Electroplating reclaimed-water recycling device

Abstract

The invention discloses an electroplating reclaimed-water recycling device, comprising a raw water inlet, a filtering assembly, a concentrated water tank and a plain water tank; the filtering assembly comprises a bracket, a rotating shaft, a first filter, a second filter and a vibration device, wherein the rotating shaft is vertically arranged on the bracket in a rotational way, the first filter is fixedly arranged on the rotating shaft and used for filtering particles and organic matters, the second filter is fixedly arranged on the rotating shaft and is used for deionizing, and the vibration device is used for providing a tangential torque for the rotating shaft. The first filter can remove the particles and organic impurities in the raw water, so that the blockage possibility of an ion exchange membrane in the second filter is greatly reduced. Furthermore, filter membranes in the first filter and the second filter are shaken along the plane direction by means of the vibration of the vibration device, so that the filter membranes are automatically cleaned, the filter membranes are not easily blocked by the impurities in filter liquid, and the use replacement periods of the filter membranes are prolonged.

Description

technical field [0001] The invention relates to the field of water purification, in particular to water reuse equipment for electroplating. Background technique [0002] An important factor hindering the development of electroplating industry is water pollution. There are a lot of heavy metals and more toxic additives in electroplating wastewater. Now there has been a kind of reclaimed water reuse equipment used in the electroplating industry, which uses electrodialysis to recover the metal solution in the electroplating wastewater. However, there are many impurities in the electroplating wastewater, and the filter membrane in the equipment is easily blocked, and needs to be replaced frequently or cleaned with liquid medicine. The replaced diaphragm and the liquid medicine for cleaning are likely to cause secondary pollution. Contents of the invention [0003] The object of the present invention is to provide a water recycling equipment for electroplating that reduces se...
