In order to better adapt to rust-proof oil containers of different specifications, the mechanism is specially equipped with a retractable part; in addition, in order to avoid clogging of the filter screen 105 during the suction filtration process, the primary suction filter mechanism 1 is also provided with a filter screen 105 that can vibrate during suction filtration.

[0029] The working principle of this embodiment is as follows: when the device for purifying trace flocculent solids in rust-proof oil is used, the left end of the inner tube 102 is placed in the rust-proof oil container, the first motor 109 is started to rotate to drive the impeller 110 to rotate, the rust-proof oil is filtered through the filter 105 and sucked into the inner tube 102, while being sucked, the rust-proof oil pushes the cam 107 to polarize, causing the filter 105 to vibrate, and the flocculent solids adsorbed on the filter 105 in the rust-proof oil are vibrated and broken, the sealing ring 111 makes the inner tube 102 fit tightly with the outer tube 101, and the filtered rust-proof oil enters the turbine flow meter 2 through the bend pipe and enters the first box body 5, and is discharged from the discharge pipe 4.

[0030] Example 2: Please refer to Figure 4-Figure 5 On the basis of the first embodiment, the present invention provides a technical solution: the filter replacement mechanism 3 includes a filter barrel 301, the left side of the filter barrel 301 is fixedly connected to the top of the turbine flow meter 2 through a bend pipe, the outer surface of the filter barrel 301 is fixedly connected to a first connecting block 302, the right side of the first connecting block 302 is fixedly connected to a first hydraulic pump 303, the output end of the first hydraulic pump 303 is fixedly connected to a second connecting block 304, the interior of the first box body 5 is fixedly connected to a fixed block 310, the interior of the fixed block 310 is fixedly connected to a second motor 311, the output end of the second motor 311 is fixedly connected to a connecting rod 312, and the outer surface of the connecting rod 312 is fixedly connected A filter assembly 3001 is provided, the filter assembly 3001 includes a through-hole column 305, the through-hole column 305 is fixedly connected to the outer surface of a connecting rod 312, a first card slot 306 is provided inside the through-hole column 305, a first card block 307 is clamped inside the first card slot 306, a filter element 308 is fixedly connected to the inner surface of the first card block 307, a card slot is provided inside the through-hole column 305 and a rubber card block 309 is fixedly connected to the inner spring, a third connecting block 314 is fixedly connected to the bottom of the filter barrel 301, a flow sensor 315 is clamped inside the third connecting block 314 through a card slot, and an electromagnetic coupling 313 is fixedly connected to the right side of the connecting rod 312; A group of filter components 3001 are rotatably provided on the outer surface of the connecting rod 312 and are in contact with the outer surface of the through-hole column 305. A support block is provided on the outer surface of the first hydraulic pump 303 and is fixedly connected to the filter barrel 301. The filter replacement mechanism 3 is provided with three groups inside the first box body 5. By setting the filter replacement mechanism 3, the material is filtered through the filter element 308. Firstly, with its multi-stage filtration design, the rust-proof oil can be finely filtered layer by layer; the filter replacement mechanism 3 can replace different filter elements 308, which improves the adaptability to different rust-proof oils, and the best filtering effect is achieved by replacing the corresponding filter element 308; it not only improves the adaptability to different rust-proof oils, but also greatly improves the purification efficiency.

[0031] The working principle of this embodiment is as follows: the above-mentioned filtering process needs to be supplemented to improve the filtering efficiency and accuracy. The anti-rust oil passes through the turbine flow meter 2 and enters the filter barrel 301. The anti-rust oil is filtered by the multi-stage filter element 308 and discharged from the discharge pipe 4. At this time, the flow sensor 315 performs flow monitoring and is compared with the turbine flow meter 2. After a significant change occurs, the second motor 311 starts to rotate, driving the filter component 3001 and the filter component 3001 rotatably arranged on the outer surface of the connecting rod 312 to rotate so that the filter component 3001 rotates away from the filter barrel 301 and the rotating filter component 3001 enters the filter barrel 301, thereby realizing the replacement of the filter element 308. The support block on the lower surface of the first hydraulic pump 303 is connected to the filter barrel 301 to stabilize its position. When the symmetrically arranged flow sensor 315 performs flow monitoring and is connected to the symmetrically arranged filter component 3001, the electromagnetic coupling 313 controls the connection of the connecting rod 312, and the second motor 311 starts to rotate to realize the above-mentioned movement process, so that the multi-stage filtration filter element 308 can be replaced.

[0032] Example 3: Please refer to Figure 6-Figure 8On the basis of the first and second embodiments, the present invention provides a technical solution: the automatic replacement mechanism 6 includes a waste box 601, the waste box 601 is fixedly connected to the bottom of the first box body 5, a waste slot 602 is provided at the bottom of the first box body 5, a feed slot 603 is provided at the top of the first box body 5, a first rectangular column 604 is fixedly connected inside the first box body 5, a second hydraulic pump 605 is fixedly connected to the left side of the first rectangular column 604, a second card slot 606 is fixedly connected to the bottom of the first box body 5, and a stopper 609 is fixedly connected to the side of the second card slot 606, The right side of the stopper 609 is fixedly connected with a third slot 608, the outer surface of the second slot 606 is connected with a sensor 607 by opening a through slot, the inside of the third slot 608 is fixedly connected with a lead screw 610, the outer surface of the lead screw 610 is threadedly connected with a slider 611, the outer surface of the slider 611 is connected with a fourth connecting block 612 by opening a slot, the top of the fourth connecting block 612 is rotatably connected with a hinge group 613 by opening a through hole, the top of the hinge group 613 is fixedly connected with a third motor 614, and the output end of the third motor 614 is fixedly connected with an electromagnet 615; The waste trough 602 and the feed trough 603 are both the same length as the filter element 308 and are arranged relative to each other. The notch of the second slot 606 and the notch of the feed trough 603 are in the same position in the vertical direction. The shape of the sensor 607 is the same as that of the first block 307. The hinge group 613 is in the extreme position and can only be compressed but not stretched. By setting up an automatic replacement mechanism 6, which cooperates with the filter replacement mechanism 3, the filter element 308 can be replaced, which greatly improves work efficiency and reduces the need for manual intervention. In addition, the automatic replacement mechanism 6 also realizes the rapid replacement of the filter element 308 and the disposal of the discarded filter element 308, ensuring that the filter element 308 can efficiently filter the anti-rust oil and ensure that the quality of the purified anti-rust oil always meets the requirements.

[0033] The working principle of this embodiment is as follows: when replacing the filter element 308, some manual work is required, which is assisted by the automatic replacement mechanism 6. When the filter assembly 3001 moves to the extreme position, the symmetrically arranged second hydraulic pump 605 pushes the discarded filter element 308 to move, and enters the waste box 601 through the second slot 606 and the third slot 608. At this time, the lead screw 610 rotates through the thread to drive the slider 611, the fourth connecting block 612 and the third motor 614 to move, driving the filter element in the second slot 606 to move. The electromagnet 615 on the surface of 606 moves, and drives the new filter element 308 adsorbed by the electromagnet 615 to move downward. When the bottom of the fourth connecting block 612 contacts the stopper 609, the hinge assembly 613 is pressed and gradually pushes the third motor 614 to move rightward, and the new filter element 308 is pushed by the electromagnet 615. If the position of the new filter element 308 does not match the first card slot 306, the sensor 607 senses the gap between the first card slot 306 and the second card slot 606, and the third motor 614 rotates through the electromagnet 615. The new filter element 308 is driven to rotate. When the sensor 607 senses the gap to the minimum limit, the third motor 614 stops rotating. The new filter element 308 cooperates with the first slot 306 and is pushed at this time. When the whole is pushed into the through-hole column 305, it is blocked by the rubber block 309. At this time, the sensor 607 senses a specific spacing, and the screw 610 stops rotating. The replacement of the filter element 308 is completed. If the filter element 308 is used up, it is replaced again through the above-mentioned replacement process, and the new filter element 308 is placed through the feed trough 603.
