Description

Technical Field

[0001] This utility model relates to the field of distribution technology, and in particular to a nitrogen uniform distribution device. Background Technology

[0002] Nitrogen, as an inert gas, can protect medicines from chemical reactions such as oxidation, thereby maintaining their stability and efficacy. In the process of filling ampoules with nitrogen, fully automatic or semi-automatic ampoule drawing and sealing machines are usually required. These machines are usually equipped with nitrogen filling interfaces and can automatically fill ampoules with nitrogen.

[0003] However, existing equipment uses stainless steel pipes with gas nozzles installed on the vertical surface to fill ampoules with nitrogen. Due to the limitations of the tubular structure and diameter, the gas output and pressure of each nozzle vary greatly, which poses a potential risk to product quality. Furthermore, the shaking of the gas pipes can affect the sealing of the connectors. Utility Model Content

[0004] The purpose of this invention is to address the limitations of existing technologies, such as the tubular structure and diameter, which result in significant differences in the air output and pressure of each nozzle, potentially affecting product quality. Furthermore, the vibration of the air pipe can compromise the sealing of the connector. Therefore, this invention proposes a nitrogen uniform distribution device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nitrogen uniform distribution device includes a gas cylinder, an extension pipe connected to the bottom end of the gas cylinder, a flange for connection to equipment fixedly fitted to the bottom end of the extension pipe, the extension pipe being connected to the gas outlet of the equipment, and multiple connectors connected to the outer wall of the top of the gas cylinder, with gas pipes inserted into the connectors, the other end of the gas pipes being connected to the equipment for filling ampoules with gas.

[0007] Multiple connectors are evenly distributed in a ring on the outer wall of the air tank and are located at the same height;

[0008] A support assembly, mounted on the air tank, is used to support and limit the movement of multiple air tubes.

[0009] In one possible design, the support assembly includes a retaining ring fitted onto the outer wall of the air tank. Both ends of the retaining ring have bends. A screw passes through one side of one of the bends, and the other end of the screw is threadedly connected to the other bend. A support base is fixedly mounted on the top of the retaining ring. Two clamps for clamping the air tube are adjustablely mounted on the two support bases. A drive unit is provided on the support base for driving the two clamps to move relative to each other.

[0010] In one possible design, the drive component includes a mounting block fixed to one end of the support base, wherein a bidirectional screw is rotatably provided through the top of one of the mounting blocks, and both clamping plates are threaded onto the bidirectional screw.

[0011] In one possible design, a guide rod is fixedly provided through the top of another mounting block, and both clamping plates are slidably sleeved on the guide rod for guiding and limiting the two clamping plates.

[0012] In one possible design, the two clamping plates are provided with pressure grooves corresponding to the air pipes on their adjacent sides.

[0013] In one possible design, the air tube is provided with an expansion section, the expansion section contains a steel ball, one side of the steel ball has a through hole, and the pressure groove has a groove corresponding to the expansion section for limiting the air tube.

[0014] In one possible design, a clearance groove corresponding to the mounting block is provided on the top of the clamping plate below, for making way for the mounting block.

[0015] Beneficial effects:

[0016] In this utility model, the nitrogen uniform distribution device, by designing the structure of the gas tank and multiple connectors, enables nitrogen to flow out uniformly from the multiple connectors at the top of the gas tank and to each ampoule that needs to be filled through the gas pipe, ensuring that each ampoule can obtain an equal or nearly equal amount of nitrogen, thereby improving the uniformity and efficiency of nitrogen distribution.

[0017] In this utility model, the nitrogen uniform distribution device uses a support component design to stably support and limit the air tube, preventing the air tube from shaking or falling off during the inflation process. By adjusting the position of the clamp, it can adapt to air tubes of different diameters or lengths, increasing the applicability and flexibility of the device. At the same time, the design of the pressure groove and expansion part further enhances the stability of the air tube, preventing the air tube from sliding or falling off under the action of high-pressure nitrogen.

[0018] In this invention, the nitrogen uniform distribution device employs a bidirectional screw and guide rod design, making the adjustment of the clamping plates simpler and more convenient. Rotating the bidirectional screw allows for synchronous movement of the clamping plates, enabling rapid clamping or release of the gas tube. Furthermore, the recessed groove design facilitates easier installation and disassembly of the clamping plates, simplifying device maintenance and upkeep.

[0019] In this invention, the uniform distribution and efficient inflation of nitrogen are achieved by designing an air tank and multiple evenly distributed annular connectors. At the same time, the innovative support component uses adjustable clamps to provide stable support and limit the air tube, ensuring that the air tube is stable and does not fall off. Furthermore, the combination of a bidirectional screw and a guide rod makes operation simple and easy to adjust. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figures 1-4 A dispensing device includes: a gas cylinder 4, the bottom end of which is connected to an extension pipe 2 by welding or other fixing method. A flange 3 is fixedly fitted onto the bottom end of the extension pipe 2, which is used to connect to the gas outlet of the equipment to ensure that nitrogen can smoothly enter the gas cylinder 4. Multiple connectors 5 are evenly arranged on the top outer wall of the gas cylinder 4. These connectors 5 are all arranged in a ring at the same height, and a gas pipe 6 can be inserted into each connector 5. The other end of these gas pipes 6 is connected to the equipment.

[0028] To ensure the stable operation of the multiple air tubes 6, a support assembly was designed to support and limit their movement. This support assembly includes a fixing ring 7 fitted onto the outer wall of the air tank 4. Both ends of the fixing ring 7 have bends 9, which enhance its structural strength. A screw 10 passes through one side of one bend 9, and the other end of the screw 10 is threaded into the other bend 9, thus securing the fixing ring 7 stably to the air tank 4. Two support seats 11 are fixedly mounted on the top of the fixing ring 7. Two adjustable clamps 8 are mounted on these support seats 11 to clamp the air tubes 6, preventing any shaking that could affect the sealing connection between the air tubes 6 and the connector 5.

[0029] To adjust the clamping plates 8, a driving component is provided on the support base 11. This driving component includes a mounting block 12 fixed to one end of the support base 11, with a bidirectional screw 14 rotatably mounted through the top of the mounting block 12. Both ends of the bidirectional screw 14 are threaded, and the two threads rotate in opposite directions. Both clamping plates 8 are threaded onto the bidirectional screw 14. Therefore, when the bidirectional screw 14 rotates, the two clamping plates 8 move closer or further apart, thereby clamping or releasing the air tube 6.

[0030] In addition, to better secure the trachea 6, pressure grooves 16 corresponding to the trachea 6 are provided on the adjacent sides of the two clamps 8. When the clamps 8 clamp the trachea 6, the trachea 6 will be tightly pressed into the pressure grooves 16, thus ensuring that it will not loosen or fall off.

[0031] This application can be used to allocate the field, or it can be used in other fields applicable to this application.

[0032] Example 2

[0033] refer to Figures 1-4 An improvement on Example 1 is provided: a nitrogen uniform distribution device applied to the distribution field. To ensure the stability of the two clamping plates 8 during movement, a guide rod 13 is fixedly installed through the top of another mounting block 12, and both clamping plates 8 are slidably sleeved on the guide rod 13. In this way, the guide rod 13 can guide and limit the movement of the clamping plates 8, preventing them from shifting or shaking.

[0034] Furthermore, an expansion section 18 is provided on the trachea 6, in which a steel ball 19 is embedded. A through hole 20 is provided on one side of the steel ball 19. A groove 17 corresponding to the expansion section 18 is provided in the pressure groove 16. When the trachea 6 is clamped in the pressure groove 16 by the clamping plate 8, the expansion section 18 is pressed into the groove 17, and the steel ball 19 is secured to the side wall of the groove 17 through the through hole 20, thereby further increasing the stability of the trachea 6.

[0035] Finally, to allow room for the mounting block 12 and ensure a tight fit between the two clamping plates 8, a clearance groove 15 corresponding to the mounting block 12 is provided on the top of the lower clamping plate 8. This way, when installing or removing the clamping plate 8, interference with the mounting block 12 can be avoided through the clearance groove 15.

[0036] In this application, when in use, the flange 3 is installed on the air outlet end of the equipment with bolts, the fixing ring 7 is then put on the air tank 4 and positioned below multiple connectors 5. After adjusting to a suitable position, the two ends of the fixing ring 7 are tightened by turning the screw 10, and then the air pipe 6 is inserted into the corresponding connectors 5 in sequence.

[0037] Then, multiple air tubes 6 are placed in the corresponding pressure grooves 16 in sequence, and the expansion part 18 is located in the groove 17. Then, the double-sided screw 14 is rotated. The rotation of the double-sided screw 14 can drive the two clamping plates 8 to move closer to each other. During the process of moving closer, the air tubes 6 can be clamped, and the expansion part 18 is limited by the two grooves 17. Finally, the other end of the air tube 6 is installed on the equipment. At this time, the air tube 6 will not affect the connection between the air tube 6 and the connector 5 during the process of shaking at the exhaust end of the air tube 6.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
