Waste silver treatment device for silver mirror production line

Abstract

The invention discloses a waste silver treatment device for a silver mirror production line. The waste silver treatment device comprises a sedimentation box, wherein a waste water pipe is connected to the sedimentation box; a dripping tap is arranged above the sedimentation box and is connected to a liquid container; the liquid container is filled with solution of sodium chloride; the side of the sedimentation box is provided with a water outlet which is connected to a filtering pond; a separation plate is arranged in the filtering pond for separating the filtering pond into a front sub-pond and a back sub-pond; the upper end of the separation plate is provided with an overflow opening; a flannel blanket and a filtering bag filled with sawdust are arranged in the front sub-pond of the filtering pond; the back sub-pond is provided with a plurality of filters which are filled with activated carbon; and the lower end of the back sub-pond is provided with a general water outlet. In the waste silver treatment device, a neutralization reaction, multi-level sedimentation and filtering are performed on waste silver-containing water by the ways of arranging the sedimentation box and the filtering pond, adding a chemical agent, and arranging filtering materials such as the flannel blanket, the activated carbon, the sawdust and the like in the filtering pond, so that the discharge volume of the waste silver is controlled effectively and part of the waste silver is recovered so as to gain economic benefits for an enterprise at the same time.

Description

Technical field: [0001] The invention relates to the field of manufacturing equipment for inorganic non-metallic materials, in particular to a waste silver processing device for a silver mirror production line. Background technique: [0002] In the production process of the glass silver mirror, it is necessary to silver-plate the corresponding side of the glass first, so that the glass can reflect light well to form a lens. Silver is a precious metal and an important pollutant. If the waste silver produced by silver plating is directly discharged into the sewage, it will seriously pollute the water source and cause environmental pollution. Invention content: [0003] In order to solve the problems existing in the existing technology, a waste silver treatment device for the silver mirror production line is specially provided. By setting a sedimentation tank and a filter tank, adding chemicals, and setting filters such as wool blankets, activated carbon, and sawdust in it, ...
