TECHNICAL FIELD
[0001] The utility model relates to spraying coating film processing technical field, especially in spraying coating film processing device. BACKGROUND
[0002] In industrial production, spraying coating film is a widely used surface treatment technology, which can form a protective film on the surface of the workpiece, thereby improving the corrosion resistance, wear resistance and aesthetic performance of the workpiece. However, the quality of spraying coating film is highly dependent on the cleanliness of the workpiece surface. If the workpiece surface has oil stains, dust or other impurities, it will cause uneven coating, poor adhesion, and even coating peeling problems.
[0003] At present, the common equipment for surface cleaning of workpieces before spraying coating film is usually: a plurality of fixed position nozzles are arranged in a cleaning tank, and the washing liquid is delivered to the nozzles through pipelines, and then directly sprayed and washed to the workpieces placed at the bottom of the cleaning tank. In the cleaning process, the washing liquid will mix with the impurities on the surface of the workpiece, and finally be discharged from the drain at the bottom of the cleaning tank. However, this traditional cleaning method has many defects. On the one hand, after cleaning is completed, the washing liquid will remain on the surface of the workpiece, which will affect the quality of subsequent spraying coating film. On the other hand, since the mixture of washing liquid and impurities on the surface of the workpiece is directly discharged from the drain, the washing liquid is difficult to recycle, the utilization rate of washing liquid is low, and the consumption is large. Therefore, a spraying coating film processing device is needed to solve the above problems. CONTENT OF THE UTILITY MODEL
