Detailed implementation manners

[0026] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0027] Example 1, refer to Figures 1-3, this embodiment provides an SME-DT high-efficiency catalytic oxidation wastewater treatment device, including a catalytic oxidation tank 1. The catalytic oxidation tank 1 includes a positive electrode cylinder 11, a negative electrode cylinder 12, a first baffle 13, a second baffle 14, a first disc 15 and a second disc 16. One end of the positive electrode cylinder 11 and the negative electrode cylinder 12 are respectively fixedly connected to the first baffle 13, and the other end of the positive electrode cylinder 11 and the negative electrode cylinder 12 are respectively fixedly connected to the second baffle 14. And the negative electrode cylinder 12 is sleeved outside the positive electrode cylinder 11. The inner wall of the negative electrode cylinder 12 is fixedly connected to the first disc 15, and there is a gap between the axis of the first disc 15 and the positive electrode cylinder 11. The outer wall of the positive electrode cylinder 11 is fixedly connected to the second disc 16, and there is a gap between the second disc 16 and the negative electrode cylinder 12. One end of the first baffle 13 is communicated with one end of the water inlet pipe 131, and one end of the second baffle 14 is connected to one end of the water outlet pipe 141; a fixed pipe 111 is fixedly connected to the inner wall of the positive electrode cylinder 11, and an electromagnet 112 is slidably connected to the outer wall of the fixed pipe 111.

[0028] Preferably in this embodiment, there is a gap between the positive electrode cylinder 11 and the negative electrode cylinder 12, and water flow can pass through the gap between the positive electrode cylinder 11 and the negative electrode cylinder 12. After the positive electrode cylinder 11 and the negative electrode cylinder 12 are electrified, an electric field is generated between the positive electrode cylinder 11 and the negative electrode cylinder 12. The water flow to be treated can enter the inside of the negative electrode cylinder 12 through the water inlet pipe 131, and the treated water flow is discharged from the water outlet pipe 141. A plurality of first discs 15 and second discs 16 are arranged alternately. The water flow sequentially passes through the gap between the axis of the first disc 15 and the positive electrode cylinder 11 and the gap between the second disc 16 and the negative electrode cylinder 12. The water flow is in full contact with the surfaces of the first disc 15 and the second disc 16, which is beneficial to improving the efficiency of catalytic oxidation and optimizing the water quality of the effluent. Moreover, the electromagnet 112 can slide on the outer wall of the fixed pipe 111. A magnetic field can be generated by the electromagnet 112.

[0030] Referring to Figure 1 , it further includes a housing 2, a base 3 and a top seat 4. The bottom of the housing 2 is fixedly connected to the base 3, the catalytic oxidation tank 1 is located inside the housing 2, and the top of the housing 2 is fixedly connected to the top seat 4.

[0031] Preferably in this embodiment, the base 3 and the top seat 4 can play a role in fixing and supporting the catalytic oxidation tank 1, and a plurality of catalytic oxidation tanks 1 are provided. The housing 2 can play a role in protecting the catalytic oxidation tank 1.

[0032] Referring to Figure 3, there are multiple electromagnets 112 provided. The iron pipe 113 is slidably connected inside the fixed pipe 111. There are multiple iron pipes 113 corresponding to the electromagnets 112. Both ends of the iron pipe 113 are fixedly connected to the first piston heads 114 respectively.

[0033] Preferably in this embodiment, when the multiple electromagnets 112 slide, they can change the magnetic field position, enabling the magnetic induction lines to cut the water flow, which is beneficial to improving the efficiency of catalytic oxidation and optimizing the water quality of the effluent. The multiple electromagnets 112 can be combined together to form a stronger magnetic field for catalytic oxidation of stubborn organic pollutants in the water flow, or the multiple electromagnets 112 can be evenly separated to form a uniform magnetic field in the catalytic oxidation tank 1, giving full play to the synergistic effect of the magnetic field and the electric field. Each iron pipe 113 and the first piston heads 114 at both ends form an integrally movable iron pipe 113. The inside of the fixed pipe 111 between the integrally movable iron pipes 113 is filled with gas, and under the action of the gas pressure, it can push the integrally movable iron pipes 113 to be evenly separated inside the fixed pipe 111, and each electromagnet 112 is evenly separated along with the iron pipe 113 under the action of the magnetic field.

[0034] Refer to Figure 6 , both ends of the fixed pipe 111 are respectively connected to one end of the first connecting pipe 121 and the second connecting pipe 122. The other end of the first connecting pipe 121 is connected to one end of the cylinder barrel 123, and the other end of the second connecting pipe 122 is connected to the other end of the cylinder barrel 123. The inner wall of the cylinder barrel 123 is slidably connected to the second piston head 124 and the third piston head 125. One end of the first movable rod 1241 is fixedly connected to the second piston head 124. The other end of the first movable rod 1241 is fixedly connected to one side of the fourth piston head 1242. The fourth piston head 1242 is slidably connected to the inner wall of the control cylinder 126. The other side of the fourth piston head 1242 is fixedly connected to the limit post 1243;

[0035] One end of the second movable rod 1251 is fixedly connected to the third piston head 125. The other end of the second movable rod 1251 is fixedly connected to the fifth piston head 1252, which is slidably connected to the inner wall of the control cylinder 126. The control cylinder 126 is fixedly connected to the inlet pipe 127.

[0036] Preferably in this embodiment, both ends of the fixed pipe 111 are internally communicated with the cylinder barrel 123 through the first connecting pipe 121 and the second connecting pipe 122. The parts of the cylinder barrel 123 near both ends are filled with hydraulic oil. The existing hydraulic pump is used to pump hydraulic oil into the inlet pipe 127. The hydraulic oil pushes the fourth piston head 1242 and the fifth piston head 1252 to move towards the directions close to both ends of the control cylinder 126. The fourth piston head 1242 drives the first movable rod 1241 to move, and the first movable rod 1241 drives the second piston head 124 to move Figure 5 to the left in theFigure 5 The movement to the right in the middle squeezes the hydraulic oil inside the cylinder barrel 123, and acts on both ends of the fixed pipe 111 through the first connecting pipe 121 and the second connecting pipe 122. Due to the extrusion of the hydraulic oil at both ends of the fixed pipe 111, each iron pipe 113 and the first piston heads 114 at both ends form an integrally movable iron pipe 113. The gas filled inside the fixed pipe 111 between the integrally movable iron pipes 113 compresses the distance between adjacent first piston heads 114, thereby attracting multiple electromagnets 112 to merge together to form a stronger magnetic field, which catalytically oxidizes the relatively stubborn organic pollutants in the water flow. At this time, the hydraulic oil pressure at both ends of the fixed pipe 111 reaches an equilibrium state. During installation, cut the cylinder barrel 123 and the control cylinder 126 along Figure 5 the shown cross-section, first install the parts inside the cylinder barrel 123 and the control cylinder 126, and then weld the cylinder barrel 123 and the control cylinder 126 together to form a complete whole.

When the electric motor works, it can drive the lead screw 52 to rotate. Under the action of the thread, the lead screw 52 drives the movable seat 51 to move. The movable seat 51 drives the control cylinder 126 to slide inside the first fixing ring 1232 through the inlet pipe 127.
