Description

Technical Field

[0001] This utility model relates to the field of chemical separation technology, specifically a multi-stage filter for efficient recovery of collagen solution. Background Technology

[0002] In today's biotechnology and beauty industries, the demand for collagen solutions continues to rise due to their unique bioactivity and broad application prospects. Collagen solutions obtained from biological sources often contain various impurities in their initial state, including unreacted raw material particles, cell debris, and other biological macromolecules, which seriously affect the purity and quality of the collagen solution and thus limit its application in high-end fields.

[0003] However, traditional collagen solution filtration technologies often employ single filters or simple filtration combinations, failing to effectively remove impurities of varying particle sizes. Common single-layer filters can only intercept larger particles, rendering them ineffective against fine impurities. This results in the final recovered solution failing to meet the extremely high purity standards of industries such as high-end cosmetics and medical-grade biomaterials. Some devices attempting multi-stage filtration suffer from problems such as filter clogging, uneven solution flow, and low filtration efficiency due to unreasonable structural design. Filter clogging not only interrupts the filtration process but also significantly increases production and time costs due to frequent filter cleaning and replacement. In terms of equipment maintenance, existing filters are mostly monolithic structures, making internal component repair or replacement complex and requiring time-consuming and labor-intensive work by professionals using specialized tools. To address these issues, we offer a high-efficiency multi-stage filter for collagen solution recovery. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage filter for efficient collagen solution recovery, in order to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a multi-stage filter for high-efficiency collagen solution recovery, including a base plate, a base fixedly connected to the upper surface of the base plate, a cylindrical barrel fixedly connected to the upper end of the base, a discharge pipe provided on the side wall of the base, a servo motor fixedly connected to the upper end of the cylindrical barrel, a feed pipe provided on the side wall of the cylindrical barrel, a rotating rod fixedly connected to the output end of the servo motor, the lower end of the rotating rod penetrating the upper surface of the cylindrical barrel and extending into the interior, a stirring blade fixedly connected to the surface of the rotating rod, a common filter screen fixedly connected to the inner wall of the cylindrical barrel, multiple springs fixedly connected to the lower surface of the common filter screen, the other end of the multiple springs fixedly connected to the same ceramic filter screen, a positive toothed ring fixedly connected to the lower surface of the ceramic filter screen, multiple first support rods fixedly connected to the surface of the rotating rod, the other end of the multiple first support rods fixedly connected to the same negative toothed ring, multiple second support rods fixedly connected to the surface of the rotating rod, the other end of the multiple second support rods fixedly connected to a ceramic filter barrel, and a discharge valve fixedly connected to the right end of the discharge pipe.

[0006] Preferably, the bottom of the cylinder is funnel-shaped and tilted at an angle of thirty-five degrees.

[0007] Preferably, the left end of the discharge pipe penetrates the surface of the base and connects to the lower surface of the cylinder, and the left end of the discharge pipe is connected to the interior of the cylinder.

[0008] Preferably, the left end of the feed pipe penetrates the surface of the barrel and extends into the interior of the barrel.

[0009] Preferably, the ordinary filter screen is sleeved on the surface of the rotating rod, and the ordinary filter screen is located below the stirring blade.

[0010] Preferably, the positive toothed ring and the negative toothed ring are matched, and the second support rod and the ceramic filter barrel are located below the negative toothed ring.

[0011] Preferably, the upper end of the barrel is provided with a slot, and a maintenance cover is threadedly connected to the inner wall of the slot.

[0012] Preferably, the pore size of the ceramic filter screen is smaller than the pore size of the ceramic filter barrel.

[0013] This invention provides an improved multi-stage filter for efficient collagen solution recovery, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this utility model, this multi-stage filter, achieves highly efficient filtration of collagen solutions through its unique structural design. During the filtration process, the material first undergoes preliminary interception through a common filter screen to remove larger particulate impurities. Subsequently, under the action of stirring blades, the solution passes through a ceramic filter screen for further fine filtration. Next, the solution enters a ceramic filter tank for a second filtration. The setting of different pore sizes forms a gradient filtration, with each layer ensuring higher purity of the final recovered collagen solution, meeting the requirements of various application scenarios with strict requirements for the purity of collagen solutions.

[0015] Secondly, this utility model filter is designed with ease of maintenance in mind, thereby reducing operating costs. The slot at the top of the cylindrical barrel is threaded to the maintenance cover. When a malfunction occurs inside the equipment or when cleaning or replacement of components such as the filter screen is required, the maintenance cover can be easily unscrewed to inspect and maintain the internal structure. In addition, the modular design of the equipment makes the disassembly and installation of each component relatively simple. For example, the ceramic filter screen is connected to the ordinary filter screen by a spring, and replacement can be completed without complicated operations. At the same time, each filter component is made of durable materials. For example, the ceramic filter screen and ceramic filter barrel have good wear resistance and corrosion resistance, which extends the service life of the equipment, reduces the cost of frequent component replacement, and improves the overall cost performance of the equipment.

[0016] Thirdly, this utility model uses a servo motor to drive a rotating rod, which in turn drives the stirring blades and the reverse toothed ring to rotate synchronously. The stirring blades can continuously stir the solution during the filtration process, ensuring that the solution passes evenly through each stage of the filter screen. This avoids situations where the solution flow rate is too slow or stagnant in local areas, greatly improving the overall filtration efficiency. The meshing structure of the positive and negative toothed rings not only achieves vibration-based anti-clogging of the ceramic filter screen, but also makes the material transport during the filtration process smoother through ingenious mechanical transmission. At the same time, the bottom of the cylindrical tank is designed as a funnel shape with a 35-degree inclination angle, and the discharge pipe is directly connected to the bottom of the cylindrical tank, which facilitates the rapid discharge of the filtered solution and reduces the residual time of the solution in the equipment. This achieves efficient collagen solution recovery operations, providing strong support for large-scale production applications and significantly increasing the amount of collagen solution recovered per unit time.

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model provides an improved multi-stage filter for efficient collagen solution recovery. The technical solution of this utility model is as follows:

[0027] like Figure 1 - Figure 5 As shown, a multi-stage filter for high-efficiency collagen solution recovery includes a base plate 1, a base 2 fixedly connected to the upper surface of the base plate 1, a cylindrical barrel 3 fixedly connected to the upper end of the base 2, a discharge pipe 4 provided on the side wall of the base 2, a servo motor 5 fixedly connected to the upper end of the cylindrical barrel 3, a feed pipe 6 provided on the side wall of the cylindrical barrel 3, a rotating rod 7 fixedly connected to the output end of the servo motor 5, the lower end of the rotating rod 7 penetrating the upper surface of the cylindrical barrel 3 and extending into the interior, a stirring blade 8 fixedly connected to the surface of the rotating rod 7, and a common filter screen 9 fixedly connected to the inner wall of the cylindrical barrel 3. Multiple springs 10 are fixedly connected to the lower surface of the ordinary filter screen 9. The other end of the multiple springs 10 is fixedly connected to the same ceramic filter screen 11. A positive toothed ring 12 is fixedly connected to the lower surface of the ceramic filter screen 11. Multiple first support rods 13 are fixedly connected to the surface of the rotating rod 7. The other end of the multiple first support rods 13 is fixedly connected to the same reverse toothed ring 14. Multiple second support rods 15 are fixedly connected to the surface of the rotating rod 7. The other end of the multiple second support rods 15 is fixedly connected to a ceramic filter barrel 16. A discharge valve 17 is fixedly connected to the right end of the discharge pipe 4.

[0028] Furthermore, the bottom of the cylindrical barrel 3 is funnel-shaped and tilted at a 35-degree angle. The funnel-shaped bottom design combined with the 35-degree tilt angle can effectively guide the filtered collagen solution to converge towards the discharge pipe 4, preventing the solution from accumulating at the bottom of the cylindrical barrel, accelerating the solution discharge speed, significantly improving the smoothness of the overall filtration operation, while reducing solution residue and improving the solution recycling rate.

[0029] Furthermore, the left end of the discharge pipe 4 penetrates the surface of the base 2 and connects to the lower surface of the cylinder 3, and the left end of the discharge pipe 4 is connected to the inside of the cylinder 3. Through the structure that the discharge pipe 4 is directly connected to the bottom of the cylinder 3, it is ensured that the filtered solution can be discharged from the equipment through the shortest path, reducing the residence time of the solution in the pipe, reducing the risk of secondary contamination of the solution, simplifying the discharge process, and improving the operating efficiency of the equipment.

[0030] Furthermore, the left end of the feed pipe 6 penetrates the surface of the cylinder 3 and extends into the interior of the cylinder 3. The design of the feed pipe 6 extending deep into the interior of the cylinder 3 allows the collagen raw material slurry to be accurately delivered to the working range of the stirring blade 8, which facilitates the stirring blade 8 to quickly stir and mix the material, promotes uniform dispersion of the material, and provides a stable and uniform raw material input for the subsequent filtration process, which is conducive to improving the consistency of the overall filtration effect.

[0031] Furthermore, a common filter screen 9 is fitted onto the surface of the rotating rod 7, and the common filter screen 9 is located below the stirring blade 8. Because the common filter screen 9 is located below the stirring blade 8, during the process of stirring the solution, the liquid flow generated by stirring can be used to quickly guide larger particles of impurities to the common filter screen 9 for interception, avoiding excessive diffusion of impurities in the solution, improving the initial filtration efficiency, and at the same time protecting the ceramic filter screen 11 below from the impact of large particles, thus extending the service life of the ceramic filter screen 11.

[0032] Furthermore, the positive gear ring 12 matches the negative gear ring 14, and the second support rod 15 and the ceramic filter barrel 16 are located below the negative gear ring 14. Through the matching design of the positive gear ring 12 and the negative gear ring 14, the rotating rod 7 can drive the negative gear ring 14 when it rotates, thereby driving the meshing positive gear ring 12, causing the ceramic filter screen 11 to vibrate. This effectively prevents impurities from accumulating and clogging the filter screen, ensuring continuous and efficient filtration.

[0033] Furthermore, a slot 18 is provided at the upper end of the cylinder 3, and a maintenance cover 19 is threadedly connected to the inner wall of the slot 18. The threaded connection design between the slot 18 and the maintenance cover 19 greatly facilitates the internal maintenance of the equipment. When it is necessary to repair the internal structure of the equipment, simply unscrew the maintenance cover 19 to directly access the internal structure without having to disassemble the equipment on a large scale, thus reducing the difficulty and cost of maintenance. It also makes it easier to detect and solve problems that occur during the operation of the equipment in a timely manner, ensuring the stable operation of the equipment.

[0034] Furthermore, the pore size of the ceramic filter screen 11 is smaller than that of the ceramic filter barrel 16. This difference in pore size forms a gradient filtration structure. The ceramic filter screen 11 first performs relatively fine filtration on the solution, intercepting smaller particulate impurities. Then, the ceramic filter barrel 16 further filters the solution based on the existing filtration, ensuring that the final recovered collagen solution reaches a higher purity standard, meeting the strict requirements of different industries for the purity of collagen solution, and broadening the application range of the equipment.

[0035] Working principle: In operation, the servo motor 5 is started first, and the recovered collagen is fed into the cylindrical barrel 3 through the feed pipe 6. The servo motor 5 then drives the rotating rod 7 to rotate, which in turn drives the stirring blade 8, the first support rod 13, the reverse toothed ring 14, the second support rod 15, and the ceramic filter barrel 16 to rotate. When the reverse toothed ring 14 rotates, it will intersect with the positive toothed ring 12. The positive toothed ring 12 then drives the ceramic filter screen 11 to vibrate up and down. The recovered collagen will first be roughly filtered through the ordinary filter screen 9, and then fall onto the ceramic filter screen 11. When the ceramic filter screen 11 vibrates, it will undergo a second filtration, and then fall into the ceramic filter barrel 16. The rotating ceramic filter barrel 16 will then filter the collagen three times. After opening the discharge valve 17, the filtered collagen can flow out from the discharge pipe 4. Finally, when the machine needs maintenance or internal cleaning, the maintenance cover 19 can be opened.

[0036] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
