Device for rapidly screening plankton in seawater on site

Abstract

The invention relates to the technical field of screening equipment, and discloses a device for quickly screening plankton in seawater on site. The device comprises a screening box, a supporting plate is arranged in the screening box, a collecting box for collecting wastewater is arranged at the bottom of the supporting plate of the screening box, and a circulating hole for circulating the wastewater is formed in the supporting plate. A filter barrel with a hole in the top is arranged on the supporting plate, at least two sets of filter assemblies are detachably arranged on the supporting plate in a spaced mode in the radial direction of the filter barrel, and each filter assembly comprises a support assembled on the supporting plate and a screen arranged on the support. The aperture of the screen of each filtering assembly is gradually reduced in the direction away from the filtering barrel, and the circulating hole is formed between the filtering assembly away from the filtering barrel and the screen box. The screen of each filter assembly can screen plankton with the corresponding particle size, so that the plankton with the corresponding particle size is obtained and researched, the plankton with different particle sizes is screened at a time, the screening rate is increased, and the research requirement is met.

Description

Technical field[0001]The present invention relates to the field of screening equipment, and more particularly to a device for rapid screening of floating organisms in seawater on site.Background technique[0002]The floating creature is a slight organism that is suspended in the water. It needs to be observed by the microscope. It constitutes the ocean basic food chain, and the exploration of its survival is not only the balance of marine ecology, but also modern medical science has also been developed, so A floating biological production specimen is required to study its ecology.[0003]Announced Public Non-Patent Typographic Patent Publication No. CN204097142U discloses a floating animal sample filter, including a cylinder and a base, a base, and a cylinder having a screen, a base containing a ring corresponding to a cylinder and A sealing ring with a ring, an outer circumference of the ring or the inner wall of the ring, and a casing, the bottom of the cylinder contains an outer flap...

AI Technical Summary

Problems solved by technology

However, when studying plankton, each individual zooplankton can belong to one of a series of particle size groups, and the particle size spectrum composed of different biological particle sizes is useful for quantitatively estimating the growth, death, and nutritional processes of plankton. Significance, it is beneficial to analyze the functional groups and energy flow of the ecosystem, so it is necessary to filter the plankton in stages, and the existing zooplankton sample filter has a fixed size screen, which is difficult to meet the needs of the research
