Description

Technical Field

[0001] The utility model relates to the field of magnetic material production, in particular to a magnetic powder mixing device. Background Art

[0002] Magnetic materials are a type of material with strong magnetism, which are widely used in electronics, electrical appliances, computers, communications, medical treatment, automobiles and other fields. The following introduces a common production process of magnetic materials.

[0003] First of all, the production of magnetic materials requires the preparation of magnetic powder. Generally, iron oxide, ferrite, ferrite, etc. are used as magnetic powders. The magnetic powders are mixed with a binder. The binder can be an organic resin, epoxy resin, etc. When mixing, it is necessary to ensure that the magnetic powder and the binder are fully and evenly distributed. Then, the mixed magnetic material is placed in a mold and pressed by a pressing machine. After the pressing is completed, the magnetic material is annealed. Therefore, the quality of the raw materials processed in the material preparation process has a certain impact on the quality of the products produced later. The mixing device is a machine in which a shaft with blades rotates in a cylinder or a groove to stir and mix a variety of raw materials to make them a mixture or a suitable consistency.

[0004] According to the search, Chinese patent literature, announcement number: CN207137744U, discloses a mixer for magnetic materials. Since baffles are provided at the four corners of the mixing barrel, the mixed and stirred materials are prevented from adhering to the side feet of the mixing barrel; and a heating tube is provided between the baffle and the mixing barrel to prevent condensation and adhesion of the materials; the heat dissipation holes on both sides of the motor can timely dissipate the heat generated during the operation of the motor, avoid overheating of the motor, and play a role in protecting the motor; the observation window on the sealing cover can timely observe the mixing situation of the materials in the mixing barrel and drain them in time. When mixing, materials such as resin will adhere to the inner wall of the mixing barrel, reducing the total amount when mixed with magnetic powder. Secondly, when discharging, the materials adhered to the inner wall of the mixing barrel cannot be quickly discharged according to their own flow characteristics, which makes it inconvenient to discharge.

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0021] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0022] Example 1

[0023] like Figure 1-3 As shown, a magnetic powder mixing device comprises a tank body, an upper cover arranged above the tank body, a plurality of bolt assemblies 2 penetrating and mounted on the edges of the tank body and the upper cover, a motor 5 is arranged at the middle of the top end of the upper cover, an agitator 7 connected to the motor 5 is arranged on the inner side of the tank body, the agitator 7 comprises a rotating shaft 72 arranged at the bottom end of the motor 5, stirring blades I 74, III 76 and II 75 sequentially sleeved on the outer side of the rotating shaft 72, a scraper 73 mounted on the rotating shaft 72 and in contact with the inner wall of the tank body, and a discharge plate 77 arranged on the outer side of the bottom end of the rotating shaft 72.

[0024] The tank body comprises a cylinder body 1 and a discharge pipe 6 which is arranged at the bottom end of the cylinder body 1 and sleeved on the outside of a discharge plate 77 .

[0025] The discharge plate 77 is spiral in shape, the rotating shaft 72 and the discharge plate 77 are both plugged into the inner side of the discharge pipe 6 , and the outer size of the agitator 7 is matched with the inner size of the discharge pipe 6 .

[0026] The upper cover comprises a cover and a cover plate 3 at the top of the tank body, and a plurality of flanges 4 which are arranged on the cover plate 3 and pass through the cover plate 3 .

[0027] The scraper 73 includes two fixing frames 731 installed outside the rotating shaft 72, a scraping plate 732 arranged at the ends of the two fixing frames 731 and in contact with the inner wall of the tank body, and a push plate 733 arranged at the bottom end of the scraping plate 732 and in contact with the bottom end of the inner wall of the tank body.

[0028] The scraper plate 732 is arranged in an inclined shape, and its edge contacts the inner wall of the cylinder 1. When the rotating shaft 72 drives the scraper plate 732 to rotate through the fixed frame 731, the scraper plate 732 scrapes the material adhered to the inner wall of the cylinder 1, so that the overall material is mixed more evenly while avoiding adhesion during discharge, causing material waste, and the cleaning of the inner wall of the cylinder 1 remains unchanged.

[0029] The stirring blades I 74 and II 75 are arranged symmetrically, the stirring blades III 76 are arranged vertically, and the rotation direction of the discharge plate 77 is the same as that of the stirring blades II 75. During stirring, the bottom end of the cylinder 1 can be sealed by the cooperation of the discharge plate 77 and the discharge pipe 6, and the magnetic powder can be moved downward by the stirring blades I 74, and the stirring blades II 75 can drive the resin to move upward to generate impact force, thereby improving the mixing uniformity. At the same time, when the resin and the magnetic powder generate impact force, the stirring blades III 76 will adjust the positions of the resin and the magnetic powder where the impact force is generated to further improve the mixing uniformity between the resin and the magnetic powder.

[0030] The upper cover also includes lifting rings 8 arranged at the top of the cover plate 3 and located on both sides of the motor 5. When cleaning the equipment, the bolt assembly 2 can be disassembled, and the upper cover connected to the agitator 7 can be separated from the cylinder 1 through lifting equipment such as a crane, so that the entire equipment can be cleaned to improve the cleanliness of the equipment.

[0031] Working principle:

[0032] When in use, the stirrer 7 is first driven by the motor 5 to work, and the organic resin or epoxy resin and other materials are injected into the inner side of the cylinder 1 through the flange 4, so that the rotating shaft 72 drives the discharge plate 77 to rotate on the inner side of the discharge pipe 6, so as to prevent the organic resin or epoxy resin and other materials from entering the inner side of the discharge pipe 6, and at the same time, the magnetic powder is transported to the inner side of the cylinder 1, so that it is driven by the stirring blade I 74 to move toward the inner side of the stirring organic resin or epoxy resin and other materials, and at the same time, the stirring blade II 75 drives the stirring organic resin or epoxy resin and other materials to move upward, so that the organic resin or epoxy resin and other materials and the magnetic powder are turned over, and at the same time, the stirring blade III 76 drives the magnetic powder and the organic resin or epoxy resin The organic resin or epoxy resin is stirred horizontally to make the organic resin or epoxy resin and the magnetic powder mixed more evenly, and the mixing time between the magnetic powder and the organic resin or epoxy resin is reduced. At the same time, the rotating shaft 72 drives the scraper 73 to move along the inner wall of the cylinder 1, so that the obliquely installed scraper plate 732 and the push plate 733 scrape the material adhering to the inner wall of the cylinder 1 to avoid errors in the mixing of the overall material. After the mixing is completed, the discharge plate 77 is turned over by the rotating shaft 72, so that the stirring blade II 75 drives the mixture to move downward, and the obliquely installed scraper plate 732 scrapes the adhering mixture on the inner wall of the cylinder 1 downward, so that the discharge of the mixture on the inner side of the cylinder 1 is more convenient, and the waste of adhesion is avoided, and the difficulty of cleaning the equipment is reduced.
