Abstract
The utility model relates to a rubber spacer of an ion film hydroelectric bath. The local part of the sealing surface of the rubber spacer is provided with protruding sealing lines. The rubber spacer is a rectangular frame of which the cross section is a rectangle. The sealing surface contacted with the rubber spacer and an ion film is provided with high and low sealing lines of which the cross section is triangle. The low sealing line is the same as that in the prior art. The cross section of the high sealing line is a triangle, the height of the triangle is from 1.0MM to 1.5MM, and the bottom length of the triangle is from 2MM to 4MM. Three to four high sealing lines are arranged, and the distance from the innermost high sealing line to the inner frame edge of the rectangular frame is from 7MM to 12MM. The sealing surface of the utility model, which is in contact with the ion film, is provided with high and low sealing lines. Under installation pressure, two lines of sealing are generated. The low sealing line forms a line of sealing, and the high sealing lines squeeze the ion film locally and excessively to form the other line of sealing. The line of sealing, which is formed by excessive squeeze, can ensure that the ion film is always sufficiently pressed in the process of using, which prevents the ion film from generating pore space because materials are etched. No leakage can occur, and the reliability of the sealing is ensured.
Description
Technical field
The utility model relates to a kind of ion-exchange membrane electrolyzer rubber sheet gasket, the potted line on particularly a kind of ion-exchange membrane electrolyzer rubber sheet gasket and the contacted trim of ionic membrane.
Background technology
Ion-exchange membrane electrolyzer is formed by pole plate, ion-exchange membrane electrolyzer rubber sheet gasket and ionic membrane are overlapping successively.Pole plate is to be made by metallic substance, and ionic membrane is to be the superpolymer diaphragm of skeleton with the polytetrafluoroethylene wire cloth, and the ion-exchange membrane electrolyzer rubber sheet gasket is the rubber sheet gasket that shape and size match with pole plate.The ion-exchange membrane electrolyzer rubber sheet gasket is that cross section is the orthogonal rectangle frame, and the both sides of rubber sheet gasket have respectively and pole plate and the contacted trim of ionic membrane, are leg-of-mutton potted lines with being evenly equipped with cross section on the contacted trim of ionic membrane.In the prior art, be identical, contour with the triangular cross section of potted line on the contacted trim of ionic membrane, the height of cross-sectional triangle is 0.5～0.7 millimeter, and end length is 1.5～2 millimeters.During with this ion-exchange membrane electrolyzer rubber sheet gasket and pole plate and ionic membrane assembling electrolyzer, pole plate, the overlapping successively component units electrolyzer of rubber sheet gasket and ionic membrane, pressure with regulation is pressed together a plurality of unit electrolytic baths, because the potted line of this ion-exchange membrane electrolyzer rubber sheet gasket and the contacted one side of ionic membrane is contour, so the squeeze to ionic membrane is uniform, it is reliable using sealing in a short time, but after one period duration of service, owing to ionic membrane inner structure material is subjected to etch to produce hole, above-mentioned rubber sheet gasket is not enough to the sealing force that produces the hole ionic membrane, so often leaking from hole through medium after the regular hour.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, propose a kind ofly can produce excessive extruding to ionic membrane, thereby can cut off the hole that ionic membrane in use produces, make the reliable all the time a kind of ion-exchange membrane electrolyzer rubber sheet gasket that outstanding potted line is arranged in the trim part of sealing effectiveness.
The utility model is realized with the following method.
This is a kind of, and the ion-exchange membrane electrolyzer rubber sheet gasket of outstanding potted line is arranged in the trim part is that cross section is the orthogonal rectangle frame, the both sides of ion-exchange membrane electrolyzer rubber sheet gasket have respectively and pole plate and the contacted trim of ionic membrane, with on the contacted trim of ionic membrane height is arranged, low two kinds of potted lines, low potted line is that the many sliver transvers sections identical with potted line in the prior art are leg-of-mutton potted lines, the height of low potted line cross-sectional triangle is 0.5～0.7 millimeter, end length is 1.5～2 millimeters, between low potted line cross section being arranged is leg-of-mutton high sealing line, the height of the cross-sectional triangle of high sealing line is 1.0～1.5 millimeters, end length is 2～4 millimeters, the high sealing line has 3～4, and the distance of edge is 7～12 millimeters in the interior high sealing linear distance rectangle frame.
High and low two kinds of potted lines are arranged on the contacted trim of the utility model and ionic membrane, under the pressure of afore mentioned rules, can produce different two seals, low potted line form together with prior art in identical sealing, the high sealing line ionic membrane is produced local excessive extruding, form the sealing of another road, this form by excessive extruding seal ionic membrane capable of blocking is produced by etch because of material hole together, guarantee that sealing is reliable.
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the front view of not contour potted line ion-exchange membrane electrolyzer rubber sheet gasket;
Fig. 2 is the A-A synoptic diagram of Fig. 1.
Embodiment
Fig. 1, among Fig. 2, this is a kind of, and the ion-exchange membrane electrolyzer rubber sheet gasket of outstanding potted line is arranged in the trim part is that cross section is an orthogonal rectangle frame 1, the both sides of ion-exchange membrane electrolyzer rubber sheet gasket have respectively and pole plate and the contacted trim 2 of ionic membrane, 3, with on the contacted trim of ionic membrane height is arranged, low two kinds of potted lines 4,5, low potted line is that the many sliver transvers sections identical with potted line in the prior art are leg-of-mutton potted lines, the height of low potted line cross-sectional triangle is 0.5～0.7 millimeter, end length is 1.5～2 millimeters, between low potted line cross section being arranged is leg-of-mutton high sealing line, the height of the cross-sectional triangle of high sealing line is 1.0～1.5 millimeters, end length is 2～4 millimeters, the high sealing line has 3, and the distance of edge is 7～12 millimeters in the interior high sealing linear distance rectangle frame.
