Description
DESCRIPTION Underground Crushing and Sieving Coal Gangue Separator Technical Field
[0001] The disclosure relates to the field of coal gangue separation, and in particular, to an underground crushing and sieving coal gangue separator. Background
[0002] Coal gangue separators can realize coal gangue separation under mines and directly fill gangue under mines, which can greatly save transportation costs and also reduce pollution. The existing underground crushing and sieving coal gangue separators utilize a hardness difference between coal and gangue to selectively crush coal, so as to realize the separation of coal and gangue. However, due to sludge attached to the surface of coal gangue just mined, if the crushing strength is insufficient, it is difficult to crush some big pieces of coal with thick sludge attached. If the coal is to be completely crushed, it is necessary to increase the crushing strength, which will also cause a greater crushing effect on gangue, resulting in insufficient separation accuracy and poor separation effect.
Summary
[0003] In view of the problems in the prior art, the disclosure provides an underground crushing and sieving coal gangue separator.

[0031] When the underground crushing and sieving coal gangue separator is in use, the first motor 22 and the second motor 26 are started.
The first motor 22 drives the hollow feeding pipe 211 in the mud-water separator 21 to rotate and the conveying propeller 213 to rotate.
The second motor 26 drives the centrifugal pump 24. The liquid adding pipe 27 is connected to an external water source to deliver clear water.
[0032] The third motor 34 is started to drive the first shaft rod 33 to rotate anticlockwise and the first crushing hammer 31 to rotate anticlockwise.
The first rotating wheel 331 on the first shaft rod 33 drives the eighth rotating wheel 619 to rotate through the fourth transmission belt 620. The third shaft rod 618 drives the driving wheel 616 to rotate.
An end of the linkage pushing rod 617 movably mounted at a centrifugal part of the wheel surface of the driving wheel 616 performs a circular motion, while the linear sliding rod 613 movably connected to the other end of the linkage pushing rod 617 can only perform a linear motion.
Therefore, during the rotation of the driving wheel 616, the linkage pushing rod 617 drives the linear sliding rod 613 to perform a linear reciprocating motion.
Since the linkage clamping bolt 614 at the other end of the linear sliding rod 613 is clamped in the linkage clamping groove 612 at the upper end of the linkage rotating rod 610, when the linear sliding rod 613 performs a linear reciprocating motion, the linkage rotating rod 610 is also driven to perform a repeated swinging motion using the fulcrum bolt rod 611 as an axis, a connecting end of the transition rod 69 and the linkage rotating rod 610 performs a reciprocating swinging motion, and a lower end of the transition rod 69 is connected to the bolt rod 68 on the connecting plate 65, so that a high end of the vibrating sieve plate 61 is driven to vibrate up and down, i.e. the vibrating sieve plate 61 continuously vibrates using the supporting shaft 64 as a fulcrum.
The fourth motor 38 is started to drive the second shaft rod 37 to rotate clockwise.
The second crushing hammer 36 and the second rotating wheel 371 rotate clockwise.
The second rotating wheel 371 drives the coaxial third rotating wheel 411 and the first gear 41 to rotate clockwise through the first transmission belt 412. The second gear 42 and the third gear 43 meshing with the first gear 41 rotate anticlockwise.
The fifth rotating wheel 431 on the third gear 43 drives the seventh rotating wheel 641 to rotate anticlockwise.
The supporting shaft 64 on the vibrating sieve plate 61 is driven to rotate anticlockwise.
The synchronizing gears 66 on the supporting shaft 64 drive the synchronizing gears 66 on the rollers 63 to rotate through the chain 67, thereby driving the rollers 63 to rotate anticlockwise.
The fourth rotating wheel 421 on the second gear 42 drives the sixth rotating wheel 56 to rotate through the second transmission belt 422. The third connecting rod 55 performs a continuous and stable circular motion with the sixth rotating wheel 56. An end of the second connecting rod 54 connected to a front end of the third connecting rod 55 performs a circular motion, and the other end is limited by the first connecting rod 53. Therefore, a connecting end of the second connecting rod 54 and the first connecting rod 53 performs an obtuse angle reciprocating rotation using the rotating shaft 52 as an axis, and then drives the pushing plate 51 to repeatedly swing, so as to push materials in the feeding slide 14 and promote the materials to slide.
Coal gangue raw materials are poured into the feeding slide 14 through the feeding hopper 13. The pushing plate 51 performs a repeated swinging motion to push the coal gangue raw materials to slide down in the feeding slide 14. Clear water input in the liquid adding pipe 27 enters the water passage pipeline 28, and is sprayed onto the coal gangue raw materials through the spray heads 291 to clean soil on the surface of the coal gangue raw materials.
Muddy water flows into the muddy water groove 16 through the fine sieve 15, and enters the hollow feeding pipe 211 in the mud-water separator 21 through the drainage pipe 17. The hollow feeding pipe 211 is driven by the first motor 22 to rotate.
The muddy water enters the sleeve 215 via the discharge port 214. Then solid particles in the muddy water are conveyed to the mud discharge port 216 via the conveying action of the conveying propeller 213 and discharged, while liquid flows to the water discharge port 217 and flows into the filter tank 23. The liquid which has undergone solid-liquid separation is further filtered through the filter tank 23, and micro particles therein are adsorbed and filtered.
Then filtrate is conveyed via the centrifugal pump 24, enters the liquid adding pipe 27 through the water delivery pipe 25, is mixed with the clear water in the liquid adding pipe 27 and enters the water passage pipeline 28. The mixed liquid is sprayed into the feeding slide 14 through the spray heads 291, coal and gangue therein are washed, and muddy water formed penetrates through the fine sieve 15 into the muddy water groove 16, is uniformly drained into the mud-water separator 21 via the drainage pipe 17, and is then subjected to cycling filtration, so as to realize the recycling of water resources and save water.
The cleaned coal gangue enters the crushing groove 19. The first crushing hammer 31 performs first crushing on a large piece of coal, and impacts coal gangue on the impact toothed plate 35 to perform impact crushing.
Then the coal gangue falls to the second crushing hammer 36 to perform second crushing on the coal, so as to achieve multiple crushing and ensure complete crushing.
The crushed coal gangue falls onto the vibrating sieve plate 61, and the rollers 63 on the vibrating sieve plate 61 rotate anticlockwise, so as to promote the coal gangue to slide down.
Meanwhile, the vibrating sieve plate 61 performs continuous vibration with the supporting shaft 64 at the bottom end as a fulcrum, so as to ensure that the coal gangue can slide down.
Meanwhile, a large piece of gangue does not block at a gap between the rollers 63. During the downward sliding of the crushed coal and gangue, small pieces of coal and gangue fall into the coal slide 111 through the gap between the rollers 63 to be discharged.
The bottom of the coal slide 111 collects mixtures of the crushed small pieces of coal and small pieces of gangue, and the mixtures are transported out of a mine.
The large pieces of gangue slide down along the vibrating sieve plate 61 into the gangue slide 112 to be discharged for laying raw materials on roads under the mine.
