The utility model compared with the prior art, has the advantages that
The nickel electrowinning diaphragm of the utility model passes through preceding diaphragm cloth, metacneme cloth, two pieces of side diaphragm cloth, bottom diaphragm cloth composition
The diaphragm bag structure of original ordinary flat is re-designed as rectangular parallelepiped structure by bag body, is especially advantageous for staff and is interted cathode
Working efficiency greatly improved in plate, reduces the case where anode and cathode connects electrical breakdown diaphragm bag, reduces the loss of diaphragm bag, from
Production cost has been saved in whole production.By pasting fitting lining in suture, diaphragm cloth before increasing, metacneme cloth, side every
The stiffness of film cloth, the more preferable rectangular parallelepiped structure for keeping diaphragm bag are not only convenient to staff and intert cathode plate, reduce yin
Anode connects the case where electrical breakdown diaphragm bag, and is bonded the power line for serving as a contrast and can obstructing cathode board ends, prevents cathode plate edge
Tie grain.
The bottom diaphragm cloth of the utility model is structure as a whole with preceding diaphragm cloth, metacneme cloth, and not only production is simple, but also subtracts
Lack stylolite, reduced process, also prevents sepage.
The width that the fitting lining of the utility model is pasted on the diaphragm cloth of side is of same size with side diaphragm cloth, by entire side
The fitting of diaphragm cloth, and is bonded with preceding diaphragm cloth and metacneme cloth respectively, and be fitted in side diaphragm cloth, preceding diaphragm cloth and after every
Fitting on film cloth serves as a contrast to form U-shaped fitting lining.And the fitting lining of the diaphragm cloth fitting one fixed width bottom of at, due to general diaphragm bag
Width is 980mm, and cathode board width is 880mm-900mm, before being only pasted on diaphragm cloth, metacneme cloth and bottom diaphragm cloth
Fitting lining width be 60mm-70mm, can effectively stop the power line of cathode board ends, prevent cathode plate edge knot grain.
The opening two sides of the bag body of the utility model are respectively arranged with opening supports block, and opening supports block can be used for strutting bag
Mouthful, interspersed convenient for cathode plate, being not susceptible to anode and cathode, even electricity burns bag body.
The suture of the utility model is bonded by epoxy resin or polytetrafluoro lotion with lining is bonded.Epoxy resin or poly- four
The plastering agent of fluorine emulsion can not only paste fitting lining, can also block the pin hole of tape edge formation, prevent leakage.
Preceding diaphragm cloth, metacneme cloth and the first side diaphragm cloth, second side diaphragm cloth suture and of the utility model
The viscous suture of the suture of the lower end of side diaphragm cloth, the lower end of second side diaphragm cloth and bottom diaphragm cloth is 3-7 times, and suture it
Between between be divided into 2mm.Suture number cannot be very few, is otherwise not connected firmly, with the corrosion easy fracture of catholyte, influence using
Service life.Suture number cannot be excessive, and otherwise the tape edge service life is far more than the service life of bag body, causes waste silk thread.
It turns up and sutures to form the first diaphragm cavity, metacneme with preceding diaphragm cloth in the upper end of the preceding diaphragm cloth of the utility model
The upper end of cloth turns up and sutures to form the second diaphragm cavity with metacneme cloth, and suture is 2-4 time, between suture between be divided into
2mm.If suture number is less than 2 times, bag body inner cathode liquid heavier-weight, broken string easily occurs, diaphragm bag is caused to fall into anolyte
In, suture number is more than 4 times, although tape edge intensity is secured, the tape edge service life is far more than the service life of bag body, causes to waste
Silk thread.In first diaphragm cavity and the second diaphragm cavity to inject catholyte, starting sheet then is installed, prevent diaphragm bag with
Starting sheet contact, which is powered, punctures diaphragm bag.
