Detailed implementation manners

[0030] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Embodiment 1:

[0032] In this embodiment, as Figures 1-9As shown in the figure, an electrolytic cell with an auxiliary support function includes an electrolytic cell body 101, which is a common electrolytic cell structure in this field. A base 102 is provided below the electrolytic cell body 101 to play a supporting role. End plates 103 are provided at both ends of the electrolytic cell body 101. A number of tension members are evenly arranged outside the electrolytic cell body 101. The number of tension members is used to press the two end plates 103 onto the electrolytic cell body 101. The end plates 103 are connected to the base 102 through a connection assembly. It also includes a first support mechanism 200 and a second support mechanism 300. The first support mechanism 200 is arranged at the lower end of the electrolytic cell body 101 to prevent the middle section of the electrolytic cell body 101 from sagging. The second support mechanism 300 is arranged on both sides of the first support mechanism 200 to increase the structural stability. Before the electrolytic cell with an auxiliary support function starts to be used, first check whether the electrolytic cell can be used normally, and then install the first support mechanism 200 and the second support mechanism 300 so that the electrolytic cell enters the state of waiting to be used;

[0033] The tension members include a symmetrically arranged first tension rod 104 and a second tension rod 105. The axial direction of the tension members is parallel to the axial direction of the electrolytic cell body 101, and adjacent tension members are parallel to each other. One end of the first tension rod 104 and the second tension rod 105 are both connected to the end plate 103, and the other ends of the first tension rod 104 and the second tension rod 105 both extend into the elastic end 106. The tension members have the ability to adapt to thermal deformation laterally, so that the tension members have the ability to adjust in the horizontal direction.

[0034] Among them, as Figure 3 shown, the connection assembly includes a roller 107. The roller 107 is rotatably arranged inside the connecting plate 108. Convex blocks 109 are symmetrically arranged at the top of the connecting plate 108 to facilitate the positioning of the end plate 103. The end plate 103 is arranged at the upper end of the connecting plate 108 and is slidably connected to the convex block 109. The end plate 103 is fixedly connected to the connecting plate 108 through bolts to facilitate the positioning of the end plate 103. Through the roller 107, the stress generated by the thermal expansion of the electrolytic cell is dispersed.

[0035] Among them, as Figures 5-9As shown in the figure, the first support mechanism 200 includes a support base 201 fixedly arranged at the upper end of the base 102. A first wedge block 202 is fixedly connected to the upper end of the support base 201. A second wedge block 203 is arranged above the first wedge block 202. Chute grooves 204 are formed on the opposite sides of the first wedge block 202 and the second wedge block 203. Trapezoidal blocks 205 are slidably arranged inside the chute grooves 204. Threaded holes are formed on the surfaces of the trapezoidal blocks 205. A bidirectional lead screw 206 is threadedly connected inside the threaded holes. When the staff rotates the bidirectional lead screw 206, the two trapezoidal blocks 205 can be driven to move relatively or away from each other, so as to adjust the height of the support wheels 208 according to the specification size of the electrolytic cell body 101, which has good adaptability and can support the electrolytic cell body 101. One end of the bidirectional lead screw 206 extends to the outside of the trapezoidal block 205 and is connected with a nut. A bracket is fixedly arranged at the upper end of the second wedge block 203. Bases 207 are symmetrically arranged at the upper end of the bracket. Support wheels 208 are arranged at the tops of the bases 207. The support wheels 208 are in contact with the electrolytic cell body 101. After the electrolytic cell body 101 sinks slightly due to reaction and gravity, it will contact the support wheels 208, so as to support the electrolytic cell body 101.

[0036] Among them, as Figures 4-8 shown in the figure, the second support mechanism 300 includes a support rod 301 located below the electrolytic cell body 101 and used to support the electrolytic cell body 101. After the electrolytic cell body 101 sinks slightly due to reaction and gravity, it will contact the support rod 301, so as to support the electrolytic cell body 101. The support rod 301 is in contact with the electrolytic cell body 101. Both ends of the support rod 301 extend along the axial direction of the electrolytic cell body 101 and are connected with the end plates 103. A support part 302 for supporting the support rod 301 is arranged at the lower end of the support rod 301. The support part 302 is fixedly connected with the base 102. A small gap exists between the support rod 301 and the surface of the electrolytic cell body 101, so that when installing the support rod 301, the electrolytic cell body 101 can be prevented from being worn by the support rod 301, which is convenient for installation and increases the stability of the structure.

[0037] Among them, as Figure 3 shown in the figure, a slide rail 110 is fixedly installed on the upper surface of the base 102. The specifications and dimensions of the slide rail 110 are adapted to those of the rollers 107, so that the slide rail 110 abuts against the rollers 107. During the rolling of the rollers 107 on the slide rail 110, the stress generated by the thermal expansion of the electrolytic cell can be released, reducing the wear on the electrolytic cell.

[0038] Among them, as Figure 3As shown, several U-shaped blocks 111 are slidably arranged at the upper end of the slide rail 110. The U-shaped blocks 111 are symmetrically arranged on both sides of the connecting plate 108 to limit the movement range of the roller 107 and prevent the large movement distance of the roller 107 from affecting the electrolysis work. The U-shaped blocks 111 are fixedly connected to the base 102 by several screws. Several round holes are provided on the surface of the base 102 to facilitate adjusting the position of the U-shaped blocks 111 according to the size of the electrolytic cell body 101, which is convenient for disassembly and installation.

[0039] Embodiment 2:

[0040] The difference from Embodiment 1 is that as Figure 5 shown, insulating sleeves are arranged on the outer peripheries of the support rod 301 and the support wheel 208. The insulating sleeves are made of insulating materials and have the effect of preventing electric leakage, which is convenient for achieving the insulation purpose.

[0041] Among them, as Figure 1 shown, the number of the support parts 302 is several. The support parts 302 are arranged at intervals along the axial direction of the electrolytic cell body 101 to increase the support stability.

[0042] During use, the staff rotates the bidirectional lead screw 206, which can drive the two trapezoidal blocks 205 to move relatively or away from each other, so as to adjust the height of the support wheel 208 according to the specification size of the electrolytic cell body 101. After the electrolytic cell body 101 sinks slightly due to reaction and gravity, it will contact the support wheel 208, so as to support the electrolytic cell body 101. Moreover, support rods 301 are arranged on both sides of the electrolytic cell body 101, so that the electrolytic cell body 101 will contact the support rods 301, increasing the support effect on the electrolytic cell body 101, thereby reducing the sinking probability of the electrolytic cell body 101 and reducing the possibility of safety accidents.

[0043] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
