Special temperature-reduction accelerator for horizontal type thermocouple testing furnace

Abstract

The invention relates to a special temperature-reduction accelerator for a horizontal type thermocouple testing furnace. The special temperature-reduction accelerator comprises a cooling pipe, a blower, a blower actuator and a temperature-measurement controlling instrument. One end of the cooling pipe is inserted into a furnace tube of the thermocouple testing furnace and penetrates out of an opening of the furnace tube; the other end of the cooling pipe is fixedly connected with the blower; the blower is controlled to be started / stopped by the blower actuator; the temperature-measurement controlling instrument is mounted at a rear side of the blower; the temperature-measurement controlling instrument controls the blower actuator; an outer wall of the cooling pipe is provided with a groove; a temperature-measuring thermocouple is arranged in the groove; the working end of the temperature-measuring thermocouple is located in the middle of the cooling pipe; and the reference end of the temperature-measuring thermocouple is connected with the temperature-measurement controlling instrument through a leading wire. The cooling pipe penetrates through the furnace tube of the horizontal type thermocouple testing furnace, thus the heat dissipation is even, the temperature-reduction efficiency is high, and the stress damage to the furnace tube of the testing furnace caused by too-fast local cooling which is generated by using fans for directly blowing the furnace tube of the testing furnace is avoided; the cooling pipe is in seamless connection with the blower, thus the process of heat dissipation by air cooling is ensured to be energy-saving and efficient; and with the arrangement of the temperature-measurement controlling instrument and the blower actuator, automatic temperature measuring, automatic stopping and overrun controlling over temperature-reduction rate can be realized.

Description

technical field [0001] The invention relates to a high-efficiency energy-saving tool device in the field of temperature measurement, which is specially matched with a horizontal thermocouple verification furnace, in particular to a special cooling accelerator for the horizontal thermocouple verification furnace. Background technique [0002] When using a thermocouple verification furnace for thermocouple verification, it is often necessary to raise the temperature of the verification furnace to 800°C and above and keep it for a long time, so that a large amount of heat energy is stored in the thermocouple verification furnace. When the verification of the next batch of thermocouples needs to be carried out as soon as possible after the verification of a batch of thermocouples, the cooling of the verification furnace becomes a particularly time-consuming problem. It will take at least 5 hours to reduce the temperature of the verification furnace whose working temperature has ...
