[0002] In the process of chemical reaction, the heating and cooling of the reaction kettle is very important. At present, the internal coil is commonly used to circulate hot gas and cold water in the reaction kettle to achieve the purpose of heating and cooling.
[0003] In the traditional design of the reaction kettle, the internal coil is usually made of titanium material. Although titanium material has excellent corrosion resistance, its wear resistance is relatively poor. Therefore, when the base mud in the reaction kettle is stirred and reacted, the internal coil is often worn or even ground, causing the loss of materials in the reaction kettle. In addition, there is another external heating and cooling method, that is, an outer sleeve is arranged outside the kettle body to replace the internal coil. However, this method also has problems because the kettle wall is also often made of titanium material and is prone to breakage. Once the kettle wall is broken, the outer sleeve may block the broken part, making it difficult to be discovered in time, and thus causing the reaction material to flow out with the circulating liquid in the outer sleeve, resulting in further loss of materials.

[0030] The present application will be further described in detail below in combination with all the drawings.
[0031] The present application discloses a reaction kettle heating and cooling device.
[0032] Referring to Figure 1 and Figure 2The utility model relates to a kind of reaction kettle heating and cooling device, including heating kettle 1 and cooling kettle 2.In heating kettle 1, a steam pipe 3 is installed, which is made of corrosion-resistant, wear-resistant stainless steel or titanium pipe.In view of the use environment in heating kettle 1, the material of the steam pipe 3 is particularly selected as stainless steel pipe or titanium pipe, which has good corrosion resistance and high temperature resistance, and can meet the long-term use needs of heating kettle 1.Several gas outlets are evenly arranged on the side wall of the steam pipe 3, and steam is injected into the reaction material in the heating kettle 1 through the gas outlets to achieve rapid and uniform heating effect.
[0033] Referring to Figure 1 And Figure 2 , the specific arrangement of the steam pipe 3 is that the gas inlet end of the steam pipe 3 is located outside the heating kettle 1, which is convenient for external steam source, and the end of the steam pipe 3 away from the gas inlet end is closed to form a closed steam flow path.The part of the steam pipe 3 located in the heating kettle 1 is vertically arranged between the end of the stirring rod 43 away from the shaft 42 and the inner wall of the heating kettle 1, which avoids the interference between the stirring rod 43 and the steam pipe 3, and also ensures that the steam in the steam pipe 3 can be uniformly released into the heating kettle 1 through the gas outlets.
[0034] Referring to Figure 2 , in order to prevent the material in the heating kettle 1 from flowing back into the steam pipe 3 during stirring and heating, a one-way valve 31 is specially arranged at the gas outlet, which only allows steam to flow from the steam pipe 3 into the heating kettle 1, and prevents the material from flowing back into the steam pipe 3.
[0035] Referring to Figure 1 And Figure 2 , the stirring device 4 is also arranged on the heating kettle 1, which can effectively stir the material uniformly to facilitate better heat exchange between steam and material.
[0036] Referring to Figure 1 And Figure 2 , the specific structure of the stirring device 4 includes a motor 41, a shaft 42 and a plurality of stirring rods 43.The motor 41 serves as the driving power source, and its output end is fixedly connected to the upper end of the shaft 42.The motor 41 is fixedly connected to the heating kettle 1 outside the heating kettle 1, and the shaft 42 is rotatably connected to the heating kettle 1 in the vertical direction, so that the motor 41 can drive the shaft 42 to rotate in the heating kettle 1.The stirring rods 43 are distributed along the circumference of the shaft 42 and arranged along the axis of the shaft 42, which can ensure that the stirring rods 43 can stir the material in the heating kettle 1 in all directions and at multiple angles during rotation with the shaft 42.
[0037] In other embodiments, magnetic coupling stirring or the like can also be used to realize the stirring of the material. The magnetic coupling stirring utilizes the action of the magnetic field to enable the stirrer to rotate and stir in the closed container without contact, thereby reducing the mechanical seal and improving the stability and safety of the equipment, and reducing the leakage and wear problems that may occur in the traditional stirring device 4.
[0038] With reference to Figure 1 and Figure 3 , the cooling kettle 2 is provided with a cooling pipe 5, and the cooling medium flowing in the cooling pipe 5 is particularly selected as water. Water has a high specific heat capacity and a high thermal conductivity, and can quickly and effectively cool the material.
[0039] With reference to Figure 1 and Figure 3 , in order to achieve a higher cooling effect, the cooling pipe 5 is specifically arranged in the cooling kettle 2 in a vertical spiral manner. When the cooling medium flows in the pipe, the reaction material is cooled by the cooling effect of the pipe wall. Such an arrangement can increase the contact area between the cooling pipe 5 and the material, thereby improving the cooling efficiency. At the same time, the inlet end and the outlet end of the cooling pipe 5 are located outside the cooling kettle 2, which is convenient for external cooling water source. The outlet end of the cooling pipe 5 is higher than the inlet end in the vertical direction, and such a height difference can ensure that the cooling water can flow smoothly in the cooling pipe 5.
[0040] In other embodiments, horizontal coiled or other shaped pipe designs can also be used to increase the cooling area and improve the cooling efficiency. The horizontally coiled cooling pipe 5 can contact the reaction material to a greater extent, thereby accelerating the cooling speed.
[0041] With reference to Figure 1 , the heating kettle 1 and the cooling kettle 2 are connected with a filtering device 6, which can filter the material during the transfer of the material from the heating kettle 1 to the cooling kettle 2.
[0042] With reference to Figure 1 , the filtering device 6 includes a suction filter 61, a feeding pipe 62 and a discharging pipe 63. One end of the discharging pipe 63 is in communication with the bottom end of the heating kettle 1, and the end of the discharging pipe 63 away from the heating kettle 1 is connected with the suction filter 61. Through the action of the suction filter 61, the reaction completed material is sucked out from the bottom of the heating kettle 1 through the discharging pipe 63, and is separated into solid and liquid through the filtering action of the suction filter 61. One end of the feeding pipe 62 is in communication with the upper end of the cooling kettle 2, and the end of the feeding pipe 62 away from the cooling kettle 2 is connected with the suction filter 61. The filtered liquid material is then conveyed to the cooling kettle 2 through the feeding pipe 62 for cooling treatment.
[0043] In other embodiments, filter pressing, centrifugation or other filtration methods can also be used. Each filtration method has its specific filtration effect and applicable scenario, and can be selected and optimized according to the characteristics of the specific reaction material and the filtration requirements.
[0044] The implementation principle of the reaction kettle heating and cooling device according to the embodiment of the application is as follows: a steam pipe 3 is arranged in the heating kettle 1 to heat the material, the steam pipe 3 is a one-way conveying pipe and always sprays steam outward, so that the material in the heating kettle 1 is prevented from entering the steam pipe 3 and the loss of the material is reduced. At the same time, during the heating process, the material is stirred by the stirring device 4, so that the heating of the material is more uniform. The heated material is filtered by the filtering device 6 to remove impurities, and then enters the cooling kettle 2 for cooling. The cooling kettle 2 does not have a stirring device, so that the cooling pipe 5 is not damaged, the material entering the cooling pipe 5 is reduced, and the loss of the material is reduced. The device realizes the continuous operation of the heating, filtering and cooling of the material, and improves the production efficiency.
[0045] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
