Description

Technical Field

[0001] The utility model relates to the technical field of partitions, and specifically relates to a micro electro-dialysis partition with a loop Background Technique

[0002] Dialysis refers to the phenomenon that solutes in a solution pass through a semi-permeable membrane. The driving force of natural dialysis is the concentration difference of solutes on both sides of the semi-permeable membrane. Under the action of a direct current electric field, the phenomenon that ions pass through a selective ion exchange membrane is called electro-dialysis. The research on electro-dialysis technology began in Germany in 1903, and industrialization began in the 1950s. Electro-dialysis technology is applicable to the intermediate water treatment in industries such as petroleum, electronics, medicine, chemical industry, thermal power generation, food, beer, beverage, printing and dyeing, and painting. It is also applicable to special separation fields such as concentration and purification of amino acids, xylo-oligosaccharides, proteins, milk, betaine, and pharmaceutical intermediates.

[0003] According to a publicly announced electro-dialysis partition (publication number: CN217732756U), in the above application, by setting a partition body, the partition body includes an electro-dialysis plate and a frame. The outer side wall of the electro-dialysis plate is fixedly connected to the inner side wall of the frame. The electro-dialysis plate is composed of a first anion membrane layer, a first cation membrane layer, a second anion membrane layer, and a second cation membrane layer from top to bottom. The liquid flow channel is opened between two adjacent anion membrane layers and cation membrane layers, and the positions of the first water distribution holes and the second water distribution holes opened above the anion membrane layer and the cation membrane layer are staggered from each other, so that the electro-dialysis partition is not easily collapsed under pressure, not easily blocked in the flow channel, not easily leaked, and the service life of the electro-dialysis partition is enhanced.

[0004] However, in the actual use process of the above equipment, although it is not easily blocked in the flow channel and not easily leaked, in some special material purification fields, many materials often have high added value, and the owner may only provide a small volume of materials for experiments, often only 1L or even less can be provided. When performing percolation, it is impossible to efficiently purify a small amount of special materials, resulting in waste. In view of this, we have proposed a micro electro-dialysis partition with a loop. Content of the Utility Model

[0005] The purpose of the utility model is to provide a micro electro-dialysis partition with a loop to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A micro electro-dialysis partition with a loop, including an installation partition, an osmotic rhythm component is arranged on the outer wall of the installation partition. The osmotic rhythm component includes a polar water inlet, the polar water inlet is opened on the outer wall of the installation partition, a concentrated water inlet is opened on the outer wall of the installation partition, a fresh water inlet is opened on the outer wall of the installation partition, and a partition flow channel is opened on the outer wall of the installation partition.

[0007] A limiting hole is provided on the outer wall of the installation partition. A spiral arc-shaped baffle is fixedly connected to the inner wall of the partition flow channel, and a flow splitting fluctuation port is formed on the outer wall of the spiral arc-shaped baffle.

[0008] Preferably, the partition flow channel is arranged in a "U" shape. One end of the partition flow channel is connected to the concentrated water inlet, and the other end of the partition flow channel is connected to the fresh water inlet, so as to enable stable transmission of the liquid.

[0009] Preferably, a plurality of spiral arc-shaped baffles are provided, and the plurality of spiral arc-shaped baffles are arranged in a linear array on the inner wall of the partition flow channel, so as to stir and disturb the touched solution.

[0010] Preferably, a plurality of flow splitting fluctuation ports are provided, and the plurality of flow splitting fluctuation ports are arranged on the outer walls of the plurality of spiral arc-shaped baffles in a staggered form, so that the passed solution can be better stirred, and the flowing solution can be dialyzed more quickly.

[0011] Preferably, a flow disturbance component is provided on the outer wall of the spiral arc-shaped baffle. The flow disturbance component includes a flow splitting inclined plate fixedly connected to the outer wall of the spiral arc-shaped baffle, and a touch splitting arc-shaped plate fixedly connected to the outer wall of the flow splitting inclined plate.

[0012] Preferably, a plurality of touch splitting arc-shaped plates are provided, and the plurality of touch splitting arc-shaped plates are arranged on the outer wall of the flow splitting inclined plate in a staggered form, so as to further stir the disturbed solution, and thus the solution on the partition flow channel can be dialyzed better.

[0013] Compared with the prior art, the present utility model provides a micro looped electrodialysis partition, which has the following beneficial effects:

[0014] 1. When the solution is dialyzed daily by this micro looped electrodialysis partition, the solution will flow on the partition flow channel. By adopting a loop design, the water flow path is greatly extended. Compared with the partition without a loop of the same specification, the desalination rate is greatly improved, which is especially suitable for a microscale experimental environment. When the solution touches the spiral arc-shaped baffle and the flow splitting fluctuation port, the passed solution can be disturbed and guided from multiple angles, so that the solution can pass through the partition flow channel more quickly for efficient dialysis to prevent waste. By providing the limiting hole, it ensures the positioning function during equipment assembly, prevents the membrane and the partition from shifting, and at the same time retains as much sealing surface as possible to prevent external leakage during equipment operation, further enhancing the overall practicality.

[0015] 2. When the solution touches the spiral arc-shaped baffle and the shunt fluctuation port, the passing solution can be disturbed and guided at multiple angles. When the disturbing inclined plate and the touching arc-shaped plate further touch the disturbed solution, the solution in the baffle flow channel can be better dialyzed, enabling efficient purification of a small amount of special materials and preventing waste.

[0022] As Figures 1-5 shown, the present invention provides a technical solution: a micro looped electrodialysis baffle, including an installation baffle 1, an outer wall of the installation baffle 1 is provided with a permeation rhythm component 2, the permeation rhythm component 2 includes a polar water inlet 201, the polar water inlet 201 is opened on the outer wall of the installation baffle 1, a concentrated water outlet 202 is opened on the outer wall of the installation baffle 1, a fresh water outlet 203 is opened on the outer wall of the installation baffle 1, a baffle flow channel 204 is opened on the outer wall of the installation baffle 1, a limit hole 205 is opened on the outer wall of the installation baffle 1, an inner wall of the baffle flow channel 204 is fixedly connected with a spiral arc-shaped baffle 206, and a shunt fluctuation port 207 is opened on an outer wall of the spiral arc-shaped baffle 206.

[0023] In an embodiment of the present utility model, the partition flow channel 204 is arranged in a "U" shape. One end of the partition flow channel 204 is connected to the concentrated water inlet 202, and the other end of the partition flow channel 204 is connected to the fresh water outlet 203, so as to enable stable transmission of the water liquid. A plurality of spiral arc-shaped baffles 206 are arranged, and the plurality of spiral arc-shaped baffles 206 are arranged in a linear array on the inner wall of the partition flow channel 204, so as to stir and disturb the touched solution. A plurality of shunt fluctuation ports 207 are arranged, and the plurality of shunt fluctuation ports 207 are arranged in a staggered form on the outer walls of the plurality of spiral arc-shaped baffles 206, so that the passed solution can be better stirred, and the flowing solution can be dialyzed more quickly. A turbulence component 3 is arranged on the outer wall of the spiral arc-shaped baffle 206. The turbulence component 3 includes a turbulence dividing inclined plate 301. The turbulence dividing inclined plate 301 is fixedly connected to the outer wall of the spiral arc-shaped baffle 206. A touch dividing arc-shaped plate 302 is fixedly connected to the outer wall of the turbulence dividing inclined plate 301. A plurality of touch dividing arc-shaped plates 302 are arranged, and the plurality of touch dividing arc-shaped plates 302 are arranged in a staggered form on the outer wall of the turbulence dividing inclined plate 301, so as to further stir the disturbed solution, and thus the solution on the partition flow channel 204 can be better dialyzed.

[0024] The size of the partition 1 is 120mm×200mm, and the inner frame size is 170mm×94mm. On the basis of miniaturization, space is fully utilized as much as possible to maximize the use efficiency. Different from the non-loop electrodialysis partition, the present utility model removes the traditional mesh cloth and replaces it with a loop, ensuring smooth water flow and sufficient support strength. And a loop design is adopted, greatly extending the water flow path. Compared with the non-loop partition of the same specification, the desalination rate is greatly improved, which is especially suitable for the micro-experiment environment.

[0025] Since the amount of water in the micro-electrodialysis experimental machine is small, the flow rate is small, and the flow aperture is also small. A little deviation during assembly will have a great impact on the flow rate of the equipment. Therefore, a limiting hole 205 is provided. While facilitating the assembly of the equipment, it ensures that the flow holes can be aligned without deviation, effectively ensuring the flow rate of the equipment. At the same time, compared with a circular hole, the semi-circular hole occupies a smaller area. While playing a positioning role, it also retains a sufficiently large sealing area to ensure that the equipment does not leak water. Moreover, the partition flow channels 204 are all chamfered, which can effectively reduce the dead water area of the water flow and at the same time reduce the water flow resistance.

[0026] In the present utility model, during the daily dialysis of a solution, the solution flows on the partition flow channel 204. By adopting a loop design, the water flow path is greatly extended. Compared with partition plates of the same specification without a loop, the desalination rate is significantly increased, which is particularly suitable for microscale experimental environments. Moreover, when the solution touches the spiral arc-shaped baffle 206 and the shunt fluctuation port 207, the passing solution can be disturbed and guided at multiple angles, so that the solution can pass through the partition flow channel 204 more quickly for efficient dialysis to prevent waste. In addition, by setting the limiting holes 205, it ensures the positioning function during equipment assembly, prevents the membrane and the partition from shifting, and retains as much sealing surface as possible to prevent external leakage during equipment operation, further enhancing the overall practicality.

[0027] And when the solution touches the spiral arc-shaped baffle 206 and the shunt fluctuation port 207 and the passing solution is disturbed and guided at multiple angles, the disturbance inclined plate 301 and the touch-division arc-shaped plate 302 can further touch the disturbed solution, so that the solution on the partition flow channel 204 can perform better dialysis, enabling the efficient purification of a small amount of special materials and preventing waste.

[0028] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
