At present, mainly there is following defect in the selection evaporimeter that domestic and international laboratory generally adopts: must dismantle distilling flask when (1) charging and cleaning and just can complete, labour intensity is large; (2) accurately charging automatically can not be realized, need manually to add charging.
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned deficiency, provides a kind of Rotary Evaporators of accurate charging.
The utility model is achieved through the following technical solutions: a kind of Rotary Evaporators of accurate charging, comprises support, distilling flask, condenser, heated water bath and receiving bottle, distilling flask is rack-mount, the bottom of distilling flask is heated water bath, distilling flask is communicated with condenser by glass bushing, the bottom of condenser is connected with receiving bottle, it is characterized in that: described distilling flask top is provided with charging aperture, and described charging aperture is provided with accurate feed arrangement, described accurate feed arrangement comprises stepper motor, large belt wheel, small pulley, driving-belt, ball screw, feed screw nut, feeding cylinder, slide block, charging plug, feed nozzle, described motor is equipped with large belt wheel on exporting, described large belt wheel is connected with small pulley by driving-belt, described small pulley is arranged on ball screw upper end, described ball screw is equipped with feed screw nut, and described feed screw nut is fixed on slide block, and described slide block becomes to be slidably connected with feeding cylinder, charging plug is equipped with in described ball screw lower end, and described feeding cylinder bottom is provided with feed nozzle.
Further, described distilling flask bottom is provided with discharging opening.
The utility model has following advantage:
(1) charging aperture of the present utility model is provided with accurate feed arrangement, accurate automatic feed, automatic gauge can be realized, ensure to need the solution of distillation and concentration to enter distilling flask in strict accordance with the volume or weight of setting, both can ensure the quality of distilling, the security operated can be ensured again.
(2) the utility model is provided with charging aperture and discharging opening, charging is very convenient with cleaning, simple to operate, need the solution of distillation and concentration can enter distilling flask by the charging aperture being located at distilling flask top, be distilled after concentrating and can flow out flask by the discharging opening of bottom, do not need dismounting distilling flask to come charging and discharging, decrease wearing and tearing or the damage of glassware, extend the service life of equipment glass apparatus, thus reduce equipment cost, facilitate the maintenance maintenance of equipment.When needing cleaning, as long as pour clear water from charging aperture, the sewage after cleaning can be discharged from discharging opening, very convenient.
