Description

Technical Field

[0001] The utility model relates to the technical field related to EDI membrane stacks, in particular to an adjustable partition plate of a multi-stage EDI membrane stack. Background Art

[0002] EDI membrane stack, or EDI device, is an EDI unit formed by sandwiching ion exchange resin between anion / cation exchange membranes. In the EDI assembly, a certain number of EDI units are separated by mesh to form a concentrated water chamber, and anion / cation electrodes are set at both ends of the unit group. Under the drive of direct current, anions and cations in the water flow in the fresh water chamber pass through the anion and cation exchange membranes respectively into the concentrated water chamber and are removed in the fresh water chamber. The EDI membrane stack is composed of a plurality of baffles and conversion membranes stacked on each other, and the conversion membranes currently used are usually simple in structure. After the conversion membrane and the baffle are combined with each other, it is necessary to cooperate with the sealing strip to seal the connection between the conversion membrane and the water storage tank. The installation process is cumbersome, and with the increase of use time, the sealing strip is prone to deformation, resulting in reduced sealing effect. At the same time, it is not convenient to adjust according to needs, so there is inconvenience in use.

[0003] Chinese patent document CN216512986U discloses an EDI membrane stack adjustable baffle, including a baffle and a conversion membrane, wherein the baffle is provided with fixing holes, and a plurality of fixing holes are arranged at equal intervals, and the fixing holes penetrate both sides of the baffle; a water storage tank is provided in the middle of the baffle, and the water storage tank penetrates both sides of the baffle, and the center line of the water storage tank and the center line of the baffle are on the same vertical line. The above-mentioned EDI membrane stack adjustable baffle has shortcomings. Although the device achieves an increase in sealing, it has limitations. The two baffles are inconvenient to install and are prone to sliding, resulting in the sealing strips not being able to fit each other, thereby causing a decrease in sealing, or even directly causing an inability to seal. Secondly, the conversion membrane is sealed with a single sealing strip, and the sealing effect is poor.

[0004] Therefore, in order to solve such problems, we propose a multi-stage EDI membrane stack with adjustable baffles. Utility Model Content

[0023] Reference Figure 1-5 The utility model provides an embodiment: a multi-stage EDI membrane stack adjustable partition, including a partition body 1, two non-adjacent side walls of the partition body 1 are each provided with a first installation groove 101, a card slot 102 is provided on the side wall of the partition body 1, a water storage tank 103 is provided on the side wall of the partition body 1, and the card slot 102 is located between the water storage tanks 103, a connecting seat 11 is fixedly connected to the side wall of the partition body 1, and the connecting seat 11 and the card slot 102 are located on the same side wall, and a connecting frame 111 is fixedly connected to the side wall of the partition body 1 away from the connecting seat 11, and two first sealing strips 12 are provided on the side wall of the partition body 1, and the first sealing strips 12 are respectively located in the first installation groove 101, and a second sealing strip 13 is provided inside the partition body 1, and the second sealing strip 13 is located on the side wall of the water storage tank 103, and a card block 14 is fixedly connected to the side wall of the partition body 1, and the card block 14 is located on the side wall of the partition body 1 away from the card slot 102, and a conversion membrane 3 is provided on the side wall of the partition body 1.

[0024] When the two partition bodies 1 are installed, the connection seat 11 of the side wall of one partition body 1 is directly engaged with the connection frame 111 of the other partition body 1, and then fixed through the fixing holes to prevent the two partition bodies 1 from sliding during installation, which in turn causes the first sealing strips 12 on the side walls of the two partition bodies 1 to be unable to fit each other, or even to achieve a sealing effect. Secondly, when the two partition bodies 1 are spliced, the block 14 on the side wall of one partition body 1 drives the conversion membrane 3 to be inserted into the groove 102 on the side wall of the other partition body 1, and then the second sealing strip 13 is used for further sealing to ensure the tightness of the connection between the conversion membrane 3 and the water storage tank 103.

[0025] Two first water pipes 2 are fixedly connected to the side wall of the partition body 1, and first sealing rubber rings 15 are sleeved on both ends of the first water pipes 2. Two second water pipes 21 are fixedly connected to the side wall of the partition body 1, and second sealing rubber rings 16 are sleeved on both ends of the second water pipes 21. The first water pipe 2 and the second water pipe 21 both pass through the partition body 1, and are used to utilize the sealing connection between the first sealing rubber ring 15 and the second sealing rubber ring 16 to increase the tightness of the connection between the first water pipe 2 and the second water pipe 21.

[0026] Both ends of the conversion membrane 3 are fixedly connected with connecting plates 31, and the end of the connecting plate 31 away from the conversion membrane 3 is fixedly connected with a connecting ring 32. The connecting rings 32 are respectively sleeved with the outer wall of the first sealing rubber ring 15 for installing the conversion membrane 3 and limiting the conversion membrane 3 at the same time to prevent the conversion membrane 3 from being offset when the block 14 drives the conversion membrane 3 to be inserted into the slot 102, thereby increasing the tightness of the connection between the conversion membrane 3 and the water storage tank 103.

[0027] The connecting seat 11 of one partition body 1 side wall is snap-connected with the connecting frame 111 of another partition body 1 side wall for quick connection of the two partition bodies 1 to prevent the first sealing strips 12 of the two partition body 1 side walls from failing to fit each other.

[0028] The area of ​​the conversion film 3 is larger than the cross-sectional area between the clamping blocks 14 , so that after the conversion film 3 is driven by the clamping blocks 14 to clamp into the clamping slot 102 , the conversion film 3 seals the water storage tank 103 .

[0029] The sum of the lengths of the first water pipe 2 and the second water pipe 21 outside the partition body 1 is smaller than the sum of the lengths of the connecting seat 11 and the connecting frame 111, so as to avoid the connection between the connecting seat 11 and the connecting frame 111 being unable to be snap-connected due to the first water pipe 2 and the second water pipe 21 being too long.

[0030] Working principle: First, when the two partition bodies 1 are installed, the connecting seat 11 of the side wall of one partition body 1 is directly engaged with the connecting frame 111 of the other partition body 1, and then fixed through the fixing holes to prevent the two partition bodies 1 from sliding during installation, which will cause the first sealing strips 12 on the side walls of the two partition bodies 1 to be unable to fit each other, or even unable to achieve a sealing effect. Secondly, when the two partition bodies 1 are spliced, the block 14 on the side wall of one partition body 1 drives the conversion membrane 3 to be inserted into the groove 102 on the side wall of the other partition body 1, thereby realizing the first fitting of the conversion membrane 3 and the water tank 103, and then the second sealing strip 13 is used for further sealing to realize the second fitting of the conversion membrane 3 and the water tank 103, thereby ensuring the tightness of the connection between the conversion membrane 3 and the water tank 103.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
