Technical field：
The technical field of reactor is the utility model is related to, is filled more specifically to the automatic sampling on a kind of reactor
Put.
Background technology：
The especially intermittence type polymerization reaction during chemical polymerization of current most chemical industry producer is sampled
When, usually it is sampled during the course of the reaction from bottom valve or kettle overhead-valve or pipeline position, but it is mostly that high temperature is high to chemically react
The operating mode of pressure, kettle overhead-valve or bottom valve sampling are directly opened, it is very dangerous, so as to propose to increase on the probe tube on the outside of reactor
If branched pipe, and the probe tube in branched pipe and branched pipe both sides is mounted on stop valve, then pressure-reducing valve is installed on branched pipe,
Then turn off and take vertically between two stop valves on probe tube from the pressure in by reactor by the solution of reactor
Stop valve on sample pipe, opens the pressure-reducing valve on branched pipe and stop valve takes solution, but the easily residual solution in pipeline, can shadow
Ring the result of lower sub-sampling.
Utility model content：
The purpose of this utility model and provides the automatic sampling on a kind of reactor aiming at the deficiency of prior art
Device, cleaning structure is installed on its sampler, the pipeline of sampling, sub-sampling under the influence of avoiding are cleaned after sampling terminates
As a result.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of automatic sampling device on reactor, including reactor, plugged and fixed has vertical probe tube on reactor,
The lower end of probe tube is plugged in reactor, and the upper end of probe tube stretches out reactor and is fixed with water tank, taking on the outside of reactor
Sample pipe is fixedly connected sequentially from bottom to up the first stop valve, air driven pump and the second stop valve, the first stop valve and air driven pump it
Between probe tube on be fixedly connected with drain pipe, be fixedly connected with the 3rd stop valve on drain pipe, one end of return duct, which is fixed, to be connected
It is connected on the drain pipe between the 3rd stop valve and air driven pump, the other end is fixedly connected between air driven pump and the second stop valve
On probe tube, check valve is fixedly connected with return duct.
Described air driven pump uses one-way pump, and the direction of air driven pump flows to the second stop valve by the first stop valve, described time
Check valve direction in flow tube flows to drain pipe by probe tube.
Described the first stop valve, the second stop valve and the 3rd stop valve uses pneumatic stopping valve, probe tube and goes out liquid
Pipe is connected by threeway, and the caliber of probe tube is equal to the caliber of drain pipe.
Choke valve is fixedly connected with probe tube on the outside of the reactor, choke valve is located at the downside of the first stop valve.
The beneficial effects of the utility model are：
1st, it optimizes existing automatic sampling structure, and cleaning structure is installed on its sampling structure, clear after sampling terminates
The pipeline of sampling is washed, the result of sub-sampling under the influence of avoiding.
2nd, it also can be suitably used for the sampling operation for not having pressure in reactor.
