Description
Technical field
The present invention relates to locomotive aeration technology field.
Background technology
The equipment room of electric locomotive is provided with many electrical equipments, and electrical equipment work sends substantial amounts of heat, a part
Electric equipment, such as traction electric machine, heat is discharged to outside car by forced ventilation, during another part is then delivered between locomotive equipment,
When especially summer environment temperature is higher, temperature is up to 60 DEG C in equipment room.So necessary ventilation must be carried out to equipment room
Radiating.Again due in order to ensure the cleaning of equipment room and internal electric equipment, preventing dust from entering, must in equipment room this
A certain degree of malleation is maintained in the space of opposing seal.This requires the clean air of suction sufficient amount in equipment room, one
Divide outside discharge car and take away the heat of equipment room, a part stays in the in-car a certain degree of malleation of in-car maintenance.And between inhalation device
The clean-up performance of interior air directly affects the service life of in-car electrical equipment.Therefore the air sucked in equipment room must be entered
The filtering of row enough accuracy.
The electrical equipment for either needing forced ventilation to cool down, it is desired nonetheless to the electrical equipment of heat transfer free convection, all need
Cooling air is wanted there are higher cleannes.Ventilating system is required for installing necessary filter, and what filter filtered out
Dust dirt must periodic cleaning just can guarantee that playing a role in filtering long-term effectively for filter.
Divulged information in the prior art between electric locomotive equipment common two ways, one kind is directly sucked in sky for ventilation blower outside car
Gas is directly entered in-car after being filtered, another kind is that ventilation blower is that in-car bypasses when needing the equipment of forced air cooling to cool down
A part of filtered air is into the car.
Although air outside car can be blown into equipment room after filtering and be cooled down by the equipment room draft type of prior art,
But for filter through long-term work, its dust deposit is more and more, causes filter resistance increasing.It has impact on entering for equipment room
Wind flow.At this moment timely cleaning replacement filter is just needed.And some filters are at locomotive header inclined-plane, change relatively tired
It is difficult.Substantially increase maintenance cost and maintenance time.
The content of the invention
It is good and be not required to the filter element of frequent clean that technical problem solved by the invention is to provide a kind of strainability
The automatic dust discharge ventilating system of locomotive malleation.
The technical solution adopted by the present invention is the automatic dust discharge ventilating system of locomotive malleation, including ventilation blower, cyclonic filter
Air through coarse filtration outside car is blowed to cyclone filter by device, ventilating duct and dust-exhausting port, ventilation blower, cyclone filter include outer barrel and
Inner cylinder, outer barrel top are provided with rotary accelerator, and inner cylinder inlet end is located at outer barrel afterbody, and inner cylinder outlet side is communicated in ventilating duct,
Ventilating duct conveys cooling air to electrical equipment or equipment room, is laying dust chamber between inner cylinder and outer barrel, laying dust chamber is connected with dust discharge
Mouthful, the dust-exhausting port connection car external space.
Inner cylinder flare, tail end are flared end.
Inner cylinder with outer barrel is concentric installs.
The invention has the advantages that safeguard a kind of malleation that is more difficult and inventing for equipment room ventilation system filter
The ventilating system of automatic dust discharge maintenance-free type.The ventilating system can by the air pressure difference outside filter interior and car incited somebody to action
Dust and rainwater in filter are automatically drained out outside car.Remain the cleaning in filter.And filter can be remained
Resistance it is constant, enter without because filter resistance increase and influence the charge flow rate of equipment room.It can protect in positive equipment room
Constant air mass flow.
Brief description of the drawings
Fig. 1 is the ventilation system setups schematic diagram of the present invention.
Fig. 2 is filter fundamental diagram.
In figure mark for：1- cyclone filters, 2- dust-exhausting ports, 3- rotary accelerators, 4- inner cylinders, 5- outer barrels, 6- laying dust chambers,
7- ventilating ducts.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the automatic dust discharge ventilating system of locomotive malleation of the invention includes ventilation blower, cyclone filter
Air through coarse filtration outside car is blowed to cyclone filter 1 by the 1st, ventilating duct 7 and dust-exhausting port 2, ventilation blower, and cyclone filter 1 is the bitubular
Structure, outer barrel 5 are inlet cylinder, and inner cylinder 4 is aiutage, and the top of outer barrel 4 is provided with rotary accelerator 3, and the inlet end of inner cylinder 5 is positioned at outer
4 afterbodys of cylinder, the outlet side of inner cylinder 5 are communicated in ventilating duct 7, and ventilating duct 7 conveys cooling air, inner cylinder 5 to electrical equipment or equipment room
It is laying dust chamber 6 between outer barrel 4, cooling air is after ventilation blower pressurizes, and the rotating vane of rotated accelerator rotates at a high speed, ash
Dust-shower water etc. is rotated under the influence of centrifugal force compared with heavy substance by high speed, can be flowed into along the outer wall of outer barrel 5 in laying dust chamber 6.
The cooling air of cleaning enters lower ventilating duct 7 after cyclone filter, and a part needs forced air cooling for in-car
Electrical equipment (traction electric machine) cooled down, be partly into equipment room.Such as Fig. 2, and the dust filtered out through cyclone cylinder is deposited
Stay in filter laying dust chamber 6, because the inner air pressure of cyclone filter laying dust chamber 6 is much larger than atmospheric pressure outside car, therefore will rotation
The laying dust chamber 6 of wind filter 1 installs a dust-exhausting port 2 additional and is connected to by soft air duct and come round outside car, realizes the automatic dust discharge of malleation
Function.
Dust in cyclone cylinder is as partial air is outside the discharge car of dust-exhausting port 2.So filter both can be by air height
Precision is filtered, and the dust that can also be will filter out is discharged outside car by external and internal pressure difference.The automatic dust discharge of malleation is played, filter is exempted from
The effect of maintenance.
The filtering air cleanliness of the present invention is high.Ventilation blower directly blows to air cyclone filter 1, is rotated through cyclone cylinder
Most dusts, can be collected into laying dust chamber 6, pass through malleation by the high speed rotation of accelerator 3 by the effect of centrifugal force
Dust-exhausting port 2 is discharged outside car；Filter is non-maintaining, and due to use malleation dust discharge mode, dust can be automatically drained out in filter, be not required to
Manual cleaning, drastically increase service efficiency；Drainage effect is good.Rainwater enters cyclone filter 1 with air, through centrifugation at a high speed
Rotation is equally collected into laying dust chamber 6.Discharged by malleation dust-exhausting port 2 outside car.Rainwater deposition is avoided to flow into in-car；Use the longevity
Life length.As a result of the automatic dust discharge mode of malleation, free from dust residual in cyclone cylinder filter, filter will not because of blocking shadow
Ring its service life.Dirt can be discharged at any time in laying dust chamber 6, therefore filter can realize maintenance-free, dirt with
When discharge, therefore filtering accuracy will not be reduced due to the deposition of dust, and lifelong filtering accuracy does not change.
