Description

Technical Field

[0001] This utility model relates to the field of iron-silicon-aluminum soft magnetic powder production technology, and in particular to an atomizing powder-making device for iron-silicon-aluminum soft magnetic powder production. Background Technology

[0002] Iron-silicon-aluminum soft magnetic powder is widely used in various transformers and inductors. With the continuous miniaturization and high frequency of electronic products, the performance requirements of magnetic powder cores are getting higher and higher. Atomization powder making equipment can atomize molten iron-silicon-aluminum alloy into tiny particles. These particles have regular shapes and uniform particle size distribution, which is beneficial to improving the magnetic properties, flowability and compressibility of iron-silicon-aluminum soft magnetic powder. Compared with iron-silicon-aluminum powder prepared by traditional crushing method, the powder prepared by atomization method has better sphericity and the particle size distribution is closer to normal distribution, making it more suitable for manufacturing high-performance magnetic powder core products.

[0003] Currently, the most common atomizing powder-making equipment for producing iron-silicon-aluminum soft magnetic powder on the market is the water mist method. First, the metal raw material is placed in a furnace and heated to a molten state. The molten metal liquid flows out through a nozzle and is impacted and broken into tiny droplets when it encounters a high-speed moving atomizing medium. The broken metal droplets cool and solidify rapidly during flight, forming solid powder. The solidified metal powder is collected by a collection device to obtain the final atomized powder product. However, this device still has some shortcomings.

[0004] Traditional atomizing powder-making equipment for producing iron-silicon-aluminum soft magnetic powder is prone to uneven powder size after atomization due to nozzle spray speed or insufficient cooling. This requires further manual grinding or sieving. The unevenly sized magnetic powder has poor flowability in subsequent processing and is prone to clogging and clumping, affecting processing efficiency and product quality. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an atomizing powder-making device for the production of iron-silicon-aluminum soft magnetic powder, which aims to improve the situation where uneven powder size is easily caused by insufficient nozzle spray speed or cooling after atomization, which increases the workload of subsequent sieving and grading and reduces production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an atomizing powder-making device for producing iron-silicon-aluminum soft magnetic powder, comprising a housing, an atomizing component being provided inside the housing, the atomizing component including a nozzle, the nozzle being fixedly connected to the inner wall of the housing, a furnace being fixedly connected to the inner wall of the housing, a discharge port being fixedly connected to the lower surface of the furnace, a discharge pipe being fixedly connected to the lower surface of the housing, and a grinding component being provided on one side of the housing;

[0007] The grinding assembly includes a grinding disc and a grinding rod. The grinding disc is fixedly connected to a base. A fixed plate is fixedly connected to the lower surface of the base. A grinding frame is fixedly connected to the upper surface of the fixed plate. The grinding frame is located on one side of the housing. A second motor is fixedly connected to the grinding frame. The output end of the second motor is fixedly connected to one end of the grinding rod. A filter assembly is provided on one side of the discharge pipe.

[0008] Furthermore, the filter assembly includes a filter screen and a filter cartridge. The filter screen is disposed inside the filter cartridge. The filter cartridge is rotatably connected to a filter box. The filter box is connected to one end of a discharge pipe via a flange. A motor is fixedly connected to the outer wall of the filter box. The output end of the motor is fixedly connected to the filter cartridge. A discharge pipe is fixedly connected inside the filter box.

[0009] Furthermore, a fan is installed inside the housing.

[0010] Furthermore, a bracket is fixedly connected inside the housing, and blades are fixedly connected to the upper surface of the bracket.

[0011] Furthermore, a support frame is fixedly connected to the outer wall of the box, and a box cover is fixedly connected to one end of the support frame.

[0012] Furthermore, an observation window is provided on the outer wall of the enclosure.

[0013] Furthermore, a hinge is fixedly connected to the upper surface of the filter box, a door is fixedly connected to one side of the hinge, and a handle is fixedly connected to the upper surface of the door.

[0014] Furthermore, a drying cylinder is provided below the grinding assembly, a collector is provided inside the drying cylinder, a dryer is fixedly connected to the inner wall of the drying cylinder, and a water outlet pipe is fixedly connected inside the drying cylinder.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the grinding rod is driven by the second motor in the grinding assembly to rub against the grinding disc, thereby finely crushing the residual coarse particles after filtration, further improving the uniformity of powder fineness, and improving the sphericity and particle size uniformity of the powder. This helps to improve the flowability and compressibility of the powder, ensuring that the product meets the high-precision magnetic powder standard.

[0017] 2. In this utility model, the motor in the filter box drives the rotating filter cylinder, which dynamically screens through multiple layers of filter screens, eliminating the need for manual further screening after powdering. This avoids the clogging problem caused by powder accumulation in traditional static screens. The coarse powder intercepted by the filter screen is temporarily stored in the inner cavity of the filter cylinder and can be directly returned to the furnace for remelting later.
