Abstract

The invention provides an air-cooled thermocouple verification furnace with an insulation layer and a preparation method thereof, comprising a verification furnace body, a furnace tube, an insulation isolation tube, an electric heating wire, an insulation layer, an air-cooled tube, a high-speed exhaust fan, an exhaust window, an air intake window. Its advantage is that four air-cooled pipes are arranged symmetrically in the insulation layer, and a high-speed exhaust fan is installed at one end of each air-cooled pipe, which can efficiently discharge the heat stored in the insulation layer of the thermocouple verification furnace, thereby rapidly reducing the temperature of the thermocouple verification furnace. temperature, which improves the utilization rate of equipment, greatly improves the efficiency of thermocouple verification, and is easy to manufacture and use, without any auxiliary operation, which is conducive to the automation of the production process.

Description

technical field [0001] The patent of the invention belongs to the technical field of temperature measurement, and in particular relates to an air-cooled thermocouple verification furnace with an insulating layer. Background technique [0002] The verification furnace is a common temperature element verification equipment. At present, the verification furnace is widely used in the fields of industrial and agricultural production and scientific research experiments. The basic structure of the traditional verification furnace is that the heating wire is wound outside the furnace tube, and then the insulation isolation tube is covered, and the insulation material is filled between the insulation isolation tube and the shell to form an insulation layer. In order to keep the temperature of the temperature field in the furnace tube constant and the rate of change small, the insulation layer is specially designed to have a certain thickness and uses a heat insulation material with ...
