Problems solved by technology

[0003] The present invention solves the problem that the wheel clamper applies too much pressure to the aluminum frame, easily damages the anode, and adding conductive fillers between the anode guide rod and the aluminum frame or at the lower end of the anode guide rod will increase the workload and operating costs. The problem is to provide a clamping and tightening device for aluminum electrolytic cells, so as to realize the reliable and stable clamping of the anode under the premise of ensuring the integrity of the aluminum frame and the anode, the anode lifting operation is highly mechanized and automated, and the anode is controlled The lifting operation precision is high, the contact voltage between the anode guide rod and the aluminum frame is reduced and the structure is simple, no arc is generated when the relative displacement between the anode guide rod and the aluminum frame occurs, and the purpose of the anode guide rod not moving in the left and right direction

Embodiment 1

[0049] Such as figure 1 As shown, the clamping frame 2 is set around the aluminum frame 1 with several conductors, and then the clamping frame 2 is connected with the anode lifting mechanism 3. The clamping frame 2 is composed of two upper and lower rows (the upper row of clamping frames 21 And the lower row of clamping frames 22), the upper and lower rows of clamping frames are connected by a support 23. A number of clamps 4 are arranged in the lower row of clamping frames 22. The clamps 4 are located between the aluminum frame 1 and the clamping frame 2. A number of hanging plates 5 or flexible chains 6 are arranged around the clamps 4. A number of anode guide rods 7 are arranged between the aluminum frame 1 and the upper and lower rows of clamping frames, and a number of anchors 8 are arranged between the anode guide rod 7 and the clamping frame 2, and the anchors 8 are located in the upper and lower rows. Row the top of the clamping frame. Such as figure 2 As shown, the ...

Embodiment 2

[0064] Such as figure 1 As shown, the clamping frame 2 is first arranged around the aluminum frame 1 with several conductors, and then the clamping frame 2 and the anode lifting mechanism 3 are connected. The clamping frame 2 is a row. A number of clamps 4 are arranged in the clamping frame 2. The clamps 4 are located between the aluminum frame 1 and the clamping frame 2, and there are several hanging plates 5 around the clamps 4 Or flexible chain 6. A number of anode guide rods 7 are also arranged between the aluminum frame 1 and the clamping frame 2, and a number of anchors 8 are arranged between the anode guide rod 7 and the clamping frame 2. The anchors 8 are located in the clamping frame 2. Inside the groove and the top of the clamping frame. Such as figure 2 As shown, the anode lead 7 is located between two adjacent holders.

Embodiment 3

[0077] Such as Picture 10 As shown, an anode lifting mechanism 3 is also provided around the clamping frame. The anode lifting mechanism 3 is located between the tank shell 10 and the upper structure 9 of the electrolytic cell. One end is connected to the tank shell and the other end is connected to the upper structure. The supporting frame is connected with the upper structure through the boom 11. When the anode lifting mechanism is activated, the upper structure of the electrolytic cell will be moved up and down, and the anode, hanging plate or flexible chain, clamping frame and clamp will be moved to the specified position simultaneously, and the clamping frame will be adjusted to the specified process Within the height range.

[0078] The anode lifting mechanism is a screw type lifting mechanism.

Abstract

A clamping and jacking apparatus of an aluminum electrolytic cell. A clamping frame (2) is provided around an aluminum frame (1) inside which several conductors are provided, and an anode lifting mechanism (3) used for adjusting the lifting and lowering of the clamping frame (2) is further comprised; several clamp holders (4) are provided between the aluminum frame (1) and the clamping frame (2), and at least one clamping wheel (41) is provided on a single clamp holder (4); several hanging plates (5) or at least one flexible chain (6) matched with the single clamp holder (4) and driven by the at least one clamping wheel (41) on the clamp holder (4) is further comprised; and a part of at least one of the hanging plates (5) or flexible chain (6) is maintained between the clamp holder (4) and the aluminum frame (1). The apparatus can reliably and stably clamp or lift / lower an anode while ensuring the aluminum frame (1) and the anode to be intact, keeps the contact voltage difference between an anode guiding rod and the aluminum frame (1) stable and low, and has a simple structure.

Description

Technical field [0001] The invention relates to the technical field of aluminum electrolysis, in particular to a clamping and tightening device for an aluminum electrolysis cell. Background technique [0002] The patent application number 201711220109.6 discloses a clamping frame of an aluminum electrolytic cell, in which several wheel clamps are arranged on the top or groove of the clamping frame, and the pressure clamp applied to the anode by the wheel clamp Hold and lift the anode, and can rely on the movement force generated by the rotation of the wheel holder to drive the anode up and down to lift the anode to a specified position. The clamping wheel in the wheel clamp is generally in linear contact with the aluminum frame. Under the condition that the clamping wheel exerts a certain pressure on the aluminum frame, due to the small contact area between the clamping wheel and the aluminum frame, the pressure on the aluminum frame is Very large, it will damage the aluminum fr...
