Background
The rotary evaporator is mainly used for concentrating, crystallizing, drying, separating and recovering solvent in the industries of medicine, chemical industry, biological pharmacy and the like. The principle is that under the vacuum condition, the constant temperature heating is carried out, so that the rotary bottle rotates at a constant speed, and the materials form a large-area film on the wall of the bottle, thereby evaporating efficiently. The rotary evaporator is generally to place the evaporation flask in high-temperature water of a water bath, allow the evaporation flask to rotate at a constant speed, and heat the test solution in the evaporation flask at a constant temperature by passing through the high-temperature water in the water bath. However, the water bath of the traditional rotary evaporator is in an open state, after long-time heating, the evaporation speed of water in the water bath is also accelerated due to the continuous high temperature of the water body in the water bath heating process, so that the water in the water bath can be easily evaporated, continuous water adding of operators is needed, otherwise, the protection of the water bath is caused, and the water bath is protected by the ultra Wen Guandian, and the water temperature is required to be waited to rise to the water bath temperature when the water bath is brought to the operators for secondary water adding for heating, so that the test efficiency is low. Meanwhile, the open design of the water bath kettle also causes the energy consumption of the water bath kettle to be overlarge, and the production cost is increased.
For such a situation, patent with the publication number CN210186463U discloses a rotary evaporator, in which the water supply device includes a water source, a water supply pipe and a water pump, the water source is used for providing water, one end of the water supply pipe is connected with the water source, the other end of the water supply pipe passes through the water inlet, and the water pump is electrically connected with the control center and is used for pumping water in the water source into the water bath. In this patent, prior to use, a test solution is placed in an evaporation flask and a water pump pumps water from a water source through a water line into a water bath. When the water bath kettle is used, the control center controls water in the water bath kettle to heat, then the protective cover seals the water bath kettle, and meanwhile, the rotary driving assembly controls the evaporation flask to rotate. The evaporated test liquid is sent to the collecting assembly through the rotary driving assembly to be collected, if the water in the water bath kettle is evaporated, the control center can control the water pump to pump the water in the water source into the water bath kettle, so that the evaporating flask can continuously be heated to evaporate the test liquid. The water bath is sealed to the safety cover so that the evaporation rate of water in the water bath is reduced, and meanwhile, the heat provided by the water bath can be kept, and the test liquid in the evaporation flask is evaporated, so that the test efficiency is improved. When the water in the water bath can not provide the heat of the evaporating flask, the water in the water source can be pumped into the water bath by the control center control water pump, so that the water adding efficiency is improved, and the testing efficiency is further improved. Although this patent realizes the isolation closure of water-bath through the safety cover, but because the continuous heating of water-bath can make the water evaporate continuously, and the temperature of safety cover can be necessarily lower than the temperature of water-bath, consequently can lead to the steam condensation of evaporation to be on the safety cover, can influence the observation of operating personnel to the evaporation liquid in water-bath and the evaporation flask like this.
