Description
Technical Field
[0001] The utility model relates to the technical field of fly ash transportation, and particularly relates to a wear-resistant fly ash transportation pipeline. Background Art
[0002] A transportation pipeline is a pipeline system used to transport substances from one location to another. It usually consists of pipelines, connectors, support structures, control equipment, etc.
[0003] Currently, the amount of coal ash generated after boiler combustion is large, and the fluidity of coal ash is poor. During the transportation process by a silo pump, the transportation pipeline at the adjacent right-angle corner is often blocked. After the transportation pipeline is blocked, it is necessary to manually knock on the right-angle turn of the transportation pipeline to make the fly ash adhered to the transportation pipeline fall off, thereby dredging the transportation pipeline. Since the operation of the sludge incinerator needs to be stopped when manually cleaning the transportation pipeline, and the sludge incinerator can only continue to operate after manually dredging the transportation pipeline. At present, manual blockage removal is extremely troublesome. When the blockage is serious, it is even necessary to cut off the transportation pipeline for treatment, resulting in a large waste of manpower and material resources, and also causing environmental impacts. Therefore, the utility model provides a wear-resistant fly ash transportation pipeline to meet the requirements. Summary of the Utility Model
[0004] To solve the above technical problems, the utility model provides the following technical solutions:
[0005] A wear-resistant fly ash transportation pipeline includes a right-angle transportation pipeline main body. An unclogging component is arranged outside the right-angle of the right-angle transportation pipeline main body. The unclogging component is used for unclogging and preventing blockage of the pipeline. The unclogging component includes a guide sleeve fixedly connected to the right-angle of the right-angle transportation pipeline main body. A connecting plate is fixedly connected to the top of the guide sleeve. A connecting column is slidably connected inside the connecting plate. The bottom end of the connecting column penetrates and extends into the interior of the right-angle transportation pipeline main body, and a dust cleaning plate is fixedly connected to the bottom of the connecting column.
[0006] Optionally, both sides of the dust cleaning plate are fixedly connected to the inner wall of the right-angle transportation pipeline main body, and the thickness value of the dust cleaning plate is one centimeter.
[0007] Optionally, a plurality of equally spaced deformation holes are formed inside the dust cleaning plate.
[0008] Optionally, a driving motor is fixedly connected to the top of the connecting plate. A driving gear is fixedly connected to the output shaft of the driving motor. A toothed plate is fixedly connected to the top end of the connecting column. One side of the toothed plate meshes with the driving gear.
[0009] Optionally, both sides of the bottom of the connecting plate are fixedly connected with inclined connecting frames, and the ends of the two connecting frames are fixedly connected with mounting sleeves, and the two mounting sleeves are respectively installed on two right-angled sides of the main body of the right-angled conveying pipeline through bolts.
[0010] Optionally, a first connecting rod is rotatably connected to both sides of the connecting column, a guide rod is fixedly connected to the inside of each connecting frame, a second connecting rod is slidably connected to the outside of the guide rod, the other end of the second connecting rod is rotatably connected to the other end of the first connecting rod, and a knocking plate is rotatably connected to the bottom of the connection between the second connecting rod and the first connecting rod. Moving grooves for the movement of the first connecting rod are formed on both sides of the guide sleeve.
[0011] Optionally, a wear-resistant layer is provided on the inner wall of the main body of the right-angled conveying pipeline.
[0012] Compared with the prior art, the utility model has at least the following beneficial effects:
[0013] In the above solution, by setting the dredging component, the driving motor drives the driving gear to rotate, and then drives the toothed plate and the connecting column to move up and down, so that the ash cleaning plate reciprocates inside the main body of the right-angled conveying pipeline. This automated dredging method not only improves work efficiency but also reduces the need for manual intervention, avoiding the shutdown time of the sludge incinerator caused by manual cleaning.
[0014] In the above solution, through the connection structure of the first connecting rod, the second connecting rod and the knocking plate, when the ash cleaning plate moves up and down, it will drive the knocking plate to knock on the inner wall of the main body of the right-angled conveying pipeline. This additional vibration effect helps to loosen and remove the fly ash adhering to the inner wall of the pipeline, further enhancing the dredging effect.
[0015] In the above solution, the wear-resistant layer added to the inner wall of the main body of the right-angled conveying pipeline can effectively resist the wear of fly ash, extend the service life of the pipeline, and reduce the replacement cost caused by pipeline wear.

[0022] The following combines the accompanying drawings and specific embodiments to describe in detail a wear-resistant fly ash conveying pipeline provided by the present utility model; at the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are preferred embodiments, and for some well-known technologies, those skilled in the art can also adopt other alternative methods.
[0023] As Figures 1 to 4As shown in the figure, an embodiment of the present utility model provides a wear-resistant fly ash conveying pipeline, which includes a right-angle conveying pipeline main body 1. An unclogging assembly is provided outside the right angle of the right-angle conveying pipeline main body 1. The unclogging assembly is used for unclogging and preventing blockage of the pipeline. The unclogging assembly includes a guide sleeve 3 fixedly connected to the right angle of the right-angle conveying pipeline main body 1. A connecting plate 5 is fixedly connected to the top of the guide sleeve 3. A connecting column 10 is slidably connected inside the connecting plate 5. The bottom end of the connecting column 10 penetrates and extends into the inside of the right-angle conveying pipeline main body 1, and a dust cleaning plate 9 is fixedly connected to the bottom of the connecting column 10. Both sides of the dust cleaning plate 9 are fixedly connected to the inner wall of the right-angle conveying pipeline main body 1. The thickness value of the dust cleaning plate 9 is one centimeter. A plurality of equidistantly distributed deformation holes 901 are formed inside the dust cleaning plate 9. A driving motor 7 is fixedly connected to the top of the connecting plate 5. A driving gear 8 is fixedly connected to the output shaft of the driving motor 7. A toothed plate 6 is fixedly connected to the top end of the connecting column 10. One side of the toothed plate 6 meshes with the driving gear 8. Both sides of the bottom of the connecting plate 5 are fixedly connected with inclined connecting frames 4. The ends of the two connecting frames 4 are both fixedly connected with mounting sleeves 2. The two mounting sleeves 2 are respectively installed on the two right-angle sides of the right-angle conveying pipeline main body 1 through bolts. First, fix the mounting sleeves 2 on the two right-angle sides of the right-angle conveying pipeline main body 1 through bolts to ensure stable installation. Fix the connecting frames 4 on the mounting sleeves 2 and fix the connecting plate 5 on the top of the guide sleeve 3 to form the overall framework of the unclogging assembly. When there is a risk of blockage or the pipeline is already blocked during the fly ash conveying process, start the driving motor 7. The output shaft of the driving motor 7 drives the driving gear 8 to rotate. Since the toothed plate 6 meshes with the driving gear 8, the rotation of the driving gear 8 will drive the toothed plate 6 and the connecting column 10 fixed thereto to move up and down. As the connecting column 10 moves up and down, the dust cleaning plate 9 reciprocates inside the right-angle conveying pipeline main body 1. The thickness of the dust cleaning plate 9 is appropriate, which can effectively scrape the fly ash on the inner wall of the pipeline. At the same time, the design of the deformation holes 901 inside it helps to reduce the accumulation of fly ash. According to the actual operation situation, continuously monitor the state of the conveying pipeline and adjust the operating parameters of the driving motor 7 in a timely manner to achieve the best unclogging effect. It realizes the automatic unclogging of the fly ash conveying pipeline, greatly improves the work efficiency, reduces the need for manual intervention, and can carry out unclogging operations without stopping the operation of the sludge incinerator, significantly reducing the outage time caused by pipeline blockage and reducing the maintenance costs caused by manual cleaning and pipeline replacement.
[0024] As Figures 1 to 4As shown, on both sides of the connecting column 10, there are first connecting rods 11 rotatably connected. Inside each connecting frame 4, there is a guide rod 13 fixedly connected. The outer part of the guide rod 13 is slidably connected with a second connecting rod 12. The other end of the second connecting rod 12 is rotatably connected to the other end of the first connecting rod 11. And at the bottom of the connection between the second connecting rod 12 and the first connecting rod 11, there is a striking plate 14 rotatably connected. On both sides of the guide sleeve 3, there are moving grooves for the movement of the first connecting rod 11. When the first connecting rod 11 moves downward synchronously with the connecting column 10, since one end of the first connecting rod 11 is rotatably connected to the connecting column 10, when the connecting column 10 moves downward under the action of the driving force, the first connecting rod 11 will also move downward. This downward movement is achieved through the rotational connection between the connecting column 10 and the first connecting rod 11. Therefore, the downward movement of the first connecting rod 11 will be accompanied by a certain rotation. One end of the second connecting rod 12 is rotatably connected to the other end of the first connecting rod 11, and the other end slides along the guide rod 13. When the first connecting rod 11 moves downward, it will push the second connecting rod 12 to slide along the guide rod 13 through the rotational connection. Due to the sliding connection between the second connecting rod 12 and the guide rod 13, and its rotational connection with the first connecting rod 11, the second connecting rod 12 will also rotate during the sliding process. The degree and direction of this rotation depend on the position of the connection point between the first connecting rod 11 and the second connecting rod 12 and the guiding effect of the guide rod 13. The striking plate 14 is designed at the rotational connection with the second connecting rod 12 and the first connecting rod 11, so that it can move along with the sliding and rotation of the second connecting rod 12. When the second connecting rod 12 slides and rotates along the guide rod 13 to a certain position, the striking plate 14 will contact the inner wall of the right-angle conveying pipe main body 1 or other components that need to be struck. As the first connecting rod 11 and the second connecting rod 12 continue to move, the striking plate 14 will strike the pipe. This striking action helps to loosen and remove the fly ash adhering to the inner wall of the pipe, thus playing a role in dredging the pipe.
[0025] As Figures 1 to 4 shown, on the inner wall of the right-angle conveying pipe main body 1, there is a wear-resistant layer, which can effectively extend the service life of the right-angle conveying pipe main body 1.
[0026] Working principle provided by the utility model: First, fix the mounting sleeve 2 on the two right-angled sides of the right-angled conveying pipeline main body 1 through bolts to ensure firm installation. Fix the connecting frame 4 on the mounting sleeve 2, and fix the connecting plate 5 on the top of the guiding sleeve 3 to form the overall framework of the dredging assembly. When there is a risk of blockage or the pipeline is already blocked during the fly ash conveying process, start the driving motor 7. The output shaft of the driving motor 7 drives the driving gear 8 to rotate. Since the toothed plate 6 meshes with the driving gear 8, the rotation of the driving gear 8 drives the toothed plate 6 and the connecting column 10 fixed thereto to move up and down. With the up and down movement of the connecting column 10, the ash cleaning plate 9 reciprocates inside the right-angled conveying pipeline main body 1. The thickness of the ash cleaning plate 9 is appropriate, and it can effectively scrape the fly ash on the inner wall of the pipeline. When the first connecting rod 11 moves down synchronously with the connecting column 10, since one end of the first connecting rod 11 is rotatably connected to the connecting column 10, when the connecting column 10 moves down under the action of the driving force, the first connecting rod 11 will also move down. This downward movement is achieved through the rotational connection between the connecting column 10 and the first connecting rod 11. Therefore, the downward movement of the first connecting rod 11 will be accompanied by a certain rotation. One end of the second connecting rod 12 is rotatably connected to the other end of the first connecting rod 11, and the other end slides along the guiding rod 13. When the first connecting rod 11 moves down, it will push the second connecting rod 12 to slide along the guiding rod 13 through the rotational connection. Due to the sliding connection between the second connecting rod 12 and the guiding rod 13, and its rotational connection with the first connecting rod 11, the second connecting rod 12 will also rotate during the sliding process. The degree and direction of this rotation depend on the position of the connection point between the first connecting rod 11 and the second connecting rod 12 and the guiding effect of the guiding rod 13. The knocking plate 14 is designed at the rotational connection of the second connecting rod 12 and the first connecting rod 11, so that it can move with the sliding and rotation of the second connecting rod 12. When the second connecting rod 12 slides along the guiding rod 13 and rotates to a certain position, the knocking plate 14 will contact the inner wall of the right-angled conveying pipeline main body 1 or other components that need to be knocked. With the continuous movement of the first connecting rod 11 and the second connecting rod 12, the knocking plate 14 will knock on the pipeline. This knocking action helps to loosen and remove the fly ash adhering to the inner wall of the pipeline, thus playing a role in dredging the pipeline.
