Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Example (b):
as shown in fig. 1 to 5, an oil tank filtering device is installed on an oil filler, and includes a primary filter cartridge 1, the primary filter cartridge 1 has a plurality of primary filter holes 2 on an outer circumferential surface thereof, both ends of the primary filter cartridge 1 are respectively provided with an upper cover 3 and a lower cover 4, the upper cover 3 is covered with one end of the primary filter cartridge 1, so as to enable the upper cover 3 to be in an openable state, the lower cover 4 is fixedly connected with the other end of the primary filter cartridge 1, an oil inlet 5 is provided in a middle portion of the upper cover 3, a secondary filter cartridge 6 is provided inside the primary filter cartridge 1, the secondary filter cartridge 6 is arranged along an axial direction of the primary filter cartridge 1, the secondary filter cartridge 6 is communicated with the oil inlet 5 to form an oil inlet passage, and the secondary filter cartridge 6 has a plurality of secondary filter holes 7 on an. When oil is added, the fuel is firstly filtered for the first time through the secondary filter cylinder 6, flows into the primary filter cylinder 1 through the secondary filter hole 7 after the filtration is finished, and finally flows out through the primary filter hole 2; the primary filter cartridge 1 and the secondary filter cartridge 6 are combined for use, so that secondary filtration of the fuel oil is realized, and particulate matters contained in the fuel oil are filtered more thoroughly; in addition, because the nozzle can stretch into the oil inlet channel through the oil inlet 5, can not contact with the first-stage filter cartridge 1 or the second-stage filter cartridge 6, so can not cause the nozzle to puncture the condition of filter cartridge, prolonged this filter equipment's life.
The middle of the lower surface of the upper sealing cover 3 is provided with an annular flange 8 extending towards the axis direction of the primary filter cartridge 1, the annular flange 8 and the upper sealing cover 3 are integrally formed, the oil inlet 5 is positioned in the annular flange 8, the inner circumferential surface of the annular flange 8 is provided with internal threads, the upper surface of the lower sealing cover 4 is fixedly connected with a fixed seat 9, the fixed seat 9 and the annular flange 8 are oppositely arranged, the outer circumferential surface of one end of the secondary filter cartridge 6 is provided with external threads matched with the internal threads, and the other end of the secondary filter cartridge 6 is inserted into the fixed seat 9. Because the both ends of secondary filter cartridge 6 are can dismantle the connection, thereby the detachable purpose of secondary filter cartridge 6 has been realized, rotary upper sealing cap 3, make the one end separation of annular flange 8 and secondary filter cartridge 6, take out secondary filter cartridge 6 on the fixing base 9 (perhaps, outwards mention upper sealing cap 3 earlier, make secondary filter cartridge 6 separate with fixing base 9 earlier, then rotatory secondary filter cartridge 6 again, make it separate with annular flange 8), thereby be convenient for change secondary filter cartridge 6, prevent the long-time jam of secondary filter hole 7, the influence filters, the fuel condition of flowing.
The filter is characterized by further comprising a filter element 10, a groove is formed in the middle of the fixing seat 9, one end of the filter element 10 is inserted into the fixing seat 9 through the groove, the other end of the filter element 10 extends to be close to the oil inlet 5, and the filter element 10 is located inside the secondary filter cylinder 6. Because the filter element 10 is in a movable inserting state, the filter element can be separated from the fixed seat 9, and when the two-stage filter cylinder 6 is in an opening state, the filter element 10 can be replaced, so that the condition of incomplete filtration is prevented.
An annular convex part 11 extends downwards from the edge of the upper sealing cover 3, the annular convex part 11 and the upper sealing cover 3 are integrally formed, and an annular buckling part 12 is formed between the annular convex part 11 and the upper sealing cover 3. The annular snap portion 12 cooperates with a flange on the filler neck such that when the filter assembly is installed on the filler neck, the annular snap portion 12 can snap into the flange on the filler neck.
In order to better install the filtering device on the oil filling port, the annular buckling part 12 is provided with two oppositely arranged fixing holes 13, a bolt 14 linearly penetrates through the annular buckling part 12 through the fixing holes 13, and the filtering device is installed on the oil filling port through the bolt 14, so that the filtering device is prevented from loosening during bumping.
The diameter of the first-stage filtering hole 2 is smaller than that of the second-stage filtering hole 7, so that particles with different sizes can be conveniently filtered.
The working principle of the embodiment is as follows: when refueling, the refueling gun extends into the oil inlet channel through the oil inlet 5, then oil is filled, fuel oil is firstly filtered through the filter element 10, then is filtered again through the secondary filter hole 7 on the secondary filter cylinder 6 and flows into the primary filter cylinder 1, and the primary filter hole 2 filters residual particles and then flows out through the hole.
In the embodiment, two-stage filtration is realized through the first-stage filter cartridge 1 and the second-stage filter cartridge 6, so that particulate matters contained in the fuel oil are filtered more thoroughly; in addition, the oil inlet channel is cylindrical, so that the oil gun cannot touch any filter medium, the situation that the oil gun punctures the filter medium is avoided, and the service life of the filter device is prolonged; and, filter core 10 and secondary filter section of thick bamboo 6 are detachable state, realize filtering medium's change, the effectual condition that prevents that primary filter hole 2, secondary filter hole 7 from blockking up.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
