Description

Automatic siphon enrichment device for algae Technical Field The invention relates to the technical field of biological sample enrichment devices, in particular to an automatic siphon enrichment device for algae. Background Algae are key food sources for aquatic animals, release oxygen through photosynthesis to maintain water ecology, but excessive propagation can cause water bloom. The traditional algae quantitative observation needs to be sampled and fixed, then laboratory sedimentation and concentration are carried out, and supernatant is removed by artificial siphoning. Concentration and enrichment of an algae water sample are key pretreatment steps for monitoring the water environment. The traditional method completely relies on manual operation, namely pouring the fixed water sample into a separating funnel for standing, and then siphoning by manually pinching a rubber tube to remove the supernatant. The method has low efficiency and high operation strength, is influenced by personnel experience, has poor consistency of the concentrated volume, and is difficult to meet the requirements of mass and standardized detection. In order to improve efficiency, some improvements of automation or semi-automation have been presented in the prior art. One of the main ideas is to use an electric pump (such as a diaphragm pump and a peristaltic pump) as a power source, and establish and maintain siphoning through the pumping action of the pump. The automatic siphon device driven by the pump reduces the operation burden to a certain extent by replacing manual suction, and can realize the program control of the process by timing or a flowmeter. However, the existing automatic siphon device driven by the pump has the following problems that 1. The cost and the complexity are high, the whole system must comprise a pump body, a motor, a power supply module and a corresponding control circuit, the structure is complex, and the manufacturing cost and the maintenance cost of the whole machine are obviously increased. 2. The electric pump works independently of the power supply depending on a stable power source, which limits the application of the electric pump in the field, vehicle-mounted or power unstable environment. 3. Vibration and noise are introduced, namely mechanical vibration generated during the operation of the pump body is transmitted to the sample container through the bracket, the potential risk of disturbing sediment exists, and meanwhile, the working noise is unfavorable for a quiet experimental environment. 4. There is a maintenance need for pumps as moving parts, wear, aging problems, long term reliability challenges, and siphon failure due to pump pipe fatigue, valve leaks, etc. Disclosure of Invention The invention aims to solve the defects in the prior art and provides an automatic siphon enrichment device for algae.
