Abstract
The utility model provides a novel continuous temperature measurement of molten steel ventilates and pops one's head in, belongs to temperature measurement technical field. The utility model discloses a casing be provided with two independent gas passages in the casing, first gas passage is the cooling air passageway, and the second gas passage is dustproof wind passageway, the air supply of cooling air passageway is compressed air, and the air supply of dustproof wind passageway is nitrogen gas or other uncontaminated inert gas. The utility model discloses two kinds of air supply independent utilities have reduced the cost that the user used the air supply, prevent that light path and optical system receive the pollution, have lengthened the maintenance period of device, have improved the accuracy of system.
Description
Technical field
The utility model belongs to technical field of temperature measurement, particularly relates to a kind of novel liquid steel continuous temperature measurement ventilation probe.
Background technology
For the sensor of continuous measurement of molten steel temperature, due to sensor when carrying out continuous measurement of molten steel temperature close to molten steel surface, its environment temperature is higher, in use needs to cool to sensor; Meanwhile, because the temperature tube of continuous measurement of molten steel temperature can volatilize flue dust in high temperature environments, block light path, even pollute eyeglass, therefore in Continuous Temperature Measurement Sensor for Liquid use procedure, connect ventilation duct, ventilating and cooling is carried out to it, dispel flue dust, improve measuring accuracy, extend sensor serviceable life.
Chinese patent CN201075035Y discloses a kind of high temperature continuous thermometering device, the dust-proof gas of its purging adopted be anhydrous, without the higher nitrogen of wet goods purity requirements or inert gas, this gas also provides cooling of optics temperature probe simultaneously; Purge dust-proof desired gas amount compared with total gas flow, proportion is 5 ~ 10%, and optics temperature probe cool to gas without particular/special requirement, pressurized air just can meet the demands.Therefore, adopt a kind of gas carry out cooling of optics temperature probe simultaneously and purge dust-proof, cause source of the gas high cost.
Utility model content
For prior art Problems existing, the utility model provides a kind of novel liquid steel continuous temperature measurement reducing source of the gas cost to ventilate and pops one's head in.
To achieve these goals, the utility model adopts following technical scheme, and a kind of novel liquid steel continuous temperature measurement ventilates and pops one's head in, comprise housing, in described housing, be provided with two independently gas passages, the first gas passage is cooling air passage, and the second gas passage is dust-proof wind passage; The source of the gas of described cooling air passage is pressurized air, and the source of the gas of dust-proof wind passage is the inert gas of nitrogen or other cleaning.
The exit of described dust-proof wind passage tilts to axle center, and it is 38 ° with axial angle.
The beneficial effects of the utility model:
Because the utility model is provided with two independently gas passages in described housing, the first gas passage is cooling air passage, and the second gas passage is dust-proof wind passage; The source of the gas of described cooling air passage is pressurized air, and the source of the gas of dust-proof wind passage is the inert gas of nitrogen or other cleaning; Two kinds of sources of the gas independently use and reduce the cost that user uses source of the gas, prevent light path and optical system contaminated, extend the maintenance period of device, improve the accuracy of system.
Accompanying drawing explanation
Fig. 1 is the structural representation of novel liquid steel continuous temperature measurement of the present utility model ventilation probe;
In figure: 1-housing, 2-cooling air passage, the dust-proof wind passage of 3-, 4-ventilated box, 5-lens set, 6-air curtain.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of novel liquid steel continuous temperature measurement ventilates and pops one's head in, and comprises housing 1, is provided with two independently gas passages in described housing 1; First gas passage is cooling air passage 2, and the gas in cooling air passage 2 blows out along housing 1, cools to whole ventilation probe; Second gas passage is dust-proof wind passage 3, and dust-proof wind passage 3 plays the effect of induced-draft smoke-exhaust, ensures that thermometric light path cleans with the eyeglass of optical module not contaminated, for optical system purges dust-proof.Cooling air passage 2 is connected with ventilated box 4 respectively with dust-proof wind passage 3, is provided with the source of the gas that two independence is controlled in ventilated box 4, and a source of the gas is cheap pressurized air, and another source of the gas is the inert gas of nitrogen or other cleaning; The source of the gas of described cooling air passage 2 is pressurized air, and the source of the gas of dust-proof wind passage 3 is the inert gas of nitrogen or other cleaning.
The exit of described dust-proof wind passage 3 tilts to axle center, and it is 38 ° with axial angle; Owing to have employed this kind of structure, just make described dust-proof wind passage 3 form an air curtain 6 in lens set 5 front end, air curtain 6 can stop that extraneous dust does not pollute lens set 5.
Claims (2)
1. a novel liquid steel continuous temperature measurement ventilates and pops one's head in, and it is characterized in that comprising housing, be provided with two independently gas passages in described housing, the first gas passage is cooling air passage, and the second gas passage is dust-proof wind passage; The source of the gas of described cooling air passage is pressurized air, and the source of the gas of dust-proof wind passage is the inert gas of nitrogen or other cleaning.
2. novel liquid steel continuous temperature measurement according to claim 1 ventilates and pops one's head in, and it is characterized in that the exit of described dust-proof wind passage tilts to axle center, and it is 38 ° with axial angle.
