Temperature measuring device for bottom surface of tin bath of floating glass manufacturing line

Abstract

The invention discloses a temperature measuring device for a bottom surface of a tin bath of a floating glass manufacturing line. The temperature measuring device comprises an armored thermocouple, amounting seat and a spring, wherein one end surface of the mounting seat has an accommodation groove, the mounting seat has a first through hole penetrating the accommodation groove and the other endsurface of the mounting seat, the armored thermocouple is arranged in the first through hole, a temperature measuring end of the armored thermocouple penetrates out from one end of the accommodation groove, the spring sleeves on the armored thermocouple and is limited between the accommodation groove and the temperature measuring end of the armored thermocouple, one end surface of the mounting seat having the accommodation groove has a magnetic body, when the magnetic body is absorbed on a to-be-measured device, and the temperature measuring end of the armored thermocouple is pushed to contactwith the to-be-measured device through the restoring force generated by the compressed spring. The temperature measuring device is advantaged in that the structure is simple, the temperature measuring end closely contacts with the to-be-measured device, and mounting and dismounting are convenient.

Description

technical field [0001] The invention relates to a temperature measuring device, in particular to a temperature measuring device for the bottom surface of a tin tank of a float glass production line. Background technique [0002] In the existing glass production process, because the float glass produced by the float production process has good thickness uniformity, the transparency of the product is also relatively strong, and the surface is relatively smooth after tin surface treatment, so it is widely used in various glass Manufacturer. [0003] In the float glass production line, it is necessary to inject tin liquid into the tin bath. In order to ensure the quality of the produced glass, it is necessary to measure the temperature of the tin bath at any time. In the prior art, the temperature measurement of the tin bath generally uses a thermocouple The temperature measuring end is welded on a hexagonal nut, and then the nut is welded to the bottom of the tin bath for temp...

AI Technical Summary

Problems solved by technology

[0004] The existing technology has the following disadvantages: 1. Since the tin bath is generally placed in the basement of the float glass production line, the basement is full of various driving motors, blowers, large pipes and valves, etc., due to limited space and high ambient temperature (over 60°C), which is not conducive to the welding and installation of ordinary products; 2. Since the temperature measuring end of the thermocouple is welded to the bottom of the tin bath through a nut, there may be poor contact between the temperature measuring end of the thermocouple and the bottom of the tin bath. The measured temperature difference is large; 3. The temperature measuring end of the thermocouple is welded to the nut, which will make the thermocouple unable to be reused, and the installation and disassembly are complicated
