Description

Closed sampler Technical Field The utility model relates to the technical field of chemical production, in particular to a closed sampler. Background In the light aromatic disproportionation link, the higher the purity of the product is, the better the product is obtained by subsequent reaction, so that the purification operation is carried out on each raw material at each ring node, and the purity of each raw material obtained by the coal oil ring node is only about 80 percent. The main purification mode adopts a refining tower to carry out purification, and in the purification process, samples of the purified raw materials are required to be sampled and detected so as to achieve the purpose of subsequent reaction. At present sampling mode, at cauldron body bottom installation pipeline and valve, open the valve sample can, this mode is too simple rough to the sampling process is quantitative sampling, if need sampling personnel stare at the scale tightly, reduces the waste that excessive sampling caused, consequently can cause certain harm to the sampler, especially crude benzene purification link has certain danger, for this we have proposed a airtight sampler and solved above-mentioned problem. Disclosure of utility model The application provides a closed sampler, which solves the problems that when a kettle body is used for sampling, single pipeline sampling is easy to cause residue, the accuracy of a sample is insufficient, and the sample is easy to contact sampling personnel. The application provides a closed sampler, which comprises a box body, wherein a sampling pipe is arranged in the box body, the inlet and outlet ends of the sampling pipe penetrate through the box body and are positioned at the outer side of the box body, a glass pipe is arranged on the sampling pipe, scales are arranged on the glass pipe, a discharging pipe is further arranged on one side of the sampling pipe, a sampling head is arranged at one end of the discharging pipe, valves are arranged on the inlet and outlet ends of the sampling pipe and the discharging pipe, a limiting structure for placing a sampling bottle is further arranged on the box body, a sealing cover is arranged on one side of the box body, and a control structure corresponding to the valve of the sampling head is arranged on the sealing cover. Preferably, the limiting structure comprises a positioning plate fixed in the box body and a limiting plate placed in the box body. Preferably, the control structure comprises an adjusting knob mounted on the sealing cover, the adjusting knob penetrates through the sealing cover, a limiting groove is formed in the adjusting knob, and the limiting groove corresponds to a valve handle of the valve. Preferably, a glazing is provided on the cover. Preferably, the sampling tube is supported and fixed in the box body through a supporting frame.
