The present invention is not changing under the prerequisite of grid weight and dimensions, by perpendicular rib both sides on grid, the object that flank reaches optimal design is set, on flank, have electric current to pass through to transmit electric current, the electric current that plate active material reaction is produced is more effectively pooled on perpendicular rib and conducts; Therefore guaranteed the response area of plate active material, the adhesion that has strengthened grid and active material and plate active material intensity, improved grid electric conductivity, guaranteed the requirement of the large electric current of electrokinetic cell run duration, high-multiplying power discharge.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is general structure schematic diagram of the present invention;
Fig. 2 is partial structurtes schematic diagram of the present invention;
Fig. 3 is B-B cutaway view in Fig. 2.
Embodiment
Below in conjunction with Fig. 1 to Fig. 3, illustrate the embodiment of the special-purpose grid of electrokinetic cell of the present invention.
As depicted in figs. 1 and 2, the special-purpose grid of a kind of electrokinetic cell, comprise grid body, the surrounding of described grid body is provided with frame, upper side frame 2 middle parts are connected with lug 1, described grid body is provided with the rib grid being comprised of transverse rod strip 5 and perpendicular rib 6 at scuncheon, described perpendicular rib 6 is along being vertically provided with several to two side-prominent flanks 7, and the upper outline line of described flank 7 rolls tiltedly (and the slanted angle of perpendicular rib effect between 30 degree to 60 degree is best) downwards.On perpendicular rib 6, increase to two side-prominent flanks 7, can strengthen the adhesion of grid and active material, guarantee the intensity of plate active material, and the oblique object of the downward inclination of upper outline line that makes flank 7 is to make active material on flank 7 produce potential difference from bottom to top, thereby making has electric current to pass through to transmit electric current on flank 7, the electric current that plate active material reaction is produced is more effectively pooled on perpendicular rib 6 and conducts, thereby realizes the requirement of the large electric current of electrokinetic cell run duration, high-multiplying power discharge.
Further, as shown in Figure 3, the sectional area of described flank 7 diminishes to both sides gradually by erecting rib, and the cross section of flank 7 is roughly isosceles trapezoidal structure, makes flank 7 have enough large sectional area, has guaranteed the response area of plate active material abundance.
Described flank 7 is sector structure, and the upper outline line of flank 7 is the circular arc line that downward lateral bend tilts like this, certainly, as further distressed structure, described flank 7 rectangular trapezium structures or described flank structure triangular in shape, now, the upper outline line of flank 7 is downward-sloping straight line.Above-mentioned its object of flank 7 structures is all to make active material on flank 7 produce potential difference from bottom to top.
On described left and right side frame 3, be also provided with outstanding to the inside flank, this flank is identical with the function of flank on perpendicular rib, can transmit electric current, and the electric current that plate active material reaction is produced is pooled on left and right side frame 3 and conducts, and finally flows to lug 1.
On described perpendicular rib 6, flank 7 is symmetricly set on perpendicular rib 6 both sides.And perpendicular rib 6 arranges a pair of flank 7 between two adjacent transverse rod strips 5.
The upper sideline of described upper side frame 2 upwards seamlessly transits the pecten sealing wire position to lug 1 dual-side.Shown in figure 1, this seamlessly transits structure and forms the arc transition line that connects upper side frame 2 upper sidelines and lug 1 dual-side, guarantees that in plate active material course of reaction, electric current more effectively collects, conducts to lug position.
The sectional area of described upper side frame 2 is increased gradually by two side direction lugs 1.Can more effectively collect like this current direction lug 1 on conduction left and right side frame 3.
The sectional area of described lower frame 4 is less than the sectional area of upper side frame 2 and left and right side frame 3.That is to say that lower frame 4 is thinner than upper side frame 2 and left and right side frame 3.This is because lower frame 4 plays the effect of strengthening pole plate intensity, does not participate in the one-tenth stream reaction of pole plate, so the sectional area of lower frame 4 is less than upper side frame 2 and left and right side frame 3, to reach the object that reduces material.
In addition, in the present embodiment, reduced the quantity of transverse rod strip 5 in grid, but the quantity that also should guarantee transverse rod strip 5 is no less than transverse rod strip quantity in conventional grid half, due to the not increase of quantity of perpendicular rib simultaneously, and increased flank on perpendicular rib, therefore, do not weaken the intensity of plate active material.
In sum, by enforcement of the present invention, do not changing under the prerequisite of grid weight and dimensions, by increasing the object that reaches optimal design with flank on grid, guaranteed the response area of plate active material, the adhesion that has strengthened grid and active material and plate active material intensity, improved grid electric conductivity, guaranteed the requirement of the large electric current of electrokinetic cell run duration, high-multiplying power discharge.
