Description

Technical Field

[0001] The utility model relates to the technical field of oil tanks, and more specifically, to an oil tank with a multiple filtering structure. Background Art

[0002] Fuel tanks are containers for storing oil liquids and are widely used in the fields of motor vehicles, machinery, chemicals, and pharmaceuticals. The fuel used in daily life is mixed with a variety of impurities. A single filtering method can only filter out a small number of specific impurities. The remaining impurities will still enter the engine through the oil path and settle at the bottom of its oil pan. Long-term use of this unfiltered fuel will not only affect the working efficiency of the engine, but also reduce the overall service life of the engine and shorten its maintenance cycle.

[0003] The existing oil tank has the following shortcomings: the oil temperature is uneven and the temperature difference of the oil is large. Secondly, when the return oil rushes into the oil tank, it will roll and produce foam, which will cause air to enter the oil suction pipe and unstable pressure. Finally, the impurities and iron filings in the oil tank are not filtered, which will affect the service life of the equipment.

[0004] A Chinese patent application with patent number CN202022439025.5 discloses an oil tank with multi-stage filtration, wherein a hollow shell is provided outside the oil tank body, and the shell provided outside the oil tank body is arranged in a concave structure, and a first sieve plate is fixed at the central axis of the oil tank body to divide the inner cavity of the box body into an oil inlet area and a coarse filter area, and a third sieve plate is fixed at the central axis of the shell to divide the inner cavity of the shell into a fine filter area and an oil outlet area, and an oil outlet hole connecting the coarse filter area and the fine filter area is provided at the bottom of the oil tank body, and the oil outlet hole is covered with a second sieve plate, and two first oil outlets and second oil outlets respectively connected to the fine filter area and the oil outlet area are provided on the outer wall of the shell; the oil tank with multi-stage filtration provided by the utility model can filter and clean the recovered oil to ensure that the oil used subsequently is free of impurities;

[0005] Then, it can be seen from the drawings in the specification that multi-layer filtration of the fuel is achieved by means of the filter screen and sieve plate arranged inside the fuel tank, and the filtered impurities are located on one side of the filter screen of the fuel tank, which is inconvenient to clean and use, thus affecting the service life.
