Abstract
The utility model relates to a membrane pile gripping mechanism in an electrodialysis unit, which is composed of a decorative plate, a pressure plate and a pressure screw bolt. When the utility model is used, the bulges of the both ends of the pressure plate face to the side of a membrane pile, the pressure screw bolt is composed of a screw bolt and a casing tube with internal screw threads, and when the membrane pile is gripped tightly, the screw threads are screwed into the casing tube to save space. Parallel ripples which outwards bulge are arranged on the decorative plate, and the decorative plate plays the function of a supporting plate for the membrane pile.
Description
This case belongs to the clamp mechanism of the interior membrane stack of electrodialysis plant in the membrane separation technique field.Electrodialysis plant can be used for the desalination and the preparation high purity water of various bitters.
Membrane stack is the core component in the electrodialysis plant, is made up of a plurality of tabular widgets, must it be clamped reliably by clamp mechanism, guarantees its globality, guarantees that particularly the water of inside when work is non-leakage.
The clamp mechanism of prior art is made up of pressure strip and hold-down bolt two parts, is out of shape when exerting pressure for preventing pressure strip, and its two ends are bent into a projection to a side that deviates from membrane stack, have occupied certain space, and not attractive in appearance.
The purpose of this case provides a kind of pressure strip, the projection of the bending part at its two ends is towards membrane stack one side in use, and provide a kind of hold-down bolt, this hold-down bolt is made of the sleeve pipe of tool internal thread and common bolt, when clamping membrane stack, the unnecessary part of bolt screws in the sleeve pipe, and saves the space.A kind of decorative panel also is provided, the parallel ripple of oriented outer lug on it, its double simultaneously gripper shoe of doing membrane stack makes whole membrane stack be convenient to fix, and good looking appearance.
Accompanying drawing has been illustrated the embodiment of this case, existing adjoint narration embodiment.
The description of the drawings:
Accompanying drawing 1 is the schematic diagram of pressure strip and decorative panel.
Accompanying drawing 2 is schematic diagrames that hold-down bolt part sleeve pipe matches with bolt.
Accompanying drawing 3 is schematic diagrames that membrane stack matches with clamp mechanism.
Make pressure strip (1) and decorative panel (7) at first as shown in Figure 1, as shown in Figure 2, the method of nut (2) with welding or interference fit is fixed in the sleeve pipe (3), then as shown in Figure 3, the bossing at pressure strip (1) two ends is enclosed within the two ends of this membrane stack towards membrane stack (4) one sides, and sleeve pipe (3), bolt (5) and the pad (6) that will have nut (2) run through decorative panel (7) pressure strip (1) and membrane stack (4) and screw and get final product.
This clamp mechanism is simple, and is convenient and practical.
Claims (1)
- A kind of about the membrane stack clamp mechanism in the electrodialysis plant, constitute by decorative panel, pressure strip and hold-down bolt, the projection that the pressure strip two ends have bending to form, it is characterized in that pressure strip (1) in use its projection towards membrane stack (4) one sides, hold-down bolt is made up of sleeve pipe (3) and bolt (5), fixing nut (2) in the sleeve pipe (3), the parallel ripple of oriented outer lug on the decorative panel, its double simultaneously gripper shoe of doing membrane stack.
