Description

Technical Field

[0001] This utility model relates to the technical field of water-based coating production equipment, specifically to an emulsification device for the production of water-based coatings. Background Technology

[0002] Emulsification of water-based coatings refers to the process of reducing the surface tension between liquids and pigments using emulsifiers, enabling them to mix uniformly. In the production of water-based coatings, emulsifier molecules diffuse onto the surface of pigment particles, forming an emulsion coating layer that stabilizes the emulsion system. Emulsification of water-based coatings not only improves the application performance of the coatings but also ensures their stability and quality.

[0003] For example, CN 222900808 U discloses an emulsification device for the production of water-based coatings, which includes a tank. A stirring shaft for emulsifying the water-based coating is rotatably mounted inside the tank, and a sleeve located inside the tank is snapped onto the top surface of the stirring shaft. A cross plate for support is integrally formed on the outer wall surface of the sleeve. When producing water-based coatings using the emulsification device, the rotation of the stirring shaft inside the tank agitates the water-based coating. Simultaneously, the stirring shaft easily drives the cross plate around the sleeve to rotate, and the conical rubber plate mounted on the outer T-shaped rod of the cross plate also rotates accordingly, facilitating the scraping of the water-based coating adhering to the inner wall surface of the tank. The flexible conical rubber plate reduces scratches caused by friction with the inner wall of the tank, and the conical agitator can be disassembled and replaced simply by unscrewing the screw on the surface of the conical rubber plate. However, the following problem still exists: the bottom of the tank is more prone to coating deposits, making cleaning difficult. Utility Model Content

[0004] The purpose of this invention is to provide an emulsification device for the production of water-based coatings that is structurally sound and reliable in use, solving the problem of the bottom of the tank being difficult to clean, effectively cleaning the inner wall and bottom of the tank, and also facilitating the replacement of the scraper blade.

[0005] The technical solution of this utility model is:
