Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.It should be noted that at this, the explanation for these embodiments understands the utility model for helping, but does not form restriction of the present utility model.
As shown in Figures 1 to 7, the utility model comprises plate body 1 and framework 2, described plate body 1 is rectangle, described framework 2 is quadrilateral frame body, described plate body 1 is welded on described framework 2, also comprise PP aft cover plate 3, described PP aft cover plate 3 is close to described plate body 1 two sides, and described PP aft cover plate 3 has pod apertures 31.PP aft cover plate 3 is isolation material, its effect is bucking current, on PP aft cover plate 3, the object of perforate is the position controlling electrolyte and the contact area of plate body 1 and the size of contact area and contact surface, controls the flow direction of electrolysis unit electric current, size and distribution situation further.
Specifically, the position that described pod apertures 31 is offered is PP aft cover plate 3 bottom 32, and described bottom 32 area accounts for 4/5 ~ 5/6 of whole PP aft cover plate 3 area.Because the electrochemical reaction initial stage electric current of aluminium foil after entering forming liquid is large, cause the electric current on plate body 1 top large, the electric current of bottom is little, because monoblock plate body 1 conducts electricity uneven.The object offering pod apertures 31 overcomes this defect, therefore suitably will increase the electric current of plate body 1 bottom, reduces the electric current on plate body 1 top.Therefore, pod apertures 31 is opened in the bottom 32 of PP aft cover plate 3, and the area of described bottom 32 accounts for 4/5 ~ 5/6 of whole PP aft cover plate 3 area.This structure can make the bottom of electrolyte contacts plate body 1, makes it conduct electricity.
Specifically, described pod apertures 31 is uniformly distributed on described bottom 32, and perforated area is by dredging to close from top to bottom.Pod apertures 31 distributes from top to bottom by dredging to close, can reach and the electric conductivity of plate body 1 is from top to bottom increased gradually, by defect that the electric current of plate body 1 is up big and down small before overcoming.
Specifically, the shape of described pod apertures 31 is circular, and diameter range is 8 ~ 10mm, and the sparse part in top and lower dense part all become matrix form to arrange.Perforate principle is that plate body 1 is reduced from top to bottom gradually with the contact area of electrolyte, according to this principle, the mode of convincing discharge orifice 31 by patient analysis just has a lot, such as, the shape of pod apertures 31 can be the regular shapes such as square, oval, triangle, also can be irregularly shaped; The selection mode of perforate size also has a lot, if perforate is little, so just reaching the object of the contact area controlling plate body 1 diverse location and electrolyte by controlling the number of openings, if perforate is large, just suitably can reduce the sum of perforate; The arrangement mode of pod apertures 31 also can be various, can arrange, also can be arranged in fish scale-shaped etc. in matrix form.
Specifically, described plate body 1 is spot welding with the welding manner of described framework 2, and some postwelding forms solder joint 4.Because electrolysis power is delivered on plate body 1 by framework 2, the conductive capability of plate body 1 therefore can be controlled by controlling plate body 1 and the contact position of framework 2 and the size of contact area.The utility model adopts spot welding mode plate body 1 and framework 2 to be linked together, and therefore can be controlled the conductive capability of plate body 1 by the quantity and position controlling the solder joint 4 that spot welding is formed.
Specifically, the distribution mode of described solder joint 4 on described framework 2 is dredged lower close on being.Because framework 2 is the rectangle framework of mating with plate body 1 size, during spot welding, by the welding of the surrounding of plate body 1 on the frame 2, therefore the position of solder joint 4 distributes along framework 2 frame.Because conventional conductive pole plate top electric current is greater than lower current, therefore, in order to make the conductive capability of plate body 1 upper and lower identical, the distribution density in solder joint 4 portion on the frame 2 should be less than the distribution density of solder joint 4 in framework 2 bottom.Concrete, the distribution mode at solder joint 4 sparse place of portion is on the frame 2 for distribute one along described framework 2 frame every 20cm, and the distribution mode of solder joint 4 at framework 2 lower dense place is for distribute one along described framework 2 frame every 5cm.Certainly, solder joint 4 is close under distributing and above dredging is principle, and the distance between concrete solder joint 4 can also be other, and this needs the size according to conductive plate and determines.
Specifically, the thickness range of described plate body 1 is 1 ~ 3mm, and length range is 1300 ~ 1400mm, and width range is 500 ~ 650mm, and the size of described framework 2 arranges and coordinates with described plate body 1.Preferably, the thickness of plate body 1 is 3mm, and length is 1325mm, and width is 550mm.The thickness of PP aft cover plate 3 is 8mm, and length is 1373mm, and width is 598mm.The distribution mode at solder joint 4 sparse place of portion is on the frame 2 for distribute one along described framework 2 frame every 20cm, and the distribution mode of solder joint 4 at framework 2 lower dense place is for distribute one along described framework 2 frame every 5cm.The diameter of pod apertures 31 is 10mm, and the distance between upper hole and hole is 125mm, altogether offers 2 row; Distance between mider hole and hole is 100mm, altogether offers 3 row; Under distance between not intensive portion Kong Yukong be 50mm, altogether offer 11 row.
Specifically, described PP aft cover plate 3 is PP plastic material, and described plate body 1 is steel plate.
