Detailed Description

The following describes in detail specific embodiments of the present invention. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.

The invention provides a recycled engine oil filter, which comprises a shell 1 with an oil inlet 2 and an oil outlet 3, a filter element 4, a chip storage area 5 and a rotating motor 6, as shown in figures 1-5; the shell 1 is of a hollow structure, and the filter element 4 is rotatably arranged in the shell 1 and is fixedly connected with an output shaft of a rotating motor 6; the filter element 4 is a rotary body structure, the edge of the filter element is composed of a plurality of continuous connection of recesses 41 and protrusions 42, and the protrusions 42 are in contact with the shell 1; the chip storage area 4 is formed in the housing 1 and is positioned on one side of the filter element 4, which occupies the inner area of the housing 1. Preferably, as shown in fig. 3, the recesses 41 and the protrusions 42 of the filter insert 4 are adjacent to each other, forming an annular corrugated shape.

It should be noted that the scrap-storage area 5 is required to be arranged at the lowest part of the device during assembly, so as to ensure the precipitation of metal scraps.

Through above-mentioned technical scheme's setting, can effectively shunt piece and machine oil to with the piece separation on filter core 4, deposit and to have depositing bits district 5, alleviated the problem that efficiency descends is strained to the machine in the use, effectively prolonged its life.

The working process is as follows: the engine oil enters the shell 1 from the oil inlet 2, passes through the filter element 4, enters the filter element 4, and passes through the filter element 4 from the inside to the oil outlet 3 again to store the oil; the metal impurities are isolated outside the filter element 4 by the filter element 4. At this time, the rotating motor 6 is in operation and rotates slowly, and the metal chips are isolated between the two protrusions 42, namely in the recess 41, and are carried to the chip storage area 5 by the rotating filter element 4 for sedimentation. At above-mentioned in-process, machine oil process filter core 4 twice at least, the filter effect is good, and metal debris attaches at the surface of filter core 4, under the impact that 4 centrifugal force of filter core and inside machine oil flow, can break away from the filter core, thereby effectively prevent that the filter core from leading to filter core 4 efficiency to metal debris's absorption and descending.

In order to prevent the separated metal scraps from being carried to the oil outlet 3 by the protrusion of the filter element 4, the scrap storage area is provided with two partition plates which are V-shaped, the lower end of the V-shaped is an opening, so that the scraps can conveniently pass through, one end of the partition plate close to the filter element 4 is provided with a cavity, a sliding plate which is slidably arranged in the cavity, and two springs which are respectively connected with the sliding plate and the cavity, so that the partition plate is attached to the two concave sides of the filter element 4.

The technical scheme comprises the following working procedures: the metal debris generated by the secondary filtration of the engine oil can be separated from the filter element 4 when passing through the oil inlet 2, and is driven by the liquid flow to collide with the impurity absorption cylinder 7, so that the metal debris enters the impurity absorption cylinder 7 through the filter hole 71. Since the filter holes 71 have a large outer diameter and a small inner diameter, the filter holes 71 entering the impurity absorbing cylinder 7 have a large volume and cannot exit the filter holes 71. The one-way membrane 72 can be opened to the entrance when metal debris enters and can also be bent to open when metal debris has a tendency to exit, but the one-way membrane 72 itself has a thickness, thereby reducing the diameter of the filter hole 72 and further achieving the effect of collecting the metal debris.
