Description

Technical Field

[0001] This invention relates to the field of bone broth technology, and in particular to a centrifugal separation device for separating oil and water from bone meat residue in bone broth. Background Technology

[0002] Bones are highly nutritious, with 90% of their protein being collagen, chondroitin, and other bone-derived nutrients. Bone broth packets maximize the extraction of these nutrients, making them easily absorbed and utilized by the body. The production process for bone broth is as follows: First, the bones are crushed into small particles using a crusher. Then, the bone fragments are added to a... Figure 1 The filter cylinder shown has multiple filter holes (1) inside. A hook (2) is installed on the filter cylinder, and two steam holes (3) are symmetrically located at its bottom. The filter cylinder is lifted into a cooking kettle using a hoisting device for high-pressure cooking and extraction. After extraction, the filter cylinder is lifted out of the cooking kettle, and the bone residue is poured out and emptied. The bone broth in the cooking kettle is then allowed to stand and filter, undergoing oil-water separation, vacuum concentration, blending, sterilization, and bottling. Because bones have a porous structure, they can still absorb a large amount of oil and other nutrients after gravity separation during hoisting, resulting in waste.

[0003] Patent 202220031846.1 discloses a centrifugal separation device for chicken bone broth, including a separation tank. A separation cylinder and an oil cylinder are coaxially fixedly connected inside the separation tank. The oil cylinder is located inside the separation cylinder. The inner side of the separation cylinder, the outer side of the oil cylinder, and the bottom of the separation tank form a separation chamber. A stirring motor is installed at the top of the separation tank. The output end of the stirring motor is connected to a drive assembly, and the output end of the drive assembly is connected to a stirring frame. The stirring frame is located inside the separation chamber and is connected to a spiral blade with multiple filter holes. By driving the spiral blade with filter holes to rotate, the broth and oil are separated. Simultaneously, the device lifts bones and bone fragments, causing them to enter the discharge pipe, thus achieving a separation effect between the bones and bone fragments. This device separates bone and meat fragments from oil within the bone broth, resulting in the discharged bone and meat fragments still adsorbing a large amount of oil.

[0004] Patent 202421454836.4 discloses a solid-liquid centrifugal separation device for kitchen waste. By putting the waste into the filter cylinder and starting the motor below to drive the filter cylinder to rotate, solid-liquid centrifugal separation is achieved. However, this centrifugal device is not suitable for separating bone fragments. The reason is that in order to ensure the cooking effect, the diameter of the filter hole of the filter cylinder is 1cm, which is much larger than the size of bone and meat fragments. Directly using the filter cylinder for centrifugation will cause a large amount of bone and meat fragments to pass through the filter hole. Replacing it with a filter cylinder with smaller filter holes not only greatly increases the transfer time of bone and meat fragments, but also makes the small filter holes easy to be blocked by bone and meat fragments, and cleaning is also more cumbersome.

[0005] Adapting existing extraction and filtration cartridges for cooked bone and meat residues to achieve rapid and efficient separation of adsorbed oils is a challenge for enterprises to improve profitability. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] like Figure 1 As shown, the present invention is an adaptation modification of the filter cylinder 1 in the cooking pot. The filter cylinder 1 currently used has multiple filter holes evenly distributed on its circumference. Three hooks 2 are installed on the upper part of the filter cylinder 1. Two steam holes 3 are symmetrically opened at the bottom of the filter cylinder 1. The steam heating pipe in the cooking pot passes through the steam holes 3 to achieve internal heating. The bottom edge of the filter cylinder 1 protrudes downward to form three arc-shaped clamping plates 4.

[0022] like Figures 2 to 6As shown, a centrifugal separation device for oil and water in bone broth is disclosed. A filter cylinder 1 is suspended and placed inside the centrifugal separation device to achieve oil-residue separation. The centrifugal separation device includes an inner cylinder 6, an outer cylinder 5, a filter cloth 7, a thrust ball bearing 10, a retaining ring 8, an insert column 14, and a first rotating shaft 15. The inner cylinder 6 and outer cylinder 5 are coaxially arranged outside the filter cylinder 1. The inner cylinder 6 is a cylindrical structure with openings at both ends. Multiple filter holes are distributed on the circumference of the inner cylinder 6. The filter cloth 7 is installed on the inner surface of the inner cylinder 6. The diameter of the filter holes on the inner cylinder 6 is smaller than the diameter of the filter holes on the filter cylinder 1. The retaining ring 8 is located at the bottom of the inner cylinder 6 and is integrally sealed to the lower edge of the inner cylinder 6. The inner arc surface of the retaining ring 8 has a first retaining groove 9 that matches the retaining plate 4, meaning that the bottom edge of the filter cylinder 1 is directly placed on the retaining ring 8. 8. The filter cylinder 1 is supported and lifted upwards. The first groove 9 of the retaining ring 8 can securely fix the filter cylinder 1 through the retaining plate 4. The upper part of the thrust ball bearing 10 is coaxially fixedly connected to the retaining ring 8. Three support columns 11 are fixedly provided on the lower surface of the thrust ball bearing 10. The three support columns 11 are connected to the outer cylinder 5. The insertion column 14 and the first rotating shaft 15 are located below the filter cylinder 1. The insertion column 14 is U-shaped and the end of the insertion column 14 is spherical. The insertion column 14 matches the steam hole 3. The middle part of the insertion column 14 is fixedly connected to the first rotating shaft 15. Before the filter cylinder 1 is hoisted and placed downwards on the retaining ring 8, the insertion column 14 first positions the insertion into the steam hole 3. The rotation of the first rotating shaft 15 drives the insertion column 14, the filter cylinder 1, the retaining plate 8, and the inner cylinder 6 to form a centrifugal rotation relative to the outer cylinder 5.

[0023] like Figure 3 As shown, an annular slag collection bin 27 and liquid collection bin 12 are installed at the lower part of the outer cylinder 5. The slag collection bin 27 and liquid collection bin 12 are coaxially connected to the inner cylinder 5. The width of the liquid collection bin 12 extends at least from the outer cylinder 5 to the inner cylinder 6 to collect the grease flowing down from the outer cylinder 6. The width of the slag collection bin 27 extends from the liquid collection bin 12 beyond the inner ring of the clamping plate 8 to collect bone and meat scraps falling from the clamping plate 8. The bottoms of the slag collection bin 27 and the liquid collection bin 12 are inclined to facilitate material discharge. The bottom of the slag collection bin 27 is provided with a slag discharge port 28, and the bottom of the liquid collection bin 12 is provided with a liquid discharge port 13. A fixing plate 29 is horizontally installed inside the cylindrical structure formed in the middle of the slag collection bin 27. The first rotating shaft 15 passes through the fixing plate 29. A bearing can be further installed between the first rotating shaft 15 and the fixing plate 29 to reduce friction.

[0024] like Figure 10As shown, the filter cloth 7 is a cylindrical structure with openings at both the top and bottom. A cloth-stretching assembly is installed on the filter cloth 7. The cloth-stretching assembly includes an upper pressure ring 16 and a lower hanging ring 17. The upper edge of the filter cloth 7 is fixed to the inner ring of the upper pressure ring 16 by rivets. The upper pressure ring 16 is provided with a second groove 26 along its path. The upper edge of the inner cylinder 6 is stuck in the second groove 26. The lower edge of the filter cloth 7 is also fixed to the outer ring of the lower hanging ring 17 by rivets. Due to its gravity, the lower hanging ring 17 can effectively stretch the filter cloth 7 and make it stick tightly to the inner wall of the inner cylinder 6. The filter cloth 7 is used to intercept bone and meat residue thrown out by the filter holes on the filter cylinder 1. The grease flies to the inner wall of the outer cylinder 5 through the filter cloth 7 and the inner cylinder 6 in sequence.

[0025] like Figure 9 As shown, with repeated use, the accumulation of bone fragments on the retaining ring 8 will significantly affect the grease separation effect, requiring regular cleaning. The inner cylinder 6 is equipped with a pushing assembly, which includes four pushing plates 18, four pushing rods 21, four first baffles 22, four second baffles 24, four first springs 23, and four hydraulic cylinders 25. The four pushing plates 18 form a ring and are divided into upper and lower parts. The first baffles 22 are fixed to the bottom of the outer surface of the inner cylinder 6. One end of the pushing rod 21 is fixedly connected to the second baffle 24, and the other end of the pushing rod 21 passes through the first baffle 22 and the inner cylinder 6, and is fixedly connected to the lower half of the pushing plate 18. The pushing rod 21, the first baffle 22, and the inner cylinder 6 are slidably connected. The first spring 23 is fitted onto the pushing rod 21 and located between the first baffle 22 and the second baffle 24. Figure 4 As shown, a certain gap is left between the second baffle 24 and the outer cylinder 5 to avoid contact with the output end of the hydraulic cylinder 25 during rotation. Under normal conditions, the first spring 23 supports the second baffle 24 to make the pusher plate tightly attached to the inner wall of the inner cylinder 6. The hydraulic cylinder 25 is fixed outside the outer cylinder 5. The output end of the hydraulic cylinder 25 passes through the outer cylinder 5 and is slidably connected to the outer cylinder 5. The hydraulic cylinder 25 pushes the second baffle 24 to make the pusher plate 18 slide along the surface of the clamping plate 4 and toward the center of the clamping plate 4, thereby achieving the pushing effect of the pusher plate 18. The pusher plate 18 has a certain thickness. A right-angle opening 20 is provided between adjacent pusher plates 18. Two hydraulic cylinders 25 are started synchronously at intervals, and the remaining two hydraulic cylinders are started later. This can avoid the problem of mutual jamming caused by the synchronous displacement of the pusher plates 18.

[0026] like Figure 10 As shown, the lower lifting ring 17 has a triangular cross-section with the tip pointing towards the center. The outer ring surface of the upper half of the pusher plate 18 is provided with a pressing groove 19 that matches the lower lifting ring 17. The pressing groove 19 also has a triangular cross-section. Under the action of the first spring 23, the upper half of the pusher plate 18 is locked with the lower lifting ring 17, pressing the filter cloth 7 tightly against the inner wall of the inner cylinder 6, ensuring the stability of the filter cloth 7 during the centrifugation process. The filter cloth 7 inevitably shrinks or expands during use. The triangular lower lifting ring 17 and the triangular pressing groove 19 can offset the offset distance and continue to remain fixed.

[0027] A circular baffle plate 30 is placed on the outer cylinder 5. The ring width of the baffle plate 30 extends from the outer cylinder 5 to the hook 2, which does not affect the multiple hoisting of the filter cylinder 1. After centrifugation, the filter holes of the filter cylinder 1 will be blocked by bone and meat residue, which needs to be cleaned in time. A cleaning mechanism 31 is installed on the baffle plate 30 for cleaning.

[0028] like Figure 8 As shown, the unblocking mechanism 31 is installed in the gap between the filter cylinder 1 and the inner cylinder 6. The unblocking mechanism 31 includes a shell 32, a first push plate 35, a second push plate 36, an unblocking needle 37, a connecting rod 38, a second spring 39, an elliptical plate 40, and a second rotating shaft 41. The internal space of the shell 32 is divided into a square chamber 33 and a circular chamber 34, which are connected. The first push plate 35 and the second push plate 36 are vertically located in the square chamber 33, with the first push plate 35 located at the end away from the circular chamber 33. Two connecting rods 38 are fixedly connected to the first push plate 35 and the second push plate 36, respectively. The length of the first push plate 35 is less than the length of the second push plate 36. The first push plate 35 and the second push plate 36 are fixed symmetrically at the top and bottom. The unblocking needle 37 matches the filter holes on the filter cylinder 1. The diameter of the unblocking needle 37 is smaller than the diameter of the filter holes. The first push plate 35 passes through the outer shell 32 and is fixedly connected to it. The unclogging needle 37 is slidably sealed to the outer shell 32. The second spring 39 is located at the upper and lower ends of the square chamber 33. One end of the second spring 39 pushes the outer shell 32, and the other end of the second spring 39 pushes the second push plate 36. The second spring 39 rebounds and pushes the first push plate 35, the second push plate 36, the unclogging needle 37, and the connecting rod 38 to slide towards the circular chamber 34. The elliptical plate 40 is located in the circular chamber 34. The elliptical plate 40 is a plate structure with an elliptical cross-section. The second rotating shaft 41 is vertically fixed to the elliptical center of the second rotating shaft 41. The rotation of the second rotating shaft 41 drives the elliptical plate 40 to rotate and squeeze and push the first push plate 35, the second push plate 36, and the unclogging needle 37 to slide towards the filter cartridge 1 in the square chamber 33. The outer shell 32 is suspended below the baffle plate 30 through the connecting plate 42.

[0029] After each centrifugation, the position of the filter holes on filter cartridge 1 does not correspond to the position of the unclogging needle 37, thus failing to achieve the desired unclogging effect. Positioning and calibration are required. Figure 7As shown, a bevel gear 50 is installed at the lower part of the first rotating shaft 15. A first drive shaft 51 and a second drive shaft 48 are installed on the outer cylinder 5. The first drive shaft 51 and the second drive shaft 48 pass through the outer cylinder 5 and are rotatably connected. The end of the first drive shaft 51 is meshed with the bevel gear 50. A motor can be installed on the other end of the first drive shaft 51 for driving. The end of the second drive shaft 48 is provided with an incomplete gear 49 that matches the bevel gear 50. Rotating the incomplete gear 49 once can drive the bevel gear 50 to rotate a certain angle. Both the incomplete gear 49 and the bevel gear 50 are existing technologies. The intermittent motion realizes the continuous cleaning of the filter holes by the unclogging needle 37. A first gear 44 and a second gear 45 are installed on the baffle plate 30, and a first spline sleeve 43 is installed on the shaft of the first gear 44. A second spline sleeve 46 is installed on the shaft of the second gear 45. The baffle plate 30 is provided with round holes that match the first spline sleeve 43 and the second spline sleeve 46. The first spline sleeve 43 passes through the round hole and is splinedly connected to the end of the second rotating shaft 41. The second spline sleeve 46 passes through and is located in the round hole. A drive shaft 47 is installed in the middle of the second drive shaft 48. The drive shaft 47 passes through the liquid collection tank 12 and is rotatably and sealingly connected to the liquid collection tank 12. The bottom end of the drive shaft 47 is meshed with the second drive shaft 48 through a bevel gear. Figure 3 Two meshing bevel gears are shown in the diagram. The second spline sleeve 46 passes through the round hole and is connected to the top spline of the drive shaft 47. The spline connection is not a completely fixed connection. Personnel can pull out the first spline sleeve 43, the first gear 44, the second gear 45, and the second spline sleeve 46 from the round hole to cut off the linkage with the unblocking mechanism 31. At this time, under the action of the second spring 39, the unblocking needle retracts to avoid interfering with the rotation of the filter cylinder 1. At the same time, the baffle plate 30 can be hoisted and disassembled to clean the inside of the device.

[0030] To achieve the first precise positioning of the unblocking needle 37 and the filter holes of the filter cylinder 1, a first hexagonal tube 52 is fixedly installed on the first drive shaft 51, and a second hexagonal tube 53 is fixedly installed on the second drive shaft 48. The first hexagonal tube 52 and the second hexagonal tube 53 are respectively provided with a first scale 54, and the outer cylinder 5 is respectively provided with a second scale 55 that matches the first scale 54. When the operator uses a wrench to clamp the first hexagonal tube 52 and the second hexagonal tube 53 and rotates them to make the first scale 54 correspond to the second scale 55, the precise positioning can be achieved.

[0031] Working principle: Personnel hoist the filter cylinder 1 and place it on the retaining ring 8, so that the retaining plate 4 aligns with the first retaining groove 9 to achieve fixation. At this time, the insertion post 14 is located inside the steam hole 3. Two motors are installed outside the device. One motor drives the first drive shaft 51 to rotate, and the other drives the second drive shaft 48 to rotate. The first drive shaft 51 drives the first rotating shaft 15 and the insertion post 14 to rotate through the bevel gear 50. The insertion post 14 drives the filter cylinder 1, inner cylinder 6, filter cloth 7, retaining ring 8, cloth tensioning assembly, and pushing assembly to rotate. A small portion of bone and meat residue and grease falls onto the filter cloth 7 through the filter holes. After the filter cloth 7 intercepts the bone and meat residue, the remaining grease is thrown onto the inner wall of the outer cylinder 5 through the filter holes on the inner cylinder 6. The grease finally falls into the collection box. Collection is achieved in the liquid tank 12. Bone and meat residue falls onto the retaining ring 8 due to the obstruction of the filter cloth 7. After centrifugation, the filter cylinder 1 is lifted away. The first drive shaft 51 is rotated with a wrench to align the push rod 21 with the oil cylinder 25. The oil cylinder 25 is activated intermittently to push the push rod 21 and drive the pusher plate 18 forward, scraping the accumulated bone and meat residue and letting it fall into the slag collection bin 27 below. The oil cylinder 25 is retracted, and the pusher plate 18 is reset under the action of the first spring 23. The other oil cylinder 25 is activated at intervals to scrape away the bone and meat residue in front of the pusher plate 18. The filter cloth 7 needs to be disassembled and cleaned after a period of use. The oil cylinder 25 is activated intermittently to prevent the pusher plate 18 from pressing on the lower lifting ring 17. Personnel then press the upper pressure ring. 16. Remove the filter cloth 7 from the inner cylinder 6, clean it, and reinstall it. After emptying the bone and meat residue inside, place the filter cylinder 1 back onto the retaining ring 8. Insert the first spline sleeve 43, the first gear 44, the second gear 45, and the second spline sleeve 46 into the round hole of the baffle plate 30 so that the first spline sleeve 43 is inserted into the second rotating shaft 41 and the second spline sleeve 46 is inserted into the drive shaft 47. Use a wrench to rotate the first hexagonal tube 52 and the second hexagonal tube 53 to reposition them so that the unblocking needle 37 is aligned with the filter hole. The motor drives the second drive shaft 48 to rotate. The second drive shaft 48 drives the second drive shaft 48 in sequence through the drive shaft 47, the second gear 45, the first gear 44, and the second rotating shaft 41. The elliptical plate 40 rotates, pushing the second push plate 36 and the first push plate 35 forward, and simultaneously compressing the second spring 39. The unclogging needle 37 is pushed into the filter holes to achieve a single-row cleaning effect. At the same time, the second drive shaft 48 drives the first rotating shaft 15 and the filter cylinder 1 to rotate at a certain angle through the incomplete gear 49, continuously cleaning the filter holes of the second vertical row until all are cleaned. After that, the personnel remove the first gear 44 and the first spline sleeve 43, and the compressed second spring 39 resets to retract the unclogging needle 37.
