Description

Technical Field

[0001] This utility model belongs to the field of ammonium perchlorate processing technology, and in particular relates to a vacuum crystallizer for ammonium perchlorate that is easy to clean and dry. Background Technology

[0002] Ammonium perchlorate is an inorganic compound with the chemical formula NH4ClO4. It is a white crystalline powder that is hygroscopic. Ammonium perchlorate is a strong oxidizing agent and can explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powders. It poses a risk of combustion and explosion when in contact with strong acids. It is used in the manufacture of explosives and fireworks, and as an analytical reagent.

[0003] After ammonium perchlorate undergoes vacuum crystallization in a tank, residual crystals adhere to the inside of the tank. Failure to clean the inside of the tank in a timely manner will affect the usability of the next crystallization operation. Utility Model Content

[0004] This invention addresses the problem in existing technologies where residual crystals adhere to the inside of the tank, and failure to clean the tank interior promptly affects the usability of subsequent crystallization operations. The following technical solution is proposed:

[0005] An ammonium perchlorate vacuum crystallizer that is easy to clean and dry includes: a tank body, a fixing frame fixedly installed on the outer surface of the tank body, a tank cover provided at the top of the tank body, a discharge pipe fixedly connected to the bottom of the tank body, a discharge valve fixedly installed on the discharge pipe, a drive motor fixedly installed at the top of the tank cover, and a vacuum pump fixedly installed at the bottom of the tank body.

[0006] The top of the can lid is fixedly connected to a feed pipe at one side of the drive motor. The output end of the drive motor is fixedly connected to a rotating shaft. Several stirring blades are symmetrically fixedly connected to the outer surface of the rotating shaft. Two fixing rings are fixedly sleeved on the outer surface of the rotating shaft. Four fixing rods are symmetrically fixedly connected between the two fixing rings. An inner cylinder is fixedly sleeved on the outer surface of the rotating shaft between the two fixing rings. An outer cylinder is slidably sleeved on the outer surface of the inner cylinder. A lead screw is threadedly connected inside the outer cylinder.

[0007] As a preferred embodiment of the above technical solution, the lead screw passes through two fixed rings, and the lead screw is rotatably connected to the inside of the fixed rings via bearings.

[0008] As a preferred embodiment of the above technical solution, the outer cylinder is slidably sleeved on the outer surface of the rotating shaft.

[0009] As a preferred embodiment of the above technical solution, the surface of the inner cylinder is provided with fine holes.

[0010] As a preferred embodiment of the above technical solution, a hot air blower is fixedly installed on the top of the can lid, and an air duct is fixedly connected to one side of the hot air blower, with the end of the air duct away from the hot air blower fixedly penetrating through the can lid.

[0011] As a preferred embodiment of the above technical solution, the outer surface of the rotating shaft is symmetrically fixedly connected with a support frame, and a cleaning brush is fixedly connected to the outer surface of each of the two support frames, with both cleaning brushes adhering to the inner wall of the tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) This utility model uses an inner cylinder and an outer cylinder inside the tank. When the tank is crystallizing, the outer cylinder is completely fitted onto the outer surface of the inner cylinder, so that the fine pores of the inner cylinder are completely blocked. The inner cylinder is filled with a cleaning solution for cleaning ammonium perchlorate. After the ammonium perchlorate crystallization operation is completed, the end cap is opened and the screw is rotated to move the outer cylinder downward, thereby exposing the fine pores of the inner cylinder. Then the motor is started to make the inner cylinder move and rotate with the rotating shaft, thereby splashing the cleaning solution inside the inner cylinder onto the inner wall of the tank, thereby softening and falling off the crystals remaining on the inner wall of the tank.

[0014] (2) This utility model uses a cleaning brush to remove the softened but unfallen crystals from the inner wall of the tank, thus cleaning the internal environment of the tank and providing a good crystallization environment for the next crystallization operation.

[0015] (3) This utility model uses a hot air blower to dry the inner wall of the tank after the residual crystals inside the tank have been cleaned, so that the residual moisture inside the tank can be evaporated quickly. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] This invention provides a vacuum crystallizer for ammonium perchlorate that is easy to clean and dry, such as... Figures 1 to 4 As shown, the system includes a tank body 1, a mounting bracket 2 fixedly installed on the outer surface of the tank body 1, a tank cover 3 at the top of the tank body 1, a discharge pipe 4 fixedly connected to the bottom of the tank body 1, a discharge valve 5 fixedly installed on the discharge pipe 4, a drive motor 6 fixedly installed at the top of the tank cover 3, a vacuum pump 9 fixedly installed at the bottom of the tank body 1, an inlet pipe 10 fixedly connected to the top of the tank cover 3 at one side of the drive motor 6, a rotating shaft 11 fixedly connected to the output end of the drive motor 6, several stirring blades 12 symmetrically fixedly connected to the outer surface of the rotating shaft 11, and two fixing rings 13 fixedly sleeved on the outer surface of the rotating shaft 11, with symmetrical connections between the two fixing rings 13. Four fixed rods 14 are fixedly fitted to the outer surface of the rotating shaft 11 between two fixed rings 13. The inner cylinder 15 is filled with cleaning fluid. An outer cylinder 16 is slidably fitted to the outer surface of the inner cylinder 15. The outer cylinder 16 is slidably fitted to the outer surface of the rotating shaft 11. When crystallization is performed, the outer cylinder 16 is completely fitted to the outer surface of the inner cylinder 15, so that the cleaning fluid inside the inner cylinder 15 is blocked and will not flow out. A screw 17 is threadedly connected to the inside of the outer cylinder 16. The screw 17 passes through the two fixed rings 13 and is rotatably connected to the inside of the fixed rings 13 through bearings. By rotating the screw 17, in conjunction with the action of the fixed rods 14, the outer cylinder 16 can slide up and down on the outer surface of the inner cylinder 15.

[0024] like Figure 3 and Figure 4 As shown, the inner cylinder 15 has fine holes 18 on its surface. A plastic valve is installed on the surface of the inner cylinder 15 at the position of the fine hole 18. When the inner cylinder 15 rotates at high speed, the plastic valve is subjected to the force generated by the rotation of the cleaning liquid, which opens the channel of the plastic valve. This allows the cleaning liquid inside the inner cylinder 15 to flow out through the valve, and facilitates the cleaning liquid to splash onto the inner wall of the tank 1 along the fine hole 18, thereby softening the crystals remaining on the inner wall of the tank 1 and causing them to fall off.

[0025] like Figure 1 and Figure 2 As shown, a hot air blower 7 is fixedly installed on the top of the can lid 3. A duct 8 is fixedly connected to one side of the hot air blower 7. The end of the duct 8 away from the hot air blower 7 is fixedly inserted through the can lid 3, so that the hot air generated by the hot air blower 7 enters the interior of the can body 1 to dry the inner wall of the can body 1, thereby rapidly evaporating the moisture inside the can body 1.

[0026] like Figure 2 and Figure 3 As shown, a support frame 19 is symmetrically fixedly connected to the outer surface of the rotating shaft 11. A cleaning brush 20 is fixedly connected to the outer surface of each of the two support frames 19. Both cleaning brushes 20 are attached to the inner wall of the tank 1. By setting the cleaning brushes 20, the rotating shaft 11 rotates, which drives the cleaning brushes 20 to rotate, thereby allowing the cleaning brushes 20 to wash away the crystals attached to the inner wall of the tank 1.

[0027] Working principle: When using this device for crystallization, the outer cylinder 16 is completely fitted onto the outer surface of the inner cylinder 15, preventing the cleaning liquid inside the inner cylinder 15 from flowing out. When cleaning the inside of the tank 1 is required, the tank cover 3 is opened, and then the screw 17 is rotated. Under the action of the fixing rod 14, the outer cylinder 16 moves away from the inner cylinder 15, thereby completely exposing the fine holes 18. Then the tank cover 3 is closed, and the drive motor 6 is started, causing the rotating shaft 11 to rotate, driving the inner cylinder 15 to rotate rapidly. The inside of the inner cylinder 15 then rotates rapidly. The rotating cleaning fluid splashes through the plastic flap onto the inner wall of tank 1, softening and removing the residual crystals. At the same time, the cleaning brush 20 scrapes away the softened but not yet removed crystals from the inner wall of tank 1, causing all the crystals inside tank 1 to fall to the bottom. The discharge valve 5 is opened to drain the wastewater from tank 1, thus cleaning the residual crystals inside. The hot air blower 7 is then activated to quickly dry the inner wall of tank 1 with hot air, facilitating the next crystallization step.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
