Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a stirring device for a reaction kettle. Background Art

[0002] In a broad sense, a reaction kettle in chemical equipment is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, heating, evaporation, cooling, and mixing functions at low and high speeds required by the process are achieved. During the operation of the reaction kettle, a stirring device that penetrates into its interior is needed to continuously stir and mix the reactants.

[0003] Some existing reaction kettle structures mainly include a reaction kettle body and a stirring device connected to a motor and penetrating into the interior of the kettle body. However, this device that only mixes reactants by stirring has great defects. There are often problems such as incomplete and uneven stirring caused by the stirring structure being unable to reach all parts inside the reaction kettle body. Moreover, due to the different viscosities of liquid reaction materials, some reaction materials are prone to adhering to the inner wall of the reaction kettle body. Especially for a reaction kettle with a heating function at the side wall position, the materials that adhere to the inner wall of the reaction kettle body for a long time are prone to coking. The coking layer also affects the heating effect, resulting in an impact on the stirring effect and mixing effect, and then greatly affecting the quality of chemical production. In addition, during the stirring and reaction process, materials need to be added at any time. The general addition method is to stop the machine and open the lid of the reaction kettle to add materials, or set an injection pipe at the lid. However, this addition method adds materials to the upper surface layer of the materials in the reaction kettle, and it takes a long time to stir to fully mix, which also affects the stirring and mixing efficiency.

[0059] The working process of the present invention will be described below through two embodiments:

[0060] Embodiment 1.

[0061] As Figures 1 to 4 shown, start the motor 21, and the motor 21 drives the rotating shaft 22 to rotate. At this time, on the one hand, the rotating shaft 22 transmits the power to the feeding pipe 41 through the sealing sleeve 52, driving the feeding pipe 41 and the stirring rod 3 communicated with the feeding pipe 41 to rotate. On the other hand, the lower end of the rotating shaft 22 transmits the power to the stirring rod 3 and the scraping mechanism 7 through the first annular plate 81 and the first reinforcing rod 83, and the upper end of the stirring rod 3 transmits the power to the scraping mechanism 7 through the second annular plate 82 and the second reinforcing rod 84, so that the stirring rod 3 and the scraping mechanism 7 rotate with the rotation of the rotating shaft 22. The continuous rotation of the stirring rod 3 can stir the materials in the reaction kettle tank body 1;

[0062] During the process of the stirring rod 3 stirring the materials in the reaction kettle tank body 1, if the stirring speed is relatively low, the centrifugal force of the blocking mechanism 6 is relatively small, and the swing sealing plate 61 will not drive the sealing plug 62 to block the discharge port 31. At this time, the materials to be added can be injected into the feeding pipe 41 from the feed port 42 as needed, then flow into the inside of the stirring rod 3 along the feeding pipe 41, and finally be injected into the reaction kettle tank body 1 from the discharge port 31 and be stirred with the materials in the reaction kettle tank body 1 by the stirring rod 3, improving the stirring efficiency, as Figure 1 shown; if the stirring speed is relatively high, the centrifugal force of the blocking mechanism 6 is relatively large, and the swing sealing plate 61 will drive the sealing plug 62 to block the discharge port 31. At this time, it is impossible to continue adding external materials, as Figure 3 shown;

[0063] During the process of the stirring rod 3 stirring the materials in the reaction kettle tank body 1, the rubber scraping strip 72 is also rotating continuously, scraping the inner wall of the reaction kettle tank body 1, and the scraped materials flow out from the material flow hole 73 into the reaction kettle tank body 1 and continue to participate in the stirring, ensuring good stirring effect and mixing efficiency, and effectively improving the quality of chemical production;

[0064] During the process of the stirring rod 3 stirring the materials in the reaction kettle tank body 1, external high-temperature steam enters the annular space formed by enclosing the reaction kettle tank body 1 and the jacket 9 through the steam inlet 91, heats the materials in the reaction kettle tank body 1, and discharges from the steam outlet 92, thereby continuously heating the materials in the reaction kettle tank body 1.

[0065] Embodiment 2.

[0066] AsFigure 5 and Figure 6 As shown in and

[0067] , in this embodiment, except that the structure and working method of the scraping mechanism 7 are different from those in the first embodiment, the other working processes are the same as those in the first embodiment and will not be described herein again.

[0067] In this embodiment, during the process of the stirring rod 3 stirring the materials in the reaction kettle body 1, since the diversion scraper 75 abuts against the inner wall of the reaction kettle body 1 and the diversion scraper 75 is hinged to the support frame body 74, the diversion scraper 75 will be inclined when rotating with respect to the inner wall of the reaction kettle body 1. One end of the diversion scraper 75 away from the inner wall of the reaction kettle body 1 will exert a thrust on the arc-shaped elastic piece 76. The arc-shaped elastic piece 76 deforms to generate a resilience force. Under the action of this resilience force, the diversion scraper 75 is continuously abutted against the inner wall of the reaction kettle body 1, and the materials on the inner wall of the reaction kettle body 1 are scraped during the continuous rotation of the diversion scraper 75. Moreover, the scraped materials will enter the reaction kettle body 1 again through the space between the diversion scraper 75 and the support frame body 74 to participate in the stirring.
