Description
Technical field
This patent is related to a kind of evaporator, more particularly to a kind of water-bath vibration that can handle multiple samples simultaneously is evaporated in vacuo
Device.
Background technology
Evaporator demand
Evaporation concentrator is that institute of testing laboratory is indispensable and most widely used common apparatus, food security, health,
There is extremely important effect in the detection such as environment, at present the product of the vacuum concentration of domestic and international Development and Production, its operation principle
To reduce sample solvent boiling point by vacuum, while shuttle is pivoted, and on the one hand makes sample thermally equivalent, on the other hand
By rotating the evaporation surface of increase liquid, its thickening efficiency depends on rotation, vacuum, heating technique combination.But due to by
Mechanically operated limitation, it is difficult to realize multiple samples and concentrates simultaneously.It can not meet that laboratory needs quickly handle the requirement of sample.
In order to realize sample batch concentration, solves the problems, such as multichannel evaporation, the product for having exploitation abandons container and revolved around axle
Turn, vacuum evaporation is carried out by way of carrying out partition heating to multichannel sample, but due to needing to being carried out per each passage
Zone temperature controls, system complex, and cost of implementation is high, and reduces the evaporation efficiency of single channel.
The present invention is based on coaxial Rotation Design, is not increasing system complexity, and do not reduce the condition of single channel evaporation efficiency
Under, realize that sample concentrates parallel；Using standard component interface, it is easy to expanded function, thickening efficiency significantly improves；In addition each passage is adopted
Effectively it can prevent sample room from polluting with independent control, above feature is particularly suitable for the requirement of laboratory sample batch processing.
The content of the invention
The invention provides it is a kind of integrate it is coaxial rotation concussion, vacuum, heating technique multi-channel parallel sample add
Fast evaporation concentrator, multiple samples can be handled simultaneously, and there is good autgmentability, be greatly improved sample concentration efficiency, extensively
It is applied to the field of sample concentration, such as food safety detection, environmental monitoring.
Technical solution of the present invention：By vacuum plant (1), centralized collection condenser (2), opening valve (3), relief valve (4), company
Connect flexible pipe (5), coaxial rotation rocking equipment (6), temperature control device (7), shuttle (8), shuttle interface (9) composition.Make
Sample to be concentrated is placed into shuttle (8) by the used time, is sealed by shuttle interface (9).Shuttle interface is set on (9)
Relief valve (4) and opening valve (3) are put, when relief valve (4) is opened, shuttle is connected with external environment, and holding reaches normal
Air pressure, it now can easily remove shuttle (8)：When closing relief valve (4) opening opening valve (3), shuttle (8)
It is connected by opening valve (3) with centralized collection condenser (2), centralized collection condenser (2) is used for the condensation of evaporation solvent and given up
Liquid reclaims.Vacuum plant (1) is used for providing negative pressure, reduces the boiling point of solvent, accelerates evaporation.Coaxial rotation oscillation device (6) can drive
Multiple shuttle (8) common rotations, fluid sample is rotated concussion in shuttle, accelerate evaporation.Temperature control device (7) is used
In temperature needed for holding solute evaporation.
The present invention has following technique effect compared with first technology：
1st, the present invention has the parallel concentrating function of multiple samples, improves sample concentration efficiency, solves sample batch concentration
It is required that.
2nd, individually control effectively prevents sample room from polluting to multichannel of the present invention.
3rd, temperature control uniformity, vacuum are consistent between each path of the present invention, and sample treatment uniformity is good,
4th, cost of the present invention is low, compact-sized, and occupancy laboratory area is few, easy to use, has a good application prospect.
The present invention can be used for food safety detection Pesticides, wild animal resources, environmental monitoring.

Deflated in vacuum sky flask (8).There is connection flexible pipe (5) on ground glass interface (9), pass through opening valve (3) and glass condenser
(2) it is connected, the opening and closing of opening valve (3) determines whether this road evaporator is connected to vacuum system.Evaporate and stop for each road sample
Time control can be used and automatically controlled by vacuum valve according to liquid evaporation amount or using manually control mode.Glass
Multiple interfaces are integrated with condenser, multichannel sample can be connected to by opening valve (3) respectively, condensation waste liquid carries out unified collection.
Glass condenser is connected to system with ＜ 20bar vavuum pumps (1) and provides negative pressure.It is all to be hung in rotation into the flask for having sample (8)
On rotary device (6), reciprocal circular motion is done in the horizontal plane with it, and drive fluid sample to be evaporated to be rotated in bottle,
Evaporation rate is improved, and prevents solution waterfall from splashing.All flasks (8) for filling sample, which are immersed in water bath (7), keeps suitable
Liquid evaporation temperature.
