A kind of insulation sampler
Technical field
The utility model relates to a kind of chemical industry verifying attachment, especially a kind of insulation sampler.Be applicable to that the insulation from pipeline liquid towards intermediate product is taken a sample in chemical process.
Background technology
In the arginine production run, need carry out inspection by sampling to a kind of liquid intermediate product from middle pipeline, but the Tc of this intermediate product is higher, often in sampling process, crystallization will take place, and makes check to carry out.
The utility model content
The technical matters that the utility model will solve provides a kind of insulation sampler that can carry out heat tracing to sampling liquid.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of insulation sampler; Comprise a double tubular container, its internal layer top connects sampling liquid input tube and input valve, and the bottom connects sampling liquid output pipe and output valve; Its outer bottom connects the heating liquid input pipe, and top connects the heating liquid efferent duct.
Be provided with the thermometer that to measure the heating liquid temperature.
Adopt the beneficial effect that technique scheme produced to be: double-decker to be set, in skin, to have heating liquid to flow through, the sampling liquid of internal layer is carried out heat tracing, make it crystalline polamer can not take place, can guarantee carrying out smoothly of chemical industry check.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model.
Wherein, 1-internal layer; The 2-liquid input tube of taking a sample; 3-imports valve; The 4-liquid output pipe of taking a sample; The 5-output valve; 6-is outer; 7-heating liquid input pipe; 8-heating liquid efferent duct; The 9-thermometer.
Embodiment
The utility model comprises a double tubular container; Its internal layer 1 top connects sampling liquid input tube 2 and input valve 3; The bottom connects sampling liquid output pipe 4 and output valve 5, and its outer 6 bottoms connect heating liquid input pipe 7, and top connects heating liquid efferent duct 8.
Be provided with the thermometer 9 that to measure the heating liquid temperature.
Close the sampling liquid output valve 5 of the utility model, be communicated with the chemical pipeline of sampling liquid input tube 2, open input valve 3, draw an amount of sampling liquid in the internal layer 1 of double tubular container with circulation sampling liquid; Through the skin 6 of heating liquid input pipe 7 input heating liquids to the double tubular container; Again through 8 outputs of heating liquid efferent duct; Utilize heating liquid that the sampling liquid in the internal layer 1 is carried out heat tracing, make sampling liquid identical, observe temperature shown in the thermometer 9 with the temperature of heating liquid; Make sampling liquid when discharging ST, crystallization not take place, can guarantee carrying out smoothly of chemical industry check.
