[0002] Unsymmetrical dimethylhydrazine is an important chemical product, mainly used as a high-energy fuel. In order to reduce production costs, dimethylamine is usually reacted with nitrogen tetroxide to produce unsymmetrical dimethylhydrazine and water.

DETAILED DESCRIPTION

[0041] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0042] The utility model provides a unilateral dimethylhydrazine extraction device, according to the attached manual Figure 1 To Attachment Figure 4 It can be seen that a UDMH extraction device mainly includes the following parts or components: a mixing tank 10, a lifting seat 30, a first rotating shaft 32, a first driving shaft 35, and a first stirring shaft 36. The connection relationship of each part or component is as follows:

[0043] The mixing tank 10 is provided with a feed port 11 and a discharge port 12, respectively, and a jacket 13 is provided on the outside. The jacket 13 is provided with a water inlet pipe 14 and a water outlet pipe 15 connected thereto. The water inlet pipe 14 and the water outlet pipe 15 are connected to the cooling mechanism for cooling the condensed water. The lifting seat 30 is lifted and arranged above the mixing tank 10 under the action of the lifting mechanism 31. The lifting seat 30 is provided with a first horizontal plate 301, a second horizontal plate 302, and a vertical plate 303 connecting the first horizontal plate 301 and the second horizontal plate 302 in parallel. The first rotating shaft 32 is rotatably arranged on the second horizontal plate 302 under the drive of the first motor 33, and its lower end vertically penetrates the mixing tank 10, and is provided with a containing box 34; the first driving shaft 35 is arranged on the first horizontal plate 301, and its lower end penetrates the first rotating shaft 32 and extends into the containing box 34; the first stirring shaft 36 is horizontally arranged in the mixing tank 10 and is connected to the rotating shaft of the containing box 34, and a first bevel gear 37 is arranged on the first stirring shaft 36 in the containing box 34, and the first bevel gear 37 is meshed with the second bevel gear 38 at the lower end of the first driving shaft 35.

[0044] After the solution is injected into the mixing tube through the feed port 11, the first motor 33 can be used to drive the first rotating shaft 32 to rotate. When the first rotating shaft 32 rotates, the first stirring shaft 36 is driven to rotate with the first rotating shaft 32 as the center, and with the cooperation of the first bevel gear 37 and the second bevel gear 38, the first stirring shaft 36 is driven to rotate with itself as the center, so as to stir the solution and accelerate the reaction between the solutions. When the first stirring shaft 36 rotates, the lifting seat 30 can be lifted and lowered under the action of the lifting mechanism 31, and drive the first stirring shaft 36 to lift and lower, so that the first stirring shaft 36 can stir solutions at different heights, thereby greatly improving production efficiency.

[0045] The condensed water after heating in the jacket 13 will flow into the cooling mechanism through the drain pipe. Under the action of the cooling mechanism, it will be quickly cooled and then flow into the jacket 13 again through the water inlet pipe 14, so as to realize the recycling of water resources and save water resources. It can also take away the heat in the mixing tank 10 in time, avoid the reaction from getting out of control, resulting in the increase of temperature and pressure, and reduce the risk of explosion.

[0046] As an embodiment, according to the attached Figure 3 It can be seen that the lifting mechanism 31 includes: a first guide rod 311 is vertically arranged on the mixing tank 10, and is slidably connected to and penetrates the lifting seat 30; a reciprocating screw 312 is arranged on the mixing tank 10 in parallel with the first guide rod 311, and rotates under the drive of the second motor 313, and the reciprocating screw 312 is threadedly connected to and penetrates the lifting seat 30.

[0047] The reciprocating screw 312 is threadedly connected to the lifting seat 30. When the second motor 313 drives the reciprocating screw 312 to rotate, the lifting seat 30 can be driven to lift and reciprocate. The threaded connection can provide smooth and stable movement, and the threaded fit can withstand a large axial load, which enables the mechanism to carry heavy objects while maintaining high precision. When the second motor 313 drives the reciprocating screw 312 to rotate, the lifting seat 30 can keep the load fixed in place to ensure safety.

[0048] As an embodiment, according to the attached Figure 2 It can be seen that the first motor 33 is arranged on the horizontal plate, and the output end thereof is provided with a third bevel gear 40, and the fourth bevel gear 41 provided on the upper end of the first rotating shaft 32 is meshed with the third bevel gear 40. The first driving shaft 35 is connected to the rotating shaft of the first horizontal plate 301, and the first driving shaft 35 is provided with a fifth bevel gear 42, which is installed in the opposite direction to the fourth bevel gear 41 and meshes with the fourth bevel gear 41.

[0049] When the first motor 33 drives the third bevel gear 40 to rotate, it can also drive the fourth bevel gear 41 and the fifth bevel gear 42 to rotate in opposite directions, thereby causing the first rotating shaft 32 and the first driving shaft 35 to rotate in opposite directions. At this time, the second bevel gear 38 on the first rotating shaft 32 can drive the first bevel gear 37 to rotate faster, thereby increasing the rotation speed of the first stirring shaft 36 and further improving the stirring efficiency.

[0050] As an embodiment, according to the attached Figure 1 It can be seen that the cooling mechanism includes: the top of the cooling box 21 is connected to one end of the water outlet pipe 15, and the bottom is connected to one end of the water inlet pipe 14; the stirring mechanism 22 is arranged in the cooling box 21 to accelerate the cooling of the cooling water. The condensed water in the jacket 13 can enter the cooling box 21 through the drain pipe, and the condensed water is stirred by the stirring mechanism 22 to increase the contact area between the condensed water and the air, thereby improving the heat exchange efficiency and the cooling efficiency of the condensed water, thereby ensuring that the temperature of the solution is not too high during mixing, and ensuring production efficiency.

[0051] In this embodiment, according to the specification Figure 1 It can be seen that a filter plate 24 is horizontally arranged in the cooling box 21. The condensed water after heating contains dissolved minerals, and after the condensed water is heated, it will precipitate out of the water to form solid impurities. The filter plate 24 can intercept these impurities to prevent the impurities from clogging the pipeline and affecting the cooling effect.

[0052] In this embodiment, according to the specification Figure 1It can be seen that a diverter 25 is provided on the top of the cooling box 21, and one end of the water outlet pipe 15 is connected to the diverter 25. The diverter 25 can evenly distribute cooling water to different areas of the cooling box 21, which helps to ensure uniform temperature throughout the cooling box 21, thereby improving cooling efficiency, and by evenly distributing condensed water, the diverter 25 helps to improve the heat exchange efficiency in the cooling box 21, so that heat can be more effectively discharged from the condensed water.

[0053] In this embodiment, according to the specification Figure 4 It can be seen that the stirring mechanism 22 includes: a second stirring shaft 221 is horizontally arranged in the cooling box 21, a first end is connected to and penetrates the rotating shaft of the cooling box 21, and a first gear 222 is arranged; a connecting frame 223 is slidably arranged on the cooling box 21, and a first rack 224 arranged thereon is meshed with the first gear 222; a third motor 225 is arranged on the cooling box 21, and is connected to the connecting frame 223 through a transmission assembly, and is used to drive the connecting frame 223 to slide back and forth.

[0054] In this embodiment, according to the specification Figure 4 It can be seen that the transmission assembly includes: a rotating disk 231 is arranged at the output end of the third motor 225, and an eccentric shaft 232 is eccentrically arranged thereon; a first end of a transmission rod 233 is connected to the rotating shaft of the eccentric shaft 232, and a second end is hinged to the connecting frame 223.

[0055] When the third motor 225 drives the rotating disk 231 to rotate, the eccentric shaft 232 can drive the connecting frame 223 to slide back and forth through the transmission rod 233. The first rack 224 arranged thereon will drive the first gear 222 to rotate alternately forward and reverse, and then drive the second stirring shaft 221 to rotate alternately forward and reverse on the condensed water, thereby promoting the heat exchange process more evenly.

[0056] In this embodiment, the discharge port 12 at the bottom of the mixing tank 10 is tilted to facilitate the discharge of the unsymmetrical dimethylhydrazine in the mixing tank 10 .
