Description

Technical Field

[0001] This utility model relates to the field of mining feeding technology, and in particular to a disc feeder. Background Technology

[0002] A disc feeder, also known as a disc ore feeder, is a type of ore processing feeding equipment, which includes a drive unit and the feeder body. Figure 1 The diagram shown is a schematic of an existing disc feeder. Figure 2 The diagram shows a schematic of an existing disc feeder. For example, in a disc feeder, a motor 3 drives a disc 1 via a coupling and a reducer. An annular baffle 2 is positioned close to the disc 1, but it is not fixed to the disc 1. When the disc 1 rotates, the annular baffle 2, fixed to a support, does not rotate with the disc 1. The material inside the annular baffle 2 moves with the disc 1 towards the discharge port and is discharged through a gate or scraper. The discharge rate can be adjusted using a scraper device or a gate. Alternatively, the discharge rate can also be adjusted by regulating the motor speed. Clearly, for a disc feeder, the better the uniformity and consistency of the material particle size distribution, the more accurate the adjustment of the discharge rate. If the material particle size distribution is poor and the particle sizes are inconsistent, it becomes difficult to accurately adjust the discharge rate when adjusting the motor speed.

[0003] Disc feeders are generally suitable for materials with low adhesion. If the material is highly adhesive, it can easily stick and cause blockages at the discharge port, and it can also adhere to the disc, potentially leading to disc deformation over time. Therefore, disc feeders are generally best suited for materials with low adhesion.

[0004] However, in actual production, even materials with low cohesiveness can exhibit some degree of adhesion due to certain factors. For example, mineral sands with high moisture content are more prone to adhesion. When such materials clump together, although the distribution process on the disc can provide some crushing effect, the material's movement time on the disc is limited, thus limiting the crushing and redistribution effect. Moreover, this process also impacts the wear and lifespan of the disc. Larger particles moving on the disc tend to accelerate disc wear. Furthermore, material adhesion on the disc can cause uneven material distribution, potentially leading to disc deformation or even failure over long-term operation. Since the disc is a large component of the disc feeder, replacement obviously incurs significant costs.

[0005] This invention aims to provide a disc feeder that facilitates control of the feeding amount. While crushing materials that are stuck together, it improves the uniformity of the supplied materials to facilitate control of the feeding amount, and does not affect the service life of the disc. Utility Model Content

[0006] This invention aims to provide a disc feeder that facilitates control of the feeding amount. While crushing materials that are stuck together, it improves the uniformity of the supplied materials to facilitate control of the feeding amount, and does not affect the service life of the disc.

[0007] This utility model provides a disc feeder, comprising: a disc, which rotates under the drive of a motor, and material is added onto the disc from above the center position of the disc; an annular baffle, which is disposed on the disc and close to the surface of the disc, and has a discharge port; wherein, a central column is disposed at the center position of the disc, and a feed groove is disposed on the central column, and a screen hole is disposed on the feed groove.

[0008] Furthermore, grinding aid protrusions or grinding aid rods are provided on the inner sidewall of the pre-groove.

[0009] Furthermore, a concentrating hood is provided below the predictive trough. The material flowing out of the predictive trough falls into the concentrating hood and then falls to the center of the disc.

[0010] Furthermore, a plurality of the aforementioned grooves are provided on the central cover.

[0011] Furthermore, a gear is provided at the bottom of the disc, and the output end of the motor is connected to a bevel gear or a worm gear to drive the disc to rotate.

[0012] Furthermore, at a position where the annular baffle is close to the disk, an annular ramp surface is provided on the disk.

[0013] This utility model provides a disc feeder in which the material falls into a pre-feeding trough before falling onto the disc. Ordinary material is thrown out through the screen holes of the pre-feeding trough, while clumps of material are crushed in the pre-feeding trough, making the particle size of the material more uniform and improving the uniformity of the supplied material to facilitate control of the feed rate. At the same time, the wear pressure is transferred to the pre-feeding trough, thus reducing the wear on the disc and not affecting the service life of the disc. Attached Figure Description

[0024] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0025] Figure 1 The diagram shown is a schematic of an existing disc feeder. Figure 2 The diagram shown is a schematic of an existing disc feeder. Figure 1 and Figure 2 The disc feeder shown includes: a disc 1, which rotates under the drive of a motor 3, and material is fed onto the disc 1 from above its center; and an annular baffle 2, which is positioned above and close to the surface of the disc 1, and has a discharge port. A gear 11 is located at the bottom of the disc 1, and the output of the motor 3 is connected to a bevel gear 31 to drive the disc 1 to rotate. Alternatively, the output of the motor 3 can be connected to a worm gear to drive the disc 1 to rotate.

[0026] In use, the material falls onto the disc 1 from above the center position. Under the rotation of the disc 1, the material is distributed on the surface of the disc 1 and discharged through the discharge port.

[0027] This utility model is in Figure 1 and Figure 2 The improvement is based on the disc feeder shown, mainly in the disc 1. Figure 3 The diagram shown is a schematic representation of the disc feeder according to the first embodiment of this utility model. Figure 3As shown, a central column 5 is positioned at the center of the disc 1, and a feed trough 4 is mounted on the central column 5. The feed trough 4 has sieve holes 41. When adding material, it is first added to the feed trough 4. Material of suitable particle size can naturally pass through the sieve holes 41 and onto the disc 1. For materials that are clump together, they can undergo friction within the feed trough 4 and the sieve holes 41, achieving a crushing effect and becoming material of suitable particle size that passes through the sieve holes 41 onto the disc 1. Through friction and crushing in the feed trough 4, clumps of material are crushed into smaller particles, thereby improving the uniformity of particle size distribution and enhancing the accuracy of adjusting the discharge rate by regulating the motor speed; it also reduces the risk of material clogging at the discharge port. Furthermore, since the crushing and friction processes mainly occur within the feed trough 4, the wear burden on the disc 1 is greatly reduced, extending its service life. Furthermore, since the groove 4 is designed for pre-processing materials, even if it deforms due to wear, it will not hinder its use and can be used for a long time before needing replacement, unlike the disc 1 which needs to be replaced after minor deformation. This greatly extends the service life and maintenance cycle of the overall disc feeder.

[0028] Furthermore, such as Figure 3 As shown, grinding aids protrusions or grinding aids rods 42 are provided on the inner sidewall of the pre-drilling tank 4 to facilitate the friction and crushing of large pieces of material.

[0029] Figure 4 The diagram shown is a schematic representation of the disc feeder according to the second embodiment of this utility model. Figure 3 In the illustrated embodiment, sieve holes 41 are provided on both the bottom and sidewalls of the pre-flush groove 4. Figure 4 In the embodiment shown, a screen hole 41 is provided only at the bottom of the feed trough 4, and no screen hole 41 is provided on the side wall, so that the material is expected to fall from the screen hole 41 at the bottom to the center of the disk 1.

[0030] Figure 5 The diagram shown is a schematic representation of the disc feeder according to the third embodiment of this utility model. Further, as... Figure 5 As shown, a concentrating hood 6 is provided below the pre-feeding trough 4. The material flowing out of the pre-feeding trough 4 falls into the concentrating hood 6 and then falls to the center of the disc 1, thereby extending the distribution time of the material on the disc 1 and improving the uniformity of material distribution. Furthermore, multiple pre-feeding troughs 4 can be provided above the concentrating hood 6 to extend the material distribution time and crushing time.

[0031] Preferably, the concentrator 6 is independent of the central column 5 and is not fixed to it. The concentrator 6 is fixed to an external support, so that when the central column 5 rotates with the disc 1, the concentrator 6 does not rotate with it. If the concentrator 6 also rotates with the disc 1, it will exert centrifugal force on the material, which will be detrimental to the material's descent.

[0032] Figure 6 The diagram shown is a schematic diagram of the disc of the disc feeder according to the fourth embodiment of this utility model. Figure 7 As shown Figure 6 A schematic diagram of the annular ramp surface in the illustrated embodiment. Since the annular baffle 2 and the disc 1 are only close together but not completely fixed, a certain gap still exists between the lower end of the annular baffle 2 and the disc 1. Under the centrifugal force of the disc 1, some material will still be thrown out through the gap, resulting in material waste. Furthermore, as... Figure 6 and Figure 7 As shown, an annular ramp 12 is provided on the disk 1 at a position close to the annular baffle 2. The annular ramp 12 can block the overflowing material 7 and avoid material waste.

[0033] This utility model provides a disc feeder in which the material falls into a pre-feeding trough before falling onto the disc. Ordinary material is thrown out through the screen holes of the pre-feeding trough, while clumps of material are crushed in the pre-feeding trough, making the particle size of the material more uniform and improving the uniformity of the supplied material to facilitate control of the feed rate. At the same time, the wear pressure is transferred to the pre-feeding trough, thus reducing the wear on the disc and not affecting the service life of the disc.
