DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In this embodiment, preferably, a gap is left between the positive electrode cylinder 11 and the negative electrode cylinder 12, and water 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 energized, an electric field is generated between the positive electrode cylinder 11 and the negative electrode cylinder 12.

[0027] Example 2, reference Figure 1-Figure 7 This embodiment is based on the previous embodiment, and differs from the previous embodiment in that.

[0030] Reference Figure 3There are multiple electromagnets 112, and the fixed tube 111 is slidably connected to the iron tube 113. There are multiple iron tubes 113 corresponding to the electromagnets 112, and both ends of the iron tube 113 are fixedly connected to the first piston head 114.

[0031] In this embodiment, preferably, when multiple electromagnets 112 are sliding, the magnetic field position can be changed, so that the magnetic flux lines cut the water flow, which is beneficial to improve the efficiency of catalytic oxidation and optimize the water quality; multiple electromagnets 112 can be combined together to form a stronger magnetic field to catalytically oxidize stubborn organic pollutants in the water flow, or 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, and the fixed pipe 111 between the integrally movable iron pipe 113 is filled with gas, which can push the integrally movable iron pipe 113 to be evenly separated inside the fixed pipe 111 under the action of the gas pressure, and each electromagnet 112 is evenly separated with the iron pipe 113 under the action of the magnetic field.

[0033] In this embodiment, the two ends of the fixed pipe 111 are respectively connected to the inside of the cylinder 123 through the first connecting pipe 121 and the second connecting pipe 122. The parts of the cylinder 123 near the two ends are filled with hydraulic oil. The hydraulic oil is pumped into the inlet pipe 127 by using an existing hydraulic pump. The hydraulic oil pushes the fourth piston head 1242 and the fifth piston head 1252 to move in the direction close to the two 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 Figure 5 The movement of the left side of the middle part squeezes the hydraulic oil in the cylinder 123, and the fifth piston head 1252 drives the second movable rod 1251 to move, and the second movable rod 1251 drives the third piston head 125 to move.

The hydraulic oil at the two ends of the fixed tube 111 is squeezed, and each iron tube 113 and the first piston heads 114 at both ends form an integrally movable iron tube 113. The gas filled inside the fixed tube 111 between the integrally movable iron tubes 113 compresses the distance between each adjacent first piston heads 114, thereby attracting multiple electromagnets 112 to merge together to form a stronger magnetic field, catalyzing and oxidizing the more stubborn organic pollutants in the water flow. At this time, the hydraulic oil pressure at both ends of the fixed tube 111 reaches a balanced state. During installation, move the cylinder 123 and the control tube 126 along Figure 5 The cross-section shown is cut open, and the parts inside the cylinder barrel 123 and the control barrel 126 are first installed, and then the cylinder barrel 123 and the control barrel 126 are welded together to form a complete whole.

[0035] In this embodiment, preferably, the inlet pipe 127 is made of steel pipe, which is a hard material. When the hydraulic oil pressure at both ends of the fixed pipe 111 reaches a balanced state, the inlet pipe 127 is controlled to slide inside the through groove 1231, and the inlet pipe 127 can drive the control cylinder 126 to slide inside the first fixed ring 1232, and the second piston head 124 and the third piston head 125 at both ends of the control cylinder 126 also move accordingly. Under the action of the hydraulic oil, the first piston head 114 inside the fixed pipe 111 can be driven to move up and down, and then drive the multiple electromagnets 112 combined together to move, which can change the magnetic field position, so that the magnetic flux lines cut the water flow, which is conducive to improving the efficiency of catalytic oxidation and optimizing the water quality of the effluent. Under the synergistic effect of the magnetic field and the electric field, the water flow is subjected to two-phase catalytic oxidation to improve the treatment efficiency.

[0036] Reference Figure 5 The cylinder 123 is fixedly connected to one end of the gas collecting pipe 1233 near the two ends, and the other end of the gas collecting pipe 1233 is threadedly connected to the cover 1234.

[0037] In this embodiment, preferably, the gas that penetrates into the cylinder 123 can be collected inside the gas collecting pipe 1233, and the gas can be released by unscrewing the cover 1234.

[0039] In this embodiment, preferably, the existing motor is fixedly connected to the end of the screw rod 52 which is rotatably connected and passes through the second fixed plate 54. When the motor is working, it can drive the screw rod 52 to rotate. The screw rod 52 drives the movable seat 51 to move under the action of the thread. The movable seat 51 drives the control cylinder 126 to slide inside the first fixed ring 1232 through the inlet pipe 127. When the hydraulic oil pressure at both ends of the fixed pipe 111 reaches a balanced state, the inlet pipe 127 is controlled to slide inside the through groove 1231, and the second piston head 124 and the third piston head 125 at both ends of the control cylinder 126 also move accordingly. Under the action of the hydraulic oil, the first piston head 114 inside the fixed pipe 111 can be driven to move up and down, thereby driving the movement of multiple electromagnets 112 combined together, which can change the position of the magnetic field so that the magnetic flux lines cut the water flow, which is beneficial to improving the efficiency of catalytic oxidation and optimizing the effluent water quality.
