Description

Technical Field

[0001] This utility model relates to the field of ammonium perchlorate production, and in particular to a vacuum container for discharging liquid during the preparation of ammonium perchlorate. Background Technology

[0002] Ammonium perchlorate is a white crystalline solid that is hygroscopic and a strong oxidizing agent. It can explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powders. Therefore, ammonium perchlorate solutions are stored in containers under vacuum.

[0003] However, when the container is evacuated after storing ammonium perchlorate solution, the resulting suction can easily cause some of the ammonium perchlorate solution to be extracted, resulting in waste and pollution.

[0004] Therefore, it is necessary to propose a vacuum container for discharging liquid in the preparation of ammonium perchlorate to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum container for preparing ammonium perchlorate, in order to solve the problem that when the container is evacuated after storing ammonium perchlorate solution, the suction force generated can easily cause some of the ammonium perchlorate solution to be extracted, resulting in waste and pollution.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vacuum container for preparing ammonium perchlorate, comprising a vacuum tank, a vacuum pump being provided on one side of the vacuum tank, a pipe connecting the vacuum pump and the vacuum tank, a filter mechanism being provided on the pipe, a water pump being connected to the bottom end of the filter mechanism, a connecting pipe being connected to the bottom end of the water pump, and the connecting pipe being connected to the vacuum tank;

[0007] The filtration mechanism includes a filter box with a V-shaped groove at the bottom inside. A filter plate is slidably disposed inside the filter box, and a scraper is arranged around the outside of the filter plate. The outer side of the scraper is in contact with the inner wall of the filter box. A discharge port is provided on the V-shaped groove and is connected to a water pump. A spring is fixed between the scraper and the inner wall of the filter box on the side near the vacuum tank.

[0008] Preferably, the V-shaped opening of the V-groove is oriented upwards, and multiple discharge ports are provided, which are distributed at equal intervals along the length of the V-groove.

[0009] Preferably, a sliding rod is fixed between the two sides inside the filter box, the sliding rod is distributed along the length of the filter box, and the scraper is slidably disposed on the sliding rod.

[0010] Preferably, a support plate is fixed to the top of the outer side of the vacuum tank, the filter mechanism is fixed to the top of the support plate, and the water pump is fixed to the bottom of the support plate.

[0011] Preferably, an output port is provided at the top of the outer side of the vacuum tank, a first solenoid valve is provided at the connection between the output port and the pipe, and a second solenoid valve is provided at the connection between the connecting pipe and the vacuum tank.

[0012] Preferably, the vacuum tank is provided with a feeding port at the top.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. In the actual operation of this utility model, when the vacuum pump evacuates the vacuum tank, the gas and some of the ammonium perchlorate solution inside the vacuum tank will enter the interior of the filter box through suction and impact the filter plate. The ammonium perchlorate solution will be blocked by the filter plate and will stay there, while the gas will continue to be discharged, thus playing a filtering role and preventing the ammonium perchlorate solution from being discharged.

[0015] 2. Furthermore, the filter plate will move due to the impact of the ammonium perchlorate solution and gas, and will move along the sliding rod. As the filter plate moves, the scraper will scrape the inner wall of the filter box to prevent the liquid from sticking to the inner wall.

[0016] 3. By moving the scraper, the liquid accumulated on the V-shaped groove can be pushed to the discharge port and discharged into the water pump. The water pump then pumps the liquid back into the vacuum tank, completing the automatic collection function and avoiding waste. When the vacuum pump stops, the spring elasticity can automatically drive the filter plate to reset, making it convenient for the next cleaning. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1 - Figure 3 The illustrated vacuum container for preparing ammonium perchlorate includes a vacuum tank 1, a vacuum pump 8 on one side of the vacuum tank 1, and a pipe 7 connecting the vacuum pump 8 and the vacuum tank 1. A feeding port is provided at the top of the vacuum tank 1, through which liquid ammonium perchlorate can be placed inside the vacuum tank 1. When the vacuum pump 8 is started, the gas inside the vacuum tank 1 is extracted to form a vacuum environment, which is used to protect and store the liquid ammonium perchlorate.

[0023] A support plate 3 is fixed to the top of the outer side of the vacuum tank 1. The filter mechanism is fixed to the top of the support plate 3, and the water pump 5 is fixed to the bottom of the support plate 3. The support plate 3 is used to support the filter mechanism and fix the water pump 5.

[0024] Ammonium perchlorate is a white crystalline solid that is hygroscopic and a strong oxidizing agent. It can explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powders. Therefore, ammonium perchlorate solutions are stored in containers under vacuum.

[0025] However, when the container is evacuated after storing ammonium perchlorate solution, the resulting suction can easily cause some of the ammonium perchlorate solution to be extracted, resulting in waste and pollution.

[0026] Therefore, a filter mechanism is installed on the pipe 7. A water pump 5 is connected to the bottom of the filter mechanism. A connecting pipe 6 is connected to the bottom of the water pump 5. The connecting pipe 6 is connected to the vacuum tank 1. The filter mechanism includes a filter box 4. A V-shaped groove 10 is opened at the bottom of the filter box 4. The V-shaped groove 10 facilitates the collection of liquid.

[0027] A filter plate 9 is slidably disposed inside the filter box 4. A scraper 11 is disposed around the outside of the filter plate 9. The outer side of the scraper 11 is in contact with the inner wall of the filter box 4. A discharge port 14 is provided on the V-shaped groove 10. The discharge port 14 is connected to the water pump 5. A spring 12 is fixed between the scraper 11 near the vacuum tank 1 and the inner wall of the filter box 4. A sliding rod 13 is fixed between the two sides inside the filter box 4. The sliding rod 13 is distributed along the length of the filter box 4. The scraper 11 is slidably disposed on the sliding rod 13.

[0028] In the actual operation of this utility model, when the vacuum pump 8 evacuates the vacuum tank 1, the gas and some of the ammonium perchlorate solution inside the vacuum tank 1 will enter the interior of the filter box 4 by suction and impact the filter plate 9. The ammonium perchlorate solution will be blocked by the filter plate 9 and will stay there, while the gas will continue to be discharged, thus playing a filtering role and preventing the ammonium perchlorate solution from being discharged.

[0029] Furthermore, the filter plate 9 will move due to the impact of the ammonium perchlorate solution and gas, and will move along the sliding rod 13. As the filter plate 9 moves, the scraper 11 will scrape the inner wall of the filter box 4 to prevent the liquid from adhering to the inner wall.

[0030] Furthermore, by moving the scraper 11, the liquid accumulated on the V-shaped groove 10 can be pushed to the discharge port 14 and discharged into the water pump 5. The water pump 5 then pumps the liquid back into the vacuum tank 1, completing the automatic collection function and avoiding waste.

[0031] When the vacuum pump 8 stops, the filter plate 9 can be automatically reset by the elastic action of the spring 12, making it convenient for the next cleaning.

[0032] The V-shaped opening of the V-groove 10 is set upward, and multiple discharge ports 14 are provided. The multiple discharge ports 14 are evenly distributed along the length of the V-groove 10, which facilitates the filter plate 9 to push and discharge the material at different positions.

[0033] An output port 2 is provided at the top of the outer side of the vacuum tank 1. A first solenoid valve is provided at the connection between the output port 2 and the pipe 7, and a second solenoid valve is provided at the connection between the connecting pipe 6 and the vacuum tank 1.
