Example Embodiment

[0068] Example 1

[0069] see figure 1 As shown in the figure, the multi-rotating axis evaporator that can accurately and quantitatively concentrate multiple samples at one time according to this embodiment includes: a bracket 1, on which a rotary motor 2 is fixed, and the rotary motor 2 drives two The retort on the axis of rotation 171, 172 rotates (the rotary evaporator of the present invention is also provided with a control panel and components for controlling the rotation speed and heating temperature of the rotating motor, which are not shown in the figure), and the rotation can be unidirectional or unidirectional. The two directions are alternately carried out, and the rotation of the two rotation axes 171 and 172 by the rotating motor 2 can be completed by the crawler, chain or gear in the transmission body 3;

[0070] The two rotation axes 171, 172 have a downward inclination angle with the horizontal plane, which is 15 degrees;

[0071] One end of the transmission ...

Example Embodiment

[0101] Example 2

[0102] like figure 2 As shown, the difference from Example 1 is that the evaporated gas in the 4 distillation flasks first passes through the respective steam pipes, then passes through the respective condenser pipes, and then enters the common 1 condenser 5 after passing through the condenser pipe header. Condensation, collected in 1 collector 6.

Example Embodiment

[0103] Example 3

[0104] Different from Example 1, the number of distillation flasks included in the distillation flask group may be 2 or 3 or 5 or more.

Abstract

The invention relates to the technical field of chemical experiment equipment, in particular to a rotary evaporator, and particularly relates to a multi-rotating-shaft evaporator capable of accuratelyand quantitatively concentrating a plurality of samples in one time. The invention discloses a multi-rotating-shaft evaporator capable of accurately and quantitatively concentrating a plurality of samples at a time. One rotating shaft of an original rotary evaporator is increased to at least two rotating shafts. A declination included angle (a certain degree between 2 and 44 degrees) is formed between each rotating shaft and the horizontal plane; each rotating shaft is provided with one or more distillation flasks which are sequentially connected in series; a raw water (oil) bath pan is changed into an electric heating belt; an opening is formed in the lowest liquid level of the working position of each distillation flask and is connected with a concentrated solution gate bin with a concentrated solution quantifying and discharging function; the upper portion and the lower portion of the bin are each provided with a valve, the middle of the bin is provided with a scale metering pipe,distillation is stopped immediately when the amount of the concentrated solution reaches the designed accurate amount, the two valves are matched to be opened and closed, and accurate and quantitativedischarging of all the concentrated solutions can be achieved on the premise that a distillation flask does not need to be detached and negative pressure in a system is not greatly affected.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a rotary evaporator, in particular to a multi-rotary shaft evaporator capable of accurately quantitatively concentrating multiple samples at one time. Background technique [0002] Rotary evaporator is an extraction experimental equipment for vacuum distillation and concentration of materials. It is widely used in experiments such as large-scale concentration, drying, extraction and recovery of samples, especially for rapid distillation of large amounts of solvents. Existing rotary evaporators are usually composed of vacuum pumping devices, heating devices, condensing devices, rotating devices and other components. The principle of rotary evaporators is mainly controlled by electronic equipment, so that the flask rotates at a constant speed at the most suitable speed to form a thin film of solvent , increase the evaporation area, and use a vacuum pump to mak...
