Description

Technical Field

[0001] The present application relates to the technical field of chemical equipment, and in particular to a reaction kettle for producing a PVC anti-sticking kettle agent. Background Art

[0002] The main part of the reactor is usually cylindrical or spherical, made of high-strength metal materials (such as stainless steel, carbon steel, etc.), and can withstand certain pressure and temperature. During the use of the reactor, PVC anti-sticking agent plays a vital role. It can form a protective film on the inner wall of the reactor, effectively preventing PVC polymer from adhering to the reactor wall under high temperature and high pressure reaction conditions. This not only ensures the smooth progress of the reaction, reduces the frequency of production interruptions and equipment cleaning caused by sticking, but also improves the service life and production efficiency of the reactor.

[0003] However, in the process of processing PVC anti-sticking agent in the existing reactor, it is difficult to scrape off the products adhered to the outer wall of the stirring rod when the stirring rod is rotating, which will cause a large amount of products to adhere to the stirring rod, resulting in product waste, while increasing the difficulty and workload of the staff in the later cleaning, reducing production efficiency, and at the same time, during the long-term rotation of the stirring rod, the more products adhere to the outer wall of the stirring rod, the more likely it is that the fluid resistance encountered by the stirring rod during rotation will increase, thereby affecting the smoothness and stability of the rotation of the stirring rod, which may lead to poor stirring effect.

[0004] At the same time, in the process of processing PVC anti-sticking agent in existing reactors, most of the stirring rods are welded and fixed, and can usually only be stirred at a fixed position and angle, which is easy to form a stirring dead angle, resulting in uneven material mixing. At the same time, there is a lack of centralized stirring function, which cannot effectively deal with the phenomenon of local uneven concentration, and is prone to uneven stirring. At the same time, the traditional stirring method may not be able to continuously break the laminar flow state in the solution. The traditional stirring rod can only form a relatively stable stirring flow field at a specific position. The fluid in the solution is easy to form a laminar flow in this case, that is, the layers of the fluid flow relatively parallel. This flow mode makes the material exchange between different layers relatively less, so that the solutions at different levels are not fully mixed, the mixing uniformity is poor, and the solution cannot always be in dynamic change, affecting the reaction rate and product quality. Summary of the invention

[0005] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a reactor for producing PVC anti-sticking kettle agent, wherein the reactor for producing PVC anti-sticking kettle agent enables the auxiliary stirring rod to circulate and retract in the main stirring rod, and when extended, the stirring range is expanded and the stirring quality is improved, and when shortened, the stirring is concentrated and the local concentration unevenness is reduced, and at the same time, the laminar flow state of the solution is broken to improve the mixing uniformity, and at the same time, the products adhered to the outer wall of the main and auxiliary stirring rods are scraped off to reduce waste and facilitate later cleaning, while keeping the stirring rod clean, stabilizing the fluid resistance, and ensuring smooth and stable rotation. At the same time, the anti-blocking scraping mechanism can stir the products at the bottom of the reaction barrel at different depths to reduce deposition, and can also scrape the outer wall of the stirring tube to reduce product waste.

At this time, the auxiliary stirring rod 314 begins to move toward the inner wall of the main stirring rod 311 under the action of the sliding plate 312. The main stirring rod 311 is used for the auxiliary stirring rod 314 to be scraped, and the cleaning rack 316 starts to scrape the outer wall of the main stirring rod 311 again, thereby achieving the purpose of multiple cycles of scraping. At the same time, the main stirring rod 311 and the auxiliary stirring rod 314 also start to continuously stir the product inside the reaction barrel 101 under the action of the stirring tube 204. Since the auxiliary stirring rod 314 continuously retracts and retracts inside the main stirring rod 311, the function of dynamic stirring is achieved. When the auxiliary stirring rod 314 is extended, the stirring range can be increased, so that the product in the corner can also be fully stirred, thereby improving the stirring quality of the product. When the auxiliary stirring rod 314 is shortened, it can play a centralized stirring function, thereby reducing the occurrence of local concentration unevenness. At the same time, the cyclic shortening and lengthening action can continuously break the laminar state in the solution, promote the full mixing of solutions at different levels, and the retractable stirring rod continuously changes its position, so that the solution is always in a dynamic change, thereby improving the uniformity of mixing.

[0051] like Fig.10 and Fig.11As shown, the anti-blocking scraping mechanism 4 includes a fixed plate 401 and a scraping ring 406. The fixed plate 401 is fixedly connected to the outer wall of the front end of the reciprocating slider 303. The lower end of the fixed plate 401 penetrates the stirring tube 204 and is fixedly connected to a fixed frame 402. The lower end of the fixed frame 402 is fixedly connected to a cross stirring frame 404. The front end and the rear end of the upper surface of the cross stirring frame 404 are respectively fixedly connected to a connecting rod 405. A plurality of scraping rings 406 are fixedly connected to the outer wall of the connecting rod 405. The scraping ring 406 scrapes reciprocatingly up and down on the outer wall of the stirring tube 204. A guide short rod 403 is fixedly connected to one side of the upper surface of the fixed frame 402. The guide short rod 403 penetrates the stirring tube 204 and extends to the inside of the stirring tube 204. During the production of PVC anti-sticking agent, the stirring tube 204 is rotated by starting the servo motor 201, at which time the rotating rod 301 will also rotate, and the reciprocating slider 303 will also drive the fixed plate 401 to move up and down. At the same time, the cross stirring frame 404 starts to move up and down at the bottom of the reaction barrel 101 under the action of the fixed frame 402, and the cross stirring frame 404 will also rotate while moving up and down, thereby effectively reducing the uneven mixing of the products at the bottom of the reaction barrel 101. At the same time, during the up and down movement of the fixed frame 402, the connecting rod 405 will also drive the scraping ring 406 to continuously scrape the outer wall of the stirring tube 204 up and down, thereby further reducing the phenomenon of product adhesion on the surface of the stirring tube 204. In the embodiment, the servo motor 201 is started to rotate the stirring tube 204. Firstly, the auxiliary stirring rod 314 can be continuously extended and retracted in a circular manner inside the main stirring rod 311. When the auxiliary stirring rod 314 is extended, the stirring range can be increased, so that the products in the corners can also be fully stirred, thereby improving the stirring quality of the products. When the auxiliary stirring rod 314 is shortened, it can play a centralized stirring function, thereby reducing the occurrence of local concentration unevenness. Secondly, the cyclic shortening and lengthening action can continuously break the laminar flow state in the solution and promote the full mixing of solutions at different levels. The retractable stirring rod continuously changes its position, so that the solution is always in a dynamic change, thereby improving the uniformity of mixing. Thirdly, the auxiliary stirring rod 314 During the extension and retraction stirring process of the main stirring rod 311, the products adhering to the outer walls of the main stirring rod 311 and the auxiliary stirring rod 314 can also be hung down, thereby reducing the waste of products and bringing convenience to the staff's subsequent cleaning work. Fourthly, in the stirring process, the products adhering to the surface of the stirring rod can be scraped off in time to keep the stirring rod clean, thereby stabilizing the fluid resistance encountered during its rotation, and effectively ensuring the smoothness and stability of the stirring rod during rotation. Fifthly, the anti-blocking scraping wall mechanism 4 can also stir the product at the bottom of the reaction barrel 101 at different depths, thereby reducing the phenomenon of product deposition. At the same time, the outer wall of the stirring tube 204 can also be scraped to further reduce the waste of products.

[0052] Specifically, the working principle of the reactor for producing PVC anti-sticking agent is as follows: Specifically, in the process of producing PVC anti-sticking agent, the stirring tube 204 can be rotated by starting the servo motor 201, and the rotating rod 301 will rotate synchronously with the stirring tube 204, and then the rotating rod 301 can drive the reciprocating threaded sleeve 302 to rotate under the mutual meshing of the driven gear plate 322 and the inner gear ring 323, and the reciprocating slider 303 starts to move downward from the top of the reciprocating threaded sleeve 302, so that the tooth plate 305 and the gear 308 are meshed with each other, and the capstan 307 rotates clockwise, and the right end of the traction rope 309 starts to be released from the outer wall of the capstan 307 under the clockwise rotation of the capstan 307. At this time, the traction rope 309 in the release process begins to be released from the outer wall of the capstan 307. 9 The traction force on the sliding plate 312 is reduced, and the reset length is provided for the reset spring 313. At this time, under the action of the reset spring 313, the sliding plate 312 begins to drive the auxiliary stirring rod 314 to slide inside the main stirring rod 311. At the same time, the connecting circular plate 315 drives the cleaning frame 316 to scrape the outer wall of the main stirring rod 311. At the same time, the left end of the traction rope 309 begins to be wound around the outer wall of the capstan 307 under the clockwise rotation of the capstan 307. At this time, the left end of the traction rope 309 begins to pull the sliding plate 312 and make the sliding plate 312 slide inside the main stirring rod 311. At this time, the auxiliary stirring rod 314 begins to slide towards the inside of the main stirring rod 311 under the action of the sliding plate 312. At this time, the outer wall of the auxiliary stirring rod 314 is scraped by the main stirring rod 311. The cleaning rack 316 starts to scrape the outer wall of the main stirring rod 311 again, thereby achieving the purpose of multiple cycles of scraping. At the same time, the main stirring rod 311 and the auxiliary stirring rod 314 also start to continuously stir the product inside the reaction barrel 101 under the action of the stirring tube 204. Since the auxiliary stirring rod 314 continuously retracts and retracts inside the main stirring rod 311, the function of dynamic stirring is achieved. When the auxiliary stirring rod 314 is extended, the stirring range can be increased, so that the product in the corner can also be fully stirred, thereby improving the stirring quality of the product. When the auxiliary stirring rod 314 is shortened, it can play a centralized stirring function, thereby reducing the occurrence of local concentration unevenness. At the same time, the cyclic shortening and lengthening action can continuously break the laminar state in the solution and promote Solutions at different levels are fully mixed, and the retractable stirring rod keeps changing its position, so that the solution is always in dynamic change, thereby improving the uniformity of mixing. At the same time, the servo motor 201 is started to rotate the stirring tube 204, and the rotating rod 301 will also rotate, and the reciprocating slider 303 will also drive the fixed plate 401 to move up and down. At the same time, under the action of the fixed frame 402, the cross stirring frame 404 begins to move up and down at the bottom of the reaction barrel 101, and the cross stirring frame 404 will also rotate while moving up and down, thereby effectively reducing the phenomenon of uneven mixing of products at the bottom of the reaction barrel 101. At the same time, in the process of the fixed frame 402 moving up and down, the connecting rod 405 will also drive the scraper ring 406 to scrape the outer wall of the stirring tube 204 up and down.This further reduces the occurrence of product adhesion on the surface of the stirring tube 204.
