Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic oil filters, and particularly relates to a high-efficiency magnetic hydraulic oil filter. Background Art

[0002] Since there are often various impurities of different sizes in the hydraulic system, especially particles with a diameter less than 10 microns, these tiny particles usually escape the adsorption of the magnetic filter, resulting in ineffective removal, thus affecting the performance and stability of the hydraulic system. The generation of these drawbacks is closely related to the design and material properties of the magnetic filter. At present, the magnetic materials used in many magnetic hydraulic oil filters have limitations in adsorption force and endurance, and are prone to weakening magnetism under the influence of the magnetic field or high temperature during long-term hydraulic oil flow.

[0003] Conventional countermeasures include increasing the size of the magnet of the filter, increasing the filtering area of the filter, and combining mechanical filtration with magnetic filtration. Although increasing the magnet size can enhance its adsorption capacity, it may also lead to a large design volume, increased weight, and affect the system layout. Therefore, we hope to design a hydraulic oil filter with a new structure to solve this problem. Summary of the Utility Model

[0025] Please refer to Figures 1 to 3 , an oil passage 141 is provided inside the front side of the lower end of the filter body 100. The front end of the oil passage 141 is communicated with the inlet 140. A discharge port 110 is provided at the rear side of the lower end of the filter body 100, and a discharge cavity 111 is provided inside the rear side of the lower end of the filter body 100. The rear end of the discharge cavity 111 is communicated with the discharge port 110.

[0026] A hydraulic sensor 120 is installed on the right side of the filter body 100. An installation hole is provided on the inner wall of the right side of the inlet 140. The inner part of the hydraulic sensor 120 extends to the inlet 140 through the installation hole. The hydraulic sensor 120 can adopt an existing product model in the market. The setting of the hydraulic sensor 120 can monitor the hydraulic pressure inside the filter body 100. If there is a large change, it means that cleaning is required.

[0027] The axis of the vertical pipe 150 is collinear with the axis of the cylinder body 130. The inclination angle of the inclined pipe 160 is 70 degrees, and the upper end height of the inclined pipe 160 is flush with the lower one-third height of the cylinder body 130.

[0028] As the first embodiment of the present utility model, by arranging the vertical pipe 150 and the inclined pipe 160 at the bottom of the filter body 100, in actual use, since the inclination angle of the inclined pipe 160 is 70 degrees and the upper end height of the inclined pipe 160 is flush with the lower one-third height of the cylinder body 130, the hydraulic oil sprayed from the inclined pipe 160 will spray onto the inner wall of the front side of the cylinder body 130 and flow backward to the middle part of the top of the cylinder body 130, and then move to the lower rear side of the cylinder body 130 under the reverse flow action at the top of the cylinder body 130, and finally enter the discharge cavity 111 and be discharged through the discharge port 110, so that the entering hydraulic oil comes into contact with the first magnetic rod 260 and the second magnetic rod 270 to a large extent, expanding the magnetic adsorption contact area, and thus helping the first magnetic rod 260 and the second magnetic rod 270 to perform magnetic adsorption filtration efficiently.

[0029] Please refer to Figure 3 , the middle of the upper end of the ferrule 220 is threadedly connected to the outer wall of the lower end of the fixing cap 210.

[0030] The upper sides of the first magnetic rod 260 and the second magnetic rod 270 are both slidably and hermetically connected to the top end of the cylinder body 130. The length of the first magnetic rod 260 is greater than the length of the second magnetic rod 270, and the lower end of the second magnetic rod 270 does not directly contact the upper end of the inclined pipe 160. The first magnetic rod 260 and the second magnetic rod 270 are both a kind of strong magnetic rods, which can quickly adsorb tiny iron particles in the hydraulic oil and improve the magnetic filtration effect.

[0031] As the second embodiment of the present utility model, the ferrule 220 is movably sleeved on the upper side of the cylinder body 130, and both the first magnetic rod 260 and the second magnetic rod 270 are slidably sealed and connected to the top of the cylinder body 130. This enables the entire magnetic attraction assembly 200 to be quickly disassembled when necessary, and the disassembly method is very simple. Just pull up the handle 230 to separate the entire magnetic attraction assembly 200 from the cylinder body 130. When necessary, the iron impurities adsorbed on the first magnetic rod 260 and the second magnetic rod 270 can be detached by lifting the magnetic attraction and relying on the top of the cylinder body 130, so as to achieve the purpose of quickly cleaning the first magnetic rod 260 and the second magnetic rod 270. The arrangement of multiple first magnetic rods 260 and second magnetic rods 270 can more efficiently magnetically filter the iron impurities in the hydraulic oil, thereby improving the magnetic filtering ability of the entire device.
