Description

Technical Field

[0001] The utility model belongs to the technical field of bone material processing equipment, and particularly relates to a homogenizing and stirring device for bone collagen fibers. Background Art

[0002] Bone collagen fibers refer to fibrous structures formed by collagen or collagen proteins. In the structure of bones, collagen fibers are contained in both bone and cartilage tissues. Collagen fibers play a structural framework role in bone and cartilage tissues. The arrangement direction of the fibers has a certain pattern and has a certain resistance to pressure. Due to the existence of collagen fibers, the hardness of bones and cartilage is enhanced. Experiments have proved that bone collagen fibers play a great role in improving the vitality of white blood cells and thus enhancing the immune function and improving allergic constitutions. Great expectations are placed on the treatment of rheumatoid arthritis and the prevention and treatment of immune function diseases with living bone collagen. In addition, bone collagen fibers can also be processed into artificial blood vessels, skin wrinkles removal, contact lenses, artificial skin and other materials through modern biotechnology.

[0003] Effective extraction of bone collagen fibers is the basis for obtaining the aforementioned materials. The extraction of bone collagen fiber materials usually includes the acquisition and cleaning of bone materials, the cutting of bone materials, and the chemical treatment of bone materials, etc. During the processing, it is necessary to homogenize and stir the bone collagen fibers to improve the homogeneity of the bone collagen fiber liquid. It is necessary to develop and design a stirring device for bone collagen fiber homogenization. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a homogenizing and stirring device for bone collagen fibers, which improves the efficiency of homogenizing and stirring and ensures the effect of homogenizing and stirring.

[0005] The technical solution adopted by the utility model is: a homogenizing and stirring device for bone collagen fibers, including a homogenizing tank supported by a frame, with a sealed bottom and an open top. A tank bottom stirrer is installed at the center of the bottom wall of the homogenizing tank, and a discharge pipe with a discharge valve is also installed on the bottom wall of the homogenizing tank; a top support of the tank is installed at the top of the homogenizing tank, a shaft seat is installed at the center of the top support, and a stirring shaft is installed in the shaft seat. An upper stirring impeller is installed on the upper part of the stirring shaft, and a lower stirring impeller is installed at the bottom. It also includes a driving component for driving the stirring shaft to rotate and a feed pipe with a feed valve extending into the interior of the homogenizing tank; a ring-shaped flushing component for spraying the inner wall of the homogenizing tank is installed inside the open top of the homogenizing tank.

[0006] Preferably, the driving component includes a driven belt pulley installed at the upper end of the stirring shaft. A stirring motor is installed on the side of the frame, and a driving belt pulley is installed on the output shaft of the stirring motor. The driving belt pulley and the driven belt pulley are connected by a transmission belt; a tensioner for tensioning the transmission belt is also included.

[0007] Preferably, the flushing assembly includes an annular water distribution pipe installed and fixed at the bottom of the top support of the tank. A plurality of nozzles with jet directions facing downward and outward are installed on the annular water distribution pipe. It further includes a liquid inlet connector, which includes a base fixedly connected to the top support of the tank and a water inlet joint installed on the base. The outer end of the water inlet joint is connected to a water source through a pipeline, and the inner end is connected to the annular water distribution pipe through a pipeline.

[0008] Preferably, the bottom stirrer of the tank includes a base fixedly connected to the bottom wall of the homogenizing tank. Above the base, a rotating seat is installed through a gland. A gear ring is installed at the bottom of the rotating seat. It further includes a driving gear meshing with the gear ring. The driving gear is driven by a driving motor installed at the bottom of the base. A plurality of helical blades are installed on the rotating seat at equal angular intervals in the circumferential direction.

[0010] The advantages and positive effects of the present utility model are:

[0011] The present utility model provides a bone collagen fiber homogenizing and stirring device with a reasonable structural design. By arranging an upper stirring impeller and a lower stirring impeller driven to rotate by a driving assembly in the tank body of the homogenizing tank, strong stirring and mixing of the bone collagen fiber slurry in the tank are achieved. By installing a bottom stirrer of the tank at the bottom of the homogenizing tank, auxiliary stirring and homogenizing of the bone collagen fiber slurry in the tank are achieved. Usually, a single form of stirring impeller is likely to form a regular laminar flow of the bone collagen fiber slurry in the tank, resulting in a deteriorated homogenizing effect. The bottom stirrer installed at the bottom of the tank can effectively disrupt the aforementioned regular laminar flow, thereby improving the efficiency and effect of the homogenizing and stirring of the bone collagen fiber slurry.

[0012] By installing a flushing assembly inside the open top of the homogenizing tank, after the bone collagen fiber slurry that has been homogenized and stirred in the tank is discharged through the discharge pipe, the inner wall of the homogenizing tank can be spray-flushed by the flushing assembly, promoting the shedding of the bone collagen fibers adhering to the inner wall of the homogenizing tank. At the same time, the flushing assembly is also used for thorough cleaning of the homogenizing tank after a single bone collagen fiber homogenizing and stirring. Description of the Drawings

[0019] To further understand the inventive content, features and effects of the present utility model, the following embodiments are hereby given for detailed description.

[0020] Please refer to Figure 1 , the bone collagen fiber homogenizing and stirring device of the present utility model includes a homogenizing tank 4 supported by a frame 1, with a sealed bottom and an open top. A bottom tank stirrer 3 is installed at the center of the bottom wall of the homogenizing tank 4, and a discharge pipe 2 with a discharge valve is also installed on the bottom wall of the homogenizing tank 4.

[0021] A tank top support 8 is installed at the top of the homogenizing tank 4. A shaft seat 11 is installed at the center of the tank top support 8, and a stirring shaft 19 is installed in the shaft seat 11. An upper stirring impeller 18 is installed at the upper part of the stirring shaft 19, and a lower stirring impeller 20 is installed at the bottom. It also includes a driving assembly for driving the rotation of the stirring shaft 19 and a feed pipe 15 with a feed valve 16 extending into the interior of the homogenizing tank 4.

[0022] The original pulp of the bone collagen fiber slurry is injected into the interior of the homogenizing tank 4 through the feed pipe 15. After homogenizing and stirring, it is discharged from the homogenizing tank 4 through the discharge pipe 2 and enters the next processing equipment. The discharge valve provided on the discharge pipe 2 and the feed valve 16 provided on the feed pipe 15 are respectively used to manually control the on / off of the discharge pipe 2 and the feed pipe 15.

[0023] The stirring shaft 19, upper stirring impeller 18 and lower stirring impeller 20 driven by the driving component are used to strongly stir and mix the collagen fiber slurry in the tank, and the bottom stirrer 3 arranged at the bottom of the tank is used to assist in homogenizing and stirring the collagen fiber slurry in the tank. Usually, the method of using the stirring impeller for stirring and mixing is relatively single, and it is easy to form regular laminar flow inside the homogenizing tank. In this embodiment, the bottom stirrer 3 arranged is used to break the above-mentioned regular laminar flow effect, promote the efficiency of homogenizing and stirring, and improve the effect of homogenizing and stirring.

[0024] As shown in the figure, the frame 1 includes four columns, a middle support frame 5 is installed in the middle of the four columns, and a top support frame 6 is installed at the top. The middle part of the homogenizing tank 4 is fixedly connected to the middle support frame 5, and the top is fixedly connected to the top support frame 6.

[0025] Furthermore, the homogenizing tank 4 includes a tank body located above and a conical bottom located at the bottom of the tank body. The bottom stirrer 3 and the discharge pipe 2 are installed on the conical bottom. There are flange plates at the bottom of the tank body and the top of the conical bottom. These two flange plates are connected by bolts and a gasket is arranged between them. The function of this structure is that after a certain period of use, it is necessary to thoroughly clean the inside of the homogenizing tank 4. At this time, the tank body and the conical bottom can be disassembled, which is conducive to the above-mentioned thorough cleaning work.

[0026] Please refer to Figure 4 , it can be seen that:

[0027] The driving component includes a driven pulley 10 installed at the upper end of the stirring shaft 19. A stirring motor 17 is installed on the side of the frame 1, and a driving pulley 14 is installed on the output shaft of the stirring motor 17. The driving pulley 14 and the driven pulley 10 are connected by a transmission belt 13. As shown in the figure, the top support frame 6 has an outward extension section. An inclined support is arranged between the middle part on the same side of the frame 1 and the outer end of this extension section to ensure the structural strength. The stirring motor 17 is installed below this extension section.

[0028] It also includes a tensioner 12 for tensioning the transmission belt 13. In this embodiment, as Figure 4 shown, the tensioner 12 includes a base. A threaded rod is installed on the base. A wheel seat is installed at the front end of the threaded rod. A tensioning wheel is installed on the wheel seat, and the front part of the tensioning wheel abuts against the transmission belt 13. When it is necessary to adjust the tension degree of the transmission belt 13, rotate the threaded rod to shift the wheel seat and the tensioning wheel forward or backward.

[0029] The feed pipe 15 is installed and fixed on the top support frame 6. The inner end of the feed pipe 15 bends downward to enter the inside of the homogenizing tank 4. The outer end of the feed pipe 15 bends downward and a feed valve 16 is installed.

[0030] Please refer to Figure 2 and Figure 3 to see that

[0031] The bottom stirrer 3 of the tank includes a base 3-1 fixedly connected to the middle of the bottom wall of the homogenizing tank 4, that is, the bottom wall of the conical bottom. Above the base 3-1, a rotating seat 3-5 is installed through a gland 3-2, and a gear ring 3-8 is installed at the bottom of the rotating seat 3-5. It also includes a driving gear 3-4 meshing and driving with the gear ring 3-8. The driving gear 3-4 is driven by a driving motor 3-3 installed at the bottom of the base 3-1. A plurality of helical blades 3-6 are installed on the rotating seat 3-5 at equal angular intervals in the circumferential direction.

[0032] Both the driving gear 3-4 and the gear ring 3-8 are located below the gland 3-2. An axial hole is provided on the gland 3-2, and the root of the rotating seat 3-5 has a base ring adapted to the axial hole. The gear ring 3-8 is installed and fixed at the bottom of the base ring, so that the rotating seat 3-5 and its attached components will not come out upwards, but can only rotate under the action of the driving gear 3-4.

[0033] A support 3-7 is installed in the middle of the base 3-1, and the upper end of the support 3-7 extends into the inside of the rotating seat 3-5. An axial hole is provided on the side wall of the rotating seat 3-5, and a transmission shaft 3-10 is installed in the axial hole. The inner end of the helical blade 3-6 is fixedly connected to the outer end of the transmission shaft 3-10, and the inner end of the transmission shaft 3-10 and the upper end of the support 3-7 are connected by a bevel gear set 3-9 in transmission, that is, the bevel gear provided at the upper end of the support 3-7 is simultaneously in transmission connection with the bevel gears provided at the inner ends of the respective transmission shafts 3-10.

[0034] Therefore, each helical blade 3-6 of the bottom stirrer 3 of the tank not only has a revolution effect (rotating around the center line of the rotating seat 3-5), but also has a rotation effect (rotating around the center line of the transmission shaft 3-10). During the revolution process, each helical blade 3-6 exerts a circumferential stirring action on the collagen fiber slurry at the bottom of the tank. At the same time, during the rotation process, each helical blade 3-6 also exerts a radial pushing and stirring action on the collagen fiber slurry at the bottom of the tank, so that the regular laminar flow formed in the homogenizing tank 4 can be destroyed, and the efficiency and effect of homogenizing and stirring can be improved.

[0035] An annular flushing assembly 7 for flushing the inner wall of the homogenizing tank 4 is installed inside the open top of the homogenizing tank 4. The flushing assembly 7 has two functions: one function is to flush the inner wall of the tank after the collagen fiber slurry in the tank is discharged through the discharge pipe 2, so as to promote the shedding of the collagen fibers hanging on the inner wall of the homogenizing tank 4; the other function is to thoroughly flush and clean the inside of the homogenizing tank 4 after a certain period of use.

[0036] In this embodiment, the flushing assembly 7 includes an annular water distribution pipe installed and fixed at the bottom of the tank top bracket 8. A plurality of nozzles with jet directions facing outward and downward, that is, facing the inner wall of the tank, are installed on the annular water distribution pipe. The flushing assembly further includes a liquid inlet connector 9. The liquid inlet connector 9 includes a base fixedly connected to the tank top bracket 8 and a water inlet joint installed on the base. The outer end of the water inlet joint is connected to a water source through a pipeline, and the inner end is connected to the annular water distribution pipe through a pipeline.

[0037] Operation mode:

[0038] Inject the original bone collagen fiber slurry into the interior of the homogenizing tank 4 via the feed pipe 15. Start the stirring motor 17 and the driving motor 3-3. Then, the upper stirring impeller 18 and the lower stirring impeller 20 rotate uniformly inside the homogenizing tank 4, generating a strong stirring effect on the bone collagen fiber slurry. At the same time, the rotating seat 3-5 of the bottom tank stirrer 3 rotates uniformly. While the spiral blades 3-6 perform a revolution rotation, they also perform a self-rotation. This generates a circumferential stirring effect on the bone collagen fiber slurry at the bottom of the tank and a radial pushing and stirring effect at the same time.

[0039] After completing the homogenizing and stirring, open the discharge valve on the discharge pipe 2 to discharge the homogenized bone collagen fiber slurry in the tank and transfer it to the next processing equipment. Then, turn on the water supply of the flushing assembly 7. The flushing assembly 7 flushes the inner wall of the homogenizing tank 4 to promote the shedding of the bone collagen fiber adhering to the wall. This part of the cleaning liquid is not collected but discharged.

[0040] After using for a certain period of time, it is necessary to thoroughly clean the interior of the homogenizing tank 4. At this time, the water supply of the flushing assembly 7 can be turned on and cleaning water can be injected into the homogenizing tank 4 through the feed pipe 15. At the same time, start the stirring motor 17 and the driving motor 3-3 to keep the driving assembly and the bottom tank stirrer 3 in an operating state. The formed cleaning liquid is discharged through the discharge pipe 2. When necessary, the homogenizing tank 4 can be disassembled and deeply cleaned with a high-pressure water gun.
