Abstract
The utility model relates to a device for detecting temperature, which is inserted into the furnace wall of a blast furnace. The utility model comprises a flange, a flange short pipe, a protective sleeve pipe movably arranged in the flange and the flange short pipe and fixed to the flange by an adjusting nut, two thermocouples inserted into the protective sleeve pipe and adjusting valves, wherein the flange and the flange short pipe are inserted into the furnace wall of the blast furnace. One thermocouple is used for detection, and the other thermocouple is used for standby. The adjusting valves are arranged on the protective sleeve pipe and the flange short pipe, and are respectively connected with a grouting pipe to grout the protective sleeve pipe and the flange short pipe and to thoroughly seal the thermocouples and the protective sleeve pipe, and the protective sleeve pipe and the mounting hole of the furnace wall of the blast furnace. The connection of the thermocouple protective sleeve pipe and the flange of the utility model adopts a clamped sheathing type, and the utility model can adjust the insertion length according to the actual wall thickness. The utility model detects the temperature accurately, prevents gas leakage and extends the service life.
Description
Technical field
The utility model relates to the thermal thermal temperature checkout equipment, particularly is used for the temperature detection of high temperature detection as equipment such as blast furnaces.
Background technology
The head protection pipe of existing thermopair generally all is an enclosure-type; Nei Bu thermopair test side is unsettled in gas like this; the accuracy of temperature detection just can't guarantee; and it is also slow to the response of variation of temperature; in addition the back is installed because the outside does not have flange short tube grouting mouth yet; just gapped between protecting tube and the hole like this, inner coal gas will leak, and all brings hidden danger for ordinary production and safety.
Summary of the invention
The purpose of this utility model is to design a kind of temperature-detecting device, and sealed against leakage when high temperature detects can increase the service life.
For achieving the above object, technical solution of the present utility model is, a kind of temperature-detecting device is inserted in the blast furnace furnace wall, and it comprises that flange and flange short tube are inserted in the blast furnace furnace wall; Protective casing is movably set in flange and the flange short tube, and is fixed on the flange by setting nut; Thermopair is inserted in the described protective casing; Variable valve is arranged on protective casing and the flange short tube, and connects grout pipe respectively, makes grouting in protective casing and the flange short tube, and thermopair and protective casing, protection pipe box and blast furnace furnace wall mounting hole are thoroughly sealed.
Further, of the present utility model have two thermopairs to be inserted in the described protective casing, and a conduct detects, and another is as standby.
Described two thermopairs are not isometric together with dress in protective casing.
The beneficial effects of the utility model:
Thermocouple protective casing of the present utility model is connected the employing bite type with flange, can insert length according to actual wall thickness adjustment; Temperature detection is accurate, prevents gas leak, and prolong serviceable life.
Description of drawings
Fig. 1 is a structure cut-open view of the present utility model.
Embodiment
Referring to Fig. 1, a kind of temperature-detecting device of the present utility model is inserted in last furnace shell 10, the cooling wall 11, and it comprises protective casing 1, flange 2 and flange short tube 3, two thermopairs 4,5; Wherein, flange 2 and flange short tube 3 are inserted in the blast furnace furnace wall; Protective casing 1 is movably set in flange 2 and the flange short tube 3, and is scheduled on the flange 2 by setting nut solid 6; Two thermopairs 4,5 are inserted in the described protective casing 1; Variable valve 7,8; it is a stop valve, is arranged on protective casing 1 and the flange short tube 3, and connects grout pipe 9 respectively; make grouting in protective casing 1 and the flange short tube 3, thermopair 4,5 and protective casing 1, protection pipe box 1 are thoroughly sealed with blast furnace furnace wall 10 mounting holes.
Can carry out inner and outer pipes grouting after the installation; make thermopair 4; 5 with protective casing 1; protective casing 1 and last furnace shell 10; the mounting hole of cooling wall 11 thoroughly seals; and two thermopairs 4; 5 adopt not isometric iron of fine quality dress; one as detecting; one as standby; because temperature inside reaches thousands of degree during the blast furnace ordinary production; inner cooling wall 11 protection tiles in furnace wall will have coming off in various degree along with the postponement of time; thermopair front-end protection sleeve pipe 1 also can wear and tear like this; in case can adopt standby thermopair 5 to detect so thermopair 4 damages, guarantee that the normal detection of furnace wall temperature shows at once.
