Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Fig. 2 show structural schematic diagram of the invention.
The present invention provides a kind of railway freight-car whirler-type dust catcher devices, including dust arrester upper housing 1, tubular dust filtering
Shell 4 and dust-collecting box 6 in net 2, dust arrester.
Inlet chamber and outlet chamber are provided on the dust arrester upper housing 1, outlet chamber center is higher than inlet chamber center；It is described
Inlet chamber and outlet chamber end are equipped with DN25 flange.
1 bottom of dust arrester upper housing connect to form dust-collecting cavity with shell 4 in dust arrester, and dust-collecting box 6 is mounted on dust
4 bottom of shell in device.
Plummer 10 is equipped in the dust-collecting cavity, tubular dirt filtrating screen 2 is mounted in dust-collecting cavity by plummer 10, inlet chamber
The wind blown over drives tubular dirt filtrating screen 2 to rotate by tubular dirt filtrating screen 2, and large grained impurity is fallen directly into the dust-collecting box 6 of lower section,
Under the blowing of wind, a part is fallen in inside tubular dirt filtrating screen 2 fine granularity impurity, and a part centrifugation impinges upon shell in dust arrester
On 4 inner wall of body, it is finally collected in dust-collecting box 6.
1 inner wall of dust arrester upper housing is up-narrow and down-wide stairstepping, and upper inside wall width is less than tubular dirt filtrating screen 2
Outer diameter, the factors such as blow-back, which can be effectively prevented, causes impurity accidentally to pass through, and enters in brake branch pipe.
Fig. 3 a-e show the structural schematic diagram of dirt filtrating screen of the present invention.
The tubular dirt filtrating screen 2 is sintered with the metal material of certain filtering accuracy, and structure becomes a common practice colyliform, is increased
The area of 2 filtering surface of tubular dirt filtrating screen, wind wheel shape can guarantee that, when high pressure blows air over, tubular dirt filtrating screen 2 can revolve simultaneously
It rotates into and reaches centrifugal effect.
The plummer 10 is the stair-stepping cylindrical body being made of upper plummer and lower plummer.
The bottom of the dust-collecting box 6 is equipped with scupper, which is blocked by screw plug 7, can be right by opening screw plug 7
Dust arrester is checked and is drained the sundries inside dust arrester, and when maintenance, which to dust arrester can not tear open greatly, unloads greatly, maintenance process
It is convenient.
O-shaped rubber seal 1 is equipped in the dust arrester upper housing 1 and dust arrester between shell 4, passes through 8 He of bolt
Nut 9 connects；O-shaped rubber seal 25 is equipped in the dust arrester between shell 4 and dust-collecting box 6.
The assembling spacing of the inlet chamber and the DN25 flange of outlet chamber end is 241mm, and two chamber height spacing are 30mm,
It is completely the same, it can be achieved that interchange with Combined dust collector.
The working principle of the invention and the course of work:
The wind blown over from brake pipe passes through dirt filtrating screen, and tubular dirt filtrating screen 2 is driven to rotate, and large grained impurity is made in centrifugation
It can be impinged upon on the inner wall of dust collector body, be fallen directly into the dust-collecting box 6 of lower section, fine granularity impurity is blown high-pressure blast with lower
Under, a part of impurity can be fallen in the cylindrical body inside tubular dirt filtrating screen 2 by the outside of tubular dirt filtrating screen 2, since tubular is filtered
Dirt net 2 constantly rotates, and falls after hitting 2 inner wall of tubular dirt filtrating screen into the impurity inside tubular dirt filtrating screen, is finally collected in collection
In dirt box, another part impurity is impinged upon under the action of the centrifugal in dust collecting body, is finally collected in dust-collecting box 6, only smaller
The impurity of particle can just be entered in brake branch pipe by whirler-type dust catcher, and the whirler-type dust catcher of the invention can mention significantly
The filtering accuracy of high dust arrester, and manufacturing process is relatively easy.
The present invention improves the filter effect of dust arrester, prevents impurity from entering inside brake valve by pipeline, reduces system
Move the generation of bad caused traffic safety accident；Increase scupper, facilitate and exclude the water and sundries collected in dust arrester,
It is convenient and efficient, the repair time is reduced, manpower is saved, improves efficiency.
The embodiment above of the present invention, is merely illustrative, be not it is only, it is all within the scope of the present invention or it is equivalent this
Change in the range of invention is surrounded by the present invention.
