Summary of the invention
The invention provides a kind of efficient and convenient, regulate accurate, the long-lived liquid level regulation device for electrolytic nickel cell.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of liquid level regulation device for electrolytic nickel cell, comprise electrolyzer, diaphragm bag, negative plate and positive plate, described electrolyzer is provided with regulating tank, electrolyzer is by adjusting liquid hole to be communicated with regulating tank, adjust on liquid hole drainage set is installed, drainage set is divided into communicating pipe, catheter, plug and ventpipe, and regulating tank is communicated with anode liquid bath, header tank is provided with liquid feed valve, and header tank is connected with diaphragm bag respectively.
Described plug comprises baffle plate and splicing mouthful, between baffle plate and splicing mouth, connects by turn buckle, offers gap on baffle plate.
The splicing mouth of described plug was connected with communicating pipe, spliced between mouth and communicating pipe and was provided with sealing-ring.
Described anode liquid bath is communicated with header tank, is connected cleaner and the pump housing between anode liquid bath and header tank.
The material selection CPVC plastics of described drainage set.Beneficial effect of the present invention is:
1, the present invention sets up drainage set and regulating tank, electrolyzer is by adjusting liquid hole to be communicated with regulating tank, adjust on liquid hole drainage set is installed, drainage set is divided into communicating pipe, catheter, plug and ventpipe, regulating tank is communicated with anode liquid bath, header tank is provided with liquid feed valve, and header tank is connected with diaphragm bag respectively.The electrolyte stream of header tank forms catholyte in each cathode compartment diaphragm bag, overflow or ooze out inflow electrolyzer from diaphragm bag and form anolyte, anolyte flows in anode liquid bath by drainage set, circulation of elecrolyte flows, make the nickel ion in electrolyzer distribute more even, reduce nickel residual anode ratio and line rate in electrolytic nickel top is high, improved direct yield and the finished product electrolytic nickel quality of nickel anode.
2, adjust liquid hole to connect pipe and plug, plug comprises baffle plate and splicing mouthful, offers gap on baffle plate.Use gap to flow into anolyte, adjust liquid hole directly not contact with anolyte, improved the work-ing life of electrolyzer.Between baffle plate and splicing mouth, connect by turn buckle, can light 360 ° of butterflys and regulate gap position by turn buckle, accurately revise anolyte liquid level, because catholyte liquid level is constant, by regulating anolyte liquid level to change liquid level difference, improve the scope of application that liquid level regulates.
3, the splicing mouth of plug was connected with communicating pipe, and for convenience detach and maintenance, splices between mouth and communicating pipe and be provided with sealing-ring, has improved the sealing property between pipeline.Drainage set adopts CPVC plastics to make, and can effectively prevent anolyte corrosion drainage set, can in 65 ℃ of-75 ℃ of electrolytic nickel cell electrolyte mediums, use for a long time, and significantly improve work-ing life.
4, anode liquid bath is communicated with header tank, is connected cleaner and the pump housing between anode liquid bath and header tank.Cleaner filters and purifies used anolyte, is again led and is got back in header tank by the pump housing, and anolyte can recycle, and has reduced tooling cost.
