Spray material separation device and spray processing device

Abstract

The purpose of the present invention is to provide a blasting material separation device etc. capable of efficiently separating a blasting material and a foreign material, which is heavy and has a diameter greater than that of the blasting material, but smaller than the diameter of the holes in a rotary screen positioned upstream from a wind-selection-type separator or the diameter of the openings of a sieve. This blasting material separation device for a shot processing apparatus is characterized by being provided with: a first cylindrical sieve means, which is positioned on a transport path for a mixture of blasting material that has been blasted at a workpiece and the product resulting from blasting with the blasting material, and in which multiple first holes are formed, said first holes having dimensions that allow the blasting material to pass through; a feed mechanism, which feeds the mixture to a space inside the first cylindrical sieve means; a first driving mechanism, which rotationally drives the first cylindrical sieve means around an axis in the longitudinal direction; and a second cylindrical sieve means, in which multiple second holes are formed, said second holes having dimensions that allow the blasting material to pass through and are smaller than the diameter of the first holes, and which has a cylindrical form with a larger diameter than the first cylindrical sieve means, and which is positioned outside of the first cylindrical sieve means.

Description

technical field [0001] The present invention relates to a blasting material separation device and a blasting treatment device, in particular, to a blasting material separation device for separating the blasting material from a mixture of the blasting material sprayed onto a workpiece and products brought about by the blasting, and a device equipped with such a separation device Spray treatment unit. Background technique [0002] In a blasting treatment apparatus that blasts a workpiece by blasting the blasting material, the blasted blasting material is recovered and reused from the viewpoint of cost reduction, resource saving, and the like. In such a recycling process, it is necessary to separate (distinguish) recyclable blasting materials from foreign matter generated by blasting. As a device for separating sprayed materials and foreign substances, a device for separating sprayed materials and foreign substances by combining a wind separator and a vibrating screen is known...

Problems solved by technology

[0007] Since it is difficult to separate such heavy foreign matter from the blasted material in the winnowing type separator, it is also difficult to separate such heavy foreign matter from the blasted material with high precision in the above structure.
