AI Technical Summary

Technical Problem

The high density of the filter cake in silver-plated copper alloy makes it difficult to dry the internal moisture, resulting in low drying efficiency and an undispersed filter cake after drying, which is not conducive to subsequent processing steps.

Method used

The drying device includes a drying chamber, an electric heater, a triangular filter cloth, a water absorption mechanism, and an extrusion mechanism. The water absorption mechanism, composed of multiple layers of polyester fiber cloth and filter screen, absorbs the moisture in the filter cake. Combined with the extrusion mechanism's extrusion and drying processes, rapid drying and dispersion of the filter cake are achieved.

Benefits of technology

It significantly reduces drying time, enables rapid dispersion of the filter cake, and facilitates subsequent processing steps.

Abstract

The utility model discloses a drying device for recycled silver in silver-plated copper alloy. Comprising a drying bin, an electric heater fixedly connected to the inner wall of one side of the drying bin, triangular prism filter cloth movably connected to the inner wall of the top end of the drying bin, water absorption mechanisms movably connected to the inner walls of the two opposite sides of the drying bin, and a pressing mechanism fixedly connected to the top end of the drying bin. The extrusion mechanisms are fixedly connected to the outer walls of the two opposite sides of the drying bin; the water absorption mechanism comprises multiple layers of polyester fiber cloth and filter screens fixedly connected to the middle positions of all the layers of polyester fiber cloth, and the multiple layers of polyester fiber cloth are stacked at the bottom end of the triangular prism filter cloth; the extrusion mechanism comprises two symmetrically-arranged first electric telescopic rods and extrusion plates fixedly connected to the output ends of the first electric telescopic rods. The drying device for recycling silver in the silver-plated copper alloy has the advantages that the drying time can be shortened to a large extent, meanwhile, dispersion of filter cakes is achieved, and the drying efficiency is improved. And the next treatment procedure can be conveniently carried out.
