Description

Technical Field

[0001] The invention belongs to the technical field of material dust removal, and in particular relates to a material dust removal device and a dust removal method. Background Art

[0002] With the development of green economy, the new type of iron-based nano-metal soft magnetic functional materials that have emerged and been applied in recent years have been identified as environmentally friendly and energy-saving "double green (energy-saving and environmentally friendly) new materials". After the material is heat-treated by a specific annealing process, especially by applying a magnetic field annealing process at a specific temperature, it can efficiently and stably obtain ultra-fine grains of nanometer scale (10-20nm). Such a grain size is smaller than the magnetic exchange interaction length, making it a soft magnetic alloy material with excellent characteristics such as high saturation magnetic induction intensity, high magnetic permeability, low coercive force, and low loss.

[0003] The iron-based nanocrystalline magnetic core made of this material is a key component of magnetoelectric products such as common-mode inductors, high-frequency transformers, various current transformers, magnetic amplifiers, etc. It has been widely used in many fields such as national power grid, photovoltaic power generation, rail transit, new energy vehicles, wireless charging, etc.

[0004] In the process of magnetic core processing, after the green billet is pressed, it is necessary to store the billet on a fixture rack or a material cart for a period of time. The surface of the product is completely exposed to the surrounding environment, and the dust in the air will be adsorbed on the surface of the soft ferrite, causing surface contamination of the green billet. When the soft ferrite is sintered, it is easy to cause crystal spots on the surface of the product, resulting in a low product qualification rate and serious cost impact.

[0005] The existing Chinese utility model patent with publication number CN211788626U discloses a dust-proof device for soft ferrite cores, including a dust removal duct, multiple exhaust ducts, and a dust removal box. The soft ferrite core is placed in the dust removal box, and the dust removal box can be pushed toward the dust removal duct; the bottom plate of the dust removal box is provided with an air outlet duct, and the air outlet duct is connected to a sealing docking part connected to the exhaust duct, and the sealing docking part includes a sliding tube sleeved outside the air outlet duct and an elastic member provided between the sliding tube and the bottom plate, the bottom surface of the sliding tube is inclined, and the inclination direction of the bottom surface of the sliding tube is an acute angle with the advancement direction of the dust removal box, the top surface of the exhaust duct is adapted to the bottom surface of the sliding tube, and the bottom surface of the sliding tube is provided with a sealing element; the top of the dust removal box is provided with an air inlet, and a dust removal part is provided in the air inlet. Although this scheme can effectively reduce the surface contamination of the soft ferrite core embryo, it can improve the product firing qualification rate. However, storing the magnetic cores in dust removal boxes requires a large number of dust removal boxes, and the placement of the dust removal boxes requires more area, which greatly increases the production cost.

[0006] The object of the present invention is to provide a material dust removal device, by setting a storage table, a dust cover, and a dust suction mechanism, the dust cover and the storage table enclose a dust removal chamber, the dust cover is provided with an air inlet, the air inlet is aligned with the material on the mesh, under the action of the dust suction mechanism, the airflow flowing into the dust cover from the air inlet blows away the dust on the surface of the material, so that the magnetic core is cleaned before processing, solving the problem of using a dust box to store the magnetic core in the prior art, which has high investment cost and large space occupation.
