[0030] In this embodiment: the protection mechanism 1 includes a protection cover 11, a protection seat 12, a first outlet pipe 13, a second outlet pipe 14, a rotating drum 15, a trigger assembly 4, and a locking assembly 5. The protection cover 11 is fixedly connected above the protection seat 12, the first outlet pipe 13 is welded on the inclined surface of the protection cover 11, the second outlet pipe 14 is located at the rear side of the protection cover 11, the rotating drum 15 is located inside the protection cover 11 and the protection seat 12, the trigger assembly 4 and the locking assembly 5 are respectively located on the upper side and the lower side of the protection cover 11, and the protection cover 11 and the protection seat 12 can form a separation cavity during the extraction of phycocyanin. At the same time, the first outlet pipe 13 is used to guide the separated liquid from the upper side of the protection cover 11, and the second outlet pipe 14 is used to guide the separated solid residue.

[0031] In this embodiment: the trigger assembly 4 includes a sealing static ring 41, a sealing dynamic ring 42, and a rotating frame 43. A stepped guide port for introducing a suspension containing phycocyanin is provided at the center of the top of the protective cover 11. The sealing static ring 41 is fixed on the inner side of the stepped guide port of the protective cover 11. A through-type conical hole is provided at the center of the rotating drum 15, which corresponds to the stepped guide port of the protective cover 11, and a spiral slide groove is provided on the upper side of the tapered hole of the rotating drum 15. The lower end of the rotating frame 43 is sleeved on the upper side of the rotating drum 15, and a guide seat for cooperating with the slide groove of the rotating drum 15 is fixed at its lower end. The sealing dynamic ring 42 is installed on the top of the rotating frame 43, and the water flowing in from the stepped guide port on the top of the protective cover 11 enters the separation chamber formed by the protective cover 11 and the protective seat 12 respectively. At the same time, the high-speed rotation of the rotating drum 15 is used to drive the rotating frame 43 to push the sealing dynamic ring 42 upward along the spiral slide groove of the rotating drum 15, thereby sealing the sealing static ring 41 and the sealing dynamic ring 42.

[0032] In this embodiment: the locking assembly 5 includes a locking hole 51, a locking tongue groove 52, and a locking tongue 53. The protective cover 11 is provided with six locking holes 51 at the sealing static ring 41 and the sealing dynamic ring 42. The locking hole 51 of the protective cover 11 is provided with a locking tongue groove 52 at the lower end, and L-shaped guide holes are respectively provided on the upper and lower sides of the locking tongue groove 52. The locking tongue 53 is located inside the locking tongue groove 52 of the protective cover 11, and a tensioning spring is provided at the end of the locking tongue 53. When water enters the protective cover 11, water will also enter the locking tongue groove 52 through the locking hole 51. At the same time, water will also enter the L-shaped guide hole on the upper side of the locking tongue groove 52 and flow out from the L-shaped guide hole on the lower side of the locking tongue groove 52. At this time, the water pressure on the side of the locking tongue 53 connected to the tensioning spring is greater than the water pressure on the other end of the locking tongue 53. Therefore, the locking tongue 53 will extend outward along the locking tongue groove 52, and then the locking tongue 53 will be locked and fixed on the protective seat 12.

[0033] In this embodiment: the separation mechanism 3 includes a separation frame 31 and a separation disc 32. The separation frame 31 is sleeved on the outside of the drum 15, and a plurality of separation discs 32 are fixed on the outside of the separation frame 31 in a tower structure in sequence. The separation frame 31 is used to drive the separation disc 32 to rotate at a high speed with the drum 15, thereby separating phycocyanin from its suspension.

[0034] In this embodiment: the driving mechanism 2 includes a driving motor 21, a gear box 22, and a driving shaft 23. The gear box 22 is fixed under the protective seat 12. The driving shaft 23 extends from the top of the gear box 22 and passes through the protective seat 12 to be connected to the drum 15. The driving motor 21 is located on one side of the gear box 22. The driving shaft 23 is driven to rotate at a high speed by the rotating part of the driving motor 21 through the gear transmission in the gear box 22. The rotating drum 15 is driven to rotate at a high speed through the rotation of the driving shaft 23, thereby completing the separation driving force for the extraction of phycocyanin.

[0035] Working principle: When in use, first feed the phycocyanin suspension to be separated into the stepped guide port of the protective cover 11. At this time, the suspension will enter the conical hole of the drum 15, and then flow out through the bottom side of the drum 15 to enter the separation area formed by the protective cover 11 and the protective seat 12. In addition, part of the suspension will also pass through the locking hole 51 of the protective cover 11 and enter the lock tongue groove 52. At the same time, the suspension in the L-shaped guide hole on the upper side of the lock tongue groove 52 will flow out from the L-shaped guide hole on the lower side of the lock tongue groove 52 to the separation area. In this process, the pressure on one side of the lock tongue 53 connected to the tensioning spring is greater than the pressure on the other side of the lock tongue 53, and then the lock tongue 53 will extend outward, and then the tensioning spring of the lock tongue 53 will be stretched; when the lock tongue 53 is fully extended, the upper and lower ends of the lock tongue 53 will block the L-shaped guide holes on the upper and lower sides of the lock tongue groove 52, thereby preventing The suspension leaks out; then the rotating part of the driving motor 21 drives the driving shaft 23 to rotate at a high speed through the transmission of the gears in the gear box 22, and drives the drum 15 in the protective seat 12 to rotate at a high speed through the driving shaft 23, and then the drum 15 drives the separation frame 31 and the separation disc 32 to rotate at a high speed, and starts to separate the phycocyanin in the suspension. At this time, the solid residue will be discharged from the second outlet pipe 14, and the separated liquid will be discharged from the first outlet pipe 13; when the drum 15 rotates, due to the action of centrifugal force, the rotating frame 43 is thrown upward along the slide groove of the drum 15 through its guide seat, and then the sealing dynamic ring 42 and the sealing static ring 41 are sealed together, and at the same time, the thrown rotating frame 43 will block the upper end of the locking hole 51, at this time, the locking hole 51 and the locking tongue groove 52 are ensured to be in a sealed state, and then the locking tongue 53 can be prevented from retracting to play an automatic locking role.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
