Abstract

The utility model relates to a homogeneous-phase electric dialyzer with an ion exchange membrane. In the utility model, a partition plate is of an elastic combined partition plate, namely, the partition plate is formed by that a middle plate and two side plates are stacked and fixedly connected; the two side plates have water flow channel orifices and middle compartments, and the water flow channel orifices and middle compartments are corresponding to the middle plate. The side plates are partially covered on water distributing and collecting orifices on the middle plate, thereby, when in use, the phenomena that the inner shade compartments are mutually mixed and outwards leaked caused by that a thin and soft inelastic ion exchange membrane of homogeneous phase is collapsed at the position of the water distributing and collecting orifices are avoided. The utility model has the advantages of higher separating efficiency and higher yield.

Description

Equality phase ionic exchange diaphragm electric dialyzer

The utility model relates to a kind of electric dialyzator, is a kind of homogeneous ion-exchange membrane electric dialyzator.

Electric dialyzator mainly is made up of amberplex, dividing plate, electrode weather board and clamping device, and dividing plate is for separating support framework and the water stream channel between film and the film in the electric dialyzator.Dividing plate is generally made by the polypropylene hardboard, there is even number water stream channel mouth at the two ends of dividing plate, there is a compartment centre of dividing plate, extrude net in the heat seal of compartment place or bonding one or more layers plastics, or plastic window gauze, or plastics strand knitmesh, or plastics fish scale net, half number at dividing plate two ends separately the water stream channel mouth and intermediate compartment between the cloth inlet is arranged, the cloth inlet is generally slot type, or singly turns formula, or breakdown formula, or the net formula, dividing plate is generally made of the polypropylene hardboard, spreads with amberplex in bulkhead sides.

This dividing plate in use, especially the homogeneous ion-exchange membrane phenomenon that very easily occurs subsiding at cloth inlet place, cause inner deep or light compartment to leak mutually, this in addition dividing plate is harder, very easily leak outside, cause the separative efficiency of electric dialyzator to reduce thus and yield not high, this for the purification in chemical industry, medicine and the food service industry, separates that to reach process such as concentrated all be fatal defective.

Dividing plate external at present and the homogeneous ion-exchange membrane adapted is an elastic baffle, net formula cloth inlet embedding support chip, this dividing plate manufacturing, requirement on machining accuracy are very high, poor slightly as crudy, not only can not eliminate inside and outside leakage, and can aggravate, therefore this dividing plate is not suitable for promoting the use of in China.

The purpose of this utility model is to provide a kind of homogeneous ion-exchange membrane electric dialyzator, by changing the structure of its median septum, eliminates inside and outside leakage problem, and the manufacturing use is all simple and convenient, thereby improves the separative efficiency and the yield of this electric dialyzator.

The purpose of this utility model is achieved in that by homogeneous ion-exchange membrane, dividing plate, in the homogeneous ion-exchange membrane electric dialyzator that electrode weather board and clamping device are formed, dividing plate is by intermediate plate and biside plate totally three layers of elasticity combination barrier of making of elastomeric material of forming, respectively there is even number water stream channel mouth at the two ends of the intermediate plate of middle one deck, there is a compartment centre of intermediate plate, wherein half number separately the water stream channel mouth and intermediate compartment between the cloth inlet is arranged, the cloth inlet is made up of at least one tank, tank and water stream channel mouth are not linked up, can link up with compartment, also can not link up.Have on the side plate at intermediate plate two sides places with intermediate plate on corresponding water stream channel mouth and intermediate compartment, biside plate part drape inlet, the superimposed formation combination barrier that connects firmly of intermediate plate and biside plate, one deck plastic wire at least that tiles at the intermediate compartment place of dividing plate, plastic wire can tile or heat seal or be bonded in the intermediate compartment place.

Intermediate plate and side plate are with making as rubber or polyvinyl acetate, and the shape of its water stream channel can be rectangle, triangle, circle or polygon.

A kind of homogeneous ion-exchange membrane electric dialyzator that the utility model provides, owing to adopt the elasticity combination barrier, the side plate of intermediate plate both sides play supporting role to soft thin and inelastic homogeneous ion-exchange membrane, thereby avoided that homogeneous ion-exchange membrane subsides at the cloth inlet place of intermediate plate when using existing dividing plate, and cause inner deep or light compartment to leak mutually, owing to adopt elastic baffle, make between plate and the plate in addition, have good sealing property between plate and the film.Therefore, improve the separative efficiency of electroosmosis board device, guaranteed the quality and the yield of desalination (or concentrate, separate, purify).

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing

Embodiment 1:

As shown in Figure 1, respectively there are four rectangle water stream channel mouths at the two ends of rubber system intermediate plate 1.(omitting among second half intermediate plate figure of symmetry).In the centre of intermediate plate 1 rectangular compartment 15 is arranged, between compartment 15 and mouth 12 and compartment 15 and mouth 14, respectively have and be three cloth inlets 16 that the shape that scatters extends to compartment, in the both sides of intermediate plate 1 a rubber system side plate 2 is arranged respectively, position and intermediate plate 1 suitable for reading 11 are arranged on the side plate 2, mouth 12, mouth 13, the mouth 21 of mouth 14 and compartment 15 correspondences, mouth 22, mouth 23, mouth 24 and compartment 25, and mouth 22, mouth 24 and compartment 25 are greater than mouth 12 corresponding on the intermediate plate 1, mouth 14 and compartment 15, so that the cloth inlet exposes side plate 2, each bonding plastics plastics strand knitmesh 26 on the compartment 25 of biside plate 2.

Implement side 2:

As shown in Figure 4, water stream channel mouth 31, mouth 32, mouth 33, mouth 34 are arranged on the polyvinyl acetate system intermediate plate, between mouth 32 wherein and the compartment 35 and mouthfuls 34 with compartment 35 between being three cloth inlets 36 and compartment 35 communications that the shape that scatters is arranged, two layers of plastics plastics strand of tiling knitmesh 37 on intermediate plate 3, other structure is identical with embodiment 1.
