Detailed Description
The following detailed description of the present application is provided in conjunction with the accompanying drawings, and it is to be understood that the following detailed description is merely illustrative of the application and is not to be construed as limiting the scope of the application, since numerous insubstantial modifications and adaptations of the application will be to those skilled in the art in light of the foregoing disclosure.
Example 1
As shown in fig. 1-6, an electrolytic treatment device for high-salt organic wastewater comprises a rotary table 1, wherein a motor 2 for driving the rotary table 1 to rotate is arranged on the rotary table 1, more than two electrolytic mechanisms are equidistantly arranged on the rotary table 1 along the circumferential direction of the rotary table 1, and one group of electrolytic mechanisms is positioned below the rotary table 1 and positioned in the wastewater;
the electrolysis mechanism comprises a bracket 3 and a guide rod 4 which are arranged on the turntable 1, an electrode 5 which slides along the length direction of the guide rod 4 is arranged at one end of the guide rod 4, which is far away from the turntable 1, a reset spring 6 which drives the electrode 5 to move is arranged at one end of the electrode 5, which is far away from the turntable 1, a pressure sensing unit 7 which detects the weight of the electrode 5 is arranged at one end of the reset spring 6, which is far away from the turntable 1, and the pressure sensing unit 7 is arranged on the bracket 3;
the turntable 1 is provided with a controller, and the controller is configured to:
the controller receives the weight value of the electrode 5 sent by the pressure sensing unit 7 and compares the weight value with a set reference value, and when the weight value of the electrode 5 is lower than the reference value, the motor 2 is controlled to start, so that the motor 2 drives the adjacent electrolysis mechanism to be immersed into the wastewater and reach the working position, and then the motor 2 stops working.
In the above embodiment, the motor 2 is fixed above the electrolytic cell, and the turntable 1 is rotatably installed above the electrolytic cell, so that the turntable 1 can be normally rotated. In the electrolysis process, the lowest group of electrolysis mechanisms is positioned in the wastewater, and the rest electrolysis mechanisms are positioned above the wastewater. During electrolysis, current is generated at the electrode 5, and the strong current enables toxic and harmful substances to undergo oxidation-reduction reaction, so that pollutants in water are removed, and COD in the wastewater can be effectively reduced by an electrolysis method. In the electrolysis process, the electrode 5 gradually corrodes, so that the weight of the electrode 5 is reduced, the extrusion force applied to the return spring 6 is reduced, the return spring 6 drives the electrode 5 to move upwards, and meanwhile, the weight value of the electrode 5 measured by the pressure sensing unit 7 is reduced. When the electrode 5 corrodes to a certain extent and reaches a set value for replacement, the pressure sensing unit 7 reaches a set value for measurement, at the moment, the pressure sensing unit 7 sends a signal to the controller, and the controller controls the motor 2 to start, so that the motor 2 drives the turntable 1 to rotate, a next group of electrolysis mechanisms can be replaced to enter the wastewater, and the used electrolysis mechanisms rotate to the water until the plurality of electrolysis mechanisms are uniformly replaced after being used.
As a further scheme of the invention, the electrolysis mechanism further comprises more than two first springs 8 arranged on the turntable 1, a cleaning ring 9 for cleaning the electrode 5 is fixed at one end of each first spring 8 far away from the turntable 1, a mounting groove is formed in the bracket 3, a second spring 10 is arranged in the mounting groove, a clamping block 11 with magnetism for controlling the position of the cleaning ring 9 is arranged on the second spring 10, and a magnetic block 12 with the same magnetism as the clamping block 11 and used for changing the position of the clamping block 11 is arranged on the electrode 5.
In the above embodiment, the electrode 5 will corrode during the working process, so that the electrode 5 moves upwards along the guide rod 4, and when the electrode 5 moves to the set position, the repulsive force applied by the magnetic block 12 on the electrode 5 to the clamping block 11 makes the clamping block 11 enter the mounting groove, so that the first spring 8 is in a free state. The first spring 8 drives the cleaning ring 9 to move downwards rapidly, and the surface of the electrode 5 is cleaned in the moving process of the cleaning ring 9. The cleaning ring 9 is in contact with the surface of the electrode 5 through the inner side wall with soft property, and can clean the surface of the electrode 5 under the condition that the diameter of the surface of the electrode 5 is uneven, and the accumulated adhesion objects on the surface of the electrode 5 are scraped off.
As a further scheme of the invention, a collecting ring 13 which corresponds to the cleaning ring 9 and is used for scraping suspended matters on the surface of the electrode 5 is arranged on the support 3, and a collecting groove 14 for collecting the suspended matters is arranged on one side, close to the turntable 1, of the collecting ring 13.
As a further scheme of the invention, a storage tank 15 for temporarily storing suspended matters is arranged on one side of the cleaning ring 9 away from the turntable 1, and the storage tank 15 is C-shaped.
In the above embodiment, when the cleaning ring 9 passes through the electrode 5 and is located at one side of the return spring 6, the cleaning ring 9 contacts with the collecting ring 13 at this time, and the suspended matters collected on the surface of the cleaning ring 9 enter into the collecting groove 14 of the collecting ring 13 to be temporarily stored, so as to avoid the suspended matters from re-entering into the waste water to pollute the waste water. The cleaning ring 9 and the collecting ring 13 can be made of magnetic materials with different magnetic properties, so that the cleaning ring and the collecting ring are tightly attached to each other, and suspended matters are prevented from entering wastewater.
Wherein, clearance ring 9 probably causes the suspended solid to scatter in the removal in-process and gets into waste water, through being provided with stock chest 15, the suspended solid that scrapes from electrode 5 gets into stock chest 15 and temporarily stores, and the C font structure of stock chest 15 can effectively prevent the scatter of suspended solid to reduce the quantity of suspended solid in the waste water.
As a further scheme of the invention, a hole is arranged on the guide rod 4, and a limiting body 16 for limiting the movement of the electrode 5 is arranged at the hole.
As a further aspect of the present invention, the limiting body 16 is sucrose or sodium chloride.
In the above embodiment, the electrode 5 above the wastewater may pull the pressure sensing unit 7 under the action of gravity, so that the pressure sensing unit 7 generates an alarm to send a signal by mistake, although whether the trigger is normal or false can be judged by adjusting the holding time of the pressure measured by the pressure sensing unit 7, and avoiding the occurrence of the problem ensures that the invention can complete the work better. By arranging the limiting body 16 made of sucrose or sodium chloride to be plugged into the hole, the movement of the electrode 5 is blocked, and the electrode 5 which does not enter the wastewater cannot move, so that false alarm is avoided. When the electrolysis mechanism enters the waste water, the limiting body 16 also synchronously enters the water, and the limiting body 16 is made of a material which is easy to dissolve in the water, so that the limiting body 16 is quickly dissolved in the water after entering the waste water, and the electrode 5 is restored to the movable state, thereby ensuring the normal use of the electrode 5 and avoiding the occurrence of false alarm.

S3: the electrode 5 is gradually corroded in the use process of the electrolytic treatment device, the electrode 5 is driven by the reset spring 6 to be close to the rotary table 1, the total weight of the electrode 5 is reduced under the corrosion condition, the pressure sensing unit 7 triggers the controller after the weight of the electrode 5 is measured to be lower than a reference value, the controller controls the motor 2 to start, and the motor 2 drives the rotary table 1 to rotate, so that the adjacent electrolytic mechanism rotates to a working position in wastewater; during electrolysis, current is generated at the electrode 5, and the strong current enables toxic and harmful substances to undergo oxidation-reduction reaction, so that pollutants in water are removed, and COD in the wastewater can be effectively reduced by an electrolysis method.
