Problems solved by technology

[0002] At present, the sampling devices used in the field of online water quality analysis on the market mainly collect instantaneous water samples, which cannot reflect the solubility of water pollution within a period of time, and the equal proportion sampler is mainly used for the collection and storage of water samples, and cannot accurately analyze the water quality of online analysis instruments. For sample supply, of course there are very few (according to the current market knowledge, Shijiazhuang Derun Environmental Protection and Beijing Jinpeng Huanyi two companies) have equa

Abstract

The invention discloses a sampling device for equal proportions of mixed water samples used in determination of an on-line water quality analyzer. The sampling device includes a first pipe, a second pipe, a quantitative small water pump, a mixing bucket and a sampling line. The second pipe is provided with a first electric ball valve, a Y-shaped filter, a manual sampling port and a tee joint overflow mouth, and the tee joint overflow mouth is communicated with the quantitative small water pump, the quantitative small water pump is connected with a tee joint electric ball valve, the tee joint electric ball valve is connected with the mixing barrel, the mixing barrel and a drainage electric ball valve are communicated through a sample supply pipe, the sampling line is connected with the sample supply pipe, and the sampling line includes a first sampling line and a second sampling line. The sampling device adopts multistage overflow filtering for pretreatment, and quantitatively adopts the brushless microflow quantitative small water pump for sampling, so that the stability and the accuracy of the device are improved, and the sample collection time consumption of the on-line analyzercan be reduced while sampling of the equal proportions of mixed water samples.

Description

technical field [0001] The invention relates to the technical field of water quality sampling, in particular to a sampling device for measuring equal-proportion mixed water samples by an online water quality analyzer. Background technique [0002] At present, the sampling devices used in the field of online water quality analysis on the market mainly collect instantaneous water samples, which cannot reflect the solubility of water pollution within a period of time, and the equal proportion sampler is mainly used for the collection and storage of water samples, and cannot accurately analyze the water quality of online analysis instruments. For sample supply, of course there are very few (according to the current market knowledge, there are Shijiazhuang Derun Environmental Protection and Beijing Jinpeng Huanyi two companies) with equal-proportion samplers for mixed sample supply. They all use peristaltic pumps for sampling, and the sampling range is very limited. , the sample ...
