Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, and in particular to a feeding structure for a weak magnetic separator used in titanium ore production. Background Technology

[0002] Magnetic separators are screening devices used to remove iron powder and other pollutants from recycled powdery materials. After the slurry flows into the tank through the feed box, the mineral particles enter the feed area of ​​the tank in a loose state under the action of the water flow from the feed spray pipe. Under the action of the magnetic field, the magnetic mineral particles undergo magnetic aggregation to form "magnetic clusters" or "magnetic chains". The magnetic clusters or "magnetic chains" are attracted to the magnetic poles by the magnetic force in the slurry and are adsorbed onto the cylinder. Because the polarities of the magnetic poles are alternately arranged along the direction of rotation of the cylinder and remain stationary during operation, the "magnetic clusters" or "magnetic chains" generate a magnetic stirring phenomenon due to the alternating magnetic poles as the cylinder rotates. Non-magnetic minerals such as gangue trapped in the "magnetic clusters" or "magnetic chains" fall off during the agitation. The "magnetic clusters" or "magnetic chains" that are finally attracted to the surface of the cylinder are the concentrate. Magnetic separators are widely used in resource recovery, timber industry, mining, kiln industry, chemical industry, food 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. They are also used for iron removal operations of materials such as coal, non-metallic minerals, and building materials. It is one of the most widely used and versatile machines in the industry.

[0003] An existing external magnetic drum separator feeding device (publication number CN104437845B) has a magnetic box at the bottom of the slurry buffer tank, and an inlet pipe and an outlet pipe at the top and tail of the slurry buffer tank, respectively. The inlet pipe is connected to external equipment through a flange, and the outlet pipe is connected to the ore distributor through a flange. It can achieve uniform feeding along the axial direction of the external magnetic drum separator, and has good wear resistance and long service life. However, this device directly discharges large particles, which will cause waste. Utility Model Content

[0018] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified. Example

[0019] like Figure 1-3 As shown, this utility model provides a feeding structure for a weak magnetic separator used in titanium ore production, including a ore box 1. A feed inlet 10 is located on one side of the top surface of the ore box 1, and a ore distributor 17 is located below one side of the ore box 1. Movable grooves 2 are opened at the center of both sides of the inner wall, and filter plates 3 that reciprocate vertically within the movable grooves 2. A second motor 11 is fixedly installed at the center of one side of the outer surface of the ore box 1, and a first gear 12 is fixedly installed on the output shaft of the second motor 11. Rotary rods 13 are symmetrically connected to one side of the outer surface of the ore box 1 via bearings. One end of the rotating rod 13 enters the ore box 1 and is fixedly connected to several eccentric wheels 15, which contact the bottom surface of the filter plates 3. The other end of the rotating rod 13 exits the ore box 1 and is fixedly connected to the second gear. 14. The second gear 14 meshes with the first gear 12. The ore box 1 is equipped with two clamping plates 4 that are axially close to or far apart from each other. A sliding groove 6 is opened on one side of the top surface of the ore box 1. The first motor 7 is fixedly installed on one side of the top surface of the ore box 1. The output shaft of the first motor 7 is fixedly installed with a double-acting screw 8. The surface of the double-acting screw 8 is symmetrically threaded with two sliding plates 9 that are adapted to the sliding groove 6. The sliding plates 9 pass through the sliding groove 6 and enter the ore box 1 to be fixedly connected to the clamping plate 4. Several crushing drill bits 5 are provided on both sides of the clamping plate 4. The crushing drill bits 5 on the side of the clamping plate 4 that are close to each other are staggered. The bottom surface of the clamping plate 4 and the top surface of the inner wall of the movable groove 2 are at the same height, so that when the filter plate 3 moves up and down in the movable groove 2, the filter plate 3 will not collide with the clamping plate 4.

[0020] Mineral material is poured into the ore box 1 through the feed inlet 10. Small particles of mineral material fall through the filter holes of the filter plate 3, while large particles remain on the filter plate 3. The first motor 7 is started to rotate forward and backward. The first motor 7 drives the bidirectional lead screw 8 to rotate forward and backward. The bidirectional lead screw 8 drives the two slide plates 9 to move closer and further away from each other in the slide groove 6. The two slide plates 9 drive the two clamping plates 4 to move closer and further away from each other. Through the cooperation of the crushing drill bit 5, the clamping plates 4 and the inner wall of the ore box 1, the crushing of large particles of mineral material is completed.

[0021] While crushing large-particle minerals, the second motor 11 is started, which drives the first gear 12 to rotate. The first gear 12 drives the two second gears 14 to rotate, the second gears 14 drive the rotating rod 13 to rotate, the rotating rod 13 drives the eccentric wheel 15 to rotate, and the eccentric wheel 15 drives the filter plate 3 to move up and down in the movable groove 2, thereby effectively preventing the filter plate 3 from clogging and improving the filtration efficiency.

[0022] like Figure 2 As shown in the embodiment, baffles 16 are fixedly installed on both sides of the top surface of the filter plate 3. The height of the baffles 16 is greater than the height of the movable groove 2 to prevent the ore from entering the movable groove 2 and affecting the normal movement of the filter plate 3. The top surface of the baffles 16 is set as an incline, and the top surfaces of the two baffles 16 are inverted V-shape to prevent the ore from falling on the top surface of the baffles 16. One side of the baffles 16 is in contact with the inner wall of the ore box 1, and the other side of the baffles 16 is in contact with the clamping plate 4, so that the clamping plate 4 and the crushing drill bit 5 can crush all the large particles of material that fall onto the filter plate 3 after entering the ore box 1.
