Description

Technical Field

[0001] This utility model relates to the field of powder processing technology, and in particular to a ferrite powder processing device. Background Technology

[0002] Ferrite is a metal oxide with subferromagnetic properties. Electrically, ferrite has a much higher resistivity than elemental metals or alloy magnetic materials, and also possesses high dielectric properties. However, due to the low magnetic energy stored per unit volume and the low saturation magnetic induction, its application in low-frequency, high-power applications requiring high magnetic energy density is limited. In powder metallurgy, powder particles need to be refined to prevent large particles from flowing into subsequent processes and interfering with production.

[0003] Existing processing equipment is generally an integrated design. After the ferrite powder is processed and ground, the powder adheres to the inner wall of the machine and cannot be completely discharged, making cleaning difficult and affecting work efficiency. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 This utility model provides an embodiment of a ferrite powder processing device, comprising a housing 1, a grinding inclined surface 2 inside the housing 1, a top cover 3 on the top of the housing 1, a grinding hammer 4 for grinding ferrite in conjunction with the grinding inclined surface 2 on the lower side of the top cover 3, a motor 5 fixedly connected to the upper side of the top cover 3, the drive end of the motor 5 fixedly connected to the top of the grinding hammer 4, a connecting ring 6 at the bottom of the housing 1, a sieve plate 7 for sieving ferrite fixedly connected to the inner wall of the connecting ring 6, a rotating shaft 8 rotatably connected to the middle of the sieve plate 7, an arc-shaped plate 9 fixedly connected to the outside of the rotating shaft 8, the lower side of the arc-shaped plate 9 closely abutting the upper side of the sieve plate 7, a scraper 10 fixedly connected to the end of the arc-shaped plate 9, the outer wall of the scraper 10 closely abutting the inner wall of the connecting ring 6, and the rotating shaft 8... A connecting rod 11 is fixedly connected to the top of the housing 1. The upper end of the connecting rod 11 passes through the inside of the grinding hammer 4. A collection hopper 12 for collecting and discharging qualified powder is fixedly connected to the bottom of the connecting ring 6. An installation plate 13 is fixedly connected to the right side of the housing 1. A connecting block 16 is provided at both the upper and lower ends of the installation plate 13. A limiting rod 15 passes through the front and rear sides of the middle of the installation plate 13. The ends of the limiting rods 15 are fixedly connected to the inside of the connecting blocks 16. An electric push rod 14 is fixedly connected to both the front and rear ends of the installation plate 13. The driving ends of the electric push rod 14 are fixedly connected to the inside of the connecting blocks 16. The connecting block 16 at the upper end of the installation plate 13 is fixedly connected to the right side of the top cover 3. The connecting block 16 at the lower end of the installation plate 13 is fixedly connected to the right side of the connecting ring 6.

[0024] The motor 5 is started, and the drive end of the motor 5 drives the grinding hammer 4 to rotate. The ferrite raw material to be processed is placed on the grinding inclined surface 2 inside the housing 1. The rotating grinding hammer 4 cooperates with the grinding inclined surface 2 to grind the ferrite raw material. As the grinding hammer 4 continues to rotate, the ferrite raw material is continuously broken into powder. The ground ferrite powder falls downward onto the sieve plate 7 inside the connecting ring 6. At the same time, when the grinding hammer 4 rotates, it drives the connecting rod 11 to rotate synchronously, which in turn causes the rotating shaft 8 to rotate. The arc plate 9 fixed outside the rotating shaft 8 rotates accordingly. The lower side of the arc plate 9 is in close contact with the upper side of the sieve plate 7. During the rotation, the powder on the sieve plate 7 is continuously ground. The powder is moved by a paddle to facilitate sieving. The scraper 10 is fixed to the end of the arc plate 9, and its outer wall fits tightly against the inner wall of the connecting ring 6. It can scrape off the powder accumulated at the edge of the sieve plate 7. Powder that meets the particle size requirements falls through the sieve plate 7 into the collection hopper 12 below and is discharged. When the device needs to be cleaned, the electric push rod 14 is activated. The electric push rod 14 located at the front end of the mounting plate 13 can drive the top cover 3 to rise, so that the grinding hammer 4 is exposed from the device for easy cleaning. The electric push rod 14 at the rear end of the mounting plate 13 can push the connecting ring 6 to fall, so that the sieve plate 7 is exposed from the device for cleaning.

[0025] Reference Figures 1-4 A base 17 is provided below the connecting ring 6. An electric slide rail 18 is fixedly connected to the right end of the base 17. A slider 19 is provided on the outside of the electric slide rail 18. The left side of the slider 19 is fixedly connected to the right side of the mounting plate 13.

[0026] At the same time, the electric slide rail 18 is activated, which can drive the slider 19 and the mounting plate 13 connected to it to move, thereby realizing the vertical position adjustment of the device, which makes it convenient for the device to work in conjunction with other equipment or adapt to different working scenarios.

[0027] Reference Figures 1-4 The left end of the connecting ring 6 is provided with a discharge port 20 for discharging unqualified powder. A guide plate 21 is fixedly connected to the left side of the connecting ring 6 corresponding to the position of the discharge port 20. An arc-shaped cover plate 22 for closing the discharge port 20 is movably connected to the left end of the connecting ring 6. A movable paddle 23 is fixedly connected to the end of the arc-shaped cover plate 22.

[0028] The qualified ferrite powder that accumulates in the collection hopper 12 is discharged through the outlet of the collection hopper 12 for subsequent collection and utilization. When it is necessary to discharge the unqualified powder left on the sieve plate 7, push the lever 23 to drive the arc-shaped cover plate 22 to rotate and open the discharge port 20. Under the action of gravity, the unqualified powder is discharged through the discharge port 20 and the guide plate 21 to the connecting ring 6. The guide plate can guide the flow of powder and prevent the powder from scattering everywhere.

[0029] Working principle: A through hole is provided in the top cover 3 for connecting the conveying pipe. Ferrite is put into the device, and the motor 5 is started to drive the grinding hammer 4 to rotate. The grinding hammer 4 cooperates with the grinding inclined surface 2 to grind the put-in ferrite. The ground ferrite powder flows out from the bottom of the grinding inclined surface 2 and falls onto the sieve plate 7. When the grinding hammer 4 rotates, it drives the scraper 10 to rotate through the connecting rod 11, thereby driving the arc plate 9 to rotate, thus driving the powder to be screened. The qualified powder passes through the sieve plate 7 and is discharged through the collection hopper 12. The arc cover 22 is opened, and the unqualified powder can be discharged through the discharge port 20 and the guide plate 21. When the device needs to be cleaned, the electric push rod 14 is started. The electric push rod 14 located at the front end of the mounting plate 13 can drive the top cover 3 to rise, so that the grinding hammer 4 is exposed in the device for easy cleaning. The electric push rod 14 at the rear end of the mounting plate 13 can push the connecting ring 6 to fall, so that the sieve plate 7 is exposed in the device for cleaning.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
