Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to a nanofiltration device for peptide extraction. Background Technology

[0002] A nanofiltration device for peptide extraction is a key piece of equipment in the health food industry. Raw materials include soybeans, corn, wheat, cowhide, cow bones, sea cucumbers, and oysters. This device utilizes advanced nanotechnology to efficiently extract bioactive peptide molecules from these natural raw materials, providing crucial technical support for health food production. In the health food industry, peptides, as an important nutrient, have attracted significant attention due to their unique bioactivity and health benefits. The nanofiltration device, with its unique nanoscale pore structure, can effectively screen for target peptide molecules while removing impurities and ineffective components.

[0003] In existing technologies, nanofiltration equipment plays a crucial role in peptide extraction. Currently, commercially available rinsing equipment has limitations in its pipe fixing methods. These devices typically require specific fixing components to tightly connect one end of the pipe to the filtration equipment. However, when faced with filter tubes of different diameters, these fixing components often fail to achieve compatibility and adaptation. These fixing components cannot effectively adapt to filter tubes of various sizes, thus limiting the applicability and reducing the equipment's versatility. This not only increases costs but also reduces operational efficiency. In terms of maintenance and cleaning, the incompatibility of the fixing components also leads to maintenance difficulties. Improper fixing methods can cause physical damage to the filter tubes, especially during repeated installation and disassembly. This damage shortens the lifespan of the filter tubes and further increases operating costs. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nanofiltration device for peptide extraction.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a nanofiltration device for peptide extraction, comprising an installation frame, a filter tube fixed to the surface of the installation frame, an inner filter tube on the inner wall of the filter tube, a side support plate fixed to one side of the installation frame, a water pump fixed to the top of the side support plate, a cleaning pipe fixed to one end of the water pump, a fixed coarse pipe fixed to one end of the cleaning pipe, an arc-shaped T-groove formed on the circumference of the fixed coarse pipe, a slip ring slidably connected to the inner wall of the arc-shaped T-groove, hollow moving teeth fixed to the circumference of the slip ring, arc-shaped grooves formed in a circular array on the surface of the hollow moving teeth, a track disk fixed to the circumference of the fixed coarse pipe, an inverted T-groove formed in a circular array on one side of the track disk, a T-piece slidably connected to the inner wall of the inverted T-groove, the T-piece... One end of the component is fixed with a sliding column, the circumference of which is slidably connected to the inner wall of the arc groove. The other end of the inverted T-groove is fixed with a residual ring petal. The track disk is rotatably connected to a drive gear, the surface of which meshes with the surface of a hollow moving tooth. A shaft is fixed to one side of the drive gear, and the shaft is connected to a motor. The motor is fixed to the circumference of the fixed coarse tube by a fixing seat. In the prior art, nanofiltration equipment plays an important role in the peptide extraction process. Currently, the flushing equipment available on the market has certain limitations in the way the pipeline is fixed. These devices usually require specific fixing components to tightly connect one end of the pipeline to the filtration equipment. However, when faced with filter tubes of different diameters, the fixing components are often difficult to achieve compatibility and adaptation. These fixing components cannot effectively adapt to different diameters. The availability of filter tubes of various sizes limits the applicability and versatility of the equipment, increasing costs and reducing operational efficiency. In terms of maintenance and cleaning, incompatible fixing components also lead to difficulties. Improper fixing methods can cause physical damage to the filter tubes, especially during repeated installation and disassembly, shortening their lifespan and further increasing operating costs. To address these issues, this invention employs a residual ring flap installation method. When cleaning is required, the operator first inserts a specially designed fixing thick tube into one end of the filter tube. This thick tube has a specific mechanical structure for subsequent expansion and fixing operations. After insertion, the operator starts the motor, which begins to rotate. This drives the driving gear to rotate clockwise. The rotation of the driving gear is transmitted to another gear rotating counterclockwise through a meshing mechanism, thereby activating the expansion mechanism. The arc groove plays a key role in this process. As the gear rotates, the arc groove actuates the sliding pin, causing it to move along the inner wall towards the end of the arc groove away from the center. This movement propels the T-piece, causing the residual ring petals to gradually expand. The expansion of the residual ring petals continues until they are in close contact with the inner wall of the filter tube. At this point, due to the pressure, the contact between the residual ring petals and the inner wall of the filter tube becomes firm, achieving stable fixation. The advantage of this design lies in its high adaptability. Regardless of the diameter of the filter tube, this mechanical expansion and fixation mechanism can provide a stable and reliable connection.This means that workers can use the same set of tools to clean filter tubes of different sizes, greatly improving the equipment's versatility and cleaning efficiency. Furthermore, this mechanical fixing method reduces the need for additional fixing parts, simplifies the operation process, reduces the likelihood of errors, and ultimately expands the equipment's applicability.

[0006] Preferably, the T-piece has an arc-shaped triangle fixed to its side, one side of which is fixed to the inner circumferential surface of the residual ring petal. In the prior art, the residual ring petal plays a crucial role in the operation of nanofiltration equipment, ensuring a stable connection between the inner wall of the filter tube and the cleaning equipment. However, when the equipment starts supplying water for the cleaning process, the impact of the water flow adversely affects the residual ring petal. The impact force of the water flow causes the residual ring petal to vibrate. This vibration is relatively slight in the initial stage, but as the cleaning process continues, especially when the equipment runs for a long time, the cumulative effect of the vibration will gradually become apparent. Prolonged vibration will negatively affect the connection stability between the residual ring petal and the T-piece. Due to the presence of vibration, the fixing effect between the residual ring petal and the T-piece will gradually weaken. This weakening is due to loosening of the connection or a decrease in structural strength caused by material fatigue. As the fixing effect further decreases, the connection between the residual ring petal and the T-piece will completely... Failure can ultimately lead to component detachment. To address this issue, this invention employs an arc-end triangle installation method. When the equipment starts operating and vibrates, the arc-end triangle's stability kicks in. The vibration force is transmitted along the equipment's frame and ultimately reaches the arc-end triangle. Due to its triangular structure, the vibration force is effectively dispersed and absorbed at the arc-end triangle. This dispersion and absorption reduces the impact on the connection points, significantly lowering the risk of loosening. The arc-end triangle's design is inspired by the principle of triangle stability; in geometry, a triangle is one of the most stable structures. This mechanism consists of three sides, each precisely calculated and designed to ensure its length and angle can withstand vibration forces from different directions. These three sides converge at the connection point, forming a robust vertex, enabling the entire structure to maintain high stability when facing external forces, thus extending the equipment's lifespan.

[0007] Preferably, a pipe clamp seat is fixed to the top of the side plate, and the inner wall of the pipe clamp seat is nested with the circumference of the cleaning pipe. In the prior art, when the water pump starts, it pushes water through the cleaning pipe. If the momentum of the water flow is large enough, it will have a strong impact on the cleaning pipe. This impact will cause the cleaning pipe to shake and sway at its connection with the water pump. This shaking and swaying is the result of the direct action of the water flow force and the combined action of the vibration in the system. The fasteners used are not enough to withstand long-term vibration and impact, and the stability of the connection will gradually weaken. If the connection between the cleaning pipe and the water pump fails completely, the cleaning pipe will fall off or break. Such an accident will not only damage the equipment, but also injure the operators and interrupt the production process. In addition, the leaked water will invade other production equipment or circuits, causing more widespread damage. To address such problems, this utility model uses the method of installing a pipe clamp seat to solve the problem, thereby restricting the connection end of the cleaning pipe by the pipe clamp seat, preventing the cleaning pipe from shaking, and improving the production safety.

[0008] Preferably, the bottom of the mounting frame is fixed with a chamfered pad to buffer the collision between the mounting frame and the ground, reduce the impact of noise and vibration, and improve the user experience.

[0009] Preferably, a sturdy ladder foot is fixed to the top of the chamfered pad, and the inner wall of the sturdy ladder foot is fixed to the bottom of the mounting frame, which improves the fixing effect and extends the service life of the equipment.

[0010] Preferably, the bottom of the chamfered pad is provided with a cross-shaped anti-slip groove to prevent the equipment from slipping and improve the stability of the equipment.

[0011] Preferably, the periphery of the residual ring petal is covered with a rubber layer to increase friction and improve the performance of the equipment.

[0012] Beneficial effects:

[0013] 1. In existing technologies, nanofiltration equipment plays a crucial role in peptide extraction. Currently, commercially available rinsing equipment has limitations in its pipe fixing methods. These devices typically require specific fixing components to tightly connect one end of the pipe to the filtration equipment.

In addition, this mechanical fixation method reduces the need for additional fixing parts, simplifies the operation process, reduces the possibility of errors, and achieves the effect of improving the applicability of the equipment.

[0014] 2. In existing technologies, the residual ring valve plays a crucial role in the operation of nanofiltration equipment, ensuring a stable connection between the inner wall of the filter tube and the cleaning device. However, when the equipment begins water supply for the cleaning process, the impact of the water flow adversely affects the residual ring valve. The impact force of the water flow causes the residual ring valve to vibrate. This vibration is relatively minor in the initial stage, but as the cleaning process continues, especially when the equipment runs for a long time, the cumulative effect of the vibration gradually becomes apparent. Prolonged vibration negatively impacts the connection stability between the residual ring valve and the T-piece. Due to the vibration, the fixing effect between the residual ring valve and the T-piece gradually weakens. This weakening is due to loosening of the connection or a decrease in structural strength caused by material fatigue. As the fixing effect further decreases, the connection between the residual ring valve and the T-piece will completely fail, ultimately leading to the detachment of the component. To address this... This invention addresses the problem by using an arc-end triangle installation method. When the equipment starts operating and vibrates, the stability of the arc-end triangle begins to function. The vibration force is transmitted along the equipment frame and finally reaches the arc-end triangle. Due to its triangular structure, the vibration force is effectively dispersed and absorbed at the arc-end triangle. This dispersion and absorption reduces the impact on the connection points, thus significantly reducing the risk of loosening. The design of the arc-end triangle is inspired by the principle of triangle stability; in geometry, a triangle is one of the most stable structures. This mechanism consists of three sides, each precisely calculated and designed to ensure its length and angle can withstand vibration forces from different directions. These three sides converge at the connection point, forming a solid vertex, enabling the entire structure to maintain high stability when facing external forces, thereby improving the service life of the equipment.

[0015] 3. In the prior art, when the water pump starts, it pushes water through the cleaning pipe. If the momentum of the water flow is large enough, it will have a strong impact on the cleaning pipe. This impact will cause the cleaning pipe to shake and sway at its connection with the water pump. This shaking and swaying is the result of the direct action of the water flow force and the combined effect of vibrations within the system. The fasteners used are insufficient to withstand long-term vibration and impact, and the stability of the connection will gradually weaken. If the connection between the cleaning pipe and the water pump completely fails, the cleaning pipe will fall off or break. Such accidents will not only damage the equipment but also injure the operators and interrupt the production process. In addition, the leaked water will infiltrate other production equipment or circuits, causing more widespread damage. To address this problem, this utility model uses a pipe clamp seat to solve the problem, thereby restricting the connection end of the cleaning pipe and preventing the cleaning pipe from shaking, thus improving production safety.

Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

[0027] Reference Figure 1-6A nanofiltration device for peptide extraction includes a mounting frame 1, a filter tube 101 fixed to the surface of the mounting frame 1, an inner filter tube 102 on the inner wall of the filter tube 101, a side support plate 105 fixed to one side of the mounting frame 1, a water pump 106 fixed to the top of the side support plate 105, a cleaning tube 107 fixed to one end of the water pump 106, a fixed coarse tube 2 fixed to one end of the cleaning tube 107, an arc T-groove 201 formed on the circumference of the fixed coarse tube 2, a slip ring 202 slidably connected to the inner wall of the arc T-groove 201, hollow moving teeth 203 fixed on the circumference of the slip ring 202, arc grooves 204 formed in a circular array on the surface of the hollow moving teeth 203, a track disk 205 fixed on the circumference of the fixed coarse tube 2, and an inverted T-groove 206 formed in a circular array on one side of the track disk 205. A T-piece 207 is slidably connected to the inner wall of the T-groove 206. A sliding column 208 is fixed to one end of the T-piece 207, and the circumference of the sliding column 208 is slidably connected to the inner wall of the arc groove 204. A residual ring petal 209 is fixed to the other end of the inverted T-groove 206. A drive gear 2010 is rotatably connected to the track disk 205. The surface of the drive gear 2010 meshes with the surface of the hollow moving tooth 203. A shaft is fixed to one side of the drive gear 2010, and the shaft is connected to a motor 2011. The motor 2011 is fixed to the circumference of the fixed coarse tube 2 via a fixing seat 2012. In the peptide extraction process, nanofiltration equipment plays an important role. Currently, the flushing equipment available on the market has certain limitations in the way the pipeline is fixed. These devices usually require specific fixing components to connect one end of the pipeline to the flow path. While filtration equipment is tightly integrated, the fixing components often struggle to achieve compatibility when dealing with filter tubes of varying diameters. These components cannot effectively adapt to filter tubes of different sizes, thus limiting the equipment's applicability and reducing its versatility. This not only increases costs but also reduces operational efficiency. Furthermore, the incompatibility of the fixing components leads to maintenance difficulties, and improper fixing methods can cause physical damage to the filter tubes, especially during repeated installation and disassembly. This damage shortens the filter tube's lifespan and further increases operating costs. The solution is to use a residual ring flap 209, which allows for easy cleaning by inserting a specially designed fixing thick tube 2 into the filter tube body 101. At the end, this thick tube has a specific mechanical structure for subsequent expansion and fixing operations. After insertion, the operator starts the motor 2011, which begins to rotate and drives the drive gear 2010 to rotate clockwise. The rotation of the drive gear 2010 is transmitted to another gear rotating counterclockwise through a meshing mechanism, thereby activating the expansion mechanism. The arc groove 204 plays a key role in this process. As the gear rotates, the arc groove 204 actuates the sliding column 208, causing it to move along the inner wall towards the end of the arc groove 204 away from the center. This movement pushes the T-piece 207 to move, causing the residual ring petals 209 to gradually expand. The expansion of the residual ring petals 209 continues until they are in close contact with the inner wall of the filter tube body 101. At this point, due to the pressure,The contact between the residual ring petal 209 and the inner wall of the filter tube 101 becomes firm, achieving stable fixation. The advantage of this design lies in its high adaptability. No matter how the diameter of the filter tube 101 changes, this mechanical expansion and fixing mechanism can provide a stable and reliable connection. This means that workers can use the same set of tools to clean filter tubes of different sizes, greatly improving the versatility of the equipment and the efficiency of cleaning work. In addition, this mechanical fixing method reduces the need for additional fixing parts, simplifies the operation process, reduces the possibility of errors, and achieves the effect of improving the applicability of the equipment. A curved-end triangle 301 is fixed to the side of T-piece 207. One side of the curved-end triangle 301 is fixed to the inner circumferential surface of the residual ring petal 209. During the operation of the nanofiltration device, the residual ring petal 209 plays a crucial role, ensuring a stable connection between the inner wall of the filter tube 101 and the cleaning device. However, when the device starts supplying water for the cleaning process, the impact of the water flow will adversely affect the residual ring petal 209. The impact force of the water flow will cause the residual ring petal 209 to vibrate. This vibration is relatively slight in the initial stage, but as the cleaning process continues, especially when the device runs for a long time, the cumulative effect of the vibration will gradually become apparent. Long-term vibration will negatively affect the connection stability between the residual ring petal 209 and T-piece 207. Due to the presence of vibration, the fixing effect between the residual ring petal 209 and T-piece 207 will gradually weaken. This weakening is due to loosening of the connection or a decrease in structural strength caused by material fatigue. As the fixing effect further decreases, the connection between the residual ring petal 209 and T-piece 207 will become increasingly unstable. The connection between parts 207 would completely fail, ultimately leading to component detachment. This is addressed by installing an arc-end triangle 301. When the equipment starts operating and vibrates, the stability of the arc-end triangle 301 begins to function. Vibrational forces are transmitted along the equipment frame and ultimately reach the arc-end triangle 301. Due to its triangular structure, the vibrational forces are effectively dispersed and absorbed at the arc-end triangle 301. This dispersion and absorption reduces the impact on the connection points, significantly reducing the risk of loosening. The design of the arc-end triangle 301 is inspired by the stability principle of triangles; in geometry, a triangle is one of the most stable structures. This mechanism consists of three sides, each precisely calculated and designed to ensure its length and angle can withstand vibrational forces from different directions. These three sides converge at the connection point, forming a robust vertex, enabling the entire structure to maintain high stability when facing external forces, thus extending the equipment's lifespan. The residual ring petal 209 is covered with a rubber layer to increase friction and improve equipment performance.

[0028] A pipe clamp seat 3 is fixed to the top of the side plate 105. The inner wall of the pipe clamp seat 3 is nested with the circumference of the cleaning pipe 107. When the water pump 106 starts, it pushes water through the cleaning pipe 107. If the momentum of the water flow is large enough, it will have a strong impact on the cleaning pipe 107. This impact will cause the cleaning pipe 107 to shake and sway at its connection with the water pump 106. This shaking and swaying is the result of the direct action of the water flow force and the combined action of the vibration in the system. The fasteners used are not enough to withstand long-term vibration and impact, and the stability of the connection will gradually weaken. If the connection between the cleaning pipe 107 and the water pump 106 fails completely, the cleaning pipe 107 will fall off or break. Such an accident will not only damage the equipment, but also injure the operators and interrupt the production process. In addition, the leaked water will invade other production equipment or circuits, causing more widespread damage. The method of installing the pipe clamp seat 3 solves this problem. It restricts the connection end of the cleaning pipe 107 by the pipe clamp seat 3, prevents the cleaning pipe 107 from shaking, and improves the production safety. A chamfered corner pad 104 is fixed to the bottom of the mounting frame 1 to cushion the impact between the mounting frame 1 and the ground, reducing the impact of noise and vibration and improving the user experience. A sturdy ladder foot 103 is fixed to the top of the chamfered corner pad 104. The inner wall of the sturdy ladder foot 103 is fixed to the bottom of the mounting frame 1 to improve the fixation effect and extend the service life of the equipment. A cross-shaped anti-slip groove is provided on the bottom of the chamfered corner pad 104 to prevent the equipment from slipping and improve the stability of the equipment.

[0029] The working principle of this utility model is as follows: When cleaning is required, the operator first inserts a specially designed fixed thick tube 2 into one end of the filter tube 101. This thick tube has a specific mechanical structure for subsequent expansion and fixing operations. After insertion, the operator starts the motor 2011, which begins to rotate and drives the drive gear 2010 to rotate clockwise. The rotation of the drive gear 2010 is transmitted to another gear rotating counterclockwise through a meshing mechanism, thereby activating the expansion mechanism. The arc groove 204 plays a key role in this process. As the gear rotates, the arc groove 204 moves... The sliding column 208 moves along the inner wall toward the end of the arc groove 204 away from the center. This movement pushes the T-piece 207 to move, causing the residual ring petals 209 to gradually expand. The expansion of the residual ring petals 209 continues until they are in close contact with the inner wall of the filter tube 101. At this point, due to the pressure, the contact between the residual ring petals 209 and the inner wall of the filter tube 101 becomes firm, achieving stable fixation. The advantage of this design is its high adaptability. No matter how the diameter of the filter tube 101 changes, this mechanical expansion and fixation mechanism can provide a stable and reliable connection.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
