Abstract
The invention relates to a current measurement device, in particular to a device for online measurement of anode current distribution of an aluminum electrolysis cell. The device for online measurement of anode current distribution of the aluminum electrolysis cell structurally comprises an insulation connector, measurement contacts are arranged on the inner side of the insulation connector, and the outer side of the insulation connector is fixed on a fastening device. The device for online measurement of anode current distribution of the aluminum electrolysis cell has the advantages that the device is simple in structure, long in service life and easy to mount and demount, labor cost is reduced, and cell effect coefficient is decreased, so that energy is saved and consumption is reduced for aluminum manufacturers. Since an adjusting nut capable of fixing and adjusting tightness is mounted at the position of an opening, in the completely open state, one side of the fastening device is completely open, and further the device can be guaranteed to be smoothly and rapidly mounted on a guide rod; and in the locking state, close contact of the measurement contacts with the anode guide rod is guaranteed by means of gap adjustment.
Description
Technical field
The present invention relates to a kind of current measuring device, relate in particular to the device that a kind of on-line measurement aluminum cell anodic current distributes.
Background technology
For many years, the on-line monitoring problem of modern large-sized prebaked cell for aluminum-reduction processing parameter is a great problem of puzzlement world aluminum industrial development always, and especially the measurement of anodic current distribution is all the more so.
At present; Comparatively method in common is to be distributed with anodic current by the workman to pitch the equidistance millivolt pressure drop that regularly detects on the anode rod; To understand the distribution situation of electrolyzer inner anode electric current; And then analyze and judge whether each anode working of electrolyzer is normal, and abnormal anode of working is adjusted.The data that this method obtains are interrupted, and can't satisfy the requirement to the real-time monitoring of electrolyzer.Simultaneously, consuming time, the consumption power of this method.
Summary of the invention
In order to solve the problems of the technologies described above the device that the present invention provides a kind of on-line measurement aluminum cell anodic current to distribute, purpose is to monitoring of anode electrolytic cell real-time current and accurately control.
For reaching the device that above-mentioned purpose the present invention is achieved in that the on-line measurement aluminum cell anodic current distributes, constitute by following structure: the insulation linker, the inboard of insulation linker is provided with measuring contacts, and the insulation linker outside is fixed on the securing gear.
Described measuring contacts is a metallic conductor, and an end of measuring contacts is for being threaded, and measuring contacts is fixed through a screwed end and insulation linker, and the other end of measuring contacts is conical or spherical.
Described measuring contacts along anode rod sense of current fixed arrangement successively the insulation linker on.
Described insulation linker is through being bolted to the securing gear inboard.
Described securing gear is made up of following structure: the concave shape steel band, be provided with the snap close support in the end on a limit of concave shape steel band opening; The end of snap close support outboard end and handle is fixed through bearing pin; One end of the middle part of handle and union lever is fixed; One end of the other end of union lever and snap close ring is fixed, and the other end of snap close ring is enclosed within on the other side of concave shape steel band opening.
The end of the other side of described concave shape steel band opening outwards bends.
Described handle is a H shape.
Describedly be provided with setting nut passing on the union lever of handle.
Described snap close ring is connected through pin type mode with union lever.
Advantageous effect of the present invention: the present invention is simple in structure, long service life, be easy to installation and removal; Reduce cost of labor, reduce effect of grooves coefficient, realize that aluminium manufacturer is energy-saving and cost-reducing.Because installing, opening part can fix and regulate the setting nut of degree of tightness.Under full open position, securing gear has a side unlimited fully, and assurance device can be smoothly, be installed on the guide rod apace.Under locking state, can the adjusting play, guarantee that measuring contacts closely contacts with anode rod.
