Description

Technical Field

[0001] This utility model belongs to the field of electrochemical water treatment technology, specifically relating to a cathode plate and an electrochemical water processor using the same. Background Technology

[0002] Electrochemical water treatment typically involves installing cathode and anode plates inside the water treatment device. When electricity is applied, an electrochemical reaction occurs on the cathode plate to generate hydroxide ions, which then react with the anions and cations in the water to be treated to form insoluble substances, which eventually adhere to the cathode surface to form a scale layer. Therefore, the structure of the cathode plate assembly is a crucial factor affecting the efficiency and cost of electrolysis.

[0003] The existing cathode plate has the following problems: because the cathode plate is a flat plate structure, the mass transfer is slow and the scale adsorption speed is slow. Moreover, the welding fixing method is prone to deformation, resulting in uneven adsorption and the scale that is not soft. The scale layer is not thoroughly removed by vibration, which ultimately reduces the service life of the equipment and affects the electrolysis efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model designs a cathode plate and an electrochemical water processor that installs the cathode plate. By designing the structure of the cathode plate, the scale layer on the surface of the cathode plate can be effectively removed, thereby improving the water treatment effect.

[0005] To achieve the above objectives, this utility model provides a cathode plate with multiple elongated holes in the middle. A first connecting plate, a second connecting plate, and a third connecting plate are spaced apart at one end of the cathode plate. The ends of the first and third connecting plates have first bent edges bent in the same direction, and the second connecting plate has second bent edges bent in the opposite direction. The cathode plate is fixed to the water processor housing by bolts through screw holes on the first and second bent edges.

[0006] Furthermore, the cathode plate is connected to a vibration motor, which drives the cathode plate to vibrate at high frequency, thereby effectively removing the scale layer.

[0007] Furthermore, a first notch is opened on both sides of the cathode plate.

[0008] An electrochemical water processor includes a housing, a cathode plate, an anode plate as described above, and a power supply. The cathode plate and the anode plate are spaced apart within the housing, and the anode plate and the cathode plate are electrically connected to the power supply.

[0009] Furthermore, the tank includes an inlet end and an outlet end. The anode plate and cathode plate are arranged longitudinally along the water flow direction. An overflow trough is provided at the outlet end at a position where it is level with the cathode plate. An outlet is provided on the overflow trough. The water to be treated is pumped into the tank from the inlet end, flows from bottom to top along the anode plate and cathode plate to the overflow trough, and is fully treated by the anode and cathode plates before being discharged from the outlet.

[0010] Furthermore, the cathode plate is connected to a vibration motor. One vibration motor can be used to drive the cathode plate inside the box to vibrate, or each cathode plate can be connected to a small vibration motor.

[0011] Furthermore, a cathode plate fixing beam and an anode plate fixing beam are fixedly installed on the frame of the box, respectively for fixing the cathode plate and the anode plate. A vibration motor is also fixed on the cathode plate fixing beam.

[0012] Furthermore, rubber pads are installed at the connection between the cathode plate fixing beam and the frame to isolate vibration energy, thereby preventing and reducing the transmission of vibration energy to the water processor and protecting other components inside the tank.

[0013] Furthermore, flexible positioning rods are fixed to the bottom of both sides of the cathode plate and the anode plate. A second notch is opened on the anode plate at the position corresponding to the first notch. Multiple slots are arranged circumferentially on the outer side wall of the flexible positioning rod. The first notch and the second notch correspond to the slots to ensure that the cathode plate and the anode plate are fixed in position and do not contact each other, effectively isolating them during vibration and preventing short circuits caused by contact between the cathode and anode plates during vibration.

[0014] Furthermore, a conical opening is provided at the bottom of the housing, directly opposite the array cathode plate, for the vibration to dislodge and drain the scale layer.

[0015] The advantages of this utility model are: changing the cathode plate fixing method makes the cathode plate less prone to deformation, changing the cathode plate flat plate structure to a porous structure, making the water flow faster and the scale layer absorb faster and the scale formed is softer, and using vibration to remove the scale layer is easier to remove. Therefore, the overall treatment efficiency and effect of the water processor are improved. Attached Figure Description

[0031] Example 1

[0032] This embodiment provides a cathode plate 100, see [link / reference] Figure 1The cathode plate has multiple elongated holes 101 in the middle. A first connecting plate 102, a second connecting plate 103, and a third connecting plate 104 are spaced apart at one end of the cathode plate. The ends of the first and third connecting plates have first bent edges 105 that bend in the same direction, and the second connecting plate has second bent edges 106 that bend in the opposite direction. The cathode plate is bolted by screw holes on the first and second bent edges, which facilitates disassembly and prevents deformation.

[0033] Furthermore, the cathode plate is connected to a vibration motor, which drives the cathode plate to vibrate at high frequency, thereby effectively removing the scale layer.

[0034] Furthermore, a first notch 107 is formed on both sides of the cathode plate.

[0035] Example 2

[0036] This second embodiment provides an electrochemical water processor, including a housing (600, see...). Figure 6 (The dotted line indicates the location of the array unit), the cathode plate 100, the anode plate 200, and the power supply (not shown in the figure) of Embodiment 1. The cathode plate and the anode plate are arranged alternately in the box. The anode plate and the cathode plate are electrically connected to the power supply. The power supply connection methods are all existing technologies and will not be described in detail here.

[0037] The tank in this embodiment includes an inlet end 601 and an outlet end 602. The anode plate and cathode plate are arranged longitudinally along the water flow direction. An overflow trough 603 is provided at the position where the outlet end is flush with the height of the cathode plate. The overflow trough is provided with an outlet. The water to be treated is pumped into the tank from the inlet end, flows from bottom to top along the anode plate and cathode plate to the overflow trough, and is fully treated by the anode and cathode plates before being discharged from the outlet.

[0038] In this embodiment, the cathode plate is connected to a vibration motor (not shown in the figure). The vibration motor is fixed to the cathode plate fixing beam through the motor bolt hole 303, that is, a vibration motor is used to drive the cathode plate inside the box to vibrate.

[0039] In this embodiment, a cathode plate fixing beam 300 and an anode plate fixing beam 400 are fixedly installed on the frame of the box, respectively for fixing the cathode plate and the anode plate, and are arranged perpendicularly to the array of cathode plates and anode plates. A vibration motor is fixed on the cathode plate fixing beam. Multiple cathode plates are detachably fixed to the bottom of the cathode plate fixing beam by bolts on their first and second bending edges. The bolts pass through bolt hole 304 and bolt hole 302. The anode plate fixing beam 400 can be fixed to the outside of the cathode plate fixing beam 300 by angle steel.

[0040] In this embodiment, a rubber pad 301 is installed at the connection between the cathode plate fixing beam and the frame to isolate vibration energy, thereby avoiding or reducing the transmission of vibration energy to the water processor and protecting other components inside the tank.

[0041] In this embodiment, flexible positioning rods 500 are fixed at the bottom of both sides of the cathode plate and the anode plate. A second notch 201 is opened on the anode plate at the position corresponding to the first notch. Multiple slots 501 are arranged circumferentially on the outer side wall of the flexible positioning rod. The first notch and the second notch correspond to the slots to ensure that the cathode plate and the anode plate are fixed in position and do not contact each other.

[0042] In this embodiment, multiple arrays of anode and cathode plate units can be set according to the needs of wastewater treatment. A conical opening 604 is set at the bottom of the box directly opposite the position of the array of anode and cathode plate units for the scale layer that is shaken off to fall down and be discharged.

[0043] Example 3

[0044] This embodiment is largely the same as Embodiment 2, except that there are more than 300' cathode plate fixing beams, which can be fixed with the bending plate. Angle steel is used to fix the first bending plate, the second bending plate, and the third bending plate of the cathode plate respectively. The number of small vibration motors is the same as the number of cathode plates, and the small vibration motors 600' are set on the middle cathode plate fixing beam.

[0045] In summary, during use, water enters from the inlet located at the bottom of one side of the treatment tank, undergoes thorough treatment by the anode and cathode plates, and is discharged through the outlet at the overflow trough. The smaller unit area of ​​the cathode plate reduces water flow resistance, resulting in faster scale absorption. This allows impurities in the water to form a relatively soft scale layer that adheres to the cathode plate. Once the scale layer on the cathode plate reaches a thickness of two to three millimeters, the vibration motor operates, vibrating the cathode plate. Simultaneously, the scale layer peels off, and the vibration force causes it to quickly detach from the cathode plate. The detached scale layer is then discharged downwards along the conical opening. This structure of the present invention improves the scale removal effect and efficiency.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
