Embodiment 1

[0038] An embodiment of the present invention provides a device 100 for adjusting the balance of anode groups in a continuous anode electrolytic cell, which includes more than two anode group balance adjustment units 10, and more than two anode group balance adjustment units 10 are respectively located in the anode groups of the continuous anode electrolytic cell Two opposite sides of 200, such as figure 1 shown. The structure of each anode group balance adjustment unit 10 is exactly the same, and the specific number of anode group balance adjustment units 10 depends on the load of the anode group 200 (i.e. the weight of the anode group). At least four anode group balance adjustment units 10 should be provided for the anode group 200. For an anode group 200 with a small load (including only a single anode), two anode group balance adjustment units 10 can meet the balance adjustment requirements. The specific number of anode group balance adjustment units 10 is not limited in ...

Embodiment 2

[0051] Based on the same inventive concept, this embodiment provides a method for adjusting the balance of the anode group, which is implemented based on the device 100 for adjusting the balance of the anode group in the above-mentioned embodiment 1 for a continuous anode electrolyzer. see Figure 5 , the method includes the following steps:

[0052] During the operation of the continuous anode electrolyzer, detect the balance state of the anode group of the continuous anode electrolyzer, and judge whether the anode group has unilateral inclination or local unevenness;

[0053] When the anode group tilts on one side, the anode group balance adjustment unit 10 on the side that needs to be adjusted is controlled to operate, and the dial wheel 5 is driven to rotate through the power device 1, and the dial wheel 5 meshes with the anode group to drive the inclined side of the anode group to rise or fall, eliminating Tilt, so as to achieve the balance of the whole anode group;

Abstract

The invention discloses a device and method for adjusting the balance of anode groups in a continuous anode electrolyzer. The two opposite sides of the anode group; the anode group balance adjustment unit includes a power device, a transmission assembly and more than one dial, and the power device, transmission assembly and dial are connected in sequence according to the direction of power transmission; the transmission assembly is provided with the same number of clutches as the number of dials One or more clutch devices are correspondingly connected with more than one dial to transmit power; the dial is meshed with the anode group, so that when the dial rotates, the part of the anode group that engages with the dial is driven up or down. The invention controls the dial corresponding to the required adjustment position of the anode group through the power device and the clutch device, and the dial moves the anode group for overall adjustment or local fine-tuning, avoiding the tilt and unbalance of the anode group during operation in the prior art question.

Description

technical field [0001] The application belongs to the technical field of aluminum electrolysis, and specifically relates to a device and method for adjusting the balance of an anode group in a continuous anode electrolytic cell. Background technique [0002] Aluminum electrolytic production can be divided into three categories: side-inserted anode bar self-baking tank, top-inserted anode bar self-baking tank and pre-baked anode tank, among which pre-baked anode aluminum electrolytic cells dominate. The prebaked anode aluminum electrolytic cell is developing towards large-scale and modernization, but it still belongs to discontinuous operation, the process flow is long, the production cost is high, the frequent replacement of the anode will lead to high work intensity, and it will also affect the stability of the electrolytic cell, thereby affecting Technical and economic indicators of aluminum electrolysis. [0003] Compared with the pre-baked tank, the biggest advantage of...
