A self-priming large-flow biological pump device and method based on magnetic drive

Abstract

The invention discloses a self-priming large-flow biological pump device based on magnetic drive and a method thereof. The device includes a control power supply, a sampling pump, a protection bracket and a sedimentation assembly, and the control power supply, the sampling pump and the sedimentation assembly are all fixed on the protection bracket; The sampling pump includes an external pipeline, a diversion casing, a multi-pole stator and a hollow rotor; the rotating helical blades can suck the external fluid into the working driving chamber through the water inlet slot of the interceptor, and flow out from the outlet of the working driving chamber to form a At the same time, it drives the external fluid from the external pipeline into the hollow chamber of the diversion housing; the settling assembly includes a buffer pipeline connected in sequence, a cylindrical filter screen and a settling bottle; the hollow motor passes through the circuit and is used to provide power. Control power connection. The invention is small in size and compact in structure, and can be mounted on other large-scale equipment to filter organisms in the water body separately, and can also be locked and self-suctioned by manipulators or other equipment with tracking organisms.

Description

technical field [0001] The invention belongs to the technical field of marine biological sampling, and in particular relates to a self-priming large-flow biological pump device based on magnetic drive and a method thereof. Background technique [0002] The unique chemosynthetic biological community is bred near the cold spring mouth of the seabed hydrothermal vent, which is rich in biological gene resources and is a natural gene treasure house. Because of its extremely special environment, which is very similar to the environment of the early earth, it is considered a "laboratory" for cutting-edge scientific research such as the origin of life. Most of the large organisms in these communities are invertebrates, and the larvae of invertebrates are planktonic larvae. Therefore, obtaining larvae of hydrothermal or cold seep organisms is one of the important ways for deep-sea life science research. [0003] Due to the complex micro-topographic environment of the seabed hydrothe...

Problems solved by technology

However, this technology uses a centrifugal pump to drive a large volume of water for filtration, and the high-speed rotating blades during sampling will cause greater damage to the fragile invertebrate larvae, easily breaking biological samples, resulting in inaccurate survey data; in addition, the sampling The filter adopts a straight line pipeline, which is easy to cause damage to the mesh port and extrusion of biological samples when filtering with large water flow
