Sorting device with sand and stone sorting function

Abstract

The invention relates to the technical field of building construction, and discloses a sorting device with a sand and stone sorting function. The sorting device comprises a multi-stage sand sorting device, a sand discharging device and a collecting tank, wherein the multi-stage sand sorting device comprises a screening mechanism, a rotational flow sand sorting mechanism and a conveying system; the screening mechanism is used for screening large-particle sand and stone and medium-particle sand and stone, the rotational flow sand sorting mechanism comprises at least one cyclone, the cyclones are used for screening small-particle sand and stone, and the conveying system is used for conveying to-be-screened sand and stone to the screening mechanism and the rotational flow sand sorting mechanism; the sand discharging device comprises a discharging groove and a vibrator; and the collecting tank is arranged below the discharging groove. According to the sorting device with the sand and stone sorting function, the large-particle sand and stone, the medium-particle sand and stone and the small-particle sand and stone can be separated out, the sand and stone of various different sizes can be separated and screened, and the sand and stone screening efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a sorting device with the function of sorting sand and gravel. Background technique [0002] Fluid cyclone is a common separation and classification equipment. The basic principle of the cyclone is to separate the liquid-liquid, liquid-solid, liquid-gas and other two-phase or multi-phase mixtures with a certain density difference under the action of centrifugal force. The mixed liquid enters the cyclone tangentially under a certain pressure, and a high-speed rotating flow field is generated in the cylindrical cavity. The components with high density in the mixture move downward in the axial direction and outward in the radial direction under the action of the swirling flow field, and move downward along the wall of the vessel when they reach the cone section, and are discharged from the bottom flow port, thus forming The external vortex flow field is formed; the c...
