Problems solved by technology
[0004] The existing powder feeder can only deliver the same type of powder. For example, if there are two types of powder classified by weight, it can only transport light-weight powder or heavy-weight powder, and the powder feeding type is single.
[0005] For example, when the powder feeder used for powders with heavy weight and large particle size is used to transport powder with light weight and small particle size, it is prone to problems of uneven powder feeding and difficult control of powder feeding volume
However, the powder feeder used for powders with light weight and small particle size is prone to the problems of small powder feeding volume and powder feeding blockage when conveying heavy weight and large particle size powder.

The present disclosure relates to the technical field of cold spraying technology, in particular to a powder feeding system for cold spraying, which includes a powder feeder, a powder collecting device, a powder amount measuring device, a cold spraying gun and a gas transportation unit. The powder feeder includes the main body of the powder feeder, the powder drop barrel and the powder transfer device, so that the powder feeder can transport light or heavy powder; the powder collection device includes a powder collection bucket and a vulcanized plate, and the vulcanized plate is set in the powder collection bucket to Filter and collect the powder output by the powder feeder; the powder volume measuring device measures the weight of the powder collected by the powder collection device; the gas transportation department is responsible for connecting various parts of the cold spray powder feeding system, and the powder feeder can realize the delivery of light or heavy powder through valve control. The quality powder is sent to the cold spray gun for spraying or sent to the powder collection device for collection, and then the powder feeding amount is measured by the powder amount measuring device. The powder feeding system for cold spray coating of the present disclosure provides a transportation mode for multiple types of powders, and is applicable to the transportation of different types of powders.
Description
technical field [0001] The present disclosure relates to the technical field of cold spraying technology, in particular to a cold spraying powder feeding system. Background technique [0002] As a new technology of material surface modification, cold spraying sprays powder onto the substrate by gas-solid two-phase flow at room temperature or lower temperature to form a dense coating, which can be difficult to achieve in some non-heat-resistant or limited heat-resistant thermal spraying. Spraying on the surface of the material. [0003] In the cold spraying system, the powder feeder is used as powder storage and conveying equipment, and its powder feeding uniformity and continuity are important factors affecting the surface performance of the coating. [0004] The existing powder feeder can only convey the same type of powder. For example, two kinds of powders classified by light and heavy quality can only convey the powder of light mass or the powder of heavy mass, and the ...
