[0002] Ammonium perchlorate is an inorganic compound, a white crystalline powder, and is deliquescent. Ammonium perchlorate is a strong oxidant, and will explode when mixed with reducing agents, organic matter, flammable substances such as sulfur, phosphorus, or metal powder.

[0042] A vertical slot 30 is formed on the vertical portion of the limit block 14 , and a protrusion is fixed on the magnetic strip 25 , and the protrusion is slidably engaged in the vertical slot 30 .

[0043] An arc groove 41 is provided at the position where the vertical part and the straight part of the limit block 14 are connected. Two symmetrically arranged support plates 40 are fixed on the free end of the straight part of the limit block 14, and one end of the support plate 40 facing the center of the inner liner 15 is inclined upward, and a straight groove 35 is provided on the support plate 40, and the length direction of the straight groove 35 is parallel to the length direction of the support plate 40.

[0044] The lower end of the magnetic strip 25 is rotatably connected with a magnetic chain. The magnetic chain includes a plurality of first magnetic blocks 23, the ends of two adjacent first magnetic blocks 23 facing away from the inner wall of the liner 15 are rotatably connected by a pin, and the first magnetic block 23 adjacent to the magnetic strip 25 is rotatably connected to the lower end of the magnetic strip 25 by a pin. The lower end of the magnetic chain is connected with a second magnetic block 39, and the second magnetic block 39 is rotatably connected to the first magnetic block 23 adjacent to the magnetic strip 25 by a pin, and the pin of the magnetic chain part away from the magnetic strip 25 is slidably engaged in the guide groove.

[0045] A plurality of magnetic plates 37 are evenly distributed and fixed on the circumference of the lower end of the lowest stirring seat 24. The magnetic pole at the upper end of the second magnetic block 39 is the same as the magnetic pole at the lower end of the magnetic plate 37. The magnetic pole at the upper end of the first magnetic block 23 entering between the two support plates 40 is the same as the magnetic pole at the lower end of the magnetic plate 37.

[0046] The upper control valve 10 is opened, and the ammonium perchlorate liquid material is added into the inner pot 15 through the inlet pipe 8. The motor 7 and the heating plate 13 are started, and the heating plate 13 heats the ammonium perchlorate liquid material in the inner pot 15, and the steam is discharged through the air pipe 38. The motor 7 drives the inner pot 15 to rotate through the first pulley 3, the second pulley 5, the belt 4, the gear 17 and the gear ring 16. At the same time, the output shaft of the motor 7 drives the stirring assembly to rotate as a whole, and the inner pot 15 rotates in the opposite direction to the stirring assembly.

[0047] During the rotation of the inner liner 15 , the swivel 20 , the magnetic strip 25 , the limit block 14 and the guide rod 28 rotate accordingly, so the stirring efficiency of the ammonium perchlorate liquid material can be improved during the rotation of the inner liner 15 .

[0048] During the rotation of the stirring assembly, the stirring seat 24 drives the multiple third magnetic blocks 32 thereon to rotate. When the third magnetic block 32 corresponds to the magnetic strip 25, since the magnetic pole of the end of the magnetic strip 25 facing the center of the inner liner 15 is the same as the magnetic pole of the end of the third magnetic block 32 away from the center of the inner liner 15, the third magnetic block 32 can overcome the centrifugal force and approach the center of the inner liner 15 along the radial direction of the inner liner 15.

[0049] When the third magnetic block 32 is misaligned with the magnetic strip 25 , under the action of centrifugal force, the third magnetic block 32 moves away from the center of the inner liner 15 along the radial direction of the inner liner 15 .

[0050] During the rotation of the stirring seat 24, the third magnetic block 32 can reciprocate along the radial direction of the inner container 15, which can improve the stirring efficiency of the ammonium perchlorate liquid material and further improve the concentration efficiency.

[0051] In the later stage of the ammonium perchlorate liquid material concentration process, the liquid level of the ammonium perchlorate liquid material in the inner liner 15 decreases, and ammonium perchlorate crystals are precipitated in the lower end of the inner liner 15. During the rotation of the inner liner 15, the support plate 40 can stir the lower part of the ammonium perchlorate liquid material, thereby ensuring the concentration rate.

[0052] In order to further improve the stirring efficiency, the electric push rod 9 is started, and the rotating ring 20 drives the magnetic strip 25 downward. When the magnetic strip 25 moves downward, the upper block at the upper end of the magnetic strip 25 moves in the second slide groove 27 under the guiding action of the third slide groove 29 on the guide rod 28 through the guide block, and the magnetic strip 25 approaches the center of the inner container 15. Since the protrusion on the magnetic strip 25 slides in the vertical groove 30 when the magnetic strip 25 moves downward, when the magnetic strip 25 approaches the center of the inner container 15, the limit block 14 also approaches the center of the inner container 15, and the guide column 26 moves relative to the inner container 15.

[0053] As the magnetic strip 25 moves downward and approaches the center of the inner container 15, under the guiding effect of the arc groove 41 on the first magnetic block 23 and the guiding effect of the guide groove on the pin shaft, the number of the first magnetic blocks 23 entering between the two support plates 40 connected to the limit block 14 gradually increases, and the second magnetic block 39 and the first magnetic block 23 between the two support plates 40 gradually move toward the bottom of the stirring assembly.

[0054] During the rotation of the inner tank 15 and the stirring assembly, after the second magnetic block 39 and the first magnetic block 23 correspond to the magnetic plate 37 up and down, since the magnetic pole at the upper end of the second magnetic block 39 is the same as the magnetic pole at the lower end of the magnetic plate 37, the magnetic pole at the upper end of the first magnetic block 23 entering between the two support plates 40 is the same as the magnetic pole at the lower end of the magnetic plate 37. Therefore, after the second magnetic block 39 and the first magnetic block 23 correspond to the magnetic plate 37 up and down, the multiple stirring seats 24 on the spline shaft 34 can move upward and compress the spring 33. When the second magnetic block 39 and the first magnetic block 23 are misaligned with the magnetic plate 37, the stirring seat 24 is restored downward, that is, the stirring seat 24 can move up and down intermittently during the rotation, which can further improve the stirring efficiency of the ammonium perchlorate material.

[0055] After the ammonium perchlorate liquid material is concentrated, the lower control valve 22 is opened, and the concentrated ammonium perchlorate liquid material is discharged through the outlet pipe 21.

[0056] A method for concentrating ammonium perchlorate liquid material by an ammonium perchlorate concentration system comprises the following steps:

[0057] S1, close the outlet pipe 21, open the inlet pipe 8, and add the ammonium perchlorate liquid material into the inner container 15 through the inlet pipe 8.

[0058] S2, start the heating plate 13 to heat the ammonium perchlorate liquid material in the inner container 15, and at the same time, drive the stirring component and the inner container 15 to rotate.

[0059] S3. After the ammonium perchlorate liquid material is concentrated, the driving assembly is closed, and the outlet pipe 21 is opened to discharge the concentrated ammonium perchlorate liquid material.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
