Description

Technical Field

[0001] This utility model relates to the field of slag grinding technology, and in particular to a slag powder circulating granulation grinding mill. Background Technology

[0002] Slag is a byproduct of the blast furnace ironmaking process. During ironmaking, iron oxide is reduced to metallic iron at high temperatures. Impurities such as silica and alumina in the iron ore react with lime and other materials to form a molten material mainly composed of silicates and aluminosilicates. After quenching, it becomes a loose, porous granular material, which is blast furnace slag, or slag for short.

[0003] The slag powder circulating granulation grinding mill disclosed in Chinese patent CN219784917U can screen unground slag through the arrangement of sieve plates and through holes. Simultaneously, the housing, first motor, and auger rod allow the unground slag to be re-conveyed into the machine for further grinding, thereby improving the grinding effect. However, while solving the problem, this slag powder circulating granulation grinding mill has the following drawbacks:

[0004] This slag powder circulating granulation grinding mill uses a third motor in conjunction with a rotating rod to drive a cam to push a knocking plate, which then strikes the screen plate, thereby improving the efficiency of the ground slag falling off. However, with prolonged use, friction and impact between the cam and the knocking plate can easily cause wear on the contact surface between the cam and the knocking plate, or cause the knocking plate to bend. Consequently, under the elastic force of the spring, the striking effect of the knocking plate on the screen plate is poor, thus reducing the service life of the device. Utility Model Content

[0005] The purpose of this utility model is to at least solve one of the technical defects described in the background art.

[0006] Therefore, one objective of this utility model is to propose a slag powder circulating granulation grinding mill, which aims to solve the problem that friction and impact occur between the cam and the knocking plate in the existing slag powder circulating granulation grinding mill after long-term use, which easily causes wear on the contact surface between the cam and the knocking plate, or causes the knocking plate to bend.

[0007] To achieve the above objectives, one embodiment of this utility model provides a slag powder circulating granulation grinding mill, comprising a machine body, wherein limiting strips are symmetrically and fixedly connected inside the machine body, and a screen is slidably connected inside the limiting strips. A sliding groove is provided through one side of the machine body, and a connecting block is slidably connected inside the sliding groove. One side of the connecting block is fixedly connected to one side of the screen, and a rotating seat is fixedly connected to one side of the connecting block. A connecting rod is rotatably connected inside the rotating seat, and a rotating rod is rotatably connected to one end of the connecting rod. A turntable is fixedly connected to one side of the rotating rod.

[0008] Preferably, in any of the above embodiments, a mounting plate is fixedly connected to one side of the machine body, and a motor is fixedly installed at the top of the mounting plate. The output end of the motor is fixedly connected to one side of the turntable. The motor is a slow-speed motor, which works with the turntable to drive the rotating rod to make stable circular motion. This allows the rotating rod, in conjunction with the connecting rod, rotating seat, and connecting block, to drive the screen to reciprocate, thereby improving the efficiency of the top of the screen in removing the ground slag.

[0009] Preferably, in any of the above embodiments, two sets of fixing blocks are fixedly connected to the inner wall of the machine body, and two sets of sliding grooves are opened on opposite sides of the two sets of fixing blocks. A threaded rod is rotatably connected inside one set of sliding grooves, and a slider is threadedly connected to the threaded rod. The two sets of fixing blocks are symmetrically fixed to the inner walls of both sides of the machine body, so that the two sets of sliding grooves are kept on the same horizontal line, thereby improving the stability of the slider when it moves.

[0010] Preferably, in any of the above solutions, a limiting rod is fixedly connected inside one set of the sliding grooves, and a second slider is slidably connected to the surface of the limiting rod. A mounting box is fixedly connected to the opposite side of the second slider and the first slider. The second slider and the first slider are symmetrically arranged inside the two sets of sliding grooves. The setting of the limiting rod and the second slider can ensure that the mounting box is more stable during movement.

[0011] Preferably, in any of the above embodiments, a connecting plate is slidably connected through the bottom of the mounting box, and a trapezoidal block is fixedly connected to the bottom of the connecting plate, with the pointed end of the trapezoidal block facing downwards. Thus, when the trapezoidal block is pushed by an external force, it can drive the connecting plate to slide up and down inside the mounting box, thereby improving the stability of the device.

[0012] Preferably, in any of the above embodiments, a spring is fixedly connected to the top of the interior of the mounting box, one end of the spring is fixedly connected to the top of the connecting plate, and multiple sets of springs are arranged in a linear array to exert a continuous downward force on multiple positions of the top of the connecting plate, thereby causing the connecting plate to drive the trapezoidal block to remain protruding from the interior of the mounting box.

[0013] Preferably, in any of the above solutions, the inner wall of the mounting box is symmetrically provided with limiting grooves, and a limiting block is slidably connected inside the limiting groove. One side of the limiting block is fixedly connected to one side of the connecting plate. The setting of the limiting groove and the limiting block can support the connecting plate, prevent the connecting plate from shifting during the movement of the connecting plate inside the mounting box, and prevent the spring from bearing the weight of the connecting plate and the trapezoidal block, thereby improving the stability of the device.

[0014] Preferably, one of the above solutions is that a second motor is fixedly installed through one side of the machine body, and the output end of the second motor is fixedly connected to one end of the threaded rod. The second motor is a forward and reverse reversible motor, which can work with the threaded rod to drive the first slider to move back and forth inside the slide groove.

[0015] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0016] 1. This slag powder circulating granulation grinding mill uses a motor and a turntable to drive a rotating rod in a circular motion. The rotating rod, in conjunction with a connecting rod, drives a rotating seat to move. The rotating seat, in conjunction with a connecting block, drives a screen to move. This reciprocating motion screens the ground slag into the discharge hopper. With the help of the limiting strip, wear is minimized, thus improving the service life of the device.

[0017] 2. The slag powder circulating granulation grinding mill uses a motor 2 and a threaded rod to drive a slider 1 to move. The slider 1, in conjunction with the mounting box, drives the connecting plate to move. The connecting plate, in conjunction with the trapezoidal block, smooths the accumulated slag. When the collection box is full, it is pulled out so that the top of the collection box contacts the inclined surface of the trapezoidal block, thereby pushing the trapezoidal block to drive the connecting plate to slide inside the mounting box, making it easy to pull out the collection box and improving the practicality of the device.

[0027] like Figure 1-4 As shown, this embodiment of a slag powder circulating granulation grinding mill includes a machine body 1. A limiting strip 2 is symmetrically and fixedly connected inside the machine body 1. A screen 3 is slidably connected inside the limiting strip 2. When the screen 3 moves, it slides inside the limiting strip 2. A sliding groove 4 is provided through one side of the machine body 1. A connecting block 5 is slidably connected inside the sliding groove 4. When the connecting block 5 moves, it drives the screen 3 to move. One side of the connecting block 5 is fixedly connected to one side of the screen 3. A rotating seat 6 is fixedly connected to one side of the connecting block 5. When the rotating seat 6 moves, it drives the connecting block 5 to move. A connecting rod 7 is rotatably connected inside the rotating seat 6. When the connecting rod 7 moves, it drives the rotating seat 6 to move. A rotating rod 8 is rotatably connected to one end of the connecting rod 7. When the rotating rod 8 makes a circular motion, it drives one end of the connecting rod 7 to make a circular motion. The other end of the connecting rod 7 moves while cooperating with the rotating seat 6. A turntable 9 is fixedly connected to one side of the rotating rod 8. When the turntable 9 rotates, it drives the rotating rod 8 to make a circular motion.

[0028] Example 1: A mounting plate 10 is fixedly connected to one side of the machine body 1. A motor 11 is fixedly installed on the top of the mounting plate 10. The output end of the motor 11 is fixedly connected to one side of the turntable 9. When the motor 11 is started, it drives the turntable 9 to rotate.

[0029] Example 2: Two sets of fixing blocks 12 are fixedly connected to the inner wall of the machine body 1. Two sets of sliding grooves 13 are opened on opposite sides of the two sets of fixing blocks 12. A threaded rod 14 is rotatably connected inside one set of sliding grooves 13. A slider 15 is threadedly connected to the threaded rod 14. When the threaded rod 14 rotates, it drives the slider 15 to slide inside the set of sliding grooves 13.

[0030] Example 3: A limiting rod 16 is fixedly connected inside one set of sliding grooves 13. A second slider 17 is slidably connected to the surface of the limiting rod 16. An installation box 18 is fixedly connected to the opposite side of the second slider 17 and the first slider 15. A connecting plate 19 is slidably connected through the bottom end of the installation box 18. A trapezoidal block 20 is fixedly connected to the bottom end of the connecting plate 19. When the first slider 15 moves, it drives the installation box 18 to move. The installation box 18 drives the second slider 17 to slide on the surface of the limiting rod 16. At the same time, the installation box 18 drives the connecting plate 19 to move. The connecting plate 19 drives the trapezoidal block 20 to move.

[0031] Example 4: A spring 21 is fixedly connected to the top of the inside of the mounting box 18. One end of the spring 21 is fixedly connected to the top of the connecting plate 19. When the connecting plate 19 slides inside the mounting box 18, it compresses the spring 21.

[0032] Example 5: The inner wall of the mounting box 18 is symmetrically provided with limiting grooves 22. The limiting grooves 22 are slidably connected to the inside of the limiting grooves 22. One side of the limiting block 23 is fixedly connected to one side of the connecting plate 19. When the connecting plate 19 moves, it drives the limiting block 23 to slide inside the limiting grooves 22.

[0033] Example 6: A second motor 24 is fixedly installed through one side of the machine body 1. The output end of the second motor 24 is fixedly connected to one end of the threaded rod 14. When the second motor 24 is started, it drives the threaded rod 14 to rotate.

[0034] Example 7: A collection box 25 is slidably connected to one side of the bottom end of the machine body 1. A discharge hopper 26 is fixedly connected inside the machine body 1. When the slag that has been ground by the machine body 1 falls into the discharge hopper 26 through the screen 3, it falls into the collection box 25. However, the outlet of the discharge hopper 26 is small, which makes it easy to accumulate. As the trapezoidal block 20 moves back and forth, the trapezoidal block 20 pushes the accumulated slag to other positions inside the collection box 25. When the collection box 25 is full, the collection box 25 is pulled out so that the top of the collection box 25 contacts the inclined surface of the trapezoidal block 20, thereby pushing the trapezoidal block 20 to drive the connecting plate 19 to slide inside the mounting box 18, making it easy to pull out the collection box 25.

[0035] The working principle of this utility model is as follows: In use, firstly, the slag ground by the machine body 1 falls onto the top of the screen 3. The motor 11 is started, driving the turntable 9 to rotate. The turntable 9 drives the rotating rod 8 to rotate in a circular motion. The rotating rod 8 drives one end of the connecting rod 7 to rotate in a circular motion. The other end of the connecting rod 7 moves in conjunction with the rotating seat 6, which in turn moves the connecting block 5. The connecting block 5 then moves the screen 3. This reciprocating motion screens the ground slag into the discharge hopper 26, where it falls into the collection box 25. When slag accumulates inside the collection box 25, the second motor 24 drives the threaded rod 14 to rotate. The threaded rod 14 drives the first slider 15 to move, the first slider 15 drives the mounting box 18 to move, the mounting box 18 drives the connecting plate 19 to move, and the connecting plate 19 drives the trapezoidal block 20 to move, so that the trapezoidal block 20 smooths out the accumulated slag. When the collection box 25 is full, the collection box 25 is pulled out so that the top of the collection box 25 contacts the inclined surface of the trapezoidal block 20, thereby pushing the trapezoidal block 20 to drive the connecting plate 19 to slide inside the mounting box 18, making it easy to pull out the collection box 25. Pushing the collection box 25 into the machine body 1 is also done in the same way, which is quite convenient.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] 1. The slag powder circulating granulation grinding mill drives the turntable 9 to rotate via the starting motor 11. The turntable 9 drives the rotating rod 8 to rotate in a circular motion. The rotating rod 8 drives one end of the connecting rod 7 to rotate in a circular motion. The other end of the connecting rod 7 moves in conjunction with the rotating seat 6. The connecting rod 7 drives the rotating seat 6 to move, the rotating seat 6 drives the connecting block 5 to move, and the connecting block 5 drives the screen 3 to move. This reciprocating motion screens the ground slag into the discharge hopper 26. Under the action of the limiting strip 2, wear is reduced, thus improving the service life of the device.

[0038] 2. The slag powder circulating granulation grinding mill uses a starting motor 24 to drive the threaded rod 14 to rotate. The threaded rod 14 drives the slider 15 to move, the slider 15 drives the mounting box 18 to move, the mounting box 18 drives the connecting plate 19 to move, and the connecting plate 19 drives the trapezoidal block 20 to move. This allows the trapezoidal block 20 to smooth the accumulated slag. When the collection box 25 is full, it is pulled out so that the top of the collection box 25 contacts the inclined surface of the trapezoidal block 20. This pushes the trapezoidal block 20 to drive the connecting plate 19 to slide inside the mounting box 18, making it easier to pull out the collection box 25 and improving the practicality of the device.
