Description

Technical Field

[0001] This utility model relates to the field of ammonium perchlorate production, and in particular to a crystallization apparatus for preparing ammonium perchlorate. Background Technology

[0002] Ammonium perchlorate is one of the most commonly used oxidizers in solid propellants. It is a white crystalline solid and hygroscopic. It can explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powders. Contact with strong acids poses a risk of combustion and explosion.

[0003] In the production of ammonium perchlorate, the ammonium perchlorate solution needs to undergo processes such as evaporation and concentration, crystallization, drying, and crystallization. During the crystallization process, the crystals tend to adhere to the crystallization container, requiring subsequent cleaning, which is quite troublesome.

[0004] Therefore, it is necessary to propose a crystallization apparatus for the preparation of ammonium perchlorate to solve the above problems. Utility Model Content

During the crystallization process, the crystals tend to adhere to the crystallization container, requiring subsequent cleaning, which is quite troublesome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crystallization apparatus for preparing ammonium perchlorate, comprising a crystallization tank, a top cover being provided at the top of the crystallization tank, a motor being fixed at the top of the top cover, a drive shaft being provided at the bottom of the motor, the bottom of the drive shaft extending into the interior of the crystallization tank, a stirring plate being fixed on the outside of the drive shaft, a pulsating soft column being fixed on the side of the stirring plate away from the drive shaft, an inner liner being provided inside the crystallization tank, a support rod being fixed on the inner wall of the inner liner, a collision plate being fixed at the end of the support rod, and the pulsating soft column contacting the collision plate.

[0007] Preferably, a conical hopper is provided at the bottom of the inner liner, with the tip of the conical hopper facing downwards. Multiple drainage holes are provided at the top of the conical hopper. A right-angled triangle is fixed to the bottom of the outer side of the drive shaft. The right-angled side of the right-angled triangle is fixed to the outer side of the drive shaft, and the hypotenuse of the right-angled triangle is attached to the inner side of the conical hopper.

[0008] Preferably, an electric heating tube is provided between the inner side of the crystallization tank and the outer side of the inner liner, and the electric heating tube is sleeved on the outer side of the inner liner.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1 - Figure 4 The crystallization apparatus for preparing ammonium perchlorate shown includes a crystallization tank 1. The top of the outer side of the crystallization tank 1 is provided with a feed inlet 4 and the bottom of the crystallization tank 1 is provided with a discharge outlet 6. The crystallization tank 1 is provided with an inner liner 16. The feed inlet 4 and the discharge outlet 6 are both connected to the inside of the inner liner 16. The ammonium perchlorate solution to be crystallized can be fed into the inside of the inner liner 16 from the feed inlet 4. After crystallization, the crystals can be discharged from the discharge outlet 6.

[0024] The top of the crystallization tank 1 is provided with a top cover 2, and a motor 3 is fixed to the top of the top cover 2. A drive shaft 9 is provided at the bottom of the motor 3. The bottom of the drive shaft 9 extends into the interior of the crystallization tank 1. A stirring plate 10 is fixed to the outside of the drive shaft 9. An electric heating tube 17 is provided between the inside of the crystallization tank 1 and the outside of the inner liner 16. The electric heating tube 17 is sleeved on the outside of the inner liner 16. The electric heating tube 17 can heat the ammonium perchlorate solution in the inner liner 16, causing the water inside the ammonium perchlorate solution to evaporate and be discharged, forming crystals.

[0025] The inner bottom of the inner liner 16 is provided with a conical hopper 7, with the tip of the conical hopper 7 pointing downwards. Multiple leakage holes 8 are opened at the top of the conical hopper 7. The conical hopper 7 can provide a place for the ammonium perchlorate solution to crystallize and support and accumulate the crystals.

[0026] However, during the production of ammonium perchlorate, the ammonium perchlorate solution needs to be evaporated and concentrated to form crystals. These crystals accumulate and adhere to the inner wall and bottom of the crystallization container, which can easily lead to incomplete discharge.

[0027] Therefore, a pulsating soft column 11 is fixed on the side of the stirring plate 10 away from the drive shaft 9, a support rod 13 is fixed on the inner wall of the inner liner 16, and a collision plate 14 is fixed at the end of the support rod 13. The pulsating soft column 11 and the collision plate 14 touch each other. An exhaust port 18 is opened at the top of the top cover 2. The exhaust port 18 is connected to the inside of the inner liner 16. A right-angled triangle plate 12 is fixed at the bottom of the outer side of the drive shaft 9. The right-angled side of the right-angled triangle plate 12 is fixed to the outer side of the drive shaft 9, and the hypotenuse of the right-angled triangle plate 12 is attached to the inner side of the conical bucket 7.

[0028] In the actual operation of this utility model, when the motor 3 is started, the stirring plate 10 can be driven to rotate by the drive shaft 9. The stirring plate 10 can stir the ammonium perchlorate solution inside the inner liner 16. Combined with the heating effect of the electric heating tube 17, the evaporation efficiency can be improved and the time required for crystallization can be reduced.

[0029] When the stirring plate 10 rotates, it will cause the agitator 11 to collide with the collision plate 14 intermittently. The collision will generate vibration, which will be transmitted to the inner wall of the inner liner 16. The force of the vibration will cause the solution or crystals adhering to the inner wall of the inner liner 16 to fall off, making it easier to discharge and reducing the need for subsequent manual cleaning.

[0030] At the same time, when the crystals accumulate and adhere on the conical hopper 7, the rotation of the drive shaft 9 can drive the right-angled triangle plate 12 to rotate against the inner side of the conical hopper 7, thereby sweeping the crystals and allowing them to be discharged from the drain hole 8, thus playing a role in cleaning and discharging.

[0031] Four support legs 5 are fixed to the bottom outer side of the crystallization tank 1, and the four support legs 5 are arranged around the outside of the crystallization tank 1. A vibrator 15 is fixed to the outside of the crystallization tank 1, and the vibrator 15 is activated. This can increase the vibration effect inside the crystallization tank 1, and can be used selectively as needed.
