Description

Technical Field

[0001] This invention relates to the field of coal slime processing technology, and in particular to a coal slime drying and mixing device for coal slime reprocessing and its usage method. Background Technology

[0002] Coal slime is a waste product consisting of a mixture of coal powder and water produced during coal washing. Although coal slime can be recycled, the recycled coal slime is highly viscous, has a high ash content, strong water retention, and high moisture content, making it difficult to achieve industrial applications. It is mainly sold for civilian use. With market development and increased demand for coal, the production of coal slime has increased significantly, while the demand for coal slime fuel for civilian use has gradually decreased. This has resulted in a large amount of coal slime not being properly disposed of. Long-term stockpiling occupies space and affects production. Moreover, after drying, it is blown away by the wind, and the moisture contained in the sorting agents in the coal slime seeps into the ground, making the coal slime unusable. This not only wastes resources but also pollutes the environment.

[0003] Currently, coal slime after coal washing is generally filtered by a filter press before being mixed with clean coal. However, the filter cake after filtration still contains a lot of moisture. The coal slime filter cake is sticky, causing the coal slime to adhere to the feeding surface, which can lead to blockage or accumulation of the coal slime on the feeding surface. This severely affects the smoothness of coal slime feeding. Furthermore, when coal slime is mixed with clean coal, it is easy for the coal slime to clump together. At the same time, the coal slime is mixed with clean coal in pieces, resulting in poor mixing effect between the coal slime and clean coal, which does not meet the homogenization requirements of the product. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a coal slime drying and mixing device and its usage method for coal slime reprocessing.

The protective shell includes a main shell fixedly connected to the top plate and a movable shell rotatably connected to the bottom of the main shell via a pin. A torsion spring for driving the movable shell to reset and rotate is sleeved on the pin.

[0017] Preferably, the U-shaped feeding frame has a discharge port at its end, and a rotating rod is provided at the discharge port.

[0019] Preferably, a flexible sealing element is provided between the top plate and the U-shaped conveyor frame, and a flexible connecting sleeve is provided between the feed hopper and the U-shaped conveyor frame.

[0020] This invention also discloses a method of using a coal slime drying and mixing device for coal slime reprocessing, comprising the following steps:

[0021] S1: The coal slime filter cake after being filtered by the filter press is placed in a U-shaped conveyor frame, and hot air is conveyed into the conveying chamber through a heat pipe;

[0022] S2: Controls the operation of the dual-axis output motor inside the movable block. The dual-axis output motor drives the eccentric block to rotate through the rotating shaft. The eccentric block drives the movable block to move up and down and left and right.

[0023] When the movable block moves up and down, it drives the U-shaped conveyor frame to shake up and down through the connecting rod, which in turn throws the coal slime filter cake on the U-shaped conveyor frame up, so that the bottom of the coal slime filter cake can come into contact with hot air.

[0024] When the movable block moves left and right, it ensures that the coal slime filter cake on the U-shaped conveyor is always conveyed toward the end of the U-shaped conveyor.

[0025] S3: When the rotating shaft rotates, it drives the reciprocating screw to rotate through the first synchronous wheel and the first synchronous belt. The sleeve moves back and forth along the axis of the reciprocating screw. When the U-shaped conveyor moves up and throws the coal slime filter cake, the sleeve drives the shovel to move towards the middle of the U-shaped conveyor through the connecting rod, so that the shovels on both sides of the U-shaped conveyor come closer to each other and remove the coal slime filter cake that is stuck to the inner wall of the U-shaped conveyor. When the U-shaped conveyor moves down, the sleeve drives the shovel to move back and reset, so that the coal slime filter cake falls back onto the inner wall of the U-shaped conveyor.

[0026] S4: When the movable block moves up and down, it drives the lower toothed plate to move up and down reciprocally through the lower connecting plate. When the lower toothed plate moves up and down reciprocally, it meshes with the movable gear, causing the upper toothed plate to move up and down reciprocally. The upper toothed plate drives the connecting plate to move up and down reciprocally through the upper connecting plate, which in turn causes the U-shaped conveyor to move up and throw the coal slime filter cake. When the connecting plate drives the cutter to move down, it cuts the coal slime filter cake, causing it to break and increasing the contact area between the coal slime filter cake and the hot air. The coal slime filter cake is dried quickly. When the U-shaped conveyor moves down, the connecting plate drives the cutter to move up and enter the protective shell. The coal slime debris adhering to the outside of the cutter is scraped off by the protective shell. After the cutter enters the main shell from the movable shell, the movable shell deflects and resets relative to the main shell under the action of the torsion spring at the pin shaft. The swinging movable shell shakes off the coal slime debris left on the outside when cleaning the cutter.

[0027] S5: The dried coal slime is conveyed to the end of the U-shaped conveyor and piled up. The rotating rod rotates with the reciprocating screw under the action of the second synchronous wheel and the second synchronous belt. When the rotating rod rotates, it drives the material feeding plate to rotate, so that the material feeding plate orderly releases the coal slime piled at the end of the U-shaped conveyor. The coal slime falling from the U-shaped conveyor is initially mixed with the clean coal fed into the first pipe. The clean coal and coal slime automatically slide down the inclined surface of the inner wall of the first pipe into the second pipe.

[0028] S6: The second pipe body rotates in one direction under the action of the third synchronous pulley and the third synchronous belt as the rotating rod rotates in both directions. When the second pipe body rotates in one direction, the lifting plate turns and mixes the clean coal and the dried coal slime, and conveys the mixed coal to the discharge end of the second pipe body to realize the drying and mixing of the coal slime.

[0029] Compared with the prior art, the present invention provides a coal slime drying and mixing device and its usage method for coal slime reprocessing, which has the following beneficial effects:

[0030] 1. The coal slime drying and mixing device for coal slime reprocessing and its usage method, through the vibration component driving the U-shaped conveyor frame to shake up and down while conveying the coal slime filter cake, so that the coal slime filter cake is thrown up during the conveying process, avoiding the bottom of the coal slime filter cake from always being in contact with the conveying surface during the conveying process, so that the bottom of the coal slime filter cake can contact the hot air, reducing the occurrence of clumps during coal slime mixing, facilitating the full drying of coal slime, and improving the drying quality and drying efficiency of coal slime filter cake;

[0031] 2. The coal slime drying and mixing device for coal slime reprocessing and its usage method, wherein when the coal slime filter cake is thrown up by the U-shaped conveyor frame, the sleeve drives the shovel plate to move towards the middle of the U-shaped conveyor frame through the connecting rod, so that the shovel plates on both sides of the U-shaped conveyor frame come closer to each other, and remove the coal slime filter cake that is stuck to the inner wall of the U-shaped conveyor frame. When the U-shaped conveyor frame moves down, the sleeve drives the shovel plate to move back to its original position, so that the coal slime filter cake falls back onto the inner wall of the U-shaped conveyor frame, thus preventing the coal slime filter cake from sticking to the conveying surface of the U-shaped conveyor frame due to moisture, thereby effectively preventing coal slime blockage or accumulation, ensuring the smoothness of coal slime feeding, and thus improving the coal slime processing output and processing quality;

[0032] 3. The coal slime drying and mixing device for coal slime reprocessing and its usage method: when the coal slime filter cake is thrown up by the U-shaped conveyor frame, the connecting plate drives the cutter to move down to cut the coal slime filter cake, causing the coal slime filter cake to break, increasing the contact area between the coal slime filter cake and the hot air, accelerating the evaporation of moisture in the coal slime, and improving the coal slime drying efficiency.

[0033] 4. The coal slime drying and mixing device for coal slime reprocessing and its usage method: The connecting plate drives the cutter to move upward and enter the protective shell. The coal slime debris adhering to the outside of the cutter is scraped off by the protective shell. After the cutter enters the main shell from the movable shell, the movable shell deflects and resets relative to the main shell under the action of the torsion spring at the pin shaft. The swinging movable shell shakes off the coal slime debris remaining on the outside due to cleaning the cutter, avoiding excessive coal slime adhering to the protective shell and causing coal slime waste, thus ensuring the coal slime mixing output.

[0034] 5. The coal slime drying and mixing device for coal slime reprocessing and its usage method, by accumulating the dried coal slime at the end of the U-shaped conveyor frame, and then using the feeding plate to orderly release the coal slime accumulated at the end of the U-shaped conveyor frame, ensuring uniform and continuous feeding of the coal slime, the fed coal slime comes into contact with clean coal in the mixing pipe, and the feeding plate turns and mixes the clean coal and the dried coal slime, ensuring the homogenization of coal slime mixing production.

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0048] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0049] Example 1: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 A coal slime drying and mixing device for coal slime reprocessing, comprising a shell 1, and further comprising:

[0050] The feeding mechanism includes a vibration assembly disposed on the bottom side inside the housing 1 and a U-shaped conveyor frame 2 disposed on the top side of the vibration assembly;

[0051] Top plate 3 is set on the upper side of U-shaped conveyor frame 2. Top plate 3 and U-shaped conveyor frame 2 together form a conveying cavity for conveying coal slime filter cake. A fixing rod 101 is set between top plate 3 and inner wall of outer shell 1. A rupture component is set on top plate 3.

[0052] Heat pipe 4 is connected to top plate 3. An inclined air groove 401 facing the feeding direction of the feeding mechanism is opened in the top plate 3. Heat pipe 4 and inclined air groove 401 are interconnected.

[0053] And mixing pipe 5, which is set at the end of housing 1 via support plate 102, for receiving materials conveyed by U-shaped conveyor frame 2;

[0054] A transmission component is provided between the vibration component and the rupture component.

[0055] Specifically, the coal slime filter cake after being pressed by the filter press is placed in the U-shaped conveyor frame 2, and hot air is conveyed into the conveying chamber through the heat conduction pipe 4. The inclined air groove 401 allows the hot air to be discharged from the feed end to the discharge end of the conveying chamber, thereby heating and drying the coal slime filter cake during conveying. Then, the vibration component is controlled to operate, causing the vibration component to drive the U-shaped conveyor frame 2 to move back and forth and shake up and down, causing the coal slime filter cake to be thrown up during conveying. This prevents the bottom of the coal slime filter cake from always being in contact with the conveying surface during the conveying process, allowing the bottom of the coal slime filter cake to contact the hot air, reducing the occurrence of clumps during coal slime mixing, facilitating the full drying of the coal slime, improving the drying quality and efficiency of the coal slime filter cake, and the dried coal slime enters the mixing pipe 5 and is uniformly mixed with the clean coal in the mixing pipe 5, ensuring the homogenization of the coal slime mixing production.

[0056] Example 2: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 The coal slime drying and mixing device for coal slime reprocessing, based on Embodiment 1, further includes a vibration component comprising a base 7 fixed inside the outer casing 1, a U-shaped frame 701 fixed on the top of the base 7, first slide rods 702 slidably connected to both sides of the U-shaped frame 701, a movable frame 703 between the two first slide rods 702, a first elastic element 704 between the movable frame 703 and the U-shaped frame 701, second slide rods 705 on both sides of the movable frame 703, a movable block 706 slidably connected to the second slide rods 705, a second elastic element 707 between the movable block 706 and the movable frame 703, a dual-shaft output motor fixed in the middle of the movable block 706, two output shafts of the dual-shaft output motor connected to a rotating shaft 708 rotatably connected to the movable block 706, an eccentric block 709 on the rotating shaft 708, and a connecting rod 7061 between the movable block 706 and the U-shaped conveyor frame 2.

[0057] Specifically, when the vibration assembly is running, the dual-axis output motor inside the control movable block 706 operates (the dual-axis output motor is existing technology and will not be described in detail here; it is not shown in the figure). The dual-axis output motor drives the eccentric block 709 to rotate via the rotating shaft 708. The eccentric block 709 drives the movable block 706 to move up and down relative to the movable frame 703 and to move left and right relative to the U-shaped frame 701. When the movable block 706 moves up and down, it drives the U-shaped conveyor frame 2 to vibrate up and down via the connecting rod 7061, thereby causing the coal slime filter cake on the U-shaped conveyor frame 2 to be thrown up, so that the bottom of the coal slime filter cake can come into contact with hot air, which is convenient for the coal slime to be fully dried. When the movable block 706 moves left and right, it can ensure that the coal slime filter cake on the U-shaped conveyor frame 2 is always conveyed towards the end of the U-shaped conveyor frame 2. The first elastic element 704 and the second elastic element 707 are both springs.

[0058] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10The coal slime drying and mixing device for coal slime reprocessing, based on embodiment 2, further includes support plates 8 fixed on both sides of the bottom of the U-shaped conveyor frame 2. A reciprocating screw 801 is rotatably connected inside the support plate 8. A sleeve 802 is threadedly connected to the reciprocating screw 801. The sleeve 802 is connected to a shovel plate 803 that moves against the inner wall of the U-shaped conveyor frame 2 via a connecting rod. The shovel plate 803 is slidably connected to the U-shaped conveyor frame 2. A first synchronous wheel 9 is provided on both the reciprocating screw 801 and the rotating shaft 708. A first synchronous belt is provided between the two first synchronous wheels 9.

[0059] Specifically, when the rotating shaft 708 rotates, it drives the reciprocating screw 801 to rotate via the first synchronous wheel 9 and the first synchronous belt. The sleeve 802 moves back and forth along the axial direction of the reciprocating screw 801. When the U-shaped conveyor frame 2 moves upward and throws the coal slime filter cake, the sleeve 802 drives the shovel plate 803 to move towards the middle of the U-shaped conveyor frame 2 via the connecting rod, so that the shovel plates 803 on both sides of the U-shaped conveyor frame 2 move closer to each other and remove the coal slime filter cake that is stuck to the inner wall of the U-shaped conveyor frame 2. When the U-shaped conveyor frame 2 moves downward, the sleeve 802 drives the shovel plate 803 to move back and reset, so that the coal slime filter cake falls back onto the inner wall of the U-shaped conveyor frame 2. This prevents the coal slime filter cake from sticking to the conveying surface of the U-shaped conveyor frame 2 due to moisture, thereby effectively preventing coal slime from clogging or accumulating, ensuring the smoothness of coal slime feeding, avoiding feeding interruption that leads to uneven mixing, and thus improving the output and quality of coal slime mixing processing.

[0060] Example 4: Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The coal slime drying and mixing device for coal slime reprocessing, based on Example 3, further includes a rupture component comprising a plurality of cutters 10 slidably connected to the top plate 3, a connecting plate 1001 disposed on the top of the cutters 10, and an elastic telescopic rod 1002 disposed between the connecting plate 1001 and the inner wall of the outer shell 1.

[0061] Furthermore, the transmission assembly includes a rotating rod 11 rotatably connected to the housing 1, a movable gear 111 is provided on the rotating rod 11, an upper gear plate 112 and a lower gear plate 113 are respectively meshed on both sides of the movable gear 111, an upper connecting plate 1121 is provided between the upper gear plate 112 and the connecting plate 1001, a lower connecting plate 1131 is provided on the lower gear plate 113, and a sliding groove 7062 for sliding the lower connecting plate 1131 is provided on the movable block 706.

[0062] Specifically, when the movable block 706 moves up and down, it drives the lower toothed plate 113 to move up and down reciprocally via the lower connecting plate 1131. When the lower toothed plate 113 moves up and down reciprocally, it meshes with the movable gear 111, causing the upper toothed plate 112 to move up and down reciprocally. The upper toothed plate 112 drives the connecting plate 1001 to move up and down reciprocally via the upper connecting plate 1121. This causes the U-shaped conveyor frame 2 to move up and throw the coal slime filter cake. When the connecting plate 1001 moves down, it drives the cutter 10 to move down and cut the coal slime filter cake, causing the coal slime filter cake to break and increasing the contact area between the coal slime filter cake and the hot air. The coal slime filter cake is dried quickly. When the U-shaped conveyor frame 2 moves down, the cutter 10 moves up and resets with the connecting plate 1001.

[0063] Example 5: Refer to Figure 4 , Figure 5 , Figure 6 , Figure 9 and Figure 10 The coal slime drying and mixing device for coal slime reprocessing, based on Example 4, further includes a protective shell 12 fixedly provided at the bottom of the top plate 3, corresponding to a plurality of cutters 10. The cutters 10 are slidably connected inside the protective shell 12. The protective shell 12 includes a main shell 121 fixedly connected to the top plate 3 and a movable shell 122 rotatably connected to the bottom of the main shell 121 via a pin. A torsion spring for driving the movable shell 122 to reset and rotate is sleeved on the pin.

[0064] Specifically, when the movable block 706 moves up and down, it drives the lower toothed plate 113 to move up and down reciprocally via the lower connecting plate 1131. When the lower toothed plate 113 moves down, the connecting plate 1001 drives the cutter 10 to move up and enter the protective shell 12. The coal slurry debris adhering to the outside of the cutter 10 is scraped off by the protective shell 12. After the cutter 10 enters the main shell 121 from the movable shell 122, the movable shell 122 deflects and resets relative to the main shell 121 under the action of the torsion spring at the pin. The swinging movable shell 122 shakes off the coal slurry debris remaining on the outside when cleaning the cutter 10, avoiding excessive coal slurry adhering to the protective shell 12 and causing coal slurry waste, thus ensuring the coal slurry mixing output.

[0065] Example 6: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 The coal slime drying and mixing device for coal slime reprocessing, based on Example 5, further includes an outlet 14 at the end of the U-shaped conveyor frame 2, a rotating rod 141 at the outlet 14, a circumferentially distributed feeding plate 142 on the rotating rod 141, a second synchronous wheel 15 on both the rotating rod 141 and the reciprocating screw 801, and a second synchronous belt between the two second synchronous wheels 15.

[0066] Specifically, the dried coal slime is conveyed to the end of the U-shaped conveyor frame 2 and piled up. The rotating rod 141 rotates with the reciprocating screw 801 under the action of the second synchronous wheel 15 and the second synchronous belt. When the rotating rod 141 rotates, it drives the material feeding plate 142 to rotate, so that the material feeding plate 142 orderly releases the coal slime piled at the end of the U-shaped conveyor frame 2, ensuring that the coal slime is fed evenly and continuously, thereby ensuring the homogenization of coal slime mixing production.

[0067] Example 7: Refer to Figure 1 , Figure 2 and Figure 11 The coal slime drying and mixing device for coal slime reprocessing, based on embodiment 6, further includes a mixing pipe 5 comprising a first pipe body 501 fixedly connected to the support plate 102 and a second pipe body 502 rotatably connected to the first pipe body 501. The top of the first pipe body 501 is provided with a feed inlet, and a feed hopper 5011 is provided at the feed inlet of the first pipe body 501. Several lifting plates 5021 are provided on the inner wall of the second pipe body 502. The lifting plates 5021 are configured as bent plates. A third synchronous wheel 16 is provided on both the second pipe body 502 and the rotating rod 11. A third synchronous belt is provided between the two third synchronous wheels 16. The third synchronous wheel 16 on the outer side of the second pipe body 502 adopts a flywheel structure.

[0068] Specifically, the coal slurry falling from the U-shaped conveyor 2 is initially mixed with the clean coal fed into the first pipe 501. The clean coal and coal slurry automatically slide down the inclined inner wall of the first pipe 501 into the second pipe 502. Under the action of the third synchronous wheel 16 and the third synchronous belt, the second pipe 502 rotates in one direction as the rotating rod 11 rotates in both directions. When the second pipe 502 rotates in one direction, the lifting plate 5021 turns and mixes the clean coal and the dried coal slurry, and conveys the mixed coal to the discharge end of the second pipe 502, thus realizing the drying and mixing of the coal slurry. It should be noted that the flywheel structure adopted by the third synchronous wheel 16 on the outside of the second pipe 502 is existing technology.

[0069] Example 8: Refer to Figure 1 and Figure 3 The coal slime drying and mixing device for coal slime reprocessing, based on Example 7, further includes a flexible sealing element 13 between the top plate 3 and the U-shaped conveyor frame 2, and a flexible connecting sleeve 6 between the feed hopper 5011 and the U-shaped conveyor frame 2.

[0070] Specifically, the flexible sealing element 13 and the flexible connecting sleeve 6 make it difficult for hot air in the conveying chamber to escape, ensuring the drying effect of coal slime in the conveying chamber, while preventing coal ash from flying away during coal slime drying.

[0071] This invention also discloses a method of using a coal slime drying and mixing device for coal slime reprocessing, comprising the following steps:

[0072] S1: The coal slime filter cake after being filtered by the filter press is placed in the U-shaped conveyor frame 2, and hot air is conveyed into the conveying chamber through the heat pipe 4;

[0073] S2: Control the operation of the dual-axis output motor in the movable block 706. The dual-axis output motor drives the eccentric block 709 to rotate through the rotating shaft 708. The eccentric block 709 drives the movable block 706 to move up and down and left and right.

[0074] When the movable block 706 moves up and down, it drives the U-shaped conveyor frame 2 to shake up and down through the connecting rod 7061, thereby causing the coal slime filter cake on the U-shaped conveyor frame 2 to be thrown up, so that the bottom of the coal slime filter cake can come into contact with hot air.

[0075] When the movable block 706 moves left and right, it can ensure that the coal slime filter cake on the U-shaped conveyor frame 2 is always conveyed towards the end of the U-shaped conveyor frame 2;

[0076] S3: When the rotating shaft 708 rotates, it drives the reciprocating screw 801 to rotate through the first synchronous wheel 9 and the first synchronous belt. The sleeve 802 moves back and forth along the axial direction of the reciprocating screw 801. When the U-shaped conveyor 2 moves up and throws the coal slime filter cake, the sleeve 802 drives the shovel plate 803 to move towards the middle of the U-shaped conveyor 2 through the connecting rod, so that the shovel plates 803 on both sides of the U-shaped conveyor 2 move closer to each other and remove the coal slime filter cake that is stuck to the inner wall of the U-shaped conveyor 2. When the U-shaped conveyor 2 moves down, the sleeve 802 drives the shovel plate 803 to move back and reset, so that the coal slime filter cake falls back onto the inner wall of the U-shaped conveyor 2.

[0077] S4: When the movable block 706 moves up and down, it drives the lower toothed plate 113 to move up and down reciprocally via the lower connecting plate 1131. The lower toothed plate 113 meshes with the movable gear 111 during this reciprocating motion, causing the upper toothed plate 112 to move up and down reciprocally. The upper toothed plate 112, through the upper connecting plate 1121, drives the connecting plate 1001 to move up and down reciprocally. This causes the U-shaped conveyor frame 2 to move upwards and throw the coal slime filter cake. Simultaneously, the connecting plate 1001 drives the cutter 10 to move downwards to cut the coal slime filter cake, causing it to break. The contact area between the coal slime filter cake and the hot air is increased, and the coal slime filter cake is dried quickly. When the U-shaped conveyor frame 2 moves down, the connecting plate 1001 drives the cutter 10 to move up and enter the protective shell 12. The coal slime debris adhering to the outside of the cutter 10 is scraped off by the protective shell 12. After the cutter 10 enters the main shell 121 from the movable shell 122, the movable shell 122 deflects and resets relative to the main shell 121 under the action of the torsion spring at the pin. The swinging movable shell 122 shakes off the coal slime debris left on the outside when cleaning the cutter 10.

[0078] S5: The dried coal slime is conveyed to the end of the U-shaped conveyor 2 and piled up. The rotating rod 141 rotates with the reciprocating screw 801 under the action of the second synchronous wheel 15 and the second synchronous belt. When the rotating rod 141 rotates, it drives the material feeding plate 142 to rotate, so that the material feeding plate 142 orderly drops the coal slime piled at the end of the U-shaped conveyor 2. The coal slime falling from the U-shaped conveyor 2 is initially mixed with the clean coal fed into the first pipe 501. The clean coal and coal slime automatically slide down the inclined surface of the inner wall of the first pipe 501 into the second pipe 502.

[0079] S6: The second pipe body 502 rotates in one direction under the action of the third synchronous wheel 16 and the third synchronous belt as the rotating rod 11 rotates in both directions. When the second pipe body 502 rotates in one direction, the lifting plate 5021 turns and mixes the clean coal and the dried coal slime, and conveys the mixed coal to the discharge end of the second pipe body 502 to realize the drying and mixing of the coal slime.

[0080] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
