[0002] Magnetic separators are used to remove iron powder and other pollutants from powdered materials. They are widely used in resource recycling, timber industry, mining, kiln industry, chemical industry, food industry and other factories. They are suitable for wet magnetic separation of materials such as magnetite, pyrrhotite, roasted ore, and ilmenite with a particle size of less than 3mm.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-7 A magnetic separator feeding device includes a feeding pipe 2 fixedly connected to the feed inlet of a magnetic separator 1. The feeding pipe 2 includes a vertical part and an inclined part connected to the lower end of the vertical part. The inclined part is connected to the feed inlet of the magnetic separator 1. A vibrating plate 3 is provided inside the feeding pipe 2. The vibrating plate 3 is located in the inclined part of the feeding pipe 2. The vibrating plate 3 slides back and forth through a reciprocating assembly 301. The vibrating plate 3 is in contact with the inclined part. The lower end of the vibrating plate 3 is located above the magnetic roller of the magnetic separator 1. A baffle 6 for uniform feeding is vertically slidable inside the feeding pipe 2. A feeding gap is provided between the lower end of the baffle 6 and the vibrating plate 3.

[0027] Understandably, by setting up the feeding pipe 2 and the vibrating plate 3, the raw material slides down the feeding pipe 2 into the magnetic separator 1 for screening. By setting up the baffle 6, a feeding gap is created between the baffle 6 and the vibrating plate 3. The speed of the raw material falling is controlled by the feeding gap, so that the raw material slides evenly onto the surface of the magnetic roller, and the magnetic separation effect of the magnetic separator 1 is optimized. The reciprocating component 301 drives the vibrating plate 3 to slide back and forth, so that the material passes smoothly through the feeding gap and avoids blockage.

[0028] Specifically, the vibratory feeder 3 has a U-shaped cross-section. The reciprocating assembly 301 includes a sliding plate 3011 fixed to the lower surface of the vibratory feeder 3. The bottom of the feeding pipe 2 has a through groove for sliding the sliding plate 3011. A mounting bracket 3012 is fixed to the lower surface of the feeding pipe 2. A turntable 3013 rotates on the surface of the mounting bracket 3012. A pull rod 3014 rotates on the surface of the turntable 3013 via a rotating shaft. The other end of the pull rod 3014 rotates on the lower surface of the sliding plate 3011. The rotating shaft is eccentrically set on the surface of the turntable 3013. The turntable 3013 is driven to rotate by a drive motor, which is fixed to the lower surface of the mounting bracket 3012.

[0029] It is understandable that the drive motor drives the turntable 3013 to rotate, which in turn drives one end of the pull rod 3014 to make a circular motion, thereby causing the pull rod 3014 to drive the sliding plate 3011 and the vibrating plate 3 to slide back and forth.

[0030] Specifically, a first guide plate 4 and two second guide plates 5 are fixed on the inner wall of the feeding pipe 2. The first guide plate 4 and the second guide plate 5 are both inclined. The upper end of the first guide plate 4 is fixed to the back of the feeding pipe 2, and the upper ends of the two second guide plates 5 are respectively fixed to both sides of the feeding pipe 2. The first guide plate 4 and the second guide plate 5 are both located in the vertical part of the feeding pipe 2.

[0031] It is understandable that by setting the first guide plate 4 and the second guide plate 5, the raw material near the side wall of the feeding pipe 2 falls towards the center through the first guide plate 4 and the second guide plate 5, thus preventing the raw material from falling outside the vibrating plate 3.

[0032] Specifically, the baffle 6 slides vertically on the vertical part of the feeding pipe 2. The baffle 6 is driven to rise and fall by an electric push rod 601, which is fixed to the surface of the feeding pipe 2. A movable plate 602 slides horizontally at the lower end of the baffle 6. Two grooves 603 are opened on the surface of the movable plate 602. Multiple limiting blocks 604 are fixed at the bottom of the baffle 6. The movable plate 602 slides on the surface of the multiple limiting blocks 604 through the grooves 603. Both ends of the movable plate 602 abut against the inner wall of the vibrating plate 3. The width of the baffle 6 is smaller than the length of the movable plate 602.

[0033] It is understandable that the baffle 6 is raised and lowered by the electric push rod 601, which facilitates the adjustment of the feeding gap and the adjustment of the material feeding speed according to the rotation speed of the magnetic roller. The moving plate 602 is in contact with the surface of the vibrating plate 3 at both ends, thus preventing the material from leaking from both ends of the moving plate 602. The moving plate 602 is driven to slide back and forth with the vibrating plate 3 by the reciprocating sliding of the vibrating plate 3.

[0034] Specifically, a material distribution plate 7 is fixed on the surface of the baffle 6. The material distribution plate 7 is an upwardly convex arc shape. Multiple through holes 701 are opened on the surface of the material distribution plate 7. The multiple through holes 701 are of different sizes, and the diameter of the through holes 701 gradually decreases from both ends to the middle. The multiple through holes 701 are arranged alternately.

[0035] Understandably, during feeding, the raw material is mostly located near the middle of the feeding pipe 2, resulting in a conical shape on the surface of the vibrating plate 3. When the material slides down the vibrating plate 3, there is more material in the middle than on the sides, leading to uneven feeding. Therefore, a distribution plate 7 and through holes 701 are set up. When the raw material enters the feeding pipe 2, it is distributed to both sides by the arc-shaped distribution plate 7, preventing the material from accumulating in the middle. By setting through holes 701 of different sizes, the material falls down through the through holes 701 when it slides down the surface of the distribution plate 7. Since the material density in the middle is high, the diameter of the through holes 701 in the middle is smaller to prevent a large amount of material from accumulating in the middle of the vibrating plate 3. The diameter of the through holes 701 at both ends of the distribution plate 7 gradually increases, so that the material is gradually and evenly spread on the surface of the vibrating plate 3 during the falling process, and then slides evenly onto the surface of the magnetic roller of the magnetic separator 1 through the vibration of the vibrating plate 3.

[0036] In this invention, during feeding, the raw material is fed in through the feeding pipe 2. Under the action of the distribution plate 7 and the through hole 701, the raw material is distributed to both sides through the arc-shaped distribution plate 7, avoiding the accumulation of raw material in the middle. The material is gradually and evenly spread on the surface of the vibrating plate 3 during the falling process. The drive motor drives the turntable 3013 to rotate, causing the turntable 3013 to drive one end of the pull rod 3014 to perform a circular motion. This causes the pull rod 3014 to drive the sliding plate 3011 and the vibrating plate 3 to slide back and forth, allowing the material to pass smoothly through the feeding gap without clogging. Then, through the vibration of the vibrating plate 3, the material slides evenly onto the surface of the magnetic roller of the magnetic separator 1. Under the action of the first guide plate 4 and the second guide plate 5, the raw material near the side wall of the feeding pipe 2 falls to the middle through the first guide plate 4 and the second guide plate 5, preventing the raw material from falling outside the vibrating plate 3. The electric push rod 601 drives the baffle 6 to rise and fall, which facilitates the adjustment of the size of the feeding gap. The feeding speed of the raw material can be adjusted according to the rotation speed of the magnetic roller.
