Description

Technical Field

[0001] This invention relates to a feeding device, and more particularly to a feeding device for a rotary kiln for calcining reduced ferrotitanium powder. Background Technology

[0002] In recent years, a new process for producing reduced ferroilnia powder has emerged: rotary kilns are used. Iferroilnia ore, reducing pulverized coal, and desulfurizing agents are placed inside the rotary kiln for reduction. Currently, there are two main methods for feeding reduced ferroilnia powder. One method involves the material being stored in a silo and directly fed into the rotary kiln via a chute. This method uses an open chute, which generates dust during the material's descent. Furthermore, rotary kilns using this method have poor sealing, making them unsuitable for producing reduced ferroilnia powder. The other method involves the material in the silo being fed into a screw conveyor, which then guides the material into the rotary kiln. This method improves the kiln's sealing, but because the temperature inside the rotary kiln can reach over 1000℃, the screw conveyor is prone to deformation. Even with external insulation, the insulation needs to be replaced periodically, a complex and inconvenient process.

[0003] In related technologies, Chinese utility model patent CN208166073U discloses a feeding device for a rotary kiln used in the calcination of reduced ferrotitanium powder, comprising: a storage silo, a blower, a feed silo, an airlock, a guide chute, and a cyclone separator. The key feature is that the feeding device is a pneumatic conveying system. An airlock is installed at the bottom of the storage silo, connected to the blower via a conveying pipe. The blower is connected to the feed silo via the conveying pipe. An airlock is located at the bottom of the feed silo, connected to the kiln tail hood via a discharge port. An exhaust pipe is located at the top of the feed silo, connected to the cyclone separator. The cyclone separator has an air outlet at the top and an airlock at the bottom connected to a return pipe, which is connected to the feed silo. This patent utilizes a pneumatic conveying system, ensuring that all materials remain within the pipeline, preventing dust pollution of the production environment. The airlock installed at the silo discharge port prevents airflow between the rotary kiln and the outside environment. The feed chute has an arc-shaped structure and a baffle block at the bottom to prevent material from spilling into the kiln tail hood and to prevent material from leaking out of the rotary kiln into the kiln tail hood.

[0004] However, this patented technology has certain drawbacks, namely: the material accumulates and stagnates on the feed chute, which not only results in low feeding efficiency, but also in uneven material delivery into the kiln, leading to material waste. Summary of the Invention

[0024] 2. The rotary kiln feeding device for reducing ferrotitanium powder of the present invention, through the setting of the pushing device, can drive the pusher plate to move down and press against the surface of the guide plate by only using the upward deflection movement of the guide plate, and move on the guide plate towards the kiln input end, so as to quickly and thoroughly push the material stuck on the guide plate into the kiln input end. Then the pusher plate leaves the surface of the guide plate and finally returns to the upper part of the guide plate, so that the guide plate can perform the next pushing operation when it deflects and rises again, which is convenient and efficient.

[0039] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0040] Example 1

[0041] Please combine Figures 1 to 11The rotary kiln feeding device for reducing ferroilite powder includes a kiln tail cover 2 installed at the input end of the kiln body 1. The top of the kiln tail cover 2 has a feeding port 3, which allows pneumatically conveyed materials to be fed in. Inside the kiln tail cover 2, there is a guide plate 4 located below the feeding port 3. The guide plate 4 is inclined and its lower end extends into the input end of the kiln body 1. A first actuating mechanism is installed inside the kiln tail cover 2. The first actuating mechanism can drive the guide plate 4 to reciprocate and deflect, preventing materials from being stuck on the guide plate 4, improving the material transmission efficiency and making the transmission more thorough.

[0042] A baffle block 5 is installed inside the kiln body 1. A fixed rod 13 is fixed on the baffle block 5. The lower end of the guide plate 4 is rotatably sleeved on the outer periphery of the fixed rod 13.

[0043] The first actuating mechanism includes a chute 6 vertically installed on the bottom wall of the kiln tail cover 2. A slider 7 is slidably connected in the chute 6. A top rod 8 parallel to the chute 6 is installed on the top of the slider 7. The top of the top rod 8 is rotatably connected to the bottom side of the high end of the guide plate 4. A driving component is installed in the kiln tail cover 2. The driving component can drive the slider 7 to reciprocate in the chute 6.

[0044] The drive assembly includes a motor 9, a rotating rod 10 is radially arranged on the output shaft of the motor 9, one end of the rotating rod 10 is rotatably connected to a rocker arm 11, and one end of the rocker arm 11 is rotatably connected to a slider 7.

[0045] In this embodiment, the first actuating mechanism operates as follows:

[0046] During feeding, the material falls onto the guide plate 4 through the feeding port 3. At this time, the output shaft of the control motor 9 drives the rotating rod 10 to rotate, causing the rotating rod 10 to drive the swing rod 11 to swing. The swing rod 11 drives the slider 7 to move up and down in the slide groove 6, which in turn drives the top rod 8 to drive the guide plate 4 to deflect back and forth around the fixed rod 13 at its lower end, so as to continuously change the tilt angle of the guide plate 4, thereby generating up and down shaking, preventing the material from being stuck on the surface of the guide plate 4, and improving the material transmission efficiency and effect of the guide plate 4.

[0047] Example 2

[0048] This embodiment is an improvement on embodiment 1. In order to further avoid material stagnation on the surface of the guide plate 4 and further improve the material transmission efficiency and effect of the guide plate 4, the feeding device of the rotary kiln for reducing ferrotitanium powder calcination in this embodiment also includes a pushing device set on the guide plate 4. The pushing device includes a pushing plate 12 and a second action mechanism. The pushing plate 12 is set on the guide plate 4. The second action mechanism is driven by the reciprocating deflection movement of the guide plate 4. It can drive the pushing plate 12 to press against the surface of the guide plate 4 each time the guide plate 4 rises, and move the surface of the guide plate 4 toward the input end of the kiln body 1 to push the material stagnation on the guide plate 4 into the input end of the kiln tail cover 2.

[0049] The second actuating mechanism includes a fixed tooth 14, a first movable tooth 16, a conversion component, and a transmission component. The fixed tooth 14 is sleeved and fixed on the fixed rod 13. The first movable tooth 16 is rotatably disposed on the side wall of the guide plate 4 and meshes with the fixed tooth 14. The first movable tooth 16 is driven by the deflection movement of the guide plate 4 and can move around the outer periphery of the fixed tooth 14 and mesh with it.

[0050] Both the conversion component and the transmission component are mounted on the guide plate 4. The conversion component can transmit the rotational action generated by the first moving tooth 16 when the guide plate 4 rises to the input end of the transmission component. The output end of the transmission component can drive the push plate 12 to press against the surface of the guide plate 4 and move towards the input end of the kiln body 1.

[0051] Positioning grooves 15 are fixed on the four side walls of the guide plate. The first moving tooth 16 is rotatably engaged with the positioning grooves 15 to realize the rotation of the first moving tooth 16 on the four side walls of the guide plate.

[0052] The conversion component includes a first disc 17 concentrically disposed on the inner periphery of the first moving tooth 16, and there is a gap (not shown) between the first disc 17 and the first moving tooth 16.

[0053] The first disc body 17 has an insert block 19 elastically arranged on its outer periphery, and the first moving tooth 16 has multiple slots 20 on its inner periphery. One side of the slot wall 20 is in frictional and pressing fit with the outer wall of the insert block 19, and the other side of the slot wall 20 is in sliding and pressurizing fit with the outer wall of the insert block 19.

[0054] A groove 18 is provided on the outer periphery of the first disc body 17, and the centripetal end of the insertion block 19 is connected to the groove 18 by a spring. When the spring is in a non-deformed state, the centrifugal end of the insertion block 19 protrudes from the outer periphery of the first disc body 17.

[0055] A ratchet 22 is concentrically fixed on the first disc body 17, and pawls 21 that cooperate with the ratchet 22 are provided on the four side walls of the guide plate. The pawls 21 are elastically deflected on the four side walls of the guide plate.

[0056] In this embodiment, it should be noted that only when the guide plate 4 deflects upwards does the first moving tooth 16 rub against and press the insert block 19 on the first disc 17 through one side of the slot wall of its upper slot 20, thereby driving the first disc 17 to rotate synchronously. At this time, the pawl 21 will not interfere with the ratchet 22 rotating synchronously with the first disc 17. That is to say, when the guide plate 4 deflects upwards, the first moving tooth 16, the first disc 17, and the ratchet 22 rotate synchronously (e.g., Figure 6 ).

[0057] Please combine Figure 11When the guide plate 4 deflects downwards, the ratchet 22 cannot rotate in the reverse direction due to the presence of the pawl 21. This also prevents the first disc 17 from rotating in the reverse direction. In this situation, the first moving tooth 16 slides and presses the insert 19 on the first disc 17 through the other side of the slot wall of its slot 20, causing the insert 19 to be pressed into the groove 18 (spring compression deformation). This avoids interfering with the rotation of the first moving tooth 16, allowing the first moving tooth 16 to rotate in the opposite direction relative to the first disc 17. Since the inner circumference of the first moving tooth 16 has multiple slots 20, after the first moving tooth 16 finishes rotating in the reverse direction, the insert 19 will be re-inserted into the slot 20 corresponding to its current position under the action of the spring, so that the first moving tooth 16 and the first disc 17 can once again form a synchronously rotating whole. In other words, when the guide plate 4 deflects downwards, the first moving tooth 16 rotates in the reverse direction, but the first disc 17 and the ratchet 22 do not rotate.

[0058] A first bevel tooth 23 is concentrically fixed on the ratchet 22, and a worm 24 is rotatably mounted on the side wall of the guide plate 4. One end of the worm 24 is provided with a second bevel tooth 25 that cooperates with the first bevel tooth 23, and the other end of the worm 24 is driven to the transmission assembly.

[0059] The transmission assembly includes a base 32 disposed on the side wall of the guide plate 4 and perpendicular to the surface of the guide plate 4. A support column 33 is disposed on the top of the base 32. A transmission rod 27 is rotatably inserted into the support column 33. One end of the transmission rod 27 is provided with a worm wheel 26 that cooperates with the worm 24, and the other end protrudes out of the support column 33 and is fixed with a third bevel tooth 28. A fourth bevel tooth 29 that cooperates with the third bevel tooth 28 is disposed on the support column 33. A synchronous shaft 30 is coaxially fixed on the fourth bevel tooth 29. A second disc 31 is sleeved and fixed on the synchronous shaft 30.

[0060] A ring body 34 is fixed on the base 32. The ring body 34 is concentrically sleeved on the outside of the second disc body 31. A ring tooth 35 is provided on the inner circumference of the ring body 34. A first connecting rod 36 is radially provided on the outer circumference of the second disc body 31. A second moving tooth 37 that meshes with the ring tooth 35 is rotatably provided on the centrifugal end of the first connecting rod 36. An eccentric shaft 38 is provided on the disc surface of the second moving tooth 37.

[0061] In this embodiment, when the second moving tooth 37 moves one revolution circumferentially within the toothed ring 35 and rotates itself, the motion trajectory 44 of the eccentric shaft 38, under the combined limiting action of the limiting grooves, limiting blocks, and the second connecting rod 39, will be an equilateral triangle, and one side of this equilateral triangle will be parallel to the surface of the guide plate 4 (e.g., Figure 12 ).

[0062] The base 32 has a first limiting groove 40 parallel to the guide plate 4. A first limiting block 41 is slidably engaged in the first limiting groove 40. A second limiting groove 42 perpendicular to the first limiting groove 40 is opened on the first limiting block 41. A second connecting rod 39 is slidably inserted in the second limiting groove 42. One end of the second connecting rod 39 is rotatably sleeved on the eccentric shaft 38, and the other end is fixedly connected to a third connecting rod 43 parallel to the guide plate 4. The push plate 12 is set on the side of the third connecting rod 43 near the input end of the kiln body 1.

[0063] In this embodiment, the feeding device operates as follows:

[0064] During each deflection and reciprocating movement of the guide plate 4, the second disc 31 will rotate once in one direction when the guide plate 4 rises, but will not rotate when the guide plate 4 descends.

[0065] Specifically, whenever the guide plate 4 deflects upward, the first moving tooth 16 moves and rotates around the outer periphery of the fixed tooth 14. The first moving tooth 16 drives the first disc 17, ratchet 22, first bevel tooth 23, second bevel tooth 25, worm 24, worm wheel 26, transmission rod 27, third bevel tooth 28, fourth bevel tooth 29, synchronous shaft 30, and second disc 31 to rotate synchronously. Then, the second disc 31 drives the second moving tooth 37 to move circumferentially through the first connecting rod 36, causing the second moving tooth 37 to rotate under the meshing action of the ring tooth 35, thereby driving the eccentric shaft 38 on the tooth surface of the second moving tooth 37 to move circumferentially on its tooth surface. The second connecting rod 39 is driven by the third connecting rod 43. Under the combined limiting action of the first limiting groove 40, the first limiting block 41, and the second limiting groove 42, the second connecting rod 39 drives the push plate 12 to approach the high end of the guide plate 4 and press against the surface of the guide plate 4. Then, it drives the push plate 12 to move towards the input end of the kiln body 1, so as to quickly push the material stuck on the surface of the guide plate 4 into the kiln body 1. Afterward, the material leaves the surface of the guide plate 4 and finally returns to the top of the guide plate 4, ready for the next unidirectional single-circuit rotation of the second disc 31, so as to perform the next pushing operation on the guide plate 4 when it rises again (e.g., Figure 1-3 12).

[0066] Whenever the guide plate 4 deflects and moves downward, the second disc 31 does not rotate, so the push plate 12 is always suspended above the high end of the guide plate 4.

[0067] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
