[0025] The embodiments of the utility model are further described in detail below with reference to the accompanying drawings, so that the purpose, technical solution and technical effect of the utility model can be more clearly presented.

[0026] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] like Figure 1-4 As shown, this utility model discloses a sealing tool for an anode guide rod of an electrolytic cell, including a base 1, a pressure applying component 2, an insulating block assembly 5, and a sealing ring. The sealing ring is located on the edge of the electrolytic cell and is secured to the anode guide rod 7. The insulating block assembly 5 is fitted around the sealing ring. Pressure is applied by the pressure applying component 2, causing the insulating block assembly 5 to tightly adhere the sealing ring to the anode guide rod 7, thus achieving a seal on the edge of the electrolytic cell for the anode guide rod 7. Figure 4 As shown.

[0028] The base 1 is fixed to the electrolytic cell and located on one side of the sealing ring, serving as the force support for the entire sealing tool. Specifically, the base 1 is welded to the electrolytic cell and aligned with the sealing ring. The insulating block assembly 5 is a U-shaped frame that is correspondingly fitted onto the outside of the sealing ring. The insulating block assembly 5 includes a first insulating block 51, a second insulating block 52, and fasteners 3. There are two second insulating blocks 52, symmetrically arranged on both sides of the first insulating block 51 and capable of moving axially along the first insulating block 51. The first insulating block 51 and the second insulating block 52 are fixed together by the fasteners 3. The pressure-applying component 2 is an elastic element located between the base 1 and the insulating block assembly 5, providing spring force to press the insulating block assembly 5 against the sealing ring.

[0029] The above scheme uses base 1 to fix the sealing tool to the electrolytic cell, and installs the sealing ring between the electrolytic cell brow and the anode guide rod 7 to form a preliminary seal. An insulating block assembly 5, in the form of a U-shaped frame, is fitted over the sealing ring. It consists of a first insulating block 51, a second insulating block 52 that can move axially along the first insulating block 51, and fasteners 3. Its size can be adjusted and fixed according to the actual situation of the anode guide rod 7. The pressure application assembly 2, using an elastic element, is installed between base 1 and insulating block assembly 5. The spring force generated by the deformation of the elastic element pushes the insulating block assembly 5 to continuously press the sealing ring, forming a tight sealing structure. Simultaneously, the insulating block assembly 5 provides insulation, preventing current leakage.

[0030] like Figure 1 As shown, the pressure application component 2 is a long strip-shaped spring, and the springs are arranged in two parallel sets. The two sets of parallel springs can provide more stable and uniform pressure. Even if one set of springs experiences a minor failure or performance degradation, the other set can still maintain a certain sealing pressure to ensure the sealing effect. Of course, the pressure application component 2 can be a cantilever beam elastic structure or a pneumatic elastic structure, etc., to provide pressure to the insulating block assembly 5.

[0031] Here is as Figure 1 and Figure 2 As shown, in the insulating block assembly 5, the first insulating block 51 has a sliding groove on its side, which is arranged along the axial direction of the first insulating block 51. One end of the second insulating block 52 is correspondingly slidably fitted in the sliding groove. A long, narrow hole is provided in the sliding groove of the first insulating block 51, penetrating the first insulating block 51. A fastener 3 passes through the long, narrow hole and connects to the second insulating block 52. The fastener 3 is a knob bolt, with the knob end located away from the second insulating block 52, and the bolt end passing through the long, narrow hole and threadedly connected to the second insulating block 52. The fastener 3 can also directly use existing fastening structures such as bolt structures or quick-release fastening structures to achieve fastening of the two second insulating blocks 52 after adjusting the width of the corresponding anode guide rod 7. To improve the high-temperature resistance and corrosion resistance of the insulating block assembly 5, the outer layer of the insulating block assembly 5 is wrapped with an aluminosilicate nanolayer. The U-shaped opening of the insulating block assembly 5 is provided with a sealing movable insulating block 6, which is connected to the second insulating block 52. The sealing movable insulating block 6 can be provided with a slot, and the second insulating block 52 can be provided with a corresponding slot to form a corresponding crimp. Other methods can also be used to achieve the connection, such as clamp connection.

[0032] Here, a connecting plate is provided on the base 1 for connecting to the pressure application component 2. A snap-fit ​​plate 4 is provided on the side of the base 1 near the sealing ring. The snap-fit ​​plates 4 are symmetrically arranged and located on both sides of the pressure application component 2. The snap-fit ​​plates 4 are used to lock the insulating block assembly 5 when replacing the anode guide rod 7, so as to prevent the insulating block assembly 5 from interfering with the replacement and installation of the anode guide rod 7.

[0033] The specific operating steps of the above scheme are as follows: First, pre-weld the base 1 onto the electrolytic cell, so that the base 1 is located on one side of the sealing ring; then place the sealing ring on the edge of the electrolytic cell and accurately clamp it onto the anode guide rod 7; next, slide the second insulating block 52 of the insulating block assembly 5 along the groove of the first insulating block 51, adjust the spacing according to the position of the guide rod, and thread the knob bolt through the elongated hole of the first insulating block 51 to the second insulating block 52, fix it into a U-shaped frame, and clamp it onto the outside of the sealing ring; then connect one end of the pressure application component 2 to the connecting plate of the base 1, and the other end abuts against the insulating block assembly 5, using the elastic force of the spring to press the insulating block assembly 5 to the sealing ring; finally, install the sealing movable insulating block 6 at the U-shaped opening of the insulating block assembly 5, connect it to the second insulating block 52, and complete the installation of the entire sealing tool.

[0034] This invention effectively prevents electrolyte and harmful fumes from leaking from the gap between the electrolytic cell rim and the anode rod, reducing environmental pollution and protecting the health of operators. The entire design is simple in structure and easy to install, reducing installation and maintenance time and costs, and contributing to improved continuity and economy in electrolytic production.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of the patent application of this utility model. All equivalent changes, substitutions, or modifications made within the technical spirit and principles indicated by this utility model should be included within the scope of patent protection covered by this utility model.
