Description

TECHNICAL FIELD

[0001] The utility model relates to a siphon device, concretely relates to a siphon device for algae precipitation and concentration. BACKGROUND

[0002] In the quantitative analysis of phytoplankton, the water sample is put into a precipitation bottle for 24-36 hours of precipitation, and then the supernatant liquid without algae is carefully drawn out by a siphon tube to concentrate the sample to 30-50ml. In this process, the traditional siphon tube is usually replaced by a 2mm diameter medical infusion tube. However, a negative pressure needs to be applied to the infusion tube during siphoning. The method is usually to insert one end of the infusion tube into the liquid surface of the precipitation bottle, connect the other end to an ear bulb to suck the solution into the infusion tube to form a negative pressure in the infusion tube, and then siphon. This method is often complicated, and once the siphoning fails, a part of the water sample sucked into the infusion tube will flow back into the precipitation bottle. The water flow will stir the already precipitated sample, resulting in failure of the algae sample precipitation and concentration, and re-precipitation is required, which is time-consuming and laborious. SUMMARY

[0005] Preferably, a cork is arranged at the top end of the plankton precipitation bottle, two through holes are formed in the cork, the tube is inserted into one of the through holes, the tube can be conveniently moved up and down, the position of the trumpet mouth can be adjusted, the liquid in the plankton precipitation bottle can be sucked, and the other through hole is used for connecting the plankton precipitation bottle with the outside world to stabilize the air pressure in the plankton precipitation bottle.

[0006] Compared with the prior art, the utility model has the following advantages:

[0007] 1. The utility model discloses a water storage bottle's drainage forms the negative pressure in siphon pipe, need not use the ear syringe, effectively avoided because siphon process in siphon pipe loses the risk of negative pressure and makes siphon pipe liquid backflow destroys the sample, and siphon process is more convenient and efficient, and can control siphon process's progress through flow controller, adjusts the drainage flow of water storage bottle, and the operability is stronger.

[0008] 2. The utility model discloses a trumpet mouth is provided with plankton net on the bottom end of the intubation tube, increase the siphon area of plankton net and sample, can effectively avoid the siphon failure caused by the blockage of plankton or other impurities in plankton net mesh.

[0009] The utility model will be further explained in detail in combination with the drawings and examples. DRAWINGS

[0016] In order to make the above -mentioned purpose, feature and advantage of the utility model more obvious and easy to understand, the specific implementation of the utility model is explained in detail in combination with the drawings. In the following description, a lot of specific details are set forth to facilitate a full understanding of the utility model. But the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar improvements without violating the connotation of the utility model, therefore the utility model is not limited to the following disclosed specific implementation.

[0017] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation.
