Particle-size-based separating device, system and separating method for water abrasive

Abstract

The invention relates to a particle-size-based water abrasive separating device, a water abrasive system and a particle-size-based water abrasive separating method. The separating device comprises a water screen box body, a material falling box body, a separating screen, and a feeding part, wherein the upper end of the material falling box body communicates with the lower end of the water screen box body, the separating screen is arranged in the water screen box body, and the feeding part is arranged on the water screen box body and is used for feeding a large-particle material and a small-particle material, the aperture of the separating screen is larger than the outer diameter of the small-particle material and less than the outer diameter of the large-particle material; an inner cavityof the material falling box body is at least divided into a mixing cavity and a material falling cavity by the separating screen; the mixing cavity communicates with the feeding part, and the materialfalling cavity communicates with the material falling box body; and at least one part of the separating screen and / or at least one part of the mixing cavity are / is immersed in a liquid. The particle-size-based water abrasive separating device has the advantages of being reasonable in design, compact in structure and convenient to use.

Description

technical field [0001] The invention relates to a particle size-based separation device, system and separation method of a water mill. Background technique [0002] There are two types of abrasives: natural abrasives and artificial abrasives. Classified by hardness, there are two categories of superabrasives and ordinary abrasives. At present, water abrasives have the characteristic of being easy to cluster after encountering water. Due to the clusters, the particles become larger and cannot pass through the screen. Generally, before separating the water abrasives, drying and moisture-proof treatment are required to reduce the moisture content of the abrasives. , thus avoiding clusters. There are also high-pressure water guns or other auxiliary equipment that will impact the clusters to reduce clusters. However, with high-pressure water guns, it is necessary to find clusters, precise impact, water splashes, flushing is not clean, and the remaining liquid will make the abra...
