Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to a mixing equipment for nickel-zinc ferrite magnetic core raw materials. Background Technology

[0002] Nickel-zinc ferrite cores are electronic ceramic materials made from oxides or salts of iron, nickel, and zinc. They possess characteristics such as high resistivity, low permeability, and good temperature stability, making them widely used in high-frequency circuits. They effectively reduce eddy current losses and are suitable for frequencies ranging from 1 MHz to hundreds of megahertz. In communication equipment, they can be used to manufacture components such as high-frequency transformers, inductors, and filters; in computer and electronic equipment, they can be used to manufacture power adapters and high-frequency chokes; and in automotive electronic systems, they can be used to manufacture ignition coils and electronic control units. Nickel-zinc ferrite cores are typically manufactured using electronic ceramic processes, including raw material mixing, molding, and sintering.

[0003] When mixing the raw materials for nickel-zinc ferrite cores, there may be some large particles inside, which may prevent the various materials from being mixed evenly, resulting in an increased defect rate during the manufacturing process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a nickel-zinc ferrite core raw material mixing device, including a mixing tank, a sealing cover on the top of the mixing tank, a feed hopper fixedly connected to the top of the sealing cover, a filter assembly fixedly installed inside the mixing tank, a mixing assembly inside the mixing tank, and a discharge pipe fixedly connected to the bottom of the mixing tank.

[0005] The filter assembly includes a card plate with a through hole at the bottom of its inner wall. A fixing post is fitted inside the through hole, and an mounting sleeve is fixedly connected to the top of the fixing post. A filter plate is fixedly connected to the inner wall of the mounting sleeve, and a trapezoidal block is fixedly connected to the top of the filter plate. A limiting post is fitted to the inner wall of the fixing post, and a spring is fitted to the surface of the limiting post. An mounting plate is fixedly connected to the bottom of the spring.

[0006] The above technical solution filters the raw materials entering the mixing tank through the filter plate. At the same time, the trapezoidal block generates pressure when squeezed, which drives the spring to bounce back and forth, vibrating and filtering the raw materials. The scraper can flatten the raw materials, making them fall into the mixing tank more evenly. Meanwhile, the fixing column is sleeved inside the through hole, which makes it easy to remove the raw materials from the mixing tank after the mixing is completed, so that the filter plate can be cleaned.

[0007] As a further improvement to the above solution, the card plate is fixedly connected to the inner wall of the mixing tank.

[0008] With the above technical solution, the card plate is fixed on the inner wall of the mixing tank, which ensures the stability of the filter component in the mixing tank, so that the filtration process can proceed normally and avoids the filter component shaking or shifting during the mixing process, which would affect the filtration effect.

[0009] As a further improvement to the above solution, the number of through holes is set to several, and the several through holes are evenly distributed on the surface with respect to the center of the top of the card plate.

[0010] With the above technical solution, several through holes are symmetrically and evenly distributed on the surface around the center of the top of the plate. This design allows the raw materials to enter the filtration area more evenly through the through holes, improving filtration efficiency and avoiding uneven filtration caused by the raw materials being concentrated in one place.

[0011] As a further improvement to the above solution, the surface of the mounting plate is fixedly connected to the inner wall of the mixing tank.

[0012] With the above technical solution, the mounting plate is fixed to the inner wall of the mixing tank, providing a stable support structure for the limiting column and spring. This ensures that the filter plate can achieve a certain degree of buffering and vibration through the extension and contraction of the spring during the filtration process, thus better performing the filtration operation and ensuring the stability of the entire filter assembly.

[0013] As a further improvement to the above solution, the stirring assembly includes a fixed sleeve, a drive motor is installed on the inner wall of the fixed sleeve, a rotating rod is fixedly connected to the output end of the drive motor, a scraper is fixedly connected to the surface of the rotating rod, a threaded sleeve is fixedly connected to the surface of the rotating rod, a threaded rod is threadedly connected to the inside of the threaded sleeve, a connecting column is fixedly connected to the right end of the threaded rod, and a stirring rod is fixedly connected to the right end of the connecting column.

[0014] According to the above technical solution, the stirring assembly consists of a fixed sleeve, a drive motor, a rotating rod, a scraper, a threaded sleeve, a threaded rod, a connecting column, and a stirring rod. The drive motor drives the rotating rod to rotate, thereby causing the scraper and stirring rod to rotate. The scraper can scrape the raw material on the filter plate to prevent the raw material from accumulating on the filter plate and affecting the filtration effect; the stirring rod stirs the filtered raw material to ensure that it is fully mixed.

[0015] As a further improvement to the above solution, the fixing sleeve is fixedly connected to the top of the sealing cover, and the rotating rod passes through the filter plate.

[0016] As a further improvement to the above solution, the scraper is located above the filter plate, and the stirring rod is located below the filter plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention features a filter plate. When a drive motor is activated, its output drives a rotating rod, which in turn rotates a scraper. The scraper flattens the material above the filter plate. Simultaneously, when the scraper contacts the trapezoidal block at the top of the filter plate, the block compresses the plate downwards. This compression forces a spring at the bottom of a fixed column. When the scraper detaches from the trapezoidal block, the spring's rebound causes the filter plate to move upwards, vibrating. The material above the filter plate, filtered by the vibration, falls evenly into the mixing tank and is mixed uniformly by the stirring rod. This ensures even mixing and filtration, preventing impurities from entering the mixing tank.

[0019] This invention, by setting a threaded rod, allows the sealing cover to be removed from the top of the mixing tank after mixing is complete, thereby removing the entire filter assembly and mixing assembly from the inside of the mixing tank. By rotating the threaded rod, the threaded rod can be removed from the inside of the threaded sleeve, facilitating the subsequent replacement of the mixing rod. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Example:

[0028] Please combine Figure 1-5 This embodiment of a nickel-zinc ferrite core raw material mixing device includes a mixing tank 1, a sealing cover 2 on the top of the mixing tank 1, a feed hopper 3 fixedly connected to the top of the sealing cover 2, a filter assembly 4 fixedly installed inside the mixing tank 1, a mixing assembly 5 inside the mixing tank 1, and a discharge pipe 6 fixedly connected to the bottom of the mixing tank 1.

[0029] The filter assembly 4 includes a card plate 41. The bottom of the inner wall of the card plate 41 has a through hole 42. A fixing post 43 is sleeved inside the through hole 42. An installation sleeve 44 is fixedly connected to the top of the fixing post 43. A filter plate 45 is fixedly connected to the inner wall of the installation sleeve 44. A trapezoidal block 46 is fixedly connected to the top of the filter plate 45. A limiting post 47 is sleeved on the inner wall of the fixing post 43. A spring 48 is sleeved on the surface of the limiting post 47. An installation plate 49 is fixedly connected to the bottom of the spring 48.

[0030] The plate 41 is fixedly connected to the inner wall of the mixing tank 1.

[0031] The number of through holes 42 is set to a certain number, and the through holes 42 are evenly distributed on the surface with the top center of the card plate 41 symmetrically.

[0032] The surface of the mounting plate 49 is fixedly connected to the inner wall of the mixing tank 1.

[0033] The stirring assembly 5 includes a fixed sleeve 51, a drive motor 52 is installed on the inner wall of the fixed sleeve 51, a rotating rod 53 is fixedly connected to the output end of the drive motor 52, a scraper 54 is fixedly connected to the surface of the rotating rod 53, a threaded sleeve 55 is fixedly connected to the surface of the rotating rod 53, a threaded rod 56 is threadedly connected inside the threaded sleeve 55, a connecting post 57 is fixedly connected to the right end of the threaded rod 56, and a stirring rod 58 is fixedly connected to the right end of the connecting post 57.

[0034] The fixing sleeve 51 is fixedly connected to the top of the sealing cover 2, and the rotating rod 53 passes through the filter plate 45.

[0035] The scraper 54 is located above the filter plate 45, and the stirring rod 58 is located below the filter plate 45.

[0036] The implementation principle of the nickel-zinc ferrite core raw material stirring device in this embodiment is as follows: When mixing the raw materials, the raw materials are first put into the mixing tank 1 from the top of the feed hopper 3 and fall onto the filter plate 45. The drive motor 52 is started, and the output end of the drive motor 52 drives the rotating rod 53 to rotate. The rotation of the rotating rod 53 drives the scraper 54 to rotate synchronously. The rotation of the scraper 54 will scrape the raw materials above the filter plate 45. At the same time, when the surface of the scraper 54 contacts the trapezoidal block 46 at the top of the filter plate 45, the trapezoidal block 46 drives the filter plate 45 to press downward. The filter plate 45 is pressed and presses the spring 48 at the bottom of the fixed column 43. When the scraper 54 is separated from the surface of the trapezoidal block 46, the filter plate 45 moves upward under the rebound of the spring. The filter plate 45 vibrates, and the material above the filter plate 45 falls evenly into the mixing tank 1 after being filtered by the filter plate under the vibration, and is mixed evenly by the stirring rod 58.

[0037] After mixing is completed using the threaded rod 56, the sealing cover 2 is removed from the top of the mixing tank 1, which in turn removes the entire filter assembly 4 and mixing assembly 5 from the inside of the mixing tank 1. The threaded rod 56 is then rotated to remove it from the inside of the threaded sleeve 55, facilitating the replacement of the mixing rod 58.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
