Technical field
Steam boiler equipment is the utility model is related to, particularly a kind of electrode assembly of electrode steam boiler.
Background technology
The referring to the electrode for connecting power supply being directly immersed in the stove water that the inner cylinder of boiler holds of electrode boiler is added
Heat produces the device of steam.Existing electrode boiler is that hot spot mainly collects the reason for efficiency is low when water is heated in energization
In region in water body between electrode and the neutral conductor.Heating work(is influenced in order to ensure that the resistance in power delivery circuit is not too large
Rate, it will usually use thicker electrode, but the contact area this results in electrode and water is smaller, the conductive heater area of water body
Block is concentrated, and is unfavorable for the quick heating to water.
Utility model content
The utility model is in view of the above-mentioned problems, propose a kind of electrode assembly of electrode steam boiler.
The technical solution that the utility model is taken is as follows：A kind of electrode assembly of electrode steam boiler, including electrode disk, electricity

Electrode bar between spacing diminish.
Electrode bar is usually to erect to set at work, and lower end mentioned here, which refers to do with gravity when electrode bar is erect, joins
The part on the lower examined, top part are top.Electrode bar bends inwards, and the electrode bar on same cross section is surrounded
Area be gradually reduced, with electrolyte solution water level decreasing, the length for the electrode bar being immersed in electrolyte solution gradually contracts
It is small, electrode bar and fill electrolyte solution inner cylinder barrel between resistance become larger, the efficiency of heating surface of electrode boiler reduces, because
This can realize the control of the size to the resistance in heated by electrodes circuit and the electric current passed through by adjusting inner cylinder water level.Cause
Can continuously it be lifted for liquid level, the area for the part that electrode bar is immersed in electrolyte solution is also consecutive variations, thus
The step-less adjustment to heating power can be achieved.Because the position that electrode bar is set in electrode disk is different, surrounded in electrode bar
Area when uniformly reducing, can be distinct between the amplitude that electrode bar bends inwards.
In one embodiment of the utility model, the electrode disk is equipped with through hole, has screw thread, institute at the top of the electrode bar
State after electrode bar passes through through hole and be installed on by nut in electrode disk.
Electrode bar is installed together by nut and being threaded onto, easy to which electrode bar is adjusted, and when electricity
After pole rod damages in use, replace also more convenient.
In one embodiment of the utility model, the electrode bar is the rectangular flaky texture in cross section.
Cross section is rectangle, can have more external surface areas than cylinder under same volume, with electrolyte solution
The area of contact is also bigger, conductive heater efficiency of the lifting electrode boiler to electrolyte solution.
In one embodiment of the utility model, the electrode supporting pipe includes support base, insulation tube and electrode stem, the branch
Support seat is fastened around insulation tube periphery；The electrode stem is fixedly connected after passing through insulation tube with electrode disk.
Electrode supporting pipe provides support and fixation by support base, due to needing to carry larger stress, support base
Often prepared using the big metal material of structural strength.One layer of insulation tube, Ke Yiyou are set between support base and electrode stem
Avoid to effect the electric current in electrode stem from being conducting to outside by support base, trigger security risk.
The beneficial effects of the utility model are：
Keep adding the contact area of electrode bar and electrolyte solution while relatively low impedance, improve electrode steam
The transmission of electricity of boiler and heating power；Make the fan-shaped arrangement of electrode bar between being located between the electrode and inner cylinder of fan-shaped arc-shaped side
Away from equal, it ensure that the uniformity of electric current conduction, avoid the occurrence of electrolyte solution situation uneven in temperature；Contract electrode stem lower end
Hold together, realize electrodeless adjustment of the water level to heating power by adjusting inner cylinder.
