Technical Field
[0001] This utility model relates to the technical field of pneumatic conveying pipeline accessories, and in particular to a new anti-clogging elbow for pneumatic coke powder conveying pipes. Background Technology
[0002] Coke powder is characterized by its small particle size, irregular shape, and high viscosity. During pneumatic conveying, when coke powder flows through bends in the airflow, complex physical interactions make these bends prone to clogging. On one hand, the abrupt change in airflow direction subjects the coke particles to strong centrifugal force, causing them to move closer to the inner wall of the bend. On the other hand, the presence of turbulent airflow further interferes with the normal flow of the coke powder, intensifying collisions and agglomeration between particles, making it easier for coke powder to accumulate on the inner wall of the bend. Over time, the accumulated coke powder gradually increases, the cross-sectional area of the pipeline decreases, and eventually, the pipeline becomes blocked.
[0003] In existing technologies, when coke powder flows through an elbow with the airflow, the sudden change in airflow direction causes the coke powder particles to accumulate on the inner wall of the elbow due to centrifugal force and airflow turbulence. Over time, the accumulated coke powder gradually increases, eventually leading to pipe blockage and severely affecting the continuity and stability of production.
[0004] To address the aforementioned problems, this utility model provides a novel anti-clogging elbow component for gas-carrying coke powder pipes. Utility Model Content
[0005] The purpose of this utility model is to solve the problem of easy clogging and poor anti-clogging effect of the elbow of the gas-transport coke powder pipe in the prior art, and to propose a new anti-clogging elbow component for the gas-transport coke powder pipe.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a new anti-clogging elbow component for gas-carrying coke powder pipe, comprising an elbow body, a pipeline guiding and air-inlet mechanism, and a connection stabilizing mechanism. There are two pipeline guiding and air-inlet mechanisms, which are threadedly connected to both ends of the elbow body. The connection stabilizing mechanism is snapped onto the outer surface of the pipeline guiding and air-inlet mechanism. The pipeline guiding and air-inlet mechanism includes a connecting pipe threadedly connected to the outer surface of the elbow body.
[0007] The pipeline air intake mechanism includes a rotating guide plate, an intake pipeline, and a gas flow control valve, with the gas flow control valve fixedly connected to the top of the intake pipeline.
[0008] The air intake pipe is fixedly connected to the top of the elbow body at the elbow position. A high-pressure air source connection port is fixedly connected to the top of the gas flow control valve. Flange connecting plates are fixedly connected to both sides of the connecting pipe. Sealing gaskets are snapped into both sides of the flange connecting plates. Fixing plates are symmetrically fixedly connected inside the connecting pipe.
[0009] Furthermore, a bearing is fixedly connected inside the fixed plate, and the outer surface of the bearing is fitted into the inside of the fixed plate. The bearing and the fixed plate are symmetrically arranged inside the connecting pipe.
[0010] Furthermore, the bearing has an internal rotating connection with a connecting rotating column, and the rotating guide plate is fixedly connected to the outer surface of the connecting rotating column at eight equal intervals.
[0011] Furthermore, limit bolts are threaded on both sides of the flange connecting plate, and limit nuts are threaded on the outer surface of the limit bolts. The sealing gaskets are snapped onto both ends of the elbow body by the limit bolts.
[0012] Furthermore, there are two connection stabilization mechanisms, including an upper ring that is snapped onto the outer surface of the connecting pipe, and limiters are threaded to both sides of the upper ring.
[0013] Furthermore, the bottom of the upper ring is threadedly connected to the lower ring via a limiting component. The inner walls of the upper and lower rings are fixedly connected to elastic damping springs, and the outer surface of the elastic damping springs is fixedly connected to a pipe clamping plate.
[0014] Furthermore, a fixed connecting plate is fixedly connected to the bottom of the upper ring, and wall connectors are threadedly connected to both sides of the fixed connecting plate. The wall connectors are symmetrically arranged on both sides of the fixed connecting plate.
[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a rotating guide plate, a gas flow control valve, and a high-pressure gas source connection port, the rotating guide plate can effectively guide the coke powder and airflow passing through the connecting pipe, promote the formation of a swirling airflow, enhance the carrying capacity of coke powder, and reduce the accumulation of coke powder on the inner wall of the connecting pipe and the elbow body. The gas flow control valve can precisely adjust the flow rate of high-pressure gas introduced from the high-pressure gas source connection port according to the actual conveying situation. When a tendency of coke powder accumulation is detected in the elbow, the gas flow rate can be increased, and the high-pressure gas can be used to purge the accumulated coke powder, so that it can be conveyed again with the airflow, effectively preventing blockage, greatly improving the anti-blockage capability of the gas-transported coke powder pipe, and ensuring the stable operation of the conveying system.
[0016] 2. In this utility model, the upper and lower rings are connected to the pipe clamping plate via the elastic damping spring, which can tightly clamp the connecting pipe. During the gas-transporting of coke powder, the elastic damping spring can effectively buffer the vibration of the pipe caused by the airflow impact and coke powder flow, reducing the damage to the pipe. The pipe clamping plate ensures that the connecting pipe remains stable in the installation position, avoiding poor conveying due to displacement. At the same time, the fixed connecting plate and the wall connector firmly fix the entire device to the support structure, further enhancing stability, thereby extending the service life of the pipe and the entire anti-clogging elbow, reducing maintenance costs, and improving production efficiency.

Detailed Implementation
[0019] Please see Figure 1-6This utility model provides a technical solution: a new anti-clogging elbow component for gas-carrying coke powder pipes, including an elbow body 1, a pipeline guiding and air-inlet mechanism 2, and a connecting and stabilizing mechanism 3. There are two pipeline guiding and air-inlet mechanisms 2, which are threadedly connected to both ends of the elbow body 1. The connecting and stabilizing mechanism 3 is snapped onto the outer surface of the pipeline guiding and air-inlet mechanism 2. The pipeline guiding and air-inlet mechanism 2 includes a connecting pipe 21 threadedly connected to the outer surface of the elbow body 1.
[0020] The following section will explain the specific setup and function of its pipeline air intake mechanism 2 and connection stabilization mechanism 3.
[0021] In this embodiment, the pipeline air intake mechanism 2 includes a rotating guide plate 22, an air intake pipeline 23, and a gas flow control valve 24, with the gas flow control valve 24 fixedly connected to the top of the air intake pipeline 23.
[0022] The intake pipe 23 is fixedly connected to the top of the elbow body 1 at the elbow position. The top of the gas flow control valve 24 is fixedly connected to the high-pressure gas source connection port 25. The two sides of the connecting pipe 21 are fixedly connected to the flange connecting plate 26. The two sides of the flange connecting plate 26 are clamped with sealing gaskets 27. The inside of the connecting pipe 21 is symmetrically fixedly connected to the fixing plate 28.
[0023] The effects achieved by the above components are as follows: the rotating guide plate 22 can guide the coke powder and airflow passing through the connecting pipe 21, promote the formation of a swirling airflow, enhance the carrying capacity of coke powder, and reduce the possibility of coke powder accumulating on the inner wall of the connecting pipe 21 and the elbow body 1. Under the precise control of the gas flow control valve 24, the high-pressure gas flow can be flexibly adjusted according to the coke powder accumulation in the elbow to effectively purge the coke powder that may accumulate and blow it back into the conveying airflow, ensuring the pipeline is unobstructed and greatly improving the anti-clogging performance of the gas-transported coke powder pipe. The sealing gasket 27 ensures the sealing of the connection, prevents coke powder and gas leakage, avoids environmental pollution, material waste and potential safety hazards caused by leakage, and maintains the pressure stability of the conveying system, which is conducive to the smooth conveying of coke powder.
[0024] Specifically, a bearing 29 is fixedly connected inside the fixing plate 28, and the outer surface of the bearing 29 is fitted into the inside of the fixing plate 28. The bearing 29 and the fixing plate 28 are symmetrically arranged inside the connecting pipe 21.
[0025] The effects achieved by the above components are as follows: the structural design enables the connecting rotating column 210 to rotate stably and flexibly under the support of the bearing 29. Under the impact of coke powder and airflow, the bearing 29 can effectively reduce the friction of the connecting rotating column 210 during rotation, ensuring that the rotating guide plate 22 can continuously and efficiently play its guiding role. Even under complex conveying conditions, it can ensure the stable operation of the rotating guide plate 22 and maintain a good anti-clogging effect. The symmetrically arranged bearing 29 and fixing plate 28 further enhance the stability and reliability of the structure, ensuring that the connecting rotating column 210 will not deviate or jam during rotation, thereby making the guiding effect of the rotating guide plate 22 on airflow and coke powder more uniform and stable.
[0026] Specifically, the bearing 29 is internally rotatably connected to a connecting rotating column 210, and the rotating guide plate 22 is fixedly connected to the outer surface of the connecting rotating column 210 at eight equal intervals.
[0027] The effects achieved by the above components are as follows: The eight-part rotating guide plate 22 is carefully designed to uniformly guide the coke powder and airflow passing through the connecting pipe 21. When the coke powder and airflow pass through the connecting pipe 21, the rotating guide plate 22 promotes the formation of a stable and efficient vortex, which on the one hand enhances the carrying capacity of coke powder, making it less likely to accumulate in the connecting pipe 21. On the other hand, the uniform guiding effect ensures that the coke powder is more evenly distributed in the connecting pipe 21, effectively reducing the possibility of local accumulation and greatly improving the conveying efficiency. The connecting rotating column 210 drives the rotating guide plate 22 to rotate under the support of the bearing 29, which can adapt to coke powder airflow with different flow rates and velocities, and adjust the guiding angle in time to cope with complex and ever-changing conveying conditions, further improving the anti-clogging effect.
[0028] Specifically, the flange connecting plate 26 is threaded with limit bolts 211 on both sides, and the outer surface of the limit bolts 211 is threaded with limit nuts 212. The sealing gaskets 27 are snapped onto both ends of the elbow body 1 by the limit bolts 211.
[0029] The aforementioned components achieve the following effects: by tightening the limiting bolts 211 and the limiting nuts 212, the flange connecting plate 26 can be tightly fixed to both ends of the elbow body 1, ensuring the firmness of the connection. The sealing gasket 27 is clamped between the flange connecting plate 26 and the elbow body 1, effectively filling the gap at the connection and preventing coke powder and gas from leaking from the connection. This connection method can not only withstand pressure fluctuations and mechanical vibrations during pneumatic conveying, but also ensure that the connection maintains good sealing and stability during long-term use, reducing maintenance costs and production interruption risks caused by leakage and loosening, and ensuring the reliable operation of the pneumatic coke powder conveying system.
[0030] Specifically, there are two connection stabilization mechanisms 3. The connection stabilization mechanism 3 includes an upper ring 31 that is snapped onto the outer surface of the connecting tube 21. Limiting members 32 are threadedly connected to both sides of the upper ring 31.
[0031] The effect achieved by the above components is as follows: the upper ring 31 is tightly engaged with the connecting pipe 21 by the limiting member 32, providing a solid installation foundation for the entire connection stabilization mechanism 3. During subsequent operation, it ensures that the connection stabilization mechanism 3 will not easily loosen or fall off, and can always play its stabilizing role. The limiting member 32 can be adjusted according to actual installation requirements, so that the upper ring 31 can be firmly fixed in a specific position of the connecting pipe 21, adapting to different installation environments and working conditions, and enhancing the versatility and adaptability of the device.
[0032] Specifically, the bottom of the upper ring 31 is threadedly connected to the lower ring 33 via the limiting member 32. The inner walls of the upper ring 31 and the lower ring 33 are fixedly connected to the elastic damping spring 34, and the outer surface of the elastic damping spring 34 is fixedly connected to the pipe clamping plate 35.
[0033] The effects achieved by the above components are as follows: the upper ring 31, the lower ring 33, the elastic damping spring 34, and the pipe clamping plate 35 cooperate with each other to ensure the stable installation of the connecting pipe 21 while effectively reducing the vibration and displacement generated during the conveying process. When pneumatically conveying coke powder, the pipe will vibrate due to the impact of airflow and the flow of coke powder. The elastic damping spring 34 can buffer the vibration, absorb some energy, and reduce the damage of vibration to the pipe. The pipe clamping plate 35 fits tightly against the connecting pipe 21 to prevent it from shaking, further improving the stability of the connecting pipe 21.
[0034] Specifically, a fixed connecting plate 36 is fixedly connected to the bottom of the upper ring 31, and wall connectors 37 are threadedly connected to both sides of the fixed connecting plate 36. The wall connectors 37 are symmetrically arranged on both sides of the fixed connecting plate 36.
[0035] The effects achieved by the above components are as follows: the entire anti-blocking elbow can be firmly installed on the wall or other supporting structure through the wall connector 37 and the fixed connecting plate 36. The symmetrically arranged wall connector 37 can evenly distribute the weight and force of the anti-blocking elbow, further enhancing its stability. In industrial production environments, complex airflow impacts and equipment vibrations may affect the installation stability of the anti-blocking elbow. This fixing method can ensure that the device remains stable under various working conditions, guarantee the reliable operation of the gas-transported coke powder system, and reduce the probability of poor conveying and failure caused by device displacement or shaking.
[0036] Working principle: During the gas transport of coke powder, coke powder and airflow enter the elbow body 1 through the connecting pipe 21. The rotating guide plate 22, driven by the connecting rotating column 210, guides the coke powder and airflow through the connecting pipe 21, causing the airflow to form a swirling flow, enhancing the carrying capacity of coke powder, and reducing the accumulation of coke powder on the inner wall of the connecting pipe 21 and the elbow body 1.
[0037] When coke powder accumulates in the elbow, the flow rate of high-pressure gas introduced through the high-pressure gas source connection port 25 can be adjusted by the gas flow control valve 24. The high-pressure gas is used to purge the accumulated coke powder and allow it to be transported again with the airflow.
[0038] The upper ring 31 and lower ring 33 in the connecting stabilizing mechanism 3 tightly clamp the connecting pipe 21 with the pipe clamping plate 35 through the elastic damping spring 34. The elastic damping spring 34 buffers the vibration of the pipe caused by airflow impact and coke powder flow, and the pipe clamping plate 35 ensures that the connecting pipe 21 remains stable in the installation position.
[0039] The fixed connecting plate 36 and the wall connector 37 firmly fix the entire device to the supporting structure, further enhancing stability, thereby achieving an efficient and stable gas-transport coke powder process, effectively solving the problems of easy clogging and poor anti-clogging effect of the bend in the gas-transport coke powder pipe in the existing technology.
