AI Technical Summary
Technical Problem
When the existing rotary evaporator is used, the water in the water bath will gradually decrease. If water is not added in time, the rotary bottle will not be heated, affecting the working efficiency.
Method used
A petroleum ether reflux dehydration device is designed, which includes a water injection assembly, which automatically controls the replenishment and stop of water through the cooperation of a float ball and a connecting rod to ensure that there is always enough water in the water bath.
Benefits of technology
It realizes that the rotary evaporator can be heated for a long time without manual water addition, improves working efficiency and avoids the problem of equipment not being able to operate normally due to insufficient water.

Abstract
The utility model relates to the technical field of petroleum ether reflux dehydration, and discloses a petroleum ether reflux dehydration device which comprises a mounting seat, a rotary evaporator is fixed at the top of the mounting seat, a water bath kettle is fixed at the top of the mounting seat, a water injection assembly is arranged on the surfaces of the mounting seat and the water bath kettle, and the water injection assembly comprises a water tank, a water inlet pipe and a water outlet pipe, according to the petroleum ether reflux dehydration device, a water injection assembly and a floating ball descend, a linkage rod rotates anticlockwise, a second fixed rod drives a movable rod and a rubber plug to ascend, at the moment, the rubber plug does not block a water outlet of a connecting pipe any more, manual water adding is not needed, and the problems that a rotary bottle cannot be heated due to the fact that water is not added in time, and long-term heating cannot be achieved can be avoided; when the water flow is attached to the surface of the floating ball, the floating ball gradually ascends to drive the linkage rod to rotate clockwise with the first fixed rod as the fulcrum, at the moment, the second fixed rod drives the movable rod and the rubber plug to move downwards, and the water flow does not continue to conduct water injection work any more.
