Description

Technical Field

[0001] The present invention relates to the technical field of earthworm processing, and particularly relates to an extraction and separation device and an extraction and separation method for earthworm peptides. Background Art

[0002] Earthworm protein is extracted from earthworms. Earthworms, also known as earthworms, are one of the important traditional Chinese medicines in China. In addition to having high nutritional value, earthworms also have many health care functions, which can enhance the disease resistance of the human body and improve people's health level. They are involved in various human systems such as the cardiovascular system, the blood system, the immune system, etc. The production process of earthworm protein requires steps such as raw material treatment, enzymatic hydrolysis extraction, separation and purification, and drying and shaping.

[0003] In the solid-liquid separation step, the enzymatic hydrolysate obtained in the enzymatic hydrolysis extraction step needs to be input into a horizontal centrifuge for centrifugal filtration to obtain an extract, and then the extract is concentrated and dried to complete the final process. At present, the solid-liquid separation of earthworm protease hydrolysate mostly uses a horizontal centrifuge. However, the enzymatic hydrolysate of earthworm protein is a material with high concentration and viscosity, and the processing capacity of the horizontal centrifuge will be significantly reduced, and it is prone to blockage. Therefore, an extraction and separation device and an extraction and separation method for earthworm peptides are proposed. Summary of the Invention

[0014] S1. Conveying materials: quantitatively conveying earthworm protease hydrolysate into the inside of the centrifugal filter cylinder through a feed pipe, a bent pipe and a self-rotating pipe;

[0015] S2. Solid-liquid separation: Two centrifugal motors respectively drive the centrifugal filter cylinder to revolve and rotate, perform double centrifugal separation on the enzyme hydrolysate, cause liquid substances to precipitate and splash inside the separation tank, and finally discharge them through a drain pipe. The remaining solid materials remain inside the centrifugal filter cylinder;

[0016] S3. Pushing of solid materials: The feeding electric push rod drives the feeding push plate to move upward, and pushes the solid materials accumulated at the bottom of the centrifugal filter cylinder and attached to the inner wall of the centrifugal filter cylinder to the position where the top discharge pipe is located;

[0017] S4. Docking of pipelines: The two positioning motors respectively drive the telescopic shafts to rotate to the positions aligned with the positioning sockets. Then, the positioning electric push rods drive the telescopic ends of the telescopic shafts to be inserted into the positioning sockets. At this time, the two positioning motors respectively drive the centrifugal filter drums to continue rotating until the discharge pipes rotate to the positions corresponding to the discharge telescopic pipes. The discharge electric push rods will drive the telescopic ends of the discharge telescopic pipes to move obliquely downward, and then be inserted into the discharge pipes at the tops of the centrifugal filter drums, so that the centrifugal filter drums are connected to the suction pipes through the discharge pipes and the discharge telescopic pipes;

[0018] S5. Discharge of solid materials: The externally connected suction device can suck out the solid materials accumulated on the top of the centrifugal filter drum.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention can drive the centrifugal filter drum to perform both revolution and rotation simultaneously. By means of two centrifugal motors respectively driving the centrifugal filter drum to perform double circular motions, double centrifugation is achieved, thereby improving the centrifugal separation effect. At the same time, the solid materials are automatically discharged by means of the discharge assembly, reducing the processing time, improving the processing capacity of the separation equipment, and at the same time reducing the risk of blockage of the filter holes on the centrifugal filter drum;

[0021] 2. By setting the discharge assembly in the present invention, after solid-liquid separation, the feeding electric push rod will drive the feeding push plate to push the solid materials accumulated at the bottom of the centrifugal filter drum to the position where the top discharge pipe is located and be sucked to the outside. At the same time, the feeding push plate scrapes the inner wall of the centrifugal filter drum to prevent the filter holes on the inner wall of the centrifugal filter drum from being blocked, and compresses the solid materials to further precipitate the liquid substances, realizing the automatic discharge of the solid materials;

[0022] 3. By setting the steering unit in the present invention, after centrifugation is completed, the positioning motor will respectively drive the telescopic shaft to rotate to the position aligned with the positioning socket by means of the laser locator and the laser receiver. Then, the positioning electric push rod drives the telescopic end of the telescopic shaft to be inserted into the positioning socket. At this time, the two positioning motors drive the centrifugal filter drum to continue rotating until the discharge pipe rotates to the position corresponding to the discharge telescopic pipe, realizing the automatic positioning of the discharge telescopic pipe and the discharge pipe, which is convenient for their docking;

[0023] 4. By setting the suction docking unit in the present invention, after the solid materials are sent to the top of the centrifugal filter drum, the discharge electric push rod will drive the telescopic end of the discharge telescopic pipe to be inserted into the discharge pipe, so that the centrifugal filter drum is connected to the suction pipe through the discharge pipe and the discharge telescopic pipe.

[0038] As Figures 1 to 8 shown, an extraction and separation device for earthworm peptides includes a separation tank 1. As Figure 2 shown, a rotating disk 2 is rotatably installed inside the separation tank 1. A suspension bracket 3 is fixedly installed on the top of the rotating disk 2. As Figure 3 shown, a bent pipe 4 is fixedly installed at the top of the suspension bracket 3. The top end of the bent pipe 4 is vertically upward and rotatably installed with a feed pipe 5. As Figure 4 shown, the bottom end of the bent pipe 4 is obliquely downward and rotatably installed with a self-rotating pipe 6. The bottom end of the self-rotating pipe 6 is fixedly installed with a centrifugal filter cylinder 7. A discharge pipe 13 is fixedly installed on the top side wall of the centrifugal filter cylinder 7. A discharge control valve 14 is provided on the discharge pipe 13. As Figure 2 shown, a transmission chamber 101 is provided at the bottom of the separation tank 1. A first transmission box 9 is fixedly installed inside the transmission chamber 101. As Figure 3 shown, a self-rotating frame 8 is fixedly installed on the centrifugal filter cylinder 7. A second transmission box 10 is provided at the bottom end of the self-rotating frame 8. As Figure 6As shown, centrifugal motors 11 are fixedly installed inside the first transmission case 9 and the second transmission case 10 respectively. The output ends of the centrifugal motors 11 are all drivingly installed with centrifugal shafts 12. In this embodiment, the centrifugal motors 11 are not provided with self-locking structures. The tops of the two centrifugal shafts 12 respectively penetrate through the first transmission case 9 and the second transmission case 10 and are fixedly connected to the rotating disk 2 and the self-rotating frame 8 respectively. In this embodiment, a control valve for controlling liquid discharge is provided on the liquid discharge pipe 36, such as Figure 2 As shown, a liquid discharge pipe 36 is fixedly installed on one side of the bottom of the separation tank 1. A discharge assembly for discharging the separated solid materials is provided on the centrifugal filter cartridge 7; specifically, when the extraction and separation equipment for earthworm peptides is in use, a certain amount of earthworm protease hydrolysis solution is first transported into the centrifugal filter cartridge 7 through the feed pipe 5, the bent pipe 4 and the self-rotating pipe 6. Then, the centrifugal motor 11 in the first transmission case 9 starts to operate, and drives the centrifugal filter cartridge 7 to start rotating around the feed pipe 5 through the centrifugal shaft 12 and the suspension bracket 3. At the same time, the centrifugal motor 11 in the second transmission case 10 starts to drive the self-rotating frame 8 to drive the centrifugal filter cartridge 7 to rotate around the self-rotating pipe 6, so as to perform centrifugal separation on the hydrolysis solution inside the centrifugal filter cartridge 7, so that the liquid substance precipitates from the centrifugal filter cartridge 7 and splashes inside the separation tank 1, and finally is led out through the liquid discharge pipe 36. The remaining solid materials remain inside the centrifugal filter cartridge 7. At this time, the two centrifugal motors 11 stop rotating, so that the centrifugal filter cartridge 7 stops. Then, the solid materials in the centrifugal filter cartridge 7 are discharged through the discharge assembly, and the hydrolysis solution is re-transported into the centrifugal filter cartridge 7 for secondary centrifugation, realizing the solid-liquid centrifugal separation of the hydrolysis solution. By means of the two centrifugal motors 11 respectively driving the centrifugal filter cartridge 7 to perform double circular motions, double centrifugation is realized, thereby improving the centrifugal separation effect. At the same time, by means of the discharge assembly, the solid materials are automatically discharged, reducing the processing time, improving the processing capacity of the separation equipment, and at the same time reducing the risk of blockage of the filter holes on the centrifugal filter cartridge 7.

[0039] Such as Figure 4 As shown, the discharge assembly includes a feeding electric push rod 15 arranged at the bottom end of the centrifugal filter cartridge 7. The feeding electric push rod 15 is fixedly installed at the bottom of the self-rotating frame 8, such as Figure 5 As shown, the telescopic end of the feeding electric push rod 15 extends into the centrifugal filter cartridge 7 and is fixedly installed with a feeding push plate 16. In this embodiment, the feeding push plate 16 is adapted to the centrifugal filter cartridge 7, such as Figure 2As shown in the figure, a suction pipe 17 is fixedly installed at the top of the separation tank 1. One end of the suction pipe 17 extends into the separation tank 1 and corresponds to the position of the discharge pipe 13. In this embodiment, a suction device is provided at one end of the suction pipe 17, and a suction docking unit for controlling the connection state between the discharge pipe 13 and the suction pipe 17 is arranged inside the separation tank 1. Specifically, by setting the discharge assembly, after solid-liquid separation, the feeding electric push rod 15 at the bottom of the centrifugal filter cylinder 7 will drive its telescopic end to drive the feeding push plate 16 to move upward inside the centrifugal filter cylinder 7, so that the solid materials accumulated at the bottom of the centrifugal filter cylinder 7 are sent to the position where the top discharge pipe 13 is located and sucked to the outside. At the same time, the feeding push plate 16 scrapes the inner wall of the centrifugal filter cylinder 7, so that the materials remaining on the inner wall of the centrifugal filter cylinder 7 are sent to the top, preventing the filter holes on the inner wall of the centrifugal filter cylinder 7 from being blocked, and compressing the solid materials to further precipitate the liquid substances, realizing the automatic discharge of the solid materials.

[0040] As Figure 8 shown in the figure, the suction docking unit includes a discharge telescopic pipe 18 fixedly installed at one end of the suction pipe 17 located inside the separation tank 1. A discharge electric push rod 19 parallel to the discharge telescopic pipe 18 is fixedly installed on the inner wall of the top of the separation tank 1. The telescopic end of the discharge electric push rod 19 is fixedly connected to the telescopic end of the discharge telescopic pipe 18. Steering units for steering and positioning are arranged inside both the first transmission box 9 and the second transmission box 10 when the discharge telescopic pipe 18 is docked with the discharge pipe 13. Specifically, by setting the suction docking unit, after the solid materials are sent to the top of the centrifugal filter cylinder 7, the discharge electric push rod 19 will drive the telescopic end of the discharge telescopic pipe 18 to move obliquely downward, and then be inserted into the discharge pipe 13 at the top of the centrifugal filter cylinder 7, so that the centrifugal filter cylinder 7 is communicated with the suction pipe 17 through the discharge pipe 13 and the discharge telescopic pipe 18. Thus, the external suction device can suck out the solid materials accumulated at the top of the centrifugal filter cylinder 7. After the suction is completed, the discharge electric push rod 19 drives the discharge telescopic pipe 18 to reset, preventing the connection relationship between the discharge telescopic pipe 18 and the discharge pipe 13 from hindering the double rotation of the centrifugal filter cylinder 7.

[0041] As Figure 8 shown in the figure, a sealing ring 20 is fixedly sleeved on the telescopic end of the discharge telescopic pipe 18, and a sealing disc 21 adapted to the sealing ring 20 is fixedly installed at one end of the discharge pipe 13. Specifically, by setting the sealing ring 20 and the sealing disc 21, when the discharge telescopic pipe 18 is docked with the discharge pipe 13, the sealing ring 20 on the discharge telescopic pipe 18 will be synchronously inserted into the sealing disc 21, thereby sealing the docking part of the discharge telescopic pipe 18 and the discharge pipe 13 and preventing the leakage of solid materials.

[0042] As Figure 6As shown, the steering unit includes two positioning motors 25 fixedly installed inside the first transmission case 9 and the second transmission case 10 respectively. In this embodiment, the positioning motor 25 is a stepper motor, and the output ends of the positioning motors 25 are both drivingly installed with telescopic shafts 26. As Figure 3 shown, gear boxes 22 are fixedly installed on the tops of both the first transmission case 9 and the second transmission case 10. The gear box 22 located on the top of the second transmission case 10 is rotatably connected to the rotation frame 8. As Figure 6 shown, inside each of the gear boxes 22, there are meshing centrifugal gears 23 and positioning gears 24. The centrifugal shafts 12 all penetrate through the gear boxes 22 and are rotatably connected to the gear boxes 22. The centrifugal gears 23 are fixedly sleeved on the centrifugal shafts 12. As Figure 7 shown, positioning shafts 27 are rotatably installed inside the gear boxes 22. The positioning gears 24 are fixedly sleeved on the positioning shafts 27. The bottom ends of the two positioning shafts 27 respectively penetrate through the first transmission case 9 and the second transmission case 10 and are respectively rotatably connected to the first transmission case 9 and the second transmission case 10. At the bottom ends of the positioning shafts 27, positioning socket cylinders 28 adapted to the telescopic shafts 26 are fixedly installed. In this embodiment, key grooves adapted to the telescopic ends of the telescopic shafts 26 are provided inside the positioning socket cylinders 28. Positioning electric push rods 29 parallel to the telescopic shafts 26 are fixedly installed inside both the first transmission case 9 and the second transmission case 10. The telescopic ends of the positioning electric push rods 29 are both fixedly installed with linkage frames 30. One ends of the linkage frames 30 are respectively rotatably connected to the telescopic ends of the telescopic shafts 26. In this embodiment, the linkage frames 30 are made of a transparent material to avoid obstructing the laser positioning of the laser locator 31 and the laser receiver 32. Specifically, by setting the steering unit, after centrifugation, the positioning motors 25 in the first transmission case 9 and the second transmission case 10 will respectively drive the telescopic shafts 26 to rotate to positions aligned with the positioning socket cylinders 28, and then the positioning electric push rods 29 drive the telescopic ends of the telescopic shafts 26 to be inserted into the positioning socket cylinders 28 through the linkage frames 30. At this time, the two positioning motors 25 respectively drive the two positioning shafts 27 to rotate, and then drive the centrifugal shafts 12 to rotate through the positioning gears 24 and the centrifugal gears 23, so that the centrifugal filter cartridge 7 continues to rotate until the discharge pipe 13 rotates to a position corresponding to the discharge telescopic pipe 18, realizing the automatic positioning of the discharge telescopic pipe 18 and the discharge pipe 13 and facilitating their docking.

[0043] As Figure 7As shown, a laser locator 31 is fixedly installed on the side wall of the positioning insertion cylinder 28, a laser receiver 32 adapted to the laser locator 31 is fixedly installed on the side wall of the telescopic shaft 26, and evenly distributed balance weights 33 are fixedly installed on the side wall of the positioning insertion cylinder 28; specifically, by setting the laser locator 31 and the laser receiver 32, during centrifugation, the centrifugal shaft 12 will drive the positioning shaft 27 to rotate synchronously. After the centrifugal motor 11 stops rotating, the positioning motor 25 will drive the telescopic shaft 26 to rotate slowly. At the same time, the laser locator 31 emits positioning laser towards the position of the positioning motor 25 until the laser receiver 32 receives the laser signal emitted by the laser locator 31. At this time, the positioning motor 25 stops rotating, and the telescopic shaft 26 and the positioning insertion cylinder 28 are aligned and then docked, thereby realizing the automatic positioning of the telescopic shaft 26 and the positioning insertion cylinder 28. At the same time, according to the total rotation angle of the two telescopic shafts 26 during positioning, the angles between the current discharge pipe 13 and the discharge telescopic pipe 18 can be measured respectively, so as to facilitate the positioning and docking of the discharge pipe 13 and the discharge telescopic pipe 18. The balance weights 33 can keep the positioning shaft 27 in a balanced state when the positioning shaft 27 and the centrifugal shaft 12 perform centrifugal rotation.

[0044] As Figure 2 shown, an annular ball slide rail 34 is fixedly installed on the inner wall of the separation tank 1, a sliding sleeve 35 is fixedly installed at the bottom of the second transmission box 10, and the sliding sleeve 35 is slidably installed on the annular ball slide rail 34; specifically, by setting the annular ball slide rail 34 and the sliding sleeve 35, during the centrifugation of the centrifugal filter cartridge 7, the self-rotating frame 8 will drive the sliding sleeve 35 to rotate synchronously on the annular ball slide rail 34. Thus, with the mutual cooperation of the annular ball slide rail 34 and the sliding sleeve 35, the second transmission box 10 is supported, making the centrifugal movement of the centrifugal filter cartridge 7 more stable.

[0045] As Figure 9 shown, a method for extracting and separating earthworm peptides includes the following steps:

[0046] S1. Conveying materials: A certain amount of earthworm protease hydrolysis solution is conveyed into the centrifugal filter cartridge 7 through the feed pipe 5, the bent pipe 4 and the self-rotating pipe 6.

[0047] S2. Solid-liquid separation: Two centrifugal motors 11 drive the centrifugal filter cartridge 7 to revolve and rotate respectively, performing double centrifugal separation on the hydrolysis solution, so that the liquid substances are precipitated and sputtered inside the separation tank 1, and finally are discharged through the drain pipe 36, and the remaining solid materials remain inside the centrifugal filter cartridge 7.

[0048] S3. Pushing the solid materials: The feeding electric push rod 15 drives the feeding push plate 16 to move upward, pushing the solid materials accumulated at the bottom of the centrifugal filter cartridge 7 and attached to the inner wall of the centrifugal filter cartridge 7 to the position where the top discharge pipe 13 is located.

[0049] S4. Docking of pipelines: The two positioning motors 25 respectively drive the telescopic shafts 26 to rotate to the positions aligned with the positioning socket cylinders 28, and then the positioning electric push rods 29 drive the telescopic ends of the telescopic shafts 26 to be inserted into the positioning socket cylinders 28. At this time, the two positioning motors 25 respectively drive the centrifugal filter cylinders 7 to continue rotating until the discharge pipe 13 rotates to the position corresponding to the discharge telescopic pipe 18. The discharge electric push rod 19 will drive the telescopic end of the discharge telescopic pipe 18 to move obliquely downward, and then be inserted into the discharge pipe 13 at the top of the centrifugal filter cylinder 7, so that the centrifugal filter cylinder 7 is communicated with the suction pipe 17 through the discharge pipe 13 and the discharge telescopic pipe 18;

[0050] S5. Discharge of solid materials: The externally connected suction device can suck out the solid materials accumulated at the top of the centrifugal filter cylinder 7. After the suction is completed, the enzymatic hydrolysate is re-transported into the centrifugal filter cylinder 7 for secondary centrifugation.

[0051] In summary: When the extraction and separation equipment for earthworm peptides is in use, first, a certain amount of earthworm protease hydrolysis solution is transported into the interior of the centrifugal filter cylinder 7 through the feed pipe 5 via the bent pipe 4 and the rotating pipe 6. Then, the centrifugal motor 11 in the first transmission box 9 starts to operate, driving the centrifugal filter cylinder 7 to rotate around the feed pipe 5 through the centrifugal shaft 12 and the suspension bracket 3. At the same time, the centrifugal motor 11 in the second transmission box 10 starts to drive the rotating frame 8 to drive the centrifugal filter cylinder 7 to rotate around the rotating pipe 6, thereby centrifugally separating the hydrolysis solution inside the centrifugal filter cylinder 7, causing the liquid substance to precipitate from the centrifugal filter cylinder 7 and splash inside the separation tank 1, and finally being discharged through the drain pipe 36. The remaining solid materials remain inside the centrifugal filter cylinder 7. At this time, the two centrifugal motors 11 stop rotating, causing the centrifugal filter cylinder 7 to stop. Then, the solid materials in the centrifugal filter cylinder 7 are discharged through the discharge assembly, and the hydrolysis solution is re-transported into the centrifugal filter cylinder 7 for a second round of centrifugation to achieve solid-liquid centrifugal separation of the hydrolysis solution. By means of the two centrifugal motors 11 respectively driving the centrifugal filter cylinder 7 to perform double circular motions, double centrifugation is achieved, thereby improving the centrifugal separation effect. At the same time, by means of the discharge assembly, the solid materials are automatically discharged, reducing the processing time, improving the processing capacity of the separation equipment, and at the same time reducing the risk of blockage of the filter holes on the centrifugal filter cylinder 7. By setting the discharge assembly, after solid-liquid separation, the feeding electric push rod 15 at the bottom of the centrifugal filter cylinder 7 will drive its telescopic end to drive the feeding push plate 16 to move upward inside the centrifugal filter cylinder 7, sending the solid materials accumulated at the bottom of the centrifugal filter cylinder 7 to the position where the top discharge pipe 13 is located and being suctioned to the outside. At the same time, the feeding push plate 16 scrapes the inner wall of the centrifugal filter cylinder 7, sending the materials remaining on the inner wall of the centrifugal filter cylinder 7 to the top, preventing the filter holes on the inner wall of the centrifugal filter cylinder 7 from being blocked, and compressing the solid materials to further precipitate the liquid substance, realizing the automatic discharge of the solid materials. By setting the suction docking unit, after the solid materials are sent to the top of the centrifugal filter cylinder 7, the discharge electric push rod 19 will drive the telescopic end of the discharge telescopic pipe 18 to move obliquely downward, and then be inserted into the discharge pipe 13 at the top of the centrifugal filter cylinder 7, so that the centrifugal filter cylinder 7 is connected to the suction pipe 17 through the discharge pipe 13 and the discharge telescopic pipe 18. Then, the external suction equipment can suck out the solid materials accumulated at the top of the centrifugal filter cylinder 7. After the suction is completed, the discharge electric push rod 19 drives the discharge telescopic pipe 18 to reset, preventing the connection relationship between the discharge telescopic pipe 18 and the discharge pipe 13 from hindering the double rotation of the centrifugal filter cylinder 7. By setting the sealing ring 20 and the sealing disk 21, when the discharge telescopic pipe 18 is docked with the discharge pipe 13, the sealing ring 20 on the discharge telescopic pipe 18 will be synchronously inserted into the sealing disk 21, thereby sealing the docking part of the discharge telescopic pipe 18 and the discharge pipe 13 to prevent the leakage of solid materials. By setting the steering unit, after centrifugation, the positioning motors 25 in the first transmission box 9 and the second transmission box 10 will respectively drive the telescopic shafts 26 to rotate to the position aligned with the positioning sockets 28.Then the positioning electric push rod 29 drives the telescopic end of the telescopic shaft 26 to be inserted into the positioning socket cylinder 28 through the linkage frame 30. At this time, the two positioning motors 25 respectively drive the two positioning shafts 27 to rotate, and then drive the centrifugal shaft 12 to rotate through the positioning gears 24 and the centrifugal gears 23, so that the centrifugal filter cylinder 7 continues to rotate until the discharge pipe 13 rotates to a position corresponding to the discharge telescopic pipe 18, realizing the automatic positioning of the discharge telescopic pipe 18 and the discharge pipe 13, which is convenient for their docking. By setting the laser locator 31 and the laser receiver 32, during centrifugation, the centrifugal shaft 12 will drive the positioning shaft 27 to rotate synchronously. After the centrifugal motor 11 stops rotating, the positioning motor 25 will drive the telescopic shaft 26 to rotate slowly. At the same time, the laser locator 31 emits positioning laser towards the position of the positioning motor 25 until the laser receiver 32 receives the laser signal emitted by the laser locator 31. At this time, the positioning motor 25 stops rotating, and the telescopic shaft 26 and the positioning socket cylinder 28 remain in alignment and then dock, thus realizing the automatic positioning of the telescopic shaft 26 and the positioning socket cylinder 28. At the same time, according to the total rotation angle of the two telescopic shafts 26 during positioning, the angles between the current discharge pipe 13 and the discharge telescopic pipe 18 can be measured respectively, so as to facilitate the positioning and docking of the discharge pipe 13 and the discharge telescopic pipe 18. The balance weight 33 can keep the positioning shaft 27 in a balanced state when the positioning shaft 27 and the centrifugal shaft 12 perform centrifugal rotation. By setting the annular ball slide rail 34 and the sliding sleeve 35, during the centrifugation process of the centrifugal filter cylinder 7, the self-rotating frame 8 will drive the sliding sleeve 35 to rotate synchronously on the annular ball slide rail 34, so as to support the second transmission box 10 with the mutual cooperation of the annular ball slide rail 34 and the sliding sleeve 35, making the centrifugal motion of the centrifugal filter cylinder 7 more stable.
