Background
In the prior art, an elastic body is often arranged on an electrode on one side of a membrane-electrode structure body, and the elastic body has various functions, generally speaking, the elastic body is arranged to enable an electrolytic cell to adjust the gap between the electrode and a membrane under different water pressure conditions, so that the gap is suitable for different water flows, the stability of electrolytic reaction is maintained, and the electrode is effectively protected. The elastic piece can compress or relax the electrode plates according to the water quantity, so that the gaps of the electrode plates can be maintained at a relatively constant interval even if the water supply quantity is small, and the electrode is effectively prevented from being burnt out easily due to insufficient water supply quantity of the electrolytic chamber.
Application number 202010229939.0 discloses an ozone electrolysis chamber, the electrolysis intracavity water to this electrode slice punching press, when ejecting it from the conducting film surface, form certain clearance between conducting film and the electrode, be favorable to the ozone bubble of the production on electrode surface to be shifted by the water fast in time, improve electrolytic reaction's efficiency, the electrode slice that is ejected by rivers can realize through the elastomer elasticity and reset, simultaneously, under the effect of rivers and elastomer, the electrode slice is in the micro-oscillation state, can avoid the incrustation scale to pile up on its surface.
Application No. 202010231239.5 discloses an ozone water ultrasonic atomization structure, and elastomeric element's both ends respectively with stainless steel cathode plate and baffle looks butt, the tower spring can make the electrode piece also can realize elasticity after taking place violent electrolytic reaction and reset in order to guarantee the accuracy and the reliability of position.
The electrode slice is arranged in a shell with an electrolysis cavity, and an electrolysis reaction is carried out by introducing an external power supply to the low-voltage electrolysis water body. The electrode plates are relatively and fixedly arranged in the electrolytic chamber, so that the electrode plates cannot greatly deviate in the scouring of water flow, and only keep small-amplitude vibration and displacement.
However, in the above-mentioned applications, it can be seen that the electrode sheet/cathode structure has a right-angled bend in the middle section, as illustrated in fig. 1 (published by application No. 201821493894.2), a1 is the portion of the electrode sheet extending out of the electrolytic cell and connected to the power supply, a2 is the bent fitting portion, and A3 is the working section of the electrode in the electrolytic cell, so that the structure actually limits the displacement of the electrode sheet because the working section is already limited by the bend. In other applications, the electrode plates are arranged in a plane from the working section to the power connection section extending out of the electrolytic cell, and need to be fixedly installed, and the electrode plates are also limited to the installation position.
Electrode slice system is in fixed position, and mobilizable range is limited, is difficult to realize effectual vibrations, displacement, just can not guarantee electrolytic reaction's good stability yet, perhaps provides the ability that the electrode slice avoids the accumulational of incrustation scale with shaking.
