Abstract
The utility model discloses a temperature measuring device of a bromoacetyl bromide reaction vessel. The device includes a glass thermometer, a sleeve and a sealing ring. A lower end of the sleeve is an inclined port. The sleeve is sleeved out of the glass thermometer. The sealing ring is disposed between the glass thermometer and the sleeve. By using the temperature measuring device of the bromoacetyl bromide reaction vessel in the utility model, a temperature sensing position of the thermometer can contact with material directly and a transient temperature of the material can be detected accurately, so as to control the reaction temperature and enable the reaction to be processed in an allow range of technical conditions. Therefore, the product quality is improved substantially. The content of crude products is improved to more than 95 percents from about 90 percents. And the yield is improved by 3.5 percents.
Description
Technical field
The utility model relates to a kind of temperature measuring equipment, in particular a kind of temperature measuring equipment of bromoacetyl bromide agitated reactor.
Background technology
The temperature measuring equipment middle sleeve is used to protect thermometer; Sleeve pipe directly with the material contact, is put the oil of heat transfer usefulness in the sleeve pipe, the temperature-sensitive position of thermometer is immersed in the oil; Material carries out heat transferred through the oil of sleeve pipe and the inside; After balance, material temperature equates that with the temperature of oil thermometer just can accurately show material temperature.Because in the chemical and medicine industry production run, material has severe corrosive, the steel pipe outside of sleeve pipe is provided with enamel layer, and the heat conductivility of enamel is poor, and the temperature of material and oil reaches balance basically needs the long time, generally needs more than 15 minutes.The thermometer temperature displayed is not the transient temperature of material like this, but before a few minutes even the temperature of charge before tens minutes, requires very strict bromoacetyl bromide for temperature of reaction, and temperature exceeds 2 ℃ and will make a big impact to product quality.
The utility model content
The utility model purpose: the utility model provides a kind of temperature measuring equipment of bromoacetyl bromide agitated reactor, has realized the measurement to the real time temperature of material in reactor through the improvement to sleeve pipe.
Technical scheme: the utility model comprises glass-stem thermometer, sleeve pipe and O-ring seal, and the lower end of said sleeve pipe is the inclination port, and casing pipe sleeve is located at outside the glass-stem thermometer, and O-ring seal is arranged between glass-stem thermometer and the sleeve pipe.
The temperature-sensitive position of said glass-stem thermometer is positioned on the inclination port of sleeve pipe.
Angle between the inclination port of said sleeve pipe and the body of sleeve pipe is 30～60 degree.
Said sleeve pipe comprises steel pipe and polytetrafluoroethylene floor, and polytetrafluoroethylene floor is coated on the surface of steel pipe, realizes the fire resistant anticorrosive of sleeve pipe.
Said O-ring seal is a silica gel sealing ring, and O-ring seal is as supporting and sealing silica gel material fire resistant anticorrosive.
Beneficial effect: the utility model is compared prior art and is had the following advantages: use the utility model that the temperature-sensitive position of thermometer is directly contacted with material; The ability accurate response goes out the transient temperature of material; Thereby temperature of reaction is controlled, made to be reflected in the process conditions allowed band and carry out, product quality is had significantly improve; The content of semifinished product is brought up to more than 95% by about 90%, and yield improves 3.5 percentage points.

Embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises glass-stem thermometer 1, sleeve pipe 2 and O-ring seal 3, and the lower end of said sleeve pipe 2 is the inclination port, and sleeve pipe 2 is sheathed on outside the glass-stem thermometer 1, and O-ring seal 3 is arranged between glass-stem thermometer 1 and the sleeve pipe 2.
The temperature-sensitive position of glass-stem thermometer 1 is positioned on the inclination port of sleeve pipe 2; As shown in Figure 1; The direction of arrow is the direction of Flow of Goods and Materials; The low side of the inclination port of sleeve pipe 2 is in face of the direction of Flow of Goods and Materials, and the temperature-sensitive position of glass-stem thermometer 1 directly contacts material, the real-time temperature of charge of measurement that can be promptly and accurately.
Angle between the inclination port of present embodiment middle sleeve 2 and the body of sleeve pipe 2 is 45 degree.
O-ring seal 3 is silica gel sealing rings, and the up and down two ends of O-ring seal 3 in sleeve pipe 2 are provided with respectively, is used for supporting and sealing silica gel material fire resistant anticorrosive.
