[0027] In one embodiment, as Figures 1 - 3As shown in the figure, a temperature-controlled stirring device for chemical industry includes a reaction kettle 100, a cooling chamber 200, a heating chamber 300 and a stirring assembly. The cooling chamber 200 is sleeved on the outer wall of the reaction kettle 100. The heating chamber 300 is fixedly connected to the bottom of the reaction kettle 100. The stirring assembly includes a support frame 401. The support frame 401 is fixedly connected to the top of the reaction kettle 100. A motor 402 is fixedly connected to the inner top wall of the support frame 401. The output end of the motor 402 is fixedly connected to a first synchronous pulley 403. A second synchronous pulley 404 is also provided at the top of the reaction kettle 100. A belt is provided between the first synchronous pulley 403 and the second synchronous pulley 404. Stirring rods 405 are fixedly connected to the bottoms of both the first synchronous pulley 403 and the second synchronous pulley 404. A scraper 406 is fixedly connected to one side of the stirring rod 405. By starting the motor 402, the first synchronous pulley 403 and the second synchronous pulley 404 are driven to rotate, thereby driving the stirring rod 405 to rotate. The stirring rod 405 drives the scraper 406 to slide on the inner wall of the kettle, scraping the mixture on the inner wall of the kettle to prevent the mixture from sticking to the inner wall of the kettle.

[0028] In one embodiment, as Figure 3 shown, the cleaning assembly includes a shunt pipe 501. One end of the shunt pipe 501 penetrates the reaction kettle 100, and the part of the shunt pipe 501 exposed outside the reaction kettle 100 can be externally connected to a water source. One side of the shunt pipe 501 is fixedly connected to the inner top wall of the reaction kettle 100. A plurality of spray heads 502 are communicated with the other side of the shunt pipe 501. By externally connecting a water source to the shunt pipe 501, the water source is shunted through the shunt pipe 501 into the spray heads 502, and then the water is sprayed into the reaction kettle 100 by the spray heads 502 to clean the inside of the kettle.

[0029] In one embodiment, as Figure 2 shown, a liquid inlet 601 is provided at the top of the cooling chamber 200, and a liquid outlet 602 is provided at the bottom of the cooling chamber 200. Both the liquid inlet 601 and the liquid outlet 602 can be externally connected to a circulation system. By externally connecting a circulation system to the liquid inlet 601 and the liquid outlet 602, and putting the cooled liquid into the cooling chamber 200 through the liquid inlet 601 by the circulation system, heat exchange is carried out between the cooling chamber 200 and the reaction kettle 100. When the heat exchange is completed, the liquid is discharged from the liquid outlet 602 and re-enters the circulation system to avoid wasting water resources.

[0030] In one embodiment, as Figure 1 and Figure 2As shown, a feed inlet is provided at the top of the reactor 100, and a top cover 701 is provided on the feed inlet. An outlet 702 is provided at the bottom of the reactor 100, and the outlet 702 penetrates through the heating chamber 300. A solenoid valve 703 is provided on the part of the outlet 702 exposed from the heating chamber 300. Materials are put into the reactor 100 through the feed inlet, and after all the materials are put in, the top cover 701 is covered on the feed inlet to avoid heat loss inside the reactor 100. After stirring is completed, by opening the solenoid valve 703, the materials can be discharged from the outlet 702.

[0031] In one embodiment, as Figure 2 shown, an electric heating tube 801 is provided on the inner bottom wall of the heating chamber 300, and support feet 802 are provided at the bottom of the heating chamber 300. By turning on the electric heating tube 801, heat is transferred into the reactor 100, and the equipment is supported by the support feet 802.

[0032] In one embodiment, as Figure 1 shown, a controller 901 is provided at the top of the reactor 100, and a first temperature sensor 902 is also provided at the top of the reactor 100. Second temperature sensors 903 are provided in the middle and the middle-lower part of the side wall of the reactor 100. Through the first temperature sensor 902 and the second temperature sensors 903, the temperatures of the upper, middle, and lower parts of the reactor 100 can be accurately monitored in real time.

[0033] In one embodiment, as Figure 2 and Figure 3 shown, the stirring rod 405 is in a cross shape. With the cross-shaped stirring rod 405, the stirring range at the bottom can be enlarged and the stirring range at the top can be reduced to ensure that there is no mixture deposition at the bottom.

[0034] The above embodiments disclose a temperature-controlled stirring device for chemical industry. Firstly, materials are put into the interior of the reaction kettle 100 through the feed inlet. After the input is completed, the top cover 701 is covered on the feed inlet to avoid heat loss inside the reaction kettle 100. Subsequently, the electric heating tube 801 is turned on to raise the temperature inside the reaction kettle 100. At this time, the motor 402 is turned on to drive the first synchronous wheel 403 and the second synchronous wheel 404 to rotate, thereby driving the stirring rod 405 to rotate. The stirring rod 405 drives the scraper 406 to slide on the inner wall of the kettle body to scrape off the mixture on the inner wall of the kettle body and prevent the mixture from adhering to the inner wall of the kettle body. When the first temperature sensor 902 and the second temperature sensor 903 detect in real time that the temperature inside the reaction kettle 100 is higher than the preset value, an external circulation system is connected at this time, and the cooled liquid is put into the cooling chamber 200 through the liquid inlet 601, and heat exchange is carried out between the cooling chamber 200 and the reaction kettle 100. After the heat exchange is completed, the liquid is discharged from the liquid outlet 602 and re-enters the circulation system. After the stirring is completed, by opening the solenoid valve 703, the materials can be discharged from the discharge port 702. Subsequently, the interior of the reaction kettle 100 needs to be cleaned. By connecting an external water source and diverting the water source through the shunt pipe 501 into the spray head 502, and then the spray head 502 sprays water into the interior of the reaction kettle 100. At the same time, the motor 402 can also be turned on to make the scraper 406 slide on the inner wall of the kettle body to cooperate with the spray head 502 to clean the interior of the kettle body.
