BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of the utility model (two filter components);

[0015] Figure 2 yes Figure 1 The structural diagram of the filter component;

[0016] Figure 3 This is another structural schematic diagram of the utility model (three filter components). DETAILED DESCRIPTION

[0017] Combine the following Figures 1 to 3 The technical solution of the utility model is further illustrated by specific embodiments.

[0018] like Figure 1 The multi-stage impurity filtering device for mixture purification shown includes: a cylinder 1, a cover plate 2, a pressure plate 5, an adjusting screw 4 and a filtering assembly 8. The cover plate 2 is arranged on the top of the cylinder 1. In this embodiment, the cover plate 2 is provided with a fastening screw 3 connected to the cylinder 1 to fix the cover plate 2 and facilitate disassembly and assembly.

[0019] Several filter assemblies 8 are stacked up and down in the cylinder 1, and multiple impurities are filtered through the filter assemblies 8. The filter hole diameter of the upper filter assembly is larger than the filter hole diameter of the lower filter assembly, and the liquid mixture is gradually purified to reduce the flow resistance. Figure 1 and Figure 3 As shown, the filtration level can be improved by increasing the number of filter components 8, which is flexible to adjust and has good adaptability to multiple filtration requirements, and the height of a single filter component 8 can be increased or reduced to meet the needs of fixation in the cylinder 1.

[0020] like Figure 1As shown, the pressing plate 5 is floatingly arranged in the cylinder 1 and is located above the filter assembly 8. In this embodiment, the pressing plate 5 adopts a disc structure, and the outer diameter of the pressing plate 5 corresponds to the inner diameter of the cylinder 1 to guide the lifting of the pressing plate 5. A first sealing ring 9 is arranged on the outer circle of the pressing plate 5, and the outer circle of the pressing plate 5 is sealed by the first sealing ring 9 to avoid leakage.

[0021] The bottom of the pressing plate 5 is provided with a pressing rod 7 pointing to the filter assembly 8 downward to press and fix the filter assembly 8. In this embodiment, the adjusting screw 4 is provided on the cover plate 2 and extends downward to the top of the pressing plate 5 to press and fix the pressing plate 5. The cover plate 2 is provided with a threaded hole corresponding to the adjusting screw 4, which is convenient for rotating the adjusting screw 4 to adapt to filter assemblies 8 of different numbers or different heights, and the adjustment is convenient.

[0022] A liquid inlet pipe joint 6 is provided on one side of the cylinder 1 and is located between the pressure plate 5 and the filter assembly 8. The liquid inlet pipe joint 6 is externally connected to a liquid inlet pipe to introduce the liquid mixture into the cylinder 1 and filter and purify it using the filter assembly 8. A liquid outlet pipe joint 10 is provided at the bottom of the cylinder 1 and is externally connected to a liquid outlet pipe through the liquid outlet pipe joint 10 to discharge the purified liquid mixture.

[0023] like Figure 2 As shown, the filter assembly 8 comprises a positioning ring 83, a cylindrical filter screen 84 and a support body 81. The cylindrical filter screen 84 is arranged in the positioning ring 83 and extends downward to filter the liquid mixture. The support body 81 is arranged at the bottom of the positioning ring 83 and extends downward to the outside and below of the cylindrical filter screen 84. The support body 81 contacts the filter assembly or the bottom of the cylinder 1 below it to protect the cylindrical filter screen 84 and avoid the problem of the cylindrical filter screen 84 being squeezed.

[0024] In this embodiment, the support body 81 adopts a cylindrical structure, and the outer diameter of the support body 81 corresponds to the inner diameter of the cylinder 1, and the structure is stable. A second sealing ring 82 is arranged on the outer circle of the positioning ring 83 to prevent the positioning ring 83 from preventing the unfiltered liquid mixture from flowing downward through the gap between the outer circle of the positioning ring 83 and the inner wall of the cylinder 1, thereby ensuring the filtering and purification accuracy of the liquid mixture.
