Description

Technical Field

[0001] This utility model relates to the field of ammonium perchlorate production technology, and in particular to an efficient ammonium perchlorate dissolution and stirring device. Background Technology

[0002] Ammonium perchlorate is a white crystalline solid used in the manufacture of explosives and fireworks, and as an analytical reagent. In the production of ammonium perchlorate, both raw materials, ammonium chloride and sodium perchlorate, need to be dissolved in water to form a solution for a metathesis reaction. Therefore, a mixing device is required to ensure thorough mixing with water. Chinese utility model patent, authorized publication number "CN217645879U", discloses a stirring and side-wall scraping device for an ammonium perchlorate crystallization vessel. This device includes a stirring shaft inside the crystallization vessel, with its top connected to the output shaft of a stirring motor. The stirring shaft has stirring blades, and its upper and lower sides are fixedly connected to the middle of a connecting plate. The two ends of the connecting plate are rotatably connected to the ends of a rotating shaft. The upper and lower sides of the rotating shaft are fixedly connected to the center of a spur gear. The spur gear meshes with the inner side of a ring gear, which is fixed to the inner wall of the crystallization vessel. The rotating shaft surface has spiral scrapers, with the outer edge of the spiral scrapers contacting the inner wall of the crystallization vessel.

[0003] The above technical solution, by combining the original stirring mechanism with a spiral scraper that can both rotate on its own axis and revolve around the sun, can effectively scrape off the crystals adhering to the inner wall of the crystallization vessel, greatly reducing the probability of annular scale formation on the inner wall of the crystallization vessel and improving the crystallization efficiency. However, the above technical solution still has certain defects. The spur gear and the ring gear are directly exposed inside the crystallization vessel, and the spiral scraper will tumble up and down under the action of the spiral scraper, which makes it difficult to avoid nylon raw material adhering to the spur gear and the ring gear during stirring, hindering their meshing transmission and affecting their stirring effect on ammonium perchlorate. Therefore, this utility model proposes a new solution. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an efficient ammonium perchlorate dissolution and stirring device. This device can solve the problem that the spur gear and the ring gear are directly exposed inside the crystallization kettle, and the spiral scraper will flip up and down, which makes it difficult to avoid nylon raw material sticking to the spur gear and the ring gear during stirring, thus hindering their meshing and transmission and affecting their stirring effect on ammonium perchlorate.

[0030] Please see Figure 1-6 This utility model provides a technical solution: an efficient ammonium perchlorate dissolving and stirring device, including an ammonium perchlorate stirring tank 1, a drive box 4 installed at the upper end of the ammonium perchlorate stirring tank 1, a drive assembly disposed inside the drive box 4, and a stirring assembly disposed inside the ammonium perchlorate stirring tank 1. The stirring assembly includes a rotating shaft 10 disposed inside the ammonium perchlorate stirring tank 1, and first stirring blades 13 fixedly connected to the surface of the rotating shaft 10. A fixed cylinder 15 is provided at the lower end of the sealing disc 9, and multiple first connecting plates 16 are fixedly connected to the upper end of the fixed cylinder 15. The multiple first connecting plates 16 are all connected to the sealing disc 9. The sealing plate 9 is fixedly connected, and the lower end of the fixed cylinder 15 is fixedly connected to the second connecting plate 17. The second connecting plate 17 is rotatably connected to the rotating shaft 10. The surface of the fixed cylinder 15 is fixedly connected to the third stirring blade 18. The driving assembly includes a driving motor 7, which is fixedly connected to the upper end of the driving box 4. The output end of the driving motor 7 is fixedly connected to the turntable 8, which is rotatably connected to the rotating shaft 10. The surface of the rotating shaft 10 is fixedly connected to the gear 11. The inner wall of the driving box 4 is fixedly connected to the gear ring 12, which meshes with the gear 11. The inside of the driving box 4 is rotatably connected to the sealing plate 9, and the rotating shaft 10 is rotatably connected to the sealing plate 9.

[0031] There are two stirring components, each symmetrically arranged inside the ammonium perchlorate stirring tank 1.

[0032] There are two of each of the rotating shaft 10 and gear 11, which are symmetrically arranged on the left and right sides of the sealing disc 9.

[0033] A heating plate 2 is fixedly connected to the lower end of the ammonium perchlorate mixing tank 1, a support base 3 is fixedly connected to the lower end of the heating plate 2, and an ammonium perchlorate discharge pipe 6 is fixedly connected to the lower end of the ammonium perchlorate mixing tank 1. The ammonium perchlorate discharge pipe 6 passes through the heating plate 2 and extends out of the support base 3.

[0034] An ammonium perchlorate feed pipe 5 is fixedly connected to the side of the ammonium perchlorate mixing tank 1.

[0035] Scrapers 19 are fixedly connected to the opposite sides of both fixed cylinders 15.

[0036] Multiple second stirring blades 14 are fixedly connected to the lower end surfaces of both rotating shafts 10.

[0037] When using this device, the ammonium perchlorate high-efficiency dissolving and stirring device is first used to transport ammonium perchlorate and water and other raw materials to the ammonium perchlorate stirring tank 1 through the ammonium perchlorate feed pipe 5.

[0038] Start the drive motor 7 inside the drive box 4. The drive motor 7 drives the turntable 8 at the output end to rotate. Since the turntable 8 is rotatably connected to the rotating shaft 10, the rotation of the turntable 8 will cause the rotating shaft 10 to rotate as well. Since the rotating shaft 10 is fixedly connected to the surface of the rotating shaft 10, and the gear ring 12 fixedly connected to the inner wall of the drive box 4 meshes with the gear 11, the gear 11 rolls on the gear ring 12, thereby driving the rotating shaft 10 to make a circular motion around the central axis of the ammonium perchlorate mixing tank 1, realizing revolution. At the same time, the rotating shaft 10 itself is also rotating.

[0039] During the rotation of the rotating shaft 10, the first stirring blade 13 fixedly connected to its surface rotates accordingly, stirring the ammonium perchlorate and water in the ammonium perchlorate stirring tank 1; and, multiple second stirring blades 14 are fixedly connected to the lower end surfaces of both rotating shafts 10. The second stirring blades 14 stir the ammonium perchlorate from below as the rotating shaft 10 rotates, increasing the stirring range and effect.

[0040] A fixed cylinder 15 is provided at the lower end of the sealing disc 9 and is fixedly connected to the sealing disc 9 by multiple first connecting plates 16. The second connecting plate 17 at the lower end of the cylinder 15 is rotatably connected to the rotating shaft 10. A third stirring blade 18 is fixedly connected to the surface of the fixed cylinder 15. When the fixed cylinder 15 revolves with the rotating shaft 10, it further stirs the ammonium perchlorate in the ammonium perchlorate mixing tank 1. The interior of the fixed cylinder 15 cooperates with the first stirring blade 13 to accommodate the transport of ammonium perchlorate, improve the vertical stirring of ammonium perchlorate, and make the ammonium perchlorate better mixed during the stirring process.

[0041] In addition, the sealing plate 9 seals the space between the ammonium perchlorate mixing tank 1 and the drive box 4 to prevent splashing of ammonium perchlorate during the dissolution and stirring of ammonium perchlorate from affecting the gears 11 and gear ring 12 in the drive box 4, ensuring normal meshing and transmission of the gears 11 and gear ring 12, and maintaining stable operation of the stirring device.

[0042] The scrapers 19 are fixedly connected to the back of both fixed cylinders 15. When the fixed cylinders 15 rotate, they can scrape off the ammonium perchlorate adhering to the inner wall of the ammonium perchlorate mixing tank 1, so as to avoid the accumulation of ammonium perchlorate on the tank wall and affect the stirring effect and dissolution efficiency. At the same time, the scrapers 19 also assist in stirring the ammonium perchlorate during the movement.

[0043] When ammonium perchlorate is dissolved and stirred, heating plate 2 is activated to heat the ammonium perchlorate solution, further improving the dissolution efficiency of ammonium perchlorate. After the ammonium perchlorate is dissolved, the ammonium perchlorate discharge pipe 6 is opened. Under the action of gravity, the uniformly stirred ammonium perchlorate solution passes through the ammonium perchlorate discharge pipe 6, passes through the heating plate 2 and extends out to the support base 3, and is discharged from the ammonium perchlorate stirring tank 1, completing the entire process of ammonium perchlorate dissolution, stirring and discharge.

[0044] Furthermore, during the dissolution and stirring process of ammonium perchlorate, some splashing ammonium perchlorate solution or powder will be generated. The sealing disc 9 acts as a seal between the ammonium perchlorate stirring tank 1 and the drive box 4, effectively preventing these splashed materials from entering the drive box 4 and preventing the ammonium perchlorate solution or powder from adhering to the gear 11 and gear ring 12. In addition, the use of the sealing disc 9 in conjunction with the turntable 8 facilitates the improvement of the stability of the rotating shaft 10 during its rotation and revolution, ensuring that the gear 11 rolls smoothly on the gear ring 12, maintaining the stable operation of the entire stirring device, and improving production efficiency and product quality.

[0045] The first stirring blade 13 is fixed to the surface of the rotating shaft 10. As the rotating shaft 10 revolves and rotates, it can stir the ammonium perchlorate at multiple positions and angles within the ammonium perchlorate stirring tank 1. Meanwhile, the third stirring blade 18 on the surface of the fixed cylinder 15, when the fixed cylinder 15 revolves with the rotating shaft 10, and the fixed cylinder 15 and the first stirring blade 13 work together to transport the solution from the bottom of the ammonium perchlorate stirring tank 1 to the top of the ammonium perchlorate stirring tank 1, further expands the stirring range and agitates the ammonium perchlorate from different spatial positions. This makes the stirring no longer limited to a certain area, increases the range and dimension of the stirring, and allows the ammonium perchlorate and water and other raw materials to be mixed more thoroughly.
