Description

Technical Field

[0002] Collagen peptide is a protein extracted from animal connective tissue. It is rich in nutrients such as amino acids. Regular consumption can repair the body's skin cells, restore skin elasticity and radiance, delay aging, and moisturize hair. Since the raw materials contain a large amount of animal tissue impurities, they need to be purified and separated. This process requires the use of special separation and purification equipment.

[0003] In existing technical means, the purification process of collagen peptides usually involves injecting its raw materials into a specific main box, in which impurities in the raw liquid are removed by using precision filters. However, this method faces some significant problems in actual operation:

Once the filter component is clogged, it will not only hinder the smooth progress of the filtration process, but also significantly increase the difficulty of cleaning and maintenance. These blockages need to be frequently removed and handled, which not only increases the complexity of the operation, but also affects the working efficiency of the entire system;

The purified collagen peptide can pass through the perforated substrate without hindrance, and the dredging convex head can be sealed and inserted into the filter holes of the filter plate 3.

[0040] The sealing toothed disc 705 is provided with a through opening that can be aligned with the discharge port. When the discharge port on the side wall of the separation chamber is connected to the through opening of the sealing toothed disc 705, the purification path is closed and the recovery path is opened.

[0041] Reference Figure 2 and Figure 4-6 A displacement sensor 9 installed on the outer wall of the main box body 1 is provided on the side of the rack 701 away from the fixing seat 703. The displacement sensor 9 can detect the retraction distance of the rack 701. When the retraction amount of the rack 701 reaches the maximum displacement threshold preset by the displacement sensor 9, the displacement sensor 9 outputs the point determination information to the controller 10, and the controller 10 outputs the control of the pushing and discharging assembly 11;

The pulleys 1103 are connected by synchronous belt transmission. The output shaft of the reversible motor 1104 is coaxially connected to any pulley 1103. The base of the reversible motor 1104 is installed on the outer wall of the main box body 1. Under the self-spin transmission of the two screw rods 1102, the push plate 1101 threadedly sleeved thereon can move horizontally between the filter plate 3 and the closed partition 401 to speed up the waste discharge.

[0043] Working principle of the present invention:

[0044] The raw material to be purified is injected into the main box 1 through the feed hopper 12. The raw material is crushed by the pressure roller 2 in the rolling chamber, which can effectively destroy the cell wall and tissue structure, release the collagen molecules therein, and improve the subsequent purification efficiency. The crushed and rolled raw material is introduced into the separation chamber from the rolling chamber;

[0045] When the separation chamber is in a normal flow state, that is, the filter plate 3 is not blocked, the telescopic end of the electric push rod 606 is in a condensed state, and the push-pull rod 601 connected to its end slides to the farthest point to the right, and the lifting plate 604 carries the dredging member 5 and descends to the lowest point under the guidance of the guide head 603, so that the dredging protrusion on the top wall of the dredging member 5 is separated from the filter hole of the filter plate 3. At the same time, the push-pull rod 601 that slides to the farthest point to the right pulls the rack 701 forward to the maximum extension position via the rope 605, and the rack 701 sequentially drives the gear 704 and the sealing toothed disc 705, so that the sealing blade 402 and the sealing toothed disc 705 rotate, and then the feed port of the partition 401 is opened, and the discharge port of the side wall of the separation chamber is misaligned with the opening of the sealing toothed disc 705, that is, the discharge port is closed, that is, at this time, the purification path is unblocked, so that the raw materials introduced into the separation chamber can be separated and purified by the filter plate 3, and the collagen peptides therein can smoothly pass through the filter holes and drip into the discharge hopper 13, and finally converge to the collection device from the discharge hopper 13;

[0046] When the separation chamber is in an abnormal flow state, that is, the filter plate 3 is blocked, at this time, the telescopic end of the electric push rod 606 drives the push-pull rod 601 connected thereto to slide to the left to the nearest point, during which the push-pull rod 601 is pulled to the left along the axial cavity of the positioning seat 602 and the guide head 603 slides synchronously along the inclined slide groove of the lifting plate 604, forcing the lifting plate 604 to be subjected to an upward lifting force, and then the lifting plate 604 can move up along the slide rail of the side wall of the separation chamber and cooperate with the dredging member 5, so that the dredging protrusion on the top wall of the dredging member 5 is inserted into the filter hole of the filter plate 3, on the one hand, dredging the filter hole of the filter plate 3 and pushing impurities and dirt back to the upper layer of the filter plate 3, on the other hand, it also seals and blocks the filter hole, and suspends the separation and filtration of the raw materials. At the same time, during the sliding process of the push-pull rod 601 to the left, the distance between its end and the fixed seat 703 is As the distance between the push-pull rod and the rack 701 decreases gradually, the push-pull rod 601 gradually loses the traction force on the rack 701, and the spring 702 rebounds and resets. The spring 702 pulls the rack 701 to retract backwards. During the retraction of the rack 701, the gear 704 and the sealing toothed disc 705 are sequentially driven, so that the gear 704 drives the sealing blade 402 to rotate coaxially through the rotating shaft 403, and the sealing toothed disc 705 spins along the positioning shaft 706 until the push-pull rod 601 slides to the left to the nearest point. The sealing blade 402 closes the feed port, and the discharge port of the side wall of the separation chamber is aligned and connected with the opening of the sealing toothed disc 705. That is, at this time, the purification path is closed, and the recovery path is open, so that the dredging waste containing impurities is isolated between the filter plate 3 and the current limiting component 4, and can be discharged into the sedimentation box 801 through the opening of the sealing toothed disc 705;

[0047] The displacement sensor 9 can detect the retraction distance of the rack 701. When the retraction amount of the rack 701 reaches the maximum displacement threshold preset by the displacement sensor 9, it is determined that the switch from the purification path to the recovery path is made at this time. The displacement sensor 9 outputs point determination information to the controller 10. The controller 10 receives the point determination information and outputs a control instruction to the reversible motor 1104, controls the output shaft of the reversible motor 1104 to drive the pulley 1103 connected thereto to rotate, and the two pulleys 1103 are driven by a synchronous belt, so that the two screw rods 1102 connected to the pulleys 1103 rotate synchronously, causing the push plate 1101 threadedly sleeved thereon to move horizontally, thereby accelerating the waste discharge speed.

[0048] After the cleaning is completed, the equipment is restored and regains the ability to separate and purify collagen peptides.
