Problems solved by technology
The cooling water used by the rotary evaporator is only used for heat exchange and is not polluted, and it is directly discharged into the sewer, causing great waste
The main reason for this phenomenon is that the cooling water circulation devices on the market are all equipped with cooling devices for return water, which require a relatively independent cooling system. The equipment is relatively complicated, and the price is thousands or even tens of thousands of yuan.
However, for a general laboratory rotary evaporator, its value is only a few thousand yuan.
Therefore, considering the short-term cost, it is not cost-effective to purchase a cooling water circulation device on the market for this device, so the current situation is caused

The invention provides a simple water circulating apparatus matched with a laboratory rotary evaporator. The simple water circulating apparatus comprises a reflux pipe, a hanging rod buckle, a hanging rod, a thermometer probe, a reflux water buffer tank, a temperature display device, a transformer, a speed regulator, a water pump, a water outlet pipe, a water storage tank and a filtration head, wherein water is condensed through the reflux pipe, and is recovered and input into the reflux water buffer tank from the rotary evaporator, water in the water storage tank is input into the rotary evaporator through the water outlet pipe, and a water circulating system is formed through work of the water pump. According to the present invention, a position of the reflux water buffer tank in the water storage tank is adjusted to dynamically and real-timely determine a reflux water temperature so as to meet experimental requirements. The simple water circulating apparatus has characteristics of rational design, low manufacturing cost, simple structure, easy use, easy application and promotion, and good cooling water recycling.
Description
technical field [0001] The invention belongs to a laboratory device, and relates to a simple water circulation device matched with a laboratory rotary evaporator, which is applied to a cooling water reflux reuse device when water or other liquids are used as coolants. Background technique [0002] Water is an important part of natural resources and the main material basis for the structural composition and life activities of all living things. From a global perspective, water is the link connecting all ecosystems. Natural ecosystems can not only control the flow of water, but also continuously promote the purification and circulation of water. Therefore, in the natural environment, water is of decisive significance for the survival of organisms and human beings. [0003] According to estimates by hydrogeographers, the total amount of water resources on the earth is about 1.38 billion cubic kilometers, of which 97.5% is seawater (1.345 billion cubic kilometers). Fresh water...
