Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a rotary evaporator. Background Art

[0002] Rotary evaporator, also known as rotary evaporator, is a commonly used laboratory equipment, mainly used for continuous distillation of volatile solvents under reduced pressure conditions. It consists of a motor, distillation flask, heating pot, condenser and other parts, and is widely used in chemistry, chemical industry, biomedicine and other fields.

[0003] The Chinese utility model patent with application number CN201920583012.X in the prior art involves a rotary evaporator, including a water bath, a protective cover, a control center, a drive device, a collection component, etc., which can reduce the evaporation rate of water in the water bath, maintain the heat in the water bath, and improve efficiency.

[0004] However, in actual use, the above device needs to monitor the water level in the pot manually, which increases the labor intensity of the operator. At the same time, it is impossible to control the depth position of the distillation device in the pot and adjust the working efficiency of the distillation device. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a rotary evaporator which maintains water temperature through a water storage device and reduces impurities in the water source, monitors and controls the water level in the water storage device through a control device, improves the automation degree of the device and reduces the labor intensity of operators, adjusts the production efficiency of the equipment by adjusting the adjustment device, and improves the practicality of the device.

[0006] The utility model discloses a rotary evaporator, comprising a water storage device, a control device and an adjusting device, wherein the control device is mounted on the water storage device and the adjusting device is located on the upper side of the water storage device; the water temperature is maintained by the water storage device and impurities in the water source are reduced; the water level in the water storage device is monitored and controlled by the control device, the automation degree of the device is improved and the labor intensity of operators is reduced; the production efficiency of the equipment is adjusted by adjusting the adjusting device, and the practicability of the device is improved.

[0007] Preferably, the water storage device includes a heating base, a heating pot, a water pump and a filter. The heating pot is installed on the upper end surface of the heating base, the output end of the water pump is connected to the interior of the heating pot, and the filter is installed on the input end of the water pump. The water source is filtered by the filter to reduce impurities entering the interior of the heating pot, reduce the labor intensity of the operator during the cleaning of the heating pot, and heat the water in the heating pot by the heating base.

[0008] Preferably, the control device includes a mounting plate, a limit rod, a connecting rod, a pressure plate, a first pressure switch and a float. Two sets of mounting plates are horizontally mounted on the side of the heating pot through a bracket. The limit rod and the connecting rod both pass through the lower mounting plate. The upper end surface of the limit rod is connected to the upper mounting plate. The lower part of the connecting rod is connected to a float. The lower part of the limit rod passes through the float. The float can move on the limit rod. The upper end surface of the connecting rod is connected to a pressure plate, and the lower end surface of the lower mounting plate is installed with a first pressure switch. The float floats in the water in the heating pot. When the water level drops, the pressure plate drops with the float until the lower end surface of the pressure plate presses down on the first pressure switch. The first pressure switch controls the water pump to start and input water into the heating pot, thereby realizing the ability of automatic water addition. The lifting and lowering process of the float is limited by the limit rod, thereby improving the practicability of the device.

[0009] Preferably, it also includes a second pressure switch, which is installed on the upper end surface of the pressure plate; when the pressure plate rises with the water level until the upper end surface of the pressure plate contacts the lower end surface of the upper mounting plate, the pressure plate and the upper mounting plate squeeze the second pressure switch, and the second pressure switch controls the water pump to shut down, thereby stopping the addition of water to the heating pot, thereby improving the degree of automation of the device.

[0010] Preferably, the adjusting device includes an electric cylinder, a limit frame, a rotating shaft seat, a first bearing and a gooseneck bottle. The electric cylinder is vertically installed on the right side of the heating pot. The movable end of the electric cylinder is connected to the limit frame through the rotating shaft seat. The long neck part of the gooseneck bottle is connected to the limit frame through the first bearing. The body of the gooseneck bottle is located on the upper part of the heating pot. The limit frame provides support for the gooseneck bottle, and the first bearing enables the gooseneck bottle to rotate on the limit frame. The height of the gooseneck bottle body in the heating pot is controlled by controlling the elongation of the electric cylinder, thereby controlling the heating efficiency and reaction efficiency.

[0011] Preferably, it also includes a gantry, a second bearing, a reducer and a motor. The gantry is installed on the right side of the electric cylinder, and the reducer is installed on the inner middle part of the gantry through two groups of second bearings. The bottleneck end of the gooseneck bottle is connected to the output end of the reducer, and the motor is installed on the reducer. The two groups of second bearings enable the reducer to have the ability to rotate, which is convenient for cooperating with the limit frame device to control the inclination angle of the gooseneck bottle. When the motor is turned on, the power is transmitted to the gooseneck bottle through the reducer to drive the gooseneck bottle to rotate, so that the medicine in the bottle body of the gooseneck bottle is continuously shaken, thereby improving the production efficiency of the device.

[0012] Compared with the prior art, the beneficial effects of the utility model are: maintaining water temperature and reducing impurities in the water source through the water storage device, monitoring and controlling the water level in the water storage device through the control device, improving the degree of automation of the device and reducing the labor intensity of the operator, and adjusting the production efficiency of the equipment by adjusting the regulating device, thereby improving the practicability of the device.
