[0002] Chemical raw material sampling equipment is generally aimed at liquid raw material, and since part of the raw material has certain corrosiveness and other harmfulness, sampling safety needs to be paid special attention during the sampling process.

[0003] In view of the above problems, there are various sampling equipment in the prior art, but all of them do not deviate from the pumping structure, that is, its implementation principle is to use the pumping equipment to always control the liquid sample in the sampling equipment, and to prevent the sample from splashing during the sampling process. But the disadvantages of such equipment are also obvious, especially after the pumping equipment sucks out the sample, due to the existence of the pressure in the pipeline, the residual liquid is inevitably left in the suction tube, and since the outer wall of the suction tube also directly contacts the material, when the sampling equipment is recycled, there is a problem of residual liquid recycling or difficult processing. The above problems will lead to waste of raw materials, especially the residual liquid still has the risk of splashing, which is not conducive to the safety of sampling and processing. At the same time, the sampling equipment in the prior art needs to participate in the electric equipment, and there are problems of high cost and high use cost. In view of the above problems, there is still a lack of corresponding solutions. SUMMARY

[0004] The utility model aims at overcoming the prior art deficiencies, providing a kind of chemical raw material sampling equipment with simple structure, flexible assembly, convenient to use, especially can improve sampling safety.

[0005] The equipment includes a plunger, which is the assembly basis of the equipment. In use, the plunger is used to plug into the filling hole and form a seal.

[0006] An air pump-in pipe and a sample pump-out pipe are provided on the plunger.

[0007] A gas pump-in mechanism is provided on the air pump-in pipe through a quick connector.

[0008] The lower part of the sample pump-out pipe passes through the plunger, and the upper part is integrally bent downward.

[0009] The effect achieved is that during sampling, the plunger is plugged into the filling hole, the sample pump-out pipe is deep into the liquid surface, air is pumped into the barrel through the air pump-in pipe by the gas pump-in mechanism, the pressure in the barrel increases, and the sample flows out through the sample pump-out pipe and is received by the sampling flask and other equipment.

[0010] After pumping out a certain amount of sample, the gas pumping mechanism is separated from the air pumping pipe, the sample in the sample pumping pipe is returned to the barrel, and the residual liquid in the downwardly bent pipe section is naturally flowed into the receiving device, and the sample recovery and sampling are completed.

[0011] The chemical raw material sampling device has the advantages that the sampling work of liquid raw materials is realized by low-cost equipment, the sampling process is safe, especially the recovery sampling equipment cannot splash, the equipment is convenient to use and convenient to clean, can be repeatedly used, and has great market promotion value.
