Description

Technical Field

[0001] This utility model relates to the technical field of rapeseed oil filtration devices, and more specifically to a rapeseed oil pipeline pressure filtration device. Background Technology

[0002] Rapeseed oil is a vegetable oil extracted from rapeseed through pressing or leaching. In rapeseed oil processing, filtration is a crucial step in removing impurities (such as phospholipids, gums, mechanical residues, and moisture), directly affecting the oil's transparency, stability, and shelf life. Pipeline pressure filtration devices are highly efficient and continuous filtration equipment widely used in rapeseed oil refining processes, particularly suitable for removing fine suspended solids, colloidal impurities, and adsorbent residues after decolorization.

[0003] Chinese Patent No. CN214193162U discloses a rapeseed oil filtration device, including a rapeseed oil filtration structure. The rapeseed oil filtration structure includes a filter and a sealing cap. The rapeseed oil filtration structure also includes a sealing body. The sealing cap is connected to the upper end of the filter through the sealing body. The filter includes a housing and three buckles. The upper end of the buckle is engaged with the lower inner end of the sealing cap. The lower end of the buckle is rotatably mounted on the outer end of the housing. The upper end of the buckle is fixedly connected to the sealing body.

[0004] The existing device has the following problems when in use: the existing device requires opening the sealing cover first, placing the sealing cover in place, then taking out the filter screen inside the filter for slag removal, and after the filter screen is cleaned, putting the filter screen back in and closing the sealing cover. During this process, personnel need to repeatedly pick up and put down the heavy sealing cover, which is cumbersome, time-consuming and labor-intensive. In addition, rapeseed oil has high viscosity and poor fluidity, which can easily cause liquid residue to form on the inner wall of the cover during the filtration process. When the sealing cover is opened, the rapeseed oil residue on the sealing cover can easily drip onto the ground, polluting the working environment. Utility Model Content

[0023] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0024] Appendix Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0025] See attached document Figures 1-6 A rapeseed oil pipeline pressure filtration device includes a filter body 1 and a sealing cover 2 installed on the filter body 1. A connecting column 3 is fixedly connected to the bottom surface of the sealing cover 2, and a handle 4 is fixedly connected to the top of the connecting column 3. A limit component is provided around the connecting column 3, and the limit component is located below the handle 4. A rotating component is provided around the filter body 1, and the rotating component is connected to the limit component. An oil collecting component is provided around the filter body 1, and the oil collecting component includes a transmission mechanism and a collection mechanism. The transmission mechanism is connected to the rotating component.

[0026] Specifically, the limiting component includes a rectangular block 5, a first arc-shaped locking block 8, and a second arc-shaped locking block 10. The rectangular block 5 is located on the periphery of the connecting post 3 and is fixedly connected to the periphery of the connecting post 3. A connecting ring 6 is sleeved on the periphery of the connecting post 3. A rectangular groove 7 is opened on the inner wall of the connecting ring 6. The rectangular block 5 is slidably connected to the inner wall of the rectangular groove 7. The first arc-shaped locking block 8 and the second arc-shaped locking block 10 are located above the connecting ring 6 and are matched. The first arc-shaped locking block 8 and the second arc-shaped locking block 10 are rotatably connected to the same rotating shaft 9. The bottom end of the rotating shaft 9 is fixedly connected to the top surface of the handle 4.

[0027] In this embodiment, the top surfaces of the first arc-shaped locking block 8 and the second arc-shaped locking block 10 are both rough surfaces. When the handle 4 abuts against the top surfaces of the first arc-shaped locking block 8 and the second arc-shaped locking block 10, it will be tightly abutted against the first arc-shaped locking block 8 and the second arc-shaped locking block 10 due to gravity and friction, so that the first arc-shaped locking block 8 and the second arc-shaped locking block 10 will not loosen at this time.

[0028] Specifically, the rotating assembly includes a rotating rod 11 and a sleeve 12. The sleeve 12 is located on one side of the filter body 1. Two first fixing blocks 13 are fixedly connected to the side wall of the sleeve 12. The other end of the first fixing block 13 is fixedly connected to the periphery of the filter body 1. The rotating rod 11 is located inside the sleeve 12. A rotating ring 14 is fixedly connected to the periphery of the rotating rod 11. The rotating ring 14 is located inside the sleeve 12 and is rotatably connected to the inner wall of the sleeve 12. Two limiting grooves 15 are opened at the top of the sleeve 12. A limiting block 16 is fixedly connected to the periphery of the rotating rod 11. The limiting block 16 is located in the limiting groove 15 away from the first fixing block 13. A sliding groove 18 is opened on the periphery of the rotating rod 11. Two sliding blocks 17 are slidably connected in the sliding groove 18. The two sliding blocks 17 are fixedly connected to the same limiting block 16.

[0029] In this embodiment, the limiting block 16 and the limiting groove 15 can limit the movement between the rotating rod 11 and the sleeve 12, preventing the rotating rod 11 from rotating arbitrarily within the sleeve 12 and causing the sealing cover 2 to rotate, thus affecting the replacement of the filter screen by personnel.

[0030] Specifically, the transmission mechanism includes a first rotating column 19, a second rotating column 24, a first bevel gear 21, a second bevel gear 22, and a third bevel gear 23. The first rotating column 19 is fixedly connected to the bottom end of the rotating rod 11. A placement cylinder 20 is provided below the first rotating column 19. Two second fixing blocks 28 are fixedly connected to the periphery of the placement cylinder 20. The other end of the second fixing blocks 28 is fixedly connected to the periphery of the filter body 1. The first bevel gear 21 is located inside the placement cylinder 20 and is fixedly connected to the first rotating column 19 via a rotating shaft. The first bevel gear 21 is rotatably connected to the placement cylinder 20 via a rotating shaft. The second bevel gear 22 is located inside the placement cylinder 20 and is rotatably connected to the placement cylinder 20 via a rotating shaft. The third bevel gear 23 is located inside the placement cylinder 20 and is fixedly connected to the second rotating column 24 via a rotating shaft. The third bevel gear 23 is rotatably connected to the placement cylinder 20 via a rotating shaft. The second rotating column 24 is located below the placement cylinder 20. The first bevel gear 21 and the second bevel gear 22 are meshed together, and the second bevel gear 22 and the third bevel gear 23 are meshed together.

[0031] In this embodiment, by setting a first bevel gear 21, a second bevel gear 22, and a third bevel gear 23, when the rotating rod 11 rotates, it can drive the first bevel gear 21 to rotate through the first rotating column 19. The first rotating column 19 drives the first bevel gear 21 to rotate, the first bevel gear 21 drives the second bevel gear 22 to rotate, the second bevel gear 22 drives the third bevel gear 23 to rotate, the third bevel gear 23 drives the second rotating column 24 to rotate, and the second rotating column 24 drives the second oil collection box 26 to rotate. At this time, the second rotating column 24 and the first rotating column 19 rotate in opposite directions, so the first oil collection box 25 and the second oil collection box 26 will rotate in different directions.

[0032] Specifically, the collection mechanism includes a first oil collection box 25 and a second oil collection box 26. The first oil collection box 25 is fixedly connected to the periphery of the first rotating column 19, and the second oil collection box 26 is fixedly connected to the periphery of the second rotating column 24. The first oil collection box 25 and the second oil collection box 26 are located on both sides of the filter body 1, respectively.

[0033] Specifically, an inner cover 27 is fixedly installed inside the sealing cover 2, and the inner cover 27 is in the shape of an inverted funnel.

[0034] In this embodiment, the surface of the inner cover 27 is provided with several guide grooves, which can allow the residual rapeseed oil to flow towards the edge of the inner cover 27, so that the residual rapeseed oil can fall into the first oil collection box 25 and the second oil collection box 26 along the curvature of the inner cover 27.

[0035] It is worth mentioning that the structure and model of the filter body 1 and the sealing cover 2 are both relatively mature existing technologies, so they will not be described in detail here.

[0036] The working principle and usage process of this utility model are as follows: When personnel need to open the sealing cover 2 of this device to remove slag from the filter screen, they first disconnect the connection between the sealing cover 2 and the filter body 1, and then rotate the first arc-shaped locking block 8 and the second arc-shaped locking block 10 around the rotating shaft 9, so that there is sufficient gap between the first arc-shaped locking block 8 and the rotating shaft 9. At this time, the personnel pull the handle 4 upward, and the handle 4 drives the sealing cover 2 upward through the connecting column 3. The connecting column 3 drives the rectangular block 5 upward in the rectangular groove 7. When the sealing cover 2 moves to a sufficient height, the personnel reset the first arc-shaped locking block 8 and the second arc-shaped locking block 10. At this time, the first arc-shaped locking block 8 and the second arc-shaped locking block 10 are located below. The personnel release the handle 4, and the bottom surface of the rectangular block 5 abuts against the bottom surface of the first arc-shaped locking block 8 and the second arc-shaped locking block 10. At this time, the personnel lift the limiting block 16 upward and rotate the rotating rod 11. The rotating rod 11 drives the connecting column 3 to rotate around the axis of the rotating rod 11 through the connecting ring 6. The connecting column 3 drives the sealing cover 2 to rotate. When the rotating rod 11 rotates 180 degrees, the personnel release the sliding block 17, and the sliding block 17 is inserted into the limiting groove 15 near the first fixed block 13. At the same time, the rotating rod 11 drives the first rotating column 19 to rotate. The first rotating column 19 drives the first bevel gear 21 to rotate. The first bevel gear 21 drives the second bevel gear 22 to rotate. The second bevel gear 22 drives the third bevel gear 23 to rotate. The third bevel gear 23 drives the second rotating column 24 to rotate. The second rotating column 24 drives the second oil collection box 26 to rotate. At this time, the first oil collection box 25 and the second oil collection box 26 are located below the sealing cover 2. The rapeseed oil remaining on the inner cover 27 flows to the edge of the inner cover 27 and drips into the first oil collection box 25 and the second oil collection box 26 to avoid polluting the external environment.

[0037] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
