Description

Technical Field

[0001] This utility model relates to the field of rapeseed oil processing technology, specifically a high-speed refrigerated centrifuge for rapeseed oil processing. Background Technology

[0002] Commonly used oils in daily life include peanut oil, soybean oil, sesame oil, and rapeseed oil. Among them, rapeseed oil has a high extraction rate. Rapeseed oil is processed using hot pressing and cold pressing techniques, with cold pressing preserving the oil's properties more completely and resulting in a refreshing taste.

[0003] In the cold pressing of rapeseed oil, freezing and centrifugal separation are required. Freezing helps preserve the flavor of the rapeseed oil. Existing technologies involve first freezing ice packs and other frozen items in freezing equipment, followed by centrifugal separation. However, during freezing, the rapeseed oil tends to form an oil film, causing the oil to stick together during centrifugal separation, which is detrimental. The frozen ice packs also tend to accumulate in one area, hindering multi-site freezing of the oil. Nitrogen freezing is also used, but this is not only expensive, but the nitrogen introduced into the rapeseed oil can also affect its nutritional value. Therefore, existing technologies are not conducive to maintaining a frozen environment during centrifugal separation. To address these issues, we provide a high-speed refrigerated centrifuge for rapeseed oil processing. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] As shown in the attached figure Figure 1 and attached Figure 2 As shown, this utility model provides a technical solution: a high-speed refrigerated centrifuge for rapeseed oil processing, including a centrifuge housing, a feed funnel 1 connected to the top of the centrifuge housing, and a discharge valve body 2 installed at the bottom of the centrifuge housing. The centrifuge housing is divided into an upper housing 3 and a lower housing 4. A mounting base 30 is connected to the outside of the lower housing 4. The mounting base 30 has multiple mounting holes, and the mounting base 30 is fixed at the processing position by bolts and other fasteners.

[0027] The upper housing 3 and the lower housing 4 are designed to be detachable and assembled. A sealing rotating body 5 connects the upper housing 3 and the lower housing 4. The sealing rotating body 5 is assembled between the upper housing 3 and the lower housing 4. The specific installation sequence is shown in the appendix. Figure 2 As shown in the attached image, this is its state after installation. Figure 6 As shown, multiple centrifugal separation rods 6 are installed on the inner side of the sealed rotating body 5. The centrifugal separation rod 6 includes a connector 23 that is inserted into the inner wall of the mounting ring 18. One end of the connector 23 is forked with upper and lower ends. The centrifugal separation rod 6 is designed to be forked at both ends, which is beneficial for the initial centrifugal separation of the upper oil after it enters. Then, after the centrifugal separation, the lower part is subjected to a second centrifugal separation process.

[0028] A drive unit 7 is installed on the outside of the sealed rotating body 5. The upper housing 3 has two freezing chambers 8 inside, filled with frozen materials such as frozen bags or other freezing materials. The freezing chambers 8 are bonded to the inner wall of the upper housing 3 by adhesive or other means. A toggle rod 9 is provided inside the freezing chamber 8. A bidirectional threaded rod 10 is connected to the drive unit 7, and a pull member 11 is connected to the outside of the bidirectional threaded rod 10. A track groove 12 is provided on the outer wall of the freezing chamber 8, and the pull member 11 pulls the toggle rod 9 to slide along the track groove 12. The drive unit 7 drives the sealed rotating body 5 to rotate, causing the centrifugal separation rod 6 to centrifuge inside the centrifuge. Simultaneously, the drive unit 7, through the pull member 11, moves the toggle rod 9 along the inside of the freezing chamber 8, thereby reducing the concentration of frozen materials in one location and avoiding the impact on the nutritional value of the oil caused by nitrogen gas introduction as in the prior art.

[0029] For the power output section, please refer to the appendix. Figure 3 and attached Figure 4 As shown, the driving component 7 includes a drive motor 13 disposed outside the lower housing 4. The output end of the drive motor 13 is connected to a first helical gear 14. The top of the bidirectional threaded rod 10 is connected to a mounting plate 15 and is mounted to the outer wall of the upper housing 3. A connecting rod 16 is mounted at the bottom of the bidirectional threaded rod 10, and a second helical gear 17 meshing with the first helical gear 14 is connected to the bottom of the connecting rod 16. Under the output action of the drive motor 13, the first helical gear 14 drives the second helical gear 17 to rotate. Since the second helical gear 17 is fixed at the position of the connecting rod 16, the connecting rod 16 and the bidirectional threaded rod 10 begin to rotate along the position of the mounting plate 15. Since the drive gear 20 is fixedly connected to the outside of the connecting rod 16, it drives the gear ring 19 to rotate, thus driving multiple centrifugal separation rods 6 to rotate for centrifugal separation.

[0030] The sealing rotating body 5 includes a mounting ring 18 with an H-shaped cross-section. The upper end of the H-shaped mounting ring 18 is in contact with the upper housing 3, and the lower end of the H-shaped mounting ring 18 is in contact with the lower housing 4. A toothed ring 19 is connected to the outer wall of the mounting ring 18. A drive gear 20 that meshes with the toothed ring 19 is connected to the connecting rod 16. Two sealing ring strips 21 are installed inside the mounting ring 18. Sealing grooves 22 that engage with the sealing ring strips 21 are opened on the inner walls of both the upper housing 3 and the lower housing 4.

[0031] The pulling member 11 includes a threaded sleeve 24 fitted outside the bidirectional threaded rod 10. Spherical hinge seats 25 are connected to both sides of the threaded sleeve 24. A limiting plate 26 is connected to the outside of the actuating rod 9. The limiting plate 26 slides inside the track groove 12, and a spherical hinge seat 25 is also connected to the outside of the limiting plate 26. The two spherical hinge seats 25 are connected to a telescopic elastic rod 27. A return spring 28 is connected between the limiting plate 26 and the inner wall of the track groove 12. A guide rod 29 is connected to the mounting plate 15. A hole is opened on the threaded sleeve 24, and the guide rod 29 passes through the hole. When the bidirectional threaded rod 10 starts to rotate, the threaded sleeve 24, which is sleeved on the outside of the bidirectional threaded rod 10, starts to move up and down along the outside of the bidirectional threaded rod 10. Since the limiting plate 26 and the outside of the threaded sleeve 24 are hinged at the spherical hinge seat 25 by the telescopic elastic rod 27, when the threaded sleeve 24 moves upward, the telescopic elastic rod 27 starts to pull the two limiting plates 26 closer to the bidirectional threaded rod 10 at the same time. The return spring 28 is in a stretched state, and at the same time, the actuating rod 9 is moved inside the freezing chamber 8, reducing the freezing of the frozen material inside the freezing chamber 8. When the threaded sleeve 24 moves downward, the two limiting plates 26 move away from the bidirectional threaded rod 10, and the return spring 28 is in a compressed state, which causes the actuating rod 9 to move the frozen material on the other side of the freezing chamber 8.

[0032] Working principle: When using this device, the upper shell 3 and lower shell 4 are disassembled, the freezing chamber 8 shell is disassembled, frozen material is filled in, and then the freezing chamber 8 shell is re-bonded to the inner wall of the upper shell 3. Alternatively, the frozen material inside the freezing chamber 8 can be frozen using a direct freezing mechanism, thus enabling the reuse of the frozen material inside the freezing chamber 8. After the frozen material is prepared, the upper shell 3 and lower shell 4 are assembled. At this time, oil is poured in from the feed funnel 1. Under the output of the drive motor 13, the first helical gear 14 drives the second helical gear 17 to rotate. Since the second helical gear 17 is fixed at the position of the connecting rod 16, the connecting rod 16 and the bidirectional threaded rod 10 begin to rotate along the position of the mounting plate 15. Since the connecting rod 16 is externally connected to the drive gear 20, it drives the gear ring 19 to rotate, thus driving multiple centrifugal separation rods 6 to rotate for centrifugal separation. When the bidirectional threaded rod 10 starts to rotate, this... When the threaded sleeve 24, which is fitted outside the double-threaded rod 10, begins to move up and down along the outside of the double-threaded rod 10, the limiting plate 26 and the threaded sleeve 24 are hinged at the spherical hinge seat 25 by the telescopic elastic rod 27. When the threaded sleeve 24 moves upward, the telescopic elastic rod 27 simultaneously pulls the two limiting plates 26 closer to the double-threaded rod 10, and the return spring 28 is in a stretched state. At the same time, the actuating rod 9 is moved inside the freezing chamber 8, reducing the freezing of the frozen material inside the freezing chamber 8. When the threaded sleeve 24 moves downward, the two limiting plates 26 move away from the double-threaded rod 10, and the return spring 28 is in a compressed state. This causes the actuating rod 9 to move the frozen material on the other side of the freezing chamber 8. In this way, the freezing environment is maintained during centrifugal separation, avoiding the freezing of the frozen material in the existing situation, and also avoiding the loss of the nutritional value of the oil caused by nitrogen freezing. After centrifugal freezing treatment, it is discharged through the discharge valve body 2.
