Description

Technical Field

[0001] The utility model belongs to the technical field of temperature measuring devices, in particular to a temperature measuring device for a vacuum aluminum bucket scale of an RH furnace. Background Art

[0002] RH vacuum furnace is a heat treatment equipment commonly used for metal materials. It is widely used in the fields of metal processing and material research. In the production process, the valve on the vacuum system cannot be closed tightly, resulting in wind tunnel phenomenon. As a result, the sensor of the vacuum aluminum bucket scale, a key equipment in the production of RH furnace, is often burned out due to high temperature. Due to the burnt sensor, the aluminum bucket scale cannot detect the weight of the aluminum material normally, which brings great inconvenience to production and also brings maintenance difficulties. It is necessary to add a set of temperature measuring equipment to monitor the temperature so that it can be handled in time when the temperature is too high and the vacuum aluminum bucket scale sensor is easily burned out.

[0003] Most of the existing temperature measurement devices in furnaces are single-point temperature measurement devices, and the temperature measurement accuracy is not precise enough. The few multi-point temperature measurement devices have a large number of temperature measurement sensors, which will cause a higher frequency of damage in the high temperature environment of the furnace. Replacement is cumbersome and easily delays work efficiency. Utility Model Content

When the equipment starts to run, the adjusting threaded rod 3 can be twisted at any time for adjustment, and multi-directional temperature measurement is performed at different depths in the furnace;

[0027] A liquid cooling main channel 302 is opened in the adjusting threaded rod 3, and the entrance of the liquid cooling main channel 302 is located at the top of the threaded rod outside the vacuum chamber 1 and extends to the inside of the temperature measuring disk 4. The liquid cooling main channel 302 is connected to a liquid cooling component, and a plurality of infrared temperature measuring probes 401 are clamped by the liquid cooling component. While improving the stability of the temperature measuring probes, the infrared temperature measuring probes 401 can be cooled to reduce the damage rate of the infrared temperature measuring probes 401 in a high temperature environment.

[0028] In one embodiment, see Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the liquid cooling component includes an upper microchannel 304 and a lower microchannel 305, the upper microchannel 304, the lower microchannel 305 and the liquid cooling main channel 302 are connected in parallel, a plurality of first clamping parts 306 are arranged on the upper microchannel 304, and a plurality of second clamping parts 307 are arranged on the lower microchannel 305, and an infrared temperature measuring probe 401 is clamped between each first clamping part 306 and each second clamping part 307, and the first clamping part 306 and the second clamping part 307 are both arc-shaped in design, which is more closely fitted with the outer wall structure of the infrared temperature measuring probe 401;
