A new device for separating copper powder in waste liquid

Abstract

The invention discloses a novel device for separating copper powder from waste liquid. The device includes a working table (1), a filter drum (2), a motor (4), as well as a stand column A (5) and a stand column B (6) which are both arranged on the working table (1), wherein a rotating shaft II (9) is connected with the output end of the motor (4); a cavity (10) is formed in the middle of the filter drum (2); a plurality of through holes (11) communicated with the cavity (10) are distributed uniformly in the cylindrical surface of the filter drum (2); a liquid inlet (12) and a discharge opening (13), which are communicated with the cavity (10), are respectively arranged formed in the upper end and the lower end of the filter drum (2); a plug (3) is arranged in the discharge opening (13); the device further includes a liquid collection bag (14) which surrounds the filter drum (2); a cavity is formed between the liquid collection bag (14) and the filter drum (2). The novel device for separating copper powder from waste liquid has the benefits that the copper powder separation is thorough, separation efficiency is high, and the operation is simple,; manual copper powder collection is facilitated and waste liquid is prevented from splashing.

Description

technical field [0001] The invention relates to a novel device for separating copper powder in waste liquid. Background technique [0002] At present, the surface of most metal parts (such as door handles, keys, etc.) must be copper plated to make the surface brighter. The copper plating on the surface is carried out in the electroplating solution. However, there is a large amount of copper powder in the waste liquid, once it is discharged to the outside, it will not only cause environmental pollution, but also cause waste of copper powder, which is very uneconomical. At present, most enterprises usually use filters to filter out copper powder. The operation is to install a filter at the discharge port of the electrolytic cell. When the waste liquid passes through the filter, the copper powder is intercepted in the electrolytic cell, and the waste liquid passes through the filter. The filter screen is discharged from the electrolytic tank. Although this method can effective...

[0002] At present, the surface of most metal parts (such as door handles, keys, etc.) must be copper plated to make the surface brighter. The copper plating on the surface is carried out in the electroplating solution. However, there is a large amount of copper powder in the waste liquid. Once it is discharged to the outside, it will not only cause environmental pollution, but also cause waste of copper powder, which is very uneconomical.

At present, most enterprises usually use filters to filter out copper powder. The operation is to install a filter at the discharge port of the electrolytic cell. When the waste liquid passes through the filter, the copper powder is intercepted in the electrolytic cell, and the waste liquid passes through the filter. The filter screen is discharged from the electrolytic tank. Although this method can effectively separate the copper powder, the copper powder is easy to block the filter screen, so that the waste liquid cannot continue to be discharged from the electrolytic tank.
