DETAILED DESCRIPTION

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0023] The principle of copper powder water atomization processing mainly involves contacting molten copper with water through spraying or atomization, thereby rapidly cooling and solidifying to form copper powder. The specific process is as follows: first, heat the copper metal to its melting point, usually above 1084℃, so that it completely melts into a liquid state. The molten copper is sprayed out through a nozzle at a certain flow rate, forming a stream or small droplets. In this process, the molten copper stream interacts with the high-pressure water stream. When the molten copper comes into contact with water, the water rapidly absorbs its heat, causing the molten copper to instantaneously cool and solidify, forming fine copper particles. This process is rapid to ensure that the copper powder does not re-melt. During atomization, due to the impact force and evaporation of water, many small particles are produced. After cooling, these particles exhibit different shapes and sizes, usually spherical or spherical-like. Finally, the solidified copper powder is collected and may undergo post-processing steps such as screening, washing, etc. to obtain copper powder of specific quality.

[0024] Based on the technical defects that the angle of the spray head 607 cannot be adjusted in the prior art, please refer to Figures 1-5 The metal copper powder atomization processing device provided by the present application can simultaneously control the movement of multiple spray heads 607 under the action of the synchronous driving assembly 603, so that the angle of the multiple spray heads 607 can be adjusted. In the face of different molten metal drop speeds and temperatures, the angle can be adjusted at any time to improve the atomization effect, thereby ensuring the uniformity of the copper powder processing particles. The device comprises a machine body 1, a melting furnace 2 is installed in the machine body 1, a discharge pipe 3 is connected to the bottom of the melting furnace 2, a material control valve 4 is installed on the discharge pipe 3, an atomization cover 5 is fixedly arranged at the bottom of the discharge pipe 3, a spraying mechanism 6 is fixedly arranged on the outer side of the discharge pipe 3, and the spraying mechanism 6 is connected to the outer side of the atomization cover 5. The copper material is placed in the melting furnace 2, the copper material is melted into a liquid state by the melting furnace 2, then the copper liquid is made to fall in the form of droplets by the material control valve 4, further, since the temperature of the copper liquid is high, the material control valve 4 can be made of high-temperature resistant material to ensure its normal use under high temperature, then high-pressure water is sprayed onto the falling copper liquid by the spraying mechanism 6, and water mist containing copper powder is formed after the copper liquid is contacted with the water.

[0025] Further, to ensure that the high-pressure water can produce a downward direction of splash in the atomization cover 5, the atomization cover 5 is preferably a horn-shaped structure.

[0026] To solve the angle adjustment problem of the spray head 607, please refer toFigure 3 and Figure 4 The spraying mechanism 6 includes multiple fixed columns 601 fixed to the bottom of the furnace 2. A fixed ring 602 is fixed to the bottom of each fixed column 601. A synchronous drive assembly 603 is fixed to the bottom of the fixed ring 602. At least three gears 604 are located below the synchronous drive assembly 603 and mesh with it. The gears 604 are rotatably connected to the bottom of the fixed ring 602 via a fixed plate 609. A swing arm 605 is fixed to the side wall of the gear 604. One end of the swing arm 605 is connected to a connecting fork 606. The nozzles 607 are hinged together and rotatably connected to the through holes on the side wall of the atomizing cover 5 via the rotating shaft 608. Under the action of the synchronous drive assembly 603, the angles of multiple nozzles 607 can be adjusted simultaneously, which has the advantage of convenient adjustment. During adjustment, the synchronous drive assembly 603 drives the swing arm 605 to rotate through the meshing action with the gear 604. The swing arm 605 drives the nozzles 607 to rotate under the hinge action of the connecting fork 606, so as to achieve the purpose of adjusting the angle of the nozzles 607.

[0027] To resolve the issue of simultaneous angle adjustment of multiple 607 nozzles, please refer to... Figure 3 The synchronous drive assembly 603 includes multiple electric push rods 6031 mounted on the bottom of the fixed ring 602. A movable ring 6032 is fixed on the drive shaft of the electric push rod 6031. At least three toothed plates 6033 that mesh with the gear 604 are fixed on the bottom of the movable ring 6032. The electric push rods 6031 drive the movable ring 6032 to move up and down. The movable ring 6032 drives the toothed plates 6033 to move up and down. Under the meshing action of the toothed plates 6033 and the gear 604, the angle of the nozzle 607 can be adjusted.

[0028] To address the stability issue of the movable ring 6032 during its lifting motion, a sliding groove is provided on the outer wall of the movable ring 6032, which is slidably connected to the side wall of the fixed column 601. The fixed column 601 limits the movement of the movable ring 6032 around its perimeter, thereby making the movable ring 6032 more stable during its lifting motion.

[0029] To facilitate the discharge of water containing copper powder, a collection hopper 7 is installed inside the body 1 below the atomizing hood 5. The bottom of the collection hopper 7 is connected to a discharge pipe 8 extending to the outside of the body 1. The collection hopper 7 collects the water and discharges it outward through the discharge pipe 8.

[0030] To maintain the internal condition of the furnace 2, a cover 9 is installed on the top of the machine body 1, which is located above the furnace 2.

[0031] To facilitate observation of water mist formation inside the machine body 1, a viewing window 10 is provided on the outer wall of the machine body 1; the viewing window 10 allows staff to easily observe the internal operation of the machine body 1.

[0032] As can be seen from the above embodiments: copper material is placed in furnace 2, and the copper material is melted into a liquid state by furnace 2. Then, the copper liquid is dripped down by the material control valve 4. At this time, under the action of nozzle 607, high-pressure water is sprayed out by nozzle 607. After contacting the copper liquid, water mist with copper powder is formed. Then, under the action of collection hopper 7, the copper powder and water are discharged together through discharge pipe 8. When it is necessary to adjust the angle of nozzle 607, the electric push rod 6031 is used to drive and drive the movable ring 6032 to move up and down. The movable ring 6032 drives the toothed plate 6033 to move up and down. The meshing action of toothed plate 6033 and gear 604 drives the swing arm 605 to rotate. The swing arm 605 drives the nozzle 607 to rotate under the hinge action of connecting fork 606, so as to achieve the purpose of adjusting the angle of nozzle 607.
