Abstract

The utility model discloses a multi-stage oil bath type air filter, which comprises a filter casing. The bottom of an inner cavity of the filter casing is provided with a horizontal oil tank, filter oil is stored in the oil tank, an air inlet end guide plate is arranged above the oil tank, and the lower portion of the air inlet end guide plate is arranged under the oil face of the filter oil in the oil tank. The air inlet end guide plate is fixedly connected with a horizontal spiral-shaped spiral channel which is arranged above the oil tank, the upper end of the spiral channel is sealed, the lower portions of each spiral of the spiral channel is immersed in the filter oil in the oil tank, the other end of the spiral channel relative to the air inlet end guide plate is provided with an air outlet end guide plate communicated with a subsequent filter device or an air outlet pipe. The depth of the filter oil in the oil tank is 2 centimeters. The multi-stage oil bath type air filter performs circulating oil bath on dust-containing air repeatedly, enlarges contacting time and area between the air and the filter oil, is low in cost and effectively protects an engine.

Description

Multistage oil bath air cleaner

Technical field

The utility model relates to a kind of air-strainer, specifically is meant a kind of multistage oil bath air cleaner with filtering oil.

Background technique

Oil bath air cleaner is to carry out airfiltering by the adsorptivity of filtering oil to dust laden air; Existing oil bath air cleaner; Belong to the inertia oil-bath filter, promptly introduce oil sump to dust laden air from the inlet hole of filter cleaner, a part of dust is glued by filtering oil to be removed; The dust laden air of carrying mist of oil afterwards secretly remakes further filtration, gets back to oil sump and tackled the dust that gets off by follow-up filter core with filtering oil.It is little that inertia-oil bath type air cleaner has intake resistance, can adapt to the rocky working environment of many dirt, and advantages such as long service life adopt this mode filtered air on the motor of former automobile in multiple model, tractor.But this air-strainer filtering efficiency is lower; Just in filtering oil, passed through disposable inertia filtering, though carried out coarse filtration, can not the reasonable use filtering adhesion characteristics of oil; Can not be filtered fully, also therefore influenced the working life of follow-up filter.

The model utility content

The utility model technical issues that need to address provide a kind of multistage efficiently oil bath air cleaner.

For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:

Multistage oil bath air cleaner; Comprise filter case; The bottom of filter box intracoelomic cavity be provided with level in have the oil sump of filtering oil; The oil sump top is provided with the bottom and is positioned at the inlet end guide plate under the oily pasta of oil sump filtering; Said inlet end guide plate is fixedly connected with the helical duct of the flat spin shape of the upper end closed that is arranged on above the oil sump, and the filtering oil in the oil sump is immersed in the bottom of every spiral of helical duct, and the other end setting of the relative inlet end guide plate of helical duct is communicated to the outlet side guide plate of follow-up filter or steam outlet pipe.

The further improvement of the utility model is: the degree of depth of filtering oil is 2 centimetres in the said oil sump.

Because the technological progress of having adopted technique scheme, the utility model to obtain is:

The utility model is designed to repeatedly sticking removing playing sticking disposable sticking the removing of removing effect of inertia, gives full play to the adhesion characteristics of filtering oil, and does not increase resistance of air.Dust laden air is carried out repeatedly circuit oil bath, increased time and area that air and filtering oil contacts, cost is low, effectively protected motor indirectly.

Wherein, 1, suction tude, 2, steam outlet pipe, 3, helical duct, 4, the metal filter, 5, the papery filter, 6, viewing window, 31, oil sump, 32, the inlet end guide plate, 33, outlet side guide plate.

Embodiment

Below in conjunction with accompanying drawing the utility model is explained further details:

Multistage oil bath air cleaner, as shown in the figure, wherein Fig. 1 is the bigger air-strainer of structure space, is provided with the whole horizontal oil sump 31 of one that is in the bottom of filter box intracoelomic cavity, the degree of depth of filtering oil is 2 centimetres in the said oil sump.The both sides of oil sump are provided with helical duct 3 between inlet end guide plate 32, outlet side guide plate 33, two guide plates respectively.The dust laden air that gets into the suction tude 1 of filter cleaner gets into oil sump 31 from inlet end guide plate 32; Get into helical duct 3 afterwards again; The upper end closed of helical duct; Then air can only wriggle along helical duct and move ahead, and it is inner that oil sump is immersed in the bottom of every spiral of helical duct 3, and process several filtered air gets into follow-up filtrating equipment from outlet side water conservancy diversion 33 plates of oil sump 31 opposite side settings.

Fig. 2 is the smaller air filter of structure space.Be provided with horizontal oil sump 31 in the bottom of filter case, the degree of depth of filtering oil is 2 centimetres in the said oil sump.The suction tude 1 of cleaner top section directly is communicated to the housing intracavity bottom; The place of the corresponding suction tude of oil sump is provided with inlet end guide plate 32; The avris of filter case is provided with between outlet side guide plate 33, two guide plates spiral helicine helical duct is set, and helical duct 3 also moves into the tracheae rotation in self spiral; Be communicated to the outlet side guide plate at last, so that carry out follow-up filtration through the air of multiple times of filtration.

Claims

1. multistage oil bath air cleaner; Comprise filter case; The bottom of filter box intracoelomic cavity be provided with level in have the oil sump (31) of filtering oil; The oil sump top is provided with the bottom and is positioned at the inlet end guide plate (32) under the oily pasta of oil sump filtering; It is characterized in that: said inlet end guide plate (32) is fixedly connected with the helical duct (3) of the flat spin shape that is arranged on the upper end closed above the oil sump (31), and the filtering oil in the oil sump is immersed in the bottom of every spiral of helical duct, and the other end setting of the relative inlet end guide plate of helical duct (3) is communicated to the outlet side guide plate (33) of follow-up filter or steam outlet pipe.

2. multistage oil bath air cleaner according to claim 1 is characterized in that: the degree of depth of filtering oil is 2 centimetres in the said oil sump.
