Description
Technical field
The present invention relates to a kind of Electrolyzed Processing circulate electrolyte filtration system and electrolyte filtering method for supervising, electrolyte component control method, belong to technical field of electrolysis processing.
Background technology
In electrochemical machining process, in workpiece to be machined corrosion moulding, necessarily be accompanied by a large amount of electrolysate-electrolytic slimes, the volume ratio of electrolytic slime is removed metal volume and is wanted large 100-200 times usually, its composition mainly is precipitation of hydroxide, exists with cotton-shaped form in electrolyte.If workpiece to be machined is the carbon containing metal material, because carbon is the poorest element of activity in the electrochemical reaction, in electrochemical machining process, form undissolved particulate, then also have graphite particulate in the electrolytic slime.Carbide is only with Fe in the high-carbon steel
3The C form exists, Fe
3Electrode potential and the carbon of C phase are close, so contain 1% carbon in the high-carbon steel, will have 15% Fe in the electrolytic slime
3C is soluble particles not.
Electrolyte act as in the electrochemical machining process: form the electrochemical system that carries out electrochemical reaction with anode and negative electrode, realize desired electrochemical machining process; Get rid of electrolysate, the control polarization, make anodic solution can be normally, carry out continuously; In time take away the heat that produces in the electrochemical machining process.The circulate electrolyte filtration system is in time carried out filtration treatment to the electrolyte of cathode and anode machining area output, and constantly inputs swiftly flowing cleaning electrolyte to machining area, carries out to guarantee that electrochemical machining process is stable.If along with electrochemical machining process carries out, circulate electrolyte filtration system filters degradation, will cause: the device generation electrolytic slime cloggings such as (1) electrolyte circulation system middle filtrator, the flow of electrolyte of input machining area descends, (2) contain a large amount of electrolytic slimes in the electrolyte of input processing district, machining area electrolyte heat extraction degradation, machining area electrolysate are piled up and can't in time be got rid of.Therefore, the circulate electrolyte filtration system can not stable operation will directly affect the stable of electrochemical machining process carries out, even can produce short circuit phenomenon, makes the cathode and anode serious burn.
Current electrolysis liquid circulated filter system filter method mainly comprises: a plurality of electrolytic bath cascade filtrations, and the plate and frame filter press of connecting between the electrolytic bath, the cell liquor pump inlet arranges coarse filter, and fine filter etc. is set in pipeline.The electrolytic bath cascade filtration namely cuts off electrolytic slime by the dividing plate between the electrolytic bath, electrolyte is by the logical liquid bath circulation in dividing plate middle part, cleaning with the electrolytic bath of guaranteeing to link to each other with cell liquor pump, the method filter effect is general, usually needs coarse filter to be set and fine filter is set in pipeline at the cell liquor pump inlet; The series connection plate and frame filter press filters between the electrolytic bath, can effectively reduce the quantity of electrolytic bath, and filter effect is also better, but because the plate and frame filter press electrolytic slime is piled up comparatively fast, need frequent filter plate, filter frame to plate and frame filter press to clean, and plate and frame filter press generation electrolytic slime is piled up in the electrochemical machining process, will affect the flow of input machining area electrolyte, and then electrochemical machining process stability is exerted an influence.The main cell liquor pump that relies on of current electrolysis liquid circulation, pressure regulator valve, overflow valve and electrolyte pipeline are realized, cell liquor pump constantly detaches electrolyte Zhiyin, Anode machining zone from electrolytic bath, regulates pressure regulator valve and overflow valve openings of sizes and can control input machining area flow of electrolyte and pressure.
