Description

TECHNICAL FIELD

[0001] The utility model belongs to sesame oil processing technical field, concretely relates to a multistage filtering device of sesame oil. BACKGROUND

[0002] In the process of producing sesame oil, the sesame oil needs to be treated by multistage filtering to remove the oil residue in the oil.

[0003] The existing multistage filtering device of sesame oil can meet the basic demand of multistage filtering of sesame oil, but usually scrapes the filter structure by scraping structure. Although this method can scrape part of the oil residue remaining in the filter structure and avoid the filter hole of the filter structure being blocked by part of the oil residue, the bottom surface of the scraping structure is flush with the upper surface of the filter structure, that is, the scraping structure cannot be inserted into the filter hole of the filter structure, so part of the oil residue can be moved below the scraping structure but still be clamped in the filter hole of the filter, thereby continuing to block the filter hole of the scraping structure and being difficult to be effectively cleaned by the scraping structure. Therefore, the oil residue dredging effect is limited, which can affect the subsequent scraping effect and filtering efficiency.

[0004] For example, the patent document with the publication number CN214361216U discloses a cold-pressed sesame oil multistage oil filtering device. In the technical solution of the patent document, the telescopic air cylinder is connected with a rotating rod above, the rotating rod is sleeved with a fixed ring, the fixed ring is installed with scraping rods on both sides, the rotating rod penetrates the filter screen and is connected with the fixed ring, the fixed ring and the scraping rods are provided with three groups and are arranged on three groups of filter screens, and the bottom end surface of the scraping rod is attached to the upper end surface of the filter screen. The rotating rod is driven to rotate by the stirring motor, thereby driving the scraping rod to rotate and scraping the surface of the filter screen to extrude and clean the oil residue. However, since the bottom end surface of the scraping rod is attached to the upper end surface of the filter screen, that is, the hanging rod cannot be inserted into the mesh hole of the filter screen, so part of the oil residue can be extruded by the hanging rod into the filter hole of the filter screen but cannot pass through the filter hole of the filter screen and is firmly clamped in the mesh hole of the filter screen. Therefore, the oil residue cannot be effectively cleaned, which can affect the efficiency and effect of subsequent filtering of the oil. UTILITY MODEL CONTENTS
