Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a device for preparing magnetic metal powder. Background Technology

[0002] Metal powder refers to groups of metal particles smaller than 1 mm in size. It includes single metal powders, alloy powders, and powders of certain refractory compounds with metallic properties. It is the main raw material for powder metallurgy. The production and application of metal powders have a long history. In ancient times, gold, silver, copper, bronze, and some of their oxide powders were used as coatings for coloring and decorating pottery, jewelry, and other utensils. In the early 20th century, American W.D. Coolidge used hydrogen reduction of tungsten oxide to produce tungsten powder for making tungsten wire, marking the beginning of modern metal powder production. Subsequently, chemical reduction methods were used to produce various powders such as copper, cobalt, nickel, iron, and tungsten carbide, promoting the development of early powder metallurgy products (oil-containing porous bearings, porous filters, hard alloys, etc.). At this time, the carbonyl method was also invented to produce iron and nickel powders. In the 1930s, eddy current grinding was first used to produce iron powder, and later, solid carbon reduction was used, which was very low-cost. In the early 1930s, molten metal atomization also emerged. This method was initially used to produce powders of low-melting-point metals such as tin, lead, and aluminum. By the early 1940s, it had evolved into the production of iron powder using high-pressure air atomization. In the 1950s, high-pressure water atomization began to be used to produce alloy steel and various alloy powders.

[0003] CN107262730A discloses a gas atomization preparation method and equipment for fine spherical metal powder. This method includes material melting, positive pressure driving of molten metal jet, gas atomization, cooling and powder collection, performance testing, sieving, and packaging. By reducing the outlet diameter of the guide nozzle, backfilling the melting chamber with inert gas to a certain positive pressure, designing the melting chamber in the gas atomization equipment as a pressure vessel, using a locking sealing device at the connection between the furnace cover and the furnace body, and designing the melting chamber and the atomization tank as mutually isolated cavities connected only by the guide nozzle, the yield of fine metal powder is effectively improved. Compared with existing gas atomization metal powder preparation technologies, the metal powder prepared by this method has a high yield, narrow particle size distribution, good sphericity, low oxygen content, and low atomizing gas consumption. Furthermore, the process equipment is simple, continuous, suitable for industrial production, and can be widely applied. However, the existing device still has shortcomings. In terms of cooling, the water will heat up if too much water is used to cool the metal powder, which will reduce the cooling effect. In addition, the existing device is not good at collecting the cooled magnetic metal powder. Therefore, we propose a magnetic metal powder preparation device to solve the above problems. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-4An embodiment of this utility model provides a magnetic metal powder preparation device, including a preparation tank body 1, a preparation mechanism 2 provided on the surface of the preparation tank body 1, the preparation mechanism 2 including a metal liquid pot 210, the metal liquid pot 210 being inserted into the top of the preparation tank body 1, an airflow nozzle 220 being installed inside the preparation tank body 1, a cooling collection tank 230 being provided at the bottom of the preparation tank body 1, a servo motor 240 being installed at the bottom of the cooling collection tank 230, a rotating bracket 250 being installed at the top of the servo motor 240, a first connecting rod 260 being fixed on the surface of the rotating bracket 250, and a second connecting rod 270 being provided on the surface of the first connecting rod 260;

[0023] Vent holes are provided at equal intervals at the top of the preparation tank body 1, and water filling holes are provided at the top of the preparation tank body 1. The vent holes facilitate the discharge of gas and avoid overpressure inside the device, while the water filling holes facilitate the addition of water to the cooling collection tank 230, thereby cooling the magnetic metal powder.

[0024] The surface of the preparation tank body 1 is provided with four sets of support rods, and the bottom end of the support rods is provided with rubber pads to support the device and enable the device to be placed stably.

[0025] The bottom of the liquid metal pot 210 is provided with airflow nozzles 220 on both sides. The airflow nozzles 220 are connected to the air pump to facilitate the blowing and dispersing of the falling liquid metal, thereby improving the preparation efficiency of magnetic metal powder.

[0026] The top of the rotating bracket 250 is provided with second connecting rods 270 at equal intervals. The second connecting rods 270 are located inside the cooling collection tank 230. While agitating the water to improve cooling efficiency, the second connecting rods 270 also increase the adsorption range of magnetic metal powder. The surface of the first connecting rod 260 is provided with threads, and the interior of the second connecting rod 270 is provided with threaded holes that are compatible with the first connecting rod 260. The first connecting rod 260 is inserted into the interior of the second connecting rod 270, which makes it easy to disassemble the second connecting rod 270 for collecting magnetic metal powder.

[0027] The second connecting rod 270 has a square structure and is made of magnetic material. The structure of the second connecting rod 270 allows its surface to attract more magnetic metal powder, and it is easier to scrape off. The material of the second connecting rod 270 allows it to attract magnetic metal powder.

[0028] Working principle: When the device is working, molten metal is poured from the molten metal pot 210 into the preparation tank body 1. After being blown away by the airflow nozzle 220, it falls into the cooling collection tank 230 for cooling. The cooling collection tank 230 contains cooling water. Under the action of the servo motor 240, the second connecting rod 270 rotates, accelerating the cooling of the water inside the cooling collection tank 230, thus speeding up the cooling of the metal powder and improving the cooling efficiency. The cooled metal powder will be adsorbed on the surface of the second connecting rod 270 under the action of the second connecting rod 270. The cooling collection tank 230 is threadedly connected to the molten metal pot 210. Rotating the cooling collection tank 230 can remove the cooling collection tank 230. Then, rotating the second connecting rod 270 can remove the second connecting rod 270 and the metal powder it has absorbed. The metal powder can then be scraped off the second connecting rod 270 for collection. The above is the complete working principle of this utility model.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
