Steel shot screening machine for cleaning metal surface
Technical Field
The invention relates to a steel shot screening machine for cleaning the surface of metal, belonging to the field of steel shot screening equipment for cleaning metal.
Background
After the surface of the metal is produced or used for a period of time, some stains may appear on the surface of the metal, the surface of the metal needs to be cleaned, the cleaning of the metal is different from the cleaning of a conventional object, a common cleaning agent is difficult to clean comprehensively, the problem can be solved well by steel shots, the steel shots have tight structure and uniform granularity, the metal workpieces are cleaned by the steel shots, the basic cleaning effect is achieved, the surface pressure of the metal workpieces can be increased, the anti-fatigue capability of the workpieces is improved to a certain degree, the cleaning efficiency is generally higher, but in the production process of the steel shots, the formed steel shots need to be screened inevitably, a screening machine needs to be used, the structure of the current screening machine is generally simpler, most of the current screening machine is simple in structure, and the steel shots which do not meet the requirements can be filtered, there are some areas where improvement can be achieved;
present shot sieve separator on the one hand can only filter the shot that does not conform to the requirement mostly, perhaps will conform to the shot of requirement and filter, and in the production process of reality, the shot that probably has multiple diameter needs to be filtered simultaneously, present sieve separator just can't satisfy the user demand, on the other hand, present shot sieve separator can't filter some oval shots, these oval shots can't get into next layer through the filter screen promptly, also can not satisfy the user demand, need carry out subsequent screening.
