Summary of the invention
The purpose of this invention is to provide temperature of charge assay method in a kind of novel rotary furnace stove, can measure each section material temperature in the rotary furnace exactly, long service life, precision height, and maintenance is changed conveniently.
Technical scheme of the present invention is: temperature of charge assay method in a kind of novel rotary furnace stove, it is characterized in that thermopair and protection tube stretch out outside the rotary furnace in the position of the no heating jacket of rotation outer wall of rotary furnace, behind flange seal, connect the wireless temperature transmitter by signal cable; The wireless temperature transmitter is fixed on the position of certain distance on the rotation outer wall of rotary furnace by support, and rotates with rotary furnace; Thermopair collecting temperature data-signal, be connected to the wireless temperature transmitter by signal cable, be transmitted on the gateway by the wireless temperature transmitter again, signal is incorporated into control system the most at last, control system is according to the operational throughput of the outer thermophore of the Signal Regulation stove that receives, thus each section material temperature in the robotization control stove.
For guaranteeing thermometric authenticity; the thermopair suspension that is installed in the protection tube is fixed on the rotary furnace cylinder inboard wall; protection tube is fixed by the pipe clamp that is welded on the rotary furnace cylinder inboard wall; the pipe clamp slightly larger in diameter is in the protection tube diameter; thermopair and protection tube retractable in pipe clamp is so avoided the thermal expansion of rotary furnace cylindrical shell to the influence of thermopair and protection tube
Temperature probe on the thermopair closely contacts with the protection tube inwall, to avoid temperature hysteresis and accurately to measure temperature of charge in the stove.
Thermopair length can suitably be adjusted according to technological requirement, and when requiring point for measuring temperature more for a long time, the optional majority of thermopair is propped up or the multiple spot thermopair.
Since the wearing and tearing of furnace high-temperature and material, the material that protection tube and pipe clamp adopt and the rotary furnace cylindrical shell is same or more high-grade high-abrasive material, and protection tube should adopt thicker wall thickness.
