Abstract
The utility model discloses an oil-bath-type air cleaner. The oil-bath-type air cleaner includes a shell (6), an air inlet (5), an air outlet, and a filter inner cavity and a filter screen arranged in the shell. The oil-bath-type air cleaner is characterized in that the filter screen is a three-layer screen. A first-layer filter screen, a second-layer filter screen, and a third-layer filter screen (61, 62, 63) are arranged in the filter inner cavity from the air inlet (5). A first sealing ring is arranged between the third-layer filter screen (63) in the shell and the shell (6). A second sealing ring (2) is arranged between the second-layer filter screen (62) and the third-layer filter screen (63). Whirling fan (7) are arranged in air inlet positions of the first-layer filter screen, a second-layer filter screen, and a third-layer filter screen (61, 62, 63) and on the center of a contact face of an upper layer of the first-layer filter screen (61) and the second-layer filter screen (62). By using the oil-bath-type air cleaner provided by the utility model, the sealing performance in the shell is improved, thereby preventing oil leakage and air leakage and avoiding second pollution to air. And the oil-bath-type air cleaner improves the air purity after the air is filtered.
Description
Technical field
The utility model relates to air-strainer, particularly a kind of oil bath air cleaner.
Background technique
Common oil bath air cleaner comprises housing, and suction port, air outlet, and the filtering inner chamber in the housing are provided with filter screen at inner chamber, and filter screen is connected with housing through screw thread.Air arrives pasta from suction port through intake duct; Because the mobile pasta that makes of air rises to filter screen; Make the aerosol of oil, gas, dust continue to rise to the cascade filtration net through swirl vane, arrive gas, from the air outlet entering motor of filter cleaner through the chamber.But because housing all is threaded with filter screen, this connection is poorly sealed, often causes leakage of oil, gas leakage, brings secondary pollution to air; Moreover because dust is many in the air, the two-stage filter screen still can not be with the dust filtering, and the air that contains dust so also can get into motor, influences the power and the life-span of motor, has also strengthened the replacing frequency and maintenance frequency of filter cleaner simultaneously.
Summary of the invention
The utility model is for overcoming above-mentioned deficiency, and the oil bath air cleaner that a kind of good sealing effect is provided and engine air is more cleaned.
The technological scheme that the utility model adopted is: oil bath air cleaner comprises housing; Filter screen is established at inner chamber in suction port, air outlet, and the filtering inner chamber in the housing; Filter screen is connected with housing through screw thread; Said filter screen divides the three-stage filtration net, promptly establishes one, two, three filter screen at the filtering inner chamber successively by suction port, in said housing, between third level filter screen and the housing seal ring is set; Between second level filter screen and third level filter screen, seal ring is set, establishes the eddy flow fan at one, two, three filter screen suction port place and in the middle of first order filter screen upper strata and cascade filtration net surface of contact.
Traditional oil bath air cleaner has only the I and II filter screen, and the utility model has been set up the three-stage filtration net, makes the aeroscope after filtering higher; The utility model has improved the enclosure interior sealing owing to increased seal ring in enclosure interior, prevents leakage of oil, gas leakage, avoids air secondary to pollute; The newly-increased eddy flow fan of the utility model, the eddy flow fan can be broken up the gas of process, oil, dirt makes it evenly to pass through filter screen, and the filtration of air is more thorough.
Description of drawings
Fig. 1 is the structural representation of the utility model oil bath air cleaner.
Embodiment
As shown in Figure 1; Oil bath air cleaner comprises housing 6, suction port 5, air outlet, and the filtering inner chamber 4 in the housing 6; Establish filter screen at inner chamber 4; Filter screen is connected with housing 6 through screw thread, establishes one, two, three filter screen 61,62,63 at filtering inner chamber 4 successively by suction port 5, and first seal ring 1 is set between third level filter screen 63 in housing 6 and the housing 6; Second seal ring 2 is set between cascade filtration net 62 and three-stage filtration net 63, establishes eddy flow fan 7 at one, two, three filter screen 61,62,63 suction port places and in the middle of one-level filter screen 61 upper stratas and cascade filtration net 62 surface of contact.Air arrives oil baffle 3 from suction port 5 through intake duct, makes the aerosol of oil, gas, dust continue to rise to one, two, three filter screen 61,62,63 through swirl vane.
The utility model oil-bath filter makes full use of the stickiness of machine oil, can remove dust in air, and in time is fixed on dust in air in the machine oil drop, and the air that can not be run up sucks cleaned air passes once more.
Traditional oil bath air cleaner raw material are iron construction, and the utility model oil-bath filter is a plastic construction, and it is fast to have a moulding, and cost is low, good effectiveness.
Claims (1)
1. oil bath air cleaner; Comprise housing; Suction port, air outlet, and filtering inner chamber and filter screen in the housing, it is characterized in that: said filter screen is three grades; Promptly establish one, two, three filter screen (61,62,63) successively by suction port (5) at filtering inner chamber (4); Between third level filter screen (63) in housing (6) and the housing (6) first seal ring (1) is set, between cascade filtration net (62) and three-stage filtration net (63), second seal ring (2) is set, establish eddy flow fan (7) at one, two, three filter screen (61,62,63) suction port place and in the middle of one-level filter screen (61) upper strata and cascade filtration net (62) surface of contact.
