Description

Technical Field

[0001] The utility model relates to the field of water purification processing, in particular to a water guiding block of an EDI membrane stack. Background Technique

[0002] The EDI membrane stack is the core component of the electrodeionization system, which can remove minerals, ions and other impurities in water during the continuous process. The water guiding block is responsible for evenly distributing the water flow entering the EDI module to ensure that the water flow can flow smoothly and evenly through each part.

[0003] The existing Chinese patent with the application number CN201920596217.1 discloses a water guiding block of an EDI membrane stack, which includes a water guiding block body. One end of the water guiding block body is provided with a water outlet, and the other end is provided with a water inlet. The water outlet includes a plurality of first water resistance flanges arranged in a distributed manner. A plurality of first water guiding grooves arranged in a distributed manner are formed between two adjacent first water resistance flanges. The width of the first water resistance flange at the end far from the water inlet is smaller than the width of the first water resistance flange at the end close to the water inlet. Thus, the number of the first water guiding grooves at the end far from the water inlet is denser, and the number of the first water guiding grooves at the end close to the water inlet is sparser. In this way, the water to be filtered can enter the chamber containing the filtering material more evenly after passing through the water guiding block, improving the quality of water treatment.

[0004] In the above technology, through the design that the number of the first water guiding grooves at the end far from the water inlet is more than that at the end close to the water inlet, the water to be filtered can enter the chamber containing the filtering material more evenly after passing through the water guiding block. However, the high-speed flowing water has strong inertia. When the water flow rate is large, the water flow tends to continue flowing along the initial direction. As a result, the water pressure forces a large part of the water flow to quickly pass through the first water guiding grooves at the end close to the water inlet with smaller path resistance. Therefore, the first water guiding grooves at the end close to the water inlet are more likely to attract more water flow. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water guiding block of an EDI membrane stack. By using this device to work, the problem that the high-speed flowing water has strong inertia, the water flow tends to continue flowing along the initial direction, and the first water guiding grooves at the end close to the water inlet are more likely to attract more water flow is solved.

[0006] To achieve the above object, the utility model provides the following technical solution: A water guiding block of an EDI membrane stack, which includes a water guiding block body, a water inlet arranged on one side of the water guiding block body, a water outlet arranged on the other side of the water guiding block body, and a mounting seat arranged at the middle position inside the water guiding block body. The water guiding block body includes a first water guiding block and a second water guiding block. An annular water isolation belt and a first water resistance part are arranged inside the second water guiding block. A first water resistance flange is arranged at the top of the first water resistance part. Multiple groups of the annular water isolation belt and the first water resistance part are arranged. A first drainage groove is formed between every two groups of the annular water isolation belts, and a second drainage groove is formed between every two groups of the first water resistance flanges. The first drainage groove and the second drainage groove are arranged perpendicular to each other. The water inlet is arranged at the second water guiding block, and the first water guiding block and the second water guiding block are fixedly connected.

[0007] Further, a second water resistance part is arranged inside the first water guiding block. A second water resistance flange is arranged at the top of the second water resistance part. Multiple groups of the second water resistance parts are arranged. A first water guiding groove or a second water guiding groove is formed between every two groups of the second water resistance flanges. The first water guiding groove is arranged parallel to the first drainage groove, and the second water guiding groove is arranged parallel to the second drainage groove.

[0008] Further, the water outlet includes a third water resistance flange. Multiple groups of the third water resistance flanges are arranged. A water outlet groove is formed between every two groups of the third water resistance flanges.

[0009] Further, the number of water outlet grooves arranged on one side of the first water guiding block is more than that arranged on one side of the second water guiding block.

[0010] Further, mounting holes are formed on the upper surface of the mounting seat.

[0011] Further, the two corners inside the third water resistance flange are circular chamfers, and both ends of the second water resistance flange and the first water resistance flange are arc-shaped.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] For the water guiding block of the EDI membrane stack proposed by the utility model, when water flows in from the water inlet, it first undergoes preliminary adjustment treatment by the annular water isolation belt, so that part of the water flows along the first drainage groove to the first water guiding block. The water flowing through the annular water isolation belt is blocked by the first water resistance part for secondary adjustment treatment. Through the optimization of the annular water isolation belt and the first water resistance part, the amount of water flowing out along the second drainage groove will finally decrease. By setting the annular water isolation belt and the first water resistance part, it is convenient to more precisely control the flow direction and flow rate of water, optimize the water flow path, so as to improve the uniformity of water flow and reduce the phenomenon that water flow is overly concentrated in certain areas, and solve the problem that the water with high speed has strong inertia and the water flow is more inclined to continue flowing along the initial direction, and the first water guiding groove near the water inlet end is more likely to attract more water flow.

The water inlet 2 is provided at the second water guide block 12, and the first water guide block 11 and the second water guide block 12 are fixedly connected.

[0020] Next, the present utility model will be further described in conjunction with the embodiments.

[0021] Embodiment 1:

[0022] Please refer to Figure 1 - Figure 2, a second water resistance part 7 is arranged inside the first water guide block 11. A second water resistance flange 71 is arranged at the top of the second water resistance part 7. Multiple groups of the second water resistance parts 7 are arranged. A first water guide groove 711 or a second water guide groove 712 is formed between every two groups of the second water resistance flanges 71. The first water guide groove 711 is arranged in parallel with the first drainage groove 51, and the second water guide groove 712 is arranged in parallel with the second drainage groove 62. Through the staggered arrangement of the first water guide groove 711 and the second water guide groove 712, it is convenient to realize the multi-level and multi-direction guidance of water flow, which helps to form a more complex water flow path, ensure the uniform distribution and multi-level flow of water flow inside the first water guide block 11, and reduce the retention of water flow in a specific area.

[0023] The water outlet 4 includes a third water resistance flange 41. Multiple groups of the third water resistance flanges 41 are arranged. A water outlet groove 42 is formed between every two groups of the third water resistance flanges 41. The water inside the water guide block body 1 flows out through the water outlet groove 42. The arrangement of the third water resistance flange 41 is convenient for adjusting and uniformly distributing the water flow at the water outlet 4.

[0024] The number of the water outlet grooves 42 arranged on one side of the first water guide block 11 is more than that arranged on one side of the second water guide block 12. The number of the water outlet grooves 42 arranged on one side of the first water guide block 11 is denser, and the number of the water outlet grooves 42 arranged on one side of the second water guide block 12 is sparser, which is convenient for balancing the flow rate distribution.

[0025] Mounting holes 31 are formed on the upper surface of the mounting seat 3. Through the mounting holes 31, it is convenient to fix the water guide block body 1 to the system frame.

[0026] The two corners inside the third water resistance flange 41 are round chamfers, and both ends of the second water resistance flange 71 and the first water resistance flange 61 are arc-shaped. The round chamfer and arc-shaped design are convenient for the smooth transition of the water flow path, so as to reduce the water flow resistance and improve the water flow passing efficiency.

[0027] During use, the water guide block body 1 can be easily fixed to the system framework through the mounting holes 31. When water flows in from the water inlet 2, it first undergoes preliminary adjustment by the annular water isolation belt 5, causing part of the water to flow along the first drainage groove 51 to the first water guide block 11. With the staggered arrangement of the first water guide groove 711 and the second water guide groove 712 in the first water guide block 11, it is convenient to achieve multi-level and multi-directional guidance of the water flow, which helps to form a more complex water flow path, ensuring uniform distribution and multi-level flow of the water flow inside the first water guide block 11 to reduce the retention of water flow in specific areas. The water flow passing through the annular water isolation belt 5 is blocked by the first water resistance part 6 for secondary adjustment. After the optimization of the annular water isolation belt 5 and the first water resistance part 6, the amount of water flowing out along the second drainage groove 62 will decrease. Through the arrangement of the annular water isolation belt 5 and the first water resistance part 6, it is convenient to more precisely control the flow direction and flow rate of the water flow, optimize the water flow path, improve the uniformity of the water flow, and reduce the phenomenon of excessive concentration of water flow in some areas.
