This paint surface cleaning device based on high-efficient heliciform washing sweeps nozzle's theory of operation: when the cleaning device works, a surface to be cleaned or a workpiece enters the cleaning device housing through the cleaning device opening in a downward extending mode, the cleaning solvent and the high-pressure gas alternately pass through the annular gas-liquid pipeline and sequentially spray the cleaning solvent and blow-dry airflow through the annular cleaning and blowing nozzle, and therefore the cleaning and blow-dry operations of the surface to be cleaned or the workpiece are completed. The cleaning solvent who erupts can produce a spiral helicine washing and blowing face on the whole to the outer wall of cup of treating cleaning surface or work piece along the equidirectional is washed to certain angle, and then the air current that weathers that erupts will treat cleaning surface or work piece surface's residual water droplet with the form of air knife with higher spiral air current of relying on and strike off totally, scrapes residual water droplet to cleaning device's bottom, and then the reinforcing effect of weathering. To sum up, this heliciform washs paint surface cleaning device who sweeps nozzle can strengthen belt cleaning device emphatically and weather the effect of blowing clean, and then shortens belt cleaning device's single washing beat, improves spraying quality and spraying efficiency.

The gas-liquid purging ring is provided with a universal positioning boss and a universal positioning groove, so that the relative angle position of the gas-liquid purging ring can be freely adjusted up and down. The surface to be cleaned or the surface of a workpiece is cleaned by combining 6-7 layers of gas-liquid purging rings, wherein the gas sealing ring positioned on the uppermost layer in the annular cleaning and purging nozzle increases the gas sealing effect beyond the sealing of the physical sealing ring, and the pollution to the closed clean space of a spraying workshop after residual paint droplets and volume droplets in the cleaning device splash is effectively prevented in the whole cleaning process. In addition decurrent spiral air current can make the dropping liquid concentrate on belt cleaning device's bottom in this application, and avoids paint dropping liquid and volume dropping liquid to splash inside belt cleaning device, and the above good sealed effect and dropping liquid concentrate the cooperation between them and can avoid the dropping liquid in the belt cleaning device to leak outward to the at utmost, and then guarantee the cleanness in whole closed spraying workshop.

The gas-liquid purging rings from the second ring to the last ring in the annular cleaning and purging nozzle can be mutually compatible and replaced, the positions of the gas-liquid purging rings can be adjusted up and down (namely the axial distance between two adjacent gas-liquid purging rings can be adaptively adjusted) and the angle can be adjusted around the central axis, so that different parameters such as the downward inclination angle of the jet orifice, the diffusion taper angle of the jet orifice, the aperture of the jet orifice and the like can be adjusted. Aiming at the surfaces or workpieces to be cleaned sprayed with different shapes and different surface structures, the parameters of the jet orifice can be adjusted, the spraying coverage position of the cleaning solvent, the outlet flow of the blow-drying airflow and the internal fluid dynamic parameters such as the angle between the contact point of the target blow-drying airflow and the surfaces are modified and adjusted, so that the cleaning and blow-drying effects are optimized, the cleaning cycle time of the whole surfaces or workpieces to be cleaned is shortened by using the minimum amount of solvent and the fastest blow-drying time, and the spraying production takt is finally improved.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
