Multi-stage filtering oil bath type air filter

Technical Field

The utility model belongs to the technical field of the filter, concretely relates to multistage filtration oil bath formula air cleaner.

Background

The filter is a device that filters impurities or gas through a filter paper or a filter net. The method is divided into the following steps according to different filtering functions: oil filters, fuel filters (gasoline filters, diesel filters, oil-water separators, hydraulic filters), air filters, air-conditioning filters, and the like. The air filter (air filter) is mainly applied to the fields of pneumatic machinery, internal combustion machinery and the like, and is used for providing clean air for the mechanical equipment so as to prevent the mechanical equipment from sucking air with foreign particles in work and increasing the probability of abrasion and damage. The main components of an air cleaner are a filter element, which is the main filtering part, which undertakes the filtering of the gas, and a housing, which is the external structure that provides the necessary protection for the filter element. The existing air filter mostly adopts a single-stage filtering mode, so that the filter cannot adapt to the environment with high dust concentration, and has great limitation.

Multistage filtration oil bath formula air cleaner, including rose box, secondary filter, primary filter, oil bath, its characterized in that: the upper portion of rose box inner chamber is fixed with the baffle of horizontal direction, the baffle lateral part is equipped with a plurality of through-hole, the middle part of baffle is fixed with the blast pipe of vertical direction, the lower part of blast pipe is worn out from the bottom plate of rose box, the outside on blast pipe upper portion is equipped with the secondary filter, the inboard of secondary filter is connected with the blast pipe, the outside of secondary filter is connected with the inner wall of rose box, the sleeve is passed at the middle part of blast pipe, be fixed with the primary filter of horizontal direction between sleeve and the blast pipe, the outside of lower part is fixed on the inner wall of rose box through upper fixed plate, bottom plate respectively on the sleeve, the lower part region of bottom plate is the oil bath, be fixed with the air duct of a plurality of groups on the bottom plate, the air duct inserts in the.

Preferably, the oil pool contains engine oil.

Preferably, a tangential air inlet pipe is fixed on the side part of the filter box, and the air inlet pipe is communicated with the area between the upper fixing plate and the lower fixing plate.

Preferably, a gap is arranged between the lower end of the sleeve and the bottom plate of the filter box, and a gap is arranged between the upper end of the sleeve and the secondary filter.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses when using, the rose box lateral part need install with oil pipe and oil extraction pipe, blast pipe and engine intake-tube connection, when the engine breathes in, the air gets into from the intake pipe, under the suction effect of engine, the air gets into the oil bath along the air duct, the air passes the machine oil in the oil bath, most particulate matter meeting adhesion in the air is in the machine oil in the oil bath, the air is from the blast pipe, clearance between the sleeve upwards flows, pass one-level filter in proper order, secondary filter filters, the air after the filtration passes the through-hole on the baffle, finally follow the blast pipe and discharge and get into the engine. Large-particle dust in the air is adsorbed by the engine oil, so that the service lives of a secondary filter and a primary filter are greatly prolonged; through inserting the air duct in the oil bath, can effectively improve the absorbent efficiency of machine oil to improve whole filtration efficiency.
