Description
Technical Field
The invention relates to the technical field of aluminum electrolysis, in particular to a device and a method for driving an anode guide rod to move.
Background
In the production process of the aluminum electrolysis cell, the continuous and firm clamping of the anode is the most basic requirement for accurately controlling the cell voltage and keeping the stability of the electrolysis cell, but when the sparking problem occurs between the anode guide rod and the anode, the smooth conduction of current into the anode is slightly influenced, and the firm clamping of the anode is seriously influenced, so that the anode slides downwards.
Patent CN 106894055 a discloses a continuous aluminum frame anode aluminum electrolytic cell with built-in conductor, which comprises a clamping frame, a clamping frame I and an anode guide rod to continuously and firmly clamp the anode. When the anode rod moves down to the lowest position as the anode is consumed and lowered, the anode rod must be lifted to a designated position, but the lifting operation is complicated and the working efficiency is low.
In order to omit the operation of lifting the anode rod and avoid the adverse effect on continuously clamping the anode and driving the anode caused by the problems of electric arc, spark and the like possibly occurring between the anode rod and the anode, a device for clamping the anode and a device for conducting current to the anode are generally separated, for example, a patent CN 108070879A discloses a clamping frame of an aluminum electrolysis cell, a wheel type clamp is directly contacted with an aluminum frame, the anode rod is contacted with the aluminum frame through a filler, and the anode is independently moved to a specified position by the pressure and the movement force applied to the anode by the movement of a clamping wheel; patent CN 108285087 a discloses a clamping and jacking device for aluminum electrolytic cell, the clamp holder is contacted with the aluminum frame through a hanging plate or a flexible chain, the anode guide rod is directly contacted with the aluminum frame, and the anode is moved to the designated position independently by the pressure and the moving force applied to the anode in the operation process of the clamping wheel.
In the two patents, when the clamping wheel drives the anode to move, in order to ensure that the current is stably led into the anode, the pressure between the anode guide rod and the aluminum frame is basically kept unchanged, the anode descending difficulty is increased by huge friction force between the anode guide rod and the aluminum frame, and the wheel type clamp holder or the clamp holder for clamping the anode and the compressor or the jacking device for jacking the anode guide rod are two independent mechanisms which are positioned at different positions, so that the structure is complex.
Disclosure of Invention
The invention provides a device and a method for driving an anode guide rod to move, aiming at achieving the purposes that the anode guide rod does not generate sparking in the moving process and the anode is continuously and firmly clamped on the premise of simple structure and simple and convenient operation.

Further, a filler with electric conductivity is added in the gap between the at least one clamping frame and/or the at least one anode bus bar frame and the anode, and a sealing member used for wrapping and fixing the filler is further included, so that the stable uniformity of current introduced into the anode on the anode guide rod is improved.

When the anode guide rod is close to the lower limit, the lowermost end part of the anode guide rod is removed; when the total length of the anode guide rod is close to the lower limit value, the metal block and/or the metal plate is connected to the upper part of the anode guide rod, so that the purpose of segmented and cyclic upward movement of the anode guide rod is realized under the condition that the anode guide rod and the anode are in close contact and the sparking problem is not generated between the anode guide rod and the anode.
