Description

Technical Field

[0001] This invention relates to the field of lime calcination equipment technology, specifically to a material uniform distribution device for a lime calcination kiln. Background Technology

[0002] Quicklime is an indispensable industrial raw material in industrial production. A lime kiln is a kiln used to calcine limestone at high temperatures to produce quicklime, and it plays an important role in the quicklime manufacturing process. The rotary distributor is an important piece of mechanical equipment in the lime kiln, which mainly distributes coal and limestone evenly on the kiln opening section of the lime kiln, so that the limestone is fully calcined and the quicklime output is increased.

[0003] Traditional feeding devices often use fixed-angle feeding plates or fixed-point feeding structures, which cannot adjust the feeding angle in real time according to the amount of material per unit time. This can easily lead to localized material accumulation and uneven material layer thickness in the kiln, resulting in uneven burning, underburning, and overburning, thus reducing the qualified rate of lime products and calcination efficiency. At the same time, baffles are used to prevent material from hitting the kiln wall. However, existing baffles are mostly fixed in opening or independently driven, and cannot adjust the opening and closing angle synchronously with the inclination angle of the feeding plate and the amount of material. When the amount of material is large, it is easy to cause poor material feeding and material splashing that impacts the kiln wall. When the amount of material is small, it is easy to cause material deviation and scraping of the kiln wall. Long-term operation will accelerate the wear of refractory materials, shorten the kiln overhaul cycle, and increase maintenance costs.

[0004] To address the aforementioned shortcomings, this application provides a uniform material distribution device for lime calcining kilns that integrates quantitative material feeding adjustment, gravity-driven self-tilting material distribution, adaptive linkage of baffle plates, parallelogram posture constraint, tension spring torque self-balancing, and adjustable preload. This device solves the pain points of traditional technologies from the perspectives of structural linkage and mechanical coordination. Summary of the Invention

[0005] The purpose of this invention is to provide a material uniform distribution device for a lime calcination kiln to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a material uniform distribution device for a lime calcination kiln, comprising a gravity self-tilting component, the gravity self-tilting component comprising a connecting plate, mounting ears fixedly installed on both sides of the bottom end of the connecting plate, and a back plate fixedly installed at the end of the connecting plate, trunnions symmetrically fixedly installed on both sides of the back plate, and a material distribution plate rotatably installed inside the trunnions, a discharge port provided at the bottom end of the material distribution plate cavity, and hanging plates fixedly installed on both sides of the bottom end of the material distribution plate, a tension spring connected to the outer periphery of the hanging plate through a lifting ring, and an adjusting handle connected to the end of the tension spring away from the hanging plate, the adjusting handle being threadedly connected to one end of a mounting sleeve, and the other end of the mounting sleeve being rotatably connected to the mounting ears.

[0007] Furthermore, the tension spring provides an elastic preload, which, when the incoming material causes the fabric plate to rotate around the trunnion, cancels out the gravitational torque generated by the incoming material by the elastic torque generated by the tension spring, maintaining the fabric plate's gravity self-balance at any position throughout the entire swing range.

[0008] Furthermore, a linkage adjustment assembly is installed on both sides of the fabric plate. The linkage adjustment assembly includes mounting rods installed on both sides of the front end of the fabric plate. A moving sprocket is coaxially installed on the inner side of the mounting rod, and a chain is engaged on the outer periphery of the moving sprocket.

[0009] Furthermore, the linkage adjustment component also includes a fixed sprocket engaged with the other end of the chain away from the moving sprocket. The fixed sprocket is fixedly installed on the inner wall of the trunnion, and the inner diameter of the hole in the fixed sprocket is larger than the outer diameter of the rotating shafts on both sides of the rear end of the fabric plate.

[0010] Furthermore, the linkage adjustment component also includes a connecting arm coaxially mounted on the outside of the mounting rod, with baffle plates fixedly connected to the ends of the connecting arms on both sides. The baffle plates and the material distribution plate work together to prevent the incoming material from hitting the lime kiln wall during the material distribution process.

[0011] Furthermore, the fabric plate, as the core material carrier, forms a parallelogram mechanism with the back plate and chain to ensure that the bearing section always maintains a stable posture when the fabric plate rotates. When the fabric plate rotates due to changes in the quality of the incoming material, the chain pulls the left moving sprocket to rotate in the opposite direction, thereby causing the baffle plate, which is coaxial with the left moving sprocket, to rotate in the opposite direction synchronously.

[0012] Furthermore, the connecting plate is fixedly installed on the bottom outer periphery of the rotating conveyor cylinder at one end away from the back plate, and a large toothed ring is coaxially fixed on the outer periphery of the middle part of the rotating conveyor cylinder, and a sealing bushing is installed on the top of the rotating conveyor cylinder.

[0013] Furthermore, the rotary conveyor cylinder is rotatably installed in the middle of the kiln roof plate, and a reduction motor is fixedly installed on the side of the kiln roof plate. A small gear is fixedly connected to the rotating end of the reduction motor, and the small gear rotates and drives the rotary conveyor cylinder through meshing with a large gear ring.

[0014] Furthermore, a material feeding adjustment assembly is fixedly installed on the kiln top plate. The material feeding adjustment assembly includes a hopper connected to the top opening of the rotary conveyor cylinder. The hopper is bolted to the kiln top plate by a bracket, and the bottom opening of the hopper is sealed to the top opening of the rotary conveyor cylinder by a sealing bushing.

[0015] Furthermore, the material receiving adjustment assembly also includes a stepper motor fixedly installed on the outer wall of the hopper. A rotary valve is fixedly connected to the rotating end of the stepper motor, and partition plates are fixedly arranged concentrically around the outer periphery of the rotary valve. The gap between adjacent partition plates is used to receive the incoming material and to transfer the material to the rotary conveyor cylinder by rotating the rotary valve.

[0016] This invention provides a material uniform distribution device for a lime calcination kiln, which has the following beneficial effects; 1. In this device, the change in the amount of material supplied directly drives the adjustment of the tilt angle of the feeding plate. When the amount of material supplied is too large, the feeding plate increases the tilt angle to accelerate the falling and spreading speed of the material and avoid local material accumulation in the kiln. When the amount of material supplied is too small, the feeding plate decreases the tilt angle to slow down the falling speed of the material and prevent the material from being sparsely distributed. Through the real-time linkage between the amount of material supplied and the feeding angle, the feeding plate can evenly spread the material in the lime kiln to form a material layer of uniform thickness and distribution, ensuring the uniformity of the calcination reaction from the source.

[0017] 2. In this device, the feeding plate serves as the bearing side, the back plate as the fixing side, and the chain as the flexible connecting rod side. The parallelogram mechanism formed by these three components strictly constrains the rotation trajectory of the feeding plate. The tension spring is connected to the feeding plate through the hanging plate, providing initial elastic preload. When the feeding plate rotates due to incoming material, the gravitational torque generated by the material and the elastic force generated by the tension spring are coupled in opposite directions to cancel each other out, ensuring that the feeding plate maintains gravity self-balance at any position within the entire swing range. The initial tension of the tension spring can be changed by rotating the adjustment handle, thereby adjusting its elastic preload. This adjustment action forms a working condition adaptation linkage with the swing requirements of the feeding plate. Through the linkage adaptation of the tension spring preload by the adjustment handle, this device can quickly switch to adapt to production conditions with different incoming material amounts and different material characteristics without redesigning equipment components for different kiln types or production capacities. This linkage adaptation capability greatly improves the reusability of the equipment and the flexibility of the production line, reducing the equipment investment and modification costs for enterprises, especially suitable for multi-variety, small-batch lime production scenarios.

[0018] 3. In this device, the baffle plate opens and closes adaptively according to the amount of material supplied. When the amount of material supplied is large, the baffle plate opens at a large angle, which not only ensures the material is discharged quickly and smoothly, avoiding jamming of the material distribution plate, but also buffers the impact force of the falling material through the guiding effect of the baffle plate, reducing the direct impact of the material on the kiln wall. When the amount of material supplied is small, the baffle plate closes at a small angle, constraining the trajectory of the falling material and further reducing the probability of the material splashing to the edge of the kiln wall. Through the linkage protection of the material distribution plate and the baffle plate, the damage to the refractory material of the kiln wall and the air leakage of the kiln body can be greatly reduced, the overhaul cycle and overall service life of the lime kiln can be extended, and the equipment maintenance and replacement costs can be reduced.

[0021] 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. Please see Figures 1 to 7 This invention provides a technical solution: a material uniform distribution device for a lime calcination kiln, comprising a gravity self-tilting component 1. The gravity self-tilting component 1 includes a connecting plate 101, mounting ears 102 fixedly installed on both sides of the bottom end of the connecting plate 101, and a back plate 103 fixedly installed at the end of the connecting plate 101. Trunnions 104 are symmetrically fixedly installed on both sides of the back plate 103, and a material distribution plate 105 is rotatably installed inside the trunnions 104. A discharge port 106 is provided at the bottom end of the cavity of the material distribution plate 105, and hanging plates 10 are fixedly installed on both sides of the bottom end of the material distribution plate 105. 7. A tension spring 108 is connected to the outer periphery of the hanging plate 107 via a lifting ring, and an adjusting handle 109 is connected to the end of the tension spring 108 away from the hanging plate 107. The adjusting handle 109 is threaded to one end of the mounting sleeve 110, and the other end of the mounting sleeve 110 is rotatably connected to the mounting ear 102. The tension spring 108 provides elastic preload. When the incoming material causes the fabric plate 105 to rotate around the trunnion 104, the gravitational torque generated by the incoming material is offset by the elastic torque generated by the tension spring 108, maintaining the self-balance of gravity of the fabric plate 105 at any position within the entire swing range. The specific operation is as follows: the fabric plate 105 serves as the bearing side, the back plate 103 as the fixing side, and the chain 203 as the flexible connecting rod side. The parallelogram mechanism formed by these three components strictly constrains the rotation trajectory of the fabric plate 105. Regardless of the angle to which the fabric plate 105 rotates around the trunnion 104 due to changes in the amount of incoming material, its bearing section always maintains a stable posture parallel to the back plate 103, preventing the fabric plate 105 from swaying, tilting, or shifting its posture. This ensures the accuracy of the fabric application from a mechanical structure perspective. The tension spring 108 is connected to the fabric plate 105 through the hanging plate 107, providing initial elastic preload. When the incoming material causes the fabric plate 105 to rotate, the gravitational torque generated by the material and the elastic torque generated by the tension spring 108 are coupled in opposite directions to cancel each other out. That is, the greater the gravitational torque, the greater the tension of the tension spring 108, and the greater the elastic torque. The pressure increases until the two reach equilibrium, so that the feeding plate 105 maintains gravity self-balance at any position within the entire swing range. In this application, the adjusting handle 109 is threadedly connected to the mounting sleeve 110. Rotating the adjusting handle 109 can change the initial tension of the tension spring 108, thereby adjusting its elastic preload. This adjustment action forms a working condition adaptation linkage with the swing requirements of the feeding plate 105. Through the linkage adaptation of the adjusting handle 109 to the preload of the tension spring 108, this device can quickly switch to adapt to different material quantities and different material characteristics in production conditions. There is no need to redesign equipment components for different kiln types or production capacities. This linkage adaptation capability greatly improves the equipment reuse rate and the flexibility of the production line, and reduces the equipment investment and transformation costs of enterprises, especially suitable for multi-variety, small-batch lime production scenarios. Please see Figures 4 to 6 The fabric plate 105 is equipped with a linkage adjustment assembly 2 on both sides. The linkage adjustment assembly 2 includes mounting rods 201 mounted on both sides of the front end of the fabric plate 105. A moving sprocket 202 is coaxially mounted on the inner side of the mounting rod 201, and a chain 203 is engaged with the outer circumference of the moving sprocket 202. The linkage adjustment assembly 2 also includes a fixed sprocket 204 engaged with the other end of the chain 203 away from the moving sprocket 202. The fixed sprocket 204 is fixedly mounted on the inner wall of the trunnion 104, and the inner diameter of the hole of the fixed sprocket 204 is larger than the outer diameter of the rotating shafts on both sides of the rear end of the fabric plate 105. The linkage adjustment assembly 2 also includes a mounting rod 201 coaxially mounted on the outer side of the mounting rod 201. The connecting arm 205 on both sides is fixedly connected to the end of the connecting arm 205 with a baffle plate 206. The baffle plate 206 and the material distribution plate 105 work together to prevent the incoming material from hitting the wall of the lime kiln during the material distribution process. The material distribution plate 105, as the core material bearing component, forms a parallelogram mechanism with the back plate 103 and the chain 203. This mechanism is used to ensure that the bearing section always maintains a stable posture when the material distribution plate 105 rotates. When the material distribution plate 105 rotates due to changes in the quality of the incoming material, the chain 203 pulls the left moving sprocket 202 to rotate in the opposite direction, thereby causing the baffle plate 206, which is coaxial with the left moving sprocket 202, to rotate in the opposite direction synchronously. The specific operation is as follows: When the fabric plate 105 rotates around the trunnion 104 due to changes in the incoming material quality, the mounting rod 201 at the front end of the fabric plate 105 rotates synchronously with the fabric plate 105, causing the moving sprocket 202 to rotate in the opposite direction. The rotation of the moving sprocket 202 is transmitted to the fixed sprocket 204 through the meshing transmission of the chain 203. Then, through the reverse pull of the chain 203, the connecting arm 205 is driven to swing in the opposite direction to the rotation of the fabric plate 105, ultimately driving the baffle plate 206 to open and close synchronously. This makes the opening angle of the baffle plate 206 directly tied to the rotation amplitude of the fabric plate 105. That is, the larger the incoming material quantity, the larger the rotation amplitude of the fabric plate 105, the larger the rotation angle of the moving sprocket 202, and the larger the opening angle of the baffle plate 206. Conversely, the smaller the incoming material quantity, the smaller the opening angle of the baffle plate 206. The opening angles of the six plates decrease synchronously, forming a precise adaptive linkage between the rotation amplitude of the material distribution plate 105 and the opening degree of the baffle plate 206. In this device, the baffle plate 206 opens and closes adaptively with the amount of material coming in. When the amount of material coming in is large, the baffle plate 206 opens at a large angle, which not only ensures that the material is discharged quickly and smoothly and avoids jamming of the material distribution plate 105, but also buffers the impact force of the falling material through the guiding effect of the baffle plate 206, reducing the direct impact of the material on the kiln wall. When the amount of material coming in is small, the baffle plate 206 closes at a small angle, constraining the falling trajectory of the material and further reducing the probability of the material splashing to the edge of the kiln wall. Through the linkage protection of the material distribution plate 105 and the baffle plate 206, the damage to the refractory material of the kiln wall and the air leakage of the kiln body can be greatly reduced, the overhaul cycle and overall service life of the lime kiln can be extended, and the equipment maintenance and replacement costs can be reduced. Please see Figures 1 to 2 The connecting plate 101 is fixedly installed on the bottom outer periphery of the rotary conveyor cylinder 3 at one end away from the back plate 103, and a large gear ring 4 is coaxially fixed on the outer periphery of the middle part of the rotary conveyor cylinder 3. A sealing bushing 5 is installed on the top of the rotary conveyor cylinder 3. The rotary conveyor cylinder 3 is rotatably installed on the middle part of the kiln top plate 6, and a reduction motor 7 is fixedly installed on the side of the kiln top plate 6. A small gear 8 is fixedly connected to the rotating end of the reduction motor 7, and the small gear 8 rotates and drives the rotary conveyor cylinder 3 through meshing with the large gear ring 4. The specific operation is as follows: the reduction motor 7 on the side of the kiln top plate 6 is driven by the small gear 8 meshing with the large gear ring 4 of the rotating conveyor cylinder 3, which drives the rotating conveyor cylinder 3 and the bottom material distribution assembly to rotate circumferentially, so that the material is evenly distributed in the lime kiln for calcination. Please see Figures 3 to 4A material feeding adjustment assembly 9 is fixedly installed on the kiln top plate 6. The material feeding adjustment assembly 9 includes a hopper 901 connected to the top opening of the rotary conveyor 3. The hopper 901 is bolted to the kiln top plate 6 by a bracket 902, and the bottom opening of the hopper 901 is sealed to the top opening of the rotary conveyor 3 by a sealing bushing 5. The material feeding adjustment assembly 9 also includes a stepper motor 903 fixedly installed on the outer wall of the hopper 901. A rotary valve 904 is fixedly connected to the rotating end of the stepper motor 903, and partition plates 905 are fixedly arranged concentrically on the outer periphery of the rotary valve 904. The gap between adjacent partition plates 905 is used to receive the material and to transfer the material to the rotary conveyor 3 by the rotation of the rotary valve 904. The specific operation is as follows: The uniformly mixed limestone and fuel are added from the top of the hopper 901. The stepper motor 903 drives the rotary valve 904 to rotate at a constant speed. The material is clamped in the gap between adjacent partition plates 905, forming a quantitative material segment. With the rotation of the rotary valve 904, it is stably conveyed to the rotary conveyor cylinder 3, and finally falls into the bearing cavity of the distribution plate 105. By adjusting the speed of the stepper motor 903, the material conveying amount per unit time can be directly controlled, achieving stepless and precise adjustment of the feeding amount. When the mass of the material carried by the distribution plate 105 changes, the gravity of the material will generate a driving torque, pushing the distribution plate 105 to rotate and tilt around the trunnion 104. The greater the mass of the material, the greater the rotational tilt amplitude of the distribution plate 105. The smaller the mass, the smaller the tilt angle. During this process, the tilt angle of the feeding plate 105 forms a positively correlated adaptive coupling with the material feed rate, no longer relying on manual or additional passive adjustment. In this device, the change in the material feed rate directly drives the adjustment of the tilt angle of the feeding plate 105. When the material feed rate is too large, the feeding plate 105 increases the tilt angle to accelerate the material falling and spreading speed, avoiding local material accumulation in the kiln. When the material feed rate is too small, the feeding plate 105 decreases the tilt angle to slow down the material falling rate and prevent sparse material distribution. Through the real-time linkage between the material feed rate and the feeding angle, the feeding plate 105 can evenly spread the material in the lime kiln to form a uniformly thick and evenly distributed material layer, ensuring the uniformity of the calcination reaction from the source.

[0022] In summary, when using the material uniform distribution device of this lime calcining kiln: First, the uniformly mixed limestone and fuel are added from the top of the hopper 901. The stepper motor 903 drives the rotary valve 904 to rotate at a constant speed. The material is locked in the gap between the adjacent partition plates 905 to form a quantitative material segment. As the rotary valve 904 rotates, it is stably conveyed to the rotary conveyor cylinder 3 and finally falls into the bearing cavity of the material distribution plate 105. By adjusting the speed of the stepper motor 903, the material conveying amount per unit time can be directly controlled, realizing stepless and precise adjustment of the feeding amount. Secondly, the reduction motor 7 on the side of the kiln top plate 6 is driven by the small gear 8 meshing with the large gear ring 4 of the rotating conveyor cylinder 3, which drives the rotating conveyor cylinder 3 and the bottom material distribution assembly to rotate circumferentially, so that the material is evenly distributed in the lime kiln for calcination. Then, when the mass of the material carried by the feeding plate 105 changes, the gravity of the material will form a driving torque, pushing the feeding plate 105 to rotate and tilt around the trunnion 104. The greater the mass of the material, the greater the rotational tilt of the feeding plate 105; the smaller the mass of the material, the smaller the tilt. In this process, the tilt angle of the feeding plate 105 and the amount of material are positively correlated and adaptively coupled, no longer relying on manual or additional passive adjustment. In this device, the change in the amount of material directly drives the adjustment of the tilt angle of the feeding plate 105. When the amount of material is too large, the feeding plate 105 increases the tilt angle to accelerate the falling and spreading speed of the material and avoid local material accumulation in the kiln. When the amount of material is too small, the feeding plate 105 decreases the tilt angle to slow down the falling rate of the material and prevent the material from being sparsely distributed. Through the real-time linkage between the amount of material and the feeding angle, the feeding plate 105 can spread the material evenly in the lime kiln to form a material layer of uniform thickness and distribution, ensuring the uniformity of the calcination reaction from the source. Furthermore, the fabric plate 105 serves as the bearing side, the back plate 103 as the fixing side, and the chain 203 as the flexible connecting rod side. The parallelogram mechanism formed by these three components strictly constrains the rotation trajectory of the fabric plate 105. Regardless of the angle to which the fabric plate 105 rotates around the trunnion 104 due to changes in the amount of material received, its bearing section always maintains a stable posture parallel to the back plate 103, preventing the fabric plate 105 from swaying, tilting, or shifting its posture. This ensures the accuracy of the fabric application from a mechanical structural perspective. The tension spring 108 is connected to the fabric plate 105 through the hanging plate 107, providing initial elastic preload. When the material arrives and causes the fabric plate 105 to rotate, the gravitational torque generated by the material and the elastic torque generated by the tension spring 108 are coupled in opposite directions to cancel each other out. That is, the greater the gravitational torque, the greater the tension of the tension spring 108, and the greater the elastic torque. The adjustment handle 109 is threadedly connected to the mounting sleeve 110. Rotating the adjustment handle 109 can change the initial tension of the tension spring 108, thereby adjusting its elastic preload. This adjustment action and the swing requirements of the fabric plate 105 form a working condition adaptation linkage. Through the linkage adaptation of the adjustment handle 109 to the preload of the tension spring 108, this device can quickly switch to adapt to different material quantities and different material characteristics in production conditions. There is no need to redesign equipment components for different kiln types or production capacities. This linkage adaptation capability greatly improves the reusability of equipment and the flexibility of the production line, and reduces the equipment investment and transformation costs of enterprises, especially suitable for multi-variety, small-batch lime production scenarios. Finally, when the fabric plate 105 rotates around the trunnion 104 due to changes in the incoming material quality, the mounting rod 201 at the front end of the fabric plate 105 rotates synchronously with the fabric plate 105, causing the moving sprocket 202 to rotate in the opposite direction. The rotation of the moving sprocket 202 is transmitted to the fixed sprocket 204 through the meshing transmission of the chain 203. Then, through the reverse pull of the chain 203, the connecting arm 205 is driven to swing in the opposite direction to the rotation of the fabric plate 105, ultimately driving the baffle plate 206 to open and close synchronously. This makes the opening angle of the baffle plate 206 directly tied to the rotation amplitude of the fabric plate 105. That is, the greater the incoming material quantity, the greater the rotation amplitude of the fabric plate 105, the greater the rotation angle of the moving sprocket 202, and the greater the opening angle of the baffle plate 206. Conversely, the smaller the incoming material quantity, the smaller the opening angle of the baffle plate 206. The opening angle decreases synchronously, forming a precise adaptive linkage between the rotation amplitude of the material distribution plate 105 and the opening degree of the baffle plate 206. In this device, the baffle plate 206 opens and closes adaptively according to the amount of material coming in. When the amount of material coming in is large, the baffle plate 206 opens at a large angle, which not only ensures that the material is discharged quickly and smoothly and avoids jamming of the material distribution plate 105, but also buffers the impact force of the falling material through the guiding effect of the baffle plate 206, reducing the direct impact of the material on the kiln wall. When the amount of material coming in is small, the baffle plate 206 closes at a small angle, constraining the falling trajectory of the material and further reducing the probability of the material splashing to the edge of the kiln wall. Through the linkage protection of the material distribution plate 105 and the baffle plate 206, the damage to the refractory material of the kiln wall and the air leakage of the kiln body can be greatly reduced, the overhaul cycle and overall service life of the lime kiln can be extended, and the equipment maintenance and replacement costs can be reduced.
