Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to an acid-base separation type fully automatic electrochemical water treatment device. Background Technology

[0002] In recent years, with the continuous acceleration of my country's industrialization, the amount of wastewater discharged has also increased year by year, especially wastewater containing chloride, calcium, and magnesium ions. Water is an important resource for human survival and development. If wastewater cannot be effectively treated, it will seriously affect human survival and development.

[0003] Existing publication number CN110304697B discloses a dual-cathode, three-stage electrochemical wastewater treatment device, including a shell divided into an electrolysis chamber and a purified water chamber by a partition; and an electrode assembly arranged in the electrolysis chamber. The electrode assembly includes an outer cathode cylinder, a middle anode cylinder, and an inner composite cathode cylinder. The outer cathode cylinder and the inner composite cathode cylinder are arranged in parallel. In the process of realizing this utility model, the inventors discovered the following problems with the prior art:

[0004] Although existing wastewater treatment equipment uses a combination of cathode and anode membranes for purification, the membrane structure has limited adsorption capacity for dirt. Therefore, once the membrane adsorption reaches its limit, the membrane structure can no longer continue to work. Moreover, since both the structure and the liquid used for purification are hazardous, the replacement process requires manual entry into the equipment to remove the membrane. This replacement method is difficult to remove and also difficult to replace.

[0005] Therefore, an acid-base separation type fully automatic electrochemical water treatment device is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an acid-base separation type fully automatic electrochemical water treatment device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an acid-base separation type fully automatic electrochemical water treatment device, including a tank and a membrane assembly. A support bracket is bolted to the bottom of the tank, and lifting brackets are bolted to both sides of the tank. The membrane assembly is located directly below the lifting brackets on the tank. The membrane assembly includes a box, a replacement membrane, and a blocking bracket. Two sets of blocking brackets are arranged alternately on the outer surface of the box, and a replacement membrane is connected between the two sets of blocking brackets. An anode plate is arranged at the bottom of the box.

[0009] Preferably, the replacement membrane is connected to a membrane cover on its side, and both sides of the membrane cover are provided with grooves for connecting with the snap ring. A sealing ring is fitted at the edge of the membrane cover. When the replacement membrane is inserted into the box, the blocking bracket resets and squeezes the membrane cover to fit against the box.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this fully automatic electrochemical water treatment device with acid-base separation uses a blocking support structure. When the semi-permeable membrane needs to be replaced, simply pull the locking head to release the limit on the connecting rod, and pull the limit block to separate the replacement membrane from the housing. After replacing the membrane, manually squeeze the membrane cover to insert the snap ring into the membrane cover slot, and release the locking head to complete the limit fixation. This plug-and-play replacement reduces the use of disassembly tools and steps, significantly shortening maintenance time. Even if the sealing ring of the newly replaced membrane cannot fit perfectly at first, a seal can be achieved through a simple squeezing operation, reducing the professional skills required for maintenance personnel and minimizing equipment downtime.

[0017] Compared with existing technologies, this fully automatic electrochemical water treatment device with acid-base separation uses a lifting bracket to drive the anode plate to move up and down via a hydraulic rod, which can control the contact state between the anode plate and the cathode plate. In conjunction with the semi-permeable membrane in the membrane box, it can purify and adsorb substances in the water source. The ball valves on the delivery pipes make them independent, and the delivery situation can be flexibly adjusted according to the actual treatment needs to control the input of acidic liquid.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0029] As attached Figures 1 to 9 The diagram shows a housing 1 and a membrane assembly 12. A support bracket 2 is bolted to the bottom of the housing 1 to support the overall structure of the housing 1. A lifting bracket 3 moves the cathode plate, bringing the anode and cathode plates into contact. This, in conjunction with the semi-permeable membrane inside the membrane box, purifies and adsorbs substances in the water source. The replaceable membrane 18 is specifically a semi-permeable membrane structure. Lifting brackets 3 are bolted to both sides of the housing 1. The membrane assembly 12 is located directly below the lifting brackets 3 on the housing 1. The membrane assembly 12 includes a housing 1201, a replaceable membrane 18, and blocking brackets 19. Two sets of blocking brackets 19 are arranged in an alternating pattern on the outer surface of the housing 1201, connecting the two sets of blocking brackets 19 to the replaceable membrane 18. Anode plates are arranged at the bottom of the housing 1201. The replaceable membrane 18 can be separated from the housing 1201 after purification for replacement.

[0030] In a preferred embodiment, the blocking bracket 19 includes a mounting block 20, and a connecting rod 22 is slidably connected to the side of the mounting block 20. A through hole is provided at the center of the mounting block 20 for the connecting rod 22 to move. When it is necessary to separate the connecting rod 22 from the replacement film 18 provided on the housing 1201, the locking head 24 is pulled to release the restriction on the connecting rod 22. Then, the limiting block 23 is pulled, causing the locking head 24 to re-insert into the base plate, thus releasing the replacement film 18. The outer diameter surface of the connecting rod 22... A spring 21 is sleeved on the connecting rod 22, one end of which is engaged with a limit block 23. Each side of the limit block 23 is equipped with a locking head 24 for locking. A snap ring 25 is installed at the top of the connecting rod 22. Then, by separating the replacement membrane 18 and after the replacement membrane 18 is replaced, since the sealing ring of the new membrane cannot fit perfectly, the membrane cover 1801 of the replacement membrane 18 is manually squeezed to release the locking head 24, so that the snap ring 25 is inserted into the slot of the membrane cover 1801 and the replacement membrane 18 is limited.

[0031] In a preferred embodiment, a membrane cover 1801 is connected to the side of the replacement membrane 18. Both sides of the membrane cover 1801 are provided with grooves for connecting with the snap ring 25. A sealing ring is sleeved at the edge of the membrane cover 1801. When the replacement membrane 18 is inserted into the box 1201 and the blocking bracket 19 is reset, the membrane cover 1801 is pressed to fit against the box 1201. The membrane cover 1801 of the replacement membrane 18 is used to fit against the box 1201, and the membrane cover 1801 and the box 1201 are sealed by the sealing ring.

[0032] In a preferred embodiment, the lifting bracket 3 includes two sets of hydraulic rods 4. The top ends of the two sets of hydraulic rods 4 are equipped with mounting joints 5 for snap-fitting. The two sets of hydraulic rods 4 in the lifting bracket 3 are the driving ends and are connected to the mounting plate 6 through the mounting joints 5 connected to the hydraulic rods 4. The mounting plate 6 is bolted to the top end of the mounting joint 5. The mounting plate 6 is provided with a connecting bracket 7 located directly below the housing 1. The connecting bracket 7 is connected to the cathode plate 8. After the connection is completed, the hydraulic rods 4 push the mounting plate 6 to move up and down. At this time, the cathode plate 8 connected to the mounting plate 6 through the connecting bracket 7 can be driven by the hydraulic rods 4 and move up and down. When the cathode plate 8 moves up and down, the scraper fixed on the housing scrapes the dirt generated on the cathode plate during the processing.

[0033] In a preferred embodiment, an acidic water inlet 15 is provided at the edge of the housing 1. Several sets of conveying pipes 16 are arranged above the acidic water inlet 15. For purification treatment, acidic liquid is required for internal processing. The acidic water inlet 15 is used for the acidic liquid. The pipe body of the acidic water inlet 15 has a corrosion-resistant structure. Then, the conveying pipes 16 are arranged sequentially above the acidic water inlet 15. Each conveying pipe 16 is connected to a ball valve 1601. Each conveying pipe 16 is equipped with a ball valve 1601, so that each conveying pipe 16 exists independently and the conveying status of the corresponding conveying pipe 16 can be adjusted at any time according to the usage.

[0034] In a preferred embodiment, a water tank 14 is provided on the side of the housing 1 away from the delivery pipe 16. An aeration head 17 is arranged inside the water tank 14, and an acidic outlet 1401 for discharging acidic liquid is provided below the water tank 14. The aeration head 17 supplies air to the bottom of the housing 1. The aeration head 17 is specifically a suction pump structure, which agitates the dirt in the bottom water source and prevents the dirt from settling to the bottom. A water pump body is connected to the acidic outlet 1401 inside the water tank 14. The water pump body inside the water tank 14 is also a corrosion-resistant structure. When the acidic liquid is purified, it is adsorbed by the water pump body and discharged through the acidic outlet 1401, thereby completing the discharge of the acidic liquid.

[0035] In a preferred embodiment, a first alkaline water inlet 11 is provided on the side of the lifting bracket 3, and a first alkaline water outlet 13 is provided on the side of the tank 1 away from the first alkaline water inlet 11. A liquid level regulating baffle 26 is placed against the inner wall of the tank 1 at the first alkaline water outlet 13. The outer surface of the liquid level regulating baffle 2601 is provided with a mounting hole 2601. When adjusting the liquid level in the tank 1, the height of the liquid level regulating baffle 26 is moved so that the blocked first alkaline water outlet 13 is discharged as the liquid level regulating baffle 26 moves. As the height of the liquid level regulating baffle 26 gradually increases, its blocking area on the first alkaline water outlet 13 decreases, thereby increasing the flow rate of the discharged liquid. Both the first alkaline water inlet 11 and the first alkaline water outlet 13 are output channels for alkaline water, mainly used for discharging and transporting alkaline water for the treatment equipment.

[0036] In a preferred embodiment, a backwash port 10 is provided on the side of the acidic water outlet 1401, and a drain port 9 for discharging sewage is provided at the bottom of the tank 1. By inputting high-pressure gas or water flow into the backwash port 10, the filter element, pipe and other components in the equipment are backwashed to remove deposited impurities, dirt or blockages.

[0037] In this embodiment, the hydraulic rod 4, ball valve 1601, and air-venting head 17 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, so we will not go into detail here.

[0038] The working process of this utility model is as follows: First, the support bracket 2 is used to support the overall structure of the box 1, while the lifting bracket 3 moves the cathode plate and makes the anode plate and cathode plate come into contact. Together with the semi-permeable membrane in the membrane box, the substances in the water source are purified and adsorbed. By pulling the locking head 24, the limit on the connecting rod 22 is released. Then, by pulling the limit block 23, the locking head 24 is re-inserted into the base plate, thus completing the release of the replacement membrane 18.

[0039] Then, the two sets of hydraulic rods 4 in the lifting bracket 3 are the driving ends. They are connected to the mounting plate 6 through the mounting joints 5 connected to the hydraulic rods 4. After the connection is completed, the hydraulic rods 4 push the mounting plate 6 to move up and down. At this time, the cathode plate 8 connected to the mounting plate 6 through the connecting bracket 7 can be driven by the hydraulic rods 4 and scrape the dirt generated on the cathode plate during the processing.

[0040] For purification, the tank 1 requires acidic liquid for treatment. An acidic inlet 15 is provided for the acidic liquid. The pipe of the acidic inlet 15 has a corrosion-resistant structure. Then, delivery pipes 16 are arranged above the acidic inlet 15. Each delivery pipe 16 is equipped with a ball valve 1601, so that each delivery pipe 16 is independent and the delivery status of the corresponding delivery pipe 16 can be adjusted at any time according to the usage. The pump body in the water tank 14 also has a corrosion-resistant structure. After the acidic liquid is purified, it is adsorbed by the pump body and discharged through the acidic outlet 1401, thus completing the discharge of the acidic liquid.

[0041] The first alkaline water inlet 11 and the first alkaline water outlet 13 are both output channels for alkaline water, mainly used to discharge and transport alkaline water for the treatment equipment. By inputting high-pressure gas or water flow into the backwash port 10, the filter element, pipe and other components in the equipment are backwashed to remove deposited impurities, dirt or blockages. The above is the working principle of this acid-base separation type fully automatic electrochemical water treatment device.
