Problems solved by technology

The traditional physical sieving method requires a large number of samples to be dried and sieved, which is time-consuming and laborious
And the dried sample may be broken or coagulated, changing the real particle size in water
In addition, the use of spectroscopic instruments to measure particle size is costly and has strict restrictions on the particle size range

Abstract

The invention discloses a riverway floating and suspended matter particle size-based sampling device. The device comprises a base and a combined sampling sieve, wherein a rotating support is arrangedon the upper surface of the base, a telescopic support is arranged on the rotating support, the tail end of the telescopic support is connected with the combined sampling sieve through a suspension support, the base is connected with a computer through a transmission line, and the computer is connected with a drying and weighing device through a transmission line. The device has the advantages ofon-site measurement, real and reliable data, simple operation, labor and economic cost saving and the like.

Description

technical field [0001] The invention belongs to the technical fields of water conservancy engineering and environmental engineering, and in particular relates to a sampling device for river floating and suspended solids by particle size. Background technique [0002] In order to ensure the health of the river ecological environment, some physical and biochemical indicators need to be monitored frequently. For some environmental assessment or scientific research purposes, the suspended and floating substances (such as sediment and microplastics) need particle size screening. The traditional physical sieving method requires a large number of samples to be dried and sieved, which is time-consuming and labor-intensive. And dried samples may break or coagulate, changing the true particle size in water. In addition, the use of spectroscopic instruments to measure particle size is expensive and has strict restrictions on the particle size range. Contents of the invention [00...
