Description
Technical Field
[0001] This utility model relates to the field of material preparation equipment technology, specifically to a stirring device for preparing highly biocompatible materials. Background Technology
[0002] In the preparation of highly biocompatible materials, such as medical polymer materials and bioceramics, it is necessary to thoroughly mix and stir various raw materials to ensure the uniformity and performance stability of the materials.
[0003] However, existing technologies still have many shortcomings in practical use. For example, existing stirring devices for preparing highly biocompatible materials have some deficiencies. On the one hand, the stirring paddle structure of traditional stirring devices is simple, often only providing a single stirring mode, such as simple radial stirring or axial stirring. For highly biocompatible materials, which require extremely high mixing uniformity, they cannot achieve effective stirring in all directions, which can easily lead to uneven mixing of materials and affect the performance of materials. At the same time, the cleaning problem during the stirring process cannot be ignored. The preparation of highly biocompatible materials requires the equipment to have a high degree of cleanliness to prevent impurities from being mixed in. However, the interior of existing stirring devices is not easy to clean, and material residues are easy to remain, causing contamination for the next stirring preparation. Utility Model Content
[0004] The purpose of this invention is to provide a stirring device for the preparation of highly biocompatible materials, which solves the problems of existing technologies that cannot effectively stir highly biocompatible materials in all directions and cannot clean the inside of the stirring tank, resulting in uneven mixing of materials that affects the performance of the materials and the easy presence of residual materials in the stirring tank that can cause contamination in the next stirring preparation.
[0005] This utility model provides the following technical solution: a stirring device for preparing highly biocompatible materials, including a support base, a shell fixedly installed at the top of the support base, a stirring tank fixedly installed inside the shell, a stirring mechanism for stirring materials inside the stirring tank, a heating tube for heating materials fitted on the outer wall of the stirring tank, and a cleaning mechanism for cleaning the stirring tank on the side of the support base away from the shell.
[0006] As a preferred embodiment of the above technical solution, a top cover is fixedly installed on the top of the shell and the top of the mixing tank. A feed inlet is provided on one side of the top of the top cover. The bottom of the shell and the mixing tank are installed through the support base. A discharge valve is installed at the bottom of the support base through a hinge. The top of the discharge valve is embedded in the interior of the mixing tank.
[0007] With the above technical solution, the material is fed into the mixing tank from the feed inlet. When the mixing of the material inside the mixing tank is completed, the discharge valve is opened to discharge the material that has been mixed inside the mixing tank.
[0008] As a preferred embodiment of the above technical solution, the stirring mechanism includes a stirring motor, which is fixedly installed on the top of the top cover. The output end of the stirring motor is fixedly connected to a rotating rod via a shaft. The bottom end of the rotating rod is fixedly connected to a first stirring paddle. The first stirring paddle has equidistant turbulence holes inside. A connecting plate is fitted on the surface of the rotating rod near the upper side of the first stirring paddle. Both ends of the connecting plate are fixedly connected to second stirring rods. The first stirring paddle and the second stirring rods are both located inside the stirring tank.
[0009] Through the above technical solution, the stirring motor is started to drive the rotating rod to rotate. The rotating rod drives the first stirring paddle to rotate inside the mixing tank. At the same time as the first stirring paddle rotates, the rotating rod drives two sets of second stirring rods to rotate inside the mixing tank through the connecting plate. The rotating first stirring paddle, together with the two sets of rotating second stirring rods, stirs the material inside the mixing tank. When the first stirring paddle stirs the material, the turbulence holes on the first stirring paddle cause the material to flow irregularly, which facilitates better mixing of the material while stirring, and realizes the function of fully stirring highly biocompatible materials.
[0010] As a preferred embodiment of the above technical solution, the input end of the heating tube is connected to a control valve via a pipe, and a suction pump is fixedly installed on one side of the outer wall of the housing via a mounting plate. The input end of the suction pump is connected to the output end of the heating tube via a pipe.
[0011] The above technical solution allows water from the circulating water tank to flow into the heating tube by opening the control valve. The heating tube is then activated to heat the water, and the heat from the hot water is transferred into the mixing tank through the outer wall of the mixing tank, thereby heating the material inside the mixing tank.
[0012] As a preferred embodiment of the above technical solution, a circulating water tank is fixedly installed on the side of the support base away from the shell. One side of the outer wall of the circulating water tank is connected to the input end of the control valve through a pipe. The upper side of the circulating water tank near the control valve is connected to the output end of the suction pump through a pipe. A water pump is fixedly installed on the top of the circulating water tank through a mounting plate. The output end of the water pump extends into the interior of the circulating water tank through a pipe.
[0013] With the above technical solution, when the temperature inside the mixing tank reaches a suitable temperature, the heating tube is turned off to stop heating the water. Then, the hot water inside the heating tube is drawn into the circulating water tank by starting the suction pump, thereby achieving the function of heating the materials and making the materials inside the mixing tank mix better.
[0014] As a preferred embodiment of the above technical solution, the cleaning mechanism includes a support rod, the bottom end of which is fixedly installed on the top end of a support base, a connecting rod fixedly connected to the top end of the support rod, a rotating shaft fitted onto the surface of the connecting rod, locking holes on both sides of the inside of the connecting rod, insertion holes on both sides of the inside of the rotating shaft, and pins inserted into the locking holes and insertion holes.
[0015] With the above technical solution, the staff can pull the pin out of the same set of lock holes and the same set of insertion holes to release the lock between the connecting rod and the shaft. The unlocked shaft can then be manually rotated on the surface of the connecting rod by the staff.
[0016] As a preferred embodiment of the above technical solution, an installation rod is fixedly connected to the outer wall of the rotating shaft near the feed inlet. A flexible hose is installed on one side of the surface of the installation rod through a clamp. The output end of the flexible hose is connected to a nozzle through a pipe. The input end of the installation rod is connected to the output end of the water pump through a pipe.
[0017] Through the above technical solution, the rotating shaft drives the mounting rod to rotate, and the rotating mounting rod drives the hose and nozzle to rotate, so that the nozzle can rotate to the top of the feed inlet. When the nozzle is completely above the feed inlet, the pin is re-inserted into another set of insertion holes and another set of locking holes to fix the rotating shaft and mounting rod. Then, the water pump is started to draw water from the circulating water tank into the hose. The nozzle then sprays the water from the hose into the mixing tank through the feed inlet. At the same time, the stirring motor is started to drive the first stirring blade and the second stirring rod to continuously stir the water and cleaning liquid inside the mixing tank. The mixed water and cleaning liquid, together with the continuous stirring of the first stirring blade and the second stirring rod, clean the inside of the mixing tank. When the cleaning of the mixing tank is completed, the discharge valve is opened to allow the water inside the mixing tank to be discharged.
[0018] Compared with the prior art, the beneficial effects of this utility model are: This invention allows materials to be fed into the mixing tank through the inlet. The mixing mechanism is then activated to stir and mix the materials inside the tank, achieving comprehensive and effective mixing of highly biocompatible materials. Workers inject cleaning solution into the mixing tank through the inlet, then move the cleaning mechanism above the inlet to spray water into the tank. Simultaneously, the mixing mechanism is activated to mix the water and cleaning solution inside the tank. The combined effect of the mixed water and cleaning solution, along with the continuous stirring of the mixing mechanism, cleans the inside of the tank, thus achieving the function of cleaning the tank interior. This avoids the problem of uneven material mixing affecting material performance and solves the problem of residual materials in the mixing tank causing contamination in subsequent mixing processes.

[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] like Figures 1-6As shown, this utility model provides a technical solution: a stirring device for preparing highly biocompatible materials, including a support base 1, a shell 2 fixedly installed on the top of the support base 1, a top cover 201 fixedly installed on the top of the shell 2 and the top of the stirring tank 3, a feed inlet 202 opened on one side of the top of the top of the top cover 201, the bottom of the shell 2 and the stirring tank 3 being installed through the support base 1, and a discharge valve 203 being installed on the bottom of the support base 1 through a hinge, the top of the discharge valve 203 being embedded in the interior of the stirring tank 3, and the discharge valve 203 is opened to discharge materials. Valve 203 facilitates the discharge of materials that have been mixed inside the mixing tank 3. The mixing tank 3 is fixedly installed inside the shell 2. The mixing tank 3 is equipped with a mixing mechanism 4 for mixing materials. The mixing mechanism 4 includes a mixing motor 401, which is fixedly installed on the top of the top cover 201. The output end of the mixing motor 401 is fixedly connected to a rotating rod 402 via a shaft. The bottom end of the rotating rod 402 is fixedly connected to a first mixing paddle 403. The first mixing paddle 403 has equidistant turbulence holes 404 inside. The rotating rod 40... A connecting plate 405 is fitted onto the upper side of the surface of the 2nd part near the first stirring paddle 403. A second stirring rod 406 is fixedly connected to both ends of the connecting plate 405. Both the first stirring paddle 403 and the second stirring rod 406 are located inside the mixing tank 3. Material is fed into the mixing tank 3 through the feed inlet 202. Then, the stirring motor 401 is started, driving the rotating rod 402 to rotate. The rotating rod 402 drives the first stirring paddle 403 to rotate inside the mixing tank 3. The first stirring paddle 403, driven by the rotating rod 402, rotates the first stirring rod 406. While the paddle 403 rotates, the rotating rod 402 drives two sets of second stirring rods 406 to rotate inside the mixing tank 3 via the connecting plate 405. The rotating first stirring paddle 403, in conjunction with the two sets of rotating second stirring rods 406, stirs the material inside the mixing tank 3. When the first stirring paddle 403 stirs the material, the turbulence holes 404 on the first stirring paddle 403 cause the material to flow irregularly, which facilitates better mixing of the material during stirring and achieves the function of fully stirring highly biocompatible materials. As one implementation method in this embodiment, such as Figure 1 , Figure 2 and Figure 4As shown, the outer wall of the mixing tank 3 is fitted with a heating pipe 5 for heating the material. The input end of the heating pipe 5 is connected to a control valve 501 via a pipe. A suction pump 502 is fixedly installed on one side of the outer wall of the shell 2 via a mounting plate. The input end of the suction pump 502 is connected to the output end of the heating pipe 5 via a pipe. A circulating water tank 6 is fixedly installed on the side of the support base away from the shell 2. One side of the outer wall of the circulating water tank 6 is connected to the input end of the control valve 501 via a pipe. The upper side of the circulating water tank 6 near the control valve 501 is connected to the output end of the suction pump 502 via a pipe. A water pump 6 is fixedly installed on the top of the circulating water tank 6 via a mounting plate. 01. The output end of the water pump 601 extends into the interior of the circulating water tank 6 through a pipe. By opening the control valve 501, water from the circulating water tank 6 flows into the heating pipe 5. Then, the heating pipe 5 is activated to heat the water. The heat from the hot water is introduced into the interior of the mixing tank 3 through the outer wall of the mixing tank 3, thereby heating the materials inside the mixing tank 3. When the temperature inside the mixing tank 3 reaches a suitable temperature, the heating pipe 5 is closed to stop heating the water. Then, the suction pump 502 is activated to draw the hot water from the heating pipe 5 into the circulating water tank 6, thus achieving the function of heating the materials and making the materials inside the mixing tank 3 mix better.
[0023] As one implementation method in this embodiment, such as Figure 1 , Figure 5 and Figure 6As shown, a cleaning mechanism 7 for cleaning the mixing tank 3 is provided on the side of the support base 1 away from the shell 2. The cleaning mechanism 7 includes a support rod 701, the bottom end of which is fixedly installed on the top end of the support base 1. A connecting rod 702 is fixedly connected to the top end of the support rod 701. A rotating shaft 703 is fitted onto the surface of the connecting rod 702. Locking holes 704 are provided on both sides inside the connecting rod 702. Insertion holes 705 are provided on both sides inside the rotating shaft 703. Pins 706 are inserted into the locking holes 704 and the insertion holes 705. The outer wall of the rotating shaft 703 is close to the feed inlet 202. A mounting rod 707 is fixedly connected to one side of the connecting rod 707. A hose 708 is installed on one side of the surface of the mounting rod 707 via a clamp. The output end of the hose 708 is connected to a nozzle 709 via a pipe. The input end of the mounting rod 707 is connected to the output end of the water pump 601 via a pipe. The cleaning fluid is introduced into the mixing tank 3 through the inlet 202. Then, the operator pulls out the pin 706 from the inside of one set of locking holes 704 and one set of insertion holes 705, which facilitates the release of the lock between the connecting rod 702 and the rotating shaft 703. The unlocked rotating shaft 703 is then easily accessible to the operator. The operator manually rotates the shaft 703 on the surface of the connecting rod 702. The rotating shaft 703 drives the mounting rod 707 to rotate, which in turn drives the hose 708 and the nozzle 709 to rotate, allowing the nozzle 709 to rotate above the feed inlet 202. When the nozzle 709 is completely above the feed inlet 202, the pin 706 is reinserted into another set of insertion holes 705 and another set of locking holes 704 to secure the shaft 703 and the mounting rod 707. Then, the water pump 601 is started to draw water from the circulating water tank 6 to the hose 708. Inside the 08, the water inside the hose 708 is sprayed into the mixing tank 3 through the feed inlet 202 by the nozzle 709. At the same time, the stirring motor 401 is started to drive the first stirring paddle 403 and the second stirring rod 406 to continuously stir the water and cleaning liquid inside the mixing tank 3. The mixed water and cleaning liquid, together with the continuous stirring of the first stirring paddle 403 and the second stirring rod 406, clean the inside of the mixing tank 3. When the cleaning of the inside of the mixing tank 3 is completed, the discharge valve 203 is opened to allow the water inside the mixing tank 3 to be discharged, thus realizing the function of cleaning the inside of the mixing tank 3.
[0024] Working principle: When it is necessary to stir highly biocompatible materials, the material is first fed into the mixing tank 3 through the feed inlet 202. Then, the stirring motor 401 is started to drive the rotating rod 402 to rotate. The rotating rod 402 drives the first stirring paddle 403 to rotate inside the mixing tank 3. While the first stirring paddle 403 is rotating, the rotating rod 402 drives two sets of second stirring rods 406 to rotate inside the mixing tank 3 through the connecting plate 405. The rotating first stirring paddle 403, together with the two sets of rotating second stirring rods 406, stirs the material inside the mixing tank 3. When the first stirring paddle 403 stirs the material, the turbulence holes 404 on the first stirring paddle 403 cause the material to flow irregularly, which facilitates better mixing of the material while stirring, and realizes the function of fully stirring highly biocompatible materials. The preparation of highly biocompatible materials sometimes requires reaction and mixing under specific temperature conditions. When the temperature of the material inside the mixing tank 3 is low, the control valve 501 is opened to allow water from the circulating water tank 6 to flow into the heating tube 5. Then, the heating tube 5 is activated to heat the water. The heat from the hot water is introduced into the mixing tank 3 through the outer wall of the mixing tank 3, thereby heating the material inside the mixing tank 3. When the temperature inside the mixing tank 3 reaches a suitable temperature, the heating tube 5 is closed to stop heating the water. Then, the suction pump 502 is activated to draw the hot water from the heating tube 5 into the circulating water tank 6, thus achieving the function of heating the material and making the material inside the mixing tank 3 mix better. When cleaning the interior of the mixing tank 3 is required, the operator first introduces the cleaning solution into the mixing tank 3 through the inlet 202. Then, the operator pulls the pin 706 out of the same set of locking holes 704 and one set of insertion holes 705, facilitating the release of the lock between the connecting rod 702 and the rotating shaft 703. The unlocked rotating shaft 703 allows the operator to manually rotate it on the surface of the connecting rod 702. The rotating shaft 703 drives the mounting rod 707 to rotate, which in turn drives the hose 708 and the nozzle 709 to rotate, allowing the nozzle 709 to rotate above the inlet 202. When the nozzle 709 is fully above the inlet 202, the pin 706 is reinserted into the other set of insertion holes 705. 5. The interior of another set of locking holes 704 facilitates the fixing of the rotating shaft 703 and the mounting rod 707. Then, by starting the water pump 601, the water inside the circulating water tank 6 is drawn into the hose 708. Then, the water inside the hose 708 is sprayed into the mixing tank 3 through the feed port 202 by the nozzle 709. At the same time, the stirring motor 401 is started to drive the first stirring paddle 403 and the second stirring rod 406 to continuously stir the water and cleaning liquid inside the mixing tank 3. The mixed water and cleaning liquid, together with the continuous stirring of the first stirring paddle 403 and the second stirring rod 406, clean the interior of the mixing tank 3. When the interior of the mixing tank 3 is cleaned, the discharge valve 203 is opened to allow the water inside the mixing tank 3 to be discharged, thus realizing the function of cleaning the interior of the mixing tank 3.
