Description

A kind of Simple decompression Suction filtration device
Technical field
The utility model belongs to equipment of chemical industry field, and in particular to a kind of Simple decompression Suction filtration device.
Background technology
Rural middle school some schools do not open up decompression and filter experiment at present, and main cause is no laboratory or do not filtered Experimental provision and auxiliary facility, the experiment can not be normally opened up, and there is auxiliary facility school to pass through pumping of drawing water with running water Gas, can not recycle running water, largely cause originally water waste.
Utility model content
The utility model provides a kind of Simple decompression Suction filtration device, to solve existing suction filtration experimental provision selling at exorbitant prices, The powerless purchase of rural school, running water suction pump pumping waste water resource the problem of.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of Simple decompression Suction filtration device, including funnel and bottle,suction, in addition to air extractor, air extractor include piston Pump, three-way pipe, pumping check valve and deflation check valve, the horizontal both ends of three-way pipe are single with the openend of piston pump and pumping respectively Connected to valve, the other end of three-way pipe sets deflation check valve, and pumping check valve one end and bottle,suction away from piston pump are taken out Gas port connects;Porous barrier is provided with funnel, the outside of funnel is provided with closure, and closure connects with the bottleneck of bottle,suction.
In order to further realize the utility model, the internal diameter of closure is adapted with the bottleneck external diameter of bottle,suction.
In order to further realize the utility model, closure is elaxtic seal.
In order to further realize the utility model, funnel and porous barrier are structure as a whole.
Connecting tube is provided with order to further realize the utility model, between each part of air extractor to connect.
The utility model has the beneficial effect that relative to existing experimental provision:
Design pumping check valve and deflation check valve, ensure to be opened and closed extraction gas, piston at any time in piston pump pumping process Pump continuous air extraction forms negative pressure, filters, will not be limited by laboratory equipment so as to complete decompression, without running water, realizes Using water wisely, reduces experimental cost, and pressure-reduction filter device of the present utility model is simple in construction, easy to operate, securely and reliably, Cost is low, saving water resource, can be widely popularized use, is advantageous to middle chemistry course and opens up decompression suction filtration experiment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Reference implication is as follows:1st, piston pump;2nd, three-way pipe;3rd, it is evacuated check valve;4th, deflation check valve;5th, filter Bottle;6th, bleeding point;7th, funnel;8th, porous barrier;9th, closure;10th, connecting tube;11st, piston rod.
Embodiment
The utility model is described further with reference to the accompanying drawings and detailed description.
A kind of Simple decompression Suction filtration device, including funnel 7 and bottle,suction 5, in addition to air extractor, air extractor include living Fill in pump 1, three-way pipe 2, pumping check valve 3 and deflation check valve 4, the horizontal both ends of three-way pipe 2 openend with piston pump 1 respectively Connected with pumping check valve 3, the other end of three-way pipe 2 sets deflation check valve 4, the one end of pumping check valve 3 away from piston pump 1 It is connected with the bleeding point 6 of bottle,suction 5, is connected between each part of air extractor provided with connecting tube 10;Porous barrier is provided with funnel 7 8, funnel 7 and porous barrier 8 are structure as a whole, and the outside of funnel 7 is provided with closure 9, the bottleneck phase of closure 9 and bottle,suction 5 Connect, the internal diameter of closure 9 is adapted with the bottleneck external diameter of bottle,suction 5, and closure 9 is elaxtic seal.
During suction filtration, the piston rod 11 of piston pump 1 is pulled out, generation negative pressure in connecting tube 10 is opened pumping check valve 3, will Gas in bottle,suction 5 is extracted, stopping action when piston rod 11 will be pulled away from piston pump 1, and the negative pressure in connecting tube 10 disappears Lose, pumping check valve 3 is closed, and piston rod 11 is pushed into piston pump 1, so as to which the gas in piston pump 1 is pushed into connecting tube In 10, because pumping check valve 3 is closed, then only deflation check valve 4 is opened under gas pressure effect, and by the He of piston pump 1 Gas discharge in connecting tube, gas pressure is disappeared when piston rod 11 is completely into 1 bottom of piston pump, and deflation check valve 4 is closed, The piston rod 11 of piston pump 1 is pulled out again, and repeat action above for several times, is made in bottle,suction by the continuous air extraction of piston pump 1 Gas is extracted to form negative pressure so as to reach the purpose of suction filtration.
