Gravel separator adopting step-by-step centrifugation

Abstract

The invention discloses a sand-stone separator adopting step-by-step centrifugation, which comprises a cylindrical separator body, in which a plurality of centrifugal separation plates are sequentially arranged from top to bottom, and a plurality of centrifugal separation plates are arranged in the center of the centrifugal separation plate. The rotating shaft of the centrifugal separation plate, the rotating shaft drives the centrifugal separation plate to rotate in the horizontal direction; the outer ring on the centrifugal separation plate away from the rotating shaft is provided with a plurality of separation holes in the ring direction, and the plurality of centrifugal separation plates from top to bottom The size of the separation holes on the separator decreases successively; a protective cover is provided on the upper side of the separator body, and a feeding port is provided above the protective cover. The sand and gravel separator of the present invention can separate sand and gravel step by step, and in the process of step-by-step separation, it can fully stir two kinds of sand with similar particle size and size, and improve the efficiency of subsequent high-demand particle size sand. The separation effect is high, and one device can meet the separation requirements of different sand particle sizes, which saves costs and improves work efficiency.

Description

technical field [0001] The invention relates to a drying device, in particular to a sand-stone separator adopting step-by-step centrifugation. Background technique [0002] The sand and gravel separator is a common separation equipment in the concrete industry. It uses the centrifugal principle to separate the sand from the stones, and discharges the sand from one of the outlets and the stones from the other outlet. However, even the sand separated by the sand separator includes sand of various particle sizes, and the individual particle sizes vary greatly. In some occasions that require relatively high sand grains, especially the exterior walls of high-end residential areas, finer sand needs to be used. By starting the centrifuge and making it rotate at a high speed, the two different substances are separated. Although this separation method can satisfy the separation of most substances, for two kinds of sand particles with similar particle sizes, if the centrifuge is dir...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that although the separation method can satisfy the separation of most substances, for two kinds of sand particles with similar particle sizes, if the centrifuge is directly put into the high-speed rotation mode, the two substances will be separated. Separation without stirring evenly, the separation effect is not good, and the separation is not thorough, resulting in low efficiency. Separation, and in the process of step-by-step separation, two kinds of sand particles with similar particle sizes can be fully stirred evenly, and the separation effect of subsequent high-demand particle size sand can be improved, and one device can meet the separation requirements of different sand particle sizes , saving costs and improving work efficiency
