Therefore, effective filtration of the crude oil to remove impurities is an important link in oil processing. Crude oil refers to the primary oil that is prepared from animal or vegetable oil materials and is not refined, and contains water, mechanical impurities, colloid and other impurities. The existence of these impurities makes the crude oil easy to oxidize and deteriorate, and is not suitable for long-term storage. Therefore, effective filtration of the crude oil to remove impurities is an important link in oil processing.

[0042] Closed chain 80: including gears connected to each gear shaft 70;

[0043] Arc plate 90: a plurality of arc plates 90 are fixed on the closed chain 80 in sequence.

[0044] According to the multi-layer drum type crude oil filter of the embodiment of the utility model, at least has following beneficial effect:

[0045] Improve the filtering efficiency: by arranging the fine mesh screen surface with 150-200 meshes per inch on the side surface of the oil filter cylinder 30, the solid suspended matter in the crude oil can be effectively intercepted, so that the filtering efficiency of the crude oil is improved, and the quality of the filtered oil is ensured.

[0046] Continuous operation ability: the filter is designed in a continuous operation mode, the crude oil enters the box 10 through the oil inlet pipe, after being filtered, the clean oil is discharged through the clean oil outlet pipe 50 in the center shaft 40, and the solid impurities are deposited in the sedimentation tank 12, realizing the continuous operation of filtering and deslagging, and improving the production efficiency.

[0047] Compact structure, simple operation: the box 10 is designed compactly, the lower inclined surface 11 directly extends to the sedimentation tank 12, simplifying the structure and facilitating installation and maintenance. At the same time, only the inlet and outlet of the crude oil need to be controlled through the valve during the operation process, so that the operation is simple and the labor cost is reduced.

[0048] Automatic cleaning function: the series of slits on the side surface of the oil flushing pipe 60 can flush the screen surface of the oil filter cylinder 30 when the crude oil enters the box 10, reducing the risk of filter screen blockage and prolonging the service life of the filter screen.

[0049] Innovative design of spiral purification assembly 310: the spiral purification assembly 310 fixedly installed on the center shaft 40 further purifies the oil through the purification holes thereon, improves the filtering precision, and the spiral structure helps to promote the flow of oil, enhancing the filtering effect.

[0050] Effective slag removal mechanism: by fixing gear shaft 70 at both ends of the groove and at both ends of the deposition pool 12, and connecting the closed chain 80 and the arc plate 90, an effective slag removal mechanism is formed. The arc plate 90 continuously removes the slag deposited in the deposition pool 12 with the rotation of the gear shaft 70, avoiding the tediousness and unhygienic of manual cleaning.

[0051] According to some embodiments of the present application, the screen surface and the spiral purification assembly 310 are made of stainless steel mesh. Stainless steel material has excellent corrosion resistance, can effectively resist the erosion of acidic substances and moisture in grease, prolong the service life of the equipment, and reduce the maintenance and replacement cost caused by corrosion. The surface of the stainless steel mesh is smooth, easy to clean, not easy to hide dirt, meets the hygiene and safety standards of the food processing industry, ensures that the filtered grease is not polluted, and guarantees the hygiene quality of the grease product.

[0052] According to some embodiments of the present application, the spiral purification assembly 310 is wound by multiple layers of spiral plates 311, and the two ends of the spiral plate 311 are fixedly connected with the outer wall of the center shaft 40 and the inner wall of the oil filter cylinder 30. The design of the spiral plate 311 increases the filtering area, so that the crude oil has a longer contact time with the filter screen when passing through the oil filter cylinder 30, improves the filtering efficiency, and more effectively removes impurities in the grease. The spiral structure helps to promote the flow of crude oil inside the oil filter cylinder 30, reduces the stagnation of oil flow, thereby improving the filtering speed and the efficiency of the entire filtering process.

[0053] According to some embodiments of the present application, the perforations of each layer of spiral plates 311 and the perforations of adjacent spiral plates 311 all or partially correspond to each other. The perforation corresponding design can make the oil flow be more finely divided and filtered when passing through each layer of spiral plates 311, improve the filtering precision, and ensure that finer impurities in the grease can also be effectively intercepted. The perforation corresponding design helps to produce an effect similar to "backwashing" when the crude oil passes through the filter screen, the flushing force generated when the oil flow passes through the corresponding holes helps to remove impurities on the filter screen, reduces filter screen blockage, and prolongs the cleaning cycle of the filter screen. The perforation corresponding design can optimize the flow dynamics of the oil flow inside the oil filter cylinder 30, so that the oil flow passes through the filter screen more uniformly, improves the filtering efficiency, and reduces local overload phenomenon.

[0054] According to some embodiments of the present application, the perforations of each spiral plate 311 are all or partially staggered with the perforations of the adjacent spiral plate 311. The staggered perforation design allows the oil flow to change direction multiple times when passing through the spiral plate 311, which helps to more effectively separate the solid impurities in the oil, improving the overall filtering effect. The staggered perforation design allows the oil flow to be more uniform inside the oil filter cartridge 30, avoiding the problem of excessive or insufficient flow in local areas, thereby improving the uniformity and efficiency of the filtration. The staggered perforation design helps to disperse the solid particles in the crude oil, reducing their concentrated accumulation on the filter screen, thereby reducing the risk of filter screen clogging.

[0055] The above detailed description of the present application is made in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the true spirit of the present application.
