Description

Technical Field

[0001] The invention belongs to the technical field of metal powder manufacturing devices, and in particular relates to a continuous metal powder manufacturing device and method. Background Art

[0002] Metal powder is a tiny particle or powdered substance made of metal or alloy through a specific process. This powder can be composed of one or more metal elements, such as iron, copper, aluminum, zinc, titanium, etc., or an alloy composed of these metals. There are many methods for its preparation, including mechanical crushing, physical and chemical methods and electrolysis. The physical and chemical methods include reduction, atomization and electrolysis.

[0003] The atomization method of metal powder is a method of preparing powder by using a fast-moving fluid (atomizing medium) to impact or otherwise break the metal or alloy liquid into fine droplets, and then condense it into solid powder. Its principle is mainly to use external forces such as high-speed airflow, water flow or ultrasound to break the molten metal or alloy liquid into tiny droplets, which solidify into powder after rapid cooling.

[0004] The water atomization method uses high-pressure water flow to impact molten metal liquid, breaking it into fine droplets and then quickly condensing it into powder. The powder particles prepared by the water atomization method are mostly irregular in shape and have a high oxygen content, but have good compressibility and are suitable for cold pressing. In addition, the water atomization method has the advantages of high economy and good environmental protection, but the equipment requirements are high and the process is relatively complex.

[0005] Metal powder manufacturing devices are equipment used to produce metal powders. These devices are widely used in industrial manufacturing, especially in the fields of aerospace, automobiles, electronics, medical equipment and military industry. They include water atomization powder making machines, metal powder granulators, vacuum gas atomization powder making equipment, electrode induction gas atomization powder making equipment and plasma rotating electrode powder making equipment. The water atomization powder making machine melts the metal raw materials in a furnace, and the melt is poured into a tundish placed on the top of the atomization chamber. The melt flows through the opening at the bottom of the tundish into the atomizer and is decomposed into molten droplets by high-pressure water jets. These droplets cool and solidify during falling and deposition, and finally form metal powder. It is suitable for the production of a variety of metal powders, such as gold, silver, copper, etc.

[0006] Publication number "CN111741826B" records that "a metal powder manufacturing device comprises: a molten metal supply portion for supplying molten metal; a cylindrical body comprising an upper portion arranged below the molten metal supply portion and a lower portion arranged below the upper portion; a fluid injection portion for injecting gas toward the molten metal; and a coolant outflow portion for causing the coolant to flow out along the inner circumferential surface of the upper portion. In such a metal powder manufacturing device, an angle formed by an axis line of the upper portion of the cylindrical body and a plumb line is greater than 0° and less than 20°, and an angle formed by an axis line of the lower portion of the cylindrical body and a plumb line is greater than 0° and less than 20°. In addition, the minimum inner diameter of the lower portion of the cylindrical body is greater than 15% and less than 85% of the inner diameter of the upper portion."

[0007] The above patent divides the molten metal by a fluid with a relatively small heat capacity, so that the oxidation of the metal can be suppressed during the powderization process. As a result, the molten metal can be divided while suppressing the oxidation and significant deformation of the droplets, so that the unintentional composition changes can be controlled to a lesser extent, and the metal powder that has fully achieved spherical shape can be manufactured. However, in the actual use of the atomization method metal powder manufacturing device, the high-pressure nozzle cannot adjust the injection angle, resulting in the inability to adapt to the optimal injection angle and height of the different metal molten injection when frequently changing different metals, resulting in a decrease in the manufacturing efficiency of different metal powders when switching between different metal atomization powder production. For this reason, we propose a continuous metal powder manufacturing device and method. Summary of the invention

[0022] A continuous metal powder manufacturing method comprises the following steps:

[0023] S1. Feeding:

[0024] The heated molten metal liquid is poured into the heating kettle, and the electric heater is powered on to heat and keep the heating kettle and the molten metal liquid in the heating kettle, so as to keep the metal in a molten state, so that the molten metal liquid can fall from the bottom of the heating kettle into the atomizing tank, thereby feeding the atomizing tank;

[0025] S2. Powder preparation:

[0026] When the molten metal falls, high-pressure water vapor enters the gas filling ring through two air inlet valves, is introduced into the sealed water vapor ring from the two extension pipes of the gas filling ring, and is introduced into the high-pressure nozzle along two guide tubes. The two high-pressure nozzles simultaneously spray high-pressure water vapor to the dripping molten metal, breaking the molten metal into tiny droplets to form atomized metal liquid, which is then quickly cooled into metal powder to achieve powder preparation of metal powder;

[0027] S3, height fine-tuning:

[0028] During the atomization preparation process, when different types of metals are frequently changed, multiple cylinders are powered on to start, and the output ends of the multiple cylinders are telescopically moved. The output ends of the multiple cylinders push and pull the lifting sleeves in the rotating drum to lift and lower, and then the lifting sleeve drives the two high-pressure nozzles to lift and lower, so that the high-pressure water vapor sprayed by the two high-pressure nozzles can be fine-tuned in height according to the type of metal, and the distance between the intersection of the two high-pressure nozzles and the bottom of the heating kettle is controlled to meet the needs of the asynchronous metal atomization falling height. By lifting and lowering the lifting sleeve, the height of the two high-pressure nozzles can be fine-tuned;

[0029] S4, Angle adjustment:

[0030] During the atomization preparation process, when the height fine-tuning cannot meet the metal atomization requirements, the two micromotors are powered on and started, and the output ends of the two micromotors drive the two screws to rotate. The two screws push the two sliders to move up and down in the two slide rails through the sliding cooperation with the two sliders. The two sliders push and pull the two connecting rods, and the two connecting rods push and pull the two eccentric blocks to deflect. The two eccentric blocks drive the two high-pressure nozzles to deflect through the hollow rotating shaft, so that the two high-pressure nozzles can deflect by 45 degrees to minus 45 degrees. The two high-pressure nozzles are deflected to the atomization drop height required by the corresponding molten metal liquid. When the two high-pressure nozzles are deflected to the angle required by the molten metal liquid, the high-pressure water vapor sprayed by the two high-pressure nozzles is the atomization drop height required by the corresponding molten metal liquid, and the two micromotors are powered off and stopped, and the deflection angles of the two high-pressure nozzles are locked by the self-locking of the two heating kettles and the two sliders to achieve angle adjustment of the two high-pressure nozzles;

[0031] S5. Real-time monitoring:

[0032] During the atomization preparation process, the camera takes real-time photos of the intersection of high-pressure water vapor sprayed by two high-pressure nozzles and the falling line of the molten metal liquid, providing image and data reference for powder preparation and achieving real-time monitoring;

[0033] S6, Rotation Cleaning:

[0034] When the preparation of single metal powder is completed, the two high-pressure nozzles are deflected to negative 45 degrees, and the electric push rod is powered on first. The output end of the electric push rod contracts and pulls the pawl away from the ratchet to release the engagement between the ratchet and the pawl. Then the motor is powered on and the output end of the motor drives the driven gear to rotate. The driven gear drives the drum to rotate through the engagement with the driving gear. The drum drives the lifting sleeve to rotate, and the lifting sleeve drives the two high-pressure nozzles to rotate. The two high-pressure nozzles use rotation to spray high-pressure water vapor on the inner wall of the atomization tank to fully clean the metal powder attached to the inner wall of the atomization tank. The metal powder is flushed out with the water flow. After the metal powder in the atomization tank is cleaned, the motor is powered off and stopped. The output end of the electric push rod extends to push the pawl to engage with the ratchet to lock the rotation of the drum. By rotating the two high-pressure nozzles, the metal powder in the atomization tank is rotated and cleaned.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] In this scheme, when the high-pressure nozzle is deflected, the micro motor is powered on and started, and the output end of the micro motor drives the screw to rotate. The screw pushes the slider to rise and fall by sliding with the slider, and the slider pushes and pulls the connecting rod assembly, thereby driving the high-pressure nozzle and the hollow shaft to rotate. At the same time, the two screws and the sliding cooperation of the two sliders are used to lock the deflection angle of the two high-pressure nozzles, so that the two can perform fixed-angle spraying. When both high-pressure nozzles are deflected, the two high-pressure nozzles can be deflected from 45 degrees to minus 45 degrees. The two high-pressure nozzles are deflected to the atomization drop height required by the corresponding molten metal liquid. When the two high-pressure nozzles are deflected to the angle required by the molten metal liquid, the high-pressure water vapor sprayed by the two high-pressure nozzles is the atomization drop height required by the corresponding molten metal liquid. By making the high-pressure nozzle adjustable, the high-pressure nozzle can adapt to the spray angles of different metal atomization powder makings, and adapt to the optimal spray angles and heights of different metal molten pourings. When the production is switched between different metal atomization powder makings, the metal powder manufacturing efficiency is improved.

[0037] In this solution, during the lifting and lowering process of the two high-pressure nozzles, the output ends of the multiple cylinders are extended and retracted, and the multiple cylinders lift the multiple lifting sleeves, thereby fine-tuning the height of the two high-pressure nozzles in the atomization tank, controlling the distance between the intersection of the two high-pressure nozzles and the bottom of the heating kettle, and adapting to the height requirements of the asynchronous metal atomization falling height. By lifting and lowering the lifting sleeves, the height of the two high-pressure nozzles is precisely adjusted, thereby improving the precise impact of the metal powder manufacturing device on the molten metal liquid, making the metal powder manufactured by the atomization method uniform in size and specifications, and realizing the refinement of the metal powder.

[0038] In this scheme, during the cleaning process of the metal powder on the inner wall of the atomizer tank, the motor is powered on and started, and the output end of the motor drives the driven gear to rotate, and the driven gear drives the driven gear to rotate by meshing with the driving gear, and the driven gear drives the rotating drum to rotate in the atomizer tank, and the rotating drum drives the lifting sleeve to rotate through the lifting assembly, and then drives the two high-pressure nozzles to rotate in the atomizer tank. The two high-pressure nozzles rotate to evenly spray high-pressure water vapor on the circumferential inner wall of the atomizer tank, and the metal powder on the inner wall of the atomizer tank is fully cleaned, so that the metal powder manufacturing device has a self-cleaning function, can quickly evacuate the metal powder in the atomizer tank, avoid mixing of different metal powders, improve the purity of the metal powder, and then improve the quality of the metal powder product.
