[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figures 1 to 4 This utility model provides a dual-function filter element for oil-water separation and impurity filtration, comprising a housing 1, a partition plate 2 inside the housing 1, a filter chamber 3, a separation chamber 4, and a sedimentation chamber 5 inside the housing 1, a coarse filter layer 6 and a fine filter layer 7 inside the filter chamber 3, multiple radial guide plates 8 inside the filter chamber 3, a filter element 9 inside the separation chamber 4, a top cover 10 fixedly connected to the upper end of the housing 1, an oil inlet pipe 11 and an oil outlet pipe 12 fixedly connected to the upper end of the top cover 10, and a drain bolt 13 at the bottom end of the sedimentation chamber 5, which is threadedly connected to the bottom of the housing 1.

[0024] The oil inlet pipe 11 is connected to the filter chamber 3. The edge of the guide plate 8 is fixedly connected to the inner surface of the housing 1 and the partition plate 2. The guide plate 8 divides the filter layer into multiple independent filter channels. Because the liquid flows in a spiral shape in the filter channel, the contact time and area between the oil and the filter layer are increased, thus improving the filtration effect.

[0025] The separation chamber 4 is equipped with a cylinder 14. The upper end of the cylinder 14 is fixedly connected to the top cover 10. The oil outlet pipe 12 is connected to the cylinder 14. The filter element 9 is located inside the cylinder 14. The filter element 9 is made of polystyrene, an oleophilic and hydrophobic material. The lower end of the cylinder 14 is provided with a liquid inlet 15.

[0026] The fine filter layer 7 includes a pre-filter layer 701, an adsorption filter layer 702, and a fine filter layer 703. The pre-filter layer 701 is made of polypropylene fiber, the adsorption filter layer 702 is made of a mixture of glass fiber and activated carbon, and the fine filter layer 703 is made of high-precision filter paper folded together.

[0027] The coarse filter layer 6 is located at the top of the guide plate 8, the fine filter layer 7 is located in the middle of the guide plate 8, the lower end of the filter chamber 3 is provided with a coalescence separation layer 16, the coalescence separation layer 16 is located above the sedimentation chamber 5, the coalescence separation layer 16 is located at the bottom of the guide plate 8, and the top cover 10 and the drain bolt 13 are provided with sealing rings 17 at their circumferential edges.

[0028] Working principle: During use, the oil-water mixture enters the filter chamber 3 through the oil inlet pipe 11. The liquid then flows through the coarse filter layer 6 to the guide plate 8, where larger impurities (such as stones, wood chips, etc.) are blocked. Next, the liquid flows from the guide plate 8 through the fine filter layer 7. The primary filter layer 701 filters larger particulate impurities, the glass fiber in the adsorption filter layer 702 filters smaller particulate impurities, and the activated carbon adsorbs odors and some organic impurities in the oil. The fine filter layer 703 filters out micro-particles in the liquid. Small particulate impurities are then passed through the coalescence separation layer 16. The filter layer in the coalescence separation layer 16 can cause the tiny water droplets in the oil to coalesce into larger water droplets. Then the liquid flows into the sedimentation chamber 5 and then rises into the separation chamber 4. Since the density of oil is less than that of water, most of the water sinks into the sedimentation chamber 5. Then the liquid enters the inlet 15 and enters the filter element 9. Since the filter element 9 has oleophilic and hydrophobic properties, the oil in the liquid can pass through easily, while the remaining tiny water droplets are blocked. The separated oil flows out from the oil outlet pipe 12.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
