[0025] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.
[0026] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
[0027] Fluoride salt is needed in electrolysis production, so workers are required to add fluoride salt to the fluoride salt box. However, during the transportation of bagged fluoride salt and the workers adding fluoride salt to the fluoride salt box, foreign objects may be mixed in, which will affect the operation of the feeder and cause the feeder to leak due to poor sealing due to foreign objects. This will not only cause a waste of fluoride salt materials, but also affect the safe operation of the electrolytic cell.
[0028] The embodiment of the present application provides a feeding and filtering device for an electrolytic cell, which can avoid the waste of fluoride salts to a certain extent and enable the electrolytic cell to operate normally.
[0029] See also Figure 1 , Figure 1 A schematic diagram of the partial structure of the feeding and filtering device for an electrolytic cell provided in an embodiment of the present application. As shown in the figure, the present embodiment provides a feeding and filtering device for an electrolytic cell, comprising two material boxes 1, which are arranged and connected in the up-down direction, and the top of the material box 1 located above is formed as a feeding port 11, through which fluoride salt can be added to the material box 1; and in order to avoid the feeder from being poorly sealed due to the obstruction of foreign matter, the feeding and filtering device for an electrolytic cell provided in the present embodiment also includes a filter element 2, which is arranged between the two material boxes 1 and is detachably connected to at least one of the two material boxes 1 through a fastener. Among them, the fastener can be a threaded fastener such as a screw.
[0030] In this way, by arranging the filter element 2 between the two material boxes 1, when adding fluoride salt through the feeding port 11, the phenomenon of poor sealing of the feeder due to obstruction by foreign matter can be avoided to a certain extent.
[0031] Please combine Figure 2 and Figure 3 , Figure 2 for Figure 1 A cross-sectional view of Figure 3 for Figure 2 A schematic diagram of the enlarged local structure at A in the middle. In some optional embodiments, the filter element 2 includes an annular connection portion 21 and a first filter screen 22, and the annular connection portion 21 is detachably connected to the material box 1 through a fastener; the first filter screen 22 is connected to the inner peripheral wall of the annular connection portion 21 and extends toward the material box 1 connected to the annular connection portion 21. In this way, by providing the filter element 2 including the annular connection portion 21 and the first filter screen 22, not only can the connection with the material box 1 be achieved, but also a certain filtering effect can be achieved on the fluoride salt added to the material box 1.
[0032] Due to the limitation of the material of the first filter 22 itself, the shape of the first filter 22 is difficult to be fixed in the direction away from the annular connection portion 21, so the diameter of the first filter 22 gradually decreases in the direction away from the annular connection portion 21. It can also be understood that the size of the first filter 22 gradually decreases in the direction away from the annular connection portion 21.
[0033] It is not difficult to understand that the filtering effect of the first filter 22 can generally be improved by limiting the diameter of the mesh of the first filter 22. Therefore, in the specific implementation of this embodiment, in order to make the first filter 22 have a better filtering effect, the mesh diameter of the first filter 22 is 6 mm.
[0034] It should be noted that, in other embodiments, the mesh diameter of the first filter 22 can be selected according to the actual cleanliness of the fluoride salt added to the material box 1. Here, the mesh diameter of the first filter 22 is not specifically limited.
[0035] Furthermore, in some embodiments, when installing the filter element 2, in order to improve the installation efficiency between the filter element 2 and the material box 1, the relative position between the filter element 2 and the material box 1 can be determined first, and then the filter element 2 and the material box 1 can be connected.
[0036] Therefore, as an optional embodiment, the outer edge of the annular connecting portion 21 is formed with a flange 211 extending in the up-down direction, and the flange 211 is located outside the material box 1 to limit the relative position of the filter element 2 and the material box 1 in the radial direction of the material box 1. In this way, through the setting of the flange 211, when the filter element 2 is installed, the filter element 2 and the material box 1 can be aligned first, and then the filter element 2 and the material box 1 can be connected.
[0037] Specifically, the annular connecting portion 21 further includes an annular plate 212 connected to the first filter screen 22 . The annular plate 212 is sandwiched between the two material boxes 1 . The flange 211 is connected to the material box 1 via fasteners, such as screws.
[0038] Please combine Figure 4, Figure 4 This is a cross-sectional view of another partial structure of the feed filter device for an electrolytic cell provided in an embodiment of the present application. As shown in the figure, a filter cavity 221 is formed in the first filter screen 22, and a second filter screen 23 is arranged in the filter cavity 221; the mesh diameter of the second filter screen 23 is larger than the mesh diameter of the first filter screen 22. In this way, the second filter screen 23 can play a certain initial filtering role, so that the filter element 2 can have a two-layer filtering effect, further improving the filtering effect of the filter element 2.
[0039] In order to set the second filter screen 23, in some embodiments, the second filter screen 23 is a sheet structure. In this way, it is not only convenient to process and shape the second filter screen 23, but also convenient to connect the second filter screen 23 with the first filter screen 22.
[0040] Furthermore, in order to improve the filtering effect of the filter element 2, a plurality of second filter screens 23 are arranged in the filter cavity 221 at intervals in the vertical direction; and in the downward direction, the mesh diameter of the second filter screen 23 gradually decreases. It is not difficult to understand that the process of adding fluoride salt into the material box is a process from top to bottom, so the closer to the bottom, the smaller the impurities filtered in the fluoride salt will be. In this way, if these impurities need to be filtered out, the mesh diameter of the second filter screen 23 needs to be reduced, so that the filtering effect of the filter element 2 will be improved.
[0041] When the filter element 2 includes the second filter screen 23, the first filter screen 22 can be bonded to the annular connection portion 21, and the second filter screen 23 can be bonded to the first filter screen 22. In this way, the first filter screen 22 and the second filter screen 23 are connected, and the first filter screen 22 and the annular connection portion 21 are connected.
[0042] It should be noted that the annular connecting portion 21 may be made of metal. The material of the annular connecting portion 21 is not limited.
[0043] Please combine Figure 5 and Figure 6 , Figure 5 A cross-sectional view of another partial structure of the feeding and filtering device for an electrolytic cell provided in an embodiment of the present application, Figure 6 for Figure 5 The enlarged schematic diagram of the local structure at B in the middle. In order to allow the fluoride salt to be filtered for a long time during the addition process, so as to remove the impurities inside the fluoride salt to a greater extent, in some optional embodiments, there can be two filter elements 2, one filter element 2 corresponding to one material box 1; the two filter elements 2 are detachably connected by fasteners. In this way, the fluoride salt can be filtered for a longer time during the falling process, further improving the purity of the fluoride salt.
[0044] Specifically, the annular plates 212 of the two filter elements 2 are sandwiched between the two material boxes 1, and the flanges 211 are connected to the corresponding material boxes 1 through fasteners.
[0045] It should be noted that the first filter screen 22 in the upper filter element 2 is a sheet-like structure, and the first filter screen in the lower filter element 2 can still form a filter cavity 221 , and a second filter screen 23 can be disposed in the filter cavity 221 .
