Description
The present invention is a kind of electrode cleaning device general in fluid.Electrode is widely used in electrochemistry, and the occasion that has requires electrode to clean automatically down in working order.Existing electrode cleaning device except that uncommon ultrasonic cleaner, mainly is made up of motor, eccentric wheel, connecting rod, slide block etc., also has the fluid dynamic utilized to drive screw or impeller.Their shortcoming is: complex structure, can not miniaturization, eccentric wheel, linkage have the alternation radial component, make the electrode fatigue break easily, and load when becoming big the torque of motor also become greatly, that is to say meets with obstruction can not stop, this factor also makes electrode damage easily, in addition, they all can only be special-purpose, can not be general.
Task of the present invention provides the electrode cleaning device that a kind of simple structure, little, not fragile, the difform electrode of volume all are suitable for (promptly so-called " general ").
The electrode cleaning device that the present invention is general is made up of infundibulate shell (1), spherical spinner (2), friction part critical pieces such as (3), sees accompanying drawing 1, Fig. 2 (reference electrode does not draw).With its vertical orientation be connected in the fluid line of electrode work, just can utilize fluid to drive, carry out cleaning.
Embodiment one, the electrode that can freely process for sensitive area, and metal one metal oxide electrode for example, its cleaning device is fairly simple.Now take widely antimony one antimony oxide electrode (hereinafter to be referred as antimony electrode) (4) details are as follows for example:
With the vertical placement of infundibulate shell (1), glass marble is that spherical spinner (2) is placed in one, and the concave spherical surface that the end face of antimony electrode (4) is made and glass marble coincide is as the sensitive area that is cleaned.Antimony electrode is packed among the infundibulate shell coaxially, and sensitive area is above glass marble, at a distance of a small distance (about 1 millimeter).Be provided with O shape elastic washer (6) below the fastening nut of electrode (5), play holding electrode and sealing, and can allow electrode do the adjustment of axial location.Utilize the potential energy of fluid after having assembled or with pump fluid is imported from bottom to up, glass marble is followed the reciprocal axial displacement of generating period simultaneously just by the fluid driven rotary, and the sensitive area of antimony electrode is subjected to the periodic shock of glass marble and grinding and cleans up.Flow out from infundibulate shell upper opening after the fluid work done, collect or discard.
When fluid flows through diffusion admittance and walks around spheroid with radiation mode, can drive the spheroid rotation.This is existing expression in Soviet Union description of the invention SU-941665, and the present invention has done further simplification and improvement and has been applied in the cleaning of the electrode of working in the fluid.The remarkable improvement of the more above-mentioned Soviet Union of the present invention invention is to start voluntarily.Turning to during starting is at random, but once rotating turning to of just relatively keeping determining.For cleaning, turning to does not have decisive action, can select arbitrarily.Under the same conditions, rotating speed just becomes to become with flow, regulate flow can make rotating speed per minute several forward to 200 change between.
The axial displacement of above-mentioned glass marble (hereinafter to be referred as ball) is to produce like this: when the active force of fluid was not enough to raise ball, ball fell by gravity, and is tangent with hopper walls, and a circle is formed at the point of contact, and path is closed extremely.When the active force of fluid is enough to raise ball and opens passage, except that ball produced rotation effect, also because of the principle of continuity and the Bernoulli's theorem of fluid, ball is more than half of fluid dorsad, passage is very big, flow velocity is very slow, and pressure approaches atmospheric pressure, and meets the smaller part face to fluid, passage is relatively little a lot, flow velocity is very fast, and pressure is lower, for being defeated by atmospheric pressure.This pressure differential up and down forces ball to move down and closing passage.Pressure differential disappears thereupon this moment, so be returned to initial state again, fluid is raised ball once more, moves up and down endlessly so again and again.Under the same conditions, frequency becomes contravariant with electrode sensitive face to the distance between ball.Regulating this distance, can to make frequency remain on per second several conspicuous between tens hertz.
When moving the contact electrode sensitive area on the ball, because of time of contact very short, the momentum of ball is changed out bigger impulse force, can prevent and remove the fouling on the electrode sensitive face effectively, keeps constant surface state.In addition, this pulsation cleaning way is more energy-conservation, in water, is 10 millimeters to 25 millimeters solid glass ball for diameter, only 20 centimetres to 40 centimetres the height of water need be arranged, can reliably working.Ball is made hollow, then under the littler height of water, also can be worked.
Embodiment two, for sensitive area moulding, and the electrode that can not reprocess, its cleaning device is an example with ball bubble shape glass electrode (7), is described as follows:
The electrode that this type of sensitive area of all genus does not coincide with spherical spinner need only be changed the ball among Fig. 1 a spherical spinner (see figure 2) with the friction part (3) that coincide with the electrode sensitive face, just can solve.This rotor is to extend a hollow cylinder (8) on the main body of ball, will rub the part socket on it, and hollow institute capture power remains upwards facing to electrode the friction part.Also can not establish hollow and adopt other equivalent structure, for example the proportion of order friction part is light than spherical spinner, make whole centre of buoyancy that both are combined near friction part one end and center of gravity near the other end, can rely on buoyancy that the friction part is kept up equally.Difform electrode need only be used instead and its friction part that coincide, so can be general.When electrode limits when a kind of, then rub part and rotor can be made a hollow integral body.Ball bubble shape glass electrode sensitive area as thin as a wafer, damaged easily, should do the friction part with rubber, the strong material of plastics one class flexible resilient, its contact-making surface is made half concave spherical surface that coincide with the ball bubble, and can open some groove line or breach as required thereon, upgrade to strengthen friction and to be beneficial to fluid.On the friction part cap straight coupling and spherical spinner socket (stationary fit) are arranged.The installation of kind electrode cleaning device, starting and work are identical with embodiment one.Obviously, embodiment two also is applicable to the electrode of embodiment one, and embodiment one is the special case of embodiment two only, can simplify.
More than two embodiment be fluid and pass through from bottom to top, in fact whole device is inverted and is installed, and fluid is passed through from top to bottom, can also receive identical effect.When introducing fluid with siphon pipe; It is more convenient to be inverted installation.Embodiment one as the change on any structure, can directly not be inverted use.Embodiment two is inverted when using, and the combination of friction part and spherical spinner must be made the structure of centre of buoyancy near spheroid, and spheroid is remained upwards.
More than two embodiment all make, and in this institute laboratory, use, respond well.
Good effect of the present invention is: (one) is simple in structure, and element is few, and itself is not fragile, can adapt to the requirement in the medium-term and long-term continuous operation of fluid; (2) since the power resources of cleaning electrode in the friction of fluid, and frictional force mainly occurs in the very thin boundary-layer of rotor surface, and when load increased to the motionless rotor of fluid band, fluid just slipped over outside boundary-layer, it is excessive to be that driving force can not increase, thereby not fragile electrode; (3) need only prepare the friction part that some and difform electrode coincide one by one, just can accomplish general; (4) volume can be done very littlely, can also make one with electrode, can install in narrow space, thereby applicability is strong; (5) easily sealing is particularly suitable for using in the fluid that does not allow to leak with outside contamination; (6) make easily, production cost is low; (7) energy savings.
