Non-contact temperature measuring device for monitoring of production process of quartz crucible

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of preparation of quartz crucibles, in particular to a non-contact temperature measuring device for monitoring the production process of quartz crucibles. Background technique [0002] In the quartz crucible manufacturing process of the arc method, since the melting process of the crucible is realized by arc discharge, the temperature in the melting mold is very high, and the temperature is as high as about 2000 degrees Celsius. The traditional thermocouple contact measurement method needs to be frequently Replacement of thermocouples, because thermocouple platinum rhodium thermocouple wires are expensive and have a short practical life, maintenance and replacement are inconvenient, and because the mold rotates at high speed during the manufacturing process of the quartz crucible, the traditional contact temperature measurement method will affect The molding of the quartz crucible has strict requirements on ...
