Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment technology, specifically to a feeding device for a rotary hearth furnace rotary table. Background Technology

[0002] The rotary hearth furnace direct reduction technology involves feeding iron ore powder (or laterite nickel ore, vanadium-titanium magnetite, sulfuric acid slag, or metallurgical dust, dust collector ash, steelmaking sludge, etc.) into carbon-containing pellets after batching, mixing, pelletizing, and drying. These pellets are then added to a rotary hearth furnace with an annular furnace chamber and a rotatable furnace bottom. At a furnace temperature of approximately 1350°C, the iron ore is reduced by carbon as the furnace bottom rotates once.

[0003] The installation position of the feeding device is related to the location of the rotary hearth furnace. If the feeding device is installed too high, the free fall of the pellets during the feeding process will generate a certain impact force. Excessive impact will increase the breakage rate of the pellets, affecting product quality, and long-term impact on the furnace bed will reduce the service life of the furnace bed. If the installation position is lower than near the furnace opening, the working environment temperature is high, and the stable operation of the feeding device at high temperature places high demands on the device.

[0004] During the stacking process of granular materials, due to their own physical properties, they will automatically form a stacking angle, and the cross-section of the entire material will be inverted V-shaped, resulting in more material in the middle and less material on both sides. If the material is directly spread, it will lead to uneven distribution.

[0005] Furthermore, the bottom of the rotary hearth furnace is circular, and the linear velocity at different positions is not the same. It is difficult to evenly distribute loose materials such as granules and pellets on such a continuously moving material platform with different displacement velocities at different points. If uniform, continuous, and equal-thickness material distribution cannot be achieved, the material will be heated inconsistently in the furnace, affecting the reduction quality of the material and resulting in low productivity.

[0006] In summary, this invention proposes a feeding device for a rotary hearth furnace rotary table. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a feeding device for a rotary hearth furnace rotary table, thereby solving the problems of the inability to achieve uniform, continuous, and equal-thickness material distribution in the prior art.

[0008] The prior art solution of this invention is as follows:

[0009] A feeding device for a rotary hearth furnace rotary table includes: a base, a folding assembly on the upper surface of the base, a panel connected to the folding assembly, a limit block fixedly installed on one side of the upper surface of the panel, a bracket fixedly connected to the panel, a chain conveyor fixedly connected to the upper surface of the bracket, a housing on the upper surface of the two chain conveyors, a fixing member two at the bottom of the housing, a sorting assembly on the upper surface of the fixing member two, a feed inlet on the upper surface of the housing, a fixing member one bolted to the panel, and a flipping and pushing assembly on the upper surface of the fixing member one;

[0010] A spraying machine is installed on the panel and at one end of the chain conveyor. A material platform is fixedly connected to the upper surface of the spraying machine, and the height of the material platform is the same as the height of the chain conveyor.

[0011] Furthermore, the folding assembly includes a first fixing block, a second panel, a wedge block, a panel block, and a hydraulic telescopic rod; the first fixing block is fixedly installed on the base, the second panel is fixedly connected to the upper end face of the first fixing block, the bottom end of the wedge block is bolted to the second panel, one end of the panel block is rotatably connected to the wedge block, one end of the hydraulic telescopic rod is connected to the first fixing block, and the other end is connected to the panel block.

[0012] Furthermore, the flipping and pushing assembly includes a turntable, a first motor, a second fixing block, an electric telescopic rod, and a pushing block; the turntable is fixedly mounted on a bracket, one side of the turntable is fixedly connected to the drive shaft of the first motor, the side of the turntable away from the first motor is fixedly connected to the second fixing block, the second fixing blocks are arranged in an array with the center of the turntable as the center, one end of the electric telescopic rod is fixedly connected to the second fixing block, and the other end of the electric telescopic rod is connected to the pushing block.

[0013] Furthermore, the sorting component includes a connecting block, a fourth fixing block, a first connecting column, a second connecting column, a third panel, a hydraulic rod, a third motor, a first connecting rod, and a second connecting rod; the fourth fixing block is fixedly connected to the four corners of the upper end face of the second fixing block, one side of the third fixing block is fixedly connected to the connecting block, the connecting blocks on both sides of the upper end face of the second fixing block are connected through the first connecting column, the first connecting column is connected to the hydraulic rod, the third fixing block has an arc-shaped groove, the fourth fixing block is fixedly connected to both sides of the upper end face of the second fixing block, the fourth fixing block is connected through the second connecting column, and one end of the second connecting column is fixedly connected to the drive shaft of the third motor;

[0014] Pins are fixedly connected to both sides of the panel three. The pins are rotatably connected to the bottom surface of the panel three. One end of the connecting post two is rotatably connected to the connecting rod one. The end of the connecting rod one away from the connecting post two is rotatably connected to the connecting rod two. The end of the connecting rod two away from the connecting rod one is rotatably connected to the panel three.

[0015] Furthermore, the second fixing component is kept at the same height as the chain conveyor, thereby ensuring that the electric telescopic rod and push block at the lowest point of the turntable are kept at the same height as the chain conveyor when the turntable rotates, which further facilitates the effective implementation of the device.

[0016] Furthermore, fixed blocks are fixedly connected to both sides of the upper end face of the chain conveyor to prevent materials from falling off the chain conveyor. Several rollers are provided on the upper end face of the chain conveyor to prevent materials from slipping off at an inclined angle.

[0017] Furthermore, the diameter of the arc-shaped groove is larger than the diameter of the pin, so that when the pin rotates into the arc-shaped groove, the arc-shaped groove provides support for it, which is conducive to the effective implementation of the sorting component and further improves the sorting function of the entire device, thus avoiding pellet breakage.

[0018] Furthermore, the electric telescopic rod will not affect the rotation of the turntable when it is in its original state, preventing the fixed block 2, the electric telescopic rod and the pushing block from getting stuck and affecting the operation of the device when the turntable rotates, even when the electric telescopic rod is extended or in its original state.

[0019] Furthermore, the second set of fixed blocks are arranged in an array with the center of the turntable as the center. The number of the second set of fixed blocks, the electric telescopic rod and the pushing block are the same, so as to ensure that when the turntable rotates, there is always a pushing block pushing the pellets so that they enter the rotary hearth furnace.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This invention, through the reasonable use of the folding component, reduces the impact caused by the excessively high installation position of the chain conveyor, which would increase the possibility of pellet breakage and affect product quality. Long-term impact on the furnace bed and refractory materials would also reduce the service life of the furnace bed. At the same time, it avoids the high temperature of the working environment caused by the chain conveyor being installed at a position lower than the furnace opening, which would affect the operation of the chain conveyor.

[0022] 2. This invention utilizes the rational application of the folding and pushing component. A motor drives the turntable to rotate. When the electric telescopic rod closest to the chain conveyor extends, it extends the pushing block, thereby pushing the material on the chain conveyor forward. Furthermore, as the electric telescopic rod pushes forward, the other electric telescopic rods on the turntable retract to their initial state to prevent jamming during rotation and ensure normal operation of the device. Since the turntable requires time to rotate, the electric telescopic rods effectively distribute the material evenly during their pushing process. Attached Figure Description

[0032] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0033] This invention provides a feeding device for a rotary hearth furnace rotary table, comprising: a base 1, a folding component 2 on the upper surface of the base 1, a panel 3 connected to the folding component 2, a limit block 12 fixedly installed on one side of the upper surface of the panel 3, a bracket 4 fixedly connected to the panel 3, a chain conveyor 5 fixedly connected to the upper surface of the bracket 4, a housing 8 on the upper surface of the two chain conveyors 5, a fixing member 9 at the bottom of the housing 8, the width of the fixing member 9 being equal to the distance between the two chain conveyors 5 to prevent material from falling into the device after entering from the feed inlet 11, a sorting component 10 on the upper surface of the fixing member 9, a feed inlet 11 on the upper surface of the housing 8, a fixing member 6 bolted to the panel 3, and a flipping and pushing component 7 on the upper surface of the fixing member 6;

[0034] A sprayer 15 is installed on panel 3 and at one end of the chain conveyor 5. The sprayer 15 is an existing product. A material platform 16 is fixedly connected to the upper surface of the sprayer 15. The material platform 16 is a conveyor belt. The height of the material platform 16 is the same as the height of the chain conveyor 5, and the width of the material platform 16 is equal to the total width of the two chain conveyors 5, thereby ensuring that the material on the chain conveyor 5 is transported to the material platform 16 and will not fall off during the transportation process.

[0035] The folding assembly 2 includes a fixing block 20, a panel 21, a wedge block 22, a panel block 23, and a hydraulic telescopic rod 24. The fixing block 20 is fixedly installed on the base 1, the panel 21 is fixedly connected to the upper end face of the fixing block 20, the bottom end of the wedge block 22 is bolted to the panel 21, the panel block 23 is rotatably connected to the wedge block 22, one end of the hydraulic telescopic rod 24 is connected to the fixing block 20, and the other end of the hydraulic telescopic rod 24 is connected to the panel block 23.

[0036] In one embodiment of the present invention, the hydraulic telescopic rod 24 extends and drives the panel block 23 to move in the same direction, that is, the panel block 23 tilts upward, thereby adjusting the position of the material on the chain conveyor 5 and the rotary hearth furnace. This reduces the possibility that excessive impact caused by the chain conveyor 5 being installed too high will increase the breakage rate of the pellets and affect product quality. Long-term impact on the furnace bed will also reduce the service life of the furnace bed. At the same time, it avoids the chain conveyor 5 being installed too low near the furnace opening, where the working environment temperature is high, which will affect the operation of the chain conveyor 5.

[0037] The flipping and pushing assembly 7 includes a turntable 70, a first motor 71, a second fixing block 72, an electric telescopic rod 73, and a pushing block 74. The turntable 70 is fixedly installed on the bracket 4. One side of the turntable 70 is fixedly connected to the drive shaft of the first motor 71, and the side of the turntable 70 away from the first motor 71 is fixedly connected to the second fixing block 72. One end of the electric telescopic rod 73 is fixedly connected to the second fixing block 72, and the other end of the electric telescopic rod 73 is connected to the pushing block 74.

[0038] In one embodiment of the present invention, motor 71 drives turntable 70 to rotate. When the electric telescopic rod 73 closest to the chain conveyor 5 on turntable 70 extends, it drives the pusher block 74 to extend, thereby pushing the material on the chain conveyor 5 forward. While the electric telescopic rod 73 is pushing forward, the other electric telescopic rods 73 on turntable 70 retract to their initial state to prevent jamming during rotation and affecting the normal operation of the device. Furthermore, because turntable 70 requires time to rotate, the electric telescopic rods 73 effectively distribute the material evenly during their pushing motion.

[0039] The sorting assembly 10 includes a connecting block 101, a fixing block four 102, a connecting column one 103, a connecting column two 104, a panel three 106, a hydraulic rod 107, a motor three 108, a connecting rod one 1010, and a connecting rod two 1011. The four corners of the upper end face of the fixing component two 9 are respectively fixedly connected to the fixing block three 100. One side of the fixing block three 100 is fixedly connected to the connecting block 101. The connecting block 101 is an axisymmetric graphic block, so the two sides of the connecting block 101 have the same shape. The connecting blocks 101 on both sides of the upper end face of the fixing component two 9 are connected by the connecting column one 103. The connecting column one 103 is connected to the hydraulic rod 107. The fixing block three 100 has an arc groove 109. The two sides of the upper end face of the fixing component two 9 are respectively fixedly connected to the fixing block four 102. The fixing block four 102 is connected by the connecting column two 104. One end of the connecting column two 104 is fixedly connected to the drive shaft of the motor three 108.

[0040] Pins 105 are provided on both sides of panel 3 106. Pins 105 are rotatably connected to the bottom surface of panel 3 106. One end of connecting post 2 104 is rotatably connected to connecting rod 1 1010. The end of connecting rod 1 1010 away from connecting post 2 104 is rotatably connected to connecting rod 2 1011. The end of connecting rod 2 1011 away from connecting rod 1 1010 is rotatably connected to panel 3 106.

[0041] In one embodiment of the present invention, due to the difference in linear velocity between the inner and outer rings during the operation of the rotary hearth furnace, it is difficult to uniformly distribute the material. If the rotary hearth furnace requires materials with a relatively high linear velocity for distribution, and when the amount of pellets is large, the pellets move evenly onto the chain conveyor 5 due to their own gravity, while when the amount of pellets is small, in order to coordinate with the smooth operation of subsequent devices, even if the pellets can be evenly transported into the rotary hearth furnace, the inclination angle of the third panel 106 is increased in a timely manner so that its descent speed is consistent with the descent speed of a large number of pellets. Then, the third panel 106 on the sorting component 10 folds 90°, the hydraulic rod 107 extends and drives the connecting column 103 to extend. During the elongation process, the connecting block 101 is pushed to move in the elongation direction. Since the connecting block 101 is an axisymmetric graphic block, the two sides of the connecting block 101 have the same shape. At the same time, the motor 3 108 starts and drives the connecting rod 1010 and connecting rod 2 1011 to rotate through the connecting column 2 104, thereby causing the panel 3 106 to rotate 90°. After the panel 3 106 has rotated, the side of the connecting block 101 opposite to the direction of movement moves to the arc groove 109, thereby preventing the pin 105 from being displaced and affecting the function of the device. Then, the material enters the chain conveyor 5 with a higher speed through the panel 3 106 during the descent process.

[0042] In one embodiment of the present invention, the fixing member 2 9 is kept at the same height as the chain conveyor 5, which is beneficial for the flipping and pushing component 7 to push the pellets on the chain conveyor 5.

[0043] As one embodiment of the present invention, fixing blocks 13 are fixedly connected to both sides of the upper end face of the chain plate conveyor 5 to prevent materials on the chain plate pusher 5 from falling off. Several rollers 14 are provided on the upper end face of the chain plate conveyor 5 to prevent materials from slipping off at an inclined angle.

[0044] In one embodiment of the present invention, the diameter of the arc groove 109 is equal to the diameter of the pin 105, so that when the pin 105 rotates into the arc groove 109, the arc groove 109 supports it, which is beneficial to the effective implementation of the sorting component 10, further beneficial to the sorting function of the entire device, and avoids pellet breakage.

[0045] As one embodiment of the present invention, the electric telescopic rod 73, when in its original state, will not affect the rotation of the turntable 70, thus preventing the fixed block 72, the electric telescopic rod 73, and the pushing block 74 from getting stuck and affecting the operation of the device when the turntable 70 rotates, even when the electric telescopic rod 73 is extended or in its original state.

[0046] In one embodiment of the present invention, the second fixed block 72 is arranged in an array with the center of the turntable 70 as the center. The number of the second fixed block 72, the electric telescopic rod 73 and the pushing block 74 are the same, so as to ensure that when the turntable 70 rotates, the pushing block 74 will always push the pellets so that they enter the rotary hearth furnace.

[0047] Specific working principle:

[0048] The hydraulic telescopic rod 24 extends, causing the panel block 23 to move in the same direction, such as... Figure 1-2 As shown, panel block 23 tilts upward to adjust the position of jetting machine 15 (jetting machine 15 is an existing product) and rotary hearth furnace. This reduces the risk of excessive impact from the jetting machine 15 being installed too high, which could increase the likelihood of pellet breakage and affect product quality. Long-term impact on the furnace bed would also reduce its service life. At the same time, it avoids the high operating temperature caused by the jetting machine 15 being installed too low near the furnace opening, which could affect the operation of the chain conveyor 5 and the jetting machine 15.

[0049] Two chain conveyors 5 are installed on panel 3. One chain conveyor 5 transports materials at a faster speed, while the other transports materials at a slower speed.

[0050] When the folding component 2 moves the device to a position that matches the discharge port of the rotary hearth furnace, such as Figure 1-5 As shown, the material moves onto the chain conveyor 5 through the feed inlet 11 of the device. Then, as the chain conveyor 5 moves forward, motor 71 drives the turntable 70 to rotate. The electric telescopic rod 73 on the turntable 70, closest to and parallel to the chain conveyor 5, extends, causing the pushing block 74 to extend, thus pushing the material on the chain conveyor 5 forward. While the electric telescopic rod 73 is pushing forward, the other electric telescopic rods 73 on the turntable 70 retract to their initial state to prevent jamming during rotation and affecting the normal operation of the device. Because the turntable 70 requires time to rotate, the electric telescopic rods 73 effectively distribute the material evenly during their movement, preventing material accumulation on one spot on the chain conveyor 5.

[0051] Furthermore, the bottom of the rotary hearth furnace is circular. Because the distance between each pellet and the center point of the rotary hearth furnace is different, the linear velocity at each position is also different. Therefore, it is necessary to evenly distribute loose materials such as granules and pellets on the feeding platform 16 (the velocity at the end of the feeding platform is the initial velocity), so that the speed at which they fall from the feeding platform 16 into the spraying machine 15 is different. Since the speed at which the material falls affects the distance at which the spraying machine 15 sprays the material, it affects the position of the material when it enters the rotary hearth furnace. By adjusting the speed at which the material falls into the spraying machine 15 and the speed at which the spraying machine 15 sprays the material, the speed of the material in the rotary hearth furnace can be made more consistent. This requires that the movement speeds on the two chain conveyors 5 be kept inconsistent, and the speed of the flipping and pushing device 7 needs to be consistent with the speed of the chain conveyor 5 on the same side. If the speeds of the two are not compatible, it will cause material to accumulate on the chain conveyor 5.

[0052] That is, the speeds of both are pre-adjusted. Because there is a certain difference in linear velocity between the inner and outer rings during the operation of the rotary hearth furnace, uniform material distribution is difficult. If the rotary hearth furnace requires materials with a higher linear velocity for distribution, and the material enters the slower conveyor belt of the chain conveyor 5 through panel 3 106, then panel 3 106 on the sorting component 10 needs to be folded 90°. Figure 6-7 As shown, the hydraulic rod 107 extends and drives the connecting column 103 to extend. During the extension of the connecting column 103, the connecting block 101 moves. One end of the connecting block 101 loosens the pin 105, while the other end fixes the pin 105, thus preventing the pin 105 from shifting during subsequent rotation. Then, the motor 3 108 starts and drives the connecting rod 1010 and the connecting rod 2 1011 to rotate through the connecting column 2 104, so that the panel 3 106 rotates around the unfixed pin 105. When the panel 3 106 rotates a certain angle, the motor 3 108 stops rotating, and the material enters the chain conveyor 5, which runs at a higher speed, through the panel 3 106.

[0053] When the amount of pellets is large, the pellets move evenly onto the chain conveyor 5 due to their own gravity. When the amount of pellets is small, in order to coordinate with the smooth operation of the subsequent equipment, even if the pellets can be evenly transported into the rotary hearth furnace, the tilt angle of panel three 106 is increased in a timely manner so that its descent speed is consistent with the descent speed of a large number of pellets. The tilt angle of panel three 106 on the sorting component 10 gradually increases and eventually approaches 90°. At this time, the hydraulic rod 107 remains stationary, and the diameter of the arc groove 109 is larger than the diameter of the pin 105. The pin 105 can rotate in the arc groove 109. At this time, the connecting block 101 also remains stationary to prevent the pin 105 from disengaging from the arc groove 109 during rotation, which would cause the equipment to malfunction. The motor three 108 continues to start and drives the connecting rod one 1010 and connecting rod two 1011 to continue rotating through the connecting column two 104, thereby gradually increasing the tilt angle of panel three 106 until it approaches 90°.

[0054] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
