In severe cases, it may cause abnormal cell conditions such as voltage fluctuations, reducing the current efficiency of the electrolytic cell. In the past, it was difficult and incomplete to use an overhead crane grab to grab the sediment when replacing the anode. Manual cleaning without suitable special tools is time-consuming and labor-intensive, and working in extremely high-temperature areas for a long time poses a safety hazard. Summary of the Invention

[0013] The following will be combined with the drawings in the embodiment of the present invention to clearly and completely describe the technical solutions in the embodiment of the present invention. Obviously, the embodiment described is only a part of the embodiment of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is Figure 2 Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0014] See also Figure 1-2 The utility model provides a technical solution: a special tool for cleaning sediment at the bottom of an electrolytic cell, comprising a salvaging part 1, a rod 2 and an angle iron 3;

[0015] The salvage part 1 includes a connecting plate 11, a bent plate 12 and a scraper 13. One end of the connecting plate 11 is connected to the rod 2 through an angle iron 3, and the other end of the connecting plate 11 is integrally connected to the bent plate 12. One end of the bent plate 12 is integrally connected to the scraper 13. An obtuse angle is formed between the scraper 13 and the bent plate 12. When cleaning the sediment at the bottom of the tank, the sediment is scraped up by the scraper 13. When scooping up, the sediment is gathered and scooped up by the angle between the scraper 13 and the bent plate 12, which is convenient for workers to operate.

[0016] Furthermore, in order to prevent the electrolyte from being fished out and wasted when salvaging the sediment, a plurality of hollow grids 14 are evenly distributed on the scraper 13 and the bent plate 12 , so that the electrolyte flows out from the hollow grids 14 .

[0017] Furthermore, the rod portion 2 includes a connecting rod 21 and an adjusting rod 22. The connecting rod 21 is connected to the connecting plate 11. An external thread is provided on the outer side surface of one end of the connecting rod 21, and an internal thread is provided on the inner side surface of the adjusting rod 22. The adjusting rod 22 is threadedly connected to the connecting rod 21. Through the threaded connection between the adjusting rod 22 and the connecting rod 21, the operating space of the workers can be adjusted according to the spacing of the electrolytic cells, making it convenient for the workers to clean.

[0018] Furthermore, in order to improve the connection strength between the rod portion 2 and the connecting plate 11 , the angle iron 3 is connected to the connecting plate 11 and the rod portion 2 by welding.

[0019] Furthermore, in order to effectively prevent the interference of the magnetic field around the electrolytic cell and the strong attraction to the tool, the rod 2 and the salvage part 1 are both made of stainless steel.

[0020] During use: workers adjust the depth of the adjusting rod 22 screwed into the connecting rod 21, thereby adjusting the length of the entire rod 2, which is convenient for workers to operate. When salvaging the sediment at the bottom of the tank, the scraper 13 fits with the bottom of the tank and scrapes the sediment to the edge of the electrolytic cell. When lifting the sediment, the sediment gathers at the position of the bent plate 12, and the electrolyte flows out of the hollow grid 14, and finally the sediment is salvaged.

[0021] The utility model can clean the sediment at the bottom of the electrolytic cell. After trial, the tool is easy to operate and easy to make, and can effectively eliminate the influence of the magnetic field and eliminate hidden dangers of work safety, thus creating a safer and more reliable working environment for workers.
