A device for separating copper powder in waste liquid with high degree of automation

Abstract

The invention discloses a device with high degree of automation for separating copper powder in waste liquor. The device comprises a working table (1), a filter cylinder (2), a motor (4) and a stand column A (5) and a stand column B (6) which are arranged on the working table (1), wherein the upper and lower ends of the filter cylinder (2) are provided with a rotating shaft I (8) and a rotating shaft II (9) respectively; the rotating shaft II (9) is connected with an output end of the motor (4); a plurality of through holes (11) communicated with a cavity (10) are uniformly distributed in the cylindrical surface of the filter cylinder (2); the upper and lower ends of the filter cylinder (2) are also provided with a liquid inlet (12) and a discharge hole (13) communicated with the cavity (10); the device also comprises a time counter (14) and a PLC (Programmable Logic Controller) (15); the PLC (15) is connected with the motor (4); the time counter (14) and the PLC (15) are connected. The device has the beneficial effects of compact structure, complete separation of the copper powder, high separation efficiency, convenience in manual collection of the copper powder and high degree of automation.

Description

Technical field [0001] The invention relates to a device for separating copper powder in waste liquid with a high degree of automation. Background technique [0002] At present, the surface of most metal parts (such as door handles, keys, etc.) must be plated with copper to make the surface brighter. The copper plating on the surface is carried out in the electroplating solution. After electroplating, the electroplating solution becomes waste liquid, and the waste liquid is generally directly However, there is a large amount of copper powder in the waste liquid. Once it is discharged to the outside, it not only causes environmental pollution, but also wastes copper powder, which is very uneconomical. At present, most companies usually use a filter to filter out copper powder. The operation is to install a filter at the discharge port of the electrolytic tank. When the waste liquid passes through the filter, the copper powder is intercepted in the electrolytic tank, and the waste ...

Problems solved by technology

[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.
