Description

Technical Field

[0001] This utility model relates to the field of collagen extraction technology, and in particular to a centrifugal separation device for collagen extraction. Background Technology

[0002] In the collagen extraction process, centrifugation is a crucial step in separating proteins from impurities, and tubular centrifuges are widely used due to their high separation efficiency. Their core principle is to use the high-speed rotation of a drum to generate centrifugal force, causing components with different densities in the mixture to separate into strata, thereby separating the collagen essence.

[0003] However, existing tubular separators have significant technical limitations when processing collagen extracts. Firstly, impurities easily precipitate on the inner wall of the drum, and because the drum is a closed tubular structure, its inner wall lacks smoothness, allowing sticky impurities generated during collagen extraction to easily adhere and accumulate. Cleaning requires complete disassembly of the drum, which is cumbersome and time-consuming, severely reducing the efficiency of continuous equipment operation and increasing labor costs. Secondly, the drum's planar inner wall design, during high-speed rotation, causes the extract to flow along the inner wall under centrifugal force. The planar structure easily leads to turbulent flow interference, reducing stratification efficiency and affecting the purity of collagen separation. Thirdly, during high-speed rotation, mechanical friction generates heat, causing the drum temperature to rise. Collagen is temperature-sensitive; high temperatures easily denature its molecular structure, reducing the content of active ingredients, thus affecting the quality and application effect of the separated collagen. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a centrifugal separation device for collagen extraction. It solves the technical problems of turbulent liquid flow caused by the inner wall of the drum in traditional tubular separators, which affects the separation purity, and the easy adhesion of impurities to the inner wall, requiring disassembly and cleaning, thus affecting production efficiency. It also addresses the technical problems of rapid heating during high-speed drum rotation, which denatures collagen and affects quality. The device achieves spray cleaning of impurities on the inner wall of the drum without disassembly and cleaning, improving production efficiency, avoiding incomplete separation caused by local turbulence, and controlling the temperature of the drum.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a centrifugal separation device for collagen extraction, including a base, a separator fixedly connected to the base via a connecting rod, a rotating shaft rotatably connected to the central bearing at the top of the separator, a drum fixedly connected to the bottom of the rotating shaft, and the bottom of the drum rotatably connected to the central bearing at the bottom of the separator via the rotating shaft, turbulence protrusions arrayed and fixedly connected to the inner wall of the drum, a liquid collection assembly for collecting the extract is provided inside the separator, a lead screw rotatably connected to the guide groove at the top front of the base, a threaded slide plate threadedly connected to the lead screw and sliding on the inner wall of the guide groove, a liquid infusion probe fixedly connected to the front end of the threaded slide plate, a high-pressure nozzle for spraying high-pressure water to clean the inner wall of the drum fixedly connected to the bottom of the liquid infusion probe, and a lifting motor for driving the lead screw to rotate is installed at the top of the base.

[0006] A further improvement is that the rotating shaft is a hollow shaft that communicates with the drum. A sealing valve is installed on the top of the rotating shaft. The high-pressure nozzle is arranged coaxially with the rotating shaft, and the diameter of the high-pressure nozzle is smaller than the inner diameter of the through hole in the rotating shaft. The nozzle at the bottom of the high-pressure nozzle is tilted, with an tilt angle of 30°-45°.

[0007] A further improvement is that a guide rod is fixedly connected to the top of the separator, and the guide rod slides in the through hole on the threaded slide plate.

[0008] A further improvement is that the turbulence protrusions are arranged in a spiral array along the inner wall of the drum, and their outer ends are spherical arc surfaces with a height of 0.5-2mm.

[0009] A further improvement is that the liquid collection assembly includes an array of liquid outlets located on the top of the outer surface of the drum, a liquid collection plate fixed to the inner wall of the separator, a liquid outlet pipe for collecting the extract fixed to the separator, and a hollow structure at the bottom of the drum shaft, with a raw material pump inlet pipe rotatably connected inside its bottom bearing.

[0010] A further improvement is that the liquid collection plate is a hollow frustum structure, and there is a small gap between the liquid collection plate and the rotating drum.

[0011] A further improvement is that a booster pump is installed on the base, a three-way pipe is installed at the inlet of the booster pump, and one end of the three-way pipe extends into the bottom of the separator. A water supply pipe is installed at the outlet of the booster pump, with its end extending into the separator. Multiple nozzles facing the drum are arrayed on the water supply pipe, and multiple thermocouples for real-time temperature monitoring are vertically arrayed on the inner wall of the drum.

[0012] By means of the above technical solution, this utility model provides a centrifugal separation device for collagen extraction, which has at least the following beneficial effects: 1. This utility model uses a lifting motor to drive the lead screw to rotate, which in turn moves the threaded slide plate on the lead screw downward along the guide groove. This causes the high-pressure nozzle at the bottom of the infusion probe to penetrate into the drum through the central through hole of the rotating shaft. The nozzle at the bottom of the high-pressure nozzle is tilted at 30°, which better flushes and cleans the slowly rotating drum from top to bottom, thoroughly cleaning the impurities attached to its inner wall and turbulence protrusions. There is no need to disassemble the drum, making cleaning faster and more convenient, and improving production efficiency.

[0013] 2. This utility model arranges the turbulence protrusions along the inner wall of the drum in a spiral line consistent with the material flow direction. This can guide the material to form a spiral upward flow, extend the separation path, and avoid the liquid flow along the inner wall plane of the drum, which would form local eddies and cause incomplete separation. It can also push the settled impurities to the bottom of the drum to avoid secondary suspension of impurities.

[0014] 3. When the thermocouple detects that the temperature inside the drum is too high, the booster pump is started to pump the coolant into the water supply pipe through the three-way pipe and spray it onto the drum through the nozzle to cool it down quickly, so as to avoid the temperature from being too high and causing collagen denaturation, which would affect the quality. The coolant that slips off is extracted and sprayed out again through the port on the three-way pipe that extends into the separator, so as to avoid the coolant accumulating in the separator and affecting the rotation speed of the drum.

[0018] 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.

[0019] Example 1 The traditional tubular separator's inner drum wall causes turbulent flow, affecting separation purity. Furthermore, impurities easily adhere to the inner wall, requiring disassembly and cleaning, thus impacting production efficiency. Additionally, the drum heats up rapidly during high-speed rotation, causing collagen deformation and affecting quality. This embodiment provides a centrifugal separator for collagen extraction that can spray-clean impurities from the inner drum wall without disassembly, improving production efficiency and avoiding incomplete separation caused by localized turbulence. It also controls the drum temperature to prevent excessive heat from denaturing collagen and affecting quality. Please refer to... Figures 1-4 The centrifugal separation device for collagen extraction includes a base 1, a separator 2 fixedly connected to the base 1 via a connecting rod, a rotating shaft 3 rotatably connected to the top central bearing of the separator 2, a drum 4 fixedly connected to the bottom of the rotating shaft 3, and the bottom of the drum 4 rotatably connected to the bottom central bearing of the separator 2 via a rotating shaft. Turbulence protrusions 5 are arrayed and fixedly connected to the inner wall of the drum 4. A liquid collection assembly 6 for collecting the extract is provided inside the separator 2. A lead screw 7 is rotatably connected to the guide groove at the top front of the base 1. A threaded slide plate 8 is threadedly connected to the lead screw 7 and slides on the inner wall of the guide groove. A liquid infusion probe 9 is fixedly connected to the front end of the threaded slide plate 8. A high-pressure nozzle 10 for spraying high-pressure water to clean the inner wall of the drum 4 is fixedly connected to the bottom of the liquid infusion probe 9. A lifting motor 11 for driving the lead screw 7 to rotate is installed on the top of the base 1.

[0020] The rotating shaft 3 is a hollow shaft that communicates with the rotating drum 4. A sealing valve 31 is installed on the top of the rotating shaft 3. The high-pressure nozzle 10 is arranged coaxially with the rotating shaft 3, and the diameter of the high-pressure nozzle 10 is smaller than the inner diameter of the through hole in the rotating shaft 3. The nozzle at the bottom of the high-pressure nozzle 10 is tilted at an angle of 30°-45°. The motor is started by an external controller to drive the driving bevel gear to rotate, which in turn drives the driven bevel gear on the rotating shaft 3 to rotate, thereby driving the rotating shaft 3 and the rotating drum 4 on it to rotate in the separator 2 for centrifugal separation. When impurities adhere to the inner wall of the rotating drum 4, the feeding is stopped and the motor speed is reduced. Open the sealing valve 31 and connect the cleaning fluid tube to the top of the infusion probe 9. Then start the lifting motor 11 to drive the lead screw 7 to rotate, which in turn drives the threaded slide plate 8 on the lead screw 7 to move downward along the guide slide groove. This causes the high-pressure nozzle 10 at the bottom of the infusion probe 9 to penetrate into the drum 4 through the central through hole of the rotating shaft 3. The nozzle at the bottom of the high-pressure nozzle 10 is set at a 30° angle, which can better flush and clean the slowly rotating drum 4 from top to bottom, thoroughly cleaning the impurities attached to its inner wall and turbulence protrusions 5. There is no need to disassemble the drum 4, making cleaning faster and more convenient, and improving production efficiency.

[0021] Because the threaded slide plate 8 is relatively long, to prevent the front end from wobbling during its up-and-down sliding, which could cause the high-pressure nozzle 10 to collide with the inner wall of the drum 4 and cause damage, a guide rod 91 is fixedly connected to the top of the separator 2. The guide rod 91 is slidably installed in the through hole on the threaded slide plate 8. When the threaded slide plate 8 slides down, it slides on the guide rod 91 through the through hole, thereby providing a second support through the guide rod 91, preventing the front end of the guide rod 91 from wobbling and causing the high-pressure nozzle 10 to collide with the inner wall of the drum 4 and cause damage to both.

[0022] Specifically, the turbulence protrusions 5 are arranged in a spiral array along the inner wall of the drum 4, and their outer ends are spherical arc structures with a height of 0.5-2mm. The turbulence protrusions 5 are arranged in a spiral along the inner wall of the drum 4 in the same direction as the material flow, rather than being randomly distributed. This can guide the material to form a spiral upward flow, extend the separation path, and prevent the liquid flow from flowing along the inner wall plane of the drum 4, which would form local eddies and cause incomplete separation. It can also push the settled impurities to the bottom of the drum 4 to avoid secondary suspension of impurities.

[0023] Specifically, the liquid collection assembly 6 includes an array of liquid outlets 61 located on the top of the outer surface of the drum 4, a liquid collection plate 62 fixed to the inner wall of the separator 2, and a liquid outlet pipe 63 for collecting the extract fixed to the separator 2. The bottom shaft of the drum 4 is hollow, and a raw material pump inlet pipe 64 is rotatably connected inside its bottom bearing. The raw liquid is pumped into the bottom of the drum 4 through the inlet pipe 64. Then, under the centrifugal force generated by the high-speed rotating drum 4, the extract is transported to the liquid outlet 61 at the top of the drum 4 and thrown out, falling into the liquid collection plate 62 for collection, and then discharged through the liquid outlet pipe 63.

[0024] Specifically, the collection plate 62 has a hollow frustum structure, and there is a small gap between the collection plate 62 and the drum 4. The small gap prevents the drum 4 from continuously rubbing against the collection plate 62 when rotating at high speed, which would affect the service life of the drum 4 and cause local heating, thus affecting the collagen quality.

[0025] Example 2 Because the drum 4 heats up rapidly during high-speed rotation, causing collagen deformation and affecting quality, therefore, based on Example 1, as follows... Figures 1-4 As shown, a booster pump 121 is installed on the base 1. A three-way pipe 122 is installed at the inlet of the booster pump 121, and one end of the three-way pipe 122 extends into the bottom of the separator 2. A water supply pipe 123 is installed at the outlet of the booster pump 121, with its end extending into the separator 2. Multiple nozzles 124 facing the drum 4 are arrayed on the water supply pipe 123. Multiple thermocouples 125 for real-time temperature monitoring are vertically arrayed on the inner wall of the drum 4. When the thermocouples 125 detect that the temperature inside the drum 4 is too high, the booster pump 121 is started to pump coolant into the water supply pipe 123 through the three-way pipe 122 and spray it onto the drum 4 through the nozzles 124 to cool it down quickly and prevent the temperature from being too high, which could cause collagen denaturation and affect the quality. The coolant that slips off is extracted and sprayed out again through the port on the three-way pipe 122 that extends into the separator 2, preventing the coolant from accumulating inside the separator 2 and affecting the rotation speed of the drum 4.
