Description

Technical Field

[0001] This utility model belongs to the technical field of cement production equipment, specifically a rotor scale flow stabilizing feed device for cement clinker production lines. Background Technology

[0002] In the cement production process, the stable and precise feeding of powdery materials such as raw meal and pulverized coal is a key step in ensuring the quality of cement clinker and reducing energy consumption. Rotary scales, as precision continuous weighing and feeding equipment, play a central role in this process.

[0003] However, in practical applications, the material in the upstream silo often experiences unstable and collapsed feeding, leading to significant fluctuations in the material flow rate entering the rotor scale. This unstable incoming material impacts the rotor scale's measuring chamber, causing violent fluctuations in the weighing sensor signal, severely affecting measurement accuracy and control stability. Ultimately, this results in inaccurate raw material proportioning or unstable coal feeding at the kiln head, impacting clinker burning quality and increasing energy consumption. Utility Model Content

[0004] This invention provides a rotor scale flow stabilizing feeding device for cement clinker production lines to address the deficiencies in existing technologies.

[0005] This utility model is achieved through the following technical solution: A rotor scale steady-flow feeding device for a cement clinker production line includes a silo, a conveying auger, and a buffer tank. The conveying auger is arranged horizontally with its inlet facing upward and communicating with the outlet of the silo. The outlet of the conveying auger faces downward and communicates with the inlet of the buffer tank. The outlet of the buffer tank faces downward and communicates with the inlet of the rotor scale.

[0006] When this application is in use, if the material in the hopper collapses, it will quickly accumulate on the upper part of the conveying auger. Since the conveying auger does not produce excessive material during the conveying process, it can ensure that the material enters the buffer tank relatively evenly and then enters the rotor scale through the buffer tank. Since the buffer tank is a transition section, there will be no accumulation phenomenon, and thus no collapse phenomenon will occur. This effectively avoids the phenomenon of sudden increase in material entering the rotor scale, ensuring measurement accuracy and stability.

[0007] Preferably, several guide plates are fixedly installed inside the buffer tank from top to bottom. The guide plates are staggered and fixed on the inner walls of both sides of the buffer tank with their inner ends tilted downwards. The guide plates can guide the flow and further prevent the buffer tank from becoming blocked, thereby reducing the probability of collapse.

[0008] Preferably, a material dispersing paddle is provided at the top of the buffer tank. The material dispersing paddle is mounted on a horizontal rotating shaft, which is driven by a drive mechanism to rotate along its axis. The rotation of the material dispersing paddle can disperse the material and further reduce the clogging of the buffer tank.

[0009] Preferably, the drive mechanism includes a rotating rod, the inner end of which passes through the housing of the conveying auger and is coaxially and fixedly connected to the rotating shaft of the conveying auger. A drive wheel is fixedly sleeved on the outer end of the rotating rod. The rotating shaft passes through the buffer tank and is rotatably connected to the buffer tank via a bearing at the exit point. A driven wheel is fixedly sleeved on the outer end of the rotating shaft. The drive wheel and the driven wheel are driven by a transmission belt. When the conveying auger is working, the rotating shaft of the conveying auger drives the rotating rod to rotate, the rotating rod drives the drive wheel to rotate, and the drive wheel drives the driven wheel to rotate via the transmission belt, thereby realizing the rotation of the rotating shaft and driving the bulk material slurry to rotate.

[0010] Preferably, a vibration motor is fixedly installed on the outer wall of the silo, which can drive the silo to vibrate, prevent the material in the silo from caking, and ensure its smooth discharge.

[0011] The beneficial effects of this utility model are as follows: The use of this application can utilize the conveying auger and buffer tank to still smoothly transport the material into the rotor scale when the material in the silo collapses, thereby effectively avoiding the phenomenon of a sudden increase in the amount of material entering the rotor scale and ensuring measurement accuracy and stability.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] A rotor scale flow stabilizing feeder for a cement clinker production line, such as Figure 1 As shown, it includes a hopper 1, a conveying auger 2, and a buffer tank 3. The conveying auger 2 is arranged horizontally with its inlet facing upward and communicating with the outlet of the hopper 1. The outlet of the conveying auger 2 is connected downward and communicating with the inlet of the buffer tank 3. The outlet of the buffer tank 3 is connected downward and communicating with the inlet of the rotor scale. A vibration motor is fixedly installed on the outer wall of the hopper 1.

[0017] When this application is in use, if the material in the hopper 1 collapses, it will quickly accumulate on the upper part of the conveying auger 2. Since the conveying auger 2 does not have excessive material during the conveying process, it can ensure that the material enters the buffer tank 3 relatively evenly and then enters the rotor scale through the buffer tank 3. Since the buffer tank 3 is a transition section, there will be no accumulation phenomenon, and thus no collapse phenomenon will occur. This effectively avoids the phenomenon of sudden increase in material entering the rotor scale, ensuring measurement accuracy and stability. The outer wall of the hopper 1 is fixedly equipped with a vibration motor, which can drive the hopper 1 to vibrate, preventing the material in the hopper 1 from caking and ensuring its smooth discharge.

[0018] Several guide plates 4 are fixedly installed inside the buffer tank 3 from top to bottom. The guide plates 4 are staggered and fixed on the inner walls of both sides of the buffer tank 3 with their inner ends tilted downward. The guide plates 4 can play a role in guiding the flow, further preventing the buffer tank 3 from becoming blocked, thereby reducing the probability of collapse.

[0019] The upper part of the buffer tank 3 is provided with a material dispersing paddle 5, which is mounted on a horizontal rotating shaft. The rotating shaft is driven by a drive mechanism to rotate along its axis. The rotation of the material dispersing paddle 5 can disperse the material and further reduce the blockage of the buffer tank 3.

[0020] The drive mechanism includes a rotating rod 9. The inner end of the rotating rod 9 passes through the outer shell of the conveying auger 2 and is coaxially and fixedly connected to the rotating shaft of the conveying auger 2. A drive wheel 6 is fixedly sleeved on the outer end of the rotating rod 9. The rotating shaft passes through the buffer tank 3 and is rotatably connected to the buffer tank 3 at the exit point via a bearing. A driven wheel 7 is fixedly sleeved on the outer end of the rotating shaft. The drive wheel 6 and the driven wheel 7 are driven by a transmission belt 8. When the conveying auger 2 is working, the rotating shaft of the conveying auger 2 drives the rotating rod 9 to rotate, the rotating rod 9 drives the drive wheel 6 to rotate, and the drive wheel 6 drives the driven wheel 7 to rotate via the transmission belt 8, thereby realizing the rotation of the rotating shaft and driving the bulk material paddle 5 to rotate.

[0021] The use of this application enables the conveying auger 2 and buffer tank 3 to smoothly transport materials into the rotor scale even when materials collapse in the hopper 1, thereby effectively preventing a sudden increase in the amount of material entering the rotor scale and ensuring measurement accuracy and stability.
