Drawings
FIG. 1 is a schematic structural view of an aluminum liquid temperature thermocouple of the present invention.
Wherein: 1-protective tube, 2-junction box, 3-thermode, 4-sleeve, 5-support, 6-mounting seat, 7-graduated scale, 8-electric push rod.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.
As shown in fig. 1, the utility model discloses the aluminium liquid temperature thermocouple of the preferred embodiment, including the thermocouple body, the thermocouple body is equipped with thermode 3 including the protection tube 1 and the terminal box 2 that are connected in the protection tube 1, still includes sleeve pipe 4, support 5 and sets up telescopic machanism on the support 5, the other end of support 5 can be connected on the outer wall of smelting furnace or connect on other articles, only needs to guarantee aluminium liquid temperature thermocouple is located the smelting furnace in the top of aluminium liquid can. The sleeve 4 is made of a high-temperature resistant and corrosion resistant material, and preferably, the sleeve 4 is made of ceramic. Sleeve 4 detachably cup joints protection tube 1 is last, the outer wall of sleeve 4 is equipped with the scale mark, terminal box 2 is connected telescopic machanism. Preferably, the telescopic mechanism is an electric push rod 8, and a telescopic rod of the electric push rod 8 is connected with the junction box 2.
The aluminum liquid temperature thermocouple based on the technical characteristics has the advantages that the sleeve 4 is sleeved on the protection tube 1, and the sleeve 4 is made of high-temperature-resistant and corrosion-resistant materials, so that the high-temperature-resistant and corrosion-resistant performances of the thermocouple are improved, the thermocouple can measure in aluminum liquid for a long time without being damaged, and the aluminum liquid pollution is avoided. Meanwhile, the outer wall of the sleeve 4 is provided with scale marks and is connected with the telescopic mechanism, so that the measuring depth of the thermocouple can be flexibly adjusted during measurement, and accurate depth information can be obtained through the scale marks, so that the measuring depth and the measuring precision of the thermocouple are fully ensured.
