Abstract
A water-saving power-saving suction filter is formed by a Buchner funnel, a rubber plug, a suction flask, a conduit, a valve core, an injector, a unidirectional valve film, a rubber band and a plastic pipe seat component with a handle. The Buchner funnel is plugged in the suction flask through the rubber plug. The valve core is connected with the injector through the conduit. An injector piston is provided with the unidirectional valve film. An injector cylinder is provided with the rubber band used to tense the injector piston. The whole suction filter is installed on the plastic pipe seat with the handle. An operation of the filter is simple. Water saving, power saving and time saving effects are remarkable. The filter is suitable for junior high school and high school chemistry demonstration experiments, a grouping experiment and a primary school nature science experiment.
Description
Technical field
The utility model relates to a kind of teaching aid of the usefulness of imparting knowledge to students, particularly a kind of water saving power saving nutsch filter.
Background technology
Filtration in the existing textbook chemistry teaching: 1. common filtration, 2. tap water suction filtration, 3. vacuum pump suction filtration, weak point: 1. time-consuming, 2. the classroom is without tap water, and consumes a large amount of water, 3. expensive, heavy, the power consumption of vacuum pump.
Summary of the invention
The purpose of this utility model provides a kind of water saving power saving nutsch filter, described nutsch filter, and simple to operate, demonstrative process is obvious, and intuitive is strong.
The utility model achieves the above object by the following technical programs: a kind of water saving power saving nutsch filter is provided, is made of Buchner funnel, plug, bottle,suction, conduit, valve inside, syringe, one-way cock film, bungee and band handle plastics base parts.
Described Buchner funnel by the plug plug on bottle,suction, valve inside is connected with syringe by conduit, syringe piston is provided with the one-way cock film, and syringe cylinder is provided with the bungee for the tension syringe piston, and whole nutsch filter is installed on the plastics base with handle.
Characteristics of the present utility model are:
1, adopt syringe to bleed.
2, utilize piston retaining valve and the exhaust of bungee pulling force.
3, utilize valve inside to make non-return valve, prevent that air from entering bottle,suction.
Description of drawings
Fig. 1 is the structural representation of water saving power saving nutsch filter described in the utility model.
Embodiment
Below by drawings and Examples the technical solution of the utility model is described further.
Contrast Fig. 1, water saving power saving nutsch filter described in the utility model is assembled by transparent plastic Buchner funnel 1, plug 2, transparent plastic bottle,suction 3, plastic catheter 4, valve inside 5,50mm plastic injector 6, one-way cock film 7, bungee 8 and band handle plastics base 9.
Described transparent plastic Buchner funnel 1 is filled on transparent plastic bottle,suction 3 by plug 2, valve inside 5 is connected with 50mm plastic injector 6 by plastic catheter 4, syringe piston is provided with one-way cock film 7, the cylinder of 50mm plastic injector 6 is provided with the bungee 8 of tension syringe piston, and whole suction filtration system is installed on the plastics base 9 with handle.
The using method of described water saving power saving nutsch filter:
1. the filter paper of suitable size on the note in the transparent plastic Buchner funnel is poured precipitation mixture into, holds the nutsch filter handle, draw most syringe piston to bleed with forefinger, middle finger, unclamp finger, piston is retracted the piston exhaust by bungee, repeatedly, namely clean the liquid suction filtration in the precipitation mixture.
The utility model is applicable to junior middle school, senior chemistry lecture experiment and grouping experiment and primary school nature scientific experiment.
The utility model advantage: simple to operate, the water saving power saving saves time, and phenomenon is obvious, and is safe and reliable.
