Description

Technical Field

[0001] This utility model relates to the field of coal mine conveying equipment technology, and in particular to a conveyor with a coal-water dewatering device. Background Technology

[0002] In coal mining operations, underground belt conveyors efficiently and continuously transport coal. The conveyor belt is made of a flexible, flame-retardant material and, supported by idlers, forms an arc shape to effectively support the coal. Coal mining generates a large amount of dust, necessitating dust suppression spraying. Additionally, the spraying of supports, internal and external spraying of the coal mining machine, motor cooling water, and the structure of the belt's bearing surface all contribute to increased water accumulation on the belt. This water accumulation leads to excessively high moisture content in the coal transported by the belt conveyor, resulting in water-coal mixture. This water-coal mixture easily slips on the belt, and when the gradient of the transported coal is steep, it can backflow and clog the belt, affecting normal coal transport and even causing serious accidents such as belt shutdowns, requiring significant manpower for handling.

[0003] In conclusion, developing a conveyor capable of dehydrating coal and water is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a conveyor with a water-coal dewatering device, which solves the technical problem of water mist used for dust suppression accumulating on the conveyor, generating water-coal, and affecting coal mine transportation.

[0005] To achieve the above objectives, this utility model provides a conveyor with a coal-water dewatering device, comprising:

[0006] The support frame has adjustable idlers on both sides, with a conveyor belt between each idler. Each idler is connected to a drive cylinder at the end away from the conveyor belt. The drive cylinder drives the idler to rotate around the length of the support frame. When the drive cylinder extends, the idlers on both sides of the support frame tilt towards each other, so that the conveyor belt is concave. The conveyor belt is used to support the coal. When the drive cylinder retracts, the idlers on both sides of the support frame are horizontally positioned, so that the conveyor belt is straight and can drain the moisture from the coal.

[0007] Preferably, the support frame includes four parallel vertical beams, with two longitudinal beams connected between the top ends of each vertical beam. The longitudinal beams are perpendicular to the conveyor belt transport direction. Two transverse beams are connected between each vertical beam. The transverse beams are arranged along the conveyor belt transport direction. Adjustable idlers are respectively installed at both ends of each longitudinal beam. Each transverse beam is equipped with an operating valve group at both ends. The operating valve group is used to control each drive cylinder.

[0008] Preferably, the adjusting idler includes a folding plate, the plates on both sides of the folding plate are symmetrical to each other, and mounting seats are fixed at both ends of the longitudinal beam. The top corner of the folding plate is rotatably connected to the mounting seat through a rotating shaft, the rotating shaft is parallel to the crossbeam, and clamping plates extend from both ends of the folding plate away from the rotating shaft. Each clamping plate is parallel to the axis of symmetry of the folding plate, and rollers are clamped between each set of clamping plates. Each roller is in contact with the conveyor belt.

[0009] Preferably, two symmetrical tilting limit plates are provided between each mounting base, and a leveling limit plate is provided at the top of each vertical beam. When the conveyor belt is straight, the plate body on the side of each fold plate that is opposite to each other is in contact with the leveling limit plate. When the conveyor belt is concave, the plate body on the side of each fold plate that is close to each other is in contact with the tilting limit plate. Both the tilting limit plate and the leveling limit plate have buffer pads on their contact surfaces.

[0010] Preferably, each crossbeam is equipped with a limiting frame, and the limiting frame is connected to a limiting roller parallel to the vertical beam. The limiting roller can abut against the edge of the conveyor belt.

[0011] Preferably, the plate body on the side of each fold plate that is opposite to each other is provided with a connecting plate, and the connecting plate is rotatably connected to the output end of the drive cylinder.

[0012] Preferably, guide plates are connected between the folding plates arranged along the crossbeam direction. The guide plates are arranged at a certain angle to the rollers. When each conveyor belt is in a straight position, the included angle between each guide plate and the longitudinal beam points to the side away from the conveyor belt.

[0013] Preferably, each vertical beam has a support plate on the side away from the conveyor belt, and the drive cylinder is rotatably connected to the support plate, with the rotation axis of the drive cylinder parallel to the crossbeam.

[0014] Compared to the aforementioned background technology, the conveyor with a coal-water dewatering device provided by this utility model includes a support frame. Adjustable rollers are provided at both the front and rear ends of both sides of the support frame. A conveyor belt is provided between each adjustable roller, with the conveyor belt transporting in the length direction of the support frame. A drive cylinder is connected to one end of each adjustable roller that is opposite to each other. The drive cylinder extends and retracts along the height direction of the support frame, pulling the opposite ends of each adjustable roller, allowing the adjustable rollers to rotate around the length direction of the support frame. When the extension and retraction directions of all drive cylinders are consistent, the rotation directions of the adjustable rollers on both sides of the support frame are the same. Conversely, when each drive cylinder extends, the opposite ends of each adjusting roller are raised, causing the conveyor belt supported on each adjusting roller to be concave. At this time, the conveyor belt can more easily accommodate coal ore, preventing coal ore from scattering off the conveyor belt. When dust-suppressing water mist accumulates on the surface of the conveyor belt to form coal water, the drive cylinder retracts, causing each adjusting roller to be set horizontally. At this time, the conveyor belt is straight, and the water in the coal ore seeps out due to its own weight and the compression of the coal ore. The accumulated water can flow along the conveyor belt to both sides, separating the water accumulated in the coal ore to the outside of the conveyor, completing the dehydration operation of coal water.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] This utility model provides a conveyor with a coal-water dewatering device; please refer to the appendix of the instruction manual. Figure 1 To be continued Figure 3The conveyor with a coal-water dewatering device includes a support frame 4 supporting various components. Adjustable rollers 2 are provided at each end of both sides of the support frame 4, and a conveyor belt 1 is carried on each adjustable roller 2. Each adjustable roller 2 is perpendicular to the length direction of the support frame 4, and the conveyor belt 1 transports along the length direction of the support frame 4. Preferably, each adjustable roller 2 has a drive cylinder 3 connected to its opposite ends. The extension and retraction direction of the drive cylinder 3 is the height direction of the support frame 4, allowing the adjustable roller 2 to rotate around the length direction of the support frame 4. When the drive cylinder 3 extends, the output end of the drive cylinder 3 lifts the opposite ends of the two drive cylinders 3, while the height of the ends that are close together remains unchanged. At this time, the conveyor belt 1 carries the load on each roller 2. The conveyor belt 1 on the adjusting idler 2 is concave. This type of conveyor belt 1 can pick up a larger volume of coal, and the piled coal is not easy to roll off the conveyor belt 1, so that the conveyor has higher conveying efficiency and ensures the reliability of the conveyor. When the length of the drive cylinder 3 is shortened, the height of the opposite ends of each adjusting idler 2 decreases, and each adjusting idler 2 becomes horizontal. Correspondingly, the conveyor belt 1 becomes straight. During the coal transportation process, the water mist used for dust suppression accumulates on the end face of the conveyor belt 1 and forms coal water. The accumulated water flows to both sides of the straight conveyor belt 1 due to its own gravity. The conveyor belt 1 guides the accumulated water to the outside of the conveyor, completing the dehydration operation of the coal water.

[0024] Please refer to the instruction manual appendix. Figure 2 The support frame 4 includes four vertically arranged vertical beams 41. A horizontal beam 42 is connected between two vertical beams 41 along the conveying direction of the conveyor belt 1, and the horizontal beam 42 is located at the midpoint of the vertical beams 41. The two vertical beams 41 connected by the horizontal beam 42 are referred to as a vertical beam assembly. A longitudinal beam 43 is also connected between the two sets of vertical beam assemblies. The longitudinal beam 43 is perpendicular to the conveying direction of the conveyor belt 1. Each longitudinal beam 43 is located at the top of each vertical beam 41. An adjusting roller 2 is installed at both ends of each longitudinal beam 43. Preferably, each end of the vertical beam 41 is provided with an operating valve group 7. Each operating valve group 7 is connected to a drive cylinder 3. The operating valve group 7 controls each drive cylinder 3 to extend and retract.

[0025] Please refer to the instruction manual appendix. Figure 3Each adjusting roller 2 includes a mounting base 25 fixed to both ends of the longitudinal beam 43, and a folding plate 21 connected to the mounting base 25. Preferably, the folding plate 21 is a V-shaped plate with symmetrical plate bodies. A rotating shaft is provided at the top corner of the folding plate 21 along the width direction of the folding plate 21, and the rotating shaft is rotatably connected to the mounting base 25. The rotation axis of the rotating shaft is parallel to the cross beam 42. Furthermore, a clamping plate 22 extends from the side of the plate body of each folding plate 21 away from the rotating shaft. The clamping plate 22 is parallel to the symmetry plane of the folding plate 21. A locking groove is provided on each of the two clamping plates 22. A roller 23 is provided between the two clamping plates 22. A locking rod extends along its own axis of the roller 23. The locking rod is rotatably provided in the locking groove. During the operation of the conveyor, the side wall of the roller 23 is in contact with the lower end face of the conveyor belt 1. The roller 23 rotates with the movement of the conveyor belt 1. The roller 23 is used to reduce the resistance encountered by the conveyor belt 1 during the transportation of coal.

[0026] Please refer to the instruction manual appendix. Figure 1 Two symmetrical tilting limit plates 10 are provided on each longitudinal beam 43, and the two tilting limit plates 10 are located between each mounting base 25. Preferably, the thickness of each tilting limit plate 10 gradually decreases towards the side closer to its adjacent mounting base 25, so that the upper end surface of the tilting limit plate 10 is a slope, and the angle between each slope and the longitudinal beam 43 is opposite to each other. When the operator extends the drive cylinder 3, the adjusting rollers 2 at both ends of the longitudinal beam 43 rotate towards the side closer to each other, and the folding plates 21 of the support rollers 23 rotate together. The plates on the side of each folding plate 21 that are close to each other... The body is in contact with the inclined surfaces of each tilt limit plate 10. Correspondingly, each vertical beam 41 is provided with a leveling limit plate 9 at its top. The thickness of the leveling limit plate 9 gradually increases towards the side away from the mounting base 25. The angle between the inclined surfaces of each leveling limit plate 9 and the longitudinal beam 43 is opposite. When the operator shortens the drive cylinder 3, the adjusting rollers 2 at both ends of each longitudinal beam 43 rotate towards the side away from each other. The plate body of each folding plate 21 on the side away from each other is in contact with the inclined surfaces of the leveling limit plate 9. Both the leveling limit plate 9 and the tilt limit plate 10 are used to limit the rotation angle of the adjusting roller 2.

[0027] Preferably, buffer pads are provided on the inclined surfaces of both the leveling limit plate 9 and the tilting limit plate 10 to prevent the folding plate 21 from being damaged during the contact process.

[0028] Preferably, a limiting frame 5 is provided at the midpoint of each crossbeam 42. The limiting frame 5 is parallel to the vertical beam 41. Specifically, the limiting frame 5 can be "E" shaped. The horizontal plate at the lower end of the limiting frame 5 is connected to the crossbeam 42. The remaining two horizontal plates are located on the upper and lower sides of the conveyor belt 1, respectively. A limiting roller 51 is rotatably provided between the remaining two horizontal plates. The side wall of the limiting roller 51 is in contact with the edge of the conveyor belt 1. During the movement of the conveyor belt 1, the limiting roller 51 restricts the movement direction of the conveyor belt 1 to prevent the conveyor belt 1 from deviating during the transportation of coal.

[0029] Please continue to refer to the instruction manual appendix. Figure 3 Each plate 21 is connected to a connecting plate 24 on the side opposite to each other. Preferably, the connecting plate 24 is two parallel long plates. Each long plate has a connecting hole at the end opposite to the plate 21. The output end of the drive cylinder 3 is clamped between the long plates and a pin is inserted in the connecting hole to rotatably connect the output end of the drive cylinder 3 to the connecting plate 24. Preferably, each vertical beam 41 has a support plate 8 on the side wall opposite to the conveyor belt 1. The support plate 8 is perpendicular to the vertical beam 41. The upper end face of the support plate 8 is hinged to the drive cylinder 3. The drive cylinder 3 can swing relative to the support plate 8 so that when the adjusting roller 2 swings, the drive cylinder 3 can move in coordination with it, improving the flexibility of the adjusting roller 2.

[0030] Please see the attached instructions. Figure 4 A guide plate 6 is connected between two folding plates 21 arranged along the extension direction of the crossbeam 42. Preferably, each guide plate 6 is symmetrically arranged on both sides of the support frame 4, and the guide plate 6 is arranged at a certain angle with the adjusting idler roller 2. When each adjusting idler roller 2 is parallel to each other and the conveyor belt 1 is straight, the included angle between the guide plate 6 and the extension line of the longitudinal beam 43 points to the side away from the conveyor belt 1, and the ends of each guide plate 6 that are away from each other extend out of the conveyor belt 1. When the water accumulated on the end face of the conveyor belt 1 flows down from the edges of both sides of the conveyor belt 1, it falls back onto the guide plate 6. Guided by the guide plate 6, the water is collected into the water tanks on both sides of the conveyor. The operator can periodically empty the water in the water tanks to prevent the water from overflowing.

[0031] In one embodiment of this utility model, each operating valve group 7 is connected in series to ensure that the extension and retraction of each drive cylinder 3 connected to it are the same. In actual production, this utility model is continuously arranged for 30 to 50 meters. The operator sends control signals to each operating valve group 7 through the operation button. Each drive cylinder 3 shortens, pulling the adjusting roller 2 away from the end of the conveyor belt 1, so that each adjusting roller 2 is set horizontally. The conveyor belt 1 supported on each adjusting roller 2 changes from a concave shape to a straight shape. Water accumulated on the end face of the conveyor belt 1 can be discharged from the two edges of the conveyor belt 1. Further separation: When the conveyor belt 1 is in a straight state, the operator can continue to shorten the drive cylinder 3 so that the end of the adjusting rollers 2 that is close to each other is slightly higher than the end that is away from each other. At this time, the conveyor belt 1 bulges upward with a certain arc. While ensuring that the coal on the conveyor belt 1 does not roll off, the conveyor belt 1 can guide the accumulated water to flow to both sides, ensuring that the accumulated water is fully separated and improving the dewatering efficiency of water and coal. After the dewatering of water and coal is completed, the operator controls the operating valve group 7 to extend the drive cylinder 3, so that the conveyor belt 1 is concave and the dewatered coal is transported to the coal bunker.

[0032] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0033] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
