Abstract
Diesel locomotive close-coupled inertia air filter of the invention, it is made up of inertia filter cylinder, casing and blower motor group, one dust discharge case is set, blower motor group is using outer rotor without spiral case centrifugal fan, it is installed in dust discharge case, laying dust area below inertia filter cylinder is connected by guide shell with the inlet scoop of the blower fan, and the dust-exhausting port of the dust discharge case leads to outside car.Simple structure, occupies little space, is easily installed, and maintains easily maintenance.
Description
Technical field
The present invention relates to a kind of diesel locomotive close-coupled air cleaner, belong to railway locomotive manufacturing technology field.
Background technology
A diesel locomotive typically point three-level is filtered to air：One-level is wavy metal net, filters the larger grains of sand；Two grades
It is inertia air filter, filters out the moisture and dust of the overwhelming majority；Three-level is the air refined filtration of paper filter element or other forms
Device.In the prior art, the inertia air filter that above-mentioned cascade filtration is used is generally power cleaning type, by inertia filter cylinder,
Casing, blower motor group, flexible pipe composition.Air sucks inertia filter cylinder from vent external, and the air after filtering is directly entered locomotive
Inside, and dust enters casing under the centrifugal action of inertia filter cylinder, converges in the laying dust area of bottom half.Blower motor group
Outside the enclosure is installed, inlet scoop is suctioned out laying dust by flexible pipe, and laying dust is discharged to vent external by exhaust outlet by another flexible pipe.This
Plant scheme blower motor group occupancy interior space larger, influence the mounting arrangements of other parts.Complex structure, installation steps are numerous
It is trivial, it is not easy to Maintenance and Repair.
The content of the invention
The purpose of the present invention is exactly the deficiency for overcoming above-mentioned prior art, there is provided a kind of diesel locomotive close-coupled inertia air
Filter.
The object of the present invention is achieved like this：A kind of diesel locomotive close-coupled inertia air filter, by inertia filter cylinder,
Casing and blower motor group are constituted, and the inertia filter cylinder is installed between two plates on casing top, it is characterised in that set in casing
A dust discharge case is put, blower motor group, without spiral case centrifugal fan, is installed in dust discharge case, below inertia filter cylinder using outer rotor
Laying dust area is connected by guide shell with the inlet scoop of the blower fan, and the dust-exhausting port of the dust discharge case leads to outside car.
Technical scheme, due to being provided with the dust discharge case of internal fan, simple structure is occupied little space, is easy to
Install, maintain easily maintenance.
Brief description of the drawings
Fig. 1 is the diesel locomotive close-coupled inertia air filter schematic elevation view of the embodiment of the present invention.
Fig. 2 is the schematic side view of Fig. 1.
Marked in figure：1- inertia filter cylinders, 2- casings, 3- blower motor groups, 4- dust discharge casees, 5- laying dusts area, 6- guide shells,
7- dust-exhausting ports.
Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Referring to accompanying drawing, the diesel locomotive close-coupled inertia air filter of the present embodiment, by inertia filter cylinder 1, casing 2, wind
Electromechanical unit 3 is constituted.To mitigate weight, casing 2 uses aluminium alloy structure, if being installed on vehicle body side wall by bolt stem.It is used
Property filter cylinder 1 was the functional part of air filtering, was installed between two plates on the top of casing 2.The bottom of casing sets a dust discharge case
4, blower motor group 3, without spiral case centrifugal fan, is installed in dust discharge case 4 using outer rotor by bolt, the lower section of inertia filter cylinder 1
Laying dust area 5 be connected with the inlet scoop of blower motor group 3 by guide shell 6, the dust-exhausting port 7 of dust discharge case 4 leads to outside car.
During work, wind is sucked from vent external, and intra-locomotive is directly entered by the air after the filtering of inertia filter cylinder 1, and
Dust then enters casing 2 under the centrifugal action of inertia filter cylinder 1, converges in laying dust area 5, and dust is by guide shell 6 by blower fan
The suction dust discharge of group of motors 3 case 4, vent external is discharged to by dust-exhausting port 7.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
Modified with to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
