Sand coating device for electrostatic spraying of steel strand and sand coating method of sand coating device

Abstract

The invention discloses a sand coating device for electrostatic spraying of a steel strand and a sand coating method of the sand coating device, and relates to the technical field of steel strand machining. The sand coating device comprises two bases which are symmetrically arranged; the top surfaces of the two bases are fixedly connected with a group of damping buffer pieces which are connected with each other through connecting rods; a recovery hopper is fixedly mounted at the top ends of the two damping buffer pieces; the bottom surface of the recovery hopper is fixedly connected with two vibration motors which are symmetrically arranged; the top surface of the recovery hopper is fixedly connected with a conveying frame; an annular driving assembly is fixedly connected between the innersurfaces of the conveying frame; the peripheral side surface of the annular driving assembly is connected with an annular conveying filter belt; and a plurality of groups of equidistantly distributedfilter holes are formed in the surface of the annular conveying filter belt. Through the design of the recovery hopper, a material return pipe and the annular conveying filter belt, recovery operation of sand during spraying can be efficiently achieved, unavailable sand can be automatically filtered through the arrangement of the filter holes during spraying operation, and then the recovery effect of the device is fully guaranteed.
