Its function is to filter out the pollutants generated or invaded in the system before returning to the oil tank. In the steel industry, the return oil filter is usually used in the hydraulic station system of the continuous casting machine. The hydraulic station system of the continuous casting machine ensures the continuity and stability of production. Steel manufacturers pay special attention to the use and maintenance of the hydraulic station system of the continuous casting machine.

[0003] Metal particles generated by wear and tear of running equipment enter the hydraulic station system along with the oil, which can easily cause failures of other equipment. In order to enhance the barrier capacity of the return oil filter to metal particles, magnetic return oil filters are currently commonly used. The filter element of the magnetic return oil filter is magnetic and can absorb metal particles. However, metal particles are easily accumulated at the bottom of the shell, causing blockage of the oil holes, and metal particles are scattered on the filter element, which is not conducive to the cleaning of the return oil filter by the staff. In view of the above phenomenon, in order to reduce the blockage of the oil holes of the return oil filter and facilitate the cleaning of the return oil filter by the staff, the inventor invented a new type of combined magnetic return oil filter.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-3 The utility model is described in further detail.

[0025] The utility model discloses a combined magnetic oil return filter.

[0026] Reference Figure 2 and Figure 3The bracket 21 includes an annular tube 211 and a frame plate 212, the frame plate 212 is slidably connected to the inner wall of the annular tube 211 in the vertical direction, the frame plate 212 is provided with a filter groove 2121, and the oil hole 23 is provided on the frame plate 212, that is, the oil hole 23 is connected with the filter groove 2121, the magnetic rod 22 is movably installed on the filter groove 2121, and when the cover plate 14 is installed, the top end of the frame plate 212 abuts against the bottom surface of the cover plate 14; a placing table 15 is provided inside the shell 1, and the bottom end of the annular tube 211 abuts against the upper surface of the placing table 15; that is, the bracket 21 is in a state of being clamped by the placing table 15 and the cover plate 14, so that the bracket 21 can be kept in a fixed state. If the bracket 21 is cleaned in advance, the cover plate 14 can be opened and the bracket 21 can be directly removed. A vertical slide groove 2111 is provided on the circumferential inner wall of the annular cylinder 211, and multiple groups of slide grooves 2111 are arranged. In this embodiment, four groups of slide grooves 2111 are optimally arranged. The four groups of slide grooves 2111 are arranged in a circular array on the circumferential inner wall of the annular cylinder 211. The circumferential side wall of the frame plate 212 is provided with a slider 2122 slidably connected to the slide groove 2111. When the bracket 21 is cleaned in advance, the frame plate 212 can be slid to the top of the annular cylinder 211, thereby reducing the distance from the bottom of the filter trough 2121 to the top of the annular cylinder 211, making it convenient for the staff to clean the filter trough 2121. The arrangement of the slide groove 2111 and the slider 2122 enhances the stability of the frame plate 212 when sliding.

[0027] Reference Figure 3 The frame plate 212 is provided with a rod hole 2123 for installing the magnetic rod 22. The rod hole 2123 is connected to the filter tank 2121. The magnetic rod 22 is slidably connected to the rod hole 2123. The bottom end of the frame plate 212 is fixedly connected with a spring 2124 sleeved on the magnetic rod 22. The end of the spring 2124 away from the frame plate 212 is fixedly connected to the bottom end of the magnetic rod 22. When the magnetic metal adsorbed on the magnetic rod 22 is to be cleared, the magnetic rod 22 can be slid in the vertical downward direction. At this time, the magnetic metal adsorbed on the magnetic rod 22 cannot pass through the rod hole 2123 and falls into the filter tank 2121, thereby facilitating the staff's cleaning work of the magnetic rod 22. Under the action of the spring 2124, the magnetic rod 22 can be restored to its initial state after cleaning.

[0028] Reference Figure 2 and Figure 3The filter slot 2121 is provided with a guide cylinder 24, and the guide cylinder 24 is sleeved on the magnetic rod 22. The setting of the guide cylinder 24 ensures the stability of the magnetic rod 22 in the sliding state, so that the magnetic rod 22 is not easy to tilt. On the other hand, the magnetic metal adsorbed on the magnetic rod 22 cannot pass through the guide cylinder 24, and the guide cylinder 24 plays a role of scraping off the magnetic metal on the magnetic rod 22. The slot surface of the filter slot 2121 is provided with a thread groove 2125, and the bottom end of the guide cylinder 24 is threadedly connected in the thread groove 2125. When the amount of magnetic metal adsorbed on the magnetic rod 22 is small, there is no need to slide the magnetic rod 22, and the guide cylinder 24 can only be rotated and slid, so that the guide cylinder 24 is separated from the thread groove 2125 and slides on the magnetic rod 22, and the guide cylinder 24 plays a role of scraping off the magnetic metal adsorbed on the magnetic rod 22. The magnetic rod 22 is in a state of being in contact with the guide cylinder 24 and the circumferential inner wall of the rod hole 2123, respectively, thereby reducing the phenomenon of magnetic metal leaking to the filter element 13.

[0029] The implementation principle of a combined magnetic oil return filter in the embodiment of the utility model is as follows:

[0030] By arranging a magnetic attraction component 2 inside the housing 1, the magnetic attraction component 2 is arranged below the oil inlet 11, and the magnetic attraction component 2 includes a bracket 21 and a magnetic rod 22. The oil entering the housing 1 from the oil inlet 11 first passes through the magnetic attraction component 2, and the magnetic rod 22 adsorbs the magnetic metal in the oil. The oil adsorbed by the magnetic rod 22 enters the filter element 13 through the oil hole 23, thereby reducing the clogging of the filter element 13 by the magnetic metal; the bracket 21 includes a ring tube 211 and a frame plate 212, and the cover plate 14 is installed In the installed state, the cover plate 14 is in abutment with the bracket 21, and the ring tube 211 is in abutment with the placement table 15. The cover plate 14 is disassembled, and the staff can directly remove the magnetic suction component 2, which is convenient for the staff to disassemble and assemble the magnetic suction component 2. The magnetic rod 22 is slidably connected in the rod hole 2123. The sliding magnetic rod 22 makes the magnetic metal adsorbed on the magnetic rod 22 unable to pass through the guide tube 24 and the rod hole 2123. The guide tube 24 and the rod hole 2123 both play a role in scraping off the magnetic metal adsorbed on the magnetic rod 22. The combined magnetic return oil filter in this application has a simple structure and is easy to disassemble and assemble. It not only has a good filtering effect on magnetic metals, but also facilitates the disassembly and cleaning work of the staff.
