Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0017] As shown in Figure 1, the blast furnace cross temperature measuring thermocouple consists of a set of temperature measuring thermocouple 1, temperature measuring thermocouple mounting flange 2, ferrule 4, steel belt 9, mounting sleeve 6, and connecting positioning spring 8. One end of the installation sleeve 6 is closed, and a connection flange 3 is welded on the other open end, and the connection flange 3 is connected with the installation flange 2 . A steel belt 9 placed in the middle of the installation sleeve 6 is fixedly installed in the middle of the installation flange 2, and a set of thermocouple tubes 5 for temperature measurement are inserted into both sides of the steel belt 9 through the ferrule 4 installed on the installation flange 2. In the casing 6, the temperature measuring sensors 7 of the temperature measuring thermocouple 1 ar...

The invention discloses a blast furnace cross temperature thermocouple which comprises a group of temperature thermocouples which are provided with flanges, cutting sleeves, steel belts, assemble tubes and springs for connection and positioning. In the assemble tube with one end sealed is provided with a steel belt for fixing flanges; in the tubes of the steel belt two sides, a group of temperature thermocouples are inserted and fixed via flanges; each temperature sensor on the head of the temperature thermocouples is connected with a compression spring which is placed with temperature sensor and presents as X type; the temperature thermocouples facing down are tightly stuck to the tube inside wall, herein, the two ends of the compressing spring are respectively contacted with the steel belt surface and the tube inside wall, and under the action of the spring, the temperature sensor head is tightly connected with the tube inside wall; on the install flange opens a prolate ellipsoid slot for install adjustment.
Description
technical field [0001] The invention relates to a temperature-measuring thermocouple device, in particular to a temperature-measuring thermocouple device for the upper layer of a blast furnace. Background technique [0002] At present, the temperature measuring thermocouple used on the blast furnace adopts a set of temperature measuring thermocouples placed in a cross position. The temperature measuring sensor of the thermocouple is directly inserted on the top of the blast furnace. The scouring of particles is generally used for three to six months before being washed out and needs to be replaced. However, the replacement of the cross temperature measuring thermocouple can only be carried out after the furnace is shut down, which will greatly reduce the utilization rate and production efficiency of the blast furnace, and increase the cost of steelmaking. Therefore, need to have a kind of simple in structure, long service life, convenient installation and maintenance, do no...
