Description
Technical field
The utility model relates to a kind of temperature-detecting device, is meant material temperature pick-up unit in the large-scale calciner rotary kiln of oil, chemical industry or gas industry especially.
Background technology
At present, in the known large-scale calciner rotary kiln kiln system, the temperature of charge pick-up unit has single thermocouple temperature measuring apparatus and three thermocouple temperature measuring apparatus in the rotary kiln.Because the filling rate of material does not reach 100% in the kiln body, single thermocouple temperature measuring apparatus rotates in the process in a week at the kiln body, it is to be inserted in the material that the thermocouple temperature measurement end has only a fraction of time, remaining time is neither in material, the temperature of measuring is discontinuous a section temperature value, is difficult to show, control and regulating; For three thermocouple temperature measuring apparatus, the installation site of three thermopairs is the point that is mutually 120 degree angles on the longitudinal profile, the copper ring of two conductions is respectively a sealed whole body, measured value is the mean value of three thermocouple measurements, but always there is a thermopair to detect less than material temperature, make measured value and actual value differ greatly, influenced accurate grasp and control to temperature of charge in the kiln, its result has influenced the calcination reaction process.
The utility model content
The purpose of this utility model is accurately to detect the deficiency of temperature of charge in the rotary kiln at existing rotary kiln temperature of charge pick-up unit, a kind of instantaneous temperature signal accurately of process stream and reasonable in design in the rotary kiln that records is provided, rotary kiln temperature of charge pick-up unit simple in structure, easy to operate.
The utility model comprises the thermopair that is installed on the rotary kiln kiln body, a pair ofly be installed on conductive copper on the kiln body, contact two conduction sliding brush that slide with two conductive copper and be loaded on insulating segment on the copper ring, it is characterized in that:
A, at least two thermopair five equilibriums are arranged and are installed on the circumference of kiln health check-up measuring point longitudinal profile, and two compensating wires are welded in respectively on two copper rings on each thermopair;
B, be arranged on the conductive copper with the insulating segment five equilibrium of quantity such as thermopair, each insulating segment is relatively between adjacent two thermopairs.
In addition, the insulating segment on two copper rings respectively with this copper ring on the current-carrying part smooth transition, it adopts the insulating material that can be fully analog electrical signal or digital electric signal is cut off, the smooth contact of sliding brush is passed through.
Copper ring is fixed on the kiln body by fixture, and fixture is made up of with the steel part that the other end is connected with copper ring the heat insulation subassembly of centre, the groove guiding principle that an end is connected with the kiln body.
The support that has spring on sliding brush bag brush and its, two brushes respectively with place support on compensating cable is connected, the brush employing can transmit the conductive material or the compound substance of analog electrical signal or digital electric signal and make.
When the kiln body rotates that nethermost two thermopairs are on the horizontal linear in the week, and at this moment two thermocouple temperature measurement ends are inserted in the material fully, and the position at the insulating segment place between this two thermopair is exactly the contacted position of sliding brush and copper ring.Always can detect the temperature signal of single thermopair when sliding brush is between two adjacent insulating segments in rotary kiln rotates like this, when sliding brush forwards insulating segment to, because at this moment nethermost two thermopairs are on the horizontal linear, detected temperature of charge is identical, and satisfy relative motion length that sliding brush contacts with copper ring length between sliding brush and the insulating segment greater than insulating segment on the copper ring, therefore detected is the mean value of nethermost two parallel-connected thermo couple signals, equal the measured temperature of each thermopair, therefore rotate in the process in a week at the kiln body, always can detect the instantaneous value of temperature of charge.
The utility model effect
1, the transient temperature of any point material in the rotary kiln kiln body be can measure exactly, temperature display alarm, control and adjusting therefore can be used for.
2, this device is reasonable in design, simple in structure, easy to operate, with low cost.
