Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, specifically to a copper powder atomizing collector with anti-agglomeration function. Background Technology

[0002] With the rapid development of industries such as powder metallurgy, additive manufacturing (3D printing), electronic materials and precision manufacturing, especially in the application scenarios of high-purity, fine-grained metal powders, such as conductive slurries, metal injection molding, thermal spray coatings, etc., the industry has higher requirements for powder flowability, dispersibility and consistency. The problem of powder agglomeration caused by traditional collection equipment has become a bottleneck restricting production efficiency and product quality.

[0003] Most current metal powder atomizing collectors suffer from the following problems during use: after copper powder atomization, electrostatic adsorption and surface oxidation cause frequent powder agglomeration and clumping during collection, directly resulting in decreased powder flowability and uneven particle size distribution. Therefore, we propose a copper powder atomizing collector with anti-agglomeration function. Utility Model Content

[0004] The purpose of this invention is to provide a copper powder atomizing collector with anti-agglomeration function, which solves the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A copper powder atomizing collector with anti-agglomeration function includes a support frame. An atomizing chamber is fixedly installed on the top of the support frame. An inlet pipe is fixedly installed on the top of the atomizing chamber. A pneumatic diaphragm valve is provided at the bottom of the atomizing chamber. A powder collecting chamber is located at the bottom of the pneumatic diaphragm valve. A discharge port is fixedly installed at the bottom of the powder collecting chamber. An anti-agglomeration vibration device is provided inside the powder collecting chamber. A screen made of fine metal mesh is fixedly installed on the inner wall of the top of the powder collecting chamber. A motor is fixedly installed at the bottom of the powder collecting chamber. A rotating rod is rotatably installed at the output end of the motor. The rotating rod passes through and is rotatably installed at the bottom of the screen. A rotating groove is formed on the outer wall of the top of the rotating rod. A push plate is fixedly installed on the outer wall of the top of the rotating rod, and the push plate contacts the top of the screen.

[0007] Preferably, the vibration device includes a rotating shaft, a rotating block, a torsion spring, a connecting rod, a roller, and an inclined plate. The rotating shaft is fixedly installed on the inner wall of the rotating groove of the rotating rod, the rotating block is rotatably installed on the outer wall of the rotating shaft, the torsion spring is disposed between the rotating block and the inner wall of the rotating groove of the rotating rod, the connecting rod is fixedly installed on the end of the rotating block away from the rotating shaft, the roller is rotatably installed on the outer wall of the connecting rod, and the inclined plate is fixedly installed on the bottom of the screen near the inner wall of the powder collection bin.

[0008] Preferably, there are several rollers, and several rollers are in contact with the bottom of the screen. There are several inclined plates, and several inclined plates are located on the movement trajectory of the rollers at the top of the connecting rod. The inclination angle of several inclined plates is 45 degrees.

[0009] By employing the above technical solution, this utility model provides a copper powder atomizing collector with anti-agglomeration function. It possesses at least the following beneficial effects:

[0010] (1) By setting up a powder collection bin and a pusher plate at the top of the screen, the copper powder at the top of the screen is subjected to mechanical extrusion, which disperses the agglomerated copper powder during rotation, thereby achieving the effect of dispersing the agglomerated powder. The dispersed copper powder falls to the bottom of the powder collection bin and is then collected through the discharge port. During the sieving process, the pusher plate disperses the agglomerated powder and promotes the uniform dispersion of the powder, effectively solving the problem of powder agglomeration, improving sieving efficiency, and ensuring the uniformity and quality stability of powder collection.

[0011] (2) By setting up a vibration device and rollers, the top rollers quickly return to their original position after passing the inclined plate, and the rebound force of the torsion springs. This results in several rollers hitting the bottom surface of the screen, thereby causing the screen to vibrate at high frequency. This vibration can further effectively break up the powder agglomerates on the screen and prevent the screen holes from clogging. At the same time, the continuous mechanical vibration accelerates the separation and falling of powder particles, significantly improving the screening efficiency and enhancing the uniformity of powder dispersion, ensuring that the final collected powder has higher particle size consistency and process stability.

[0018] 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. Example

[0019] A copper powder atomizing collector with anti-agglomeration function, such as Figures 1-2 As shown, the device includes a support 1, an atomizing chamber 2 fixedly mounted on the top of the support 1, a feed pipe 3 fixedly mounted on the top of the atomizing chamber 2, a pneumatic diaphragm valve 4 at the bottom of the atomizing chamber 2, a powder collecting chamber 5 at the bottom of the pneumatic diaphragm valve 4, a discharge port 501 fixedly mounted on the bottom of the powder collecting chamber 5, a vibration device 6 for preventing agglomeration inside the powder collecting chamber 5, a screen 51 fixedly mounted on the inner wall of the top of the powder collecting chamber 5, the screen 51 being made of fine metal mesh, a motor 52 fixedly mounted on the bottom of the powder collecting chamber 5, a rotating rod 53 rotatably mounted on the output end of the motor 52, the rotating rod 53 passing through and rotatably mounted on the bottom of the screen 51, a rotating groove being opened on the outer wall of the top of the rotating rod 53, and a push plate 54 fixedly mounted on the outer wall of the top of the rotating rod 53, the push plate 54 contacting the top of the screen 51.

[0020] This utility model discloses a copper powder atomizing collector with anti-agglomeration function. In use, molten brass is added to the atomizing chamber 2 through the feed pipe 3 for atomization. After the brass is atomized into copper powder, the pneumatic diaphragm valve 4 is opened, and the copper powder falls through the valve to the top of the screen 51 in the powder collection chamber 5. When the copper powder is sieved and collected at the top of the screen 51, it agglomerates. At this time, the motor 52 is turned on, and the output of the motor 52 drives the rotating rod 53 to rotate. The rotating rod 53 drives the push plate 54 to move on the screen. The top of the screen 51 rotates, and the copper powder on the top of the screen 51 is subjected to mechanical extrusion, which disperses the agglomerated copper powder during the rotation, thereby achieving the effect of dispersing the agglomerated powder. The dispersed copper powder falls to the bottom of the powder collection bin 5 and is then collected through the feed port 501. During the screening process, the push plate 54 pushes the agglomerated powder apart and promotes the uniform dispersion of the powder, effectively solving the problem of powder agglomeration, improving screening efficiency, and ensuring the uniformity and quality stability of powder collection. Example

[0021] This embodiment, based on embodiment 1, specifically includes the following:

[0022] like Figures 3-4 As shown, the vibration device 6 includes a rotating shaft 61, a rotating block 62, a torsion spring 63, a connecting rod 64, a roller 65, and an inclined plate 66. The rotating shaft 61 is fixedly installed on the inner wall of the rotating groove of the rotating rod 53. The rotating block 62 is rotatably installed on the outer wall of the rotating shaft 61. The torsion spring 63 is disposed between the rotating block 62 and the inner wall of the rotating groove of the rotating rod 53. The connecting rod 64 is fixedly installed on the end of the rotating block 62 away from the rotating shaft 61. The roller 65 is rotatably installed on the outer wall of the connecting rod 64. The inclined plate 66 is fixedly installed on the bottom of the screen 51 near the inner wall of the powder collection bin 5.

[0023] There are several rollers 65, and several rollers 65 are in contact with the bottom of the screen 51. There are several inclined plates 66, and several inclined plates 66 are located on the movement trajectory of the rollers 65 at the top of the connecting rod 64, and the inclination angle of several inclined plates 66 is forty-five degrees.

[0024] In use, the copper powder atomizing collector of this utility model with anti-agglomeration function operates as follows: When the rotating rod 53 rotates, it drives the rotating shaft 61 to rotate, which in turn drives the rotating block 62 to rotate. The rotating block 62 then drives the connecting rod 64 and the torsion spring 63 to rotate. The connecting rod 64 drives the roller 65 to rotate. When the roller 65 at the top of the connecting rod 64 contacts the inclined plate 66 at a 45-degree angle, it causes the connecting rod 64 to rotate slightly downwards. The connecting rod 64 then drives the rotating block 62 to rotate slightly downwards. After passing the inclined plate 66, the rotating block 62 quickly rotates upwards to reset itself due to the rebound force of the torsion spring 63. The rotating block 62 then drives the connecting rod 64 to rotate upwards to reset itself. Several rollers 65 rotate upwards and reset rapidly. The rapid reset of the rollers 65 impacts the bottom surface of the screen 51. The inclined plates 66 allow the top rollers 65 to quickly reset after passing over the inclined plates 66 due to the rebound force of the torsion springs 63. This results in the rollers 65 repeatedly impacting the bottom surface of the screen 51, thereby causing high-frequency vibration of the screen 51. This vibration can further effectively break up powder agglomerates on the screen 51, preventing screen clogging. At the same time, the continuous mechanical vibration accelerates the separation and falling of powder particles, significantly improving screening efficiency and enhancing the uniformity of powder dispersion, ensuring that the finally collected powder has higher particle size consistency and process stability.
