the shell is provided with a plurality of first through holes which are uniformly and symmetrically arranged;
a plurality of second through holes which are uniformly and symmetrically arranged are formed in the inner sleeve;
the isolating rings and the magnetic rings are alternately arranged in the ring sleeve.
The number of the first through holes of the shell is equal to that of the second through holes of the inner sleeve, and the first through holes and the second through holes correspond to each other and are matched with each other.
The first through hole and the second through hole are both strip-shaped through holes.
One end of the inner sleeve is provided with a pair of grooves; the inner side of the end cover is provided with a pair of bosses matched with the grooves.
The ring sleeve is a copper sleeve.
The N pole and the S pole of the adjacent magnetic rings are oppositely arranged.
Compared with the prior art, the utility model, have following advantage:
1. not only can filter mechanical impurity particles in the oil, but also can filter magnetized impurities in the oil, so that the impurities cannot enter a hydraulic system and precise hydraulic elements;
2. when the filter element of the coarse oil filter is replaced or cleaned, the oil in the oil tank can be sealed, so that the oil cannot flow out;
3. simple structure and convenient cleaning.

Detailed Description
The present invention will be further described by the following detailed description of a preferred embodiment thereof, taken in conjunction with the accompanying drawings.
As shown in fig. 1, a mesh type magnetic coarse oil filter includes: casing 5, the endotheca 6 of setting in casing 5, set up in the end cover 1 of shell tip, set up the filter core 7 on the inner cylinder face shaft shoulder 12 of end cover 1, still contain: a ring sleeve 8 connected with the inner side of the end cover 1, a plurality of isolating rings 9 arranged in the ring sleeve 8 and a magnetic ring 10.
As shown in fig. 2 to 7, a plurality of uniformly symmetrical first through holes 51 are formed in the shell 5, a plurality of uniformly symmetrical second through holes 61 are formed in the inner sleeve 6, the number of the first through holes 51 is equal to that of the second through holes 61, the first through holes 51 and the second through holes 61 are correspondingly arranged, are matched with each other and are all strip-shaped through holes, and in this embodiment, the number of the first through holes 51 is 4, so as to ensure that the oil passing capacity is more than twice of the flow of the hydraulic pump; one end of the inner sleeve 6 is also provided with a pair of grooves 62, the inner side of the end cover 1 is provided with a pair of bosses 11, the pair of bosses 11 is matched with the pair of grooves 62, and the pair of bosses 11 is inserted into the pair of grooves 62 during assembly; a plurality of isolating rings 9 and magnetic rings 10 are arranged in the ring sleeve 8 at intervals, and the N pole and the S pole of the adjacent magnetic rings 10 are arranged oppositely, in this embodiment, the ring sleeve 8 is a copper sleeve.
When the oil filter is used, the relative position of the end cover 1 is positioned by using the positioning screw 15 of the oil filter, so that the four strip-shaped through holes on the shell 5 and the inner sleeve 6 are all in the same circumferential angle, namely, the first through hole 51 and the second through hole 61 are ensured to be vertically corresponding, the oil passing amount is maximum, and the oil passing effect is best; when oil passes through, the isolating ring 9 filters and isolates mechanical impurity particles in the oil, and the magnetic ring 10 filters impurities capable of being magnetized in the oil, so that the mechanical impurities can be filtered and isolated, the impurities capable of being magnetized can be filtered, related impurities cannot enter a hydraulic system and a precise hydraulic element, and the performance of the hydraulic system is ensured;
when the filter element 7 on the upper surface needs to be replaced or cleaned, parts such as screws, gaskets, positioning screws 15 and the like are firstly dismounted, and then two screws are screwed into the jackscrew hole of the end cover 1, so that the end cover 1 rotates by 45 degrees, because a pair of bosses 11 on the end cover 1 are matched with a pair of grooves 62 of the inner sleeve 6, the inner sleeve 6 rotates by 45 degrees along with the end cover 1, a first through hole 51 on the shell 5 and a second through hole 61 on the inner sleeve 6 are not in the same circumferential angle and are staggered by 45 degrees, so that the first through hole 51 and the second through hole 61 are guaranteed to be mutually sealed, oil in the oil tank cannot flow out, then the end cover 1 is taken down, and the filter element 7 is replaced or cleaned.
