Description

Technical Field

[0001] This utility model relates to the field of coal chutes, and in particular to a coal chute with a curve that prevents clogging and suppresses dust. Background Technology

[0002] A coal chute is a device used in material transfer to optimize material flow, reduce blockages and dust generation. It is widely used in coal mines, power plants, cement plants, coal preparation plants and other fields. It can guide the material flow into the coal chute at a smaller impact angle to ensure the collection and transportation of materials.

[0003] Chinese Patent No. CN220466481U discloses a method including a buffer hopper. A support plate is fixedly connected to the inner wall of the buffer hopper, a buffer column is fixedly connected to the top of the support plate, and a support plate is fixedly connected to the top of the buffer column. After being buffered by the two support plates, the coal continues to slide downwards. A wear-resistant guide plate is placed to prevent the coal from impacting the inner wall of the buffer hopper when it falls from the support plate below. The impact force of the coal entering the coal chute is smaller, thereby reducing the wear on the coal chute and avoiding damage to the coal chute caused by large impact force, which would lead to deformation of the coal chute and improve the service life of the coal chute.

[0004] Based on the above, the inventor believes that when coal chutes are in use, coal dust easily adheres to the inner wall. If not treated in time, it can easily clog the pipes. At the same time, dust is easily generated after coal is discharged from the mine, which is detrimental to the physical and mental health of workers. Utility Model Content

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] This utility model embodiment specifically provides an anti-clogging and dust-suppressing curved coal drop pipe. Please refer to... Figure 1 It includes a coal chute 1, a guide assembly 2, a dredging assembly 3, and a dust collection assembly 4.

[0035] The top of the coal chute 1 is fixedly equipped with a feed hopper 11. Coal is fed into the coal chute 1 through the feed hopper 11 and then onto the external conveyor belt. The guide component 2 is fixedly installed on the outside of the coal chute 1. The unblocking component 3 can move along the guide component 2 to knock off the coal dust adhering to the inner wall of the coal chute 1. The dust collection component 4 is fixedly installed at the bottom of the coal chute 1 to absorb the dust generated during coal churn.

[0036] Specifically, please refer to Figure 2 The guide component 2 is installed at the bottom of the coal chute 1. Since the coal falls into the coal chute 1 and has a lot of contact with the bottom surface, it is easy to adhere and accumulate dust. The guide component 2 includes a guide frame 21, a guide rail 22 and a locking tooth 23. The guide frame 21 is fixedly installed on the surface of the coal chute 1, the guide rail 22 is opened in the guide frame 21, and the locking tooth 23 is fixedly set at intervals along the length of the guide rail 22 so as to provide movement support for the unblocking component 3 through the guide rail 22 and the locking tooth 23.

[0037] The bottom surface of the guide rail 22 is parallel to the surface of the coal drop pipe 1, and the bottom end of the locking tooth 23 is fixed to the guide rail 22 so that the locking tooth 23 can extend along the length of the guide rail 22, so that the unblocking component 3 can move stably along the guide rail 22 to knock off the coal ash on the bottom surface inside the coal drop pipe 1.

[0038] Furthermore, the unblocking component 3 includes a movable component 31 and an installation chamber 32. The movable component 31 slides along the guide rail 22, and the left and right ends of the installation chamber 32 are rotatably connected to the movable component 31, so that the installation chamber 32 can move along the bottom end of the curved coal drop pipe 1 through the movable component 31, thereby improving the knocking effect on the sticky coal and avoiding blockage.

[0039] Specifically, please refer to Figure 3 The moving component 31 includes a first gear 311 and a slide 312. The outer side of the first gear 311 meshes with the locking teeth 23. The slide 312 is coaxially fixed on the left and right sides of the first gear 311. The outer side of the guide frame 21 slides in contact with the slide 312, so that the adjacent surfaces of the two slides 312 can contact and abut with the guide frame 21, thereby enabling the first gear 311 to move stably along the guide rail 22 when it rotates.

[0040] The unblocking component 3 also includes a knocking component and a driving component. The knocking component slides in contact with the outer surface of the coal chutes 1 to knock off the coal stuck to the bottom surface of the coal chutes 1. The driving component is connected to the moving component 31 to drive the moving component 31 to operate.

[0041] During implementation, the surface of the coal chute 1 is fixed with first protrusions 5 at intervals, and the installation chamber 32 is provided with a sliding opening 321. The inner wall of the sliding opening 321 slides along the guide rod 6, and the top of the guide rod 6 is fixed to the feed hopper 11, so that when the installation chamber 32 is displaced, it can move stably along the guide rod 6.

[0042] Specifically, please refer to Figure 4 The ash-knocking assembly includes a second protrusion 331, a timing frame 332, and a striking column 333. The second protrusion 331 and the striking column 333 are slidably installed on the side of the installation chamber 32 near the surface of the coal drop pipe 1. The top of the second protrusion 331 is fixed to the striking column 333 by the timing frame 332. A spring 334 is fixedly installed between the bottom of the timing frame 332 and the installation chamber 32. A rubber pad 335 is fixedly installed at the bottom of the striking column 333. The bottom of the rubber pad 335 is in contact with the coal drop pipe 1.

[0043] The first protrusion 5 and the second protrusion 331 have the same structure and are arranged symmetrically. The bottom surface of the second protrusion 331 slides in contact with the coal drop pipe 1. When the installation chamber 32 moves up or down on the surface of the coal drop pipe 1 through the moving component 31, the slope surface of the second protrusion 331 slides onto the slope surface of the first protrusion 5 and is squeezed and retracted into the inner wall of the installation chamber 32. This causes the second protrusion 311 to drive the striking column 33 to retract into the installation chamber 2 synchronously through the synchronous frame 332. After the second protrusion 331 and the first protrusion 5 are misaligned, the second protrusion 331 and the striking column 333 are reset by the elastic force of the spring 334 to strike the surface of the coal drop pipe 1 and knock the coal ash adhering to the bottom surface of the inside of the coal drop pipe 1, which helps to clean the adhering coal ash and reduce blockage.

[0044] Among them, a shaft 313 is coaxially fixed on the outer side of the slide plate 312. The outer side of the shaft 313 is rotatably installed in the mounting chamber 32. After the shaft 313 passes through the mounting chamber 32, a second gear 314 is coaxially fixed thereon, so that when the first gear 311 rotates, it can rotate synchronously with the second gear 314.

[0045] Furthermore, the drive assembly includes a third gear 341, a synchronizing rod 342, a fourth gear 343, a motor 344, and a mounting plate 345. The outer side of the third gear 341 is engaged with the second gear 314, and the outer side of the third gear 341 is coaxially fixed with the synchronizing rod 342 so that the second gears 314 on both sides are driven synchronously through the third gear 341 and the synchronizing rod 342, thereby driving the two first gears 311 to rotate synchronously. The third gear 341 is rotatably mounted inside the mounting chamber 2.

[0046] In practice, the fourth gear 343 is rotatably installed inside the mounting chamber 32, and the outer side of the fourth gear 343 is meshed with the third gear 341. The fourth gear 343 is coaxially fixed with the output shaft of the motor 344. The outer side of the motor 344 is fixed to the mounting chamber 32 through the mounting plate 345, so that the motor 344 drives the fourth gear 343 to rotate. Then, the other connected gears drive the first gear 311 to rotate in the forward or reverse direction through transmission engagement, thereby driving the mounting chamber 32 to move.

[0047] Further, please refer to Figure 5The dust collection assembly 4 includes a frame 41, a curtain 42, a suction pipe 43, a suction chamber 44, and an opening 45. The frame 41 is fixed to the bottom outer side of the coal drop pipe 1. The top of the curtain 42 is fixed to the frame 41. The curtain 42 is made of flexible rubber and its bottom surface is in contact with the surface of the conveyor belt. Thus, when coal is dropped, the curtain 42 can disperse and limit the dust. The suction pipe 43 is fixed to the outside of the frame 41 and is used to connect to external dust collection equipment. The suction chamber 44 is opened inside the frame 41 and is connected to the suction pipe 43. The opening 45 is opened at the bottom of the suction chamber 44. When coal is dropped, dust is sucked into the suction chamber 44 through the opening 45 and then sucked into the external dust collection equipment for processing by the suction pipe 43.

[0048] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
