Parallel turbulent-flow-preventing type copper-powder recovering device

Abstract

The invention relates to a copper -powder recovering device and particularly relates to a parallel turbulent-flow-preventing type copper-powder recovering device. The parallel turbulent-flow-preventing type copper-powder recovering device comprises a water inlet, a water outlet, a filtering net and a pipe shell, wherein the pipe shell is rectangular, a plurality of separating plates are arranged at the middle position in the pipe shell, and are utilized to adsorb and precipitate copper powder on the surfaces of the separating plates; channels are formed between the separating plates, other channels are also formed between the separating plates and the pipe shell, and a plurality of parallel channels are formed. The parallel turbulent-flow-preventing type copper-powder recovering device hasthe beneficial effects that by adoption of the mode, the contact area between copper powder water and the separating plates is enlarged, simultaneously water flow is flatter and slower when flowing through the linear channel, and is shown as a laminar flow. Since the middle parts of the separating plates are rectangular and variable flow ends are arranged at the two ends of the separating plates,the phenomenon that the laminar flow changes into turbulent flow can be effectively avoided, so that the copper-powder recovering rate is increased and the copper powder is finally collected by the separating plates.

Description

technical field [0001] The invention relates to a copper powder recovery device, in particular to a parallel type anti-turbulence type copper powder recovery device. 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 large power consumption, high operating noise and high processing cost, while the sedimentation tank is used for sedimentation, the processing capacity is small, and the copper powder recovery effect is poor.

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.

Moreover, the design of multiple upper and lower baffles is easy to cause turbulence. According to the flow characteristics of water, the internal stratification phenomenon is obvious during laminar flow, the fluid is relatively stable, and it is easier to recover copper powder. When the fluid is turbulent, the copper in the water The powder movement will become volatile and irregular, which is more complicated and difficult to collect
