Paint bubble removal device

Abstract

The invention relates to the technical field of paint production equipment, and discloses a paint bubble removal device. The paint bubble removal device is characterized in that a cover plate is arranged at the upper end of a barrel, and a discharge outlet is formed in the lower end of the barrel; a feed inlet and a vacuumizing opening are fixedly connected onto the cover plate; a stirring assembly is arranged in the barrel and comprises a driving rotary shaft, the top of the driving rotary shaft extends out of the barrel, and a motor is connected with the top of the driving rotary shaft; a driving gear is fixedly arranged on the driving rotary shaft and is positioned outside the barrel; a driven rotary shaft is further arranged in the barrel, the top of the driven rotary shaft extends outof the barrel, and a driven gear is fixedly arranged on the top of the driven rotary shaft and is connected with the driving gear in a meshing manner; stirring blades are arranged on the driving rotary shaft and the driven rotary shaft; support plates are fixedly connected onto the driving rotary shaft and the driven rotary shaft by bearings; a heating assembly is fixedly arranged outside the barrel. The paint bubble removal device which is a quick defoaming device has the advantages that the paint bubble removal device is high in paint oil stirring efficiency; paint can be dramatically turned over and mixed, accordingly, bubble in the paint can be easily and quickly spilled over, the paint bubble removal device is short in defoaming time, and good defoaming effects can be realized by thepaint bubble removal device.

Description

technical field [0001] The invention relates to the technical field of paint production equipment, in particular to a paint defoaming device. Background technique [0002] Paint is a chemical mixture coating that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. Coatings are generally composed of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives. According to performance requirements, sometimes the composition will change slightly, such as varnish without pigments and fillers, and powder coating without solvent. In the process of paint production, it is usually necessary to mix a variety of raw materials together, so the stirring device is the most commonly used equipment. Paint raw materials are different from solid particle raw materials. Most of the raw materials are liquid with strong fluidity. Due to the limited mixing degree of traditional paint mixers, it is difficult to...

AI Technical Summary

Problems solved by technology

The air mixed in the paint will produce air bubbles, which will directly affect the quality of the finished paint, and its texture will be uneven. After coating, a smooth paint film cannot be formed.

In addition, if the air bubbles in the paint burst after coating, the paint surface will be pitted and the quality of the paint surface will be poor

And after a certain period of time, the pits are prone to peeling and peeling, exposing the surface of the substrate, which is not conducive to the anti-corrosion and anti-rust protection of the substrate.

If the paint peeling off is not dealt with in time, there is a tendency to continue to expand
