Description

Technical Field

[0001] This utility model relates to the technical field of electrodialysis devices, specifically to an electrodialysis device for improving the decolorization effect of dicarboxylic acids. Background Technology

[0002] Improving the decolorization effect of diacids primarily relies on the optimization and application of electrodialysis technology. Electrodialysis, as a membrane separation technology, uses a direct current electric field to drive an ion exchange membrane to selectively permeate ions, thereby achieving the separation and purification of substances. Electrodialysis devices that improve the decolorization effect of diacids can utilize bipolar membrane electrodialysis technology. Under the action of the bipolar membrane, water molecules can be dissociated into hydrogen ions and hydroxide ions, which then react with salts in the solution to form corresponding acids and bases. This conversion ability helps remove colored substances from the solution, thus improving the decolorization effect of diacids.

[0003] During the use of an electrodialysis device, the membrane material may gradually age over time, leading to performance degradation, or even damage or cracks, resulting in leakage. The operating environment of the membrane stack has a significant impact on its performance. For example, excessively high or low temperatures, abnormal pH values, and the presence of toxic substances can all damage the membrane stack and cause leakage. If problems such as loose screws, leaking connecting pipes, or deformed supports are not properly addressed during the installation of the membrane stack, leakage may also occur during subsequent use. When leakage occurs, it is difficult to collect, increasing the difficulty of centralized recovery, which presents certain shortcomings. Therefore, we propose an electrodialysis device to improve the decolorization effect of dicarboxylic acids. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an electrodialysis device that improves the decolorization effect of dicarboxylic acids. By setting a transparent baffle and a collection component, the device can conveniently collect leaked liquid without affecting its use, and can monitor whether there is a leak. At the same time, the sealing component can seal the clamping component, preventing dust and liquid from contacting the clamping component and accelerating the corrosion rate.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a transparent baffle and a collection component, the leakage liquid can be conveniently collected without affecting the use of the electrodialysis device, and leakage can be monitored. At the same time, the sealing component can seal the clamping component, preventing dust and liquid from contacting the clamping component and accelerating the corrosion rate. In use, the transparent baffle prevents the leaked liquid from flowing into the collection tank of the collection component. After collection, the valve can be rotated to open the discharge pipe, and the leaked liquid can be recovered through the discharge pipe for use. When there is leaked liquid in the collection tank, the liquid level sensor can detect the liquid level and convert it into an output signal that can be transmitted to the control terminal, so as to monitor whether the electrodialysis device is leaking in real time for use. Then, the iron cover of the sealing component can be rotated to cover the fixing pipe. After being covered, the end of the clamping component can be sealed by the cooperation between the fixing pipe and the iron cover, while the middle of the clamping component can be sealed by the transparent baffle, effectively preventing dust and liquid from contacting the clamping component, thereby improving the service life of the clamping component.

[0040] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure will be partially enlarged, not at half scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0042] This invention provides an electrodialysis device for improving the decolorization effect of dicarboxylic acids. By setting a transparent baffle and a collection component, it achieves the effect of conveniently collecting leaked liquid without affecting the use of the electrodialysis device, and can monitor whether there is a leak. At the same time, the sealing component can seal the clamping component to prevent dust and liquid from contacting the clamping component and accelerating the corrosion rate.

[0043] Figure 1-6 The diagram shown is an overall structural schematic of one embodiment of an electrodialysis device for improving the decolorization effect of dicarboxylic acids according to this utility model. Please refer to [link / reference]. Figure 1-6 The main body of an electrodialysis device for improving the decolorization effect of dicarboxylic acids according to this embodiment includes: a membrane stack 100, an electrode plate 200, a fixing plate 300, a clamping assembly 400, a sealing assembly 500, a transparent baffle 600, and a collection assembly 700.

[0044] Specifically, when in use, the membrane stack 100 is usually composed of multiple bipolar membranes, cation exchange membranes and anion exchange membranes arranged alternately to form multiple compartments, including acid compartments, alkali compartments and feed compartments. These membranes are fixed together in a specific way (such as bolt clamping, frame support, etc.) to ensure the sealing between each compartment and the orderly migration of ions.

[0045] Specifically, electrode plates 200 are arranged on both sides of membrane stack 100. There are two electrode plates 200, which are the positive electrode plate and the negative electrode plate, respectively. In use, in the bipolar membrane electrodialysis device, when the power is turned on, the electrode plates 200 are immediately energized. At this time, ions in the solution begin to migrate in a direction under the action of the electric field. Cations move towards the cathode plate and anions move towards the anode plate. During the migration process, ions pass through the ion exchange membrane and bipolar membrane in membrane stack 100 and undergo ion exchange and chemical reactions on the membrane surface.

[0046] Specifically, the fixing plate 300 is arranged on the outside of the electrode plate 200, and the outside of the fixing plate 300 is provided with a bracket 301. The bottom of both brackets 301 is provided with a gasket, and the corner of the gasket is provided with a round hole. In use, the two fixing plates 300 can fix the electrode plate 200 and the membrane stack 100, the two brackets 301 are used to support the fixing plate 300, and the gasket can increase the contact area between the bracket 301 and the ground, which can improve stability.

[0047] Specifically, the clamping assembly 400 is arranged on two fixed plates 300. The clamping assembly 400 includes a connecting rod 401 inserted through the two fixed plates 300 and a nut 402 threadedly connected to the connecting rod 401. The connecting rod 401 is a double-threaded rod. Several clamping assemblies 400 are provided. In use, the connecting rod 401 can be passed through the two fixed plates 300. After passing through, the nut 402 is rotated to fix it. The two fixed plates 300 can be fixed by the clamping assembly 400 so as to fix the membrane stack 100 and the electrode plate 200.

[0048] Specifically, the sealing assembly 500 includes a fixing tube 501 disposed on the outside of the fixing plate 300 and an iron cover 502 hinged to the fixing tube 501. A magnet 503 is disposed on the right side of the fixing tube 501. The magnet 503 attracts the iron cover 502. In use, the iron cover 502 can rotate to cover the fixing tube 501. After being covered, the end of the clamping assembly 400 can be sealed by the cooperation between the fixing tube 501 and the iron cover 502. The middle part of the clamping assembly 400 can be sealed by the transparent baffle 600, effectively preventing dust and liquid from contacting the clamping assembly 400, so as to improve the service life of the clamping assembly 400.

[0049] Specifically, the transparent baffle 600 is inserted into the fixed plate 300. During use, the transparent baffle 600 blocks the leaked liquid so that it can only flow into the collection box 701 of the collection assembly 700 for use. The transparent baffle 600 does not obstruct the user's view so that the location of the leak can be seen.

[0050] Specifically, the collection assembly 700 includes a collection box 701 located at the bottom of the transparent baffle 600, a discharge pipe 702 located at the front end of the collection box 701, a valve 703 located on the discharge pipe 702, and a liquid level sensor 704 located inside the collection box 701. In use, the liquid blocked by the transparent baffle 600 can only flow into the collection box 701 of the collection assembly 700 due to gravity. After collection, the valve 703 can be rotated directly to open the discharge pipe 702. After opening, the leaked liquid can be recovered through the discharge pipe 702 for use. When there is leaked liquid in the collection box 701, the liquid level sensor 704 can sense the liquid level and convert it into an output signal that can be transmitted to the control terminal, so as to monitor whether the electrodialysis device is leaking in real time for use.

[0051] Furthermore, the collection component 700 is fixedly connected to the transparent baffle 600 by fasteners 800, which consist of bolts and nuts 402. In use, the transparent baffle 600 and the collection component 700 can be fixed by the fasteners 800 to facilitate the installation and removal of the transparent baffle 600 and the collection component 700. After being fixed, the blocking effect of the transparent baffle 600 ensures that the leaked liquid can only flow into the collection tank 701 of the collection component 700 for collection.

[0052] Combination Figures 1-6 This embodiment of an electrodialysis device for improving the decolorization effect of dicarboxylic acids, in specific use, is used so that the leaked liquid can only flow into the collection tank 701 of the collection component 700 by the blocking of the transparent baffle 600. After collection, the valve 703 can be rotated to open the discharge pipe 702. After opening, the leaked liquid can be recovered through the discharge pipe 702 for use. When there is leaked liquid in the collection tank 701, the liquid level sensor 704 can sense the liquid level and convert it into an output signal that can be transmitted to the control terminal, so as to monitor whether the electrodialysis device is leaking in real time for use. Then, the iron cover 502 of the sealing component 500 can be rotated to cover the fixing pipe 501. After being covered, the end of the clamping component 400 can be sealed by the cooperation of the fixing pipe 501 and the iron cover 502, while the middle part of the clamping component 400 can be sealed by the transparent baffle 600, effectively preventing dust and liquid from contacting the clamping component 400, so as to improve the service life of the clamping component 400.

[0053] Because the collection assembly 700 is relatively heavy when collecting leaked liquid, a support assembly 900 is proposed to improve its stability. The support assembly 900 includes a support rod 901 that is slidably connected to the bracket 301 and a fastening knob 902 that is threadedly connected to the support rod 901. The fastening knob 902 is a T-shaped stud. In use, the fastening knob 902 can be loosened, and after loosening, the support rod 901 can be moved up and down until it contacts the collection box 701 of the collection assembly 700. After contact, the fastening knob 902 is tightened, and the collection box 701 can be supported by the support rod 901 to improve the stability of the collection assembly 700.

[0054] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
