Abstract
The utility model relates to a temperature measuring device which comprises a thermometer, wherein the thermometer is sheathed with a metallic sleeve which presents a hollow solid shape, and the inside wall and the outside wall of the metallic sleeve are processed by the preservative treatment. The temperature reading part of the thermometer is exposed at the upper part of the metallic sleeve. The temperature measuring end of the thermometer at the lower part of the thermometer is cut off with a cylinder wall of the sleeve to form a protecting tube along the direction of an axle wire. A plurality of small holes are formed on the protecting tube. The protecting tube block the temperature measuring end of the thermometer. The temperature measuring device is installed in a reaction still. The stirring direction of the protecting tube is aligned with the flowing direction of reaction mass.
Description
Technical field
The utility model relates to a kind of temperature measuring equipment, relates in particular to a kind of temperature measuring equipment that can measure the temperature of the bigger reaction mass of viscosity in reactor.
Background technology
In traditional chemical process, when carrying out condensation reaction in reactor, the control of the temperature of reaction mass is one of key that can chemical reaction successful, and the measuring method of temperature generally adopts glass-stem thermometer or thermopair.In course of reaction, reaction mass generally compares thickness, and glass-stem thermometer is very easy to fracture, and thermopair is a metal material, in the environment of soda acid, is very easy to be corroded.Existing solution is metal sleeve on the outer cover of common thermometer, heat-transfer oil is housed in the sleeve pipe, and this thermometer is immersed in the oil, though can not fracture like this, but thermometer must can accurately measure material temperature after metal sleeve and heat-transfer oil reach temperature balance.And the heat transfer coefficient of sleeve pipe and oil is discrepant, so just can not promptly and accurately measure the temperature variation of reaction mass, is not easy to control normally carrying out of reaction.
Summary of the invention
The purpose of this utility model is to provide a kind of temperature measuring equipment, is used in the temperature of measuring reaction mass in the reactor, can thermometer be fractureed because of the reactant thickness, can reflect variation of temperature rapidly timely simultaneously.
For achieving the above object, the utility model provides a kind of temperature measuring equipment, and it comprises a thermometer, an outside sheathed metal sleeve of this thermometer, and this metal sleeve is the three-dimensional shape of a hollow, and this metal sleeve inner and outer wall has all been done preservative treatment.This thermometer read the top that isothermal segment is exposed to metal sleeve, clip one section sleeve pipe barrel at metal sleeve temperature of lower instrumentation Wen Duan along the axis direction and form a pillar, offer several apertures on this pillar.This pillar blocks the thermometric end of this thermometer.This temperature measuring equipment is installed in the reactor, and this pillar is by the flow direction of the direction that stirs over against reaction mass.
The utlity model has following beneficial effect: this temperature measuring equipment is installed in the reactor, install according to mixing direction, pillar is over against the flow direction of this reaction mass, to block most of reaction mass, have only a spot of reaction mass from the aperture of this pillar, to pass, the reaction mass of therefore big viscosity can not impose on the excessive external force of mercury thermometer and mercury thermometer is fractureed, the direct contact reaction material of the thermometric end of this mercury thermometer simultaneously can promptly and accurately reflect the temperature variation of reaction mass; On the other hand, this thermometer places sleeve pipe, thermometer read the top that isothermal segment is exposed to metal sleeve, conveniently read the temperature of reaction mass.

Fig. 2 is the synoptic diagram of the utility model temperature measuring equipment.
Fig. 3 is the synoptic diagram of the utility model temperature measuring equipment other direction.
Embodiment
See also Fig. 1 to Fig. 3, a kind of temperature measuring equipment 1, it is used in and measures the reaction mass temperature of (figure does not show) in the reactor (figure does not show).Reaction mass in this reactor moves along a direction under the effect of stirring apparatus, and reaction mass viscosity is bigger.
This temperature measuring equipment 1 comprises a mercury thermometer 12, an outside sheathed metal sleeve 14 of this mercury thermometer 12.These metal sleeve 14 inner and outer walls have all been done preservative treatment.This metal sleeve 14 is the column shape of a hollow.This thermometer 12 read the top that isothermal segment 10 is exposed to metal sleeve 14, conveniently read the temperature of reaction mass.The thermometric end 16 of these metal sleeve 14 contiguous mercury thermometers 12 is clipped the long sleeve pipe barrel of 20-30cm and is formed a pillar 20 along the axis direction, and the thermometric end 16 of mercury thermometer 12 is exposed outside metal sleeve 14.This pillar 20 blocks this thermometric end 16.Offer several apertures 22 on this pillar 20.
When temperature measuring equipment 1 being installed to when being immersed in the reaction mass in the reactor, with the flow direction of this pillar 20 over against this reaction mass, this pillar 20 will block most of reaction mass, have only a spot of reaction mass from the aperture 22 of this pillar 20, to pass, the reaction mass of therefore big viscosity can not impose on mercury thermometer 12 excessive external force and mercury thermometer 12 is fractureed, the thermometric end 16 direct contact reaction materials of this mercury thermometer 12 simultaneously can in time reflect the temperature variation of reaction mass rapidly.
Claims (3)
1, a kind of temperature measuring equipment, it comprises a thermometer, an outside sheathed metal sleeve of this thermometer, it is characterized in that: this thermometer read the top that isothermal segment is exposed to metal sleeve, clip one section sleeve pipe barrel at metal sleeve temperature of lower instrumentation Wen Duan along the axis direction and form a pillar, offer several apertures on this pillar.
2, temperature measuring equipment according to claim 1 is characterized in that: this pillar blocks the thermometric end of this thermometer.
