A coarse sand shaker classification box

Abstract

The invention discloses a classification box of a coarse sand table. The classification box of the coarse sand table comprises a sluice box, sand blocking bars, an angle iron bracket and a tapered classification chamber, wherein the sand blocking bars are installed between the sluice box and the angle iron bracket, a sand core rod is arranged at the front end of a sand discharging elbow pipe, a conical surface of the head portion of the sand core rod is a sand core cone valve, multiple cone valve upper sand discharging grooves are formed in the sand core cone valve, and the notch of each cone valve upper sand discharging groove is downward formed along the conical surface of the sand core cone valve. According to the classification box of the coarse sand table, due to the fact that the multiple cone valve upper sand discharging grooves are formed in the sand core cone valve and evenly distributed on the sand core cone valve, the traditional linear sand discharging is replaced with the groove type sand discharging, the problem that a bottom valve of a table classifier is prone to blockage during sand discharging due to the fact that the surface of the sand core cone valve is smooth is ingeniously avoided, normal classification and distribution of the table classifier are guaranteed, and the working efficiency during table classification is improved.

Description

technical field [0001] The invention relates to the field of ore dressing and classification, in particular to a coarse sand shaker classification box which is used for particle size classification and distribution of ore pulp before shaker sorting, and which can prevent the bottom valve of the shaker classifier from being easily blocked when sand is discharged. Background technique [0002] At present, in the field of mineral processing, the classification equipment for grinding and classification operations is based on the principle of different sedimentation velocities in liquids due to the different sizes and specific gravity of solid particles, using gravity and centrifugal force to achieve separation. At present, the structure of the classification equipment on the coarse sand shaker generally includes a flow ore chute, a sand blocking bar, an angle iron frame, a cone-shaped classification chamber, and a sand discharge elbow, and the sand blocking bar is installed betwe...
