Description

Technical Field

[0001] The invention relates to the technical field of coal washing mechanisms, in particular to a clean coal washing mechanism. Background Art

[0002] Coal washing machine is a mechanical equipment used for washing and grading coal. Its main function is to remove impurities (such as mud, stones, etc.) in raw coal by mechanical means, so as to improve the quality of coal. Coal washing machine is widely used in coal processing industry and is one of the important equipment in coal production process. Raw coal contains a lot of mud and other impurities. Direct use will reduce the combustion efficiency of coal and increase the ash content. Coal washing can effectively improve the quality of coal and enhance its market competitiveness. By removing impurities in coal, harmful gases and dust generated during combustion can be reduced, reducing environmental pollution.

[0003] However, the existing coal washing mechanism still has some shortcomings. For example, after the existing coal washing mechanism completes the coal cleaning, the coal usually needs to be transported to another equipment or area for subsequent processing (such as drying, grading, etc.), which not only increases the processing time and work complexity, but also during the transportation process, the coal and peat are easy to fall or scatter on the ground, causing site pollution, which not only increases the cleaning workload but also causes waste of resources.

[0036] It should be noted that the present invention is a clean coal washing mechanism, and each component is a universal standard component or a component known to those skilled in the art, and its structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0037] Working principle: Step 1: When the coal needs to be cleaned, the coal is put into the feeding port 102, and then the coal begins to flow through the blocking of the legs 103, so that the coal falls evenly on the two sets of vibrating screen plates 202, and then the cam 222 is driven to rotate by the output motor 201. When the cam 222 rotates, the outer wall of the cam 222 contacts the bottom of the second guide plate 210, which can drive the vibrating screen plate 202 to vibrate up and down; Step 2: When too much coal falls on the top of the vibrating screen plate 202, the vibrating screen plate 202 will press the upper connecting rod 213 to drive the slider 212 to move to both sides. At this time, the vibrating screen plate 202 is pressed by the coal to rotate downward, and the contact area with the cam 222 will be larger, which can bring a larger vibration to the vibrating screen plate 202, so that the coal accumulated on the vibrating screen plate 202 can be quickly dispersed, and the coal ash on the coal can be washed off by the flushing of several groups of fixed nozzles 204; Step 3: When the vibration screen plate 202 obtains a larger vibration amplitude, the first rotating shaft 206 will be driven by the vibration screen plate 202 to swing. When the first rotating shaft 206 swings, it will drive the first half gear 218 and the second half gear 219 to swing together. The first half gear 218 and the second half gear 219 are meshed with the full gear 217, which can drive the full gear 217 to rotate back and forth. The first moving nozzle 205 and the second moving nozzle 207 are fixedly connected inside the two groups of full gears 217, respectively, and can drive the first moving nozzle 205 and the second moving nozzle 207 to swing, so that the flushing angle is increased, so that the coal is fully washed clean; Step 4: While the coal is being washed, the impurities and coal ash will fall from the holes of the vibrating screen plate 202 to the top of the second guide plate 210 driven by the water flow, and then flow through the diversion block 220, and finally flow into the diversion pipe 221, and fall on the top of the first guide plate 209. The coal that has been washed and screened for the first time will fall on the top of the filter plate 208, and will be washed twice by the swinging second moving nozzle 207, and finally fall into the inside of the dewatering barrel 309 through the convergence block 211, while the washed coal ash and impurities fall on the top of the first guide plate 209, and fall on the top of the dewatering screen plate 306 along with the water flow; Step 5: When the vibrating screen plate 202 vibrates, the two sets of sliders 212 will make a linear reciprocating motion inside the supporting platform 203, and the rack 216 at the bottom of the slider 212 will mesh with the limit block 321 to drive the ratchet gear 312 to rotate. When the two sets of racks 216 move inward at the same time, the claw 335 inside the ratchet gear 312 will not limit the ratchet gear 312. When the two sets of racks 216 move outward at the same time, the claw 335 will limit the ratchet inside the ratchet gear 312. At this time, the rotation of the ratchet gear 312 will be restricted by the claw 335, and the fixed sleeve 334 will rotate together. The fixed sleeve 334 is fixedly connected to the dewatering barrel 309 through the fixed rod 324, and the dewatering barrel 309 will be driven to rotate, and the coal inside the dewatering barrel 309 can be cleaned at this time; Step six, when the coal inside the dewatering barrel 309 accumulates to a certain extent, the dewatering barrel 309 will press the top rod 314 and the return spring 315 to descend, and when the top rod 314 moves toward the inner cavity 319, the oil inside the inner cavity 319 will flow through the seepage hole 318, generating a damping feeling, causing it to slowly descend, and while the dewatering barrel 309 descends, the lower connecting rod 313 above the turntable 301 will move outward with the four groups of arc plates 325 below the dewatering barrel 309, and then a gap will open at the bottom of the dewatering barrel 309, and the dehydrated coal will fall from the bottom of the dewatering barrel 309 and pass through the bottom discharge hole opened at the bottom of the outer shell 101 The coal at the bottom is discharged from the outlet 112. When the coal at the bottom is discharged, the dewatering bucket 309 rises under the drive of the return spring 315, so that the coal at the bottom that has been dehydrated for a long time is released, and the coal at the top falls to the bottom. When the dewatering bucket 309 falls, the first baffle 310 in the middle of the dewatering bucket 309 will press the telescopic rod 332 to fall together. A nylon belt 330 is fixedly connected to one side of the rotating shaft 322. The other end of the nylon belt 330 passes through the third rotating shaft 329 and is fixedly connected to the bottom of the second baffle 328. When the rotating shaft 322 descends, it will bring the second baffle 328 up through the nylon belt 330 to block the coal falling from the filter plate 208. Step 7: When the dehydration barrel 309 rotates, the turntable 301 can rotate accordingly, and the central shaft 305 fixedly connected to the turntable 301 can rotate accordingly. The rotation of the central shaft 305 will drive one of the auxiliary shafts 304 to rotate through the second V-belt 339. The rotation of the auxiliary shaft 304 will drive the second rotating shaft 303 to rotate through the first V-belt 302. The second rotating shaft 303 is fixedly connected to the rotating shaft 322. The rotation of the second rotating shaft 303 will drive the rotating shaft 322 to rotate together. The movement will cause the limit block 321 inside the sliding sleeve 307 to slide up and down along the shape of the first sliding groove 323. The rubber pad 320 above the sliding sleeve 307 is fixedly connected to the bottom of the dewatering screen plate 306, which can make the dewatering screen plate 306 vibrate. Due to the high weave count of the dewatering screen plate 306, impurities are gradually separated from the fly ash and liquid. The liquid falls through the aperture of the screen, while the impurities and fly ash are retained on the screen, so that the discharged peat and coal are fully dehydrated, which is convenient for transportation and cleaning, and makes the workplace drier and cleaner.
