Description

Technical Field

[0001] This utility model relates to the field of steel slag tailings collection technology, and in particular to a steel slag tailings collection device. Background Technology

[0002] With the increasing competition in the steel industry, the competitive strength of steel companies is reflected in everything from raw material production to smelting processes and recycling technologies. In the converter steelmaking process, there are many unpredictable factors due to high temperatures, which bring many difficulties to the control of the blowing process. Therefore, it is inevitable that unfavorable phenomena such as splashing, re-drying, high oxygen consumption during blowing, and high iron content in the final slag will occur, ultimately leading to increased steel material consumption and increased steelmaking costs.

[0003] Traditional steel slag is directly sold to cement plants after processing. This process is not only cumbersome, but also results in a low price for steel slag tailings after investing a lot of manpower, equipment, transportation, water resources and electricity. This leads to an imbalance between input and output. In addition, steel slag contains a lot of impurities, and long-term use of screening equipment may cause the pores inside the screen plate to become clogged, making it difficult to clean.

[0004] In view of this, this paper studies and improves existing problems to provide a steel slag tailings collection device with reasonable structural design, high stability, and comprehensive application. The aim is to solve the problem and improve practical value through this technology. Utility Model Content

[0005] This invention utilizes a steel slag tailings collection device. When the screen plate reciprocates under the drive of the reciprocating screw, the screen plate continuously contacts the connecting block. When the screen plate contacts the connecting block, the connecting block flips, causing the other end of the connecting block to contact the screen plate and generate a knock, thereby vibrating the screen plate. This prevents the gaps inside the screen plate from becoming clogged due to prolonged use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel slag tailings collection device, comprising a feed inlet, a guide pipe for conveying is fixedly connected to the lower end of the feed inlet, a crusher is fixedly connected to the end of the guide pipe away from the connection point, a motor for driving is fixedly connected to one side of the crusher, a rotating shaft is provided at the output end of the motor, a pulley A is provided on the outer side of the rotating shaft, a belt for transmission is provided on the inner side of the pulley A, a pulley B is provided at the end of the belt away from the pulley A, a crushing roller is fixedly connected to one end of the rotating shaft, a reciprocating screw is fixedly connected to the inner end of the belt, a screening screen plate is provided inside the crusher, a guide block is provided on the outer side of the screen plate, a guide plate is provided on one side of the crusher, a spring rod for resetting is provided inside the guide block, a connecting block for striking is connected to the inner side of the spring rod, and a discharge port is provided at the lower end of the crusher.

[0007] Preferably, the feed inlet is connected to the crusher via a guide pipe, the inlet of which is larger than the inner diameter of the guide pipe. Two sets of motors are fixedly connected to one side of the crusher, and a fixing frame is provided at the lower end of each motor. The two sets of motors are fixed to the outer wall of the crusher via the lower fixing frame.

[0008] Preferably, the drive ends of the two sets of motors are connected to rotating shafts, which pass through the outer wall of the crusher and are connected to the internal crushing rollers. The lower outer side of the two sets of rotating shafts is fixedly connected to a pulley A, which rotates by the motor driving the rotating shaft.

[0009] Preferably, the pulley B is movably connected to the outer wall of the crusher, and there are two sets of them. The pulley B and the pulley A are connected by a belt. There are two sets of crushing rollers inside the crusher, one end of which is connected to the rotating shaft and the other end is connected to the inner wall of the crusher for fixation.

[0010] Preferably, the reciprocating screw is connected to the ball nut pair of the pulley B, extends through the outer wall of the crusher to the interior, and the reciprocating screw moves by the downward rotation of the pulley B. The screen plate is fixedly connected to the reciprocating screw, and the screen plate is inclined to the side of the guide plate.

[0011] Preferably, four sets of guide blocks are provided at the upper and lower ends of the screen plate, and the four sets of guide blocks are fixedly connected to the inner wall of the crusher. A slot is opened at the upper end of the guide block near the guide plate, and the size of the slot matches the size of the guide plate. The guide plate is fixedly connected to one side of the outer end of the crusher.

[0012] Preferably, the guide block at the lower end of the slot has a groove, and its spring rod is fixedly connected inside the groove. There are two sets of spring rods, and each set of spring rods is connected to a connecting block. The connecting block matches the size of the groove. The lower end of the crusher is fixedly connected to the discharge port.

[0013] This utility model has the following beneficial effects: When the pulley B is driven to rotate, it will drive the reciprocating screw connected to it to reciprocate. Since the reciprocating screw is fixedly connected to the screen plate, the screen plate will move synchronously when the reciprocating screw moves. The screen plate will only move between four sets of guide blocks when it moves, so the guide blocks will guide the screen plate during movement, making the screen plate more stable during movement. At the same time, the screen plate will screen the crushed tailings during movement, thereby preventing agglomeration that would prevent it from falling. Since the screen plate is set at an angle, the tailings that are not completely crushed during screening will be discharged along the angle. At the same time, when the screen plate reciprocates driven by the reciprocating screw, the screen plate will continuously contact the connecting block. When the screen plate contacts the connecting block, the connecting block will flip, so that the other end of the connecting block contacts the screen plate and knocks, thereby vibrating the screen plate and preventing the gaps inside the screen plate from becoming blocked due to prolonged use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-5 This utility model provides an embodiment of a steel slag tailings collection device, including a feed inlet 1, a guide pipe 2 for conveying is fixedly connected to the lower end of the feed inlet 1, a crusher 3 is fixedly connected to the end of the guide pipe 2 away from the connection point, a motor 4 for driving is fixedly connected to one side of the crusher 3, a rotating shaft 5 is provided at the output end of the motor 4, a pulley A6 is provided on the outer side of the rotating shaft 5, a belt 7 for transmission is provided on the inner side of the pulley A6, a pulley B8 is provided at the end of the belt 7 away from the pulley A6, a crushing roller 9 is fixedly connected to one end of the rotating shaft 5, a reciprocating screw 10 is fixedly connected to the end of the belt 7 near the inner side, a screening screen plate 11 is provided inside the crusher 3, a guide block 12 is provided on the outer side of the screen plate 11, a guide plate 13 is provided on one side of the crusher 3, a spring rod 14 for resetting is provided inside the guide block 12, a connecting block 15 for striking is connected to the inner side of the spring rod 14, and a discharge port is provided at the lower end of the crusher 3.

[0023] In an optional embodiment: the feed inlet 1 is connected to the crusher 3 via a guide pipe 2. The inlet of the feed inlet 1 is larger than the inner diameter of the guide pipe 2. Two sets of motors 4 are fixedly connected to one side of the crusher 3. A fixing frame is provided at the lower end of the motors 4. The two sets of motors 4 are fixed to the outer wall of the crusher 3 via the lower fixing frame. When in use, the tailings are put into the feed inlet 1, so that the tailings will enter the interior through the guide pipe 2 and be crushed. The inlet of the feed inlet 1 is large, so as to prevent the tailings from falling to the outside when discharging.

[0024] In an optional embodiment: the drive ends of both sets of motors 4 are connected to rotating shafts 5. The two sets of rotating shafts 5 pass through the outer wall of the crusher 3 and are connected to the inner crushing rollers 9. The lower outer side of the two sets of rotating shafts 5 is fixedly connected to pulleys A6. The pulleys A6 are driven by the motors 4 to rotate the rotating shafts 5. Since the pulleys A6 and rotating shafts 5 are connected, when the motors 4 drive the rotating shafts 5 to rotate, the pulleys A6 will drive the belt 7 to rotate synchronously. Thus, when the pulleys A6 rotate, they will drive the pulleys B8 to rotate synchronously through the belt 7.

[0025] In an optional embodiment: two sets of pulleys B8 are movably connected to the outer wall of the crusher 3. The pulleys B8 and A6 are connected by a belt 7. Two sets of crushing rollers 9 are provided inside the crusher 3. One end of the rollers is connected to the rotating shaft 5, and the other end is fixed to the inner wall of the crusher 3. When the motor 4 drives the rotating shaft 5 to rotate, the rotating shaft 5 is connected to the crushing rollers 9, so that the rotating shaft 5 will drive the crushing rollers 9 to rotate synchronously, thereby crushing the dust and steel chips inside the tailings and allowing them to enter the lower end, thus facilitating their subsequent separation and collection.

[0026] In an optional embodiment: the reciprocating screw 10 is connected to the ball nut pair of the pulley B8, extending through the outer wall of the crusher 3 to the interior, and the reciprocating screw 10 moves by the downward rotation of the pulley B8. The screen plate 11 is fixedly connected to the reciprocating screw 10, and the screen plate 11 is inclined to the side of the guide plate 13. When the pulley B8 is driven to rotate, it will drive the reciprocating screw 10 connected to it to reciprocate. At the same time, since the reciprocating screw 10 is fixedly connected to the screen plate 11, the screen plate 11 will move synchronously when the reciprocating screw 10 moves. When the screen plate 11 moves, it will only move between the four sets of guide blocks 12. Thus, the guide blocks 12 will guide the screen plate 11 during movement, thereby making the screen plate 11 more stable during movement. At the same time, the screen plate 11 will screen the crushed tailings during movement, thereby preventing agglomeration that would prevent it from descending. And because the screen plate 11 is set at an incline, the tailings that are not completely crushed during screening will be discharged along the incline angle.

[0027] In an optional embodiment: four sets of guide blocks 12 are provided at the upper and lower ends of the screen plate 11. The four sets of guide blocks 12 are fixedly connected to the inner wall of the crusher 3. The upper end of the guide block 12 near the guide plate 13 has a slot, the size of which matches the size of the guide plate 13. The guide plate 13 is fixedly connected to one side of the outer end of the crusher 3. Uncrushed tailings will be discharged outward through the guide plate 13, thereby preventing the accumulation of large impurities inside and causing blockage after long-term use.

[0028] In an optional embodiment: the guide block 12 at the lower end of the slot has a groove, and its spring rod 14 is fixedly connected inside the groove. There are two sets of spring rods 14, and each set of spring rods 14 is connected to a connecting block 15. The connecting block 15 matches the internal size of the groove. The lower end of the crusher 3 is fixedly connected to the discharge port 16. When the screen plate 11 reciprocates by the reciprocating screw 10, the screen plate 11 will continuously contact the connecting block 15. When the screen plate 11 contacts the connecting block 15, the connecting block 15 will flip, so that the other end of the connecting block 15 contacts the screen plate 11 and knocks, thereby vibrating the screen plate 11 and preventing the gaps inside the screen plate 11 from becoming blocked due to prolonged use. After the connecting block 15 flips, it will be reset by the spring rod 14 connected to it.

[0029] Working principle and process: The worker puts the tailings into the feed inlet 1. The tailings will enter the crusher 3 through the guide pipe 2. The motor 4 will drive the rotating shaft 5 to rotate, which will drive the internal crushing roller 9 to crush the tailings. At the same time, the rotating shaft 5 will drive the pulley A6 to rotate. The pulley A6 will drive the pulley B8 to rotate through the belt 7. The pulley B8 will drive the reciprocating screw 10 to rotate, which will drive the screen plate 11 to reciprocate. When the screen plate 11 reciprocates, it will screen the tailings crushed by the upper crushing roller 9. When large impurities cannot fall down, they will be discharged due to the tilt angle of the screen plate 11 and the guide plate 13. When the screen plate 11 reciprocates, it will continuously squeeze the connecting block 15. The connecting block 15 will continuously knock on the screen plate 11, which will make the screen plate 11 vibrate and prevent the screen plate 11 from being blocked.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
