Description

Technical Field

[0001] This invention relates to the field of pellet screening equipment technology, and more specifically, to a cloth feeding mechanism and roller screen for pellet screening. Background Technology

[0002] In the iron and steel smelting industry, iron pellets are one of the important raw materials for blast furnace ironmaking. During the production process, iron pellets need to go through a screening process to screen out the pellets that meet the particle size requirements and return the unqualified ones for reprocessing. Roller screen is the core equipment for pellet screening. Its working principle is that multiple parallel screen rollers rotate to convey the material forward. The gap between the screen rollers is the screening standard. Pellets of qualified particle size fall through the gap, while unqualified large particles continue to move forward.

[0003] In existing technologies, when screening materials using a roller screen, feeding is required first. A typical feeding device gathers the material in the middle of the roller screen via a feeding channel. Then, under gravity, the material moves downwards and is screened. However, this results in a large amount of material being screened in the middle, with less material screened on the sides. This not only affects work efficiency but also accelerates wear on the middle section of the roller screen, reducing its service life. To solve this problem, existing technologies install a spiral distributor on the feeding channel to disperse the material to both sides, thereby improving work efficiency and reducing wear. However, there is a gap between the lower end of the spiral distributor and the feeding channel. Some material passes under the spiral distributor, and even when the spiral distributor disperses the material to both sides, some material still passes under the spiral distributor. Therefore, more material passes through the middle and less passes to the sides, resulting in an unsatisfactory feeding effect. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of uneven material distribution when materials are screened using only a spiral distributor. A material distribution mechanism and roller screen for pellet screening are designed.

[0006] Furthermore, the spiral feeder includes a support frame installed above the fixed platform. A servo motor is installed on one side of the upper end of the support frame. First rolling bearings are installed on both sides of the lower end of the inclined feeding channel. A rotating shaft is provided at the lower end of the inclined feeding channel. Both ends of the rotating shaft are interference-fitted with the first rolling bearings and extend to the outside of the first rolling bearings. The rotating end of the servo motor is connected to one end of the rotating shaft through a coupling. Two spiral feeding plates are installed on the rotating shaft, and the spiral directions of the two spiral feeding plates are opposite.

[0007] Furthermore, the feeder includes an inclined moving plate located below the inclined fabric channel. A semi-circular plate is integrally formed at the lower end of the inclined moving plate, and a protective plate is integrally formed at the upper end of the semi-circular plate. Baffles are provided on both sides of the inclined fabric channel. The inner surfaces of the two baffles are respectively connected to the two side surfaces of the components consisting of the inclined moving plate, the semi-circular plate, and the protective plate. A discharge port is opened on the rear side of the semi-circular plate. A guide frame is installed on the fixed platform. The guide frame can guide the baffle. The feeding shaft is located inside the semi-circular plate and is concentrically corresponding to the semi-circular plate. Second rolling bearings are installed at both ends of the feeding shaft. The second rolling bearings are installed on the baffle.

[0008] Furthermore, the drive frame includes an electric telescopic rod installed at the lower end of the inclined fabric channel. A U-shaped push block is installed at the telescopic end of the electric telescopic rod. A push plate is provided inside the U-shaped push block. The push plate is installed on the lower surface of the inclined moving plate. One side surface of the push plate and one side surface inside the U-shaped push block are connected by a telescopic spring. Positioning blocks are provided above and below the telescopic spring. The positioning blocks are installed inside the U-shaped push block. A control button is installed on one side inside the U-shaped push block.

[0009] Furthermore, the transmission frame includes a reducer mounted on one end of the rotating shaft, the lower end of the reducer mounted on a support frame, a first bevel gear mounted on the power output end of the reducer, the first bevel gear meshing with a second bevel gear, a transmission shaft mounted on the second bevel gear, a square transmission hole opened on the inner side of the transmission shaft, a third rolling bearing mounted on the transmission shaft, the third rolling bearing mounted on the support frame via a support rod, a third bevel gear mounted on one end of the feeding shaft, the third bevel gear meshing with a fourth bevel gear, a rotating rod mounted on the fourth bevel gear, a fourth rolling bearing mounted on the rotating rod, the lower end of the fourth rolling bearing mounted on the support frame via a fixing rod, a square transmission rod mounted on the rotating rod, one end of the square transmission rod extending into the square transmission hole.

[0010] Furthermore, the guide frame includes inclined guide slides located on both sides above the fixed platform. The inclined guide slides are mounted on the fixed platform via support shafts. A guide block is installed on one side of the upper end of the baffle, and one end of the guide block extends into the inclined guide slide.

[0011] Furthermore, a discharge port is provided at the lower end of the semi-circular plate.

[0012] Furthermore, two blocks are installed on the upper surface of the inclined moving plate. The two blocks are located on both sides of the feeding trough. A telescopic plate is provided on one side of the block, and a limiting groove is provided on one side of the telescopic plate, which is opened on the rear side of the inclined fabric channel.

The inclined material guide channel has a second clearance opening on one side, and one end of the feeding shaft passes through the second clearance opening.

[0014] A roller screen, wherein the inclined guide channel guides the material discharged from the feed shaft into multiple screening rollers of the roller screen.

[0015] The beneficial effects of this invention are as follows: When the material falls above the inclined feeding channel, it moves downwards and is then dispersed to both sides by the spiral distributor. The material passes under the spiral distributor and accumulates on one side of the feeding shaft. Because the material in the middle of the inclined feeding channel falls faster than the material on both sides, it accumulates in a cone shape on one side of the feeding shaft. When the material in the middle of the inclined feeding channel reaches below the spiral distributor, it stops falling and is dispersed to both sides by the spiral distributor, achieving the function of blocking instead of dredging. This facilitates the even distribution of material on the rear side of the inclined feeding channel. The transmission frame drives the feeding shaft to rotate. When the feeding trough moves to the material side, the material enters the feeding trough and is guided into the inclined guide channel by the rotation of the feeding shaft. The inclined guide channel guides the material into the roller screen, ensuring that the material enters the roller screen evenly, thereby improving the feeding effect and extending the service life of the roller screen.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This invention provides, for example Figure 1-11 The illustrated feeding mechanism for pellet screening includes a fixed platform 1, an inclined feeding channel 2 mounted above the fixed platform 1, a spiral distributor 3 mounted at the lower end of the inclined feeding channel 2, a movable feeder 4 located at the rear of the inclined feeding channel 2, a drive frame 5 mounted at the lower end of the inclined feeding channel 2, the drive frame 5 driving the feeder 4 to move back and forth, an inclined guide channel 6 located below the feeder 4, a feed shaft 7 rotatably mounted inside the feeder 4, the feed shaft 7 having multiple feed troughs 8, the material discharged from the inclined feeding channel 2 can be intercepted by the feed shaft 7 and cause the material to accumulate, a transmission frame 9 mounted on one side of the inclined feeding channel 2, the spiral distributor 3 driving the feed shaft 7 to rotate through the transmission frame 9 when rotating, the feed shaft 7 guiding the material into the inclined guide channel 6 through the feed troughs 8 when rotating.

[0020] The material distribution process of this feeding mechanism is as follows: Material is guided into the upper part of the inclined feeding channel 2 by mechanical equipment. Under the action of the inclined surface, the material slides downwards through the gap between the spiral distributor 3 and the inclined feeding channel 2. The material is then blocked by the feeding shaft 7. Activating the spiral distributor 3 causes the material to move to both sides of the spiral distributor 3, allowing it to slide down from below, thus quickly distributing the material. When the material falls to one side of the feeding shaft 7 and accumulates, because the material in the middle of the inclined feeding channel 2 flows faster than the material on the sides, the material accumulates in a cone shape on one side of the feeding shaft 7. When the material accumulates to the spiral distributor 7 in the middle of the inclined feeding channel 2, the material accumulates further. When the material is below the feeder 3, it no longer falls. The material can then be dispersed to both sides by the spiral distributor 3, achieving the function of blocking instead of dispersing, which facilitates uniform material distribution. When the spiral distributor 3 rotates, the transmission frame 9 drives the feeding shaft 7 to rotate. When the feeding trough 8 on the feeding shaft 7 rotates to the rear of the material, the material can enter the feeding trough 8. Then, when the feeding shaft 7 rotates, the material can be guided into the inclined guide channel 6 through the feeding trough 8. Under the action of the inclined surface of the inclined guide channel 6, the material can slide into the roller screen. The distance between the feeder 4 and the feeding shaft 7 and the spiral distributor 3 can be adjusted by the drive frame 5, which is convenient to adjust the appropriate distance according to the weight, size, humidity and other factors of the material, which can enhance the effect of uniform material distribution.

[0021] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 6 Included with instruction manual Figure 7 The spiral feeder 3 includes a support frame 10 mounted on the fixed platform 1. A servo motor 11 is mounted on one side of the upper end of the support frame 10. First rolling bearings 12 are mounted on both sides of the lower end of the inclined feeding channel 2. A rotating shaft 13 is provided at the lower end of the inclined feeding channel 2. Both ends of the rotating shaft 13 are interference-fitted with the first rolling bearings 12 and extend to the outside of the first rolling bearings 12. The rotating end of the servo motor 11 is connected to one end of the rotating shaft 13 through a coupling. Two spiral feeding plates 14 are mounted on the rotating shaft 13. The spiral directions of the two spiral feeding plates 14 are opposite.

[0022] The process of the spiral feeder 3 dispersing the material is as follows: When the material moves to one side of the rotating shaft 13, the servo motor 11 is started to rotate. The servo motor 11 can drive the rotating shaft 13 and the spiral feeding plate 14 to rotate. The spiral directions of the two spiral feeding plates 14 are opposite, which makes it easier for the material to move to both sides. When the material on one side of the feeding shaft 7 accumulates below the rotating shaft 13, the rotating shaft 13 can drive the spiral feeding plate 14 to rotate and disperse the material to both sides, and prevent the material from falling from the middle.

[0023] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 3 Instruction manual attached Figure 6 Included with instruction manual Figure 7 The feeder 4 includes an inclined moving plate 15 located below the inclined fabric channel 2. A semi-circular plate 16 is integrally formed at the lower end of the inclined moving plate 15, and a protective plate 17 is integrally formed at the upper end of the semi-circular plate 16. Baffles 18 are provided on both sides of the inclined fabric channel 2. The inner surfaces of the two baffles 18 are respectively connected to the two side surfaces of the components consisting of the inclined moving plate 15, the semi-circular plate 16, and the protective plate 17. A discharge port 19 is opened on the rear side of the semi-circular plate 16. A guide frame 20 is installed on the fixed platform 1. The guide frame 20 can guide the baffles 18. The feeding shaft 7 is located inside the semi-circular plate 16 and is concentrically corresponding to the semi-circular plate 16. Second rolling bearings 21 are installed at both ends of the feeding shaft 7. The second rolling bearings 21 are installed on the baffles 18.

[0024] The feeding process of the feeder 4 and the feeding shaft 7 is as follows: the inclined moving plate 15 can receive the material discharged from the inclined material channel 2, the semi-circular plate 16 can avoid the feeding shaft 7 and make room, so that the feeding trough 8 can rotate to the lower end of the inclined moving plate 15, the protective plate 17 can prevent the material from falling from a high position, the baffle 18 can prevent the material from falling from both sides, the guide frame 20 can support and guide the feeder 4, and when the material moves to the side of the discharge port 19, the material can be discharged into the inclined guide channel 6 through the discharge port 19.

[0025] Refer to the instruction manual appendix Figure 4 Instruction manual attached Figure 5 Instruction manual attached Figure 6 Included with instruction manual Figure 7 The drive frame 5 includes an electric telescopic rod 22 installed at the lower end of the inclined fabric channel 2. A U-shaped push block 23 is installed at the telescopic end of the electric telescopic rod 22. A push plate 24 is provided inside the U-shaped push block 23. The push plate 24 is installed on the lower surface of the inclined moving plate 15. One side surface of the push plate 24 and one side surface inside the U-shaped push block 23 are connected by a telescopic spring 25. A positioning block 26 is provided above and below the telescopic spring 25. The positioning block 26 is installed inside the U-shaped push block 23. A control button 27 is installed on one side inside the U-shaped push block 23.

[0026] The process of the drive frame 5 moving the feeder 4 is as follows: The electric telescopic rod 22 is activated to extend and retract, which in turn moves the U-shaped push block 23. The push plate 24 is located inside the U-shaped push block 23. As the U-shaped push block 23 moves, the push plate 24 moves the tilting plate 15, facilitating adjustment of the distance between the feeder 4 and the screw distributor 3. When the rotation speed of the feed shaft 7 is slow, causing material accumulation, the feed shaft 7 and the feeder 4 are pushed forward and downward under the action of gravity and material compression. This causes the push plate 24 to move closer to the positioning block 26, and the telescopic spring... When the spring 25 is compressed, the push plate 24 contacts the positioning block 26, causing the push plate 24 to press the control button 27. Then, the rotation speed of the screw distributor 3 is increased through the external controller, and the rotation speed of the feeding shaft 7 is increased through the transmission frame 9, thereby quickly discharging the material. When the material between the feeding shaft 7 and the screw distributor 3 decreases, the push plate 24 is pushed back to its original position under the elastic force of the telescopic spring 25, and the control button 27 returns to its original position. Then, the rotation speed of the screw distributor 3 and the feeding shaft 7 can be reduced through the external controller, thereby reducing the material discharge speed and facilitating dynamic balance.

The lower end of the reducer 28 is mounted on the support frame 10. A first bevel gear 29 is mounted on the power output end of the reducer 28. The first bevel gear 29 meshes with a second bevel gear 30. A transmission shaft 31 is mounted on the second bevel gear 30. A square transmission hole 32 is opened on the inner side of the transmission shaft 31. A third rolling bearing 33 is mounted on the transmission shaft 31. The third rolling bearing 33 is mounted on the support frame 10 through a support rod 34. A third bevel gear 35 is mounted on one end of the feeding shaft 7. The third bevel gear 35 meshes with a fourth bevel gear 36. A rotating rod 37 is mounted on the fourth bevel gear 36. A fourth rolling bearing 38 is mounted on the rotating rod 37. The lower end of the fourth rolling bearing 38 is mounted on the support frame 10 through a fixing rod 39. A square transmission rod 40 is mounted on the rotating rod 37. One end of the square transmission rod 40 extends into the square transmission hole 32.

[0028] The process of the transmission frame 9 driving the feeding shaft 7 to rotate is as follows: When the rotating shaft 13 rotates, it can drive the power input end of the reducer 28 to rotate. After the reducer 28 reduces the speed, it can drive the first bevel gear 29 to rotate. The first bevel gear 29 and the second bevel gear 30 mesh, which can drive the second bevel gear 30 and the transmission shaft 31 to rotate. The square transmission hole 32 on the transmission shaft 31 and the square transmission rod 40 fit together, which can drive the square transmission rod 40, the rotating rod 37 and the fourth bevel gear 36 to rotate. The fourth bevel gear 36 and the third bevel gear 35 mesh, which can drive the third bevel gear 35 and the feeding shaft 7 to rotate. Through the speed reduction effect of the reducer 28, the spiral distributor 3 can quickly disperse the material, and then the feeding shaft 7 slowly feeds the material, which can make the material evenly distributed and fed.

Under normal conditions, under the elastic force of the connecting spring 48, the telescopic plate 46 can be pushed towards the block 45 and make the telescopic plate 46 contact the block 45, which facilitates the guidance of the material discharged from the spiral distributor 3 and allows the material to enter the feeding trough 8. When the feeder 4 moves, the inclined moving plate 15 can drive the block 45 to move. Under the elastic force of the connecting spring 48, the telescopic plate 46 can follow the block 45 to move, which facilitates the material to enter the feeding trough 8.
