The utility model is achieved through the following technical solutions:
A kind of manual simplified Suction filtration device, it is characterized in that: comprise a hollow vessel, this hollow vessel upper end is provided with a seal cover, hollow vessel inner edge below sealing lid is closely embedded with a piston that can pump along hollow vessel inner edge, a pull bar is shaped with in this piston upper surface, this pull bar upper end is stretched out by described seal cover, form a cavity between described piston lower surface and hollow vessel bottom surface, in the sidewall of the hollow vessel of described cavity both sides, be shaped with the air inlet and gas outlet that are connected with the external world respectively.
And, be respectively shaped with the link of organizing phase contraposition in described seal cover lower surface and the upper surface of described piston more, in two links of often group phase contraposition, mount the both side ends of a rubber rubber band respectively.
And the upper end of described pull bar is shaped with one handle, the pull bar length between this handle to piston upper surface is slightly larger than the vertical height of described hollow vessel.
And, be shaped with the appendix be connected with gas outlet with described air inlet outside described hollow vessel respectively, in described two appendixs, be shaped with valve respectively.
Another object of the present utility model is to set up a kind of manual simplified suction filtration system, it is characterized in that: comprise a kind of manual simplified Suction filtration device of multiple stage, wherein the air inlet of the manual simplified Suction filtration device of First is connected with needing the exhaust outlet of Suction filtration device by appendix, the gas outlet of the manual simplified Suction filtration device of described First is communicated with in turn by the air inlet of the manual simplified Suction filtration device of appendix and next, is all shaped with described valve in every root appendix.
Advantage of the present utility model and good effect are:
In the utility model, hollow vessel fitting piston, air inlet and gas outlet, by the reciprocating motion of pull bar in seal cover, can change the volume in cavity and then the air pressure in continuous change hollow vessel progressively, thus reach the object of continuous suction filtration gas; The mounting means of the link compound rubber rubber band made in seal cover lower surface and piston upper surface is simple, and is convenient to user's push-and-pull piston, makes it easy to use; The appendix made outside hollow vessel coordinates valve Suction filtration device can be carried out the use that temporary transient opening and closing of fault facilitates Suction filtration device; The manual simplified Suction filtration device of described multiple stage matches and the gas volume difference of suction filtration required in experiment can be adjusted, and makes suction filtration system meet the needs of experiment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Structural representation when Fig. 2 is the utility model use.
Detailed description of the invention
Elaborate to the utility model below by embodiment, described embodiment is illustrative, and nonrestrictive, can not limit protection domain of the present utility model with this.
A kind of manual simplified Suction filtration device, the utility model innovation is, comprise a hollow vessel 4, this hollow vessel upper end is provided with a seal cover 3, hollow vessel inner edge below sealing lid is closely embedded with a piston 7 that can pump along hollow vessel inner edge, a pull bar 2 is shaped with in this piston upper surface, this pull bar upper end is stretched out by described seal cover, form a cavity 12 between described piston lower surface and hollow vessel bottom surface 11, in the sidewall of the hollow vessel of described cavity both sides, be shaped with the air inlet 13 be connected with the external world and gas outlet 10 respectively.Be shaped with the appendix 9 be connected with gas outlet with described air inlet outside described hollow vessel respectively, in described two appendixs, be shaped with valve 8 respectively.
The present embodiment, for the ease of the push-and-pull of piston, is respectively shaped with the link 6 of organizing phase contraposition in described seal cover lower surface and the upper surface of described piston more, mounts the both side ends of a rubber rubber band 5 in two links of often group phase contraposition respectively.The upper end of described pull bar is shaped with one handle 1, and the pull bar length between this handle to piston upper surface is slightly larger than the vertical height of described hollow vessel.
In the utility model, except the structure described in above-described embodiment, also can adopt the structure shown in embodiment 2, another object of the present utility model is to set up a kind of manual simplified suction filtration system, the utility model innovation is, comprise a kind of manual simplified Suction filtration device of multiple stage, wherein the air inlet of the manual simplified Suction filtration device of First is connected with needing the exhaust outlet of Suction filtration device by appendix, the gas outlet of the manual simplified Suction filtration device of described First is communicated with in turn by the air inlet of the manual simplified Suction filtration device of appendix and next, described valve is all shaped with in every root appendix.
