Abstract
The present invention discloses a pump-free suction filtration apparatus, which comprises a funnel suction filtration container for holding a liquid to be subjected to suction filtration, and a gas storage container for storing Co2 gas, wherein the funnel suction filtration container and the gas storage container are connected through a pipeline, and the pipeline is provided with a water stopping clip. The pump-free suction filtration apparatus of the present invention has characteristics of simple structure, simple operation and low cost, and is suitable for teaching experiments in schools.
Description
Technical field
The invention belongs to suction filtration technical field, particularly relate to a kind of without pump Suction filtration device.
Background technology
Suction filtration device is used for the object reaching Separation of Solid and Liquid in an experiment.
Traditional Suction filtration device adopts vavuum pump usually, and vavuum pump price is not low, and operation is more complicated, is not adapted at applying in education experiment.
Summary of the invention
Based on this, for above-mentioned technical problem, provide a kind of visible spectrophotometer.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of without pump Suction filtration device, it is characterized in that, comprising for holding the funnel suction filtration container for the treatment of suction filtration liquid and for storing Co
2the air container of gas, described funnel suction filtration container is connected by pipeline with described air container, and this pipeline is provided with tongs.
This programme also comprises for the syringe to described air container injection sodium hydroxide solution.
Described air container is two, and both are connected with the pipeline of described funnel suction filtration container by a T-shaped pipe, and be connected with a rubber tube between this pipeline and described T-shaped pipe, described tongs is located on described rubber tube.
Described syringe is two.
Described funnel suction filtration container is 500ML sand core funnel bottle,suction, and described air container is that 500ML tool props up conical flask, and bottleneck is provided with rubber stopper, and described syringe is 10ML syringe.
Structure of the present invention and operation are all very simple, with low cost, are adapted at using in the education experiment of school.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of without pump Suction filtration device, comprise for holding the funnel suction filtration container 11 for the treatment of suction filtration liquid 2 and for storing Co
2the air container 12 of gas.
Funnel suction filtration container 11 is connected by pipeline 13 with air container 12, and this pipeline 13 is provided with tongs 14.
Before suction filtration, first inject in funnel suction filtration container 11 and treat suction filtration liquid 2, in air container 12, store Co in advance
2gas, then to hydrogen injecting sodium hydroxide solution in air container 12, now, Co
2gas and sodium hydroxide solution react, Co
2gas is absorbed in a large number, forms negative pressure, so just can carry out suction filtration in air container 12.
Open tongs 14 during suction filtration, make funnel suction filtration container 11 and air container 12 form path, because air container 12 inside has been negative pressure state, in funnel suction filtration container 11, treat suction filtration liquid 2 due to the effect of negative pressure by suction filtration.The present invention instead of costliness and the vavuum pump of relative complicated operation with simple equipment with reagent, can obtain relatively good suction filtration effect, facilitates student and teacher under the cost of relative moderate, realize suction filtration operation, is adapted at using in education experiment.
For the ease of to hydrogen injecting sodium hydroxide solution in air container 12, the present invention also can be equipped with syringe 15, for injecting sodium hydroxide solution.
Preferably, air container 12 is two, can improve its negative pressure ability, and both are connected by the pipeline 13 of a T-shaped pipe 16 with funnel suction filtration container 11, and be connected with a rubber tube 17 between this pipeline and T-shaped pipe 16, tongs 14 is located on rubber tube 17.
Accordingly, syringe 15 also can be two, with corresponding two air container 12.
Particularly, funnel suction filtration container 11 is 500ML sand core funnel bottle,suction, and air container 12 props up conical flask for 500ML tool, and bottleneck is provided with rubber stopper 18, and can insert for syringe 15, syringe 15 is 10ML syringe.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
