Problems solved by technology

[0003] The above-mentioned synchronous lifting structure of the anode guide rod and the bus bar currently used has the following disadvantages: first, the anode bus bar needs to be frequently switched, and each switch needs to be opened and clamped dozens of times, which is labor-intensive and difficult to operate. The second is that before and after the transfer of the busbar, due to the stress deformation of the anode lifting frame and the anode busbar, the bottom palm of the anode is not in the same position before and after the transfer, causing the pole distance to change and affecting the normal production index; the third is that the operating position temperature is relatively high High, the working environment is poor; Fourth, the cumulative transmission error is large during the up and down conversion

Embodiment 1

[0014] Example 1 Rolling drive aluminum electrolytic cell anode guide rod continuous lifting device

[0015] Such as figure 1 , 2 shown. The anode guide rod 3 with a square cross-section is adopted. In the figure, the anode guide rod continuous lifting device is composed of two driven wheels 2, 4 and a driving wheel 1. Only two driven wheels are drawn in this figure, which is enough for small-sized aluminum electrolyzers. When the driving wheel rotates, under the action of friction, the anode guide rod 3 will move up and down, and the up and down movement of the guide rod will drive the driven wheel to rotate thereupon. For the anode guide rod, the driven wheel can not only play the role of guiding and reducing friction; more importantly, it can play the role of transmitting current. When the anode needs to be replaced and the anode guide rod is taken out, first cut off the power supply of the guide rod, clamp the top of the guide rod with the clamp on the crown block, and...

Embodiment 2

[0016] Example 2 Gear and rack drive aluminum electrolytic cell anode guide rod continuous lifting device

[0017] Such as image 3 shown. Adopt square section anode guide rod 3, load onto rack plate 7 on the two sides of guide rod corresponding to driving gear 5 and moving gear 6,8. Only one driving gear and two driven gears are shown in the figure, but multiple driving gears and driven gears can be provided if necessary. When the driving gear rolls, the anode guide rod moves up and down through the engagement of the gear and the rack, and the up and down movement of the guide rod drives the driven gear to roll. Multiple driven gears can not only transmit current to the anode guide rod, but also clamp the guide rod and play a guiding role. When it is necessary to replace the anode guide rod, similar to the previous scheme, first cut off the current of the driven gear, then clamp the anode guide rod with the clamp on the crane, turn the driven gear to loosen the anode guide...

Embodiment 3

[0018] Example 3 Continuous Lifting Device for Anode Guide Rod of Aluminum Electrolyzer with Spiral Drive

[0019] Such as Figure 4 , 5 shown. The anode guide rod 3 with a circular cross-section is adopted. In the figure, the anode guide rod continuous lifting device is composed of an externally threaded sleeve 9, a bevel gear nut 10, a fixed sleeve 11, a support plate 12 and an active bevel gear 13. The anode round guide rod 3 is fixed together with the outer threaded casing. When the active bevel gear drives the matching bevel gear to rotate under the drive of the frequency conversion speed regulating motor, they will move up and down relative to the bevel gear. The bevel gear itself It is stuck in the fixed sleeve on the support plate and cannot move up and down. The anode busbar supplies power to the anode through the support plate and the fixed sleeve. When it is necessary to replace the anode and take out the anode guide rod, move the active bevel gear backward, cut...

Abstract

A method for continuously lifting an anode rod of an aluminium cell is characterized in that a positive bar is fixed; in addition, a device which is matched with the positive bar and can cause the anode rod to continuously lift in the device is arranged to cause the anode rod to continuously lift in a wide range. The invention also provides a device implementing the method. The device comprises the positive bar and is characterized in that the device is fixed with the positive bar; in addition, a mechanism which is connected with the upper part of the anode rod and causes the anode rod to do up-and-down movement is arranged; when the mechanism uses rolling driving mode or gear and rack gear driving mode, the section of the anode rod is square; when the mechanism takes screw-driven mode, the section of the anode rod is circle. The method and the device overcome the shortcomings of the current used anode rod and a busbar elevation synchro drive to cause that the anode rod can automatically continuously adjust according to the burning loss of the anode, thus ensuring the stable running of the aluminium cell.

Description

technical field [0001] The invention belongs to the technical field of lifting the anode of an aluminum electrolytic cell, and relates to an anode guide rod lifting method and device for an aluminum electrolytic prebaking cell. Background technique [0002] At present, during the electrolysis process, the anode guide rod of the aluminum electrolytic cell needs to drop continuously due to the oxidation and burning of the anode, and the anode bus bar will also drop accordingly. When the anode consumption reaches a certain position, the anode large busbar may contact the horizontal cover plate of the electrolytic cell and short circuit, at this time, the position of the anode guide rod is the limit position for its descent. In this case, the anode system is not allowed to continue to descend. At this time, it is necessary to open the clamps on each guide rod, and then use the anode busbar lifting frame to lift the anode busbar that has reached the lower limit to the upper limit...
