[0012] Compared with the prior art, this utility model provides a titanium anode reversal device for water treatment, which has the following advantages:

[0013] 1. In this water treatment field, a titanium anode reversal device is used. The reversal device continuously reverses the electrode direction of the two electrolytic plates during operation, turning the plate that was originally the anode into the cathode, inhibiting its oxidation reaction. At this time, the plate is in a cathodic protection state, with electrons enriched on the surface, preventing ion migration and corrosion by corrosive media.

This allows the sewage to pass fully through the gap between the two electrolytic plates, thereby improving the uniformity of sewage electrolysis treatment. Furthermore, the water flow impacting the plates can remove the corrosion products deposited on the plate surface, preventing the accumulation of corrosion products from forming localized micro-cells that accelerate corrosion, thus improving the treatment efficiency.

The stirring rod 61 drives the stirring plate 62 to rotate, which accelerates the flow of sewage inside the treatment cylinder 1.

[0027] Furthermore, the reversing device 8 includes a support ring frame 81, an annular mounting base 82, an outer conductive ring seat 83, an inner conductive ring seat 84, a conductive contact plate 85, a separating mounting base 86, a rear conductive contact piece 87, a front conductive contact piece 88, and a power supply base 89. The support ring frame 81 is rotatably mounted to the right side wall of the processing cylinder 1 via bearings. The annular mounting base 82 is mounted to the right side of the support ring frame 81. Two annular grooves are formed on the outer wall of the annular mounting base 82. The outer conductive ring seat 83 and the inner conductive ring seat 84 are respectively installed inside the annular grooves formed on the outer wall of the annular mounting base 82. The elastic conductive contact plate 85 is mounted to the left side wall of the annular mounting base 82. There are two conductive contact plates 85. The front conductive contact plate 85 is electrically connected to the inner conductive ring seat 84 via a wire, and the rear conductive contact plate 85 is electrically connected to the outer conductive ring seat 83 via a wire. The separating mounting base 86 is mounted to the right side wall of the processing cylinder 1 and located on the support ring frame 81. The outer side is installed with the rear conductive contact 87 installed inside the rear side groove of the inner conductive ring seat 84. The left end of the rear conductive contact plate 85 contacts the surface of the rear conductive contact 87. The front conductive contact 88 is installed inside the front side groove of the inner conductive ring seat 84. The left end of the front conductive contact plate 85 contacts the surface of the front conductive contact 88. The right end of the rear conductive post 93 is connected to the rear conductive contact 87. The right end of the front conductive post 93 is connected to the front conductive contact 88. The power supply seat 89 is installed on the right side wall of the processing cylinder 1 and outside the annular mounting seat 82. The two power supply contacts of the power supply seat 89 contact the outer conductive ring seat 83 and the inner conductive ring seat 84 respectively to supply power.

The electrolysis device 9 is powered through the reversing device 8, and the direction of the power supply electrode is constantly changed.

[0028] Furthermore, the transmission device 7 includes a first gear 71, a reduction gear 72, an acceleration gear 73, and a meshing gear 74. The first gear 71 is rotatably mounted to the right side wall of the processing cylinder 1 via a bearing. The left end of the first gear 71 is connected to the right end of the power shaft 5 via a connecting rod. The reduction gear 72 is mounted to the right side wall of the processing cylinder 1 via a bracket, and the first gear 71 meshes with the reduction gear 72. The acceleration gear 73 is mounted to the right end of the reduction gear 72 via a support rod. The meshing gear 74 is mounted to the right side wall of the processing cylinder 1 via a bracket. The accelerating gear 73 meshes with the meshing gear 74. The inner wall of the support ring frame 81 is provided with teeth. The meshing gear 74 meshes with the support ring frame 81. The number of teeth of the reducing gear 72 is greater than the number of teeth of the first gear 71. The number of teeth of the first gear 71 is greater than the number of teeth of the accelerating gear 73. The first gear 71 drives the reducing gear 72 to rotate. The reducing gear 72 drives the accelerating gear 73 to rotate. During the transmission process, the speed is reduced. Finally, the accelerating gear 73 drives the support ring frame 81 to rotate at a low speed through the meshing gear 74.

[0029] Furthermore, there are four stirring rods 61 arranged in a circumferential array on the outside of the power shaft 5. The stirring plates 62 are inclined and installed on the outer surface of the stirring rods 61. The stirring plates 62 on the outer side of the upper and rear stirring rods 61 are inclined in the opposite direction to the stirring plates 62 on the outer side of the lower and front stirring rods 61. Through the stirring and cooperation of the stirring plates 62 with different inclination directions, the sewage is pushed to pass between the two electrolysis plates 91, thereby improving the uniformity of electrolysis.

[0030] In operation, wastewater is injected into the treatment cylinder 1 through the wastewater discharge pipe 3. The power motor 4 is started, which drives the power shaft 5 to rotate. The power shaft 5 drives the stirring plate 62 to rotate through the stirring support rod 61. The stirring plate 62 pushes the water flow in a direction perpendicular to the axis of the treatment cylinder 1, so that the wastewater on the outer side can also pass between the two electrolytic plates 91 for electrolysis. The accelerated water flow also improves the scouring effect on the surface of the electrolytic plates 91. At the same time, the power supply base 89 connects the positive and negative terminals of the outer conductive ring seat 83 and the inner conductive ring seat 84, respectively. The outer conductive ring seat 83 and the inner conductive ring seat 84 are connected to the rear conductive contact piece 87 and the front conductive contact piece 88, respectively, through the two conductive contact plates 85. The rear conductive contact piece 87 and the front conductive contact piece 88 are connected to different electrodes of the two electrolytic plates 91 through the conductive post 93 for electrolysis. When the power shaft 5 rotates, it drives the first gear 7. 1. Rotation: The first gear 71 drives the reduction gear 72 to rotate at a reduced speed. The reduction gear 72 drives the acceleration gear 73 to rotate. The acceleration gear 73 drives the support ring frame 81 to rotate through the meshing gear 74. The support ring frame 81 drives the annular mounting seat 82 to rotate. The annular mounting seat 82 drives the conductive contact plate 85 to rotate, causing the two conductive contact plates 85 to alternately change their connection state with the rear conductive contact 87 and the front conductive contact 88. This causes the direction of the current electrode transmitted to the rear conductive contact 87 and the front conductive contact 88 to continuously change. Consequently, the direction of the current transmitted to the two electrolytic plates 91 through the conductive post 93 continuously changes, thus causing the positive and negative poles of the two electrolytic plates 91 to continuously change. By changing the positive and negative poles, the corrosion effect of the electrolytic plates 91 is reduced, and the service life of the electrolytic plates 91 is improved. The water after electrolysis is discharged through the sewage discharge pipe 31.
