Abstract

The invention belongs to the technical field of fully automatic equipment for fluid sampling, and in particular, relates to a fully automatic liquid sampling device and a use method thereof. A holding container is equipped with a second mechanical seal device, a sample retaining container is equipped with a first mechanical sealing device, the holding container and the sample retaining container are connected by a through shaft, and the through shaft is driven to rotate by a stepping motor; the sample retaining container is connected with a peristaltic pump through a sample retaining container gas connection pipe and a second peristaltic pump gas pipe, and the peristaltic pump communicates with the atmosphere through a first peristaltic pump gas pipe and is controlled to rotate by PLC; the through shaft is equipped with a through shaft sampling through hole as a sampling liquid circulation channel; a liquid suction pipe is wound on the through shaft, one end of the liquid suction pipe is connected with a tapered hammer having the interior with a hole, and the tapered hammer through hole communicates with the liquid suction pipe and the through shaft sampling through hole. The fully automatic liquid sampling device has the advantages of stable and reliable performance, stable structure, convenient assembly and disassembly, high adaptability and the like. The automatic control is performed by the PLC to ensure the authenticity and representativeness of a taken liquid sample, the sampling process can be carried out automatically, and the liquid is effectively guaranteed to be not residual in a sampling pipeline after sampling.

Description

technical field [0001] The invention belongs to the technical field of a fully automatic device for fluid sampling, and in particular relates to a fully automatic liquid sampling device and a using method thereof. Background technique [0002] Sampling is an important operation before material analysis and testing in the industrial production process. At present, in the fields of chemical industry, medicine, environmental protection, light industry, etc., manual sampling or automatic sampling has been used for sampling liquid materials. The results of manual sampling often have large errors and cannot reflect the real material characteristics, especially when the density distribution of liquids at different depths is uneven, so manual sampling is often not representative, and it is impossible to continuously take out liquids at different depths sample. In addition, manual sampling also has the disadvantages of cumbersome procedures, heavy workload, and poor timeliness. Aut...
