Description

Technical Field

[0001] This invention belongs to the field of collagen production technology, specifically relating to a device for separating and purifying natural collagen. Background Technology

[0002] Natural collagen is mostly found in animal connective tissues (skin, bones, tendons, ligaments, cartilage, etc.). It is a large protein molecule with a complete triple helix structure. In the collagen production process, enzymatic hydrolysis is often used to obtain hydrolyzed collagen (collagen peptides) that is more easily absorbed by the human body. In order to obtain collagen with a higher concentration, the hydrolyzed collagen needs to be purified.

[0003] For example, Chinese Patent Publication No. CN220802076U discloses a hydrolyzed collagen separation and purification device, comprising a main body with an internal cavity. A filter press is mounted on the top of the cavity. An inlet and an outlet are located on the side wall of the main body, communicating with the cavity. The outlet is located at the bottom of the cavity, and the inlet is above the outlet. A pump is mounted on the top of the main body, connected to a suction pipe inside the cavity. A drain pipe is connected to the pump. This device separates macromolecular collagen and water using an ultrafiltration membrane, increasing the concentration of the hydrolyzed collagen solution. It eliminates the need for heating to evaporate the water in the solution, preventing thermal denaturation of the hydrolyzed collagen solution and thus protecting product quality.

[0004] As described in the prior art of the aforementioned patent, the structure is too rigid, making it inconvenient to replace the filter membrane. Utility Model Content

[0005] The purpose of this invention is to provide a device for separating and purifying natural collagen, which is divided into multiple units to facilitate the replacement of filter membranes.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A natural collagen separation and purification device includes a feed cylinder, a filter cylinder, and a discharge cylinder arranged from top to bottom. A pressure plate is slidably mounted inside the feed cylinder, and a feed inlet is provided on the pressure plate. A feed pipe is connected to the upper end of the feed inlet. A filter membrane is disposed inside the filter cylinder, and a first discharge port is provided on one side of the filter cylinder. The bottom of the first discharge port is slightly higher than the height of the filter membrane inside the filter cylinder. The filter membrane is laid on a protrusion inside the filter cylinder, and its upper surface is fixed by a pressure ring. A second discharge port is provided on one side of the discharge cylinder.

[0008] In a preferred embodiment, the feed cylinder, the filter cylinder, and the discharge cylinder are stacked together in sequence, and the filter cylinder is detachable from the feed cylinder and the discharge cylinder.

[0009] In a preferred embodiment, a second telescopic rod is connected above the pressure plate, the upper end of the second telescopic rod is fixedly connected to the outside of the feed cylinder, and a guide rod is connected above the pressure plate. The guide rod is slidably mounted on the sliding sleeve, and the sliding sleeve is fixedly connected to the feed cylinder.

[0010] In a preferred embodiment, a discharge valve is installed on the discharge port one, and a discharge valve is installed on the discharge port two.

[0011] In a preferred embodiment, a telescopic rod is connected to the outer side of the discharge cylinder, and the upper end of the telescopic rod is fixedly connected to the feed cylinder.

[0012] In a preferred embodiment, a base is installed at the bottom of the discharge cylinder, and the base is hinged to the discharge cylinder via a hinge point. A telescopic rod three is also hinged to the lower end of the discharge cylinder, and the other end of the telescopic rod three is hinged to the base.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model divides the entire device into three sections: the feed cylinder, the filter cylinder, and the discharge cylinder. When replacing the filter membrane, the position between the feed cylinder and the discharge cylinder is adjusted first, which allows the filter cylinder to be separated from the two, making it easier to replace the filter membrane inside the filter cylinder and making the maintenance of the equipment more convenient.

[0015] This utility model is designed so that the discharge cylinder is hinged to the base via a hinge point. The tilting of the feed cylinder, filter cylinder, and discharge cylinder relative to the base is adjusted by the extension and retraction of the telescopic rod three. This causes the feed cylinder, filter cylinder, and discharge cylinder as a whole to tilt towards discharge port one and discharge port two, making it easier to empty the internal raw materials completely and reducing the residue of internal substances.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0026] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0027] Please see the appendix Figures 1 to 3As shown, this utility model provides a natural collagen separation and purification device, including a feed cylinder 1, a filter cylinder 2, and a discharge cylinder 3 arranged from top to bottom. A pressure plate 11 is slidably arranged inside the feed cylinder 1, and a feed inlet 12 is provided on the pressure plate 11. The upper end of the feed inlet 12 is connected to a feed pipe 14. A filter membrane 21 is provided inside the filter cylinder 2, and a discharge port 24 is provided on one side of the filter cylinder 2. The bottom of the discharge port 24 is slightly higher than the height of the filter membrane 21 inside the filter cylinder 2. The filter membrane 21 is laid on the protrusion 22 inside the filter cylinder 2, and the top of the filter membrane 21 is fixed by a pressure ring 23. A discharge port 31 is provided on one side of the discharge cylinder 3.

[0028] In the separation and purification of collagen, firstly, control valve 13 on the inlet 12 is opened to inject the raw material into the feed cylinder 1 through the inlet 12. Then, control valve 13 is closed, and pressure is applied to the collagen injected into the feed cylinder 1 by operating the pressure plate 11. This forces the water in the collagen to pass through the filter membrane 21 in the filter cylinder 2 into the discharge cylinder 3, while the collagen remains in the feed cylinder 1. This achieves the separation of collagen from water, thereby improving the quality of the collagen. The separated water is then discharged through outlet 2 31, and the collagen material is discharged through outlet 1 24. When the filter membrane 21 in the filter cylinder 2 needs to be replaced, the vertical distance between the feed cylinder 1 and the discharge cylinder 3 is first adjusted, then the filter cylinder 2 is removed from between the two, and then the filter membrane 21 in the filter cylinder 2 is replaced to improve the convenience of operation. The feed cylinder 1, the filter cylinder 2 and the discharge cylinder 3 are stacked together in sequence, and the filter cylinder 2 is detachable from the feed cylinder 1 and the discharge cylinder 3.

[0029] In this embodiment, the entire device is divided into three sections: feed cylinder 1, filter cylinder 2, and discharge cylinder 3. When replacing the filter membrane 21, the position between the feed cylinder 1 and the discharge cylinder 3 is adjusted first, which allows the filter cylinder 2 to be separated from the two, thus facilitating the replacement of the filter membrane 21 inside the filter cylinder 2 and making the maintenance of the equipment more convenient.

[0030] Above the pressure plate 11, there is also a telescopic rod 15. The upper end of the telescopic rod 15 is fixedly connected to the outside of the feed cylinder 1. Above the pressure plate 11, there is also a guide rod 16. The guide rod 16 is slidably mounted on the sliding sleeve 17. The sliding sleeve 17 is fixedly connected to the feed cylinder 1.

[0031] By extending the telescopic rod 15 downwards, the pressure plate 11 can be moved downwards. The downward movement of the pressure plate 11 can apply pressure to the collagen injected into the feed cylinder 1, which facilitates better filtration. When the pressure plate 11 moves up and down, it will drive the guide rod 16 to move along the sliding sleeve 17. The connection between the guide rod 16 and the sliding sleeve 17 makes the up and down movement of the pressure plate 11 more stable.

[0032] A discharge valve 25 is installed on discharge port 1 24, and a discharge valve 32 is installed on discharge port 2 31;

[0033] In this embodiment, discharge valve 25 is used to control the opening and closing of discharge port 24, and discharge valve 32 is used to control the opening and closing of discharge port 31. During the separation and filtration process, discharge valve 25 is in a closed state, and discharge valve 32 can be adjusted to an open state. The closed state of discharge valve 25 is to prevent unfiltered collagen from flowing out along discharge port 24. After the separation and purification are completed, discharge valve 25 is opened so that the purified collagen is discharged along discharge port 24.

[0034] Please see Figure 3 and Figure 5 As shown, a telescopic rod 5 is connected to the outside of the discharge cylinder 3, and the upper end of the telescopic rod 5 is fixedly connected to the feed cylinder 1.

[0035] By extending the telescopic rod 5, the feed cylinder 1 can be moved upward, separating the discharge cylinder 3 from the feed cylinder 1. Then, the filter cylinder 2 can be removed to facilitate the replacement of the filter membrane 21 inside the filter cylinder 2. When replacing the filter membrane 21, remove the bolts used to fix the boss 22 and the pressure ring 23, then remove the pressure ring 23, remove the old filter membrane 21, lay the new filter membrane 21 on the boss 22, press the pressure ring 23 on the filter membrane 21, and fix it with bolts to complete the replacement of the filter membrane 21. Then, stack the filter cylinder 2 on the discharge cylinder 3, and then retract the telescopic rod 5 so that the discharge cylinder 3 and the feed cylinder 1 clamp the filter cylinder 2 in the middle to form a whole, and then a new filtration operation can be carried out.

[0036] Please see Figure 4 As shown, a base 4 is installed at the bottom of the discharge cylinder 3. The base 4 and the discharge cylinder 3 are hinged together through a hinge point 41. A telescopic rod 42 is also hinged to the lower end of the discharge cylinder 3. The other end of the telescopic rod 42 is hinged to the base 4.

[0037] In this embodiment, in order to more thoroughly discharge the filtered collagen and water, with the discharge valve 1 25 and discharge valve 2 32 open, the telescopic rod 3 42 is extended, causing the feed cylinder 1, filter cylinder 2 and discharge cylinder 3 to rotate around the hinge point 41 and the base 4, so that the feed cylinder 1, filter cylinder 2 and discharge cylinder 3 tilt toward the discharge port 1 24 and discharge port 2 31, making it easier to empty the internal materials more thoroughly.

[0038] In this embodiment, telescopic rod 1 5, telescopic rod 2 15, and telescopic rod 3 42 are all electric telescopic rods, and are all controlled by a control device. The control device for the telescopic rods is existing technology, and will not be described in detail here.

[0039] The working principle of this utility model is as follows: When separating and purifying collagen, firstly, the control valve 13 on the feed port 12 is opened, and the raw material is injected into the feed cylinder 1 through the feed port 12. Then, the control valve 13 is closed, and the pressure plate 11 is pressed down to apply pressure to the collagen injected into the feed cylinder 1. This causes the water in the collagen to pass through the filter membrane 21 in the filter cylinder 2 and enter the discharge cylinder 3, while the collagen can remain in the feed cylinder 1. This achieves the separation of collagen and water, thereby improving the quality of the collagen. Then, the separated water is discharged through the discharge port 21, and the collagen is discharged through the discharge port 24.

[0040] When it is necessary to replace the filter membrane 21 in the filter cylinder 2, first adjust the vertical distance between the feed cylinder 1 and the discharge cylinder 3, then remove the filter cylinder 2 from between the two, and then replace the filter membrane 21 in the filter cylinder 2, which improves the convenience of operation.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
