Abstract
Description
Technical Field
[0001] This invention belongs to the field of collagen matrix processing technology, specifically relating to a device and method for rapid removal of volatile reagents applied to collagen matrices. Background Technology
[0002] Currently, biocompatible bone materials are used as dental filling materials due to their excellent biocompatibility, low likelihood of rejection, and ability to integrate well with surrounding tissues. Biocompatible bone materials also exhibit good bioactivity, promoting bone cell growth and regeneration, thus aiding in bone tissue repair and regeneration. Furthermore, their good stability and durability ensure long-term maintenance of the filling effect, reducing the risk of secondary surgery. However, because biocompatible bone materials contain various immunogenic substances, they must undergo a series of biochemical treatments to remove these substances before use to avoid immune rejection. Common treatment methods include defatting, decellularization, antigen removal, and virus removal, requiring the use of large amounts of biochemical reagents. Therefore, the thorough removal of residual chemical reagents is equally important.
[0003] Chinese patent document (CN202110089289.9) discloses a method for preparing oral collagen matrix materials using biological bone. In this method, during the degreasing process of the biological bone material, strips of bone raw material are poured into a mixed solution, stirred, soaked, and then removed. Subsequently, the strips of bone raw material need to be vacuum-dried to remove residual chloroform. Currently used vacuum drying equipment requires at least 10 hours of vacuum treatment, and the long chloroform volatilization time affects the preparation efficiency. During vacuum treatment, the strips of bone raw material are generally placed flat on a tray inside the vacuum drying equipment. This static placement not only affects the chloroform volatilization rate and prolongs the vacuum drying time, but also affects the uniformity of chloroform volatilization on the bone material, easily leading to residual gas on the bone material. Summary of the Invention
[0004] To address the aforementioned problems, this invention discloses a rapid removal device and method for volatile reagents, which solves the problems of slow removal rate of chloroform from bone raw materials and the easy presence of other residues in existing vacuum drying devices.
[0005] The specific technical solution is as follows: A rapid volatile reagent removal device includes a housing with a door at the front end, a vacuum chamber at the upper end, and an equipment compartment at the lower end. A rotating disk is horizontally mounted at the bottom of the vacuum chamber. The rotating disk has a hollow interior and several raw material placement cylinders for longitudinally placing strip-shaped bone materials are rotatably mounted on it. Each raw material placement cylinder has several placement openings on its sidewall, with openings at both the top and bottom. Several clamping devices for fixing the tops of the strip-shaped bone materials are circumferentially arranged on the upper sidewall of each raw material placement cylinder, with each clamping device located above one of the placement openings. The lower end of the raw material placement cylinder communicates with the inner cavity of the rotating disk. A movable tube is located at the center of the bottom of the rotating disk, penetrating the bottom of the vacuum chamber and entering the equipment compartment. The movable tube is rotatably connected to the bottom of the vacuum chamber via a sealed bearing. The movable tube is driven to rotate by a drive motor installed in the equipment compartment, causing the rotating disk to rotate horizontally in the vacuum chamber. The lower end of the movable tube is rotatably connected to a connecting pipe fixed in the equipment compartment. One side of the connecting pipe is connected to the air inlet of the vacuum pump in the equipment compartment through an air extraction pipe, so that the vacuum pump can perform vacuum treatment on the vacuum chamber. The air outlet of the vacuum pump is connected to a three-way solenoid valve through a pipeline. One end of the three-way solenoid valve is connected to the outside of the chamber through an exhaust pipe. The other end of the three-way solenoid valve is connected to a gas supply pipe. The gas supply pipe is connected to a circulation pipe installed in the interlayer of the side wall of the chamber. One end of the circulation pipe extends upward to the top of the vacuum chamber and has a return gas port at the top of the vacuum chamber corresponding to the position of the rotating disk. The lower end of the return gas port extends into the vacuum chamber, so that the vacuum chamber can achieve vacuum circulation degassing function under the action of the vacuum pump.
[0006] Furthermore, it also includes a gas replenishment device, which includes an inert gas cylinder installed in the equipment compartment. The outlet end of the inert gas cylinder is connected to a three-way solenoid valve two. One end of the three-way solenoid valve two is connected to the vacuum chamber through a gas replenishment pipe to replenish inert gas into the vacuum chamber. The other end of the three-way solenoid valve two is open to the atmosphere.
[0007] Furthermore, several of the raw material placement cylinders are evenly distributed circumferentially on the rotating disk. The lower end of each raw material placement cylinder is provided with a guide cavity. The lower end of the guide cavity is tapered and extends to the bottom opening of the raw material placement cylinder. A grid guide plate is provided in the guide cavity to avoid generating chaotic eddies when the vacuum pump is pumping air. A barrier net is provided at the upper opening of each raw material placement cylinder and at the upper end of the guide cavity.
[0008] Furthermore, the upper side wall of the raw material placement cylinder is provided with several arc-shaped clamping grooves along the circumference. The clamping grooves are all located at the upper end of the placement opening. Each clamping groove is provided with a clamping device, which includes a clamping block. One end of the clamping block is adapted to the size and shape of the clamping groove, and the other end of the clamping block extends to the outside of the clamping groove and is provided with a lever. A hinge joint is provided on one side of the clamping block, and a hinge groove for accommodating the hinge joint is provided on one side of the clamping groove. A hinge shaft is provided longitudinally on the hinge joint, and the hinge shaft is rotatably connected to the hinge groove. A torsion spring is sleeved on the hinge shaft, so that the clamping block presses and fixes the top of the strip bone material in the clamping groove under the action of the torsion spring.
[0009] Furthermore, the inner cavity of the rotating disk is provided with a through cavity communicating with the movable tube. Air passages are respectively opened around the through cavity in the inner cavity of the rotating disk. The top end of each air passage is open. A rotating seat is provided on the upper surface of the rotating disk at the opening position of each air passage. The raw material placement cylinder is rotatably mounted in the rotating seat through a sealed bearing, so that the lower opening of the raw material placement cylinder is connected to the top opening of the air passage.
[0010] Furthermore, the drive motor is mounted in the equipment compartment via a bracket. The output end of the drive motor is equipped with a drive wheel, and a driven wheel is mounted on the movable tube. The driven wheel and the drive wheel are connected by a transmission belt, so that the drive motor drives the movable tube and the rotating disk to rotate.
[0011] Furthermore, a cylindrical sleeve is fitted on the outer wall of the raw material placement cylinder. The sleeve is horizontally rotatably connected to the raw material placement cylinder, and the inner wall of the sleeve is fitted to the outer wall of the raw material placement cylinder. Several openings corresponding to the placement ports are opened circumferentially on the side wall of the sleeve. By rotating the sleeve, the sleeve can be used to close the placement ports on the side wall of the raw material placement cylinder.
[0012] A method for removing volatile reagents using a rapid removal device, comprising the following specific steps: Step 1: Open the box door, use the clamping device to clamp and fix the top of each strip of bone material on each raw material placement cylinder, and then rotate the sleeve to close the placement opening; Step 2: Close the chamber door, control the three-way solenoid valve to connect the suction pipe and the exhaust pipe, and then start the vacuum pump to evacuate the vacuum chamber. Step 3: After the vacuum chamber is evacuated, turn off the vacuum pump, control the three-way solenoid valve one to connect the suction pipe and the gas supply pipe, and at the same time open the three-way solenoid valve two to allow a small amount of inert gas from the inert gas bottle to enter the vacuum chamber, so that the vacuum chamber is in a rough vacuum state. Step 4: Restart the vacuum pump. The vacuum pump will extract the gas from the vacuum chamber to create a vacuum environment. The extracted gas will be reinjected into the vacuum chamber through circulation and extracted again. This cycle is repeated to achieve vacuum circulation degassing and improve the evaporation rate of chloroform. Step 5: After the chloroform is removed, turn off the vacuum pump and control the three-way solenoid valve to allow outside air to enter the vacuum chamber. After the air pressure inside and outside the vacuum chamber is balanced, open the chamber door, unscrew the sleeve, and remove the strip bone material from the raw material placement cylinder.
[0013] The beneficial effects of this invention are reflected in: In this invention, a vacuum pump is used to evacuate the vacuum chamber, and then a small amount of inert gas is injected into the vacuum chamber to form a rough vacuum state. Under the cyclic pumping action of the vacuum chamber, the strip-shaped bone raw material is degassed in a vacuum cycle. Compared with traditional degassed methods, it can remove the gas in the raw material more thoroughly, increase the evaporation rate of chloroform, reduce the vacuum drying time, save energy and materials, and reduce the impact on the environment.
[0014] In this invention, a clamping device holds and fixes strip-shaped bone materials on the raw material placement cylinder, causing the strip-shaped bone materials to hang downwards. The bottom opening of the raw material placement cylinder is connected to the air extraction pipe, while the top opening corresponds to the position of the return air pipe. Thus, during vacuum circulation degassing, an airflow from top to bottom can be formed inside the raw material placement cylinder, allowing the strip-shaped bone materials to swing with the airflow. This enables uniform processing of the raw materials, ensuring that each part is fully degassed and avoiding gas residue. Attached Figure Description

The upper end of the housing 1 has a vacuum chamber, and the lower end of the housing 1 has an equipment compartment 4. The front end of the housing 1 has a door 2 for sealing the vacuum chamber. An interlayer is provided between the vacuum chamber at the upper end of the housing 1 and the housing shell for pipeline arrangement. A rotating disk 5 is horizontally rotatable on the left and right sides of the bottom of the vacuum chamber. The rotating disk 5 has a hollow internal structure. Four raw material placement cylinders 6 for longitudinally placing strip-shaped bone materials are rotatably mounted on the rotating disk 5. The side walls of the raw material placement cylinders 6 have several placement openings 64. Both the upper and lower ends of the raw material placement cylinders 6 are open. Several clamping devices 66 for fixing the top ends of the strip-shaped bone materials are arranged circumferentially on the upper side wall of the raw material placement cylinders 6. The clamping devices 66 are all located above the placement openings 64, allowing the strip-shaped bone materials to enter the inner side of the raw material placement cylinders 6 through the placement openings 64. The lower end of the raw material placement cylinders 6 communicates with the inner cavity of the rotating disk 5.
[0028] Each rotating disk 5 has a movable tube 51 at its bottom center. The movable tube 51 passes through the bottom of the vacuum chamber and enters the equipment chamber 4. The movable tube 51 is rotatably connected to the bottom of the vacuum chamber through a sealed bearing. Both movable tubes 51 are driven to rotate by a drive motor 48 installed in the equipment chamber 4, causing the rotating disk 5 to rotate horizontally in the vacuum chamber. The lower ends of the two movable tubes 51 are rotatably connected to a connecting pipe 42 fixed in the equipment chamber 4. The connecting pipe 42 has a U-shaped structure, and its two ends are rotatably connected to the lower ends of the movable tubes 51 through sealed bearings. The center of one side of the connecting pipe 42 is connected to the air inlet of the vacuum pump 41 in the equipment chamber 4 through a suction pipe 43, so that the vacuum pump 41 can perform vacuuming treatment on the vacuum chamber. The outlet of the vacuum pump 41 is connected to a three-way solenoid valve 44 via a pipeline. One end of the three-way solenoid valve 44 is connected to the outside of the housing 1 via an exhaust pipe 441. The other end of the three-way solenoid valve 44 is connected to a gas supply pipe 442. The gas supply pipe 442 is connected to a circulation pipe 45 located in the interlayer of the side wall of the housing 1. One end of the circulation pipe 45 extends upward to the top of the vacuum chamber 3 and has a return gas port 451 at the top of the vacuum chamber 3 corresponding to the position of the rotating disk 5. The lower end of the return gas port 451 extends into the vacuum chamber 3, so that an airflow from top to bottom is formed in the raw material placement cylinder 6. The strip-shaped bone raw material can swing with the airflow. The vacuum chamber 3 achieves the vacuum circulation degassing function under the action of the vacuum pump 41.
[0029] This embodiment also includes a gas replenishment device, which includes an inert gas cylinder 46 disposed in the equipment compartment 4. The outlet end of the inert gas cylinder 46 is connected to a three-way solenoid valve 47. One end of the three-way solenoid valve 47 is connected to the vacuum chamber through a gas replenishment pipe 471 to replenish inert gas into the vacuum chamber. The other end of the three-way solenoid valve 47 is in communication with the atmosphere.
[0030] The rotating disk 5 has a through cavity 501 at its center, which is connected to the movable tube 51. Air passages 502 are respectively opened around the through cavity 501 in the inner cavity of the rotating disk 5. The top end of each air passage 502 is open. A rotating seat 52 is respectively provided on the upper surface of the rotating disk 5 at the opening position of each air passage 502. The raw material placement cylinder 6 is rotatably mounted in the rotating seat 52 through a sealed bearing, so that the lower opening of the raw material placement cylinder 6 is connected to the top opening of the air passage 502.
[0031] The raw material placement cylinders 6 are evenly distributed around the rotating disk 5. The lower end of the raw material placement cylinder 6 is provided with a guide cavity 61. The lower end of the guide cavity 61 is tapered and extends to the bottom opening of the raw material placement cylinder 6. The guide cavity 61 is provided with a grid guide plate 62 to avoid the generation of chaotic eddies when the vacuum pump 41 is pumping air. The upper opening of each raw material placement cylinder 6 and the upper end of the guide cavity 61 are provided with a barrier net 63 to prevent strip-shaped bone raw materials from falling into the guide cavity 61.
[0032] Several arc-shaped clamping grooves 65 are circumferentially formed on the upper side wall of the raw material placement cylinder 6. The clamping grooves 65 are all located at the upper end of the placement opening 64. Each clamping groove 65 is provided with a clamping device 66, which includes a clamping block 661. The front end of the clamping block 661 is arc-shaped and adapted to the size and shape of the clamping groove 65.

A hinge joint 663 is provided on one side of the clamping block 661, and a hinge is provided on one side of the clamping groove 65 for accommodating the hinge. The joint 663 has a hinge groove 651, and the hinge joint 663 is provided with a hinge shaft 664 in the longitudinal direction. The hinge shaft 664 is rotatably connected to the hinge groove 651, and a torsion spring 665 is sleeved on the hinge shaft 664. Under the action of the torsion spring 665, the clamping block 661 presses and fixes the top of the strip bone material in the clamping groove 65, so that each strip bone material is in a hanging state. After long-term soaking and washing treatment, the texture of the strip bone material has become flexible. Under the circulation pumping treatment of the vacuum pump 41, the bone material can swing with the airflow.
[0033] In this embodiment, the drive motor 48 is mounted in the equipment compartment 4 via a bracket. The output end of the drive motor 48 is provided with a drive wheel 481, and driven wheels 482 are mounted on the two movable tubes 51. The two driven wheels 482 and the drive wheel 481 are respectively connected by a transmission belt 483, so that the drive motor 48 drives the two movable tubes 51 and the two rotating disks 5 to rotate, thereby allowing the airflow to enter each raw material placement cylinder 6 evenly.
[0034] In another embodiment, to ensure a stable airflow through the raw material placement cylinder 6 from top to bottom, a cylindrical sleeve 67 may be fitted onto the outer wall of the raw material placement cylinder 6, such as... Figure 9As shown, the sleeve 67 is made of transparent material. The lower end of the inner wall of the sleeve 67 is horizontally rotatably connected to the outer wall of the raw material placement cylinder 6, and the inner wall of the sleeve 67 is fitted to the outer wall of the raw material placement cylinder 6. Several openings 671 corresponding to the placement ports 64 are opened circumferentially on the side wall of the sleeve 67. The upper end of the openings 671 extends to the top of the sleeve 67. By rotating the sleeve 67, the sleeve 67 can close the placement ports 64 on the side wall of the raw material placement cylinder 6. By closing the placement ports 64, the airflow can stably pass through the raw material placement cylinder 6 from top to bottom, reducing the occurrence of turbulence.
[0035] This embodiment also includes a PLC controller and a pressure sensor 301 installed in the vacuum chamber. The PLC controller is electrically connected to the vacuum pump 41, the drive motor 48, the pressure sensor 301, the three-way solenoid valve 44, and the three-way solenoid valve 47, respectively, so that the PLC controller can control the operation of each component. The PLC controller, the vacuum pump 41, the drive motor 48, the pressure sensor 301, the three-way solenoid valve 44, and the three-way solenoid valve 47 are all existing technologies.
[0036] This embodiment also provides a method for removing volatile reagents using a rapid removal device, the specific steps of which are as follows: Open the box door 2, and clamp and fix the top of each strip bone material on each raw material placement cylinder 6 using the clamping device 66. Then rotate the sleeve 67 to close the placement opening 64. By rotating the raw material placement cylinder 6 and the rotating disk 5, each strip bone material is fixed in the clamping groove 65.
[0037] Close the chamber door 2, control the three-way solenoid valve 44 through the PLC controller to connect the suction pipe 43 and the exhaust pipe 441, and then start the vacuum pump 41 through the PLC controller to perform vacuuming on the vacuum chamber 3.
[0038] After the vacuum chamber 3 is evacuated, the vacuum pump 41 is turned off. The PLC controller controls the three-way solenoid valve 44 to connect the suction pipe 43 with the gas supply pipe 442. At the same time, the PLC controller opens the three-way solenoid valve 47 to allow a small amount of inert gas from the inert gas bottle 46 to enter the vacuum chamber 3, so that the vacuum chamber 3 is in a rough vacuum state.
[0039] The vacuum pump 41 is restarted, and the vacuum pump 41 extracts the gas in the vacuum chamber 3 to form a vacuum environment. The extracted gas is then reinjected into the vacuum chamber through circulation and extracted again. This cycle is repeated to achieve vacuum circulation degassing, thereby increasing the evaporation rate of chloroform.
[0040] After the chloroform removal is complete, turn off the vacuum pump 41, and control the three-way solenoid valve 47 through the PLC controller to allow outside air to enter the vacuum chamber 3. After the air pressure inside and outside the vacuum chamber 3 is balanced, open the chamber door 2, unscrew the sleeve 67 and take the strip bone raw material from the raw material placement cylinder 6 to complete the chloroform gas removal process.

Step 2: Close the box door (2), control the three-way solenoid valve (44) to connect the suction pipe (43) and the exhaust pipe (441), and then start the vacuum pump (41) to evacuate the vacuum chamber (3); Step 3: After the vacuum chamber (3) is evacuated, turn off the vacuum pump (41), control the three-way solenoid valve one (44) to connect the suction pipe (43) and the gas supply pipe (442), and at the same time open the three-way solenoid valve two (47) to allow a small amount of inert gas in the inert gas bottle (46) to enter the vacuum chamber (3) and put the vacuum chamber (3) into a rough vacuum state. Then close the three-way solenoid valve two. Step 4: Restart the vacuum pump (41). The vacuum pump (41) extracts the gas in the vacuum chamber (3). The extracted gas is then re-injected into the vacuum chamber through circulation and extracted again. This cycle is repeated to achieve vacuum circulation degassing and improve the evaporation rate of chloroform. Step 5: After the chloroform is removed, turn off the vacuum pump (41), control the three-way solenoid valve 2 (47) to allow external air to enter the vacuum chamber (3), and after the air pressure inside and outside the vacuum chamber (3) is balanced, open the chamber door (2), unscrew the sleeve (67) and take the strip bone raw material from the raw material placement cylinder (6).
