Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc. indicating the orientation or position relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0030] Please refer to Figure 1 、 Figure 2 , the present invention provides a suspended-section screen-bottom raw coal recoverable coal-water separation transfer machine, in which a water discharge trough 100 and a convex groove 200 are sequentially arranged in the suspended section of the transfer machine; Among them, the water discharge trough 100 includes a trough body 01, a power part 02, and a cross-screen assembly 03; a material leakage hole 11 is formed in the middle plate inside the trough body 01, and a square hole 12 is formed in the side plate of the trough body 01. The cross-screen assembly 03 is inserted into the trough body 01 along the square hole 12, and the upper end of the cross-screen assembly 03 is lower than the upper end of the material leakage hole 11; the cross-screen assembly 03 replaces part of the middle plate. A wear-resistant slide bar 13 is arranged at the upper end of the cross-screen assembly 03. The wear-resistant slide bar 13 can be stuck into the middle plate of the trough body 01, and the wear-resistant slide bar 13 is flush with the middle plate of the trough body 01. There are two wear-resistant slide bars 13, and the two wear-resistant slide bars 13 are arranged side by side. The center distance between the two wear-resistant slide bars 13 is the same as the center distance of the chain, which can provide support for the operation of the chain and prevent the chain from sagging due to its own gravity during operation and interfering with the movement of the cross-screen assembly 03. Secondly, after the wear-resistant slide bar 13 is installed on the middle plate of the trough body 01, it can limit the left and right movement of the cross-screen assembly 03 in the trough body 01. And for facilitating the installation of the cross-screen assembly 03 into the square hole 12, a slideway 14 is arranged in the square hole 12.

[0031] A feeding mechanism 04 communicating with the lower chain path of the convex groove 200 is arranged below the convex groove 200. The outlet end of the feeding mechanism 04 is communicated with a sorting and transporting mechanism 05 for separating and transporting solid raw coal and water. The outlet end of the sorting and transporting mechanism 05 is communicated with a transfer machine for recycling the screened raw coal to the transfer machine. The coal-water mixture screened by the cross-screen assembly 03 is transported to the lower chain path of the convex groove 200 through the lower chain path of the trough body 01 and falls into the feeding mechanism 04. Then, the coal-water mixture is sent into the sorting and transporting mechanism 05 by the feeding mechanism 04. After the solid raw coal is sorted and recycled by the sorting and transporting mechanism 05, it is transported to the transfer machine, so as to realize the automatic recovery of raw coal, and the water separated from the mixture is discharged from the sorting and transporting mechanism 05; in the whole process, manual cleaning is not required, manual labor is reduced, and continuous operation is carried out, avoiding the shutdown of the working face equipment caused by manual cleaning of raw coal.

[0032] Please refer to Figures 3 to 8 , in an embodiment, the cross-screen assembly 03 includes a base 31, a screen shaft 32, and a pressing block 33; the pressing blocks 33 are fixedly arranged opposite to each other on the base 31. The screen shafts 32 are evenly distributed at equal intervals along the arrangement direction of the wear-resistant slide bars 13, and the two ends of the screen shaft 32 are rotationally connected to the pressing blocks 33. A notch for placing the wear-resistant slide bar 13 is left on the screen shaft 32, so that the screen shaft 32 does not interfere with the movement of the wear-resistant slide bar 13 when rotating.

[0033] Among them, the screening shaft 32 includes a rotating shaft 321 and a disc screening sheet 322; both ends of the rotating shaft 321 are rotatably connected to the pressing block 33. The disc screening sheets 322 are evenly distributed at equal intervals along the axial direction of the rotating shaft 321, and the disc screening sheets 322 on two adjacent rotating shafts 321 are arranged staggeredly, forming many narrow-width and relatively long-slit slits for water leakage. The rotation of the disc screening sheet 322 can loosen the raw coal at the bottom layer, facilitating the downward penetration of the water gushing out from the pores of the raw coal through the screen; the width of the slits formed between the screening sheets is relatively narrow, restricting the raw coal with a size larger than the slit width from entering the lower chain path, which can reduce the recovery amount of the raw coal under the screen. Secondly, the adjacent disc screening sheets 322 can clean the adhered coal slime from each other during rotation, ensuring the smoothness of the water leakage holes.

[0034] Of course, the disc screening sheet 322 and the rotating shaft 321 can also be eccentrically installed. In this installation method, the maximum limit movement trajectory of the disc screening sheet 322 does not interfere with the movement of the adjacent rotating shaft 321.

[0035] In one implementation, the power unit 02 includes a motor 21 and a multi-axis output reducer 22; the multi-axis output reducer 22 is installed on the base 31, and the input end of the multi-axis output reducer 22 is connected to the motor 21, and the output end of the multi-axis output reducer 22 is correspondingly connected to each screening shaft 32.

[0036] Among them, the multi-axis output reducer 22 includes a housing 221, an input gear shaft 222, and an output gear shaft 223; the housing 221 is installed on the base 31, and the output gear shafts 223 are sequentially rotatably installed in the housing 221, making the axes of two adjacent output gear shafts 223 parallel, and two adjacent output gear shafts 223 are meshed with each other. The input gear shaft 222 is rotatably installed at the middle position of the housing 221, and the input gear shaft 222 is meshed with the output gear shafts 223 on the left and right sides.

[0037] Of course, the gear teeth numbers of the corresponding gears of two adjacent output gear shafts 223 are different, and the gear teeth numbers of the corresponding gears of the spaced output gear shafts 223 are the same.

[0038] When the "water coal" passes through, the power of the motor 21 is transmitted to the output gear shaft 223 through the input gear shaft 222. Since the number of teeth of the gears corresponding to the adjacent output gear shafts 223 is different, and the number of teeth of the gears corresponding to the spaced output gear shafts 223 is the same, at this time, the rotational speeds transmitted to the adjacent rotating shafts 321 corresponding to the adjacent output gear shafts 223 are different, while the rotational speeds of the spaced rotating shafts 321 are the same. At the same time, the disk sieve 322 and the rotating shaft 321 are eccentrically installed, which will cause the disk sieve 322 to form irregular fluctuations up and down. The sizes of the water leakage holes formed between the adjacent disk sieves 322 also change irregularly at all times. Using this dynamic irregular fluctuation can loosen the underlying materials, facilitate water penetration, adopt an irregular fluctuation sieve surface, have better dehydration ability, require a shorter length of the drain trough, can effectively shorten the suspended section length of the coal-water separation transfer machine, avoid the collapse of the waist caused by too long suspended section of the transfer machine, and reduce the no-load power and manufacturing and use costs of the transfer machine. Secondly, because the disk sieve 322 is eccentrically installed, when the disk sieve 322 rotates, it can impact the disk sieves 322 on the adjacent rotating shafts 321. Using the disk sieve 322 to drive the coal-water mixture to form a rapid scour between the adjacent disk sieves 322 on the same rotating shaft 321, so as to be able to clean the coal slime attached to the disk sieve 322 more efficiently; and the impact formed by the disk sieve 322 can also hammer the underlying materials, promote the loosening of the deposited materials, prevent material accumulation between the disk sieve 322 and the adjacent rotating shaft 321, and facilitate water leakage.

[0039] Please refer to Figure 9 、 Figure 10 In one embodiment, the feeding mechanism 04 includes a flange 41, a star-shaped feeding claw 42, and a reduction motor 43; the flange 41 is connected and installed at the bottom of the lower chain path of the convex groove 200. A discharge port 411 is provided on one side of the bottom of the flange 41. The star-shaped feeding claw 42 is rotatably installed in the flange 41, and the bottom of the star-shaped feeding claw 42 is attached to the bottom of the flange 41. The reduction motor 43 is installed outside the flange 41 and the output end is connected to the input end of the star-shaped feeding claw 42 to drive the star-shaped feeding claw 42 to rotate circumferentially. During the rotation of the star-shaped feeding claw 42, relying on the rotation of the star-shaped feeding claw 42, the coal-water mixture will be dialed to the periphery of the flange 41. Under the continuous rotation of the star-shaped feeding claw 42, the coal-water mixture forms an eddy current in the flange 41 in the same direction as the rotation direction of the star-shaped feeding claw 42. Thus, it can use the water flow and the feeding action of the star-shaped feeding claw 42 to scour and feed the solid coal at the same time, and can quickly discharge the coal-water mixture from the discharge port 411.

[0040] Specifically, the star-shaped coal discharging claw 42 includes a disk body 421, a coal discharging plate 422, and a substrate 423. The disk body 421 is rotatably installed in the flange 41. The input end of the disk body 421 is connected to the input end of the reduction motor 43. The substrate 423 is fixed on the outer wall of the disk body 421 and is circumferentially distributed along the outer wall of the disk body 421. The substrate 423 is in contact with the bottom of the flange 41. When the substrate 423 rotates with the disk body 421, the coal slime adhering to the bottom of the flange 41 can be scraped up by the substrate 423 and is discharged under the scouring action of water flow. The coal discharging plate 422 is fixed on the outer wall of the disk body 421, and the lower end of the coal discharging plate 422 is fixed on the substrate 423.

[0041] Among them, the coal discharging plate 422 is arc-shaped, and the side where the coal discharging plate 422 bulges outwards contacts the material. After the coal discharging plate 422 contacts the solid coal, since the side where the coal discharging plate 422 bulges outwards is arc-shaped, on the one hand, the rotation resistance can be reduced. On the other hand, through the action of the coal discharging plate 422 and the action of the centrifugal force of the water flow, the solid coal can be dispersed along the coal discharging plate 422 to the periphery of the flange 41, and the coal-water mixture can form a vortex, so that the coal-water mixture can be discharged from the discharge port 411 under the guidance of the coal discharging plate 422.

[0042] Please refer to Figure 11 , in an embodiment, the sorting and transfer mechanism 05 includes a box body 51, a power shaft 52, a spiral blade 53, and a driving part 54. The inlet end of the box body 51 is communicated with the discharge port 411 on the flange 41. The power shaft 52 is rotatably installed in the box body 51 along the length direction of the box body 51. The spiral blade 53 is fixedly installed on the outer wall of the power shaft 52 along the axis direction of the power shaft 52. There is a gap between the spiral blade 53 and the outer wall of the power shaft 52. When the spiral blade 53 rotates, the coal-water mixture will be dispersed towards the inner wall of the box body 51, and the solid coal will be conveyed out through the spiral blade 53, while the remaining water will flow to the low point of the box body 51 through the gap between the spiral blade 53 and the outer wall of the power shaft 52, so as to separate the solid coal from the water. The driving part 54 is installed outside the box body 51, and the input end of the driving part 54 is connected to the input end of the power shaft 52.

[0043] Among them, in order to facilitate the discharge of the water in the box body 51, an overflow hole 511 is provided on the side of the box body 51. Of course, a mounting flange 512 can also be provided on the box body 51, and the mounting flange 512 can be externally connected to a water pump to quickly discharge the separated water through the water pump.

[0044] Specifically, a guide trough 55 communicating with the transfer machine is provided at the outlet end of the box body 51, so that the screened solid coal can be recovered to the transfer machine.

[0045] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of rights of the present invention cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the invention.
