Three-layer co-extrusion electrodialysis partition plate layer
The utility model relates to a water treatment technical field, in particular to three-layer is electrodialysis baffle layer altogether.
The electrodialysis partition is one of essential accessories of an electrodialysis device, and the function of the partition is to keep a certain distance between a negative membrane and a positive membrane to form a dense-dilute compartment, ensure smooth water flow and conduction current and keep tightness. The common baffle is often fitted or bonded to a spacer mesh which serves to agitate the liquid and promote turbulence. The material used as the separator should have a certain chemical stability, and be resistant to acid and alkali corrosion. At present, the commonly adopted partition plate materials comprise insulating materials such as polyvinyl chloride, polypropylene, polyethylene and the like, and can also adopt rubber. The thickness of the separator varies from 0.5 to 2.0 mm. In terms of the flow pattern, there are two types, a loop and a non-loop.
There is following problem among the prior art, the seepage can hardly appear after the stack of baffle multilayer, and it is present that to tailor a frame in addition, forms one deck antiseep layer on attaching to the frame of baffle, increases the technology degree of difficulty and cost, perhaps directly scribbles one deck antiseep coating on the frame of baffle, can increase the technology cost, and the extravagant material of not good recovery.
Disclosure of Invention
Therefore, a three-layer co-extrusion electrodialysis partition layer is needed to be provided, the device reduces the difficulty and cost of the process through reasonable layout of each structure, and enables the product to be recycled, so that the effects of environmental protection and resource saving are achieved.
In order to realize the above object, the utility model provides a three-layer is electrodialysis baffle layer altogether, include baffle, water distribution runner, separate net and drain hole, a cavity has been seted up on the baffle, separate the net setting in the cavity, the water distribution runner is connected with the cavity, the drain hole runs through the setting on the baffle, and the drain hole part is connected with the water distribution runner, the baffle is the material layer altogether, the material layer altogether includes at least three-layer, separate the net setting on one of them layer on the material layer altogether. The setting of crowded material layer altogether makes the baffle can hug closely each other after stacking, just forms an antiseep circle naturally, does not remove the later stage and adds again, reduces the degree of difficulty and the cost of technology, and makes the product can retrieve and utilize, plays environmental protection resources are saved's effect.
Furthermore, the co-extrusion material layer comprises three layers, namely an outer layer, a middle layer and an inner layer, wherein the middle layer is positioned between the outer layer and the inner layer, and the separation net is arranged on the middle layer. The arrangement of the outer layer and the inner layer ensures the sealing performance when the partition plates are overlapped, and ensures that the middle layer can be subjected to double sealing.
Furthermore, the middle layer is a PP material layer, and the thickness of the middle layer is 0.3-1.2 mm; the outer layer is one of EVA, TPE and TPR, and the thickness is 0.1-0.3 mm; the inner layer is one of EVA, TPE and TPR, and the thickness is 0.1-0.3 mm. The use of multiple materials enables the baffle to adapt to different scenarios.
Furthermore, an arc-shaped flow passage is arranged on the water distribution flow passage, a through hole is formed in the middle of the arc-shaped flow passage, and the arc-shaped flow passage is divided into two different flow passages. The setting of arc runner makes liquid flow more smoothly, and the setting up of through-hole makes upper and lower floor flow more smooth and easy.
Furthermore, the two different flow channels are divided into an upper concave flow channel and a lower concave flow channel, and the upper concave flow channel and the lower concave flow channel are respectively arranged on the lower surface and the upper surface of the water distribution flow channel. The arrangement of the double-sided flow channel enables the liquid to smoothly flow on any side.
Different from the prior art, the technical scheme has the following beneficial effects:
the utility model discloses the baffle design is three-layer crowded material layer altogether, including skin, intermediate level and inlayer, when stacking the baffle, skin and inlayer between the adjacent baffle will laminate mutually and directly form an antiseep circle, need not remove in addition and tailor a frame, adhere to and act as one deck antiseep layer on the frame of baffle, perhaps directly scribble one deck antiseep coating on the frame of baffle, reduce the technology degree of difficulty and cost, make things convenient for material recycle, resources are saved.
