Description
Technical field
The utility model relates to a kind of mechanical device of clean air, especially a kind of engineering machinery engine air inlet prefilter.
Background technique
Motor is the heart of internal-combustion engine, and air filter is the lung of motor.The air sucking in engine working process directly has influence on the performance of the duty of engine, the stability of work, reliability, the feature of environmental protection, even greatly affects the life-span of motor.Statistics shows, premature wear, the cigarette of motor are large, oil consumption is high, the fault such as unable, and most situations are relevant with air inlet quality, and proportion is more than 85%.Conventionally, diesel machine air inlet quality is better, and intake resistance is less, and whole gas handling system performance just can be better, and engine performance is also better.At present, along with the development with rapid changepl. never-ending changes and improvements of motor new technology, air-strainer technology is also constantly weeded out the old and bring forth the new, and meets the demand of different phase motor.Air-strainer technology has successively experienced early stage oil bath type and oil immersed type filter cleaner, develops into clean, efficient paper filter core formula air filter now; In addition, from single-stage filter, develop into the multistage filter cleaner with several functions.
Therefore engineering machinery vehicle is operation in desert, mine conventionally, and working environment is extremely severe, and in air, dust granules thing is more, need to more clean, air filter system efficiently.Thereby reduce the generation of the faults such as motor premature wear, improve the working efficiency of motor and engineering machinery vehicle.Air filter system mainly comprises prefilter and air filter two-part efficiently at present.Air filter is generally paper filter core formula structure, prefilter is cyclone type coarse filter structure, its groundwork principle is: inlet stream enters in prefilter High Rotation Speed under the effect of blade becomes High Rotation Speed air-flow, the High Rotation Speed air stream that is being mingled with dust granules separates dust granules and air under the effect of centrifugal force, dust granules is discharged from special relief opening, more clean air after being filtered.Cyclone type coarse filter is adapted at the engineering machinery vehicle of operation under general environment operating mode, for the vehicle in the lower operation of high dust atmosphere (particularly desert area), this cyclone type coarse filter far from meets the demands, and needs the prefilter that development efficiency is higher, intake resistance is less.
Air-strainer: be mainly used in the fields such as pneumatic machinery, diesel machine, effect is to provide clean air for these machinery, in case these machinery suck the probability that increases wearing and tearing with the air of impurity particle and damage at work.The chief component of air-strainer is filter core and casing, and wherein filter core is main filtration fraction, and casing is that the external structure of necessary protection is provided for filter core.
Prefilter: as the term suggests be a kind of mechanical device of clean air in advance; be that air is before entering air-strainer; first the air with impurity is tentatively filtered; object is to remove larger particulate matter; the air that makes to enter air-strainer is relatively clean; to reach protection air cleaner cartridge, improve the object of filter efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of engineering machinery engine air inlet prefilter, solves the defect that original prefilter filter efficiency is low, air quality is poor.
The purpose of this utility model realizes as follows: have a prefilter housing, rotor at prefilter housing inner top device with some blades, in prefilter housing upper side, be provided with dust-discharging mouth, in prefilter housing, bottom sets out airduct, annular space envelope between the end opening of prefilter housing and air outlet tube periphery has air inlet screen, some swirl vanes are set in prefilter housing above air inlet screen, separately there is a connecting cylinder, connecting cylinder upper end is connected with air outlet tube, in connecting cylinder end opening endoporus, stretch into the inner core of a undergauge, between inner core end opening limit and connecting cylinder inner hole wall, shutoff has flange plate, lower dust-discharging mouth is set on connecting cylinder lower sides.
Swirl vane is connected on air outlet tube periphery wall and is integrally formed structure.
During work, air is inhaled in prefilter by air inlet screen, removes the particulate matter that particle diameter is greater than opening of sieve when by air inlet screen, this single filter that is prefilter.Air stream enters in prefilter housing High Rotation Speed under the guiding function of swirl vane, forms High Rotation Speed air stream, and under the effect of centrifugal force, particulate matter and air separation that quality is larger come, and to inner walls, move.Granule dust thing is thrown out of housing by the upper dust-discharging mouth of slit on prefilter housing under the effect of rotor.Air after clean is being rotated down and is entering in connecting cylinder by air outlet tube by the rotation blade of rotor, and high-speed air flow continues rotation and moves down in connecting cylinder.Under the effect of centrifugal force, particulate matter outwards moves and drops on flange plate with the collision of connecting cylinder inwall, and the air stream that the dust granules dropping is rotated by lower dust-discharging mouth is discharged.Relatively clean air is entered in engine air filter and is again filtered by inner core, finally enters in motor.
The utility model filter efficiency is high, and air quality is high; Reduce to change air cleaner cartridge probability, improve air filter working life; Engine charge quality is high, reduces motor infant mortality, improves service life of aeroengine; Simple in structure, compact, be convenient to produce and install; Intake resistance is little, and transmitter air inlet is many; Low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, there is a prefilter housing 5, rotor 3 at prefilter housing 5 inner top devices with some blades, in prefilter housing 5 upper side, be provided with dust-discharging mouth 4, in the interior bottom of prefilter housing 5, set out airduct, annular space envelope between the end opening of prefilter housing 5 and air outlet tube periphery has air inlet screen 1, some swirl vanes 2 are set in prefilter housing 5 above air inlet screen 1, swirl vane 2 is connected on air outlet tube periphery wall and becomes one structure, separately there is a connecting cylinder 6, connecting cylinder 6 upper ends are connected with air outlet tube, in connecting cylinder 6 end opening endoporus, stretch into the inner core 9 of a undergauge, between inner core 9 end opening limits and connecting cylinder 6 inner hole walls, shutoff has flange plate 8, lower dust-discharging mouth 7 is set on connecting cylinder 6 lower sides.With the air stream of granule dust through in the process of this prefilter, granule dust respectively air inlet screen 1, on dust-discharging mouth 4 and 7 three places, lower dust-discharging mouth be removed with air separation, thereby clean the air that enters motor.During use, this prefilter is fixed on above air filter, air filter connecting engine suction port.Under motor getter action, the air stream that is mingled with dust granules is inhaled in prefilter, and air stream is cleaned after prefilter and air filter successively, and the air after cleaning enters motor.
