Description

Technical Field

[0001] The utility model relates to the technical field of dispersants, in particular to a preparation device for an environment-friendly dispersant. Background Art

[0002] A dispersant is an interfacial active agent that simultaneously has two opposite properties of lipophilicity and hydrophilicity within a molecule. It can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in a liquid, and at the same time can also prevent the sedimentation and aggregation of particles, and is an amphiphilic reagent required to form a stable suspension.

[0003] In the existing dispersant preparation device, the scraper often rotates at a high speed synchronously with the stirring paddle to prevent the raw materials from adhering to the inner surface wall. However, the rapid rotation of the scraper on the inner surface wall not only exacerbates the wear of the inner surface wall of the device, shortens the service life of the equipment, but also exacerbates the wear of the scraper itself. In addition, the rapidly rotating scraper also causes relatively large vibrations, which not only affect the stability of the preparation process, but may also have an adverse impact on the preparation quality. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above equipment is in use, due to the high-speed rotation of the scraper and the stirring paddle together, the wear of the equipment is exacerbated and relatively large vibrations are generated, and thus a preparation device for an environment-friendly dispersant is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A preparation device for an environment-friendly dispersant, including a reaction tank, the top of the reaction tank is fixedly communicated with an air outlet valve, the top of the reaction tank is fixedly communicated with a feed inlet, a shaft hole is opened at the top of the reaction tank, a controller is arranged at the top of the reaction tank, the bottom of the reaction tank is fixedly communicated with a discharge outlet, a fixed rod is fixedly installed on the inner wall top of the reaction tank, and a first gear is movably sleeved on the outer surface of the fixed rod.

[0009] Preferably, a third gear is fixedly sleeved on the outer surface wall of one of the two movable sleeves, and the outer surface wall of the third gear is meshed with the inner surface wall of the semi-toothed gear. Connecting frames are fixedly installed on the outer surface walls of the two movable sleeves.

[0010] Preferably, a scraper is fixedly installed between the outer surface walls of the two connecting frames, and the outer surface wall of the scraper is in contact with the inner surface wall of the reaction tank.

[0011] Preferably, a temperature and pressure sensor is provided at the top of the inner wall of the reaction tank. An installation groove is formed at the bottom of the rotating shaft, and a heating rod is fixedly inserted into the inner surface wall of the installation groove.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. In the present utility model, after the motor is started, it will drive a set of stirring paddles to rotate through the rotating shaft to stir the internal materials, improving the dispersibility and stability of the dispersant.

Detailed Implementation Manner

[0022] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the following further describes the present utility model in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figures 1 - 5 shown, the present utility model provides an environmentally friendly dispersant preparation device, including a reaction tank 1. The top of the reaction tank 1 is fixedly communicated with an exhaust valve 2, the top of the reaction tank 1 is fixedly communicated with a feed inlet 3, the top of the reaction tank 1 is provided with a shaft hole 4, the top of the reaction tank 1 is provided with a controller 5, the bottom of the reaction tank 1 is fixedly communicated with a discharge outlet 6, the inner wall top of the reaction tank 1 is fixedly installed with a fixed rod 7, the outer surface of the fixed rod 7 is movably sleeved with a gear 1 8, the outer surface of the fixed rod 7 is movably sleeved with a half-tooth gear 9, and the bottom of the gear 1 8 is fixedly connected to the top of the half-tooth gear 9. The top of the reaction tank 1 is fixedly installed with a motor 10, the output end of the motor 10 is fixedly installed with a rotating shaft 11, and the inner surface of the shaft hole 4 is movably inserted with the outer surface of the rotating shaft 11. A group of stirring paddles 12 are fixedly installed on the outer surface of the rotating shaft 11.

[0025] The overall effect achieved by the entire Embodiment 1 is that when preparing the dispersant, only the raw materials need to be poured into the reaction tank 1 through the feed inlet 3. Subsequently, the controller 5 controls the motor 10 to start, driving the rotating shaft 11 to rotate inside the shaft hole 4. The rotating rotating shaft 11 will cause a group of stirring paddles 12 fixedly installed on the outer surface to rotate together, stirring the internal raw materials to ensure the full mixing of the materials during the preparation process, thereby improving the dispersibility, stability, and use effect of the product. When the pressure inside the reaction tank 1 is too high, the exhaust valve 2 can be opened to discharge the excess gas. After the preparation is completed, the dispersant can be discharged from the discharge outlet 6.

[0026] Embodiment 2, as Figures 2 - 5As shown in the figure, a second gear 13 is fixedly sleeved on the outer surface wall of the rotating shaft 11, and the outer surface wall of the second gear 13 is meshed and connected with the inner surface wall of the first gear 8. Two movable sleeves 14 are movably sleeved on the outer surface wall of the rotating shaft 11. A third gear 15 is fixedly sleeved on the outer surface wall of one of the two movable sleeves 14, and the outer surface wall of the third gear 15 is meshed and connected with the inner surface wall of the semi-toothed gear 9. Connecting frames 16 are fixedly installed on the outer surface walls of the two movable sleeves 14. A scraper 17 is fixedly installed between the outer surface walls of the two connecting frames 16, and the outer surface wall of the scraper 17 is in contact with the inner surface wall of the reaction tank 1. A temperature and pressure sensor 18 is arranged at the top of the inner wall of the reaction tank 1. An installation groove 19 is opened at the bottom of the rotating shaft 11, and a heating rod 20 is fixedly inserted into the inner surface wall of the installation groove 19.

[0027] The overall effect achieved by the entire Embodiment 2 is that when the rotating shaft 11 rotates, it will drive the second gear 13 to rotate together. At this time, the rotating second gear 13 will drive the first gear 8 to start rotating in the opposite direction, and the semi-toothed gear 9 fixedly connected to the bottom of the first gear 8 will also start rotating. During the rotation of the semi-toothed gear 9, when the teeth on its surface are meshed and connected with the third gear 15, it will drive the third gear 15 to rotate. At this time, the third gear 15 will drive the internal movable sleeve 14 to rotate on the surface of the rotating shaft 11. The movable sleeve 14 can drive the scraper 17 to rotate through the connecting frame 16, scraping off the materials adhered to the inner surface wall, reducing the time and cost of manual cleaning. Moreover, the semi-toothed gear 9 and the third gear 15 cooperate with each other, enabling the scraper 17 to rotate intermittently, avoiding the scraper 17 from rotating at high speed for a long time, causing additional wear to itself and the inner surface wall of the device, reducing the service life of the device, and also reducing the noise and vibration generated during the rotation of the scraper 17, making the preparation work proceed smoothly. When the device is working, the temperature and pressure sensor 18 can detect the internal temperature and pressure conditions in real time, avoid accidents caused by excessive pressure, and control the internal temperature through the heating rod 20, thereby ensuring that the reaction proceeds under the best conditions and obtaining high-quality products.

[0028] Working principle: During the preparation of the dispersant, the raw materials are introduced into the interior of the reaction tank 1 through the feed port 3. Subsequently, the controller 5 starts the motor 10, and the motor 10 drives the rotating shaft 11 to rotate at a stable speed within the shaft hole 4. This rotational movement activates the 12 stirring paddles fixed on the outer surface of the rotating shaft 11, and they rotate synchronously to stir the internal raw materials in all directions and evenly, ensuring that the raw materials are fully mixed during the preparation process, thereby improving the dispersibility, stability, and usage effect of the dispersant. To cope with the possible internal pressure, the reaction tank 1 is equipped with an air outlet valve 2. After the preparation is completed, the dispersant is discharged through the discharge port 6 for convenient subsequent processing or packaging. The rotation of the rotating shaft 11 also drives the linkage of the gear system. The second gear 13 rotates with the rotating shaft 11, and then drives the first gear 8 and the connected half-tooth gear 9 to rotate in the opposite direction. The tooth surface of the half-tooth gear 9 intermittently meshes with the third gear 15. Each time they mesh, it drives the third gear 15 and the internal movable sleeve 14 to rotate on the rotating shaft 11. The movable sleeve 14 then drives the scraper 17 to rotate through the connecting frame 16 to scrape off the materials adhering to the inner wall. This intermittent rotation mechanism reduces the wear of the scraper 17 and the inner wall of the device, reduces noise and vibration, and extends the service life of the equipment. The system also integrates intelligent control elements such as a temperature and pressure sensor 18 and a heating rod 20. The temperature and pressure sensor 18 continuously monitors the temperature and pressure inside the reaction tank 1. When the pressure inside the tank exceeds the safety threshold, the air outlet valve 2 will be automatically opened by the controller 5 to release the excess gas and ensure production safety. The controller 5 will control and maintain the optimal temperature conditions inside the reaction tank 1 by adjusting the working state of the heating rod 20 to ensure that the chemical reaction proceeds under the best conditions, thereby obtaining a high-quality dispersant product.

[0029] The above are only the preferred embodiments of the present invention, and it is not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
