A continuous cold-spraying wax powder preparation device

Abstract

The application relates to a continuous cold-spraying wax powder preparation device, which comprises a centrifugal atomizer and a molten wax tank, the bottom of the molten wax tank is connected with a discharge pipe, the middle of the discharge pipe is fixedly installed with a control valve, one side of the centrifugal atomizer is provided with a single screw pump, the input end of the single screw pump is connected with a feeding pipe, and a smooth mechanism for preventing the single screw pump from being blocked is arranged between the feeding pipe and the discharge pipe; a hot air blower is started, so that hot air flows into an adjusting cylinder, since the extending end of the cylinder is the longest, at this time, a piston is located between the input end of a first air inlet pipe and the output end of the hot air blower, the hot air flows into a gas guide sleeve along a second air inlet pipe, and is blown out from the top of the gas guide sleeve, so that heat is not only transferred to the discharge pipe above the control valve, but also heats the connecting position between the discharge pipe and the molten wax tank, local temperature fluctuation caused by the opening and closing of the control valve is avoided, fluid stagnation caused by the local temperature fluctuation is avoided, wax liquid is prevented from being solidified and accumulated, and the efficiency of the wax powder preparation is prevented from being affected.
