DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0028] Reference Figure 1-4 , a wastewater treatment equipment, comprising:

[0029] Processing box 1, water inlet pipe 2, drain pipe 4, mounting plate 6, electrode plate 8 and switch assembly and other parts.

[0030] First, the treatment box 1 serves as the main body of the entire treatment equipment, and guide rods 5 are fixedly installed on both sides of it to support and guide the lifting and lowering movement of the mounting plate 6. The mounting plate 6 is slidably connected to the guide rods 5 to ensure that the mounting plate 6 can move up and down smoothly in the treatment box 1. Two electrode plates 8 are provided at the bottom of the mounting plate 6. These two electrode plates 8 are made of different materials, one is the anode and the other is the cathode. According to the different components contained in the wastewater, the electrode plates 8 of appropriate materials can be selected for use as needed. At the same time, the two electrode plates 8 are respectively connected to the positive and negative poles of the external power supply to achieve electrolytic treatment of the wastewater.

[0031] The water inlet pipe 2 and the drain pipe 4 are fixedly installed on both sides of the treatment box 1 respectively. The water inlet pipe 2 is used to inject the wastewater to be treated into the treatment box 1, and the drain pipe 4 is used to discharge the treated wastewater.

[0032] To automatically control the addition and discharge of wastewater, this embodiment also incorporates two switch assemblies. Specifically, each switch assembly includes a sealed rotary disc 15, which is mounted on the inner wall of the treatment tank 1 for sealed rotation. The rotary disc 15 has an offset through-hole 16 formed therein. The sealed rotary disc 15 is connected to a first synchronous pulley 17 via a first rotating shaft 14. The first synchronous pulley 17 is in transmission connection with a second synchronous pulley 18 via a timing belt. The second synchronous pulley 18 is fixedly mounted on a second rotating shaft 19. A gear 20 is fixedly mounted on the outer wall of the second rotating shaft 19. The gear 20 meshes with a rack 21, which slides against the outer wall of the treatment tank 1 and is fixedly mounted on the bottom of the mounting plate 6.

[0033] In addition, a cylinder 3 is fixedly installed on one side of the processing box 1. One end of the piston rod of the cylinder 3 is fixedly connected to the bottom of the mounting plate 6, and is used to drive the mounting plate 6 and the electrode plate 8 thereon to perform lifting and lowering movements. When the mounting plate 6 is raised or lowered, the gear 20 and the second rotating shaft 19 are driven to rotate by the rack 21, and then the first rotating shaft 14 and the sealing turntable 15 can be driven to rotate by the synchronous belt. When the through hole 16 is aligned with the water inlet pipe 2 or the drain pipe 4, water is allowed to flow through; when the through hole 16 is misaligned, the water flow is blocked. By controlling the lifting height of the mounting plate 6, the water inlet pipe 2 and the drain pipe 4 can be automatically opened and closed.

[0034] A mounting groove 7 is provided on the top of the mounting plate 6, and screws 9 are fixedly installed on the tops of the two electrode plates 8. After the screws 9 pass through the mounting grooves 7, a limit plate 10 and a first nut 11 are sleeved on the outer wall of the screw 9. The electrode plates 8 are suspended and mounted on the mounting plate 6 by tightening the first nut 11. In order to connect the external power supply to the electrode plates 8, a connecting electrode sheet 13 is also sleeved on the screw 9, and a second nut 12 is tightened on top of the screw 9. The connecting electrode sheet 13 is tightly fitted on the screw 9 by squeezing and fixing the second nut 12 and the first nut 11, and is connected to the positive and negative poles of the external power supply through a wire to complete the conduction of the circuit.

[0035] This application can be used in the field of wastewater treatment technology, and can also be used in other fields applicable to this application. Example

[0037] In this embodiment, the through holes 16 inside the two sealing turntables 15 correspond to each other, and the two are respectively matched with one end of the adjacent water inlet pipe 2 and drainage pipe 4. The installation positions of the water inlet pipe 2 and the drainage pipe 4 are staggered to ensure that the entry and discharge of sewage do not occur at the same time.

[0038] In this embodiment, the mounting plate 6 is made of insulating material and the screw 9 is made of conductive material, such as copper, to ensure that the external power supply can stably supply power to the two electrode plates 8 and that the current is not likely to cause damage to surrounding equipment or personnel.

[0039] However, as is well known to those skilled in the art, the working principle and wiring method of the cylinder are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

At this time, the gear 20 can be driven to rotate by the movement of the rack 21, and then the sealing turntable 15 can be rotated by the synchronous belt drive, thereby completing the alignment of the water inlet pipe 2 with the adjacent through hole 16, allowing external wastewater to be injected, and at this time, the 15 on the other side will close the drain pipe 4 to ensure that the sewage will not be discharged directly; then the external water source is driven to be injected into the treatment box 1 through the water inlet pipe 2, and then the control The mounting plate 6 is lowered again to complete the closure of the water inlet pipe 2, thus completing the preparation for wastewater treatment; then the external power supply is started to transmit the current to the electrode plate 8 through the connecting electrode sheet 13, and the two electrode plates of different materials form an electrolytic environment in the wastewater to electrochemically oxidize the wastewater; at the same time, the power supply output voltage and current intensity are adjusted according to the properties of the wastewater and the treatment requirements to achieve the best treatment effect; when the wastewater in the treatment box 1 is treated to a certain extent, the mounting plate 6 is driven to descend by the cylinder 3. At this time, the two sealing turntables 15 are rotated again, and the through hole 16 in the sealing turntable 15 on the other side is aligned with the drain pipe 4, allowing the treated wastewater to be discharged; when the treated wastewater is discharged, the mounting plate 6 is controlled to be lifted again, and new wastewater can be added to the treatment box 1 again according to the above operation; repeating the above steps can realize continuous electrochemical oxidation treatment of wastewater and ensure good continuity of wastewater treatment.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
