Fine sand recovery device

Abstract

The invention discloses a fine sand recovery device comprising a support frame, a material storage box and a material returning box, wherein the material storage box storing sewage and the material returning box storing mortar subjected to centrifugal classification are respectively arranged on the support frame; a sand-water separating device is arranged above the material storage box; the material returning box is provided with a swirler; a front-end outlet of the swirler is arranged above the sand-water separating device, and a rear-end outlet of the swirler is communicated with the material returning box; a slurry delivering machine is arranged below the swirler and is driven by a motor; and a delivery pipeline communicated to the upper end of the swirler is arranged on the slurry delivering machine. The fine sand recovery device has novel and unique structure, is stable in operation, not only enhances the fine sand recovery capacity of equipment, effectively reduces the loss quantity of fine sands and enables the loss quantity to be controlled within 5-10 percent, but also well solves the problems of excessively coarse fineness moldulus and excessively low stone powder content of finished sands, which are generated in an artificial aggregate processing system.

Description

technical field [0001] The invention relates to a fine sand recovery device. Background technique [0002] At present, most of the existing artificial sand production lines adopt wet processing production technology. In the traditional artificial sand wet processing technology, the mud washing and dehydration of artificial sand use spiral sand washing machines, and the loss of artificial sand, especially fine sand, is almost impossible. Control, its disadvantage is that the fine sand with a particle size below 0.16mm is seriously lost, and some even exceed 20%, resulting in unreasonable gradation and coarse fineness modulus. Contents of the invention [0003] The problem to be solved by the present invention is to provide a fine sand recovery device with a novel structure, uniqueness and stable operation, which not only improves the ability of the equipment to recover fine sand, but also can effectively reduce the loss of fine sand, so that it can be controlled at 5-10% I...
