Description

Vacuum generating device
Technical field
This utility model relates to a kind of train vacuum feces collecting device, and in particular, this utility model relates generally to a kind of vacuum generating device.
Background technology
Bullet train is limited by objective condition himself, basic employing vacuum feces collecting system is as toilet-flushing apparatus, and at present the vacuum generator in feces collecting system is with polyformaldehyde as material of main part on train, due to the build-in attribute of polyformaldehyde, in disassembly process, easily cause craze and transfiguration thus cause evacuation efficiency to decline and even completely lose function.Thus be necessary to study for the structure of this kind of vacuum generating device and improve.
Utility model content
One of the purpose of this utility model is for above-mentioned deficiency, it is provided that a kind of vacuum generating device, causes craze and transfiguration when solving vacuum generating device of the prior art dismounting with expectation, and the most therefore the efficiency affecting evacuation cause the technical problems such as afunction.
For solving above-mentioned technical problem, this utility model by the following technical solutions:
A kind of vacuum generating device provided by the utility model, described vacuum generating device includes upper end jet body, the top of described upper end jet body is provided with the first air inlet, bottom is provided with taper gas outlet, the bottom of described upper end jet body is also equipped with middle part diffuser casing, described taper gas outlet is placed in the inner chamber of middle part diffuser casing, it is additionally provided with the second air inlet and gas outlet on the diffuser casing of described middle part, described second air inlet, gas outlet all with the intracavity inter-connection of middle part diffuser casing, the bottom of described middle part diffuser casing is also equipped with lower end earial drainage device, described gas outlet is connected with lower end earial drainage device by diffuser pipe.
As preferably, further technical scheme is: described second air inlet is placed on the side of middle part diffuser casing, and is connected with negative pressure chamber.
Further technical scheme is: described upper end jet body, middle part diffuser casing are rustless steel with the material of lower end earial drainage device.
Compared with prior art, one of the beneficial effects of the utility model are: split type by being set to by vacuum generating device, can make to dismount more convenient, and are easy to maintenance, it is to avoid device causes in disassembly process damage, thus affects the effect of its evacuation;A kind of vacuum generating device simple in construction the most provided by the utility model, is suitable to industrialized production, it is easy to promote.
Accompanying drawing explanation
Fig. 1 is the structural representation for one embodiment of this utility model is described;
In figure, 1 be upper end jet body, 11 be the first air inlet, 12 be taper gas outlet, 2 be middle part diffuser casing, 21 be the second air inlet, 22 be gas outlet, 3 be lower end earial drainage device, 31 for diffuser pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further elaborated.
With reference to shown in Fig. 1, an embodiment of the present utility model is a kind of vacuum generating device, this vacuum generating device includes upper end jet body 1, the top of upper end jet body 1 is provided with the first air inlet 11, bottom is provided with taper gas outlet 12, and the bottom of aforementioned upper end jet body 1 is also equipped with middle part diffuser casing 2, taper gas outlet 12 is placed in the inner chamber of middle part diffuser casing 2, the second air inlet 21 and gas outlet 22 it is additionally provided with on aforementioned middle part diffuser casing 2, and make the second air inlet 21, gas outlet 22 all with the intracavity inter-connection of middle part diffuser casing 2, in addition, the bottom of middle part diffuser casing 2 also needs to install lower end earial drainage device 3, and be connected with lower end earial drainage device 3 by diffuser pipe 31 by gas outlet 22.Preferably, aforesaid upper end jet body 1, middle part diffuser casing 2 and lower end earial drainage device 3 all can use rustless steel to be processed into, and when 304 rustless steel main material, it is to avoid the problem of the craze and transfiguration appeared in environmental corrosion and dismounting operation process, it is ensured that the efficiency of evacuation.
In the present embodiment, the most split type by vacuum generating device is set to, device dismounting can be made more convenient, and be easy to maintenance, it is to avoid device be caused damage by disassembly process, thus affects the effect of its evacuation.
Again from reference to shown in Fig. 1, supporting the use for ease of the vacuum feces collecting system with train, aforesaid second air inlet 21 is preferably arranged on the side of middle part diffuser casing 2, thus can in use be connected with the negative pressure chamber in vacuum feces collecting system.
The above-mentioned preferred embodiment of this utility model is in actual use, compressed air is entered by first air inlet 11 on upper end jet body 1 top, flow velocity is accelerated under the effect of taper gas outlet, its underpart 12, utilize the viscosity of air, make to accelerate the compressed air after flow velocity through middle part diffuser casing 2 and entered during lower end earial drainage device 3 discharges by diffuser pipe 31, simultaneously by the second air inlet 21 being connected with negative pressure chamber, drive the air in negative pressure chamber to enter diffuser pipe 31 in the lump to be discharged by lower end earial drainage device 3, thus realize the vacuum action to negative pressure chamber.
Than that described above, it can further be stated that " embodiment ", " another embodiment ", " embodiment " spoken of in this manual etc., the specific features, structure or the feature that refer to combine the description of this embodiment are included at least one embodiment that the application generality describes.The most multiple local appearance statement of the same race is not necessarily to refer to same embodiment.Furthermore, it is understood that combine any embodiment when describing a specific features, structure or feature, to be advocated is to combine other embodiments also to fall in the range of this utility model to realize this feature, structure or feature.
This utility model is described by multiple explanatory embodiment the most of the present utility model, but, should be appreciated that, those skilled in the art can be designed that a lot of other amendments and embodiment, and these amendments and embodiment will fall within spirit disclosed in the present application and spirit.More specifically, in the range of disclosure, drawings and claims, the building block of theme composite configuration and/or layout can be carried out multiple modification and improvement.In addition to the modification carrying out building block and/or layout and improvement, to those skilled in the art, other purposes also will be apparent from.
