Embodiment Construction

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Such as Figures 1 to 6 As shown, a rapid color-changing spraying equipment includes a spraying room 1, a cyclone separator 2, a filter recoverer 3, a powder supply center 4, and an electrical box 5. The spraying room 1 is provided with a spraying chamber 11 and a spray gun 6. The bottom of the spraying chamber 11 is provided with a powder recovery device 12, and the powder recovery device 12 communicates with the inlet of the cyclone separator 2 through a pipeline, and the inlet of the cyclone separator 2 leads to a rotary separation chamber 21. The separation chamber 21 is provided with a powder outlet 22 and an air outlet 23. The powder outlet 22 communicates with the powder recovery port arranged on the powder supply center 4 through a pipeline, and the air outlet 23 communicates with the filter element recoverer 3 through a pipeline. The inlet is connected, ...

Abstract

The invention discloses a fast color changing spraying device which comprises a spraying chamber, a cyclone separator, a filter element recoverer, a powder supply center and an electrical cabinet. The spraying chamber is provided with a spray cavity and a spray gun, a powder recovery unit is arranged on the lower portion of the spray cavity, the powder recovery unit is communicated with the inlet of the cyclone separator through a pipe, and the powder supply center is provided with a powder pump, a recovery powder pipe, a powder supply pipe, a reverse getter pump and a powder container, wherein the reverse getter pump is used for intaking airflow so as to intake the powder in the recovery powder pipe and the powder supply pipe into the powder container during color changing. The spraying device has the advantages of being simple in structure, low in cost, good in sealing, high in spraying powder recovery rate, little in pollution, convenient to operate during color changing, few in powder residues in pipes, not easy to mix colors and high in spraying quality.

Description

technical field [0001] The invention relates to the field of metal sheet metal surface treatment, in particular to a rapid color-changing spraying equipment. Background technique [0002] The electrostatic powder spraying process appeared in the 1960s and was mainly applied to metal surface coating. With the rapid development of my country's manufacturing industry, due to the unique advantages of powder spraying technology, such as good environmental performance, simple operation, no organic solvent, and excellent coating performance, the proportion of metal surface treatment continues to increase year by year. It has mostly replaced the original paint coating process. Similar to the painting process, the powder spraying process also places the workpiece in a semi-enclosed space (that is, the spray booth) to prevent the powder that is not on the workpiece from spreading around; but unlike the paint process, it can be effectively carried out in this spray room. Powder recove...
