DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-6As shown, an electric heating reaction kettle for preparing triazine comprises a kettle body 1, a heat-conducting shell 101 is fixedly connected to the surface of the kettle body 1, a heater 104 is arranged inside the kettle body 1, a motor 102 is arranged on the top of the kettle body 1, a stirring rod 103 is fixedly connected to the output shaft of the motor 102, and the lower end of the stirring rod 103 passes through the kettle body 1 and extends to the inside of the kettle body 1; an auxiliary structure 2 is arranged on the surface of the kettle body 1, and the auxiliary structure 2 is used to enhance the heating effect of the raw materials inside the kettle body 1; a protective structure 3, The protective structure 3 is arranged on one side of the kettle body 1, and the protective structure 3 is used to adjust the pressure inside the kettle body 1; wherein, the auxiliary structure 2 includes a liquid storage shell 201 arranged on one side of the kettle body 1, the interior of the liquid storage shell 201 is filled with heat-conducting oil, an oil pump 202 is arranged inside the liquid storage shell 201, the liquid outlet end of the oil pump 202 is connected with a heat-conducting pipe 204, and the other end of the heat-conducting pipe 204 passes through the liquid storage shell 201 and is spirally attached to the surface of the heat-conducting shell 101, and the liquid inlet end of the oil pump 202 is connected with a return pipe 203;

[0024] By starting the oil pump 202, heat transfer oil can be injected into the heat pipe 204, so that the heat dissipated to the outside by the kettle body 1 when heated by the heater 104 can be absorbed under the bonding effect of the heat pipe 204 and the heat shell 101, thereby effectively utilizing this part of the waste heat.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the auxiliary structure 2 also includes a connecting block 206 fixedly connected to the top of the kettle body 1, and two connecting cavities 207 are opened inside the connecting block 206. A flow channel 205 is opened inside the stirring rod 103. The surface of the stirring rod 103 is slidably connected to the inner wall of the connecting block 206. The surface of the stirring rod 103 is opened with two through holes 208 respectively connected to the two connecting cavities 207, one of the through holes 208 is connected to the liquid inlet end of the flow channel 205, and the other through hole 208 is connected to the liquid outlet end of the flow channel 205. One end of the heat conduction pipe 204 away from the liquid storage shell 201 is connected to the upper connecting cavity 207, and the other end of the return pipe 203 is connected to the lower connecting cavity 207.

[0026] After absorbing heat, the heat transfer oil is injected into the connecting cavity 207 connected to it and injected into the flow channel 205 through the through hole 208. During this process, the heat transfer oil can flow inside the flow channel 205 and be injected into the connecting cavity 207 connected to it through another through hole 208. Under the action of the return pipe 203, it is guided back to the interior of the liquid storage shell 201 for reuse. Since the flow channel 205 is arranged inside the stirring rod 103, the raw materials can be heated from the middle during the stirring process, so that the heating effect is more uniform. At the same time, the arrangement of the connecting cavity 207 and the through hole 208 can ensure the normal flow of the heat transfer oil during the rotation of the stirring rod 103.

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the protective structure 3 includes a mounting shell 301 arranged on the other side of the kettle body 1, a partition 305 is fixedly connected to the inner wall of the mounting shell 301, a discharge cavity is formed between one side of the partition 305 and the inner wall of the mounting shell 301, a filter element 304 is fixedly connected to the inner wall of the discharge cavity, a storage cavity is formed between the other side of the partition 305 and the inner wall of the mounting shell 301, and the interior of the storage cavity is filled with spare gas, an exhaust pipe 306 connected to the discharge cavity is arranged on the surface of the mounting shell 301, a mounting pipe 302 is connected to the top of the mounting shell 301, the other end of the mounting pipe 302 is connected to the kettle body 1, and a partition block 303 is fixedly connected to the inner wall of the mounting pipe 302, Two channels are formed between the two sides of the partition block 303 and the inner wall of the mounting tube 302, and the two channels are respectively connected to the discharge chamber and the storage chamber. The two channels, and the inner walls of the two channels respectively connected to the discharge chamber and the storage chamber are fixedly connected with mounting blocks 307, the two mounting blocks 307 are staggered, and one side of the mounting block 307 is fixedly connected with a connecting column 309, and the surface of the connecting column 309 is slidably connected with a sealing block 308, the two sealing blocks 308 are staggered, and the surface of the connecting column 309 is provided with a through groove 310 located between the sealing block 308 and the mounting block 307, and a spring 311 is fixedly connected between the sealing block 308 and the mounting block 307;

[0028] During the preparation of the product, the pressure inside the kettle body 1 will change with the internal reaction. When the pressure is too high, the gas will pass through one of the channels and push the sealing block 308 to make it slide down along the connecting column 309 connected to it while compressing the spring 311. When the sealing block 308 moves to the middle of the through groove 310, the gas can pass through the through groove 310 and pass through the sealing block 308 to enter the inside of the discharge cavity. After being filtered by the filter element 304, the gas is discharged through the exhaust pipe 306. When the pressure inside the kettle body 1 is too low, the pressure of the standby gas filled in the gas storage cavity is greater than the pressure inside the kettle body 1, so that the standby gas enters the inside of the channel connected to it. In this process, the sealing block 308 is pushed to the middle of the through groove 310, so that the standby gas can be injected into the inside of the kettle body 1, thereby achieving the effect of compensating the air pressure and avoiding the situation where the pressure difference between the inside and the outside is large and damages the kettle body 1. At the same time, the standby gas can preferably use the gas used in the preparation process, such as ammonia.

[0029] When the utility model is in use, the heat transfer oil can be injected into the interior of the heat transfer pipe 204 by starting the oil pump 202, so that under the fitting effect of the heat transfer pipe 204 and the heat transfer shell 101, the heat radiated to the outside when the kettle body 1 is heated by the heater 104 can be absorbed and injected into the interior of the connecting cavity 207 connected thereto and injected into the flow channel 205 through the through hole 208. During this process, the heat transfer oil can flow inside the flow channel 205 and heat the raw materials from the middle during the stirring process, so that the heating effect is more uniform. At the same time, the protection structure 3 is provided to prevent the kettle body 1 from being damaged due to excessive internal and external pressure difference during the preparation process.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
