[0030] The adjusting support device 2 includes a supporting rail 21, which is located on the supporting seat 13 and is specifically connected by welding or gluing. A groove is provided on the upper surface of the supporting rail 21, and a first supporting bevel block 22 and a second supporting bevel block 23 are placed in the groove of the supporting rail 21.

[0033] Example 3

[0034] like Figure 4 As shown, a flexible support structure containing an electrolytic cell device is arranged along the circumference of the electrolytic cell 5 , and the flexible support structure containing the electrolytic cell device is located between two electrolytic cell connecting bolts 6 to support the electrolytic cell 5 .

[0035] The flexible support structure of the utility model includes an electrolytic cell device, and its working principle is as follows: the flexible support structure including the electrolytic cell device selects one or two groups of flexible support devices to effectively support the electrolytic cell according to the arrangement of the electrolytic cell connection bolts. First, the adjustment support device is welded or glued on the top of the transfer trolley, and the connection between the first support bevel block and the second support bevel block in the adjustment support device is realized through the second connection component, and then the assembled device is placed as a whole at the bottom of the electrolytic cell. The device can enable the transfer trolley to realize the rapid and convenient movement of the entire support device along the axial direction at the bottom of the electrolytic cell.

[0036] Secondly, according to the actual distance from the bottom of the electrolytic cell to the ground, the blind holes above the first and second support oblique columns in the support device are adjusted by rotating the external force rod to achieve the screwing length of the two adjustment support oblique blocks and the corresponding inner and outer threads of the two support oblique columns, so that the support device can be quickly adjusted along the radial direction of the electrolytic cell. During the adjustment process, it is necessary to ensure that each insulating plate is tangent to the outer diameter of the electrolytic cell. The insulating device is made of insulating material and is placed at the bottom of the electrolytic cell close to the electrolytic cell body, which can effectively avoid conductivity and ensure that the flexible support structure effectively supports the electrolytic cell without interfering with the electrolytic cell connection bolts. When each insulating plate is tangent to the outer diameter of the electrolytic cell, there is no need to further adjust the screwing position of the nut of the connecting assembly; when each insulating plate is not tangent to the outer diameter of the electrolytic cell, the screwing position of the nut of the connecting assembly can be adjusted to achieve the relative approach or distance of the two support oblique blocks along the groove on the upper surface of the support slide rail, so as to achieve fine adjustment of the support device along the radial direction of the electrolytic cell, and finally ensure that each insulating plate is tangent to the outer diameter of the electrolytic cell. Ensure that the supporting device effectively supports the electrolytic cell.

[0037] Finally, the electrolytic cell needs to work continuously under high-temperature conditions with pressure. As the use time increases, the electrolytic cell may sink due to the reduced performance of the electrolytic cell sealing gasket. If the sunken part is not effectively supported in time, the electrolytic cell will leak alkali or short-circuit. The utility model includes a flexible support structure for the electrolytic cell device, which can form an effective support for the part of the electrolytic cell that may sink. As the use time of the electrolytic cell increases, the screwing position of the nut in the connecting assembly can be further adjusted to continuously ensure that the support structure is effective, thereby reducing the probability of alkali leakage or short-circuit of the electrolytic cell due to sinking and deformation, thereby extending the service life of the electrolytic cell. The utility model includes a flexible support structure for the electrolytic cell device, which can adjust the screwing position of the nut in the connecting assembly, which is easy to operate and convenient for maintenance of the electrolytic cell during use.
