Problems solved by technology

Since the supernatant must be sucked off manually when separating the liquid in the separating funnel, the sediment in the lower layer will be stirred if you are not careful, and the phytoplankton will be siphoned out, resulting in a large error in the separation of phytoplankton

Embodiment 1

[0015] As shown in Fig. 1, phytoplankton separator of the present invention comprises a sealed container, and container is made up of tubular body 1 and cap 2, and container is provided with water sample sedimentation area A and concentration area B from top to bottom, in The bottom of the enrichment zone B is provided with an outlet 10 with a valve 9, and a disc-shaped floating body 6 is arranged in the body 1 of the container. The diameter of the float 6 is slightly smaller than that of the body 1, and the inner wall of the body 1 is above the concentration zone B. There is a protruding part 8 used to prevent the floating body 6 from floating down. The protruding part 8 is a tapered closing shape. A liquid suction head 7 with a suction hole 5 is fixed under the floating body 6. The liquid suction head 7 is connected to a length adjustable The spiral hose 11 is connected, the spiral hose 11 protrudes from the cap, and its protruding part is an external connection pipe. The end...

Embodiment 2

[0017] Another structure of the present invention is shown in Figure 2. The difference from Embodiment 1 is that the protruding part 8 above the concentrated area B of the container body 1 is a bump (or convex ring), and the liquid suction head 7 passes through the A screw rod is connected with 16 floating bodies 6, and the distance between the rotating liquid suction head 7 and the floating bodies can be adjusted, and the inflation device 13 is separately arranged on the cap 2 of the container.

[0018] working principle:

[0019] The main body 1 and the cap 2 form the airtight container of the phytoplankton separator. After pouring the water sample into the container, tighten the cap 2 and the main body 1, close the valve 14 on the external connection of the hose 11, and use the pump 15 to inflate The device 13 inflates the container, and after the inflation is completed, since the inflating device 13 is provided with a one-way valve, after the pump is removed, a certain air...

Abstract

The invention discloses a phytoplankton separator, which comprises a sealed container, wherein the container is provided with a water sample precipitation region and a concentration region, an outlet provided with a valve is arranged at the bottom of the concentration region, a floating body is arranged in the container, the inner wall of the container is provided with a projected part above the concentration region, a liquid suction head with a suction hole is fixed under the floating body, the liquid suction head can be connected with a hose, the hose has the adjustable length and is connected with an external connection pipe, the external connection pipe is at least provided with a valve, the container is provided with an inflating device, and the inflating device is used for inflating the container and is provided with a one-way valve. The invention has the advantages that the separated clear liquid at the upper layer is automatically discharged through the air pressure in the container, the liquid suction head can be controlled not to be in contact with the concentrated phytoplankton in the liquid discharge process, and the invention perfectly solves problems of easy siphon of the phytoplankton, poor precipitation effect and greater error caused by easy stirring of precipitate at the lower layer because of manual operation in the liquid discharge process in the prior art.

Description

technical field [0001] The invention belongs to a liquid-solid separation device, in particular to a phytoplankton separator. Background technique [0002] Both aquaculture and water environment protection research require the collection of phytoplankton samples and the solid-liquid separation of phytoplankton and water. At present, phytoplankton are separated by the natural sedimentation method of a cylindrical separatory funnel after collection. When precipitating, first fix the separating funnel in the shelf and place it on a stable table, then pour the water sample into the separating funnel to allow the phytoplankton to settle naturally. After 48 hours, use a small glass tube (diameter less than 2mm) to slowly absorb the phytoplankton by siphon method. Absorb the upper clear night carefully, and then put the precipitate into the reagent bottle. Since the supernatant must be sucked off manually when the separatory funnel separates liquid, a little carelessness will sti...
