Description
Technical field
Patent of the present invention relates to the device and method of measuring liquidus temperature on a kind of used for aluminium electrolysis on-site real-time.
Background technology
In the aluminum electrolysis, liquidus temperature is meant in electrolyte coagulation or the fusion process, first dropping liquid mutually or the temperature of solid phase when generating, the degree of superheat is meant actual temperature and liquidus temperature poor of electrolysis.The liquidus temperature and the degree of superheat are unusual important parameters, and they directly influence the energy consumption index of the stability and the aluminum electrolysis of electrolytic tank, and therefore, it is pair great with the aluminum electrolysis control Significance quick and precisely to grasp the electrolytic tank liquidus temperature and the degree of superheat.
But, be difficult to in-site measurement because in the aluminum electrolysis, the electrolyte melt temperature is high, corrosivity is strong, composition changes soon.Domestic enterprise carries out the theoretical calculate liquidus temperature through molecular proportion and alumina concentration that the laboratory chemical examination draws, and result who draws and actual value differ bigger, and directive significance is not strong.Mainly there is following defective in existing measuring equipment: 1. it is high to measure cost; 2. accuracy of measurement is low, and poor repeatability, error are big.
The utility model content
The utility model problem to be solved provides the primary crystal temperature measurement device that a kind of measurement result is accurate, cost is low.
In order to address the above problem, the technical scheme that the utility model provided is:
A kind of measurement mechanism of liquidus temperature; Comprise measure portion and sampling part, described measure portion and sampling part are separated from each other, and described measure portion comprises connecting rod, thermometer, lead, thermopair; Thermopair comprises thermopair body and thermocouple probe; The end that one end and the thermopair of connecting rod do not have probe is fixedly connected, and thermometer is fixedly connected with connecting rod, connects through lead between thermometer and the thermopair; Described sampling part comprises ST and ST handle, and ST is fixedly connected with the ST handle.
Preferably, described thermopair body is a bending, and angle is that 85 degree are to 95 degree.
Preferably, described ST inwall has heat-insulation layer.
Preferably, on the opening of said ST draw-in groove is arranged.
The beneficial effect of the utility model is: 1. measurement result is accurate.(1) thermopair is separated with ST, shortened thermopair is invaded bubble in electrolyte time, avoided the extent of corrosion of electrolyte to greatest extent, thereby guaranteed the accuracy of measurement result thermopair; (2) increase heat-insulation layer at the ST inwall, reduced electrolytical cooldown rate, reduced the pace of change of electrolyte curve, thereby can pure and freshly see the electrolyte temperature change curve, accurately read the liquidus temperature value; (3) draw-in groove on the ST opening can the steady heat galvanic couple, prevents that thermopair from rocking, to guarantee the accuracy of liquidus temperature; This device low cost of manufacture, thereby also reduced the measurement cost; 3. easy to use, efficient is high.This device can use at the electrolysis scene whenever and wherever possible, meets industrial characteristics and demand efficiently.
