Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction kettle devices, and specifically, to an automatic temperature control device for a reaction kettle. Background Art

[0002] The reactions of chemical products are divided into endothermic reactions and exothermic reactions. Too high or too low temperature directly affects the speed of chemical reactions, and thus affects the reaction rate. Moreover, too high or too low temperature will produce various by-products, affecting the purity of the final product. Generally speaking, a reaction kettle is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized.

[0003] In the existing publicly known technology, the publication number is: CN219051298U, an automatic temperature control device for a reaction kettle. The automatic temperature control device for the reaction kettle includes a reaction kettle. A stirring device is arranged inside the reaction kettle. A circulation pipeline is arranged inside the reaction kettle. A hot water pipe is arranged on one side of the reaction kettle. A condensate pipe is arranged on the other side of the reaction kettle. A circulation device is arranged on the circulation pipe. A driving device for driving the stirring device to move is arranged on the reaction kettle; materials are brought into the reaction kettle through the feed inlet. The motor drives the stirring shaft to rotate. The stirring shaft drives the slide plate to rotate. The slide plate drives the stirring rod to rotate. The reciprocating thread can drive the slide plate to move up and down reciprocally. The slide plate is limited by the slider and the chute to move on the stirring shaft, fully reacting the materials, accelerating the reaction rate, and reducing the production time.

[0004] However, the above patent still has certain disadvantages in use: its temperature can be adjusted for the reaction kettle through the circulation pipe, and the temperature control structure is single. Moreover, the temperature transmitted through the circulation pipe moves from the outside to the inside of the reaction kettle, which easily causes a large difference between the temperature on the outside and the temperature at the center position of the kettle body, thereby affecting the overall temperature control effect. And the one-way temperature transmission will not only prolong the overall temperature control time, reduce the temperature control efficiency, but also make the temperature inside the kettle body uneven, thereby affecting the reaction efficiency and quality of the internal substances. The overall use effect is not very ideal.

[0005] In view of the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

As Figures 1-4 shown, an automatic temperature control device for a reaction kettle according to an embodiment of the present utility model includes a reaction kettle main body 1 and support legs 11. In the middle position at the top end inside the reaction kettle main body 1, a driving shaft 18 is rotatably connected. In the middle position inside the driving shaft 18, a temperature control pipe 20 is provided. On the surface of the driving shaft 18, a number of groups of temperature control disks 2 are symmetrically installed. The inside of the temperature control disk 2 is a hollow structure, and in the middle position, a number of groups of temperature control strips 3 are provided. One end of the temperature control strip 3 is connected to the temperature control pipe 20. The inside of the temperature control pipe 20 is divided into an introduction chamber 8 and an outlet chamber 10 by a partition plate 15. On the surface where the temperature control strip 3 contacts the temperature control pipe 20, a water inlet pipe 6 and a water outlet pipe 7 are respectively installed. The water inlet pipe 6 and the water outlet pipe 7 are respectively connected to the introduction chamber 8 and the outlet chamber 10. Inside the temperature control strip 3, a number of groups of extension plates 4 are evenly and staggeredly installed, and a flow chamber 5 is provided between two adjacent extension plates 4. Around the inside of the surface of the reaction kettle main body 1, a circulation pipe 14 is installed. At the top end inside the reaction kettle main body 1, a temperature sensor 16 is fixedly installed. The temperature sensor 16 is provided to detect the temperature inside the reaction kettle for subsequent corresponding temperature control operations.

[0031] In one embodiment, at the bottom position on one side surface of the reaction kettle main body 1, a circulation water tank 12 is fixedly installed. Inside the circulation water tank 12, a heater and a cooler are provided. At the top position of the circulation water tank 12, a water pump 13 is installed, and the water pump 13 is respectively connected to the circulation pipe 14 and the temperature control pipe 20 through pipelines. The water pump 13 is provided to enable the water source inside the circulation water tank 12 to be recycled.

[0032] In one embodiment, an introduction pipe 21 and an outlet pipe 19 are respectively installed on both sides at the top of the temperature control pipe 20. The introduction pipe 21 is connected to the water pump 13, and the outlet pipe 19 is connected to the circulation water tank 12. The circulation water tank 12 is a common liquid circulation structure, and it is only used here without modification, so it will not be elaborated too much.

[0033] In one embodiment, the outer peripheral position at the top of the drive shaft 18 is connected to the drive mechanism 17, which is composed of a motor, a transmission wheel, and a transmission belt. The transmission wheel is located on the surfaces of the motor and the drive shaft 18, and a transmission belt is provided therebetween. The drive mechanism 17 is provided to drive the drive shaft 18 to rotate.

[0034] In one embodiment, a feed inlet 23 is fixedly installed at one side position at the top of the reactor main body 1. The setting of the feed inlet 23 facilitates the addition of the raw materials to be processed.

[0035] In one embodiment, support legs 11 are symmetrically installed on the surfaces at both sides of the bottom of the reactor main body 1. The device as a whole can be fixed through the support legs 11, which is convenient for enhancing the overall use stability.

[0036] In one embodiment, a discharge port 9 is fixedly installed at the middle position of the bottom of the reactor main body 1. The discharge port 9 is provided to discharge the substances inside the reactor after the operation is completed.

[0038] Working principle: In the actual use process, personnel can add the raw materials to be reacted through the feed inlet 23, and then add corresponding warm water or cold water to the internal of the circulation water tank 12 according to the different types of endothermic and exothermic reactions, and turn on the internal cooler or heater to maintain the water temperature after subsequent circulation, ensuring the temperature inside the reactor main body 1, so as to improve the overall reaction temperature suitability. When the water body circulates, first, the corresponding water can be introduced through the inlet pipe 21. At this time, the introduced water will move along the inlet cavity 8 and enter through the water inlet pipe 6 on the surface of the temperature control strip 3, and then continuously flow along the flow cavity 5 inside the temperature control strip 3. Since the flow cavity 5 is a structure with multiple bends, the retention time of the water can be extended, and thus better heat absorption or heat release treatment can be carried out. Then, the used water will enter the export cavity 10 through the outlet pipe 7, and then flow along the export cavity 10 to the outlet pipe 19 and finally enter the circulation water tank 12 for circulation treatment. Moreover, while adjusting the temperature inside the reactor main body 1, the corresponding water body circulation can also be carried out through the circulation pipe 14 on the outer surface, so that the overall temperature can be synchronized inside and outside, thereby improving the temperature adjustment effect and avoiding large temperature differences inside and outside caused by single-sided temperature adjustment, which affects the temperature adjustment effect and the reaction efficiency of substances. The device as a whole has the advantages of multiple temperature adjustments, good temperature adjustment effect, and uniform temperature.
