Specific embodiment
Hereinafter embodiments of the present invention are illustrated by particular specific embodiment, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
It should be clear that structure depicted in this specification institute accompanying drawings, ratio, size etc., all only in order to coordinate specification to be taken off
The content shown, so that those skilled in the art understands and reads, is not limited to the enforceable qualifications of the present invention, therefore
Do not have technical essential meaning, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting the present invention
Under the effect that can be generated by and the purpose that can reach, all should still fall and obtain, in disclosed technology contents, the model that can cover
In enclosing.Meanwhile, in this specification cited as " on ", D score, "left", "right", " middle " and " one " etc. term, be also only
Be easy to describe understands, and is not used to limit the enforceable scope of the present invention, being altered or modified, no substantive of its relativeness
Under change technology contents, when being also considered as the enforceable category of the present invention.
As depicted in figs. 1 and 2, the rotary evaporator of the present invention, including water-bath 2, evaporative flask 1 and top-pushing mechanism 3, evaporates
Bottle 1 is located in water-bath 2, and the bottleneck of evaporative flask 1 is connected with the receiving flask 5 outside water-bath 2, in evaporative flask 1 by pipeline 4
Article are pipelined to after being subject to thermal response collect in receiving flask 5.The bottom of bottle of evaporative flask 1 is adsorbed with sucker 9, and sucker 9 passes through
Rotating shaft 6 is connected with the motor 7 outside water-bath 2, and motor 7 runs and drives evaporative flask 1 to rotate, thermally equivalent.Top-pushing mechanism 3 is by water
The top of bath 2 is stretched into and is pushed down evaporative flask 1 in water-bath 2 so that amplitude of fluctuation in rotation process for the evaporative flask 1 is limited
System, can also adjust evaporative flask 1 by top-pushing mechanism 3 simultaneously and be immersed into the depth in water.
As depicted in figs. 1 and 2, top-pushing mechanism 3 is cylinder, and the outer wall of evaporative flask 1 is circumferentially with cannelure 11, cylinder along it
Piston rod be located in cannelure 11, and push down evaporative flask 1, when evaporative flask 1 rotates, piston rod is always positioned in cannelure 11,
It is less that the position that evaporative flask 1 is in water makes it swing by the resistance at water source, and piston is passed through at evaporative flask 1 position above
Bar carries out spacing its amplitude of fluctuation of reduction so that stable the carrying out of evaporative flask 1 rotates.
As depicted in figs. 1 and 2, water-bath 2 includes pot 22 and pot cover 21, and pot 22 and pot cover 21 connect.Wherein, pot
22 and pot cover 21 both sides pass through buckle 8 clamping, using buckle 8 snap fit, so that pot cover 21 and pot 22 are completely de-
From, easy to disassemble cleaning and install evaporative flask 1, simultaneously dismount and mount dress also quick and convenient.Pot 22 and pot cover 21 can also be using another
A kind of mode connects, and the side of pot 22 is connected with pot cover 21 by hinge, and the opposite side of pot 22 passes through buckle and pot cover
21 clampings, so that pot cover 21 was both easy to open carries out laying evaporative flask by the way of this being partially broken away from, avoid pot simultaneously again
Lid 21 is departed from pot 22 to be lost, and operates also very convenient.For the ease of pipe laying 4 and rotating shaft 6, pot 22 top
Both sides are provided with fluting 221, and pipeline 4 is connected with receiving flask 5 after passing through one of fluting 221, and rotating shaft 6 passes through another to slot
It is connected with motor 7 after 221.Setting fluting 221 1 aspects are easily installed rotating shaft 6 and pipeline 4, on the other hand can also carry out air pressure
Discharge, it is to avoid the air pressure within water-bath 2 is too high to have an accident, pipeline 4 and rotating shaft 6 can move up and down along fluting 221, from
And adjust the contact depth of evaporative flask 1 and water source in pot 22.Because pipeline 4 and rotating shaft 6 can reduce open through fluting 221
The area of giving vent to anger of groove 221, thus it is too fast to avoid the thermal source in water-bath 2 to leak, improves reaction efficiency.Pot cover 21 is provided with note
The mouth of a river 211, can evaporate situation according to water source and select to increase at any time water source, easy to operate, it is to avoid impact reaction efficiency.
Present configuration is simple, simple to operation, and compact layout and structure rationally, is coordinated by top-pushing mechanism 3 and sucker 9
Improve evaporative flask 1 and rotate the stability run, setting fluting 221 carries out pipe laying 4 and rotates 6, promoting the circulation of qi pressure of going forward side by side simultaneously
Put, improve reaction efficiency, decrease the wasting of resources.
Above-described embodiment only principle of the illustrative present invention and its effect, not for the restriction present invention.Any ripe
The personage knowing this technology all can carry out modifications and changes without prejudice under the spirit and the scope of the present invention to above-described embodiment.Cause
This, those of ordinary skill in the art is complete with institute under technological thought without departing from disclosed spirit such as
All equivalent modifications becoming or change, must be covered by the claim of the present invention.
