W-shaped copper powder recovery pipe

Abstract

The invention relates to a copper powder recovery device, in particular to a W-shaped copper powder recovery pipe. The copper powder recovery pipe comprises a water inlet, a water outlet, a filter screen and a bent pipe; the projection shape of the front surface of the bent pipe is W-shaped, so that the contact area between copper powder water and the inner wall of the bent pipe is increased; felthairs are arranged on the surface of the inner wall of the bent pipe so that copper powder in the water can be easily precipitated and adhered, and collecting ends are arranged at the lower end of the bent pipe; and the filter screen is in a hemispherical shape. According to the W-shaped copper powder recovery pipe, the bent pipe is designed to W shape so as to increase the contact area between the copper powder and the inner wall of the bent pipe, meanwhile, the felt hairs are coordinated to use so that the copper powder can be easily adsorbed and precipitated on the inner wall of the bent pipe, the copper powder is collected by the collecting ends, and therefore the recovery rate of the copper powder is improved.

Description

technical field [0001] The invention relates to a copper powder recovery device, in particular to a W-shaped copper powder recovery pipe. Background technique [0002] In industrial production, a certain amount of copper powder will be produced, most of which will flow into wastewater. In order to realize the recovery of copper powder in wastewater, the existing copper powder recovery device has high power consumption, high operating noise and high treatment cost, while using a settling tank for sedimentation has small processing capacity and poor copper powder recovery effect. [0003] In response to the above problems, the patent CN201510329892 carried out a scheme design. This scheme adopts multiple upper and lower baffles and filter plates to realize the recovery of copper powder. After analyzing the scheme, it is found that the scheme mainly realizes copper powder through filtering technical means. Recycling, but in reality, the copper powder in wastewater is mostly in...

In order to realize the recovery of copper powder in wastewater, the existing copper powder recovery device has high power consumption, high operating noise and high treatment cost, while using a sedimentation tank for settlement has small processing capacity and poor copper powder recovery effect

[0003] In response to the above problems, the patent CN201510329892 carried out a scheme design. This scheme adopts multiple upper and lower baffles and filter plates to realize the recovery of copper powder. After analyzing the scheme, it is found that the scheme mainly realizes copper powder through filtering technical means. Recycling, but in reality, the copper powder in wastewater is mostly small particles. If the filter hole is larger, the filtering effect will be poor. If the filter hole is smaller, it will be easily blocked, so this solution is difficult to achieve in practical applications.
