[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] The present utility model provides an assembled evaporation concentrator as shown in Figures 1 - 3 which includes a heater 1. The heater uses a commercially available heater. Such equipment is a conventional device, so it is not limited; the heater 1 is provided with heating mechanisms such as an electric heating plate inside, which can heat the gas.

[0021] The heater 1 is arranged at the bottom of the evaporation tank 2, and the evaporation tank 2 stores materials. When the heater 1 works, it heats the materials in the evaporation tank 2; the materials are, for example, a solution for evaporative crystallization of ammonium perchlorate.

[0022] A tank cover 9 is arranged at the top of the evaporation tank 2. A sealing ring is arranged between the evaporation tank 2 and the tank cover 9. A charging pipe 10 is arranged on the tank cover 9. The charging pipe 10 is communicated with the evaporation tank 2. A manual opening and closing valve 11 is arranged in the charging pipe 10 to facilitate the entry and exit of materials in the evaporation tank 2.

[0023] In order to solve the problems that the method of stirring through complex structures such as stirring rods increases the equipment cost and is not easy to clean, a flexible hose 5 is arranged inside the evaporation tank 2 of the present utility model. The flexible hose 5 is arranged at the end of the pipeline where the heating gas enters the inside of the evaporation tank 2; when working, when the hot air flow enters the flexible hose 5 through the pipeline, since the flexible hose 5 is made of soft material, the speed of the hot air flow usually fluctuates within a certain range. Therefore, when the hot air flow is discharged into the evaporation tank 2 from the end of the flexible hose 5, the flexible hose 5 will swing, so that the hot air flow blows in different directions and can stir the solution, making the solution heated evenly and enabling better evaporation and crystallization of ammonium perchlorate; it replaces the method of using complex structures such as stirring rods to stir sufficiently in the prior art, optimizes the structure, and increases the contact area between the hot air flow and the solution, thereby improving the processing efficiency; based on the arrangement of the flexible hose 5, the hot air flow entering the evaporation tank 2 can be used to stir the materials, simplifies the structure in the evaporation tank 2, and makes the evaporation tank 2 easy to clean.

[0024] Furthermore, puncture needles 6 are arranged on the inner wall of the evaporation tank 2. When the hot air flow is discharged into the evaporation tank 2 from the end of the flexible hose 5, the hot air flow forms bubbles in the solution. When the bubbles are relatively large, there will be problems such as small contact area between the hot air flow and the solution and low heat exchange efficiency. Therefore, based on the fact that the flexible hose 5 will swing when the hot air flow is discharged into the evaporation tank 2 from the end of the flexible hose 5, the bubbles can contact the puncture needles 6 and be pricked into smaller bubbles, which can not only increase the contact area between the hot air flow and the solution, but also facilitate the rapid rise of the gas and improve the evaporation efficiency.

[0025] Specifically, in actual use, ammonium perchlorate with a relatively low concentration is added into the evaporation tank 2. An air pump 3 is arranged at the top on one side of the heater 1. The air inlet of the air pump 3 is communicated with the heater 1. An air outlet pipe 4 is connected to the air outlet of the air pump 3. One end of the air outlet pipe 4 extends into the inside of the evaporation tank 2, and the end of the air outlet pipe 4 is connected to the flexible hose 5; when working, the heater 1 generates hot air flow inside. When the air pump 3 is started, the hot air flow is discharged into the inside of the evaporation tank 2 through the air outlet pipe 4 and the flexible hose 5 in sequence.

[0026] A condensation tank 8 is provided on one side of the evaporation tank 2. A connecting pipe 7 is connected between the evaporation tank 2 and the condensation tank 8, and a solenoid valve is provided on the connecting pipe 7. The condensation tank 8 can condense and collect steam. Such equipment belongs to existing equipment, so it will not be elaborated here.
