Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:
With reference to Fig. 1 and Fig. 2, the defecator of a kind of negative pressure equipment described in the present embodiment, including filtrate housing 1 and filtering bodies 2.Outlet 11 and import 12 it is provided with in this filtrate housing 1.Filtrate housing 1 inner hollow is arranged, so that filtrate housing 1 has been internally formed filter chamber.Described outlet 11 and import 12 all run through with filter chamber.Described filtering bodies 2 is installed in filter chamber.Described filtrate housing 1 includes the first shell 13 and the second housing 14 removably connected with the first shell 13.Offer outlet 11 on described first shell 13, described second housing 14 offers import 12.Certainly, it is possible on described first shell 13, offer import 12, described second housing 14 offers outlet 11.The first cavity 130 is offered on described first shell 13.The second cavity 140 is offered on second housing 14.Described first shell 13 can fit together into a generally assembled state with second housing 14；Also can mutually take apart.When taking apart, the environment of the part within filtrate housing 1 and inside can be carried out.It is under assembled state at described first shell 13 with second housing 14, described first cavity 130 and the second cavity 140 is through is combined into described filter chamber.Can facilitate by the first shell 13 is connected removably with second housing 14 filtering bodies 2 in filtrate housing 1 and filter chamber internal medium are carried out.If during the overlong time that filtering bodies 2 uses, filtering bodies 2 can being cleaned in time or changes.
An airway 3 it is respectively fixed with at described outlet 11 and import 12.By airway 3, gas can be entered filter chamber by import 12, then by outlet 11 by the gas after filter chamber inner filtration from outlet 11 everywhere.
Described filtrate housing 1 is internal is fixed with fixing post 15 and column sleeve 16.Described fixing post 15 and column sleeve 16 can be separately positioned on the first shell 13 and second housing 14.Hole 160, location is offered on described column sleeve 16.Each fixing post 15 can be respectively interposed in a described column sleeve 16.Such as: be provided with fixing post 15 on described first shell 13, second housing 14 is provided with column sleeve 16；Or it is provided with fixing post 15 on described second housing body 14, the first shell 13 is provided with column sleeve 16；Or on the first shell 13, it is simultaneously installed with described fixing post 15 and column sleeve 16, the corresponding column sleeve of installation 16 also corresponding on second housing 14 and fixing post 15.Being under assembled state at described first shell 13 and second housing 14, described fixing post 15 is interspersed in the hole, location 160 of column sleeve 16.Described fixing post 15 is respectively positioned in described filter chamber with column sleeve 16.Hole, described location 160 is offered along the axis direction of column sleeve 16, and runs through the end face being suspended in filter chamber, so that hole 160, location is also mutually communicated with filter chamber.
As preferred embodiment, positioning filtering bodies 2 for convenience, it is ensured that the effect of filtration is the best, described filtering bodies 2 is positioned at the space that fixing post 15 encloses with column sleeve 16.Described filtering bodies 2 can be sponge.Due to the breathing freely of sponge, gas-flow resistance is low, performance of ventilating good, moreover it is possible to absorbs aqueous vapor, and avoids the advantages such as large granular impurity passes.
The locating dowel 17 into filtering bodies 2 location it is separately provided on described first shell 13 and/or second housing 14.Described locating dowel 17 is positioned at filter chamber.Described locating dowel 17 is for positioning filtering bodies 2, in order to preferably filtering bodies 2 can be filtered the gas in filter chamber.The first shell 13 or second housing 14 are fixed in one end of each locating dowel 17, and the other end is suspended in filter chamber.The external diameter of each locating dowel 17 is pointed to by the first shell 13 or second housing 14 and successively decreases successively on the direction of filter chamber center.So so that the end that each locating dowel 17 is suspended in filter chamber is tip, in order to simpler through filtering bodies 2, more easily filtering bodies 2 is positioned.
Preferably, the defecator of this negative pressure equipment may also include sealing ring 4.It is under assembled state at described first shell 13 and second housing 14.Described sealing ring 4 is fixed on the junction between the first shell 13 and second housing 14.This sealing ring 4 is for cramming the gap between the first shell 13 and second housing 14, in order to seal filter chamber, improves the efficiency of negative pressure equipment work.
In sum, the defecator of negative pressure equipment of the present utility model, the first shell 13 and second housing 14 can be dismantled and connect, so can effectively the filtering bodies 2 in defecator and filter chamber internal medium be carried out.Additionally in the built-in filtering bodies of filter chamber 2, when gas is entered by import 12, can be filtered body 2 and granule foreign is filtered, be then passed through exporting 11 through negative pressure equipment.The most described filtering bodies 2 can be effectively prevented from impurity and enter in negative pressure equipment, and filtering bodies 2 can also adsorb the aqueous vapor in air, it is to avoid aqueous vapor enters negative pressure equipment and damages negative pressure equipment.Additionally the gas-flow resistance of filtering bodies 2 is low, performance of ventilating good.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and within all these changes and deformation all should belong to this utility model scope of the claims.
