Abstract
The utility model belongs to vacuum pump technology field, specially a kind of buffer container for laboratory vacuum drying.Including bottle, bottle stopper and the first vacuum tube and the second vacuum tube；Bottle stopper is closed together in the bottleneck of bottle, and two perforates are set on bottle stopper；One end of first vacuum tube and the second vacuum tube is inserted through perforate respectively, and the other end connects vavuum pump and baking oven respectively.The utility model is simple in construction, easy to use, vavuum pump can be prevented to be pumped into dirt at work, serves buffering and contains the effect for taking liquid, equivalent to a safety can or container, avoids vavuum pump from damaging.
Description
Technical field
The utility model belongs to vacuum pump technology field, and in particular to a kind of buffering for laboratory vacuum drying is held
Device.
Background technology
Do in the lab in some operations with dehydration, it is necessary to some samples are dehydrated, general use
Baking oven heating, drying is dehydrated, and oven space is vacuumized, and can be improved drying efficiency, be reached more preferable dehydrating effect.
But when being vacuumized using vavuum pump to baking oven, the partial moisture of sample can be pumped into vavuum pump together, so as to
Influence the work of vavuum pump, or even damage vavuum pump.
The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, and cost is low, laboratory vacuum pump safe to use
Vacuum buffer triangular vessel.
Buffer container provided by the utility model for laboratory vacuum drying, including bottle 1, bottle stopper 2 and first
The vacuum tube 4 of vacuum tube 3 and second；
The bottle stopper 2 is closed together in the bottleneck of bottle 1, and two perforates are set on bottle stopper 2；First vacuum tube 3 and second
One end of vacuum tube 4 is inserted through perforate respectively, and the air entry of the other end connection vavuum pump of the first vacuum tube 3, second is true
The other end connection baking oven of blank pipe 4.
In the utility model, the bottom of bottle 1 is provided with the sewage draining exit of discharge waste liquid, is connected with blow-off pipe, blow-off pipe
It is provided with a switch valve 5.
In the utility model, the first vacuum tube 3 and the second vacuum tube 4 are the same as being provided with rubber seal between bottle stopper 2.
The utility model discharges air in baking oven in use, vavuum pump start-up operation, while baking oven heating sample；This
When, the partial moisture of sample can suck bottle by vavuum pump and deposit in bottom of bottle, and so as to be inhaled into vavuum pump, damage is set
It is standby.And when waste water is collected together a certain amount of, switch valve is opened, discharges waste water, continues vacuum pumping.
The utility model is simple in construction, easy to use, vavuum pump can be prevented to be pumped into dirt at work, serve buffering and
The effect for taking liquid is contained, equivalent to a safety can or container, avoids vavuum pump from damaging.
Brief description of the drawings
Fig. 1 is the utility model structural diagrams.
Label in figure：1 is bottle, and 2 be bottle stopper, and 3 be the first vacuum tube, and 4 be the second vacuum tube, and 5 be switch valve.
Embodiment
Buffer container provided by the utility model for laboratory vacuum drying, including bottle 1, bottle stopper 2 and first
The vacuum tube 4 of vacuum tube 3 and second；Bottle 1 uses Erlenmeyer flask.
The bottle stopper 2 is closed together in the bottleneck of triangular flask 1, and two perforates are set on bottle stopper 2；First vacuum tube 3 and
One end of two vacuum tubes 4 is inserted through perforate respectively, and the other end of the first vacuum tube 3 connects vavuum pump, the second vacuum tube 4
The other end connects baking oven.First vacuum tube 3 and the second vacuum tube 4 are the same as being provided with rubber seal between bottle stopper 2.
The bottom of bottle 1 is provided with the sewage draining exit of discharge waste liquid, is connected with blow-off pipe, and blow-off pipe is provided with a switch valve
5。
The utility model discharges air in baking oven in use, vavuum pump start-up operation, while baking oven heating sample；This
When, the partial moisture of sample can suck bottle by vavuum pump and deposit in bottom of bottle, and so as to be inhaled into vavuum pump, damage is set
