WO2000056951A1 - Device for applying a coating on the inner surfaces of parts - Google Patents

Abstract

The present invention relates to a device for applying a coating, wherein said device includes the following members: a hopper (1) with a feeder-doser (2) and a mixing chamber (3); means for supplying a working gas to a mixing chamber (5) and to a feeder-doser (4) connected to a gas source (6); and a spraying head (7) that comprises an annular collector (8), an annular supersonic nozzle (9) and a rotating device (10). The rotating device has the shape of a ring and presents an axial symmetry relative to the central axis of the spraying head (7); the rotating device is further connected to and communicates with the annular supersonic nozzle (9). The axis of the annular rotating device (10) is an extension of the central axis of the annular supersonic nozzle (9) and is oriented at an angle of 90° ± 5° relative thereto. The outlet section of the annular rotating device (10) is oriented in a direction opposite to the central axis of the spraying head.

The temperature range of the two-way flow is established by the process and is selected significantly lower than the temperature of the melting of the material of the particles of the waste.

The best embodiment of the invention Let us take an example of an experimental implementation when applying an anti-corrosion resistor made of aluminum (Α1) with a maximum length of 50 mm (2 in.)

The yield of Α1 dispersion up to 50 microns is fed from the supply to the mixer with mass discharge ~ 15 g / s. At the same time, the working gas (air) with a flow rate of 150 g / s at a pressure of 1 μPa and a temperature of 450 ° да is supplied to the mixer. At the entrance to the factory, the vehicle has a speed that corresponds to the number of Karl Μ∞2, the average speed of which is at least 600 m / s. Having come through a simple device, the two-way flow is achieved by the inside of the pipe, which is only suitable for non-refractory materials. Inside the pipe, without its preliminary calculation, aluminum is cleaned with the following characteristics:

- thickness of δ = 50 μm ± 2 μm;

- the output is equal to 450 μPa;

- adhesion to κ Α1 -0.85; - the coefficient of use of the product is -0.98;

- closed income from acquisitions <1%.

The proposed device is uncomplicated to operate.

Bunker, mixing chamber, food-dispenser - standard industrial purpose-made devices. The working gas supply system in the mixing chamber can be made in the form of a product, a pressure gauge, a process valve, a heater with a standard (standard).

Че The processing gas supply system to the dispenser can enter the product, the inlet valve, the exhaust valves, and the optional ones.

The spray head can be manufactured by means of stamping, disassembling, and smoking.

The source of the working gas can be made in the form of an industrial unit of the solutions.
