[0016] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0017] like Figure 1-5 The high-viscosity media electromagnetic filtration system shown includes a filter 3 and a filter element 4 located inside the filter 3.

[0018] The filter 3 is connected to an inlet pipe 31 at its upper end and an outlet pipe 32 at its lower end. Solenoid valves 7 are installed on both the inlet pipe 31 and the outlet pipe 32. High-viscosity media enters the filter 3 through the inlet pipe 31, and the filtered high-viscosity media is discharged from the outlet pipe 32.

[0019] The filter element 4 includes a frame 41 and multiple layers of flower-shaped magnetically conductive filter elements 42 mounted on the frame 41, with gaps between adjacent flower-shaped magnetically conductive filter elements 42. By setting multiple layers of flower-shaped magnetically conductive filter elements 42, not only is the flow of magnetic field guaranteed, but the flow of high-viscosity media can also be effectively guaranteed, reducing filtration resistance and improving filtration accuracy.

[0020] The flower-shaped magnetic filter element 42 includes several stainless steel rings 421 nested sequentially and stainless steel corrugated plates 422 connecting adjacent stainless steel rings 421. The use of stainless steel gives the flower-shaped magnetic filter element 42 not only excellent magnetic permeability but also good corrosion resistance. The flower-shaped magnetic filter element 42 has a large filtration area, facilitating efficient adsorption of magnetic particles in high-viscosity media. The use of stainless steel corrugated plates 422 allows for a greater increase in the magnetic permeability of the filter element 4 while ensuring the flow of high-viscosity media.

[0021] The frame 41, stainless steel ring 421 and stainless steel corrugated plate 433 are connected by welding, and the connection is strong.

[0022] It also includes an electromagnetic coil 2 enclosed outside the filter 3. The electromagnetic coil 2 is made of tightly wound copper wire with good insulation properties, which can maximize the magnetic field strength. It also includes a control cabinet 6, which contains a power supply and a variable resistor. The power supply, variable resistor, and electromagnetic coil 2 form an electrical circuit. The electromagnetic coil 2 has a certain magnetic field strength, making the flower-shaped magnetic filter element 42 magnetic, thus facilitating the adsorption of magnetic particles in high-viscosity media. Furthermore, the magnetic field strength of the electromagnetic coil 2 can be adjusted as needed. A high magnetic field strength results in low filtration resistance, which can meet the requirements for removing magnetic particles from media with a viscosity of 8000 cp or higher. The enhanced magnetic field strength can reach up to 20000 GS, which can remove magnetic particles larger than 5μm, with a filtration efficiency exceeding 90%.

[0023] It also includes a sealed housing 1, within which the electromagnetic coil 2 is located, and the sealed housing 1 is filled with working oil. The sealed housing 1 is also externally connected to an oil temperature gauge 9 for real-time monitoring of the working oil temperature. It also includes a plate heat exchanger 5, which is connected to the sealed housing 1 via oil pipes and is used to reduce the working oil temperature of the electromagnetic coil 2.

[0024] It also includes a bracket 8, on which the filter 3, the sealed housing 1, the control cabinet 6 and the plate heat exchanger 5 are all mounted.

[0025] The working process of the high-viscosity medium electromagnetic filtration system is as follows: The high-viscosity medium enters the filter 3 through the inlet pipe 31. The electromagnetic coil 2 is energized and has a certain magnetic field strength. The flower-shaped magnetic filter element 42 has magnetic properties and adsorbs magnetic particles in the high-viscosity medium. The filtered high-viscosity medium is discharged from the outlet pipe 32. At the same time, the plate heat exchanger 5 works to reduce the working oil temperature of the electromagnetic coil 2.
