Description

Technical Field

[0001] This application relates to tailings dam dust suppression technology, and more particularly to a tailings dam dry beach dust suppression device. Background Technology

[0002] Tailings dam dry beach is a tailings sedimentation surface located between the dam crest and the waterline within a tailings dam, formed by the accumulation of fine-grained mineral processing waste. The mineral processing waste lacks cohesion, and during dry and windy seasons, these fine-grained waste particles easily generate dust under wind action, polluting the surrounding atmosphere.

[0003] Currently, a common dust suppression method for dry tailings ponds is to install a pipeline dust suppression system on the dry tailings pond, spraying dust suppressant into the dry tailings pond through the pipeline to solidify it. However, the systematic pipeline layout makes it inconvenient to treat the dry pond area separately and cannot flexibly suppress dust. Utility Model Content

[0004] This application provides a tailings dam dry beach dust suppression device to solve the problem that the existing pipeline dust suppression method used in tailings dam dry beaches is not convenient for separate treatment of the dry beach area and cannot flexibly suppress dust.

[0005] This application provides a tailings dam dry beach dust suppression device, including a chassis towed by a tractor, the lower end of which is provided with wheels;

[0006] A liquid storage tank and a gearbox are installed at the upper end of the frame;

[0007] The power input end of the gearbox is connected to the rear power output shaft of the tractor via a universal coupling, and the power output end of the gearbox is connected to a liquid pump.

[0008] The inlet end of the pump is connected to the storage tank through an inlet pipe, and the outlet end of the pump is connected to a spray structure through an outlet pipe.

[0009] The liquid spraying structure is located at the rear end of the vehicle frame.

[0010] Optionally, the spray structure includes a spray pipe I located at the rear end of the vehicle frame. The spray pipe I is connected to a lifting mechanism that can move it up and down. The spray pipe I is connected to an outlet pipe via a flexible hose I.

[0011] Both ends of the spray pipe I are fixed with vertically distributed racks, the racks mesh with rotatable incomplete gears, the incomplete gears are fixed with spray pipe II, and the spray pipe II is connected to spray pipe I through elastic hose II.

[0012] Both spray pipe I and spray pipe II are connected to multiple evenly distributed nozzles.

[0013] Optionally, the incomplete gear is rotatably connected to a mounting base, the mounting base is fixedly connected to the rear end of the frame, and the mounting base has two symmetrically vertically distributed sliding grooves fixed on it. The rack is simultaneously inserted into the two sliding grooves and the two sliding grooves are slidably connected.

[0014] Optionally, the mounting base is a hollow structure, and the incomplete gear and rack are both located inside the mounting base.

[0015] Optionally, the lifting mechanism is a hydraulic cylinder, which is vertically fixed to the rear end of the vehicle frame, and the free end of the hydraulic cylinder is fixedly connected to the spray pipe I;

[0016] The hydraulic cylinder is connected to the rear hydraulic output interface of the tractor.

[0017] Optionally, the spray nozzle of the nozzle is located at the lower end of the mounting base.

[0018] Optionally, the storage tank includes a tank body fixed to the upper end of the vehicle frame, and the tank body is provided with a rotatable stirring structure, which is connected to a hydraulic motor.

[0019] The hydraulic motor is connected to the rear hydraulic output interface of the tractor.

[0020] The tailings dam dry beach dust suppression device provided in this application consists of a chassis with wheels at the lower end, which is towed by a tractor. A storage tank and gearbox are mounted on the upper end of the chassis. The power input end of the gearbox is connected to the rear power take-off shaft of the tractor via a universal coupling. A liquid pump is connected to the power output end of the gearbox. The inlet end of the liquid pump is connected to the storage tank via an inlet pipe, and the outlet end of the liquid pump is connected to a spraying structure via an outlet pipe. The spraying structure is located at the rear end of the chassis, allowing the tractor to tow the chassis as it moves along the dry beach during operation. The tractor moves along the track, while its rear power take-off shaft drives a gearbox via a universal coupling. The gearbox then drives a liquid pump, which draws liquid dust suppressant from a storage tank to a spraying structure. This structure then sprays the dust suppressant onto the dry tailings beach. Compared to existing pipeline-based dust suppression methods, this method, which involves spraying the dust suppressant while the tractor is moving, allows for flexible dust suppression based on varying dust conditions on the dry beach. For large tailings ponds with different humidity levels and dust indices, this is a convenient and economical dust suppression method. Furthermore, since the tractor's rear power take-off shaft drives the liquid pump, no additional power unit is needed. The pump's operation can be controlled simply by opening and closing the rear power take-off shaft from the tractor's cab, making it easy to operate. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0030] like Figures 1-5 As shown:

[0031] An embodiment of this application provides a tailings dam dry beach dust suppression device, which includes a frame 1 towed by a tractor, with wheels 2 installed at the lower end of the frame 1.

[0032] The upper part of the frame 1 is equipped with a liquid storage tank 3 and a gearbox 4.

[0033] The power input end of gearbox 4 is connected to the rear power output shaft of the tractor via a universal coupling, and the power output end of gearbox 4 is connected to a liquid pump 5.

[0034] In this embodiment, the connection methods between the universal coupling and the tractor's rear power take-off shaft, the connection methods between the universal coupling and the gearbox 4, and the connection methods between the frame 1 and the tractor are all existing technologies and will not be described in detail.

[0035] The inlet end of the pump 5 is connected to the lower end of the storage tank 3 through the inlet pipe 6, and the outlet end of the pump 5 is connected to the spray structure 8 through the outlet pipe 7.

[0036] The liquid spraying structure 8 is located at the rear end of the frame 1.

[0037] In use, the chassis 1 is connected to the tractor's traction device, and the liquid storage tank 3 contains liquid dust suppressant. The operator drives the tractor, which pulls the chassis 1 across the dry beach. At the same time, the operator starts the tractor's rear power take-off shaft (the method of opening and closing the tractor's rear power take-off shaft is existing technology and will not be described in detail). The tractor's rear power take-off shaft drives the gearbox 4 through a universal coupling. The gearbox 4 drives the liquid pump 5 to work. The liquid pump 5 draws the liquid dust suppressant from the storage tank 3 through the liquid inlet pipe 6, and delivers the liquid dust suppressant to the spraying structure 8 through the liquid outlet pipe 7. The spraying structure 8 sprays the dust suppressant onto the dry beach to suppress dust.

[0038] The tailings dam dry beach dust suppression device provided in this embodiment consists of a frame 1 with wheels 2 at the lower end, which is towed by a tractor. A storage tank 3 and a gearbox 4 are mounted on the upper end of the frame 1. The power input end of the gearbox 4 is connected to the rear power output shaft of the tractor via a universal coupling. A pump 5 is connected to the power output end of the gearbox 4. The inlet end of the pump 5 is connected to the storage tank 3 via an inlet pipe 6, and the outlet end of the pump 5 is connected to a spraying structure 8 via an outlet pipe 7. The spraying structure 8 is located at the rear end of the frame 1. This allows for the spraying of dust suppressant during use, while the frame 1 is being moved by the tractor. The dust suppressant can be sprayed separately according to different dust conditions on the dry beach, providing flexible dust suppression. For large tailings dam dry beaches with varying humidity and dust indices, this is a convenient and economical dust suppression method. In addition, after the tractor's rear power take-off shaft drives the liquid pump 5, not only is there no need to add an extra power unit, but the opening and closing of the liquid pump 5 can be controlled simply by opening and closing the rear power take-off shaft in the tractor's cab, thus making it easy to open and close the liquid pump 5.

[0039] In some embodiments of this application, the spray structure 8 includes a spray pipe I 801 disposed at the rear end of the frame 1. The spray pipe I 801 is connected to a lifting mechanism 802 that can drive it to move up and down. The spray pipe I 801 is connected to the outlet pipe 7 through an elastic hose I 803.

[0040] Both ends of the spray pipe I 801 are fixed with vertically distributed racks 804. The racks 804 mesh with rotatable incomplete gears 805. The incomplete gears 805 are fixed with spray pipe II 806, and spray pipe II 806 is connected to spray pipe I 801 through flexible hose II 807.

[0041] Furthermore, both flexible hose I 803 and flexible hose II 807 are made of rubber corrugated tubing. Both spray pipe I 801 and spray pipe II 806 are made of steel tubing.

[0042] Both spray pipe I 801 and spray pipe II 806 are connected to multiple evenly distributed nozzles 808.

[0043] In use, the lifting mechanism 802 moves the spray pipe I 801 upward, which in turn moves the racks 804 at both ends of the spray pipe I 801 upward. After the racks 804 move upward, they drive the incomplete gear 805 to rotate, which in turn drives the spray pipe II 806 to rotate horizontally. When the spray pipe II 806 is rotated into a horizontal distribution, the movement of the spray pipe I 801 stops. At this time, the two spray pipes II 806 are horizontally distributed, that is, the spray structure 8 is unfolded, which is used to increase the spraying area and thus improve the spraying efficiency. Then the tractor towing frame 1 moves, and at the same time the liquid pump 5 is started. The dust suppressant in the storage tank 3 is pumped into the spray pipe I 801 through the liquid pump 5, and the dust suppressant in the spray pipe enters the spray pipe II 806 through the spray pipe II 806. All the nozzles 808 connected to the spray pipes I 801 and II 806 spray the dust suppressant onto the dry beach at the same time.

[0044] When not in use, the spray pipe I 801 is moved downwards, causing the racks 804 at both ends of the spray pipe I 801 to move downwards. The racks 804 drive the incomplete gear 805 to rotate, and the incomplete gear 805 drives the spray pipe II 806 to rotate vertically. When the spray pipe II 806 is rotated into a vertical distribution, the movement of the spray pipe I 801 is stopped. At this time, the two spray pipes II 806 are vertically distributed, which means that the spray structure 8 is folded. Therefore, when the tailings dam dry beach dust suppression device provided in this embodiment is stored or moved without spraying dust suppressant, the space occupied can be reduced.

[0045] In some embodiments of this application, the incomplete gear 805 is rotatably connected to a mounting base 809, which is fixedly connected to the rear end of the frame 1 to support the incomplete gear 805. Two symmetrically arranged vertically distributed sliding grooves 8010 are fixed on the mounting base 809. The rack 804 is simultaneously inserted into both sliding grooves 8010 and slidably connected to them. The sliding grooves 8010 have a U-shaped groove structure. The two U-shaped grooves 8010 limit and guide the rack 804, improving its stability during vertical movement.

[0046] In some embodiments of this application, the mounting base 809 is a hollow structure, and the incomplete gear 805 and rack 804 are both located inside the mounting base 809 to protect the incomplete gear 805 and rack 804.

[0047] In some embodiments of this application, the lifting mechanism 802 is a hydraulic cylinder, which is vertically fixed to the rear end of the frame 1, and the free end of the hydraulic cylinder is fixedly connected to the spray pipe I 801.

[0048] The hydraulic cylinder is connected to the rear hydraulic output interface of the tractor.

[0049] In this embodiment, the connection method between the hydraulic cylinder and the rear hydraulic output interface of the tractor is existing technology and will not be described in detail.

[0050] In this embodiment, the operator controls the hydraulic cylinder of the tractor's hydraulic system (the method of the operator controlling the hydraulic cylinder of the tractor's hydraulic system is existing technology and will not be described in detail). When the hydraulic cylinder extends, the spray pipe I 801 moves downward, and when the hydraulic cylinder retracts, the spray pipe I 801 moves upward. Moreover, only one hydraulic cylinder is needed to realize the unfolding or folding of the two spray pipes II 806.

[0051] In some embodiments of this application, the spray nozzle of the nozzle 808 is located at the lower end of the mounting base 809 to prevent the nozzle 808 from spraying dust suppressant onto the mounting base 809 and wasting dust suppressant.

[0052] In some embodiments of this application, the liquid storage tank 3 includes a tank body 301 fixed to the upper end of the frame 1, and the tank body 301 is provided with a rotatable stirring structure 302, which is connected to a hydraulic motor 303.

[0053] The hydraulic motor 303 is connected to the rear hydraulic output interface of the tractor.

[0054] Furthermore, the stirring structure 302 includes a rotating shaft, which is rotatably connected to the tank 301 via a bearing. One end of the rotating shaft is connected to a hydraulic motor 303, and stirring blades are fixed on the rotating shaft.

[0055] In this embodiment, the connection method between the hydraulic motor 303 and the rear hydraulic output interface of the tractor is existing technology and will not be described in detail.

[0056] In use, the operator controls the hydraulic motor 303 through the tractor's hydraulic system (the way the operator controls the hydraulic motor 303 through the tractor's hydraulic system is existing technology and will not be described in detail). The hydraulic motor 303 drives the rotating shaft to rotate, which in turn drives the stirring blades to rotate, stirring the dust suppressant in the tank 301, thereby preventing the dust suppressant from settling in the tank 301 and reducing the dust suppression effect.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
