Screening equipment for controlling powder coating particles

Abstract

The invention discloses screening equipment for controlling powder coating particles, and belongs to the field of powder coating manufacturing. The screening equipment is characterized in that a firstcavity is formed in a box body, a screening mechanism for screening a powder coatings is arranged in the first cavity, an impurity removing mechanism for removing the fine-particle powder coating isarranged on the discharging side of the screening mechanism, and the impurity removal mechanism is connected with a dust removal mechanism. According to the screening equipment for controlling the powder coating particles, multi-stage screening and grinding refining can be conducted on the coating, the situation of repeated refining and screening is reduced, the screening speed is increased, different speeds of rotation are set for a screening barrel, two-stage screening is conducted on the screening barrel with two layers inside during rapid rotation, and the screening speed and the screeningquality both can be guaranteed; and the coating is blown by an air pump and is rolled up and suspended by sweeping pieces, so that the coating can pass through the screening barrel and a screen morequickly, and it is guaranteed that the coating has a better effect in the using process.

Technical field[0001]The invention belongs to the field of powder coating manufacturing, and is specifically a sieving device for powder coating particle control.Background technique[0002]Powder coatings need to control the particle size of the coatings during manufacture. Through experiments, it is found that when the particle size of the coating is 45μm, the performance of the prepared powder coatings is excellent overall, which meets the requirements of production and use, and has good application prospects. Therefore, When powder coatings are manufactured, the particle size of the coatings needs to be controlled to about 45μm, and the coatings with too small particle size will not achieve good results when used, but will affect the spraying.[0003]At present, in order to control the size of the particle size, it is necessary to screen and refine the particles many times, so the manufacture of the paint is slow.

[0002] The powder coating needs to control the particle size of the coating during manufacture. It is found through experiments that when the particle size of the coating is 45 μm, the performance of the prepared powder coating is excellent overall, which meets the requirements of production and use, and has a good application prospect. Therefore, When manufacturing powder coatings, it is necessary to control the particle size of the coating to about 45 μm, and the coating with too small particle size cannot achieve good results when used, but will affect the spraying

[0003] At present, in order to control the size of the particle size, it is necessary to screen the paint many times and refine the particles, so the manufacturing of the paint is slow. In the actual processing process, people only pay attention to the degree of refinement of the paint particles, and the particle size is too small. The paint is often ignored by people because the amount is small and will not have a huge impact on the effect of the paint, so the actual ability to control the particle size of the paint is small
