Description

Technical Field

[0001] The invention relates to the technical field of curved coal dropping pipes, in particular to a hyperbolic coal dropping pipe. Background Art

[0002] The curved coal drop pipe is a device used in coal transportation systems in thermal power plants, steel plants, etc. It is used to smoothly transport coal from a high place to a lower coal receiving device (such as coal storage bins, belt conveyors, etc.). Its main function is to reduce the breakage rate and dust volume of coal during the falling process, ensuring transportation efficiency and environmental protection requirements.

[0003] However, the existing curved coal drop pipe still has the following defects when in use:

[0004] 1. Existing curved coal-dropping pipes In the curved coal-dropping pipes, especially in the curved parts and the narrowed parts of the pipe section, due to the too steep bending angle or too small curvature radius, the coal is easy to accumulate in the bends, resulting in blockage. Especially when transporting coal with high water content or uneven particle size, the blockage phenomenon is more serious. Once the pipeline is installed, it is difficult to adjust its curvature and it needs to be shut down for maintenance, which affects production efficiency and causes poor coal flow.

[0005] 2. In addition, in some applications, the deceleration effect of the curved coal drop pipe is not obvious. If the deceleration only relies on the curved structure, the effect is limited. In addition, the existing design lacks additional auxiliary structures such as deceleration plates and buffer blocks, resulting in coal still impacting the coal-receiving equipment at a relatively high speed, causing equipment wear or increased coal crushing rate.

[0006] Therefore, a hyperbolic coal drop pipe is proposed to solve the above problems. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a hyperbolic coal drop pipe to solve the problems in the prior art that coal is easily blocked at the bends of the pipe and coal blocks are easily damaged, resulting in serious wear of the pipe.

[0008] To achieve the above object, the present invention provides the following technical solutions: a hyperbolic coal drop pipe, comprising a hyperbolic pipe, an airflow spray gun device is installed on the outer surface of the hyperbolic pipe, a dust isolation chamber is fixedly connected to the lower surface of the hyperbolic pipe, a dust isolation net is installed on the inner wall of the dust isolation chamber, and also includes an anti-blocking buffer warning mechanism and an angle adjustment mechanism, the anti-blocking buffer warning mechanism is arranged on the inner wall of the hyperbolic pipe, and the angle adjustment mechanism is arranged in the middle of the hyperbolic pipe;

[0009] The anti-blocking buffer warning mechanism is used for buffering and reducing vibration when the coal blocks fall;

[0012] As an improvement, a conical spring is fixedly connected to the bottom of the arc surface pressing plate, and one end of the conical spring away from the arc surface pressing plate is fixedly connected in the control chamber. A striking block is provided in the middle of the arc surface vibration damping plate, and a protrusion is fixedly connected to the inner wall of the hyperbolic tube near the middle of the arc surface vibration damping plate, and the protrusion is fixedly connected on the movement trajectory of the striking block of the arc surface vibration damping plate.

[0013] As an improvement, the angle adjustment mechanism includes an adjusting rod, the outer surfaces at both ends of the adjusting rod are rotatably connected to the hyperbolic tube, the outer surface of the middle part of the adjusting rod is rotatably connected to a protective cover, a worm is provided in the middle of the protective cover, both ends of the worm are fixedly connected to the middle part of the adjusting rod, a worm wheel is meshed on the worm tooth surface, a threaded shaft is symmetrically fixedly connected to the middle part of the worm wheel, the non-threaded part of the threaded shaft is rotatably connected to the protective cover, and a T-shaped threaded sleeve is threadedly connected to the end of the threaded shaft away from the worm wheel.

[0014] As an improvement, the angle adjustment mechanism also includes a first curved telescopic plate, an adjustment groove is opened on the inner side of the hyperbolic surface near the middle of the hyperbolic tube, and the adjustment groove is communicated with the hyperbolic tube pipeline, one end of the first curved telescopic plate is rotatably connected to the second curved telescopic plate, the other end of the first curved telescopic plate is rotatably connected to one end of the adjustment groove of the hyperbolic tube, the second curved telescopic plate is rotatably connected to the other end of the adjustment groove away from one end of the first curved telescopic plate, and the outer surfaces of both sides of the first curved telescopic plate and the second curved telescopic plate are slidably connected in the adjustment groove opened in the hyperbolic tube.

[0015] As an improvement, the upper surface of the T-shaped threaded sleeve away from the threaded shaft is rotatably connected to the second arc-shaped telescopic plate, and the lower surface of the T-shaped threaded sleeve away from the threaded shaft is rotatably connected to the first arc-shaped telescopic plate.

[0016] As an improvement, a vibration mechanism is also provided on the outer surface of both ends of the hyperbolic tube, and the vibration mechanism includes a driving tooth. The middle part of the driving tooth is rotatably connected to the outer surface of the hyperbolic tube, and the tooth surface of the driving tooth is meshed with a gear turntable. Both ends of the gear turntable are rotatably connected to the outer surface of the hyperbolic tube. A vibration groove is opened on the hyperbolic tube near the inner surface of the gear turntable, and a telescopic protrusion is fixedly connected to the circumference of the inner surface of the gear turntable.

[0017] As an improvement, a compression spring is sleeved on the outer surface of the telescopic protrusion, one end of the compression spring is fixedly connected to the gear turntable, and the other end of the compression spring is fixedly connected to the telescopic protrusion. An arc-surface extrusion block is provided on the side of the telescopic protrusion away from the compression spring, and the circumference of the arc-surface extrusion block is fixedly connected to the vibration groove opened in the hyperbolic tube.

[0018] Compared with the prior art, the hyperbolic coal dropping pipe provided by the present invention has the following beneficial effects:

[0019] 1. Through the design of the first curved telescopic plate and the second curved telescopic plate in the present invention, the curvature of the curved surface when the coal block falls can be adjusted by setting it at the hyperbolic pipe, so that the coal block can flexibly adapt to the transportation of coal blocks in different environments when falling, thereby reducing the bending angle or curvature radius being too small, which makes it easy for coal to accumulate at the bend, and reducing the blockage of the hyperbolic pipe caused by coal during transportation;

[0020] Compared with the prior art in which it is difficult to adjust the curvature of the pipeline once it is installed, the arrangement of the present invention can also avoid the phenomenon that it is difficult to adjust the curvature once the installation is completed. The operator only needs to flexibly adjust the rotation of the adjustment rod according to the on-site operation requirements to complete the adjustment of the curvature of the hyperbolic pipe. Not only can the hyperbolic pipe be flexibly adjusted under different transportation conditions, increasing the flexibility and adaptability of pipeline transportation, but also reducing the downtime for maintenance in the production process, further improving production efficiency.

[0021] 2. In the prior art, when coal blocks fall to the bifurcation of the hyperbolic pipe and slow down, they are often broken by impact. However, the arc-surface pressing plate and the conical spring in the present invention effectively absorb the impact force of the coal blocks when they fall, thereby significantly reducing the breakage of the coal blocks in the process of being diverted to the arc surface of the hyperbolic pipe. In addition, the vibration-damping block is installed on the inner wall of the hyperbolic pipe at the bend of the hyperbolic pipe in the present invention, which can effectively reduce the impact of the coal blocks on the inner wall of the hyperbolic pipe and reduce pipe wear.

[0022] The linkage design between the arc-surface vibration damping plate and the arc-surface pressing plate in the present invention not only enhances the cushioning effect when the coal blocks fall, but also disperses the impact force of the coal blocks when they fall, thereby reducing the direct impact of the coal blocks on the wall of the hyperbolic pipe, thereby reducing the wear of the pipe wall and extending the service life of the pipe. In addition, the impact design between the arc-surface vibration damping plate and the pipe wall in the present invention can effectively disturb the flow state of the coal blocks, reduce the accumulation tendency of the coal blocks at the bifurcation of the hyperbolic pipe, and thus greatly reduce the risk of blockage.

[0023] 3. In the present invention, the collision between the arc extrusion block and the telescopic protrusion can prevent the blockage of the hyperbolic pipe caused by the transportation of coal blocks, and the connection between the airflow spray gun device and the hyperbolic pipe of the present invention can speed up the transportation efficiency of coal. At the same time, the conical dust isolation chamber arranged at the bottom of the hyperbolic pipe can reduce the diffusion of coal dust when the coal falls, and the dust isolation net can filter large particles of dust. The dust collection port at the upper end of the dust isolation chamber can be directly connected to the dust purifier, thereby effectively reducing the dust phenomenon at the discharge port.

[0037] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0038] Example

[0039] Please refer to Figures 1 to 7 As shown:

[0040] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a hyperbolic coal drop pipe, including a hyperbolic pipe 1, an airflow spray gun device 11 is installed on the outer surface of the hyperbolic pipe 1, a dust isolation chamber 12 is fixedly connected to the lower surface of the hyperbolic pipe 1, and a dust isolation net 13 is installed on the inner wall of the dust isolation chamber 12, and also includes an anti-blocking buffer warning mechanism 2 and an angle adjustment mechanism 3, the anti-blocking buffer warning mechanism 2 is arranged on the inner wall of the hyperbolic pipe 1, and the angle adjustment mechanism 3 is arranged in the middle of the hyperbolic pipe 1;

[0042] The angle adjustment mechanism 3 is used for adjusting the arc surface of the hyperbolic tube 1;

[0043] The anti-blocking buffer warning mechanism 2 includes a curved pressing plate 21, the outer surface of which is slidably connected to a control chamber 22, the bottom of which is fixedly connected to the inner wall of the hyperbolic tube 1, and rotating holes are provided on both sides of the middle of the control chamber 22, and curved vibration damping plates 23 are rotatably connected in the rotating holes on both sides of the control chamber 22, and the outer surface of the upper end of the curved vibration damping plate 23 is rotatably connected to the curved pressing plate 21;

[0044] A conical spring 24 is fixedly connected to the bottom of the arc surface pressing plate 21, and one end of the conical spring 24 away from the arc surface pressing plate 21 is fixedly connected in the control chamber 22. A striking block is arranged in the middle of the arc surface vibration damping plate 23, and a convex block is fixedly connected to the inner wall of the hyperbolic tube 1 near the middle of the arc surface vibration damping plate 23, and the convex block is fixedly connected on the motion track of the striking block of the arc surface vibration damping plate 23;

Compared with the prior art, through the implementation of this embodiment, the linkage design between the arc vibration damping plate 23 and the arc pressure plate 21 not only enhances the buffering effect when the coal blocks fall, but also disperses the impact force of the coal blocks when they fall, thereby reducing the direct impact of the coal blocks on the wall of the hyperbolic pipe 1, thereby reducing the wear of the pipe wall and extending the service life of the pipeline. In addition, the impact design between the arc vibration damping plate 23 and the pipe wall in the present invention can effectively disturb the flow state of the coal blocks, reduce the accumulation tendency of the coal blocks at the bifurcation of the hyperbolic pipe 1, and thus greatly reduce the risk of blockage.

[0050] The upper surface of the T-shaped threaded sleeve 36 away from the threaded shaft 35 is rotatably connected to the second arc-shaped telescopic plate 302, and the lower surface of the T-shaped threaded sleeve 36 away from the threaded shaft 35 is rotatably connected to the first arc-shaped telescopic plate 301;

[0051] A vibration mechanism 4 is also provided on the outer surface of both ends of the hyperbolic tube 1. The vibration mechanism 4 includes a driving tooth 41. The middle part of the driving tooth 41 is rotatably connected to the outer surface of the hyperbolic tube 1. The tooth surface of the driving tooth 41 is meshed with a gear turntable 42. Both ends of the gear turntable 42 are rotatably connected to the outer surface of the hyperbolic tube 1. A vibration groove is provided on the inner surface of the hyperbolic tube 1 near the gear turntable 42. A telescopic protrusion 43 is fixedly connected to the inner surface of the gear turntable 42.

[0052] A compression spring 44 is sleeved on the outer surface of the telescopic protrusion 43, one end of the compression spring 44 is fixedly connected to the gear turntable 42, and the other end of the compression spring 44 is fixedly connected to the telescopic protrusion 43. A curved surface extrusion block 45 is arranged on the side of the telescopic protrusion 43 away from the compression spring 44, and the circumference of the curved surface extrusion block 45 is fixedly connected to the vibration groove opened in the hyperbolic tube 1;

[0053] Among them: the vibration mechanism 4 is symmetrically arranged on the outer surfaces of both sides of the hyperbolic tube 1, the middle part of the driving tooth 41 is fixedly connected to the motor driving shaft, and the motor is installed on the hyperbolic tube 1, and the airflow pipes are connected to both sides of the airflow spray gun equipment 11, and the airflow pipes are connected to the hyperbolic tube 1. At the same time, a filter is installed at the airflow hole of the hyperbolic tube 1 to prevent impurities from flowing back.

[0054] Compared with the prior art in which it is difficult to adjust the curvature of the pipeline once the installation is completed, the present embodiment and the arrangement of the present invention can also avoid the phenomenon that it is difficult to adjust the curvature once the installation is completed. The operator only needs to flexibly adjust the rotation of the adjustment rod 31 according to the on-site operation requirements to complete the adjustment of the curvature of the hyperbolic pipe 1. Not only can the hyperbolic pipe 1 be flexibly adjusted under different transportation conditions, increasing the flexibility and adaptability of pipeline transportation, but also reducing the downtime for maintenance in the production process, which can further improve production efficiency.

[0055] Everything in the above example works like this:

[0056] In the initial state: the micro motor installed on the hyperbolic tube 1 is not started, and the air flow spray gun device 11 is not started.

[0057] The following is the working process of the anti-blocking buffer warning mechanism 2 for buffering and shock absorption when the coal block falls:

[0058] When using, Figure 3As shown, when the coal block falls into the bifurcation of the hyperbolic pipe 1 at the upper right side of the hyperbolic pipe 1, part of the coal block will fall onto the upper surface of the arc pressing plate 21 under the action of gravity. Since the arc pressing plate 21 is slidably connected in the control chamber 22, and the bottom of the arc pressing plate 21 is fixedly connected to the conical spring 24, the fallen coal block will drive the arc pressing plate 21 to slide downward, and the conical spring 24 will begin to be compressed. Since the arc pressing plate 21 is rotatably connected to the arc damping plates 23 on both sides of the bottom, and the arc damping plates 23 are rotatably connected to both sides of the control chamber 22, when the arc pressing plate 21 slides downward, it will drive the arc damping plates 23 to start rotating. Since the arc damping plates 23 are symmetrically and evenly arranged in the control chamber 22, their functional principles are the same, so only the following examples are shown. Figure 3 The arc surface pressing plate 21 is described as a group of numbers shown. At this time, as the arc surface pressing plate 21 slides downward, the arc surface vibration damping plate 23 starts to swing upward in the clockwise direction. Since coal blocks continue to fall into the pipeline, the arc surface vibration damping plate 23 can slow down the impact of the coal blocks on the inner wall of the hyperbolic pipe 1. The arc surface pressing plate 21 and the conical spring 24 of the present invention effectively absorb the impact force of the coal blocks when they fall, thereby significantly reducing the crushing of the coal blocks in the process of being diverted to the arc surface of the hyperbolic pipe 1. In addition, the vibration damping block 303 is installed on the inner wall of the hyperbolic pipe 1 at the bend of the hyperbolic pipe 1 in the present invention, which can effectively reduce the impact of the coal blocks on the inner wall of the hyperbolic pipe 1 and reduce the wear of the pipe.

[0059] The linkage design between the arc damping plate 23 and the arc pressing plate 21 in the present invention not only enhances the buffering effect when the coal blocks fall, but also disperses the impact force of the coal blocks when they fall, thereby reducing the direct impact of the coal blocks on the wall of the hyperbolic pipe 1, thereby reducing the wear of the pipe wall and extending the service life of the pipe. In addition, the impact design between the arc damping plate 23 and the pipe wall in the present invention can effectively disturb the flow state of the coal blocks, reduce the accumulation tendency of the coal blocks at the bifurcation of the hyperbolic pipe 1, and thus greatly reduce the risk of blockage.

[0060] In addition, when the coal blocks are transported with high viscosity, if the coal blocks are blocked on the arc surface pressing plate 21, the arc surface pressing plate 21 will be continuously pressed. At this time, because the present invention innovatively installs a pressure sensor device at the bottom of the conical spring 24, the inner wall of the sensor device is set to have a maximum pressing threshold time. Once the pressing time exceeds the preset threshold, the sensor device will respond quickly and send the emergency situation to the terminal controller in the form of an electrical signal. After the terminal controller receives the signal sent by the sensor device, the terminal controller will immediately take action to directly control the micro motor located on the hyperbolic tube 1 to start;

[0061] At this time, because the driving tooth 41 is fixedly connected to the micro-motor driving shaft, and the tooth surface of the driving tooth 41 meshes with the tooth surface of the gear rotating disk 42, the counterclockwise rotation of the driving tooth 41 will drive the gear rotating disk 42 to rotate clockwise and connect to the hyperbolic tube 1. Figure 7 As shown, since the telescopic protrusion 43 is circumferentially fixedly connected to the gear turntable 42, and the arc surface extrusion block 45 is circumferentially fixedly connected in the vibration groove opened in the hyperbolic tube 1, and since the compression spring 44 is sleeved on the telescopic protrusion 43, when the gear turntable 42 rotates clockwise, the telescopic protrusion 43 will start to squeeze the inclined surface of the arc surface extrusion block 45. When the gear turntable 42 continues to rotate and the telescopic protrusion 43 is separated from the extrusion of the arc surface extrusion block 45, the elastic action of the compression spring 44 will drive the telescopic protrusion 43 to quickly stretch and hit the inner wall of the hyperbolic tube 1. At this time, the impact of the telescopic protrusion 43 will drive the coal block blocked in the hyperbolic tube 1 to vibrate. At this time, Excessive vibration will cause the blocked coal blocks to gradually fall off. In the present invention, the collision between the arc extrusion block 45 and the telescopic protrusion 43 can cause the blockage of the hyperbolic tube 1 during the transportation of coal blocks. Moreover, the connection between the airflow spray gun device 11 and the hyperbolic tube 1 of the present invention can speed up the transportation efficiency of the coal. At the same time, the conical dust isolation chamber 12 set at the bottom of the hyperbolic tube 1 can reduce the diffusion of coal dust when the coal falls, and the dust isolation net 13 can filter large particles of dust. The dust collection port at the upper end of the dust isolation chamber 12 can be directly connected to the dust purifier, thereby effectively reducing the dust phenomenon at the discharge port.

[0062] Please refer to the above working process Figures 1 to 7 .

[0063] The following is the working process of the angle adjustment mechanism 3 for adjusting the arc surface of the hyperbolic tube 1:

[0064] As described above, when conveying different coal blocks, the operator can adjust the adjusting rod 31 to adapt to the speed of different coal blocks falling. At this time, the operator manually rotates the adjusting rod 31, such as Figure 4As shown, because the adjusting rod 31 is fixedly connected to the middle part of the worm 32, and the worm 32 is meshed with the worm wheel 33, the rotation of the worm 32 will drive the worm wheel 33 to drive the threaded shaft 35 fixedly connected in the middle part to start to rotate synchronously. At this time, because the threaded shaft 35 is threadedly connected in the T-shaped threaded sleeve 36, the rotation of the threaded shaft 35 will drive the T-shaped threaded sleeve 36 to start to move horizontally, and because the end of the T-shaped threaded sleeve 36 away from the threaded shaft 35 is rotatably connected to the first curved telescopic plate 301 and the first curved telescopic plate 301, respectively. , and both ends of the first curved telescopic plate 301 and the second curved telescopic plate 302 are rotatably connected to the hyperbolic tube 1, and at the same time, the first curved telescopic plate 301 is rotatably connected to the second curved telescopic plate 302. At this time, by changing the horizontal displacement of the T-shaped threaded sleeve 36, the first curved telescopic plate 301 and the first curved telescopic plate 301 can be driven to slide on the inner wall of the hyperbolic tube 1. Therefore, the operator can simultaneously adjust the position changes of the first curved telescopic plate 301 and the second curved telescopic plate 302 located on both sides of the hyperbolic tube 1 by rotating the adjusting rod 31.

[0065] Compared with the prior art in which it is difficult to adjust the curvature of the pipeline once it is installed, the configuration of the present invention can also avoid the phenomenon that it is difficult to adjust the curvature once the installation is completed. The operator only needs to flexibly adjust the rotation of the adjustment rod 31 according to the on-site operation requirements to complete the adjustment of the curvature of the hyperbolic pipe 1. Not only can the hyperbolic pipe 1 be flexibly adjusted under different transportation conditions, increasing the flexibility and adaptability of pipeline transportation, but also reducing the downtime for maintenance in the production process, which can further improve production efficiency.
