Description

Technical Field

[0001] This invention relates to the field of coal mine transportation technology, and in particular to a coal-water separation device for belt conveyors. Background Technology

[0002] Existing coal mining methods include mechanical mining, hydraulic mining, and blasting mining. When mechanical mining is not feasible in some steeply inclined or unstable coal seams, blasting and hydraulic mining are often employed. Hydraulic mining is a mechanized coal mining technology that uses high-pressure water jets to break up the coal mass and leverages water power to complete its transportation and hoisting processes.

[0003] After the hydraulic mining method is completed, the coal needs to be transported out of the mine. This requires multi-stage conveyor belts. However, the coal extracted by hydraulic mining contains a large amount of water, so the coal transported out of the mine needs to undergo coal-water separation. This adds an extra step to the hydraulic mining method, which in turn affects efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a belt conveyor coal-water separation device, which solves the technical problem that after the coal is collected outside the coal mine by hydraulic coal mining, it still needs to go through a coal-water separation step, which affects the efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] This invention provides a coal-water separation device for a belt conveyor, comprising a coal-water separation support mounted on one side of two horizontally and vertically arranged conveyor belts, a coal separation screen mounted on the coal-water separation support perpendicular to the upper conveyor belt and receiving the coal flow falling from the upper conveyor belt, and a water receiving hopper mounted on the coal-water separation support and located below the coal separation screen. The coal separation screen is inclined downward along the conveying direction of the lower conveyor belt, and a coal sliding groove is formed in the middle of the coal separation screen for coal to fall and slide onto the lower conveyor belt. The coal separation screen has evenly arranged drainage holes for water to fall. The water receiving hopper is inclined along the extension direction of the upper conveyor belt and receives the water flow leaking from the coal separation screen and discharges it to the side of the lower conveyor belt.

[0009] This invention discloses a coal-water separation device for a belt conveyor. When using this device to separate coal and water, the coal-water separation support is set up on one side of the upper and lower conveyor belts, so that the coal separation screen is located between the upper and lower conveyor belts. The coal falling from the upper conveyor belt falls into the coal sliding chute of the coal separation screen. At this time, the coal will not stop, but will slide down along the coal falling chute until it falls onto the next level conveyor belt. During the process of the coal sliding down, the water contained in it will leak down through the drainage hole into the water receiving hopper. Finally, the water receiving hopper discharges the water to one side of the conveyor belt. This solution separates coal and water during the process of coal being transported out of the coal mine, thereby eliminating the step of coal-water separation outside the coal mine and improving coal mining efficiency. At the same time, the coal-water separation effect can be improved by setting this device between two adjacent conveyor belts.

[0010] Optionally, the coal-water separation support includes a vertically arranged support base, a transposition shaft coaxially rotatably arranged on the top of the support base, and a connecting frame evenly spaced around the periphery of the transposition shaft. The coal separation screen is provided with multiple screens, each of which is fixedly connected to one end of the connecting frame away from the transposition shaft.

[0011] The base supports the bottom, allowing the shifting shaft to rotate coaxially on top of the base, which in turn drives the surrounding connecting frame to rotate synchronously. Multiple coal separation screens are set up and connected to the connecting frame respectively, so that the coal separation screens can be shifted through the shifting shaft. After a period of coal-water separation, some of the water leakage holes on the coal separation screen will become blocked, thus affecting the efficiency of coal-water separation. This solution replaces the coal separation screen to maintain the efficiency of coal-water separation.

[0012] Optionally, the connecting frame includes two horizontal rods that are horizontally spaced and perpendicular to the rotation axis of the shifting shaft and connected to the side end of the shifting shaft, a connecting crossbar connected to the end of the two horizontal rods away from the shifting shaft, and an inclined support rod that is inclinedly arranged at the side end of the shifting shaft and whose end is connected to the connection between the horizontal rods and the connecting crossbar. The coal separating screen is fixed to the side end of the connecting crossbar away from the shifting shaft.

[0013] By setting two horizontal bars, one connecting crossbar, and two inclined support bars on the connecting frame, the entire connecting frame forms a three-dimensional triangle, fixing the coal separation screen to the connecting crossbar. This allows the connecting frame to provide a more stable support effect for the coal separation screen when the coal flows onto it.

[0014] Optionally, a connecting plate is vertically arranged on the connecting crossbar, and a connecting shaft is vertically arranged at the end of the connecting plate away from the shifting shaft. The end of the coal separating screen away from the conveying direction of the lower conveyor belt is rotatably connected to the connecting shaft. An adjusting rod parallel to the connecting shaft is arranged at the lower end of the coal separating screen away from the connecting shaft. An arc-shaped adjusting slide hole is opened on the connecting plate with the connecting shaft as the axis. One end of the adjusting rod is inserted into the adjusting slide hole and slides and is fixed along the length direction of the adjusting slide hole.

[0015] By setting a connecting plate on the connecting crossbar, the coal separation screen is rotatably connected to the connecting plate via the connecting shaft. Then, the adjusting rod is inserted into the adjusting slide hole and slides along the adjusting slide hole before being fixed. This allows the tilt angle of the coal separation screen to be adjusted and fixed according to actual needs, thereby achieving faster coal flow and better coal-water separation effect, which is more convenient.

[0016] Optionally, the lower end of the coal separating screen is provided with four sets of rotating seats near the corners. The connecting shaft is rotatably inserted through two sets of rotating seats and fixed to the connecting plate. The adjusting rod is rotatably inserted through the other two sets of rotating seats and inserted into the adjusting sliding hole. Two positioning nuts are threadedly connected to the adjusting rod. The two positioning nuts are located on both sides of the connecting plate and clamp the connecting plate.

[0017] By passing the connecting shaft through two sets of rotating seats and fixing them to the connecting plate, the entire coal separation screen is rotatably connected to the connecting plate. Then, the adjusting rod is rotatably passed through two other sets of rotating seats, and two positioning nuts are threaded onto the adjusting rod. The two positioning nuts can fix the coal separation screen by clamping the connecting plate. On the one hand, the tilt angle of the coal separation screen can be adjusted according to actual needs. On the other hand, by unscrewing the positioning nut on one side of the positioning plate, the adjusting rod can be disassembled, so that the coal separation screen can be flipped over to clean the coal blocks embedded in the drainage holes.

[0018] Optionally, the support base includes a base body supported on the ground and extending horizontally toward the side of the coal separation screen that receives the coal flow, and a support column vertically slidably disposed on the upper end of the base body. A support rod is vertically disposed on the upper end of the base body, and multiple support adjustment rings are coaxially sleeved on the support rod. A support insertion hole is coaxially opened at the lower end of the support column for the support rod to be vertically inserted.

[0019] By setting the support base with a base body and a support column, the base body extends horizontally towards the coal separation screen that receives the coal flow. This ensures that the center of gravity of the entire belt conveyor coal-water separation device is located in the middle when the coal separation screen is bearing the coal flow, making it more stable. At the same time, multiple support adjustment rings are coaxially sleeved on the support rod, so that the number of support adjustment rings can be adjusted as needed, thereby controlling the height of the support column, and thus the height of the coal separation screen can be adjusted as needed, which is more convenient.

[0020] Optionally, multiple water receiving hoppers are provided and are respectively located on the lower side of the coal separating screen. A water trough is formed in the middle of the water receiving hopper, and a water receiving box is provided on the upper end of the base body on the lower side of the water receiving hopper to receive the water flowing down.

[0021] By setting multiple water receiving hoppers and matching them one by one with the coal separation screen, the separated water flow will accurately fall into the water trough every time the coal separation screen is rotated and replaced. Furthermore, by setting a water receiving tank at the top of the base body, the water flowing down the water trough will fall directly into the water receiving tank. On the one hand, the water flow from the coal-water separation is collected for reuse, reducing water waste. On the other hand, as the coal-water separation proceeds, the weight of the entire base body gradually increases, making the entire belt conveyor coal-water separation device more stable during operation.

[0022] Optionally, the upper side of the coal separating screen is provided with a fan that blows air into the coal flow in the coal sliding trough.

[0023] By tilting the fan on the upper side of the coal separation screen, the fan blows air into the coal sliding trough, thereby accelerating the coal-water separation effect.

[0024] Optionally, the coal sliding chute is configured to gradually narrow along the direction of coal sliding.

[0025] By setting the coal chute on the coal separating screen to be wider at the higher end and narrower at the lower end, the coal separating screen can better catch the coal falling from the conveyor belt, and the narrowing allows the coal to fall more concentratedly onto the lower conveyor belt, thereby enhancing the transportation of coal.

[0026] Optionally, the coal-water separation support includes a vertically arranged vertical frame, a horizontal frame rotatably connected to the top of the vertical frame with a horizontally rotating shaft, two bridge frames horizontally arranged at the top of the vertical frame and extending towards and away from the upper conveyor belt respectively, and a striking frame horizontally and vertically connected to the end of the bridge frames. The coal separation screen is connected to the end of the horizontal frame away from the vertical frame. When the horizontal frame abuts against the striking frame on the side near the conveyor belt, the coal separation screen performs coal-water separation. When the horizontal frame rotates to the other side, it collides with the striking frame and shakes off the coal blocks embedded in the coal separation screen.

[0027] By configuring the coal-water separation support as a vertical frame, horizontal frame, bridge frame, and striking frame, during normal use, the horizontal frame abuts against the striking frame on the side closest to the conveyor belt, allowing the coal separation screen to perform coal-water separation normally. After a period of use, some of the drainage holes on the coal separation screen will become clogged. At this time, rotating the horizontal frame causes it to collide with the striking frame on the other side, thereby shaking off the coal blocks blocking the drainage holes. Then, the screen is reset. This design makes cleaning the clogged coal blocks on the coal separation screen easier and more convenient.

[0028] (III) Beneficial Effects

[0029] The beneficial effects of this invention are as follows: When the belt conveyor coal-water separation device of this invention is used to separate coal and water, the coal-water separation support is set on one side of the upper and lower conveyor belts, so that the coal separation screen is located between the upper and lower conveyor belts. The coal falling from the upper conveyor belt falls into the coal sliding trough of the coal separation screen. At this time, the coal will not stop, but will slide down along the coal falling trough until it falls onto the next level conveyor belt. During the process of the coal sliding down, the water contained in it will leak down through the water leakage hole into the water receiving hopper. Finally, the water receiving hopper discharges the water to one side of the conveyor belt. This solution performs coal-water separation during the process of coal being transported out of the coal mine, thereby omitting the coal-water separation step outside the coal mine and improving coal mining efficiency. At the same time, the coal-water separation effect can be improved by setting this device between two adjacent conveyor belts. Attached Figure Description

[0035] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The coal-water separation device for belt conveyors proposed in this invention, when used to separate coal and water, involves setting up a coal-water separation support on one side of the upper and lower conveyor belts, so that the coal separation screen is located between the upper and lower conveyor belts. This allows the coal falling from the upper conveyor belt to fall directly into the coal sliding trough of the coal separation screen. The coal will not stop but will slide down the coal sliding trough until it falls onto the next level conveyor belt. During this sliding process, the water contained in the coal will leak through the drainage holes into the water receiving hopper. Finally, the water receiving hopper discharges the water to one side of the conveyor belt. This solution separates coal and water during the process of transporting coal out of the coal mine, thus eliminating the need for external coal-water separation and improving coal mining efficiency. Furthermore, the coal-water separation effect can be further improved by installing this device between adjacent conveyor belts.

[0037] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0038] Example 1

[0039] Reference Figure 1 and Figure 2A coal-water separation device for a belt conveyor includes a coal-water separation support 1 installed on one side of two sets of horizontally and vertically arranged conveyor belts, a coal separation screen 2 installed on the coal-water separation support 1 perpendicular to the upper conveyor belt and receiving the coal flow falling from the upper conveyor belt, and a water receiving hopper 3 installed on the coal-water separation support 1 and located below the coal separation screen 2.

[0040] The coal separating screen 2 extends downward along the lower conveyor belt and is inclined downward. A coal sliding trough 21 is formed in the middle of the coal separating screen 2, which allows coal to fall and slide onto the lower conveyor belt. Water leakage holes 22 are evenly arrayed on the coal separating screen 2. The water receiving hopper 3 is inclined along the upper conveyor belt and receives the water leakage from the coal separating screen 2 and discharges it to the side of the lower conveyor belt. When using this belt conveyor coal-water separation device to separate coal and water, the coal-water separation bracket 1 is set up on one side of the upper and lower conveyor belts, so that the coal separation screen 2 is located between the upper and lower conveyor belts. The coal falling from the upper conveyor belt falls into the coal sliding chute 21 of the coal separation screen 2. At this time, the coal will not stop, but will slide down along the coal falling chute until it falls onto the next level conveyor belt. During the process of the coal sliding down, the water contained in it will leak down through the water leakage hole 22 into the water receiving hopper 3. Finally, the water receiving hopper 3 discharges the water to one side of the conveyor belt.

[0041] The coal chute 21 is designed to gradually narrow along the direction of coal descent. This allows the coal separating screen 2 to better catch the coal falling from the conveyor belt, and the narrowing design also allows the coal to fall more concentratedly onto the lower conveyor belt.

[0042] The coal-water separation support 1 includes a vertically arranged support base 11, a shifting shaft 12 coaxially connected to the top of the support base 11 and driven by a motor, and connecting frames 13 evenly spaced around the periphery of the shifting shaft 12. Multiple coal separation screens 2 are provided, each fixedly connected to one end of the connecting frame 13 away from the shifting shaft 12. The shifting shaft 12 can be used to shift the position of the coal separation screens 2, allowing them to be replaced after a period of coal-water separation operation to maintain efficiency and reduce the impact of blocked drainage holes 22 on the coal separation screens 2.

[0043] The connecting frame 13 includes two horizontal rods 131, horizontally spaced and perpendicular to the rotation axis of the transposition shaft 12 and welded to the side of the transposition shaft 12; a connecting crossbar 132 welded to the end of the two horizontal rods 131 away from the transposition shaft 12; and an inclined support rod 133 welded to the side of the transposition shaft 12 and connected at its end to the junction of the horizontal rods 131 and the connecting crossbar 132. The coal separating screen 2 is fixed to the side of the connecting crossbar 132 away from the transposition shaft 12. The two horizontal rods 131, the connecting crossbar 132, and the two inclined support rods 133 form a three-dimensional triangle, fixing the coal separating screen 2 to the connecting crossbar 132. This allows the connecting frame 13 to provide a more stable support effect for the coal separating screen 2 when coal flows onto it.

[0044] A connecting plate 14 is vertically fixed to the connecting crossbar 132 by bolts. A connecting shaft 141 is vertically welded to the end of the connecting plate 14 away from the shifting shaft 12. The end of the coal separating screen 2 away from the conveying direction of the lower conveyor belt is rotatably connected to the connecting shaft 141. An adjusting rod 142 parallel to the connecting shaft 141 is provided at the lower end of the coal separating screen 2 away from the connecting shaft 141. An arc-shaped adjusting sliding hole 143 is formed on the connecting plate 14 with the connecting shaft 141 as its axis. The adjusting rod 14... One end of the 2 is inserted into the adjusting slide hole 143 and slides and is fixed along the length of the adjusting slide hole 143. Four sets of rotating seats 23 are welded to the lower end of the coal separating screen 2 near the corner. The connecting shaft 141 is rotatably inserted through two sets of rotating seats 23 and fixed to the connecting plate 14. The adjusting rod 142 is rotatably inserted through the other two sets of rotating seats 23 and inserted into the adjusting slide hole 143. Two positioning nuts 144 are threaded on the adjusting rod 142. The two positioning nuts 144 are located on both sides of the connecting plate 14 and clamp the connecting plate 14. The connecting shaft 141 is threaded through two sets of rotating seats 23 and fixedly connected to the connecting plate 14, so that the entire coal separation screen 2 is rotatably connected to the connecting plate 14. Then, the adjusting rod 142 is rotatably threaded through two other sets of rotating seats 23, and two positioning nuts 144 are threadedly connected to the adjusting rod 142, so that the two positioning nuts 144 can fix the coal separation screen 2 by clamping the connecting plate 14. On the one hand, the tilt angle of the coal separation screen 2 can be adjusted according to actual needs. On the other hand, the adjusting rod 142 can be disassembled by unscrewing the positioning nut 144 on one side of the positioning plate, so that the coal separation screen 2 can be flipped over to clean the coal lumps embedded in the water leakage hole 22.

[0045] The support base 11 includes a base body 111 supported on the ground and extending horizontally towards the coal separation screen 2 that receives the coal flow, and a support column 112 vertically slidably disposed on the upper end of the base body 111. A support rod 113 is vertically welded to the upper end of the base body 111, and multiple support adjustment rings 114 are coaxially sleeved on the support rod 113. A support insertion hole 1121 is coaxially opened at the lower end of the support column 112 for the support rod 113 to be vertically inserted. The base body 111 extends horizontally towards the coal separation screen 2 that receives the coal flow, thereby ensuring that the center of gravity of the entire belt conveyor coal-water separation device is located in the middle when the coal separation screen 2 receives the coal flow, making it more stable. At the same time, multiple support adjustment rings 114 are coaxially sleeved on the support rod 113, so that the number of support adjustment rings 114 can be adjusted as needed, thereby controlling the height of the support column 112, and thus the height of the coal separation screen 2, which is more convenient.

[0046] The top of the support column 112 is coaxially integrally formed with a main shaft 1122 that is rotatably inserted into the middle of the shift shaft 12. The top of the main shaft 1122 is fixed with a fan 4 located on the upper side of the coal separation screen 2 on the working side by bolts. The fan 4 is tilted and aimed at the coal flow in the coal sliding trough 21 to blow air, thereby accelerating the coal-water separation effect.

[0047] Multiple water receiving hoppers 3 are welded to the connecting plate 14 and located below the coal separating screen 2. A water trough 31 is formed in the middle of the water receiving hopper 3, allowing water to flow down in an inclined direction. A water receiving tank 5 is provided at the upper end of the base body 111 below the water receiving hopper 3 to collect the falling water. Each time the coal separating screen 2 is rotated and replaced, the separated water will fall accurately into the water trough 31. By setting the water receiving tank 5 at the upper end of the base body 111, the water flowing down through the water trough 31 will fall directly into the water receiving tank. On the one hand, the water from the coal-water separation is collected for reuse, reducing water waste. On the other hand, as the coal-water separation proceeds, the weight of the entire base body 111 gradually increases, making the entire belt conveyor coal-water separation device more stable during operation.

[0048] Example 2

[0049] The difference between this embodiment and Embodiment 1 is as follows:

[0050] See Figure 3The coal-water separation support 1 includes a vertically arranged vertical frame 15, a horizontal frame 16 rotatably connected to the top of the vertical frame 15 with a horizontally rotating shaft, two bridge frames 17 horizontally welded to the top of the vertical frame 15 and arranged in the direction of extending towards and away from the upper conveyor belt, and a striking frame 18 horizontally and vertically welded to the end of the bridge frame 17. The coal separation screen 2 is connected to the end of the horizontal frame 16 away from the vertical frame 15. When the horizontal frame 16 abuts against the striking frame 18 on the side close to the conveyor belt, the coal separation screen 2 performs coal-water separation. When the horizontal frame 16 rotates to the other side, it collides with the striking frame 18 and shakes off the coal blocks embedded in the coal separation screen 2. During normal use, the cross frame 16 abuts against the striking frame 18 on the side near the conveyor belt. At this time, the coal separation screen 2 can perform coal-water separation normally. After a period of use, some of the water leakage holes 22 on the coal separation screen 2 will be blocked. At this time, rotate the cross frame 16 so that the cross frame 16 collides with the striking frame 18 on the other side, thereby shaking off the coal blockage in the water leakage hole 22. Then, reset it. This solution makes it easier and more convenient to clean the coal blockage on the coal separation screen 2.
