[0026] like Figure 1-4 As shown, the utility model provides an emulsion magnetic filter, including a shell 1, a liquid inlet 2 is provided at one end of the shell 1, a liquid outlet 3 is provided at the other end, a flow channel 4 is provided in the shell 1, three magnetic rods 5 are vertically provided on the shell 1 along the extension direction of the flow channel 4, a push rod 6 is provided at the top of the magnetic rod 5, and the push rod 6 extends out of the shell 1, and a circular hole 7 is provided at the bottom of the shell 1 corresponding to each magnetic rod 5, a connecting sleeve 8 is provided outside the circular hole 7, a collecting cylinder 9 is threadedly connected to the connecting sleeve 8, and a scraper ring 10 is provided inside the collecting cylinder 9. A support frame 11 is provided at the bottom of the shell 1.

[0027] In order to ensure sufficient contact between the emulsion and the magnetic rod 5 and maintain a stable flow rate, in this embodiment, the shell 1 includes a horizontal section 1-1 and three longitudinally arranged cylindrical sections 1-2. The three cylindrical sections 1-2 are evenly arranged in a straight line on the horizontal section 1-1 and are connected to the horizontal section 1-1. The magnetic rod 5 is arranged in the middle of the cylindrical section 1-2.

[0028] In order to enable the periphery of the magnetic rod 5 to fully absorb impurities and debris, in this embodiment, a driving mechanism is provided at the top of the push rod 6, and the driving mechanism includes a mounting bracket 12, and a driving motor 13 is provided at the top of the mounting bracket 12. The output end of the driving motor 13 is connected to the top of the push rod 6, and the mounting bracket 12 is connected to the top of the housing 1 through a telescopic rod 14. In this embodiment, the telescopic rod 14 is an electrically controlled telescopic rod.

[0029] In this embodiment, the inner diameter of the scraper ring 10 matches the outer diameter of the magnetic rod 5, the outer surface of the magnetic rod 5 is in close contact with the inner surface of the scraper ring 10, the inner diameter of the circular hole 7 is larger than the outer diameter of the magnetic rod 5, and the inner diameter of the connecting sleeve 8 is larger than the inner diameter of the circular hole 7.

[0030] In order to ensure that the emulsion in the housing 1 does not leak when the collecting cylinder 9 is removed for cleaning and replacement, in this embodiment, a one-way valve 15 is provided in the connecting sleeve 8 .

[0031] The working principle of the above technical solution is:

[0032] When in use, the emulsion flows from the liquid inlet 2 in the flow channel 4 in the shell 1 and contacts the three magnetic rods 5. The magnetic rods 5 adsorb the impurities and debris that can be magnetically adsorbed mixed in the emulsion on their surfaces to remove impurities. The magnetic rods 5 rotate axially under the drive of the drive motor 13. After working for a period of time, each magnetic rod 5 needs to be cleaned to maintain its optimal adsorption effect. The operating steps are to control the telescopic rod 14 to contract so that the magnetic rod 5 moves downward, and the outer surface of the magnetic rod 5 contacts the inner side of the top of the scraper ring 10, and the debris adsorbed on the surface of the magnetic rod 5 is scraped into the collection tube 9, and then the telescopic rod 14 is controlled to reset. Finally, remove the collection tube 9 to pour out the emulsion and debris for cleaning.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The emulsion of the utility model continuously flows in the housing 1, which can ensure its continuous use, and the magnetic rod 5 of the utility model can be cleaned without stopping use, thereby improving work efficiency. Embodiment 2

[0036] In order to allow the removed debris to be adsorbed onto the magnetic rod 5 again, in this embodiment, a filter cartridge 16 is threadedly connected to the bottom of the scraper ring 10 .

[0037] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
