The surface of the cylinder hole is connected with a thread bulge 10 which is composed of a spiral line of multi-thread. The number of helical threads of the thread projection is generally chosen to be 4 (shown in fig. 4, 7, 8).
In operation, in order to smoothly slide the oil mixed with the oil film and dust particles adhered to the surface of the inner cavity of the cylinder hole down along the dust rotating groove into the oil at the bottom of the inner cavity of the lower shell 13, the height H between the top and the bottom of the dust rotating groove is generally selected to be 6 mm (shown in fig. 7-9).
In order to facilitate people to clean the filter screen of the filter, the locking nuts are quickly disassembled and assembled by hand rotation, and the upper and lower hand-rotating nuts 5 and 7 are generally selected to be butterfly nuts (shown in fig. 1 and 10).
The oil bath type filter (shown in figures 10-12) for the heavy-duty automobile adopting the six-hole spiral groove filter element assembly comprises an outer upper shell 12 and a lower shell 13; wherein, an inner air outlet hole at the top of the inner upper shell 1 is connected and communicated with an outer air outlet hole 12-1 in the inner cavity of the outer upper shell 12, and the inner upper shell 1 is fixedly connected with the top of the inner cavity of the outer upper shell 12; the annular peripheries of the outer upper shell 12, the inner upper shell 1, the lower cylinder seat 11 and the lower shell 13 are elastically pressed, sealed and fixedly connected through a fastening mechanism; an annular flow passage 16 which forms the inner cavity surfaces of the outer upper shell 12 and the lower shell 13 and is formed at intervals relative to the outer peripheral surfaces of the inner upper shell 1 and the lower cylinder seat 11; the air inlet 12-3 of the outer upper shell passes through the annular flow passage 16, sequentially passes through the upper and lower air inlets 1-1, 11-1 on the annular periphery of the inner upper shell 1 and the lower cylinder seat 11 and the bottom of the inner cavity of the lower shell, and is communicated with the inner and outer air outlets of the inner and outer upper shells 1, 12 through the lower and upper filter elements from bottom to top (shown in fig. 10-12).
In order to facilitate the quick connection between the screw rod installed in the inner cavity of the inner upper shell 1 and the top of the inner cavity of the outer upper shell 12, a vertical pipe is usually connected to the inner cavity of the inner upper shell 1, and the screw rod is fixedly connected with a screw hole at the top of the inner cavity of the outer upper shell 12 through a pipe hole of the vertical pipe (shown in fig. 10).
The fastening mechanism is usually provided with a spring buckle 14 connected to the upper end of the lower housing 13, and the lower end surface of the outer upper housing 12, the E-shaped sealing ring 15 connected to the annular outer peripheral edges of the inner upper housing 1 and the lower cylindrical seat 11, and the upper end surface of the lower housing 13 are elastically pressed and sealed and fixedly connected by turning over the spring buckle (fig. 10 and 11).
The outer upper housing 12 is connected at one end to a ramp 12-2, which is typically affixed with a "filter servicing instruction" to facilitate the vehicle operator's viewing of the specification and timely cleaning of the filter screen (shown in fig. 10-12).
When in use (shown in figures 1-12), the bottom of the inner cavity of the lower shell 13 of the invention is provided with engine oil. When the engine of the heavy-duty car runs at high speed, the air flow of the external air to be filtered is sucked into the annular flow passage 16 (shown in figures 10 and 12) through the air inlet hole 12-3 of the outer upper shell 12, the air flow rapidly rotates downwards along the annular flow passage, smoothly passes through the upper air inlet hole 1-1 and the lower air inlet hole 11-1 (shown in figures 2 and 6) on the annular periphery of the inner upper shell 1 and the lower cylinder seat 11, enters the bottom of the inner cavity of the lower shell 13, sweeps and impacts the oil surface of the engine oil, and dust particles contained in the air flow are directly filtered by the engine oil, so that the first oil bath filtration is completed. Oil mist generated by oil swept and impacted by airflow adheres dust particles contained in the airflow after the first oil bath filtration to form oil film dust particles, and the oil film dust particles contained in the airflow are conveyed by centrifugal force generated by strong rotational flow of the rotational flow blades 11-2 at the upper ends of the six cylinder holes of the lower cylinder seat 11 from bottom to top (shown in figure 6), and are respectively adhered to the lower and upper metal wire filter screens 6 and 2 of the lower and upper filter cores and the cylinder hole surfaces of the lower cylinder seat 11 and the upper cylinder seat 9 (shown in figures 10 and 11), so that the second and third oil bath filtration is successively completed. Finally, the filtered air is discharged from an outer air outlet 12-1 of the outer upper shell 12 through an inner air outlet of the inner cavity of the inner upper shell 1, and is subjected to dry filtering by a paper filter element to be supplied to the engine for working. When the engine runs at low speed, oil liquid mixed by oil film dust particles adhered to the upper and lower filter screens 2 and 6 slides down and drops into the engine oil at the bottom of the inner cavity of the lower shell 13. The oil liquid mixed by oil film dust particles respectively adhered to the surfaces of the cylinder holes of the upper cylinder seat 9 and the lower cylinder seat 11 respectively slides downwards along the dust rotating grooves (shown in figures 4, 7, 9 and 11) formed by the thread bulges 10 on the surfaces of the cylinder holes of the upper cylinder seat 9 and the lower cylinder seat 11 to enter the engine oil at the bottom of the inner cavity of the lower shell 13, and the oil bath filtration is repeatedly circulated again.
When oil film dust particles accumulated on the upper filter screen 2 and the lower filter screen 6 of the filter are too much and need to be cleaned (shown in fig. 10), people only need to turn the spring buckle 14 to detach the lower shell 13 below the filter on the ground, rotate the lower hand rotating nut 7 to remove the lower filter element from the hoisting screw rod 3, and detach the lower grid 8, the lower screen seat 11 and the lower filter screen 6 (shown in fig. 1 and 10). Then, the upper hand-rotating nut 5 is rotated to take the upper filter element off the hoisting screw rod 3, the upper grid 4, the upper filter screen 2 and the upper barrel seat 9 are disassembled, the upper filter screen 2 and the lower filter screen 6 with small body shapes can be placed in a basin with small caliber, a small amount of oil liquid is poured into the basin for cleaning (shown in figures 1 and 10), and then the upper filter screen 2 and the lower filter screen 6 are respectively assembled. The oil cleaning device has the advantages of realizing convenient and quick disassembly, cleaning and installation, improving the working efficiency and reducing the cost of oil cleaning.
