Description

Technical Field

[0001] This utility model relates to the field of active substance extraction technology, specifically to a rotary filtration device for efficient extraction of fish collagen peptides. Background Technology

[0002] Fish collagen peptides are small molecule polypeptides obtained from fish collagen through targeted enzymatic hydrolysis. They possess bioactivities such as promoting skin repair and enhancing bone and joint health. The extraction process typically includes key steps such as raw material pretreatment, enzymatic hydrolysis, centrifugation, and filtration purification. In addition to the target peptides, the extract after enzymatic hydrolysis also contains unreacted proteins, fats, pigments, and enzymatic hydrolysis byproducts. Therefore, the filtration process is crucial. Physical retention can effectively remove large molecular impurities, insoluble particles, and colloidal substances, ensuring the purity and stability of the final product.

[0003] Existing filtration devices mostly employ static filters or simple centrifugal structures. Traditional static filters are easily clogged by high-viscosity enzymatic hydrolysates, requiring frequent shutdowns for cleaning, resulting in low processing efficiency. Centrifugal filtration structures lack a dynamic slag removal mechanism, leading to filter cake accumulation, which creates filtration resistance, increases energy consumption, and necessitates shutdowns for filter cake cleaning after prolonged use, further contributing to low filtration efficiency. Therefore, those skilled in the art provide a rotary filtration device for high-efficiency extraction of fish collagen peptides to address the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a rotary filtration device for efficient extraction of fish collagen peptides, thereby solving the problems mentioned in the background section of the prior art.

[0005] This utility model provides the following technical solution: a rotary filtration device for efficient extraction of fish collagen peptides, comprising a storage tank for collecting raw liquid, wherein a processing component for rotary filtration of the raw liquid is installed on the inner wall of the storage tank, and a removal component for scraping off the raw liquid is installed in the processing component.

[0006] As a preferred embodiment of the above technical solution, the processing component includes a motor, a partition plate, and a support frame. The motor is fixedly installed at the center of the lower end of the storage tank, the partition plate is fixedly connected to the lower part of the inner wall of the storage tank, and the support frame is fixedly connected to the upper part of the inner wall of the storage tank.

[0007] As a preferred embodiment of the above technical solution, a rotating cylinder is rotatably mounted at the center of the partition plate and the support frame. A filter screen is provided on the side wall of the rotating cylinder, and a mounting frame is fixedly connected to the lower part of the inner wall of the rotating cylinder. The output end of the motor passes through the lower end of the storage tank and is fixedly connected to the center of the lower end of the mounting frame.

[0008] As a preferred embodiment of the above technical solution, a connecting frame is fixedly connected to the upper part of the inner wall of the rotating cylinder, an external toothed ring is fixedly connected to the upper end of the connecting frame, and a spiral rod is rotatably sleeved at the center of the connecting frame. The upper end of the spiral rod is rotatably connected to the top center of the inner wall of the storage tank, and the spiral rod is rotatably mounted on the rotating cylinder.

[0009] As a preferred embodiment of the above technical solution, a spur gear is fixedly sleeved on the upper part of the outer wall of the spiral rod, and a gear set is rotatably connected to the top of the inner wall of the storage tank. The gear and the outer gear ring at the lower part of the gear set mesh with each other, and the gear and the spur gear at the upper part of the gear set mesh with each other. The number of teeth on the outer gear ring is less than the number of teeth on the gear set, and the number of teeth on the spur gear is the same as the number of teeth on the gear set.

[0010] As a preferred embodiment of the above technical solution, the removal component includes a connecting rod, which is fixedly connected to one side of the lower end of the support frame, and a scraper is fixedly connected to one side of the connecting rod, with the scraper facing the filter screen.

[0011] As a preferred embodiment of the above technical solution, a material injection pipe is connected to one side of the upper end of the storage tank, and the material injection pipe is connected to the inside of the rotating cylinder. A sewage discharge pipe is connected to one side of the lower end of the storage tank, and a material discharge pipe is connected to one side of the side wall of the storage tank near the bottom. The material discharge pipe is located above the partition plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The processing unit is driven by a motor to rotate the rotating drum. At the same time, the meshing transmission between the external gear ring and the gear set causes the screw rod to move axially. The rotating drum and the screw rod rotate in the same direction, but the speed of the screw rod is less than that of the rotating drum. The raw liquid entering the storage tank will fall onto the screw rod. The rotating screw rod throws the raw liquid onto the inner wall of the filter screen. The filter screen is used to achieve centrifugal filtration of the raw liquid. At the same time, the screw rod and the rotating drum rotate relative to each other. The screw rod can promote the discharge of filter cake along the spiral direction, which significantly improves the filtration efficiency and reduces the risk of clogging.

[0014] 2. The scraper of the removal component simultaneously scrapes away the filtered raw liquid outside the filter screen during the filtration process. This effectively prevents high-concentration raw liquid from forming a residue layer on the filter screen surface due to adhesion, ensuring that the filtration interface remains clean at all times, thereby improving the overall filtration efficiency of fish collagen peptides.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution: a rotary filtration device for efficient extraction of fish collagen peptides, including a storage tank 1 for collecting the original liquid, a processing component 2 for rotary filtration of the original liquid installed on the inner wall of the storage tank 1, and a removal component 3 for scraping off the original liquid installed in the processing component 2.

[0023] Furthermore, the processing component 2 can achieve centrifugal filtration of the raw liquid, and at the same time promote the discharge of filter cake from the bottom of the storage tank 1, which significantly improves the filtration efficiency and reduces the risk of clogging. The removal component 3 simultaneously scrapes off the filtered raw liquid outside the processing component 2 during the filtration process, which can effectively prevent high concentration raw liquid from forming a retention layer on the surface of the processing component 2 due to adhesion, ensuring that the filtration interface is always kept clean, thereby improving the overall filtration efficiency of fish collagen peptides.

[0024] As one implementation method in this embodiment, please refer to Figures 2-3 As shown, the processing component 2 includes a motor 201, a partition plate 202, and a support frame 203. The motor 201 is fixedly installed at the center of the lower end of the storage tank 1, the partition plate 202 is fixedly connected to the lower part of the inner wall of the storage tank 1, and the support frame 203 is fixedly connected to the upper part of the inner wall of the storage tank 1.

[0025] A rotating cylinder 204 is rotatably mounted at the center of the partition plate 202 and the support frame 203. A filter screen 205 is provided on the side wall of the rotating cylinder 204. An installation frame 206 is fixedly connected to the lower part of the inner wall of the rotating cylinder 204. The output end of the motor 201 passes through the lower end of the storage tank 1 and is fixedly connected to the center of the lower end of the installation frame 206.

[0026] A connecting frame 207 is fixedly connected to the upper part of the inner wall of the rotating cylinder 204. An external toothed ring 208 is fixedly connected to the upper end of the connecting frame 207. A spiral rod 209 is rotatably sleeved at the center of the connecting frame 207. The upper end of the spiral rod 209 is rotatably connected to the top center of the inner wall of the storage tank 1. The spiral rod 209 is rotatably set in the rotating cylinder 204.

[0027] A spur gear 210 is fixedly sleeved on the upper part of the outer wall of the spiral rod 209. A gear set 211 is rotatably connected to the top of the inner wall of the storage tank 1. The gear at the lower part of the gear set 211 meshes with the external gear ring 208, and the gear at the upper part of the gear set 211 meshes with the spur gear 210. The number of teeth of the external gear ring 208 is less than the number of teeth of the gear set 211, and the number of teeth of the spur gear 210 is the same as the number of teeth of the gear set 211.

[0028] Further, the raw liquid to be filtered is injected into the storage tank 1 through the injection pipe 4. The motor 201 drives the rotating drum 204 to rotate at high speed. The gear set 211 consists of two gears, which are arranged vertically. The gears are driven by the meshing of the external gear ring 208 with the lower gear of the gear set 211. Subsequently, the upper gear of the gear set 211 drives the spur gear 210 to rotate, thereby causing the screw rod 209 and the rotating drum 204 to rotate in the same direction. Since the number of teeth of the external gear ring 208 is less than the number of teeth of the gears in the gear set 211, the rotational speed of the screw rod 209 is lower than that of the rotating drum 204, resulting in relative rotation between the screw rod 209 and the rotating drum 204. The screw 209 has an additional axial propulsion function. The injected raw liquid falls onto the rotating screw 209 and is thrown towards the inner wall of the filter screen 205 by centrifugal force. The filter screen 205 is fixedly connected to the inner wall of the rotating cylinder 204. The microporous structure of the filter screen 205 realizes solid-liquid separation. Small molecule collagen peptides pass through the filter screen 205 into the upper space of the partition plate 202 in the storage tank 1 and are discharged through the discharge pipe 6. The filter residue is pushed to the lower end of the rotating cylinder 204 by the axial movement of the screw 209, so that the filter residue is collected in the lower space of the partition plate 202 in the storage tank 1 and finally discharged through the drain pipe 5, thereby significantly improving the filtration efficiency and reducing the risk of clogging.

[0029] As one implementation method in this embodiment, please refer to Figure 2 and Figure 4As shown, the removal component 3 includes a connecting rod 301, which is fixedly connected to one side of the lower end of the support frame 203. A scraper 302 is fixedly connected to one side of the connecting rod 301, and the scraper 302 faces the filter screen 205.

[0030] Furthermore, the scraper 302 is fixed in place with the support frame 203, and there is a small distance between the scraper 302 and the filter screen 205. This avoids direct contact between the scraper 302 and the filter screen 205, preventing the scraper 302 from damaging the filter screen 205. When the filter screen 205 rotates, the scraper 302 simultaneously scrapes off a certain thickness of filtered original liquid from the outside of the filter screen 205. This effectively prevents high-concentration original liquid from forming a residue layer on the surface of the filter screen 205 due to adhesion, ensuring that the filtration interface always remains clean, thereby improving the overall filtration efficiency of fish collagen peptides.

[0031] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, a material injection pipe 4 is connected to one side of the upper end of the storage tank 1, and the material injection pipe 4 is connected to the inside of the rotating drum 204. A sewage discharge pipe 5 is connected to one side of the lower end of the storage tank 1, and a discharge pipe 6 is connected to one side of the side wall of the storage tank 1 near the bottom. The discharge pipe 6 is located above the partition plate 202.

[0032] Furthermore, the raw liquid is precisely introduced into the rotating drum 204 through the injection pipe 4 to achieve efficient centrifugal filtration. The drain pipe 5 facilitates the rapid discharge of filter residue, while the discharge pipe 6 is located above the separator plate 202 to ensure that the filtered collagen peptide solution is physically isolated from the filter residue, avoiding secondary pollution. At the same time, the fluid path is optimized, significantly improving the separation and purification efficiency and simplifying the operation process.

[0033] Working principle: The raw liquid to be filtered is injected into the storage tank 1 through the injection pipe 4. The motor 201 drives the rotating drum 204 to rotate at high speed. At the same time, the external gear ring 208 meshes with the gear at the lower part of the gear set 211, and then the gear at the upper part of the gear set 211 drives the spur gear 210 to rotate. This causes the screw rod 209 and the rotating drum 204 to rotate in the same direction. Since the number of teeth of the external gear ring 208 is less than the number of teeth of the gear set 211, the rotation speed of the screw rod 209 is lower than that of the rotating drum 204, resulting in relative rotation between the screw rod 209 and the rotating drum 204. This gives the screw rod 209 an additional axial propulsion function. The injected raw liquid falls on the rotating screw rod 209 and is thrown against the inner wall of the filter screen 205 by centrifugal force. The filter screen 205 rotates. The microporous structure of the filter screen enables solid-liquid separation. Small molecule collagen peptides pass through the filter screen 205 into the upper space of the partition plate 202 in the storage tank 1 and are discharged through the discharge pipe 6. The filter residue is pushed to the lower end of the rotating cylinder 204 by the axial movement of the screw rod 209, so that the filter residue is collected in the lower space of the partition plate 202 in the storage tank 1 and finally discharged through the drain pipe 5. This significantly improves the filtration efficiency and reduces the risk of clogging. When the filter screen 205 rotates, the scraper 302 is fixed with the support frame 203. The scraper 302 simultaneously scrapes off the filtered original liquid outside the filter screen 205, which can effectively prevent high concentration original liquid from forming a retention layer on the surface of the filter screen 205 due to adhesion, ensuring that the filtration interface is always kept clean, thereby improving the overall filtration efficiency of fish collagen peptides.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
