Referring to Fig. 2 and Fig. 3, partition 1 is the rectangular slab that quadrangle is in rounded corner setting, and the middle part is provided with perforative for water body
The hollow hole 11 flowed through.Be covered with amberplex 3 at hollow hole 11, amberplex 3 divide for cation-exchange membrane and yin from
Two kinds of proton exchange, can respectively in water body cation and anion play barrier action.Ion in the present embodiment is handed over
It changes film 3 to be fixed at the hollow hole 11 of partition 1 by the pressing plate 4 and fixing bolt 5 of annular, and the fixing bolt 5 selected is equal
For countersunk head hexagon socket head cap screw.
Referring to Fig. 3, the periphery of hollow hole 11 is provided with tongue and groove 2, and hollow hole for installing the side of amberplex 3
The first supportive grid 6 is covered at 11.First supportive grid 6 is in Cellular Networks trellis, and periphery is fixed on the side wall of hollow hole 11.
The width of pressing plate 4 is equal to the width of tongue and groove 2, and thickness is equal to the depth of tongue and groove 2, and is provided on pressing plate 4 for supporting with first
The second supportive grid 7 that grid 6 cooperates.Second supportive grid 7 is equally in Cellular Networks trellis, and the inner edge of periphery and pressing plate 4 is solid
Fixed connection.Due to the presence of the first supportive grid 6 and the second supportive grid 7, amberplex 3 is significantly greatly increased and has born hydraulic pressure work
Ability has dispersed the tension of 3 periphery of amberplex being subject to, has been used for a long time and is less prone to deformation failure.
Referring to Fig. 3, the equidistantly distributed on pressing plate 4 of fixing bolt 5 covers amberplex 3 when installing amberplex 3
It is placed at the hollow hole 11 on partition 1, gland pressing plate 4 makes pressing plate 4 be caught in tongue and groove 2.Amberplex 3 is clamped in the first support
Between grid 6 and the second supportive grid 7, while its periphery is clamped between pressing plate 4 and the bottom wall of tongue and groove 2, is then successively revolved
It is firm that tight each fixing bolt 5 can install amberplex 3.
Setting is provided in the long side of pressing plate 4 for the ease of quickly being positioned when installation pressing plate 4 referring to Fig. 3 and Fig. 4
There is locating convex block 42, and be provided with locating convex block 42 at two in each long side, the locating convex block 42 in the long side of two sides is in each other
Axial symmetry setting.Corresponding position is provided with the locating slot 21 being caught in for locating convex block 42 on the side wall of tongue and groove 2.Pressing plate 4 is installed
When, the alignment of pressing plate 4 can be fast implemented by locating convex block 42 and locating slot 21.Locating convex block 42 is caught in locating slot 21,
Can carry out Primary Location so that be tightened bolt 5 when, pressing plate 4 is not easy to loosen.
Referring to Fig. 3 and 4, it is also evenly distributed with dotted anti-sliding burr 22 on the bottom surface of tongue and groove 2, further increases ion
Contact area between exchange membrane 3 and pressing plate 4 increases the fixed fastness to amberplex 3, so that amberplex 3 weeks
The even tension that edge is subject to everywhere is not easy to loosen in use.
Referring to figure 5 and figure 6, the bottom surface of pressing plate 4 is provided with elastic cushion 41, and elastic cushion 41 is rubber layer in the present embodiment.Bullet
Property pad 41 increases the laminating degree between pressing plate 4 and amberplex 3, increases the fixed fastness to amberplex 3, and
It is contacted so that pressing plate 4 is not direct with amberplex 3, it is not damaged that protection amberplex 3 is conducive in installation process.
Referring to figure 5 and figure 6, the corresponding seamed edge of the arc-shaped transition of the bottom wall of tongue and groove 2 and side wall junction, pressing plate 4 falls in circle
Angle setting, increases the cooperation compactness between pressing plate 4 and tongue and groove 2, and be not easy to cause amberplex 3 when gland pressing plate 4
Every damage.
Working principle is as follows:
In EDI device on certain block partition 1 amberplex 3 deformation, damage when, by corresponding partition 1 dismantle take out, to from
Proton exchange 3 is replaced.Each fixing bolt 5 is successively unscrewed, amberplex 3 can be removed by removing pressing plate 4.
Again new amberplex 3 is covered at hollow hole 11, makes the locating convex block 42 on pressing plate 4 to 2 side wall of tongue and groove
On locating slot 21, pressing 4 inlay card of pressing plate in place.At this point, the dotted anti-sliding burr 22 on 2 bottom wall of tongue and groove squeezes 4 bottom surface of pressing plate
On elastic cushion 41 so that the periphery of amberplex 3 is clamped between pressing plate 4 and the bottom wall of tongue and groove 2.It successively screws each solid
Determine bolt 5 so that the first supportive grid 6 at 1 hollow hole 11 of the second supportive grid 7 and partition on pressing plate 4 be matched for clamping tightly from
Proton exchange 3 so that 3 uniform throughout stress of amberplex, in less later period use process because of factors such as heated, hydraulic pressure caused by
Deformation etc., conducive to reducing the replacement frequency of amberplex 3, prolonging its service life.
Above-mentioned specific embodiment is only the explanation to the utility model, is not limitations of the present invention, this
Field technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification,
But as long as all by the protection of Patent Law in the scope of the claims of the utility model.
