Description
53~
~ he present invention pertains to electrolytic filter pre 9 9 cells. More particularly, the present invention pertains to cell frameQ for electrolytic filter press cell~. Even more particularly~ the present invention pertain~ to cell frames for bipolar electrolytic filter presc cells.
A~ i~ known to tho~e skilled in the art, a cell frame ¢ompri~e~ the basic rep~at unit in an electrol~tic filter pre~
cell. ~he cell frame functions a~ a separator or barrier between the anode of one cell and the cathode of the adjacent cell. A linear serie~ of cathodes, anode3 and interpo~ed cell frames con~titute~ a filter pres~ cell, in toto.
~ he prior art i9 replete with a wealth of technolo~y respecting filter pre3s cell~. Generally, howeYer, the prior art has paid a great deal of attention to electrode construc-tion, diaphragm materials and the like. On the other hand, little attention has been directed to the cell ~rame and means and methods for improving ~ame In U.S. Patent No. 3,836,448 there i8 disclosed a frame for a filter press cell which is di~ided into an upper zone and a lower zone. ~he upper zone i9 u~ed to collect the gase~ evolved during the electrolytic proce~s conducted in the lower zone. A plurality of apertures are formcd in the ~rame structure to provide communication between the two zones. This reference, also, teaches the neces~ity of ~eparate frame~ for the cathode and anode, as well as the need for the frames to be free o~ electrical insulating partitions. It is to be appreciat~d that the ~rame ~truoture is complex in that separate frame~ for the anode and cathode must be provided~ Al~o, the need to be free of electrical in~ulating partitions requires ~eparate structure therefor. This renders such stru¢ture expensive to manufacture.
Al30, U.S. Patent No. 3,252,88~, teaches a cell frame ~ .

1~83S~l for an electrolytic diaphragm cell. ~he reference teaches laterally spaced outlet~ ~or the gase~ evolved duri~g the electrolytic process. According to this reference, however, the diaphragm mu~t occupy substa~tially the entire space within the frame. ~hus, the frame cannot be utill~ed ln an electrolytic process which doe~ not utilize a di~phragm or where the diaphragm does not oceupy the entire space within the frame. ~hi~ negates any concept of a universally employable cell frame.
Other prior art background material can be found in U.S. Patent Nos. 3,856,652; 3,B55,104; 2,522,681; 1,366,090 and 3,647,672.

According to another embodiment, the present invention further includes improved m~ans for sealing and handling the frame~ hereof.
lhe embodiment~ of the invention will now be de~cribed in a non-limiting way with reference to the appended drawing in which:
FIG. 1 i~ a front elevational view of an electrolytic filter pre~s cell frame in aceordanc0 with the present invention, and FIG. 2 i~ a cross-~ectional view of the electrolytic filter pre~s cell frame of ~IG. 1 taken along the line 2-2 thereof.
With reference to the drawing, there is depicted ~ .
therein a bipolar electrolytic filter pres~ cell frame, generally indicated at 10. The frame comprise~ a first or lower section or zone 12 a~d ~econd or upper ~ection or zone 14. ~he lower zone 12 define~ the electrode area where the electrolytic solution i~ electrolyzed and the upper zone define~
the gas collection or disengagement area.
With more particularity, the cell frame 10 compri~es an integral unit which is injection molded or likewise formed from a sy~thetic re~inous material which i9 compatible with the electrolyte~, ~uch as filled or unfilled polypropylene.
The frame is molded ~uch that there i~ provided a 1a~83~3~L
` .:
peripheral rim 16 extendi~g therearound and a rece~ed central barrier or web 18.
The area of the frame extending downwardly from the top of the web 18 defines the lower zone of the frame.
A~ clearly shown in FIG. 2, the central barrier 18 compri~es a ~-shaped me~ber 20 having a linear ~ection 22 and legs 24, 26 extending laterally therefrom. One leg 24 is a~sociated with the anode ~ide of the fra~e. The other leg 26 is as~ociated with the cathode side of the frame. Each 1~ leg 24, 26 i~ provided with a plurality o~ exhau~t ports 23, 25, respectively, which provide ga~ disengagement mean~ in a manner to be described ~ubsequently The central barrier ~ection 22 is p~rovided with a plurality of aperture3 28. The apertures 28 receive bipolar connectors 30 therethrough. ~lthough any bipolar connector can be effectively u~ed herein, the central barrier 18 i~

As i~ known to tho~e skillbd in the art, the bipolar co~nectors 30 support the anode ~2 and the cathode 34. Thus, the space between the anode 32 and the section 22 de~ine~ the anolyte compartment. '~he ~pace between the cathode ~4 and the section 22 define~ the catholyte compartment. It should be noted with re~pect hereto that if conventional electrode3 are deployed, then a plurality of ~upport nubs 36 can project outwardly from the barrier to additionally ~upport the electrodes. ~he ~ub~
36 are generally formed integrally with the barrier section 22 and project laterally outwardly there~rom and ~ub~tantially perpendicular thereto The use of ~pport nubs is more particularly described in cope~ding Patent Application Serial No. 242,5l9, ~iled Dece~ber 22, 1975, and entitled "Electrode Support for Filter Pre~s Cell~".

~he upper zone 14 compriRes a plurality bf chambers or internal headers 44, 46, 48. ~he chamber~ communicate~ with either the anolyte or catholyte ~ide of the lower zone 12 via apertures 23 or 25. A~ ~hown in the drawing, the headers 44 and 48 communicate with the anolyte ~ide and the header 46 communicates with the catholyte ~ide.
The means (not shown) are connected with the chamber~
at the end of the filter pres~ module for withdrawing the gases.
~he panel is extremely efficacious in asbe~tos dia-phragm cells since it provide~ a ~pace above the diaphragm for diversion of the gases to upper zone 14. Diver~ion of the ga~e~, in this manner, deoreases electrolyte ~urbulence at the upper edge of the diaphragm thereby increasing it~ operating or u~eful li~e. ~he ga~e~ generated travel upwardly through apertures 23, 25, a~d into the upper zone.
The frame 10 include~ header~ 50, 52 di~po~ed at the bottom thereof. ~ach of the headers include~ an opening 5~, 56, re~pectively, which communicate~ with internal bores 58, 60.
~he internal bores are ~maller in diameter than their associated opening~ 54, 56 to minimize current leaXage between cells through the electrolyte. One of the bore~ 58 or 60 opens into the . .. . . ..

As hereinbefore noted the central barr~er io recessed within the peripheral rim 16. By providing the recessed confi-guration the ~upport grid o~ a depo~ited diaphragm can be mounted to the frame with the support being disposed within the rece~s of the panel. The depo~ited diaphragm can be ~ecured to the barrier through pins inserted into corner apertures 62.
polymeric sheet diaphragm or separa~or can also be used herein.
In such instan~e sealing i~ achieved at the peripheral rim and between the panel and pres~ure bar. In order to prevent di~tor-tion caused by the gases generated on the oathode side of the cell frame and to facilitate withdràwal of the gases, and to insure ~ealing at the upper edge of the separator, the prese~t invention may further include a pre~ure bar 64. ~he pressure bar 64 extends acro~ the cell ~rame 10 within the reces~ed portion thereof, The use of a pres~ure bar is more particularly described in copending Canadian Patent Application Serial No~
2s2,497 filed May 13, 1976, and entitled "Electrol~tic Filter Pres~ Cell Framé".
As shown in the drawing, mounted on each lateral side of the frame 10 are handles 66, 68. Each handle includes a shoulder 70, 72. ~he shoulder portion of the handle~

Di~po~ed on each lateral ~ide or face of the frame -30 is a pair o~ laterally extending projections 74, 76, 78 and 80, respectively ~he projection~ are dispo~ed above and below the handle~ 66, 68 a~ show~. Prefer~bly, the projeotions have .
~33531 throughbore~ 82 extending therethrough.
~ he projections 74, 76, and 80 ~upport the protection rods (not shown) of the filter cell ~nd which extend through the bore~ 82. A~ i9 known to tho~e skilled in the art the protection rods are employed to prevent the po~sible opening of the press in the event of hydraulic failure. ~he rod, al90, holds the frame together in the cell when the press i~ broken for removing a failing frame or ~eparator.
As shown in FIG. 19 an aperture 84 i~ pro~ided above ~0 the upper zone 14. The aperture 84 i~ utilized to li~t the frame 10 during assembly of the filter pres~ cell module.
Although not shown in the drawing, the frame 10 contemplates the ~ealing thereof with a ga~keting secured to the frame about the periphery thereo~. Separate gaskets are deployed about the headers. ~he peripheral ga3keting is provided on both sides of the ~rame.
It is to be appreciated that the present invention provides an automatic separation of product~, and i~ extremely efficaciou~ in the production of chlorine and caustic by brine ' eleotroly~is.
