Abstract
The utility model relates to the technical field of filter, especially a kind of use for laboratory filter, comprise beaker, the openend of beaker is provided with sealing-plug, be equipped with towards the conduction stick in beaker in sealing-plug, conduction stick be provided with the funnel communicated with it, in funnel, be provided with filter paper, the cup of beaker is connected with flexible pipe with it, and the other end of flexible pipe is connected with the inflator communicated with beaker inner chamber.This use for laboratory filter, good filtration effect, suction continues, can automatic air-exchanging, and suction is easy to operate greatly.
Description
Technical field
The utility model relates to the technical field of filter, especially a kind of use for laboratory filter.
Background technology
As shown in Figure 1, in the science classroom in junior middle school, typical filter method carries out solid, liquid separation, its concrete steps are: first filter paper is converted into taper shape, then the filter paper rolled well is placed in funnel, adding distil water is fitted by filter paper and leakage half, is finally poured in filter tunnel by glass bar drainage by the suspensions such as muddy water.
Although this experimental provision operates very simple and convenient, filter process is more time-consuming, and teacher, when class demonstration, often wastes time, and affects teaching process.In order to accelerate the rate of filtration, often conventional reduced pressure filtration method, filtration under diminished pressure needs vacuum air pump to bleed, but vacuum air pump price is high, and equipment is heavier, not easily moves classroom to and uses.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem proposed in above-mentioned background technology, and the utility model provides a kind of use for laboratory filter, good filtration effect, and suction can continue, and meeting automatic air-exchanging, suction is easy to operate greatly.
The utility model solves the technical scheme that its technical problem adopts: a kind of use for laboratory filter, comprise beaker, the openend of beaker is provided with sealing-plug, be equipped with towards the conduction stick in beaker in sealing-plug, conduction stick is provided with the funnel communicated with it, be provided with filter paper in funnel, the cup of beaker is connected with flexible pipe with it, and the other end of flexible pipe is connected with the inflator communicated with beaker inner chamber.
Further restriction: inflator is manual pump.
Further restriction: be arranged at the shape of the filter paper in funnel for conical.
The beneficial effects of the utility model: this use for laboratory filter, the filtration under diminished pressure mode utilizing dual-purpose inflator to bleed, it is high that dual-purpose inflator filtration is suitable for suction requirement, the mixture that the rate of filtration is slow, can promote the use of as science classroom experiment, suction can continue, and meeting automatic air-exchanging, suction is easy to operate greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of existing filtration experiment device;
Fig. 2 is structural representation of the present utility model.
In figure: 1, beaker, 2, sealing-plug, 3, conduction stick, 4, funnel, 5, filter paper, 6, flexible pipe, 7, inflator.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Use for laboratory filter as shown in Figure 2, comprise beaker 1, the openend of beaker 1 is provided with sealing-plug 2, be equipped with towards the conduction stick 3 in beaker 1 in sealing-plug 2, conduction stick 3 is provided with the funnel 4 communicated with it, be provided with filter paper 5 in funnel 4, the cup of beaker 1 is connected with flexible pipe 6 with it, and the other end of flexible pipe 6 is connected with the inflator 7 with beaker 1 inner chamber phase.
Wherein inflator 7 is manual pump.Be arranged at the shape of the filter paper 5 in funnel 1 for conical.
This use for laboratory filter, utilizes the filtration under diminished pressure mode that dual-purpose inflator 7 is bled, and it is high that dual-purpose inflator 7 filtration is suitable for suction requirement, the mixture that the rate of filtration is slow, can promote the use of as science classroom experiment, and suction can continue, meeting automatic air-exchanging, suction is easy to operate greatly.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
