[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to an electrochemical water treatment device. Background Technology

[0002] Electrochemical water softening equipment can remove calcium and magnesium ions from water, but the resulting scale will accumulate on the electrode plates. When the scale on the electrode plates reaches a certain thickness, it needs to be cleaned in a timely manner to prevent the plates from becoming passivated.

[0003] In existing technologies, manual cleaning is generally used. During cleaning, the cathode plate and cathode plate are removed from the equipment, and then the plates are cleaned. After the plates are cleaned, they are reinstalled into the equipment. The plate cleaning efficiency is low, the labor intensity of the relevant personnel is high, and the frequent disassembly and reassembly of the plates can easily cause damage to the plates themselves. Summary of the Invention

A scraper is provided between adjacent cathode plates and anode plates. The tops of all scrapers are connected as one unit by a connecting frame. The connecting frame is connected to a drive mechanism. When the drive mechanism is activated, it drives the scraper to move along the gap between the cathode plate and the anode plate. The bottom of the box is provided with a first drain pipe, and the first drain pipe is provided with a first valve.

[0006] In some embodiments, the drive mechanism includes a guide rod, a lead screw, and a ball nut; The lead screw is rotatably mounted inside the housing and is set perpendicular to the connecting frame; one end of the lead screw passes through the side wall of the housing and extends outward, and is connected to the output shaft of the drive motor mounted on the housing; a ball nut is provided on the lead screw, and the ball nut is fixedly connected to the connecting frame; The lead screw has guide rods on both sides that are parallel to it, and the connecting frame has a sliding sleeve through which the guide rods pass.

Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0015] like Figure 1 , Figure 2 As shown, this application provides an electrochemical water treatment device, including a tank 1, a partition 2, a cathode plate 3, and an anode plate 4. The tank 1 is generally rectangular in shape and hollow inside. A water inlet 101 is provided at the bottom of one side of the tank 1, and a water outlet 102 is provided at the top of the other side. The partition 2 is provided inside the tank 1. The side of the partition 2 is L-shaped. The partition 2 divides the tank 1 into a treatment chamber 103 and a sedimentation chamber 104. The water inlet 101 is connected to the treatment chamber 103, and the water outlet 102 is connected to the sedimentation chamber 104.

[0016] The processing chamber 103 has slots 105 on its two opposite side walls. The size of the slots 105 matches the thickness of the cathode plate 3 or anode plate 4. The sides of the cathode plate 3 and anode plate 4 are respectively inserted into the slots 105 on both sides, thereby installing the cathode plate 3 and the anode plate 4 in the processing chamber 103. The cathode plate 3 and the anode plate 4 are alternately distributed. A scraper 5 is provided between adjacent cathode plates 3 and anode plates 4. The scraper 5 is arranged vertically, with its bottom flush with or lower than the bottom of the electrode plate, and its top higher than the top of the electrode plate. The sides of the scraper 5 are in contact with the sides of the cathode plate 3 and the anode plate 4, or there is a small gap between them. The tops of all the scraper 5 are connected as one unit by a connecting frame 6. The connecting frame 6 is connected to the driving mechanism 7. When the driving mechanism 7 is activated, it drives the scraper 5 to move along the gap between the cathode plate 3 and the anode plate 4.

[0017] The bottom of the box 1 is funnel-shaped, and a first drain pipe 8 is provided at the lowest point. A first valve 9 is provided on the first drain pipe 8.

[0018] When this device is used to treat wastewater, the wastewater drainage pipe is connected to the inlet 101. The wastewater to be treated is introduced into the treatment chamber 103 from the inlet 101. Then, the wastewater flows upward and passes through the gap between the cathode plate 3 and the anode plate 4. The cathode plate 3 and the anode plate 4 work, and the pollutants in the water undergo oxidation, reduction, flocculation, and flotation reactions under the action of the electric field, thereby purifying the wastewater. Afterward, the treated water overflows into the sedimentation chamber 104 and is finally discharged through the drain outlet.

[0019] When the scale buildup on the cathode plate 3 and anode plate 4 is thick and needs to be cleaned (generally when the scale thickness exceeds 2cm), the power supply to the cathode plate 3 and anode plate 4 is disconnected. The drive mechanism 7 then activates, using the connecting frame 6 to move the scraper 5 along the gap between the cathode plate 3 and anode plate 4, thus scraping off the scale. This achieves mechanized cleaning of the cathode plate 3 and anode plate 4, eliminating the need to remove them from the water treatment device, reducing the workload of relevant personnel, and improving the efficiency of plate cleaning. The scale scraped off the plates settles at the bottom of the treatment chamber 103. When there is a large amount of sediment at the bottom of the treatment chamber 103 and cleaning is required, the first valve 9 is opened, and the sediment at the bottom of the treatment chamber 103 is discharged through the first drain pipe 8, thus cleaning the treatment chamber 103.

[0020] Meanwhile, this application removes scale adhering to the electrode plates by moving the scraper 5 along the gap between the cathode plate 3 and the anode plate 4. Compared with cleaning the electrode plates by moving the scraper 5 up and down, this can effectively save the space occupied by the scale removal component, thereby effectively reducing the overall size of the device.

[0021] In this embodiment, as Figure 3 As shown, the drive mechanism 7 includes a guide rod 701, a lead screw 702, and a ball nut 703. The lead screw 702 is rotatably installed inside the housing 1 and is perpendicular to the connecting frame 6. One end of the lead screw 702 passes through the side wall of the housing 1 and extends outward, connecting to the output shaft of the drive motor 704 mounted on the housing 1. The drive motor 704 is a stepper motor or a servo motor. The ball nut 703 is provided on the lead screw 702 and is fixedly connected to the connecting frame 6. Thus, when the drive motor 704 rotates, it drives the lead screw 702 to rotate, and the lead screw 702 drives the ball nut 703 to move along the lead screw 702. The ball nut 703 drives all the scrapers 5 to move along the gap between the cathode plate 3 and the anode plate 4 through the connecting frame 6, thereby scraping off the scale attached to the electrode plates and realizing the mechanized cleaning of the electrode plates.

[0022] The lead screw 702 is provided with guide rods 701 parallel to it on both sides. The connecting frame 6 is provided with a sliding sleeve 705. The guide rods 701 pass through the sliding sleeve 705, so that the sliding sleeve 705 can move along the guide rods 701. The setting of the two guide rods 701 makes the movement of the connecting frame 6 and all the scrapers 5 more stable.

[0023] In some specific embodiments, the cross-section of the scraper is V-shaped, which helps to improve the structural strength of the scraper 5, making the scraper 5 less prone to deformation and bending. At the same time, when the scraper 5 removes the scale from the electrode plate, the scale will move towards the center along the inclined surface of the scraper 5, effectively preventing the scraped scale from getting stuck in the gap between the scraper 5 and the electrode plate, resulting in a cleaner cleaning.

[0024] In some specific embodiments, a filter screen is provided inside the water outlet 102. Through the filter screen, solid impurities in the water are effectively removed, thereby effectively improving the cleanliness of the water treated by this device.

[0025] In some specific implementations, such as Figure 4 As shown, the top of the sedimentation chamber 104 is provided with a guide plate 10 arranged vertically, and there is a gap between the bottom of the guide plate 10 and the bottom of the sedimentation chamber 104, thereby dividing the sedimentation chamber 104 into a U-shaped flow channel. When the water in the treatment chamber 103 overflows into the sedimentation chamber 104, the water flows along the U-shaped flow channel until it is discharged from the outlet 102. The guide plate 10 increases the distance that the water flows in the sedimentation chamber 104, allowing solid impurities in the water to settle for a sufficient time. At the same time, it effectively prevents water from being discharged directly from the outlet 102 without sedimentation, further improving the cleanliness of the discharged water.

[0026] In some specific embodiments, the bottom of the sedimentation chamber 104 is inclined and a second drain pipe 11 is provided at the lower end. A second valve 12 is provided on the second drain pipe 11. When there is a lot of sediment at the bottom of the sedimentation chamber 104, the second valve 12 is opened to discharge the sediment in the sedimentation chamber 104.

[0027] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
