DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 9 The present invention provides a technical solution: a marine biological collagen functional peptide extraction device, comprising a reactor 11, a feeding device 14 and a discharging device 15, wherein the inner wall of the reactor 11 is provided with a quantitative mechanism 12, and the quantitative mechanism 12 is used to quantitatively inject a decomposition enzyme into the reactor 11; the reactor 11 is provided with a crushing mechanism, and the crushing mechanism is used to crush the raw materials in the reactor 11, and the crushing mechanism includes a plurality of wall-breaking knives 13, and the wall-breaking knives 13 can be retracted into the crushing mechanism for cleaning and storage after the crushing is completed; the reactor 11 is provided with a temperature control mechanism, and the temperature control mechanism is used to adjust the internal temperature of the reactor 11.

[0030] First, the raw materials are fed into the reactor 11 through the feeding device 14, and then the crushing mechanism is started to crush the raw materials; after the raw materials are crushed, the wall-breaking knives 13 used to cut the raw materials in the crushing mechanism are uniformly retracted into the crushing mechanism, separated from the raw materials and the subsequently injected decomposition substances, and the wall-breaking knives 13 are cleaned in the crushing mechanism to prevent the substances in the raw materials from corroding or adhering to the wall-breaking knives 13; then the quantitative mechanism 12 quantitatively injects decomposition substances such as decomposition enzymes into the reactor 11, and at the same time, the temperature control mechanism continuously adjusts and controls the internal temperature of the reactor 11 during this process, so as to provide a temperature environment for the decomposition enzyme to efficiently decompose, and finally the decomposed raw materials are discharged from the reactor 11 through the discharging device 15, and subsequent purification and packaging processes are carried out.

[0031] The present invention allows the wall-breaking knife 13 to be retracted into the crushing mechanism for cleaning and storage, so that the crushing mechanism is arranged in the reactor 11 to avoid long-term contact with the raw materials, and the wall-breaking knife 13 can be cleaned during the operation of the raw material decomposition equipment.

[0032] Furthermore, the crushing mechanism includes a motor 21, which is fixedly connected to the upper end of the reactor 11, and the lower end of the motor 21 is fixedly connected to a vertically arranged transmission shaft 22, and the transmission shaft 22 is sleeved with a sleeve 23. The outer wall of the sleeve 23 is vertically arrayed with multiple groups of tracks 24, and each group of the tracks 24 is distributed on the sleeve 23 in a circular array with the axis of the sleeve 23, and the tracks 24 extend to the sleeve 23, and each of the tracks 24 is slidably connected to an independent wall-breaking knife 13, and the sleeve 23 is provided with a sealing mechanism at the corresponding track 24, and the sealing mechanism is used to separate the reactor 11 from the inner cavity of the sleeve 23; the part of the track 24 located in the sleeve 23 is provided with a driving mechanism and a cleaning mechanism, and the driving mechanism is used to control the wall-breaking knife 13 to slide on the track 24, and the cleaning mechanism is used to clean the wall-breaking knife 13.

[0033] When the equipment cuts the raw materials, the driving mechanism drives the wall-breaking knife 13 to slide along the track 24 toward the outside of the sleeve 23 until the wall-breaking knife 13 is completely extended out of the sleeve 23. Correspondingly, the transmission shaft 22 accelerates its rotation at this time, and drives the sleeve 23 and the wall-breaking knife 13 to rotate at high speed, so that the wall-breaking knife 13 cuts the raw materials; then when the raw materials are cut, the transmission shaft 22 rotates in the opposite direction and the rotation decreases. At the same time, the driving mechanism drives the wall-breaking knife 13 to slide along the track 24 toward the inside of the sleeve 23, so that the wall-breaking knife 13 is retracted into the sleeve 23. During this process, the cleaning mechanism cleans the wall-breaking knife 13 that is retracted into the sleeve 23; at the same time, the track 24 continues to rotate with the transmission shaft 22. During this process, the track 24 acts as a stirring rod to continuously stir and mix the raw materials to ensure the decomposition efficiency.

[0034] Furthermore, the sealing mechanism includes a sealing block 31 embedded in the side wall of the sleeve 23, and the sealing block 31 is penetrated by a avoidance hole for the movement of the wall-breaking knife 13. Both ends of the wall-breaking knife 13 are fixedly connected with sealing plates 32; when the sealing plate 32 is located in the avoidance hole, it can seal with the sealing block 31.

[0035] The sealing sheets 32 at both ends of the wall-breaking knife 13 can engage with the avoidance holes on the sealing block 31 when the wall-breaking knife 13 is fully extended or fully retracted into the sleeve 23, so that the liquid in the raw material cannot penetrate into the sleeve 23 through the avoidance holes.

[0036] Furthermore, the cleaning mechanism includes a mounting rod 41 fixedly connected to the track 24, the mounting rod 41 is close to the inner wall of the sleeve 23, the end of the mounting rod 41 is fixedly connected to a spray rack 42, the spray rack 42 is close to one end of the track 24 and is respectively fixedly connected to two nozzles 43, the two nozzles 43 are respectively located on both sides of the wall-breaking knife 13, the spray rack 42 is connected to an external water source, and the spray rack 42 is used to control the two nozzles 43 to spray both sides of the wall-breaking knife 13 when the wall-breaking knife 13 slides into the sleeve 23.

[0037] As the wall-breaking knife 13 slides into the sleeve 23 , the spray rack 42 controls the two spray heads 43 to spray both sides of the wall-breaking knife 13 to rinse the wall-breaking knife 13 .

[0038] Furthermore, the temperature control mechanism includes an air pump 51, which is fixedly connected to the upper end of the inner wall of the sleeve 23. The air pump 51 is used to spray temperature-controllable air downward. A plurality of one-way valves 52 are provided at the lower end of the sleeve 23.

[0039] The air pump 51 sprays temperature-controlled air downward, allowing the air to enter the lower end of the reactor 11 through the one-way valve 52, and then pass through the raw materials upward to leave the reactor 11. In this process, the air and the raw materials undergo efficient heat exchange, so that the temperature of the raw materials can be quickly adjusted by the air, further enhancing the reaction speed of the temperature control of the equipment, and further ensuring that the decomposition enzyme can remain at an appropriate temperature for reaction, thereby improving the decomposition efficiency of the equipment; at the same time, the nozzle 43 sprays both sides of the wall-breaking knife 13, and in the process of flushing the wall-breaking knife 13, the air sprayed downward by the air pump 51 can bring out the water and raw material residue in the flushing process through the one-way valve 52, and at the same time blow dry the residual water droplets on the wall-breaking knife 13 to keep the sleeve 23 clean.

[0040] Furthermore, the driving mechanism includes a mounting frame 61, which is fixedly connected to the side wall of the track 24, and a synchronous belt 62 is arranged on the mounting frame 61. A slider 63 is fixedly connected to the end of the sealing plate 32 near the transmission shaft 22, and a connecting rod 64 is fixedly connected to the side wall of the slider 63. The connecting rod 64 is fixedly connected to the side wall of the synchronous belt 62, and the transmission shaft 22 is fixedly connected to a synchronous wheel 65, and the synchronous wheel 65 is meshed with the synchronous belt 62. The sleeve 23 is provided with a regulating mechanism, and the regulating mechanism is used to lock the sleeve 23 and the transmission shaft 22 after the wall breaking knife 13 is fully extended or retracted into the sleeve 23, and to lock the sleeve 23 and the reactor 11 when the wall breaking knife 13 is not fully extended or retracted into the sleeve 23.

[0041] When the equipment is ready to cut the raw materials, the regulating mechanism locks the sleeve 23 and the reactor 11, so that during the rotation of the transmission shaft 22, the transmission shaft 22 and the sleeve 23 rotate relative to each other. During this process, the transmission shaft 22 rotates forward and drives the synchronous wheel 65 to rotate forward relative to the synchronous belt 62. Further, the synchronous wheel 65 drives the synchronous belt 62 to rotate forward, so that the synchronous belt 62 drives the slider 63 to slide along the track 24 to the outside of the sleeve 23, and then drives the wall-breaking knife 13 to the outside of the sleeve 23 until the wall-breaking knife 13 completely slides out of the sleeve 23. At this time, the regulating mechanism unlocks the sleeve 23 and the reactor 11, and locks the sleeve 23 and the transmission shaft 22, so that the rotation of the transmission shaft 22 drives the sleeve 23 and the sleeve 23 The wall-breaking knife 13 on it rotates; when the raw materials are cut and need to be continuously stirred, the regulating mechanism locks the sleeve 23 and the reactor 11, and unlocks the sleeve 23 and the transmission shaft 22, and the transmission shaft 22 reverses. Correspondingly, the synchronous wheel 65 drives the synchronous belt 62 to reverse, and drives the slider 63 to slide along the track 24 into the sleeve 23, thereby driving the wall-breaking knife 13 to slide into the sleeve 23 until the wall-breaking knife 13 is completely retracted into the sleeve 23. At this time, the regulating mechanism unlocks the sleeve 23 and the reactor 11, and locks the sleeve 23 and the transmission shaft 22, so that the transmission shaft 22 rotates to drive the sleeve 23 and the track 24 on the sleeve 23 to rotate, so that the track 24 continuously stirs the raw materials.

[0042] Furthermore, the regulating mechanism includes a nut 71, which is fixedly connected to the upper end of the sleeve 23, and a threaded sleeve 72 is fixedly connected to the side wall of the transmission shaft 22. The nut 71 is threadedly connected to the threaded sleeve 72, and the lower end of the transmission shaft 22 passes through the lower end of the sleeve 23 and is rotatably connected to the bottom of the reactor 11. A first solenoid valve is externally connected between the transmission shaft 22 and the sleeve 23, and a second solenoid valve is externally connected between the sleeve 23 and the reactor 11. The activation of the first solenoid valve can lock the transmission shaft 22 and the sleeve 23, and the activation of the second solenoid valve can prevent the sleeve 23 and the reactor 11 from rotating relative to each other; a displacement sensor is externally connected between the nut 71 and the threaded sleeve 72, and the displacement sensor can control the activation of the first solenoid valve and the second solenoid valve according to the relative displacement between the nut 71 and the threaded sleeve 72.

[0043] When the equipment controls the wall-breaking knife 13 to extend or retract into the sleeve 23, the second solenoid valve is started and the first solenoid valve is closed. When the equipment controls the wall-breaking knife 13 to cut the raw materials or controls the track 24 to stir the raw materials, the second solenoid valve is closed and the first solenoid valve is opened. In this process, when the wall-breaking knife 13 extends out of the sleeve 23, the nut 71 and the threaded sleeve 72 rotate relative to each other, so that the nut 71 drives the sleeve 23 to move downward to reduce the gap between the lower end of the sleeve 23 and the reactor 11, thereby avoiding material piling at the lower end of the sleeve 23 (in this process, the raw materials in the gap between the lower end of the sleeve 23 and the reactor 11 can be blown out by the air pump 51 and blown to the side of the sleeve 23 for cutting); when the wall-breaking knife 13 is retracted into the sleeve 23, the corresponding nut 71 and the threaded sleeve 72 rotate in opposite directions, so that the nut 71 drives the sleeve 23 to move upward, so that the gap between the lower end of the sleeve 23 and the reactor 11 is increased, thereby increasing the contact area between the sleeve 23 and the raw materials, and enhancing the stirring effect of the equipment.

[0044] Furthermore, a group of the wall-breaking knives 13 are all arranged obliquely on the vertical plane and the horizontal plane, and an adjacent group of the wall-breaking knives 13 are all arranged obliquely in opposite directions on the vertical plane and the horizontal plane.

[0045] By using the inclined wall-breaking knife 13 and the track 24, the wall-breaking knife 13 and the track 24 are rotated to drive the surrounding raw materials to flow in a vertical direction, so that the raw materials can be cut or stirred more evenly.
