Abstract
The utility model relates to a double-chamber air filter, which belongs to the technology of filtering intake air of an internal-combustion engine. The double-chamber air filter comprises a lower casing, an upper cover, a wet-type filter element, a dry-type filter element, a partition plate, an air outlet pipe and the like. The air outlet pipe is mounted at the bottom of the lower casing by the aid of screws; screw rods are arranged at the bottom of an inner cavity; the upper cover is mounted on the upper portion of the lower casing; the partition plate is arranged inside the lower casing; the wet-type filter element and the dry-type filter element in the inner cavity of the lower casing are isolated into two chambers by the partition plate; and the two chambers are communicated for ventilation by a vent hole arranged on the upper portion of the partition plate. In the chamber provided with the wet-type filter element, the upper cover is provided with an air inlet pipe, the lower portion of the air inlet pipe is inserted into the center of the wet-type filter element, a cyclone seat is mounted on the upper portion of the air inlet pipe, a dust collecting cup is mounted on the cyclone seat, a coarse filter cover is mounted on the upper portion of the dust collecting cup, and the coarse filter cover is screwed up by a butterfly nut and the screw rod penetrating through the center of the coarse filter cover. In the chamber provided with the dry-type filter element, a rubber cushion is arranged at the connected position of the dry-type filter element and the lower casing, the other screw rod is sleeved with a spring after penetrating through the center of the dry-type filter element, and then the screw rod is screwed up by another butterfly nut after being provided with a cover. By adopting the scheme, the double-chamber air filter has the advantages of high filtering efficiency.
Description
Technical field
A kind of double chamber type air-strainer belongs to the technical field of filtering air-intake of combustion engine.
Background technique
At present, air cleaner for internal combustion engine generally adopts a kind of filter element filtering, and the filtering effect is undesirable, air inlet is stopped up very fast, original doing wet in conjunction with air-strainer, can not use on some specific internal-combustion engines, therefore needs a kind of filter cleaner can give specific internal-combustion engine supporting.
Summary of the invention
For above-mentioned reasons, the utility model has designed a kind of double chamber type air-strainer, its objective is the needs that are fit to specific engine, finishes the purpose of filtered air.
Its objective is and such realization design a kind of double chamber type air-strainer, it is by lower shell body, loam cake, and the wet type filter core, dry type filter element, dividing plate, parts such as steam outlet pipe are formed; Steam outlet pipe is installed with spiral in the lower shell body bottom, and the bottom of inner chamber is provided with lead screw, and loam cake is installed on lower shell body top; Lower shell body inside is provided with dividing plate, with dividing plate the wet type filter core and the dry type filter element of lower housing cavity is isolated into two chambers, and two chambers were communicated with gas by the vent that is located at dividing plate top.In the chamber that the wet type filter core is installed, on be covered with suction tude, the center of wet type filter core is inserted in the bottom of suction tude, swirl base is equipped with on the top of suction tude, be equipped with above the swirl base and gather the dirt cup, the coarse filtration lid is equipped with on poly-dirt cup top, and the coarse filtration lid screws with the lead screw of passing coarse filtration lid center by dish is female.In the chamber of dry type filter element was installed, the joint of dry type filter element and lower shell body was provided with rubber pad, and lead screw is passed pocketed springs behind the center of dry type filter element, screwed with the dish mother after loam cake is installed again.
Owing to adopted such scheme, this double chamber type air-strainer has the filtering efficiency height, and long service life meets the needs of specific engine.
Description of drawings
Accompanying drawing is the structure sectional view of double chamber type air-strainer
Among the figure: 1 lower shell body, 2 loam cakes, 3 wet type filter cores, 4 suction tude, 5 poly-dirt cups, 6 swirl bases, 7 coarse filtration lid, 8 dividing plates, 9 vents, 10 dry type filter elements, 11 lead screw, 12 dish mothers, 13 spirals, 14 steam outlet pipes, 15 rubber pads, 16 springs.
Embodiment
Referring to accompanying drawing: the double chamber type air-strainer, it is by lower shell body 1, loam cake 2, wet type filter core 3, dry type filter element 10, dividing plate 8, steam outlet pipe 14 parts such as grade are formed; Steam outlet pipe 14 is installed with spiral 13 in lower shell body 1 bottom, and the bottom of inner chamber is provided with lead screw 11, and loam cake 2 is installed on lower shell body 1 top; Lower shell body 1 inside is provided with dividing plate 8, with dividing plate 8 the wet type filter core 3 and the dry type filter element 10 of lower shell body 1 inner chamber is isolated into two chambers, and two chambers were communicated with gas by the vent 9 that is located at dividing plate 8 tops.In the chamber that wet type filter core 3 is installed, loam cake 2 is provided with suction tude 4, the center of wet type filter core 3 is inserted in the bottom of suction tude 4, swirl base 6 is equipped with on the top of suction tude 4, poly-dirt cup 5 is housed above the swirl base 6, coarse filtration lid 7 is equipped with on poly-dirt cup 5 tops, and coarse filtration lid 7 is by dish female 12 and pass coarse filtration and cover the lead screw 11 at 7 centers and screw.In the chamber of dry type filter element 10 was installed, the joint of dry type filter element 10 and lower shell body 1 was provided with rubber pad 15, and lead screw 11 is passed pocketed springs 16 behind the center of dry type filter element 10, loam cake 2 backs is installed again screws with dish mother 12.
Working principle: in the work, air enters from the bottom of swirl base 6 and forms air-flow rotatably, dust in air inwall along poly-dirt cup 5 under action of centrifugal force upwards arrives in the inner chamber of poly-dirt cup 5, air after the coarse filtration enters the bottom of wet type filter core 3 through suction tude 4, be upward through wet type filter core 3 again, air after wet type filter core 3 filters enters the indoor of dry type filter element 10 by the vent 9 on dividing plate 8 tops, air after dry type filter element 10 filters enters steam outlet pipe 14, enter internal-combustion engine by steam outlet pipe 14, realized the filtration of air.
