Description

Free-circulation polishing equipment for impeller
Technical Field
The invention belongs to the technical field of surface treatment, and particularly relates to free-circulation grinding equipment for an impeller.
Background
Polishing, which is one of surface modification techniques, generally refers to a processing method for changing physical properties of a material surface by friction with the aid of a rough object (e.g., sandpaper containing particles with high hardness, etc.), and is mainly aimed at obtaining a specific surface roughness; the grinding method comprises three methods of dry grinding, wet grinding and mechanical grinding: dry grinding: and (5) polishing by using sand paper. The method is suitable for polishing hard and brittle paint seeds, and has the defects that a lot of dust is generated in the operation process, the environmental sanitation is influenced, and wet polishing is carried out: and (5) polishing by using a water sandpaper dipped with water or soapy water. The water grinding can reduce grinding marks, improve the smoothness of the coating, and save sand paper and labor. However, when the lower paint is sprayed after the water grinding, the lower paint can be sprayed only after the water grinding layer is completely dried, otherwise, the paint layer is easily whitened. In addition, the base material with strong hydroscopicity is not suitable for water grinding and mechanical grinding: in the case of large-area construction, in order to improve the working efficiency, a mechanical polishing method such as an electric polisher (disc type, vibration type) may be employed.
The impeller is mostly of a curved surface structure, so that the outer surface of the traditional grinding wheel cannot be well attached to the surface of the impeller, and a good grinding effect is difficult to obtain by a grinding mode of the grinding wheel; the back is through improving, polish the impeller through fluidic mode, the mode of implementation mainly is on impacting the impeller through the fluid that has pressure, polish through the mode of scouring, carry out the polishing on impeller surface, but because the impeller majority is the lamellar structure, and then polish from the form that single direction erodees, be difficult to polish all surfaces of impeller, if increase the quantity of dashing the brush head, then increase the manufacturing cost of equipment of polishing, simultaneously because adopt the form of scouring and polishing, the used fluid of polishing does not circulate, and then cause the waste of polishing fluid, and then increased the cost that the impeller was polished, annular shell and the polishing solution through setting up in this scheme, through the rotation of impeller, and then make and rub between impeller and the polishing solution, and then realize that all surfaces of impeller can all be polished, and in-process polishing solution cyclic utilization, and then solved when traditional polishing wheel polished the impeller and polished the impeller can not polish to all surfaces of impeller and current mobile liquid and dash and hit with The problem of waste caused by the fact that flowing liquid cannot be recycled during grinding is solved.
Disclosure of Invention
In order to make up for the defects of the prior art, the invention provides free-circulation grinding equipment with an impeller. The invention is mainly used for solving the problems that all surfaces of the impeller cannot be polished by the traditional polishing wheel when the impeller is polished and the waste is caused by the fact that the flowing liquid cannot be recycled when the traditional flowing liquid is used for impact polishing.
