The invention discloses a non-
contact temperature measuring device for monitoring of a production process of a
quartz crucible. The non-
contact temperature measuring device comprises an installing base, a sensor installing support and an insulation board, wherein the installing base is fixedly connected on a
quartz sand distributing device, and the sensor installing support is perpendicular to the installing base and is fixedly connected on one side of the installing base. The insulation board is located over a
quartz crucible mold and under the sensor installing support. A non-
contact type temperature sensor and a temperature display instrument are arranged above the sensor installing support, wherein the temperature display instrument is connected with the non-
contact type temperature sensor. A
light sensing tube is installed below the sensor installing support and is located under the non-
contact type temperature sensor and penetrates through the insulation board and extends toward the top face of the
quartz crucible mold. The insulation board is installed on one side, close to the middle position of the
quartz crucible mold, of the
light sensing tube. The non-
contact temperature measuring device for the monitoring of the production process of the
quartz crucible is compact in structure, reasonable in design, convenient to achieve, operate and use, beneficial for improving forming accuracy of the quartz
crucible, low in maintenance cost, high in temperature measuring accuracy, good in using effect, and convenient to popularize and use.
