[0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that possess properties such as toxicity, corrosiveness, explosiveness, flammability, and oxidizing properties, posing a threat to human health, facilities, and the environment. Hazardous chemicals can be broadly classified into: explosive precursors, such as potassium nitrate, potassium permanganate, potassium chlorate, sulfuric acid, hydrochloric acid, sulfur, phosphorus, aluminum, and magnesium; toxic precursors, such as acetic anhydride and ephedrine; highly toxic chemicals, such as potassium cyanide, phosphorus trichloride, sodium cyanide, and vanadium pentoxide; flammable and explosive chemicals, such as liquefied petroleum gas, nitroglycerin, rocket fuel, trinitrotoluene (TNT), triethylaluminum, and hydrogen peroxide.

[0003] Traditional chemical mixing tanks often rely on manual feeding, which makes it difficult to control the amount of material added, easily leading to mixing errors. Mixing deviations can trigger violent reactions such as explosions and temperature spikes, posing risks to personnel and equipment safety. Utility Model Content

[0004] Given that traditional chemical mixing reactors often rely on manual feeding, which makes it difficult to control the amount of material added and easily leads to mixing errors, and that mixing deviations can easily trigger violent reactions such as explosions and temperature spikes, posing risks to personnel and equipment safety, this utility model was proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a preparation vessel for hazardous chemicals, including a reaction vessel, a control component at the upper end of the reaction vessel, the control component including a fixed plate fixedly mounted on the upper end of the reaction vessel, a rotating plate inserted in the inner cavity of the fixed plate, four sets of mutually symmetrical control chambers evenly and symmetrically opened on the outer wall of the rotating plate, a feeding port and a discharge port respectively opened at the upper and lower ends of the fixed plate, four sets of mutually symmetrical electric telescopic rods fixedly mounted in the middle of the rotating plate, the extended ends of the electric telescopic rods passing through the control chambers and connected to piston plates, a movable rod opened at the upper end of the reaction vessel below the discharge port, a stepper motor fixedly mounted on one side of the outer wall of the control component, a first bevel gear fixedly mounted in the middle of the rotating plate, a second bevel gear at the lower end of the first bevel gear, a rotating shaft at the lower end of the second bevel gear, a collar sleeved on the outer wall of the rotating shaft, a stirring blade on the outer wall of the collar, and a discharge valve connected to the lower end of the reaction vessel.

[0008] In a preferred embodiment of the hazardous chemical preparation vessel of this utility model, the output end of the stepper motor moves through the outer wall of the fixed disk and is fixedly connected to the middle of the rotating disk.

[0009] In a preferred embodiment of the hazardous chemical preparation vessel of this utility model, the first bevel gear and the second bevel gear mesh with each other, the rotating shaft is rotatably inserted into the middle of the reaction vessel, the collar is movably sleeved on the outer wall of the rotating shaft, the outer wall of the rotating shaft is fixedly provided with a sliding rod, and the inner wall of the collar is provided with a sliding groove that cooperates with the sliding rod.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0017] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a preparation vessel for hazardous chemicals, including a reaction vessel 1. A control component 2 is provided at the upper end of the reaction vessel 1. The control component 2 includes a fixed plate 21 fixedly installed at the upper end of the reaction vessel 1. A rotating plate 22 is inserted into the inner cavity of the fixed plate 21. Four sets of mutually symmetrical control chambers 23 are evenly and symmetrically opened on the outer wall of the rotating plate 22. A feeding port 24 and a discharge port 27 are respectively opened at the upper and lower ends of the fixed plate 21. Four sets of mutually symmetrical electric telescopic rods 25 are fixedly installed in the middle of the rotating plate 22. The extended ends of the electric telescopic rods 25 pass through the control chambers 23 and are connected to piston plates 26. A movable rod 3 is opened at the upper end of the reaction vessel 1 below the discharge port 27. A stepper motor 14 is fixedly installed on one side of the outer wall of the control component 2.

[0018] The rotating disk 22 is movably inserted into the inner cavity of the fixed disk 21, and the outer wall of the rotating disk 22 is in contact with the inner wall of the fixed disk 21. The piston plate 26 is movably inserted into the inner wall of the control chamber 23, and the outer wall of the piston plate 26 is in contact with the inner wall of the control chamber 23. The output end of the stepper motor 14 moves through the outer wall of the fixed disk 21 and is fixedly connected to the middle end of the rotating disk 22.

[0019] By controlling the electric telescopic rod 25 to drive the piston plate 26 to slide along the inner wall of the metering chamber 23, the volume of the metering chamber 23 can be adjusted. After adjusting to the appropriate volume, the chemical reaction ingredients to be injected are injected into the metering chamber 23 located at the upper end of the rotating disk 22 through the feed port 24, so that the ingredients fill the metering chamber 23. The stepper motor 14 rotates intermittently by 90° each time, and stops rotating for a period of time after each 90° rotation, and then continues to rotate 90° after a period of time, so that each rotation has a certain effect. The quantity control chamber 23 is used for feeding and discharging materials through the feed port 24 and the discharge port 27. When the quantity control chamber 23 containing the ingredients rotates to the lower end of the fixed plate 21 and corresponds to the discharge port 27, the ingredients in the quantity control chamber 23 fall into the reactor 1 through the discharge port 27 and the movable rod 3 under the action of gravity. By adjusting the position of the piston plate 26 in the quantity control chamber 23, the capacity in the quantity control chamber 23 can be precisely adjusted to avoid the problem of excessive or insufficient feeding, which could lead to a violent reaction caused by the deviation in the proportion, thus ensuring the safety of personnel and equipment. Example 2

[0020] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a first bevel gear 4 is fixedly provided at the middle end of the rotating disk 22, a second bevel gear 5 is provided at the lower end of the first bevel gear 4, a rotating shaft 6 is provided at the lower end of the second bevel gear 5, a collar 7 is sleeved on the outer wall of the rotating shaft 6, a stirring blade 9 is provided on the outer wall of the collar 7, and a discharge valve 13 is connected to the lower end of the reaction vessel 1.

[0021] The first bevel gear 4 and the second bevel gear 5 mesh with each other. The rotating shaft 6 is inserted into the middle of the reactor 1. The collar 7 is movably sleeved on the outer wall of the rotating shaft 6. The outer wall of the rotating shaft 6 is fixedly provided with a slide rod 8. The inner wall of the collar 7 is provided with a sliding groove that cooperates with the slide rod 8.

[0022] A scraper 10 is fixedly provided at the end of the stirring blade 9 away from the collar 7, and the scraper 10 is in contact with the inner wall of the reactor 1.

[0023] A first magnet 11 is fixedly provided on the upper end of the outer wall of the collar 7, and four sets of second magnets 12 are uniformly fixed on the upper end of the inner wall of the reactor 1. The first magnet 11 and the second magnet 12 have opposite magnetic poles and attract each other.

[0024] During the periodic rotation of the stepper motor 14, the stepper motor 14 drives the rotating disk 22 to rotate, the rotating disk 22 drives the first bevel gear 4 to rotate, the first bevel gear 4 drives the second bevel gear 5 to rotate, and the second bevel gear 5 drives the rotating shaft 6 to rotate. The outer wall of the rotating shaft 6 is provided with a sliding rod 8, and the inner wall of the collar 7 is provided with a sliding groove that cooperates with the sliding rod 8. Thus, the rotating shaft 6 drives the collar 7 to rotate through the sliding rod 8. The collar 7 drives the stirring blade 9 to rotate to stir the reaction ingredients in the reactor 1, so that the ingredients inside the reactor 1 can react fully. As the collar 7 rotates, the first magnet 11 rotates and moves closer to the second magnet 12. Attracted by the magnetic force of the second magnet 12, the first magnet 11 moves closer to the second magnet 12. The first magnet 11 drives the collar 7 to move upward. The groove of the collar 7 slides upward along the slide rod 8. When the first magnet 11 moves away from the second magnet 12 and the gravity is greater than the magnetic force, the collar 7 slides downward along the rotating shaft 6. Thus, during the rotation of the collar 7, the collar 7 moves up and down along the rotating shaft 6. The stirring blade 9 moves up and down accordingly, improving the mixing and reaction rate of the internal ingredients. The scraper 10 can scrape off the ingredients attached to the inner wall of the reactor 1, allowing them to fall back into the reactor 1 for reaction, avoiding the problem of incomplete reaction.

[0025] The remaining structure is the same as that in Example 1. It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
