Description

Technical Field

[0001] The utility model belongs to the technical field of ferrite production equipment, and more specifically relates to a ferrite magnetic material vibration screening device. Background Art

[0002] Ferrite is a metal oxide with ferrimagnetism. In terms of electrical properties, the resistivity of ferrite is much greater than that of metal and alloy magnetic materials, and it also has more dielectric properties. The magnetic properties of ferrite are also manifested in its high magnetic permeability at high frequencies. Therefore, ferrite has become a widely used non-metallic magnetic material in the field of high-frequency weak electricity.

[0003] In the process of preparing ferrite magnet particles, the dry process requires pelletizing of the raw materials. In order to ensure the stability of the subsequent process and process standardization, the pellets need to be screened and suitable pellets need to be selected for the subsequent process.

[0004] For example, the patent CN202316030U discloses a device for coarse crushing of soft magnetic pre-sintered materials. The application sets a screen I and a screen II with different densities and distributed up and down above the powder storage bin; at the same time, the screen is equipped with steel balls of different sizes and in a certain proportion to coarsely crush the ferrite pre-sintered materials.

[0005] Patent CN203955515U discloses a vibrating screen for a ferrite core particle production line. This application changes the overall structure of the motor and the eccentric block, changing the original eccentric block only at one end of the motor to eccentric blocks at both ends of the motor, thereby enhancing the vibration force of the vibrating screen, and the vibration force of the vibrating screen can maintain the normal operation of the vibrating screen; reducing the residence time of the spray-dried particles on the vibrating screen, reducing the return material, and increasing the number of finished particles.

[0006] In the above application, a double-layer screen can be used to screen out pellets that meet the requirements. Due to the special properties of ferrite magnetic materials, the fine powder screened out is prone to adhesion to the lower screen holes, requiring regular cleaning and maintenance. The screen layers of traditional vibrating screens are distributed up and down, making it difficult to observe the distribution of materials on the lower screen; at the same time, the cleaning operation of the lower screen also becomes more difficult.

[0042] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0043] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] The utility model is further described below in conjunction with specific embodiments.

[0045] refer to Figure 1-Figure 2 As shown, a ferrite magnetic material vibration screening device of this embodiment includes a support component 1 and a screening component 2 arranged on the support component 1. The support component 1 is used to support the screening component 2 and drive it to vibrate. The screening component 2 is used to screen the raw materials to screen out materials that meet the process conditions (meet a certain particle size).

[0046] refer to Figure 3 As shown, the screening component 2 includes a first screening part 21, a second screening part 22 and a receiving part 23, and the three parts are generally distributed in a three-layer structure. Among them, the first screening part 21 is located at the top layer, and the material first enters the first screening part 21 for the first layer screening. The screened material of the first layer is the material particles with the largest particle size. This part of the material enters the receiving part 23 of the bottom layer after screening; the screened material of the first layer is small and medium particles, and this part of the material enters the second screening part 22 located in the middle layer for further screening. The screened material of the second layer is medium particles with a particle size that meets the requirements. This part of the particles can enter the next process after screening; the screened material of the second layer is small particles. This part of the material enters the receiving part 23 and mixes with the large particles screened out of the first layer, and then is discharged.

[0047] It should be noted that the above-mentioned large, medium and small are only divided into three categories based on the relative size of the material particle size; there is no limit on the specific particle size of each type of material. The particle size of the three types of materials, especially the medium particle size materials, needs to be determined based on actual production conditions.

[0048] Specifically, refer to Figure 4 As shown, the first screening part 21 includes a first frame 211 and a first screen 212 and a first guide plate 213 disposed in the first frame 211. In other words, the bottom of the first frame 211 is composed of the first screen 212 and the first guide plate 213.

[0049] At the same time, the upper half of the first frame 211 forms a trumpet-shaped feed port. The first material guide plate 213 is provided with a first discharge channel 214, and the discharge port end of the first discharge channel 214 penetrates the second screening part 22 and extends into the receiving part 23, so that the screened material on the first screen 212 can enter the receiving part 23 through the first discharge channel 214.

[0050] Preferably, the first screen 212 and the first guide plate 213 are integrally formed. That is, the bottom of the first frame 211 is a whole plate, a portion of the whole plate is perforated to form the first screen 212, and the other portion forms the first guide plate 213. Of course, the first screen 212 and the first guide plate 213 may be spliced ​​to form the bottom of the first frame 211.

[0051] As a preferred embodiment of the first screening part 21, the side wall of the first frame 211 away from the first screen 212 is bent inward to form a triangle, and the bent side wall divides the first guide plate 213 into two parts, and each part is provided with a first discharge channel 214. Preferably, the first discharge channel 214 is arranged at the corner of the first guide plate 213, so that the two first discharge channels 214 are respectively located near the two sides of the first frame 211 to minimize interference with the second screening part 22. At the same time, the tip of the bent side wall can also divert the screened material of the first screen 212, accelerate the discharge of the material, and prevent the accumulation of the screened material.

This design makes it possible to have no or few obstructions above the second screen 222, so that the distribution of the material on the second screen 222 can be observed and cleaned up later.

[0054] A second material discharging channel 224 is provided on the other second material guide plate 223, so that the screened material on the second screen 222 can smoothly enter the next process through the channel.

[0055] refer to Figure 6As shown, in this embodiment, the receiving portion 23 includes a third frame 231 and a bottom plate arranged in the third frame 231. A third discharge channel 232 is arranged at one end of the bottom plate away from the first screening portion 21, and large particle materials entering from the first discharge channel 214 and small particle materials leaking from the second screen 222 are discharged from the third discharge channel 232.

[0056] like Figure 1 As shown, the overall shape of the receiving portion 23 is roughly the same as the shape of the second screening portion 22, except that the ends of the discharge channels of the two are far away from each other, so that the second discharge channel 224 and the third discharge channel 232 are staggered and do not interfere with each other, saving space.

[0057] As another embodiment of the screening assembly 2, a reinforcing plate 24 is provided on the third frame 231, and the reinforcing plate 24 is located directly below the second screen 222, and is used to support the second screen 222 to prevent the second screen 222 from collapsing or even being damaged due to excessive weight of the material. At the same time, in order not to interfere with the normal falling of the material under the second screen 222, the reinforcing plate 24 adopts a hollow design. Of course, in order to ensure the service life of the first screen 212, a reinforcing plate 24 can also be provided at the bottom of the first screen 212.

[0058] In addition, in order to ensure that the material can move smoothly toward the discharge channel, the entire screening assembly 2 can be tilted. The feed inlet of the first screening part is the high end, and the third discharge channel 232 is the low end. Figure 3 From the perspective of the paper, the left end is high and the right end is low.

[0059] Preferably, the inclination angle of the screening assembly 2 does not exceed 10°.

[0060] As an embodiment of the support assembly 1, refer to Figure 7 , Figure 8 As shown, the support assembly 1 includes a support frame 11 and a mounting platform 12 disposed on the support frame 11. A spring 13 is disposed between the support frame 11 and the mounting platform 12, and a vibration motor 14 is disposed on the mounting platform 12.

[0061] Furthermore, the support frame 11 includes four legs, and connecting ribs are provided between two adjacent legs to ensure the overall strength of the support frame 11. At the same time, two parallel support plates 15 are provided at the bottom of the support frame 11 to ensure the stability of the support frame 11.

[0062] The mounting platform 12 includes a set of horizontal plates 121 arranged opposite to each other and a plurality of vertical plates 122 arranged on the horizontal plates 121. The horizontal plates 121 are mounted on the top of the legs, and the bottom of the horizontal plates 121 and the top of the legs are provided with positioning bosses for the springs 13 to be mounted. The two ends of the vertical plates 122 are respectively located on the corresponding horizontal plates 121, and a plurality of reinforcing ribs 123 are provided on the portion of the vertical plates 122 located between the two horizontal plates 121. In addition, the bottom of the vertical plates 122 has an inclined surface, and the vibration motor 14 is arranged on the inclined surface through the mounting plate.

[0063] A ferrite magnetic material vibration screening device of this embodiment has the following screening process:

[0064] The material first enters the first screening part 21, and is screened by the first screen 212. The particles on the screen are particles with larger particle sizes. These particles enter the receiving part 23 through the first discharge channel 214. The particles under the screen enter the second screening part 22 for further screening.

[0065] The material entering the second screening part 22 first falls onto the second guide plate 223, and then is screened by the second screen 222; the material on the screen is particles with a moderate particle size, that is, qualified material, and this part of the material enters the next process through the second discharge channel 224; the material under the screen directly falls into the receiving part 23, mixes with the large particle material entering from the first discharge channel 214, and is discharged through the third discharge channel 232.

The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
