Description

Technical Field

[0001] The utility model relates to the technical field of pure water preparation, in particular to an electrolysis device for preparing ultrapure water. Background Art

[0002] Ultrapure water refers to water with almost no impurities, and no organic matter such as bacteria and viruses, and trace mineral elements. It is not suitable for drinking and is mainly used in industrial production. During the preparation of ultrapure water, the anode exchange membrane and the cathode exchange membrane are used under the action of an external DC electric field to bring together impurities such as salt in the water, forming concentrated water with high impurity content and fresh water without impurities. Fresh water without impurities can be used to prepare ultrapure water.

[0003] After a period of use, the anode exchange membrane and cathode exchange membrane of the existing electrolysis device for ultrapure water preparation need to be disassembled and replaced or disassembled and cleaned due to aging, membrane contamination, damage, etc. The existing connection method is to connect the outer frame of the exchange membrane to the device with bolts. Although the structure is simple, a large number of exchange membranes are usually arranged in the electrolysis device, resulting in more operations and cumbersome operations during replacement and cleaning. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide an electrolysis device for preparing ultrapure water to solve the technical problems mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electrolysis device for preparing ultrapure water, comprising a device body, an anode membrane assembly and a cathode membrane assembly, wherein both sides of the top of the device body are connected to a holder, and one side of the holder passes through a limit block, the limit block is respectively connected to a first spring and a pull rope, and one end of the pull rope is connected to a pull rod, a rubber pad is connected to the inside of the holder, an inner wall of the device body is connected to a top block, and a second spring is connected to the inside of the top block, a first contact piece is installed on the top of the top block, and second contact pieces are installed on both sides of the bottom of the anode membrane assembly and the cathode membrane assembly.

[0006] By adopting the above technical solution, when disassembling, it is only necessary to pull the pull rod to make multiple pull ropes move synchronously and pull the limit block. After the limit block is pulled, it retracts into the holder, thereby ending the limitation of the anode membrane assembly and the cathode membrane assembly, and then the anode membrane assembly and the cathode membrane assembly can be removed; when installing, it is only necessary to place the anode membrane assembly and the cathode membrane assembly in the holder and on the top of the limit block, and then it is only necessary to press down the anode membrane assembly and the cathode membrane assembly with force so that the limit block is retracted into the holder and compresses the first spring. When the anode membrane assembly and the cathode membrane assembly are pressed down to the bottom of the limit block, the first spring drives the limit block to extend from the holder, supporting the top of the anode membrane assembly and the cathode membrane assembly, thereby preventing the anode membrane assembly and the cathode membrane assembly from falling off.

[0007] Furthermore, one side of the top of the limit block is sloped, and both the anode membrane assembly and the cathode membrane assembly are in contact with the limit block.

[0008] By adopting the above technical solution, it is only necessary to press down the anode membrane assembly and the cathode membrane assembly with force so that the limit block is retracted into the holder and the first spring is compressed. When the anode membrane assembly and the cathode membrane assembly are pressed down to the bottom of the limit block, the first spring drives the limit block to extend out of the holder and support the top of the anode membrane assembly and the cathode membrane assembly, thereby preventing the anode membrane assembly and the cathode membrane assembly from falling off.

[0009] Furthermore, the limit block and the pull rope are both slidably connected to the card seat, and the pull rope is a nylon rope.

[0010] By adopting the above technical solution, it is only necessary to pull the pull rod to make multiple pull ropes synchronously displace and pull the limit blocks. After the limit blocks are pulled, they retract into the holder, thereby completing the limitation of the anode membrane assembly and the cathode membrane assembly.

[0011] Furthermore, the first contact piece and the second contact piece are both made of copper material, and the second contact piece abuts against the first contact piece.

[0012] By adopting the above technical solution, when the anode membrane assembly and the cathode membrane assembly are placed, the circuit is connected through the first contact piece and the second contact piece, without the need for additional wiring, effectively simplifying the disassembly and assembly process.

[0013] Furthermore, the cross section of the top block is in the shape of a Chinese character "几", and the top block is slidably connected to the device body.

[0014] By adopting the above technical solution, when the anode membrane assembly and the cathode membrane assembly are completed, the second spring drives the top block to move upward, thereby pushing the anode membrane assembly and the cathode membrane assembly upward to facilitate the removal of the anode membrane assembly and the cathode membrane assembly. At the same time, the rubber pad slows down the rising speed of the anode membrane assembly and the cathode membrane assembly to prevent the anode membrane assembly and the cathode membrane assembly from being directly bounced away.

[0015] Furthermore, the holder, the pull rope, the limit block, the first spring, the rubber pad, the top block, the second spring, the first contact piece and the second contact piece are all provided in plurality.

[0016] By adopting the above technical solution, it is convenient to quickly dismantle and install multiple anode membrane assemblies and cathode membrane assemblies without the need for wiring.

[0017] Furthermore, two pull rods are provided, and a plurality of pull ropes are respectively connected to the two pull rods.

[0018] By adopting the above technical solution, the pull rods are arranged to facilitate pulling multiple pull ropes at the same time, and the limiting of multiple anode membrane assemblies and cathode membrane assemblies can be completed at the same time by simply pulling two pull rods at the same time.

[0019] Furthermore, the bottom of the device body is connected to a concentrated water pipe and a fresh water pipe respectively, one side of the device body is connected to a water inlet pipe, and the anode membrane assembly and the cathode membrane assembly are both located inside the device body.

[0020] By adopting the above technical solution, the water to be treated flows into the main body of the device through the water inlet pipe. After the anode membrane assembly and the cathode membrane assembly are started, the impurities in the water to be treated are caused to pass through the anode membrane assembly and the cathode membrane assembly through the DC electric field. At this time, the impurities are collected in the water above the concentrated water pipe to form concentrated water rich in impurities, while the water above the fresh water pipe forms fresh water with few or no impurities. After that, the concentrated water can be discharged through the concentrated water pipe, and the fresh water can be discharged through the fresh water pipe.

[0021] Furthermore, the cross-sections of the anode membrane assembly and the cathode membrane assembly are both T-shaped.

[0022] By adopting the above technical solution, the cross-sections of the anode membrane assembly and the cathode membrane assembly are both T-shaped, with the upper sides of both sides protruding outwards, so as to facilitate entry into the interior of the holder for positioning.

[0023] Furthermore, a guide block is fixed on the top of the holder, and the top of the guide block is sloped.

[0024] By adopting the above technical solution, the staff places the anode membrane assembly in the holder and above the top block. At the same time, the setting of the guide block facilitates the anode membrane assembly to enter the holder.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The utility model is provided with a holder, a pull rod, a pull rope, a limit block and a first spring. When disassembling, it is only necessary to pull the pull rod to make multiple pull ropes displace synchronously and pull the limit block. After the limit block is pulled, it retracts into the holder, thereby ending the limitation of the anode membrane assembly and the cathode membrane assembly. Thereafter, the anode membrane assembly and the cathode membrane assembly can be removed. When installing, it is only necessary to place the anode membrane assembly and the cathode membrane assembly in the holder and at the top of the limit block. Then, it is only necessary to press down the anode membrane assembly and the cathode membrane assembly with force so that the limit block is retracted into the holder and the first spring is compressed. When the anode membrane assembly and the cathode membrane assembly are pressed down to the bottom of the limit block, the first spring drives the limit block to extend from the holder, supporting the top of the anode membrane assembly and the cathode membrane assembly, thereby preventing the anode membrane assembly and the cathode membrane assembly from falling off. It is convenient and quick to disassemble and assemble, and the operation is simple and convenient.

[0027] 2. Through the arrangement of the rubber pad, the top block and the second spring, when the operation on the anode membrane assembly and the cathode membrane assembly is completed, the second spring drives the top block to move upward, thereby pushing the anode membrane assembly and the cathode membrane assembly upward, facilitating the removal of the anode membrane assembly and the cathode membrane assembly. Meanwhile, the rubber pad slows down the rising speed of the anode membrane assembly and the cathode membrane assembly, preventing the anode membrane assembly and the cathode membrane assembly from being directly ejected; it is convenient to remove the anode membrane assembly and the cathode membrane assembly.

[0028] 3. Through the arrangement of the first contact piece and the second contact piece, when the anode membrane assembly and the cathode membrane assembly are properly placed, the circuit is connected through the first contact piece and the second contact piece, eliminating the need for additional wiring, effectively simplifying the disassembly and assembly operation process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0036] The following will describe the embodiments of the present utility model based on its overall structure.

[0037] Embodiment 1:

[0038] An electrolysis device for preparing ultrapure water, as Figures 1 - 5 shown, includes a device main body 1, an anode membrane assembly 5 and a cathode membrane assembly 6. Both sides of the top of the device main body 1 are connected with card seats 7. One side of the card seat 7 is penetrated by a limit block 11. One side of the top of the limit block 11 is in a slope shape. Both the anode membrane assembly 5 and the cathode membrane assembly 6 are abutted against the limit block 11. The cross-sections of both the anode membrane assembly 5 and the cathode membrane assembly 6 are in a "T" shape. The inside of the limit block 11 is respectively connected with a first spring 12 and a pull rope 10. Both the limit block 11 and the pull rope 10 are slidably connected with the card seat 7. The pull rope 10 is a nylon rope. One end of the pull rope 10 is connected with a pull rod 9. The staff pulls the pull rod 9 to synchronously displace multiple pull ropes 10 to pull the limit block 11. After the limit block 11 is pulled, it retracts into the card seat 7 and compresses the first spring 12, thereby ending the limitation of the anode membrane assembly 5;

[0039] A rubber pad 13 is connected inside the card seat 7. A top block 14 is connected to the inner wall of the device main body 1. The cross-section of the top block 14 is in a "Ji" shape. The top block 14 is slidably connected with the device main body 1. A second spring 15 is connected inside the top block 14. The second spring 15 drives the top block 14 to move upward, thereby pushing the anode membrane assembly 5 upward, so as to facilitate the staff to remove the anode membrane assembly 5. At the same time, the rising speed of the anode membrane assembly 5 is slowed down by the rubber pad 13, avoiding the anode membrane assembly 5 being directly bounced off due to inertia;

[0040] A first contact piece 16 is installed on the top of the top block 14. Both sides of the bottom of the anode membrane assembly 5 and the cathode membrane assembly 6 are installed with second contact pieces 17. Both the first contact piece 16 and the second contact piece 17 are made of copper material. The second contact piece 17 is abutted against the first contact piece 16. When the anode membrane assembly 5 and the cathode membrane assembly 6 are placed well, the circuit is connected through the first contact piece 16 and the second contact piece 17, and no additional wiring is required.

[0041] Refer to Figures 1 - 5 , in the above embodiment, a concentrated water pipe 2 and a fresh water pipe 3 are respectively connected to the bottom of the device main body 1. A water inlet pipe 4 is connected to one side of the device main body 1. Both the anode membrane assembly 5 and the cathode membrane assembly 6 are located inside the device main body 1. The water to be treated flows into the device main body 1 through the water inlet pipe 4. After the anode membrane assembly 5 and the cathode membrane assembly 6 are started, the impurities in the water to be treated pass through the anode membrane assembly 5 and the cathode membrane assembly 6 through a direct current electric field. At this time, the impurities are concentrated in the water above the concentrated water pipe 2 to form concentrated water rich in impurities, while the water above the fresh water pipe 3 forms fresh water with less or no impurities. Then, the concentrated water can be discharged through the concentrated water pipe 2, and the fresh water is discharged through the fresh water pipe 3.

[0042] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 5, in the above embodiments, there are multiple card seats 7, pulling ropes 10, limiting blocks 11, first springs 12, rubber pads 13, top blocks 14, second springs 15, first contact pieces 16 and second contact pieces 17, and there are two pull rods 9. The multiple pulling ropes 10 are respectively connected to the two pull rods 9, which facilitates the disassembly and assembly of the multiple anode membrane assemblies 5 and cathode membrane assemblies 6.

[0043] Embodiment 2:

[0044] Based on the above Embodiment 1, although the disassembly and assembly are facilitated by setting structures such as the card seat 7, the pull rod 9, the pulling rope 10, the limiting block 11, and the first spring 12, when installing each time, the anode membrane assembly 5 and the cathode membrane assembly 6 need to be aligned and placed, otherwise it is difficult to install. Now, by setting the guiding block 8, it is convenient to guide the anode membrane assembly 5 and the cathode membrane assembly 6.

[0045] Refer to Figures 1 - 5 , in the above embodiments, a guiding block 8 is fixed to the top of the card seat 7, and the top of the guiding block 8 is in a slope shape. The setting of the guiding block 8 facilitates the anode membrane assembly 5 to enter the card seat 7.

[0046] The implementation principle of the present utility model is as follows: First, the water to be treated flows into the interior of the device main body 1 through the water inlet pipe 4. After the anode membrane assembly 5 and the cathode membrane assembly 6 are started, the impurities in the water to be treated pass through the anode membrane assembly 5 and the cathode membrane assembly 6 under the direct current electric field. At this time, the impurities gather in the water above the concentrated water pipe 2 to form concentrated water rich in impurities, while the water above the fresh water pipe 3 forms fresh water with less or no impurities. Then, the concentrated water can be discharged through the concentrated water pipe 2, and the fresh water is discharged through the fresh water pipe 3;

[0047] When the anode membrane assembly 5 and the cathode membrane assembly 6 are aged, damaged and need to be replaced, or when the anode membrane assembly 5 and the cathode membrane assembly 6 are blocked and need to be disassembled and cleaned, the staff pulls the pull rod 9 to synchronously displace the multiple pulling ropes 10 to pull the limiting block 11. After being pulled, the limiting block 11 retracts into the card seat 7 and compresses the first spring 12, thereby ending the limitation of the anode membrane assembly 5. At this time, the second spring 15 drives the top block 14 to move upward, thereby pushing the anode membrane assembly 5 upward, so as to facilitate the staff to remove the anode membrane assembly 5. At the same time, the rising speed of the anode membrane assembly 5 is slowed down by the rubber pad 13 to prevent the anode membrane assembly 5 from being directly bounced off due to inertia. The disassembly operation of the cathode membrane assembly 6 is the same;

[0048] During installation, the staff places the anode membrane assembly 5 in the holder 7 and above the top block 14. At the same time, the setting of the guide block 8 facilitates the anode membrane assembly 5 to enter the holder 7. Then the staff presses down the anode membrane assembly 5 with force, so that the anode membrane assembly 5 and the top block 14 move downward. After the top block 14 moves downward, it retracts into the interior of the device body 1 and compresses the second spring 15. When the anode membrane assembly 5 is pressed down to the bottom of the limit block 11, the limit block 11 is no longer blocked. At this time, the first spring 12 drives the limit block 11 to extend from the holder 7, supporting the top of the anode membrane assembly 5, thereby preventing the anode membrane assembly 5 from falling off. The installation operation of the cathode membrane assembly 6 is the same;

[0049] When the anode membrane assembly 5 and the cathode membrane assembly 6 are placed, the circuit is connected through the first contact piece 16 and the second contact piece 17, without the need for additional wiring, which effectively simplifies the disassembly and assembly process. At the same time, the top block 14 and the second spring 15 cooperate to always apply an upward force to the first contact piece 16, so that the first contact piece 16 and the second contact piece 17 are tightly connected, avoiding the occurrence of false connection and heat generation.

The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
