Description
Technical field
The utility model belongs to air cleaner technical field more particularly to a kind of air filter for generator.
Background technique
Air filter is mainly used in the fields such as pneumatic machinery, diesel machine, and effect is to provide cleaning for these mechanical equipments
Air, suck the air with impurity particle at work to prevent these mechanical equipments and increase the probability of abrasion and damage.
The chief component of air cleaner is filter core and casing, and wherein filter core is main filtration fraction, carries the mistake of gas
Work is filtered, and casing is that provide for filter core must external structure to be protected.
Air filter is the chief component of engine aspirating system, and air filter does not still provide clean sky to engine
Gas also plays an important role engine charge noise reduction, especially generator air filter, but air filter on the market at present
The structure setting of device noise reduction part obtains too simple, and noise elimination soundproof effect is bad.
Utility model content
The purpose of this utility model is to provide a kind of air filters for generator, solve the air filter of the prior art
The problem of noise elimination sound insulation difference.
In order to achieve the above object, the base case of the utility model are as follows: for the air filter of generator, including shell and
With the matched lid of shell, shell is divided into the two-part partition in anechoic chamber and filter chamber, anechoic chamber by interior be equipped with of the shell
It is interior to be equipped with lower S-shaped air flue, the upper S shape air flue opposite with lower S-shaped air flue, upper S-shaped air flue and lower S-shaped gas are equipped in the lid
Rubber pad is equipped between road；The filter layer for filtering gas is equipped in filter chamber；It is provided on the shell opposite with filter layer
Exhaust outlet and allow gas to enough enter lower S-shaped air flue, the air inlet in upper S-shaped air flue；It is additionally provided in filter chamber and is located at filtering
Exhaust gas baffle between layer and exhaust outlet.
The working principle of this base case is: when using air filter of the invention, extraneous gas passes through air inlet point
S-shaped air flue Jin Ru not descended, in upper S-shaped air flue, under the collective effect of upper S-shaped air flue and lower S-shaped air flue, erasure effect is obvious.
Gas crosses partition subsequently into filter chamber after upper S-shaped air flue, lower S-shaped air flue is discharged, and filter layer is filtered gas, mistake
Gas after filter is discharged from exhaust outlet.
The beneficial effect of this base case is:
1, S-shaped air flue and lower S-shaped air flue in setting are separated upper S-shaped air flue and lower S-shaped air flue using rubber pad, from
The gas that air inlet enters separately flows into S-shaped air flue, in lower S-shaped air flue, and gas can be buffered greatly, be greatly improved
The effect of noise elimination sound insulation.
2, it in the environment of air filter work, is distributed with outside air filter and elaioleucite, exhaust gas is atomized by the exhaust gas that cylinder head generates
Atomization elaioleucite can enter air filter by exhaust outlet, and exhaust gas baffle can effectively stop exhaust gas atomization elaioleucite, avoid exhaust gas
Atomization elaioleucite is adhered on filter paper, so that filter paper is drenched, the filter capacity of filter paper is caused to reduce, and intake resistance increases, simultaneously
Exhaust gas baffle can also stop flame, and flame is avoided to burn filter paper.
Further, the filter layer successively includes foam filter elements and the filter paper opposite with exhaust outlet from top to bottom.Use bubble
Foam filter core and filter paper are filtered gas, foam filter elements to gas carry out coarse filtration, and filter paper to gas carry out refined filtration, effectively every
Impurity particle in exhausted air, the effect of filtering are good.
Further, S-shaped partition is equipped in upper S-shaped air flue and lower S-shaped air flue.S-shaped partition is upper S-shaped air flue, lower S-shaped gas
Road is divided into smaller area of space, and gas can obtain bigger buffering when flowing through S-shaped air flue, lower S-shaped air flue, be conducive to
Noise reduction.
Further, the bracket for fixing exhaust gas baffle is equipped in filter chamber, the exhaust gas baffle is rolled towards exhaust outlet one
It is arranged obliquely.Exhaust gas baffle can stop " gaseous mixture ", and exhaust gas baffle is arranged diagonally downward towards exhaust outlet side, " gaseous mixture "
In elaioleucite condensation when can along exhaust gas baffle to exhaust outlet side slide, be conducive to the gas being discharged from air filter for elaioleucite one
It is same to take away.
Further, the edge of filter paper towards exhaust outlet side is equipped with the PU foaming glue-line of annular.The setting of PU foaming glue-line
The leakproofness between filter layer and shell is enhanced, avoids some gases without filtering and is directly discharged from exhaust outlet.
Further, the ring frame cooperated with filter chamber is equipped in the lid, the side of ring frame towards anechoic chamber is provided with
Inflow entrance, inflow entrance are located at close to the side of lid.Inflow entrance is located at close to the side of lid, enters in filter chamber from anechoic chamber
Gas be located at the tops of foam filter elements, guarantee that gas can pass sequentially through foam filter elements, filter paper.
