Automatic liquid separating sampler

Abstract

The invention discloses an automatic liquid separating sampler which comprises a vertically arranged container body, wherein a plurality of necking down parts are arranged on the container body at intervals from top to bottom; an inner cavity of the container body is divided into a plurality of liquid separating cavities by the necking down parts, and the volumes of the liquid separating cavities are equal; every two adjacent liquid separating cavities are communicated with each other by the corresponding necking down part; the top of the liquid separating cavity arranged at the upmost part is provided with a liquid inlet; the side walls of all the liquid separating cavities are respectively provided with a liquid outlet pipe; all the liquid outlet pipes are respectively provided with a sampling valve; all the liquid separating cavities are respectively and internally provided with a hollow floating ball; the diameters of the hollow floating balls are larger than the inner diameters of necking down openings or sampling holes formed in the tops of the corresponding liquid separating cavities; floating ball baffles deviating from the positions of the necking down openings are respectively fixed on the inner walls of the bottoms of the liquid separating cavities. As the automatic liquid separating sampler is used, all samples can be collected at a time within a work period, and additional power and a specially-assigned responsible person are not needed in the sample collecting process, so that the defects in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to an automatic liquid-separating sampler for sampling liquid. Background technique [0002] In the fields of scientific research and development, it is often necessary to take a certain amount of samples at intervals of a certain volume for liquids such as leachate, resin-adsorbed liquid, and desorbed liquid to analyze the composition of the liquid in different time periods. When the liquid that needs to be sampled has a slow flow rate and a small flow rate, the sampling work cycle may be as long as several days or months. Although the workload is small, it requires a special person to be responsible and takes up human resources. Contents of the invention [0003] The purpose of the present invention is to provide an automatic liquid-separating sampler which does not need a special person to take samples at regular intervals. [0004] The technical solution of the present invention is: an automatic liquid-separating sampler, c...
