[0053] like Figure 5 As shown, a flexible vibrating inclined filter 309 is mounted in the gap on the connecting pipe 301, and the flexible vibrating inclined filter 309 is fixedly connected to the inner wall of the ventilation main pipe 1. The front end bottom of the flexible vibrating inclined filter 309 is close to a slag collecting trough 2 with an open upper end and a closed lower end. The upper end of the slag collecting trough 2 is movably connected to the inner wall of the ventilation main pipe 1, and the lower end of the slag collecting trough 2 extends out of the ventilation main pipe 1; the flexible vibrating inclined filter 309 is located at the rear of the multiple groups of main fan blades 303.

[0054] like Figure 6As shown, the outer surface of the connecting pipe 301 is fixedly provided with a linkage fan blade 311, and a limit track 312 is fixedly installed between the linkage fan blade 311 and the inner wall of the ventilation main pipe 1, and a linkage ball 313 is arranged in the limit track 312, and the linkage ball 313 is movably connected with the linkage fan blade 311; an elastic vibration column 310 is fixedly installed on the rear end surface of the flexible vibration inclined filter 309, and the linkage fan blade 311 drives the flexible vibration inclined filter 309 to vibrate by moving the elastic vibration column 310 during the rotation process.

[0055] Specifically, in this embodiment, the provision of the fiber cloth fan blades 304 releases the pressure on the rubber water outlet 307 , so that water can flow toward the fiber cloth fan blades 304 through the rubber water outlet 307 .

[0056] Specifically in this embodiment, the atomizer 308 ensures the wetting of the inner wall of the connecting tube 301 and the humidity of the internal space, improves the adsorption force of the coal slag, and reduces the adsorption force of the coal slag on the inner wall of the connecting tube 301.

[0057] Specifically in this embodiment, the linkage blades 311 have no power themselves, and the linkage blades 311 are passively rotated under the drive of wind energy in the power element 4, thereby reducing the energy consumption of multiple components.

After passing 1.2m, the airflow hits the fiber cloth blade 304 of the middle group of blades. The curvature of the fiber cloth blade 304 of the middle group of blades is 1 / 28, and it has a stronger diffusion ability at the same speed, which can break up the dust-laden airflow and contact it with the atomized water droplets more quickly, and finally After passing 1.8 m, these air currents are gathered and recycled again by the main blades 303 in the right group of fan blades. A group of symmetrically arranged main blades 303 ensure the continuous input of wind force, and there are three groups of main blades 303 arranged in the connecting tube 301.

[0068] As a preferred solution of this embodiment, Figure 8 As shown, the motor 401 is provided with limit rings 402 on both sides of the left and right axes, and the limit rings 402 are also sleeved on the outer surface of the connecting pipe 301 with a gap.

[0069] Embodiment 2:

[0070] This embodiment provides a method for collecting coal slag in coal mining, and the collection method adopts the coal slag collection device in coal mining provided in the above embodiment 1.

[0071] The collection method includes the following steps:

[0072] Step 1: When coal mining begins, the power element 4 is started, and the motor 401 in the power element 4 causes the connecting pipe 301 in the coal collecting element 3 to rotate. The rotation of the connecting pipe 301 drives the main blades 303 and the fiber cloth blades 304 to rotate to generate wind power.

[0073] Step 2: The rotation of the connecting tube 301 drives the active bevel gear 403 to rotate, and through the driven bevel gear 404, the first flat gear 405, the first connecting rod 406, the second flat gear 409, the third connecting rod 410, the fourth connecting rod 411 and the fifth connecting rod 412, the horizontal rotation to the vertical rotation and then into the horizontal reciprocating motion.

[0074] Step three, the fifth connecting rod 412 drives the rubber ring 413 to push and pull back and forth in the water pipe. The fan-shaped elastic sheet 415 and the limiting cross 414 on the inner wall of the rubber ring 413 form a one-way valve for water flow in the water pipe 407 under the action of the driving force, pushing the water to flow through the one-way valve to the connecting pipe 301, and the water in the connecting pipe 301 is transported to the rubber water outlet 307 and the atomizer 308.

[0075] Step 4: The water in the connecting pipe 301 is continuously sprayed with water mist on the inner wall of the ventilation main pipe 1 through the atomizer 308. At the same time, driven by the incoming wind force, the fiber cloth fan blades 304 are deformed, and the rubber water outlet 307 is opened and water is supplied, so that the coal slag is mixed with water and adsorbed on the fiber cloth fan blades 304. The branch guide skeleton 306 on the fiber cloth fan blades 304 rotates the water coal slag to the inner wall of the ventilation main pipe 1.

[0076] Step 5: Driven by wind, the coal slag on the inner wall of the ventilation main 1 moves toward the flexible vibrating inclined filter 309, and the linkage fan blades 311 also rotate and work due to the wind and move the elastic vibrating column 310. The elastic vibrating column 310 allows the flexible vibrating inclined filter 309 to keep vibrating to avoid clogging. The vibration of the flexible vibrating inclined filter 309 causes the coal slag to enter the slag collecting tank 2 along the inclined surface.

[0077] Specifically, after the start of coal mining, the motor 401 is started, and the connecting pipe 301 starts to rotate along the axis driven by the motor 401. The active bevel gear 403 on the surface of the connecting pipe motor 401 rotates synchronously, and the driven bevel gear 404, the first flat gear 405, the first connecting rod 406, the second flat gear 409, the third connecting rod 410, the fourth connecting rod 411 and the fifth connecting rod 412 realize the horizontal rotation to the vertical rotation and then into the horizontal reciprocating motion. The fifth connecting rod 412 drives the rubber sleeve 413 to push and pull back and forth in the water pipe 407. The fan-shaped elastic sheet 415 and the limit cross 414 inside the rubber sleeve 413 become a one-way valve under the push-pull action, pushing the water from the water pipe 407 into the front end of the connecting pipe 301. After the motor 401 is started, the connecting pipe 301, the main fan blades 303 and the fiber cloth fan blades 304 rotate, generating a wind direction entering the connecting pipe 301. The fiber cloth fan blades 304 are deformed due to resistance. At this time, the deformation will also be released by the rubber water outlet 307 pressed by the edge of the fiber cloth fan blades 304. The water enters the surface of the fiber cloth fan blades 304 to soak the coal slag. The wetted coal slag moves toward the connecting pipe 301 along the direction of the branch guide skeleton 306. 1, and at the same time, after the motor 401 is started, the atomizer 308 continuously sprays water mist to the inside of the communication pipe 301 due to the force of the one-way valve assembly. Under the joint action of the power element 4 and the coal collecting element 3, the wet coal slag is continuously thrown to the inner wall of the ventilation main pipe 1, and driven by the wind, the wet coal slag will approach the flexible vibrating inclined filter screen 309 along the wind direction, and this wind force also ensures the rotation of the linkage fan blade 311. The rotation of the linkage fan blade 311 keeps moving the elastic vibration column 310, so that the flexible vibrating inclined filter screen 309 is continuously in a vibrating state. The coal slag attached to the surface of the flexible vibrating inclined filter screen 309 is also continuously guided into the slag collecting tank 2 under this action. The slag collecting tank 2 is drawn out for centralized treatment after the collection is completed.
