Abstract
Description
Technical Field
[0001] This utility model relates to the field of acrylic resin processing technology, and in particular to a production mixing tank. Background Technology
[0002] Acrylic resin, as a general term for polymer systems of acrylic acid, methacrylic acid and their derivatives, is an indispensable high-molecular functional material in modern industry. It is widely used in coatings, adhesives, inks and special functional coatings. In its production and processing, the stirred tank is not only the core equipment for achieving efficient mixing of monomers with initiators, solvents and other components, but also the key reaction vessel for the polymerization reaction.
[0003] Most existing production mixing tanks adopt a single circumferential stirring mode. In the high viscosity state of the later stage of acrylic resin polymerization, the material is prone to stratification and mixing dead zones, resulting in low mixing efficiency. This makes it difficult to ensure the mixing of materials in the upper and lower areas of the tank, which in turn easily causes local uneven concentration and affects the quality stability of acrylic resin.
[0004] Therefore, those skilled in the art have provided a production stirred tank to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a production mixing vessel. Through the rollers and chute in the mixing mechanism, the connecting shaft can also reciprocate up and down while rotating, thereby achieving multi-dimensional mixing, which not only improves mixing efficiency but also shortens the reaction cycle.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A production mixing tank includes a tank body, an internal stirring mechanism is provided inside the tank body, the stirring mechanism includes a motor and a connecting shaft, a rotating shaft is fixedly provided at the output end of the motor, a plurality of fixing blocks are fixedly connected to the outer wall of the rotating shaft, and a sliding groove is provided on the upper end of the inner wall of the tank body.
[0008] The upper end of the connecting shaft is provided with a connecting groove, and two connecting rods are fixedly provided on the upper outer side of the connecting shaft. Rotating blocks are rotatably provided on opposite sides of the two connecting rods, and rollers are rotatably provided on opposite sides of the two rotating blocks.
[0009] Furthermore, the lower end of the motor is fixedly mounted on the upper end of the vessel body, and the plurality of fixing blocks and the outside of the rotating shaft are slidably mounted inside the connecting groove.
[0010] Furthermore, both rollers are externally disposed inside the slide groove, and both connecting rods have rotating plates rotatably disposed at their lower ends.
[0011] Furthermore, multiple stirring blades are fixedly installed on the outside of the connecting shaft, and multiple scrapers are fixedly installed on the lower part of the outside of the connecting shaft.
[0012] Furthermore, the scrapers and stirring blades are all externally disposed inside the lower part of the vessel body, and the two rotating blocks are both externally slidably disposed inside the chute.
[0013] Furthermore, a discharge pipe is fixedly provided at the lower end of the vessel body, and the upper end of the discharge pipe is located at the lower end of the connecting shaft.
[0014] Furthermore, a control panel is fixedly installed at the front end of the vessel body, and multiple support legs are fixedly installed at the lower end of the vessel body.
[0015] This utility model has the following beneficial effects:
[0016] This invention proposes a production mixing vessel. When processing acrylic resin inside the vessel, the motor is started, causing the rotating shaft to drive the fixed block to rotate, which in turn causes the connecting shaft to rotate synchronously. This, in turn, causes the stirring blades and scrapers to rotate synchronously inside the vessel, achieving material stirring. The connecting rod also drives the rotating block to rotate, causing the rollers to move inside the chute. The chute is not only symmetrically designed but also has an undulating state, so that when the connecting shaft rotates, the rollers will slide up and down on the outside of the rotating shaft, thereby achieving multi-dimensional stirring of the acrylic resin. This not only improves mixing efficiency but also helps to shorten the production cycle of acrylic resin, thereby improving overall production efficiency and ensuring stable and reliable processing quality.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figures 1-5 One embodiment provided by this utility model:
[0026] A production mixing tank includes a tank body 1, a stirring mechanism 4 is provided inside the tank body 1, the stirring mechanism 4 includes a motor 401 and a connecting shaft 407, a rotating shaft 404 is fixedly provided at the output end of the motor 401, a plurality of fixing blocks 409 are fixedly connected to the outer wall of the rotating shaft 404, and a sliding groove 405 is provided on the upper end of the inner wall of the tank body 1.
[0027] A connecting groove 410 is provided at the upper end of the connecting shaft 407. Two connecting rods 403 are fixedly provided at the upper outer end of the connecting shaft 407. Rotating blocks 411 are rotatably provided on opposite sides of the two connecting rods 403. Rollers 402 are rotatably provided on opposite sides of the two rotating blocks 411.
[0028] The lower end of the motor 401 is fixedly mounted on the upper end of the vessel body 1. Multiple fixing blocks 409 and rotating shaft 404 are slidably mounted inside the connecting groove 410. The two rollers 402 are both mounted inside the sliding groove 405. Rotating blades 412 are rotatably mounted on the lower ends of the two connecting rods 403. Multiple stirring blades 406 are fixedly mounted on the outside of the connecting shaft 407. Multiple scrapers 408 are fixedly mounted on the lower end of the outside of the connecting shaft 407. The multiple scrapers 408 and multiple stirring blades 406 are both mounted on the lower end of the vessel body 1. The two rotating blocks 411 are slidably mounted inside the sliding groove 405. A discharge pipe 5 is fixedly mounted on the lower end of the vessel body 1. The upper end of the discharge pipe 5 is mounted on the lower end of the connecting shaft 407. A control panel 2 is fixedly mounted on the front end of the vessel body 1. Multiple support legs 3 are fixedly mounted on the lower end of the vessel body 1.
[0029] Specifically, in the acrylic resin production process, the mixing vessel is first connected to the power supply. The vessel body 1 is a mature and publicly available technology, therefore, its specific structure and working principle will not be described in detail here. Then, the production material is fed in through the feed port at the top of the vessel body 1. The material feeding amount and the operating parameters of the stirring mechanism 4 have been optimized to ensure that the liquid level of the material in the vessel is always kept within a safe range below the lowest position of the chute 405. This effectively prevents the material from entering the chute 405 and prevents the roller 402 from jamming or the chute 405 from wearing due to material accumulation. At the same time, it ensures that the stirring blades 406 and scrapers 408 work efficiently in the material layer and maintain stable mixing. Regarding the effect and equipment lifespan, the operator only needs to press the start button on the control panel 2, and the motor 401 will start to run smoothly at the top of the vessel 1. Connecting the power supply and starting through the control panel 2 are both existing mature technologies, and their specific structure and working principle will not be described in detail. When the motor 401 is running, the rotating shaft 404 at its output end will drive the fixed block 409 to rotate together. Since the rotating shaft 404 and the fixed block 409 are slidably connected to the connecting groove 410, the connecting shaft 407 can rotate synchronously inside the vessel 1, thereby driving the stirring blades 406 and scraper 408 on the connecting shaft 407 to rotate accordingly, and fully stirring the acrylic resin in the vessel.
[0030] While the connecting shaft 407 rotates, the connecting rod 403 connected to it also rotates synchronously inside the vessel body 1. The rotating plate 412 at its lower end will follow the connecting rod 403 and move inside the vessel body 1. As the connecting rod 403 rotates, the rotating block 411 also moves accordingly. Since the roller 402 is embedded in the groove 405 on the inner wall of the vessel body 1, and the groove 405 is symmetrically distributed and has an undulating structure, when the connecting shaft 407 rotates, the roller 402 will continuously roll in the groove 405. The rolling process of the roller 402, through the rotating block 411, causes the connecting rod 403 to drive the connecting shaft 407 to move up and down reciprocally inside the vessel body 1. At this time, the connecting groove 410 at the upper end of the connecting shaft 407 will slide up and down reciprocally outside the rotating shaft 404 and the fixed block 409, and drive the stirring blade 406 to move synchronously, thereby fully covering the upper and lower areas of the vessel body 1 and forming a three-dimensional stirring flow field. Compared with the traditional stirring method, This effectively improves mixing efficiency and avoids quality defects caused by uneven mixing of acrylic resin, ensuring stable product performance. Even during the polymerization process where the viscosity of acrylic resin varies greatly, it ensures thorough mixing of materials, providing a guarantee for high-quality production. After the polymerization reaction is completed, the valve on the discharge pipe 5 is opened, and the acrylic resin product in the reactor 1 is discharged through the discharge pipe 5. The support leg 3 provides stability to the reactor 1. The symmetrical undulating structure of the chute 405 and the rolling cooperation of the roller 402 not only make the stirring efficiency high, but also reduce the friction loss between parts, extend the service life of the equipment, and reduce maintenance costs and downtime. The surface of the roller 402 is made of wear-resistant rubber, and the inner wall of the chute 405 is provided with a fixing groove, which facilitates the injection of lubricating oil through the fixing groove in the later stage, thereby reducing friction loss. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0031] Working principle: When processing acrylic resin, first connect the mixing tank to the power supply. Then, feed the material into the tank body 1 through the feed port at the top. Next, start the motor 401 through the control panel 2 to make it rotate at the top of the tank body 1. The rotation of the motor 401 will drive the rotating shaft 404 at its output end to rotate the fixed block 409. Since the rotating shaft 404 and the fixed block 409 are slidably connected to the connecting groove 410, the rotation of the rotating shaft 404 will drive the connecting shaft 407 to rotate synchronously inside the tank body 1. This will cause the stirring blades 406 and scraper 408 on the connecting shaft 407 to rotate as well. The rotation of the two will stir the acrylic resin inside the tank body 1.
[0032] While the connecting shaft 407 rotates, it drives the connecting rod 403 to rotate synchronously inside the vessel body 1. The rotation of the connecting rod 403 causes the rotating block 411 to move, which in turn drives the rotating blade 412 at its lower end to move inside the vessel body 1. Since the roller 402 is set in the groove 405 on the inner wall of the vessel body 1, the roller 402 will roll inside the groove 405 when the connecting shaft 407 rotates. The groove 405 is symmetrically designed and has an undulating state. The rolling of the roller 402 will cause the connecting rod 403 to move up and down inside the vessel body 1 through the rotating block 411. This allows the connecting shaft 407 to slide outside the rotating shaft 404 and the fixed block 409 through the connecting groove 410. This allows the stirring blade 406 to move up and down while rotating, which not only achieves the circumferential mixing of traditional stirring, but also covers the upper and lower areas of the vessel body 1, improving the mixing efficiency.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
