Description

Technical Field

[0001] This utility model relates to the field of stirring devices, and in particular to a water-based adhesive preparation reactor. Background Technology

[0002] Water-based adhesives are adhesives made from film-forming materials that can be dispersed or dissolved in water. They are also known as water-soluble adhesives. A reaction vessel is required when preparing water-based adhesives.

[0003] Because water-based adhesives have a certain viscosity during the re-preparation process, conventional reactor stirring devices, where one end of the stirring rod is connected to the transmission structure, are prone to vibration when rotating at high speed. Slowing down the stirring speed requires a longer working time to mix the water-based adhesive evenly. Moreover, conventional reactor stirring devices are difficult to mix the adhesive at the bottom evenly, resulting in localized uneven mixing. Some of the prepared water-based adhesive has higher viscosity, and the reactor needs to be pressurized during discharge to quickly discharge the mixed adhesive. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a water-based adhesive preparation reactor, which aims to improve the problems of slow stirring speed, uneven stirring, and the need for additional pressure for discharge during equipment use.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a water-based adhesive preparation reactor, including a support frame, a tank body fixed on the support frame, a feed inlet and a negative pressure interface at the top of the tank body, and a discharge outlet at the bottom. A stirring assembly extending into the tank body is also installed at the top of the tank body. The stirring assembly includes a motor and a transmission box located outside the tank body, and a stirring rod extending into the tank body. Multiple stirring support rods are evenly distributed from top to bottom on the stirring rod. A flywheel is fixed at the bottom of the stirring rod near the bottom of the tank body but not in contact with each other. The flywheel has multiple convex arc-shaped grooves facing the stirring direction at its bottom. The central convergence point of the multiple arc-shaped grooves is aligned with the discharge outlet. When the reactor is stirring, the arc-shaped grooves can throw the adhesive from the bottom of the tank body out, preventing adhesive deposition at the bottom and resulting in uneven mixing. When discharging the adhesive, the discharge outlet is opened and the stirring rod is reversed, allowing the arc-shaped grooves to press the adhesive from the tank body into the discharge outlet at the bottom of the tank body for rapid discharge.

[0006] As a further description of the above technical solution:

[0007] The flywheel is equipped with multiple arc-shaped stirring plates that radiate evenly outward from the stirring rod, with their concave surfaces facing the stirring direction. The adhesive-facing surface of the arc-shaped stirring plates is inclined, which reduces the stirring resistance while achieving the stirring function, and provides forces to the colloid in multiple directions, making the colloid more evenly stirred. The adhesive-backing surface is straight, and when the stirring rod is reversed during discharge, it can guide the colloid to the side wall of the reactor, allowing it to be discharged more quickly through the bottom arc-shaped groove, reducing residue in the reactor.

[0008] As a further description of the above technical solution:

[0009] The stirring support rod has an inclined surface facing the colloid during stirring. While achieving the stirring function, it reduces the resistance to stirring and provides an inclined force to the colloid, making the colloid more evenly stirred.

[0010] As a further description of the above technical solution:

[0011] The bottom of the tank is arc-shaped, and the flywheel fits into the bottom of the tank in an inverted spherical crown shape.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, by providing a flywheel at the bottom of the stirring rod, the vibration of the stirring rod during rapid stirring is reduced, enabling the stirring rod to operate stably at higher speeds;

[0014] 2. In this utility model, by providing multiple arc-shaped grooves with convex surfaces facing the stirring direction at the bottom of the flywheel, the colloid at the bottom of the tank can be thrown out during stirring, avoiding uneven stirring of the colloid at the bottom; by aligning the center convergence points of the multiple arc-shaped grooves with the discharge port, the stirring rod is rotated in the opposite direction during discharge, so that the colloid gathers towards the center through the arc-shaped grooves and provides outward pressure, opening the discharge port to achieve rapid discharge;

[0015] 3. In this utility model, multiple arc-shaped stirring plates are provided on the top of the flywheel, which radiate evenly outward from the stirring rod and have their concave surfaces facing the stirring direction. The adhesive-facing surface of the arc-shaped stirring plate is inclined, which generates forces in multiple directions when the colloid is stirred, making the stirring more uniform. The adhesive-backing surface is straight, which can guide the colloid to the side wall of the reactor when the stirring rod is reversed during discharge, so that it can be discharged more quickly through the bottom arc-shaped groove, reducing residue in the reactor.
