Description

Thermal power plants are usually divided into thermal power plants, nuclear power plants and gas-fired thermal power plants, etc. They play an important role in the global energy supply chain. The coal used by the boiler of the thermal power plant is conveyed from the raw coal bin or coal unloading trench to the top of the boiler house by the outdoor coal conveying belt, and then conveyed to different boilers by the internal coal conveying belt of the boiler house. When the coal falls from the outdoor coal conveying belt to the internal coal conveying belt, a large amount of dust is generated due to the difference between the two, which spreads everywhere, resulting in a poor environment in the boiler house and affecting the health of workers and the service life of equipment.

[0049] Further, the distance between the vortex-shaped support 302c-2 and the inner wall of the isolation screen 302b-1 is different at different positions due to the shape characteristics of the vortex-shaped support 302c-2, so that the vortex-shaped support 302c-2 is bonded to the isolation screen 302b-1 through multiple filling blocks, the fan blade 302c-4 is arranged to facilitate the rotation of the rotating shaft 302c-1 and the beating piece 302c-3 at the bottom of the rotating shaft 302c-1, and the fan blade 302c-4 is located in the isolation screen 302b-1. The beating piece 302c-3 is arranged to better drive the vortex-shaped support 302c-2 and the isolation screen 302b-1 to vibrate, so as to shake out the dust and large impurities located outside the isolation screen 302b-1.

[0050] The beating piece 302c-3 includes a bottom plate 302c-3a arranged at the bottom of the rotating shaft 302c-1, the bottom plate 302c-3a being fixedly connected to the center of the bottom of the rotating shaft 302c-1, a limiting box 302c-3b arranged on one side of the bottom plate 302c-3a, the bottom plate 302c-3a being fixedly connected to the limiting box 302c-3b, a stop block 302c-3c and a spring 302c-3d arranged in the limiting box 302c-3b, the inner wall of the limiting box 302c-3b being fixedly connected to the spring 302c-3d, a movable piece 302c-3e arranged on the spring 302c-3d, the spring 302c-3d being fixedly connected to the movable piece 302c-3e, a limiting support 302c-3f arranged on the movable piece 302c-3e, a beating wheel 302c-3g arranged on the limiting support 302c-3f, the limiting support 302c-3f being rotatably connected to the beating wheel 302c-3g, and the beating wheel 302c-3g being made of stainless steel, the limiting support 302c-3f being slidably connected to the limiting box 302c-3b, the beating wheel 302c-3g being matched with the vortex-shaped support 302c-2, the stop block 302c-3c being fixedly connected to the limiting box 302c-3b, and the outer wall of the beating wheel 302c-3g being matched with the outer wall of the vortex-shaped support 302c-2.

[0051] The bottom plate 302c-3a is arranged to better limit the limiting box 302c-3b and facilitate the rotation of the limiting box 302c-3b, the movable piece 302c-3e is fixedly connected to the limiting support 302c-3f and slidably connected to the limiting box 302c-3b, so as to limit the beating wheel 302c-3g.

[0052] The remaining structures are the same as those of Example 2

[0053] In use, the fan 201b drives the external air and the coal powder mixture to enter the inside of the dust guide mechanism 200 through the isolation mesh cover 302b-1 and the air guide cover 302a. The large particles, plastics and leaves in the air and the coal powder mixture are isolated outside the isolation mesh cover 302b-1. The air drives the fan blades 302c-4 and the shaft 302c-1 to rotate. The fan blades 302c-4 and the shaft 302c-1 drive the striker 302c-3 to rotate. In the process of rotating, the striker wheel 302c-3g rotates counterclockwise around the vortex support 302c-2. In the process of rotating, the striker wheel 302c-3g shrinks and squeezes the limiting support 302c-3f, the movable piece 302c-3e and the spring 302c-3d. The spring 302c-3d is squeezed to accumulate elastic potential energy. When the striker wheel 302c-3g rotates to the end point, the striker wheel 302c-3g resets under the action of the elastic potential energy of the spring 302c-3d and falls from the end point to the starting point of the vortex support 302c-2. Because the end point and the starting point of the vortex support 302c-2 have a distance, the impact generated drives the isolation mesh cover 302b-1 to vibrate. The vibration of the isolation mesh cover 302b-1 shakes the large particles, plastics and leaves outside the isolation mesh cover 302b-1, and the large particles, plastics and leaves fall into the conveyor belt under the action of gravity.
