[0020] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0021] like Figure 1-4As shown, a feed preheating device for the production of unsymmetrical dimethylhydrazine includes an outer casing 1, a plurality of inner tanks 2 are assembled inside the outer casing 1, a preheating chamber is provided inside the inner tank 2, a feed group 3 connected to the preheating chamber is provided on the upper side of the inner tank 2, and is used to transport the raw material of unsymmetrical dimethylhydrazine into the interior of the inner tank 2, and a discharge group 4 connected to the preheating chamber is fixedly connected to the lower part of the inner tank 2. When the discharge group 4 is opened, the raw material inside the inner tank 2 can be discharged. The feed group 3 and the discharge group 4 are both a combination of pipes and valves.

[0022] A heat source group is provided inside the outer housing 1, and the heating temperature inside the multiple preheating chambers can be adjusted independently. At this time, multiple raw materials are transported into the multiple preheating chambers respectively, and the multiple raw materials can be preheated at different temperatures inside the multiple preheating chambers.

[0023] Among them, such as Figure 2 As shown, the heating group includes multiple heating units, and the multiple heating units heat the interior of multiple preheating chambers respectively. The temperatures inside the multiple preheating chambers can be adjusted by the multiple heating units, and the raw materials inside can be heated at different temperatures. At this time, the heating of the rest of the space inside the outer casing 1 can be reduced, thereby reducing the waste of heating energy.

[0024] like Figure 2-4 As shown, the heating unit includes multiple outer tanks 9, which are respectively fixedly connected to the outsides of multiple inner tanks 2. A heating chamber is formed between the inner tank 2 and the outer tank 9. A heat transfer medium is provided inside the heating chamber. A heater 11 is fixedly connected to the outside of the outer tank 9. The heater 11 is electrically connected to a heating wire 12 located inside the heating chamber. The inside of the heating wire 12 is heated by the heater 11, and the heat transfer medium can be heated by the heating wire 12. The temperature of the heat transfer medium will be transmitted to the inside of the preheating chamber through the inner tank 2. At this time, the direct contact between the heating unit and the raw material is isolated by the inner tank 2, which can effectively reduce the contamination of the raw material by the heating unit during heating.

[0025] Furthermore, the heat transfer medium may be liquid or gas, preferably water. When water is heated, the water is heated more evenly, thereby being able to heat the raw materials more evenly.

[0026] like Figure 2-3 As shown, the outer tank 9 is also equipped with a temperature sensor 10 for monitoring the temperature inside the preheating chamber. The temperature sensor 10 can be electrically connected to an alarm or a host. When the temperature sensor 10 detects that the temperature inside the preheating chamber is too high, an alarm can be sounded through the alarm, or the host can control the heater 11 to stop heating.

[0027] like Figure 4As shown, in order to make the raw materials inside the preheating chamber heated more evenly, a transmission motor 5 can be fixedly connected to the upper side of the inner tank 2, and the output end of the transmission motor 5 is fixedly connected to a rotating rod 6 located at the axis of the preheating chamber, and the outer side of the rotating rod 6 is fixedly connected to a spiral pusher 7. When the transmission motor 5 is started, the spiral pusher 7 will be driven to rotate through the rotating rod 6. When the spiral pusher 7 rotates, it will push and stir the raw materials inside the preheating chamber, so that the raw materials inside the preheating chamber are evenly contacted with the heat energy inside the preheating chamber.

[0028] like Figure 4 As shown, at least one L-shaped push plate 8 is fixedly connected to the lower part of the rotating rod 6. The L-shaped push plate 8 includes a horizontal plate and a vertical plate. One end of the horizontal plate is fixedly connected to the lower part of the rotating rod 6. The lower end edge of the horizontal plate and the inner wall of the lower side of the preheating chamber are gap-matched. The other end of the horizontal plate is fixedly connected to the lower end of the vertical plate. The edge of the horizontal plate close to the side wall of the preheating chamber and the side wall of the preheating chamber are gap-matched. When the rotating rod 6 rotates, the raw materials at the edge of the preheating chamber will be pushed through the L-shaped push plate 8 to reduce dead angles.

[0029] At the same time, the edges of the horizontal plate and the vertical plate away from the inner wall of the preheating chamber are inclined in the direction opposite to the rotation direction of the L-shaped pusher plate 8. At this time, when the rotating rod 6 drives the L-shaped pusher plate 8 to rotate, the L-shaped pusher plate 8 will push the raw materials at the edge of the preheating chamber toward the spiral pusher 7, thereby better stirring the raw materials.

[0030] The working principle of the present invention is as follows: multiple raw materials of unsymmetrical dimethylhydrazine are respectively transported into the interior of multiple preheating chambers through multiple feeding groups 3, and then the heater 11 is started. After the heater 11 is started, it heats the heat transfer medium through the heating wire 12. The temperature of the heat transfer medium is transmitted to the interior of the preheating chamber through the inner tank 2, thereby heating the interior of the raw material preheating chamber;

[0031] While heating, the transmission motor 5 can be started. After the transmission motor 5 is started, the spiral pusher 7 is driven to rotate through the rotating rod 6. When the spiral pusher 7 rotates, it pushes and stirs the raw materials in the preheating chamber, so that the raw materials in the preheating chamber are evenly exposed to the heat energy in the preheating chamber.

[0032] In summary, the present technical solution preheats a variety of raw materials by setting up multiple preheating chambers with independently adjustable heating temperatures. It can simultaneously perform preheating treatments on a variety of raw materials at different temperatures, which is well adapted to the preheating treatment of unsymmetrical dimethylhydrazine before production feeding, thereby improving the preheating efficiency.

[0033] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
