Description

Technical Field

[0001] The utility model relates to the technical field of flue gas treatment, in particular to a fly ash conveying flue gas treatment system. Background Technique

[0002] The fly ash conveying flue gas treatment system is a comprehensive system involving fly ash conveying and flue gas purification. It is mainly used to treat fly ash generated in places such as thermal power plants, and conducts flue gas treatment during the conveying process to ensure the effective treatment of fly ash and the clean discharge of flue gas. In the fly ash conveying part, usually based on the principle of pneumatic conveying, through components such as closed pipelines, senders, feed valves, and exhaust valves, the fly ash is conveyed from equipment such as reaction towers and bag filters to the fly ash storage bin. This conveying method can reduce the diffusion of fly ash in the air and achieve fully sealed and pollution-free conveying. The flue gas treatment part mainly focuses on the purification and emission control of flue gas. This usually includes using equipment such as activated carbon addition devices and dust collectors to remove harmful substances and particulate matter in the flue gas, so that the discharged flue gas meets environmental protection standards.

[0003] The following disadvantages exist in the prior art: The humidity of the fly ash is relatively high, and it is easy to agglomerate and adhere to the conveying pipeline, causing pipeline blockage and making it difficult to convey the fly ash. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fly ash conveying flue gas treatment system to solve the problem that the humidity of the fly ash is relatively high, it is easy to agglomerate and adhere to the conveying pipeline, causing pipeline blockage and making it difficult to convey the fly ash.

[0005] To achieve the above-mentioned utility model purpose, the utility model adopts the following technical scheme: A fly ash conveying flue gas treatment system includes a connecting frame, the connecting frame is fixedly installed on the top surface of the base, a dust storage tank is fixedly installed inside the connecting frame, an ash discharge pipe is fixedly installed inside the dust storage tank, one end of the ash discharge pipe is fixedly installed with a conveying pipe, an installation block is fixedly installed on the top surface of the base, a stepping motor is fixedly installed on the top surface of the installation block, a top block is fixedly installed at one end of the rotating shaft of the stepping motor, an installation frame is fixed on the top surface of the connecting frame, a rotating column is fixedly installed inside the installation frame, and a rotating rod is rotatably inserted on the outer wall of the rotating column.

[0006] Preferably, a sliding rod is fixedly installed inside the rotating rod. A spring is slidably inserted on the outer wall of the sliding rod. A sliding block is slidably inserted on the outer wall of the sliding rod. One end of the spring is fixedly installed on the inner top surface of the rotating rod, and the other end of the spring is fixedly installed on the top surface of the sliding block. A moving block is rotatably clamped on the outer wall of the sliding block. A fixed frame is fixedly installed on one side of the mounting frame. A moving rod is fixedly installed on one side of the fixed frame. The moving block is movably inserted on the outer wall of the moving rod.

[0007] Preferably, a limiting block is fixedly installed at one end of the moving rod.

[0008] Preferably, a rubber pad is fixedly installed on one side of the rotating rod.

[0009] Preferably, a rotating rod is fixedly installed inside the conveying pipe, and a rotating stirring blade is inserted on the outer wall of the rotating rod.

[0010] Preferably, two limiting rings are arranged on both sides of the rotating stirring blade, and the limiting rings are fixedly installed on the outer wall of the rotating rod.

[0011] Compared with the prior art, a fly ash conveying flue gas treatment system adopting the above technical scheme has the following beneficial effects:

[0012] First, during use, it can knock on the outer wall of the conveying pipeline to shake off the fly ash adhering to its inner wall, effectively avoiding the phenomenon of fly ash adhering to and adsorbing on the inner wall of the conveying pipeline during the conveying process, more effectively preventing the deposition and caking of materials in the pipeline, and being beneficial to reducing the occurrence frequency of blockage. Therefore, it can reduce the processing interruption and downtime caused by cleaning blockages.

[0013] Second, by setting the sliding rod, when the rotating rod is tilted by the impact of the top block, the moving block moves horizontally along the outer wall of the moving rod. At the same time, the moving block drives the sliding block to move along the outer wall of the sliding rod, putting the sliding rod into a stressed state. When the top block rotates to a certain position and its protruding part moves away from the rotating rod, the pressure on the sliding rod turns into a reaction force, pushing the sliding block downward, causing the moving block to move along the moving rod again, thereby driving the rotating rod to reset, facilitating the next knocking. By setting the limiting block, the position of the moving block is limited to prevent the moving block from falling off the outer wall of the moving rod. By setting the rubber pad, the softness of the contact surface between the rotating rod and the outer wall of the conveying pipe can be improved, reducing the noise generated during its knocking.

[0014] III. By setting the rotating stirring blade, when fly ash is conveyed inside the conveying pipe, the rotating stirring blade will rotate along the outer wall of the rotating rod with the conveying air pressure inside the pipe, effectively preventing the fly ash from caking and blocking, improving the use efficiency. By setting the limiting ring, it can effectively prevent the rotating stirring blade from sliding along the outer wall of the rotating rod, improving the running stability of the rotating stirring blade.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will describe in detail the preferred embodiments of the present invention with reference to the accompanying drawings.

[0021] As Figures 1 - 3 shown, a fly ash conveying flue gas treatment system includes a connecting frame 1, the connecting frame 1 is fixedly installed on the top surface of the base 2, a ash storage tank 3 is fixedly installed inside the connecting frame 1, a ash discharge pipe 4 is fixedly installed inside the ash storage tank 3, one end of the ash discharge pipe 4 is fixedly installed with a conveying pipe 5, a mounting block 6 is fixedly installed on the top surface of the base 2, a stepper motor 7 is fixedly installed on the top surface of the mounting block 6, one end of the rotating shaft of the stepper motor 7 is fixedly installed with a top block 8, a mounting bracket 9 is fixed on the top surface of the connecting frame 1, and a rotating column 10 is fixedly installed inside the mounting bracket 9, and a rotating rod 11 is rotatably inserted on the outer wall of the rotating column 10.

[0022] In use, when the connecting frame 1 starts to operate and conveys the fly ash stored inside it to the inside of the ash discharge pipe 4 and then to the inside of the conveying pipe 5, the mounting block 6 is activated, driving the top block 8 to rotate. The protruding part of the top block 8 can push the rotating rod 11, enabling the rotating rod 11 to strike the outer wall of the adjacent conveying pipe 5, thereby striking the outer wall of the conveying pipeline and vibrating off the fly ash adhering to its inner wall. This can effectively avoid the phenomenon of fly ash adhering to and adsorbing to the inner wall of the conveying pipeline during transportation, more effectively prevent the deposition and caking of materials in the pipeline, and is conducive to reducing the occurrence frequency of blockages. Therefore, it can reduce the processing interruption and downtime caused by cleaning blockages.

[0023] As Figures 2 - 3 shown, a sliding rod 12 is fixedly installed inside the rotating rod 11. A spring 13 is slidably inserted on the outer wall of the sliding rod 12. A sliding block 14 is slidably inserted on the outer wall of the sliding rod 12. One end of the spring 13 is fixedly installed on the inner top surface of the rotating rod 11, and the other end of the spring 13 is fixedly installed on the top surface of the sliding block 14. A moving block 15 is rotatably clamped on the outer wall of the sliding block 14. A fixed frame 16 is fixedly installed on one side of the mounting frame 9, and a moving rod 17 is fixedly installed on one side of the fixed frame 16. The moving block 15 is movably inserted on the outer wall of the moving rod 17, and a limiting block 18 is fixedly installed at one end of the moving rod 17.

[0024] In use, by setting the sliding rod 12, when the rotating rod 11 is tilted by the impact of the top block 8, the moving block 15 moves horizontally along the outer wall of the moving rod 17. At the same time, the moving block 15 drives the sliding block 14 to move along the outer wall of the sliding rod 12, putting the sliding rod 12 into a stressed state. When the protruding part of the top block 8 rotates to a certain position and is far away from the rotating rod 11, the pressure on the sliding rod 12 turns into a reaction force, pushing the sliding block 14 downward, causing the moving block 15 to move along the moving rod 17 again, thereby driving the rotating rod 11 to reset, facilitating the next strike. By setting the limiting block 18, the position of the moving block 15 is limited to prevent the moving block 15 from falling off the outer wall of the moving rod 17.

[0025] As Figures 2 - 4 shown, a rubber pad 19 is fixedly installed on one side of the rotating rod 11. A rotating rod 20 is fixedly installed inside the conveying pipe 5. A rotating stirring blade 21 is inserted on the outer wall of the rotating rod 20. Two limiting rings 22 are arranged on both sides of the rotating stirring blade 21, and the limiting rings 22 are fixedly installed on the outer wall of the rotating rod 20.

[0026] In use, by setting the rubber pad 19, the softness of the contact surface between the rotating rod 11 and the outer wall of the conveying pipe 5 can be improved, and the noise generated during its knocking can be reduced. By setting the rotating stirring blade 21, when fly ash is conveyed inside the conveying pipe 5, the rotating stirring blade 21 will rotate along the outer wall of the rotating rod 20 with the conveying air pressure inside the pipe, effectively preventing the fly ash from caking and blocking, and improving the use efficiency. By setting the limiting ring 22, the rotating stirring blade 21 can be effectively prevented from sliding along the outer wall of the rotating rod 20, and the running stability of the rotating stirring blade 21 can be improved.
