Fully-closed automatic sampling system

Abstract

The invention discloses a fully-closed automatic sampling system, which comprises a structure main body, the structure main body comprises a sampling device, a sealed container and an automatic control box, and the lower end of the sampling device is connected with the sealed container; the sampling device comprises an automatic lifting air cylinder, a sampling pipeline is arranged at the lower end of the automatic lifting air cylinder, a sampling valve is arranged on one side of the sampling pipeline, a sampling bottle is arranged at the lower end of the sampling valve, and a first connecting pipe for achieving communication is arranged between the sampling valve and the sampling pipeline. A second connecting pipe for realizing communication is arranged between the sampling valve and the sealed container; a cleaning valve communicated with the sampling pipeline is arranged on the other side of the sampling pipeline; a sampling device connector is arranged at the upper end of the sealed container; the full-closed automatic sampling system disclosed by the invention is extremely high in automation degree, can realize complete actions in the whole sampling process by one-key operation, and ensures that no leakage risk of a medium in the whole sampling process exists.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a fully enclosed automatic sampling system. Background technique [0002] As China's legal and regulatory requirements for environmental protection become more and more standardized, the production units that use reactors for chemical reactions have more standardized requirements for the sampling process of material media during the reaction process and reduce any possible environmental risks and operator injuries. risk. At present, there are three methods of conventional reactor sampling in the world: one is manual sampling, using a sling to add samples and directly enter the reactor from the top of the reactor for sampling; the other is to use huge pipelines and valves to form a relatively bulky pipeline Structure, sampling is completed by pumping vacuum, and the taken samples are put into sampling bottles for testing and inspection; the third is to use a sampling sys...

Problems solved by technology

[0003] Although the above three sampling schemes are compared with the patent of the present invention, they can all realize the online sampling of the reactor, but these three traditional sampling schemes all have the following disadvantages: cumbersome operation, complicated system pipeline, bulky volume, immobile, It can only be fixed on the reactor equipment, and cannot be cleaned thoroughly. There are many dead areas and effusions, which will affect the final results of the test and inspection; the cumbersome operation process may easily lead to human misoperation, resulting in accidents or inaccurate sampling. , increasing the potential danger to the operator
