Abstract
Disclosed is an oil-bath air cleaner composed of a shell, an air inlet pipe, a vent-pipe, a barrier bar, trap valves and an oil sump. The utility model is mainly characterized in that a two-stage filter core whose two stages are inter-wound from metal wire trap valves with different mesh number is arranged inside the shell(1); the filter core is fixed inside an annular cavum which is provided with evenly distributed airways (10); a packing washer (8) is arranged around the barrier bar of the annular cavum; the mesh number and the meshes of the two-stage filter core are different in size; the mesh number of the trap valve of a first-stage filter core(6) is less than that of the second-stage trap valve while the mesh of the first-stage filter core is bigger than that of the second-stage trap valve. The utility model can filter the air two times with a filtering efficiency exceeding 99.75%, therefore the utility model is particularly suitable to be used on a truck to filter the dust inhaled in the motor in dusty area, desert, and dry area.
Description
Technical field: the utility model relates to motor car engine oil bath formula air-strainer
Improvement invention, particularly be filter screen order number in a kind of secondary filter core
The oil bath air cleaner all inequality with width of mesh.
Background technique: in the prior art, look into the vapour of China Patent No. 85203944
The car air-strainer is made up of shell and filter core, filter core frame and lower casing
Body looping chamber.There is a tangent exhaust outlet this chamber side, filter
Core is formed by the bulk coiling of thinner woven wire cloth, is placed on the filter core frame
In fixing, the filter core below is provided with an oil sump, filter cleaner adopts centrifugal branch
Carry out coarse filtration from the mode that the absorption with oil film combines, its structure is more multiple
Assorted, other looks into 98215724 utility model patents, discloses by the Ningbo City
The oil bath device of the oil bath air cleaner of Cai Kangcai application, this device
Major character be that one of suit is logical on the air intake pipe below the exhaust outlet
The style sheet is not opened in the exhaust outlet below ring arc area of this air grating sheet
Through hole, the chord length of ring arc area is greater than the diameter of exhaust outlet, and he solves
Under the relatively poor situation of road conditions, travel when Motor Vehicle, because of vehicle jolts,
Machine oil in the oil bath device rocks, because the ring arc area of ventilation catch
Stop, make machine oil can not enter the motor oil cylinder, cause motor to beat
Driving, this oil bath device also can only be applied to motor vehicle such as tractor
On, its adaptability can not satisfy existing motor vehicle air filtering far away
Need.
Summary of the invention: in view of the problem that known technology exists, the purpose of this utility model
Aim to provide a kind of wide adaptability, can with the sending out of multiple vehicle different capacity
Motivation coupling has simple in structurely, and filtering effect height can improve and start
The oil bath air cleaner in machine working life.The utility model be by as
Following mode is finished, whole air-strainer include housing, suction tude,
Barrier, filter screen, oil sump and outlet pipe, described suction tude is located at housing
The center portion, described outlet pipe is located at top one side of housing, and is described
Oil sump is located at lower part of frame, it is characterized in that being provided with in the housing two-stage by
The filter core that the different meshes braid fabric interweaves and reels and form, described two-stage
The order number of filter screen and varying in size of mesh in the filter core, described different meshes
The filter core that the coiling that interweaves forms is fixed on the annular with even cloth vent hole
In the cavity, and be provided with seal ring at the barrier periphery of toroidal cavity.Described
The housing of the barrier sealing part of one-level filter core and secondary filter core is provided with dress
Shackle, the order number of filter screen is less than in the secondary filter core and filters in the described one-level filter core
The order number of net, and the filter screen mesh in the one-level filter core is greater than in the secondary filter core
The mesh of filter screen.Oil bath according to the utility model design motif made
The formula air-strainer, through the coarse filtration of one-level filter core again through the secondary filter core
Smart filter, filtering efficiency can reach 99.75%, and can different merits with multiple vehicle
The Engine Matching of rate.Simple in structure, effect is obvious, with prior art
Compare and have substantial characteristics and progress.
Description of drawings: the utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 shows for the toroidal cavity with even cloth vent hole of the present utility model
Intention.
Specific embodiment: accompanying drawing has been represented structure of the present utility model and embodiment,
The relevant details that further describes embodiment below more in conjunction with the accompanying drawings reaches
Working principle.This oil-bath filter is installed in the motor car engine cylinder
Inlet.Described oil-bath filter includes housing 1, air inlet
9 are located at the center portion of housing 1, and described outlet pipe 2 is located at housing 1
One side on top, described oil sump 7 is located at the bottom of housing 1, described shell
Being provided with two-stage in the body 1 is interweaved with reeling by the different meshes wire and forms
Filter core, the size of the order number of filter screen and mesh is not in the described two-stage filter core
With.The order number of filter screen is less than filter screen in the secondary filter core 3 in the one-level filter core 6
The order number, and the filter screen mesh in the one-level filter core 6 is greater than secondary filter core 3
In the mesh of filter screen, form the coarse filtration of air, then many through the order number again
The filter core 3 that mesh is little carries out the essence filter.Described two-stage different meshes and mesh
Filter core be separately fixed in the toroidal cavity with even cloth vent hole, and
The housing of core sealing part is provided with loading and unloading and buckles 5.The seal ring at sealing place
8 can guarantee air past outlet pipe 2 discharges after coarse filtration and smart filter.Described housing 1 is by upper shell, and filter core annular chamber and oil sump 7 are assembled into one, and can load and unload, and have the gap between the barrier of the pasta of described oil sump 7 and one-level filter core toroidal cavity.
When the utility model work, be contained in the dust of the suction tude 9 of the oil bath air cleaner different mean particle dias of inspiration from air of motor car engine cylinder inlet, arrow is an air-flow direction among the figure, as not filtering, these air that have dust can be sent into motor, can cause the steam-cylinder piston premature wear of motor like this and life-span of reducing motor.Therefore, the thick dust that enters air directly is deposited in the oil sump 7, and thinner dust enters 6 filtrations of one-level filter core through the barrier of sparing the cloth vent hole, be that coarse filtration has hindered advancing of a part of particulate dust, the dust that will have a minute quantity mean particle dia enters second level filter core 3 in company with air and filters promptly smart filter, because the order number of braid fabric is numerous and mesh trickle, is enough to stop all dust to pass through, its filtering efficiency can be more than or equal to 99.75%, and oil shortage ratio is less than 0.0018g/m
3, and qualified by detecting, therefore can improve 1/3 of engine life, continue filtering through subsequent processing again through the air after the above two-stage filtering, its air purification degree has reached standard-required.Be specially adapted in the strong wind desert climate, the air filtering of the truck motor in dry area, and also the metal filtering core replacing is easily, and it is convenient to clean, and can use with the Engine Matching of multiple vehicle different capacity.
