DETAILED DESCRIPTION

[0014] The utility model will be made further detailed below with the embodiment given by the accompanying drawings.

[0015] Referring to Figs. 1-2 The filter core with magnet of the embodiment includes a filter core barrel 1 and a mounting seat 2 arranged at one end of the filter core barrel 1, a bypass hole 3 is arranged at the other end of the filter core barrel 1, a bypass valve 4 is arranged in the filter core barrel 1, the bypass valve 4 is adjacent to the bypass hole 3, a first magnet 51 in the shape of a ring is arranged on the mounting seat 2, a second magnet 52 is arranged at the other end of the filter core barrel 1, the second magnet 52 is arranged in the shape of a ring and has an interval 6 with the bypass hole 3.

[0016] Through the above technical solution, when the filter core of the application is used, hydraulic oil enters the filter, is located at the outside of the filter core, and flows from one side of the mounting seat 2 to one side of the bypass valve 4, when the hydraulic oil passes through the mounting seat 2, the first magnet 51 adsorbs the iron filings in the hydraulic oil, then the hydraulic oil enters the inside of the filter core through the filter screen, and then is output, the first magnet 51 adsorbs the iron filings, prolongs the period of the filter screen being blocked, and further prolongs the service life of the filter core; when the flow rate of the filter screen decreases and the bypass valve 4 is opened, part of the hydraulic oil enters the inside of the filter core through the bypass hole 3, at this time, the second magnet 52 adsorbs the hydraulic oil flowing into the bypass hole 3 again, so that the hydraulic oil entering the filter core through the bypass hole 3 is cleaner, and the service life of the hydraulic equipment is further prolonged.

[0017] Specifically, the second magnet 52 and the bypass hole 3 have the interval 6 therebetween, so that the iron filings adsorbed by the second magnet 52 are far away from the bypass hole 3, contact between the bypass valve 4 and the iron filings during operation is avoided, and further, the iron filings entering the inside of the filter core through the bypass hole 3 is avoided, and the stability during use is improved.

[0018] As an improved specific implementation, the interval area 6 is provided with a support frame 61, and the support frame 61 is provided with a third magnet 53, the position of the third magnet 53 being offset from the position of the second magnet 52.

[0019] Through the above technical solution, a support frame 61 is set on the interval area 6, and a third magnet 53 is set on the support frame 61. There is a sufficient gap between the third magnet 53 and the filter element for hydraulic oil to flow. Furthermore, the third magnet 53 cooperates with the second magnet 52 to adsorb iron filings in the hydraulic oil passing through the bypass hole 3 when the bypass valve 4 is opened. The adsorption is more thorough, thereby better protecting the hydraulic equipment.

[0020] As an improved specific implementation, the support frame 61 is provided with baffles 62, and there is a passage space 63 between adjacent baffles 62, and the baffles 62 are arranged in an arc shape.

[0021] By using the above technical solution, a baffle 62 is set to block the flow of iron filings adsorbed on the second magnet 52, preventing them from entering the hydraulic equipment through the bypass hole 3, thus providing better protection.

[0022] Specifically, the baffle 62 is arc-shaped, which reduces flow resistance and ensures the flow rate of hydraulic oil as it passes through the passage space 63 and enters the bypass hole 3.

[0023] As an improved specific implementation, the baffle 62 is provided with a fourth magnet 54, which is arranged in an arc shape.

[0024] Through the above technical solution, the fourth magnet 54, together with the third magnet 53 and the second magnet 52, can more thoroughly adsorb iron filings in the hydraulic oil passing through the bypass hole 3, and can better protect the hydraulic equipment.

[0025] As an improved specific embodiment, the mounting base 2 is provided with a mounting groove 71, and the first magnet 51 is disposed in the mounting groove 71. The first magnet 51 is located in the middle of the mounting groove 71. There is an upper gap 72 between the first magnet 51 and the upper side of the mounting groove 71, and a lower gap 73 between the first magnet 51 and the lower side of the mounting groove 71. An upper positioning rod 721 is provided in the upper gap 72, and the upper positioning rod 721 abuts against the upper end face of the mounting groove 71 and the upper end face of the first magnet 51. A lower positioning rod 731 is provided in the lower gap 73, and the lower positioning rod 731 abuts against the lower end face of the mounting groove 71 and the lower end face of the first magnet 51.

[0026] By using the above technical solution, the installation groove 71 is set up, and the first magnet 51 is placed in the middle of the installation groove 71, which expands the magnet's adsorption area and can better adsorb iron filings in the hydraulic oil. Furthermore, the adsorbed iron filings can enter the upper gap 72 and the lower gap 73, reducing the impact on the flow resistance of the hydraulic oil and thus extending the service life of the filter element.

[0027] As one specific implementation of the improvement, the upper positioning rod 721 and the lower positioning rod 731 are staggered.

[0028] Through the above technical solution, the upper positioning rod 721 and the lower positioning rod 731 are staggered, so that the first magnet 51 has no dead angle in the process of adsorbing iron filings, and can better adsorb iron filings in hydraulic oil.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model.
