Description
Technical field
The present invention relates to a kind of a bipolar type ion-exchange membrane electrolyzer negative electrode rubber sheet gasket, the groove frame face that particularly a kind of a bipolar type ion-exchange membrane electrolyzer negative electrode rubber sheet gasket contacts with the groove frame.
Background technology
The ionic membrane method alkali-chloride electrolysis tech has advantages such as occupation area of equipment is little, product concentration is big, energy consumption is little, pollution-free, is the state-of-the-art chloric alkali electrolysis technology of using both at home and abroad at present and developing.Ionic membrane method alkali-chloride electrolysis tech core is an ion-exchange membrane electrolyzer; Ion-exchange membrane electrolyzer is made up of three parts; Be cathode and anode groove frame, as the cathode and anode rubber sheet gasket and the ion mould of sealing member; Above-mentioned a few part constitutes unit groove, and with adjacent some unit grooves composition electrolyzer under extruding.The a bipolar type ion-exchange membrane electrolyzer of Japan Asahi Chemical Industry and China blue star company Application and Development is the ion-exchange membrane electrolyzer model that technology is more advanced both at home and abroad, application is the most general, and it represents the developing direction of ion-exchange membrane electrolyzer.Energy-conservation for further, above-mentioned producer develops and has used a bipolar type ion-exchange membrane electrolyzer of film pole span.The a bipolar type ion-exchange membrane electrolyzer of film pole span be that negative electrode frame face inside circumference at electrolyzer has added high 0.45 millimeter, the wide 5 millimeters boss that top layer nickel plate and lower floor's nickel screen are formed by one of a bipolar type ion-exchange membrane electrolyzer significant improvement structurally of big pole span; The cross section of boss is a rectangle; To reduce polar moment, reach the power saving purpose.
In the prior art; The negative electrode rubber sheet gasket of using with the cathode can frame of above-mentioned film pole span is the rectangle frame of a specification for 3 millimeters of long 2400 * wide 1200 * fabric width, 35 * thickness; And with the contacted groove frame of the trim of cathode can frame face on be evenly equipped with trapezoidal potted line, play sealing with cathode can frame cohesive force and prevent to be extruded outside the groove to increase interior depressing.Because the negative electrode rubber sheet gasket is a uniform thickness, therefore be tiled in the cathode can frame face that inside circumference has boss, can receive at the boss position than the bigger pressure of other part negative electrode rubber sheet gasket, squeeze bad with the ionic membrane that links to each other the negative electrode rubber sheet gasket easily.Because the negative electrode rubber sheet gasket is not installed spacing mark, therefore be difficult to the negative electrode rubber sheet gasket is assemblied on the tram of in the cathode can frame, extending 3 millimeters simultaneously.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency; Propose a kind of a bipolar type ion-exchange membrane electrolyzer negative electrode rubber sheet gasket of new film pole span of and cathode can frame boss position corresponding construction, this structure also helps the negative electrode rubber sheet gasket is assembled in the cathode can frame by technical requirements on 3 millimeters the tram.
The present invention realizes with following method.
At negative electrode rubber sheet gasket and cathode can frame contact surface inside circumference with the negative electrode rubber sheet gasket of original uniform thickness by the specific standard size of cathode can frame boss with reduced thickness; Form the decline step; The width of decline step is width+3 millimeter of cathode can frame boss, and it highly is the height of boss.The film polar moment ion-exchange membrane electrolyzer negative electrode rubber sheet gasket that position limiting structure is installed is promptly arranged; It is the rectangle frame rubber sheet gasket; It is the groove frame face that matches with the cathode can frame that the negative electrode rubber sheet gasket has a side; On the groove frame face, along on the groove frame face at groove frame face inside circumference place the decline step being arranged, the following folding face and the step surface of decline step are perpendicular, and it is the trapezoid potted line that the surplus part of negative electrode rubber pad film trap frame face is evenly equipped with the cross section.
On the decline step of inside circumference reduced thickness of the present invention and the trim of used groove frame, match along the square-section boss on the trim inside circumference place trim; The height of decline step equates with the height of boss, and the width of decline step is width+3 millimeter of cathode can frame boss.
During use; When on above-mentioned cathode can frame, sealing with the negative electrode rubber sheet gasket; On the groove frame, pave the present invention; Be buckled in decline step of the present invention on the boss of above-mentioned film pole span groove frame, clamp adjacent above-mentioned film pole span groove frame after, inside circumference of the present invention can stretch out 3 millimeters of adjacent rectangle electrolyzer frame inside circumferences.
The present invention has the decline step that matches with the boss of film pole span groove frame; The decline step can be used as the installing and locating part; On the groove frame, pave the while of the present invention, be buckled in decline step of the present invention on the boss of above-mentioned film pole span groove frame, make the present invention be easy to be laid on the negative electrode rubber sheet gasket; After clamping adjacent above-mentioned film pole span groove frame; Negative electrode rubber pad film trap frame face can not receive bigger local pressure makes sealing reliable, simultaneously, at the inside circumference of negative electrode rubber sheet gasket 3 millimeters of the adjacent rectangle of stretching out electrolyzer frame inside circumferences is arranged.
Below in conjunction with accompanying drawing, the present invention is done explanation further.
