Description

Technical Field

[0001] The utility model relates to the technical field of homogenizing and emulsifying equipment, in particular to a paint homogenizing emulsifier. Background Technique

[0002] As is well known, emulsification and homogenization is a technology often used in the production of the chemical industry. It is a process of atomizing and homogenizing the dispersed particles in a suspension (or emulsion) system. This process simultaneously reduces the scale of the dispersed matter and improves the uniformity of the dispersed matter distribution. The homogenization and emulsification process relies on the shear force generated by the mechanical action of the stirring device to tear the dispersed phase into fine particles and disperse them in the continuous phase to form a milk (paste) - like homogeneous substance.

[0003] For example, the Chinese utility model patent discloses an emulsifier for paint processing (publication (announcement) number CN217594328U), which includes an emulsifier body. A motor is fixedly installed at the top of the emulsifier body. The output end of the motor is fixedly installed with a mixing rod located inside the emulsifier body. A homogenizing head is fixedly installed at the bottom end of the mixing rod. Mixing blocks are fixedly installed on the surface of the mixing rod. A fixed sleeve is fixedly installed on the surface of the mixing rod. Activity openings are opened on both sides of the fixed sleeve. By using the cooperation of the emulsifier body, motor, mixing rod, homogenizing head, mixing blocks, fixed sleeve, activity openings, support rods, impact plates, metal elastic sheets, through openings, dispersion impact covers, conical dispersion blocks and dispersion openings, it solves the problem that the dispersion efficiency of the existing emulsifier remains to be improved. When the emulsifier processes paint, it takes a long time to disperse the material evenly, and it cannot effectively and quickly disperse the paint, reducing the dispersion efficiency of the emulsifier.

[0004] However, when the inventor specifically implemented this device, it was found that there are the following defects: the paint has a high viscosity, the homogenizing head is completely immersed in the paint, and the resistance is large during the mixing and stirring process. The homogenization and emulsification effect of the paint needs to be further improved. The homogenization and emulsification operation time is long, and there are certain limitations in use.

The partition plate 11 divides the inside of the cylinder body 9 into an upper chamber 12 and a lower chamber 13. The sealing plate 10 is provided with a first through hole 14 communicating with the inside of the corresponding upper chamber 12 or lower chamber 13.
