It can also be used as an accelerator for vinyl compound polymerization rubber and anaerobic adhesives, as well as a plastic curing agent, a chemical reaction deacidification agent, a metal preservative, etc. It is also used as a raw material for the manufacture of triphenylmethane dyes, azo dyes, basic dyes, tetraethyl ketone, medicines and color developers.

[0003] In the production process of diethylaniline as a raw material, an external circulation cooling device is usually required for cooling. However, the existing external circulation cooling device is integrated with the reactor during use, which makes it inconvenient to disassemble and assemble. When a problem occurs in the equipment and it needs to be repaired, the workload will be very large. The equipment needs to be dismantled as a whole for repair. The installation is also relatively complicated, time-consuming and labor-intensive, which affects work efficiency. Therefore, a production external circulation mechanism is proposed to solve the above problems. Utility Model Content

[0007] Furthermore, a liquid injection port is provided on one side of the heat preservation sleeve close to the return pipe and the connecting pipe, and a stopper is fixedly connected to the outer side of the liquid injection port and the end of the cooling pipe.

[0008] Furthermore, the outer sides of the liquid injection port and the end of the cooling pipe are both provided with external threads, and the external threads cooperate with the threads on the inner wall of the threaded ring.

[0009] Furthermore, one end of the cooling pipe located inside the reactor is spiral and is located outside the stirring shaft, and the reflux pipe, the delivery pipe and the connecting pipe are all soft pipes.

[0010] Furthermore, the cross section of the thermal insulation sleeve is U-shaped, the heat conducting plate is a metal plate, and a heat dissipation cavity is formed between the heat conducting plate and the thermal insulation sleeve.

[0011] Furthermore, there are a plurality of heat sinks, which are evenly distributed on the inner bottom wall of the circulation bin, and one end of the heat sink located on the inner side of the circulation bin is a heat absorbing end.

[0023] The heat sink 5 includes a pump body 51 with one end fixedly connected to one side of the circulation bin 4, a cooling pipe 55 with one end penetrating and extending to the outside of the reactor 1 is fixedly connected to the inner side, the liquid outlet end of the pump body 51 is connected to a delivery pipe 53 with one end connected to the cooling pipe 55, an insulation sleeve 56 is placed on the outer side of the lower end of the reactor 1, the outer side of the insulation sleeve 56 is connected to a reflux pipe 52 with one end connected to the circulation bin 4, the outer side of the insulation sleeve 56 is connected to a connecting pipe 54 with one end connected to the cooling pipe 55, a heat conducting plate 512 is fixedly installed on the inner side of the insulation sleeve 56, a heat sink 59 is fixedly installed on the inner bottom wall of the circulation bin 4, a support leg 58 is fixedly connected to the lower end of the circulation bin 4, a fan 57 is fixedly installed on the support leg 58, and the ends of the reflux pipe 52, the delivery pipe 53 and the connecting pipe 54 are all fixedly connected with a threaded ring 510.

[0024] In this embodiment, since the reflux pipe 52, the delivery pipe 53 and the connecting pipe 54 can be tightened and fixed on the liquid injection port and the cooling pipe 55 by the threaded ring 510, when the reactor 1 is separated from the entire circulating cooling equipment, it is only necessary to unscrew the threaded ring 510 and take the reactor 1 out of the insulation sleeve 56. Conversely, the reflux pipe 52, the delivery pipe 53 and the connecting pipe 54 are tightened and fixed on the liquid injection port and the cooling pipe 55 by the threaded ring 510, and the entire cooling equipment and the reactor 1 can be assembled to increase the convenience of maintenance and assembly.

[0025] Among them, the insulation sleeve 56 is provided with a liquid injection port on one side close to the return pipe 52 and the connecting pipe 54, and a stopper 511 is fixedly connected to the outer side of the liquid injection port and the end of the cooling pipe 55, and the tightened threaded ring 510 is blocked by the stopper 511.

[0026] In addition, external threads are provided on the outer sides of the liquid injection port and the end of the cooling tube 55 , and the external threads cooperate with the inner wall threads of the threaded ring 510 , so that the rotating threaded ring 510 can be tightened and fixed on the liquid injection port and the end of the cooling tube 55 .

[0027] Secondly, the end of the cooling pipe 55 located inside the reactor 1 is spiral and located outside the stirring shaft 3. The reflux pipe 52, the delivery pipe 53 and the connecting pipe 54 are all soft pipes, which facilitates the assembly and fixation of the reflux pipe 52, the delivery pipe 53 and the connecting pipe 54.

[0028] See also Figure 1 Or 4, in this embodiment, the cross-section of the insulation sleeve 56 is U-shaped, the heat conducting plate 512 is a metal plate, a heat dissipation cavity is formed between the heat conducting plate 512 and the insulation sleeve 56, the number of heat sinks 59 is several, and the several heat sinks 59 are evenly distributed on the inner bottom wall of the circulation bin 4, and the end of the heat sink 59 located on the inner side of the circulation bin 4 is the heat absorption end.

[0029] In this embodiment, since the cooling tube 55 is spirally distributed in the reactor 1, the heat inside the reactor 1 can be evenly dissipated, so the heat sink 59 can dissipate the coolant refluxed into the circulation chamber 4, and the heat conduction plate 512 located in the insulation sleeve 56 can dissipate the heat on the outside of the reactor 1, thereby improving the circulation heat dissipation effect of the reactor 1.

[0030] The working principle of the above embodiment is:

Conversely, the reflux pipe 52, the delivery pipe 53 and the connecting pipe 54 are tightened and fixed on the injection port and the cooling pipe 55 by the threaded ring 510, so that the entire cooling equipment and the reactor 1 can be assembled to increase the convenience of maintenance and assembly. When cooling away from the reaction, since the cooling pipe 55 is spirally distributed in the reactor 1, the heat inside the reactor 1 can be evenly dissipated. Therefore, the heat sink 59 can dissipate the coolant refluxed into the circulation bin 4, and the heat conducting plate 512 located in the insulation sleeve 56 can dissipate the heat on the outside of the reactor 1, thereby improving the circulating heat dissipation effect of the reactor 1.
