Description

Solid-liquid foam three-phase separator for electrolytic copper liquid purification process

Technical Field

The utility model relates to a separation technology, in particular to a device for separating solid, liquid and foam.

Background

A water conservancy diversion formula centrifuge for clean liquid process of copper electrolysis, clean liquid in-process vacuum evaporator back liquid get into subsequent decoppering process after the water-cooling crystallizer, and the equipment that is used for decoppering at present mainly has two kinds: a diversion centrifuge and a belt type centrifugal filter. The belt type centrifugal filter has large treatment capacity, large equipment volume and large occupied area, and needs to be matched with vacuum equipment, an acid mist collection and treatment system, water washing equipment and the like, and the flow guide type centrifugal filter has few accessories and small occupied area. Compared with the traditional belt filter, the guide-flow type continuous discharging centrifuge not only can efficiently and quickly separate out copper sulfate solid and reduce the water content of copper sulfate, but also can realize closed and continuous operation, further eliminate the harm of on-site acid mist, and has good economic benefit and social environmental benefit.

When the flow guide type centrifuge is adopted, materials enter the centrifuge from the upper part, the material distributor continuously fills the materials into the flow guide channel, the materials flow downwards along the flow guide channel under the action of centrifugal force, liquid enters the liquid collecting bin through the filter screen in the flowing process, and solid materials are discharged into the solid collecting bin at the lower part along the flow guide channel. By utilizing centrifugal force and gravity, the guide-flow centrifuge completes centrifugal filtration and centrifugal discharge simultaneously.

However, the clear liquid separated by the diversion type centrifuge still contains certain solid granular copper sulfate and floating foam on the upper layer, when the clear liquid is pumped to a storage tank in the next process through a pump, crystallization is easy to cause to block a pipeline, the operation of equipment needs to be stopped frequently to clean and dredge the pipeline, and the production efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a solid-liquid foam three-phase separator for a copper electrolysis liquid purification process, which is arranged between a diversion type centrifugal machine and a pumping unit and is used for separating solid, liquid and foam three phases of clear liquid at a liquid outlet of the diversion type centrifugal machine.

A solid-liquid foam three-phase separator for a clean liquid procedure of electrolytic copper is characterized in that: the tank is internally provided with a partition board, the middle part of the partition board is provided with a liquid passage which is lower than the liquid level, the surface of the partition board on the upper part of the liquid passage is higher than the liquid level, and the bottom edge and the side edge of the partition board are closely connected with the tank bottom and the tank wall of the tank and divide the tank chamber into two independent tank chamber areas.

In the scheme, the plate surface of the partition plate on the upper part of the liquid passage is higher than the liquid level, so the foam is intercepted on one side of the partition plate on the upper part of the liquid passage, solid-containing liquid discharged by the diversion type centrifugal machine is injected into one side of the sedimentation tank, the solid is settled on one side of the sedimentation tank, clear liquid overflows from the liquid passage to the clear liquid tank on the other side, clear liquid in the clear liquid tank is accessed by the liquid inlet pipe of the pumping unit, and the solid and the foam are intercepted outside the liquid inlet pipe of the pumping unit.
