Description

Technical Field

[0001] This utility model relates to the field of metal powder processing technology, and in particular to a metal powder degassing device. Background Technology

[0002] In the metal powder processing, in order to eliminate impurities such as air and moisture adsorbed by the metal powder during production, packaging or processing, reduce the impact of airlock effect on the process, and thus improve the purity of the metal powder, a metal powder degassing device is used. To address this, patent CN208374205U discloses a metal powder degassing and sealing device, comprising a powder tank, a transparent steel wire hose, a clamping valve, a vacuum degassing chamber, a coaxial valve, a casing, a clamp, and a vibration device. Powder in the powder tank enters the vacuum degassing chamber through the transparent steel wire hose and the clamping valve, where it is heated and degassed. The degassed powder is then evenly distributed into several powder supply pipes via a distributor, and subsequently into the casing, where it is compacted by the vibration device. Once the casing is full, the powder supply pipes above the casing are hydraulically clamped and sealed, completing the entire process. This invention offers excellent degassing performance, prevents powder from entering the vacuum system and damaging the vacuum pump unit, and is suitable for casings with multiple powder supply pipes. Furthermore, the amplitude and frequency are adjustable, resulting in excellent powder filling. Although the metal powder degassing and sealing device mentioned above will not allow powder to enter the vacuum system and damage the vacuum pump unit during use, its lack of protective measures makes it difficult to prevent powder from being sucked out of the casing, resulting in low applicability during use. Utility Model Content

[0003] The purpose of this invention is to provide a metal powder degassing device to address the shortcomings of existing metal powder degassing devices in terms of insufficient protective measures.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a metal powder degassing device, including a cladding container; Both ends of the sheath container are provided with connecting structures; The inner ends of the sheath container are provided with protective structures. The protective structures include small steel balls evenly distributed inside the sheath container. Support rings are fixed inside the sheath container at both ends of the small steel balls. A screen is provided at one end of each support ring. The protective structure has a disassembly mechanism on the outer wall of the container on both sides.

[0005] When using this device, the protective structure facilitates backflow prevention, thereby improving its applicability; the connecting structure facilitates fixing, thus improving its sealing; and the disassembly structure facilitates replacement and cleaning, thereby enhancing its ease of use.

[0006] Preferably, the connection structure includes a connecting pipe, a first clamp, a second clamp, a threaded post, a nut, and a sealing ring. The sealing ring is located at both ends of the enclosure container. A connecting pipe is provided at one end of each sealing ring. A first clamp is provided on one side of both the connecting pipe and the enclosure container, and a second clamp is provided on the other side of both the connecting pipe and the enclosure container. A threaded post is hinged to one side inside each of the first clamps, and a nut is threaded to the outer side of one end of each threaded post. The sealing ring and the connecting pipe are placed at one end of the enclosure container in sequence. The first clamp and the second clamp are then placed on the outside of the enclosure container and the connecting pipe. At this time, the threaded post is moved into the inside of the second clamp, and the nut is rotated simultaneously.

[0007] Preferably, the side of the first clamp away from the threaded post is hinged to the side of the second clamp, and one end of the nut abuts against the outer side of the second clamp. With the bottom end of the nut abutting against the outer side of the second clamp, the connecting pipe and the sheath container are fixed together. Under the action of the sealing ring, the gap between the connecting pipe and the sheath container is filled, ensuring a tight seal during use.

[0008] Preferably, the end of the screen away from the support ring is hinged with a handle, and the diameter of the small steel ball is larger than the diameter of the screen mesh. Airflow causes the small steel ball to float slightly, allowing gas to pass smoothly through the gap between the screen mesh and the small steel ball. Metal powder, due to insufficient airflow, is not moved and instead pushes the small steel ball towards the screen. Because the diameter of the small steel ball is larger than the diameter of the screen mesh, it accumulates densely on the screen surface, clogging the screen mesh and preventing further powder from being drawn into the vacuum pump, thus achieving an anti-backflow function.

[0009] Preferably, the disassembly structure includes a fixed frame, a movable ring, a movable rod, a threaded handle, a reset plate, a snap-fit ​​seat, and a reset spring. The fixed frame is fixed to the outer wall of the casing container on both sides of the screen. The movable rod runs through the interior of the fixed frame. A movable ring is fixed to one end of each movable rod, and a snap-fit ​​seat is fixed to the other end of each movable rod. A reset plate is fixed to the outer wall of the movable rod on one side of the snap-fit ​​seat. A reset spring is sleeved on the outer side of the movable rod on one side of the reset plate. A threaded handle is threadedly connected to one side of the top of the fixed frame.

[0010] Preferably, the screen on one side of the snap-fit ​​seat has a snap-fit ​​groove inside, and the snap-fit ​​seat and the screen form a snap-fit ​​structure through the snap-fit ​​groove. By moving the movable rod through the movable ring, the movable rod drives the snap-fit ​​seat to the outside of the snap-fit ​​groove. At this time, the threaded handle is rotated so that one side of the threaded handle abuts against one side of the reset plate, preventing the snap-fit ​​seat from springing back when replacing the screen.

[0011] Preferably, the reset plate and the snap-fit ​​seat form a telescopic structure via a reset spring. Rotating the threaded handle again separates it from the reset plate. Under the elastic force of the reset spring, the reset plate moves the snap-fit ​​seat into the snap-fit ​​groove, thereby fixing the screen and the casing container together.

[0012] The advantages of the metal powder degassing device provided by this utility model are as follows: With a protective structure, when the vacuum pump is started, the gas is drawn out from inside the enclosure. The airflow causes the small steel balls to float slightly. The gas can be smoothly discharged through the gap between the sieve holes and the small steel balls. The metal powder is not moved due to insufficient airflow. The powder pushes the small steel balls toward the sieve. Since the diameter of the small steel balls is larger than the diameter of the sieve holes, they will accumulate densely on the sieve surface, blocking the sieve holes, thereby preventing the powder from being sucked into the vacuum pump. This achieves the anti-backflow function, which improves the applicability of the metal powder degassing device. By setting up a connecting structure, the sealing ring and the connecting pipe are placed at one end of the enclosure container in sequence. The first clamp and the second clamp are then placed on the outside of the enclosure container and the connecting pipe. At this time, the threaded post is moved to the inside of the second clamp, and the nut is rotated so that the bottom end of the nut abuts against the outside of the second clamp. At this time, the connecting pipe and the enclosure container are fixed to each other. Under the action of the sealing ring, the gap between the connecting pipe and the enclosure container can be filled, ensuring the sealing performance during use. This realizes the function of easy fixation of the device, thereby improving the sealing performance of the metal powder degassing device during use. By incorporating a disassembly structure, the movable rod is moved via a movable ring, causing the movable rod to move the locking seat to the outside of the locking groove. At this point, the threaded handle is rotated so that one side of the threaded handle abuts against one side of the reset plate, preventing the locking seat from springing back when replacing the screen. The threaded handle is rotated again to separate the threaded handle from the reset plate. Under the elastic force of the reset spring, the reset plate moves the locking seat into the inside of the locking groove, thereby fixing the screen and the casing container together. This achieves the function of easy replacement and cleaning of the device, thus improving the convenience of using the metal powder degassing device. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6 The present invention provides a metal powder degassing device, comprising a sheathed container 1, with connecting structures 2 at both ends of the sheathed container 1. The connecting structures 2 include a connecting pipe 201, a first clamp 202, a second clamp 203, a threaded post 204, a nut 205, and a sealing ring 206. The sealing ring 206 is disposed at both ends of the sheathed container 1, with a connecting pipe 201 at one end of each sealing ring 206. A first clamp 202 is disposed on one side of the connecting pipe 201 and the sheathed container 1, and a second clamp 203 is disposed on the other side of the connecting pipe 201 and the sheathed container 1. A threaded post 204 is hinged to one side inside the first clamp 202, and a nut 205 is threadedly connected to the outer side of one end of the threaded post 204. The side of the first clamp 202 away from the threaded post 204 is hinged to one side of the second clamp 203, and one end of the nut 205 abuts against the outer side of the second clamp 203.

[0017] Reference Figure 5 and Figure 6As shown, the sealing ring 206 and the connecting pipe 201 are placed at one end of the housing container 1 in sequence. The first clamp 202 and the second clamp 203 are then fitted onto the outside of the housing container 1 and the connecting pipe 201. At this time, the nut 205 is rotated, and the first clamp 202 and the second clamp 203 are fixed to each other by the threaded post 204 and the nut 205, thereby fixing the connecting pipe 201 to the housing container 1. When the first clamp 202 and the second clamp 203 are tightened, the sealing ring 206 is compressed. Under the action of the sealing ring 206, the gap between the connecting pipe 201 and the housing container 1 can be filled, ensuring the sealing performance during use. In actual use, the end of the connecting pipe 201 away from the housing container 1 is connected to the suction port of the vacuum pump.

[0018] The inner ends of the casing container 1 are provided with protective structures 3. The protective structures 3 include small steel balls 301 evenly distributed inside the casing container 1. Support rings 303 are fixed inside the casing container 1 at both ends of the small steel balls 301. A screen 302 is provided at one end of the support ring 303. A handle is hinged to the end of the screen 302 away from the support ring 303. The diameter of the small steel balls 301 is larger than the diameter of the screen holes of the screen 302.

[0019] Reference Figure 2 and Figure 3 As shown, when the vacuum pump is started, the gas is drawn out from the inside of the encapsulated container 1. The airflow causes the small steel ball 301 to float slightly. The gas can be smoothly discharged through the gap between the sieve hole of the screen 302 and the small steel ball 301. The metal powder will not be moved due to insufficient airflow. The powder pushes the small steel ball 301 to gather towards the screen 302. Since the diameter of the small steel ball 301 is larger than the diameter of the sieve hole of the screen 302, it will be densely accumulated on the surface of the screen 302, blocking the sieve hole of the screen 302, thereby preventing the powder from being sucked into the vacuum pump, thus achieving the anti-backflow function.

[0020] The outer walls of the protective structure 3 and the two side enclosures 1 are each equipped with a disassembly structure 4. The disassembly structure 4 includes a fixed frame 401, a movable ring 402, a movable rod 403, a threaded handle 404, a reset plate 405, a locking seat 406, and a reset spring 407. The fixed frame 401 is fixed to the outer walls of the two side enclosures 1 of the screen 302. The movable rod 403 passes through the interior of the fixed frame 401. One end of the movable rod 403 is fixed with a movable ring 402, and the other end of the movable rod 403 is fixed with a locking seat. A reset plate 405 is fixed on the outer wall of the movable rod 403 on one side of the receiving seat 406. A reset spring 407 is sleeved on the outer side of the movable rod 403 on one side of the reset plate 405. A threaded handle 404 is threadedly connected to one side of the top of the fixed frame 401. A snap-fit ​​groove is opened inside the screen 302 on one side of the receiving seat 406. The receiving seat 406 and the screen 302 form a snap-fit ​​structure through the snap-fit ​​groove. The reset plate 405 and the receiving seat 406 form a telescopic structure through the reset spring 407.

[0021] Reference Figure 2 and Figure 3 As shown, the movable rod 403 is moved by the movable ring 402, causing the movable rod 403 to move the locking seat 406 to the outside of the locking groove. At this time, the threaded handle 404 is rotated so that one side of the threaded handle 404 abuts against one side of the reset plate 405, preventing the locking seat 406 from rebounding when the screen 302 is replaced. The screen 302 is moved by the handle, making it easy to pick up and put down the screen 302. The threaded handle 404 is rotated again to separate the threaded handle 404 from the reset plate 405. At this time, under the elastic force of the reset spring 407, the reset plate 405 will drive the locking seat 406 to move into the inside of the locking groove, thereby fixing the screen 302 and the packaging container 1 together.
