Description

Technical Field

[0001] This invention relates to the field of curved coal chutes, specifically a hyperbolic coal chute. Background Technology

[0002] A curved coal chute is a device used in coal conveying systems of thermal power plants, steel mills, and other similar facilities. It is used to smoothly transport coal from a higher position to a lower receiving device (such as a coal storage silo or belt conveyor). Its main function is to reduce coal breakage and dust generation during the descent, ensuring both conveying efficiency and environmental compliance.

[0003] However, the existing curved coal chutes still have the following defects in use:

[0004] 1. In existing curved coal chutes, especially at bends and narrowing sections, coal tends to accumulate at bends due to steep angles or small radii of curvature. This can lead to blockages, particularly when transporting coal with high moisture content or uneven particle size. Furthermore, adjusting the curvature of the chutes after installation is difficult and requires downtime for maintenance, impacting production efficiency and hindering coal flow.

[0005] 2. In addition, in some applications, the deceleration effect of curved coal drop pipes is not obvious. If only the bending structure is relied upon for deceleration, the effect is limited. Furthermore, the existing design lacks additional auxiliary structures such as deceleration plates and buffer blocks, which causes coal to still impact the coal receiving equipment at a high speed, resulting in equipment wear or increased coal breakage rate.

[0006] Therefore, a hyperbolic coal chute was 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 chute to solve the problems in the prior art where coal is easily blocked at the bends of the pipe and coal blocks are easily damaged, resulting in severe pipe wear.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a hyperbolic coal chuting pipe, comprising a hyperbolic pipe, an airflow spray gun device installed on the outer surface of the hyperbolic pipe, a dust-proof chamber fixedly connected to the lower surface of the hyperbolic pipe, a dust-proof net installed on the inner wall of the dust-proof chamber, and further comprising an anti-blocking buffer warning mechanism and an angle adjustment mechanism, wherein the anti-blocking buffer warning mechanism is disposed on the inner wall of the hyperbolic pipe, and the angle adjustment mechanism is disposed in the middle of the hyperbolic pipe;

[0009] The anti-blocking buffer and early warning mechanism is used for buffering and vibration reduction when coal blocks fall.

[0010] The angle adjustment mechanism is used for adjusting the arc surface of the hyperbolic tube.

[0011] As an improvement, the anti-blocking buffer warning mechanism includes an arc-shaped pressing plate, a control chamber is slidably connected to the outer surface of the arc-shaped pressing plate, the bottom of the control chamber is fixedly connected to the inner wall of the hyperbolic tube, rotating holes are opened on both sides of the middle of the control chamber, and arc-shaped damping plates are rotatably connected to the rotating holes on both sides of the control chamber, and the upper outer surface of the arc-shaped damping plates is rotatably connected to the arc-shaped pressing plate.

[0012] As an improvement, a conical spring is fixedly connected to the bottom of the arc-shaped pressing plate, and the end of the conical spring away from the arc-shaped pressing plate is fixedly connected in the control room. A striking block is provided in the middle of the arc-shaped damping plate, and a protrusion is fixedly connected to the inner wall of the hyperboloid tube near the middle of the arc-shaped damping plate. The protrusion is fixedly connected to the movement trajectory of the striking block of the arc-shaped damping plate.

[0013] As an improvement, the angle adjustment mechanism includes an adjustment rod, the outer surfaces of both ends of which are rotatably connected to a hyperbolic tube, a protective cover rotatably connected to the outer surface of the middle part of the adjustment rod, a worm gear disposed in the middle of the protective cover, the two ends of the worm gear being fixedly connected to the middle part of the adjustment rod, the worm gear teeth meshing with a worm wheel, a threaded shaft symmetrically fixedly connected to the middle part of the worm wheel, the non-threaded part of the threaded shaft being rotatably connected to the protective cover, and a T-shaped threaded sleeve threadedly connected to the end of the threaded shaft away from the worm wheel.

[0014] As an improvement, the angle adjustment mechanism further includes a first arc-shaped telescopic plate. An adjustment groove is provided on the inner side of the hyperboloid near the middle of the hyperboloid, and the adjustment groove is connected to the hyperboloid pipe. One end of the first arc-shaped telescopic plate is rotatably connected to a second arc-shaped telescopic plate, and the other end of the first arc-shaped telescopic plate is rotatably connected to one end of the adjustment groove of the hyperboloid. The end of the second arc-shaped telescopic plate away from the first arc-shaped telescopic plate is rotatably connected to the other end of the adjustment groove. The outer surfaces of both sides of the first arc-shaped telescopic plate and the second arc-shaped telescopic plate are slidably connected in the adjustment groove provided in the hyperboloid.

[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 surfaces of both ends of the hyperbolic tube. The vibration mechanism includes a drive tooth, the middle of which is rotatably connected to the outer surface of the hyperbolic tube. The tooth surface of the drive tooth meshes with a gear turntable. The two ends of the gear turntable are rotatably connected to the outer surface of the hyperbolic tube. A vibration groove is opened on the inner surface of the hyperbolic tube near the gear turntable. 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 fitted 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-shaped extrusion block is provided on the side of the telescopic protrusion away from the compression spring. The arc-shaped extrusion block is circumferentially fixedly connected to the vibration groove opened in the hyperbolic tube.

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

[0019] 1. With the design of the first arc-shaped telescopic plate and the second arc-shaped telescopic plate in this invention, the arc curvature of the coal block can be adjusted when the coal block falls through the hyperbolic pipe, so that the coal block can flexibly adapt to the transportation of coal blocks in different environments when falling. This can reduce the problem of coal accumulating at the bend due to the bending angle or the radius of curvature being too small, and reduce the blockage of the hyperbolic pipe during coal transportation.

[0020] Compared to existing technologies where it is difficult to adjust the curvature of a pipeline after installation, this invention avoids the difficulty of adjusting the curvature after installation. Operators only need to flexibly adjust the rotation of the adjusting rod according to the on-site operation requirements to adjust the curvature of the hyperbolic pipe. This not only allows the hyperbolic pipe to be flexibly adjusted under different transportation conditions, increasing the flexibility and adaptability of pipeline transportation, but also reduces downtime for maintenance during production, further improving production efficiency.

[0021] 2. In the prior art, when coal blocks fall to the bifurcation of the hyperbolic pipe and decelerate, they often break due to impact. However, with the arc-shaped pressing plate and conical spring in this invention, the impact force of the falling coal blocks is effectively absorbed, thereby significantly reducing the breakage of coal blocks during the process of diverting to the arc surface of the hyperbolic pipe. Furthermore, by installing vibration damping blocks on the inner wall of the hyperbolic pipe at the bend, this invention can effectively reduce the impact of coal blocks on the inner wall of the hyperbolic pipe and reduce pipe wear.

[0022] The linkage design between the arc-shaped damping plate and the arc-shaped pressing plate in this invention not only enhances the buffering effect when coal blocks fall, but also disperses the impact force of falling coal blocks by setting the arc-shaped damping plate, reducing the direct impact of coal blocks on the hyperbolic pipe wall, thereby reducing pipe wall wear and extending the service life of the pipeline. Furthermore, the impact design between the arc-shaped damping plate and the pipe wall in this invention can effectively disturb the flow state of coal blocks, reducing the tendency of coal blocks to accumulate at the bifurcation of the hyperbolic pipe, thus greatly reducing the risk of blockage.

[0023] 3. In this invention, the impact between the arc-shaped extrusion block and the telescopic protrusion can prevent blockages in the hyperbolic tube during coal transportation. Furthermore, the connection between the airflow spray gun and the hyperbolic tube in this invention can accelerate the transportation efficiency of coal. At the same time, the conical dust-proof chamber at the bottom of the hyperbolic tube can reduce the diffusion of coal dust when the coal falls. The dust-proof screen can filter out large dust particles, and the dust collection port at the top of the dust-proof chamber can be directly connected to a dust purifier, thereby effectively reducing dust generation at the discharge port.

[0038] Example

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

[0040] To address the problems mentioned in the technical solutions, this application provides a hyperbolic coal chutes, including a hyperbolic pipe 1, an airflow spray gun device 11 installed on the outer surface of the hyperbolic pipe 1, a dust-proof chamber 12 fixedly connected to the lower surface of the hyperbolic pipe 1, a dust-proof net 13 installed on the inner wall of the dust-proof chamber 12, and also including an anti-blocking buffer warning mechanism 2 and an angle adjustment mechanism 3. The anti-blocking buffer warning mechanism 2 is disposed on the inner wall of the hyperbolic pipe 1, and the angle adjustment mechanism 3 is disposed in the middle of the hyperbolic pipe 1.

[0047] In the prior art, existing designs lack additional deceleration plates, buffer blocks, and other auxiliary structures, causing coal to still impact the coal receiving equipment at a high speed, resulting in equipment wear or increased coal breakage rate. Compared with the prior art, through the implementation of this embodiment, the linkage design between the arc-shaped vibration damping plate 23 and the arc-shaped pressing plate 21 not only enhances the buffering effect when the coal blocks fall, but also disperses the impact force of the falling coal blocks by setting the arc-shaped vibration damping plate 23, 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. Furthermore, the impact design between the arc-shaped vibration damping plate 23 and the pipe wall in this invention can effectively disturb the flow state of the coal blocks, reducing the tendency of coal blocks to accumulate at the bifurcation of the hyperbolic pipe 1, thereby greatly reducing the risk of blockage.

[0048] For further embodiments, please refer to Figures 1 to 7 As shown:

[0049] The angle adjustment mechanism 3 also includes a first arc-shaped telescopic plate 301. An adjustment groove is provided on the inner side of the hyperboloid near the middle of the hyperboloid of the hyperboloid 1, and the adjustment groove is connected to the hyperboloid 1 pipe.

The end of the second arc-shaped telescopic plate 302 away from the first arc-shaped telescopic plate 301 is rotatably connected to the other end of the adjustment groove. The outer surfaces of both sides of the first arc-shaped telescopic plate 301 and the second arc-shaped telescopic plate 302 are slidably connected in the adjustment groove opened in the hyperboloid 1.

[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] Vibration mechanism 4 is provided on the outer surface of both ends of the hyperbola 1. Vibration mechanism 4 includes drive teeth 41. The middle part of drive teeth 41 is rotatably connected to the outer surface of hyperbola 1. The tooth surface of drive teeth 41 meshes with gear turntable 42. Both ends of gear turntable 42 are rotatably connected to the outer surface of hyperbola 1. Vibration groove is opened on the inner surface of hyperbola 1 near gear turntable 42. Telescopic protrusions 43 are fixedly connected to the circumference of the inner surface of gear turntable 42.

[0052] A compression spring 44 is fitted 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. An arc-shaped extrusion block 45 is provided on the side of the telescopic protrusion 43 away from the compression spring 44. The arc-shaped extrusion block 45 is circumferentially fixedly connected to the vibration groove opened in the hyperbolic tube 1.

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

[0054] Compared to existing technologies where it is difficult to adjust the curvature of a pipeline after installation, this embodiment avoids the difficulty of adjusting the curvature after installation. Operators only need to flexibly adjust the rotation of the adjusting rod 31 according to the on-site operation requirements to adjust the curvature of the hyperbolic pipe 1. This not only allows the hyperbolic pipe 1 to be flexibly adjusted under different transportation conditions, increasing the flexibility and adaptability of pipeline transportation, but also reduces downtime for maintenance during production, further improving production efficiency.

[0055] The working principle of all the content in the above embodiments is as follows:

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

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

[0058] When using, such as Figure 3As shown, when a coal block falls into the bifurcation of the hyperbolic pipe 1 from the upper right side, some of the coal will fall onto the upper surface of the arc-shaped pressing plate 21 under the action of gravity. Since the arc-shaped pressing plate 21 is slidably connected in the control room 22, and its bottom is fixedly connected to the conical spring 24, the falling coal will cause the arc-shaped pressing plate 21 to slide downwards. At this time, the conical spring 24 begins to be compressed. Because arc-shaped damping plates 23 are rotatably connected to both sides of the bottom of the arc-shaped pressing plate 21, and these plates are rotatably connected to both sides of the control room 22, the downward sliding of the arc-shaped pressing plate 21 will cause the arc-shaped damping plates 23 to begin rotating. Since the arc-shaped damping plates 23 are symmetrically and evenly arranged in the control room 22, their functional principles are the same, so only those... Figure 3 The following description is provided by the indicated number group. As the arc-shaped pressing plate 21 slides downward, it will cause the arc-shaped damping plate 23 to start swinging upward in a clockwise direction. Since there are coal blocks continuously falling into the pipe, the arc-shaped damping plate 23 can reduce the direct impact of the coal blocks on the inner wall of the hyperbolic pipe 1. With the setting of the arc-shaped pressing plate 21 and the conical spring 24 in this invention, the impact force when the coal blocks fall is effectively absorbed, thereby significantly reducing the breakage of the coal blocks during the process of diverting to the arc surface of the hyperbolic pipe 1. In addition, by installing the damping block 303 on the inner wall of the hyperbolic pipe 1 at the bend, the impact of the coal blocks on the inner wall of the hyperbolic pipe 1 can be effectively reduced, and pipe wear can be reduced.

[0059] In this invention, the linkage design between the arc-shaped damping plate 23 and the arc-shaped pressing plate 21 not only enhances the buffering effect when the coal blocks fall, but also disperses the impact force of the falling coal blocks by setting the arc-shaped damping plate 23, 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. Furthermore, the impact design between the arc-shaped damping plate 23 and the pipe wall in this invention can effectively disturb the flow state of the coal blocks, reducing the tendency of coal blocks to accumulate at the bifurcation of the hyperbolic pipe 1, thereby greatly reducing the risk of blockage.

[0060] Furthermore, if the coal block is transported when it has a high viscosity, and if the coal block gets stuck on the curved pressing plate 21, the curved pressing plate 21 will be continuously pressed. At this time, because the present invention innovatively installs a pressure sensing device at the bottom of the conical spring 24, the inner wall of this sensing device is set to have a maximum pressing threshold time. Once the pressing time exceeds this preset threshold, the sensing device will respond quickly and send this emergency to the terminal controller through an electrical signal. After receiving the signal from the sensing device, the terminal controller will immediately take action and directly control the micro motor located on the hyperbolic tube 1 to start.

[0061] At this time, because the drive gear 41 is fixedly connected to the micro motor drive shaft, and the tooth surface of the drive gear 41 meshes with the tooth surface of the gear disk 42, the counterclockwise rotation of the drive gear 41 will drive the gear disk 42 to rotate clockwise and connect to the hyperboloid tube 1. Figure 7 As shown, the telescopic protrusion 43 is circumferentially fixedly connected to the gear turntable 42, and the arc-shaped extrusion block 45 is circumferentially fixedly connected in the vibration groove opened in the hyperbolic tube 1. Since the compression spring 44 is sleeved on the telescopic protrusion 43, when the gear turntable 42 rotates clockwise, it will drive the telescopic protrusion 43 to start extruding the inclined surface of the arc-shaped extrusion block 45. When the gear turntable 42 continues to rotate and causes the telescopic protrusion 43 to disengage from the extrusion block 45, the telescopic protrusion 43 will be driven to quickly extend and impact the inner wall of the hyperbolic tube 1 under the elastic action of the compression spring 44. At this time, the impact of the telescopic protrusion 43 will cause the coal blockage inside the hyperbolic tube 1 to vibrate. Excessive vibration can cause the blocked coal blocks to gradually fall off. In this invention, the impact between the arc-shaped extrusion block 45 and the telescopic protrusion 43 can prevent the blockage caused by the hyperbolic tube 1 during coal transportation. Moreover, the connection between the airflow spray gun device 11 and the hyperbolic tube 1 in this invention can accelerate the coal transportation efficiency. At the same time, the conical dust-proof chamber 12 set at the bottom of the hyperbolic tube 1 can reduce the diffusion of coal dust when the coal falls. Furthermore, the dust-proof net 13 can filter out large dust particles. The dust collection port at the top of the dust-proof chamber 12 can be directly connected to the dust purifier, thereby effectively reducing the dust generation at the discharge port.

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

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

[0064] As described above, when conveying different coal blocks, the operator can simultaneously adjust the adjusting rod 31 to adapt to the different speeds of the falling coal blocks. At this time, the operator can manually rotate the adjusting rod 31, such as... Figure 4As shown, because the adjusting rod 31 is fixedly connected to the middle 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 to start rotating 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 moving horizontally. Since the end of the T-shaped threaded sleeve 36 away from the threaded shaft 35 is rotatably connected to the first arc-shaped telescopic plate 301 and the first arc-shaped telescopic plate 301 respectively. Both ends of the first arc-shaped telescopic plate 301 and the second arc-shaped telescopic plate 302 are rotatably connected to the hyperbolic tube 1. At the same time, the first arc-shaped telescopic plate 301 is rotatably connected to the second arc-shaped telescopic plate 302. At this time, by changing the horizontal displacement of the T-shaped threaded sleeve 36, the first arc-shaped telescopic plate 301 and the second arc-shaped telescopic plate 302 can be driven to slide on the inner wall of the hyperbolic tube 1. Therefore, by rotating the adjusting rod 31, the operator can simultaneously adjust the position changes of the first arc-shaped telescopic plate 301 and the second arc-shaped telescopic plate 302 located on both sides of the hyperbolic tube 1.

[0065] Compared to existing technologies where it is difficult to adjust the curvature of a pipeline after installation, this invention avoids the difficulty of adjusting the curvature after installation. Operators only need to flexibly adjust the rotation of the adjusting rod 31 according to the on-site operation requirements to adjust the curvature of the hyperbolic pipe 1. This not only allows the hyperbolic pipe 1 to be flexibly adjusted under different transportation conditions, increasing the flexibility and adaptability of pipeline transportation, but also reduces downtime for maintenance during production, further improving production efficiency.
