[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] Example 1: Reference Figure 1-Figure 16 , an electrolytic cell liquid level regulating device, comprising: an electrolytic cell box body 1 and an observation window 2 arranged on the electrolytic cell box body 1, a float barrel 3 is arranged inside the electrolytic cell box body 1, a side of the observation window 2 located inside the electrolytic cell box body 1 is attached with a corresponding scraper 4, and also includes: a processing element 5 for driving the scraper 4 to scrape along the inner surface of the observation window 2; wherein the processing element 5 includes a slide plate 51 fixedly connected to the inner wall of the electrolytic cell box body 1, and a pulling member 52 between the float barrel 3 and the scraper 4 is arranged on the slide plate 51.

[0023] In the present invention, as the inside of the electrolytic cell box 1 operates, when the electrode material is gradually consumed, some fine particulate matter is generated and escapes to the observation window 2 on the electrolytic cell box 1, causing the observation window 2 to be blurred. The electrolyte height inside the electrolytic cell box 1 is reduced, causing the float 3 to automatically move downward. The float 3 will pull the pulling member 52 downward at the same time. The pulling member 52 pulls the scraper 4 to scrape off the particulate matter and impurities such as the electrolyte on the observation window 2. There is no need for manual entry into the electrolytic cell box 1 to clean the observation window 2, which helps observers to promptly and clearly view the situation inside the electrolytic cell box 1 from the outside.

[0024] Example 2: Reference Figure 1-Figure 16 , which is basically the same as the first embodiment, further, the pulling member 52 includes a first slider 521 slidably connected to the slide plate 51, and a connecting plate 522 is fixedly connected to the first slider 521, and one end of the connecting plate 522 away from the first slider 521 is fixed to the float 3.

[0025] A pulling block 523 is fixedly connected to the first sliding block 521, a mounting ear 524 is fixedly connected to the top of the scraper 4, a pull rope 525 is fixedly connected between the mounting ear 524 and the pulling block 523, and a guide wheel 526 for guiding the pull rope 525 is fixedly installed on the inner wall of the electrolytic cell box 1 close to the slide plate 51.

[0026] A limit member 53 for pulling the scraper 4 is provided between the slide plate 51 and the scraper 4. The limit member 53 includes a first guide rod 531 fixedly connected to the lower part of the scraper 4. The first guide rod 531 passes through the slide plate 51 and is slidably connected to the slide plate 51. A tension spring 532 is sleeved on the first guide rod 531. One end of the tension spring 532 is fixedly connected to the first guide rod 531, and the other end of the tension spring 532 is fixedly connected to the slide plate 51.

[0027] In the present invention, the float 3 automatically moves downward, and the float 3 drives the first slider 521 to move downward through the connecting plate 522. When the first slider 521 moves downward, it will drive the pulling block 523 downward together. The pulling block 523 pulls the pull rope 525 downward. The pull rope 525 is guided by the guide wheel 526 to pull the mounting ear 524, thereby pulling the scraper 4 to slide. The scraper 4 slides horizontally under the guidance of the first guide rod 531 to scrape off the electrolyte and particulate matter attached to the observation window 2; when the scraper 4 drives the first guide rod 531 to slide, the tension spring 532 will be stretched, and the tension spring 532 facilitates the automatic resetting of the scraper 4.

[0028] Example 3: Reference Figure 1-Figure 15, which is basically the same as the first embodiment, and further, a supply tank 6 is fixedly connected to the left side of the electrolytic cell housing 1, and a liquid level adjustment component 61 which is interconnected with the float 3 is arranged between the supply tank 6 and the electrolytic cell housing 1, and the liquid level adjustment component 61 includes a first L-shaped plate 611 fixedly connected to the first slider 521, and a first rack 612 is fixedly connected to the end of the first L-shaped plate 611 away from the first slider 521, and a rotating rod 613 is rotatably connected to the supply tank 6.

[0029] A first gear 614 meshing with the first rack 612 is fixedly connected to the rotating rod 613, a circular plate 615 is fixedly connected to the end of the rotating rod 613 away from the first gear 614, a toggle rod 616 is eccentrically fixedly connected to the circular plate 615, a mounting plate 617 is fixedly connected to the inner wall of the supply tank 6, a water pump 618 is fixedly installed on the mounting plate 617, and a switch assembly 62 for turning on and off the water pump 618 is fixedly connected to the top of the water pump 618.

[0030] The switch assembly 62 includes a fixed cylinder 621, the interior of the fixed cylinder 621 is slidably connected to a sliding rod 622, the top of the sliding rod 622 is fixedly connected to a first pressing plate 623, a second pressing plate 624 is hinged on the first pressing plate 623, a first torsion spring 625 is fixedly connected to the bottom of the first pressing plate 623, one end of the first torsion spring 625 away from the first pressing plate 623 is fixedly connected to the second pressing plate 624, a water suction pipe 619 is fixedly connected between the water pump 618 and the supply tank 6, a water outlet pipe 620 is fixedly connected between the water pump 618 and the electrolytic cell box 1, and a water spray hole 6201 is opened around the surface of the water outlet pipe 620 near the bottom of the electrolytic cell box 1.

[0031] In the present invention, when the water inside the electrolytic cell box 1 decreases, the float 3 will automatically move downward. When the float 3 moves downward, it will drive the first slider 521 downward through the connecting plate 522. When the first slider 521 moves downward, it will drive the first rack 612 to move downward, meshing with the first gear 614 to rotate the first gear 614. When the first gear 614 rotates, it will drive the rotating rod 613 and the circular plate 615 to rotate, thereby driving the toggle rod 616 on the circular plate 615 to rotate eccentrically to press the second pressing plate 624. The second pressing plate 624 drives the first pressing plate 623 is pressed, thereby driving the sliding rod 622 to slide inside the fixed cylinder 621, so that the water pump 618 is turned on, so that water is sucked from the supply tank 6 through the water suction pipe 619, and enters the electrolytic cell box 1 through the water outlet pipe 620 for automatic replenishment, so that it can be automatically replenished when the liquid inside the electrolytic cell box 1 is reduced. At the same time, the water in the water outlet pipe 620 is sprayed out from the water spray hole 6201 to spray water around the inside of the electrolytic cell box 1 to supply liquid, which helps to enhance the fluidity of the liquid inside the electrolytic cell box 1 and make the electrolytic cell more efficient during operation; When the sliding rod 622 slides to the bottom of the fixed cylinder 621, the circular plate 615 may continue to drive the toggle rod 616 to rotate and squeeze the second pressing plate 624. At this time, the second pressing plate 624 can rotate by squeezing the first torsion spring 625 at the bottom, so that the toggle rod 616 can be separated from the second pressing plate 624. When the liquid level inside the electrolytic cell box 1 is slowly restored, the float bucket 3 will automatically move upward, thereby making the first rack 612 move upward, making the first gear 614 rotate in the opposite direction, and making the toggle rod 616 rotate in the opposite direction to push the bottom of the second pressing plate 624 upward, so that the sliding rod 622 is pulled upward to turn off the water pump 618. It should be noted that the sliding relationship between the sliding rod 622 and the fixed cylinder 621 is equivalent to a telescopic rod, which can be limited by friction. The water pump 618 is electrically connected to the fixed cylinder 621 and the sliding rod 622. When the sliding rod 622 is upward, the water pump 618 is automatically turned off, and when the sliding rod 622 is downward, the water pump 618 will be turned off.

[0032] Example 4: Reference Figure 2-Figure 16 , which is basically the same as the first embodiment, and further, a second slider 7 is slidably connected inside the slide plate 51, a stirring member 71 is arranged between the second slider 7 and the electrolytic cell box body 1, the stirring member 71 includes a stirring rod 711 rotatably connected inside the electrolytic cell box body 1, and a plurality of extension rods 712 are fixedly connected to the stirring rod 711, a driving member 72 for driving the stirring member 71 to rotate is arranged between the second slider 7 and the stirring member 71, the driving member 72 includes a second L-shaped plate 721 fixedly connected to the second slider 7, a driving plate 722 is hinged at one end of the second L-shaped plate 721 away from the second slider 7, a second torsion spring 723 is arranged between the upper and lower sides of the driving plate 722 and the second L-shaped plate 721, and a push rod 729 is fixedly connected between the first slider 521 and the second slider 7.

[0033] A slide rail 724 is fixedly connected to the inner wall of the electrolytic cell box 1, and a second guide rod 725 is slidably connected inside the slide rail 724. The second guide rod 725 is fixedly connected to the end away from the slide rail 724 with a second rack 726, and a paddle 727 is fixedly connected to the second rack 726. A second gear 728 meshing with the second rack 726 is fixedly connected to the stirring rod 711.

[0034] In the present invention, when the liquid level inside the electrolytic cell housing 1 drops to the lowest, the float 3 will drive the first slider 521 downward, and the first slider 521 will push the push rod 729 to push the second slider 7 downward, and then the second slider 7 will drive the second L-shaped plate 721 downward, and at the same time drive the driving plate 722 downward to compress the second torsion spring 723 to rotate and disengage from the paddle plate 727 on the second rack 726. When the liquid level inside the electrolytic cell housing 1 gradually rises, the float 3 will drive the first slider 521 upward, and then the second slider 7 upward, so that the driving plate 722 moves upward through the collision with the paddle plate 727 to make the second rack 726 move upward and mesh with the second gear 728 to rotate the second gear 728, and at the same time drive the stirring rod 711 and the extension rod 712 to rotate, so as to stir the liquid inside the electrolytic cell housing 1, which can help accelerate the diffusion of ions in the electrolytic cell housing 1, and make the internal liquid concentration distribution more uniform. At the same time, it can also prevent the heat generated during the electrolysis process from being concentrated in one part to cause damage to the electrode material. It should be noted that the second torsion spring 723 can make the driving plate 722 rotate up and down. The second torsion spring 723 is not fixed to the driving plate 722, but is only fixed to the second L-shaped plate 721, which helps to automatically disengage the driving plate 722 from the shift plate 727 when the driving plate 722 moves downward, and will not cause the second rack 726 to move downward; the second guide rod 725 can guide the second rack 726 when it slides up and down.

[0035] Embodiment 5: The present invention also provides a method for adjusting the liquid level of an electrolytic cell, which is performed by the following steps: S1. When the electrolytic cell box 1 is running, some fine particulate matter may be generated as the electrode material is gradually consumed. These particulate matter may be suspended in the electrolyte or escape to the observation window 2 on the electrolytic cell box 1, causing the observation window 2 to be unclear. The electrolyte level inside the electrolytic cell box 1 is reduced, so that the float 3 automatically moves downward, and the float 3 drives the first slider 521 to move downward through the connecting plate 522; S2. When the first slider 521 moves downward, it will drive the pulling block 523 downward. The pulling block 523 pulls the pull rope 525 downward. The pull rope 525 is guided by the guide wheel 526 to pull the mounting ear 524, thereby pulling the scraper 4 to slide. The scraper 4 slides horizontally under the guidance of the first guide rod 531 to scrape off the electrolyte and particulate matter attached to the observation window 2.
