the drive ring 731 are opposite at this time, the rotation directions of the main body 31 and the stirring rack 8 are also opposite. That is, when the main body 31 stirs the refrigerant inside the main chamber 11, the stirring rack 8 will rotate in the opposite direction inside the main body 31 to stir the refrigerant, thereby effectively improving the fluidity of the refrigerant inside the cooling main body.

[0028] like Figure 4 As shown, in some embodiments, the main components of the transmission unit 73 are: a driving ring 731 fixedly mounted on one end of the main body 31, and the driving ring 731 is rotatably mounted on the inner wall of the through hole 2. When in use, the user controls the output end of the motor 72 to rotate through the controller 6, which can drive the large gear 734 fixedly mounted on the output end of the motor 72 to rotate, and drive the small gear 733 engaged with the large gear 734 to rotate. Because the small gear 733 is rotatably mounted on the surface of the mounting bin 71 and engages with the tooth groove 732 opened on the inner ring of the driving ring 731, the driving ring 731 and the large gear 734 rotate synchronously, but the rotation directions are different. The driving ring 731 further drives the main body 31 to rotate, thereby achieving the purpose of stirring.

[0029] like Figure 2 and Figure 4 As shown, in some embodiments, the main body 31 is a cavity structure and a stirring rack 8 is fixedly installed on the surface of the large gear 734. Because the stirring rack 8 is rotatably inserted into the interior of the cavity structure of the main body 31, the stirring rack 8 will be driven to rotate inside the main body 31 when the large gear 734 rotates, and the rotation direction is opposite to that of the main body 31, thereby achieving stirring of the refrigerant inside the main body 31, allowing it to flow fully and ensuring the continuity of its refrigeration effect. The main components of the stirring chamber 1 are: a sub-tube body 81 with several stirring rings 82 fixedly installed on the surface, and one end of the sub-tube body 81 is fixedly installed on the surface of the large gear 734. Therefore, when the large gear 734 rotates, the sub-tube body 81 will rotate synchronously, and several stirring rings 82 will rotate inside several stirring edges respectively.

[0030] like Figure 1 and Figure 3 As shown, in some embodiments, the controller 6 can receive the internal temperature of the main bin body 11 sensed by the temperature sensor 9 fixedly plugged into the surface of the main bin body 11, thereby controlling the replacement of the refrigerant.

[0031] The workflow of this utility model:

[0032] First, the user introduces the refrigerant through the liquid inlet on the surface of the installation chamber 71 and potassium perchlorate through the conducting pipe 12 at the top of the main chamber body 11. Then, the controller 6 controls the output end of the motor 72 to rotate, which can drive the main body 31 to rotate, thereby achieving stirred crystallization of potassium perchlorate.

[0033] Secondly, after the cooling effect of the refrigerant decreases, the user can control the first solenoid valve 5 through the controller 6 to discharge the refrigerant and add new refrigerant. At the same time, when the main body 31 rotates, the stirring rack 8 inside its cavity will rotate synchronously and in the opposite direction of its rotation. Therefore, the refrigerant inside it will have strong fluidity, ensuring its continuous cooling effect.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
