Description

Technical Field

[0001] This invention relates to the field of automatic feeding technology, and in particular to an automatic feeding device for a sintering machine. Background Technology

[0002] A sintering machine is a device used to sinter powder or fine granular iron-containing raw materials (such as iron concentrate powder, rich ore powder, etc.) into block sintered ore through a high-temperature sintering process. It is the core equipment in the sintering process of steel production. Sintered ore is one of the main raw materials for blast furnace ironmaking. In order to ensure the stability of the uninterrupted supply of raw materials when the sintering machine is operating, it needs to be used in conjunction with an automatic feeding device.

[0003] Currently, automatic feeding devices used in sintering machines typically use high-temperature resistant conveyor belts to transport materials to the bottom of the sintering machine for ironmaking. However, due to the large weight of the iron-containing raw materials, they tend to accumulate when placed on the conveyor belt. This causes the accumulated materials to fall into the sintering machine and stick together, leading to uneven distribution of the iron-containing raw materials and quality defects after sintering, such as poor local sintering or over-firing. Therefore, we propose an automatic feeding device for sintering machines. Summary of the Invention

[0017] The beneficial effects of this invention are:

[0018] 1. The conveyor is driven by a motor to rotate the drive roller. The drive roller rotates and drives the driven roller to rotate via the conveyor belt. The conveyor belt transports the raw materials. During this process, the driven roller rotates and drives the drive wheel to rotate synchronously. The drive wheel rotates and drives the driven wheel to rotate via the synchronous belt. The driven wheel rotates and drives the cam and connecting shaft to rotate synchronously. When the cam rotates, the protrusion on its surface rotates around the connecting shaft. When the protrusion contacts the inner wall of the conveyor belt, it lifts a portion of the conveyor belt from the inside. At this time, the bottom of the conveyor belt tightens and pushes the top block to move upward, compressing the tension spring. After the protrusion separates from the conveyor belt as the cam continues to rotate, the tension spring's reset action pushes the top block to move downward, compressing the bottom of the conveyor belt and tightening the top of the conveyor belt. Through the cooperation of the cam and the top block, the top of the conveyor belt vibrates, shaking off the raw materials and preventing them from accumulating and affecting the quality after sintering.

[0019] 2. By setting a lateral leveling device, when the cam rotates, the connecting shaft rotates synchronously. The rotation of the connecting shaft drives the first bevel gear to rotate, the first bevel gear to rotate, the second bevel gear to rotate, the second bevel gear to rotate, the drive shaft to rotate, the drive shaft to rotate, the third bevel gear to rotate, the third bevel gear to rotate, the fourth bevel gear to rotate, and the fourth bevel gear to rotate, which in turn drives the connecting shaft to rotate. The reciprocating screw rotates and drives the upper connecting plate to move laterally reciprocally via the crescent pin. The movement of the upper connecting plate drives the lower connecting plate to move laterally synchronously. The movement of the lower connecting plate drives the push rod to move laterally reciprocally synchronously, thereby spreading the raw material on the surface of the conveyor belt from the bottom, thereby increasing the uniformity of the raw material at the bottom and improving the sintering quality.

[0020] 3. By setting a leveling auxiliary device, when the upper connecting plate reciprocates laterally inside the mounting shell, the spur gear rotates under the action of the rack. The rotation of the spur gear drives the threaded rod to rotate. The rotation of the threaded rod drives the lower connecting plate to move upward through the internal thread. The upward movement of the lower connecting plate drives the push rod to move upward. When the upper connecting plate reciprocates laterally, the spur gear rotates in both directions under the action of the rack, thereby driving the push rod to move upward or downward synchronously when it moves laterally inside the raw material. This increases the contact range between the push rod and the raw material, further improving the uniformity of the raw material and preventing the occurrence of poor sintering.

[0021] 4. By setting up a combined regulator, before feeding raw materials, the operator can rotate the linkage rod to move multiple sets of linkage plates into the interior of multiple mounting shells through multiple sets of second internal threads. The movement of the linkage plates causes the adjusting block to move below the drive frame, pushing the drive frame to continue rotating around the mounting base. When the drive frame rotates, its upper end will push the linkage chamber downward, thereby pushing the push rod downward, realizing the adjustment of the lowest point of the push rod's horizontal displacement. The structure of multiple sets of threaded grooves enables synchronous adjustment of multiple push rods. By setting different thread pitches, the progressive adjustment of the lowest point of the horizontal displacement of multiple push rods can be achieved, performing staged sorting of the raw material pile from top to bottom, further improving the uniformity of the raw materials on the conveyor belt, reducing the burden on a single push rod when working, and extending the service life of the equipment.

[0039] Example 1

[0040] Please see Figures 1 to 11 This embodiment provides an automatic feeding device for a sintering machine, including: a frame 1 and side baffles 2 symmetrically fixedly connected to the top two ends of the frame 1, with mounting plates 3 fixedly connected to the top of each of the two sets of side baffles 2;

[0041] The conveyor is located between and connected to two sets of side baffles 2. It is used to convey materials. A transverse leveler is located inside and outside the side baffles 2 and connected to the conveyor. It is used to laterally level and comb the materials. A leveling aid is located and connected to the transverse leveler to improve the contact between the transverse leveler and the materials. A combined adjuster is connected to the transverse leveler and is used to adjust the minimum horizontal height of the transverse leveler. The conveyor includes a driven roller 9 rotatably connected to one side between the two sets of side baffles 2, and a driving roller 8 rotatably connected to the other side between the two sets of side baffles 2. Both the driven roller 9 and the driving roller 8 are rotatably connected to the side baffles 2 via rotating shafts. A drive motor 5 is fixedly installed at one end of the outer wall of one set of side baffles 2. The output end of the drive motor 5 is connected to the rotating shaft at the rotatable connection between the driving roller 8 and the side baffle 2. The outer wall of the roller 8 is fitted with a conveyor belt 4. One end of the outer wall of the driven roller 9 is fixedly connected to a drive wheel 10. The conveyor also includes an inner mounting plate 15 located inside the conveyor belt 4 and fixedly connected to two sets of side baffles 2. The bottom of the inner mounting plate 15 is fixedly connected to a mounting cover 14. The inside of the mounting cover 14 is movably provided with a top block 13 extending to the bottom of the mounting cover 14. Multiple sets of tension springs 23 are equidistantly arranged inside the mounting cover 14. The tension springs 23 are located between the top block 13 and the inner mounting plate 15, and the two ends of the tension springs 23 are fixed to the inner mounting plate 15 and the top block 13 respectively. The bottom of the top block 13 is in contact with the conveyor belt 4. A connecting shaft 27 is rotatably connected between the two sets of side baffles 2. A cam 17 located on one side of the mounting cover 14 is fixedly connected to the outer wall of the connecting shaft 27. A protrusion 18 is provided on the outer surface of the cam 17. One end of the outer wall of the cam 17 is fixedly connected to a driven wheel 12. The outer walls of the driven wheel 12 and the drive wheel 10 are fitted with a synchronous belt 11.

[0042] First, before sintering, the workers pour the raw materials onto the starting end of the top of the conveyor belt 4. The driven roller 9 is located at the bottom of the starting end. Then, the drive motor 5 is operated by an external controller. The drive motor 5 drives the driving roller 8 to rotate. The rotation of the driving roller 8 drives the driven roller 9 to rotate via the conveyor belt 4. The operation of the conveyor belt 4 is used to transport the raw materials. During this process, the rotation of the driven roller 9 drives the driving wheel 10 to rotate synchronously. The rotation of the driving wheel 10 drives the driven wheel 12 to rotate via the synchronous belt 11. The rotation of the driven wheel 12 drives the cam 17 and the connecting shaft 27 to rotate synchronously. At this time, when the cam 17 rotates... The protrusion 18 on its surface rotates around the connecting shaft 27. When the protrusion 18 contacts the inner wall of the conveyor belt 4, it will partially lift the conveyor belt 4 from the inside. At this time, the bottom of the conveyor belt 4 tightens and pushes the top block 13 to move upward, which will compress the tension spring 23. After the protrusion 18 separates from the conveyor belt 4 as the cam 17 continues to rotate, the reset action of the tension spring 23 pushes the top block 13 to move downward, which will compress the bottom of the conveyor belt 4 and tighten the top of the conveyor belt 4. Through the cooperation of the cam 17 and the top block 13, the top of the conveyor belt 4 will vibrate to shake off the raw materials and avoid the accumulation of raw materials, which will affect the quality after sintering.

[0043] Example 2

[0044] The lateral leveling device includes a first bevel gear 19 fixedly connected to one side of the outer wall of the connecting shaft 27. The first bevel gear 19 is located on the side of the two sets of side baffles 2 that are far apart from each other. A drive shaft 7 is rotatably connected to the outer wall of one set of side baffles 2. A second bevel gear 20 that meshes with the first bevel gear 19 is fixedly connected to the lower end of the drive shaft 7. A third bevel gear 21 is fixedly connected to the upper end of the drive shaft 7. Multiple sets of mounting shells 6 are fixedly connected at equal distances to the top of the two sets of mounting plates 3. A reciprocating screw 31 is rotatably connected inside each set of mounting shells 6. A fourth bevel gear 22 that meshes with the third bevel gear 21 is fixedly connected to one side of the outer wall of the reciprocating screw 31. An upper connecting plate 25 is movably disposed inside the mounting shell 6 outside the reciprocating screw 31. Below, there is a linkage chamber 37 extending to the bottom of the mounting housing 6. Inside the linkage chamber 37, there is a lower connecting plate 26 extending to the bottom of the linkage chamber 37. The bottom of the lower connecting plate 26 is fixedly connected to a push rod 24. The upper end of the upper connecting plate 25 has an opening extending to both sides of the outer wall of the upper connecting plate 25. The opening matches the rack 28. The rack 28 passes through the opening and penetrates the inside and outside of the upper connecting plate 25. The top of the inside of the upper connecting plate 25 is provided with a crescent pin that matches the reciprocating screw 31. The upper connecting plate 25 is movably sleeved on the outside of the reciprocating screw 31 through the crescent pin. The upper end of the lower connecting plate 26 has an internal thread that matches the threaded rod 29. The internal thread extends to the top of the upper shift chamber 16. The lower connecting plate 26 is sleeved with the threaded rod 29 through the internal thread.

[0045] When the cam 17 rotates, the connecting shaft 27 rotates synchronously. The rotation of the connecting shaft 27 drives the first bevel gear 19 to rotate, which in turn drives the second bevel gear 20 to rotate. The rotation of the second bevel gear 20 drives the drive shaft 7 to rotate, which in turn drives the third bevel gear 21 to rotate. The rotation of the third bevel gear 21 drives the fourth bevel gear 22 to rotate, which in turn drives the connecting shaft 27 to rotate. The reciprocating screw 31 rotates and drives the upper connecting plate 25 to move laterally reciprocally via the crescent pin. The movement of the upper connecting plate 25 drives the lower connecting plate 26 to move laterally synchronously. The movement of the lower connecting plate 26 drives the push rod 24 to move laterally reciprocally synchronously, thereby spreading the raw material on the surface of the conveyor belt 4 from the bottom, thus increasing the uniformity of the raw material at the bottom and improving the sintering quality.

[0046] Example 3

[0047] The leveling aid includes a rack 28 fixedly connected inside the mounting housing 6 and located below the reciprocating lead screw 31. A threaded rod 29 extending into the lower connecting plate 26 is rotatably connected inside the upper connecting plate 25. An upper shift chamber 16 is opened inside the lower connecting plate 26. A spur gear 30 that meshes with the rack 28 is fixedly connected to the outer wall of the upper end of the threaded rod 29.

[0048] When the upper connecting plate 25 reciprocates laterally inside the mounting shell 6, the spur gear 30 rotates under the action of the rack 28. The rotation of the spur gear 30 drives the threaded rod 29 to rotate. The rotation of the threaded rod 29 drives the lower connecting plate 26 to move upward through the internal thread. The upward movement of the lower connecting plate 26 drives the push rod 24 to move upward. When the upper connecting plate 25 reciprocates laterally, the spur gear 30 rotates in both directions under the action of the rack 28, thereby driving the push rod 24 to move upward or downward synchronously when it moves laterally inside the raw material. This increases the contact range between the push rod 24 and the raw material, further improving the uniformity of the raw material and preventing poor sintering.

[0049] Example 4

[0050] Multiple sets of mounting shells 6 are equipped with joint adjusters both inside and outside. Each joint adjuster includes a mounting base 34 fixedly connected to the top of the linkage chamber 37. Second sliding seats 43, extending between the upper connecting plate 25 and the linkage chamber 37, are symmetrically and movably arranged at opposite ends of the interior of the upper connecting plate 25 and the linkage chamber 37. First sliding seats 40, extending between the upper connecting plate 25 and the linkage chamber 37, are symmetrically and movably arranged at the other opposite end of the interior of the upper connecting plate 25 and the linkage chamber 37. Two sets of second sliding seats 43 are rotatably connected to a second connecting rod 39 on their adjacent sides, and two sets of first sliding seats 40 are rotatably connected to a first connecting rod 38 on their adjacent sides. The two sets of second connecting rods 39 and first connecting rods 38 are misaligned. A drive frame 41 is rotatably connected to the outside of the mounting base 34. The drive frame 41 is inclined between the upper connecting plate 25 and the linkage chamber 37. An adjusting block 44 extending to the outside of the mounting shell 6 is located below the upper end of the first connecting rod 38. The top of the adjusting block 44 is fixedly connected to... A linkage plate 35 extends to the top of the mounting housing 6. The linkage plate 35 is located outside the mounting housing 6. The drive frame 41 has a hollow structure in the middle. A compression spring 42 is installed inside the hollow structure. The top and bottom of the compression spring 42 abut against the upper connecting plate 25 and the linkage chamber 37, respectively. Multiple sets of second sliding seats 43 are rotatably connected to second connecting rods 39 on one side close to each other. Multiple sets of mounting housings 6 are equipped with reciprocating screws 31 inside. The outer wall of the multiple sets of reciprocating screws 31 near the fourth bevel gear 22 is fixed. A drive wheel 32 is fixedly connected, and a drive belt 33 is sleeved on the outer wall of multiple sets of drive wheels 32. A linkage rod 36 is rotatably connected to the top of the mounting shell 6. Multiple sets of threaded grooves are provided on the surface of the linkage rod 36. The multiple sets of threaded grooves are evenly distributed on the surface of the linkage rod 36. The pitch of the multiple sets of threaded grooves increases along the transmission direction of 4. The interior of multiple sets of linkage plates 35 is provided with second internal threads that match the multiple sets of threaded grooves. The multiple sets of linkage plates 35 are respectively sleeved on the outer wall of the multiple sets of second internal threads through the multiple sets of second internal threads.

[0051] Before feeding the raw materials, the operator can rotate the linkage rod 36, which, through multiple sets of second internal threads, drives multiple sets of linkage plates 35 to move into the interior of multiple sets of mounting shells 6. The movement of the linkage plates 35 causes the adjusting block 44 to move below the drive frame 41, pushing the drive frame 41 to continue rotating around the mounting base 34. When the drive frame 41 rotates, its upper end will push up and push the linkage chamber 37 downward, thereby pushing the push rod 24 downward, realizing the horizontal position adjustment of the lowest point of the push rod 24 during horizontal displacement. The structure of multiple sets of threaded grooves enables synchronous adjustment of multiple sets of push rods 24. By setting different thread pitches, the adjustment can be achieved. The progressive adjustment of the horizontal position of the lowest point of the multiple sets of push rods 24 during horizontal displacement, and the staged sorting of the raw material pile from top to bottom, further improve the uniformity of the raw material on the conveyor belt 4, reduce the burden on the single set of push rods 24 when working, and extend the service life of the equipment. When the fourth bevel gear 22 drives the reciprocating screw 31 to rotate, the rotation of the reciprocating screw 31 drives a set of transmission wheels 32 to rotate synchronously. The rotation of the set of transmission wheels 32 drives the transmission belt 33 to rotate synchronously. The rotation of the transmission belt 33 drives multiple sets of transmission wheels 32 to rotate synchronously. The rotation of the multiple sets of transmission wheels 32 drives multiple sets of reciprocating screws 31 to rotate synchronously to cooperate with the horizontal leveling device.
