Abstract
The utility model relates to an air filter for a medium-heavy cab-behind-engine truck, comprising a fine filter and a coarse filter connected with the fine filter into an integrated structure, wherein the air outlet of the coarse filter is communicated with the air inlet of the fine filter; the structure of the fine filter is basically the same as the existing structure; the coarse filter is mainly composed of two coarse filtering elements; each coarse filtering element comprises a coarse filter cartridge, a mesh enclosure, a blade ring arranged at the front end of the coarse filter cartridge, and a coarse filtering air outlet pipe arranged at the rear end of the coarse filter cartridge; the mesh enclosure is fixed to the front end port of the coarse filter cartridge; a coarse filter dust-discharge/water-drainage opening is formed on the downward side of the coarse filter cartridge; transverse separators are arranged on the front end and the rear end of each of the two coarse filter cartridges; and the two coarse filtering elements are connected in parallel to each other and connected to the housing of the fine filter through the transverse separators and a covering shell. The air filter for the medium-heavy cab-behind-engine truck, by employing an external-coarse filter manner, reduces the air ingoing resistance, and is high in filtering efficiency; and the service life of the air filter is prolonged; besides, the air flowing manner in the coarse filter is a spiral manner, so that the filtering effect of coarse filtering is further improved.
Description
Technical field
The utility model relates to a kind of air-strainer, and particularly a kind of medium and heavy long hair style truck is used air-strainer.
Background technique
Conventional multi-stage air cleaner is used the cyclone leaf loop in filter cleaner set inside coarse filtration usually, but can be caused defectives such as the increase of filter cleaner intake resistance, the increasing of housing external diameter simultaneously in order to guarantee filtering efficiency and working life.Be assemblied in the air-strainer at medium and heavy long hair style truck headstock motor position; Installation position and limited space system; Deficiencies such as adopt the multi-stage air cleaner of conventional structure to exist air mass flow can not satisfy the needs of motor, intake resistance is big, and working life is short.In the present disclosed patent documentation, disclose the double filtration device of some external coarse filtration, the strainer of some filter cleaner only is provided with a coarse filtration tube; Some is provided with the coarse filtration tube more than three; The suction port of the filter cleaner of these structures leads directly to, and air does not pass through any filtration when getting into strainer, when relatively poor environmental work; Air can be brought a lot of big impurity into and get into strainer; Also having the air flow in these strainers all is straight-through types, rather than spiral, so there is shortcoming such as poor filtration effect.These external strainers are to be connected on the center line of secondary filter housing in addition; Air through after the coarse filtration inevitably still carries tiny dust granule; Can directly beat on the filter paper of secondary filter through air-flow, long-term work punctures filter paper easily and causes filtration to lose efficacy.
Summary of the invention
The technical problem that the utility model will solve is: provide a kind of external coarse filtration mode, to have reduced intake resistance, filtering efficiency high; The medium and heavy long hair style truck that has prolonged the working life of air-strainer is used air-strainer; The type of flow of the strainer air of this filter cleaner is spiral; Further improve the filtering effect of coarse filtration, solved the problem that exists in the above-mentioned existing technology.
The technological scheme that solves the problems of the technologies described above is: a kind of medium and heavy long hair style truck is used air-strainer; Comprise secondary filter and connect into integrally-built strainer with secondary filter; The suction port UNICOM of the air outlet of strainer and secondary filter; Described secondary filter mainly is made up of shell, fixing rod, main filter core, safe filter core and the bonnet that is installed in outer casing back; Have smart filter suction port and essence on the shell and leach gas port, main filter core, safe filter core are fixed in the enclosure through the fixing rod that is positioned at the shell axis, and bonnet is towards being arranged with secondary filter dust discharge drain opening; Described strainer mainly is made up of two coarse filtration bodies; Each coarse filtration body comprises coarse filtration tube, guard, be arranged on the blade ring of coarse filtration tube front end and be arranged on the coarse filtration steam outlet pipe of coarse filtration tube rear end, and guard is fixed on the front end port of coarse filtration tube, and the coarse filtration tube also has strainer dust discharge drain opening towards next side; Described two coarse filtration tube rear ends are provided with diaphragm, and two coarse filtration body parallel connections also are connected with the secondary filter shell with outer envelope through diaphragm.
Described coarse filtration steam outlet pipe puts in the coarse filtration tube, put in length H be 40mm.
The blade ring of described strainer is the helical blade type blade ring, and described guard is the louvre type guard.
Described strainer is connected the inclined to one side side of secondary filter shell.
The coarse filtration tube of the shell of described secondary filter, strainer and outer envelope all are to adopt steel plate or iron plate to make.
Owing to adopt said structure, heavy long hair style truck is used air-strainer among the utility model, has following beneficial effect:
1, the utility model air-strainer is owing to taked the outer mode that coarse filtration is set; Make and in narrow and small installation space, to make full use of the space; Both satisfied the air output of motor; Reduce intake resistance, guaranteed coarse filtration efficient, the raising filtering efficiency of air-strainer again, prolonged the working life of air-strainer.In addition, the utility model has installed guard additional at the front end of coarse filtration tube, can play the effect of big impurity in maintenance protection, the air-isolation.It is spiral also having the type of flow of air in strainer, has further improved the filtering effect of coarse filtration.
2, the strainer of the utility model is the inclined to one side side that is connected the secondary filter housing, is tangential admission, and is little to the direct impact force of filter paper with respect to the center line air inlet, causes the damaged possibility of filter paper also little.
3, the utility model air-strainer takes strainer directly to be connected with secondary filter, has reduced linkage structure and attached component, has reduced the cost of product, and product with compact structure, volume are little, make and assembling simple.
4, the utility model air-strainer is assemblied on the normal control vehicle headstock motor, receives vibration bigger, and common plastics air filter outer housing strength deficiency shakes easily and splits, and the utility model air filter outer housing all adopts certain thickness steel plate or iron plate to make and guaranteed intensity.
Below, in conjunction with accompanying drawing and embodiment the technical characteristics of heavy long hair style truck among the utility model with air-strainer is further described.
