Description

Technical Field

[0001] This utility model relates to the field of electrode plate anti-passivation technology, specifically an electrochemical wastewater anti-passivation device. Background Technology

[0002] Wastewater electrolysis treatment refers to the application of electrolysis to purify wastewater by converting harmful substances in the original wastewater into harmless substances through oxidation and reduction reactions at the anode and cathode. The electrolytic cell contains electrodes, typically made of ordinary steel plates. Electrolytic cells are classified as unipolar or bipolar depending on the power connection method. After energization, under the influence of an external electric field, the anode loses electrons and undergoes oxidation, while the cathode gains electrons and undergoes reduction. Wastewater flows through the electrolytic cell, serving as the electrolyte, where oxidation and reduction reactions occur at the anode and cathode respectively, removing harmful substances. In existing technologies, when using electrode plates for catalytic decomposition of wastewater, the core principle is to transfer current to the electrode plates for electrolysis. However, after prolonged use, impurities accumulate on the electrode plates, causing passivation and affecting the current output, resulting in a slower wastewater decomposition rate.

[0003] To address the aforementioned issues, a utility model patent with authorization announcement number CN222312818U discloses a device for preventing passivation of electrode plates in the catalytic treatment of chemical wastewater. This device, through the arrangement of a grinding component, a dust collection hood, a first motor, and a transfer plate, allows for the removal of impurities adhering to the electrode plate surface quickly when the decomposition rate of wastewater slows down after a period of use. The electrode plate is then lifted from the wastewater tank, and the first motor drives the transfer plate to rotate. The transfer plate then moves the grinding component closer to the electrode plate to grind its surface.

[0004] However, in actual use, the electrode plates need to be frequently pulled out of the sewage tank, which is cumbersome and reduces the sewage treatment efficiency, failing to meet the usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide an electrochemical wastewater anti-passivation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An electrochemical wastewater anti-passivation device includes: an electrolysis tank, on the left and right sides of the upper end of the electrolysis tank, a pair of mounting seats for mounting electrode plates are installed, and a scraper is slidably fitted on the electrode plates; a lifting mechanism is installed on the mounting seats for driving the scraper to move up and down; the lifting mechanism includes a pair of lifting racks fixed to the upper end of the scraper, the upper end of the lifting racks passing through the mounting seats, and a lifting component for driving the lifting racks to move is also installed on the upper end of the mounting seats.

[0007] As a preferred embodiment, the lifting assembly includes a pair of lifting frames fixed on the front and rear sides of the upper end of the mounting base. Each lifting frame has a lifting gear rotatably installed inside it. The lifting gear meshes with a corresponding lifting rack. The lifting frame is also equipped with a lifting motor, and the output end of the lifting motor is drivenly connected to the shaft end of the lifting gear.

[0008] As a preferred embodiment, a lifting pulley is also installed on the other end of the lifting gear, and a lifting belt is fitted between the lifting pulleys.

[0009] As a preferred embodiment, the upper end of the lifting rack extends a limiting protrusion on the side near the lifting gear.

[0010] As a preferred embodiment, scraper blades are provided at both the upper and lower ends of the scraper sleeve.

[0011] As a preferred embodiment, a power supply frame is also installed on the upper end of the electrolysis tank, and power supply one and power supply two are installed on the upper end of the power supply frame.

[0012] As a preferred embodiment, the positive terminal of the power supply is electrically connected to the terminal at the top of the left electrode plate via a wire, and the negative terminal of the power supply is electrically connected to the terminal at the top of the right electrode plate via a wire.

[0013] As a preferred embodiment, the positive terminal of the second power supply is electrically connected to the terminal on the upper end of the right electrode plate via a wire, and the negative terminal of the second power supply is electrically connected to the terminal on the upper end of the left electrode plate via a wire.

[0014] Compared with existing technologies, the advantages of this invention are as follows: The lifting motor drives the lifting gears to rotate, and simultaneously, the lifting belt and lifting pulley enable synchronous rotation of the lifting gears on both the front and rear sides. This, in turn, drives the synchronous movement of the lifting racks on both sides, which in turn drives the scraper sleeve to move. Combined with the scraper blades, this cleans the electrode plates and breaks down the passivation layer on their surface, ensuring the efficiency of wastewater electrolysis. This invention has a reasonable structure, allowing for passivation prevention treatment without removing the electrode plates, effectively improving wastewater treatment efficiency and better meeting usage requirements.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Please refer to Figures 1-4 An electrochemical wastewater anti-passivation device includes: an electrolysis tank 1, on the left and right sides of the upper end of the electrolysis tank 1, a pair of mounting seats 11 for mounting electrode plates 15 are installed, and scraper sleeves 16 are slidably fitted on the electrode plates 15; a lifting mechanism 2, mounted on the mounting seats 11, for driving the scraper sleeves 16 to move up and down; the lifting mechanism 2 includes a pair of lifting racks 24 fixed to the upper end of the scraper sleeves 16, the upper ends of the lifting racks 24 penetrating through the mounting seats 11, and a lifting mechanism for driving the lifting racks 24 to move is also installed on the upper end of the mounting seats 11. The lifting assembly includes a pair of lifting frames 21 fixed on the front and rear sides of the upper end of the mounting base 11. Each lifting frame 21 has a lifting gear 22 rotatably installed inside it. The lifting gear 22 meshes with a corresponding lifting rack 24. The lifting frame 21 is also equipped with a lifting motor 23. The output end of the lifting motor 23 is drivenly connected to the shaft end of the lifting gear 22. In this embodiment, a lifting pulley 25 is also installed on the other end of the lifting gear 22. A lifting belt 26 is fitted between the lifting pulleys 25.

[0019] The working principle of this utility model is as follows: In specific use, the lifting motor 23 is started, which drives the lifting gear 22 to rotate. At the same time, the lifting belt 26 and the lifting pulley 25 enable the lifting gear 22 on both the front and rear sides to rotate synchronously, thereby driving the lifting rack 24 on both the front and rear sides to move synchronously, which in turn drives the scraper sleeve 16 to move. With the help of the scraper blade 161, the electrode plate 15 can be cleaned and its passivation layer can be destroyed to ensure the efficiency of electrolytic wastewater treatment. The lifting motor 23 drives the lifting gear 22 to rotate in the forward direction, which drives the lifting rack 24 to move upward. The lifting motor 23 drives the lifting gear 22 to rotate in the reverse direction, which drives the lifting rack 24 to move downward.

[0020] As a further solution, a limiting protrusion 241 extends from the upper end of the lifting rack 24 near the lifting gear 22. By providing the limiting protrusion 241, the lifting rack 24 can be effectively prevented from falling off.

[0021] To improve the cleaning effect, scraper blades 161 are provided at both the upper and lower ends of the scraper sleeve 16. By providing scraper blades 161, it is convenient to clean the electrode plate 15.

[0022] As a further embodiment, a power supply frame 12 is also installed on the upper end of the electrolysis tank 1. Power supply 13 and power supply 2 14 are installed on the upper end of the power supply frame 12. The positive terminal of power supply 13 is electrically connected to the terminal 151 on the upper end of the left electrode plate 15 through a wire, and the negative terminal of power supply 13 is electrically connected to the terminal 151 on the upper end of the right electrode plate 15 through a wire. The positive terminal of power supply 2 14 is electrically connected to the terminal 151 on the upper end of the right electrode plate 15 through a wire, and the negative terminal of power supply 2 14 is electrically connected to the terminal 151 on the upper end of the left electrode plate 15 through a wire.

[0023] Taking the left electrode plate 15 as an example, when power supply 13 is on, an oxidation reaction occurs on the left electrode plate 15, which easily forms a passivation layer, affecting the efficiency of electrolytic wastewater treatment. When it is necessary to clean the passivation layer, power supply 13 stops supplying power, and power supply 2 14 is supplied. The left electrode plate 15 undergoes a reduction reaction, which can destroy the passivation layer on the surface, effectively preventing the passivation of the electrode plate 15, ensuring the efficiency of electrolytic wastewater treatment, and better meeting the usage requirements.
