The gap of the two sides of beautiful pipe sleeve and tubular type inboard wall of burner hearth is uniformly arranged multiple thermocouples in corundum pipe sleeve, and corundum pipe sleeve peripheral hardware is set
One thermocouple, corundum pipe sleeve inner sleeve set corundum bar, and corundum bar extends downwardly out tubular type burner hearth and connect with displacement sensor, corundum
Pipe sleeve bottom is arranged snorkel, and tubular type burner hearth bottom is arranged support plate, and the bottom side of support plate is arranged balance weight, on balance weight
Balancing pole is connected by shaft, one end of balancing pole is connect with the bottom of corundum bar, and the other end and counterweight of balancing pole slide
Connection.
The displacement sensor includes guide groove, guide rod and sliding block, and the center of guide groove opens up sliding slot, is arranged in sliding slot at it
The sliding block of upper sliding, slider top are connect with guide rod, and hall device is arranged in the bottom of sliding block, and guide rod is connected to rigid outside sliding slot
Permanent magnet is arranged in the bottom of beautiful bar bottom, sliding slot.
The displacement sensor bottom is arranged by bottom plate, and bottom plate is bakelite plate.
The utility model has the beneficial effects that the utility model places sample using vertical heater vertically, prevent sample greatly in height
Temperature is lower to generate axial bending deformation, influences accuracy of measurement, corundum pipe sleeve is arranged inside and outside thermocouple, it is ensured that uniform in heating temperature
When larger sample measurement accuracy, so that corundum bar is born constant force during entirely at this time using the method that counterweight pressurizes,
The variation of sample can be reliably transmitted, after adapting to measurement expansion and the first contraction of the big sample of shrinkage and dusty raw materials
The performance of expansion.
