Technical Field

[0001] This invention relates to the field of bucket wheel stacker-reclaimer technology, and more specifically to a dust control device for a bucket wheel stacker-reclaimer. Background Technology

[0002] Bucket wheel stacker-reclaimers are large-scale continuous loading and unloading equipment, mainly used for the stacking and reclaiming of bulk materials (such as coal, ore, sand and gravel). They can achieve efficient material stacking and material retrieval from the stockpile, and are key equipment in the automated process of bulk material handling.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0021] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the 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, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 13 As shown, the present invention provides a dust prevention device for a bucket wheel stacker-reclaimer, comprising: a body 1; a bucket wheel body 2 mounted on the body 1; a hopper 3 inserted and mounted on the bucket wheel body 2; and a dust prevention mechanism to prevent dust from overflowing.

[0023] The dust control mechanism includes: a baffle 4 hinged to the hopper 3, with a torsion spring installed at the hinge of the baffle 4 and the hopper 3; a dust suction assembly for removing dust; and a spray assembly for spraying water mist onto the material.

[0024] Multiple hoppers 3 are provided, and the multiple hoppers 3 are distributed in a ring array along the circumference of the bucket wheel body 2.

[0025] Under normal conditions, the torsion spring causes the baffle 4 to close the feed inlet of the hopper 3.

[0026] When the bucket wheel body 2 rotates, it can drive multiple hoppers 3 to rotate, thereby picking up materials. When the hopper 3 picks up materials, the materials squeeze the baffle 4, causing the baffle 4 to deflect into the hopper 3 and causing the torsion spring to deform. At this time, the materials can enter the hopper 3. When the hopper 3 rotates with the bucket wheel body 2, the materials on the baffle 4 fall into the hopper 3. Through the elastic force of the torsion spring, the baffle 4 can be reset, so that the baffle 4 returns to the closed state of the feed inlet of the hopper 3. This avoids the problem of dust being generated and overflowing when the hopper 3 is open after picking up materials as the bucket wheel body 2 rotates.

[0027] The dust collection assembly includes: an annular plate 5 rotatably mounted inside the bucket wheel body 2, and the annular plate 5 is fixedly mounted on the machine body 1 by a mounting bracket (not shown); a guide cover 8 inserted and mounted on the annular plate 5; a processing box 9 fixedly mounted on the machine body 1; a fixing box 6 inserted and mounted on the processing box 9; a guide pipe 7 connecting the guide cover 8 and the fixing box 6; a filter box 12 fixedly mounted on the processing box 9; a filter screen 13 fixedly mounted inside the filter box 12; an air collecting hopper 10 fixedly mounted inside the fixing box 6; an air guide pipe 11 connecting the air collecting hopper 10 and the filter box 12; an air pump 14 fixedly mounted on the filter box 12; an air inlet end connecting the air pump 14 and the air inlet pipe 15 connecting the air pump 14 and the air outlet end connecting the air outlet pipe 16 connecting the guide pipe 7.

[0028] The discharge port of hopper 3 is fitted to the outer side of the annular plate 5, thereby avoiding the problem of material leaking out of the discharge port of hopper 3 as hopper 3 rotates with bucket wheel body 2 after material is taken out.

[0029] When the hopper 3, after taking out the material, rotates with the bucket wheel body 2 to the guide cover 8, the discharge port is connected to the guide cover 8, and the material passes through the guide cover 8 and the guide pipe 7 in sequence into the fixed box 6.

[0030] At the same time, the air pump 14 is started to draw air out of the filter box 12, creating a negative pressure inside the filter box 12. This causes the air in the fixed box 6 to enter the filter box 12 sequentially through the air collecting hopper 10 and the air guide pipe 11. After being filtered by the filter screen 13, the air is drawn out by the air pump 14. During this process, the dust in the material delivered to the fixed box 6 is dispersed. At this time, the airflow carries the dust into the filter box 12 for collection, thereby achieving the dust removal process.

[0031] The gas drawn by the air pump 14 is delivered to the feed pipe 7 through the air outlet pipe 16, according to the attached... Figure 8 As can be seen, the air outlet end of the air outlet pipe 16 points to the material outlet end of the guide pipe 7, so the high-pressure airflow generated by the air pump 14 blows towards the material conveying direction. The high-pressure gas can overcome the resistance caused by material suspension and pipe friction, ensuring smooth conveying process, avoiding material accumulation in the guide pipe 7, and improving material conveying efficiency.

[0032] It should be noted that the filter box 12 is equipped with a sealed door (not shown). Opening the sealed door facilitates the removal of dust inside the filter box 12 and the maintenance of the filter screen 13.

[0033] The dust collection assembly also includes: a fixed plate fixedly installed inside the filter box 12; an air collection shell 17 fixedly installed between the fixed plate and the filter box 12; a rotating rod 18 rotatably installed on the air collection shell 17, the rotating rod 18 being rotatably connected to the fixed plate; a brush plate 20 and a fan blade 19 fixedly installed on the rotating rod 18; and the air collection shell 17 being connected to the air outlet pipe 16.

[0034] When the high-pressure airflow generated by the air pump 14 enters the air collection shell 17, it can drive the fan blade 19 to rotate. The fan blade 19 drives the rotating rod 18 to rotate, and the rotating rod 18 drives the brush plate 20 to rotate. The brush plate 20 can clean the dust attached to the air intake side of the filter screen 13, ensuring the filtration effect of the filter screen 13.

[0035] In this invention, the dust collection component can not only perform dust collection on the materials conveyed into the fixed box 6, avoiding the problem of dust overflow and improving the dust prevention effect during material handling, but also blow the high-pressure airflow generated by the air pump 14 towards the material conveying direction. The high-pressure gas can overcome the resistance caused by material suspension and pipe friction, ensuring smooth conveying process, preventing material from accumulating in the guide pipe 7, and improving material conveying efficiency. At the same time, it can clean the dust attached to the air inlet side of the filter screen 13, ensuring the filtration effect of the filter screen 13.

[0036] The spray assembly includes: a fixed pipe 21 and a water tank 24 fixedly installed on the body 1; an inlet pipe 25 connecting the water tank 24 and the fixed pipe 21; a piston plate 23 slidably installed inside the fixed pipe 21; a power source 22 that drives the piston plate 23 to move, the power source 22 being fixedly installed inside the fixed pipe 21; a collection pipe 29 rotatably installed on the treatment tank 9, two of which are symmetrically arranged; multiple nozzles 30 inserted and installed on the collection pipe 29, arranged in a linear array along the axial direction of the collection pipe 29; an installation pipe 27 fixedly installed on the treatment tank 9; an outlet pipe 26 connected to the fixed pipe 21; and a guide pipe 28 connecting the collection pipe 29 and the installation pipe 27.

[0037] Both the inlet pipe 25 and the outlet pipe 26 are equipped with one-way valves to ensure that the water flows unidirectionally through the inlet pipe 25 into the fixed pipe 21 and is discharged through the outlet pipe 26.

[0038] The spray assembly also includes: an adjustment unit for adjusting the direction of water flow; the adjustment unit includes: a slider 32 slidably installed in the mounting tube 27; a second power source 31 for moving the slider 32, the second power source 31 being fixedly installed on the mounting tube 27; a liquid guiding cavity 33 opened on the slider 32; a second liquid guiding pipe 51 communicating with the mounting tube 27; the liquid outlet end of the water outlet pipe 26 is fixedly installed at the liquid inlet end of the liquid guiding cavity 33, and an elongated groove is opened on the mounting tube 27, the water outlet pipe 26 being slidably installed in the elongated groove, thereby facilitating the movement of the water outlet pipe 26 by the slider 32.

[0039] When the body 1 is not in use, the adjustment unit is in the initial state, that is, the liquid inlet end of the liquid guiding cavity 33 on the slider 32 is aligned with the liquid inlet end of the liquid guiding tube 51.

[0040] When the machine body 1 is in use, the dust collection component is activated simultaneously with the spray component. Specifically, by controlling the shortening of the power source 31, the slider 32 is driven to slide within the mounting tube 27, aligning the inlet end of the liquid guiding chamber 33 on the slider 32 with the inlet end of the liquid guiding pipe 28. At this time, the power source 22 is activated, driving the piston plate 23 to move up and down reciprocally within the fixed tube 21. This allows water from the water tank 24 to be transported to the fixed tube 21 through the water inlet pipe 25 and then to the liquid guiding chamber 33 through the water outlet pipe 26. Subsequently, the water is transported to the collection pipe 29 through the liquid guiding pipe 28 and then atomized and sprayed out through multiple nozzles 30. This allows the material in the processing box 9 to come into contact with the water mist, achieving the effect of wetting the material. Dust in the material that has not been removed by the dust collection component mixes with the water mist and adheres to the surface of the material, achieving dust reduction treatment. This prevents the material from falling from the processing box 9 onto the conveyor belt of the machine body 1, thus avoiding the problem of a large amount of dust affecting the working environment of the machine body 1.

[0041] It should be added here that both Power Source 1 22 and Power Source 2 31 are preferably cylinders.

[0042] The adjustment unit also includes: symmetrically opened slide grooves (not shown) in the processing box 9; a linkage bar 43 slidably installed in the slide groove; a movable plate 42 and a rack 44 fixedly installed on the linkage bar 43; a gear 45 meshing with the rack 44; a linkage rod 46 through installed on the mounting tube 27; one end of the linkage rod 46 is fixedly connected to the adjacent linkage bar 43, and the other end of the linkage rod 46 is fixedly connected to the slider 32.

[0043] Two linkage bars 43 are symmetrically arranged, thus two movable plates 42 and two racks 44 are also provided, and two gears 45 are rotatably installed in the processing box 9.

[0044] When the body 1 is not in use, the adjustment unit is in the initial state, that is, the liquid inlet end of the liquid guiding cavity 33 on the slider 32 is aligned with the liquid inlet end of the liquid guiding tube 51; at this time, the two movable plates 42 abut against each other, thereby sealing the bottom opening of the fixed box 6 and preventing the dust remaining in the fixed box 6 from drifting downwards.

[0045] When the machine body 1 is in use, the control power source 2 31 shortens and drives the slider 32 to slide in the mounting tube 27, which can drive the connecting rod 46 to move. The connecting rod 46 drives the connecting bar 43 to move. The connecting bar 43 drives the adjacent movable plate 42 and rack 2 44 to move. The rack 2 44 drives the gear 2 45 to rotate, so that the two movable plates 42 move away from each other. When the liquid inlet end of the liquid guiding cavity 33 on the slider 32 is aligned with the liquid inlet end of the liquid guiding tube 1 28, the two movable plates 42 release the closure of the bottom opening of the fixed box 6. At this time, the material entering the fixed box 6 can enter the processing box 9 through the bottom opening of the fixed box 6, and fall onto the conveyor belt of the machine body 1 through the bottom opening of the processing box 9 for conveying.

[0046] It should be added that by setting two slides, the linkage bar 43 can be limited, so that the linkage bar 43 can maintain linear movement.

[0047] The spray assembly also includes: a gas collecting pipe 34 fixedly installed on the treatment box 9; a second air guide pipe 41 connecting the gas collecting pipe 34 and the fixed pipe 21; a movable rod 36 installed through the gas collecting pipe 34; a second piston plate 35 fixedly installed on one end of the movable rod 36; a movable bar 38 fixedly installed on the other end of the movable rod 36; a return spring 37 that drives the second piston plate 35 to return to its original position, one end of the return spring 37 being fixedly connected to the second piston plate 35, and the other end of the return spring 37 being fixedly connected to the inner wall of the gas collecting pipe 34; a rack 39 fixedly installed on the movable bar 38; a gear 40 meshing with the rack 39; and a gear 40 fixedly sleeved on the liquid collecting pipe 29.

[0048] When piston plate 23 moves downward within fixed tube 21, it compresses the air within fixed tube 21. The air in fixed tube 21 enters gas collecting tube 34 through air guide tube 41, increasing the air pressure within gas collecting tube 34. This causes piston plate 35 to move upward, which in turn causes movable rod 36 to move upward and compresses return spring 37. Movable rod 36 causes movable bar 38 to move upward, which in turn causes two racks 44 to move upward. The two racks 44 cause adjacent gears 45 to rotate, which in turn causes adjacent liquid collecting tube 29 to rotate.

[0049] When piston plate 23 moves upward in fixed tube 21, it can draw air from gas collecting tube 34 into fixed tube 21. At this time, the spring force of return spring 37 can drive piston plate 35 to reset, which can drive rack 44 to reset downward. Rack 44 drives adjacent gear 45 to rotate in the opposite direction, which can drive adjacent liquid collecting tube 29 to rotate in the opposite direction and reset.

[0050] By rotating the collection pipe 29 in both directions, the nozzle 30 can be driven to swing, thereby expanding the spray range and allowing the dust in the treatment box 9 to come into more full contact with the water mist, thus improving the dust suppression effect.

[0051] In this invention, by setting up the spray assembly, on the one hand, the nozzle 30 atomizes and sprays water into the processing tank 9, so that the material in the processing tank 9 comes into contact with the water mist. The dust in the material that has not been removed by the dust collection assembly mixes with the water mist and adheres to the surface of the material, thus achieving dust reduction treatment of the material. This avoids the problem of a large amount of dust generated when the material falls from the processing tank 9 onto the conveyor belt of the machine body 1, which affects the working environment of the machine body 1, and further improves the dust prevention effect when picking up materials. On the other hand, it can drive the nozzle 30 to swing, thereby expanding the spray range, so that the dust in the processing tank 9 comes into more thorough contact with the water mist, and improves the dust reduction effect.

[0052] The dustproof mechanism also includes: a rotating pipe 48 rotatably installed inside the treatment box 9, with the outlet end of the second liquid guide pipe 51 connected to the rotating pipe 48 and rotatably connected to the rotating pipe 48; a rotating plate 47 fixedly sleeved on the rotating pipe 48, with multiple rotating pipes 48 and rotating plates 47; a third power source 50 that drives the rotating pipe 48 to rotate, the third power source 50 being fixedly installed on the treatment box 9, and the output end of the third power source 50 being fixedly connected to the end of any rotating pipe 48; a linkage 49 installed on adjacent rotating pipes 48; a cavity (not shown) is opened inside the rotating plate 47, the cavity being connected to the rotating pipe 48, and a water spray hole 52 is opened on the side wall of the rotating plate 47, the water spray hole 52 being connected to the cavity, with multiple water spray holes 52.

[0053] When the machine body 1 is not in use, all the rotating plates 47 are in a horizontal position, which can close the bottom opening of the processing box 9, preventing residual materials in the processing box 9 from falling and hitting maintenance personnel, thus improving the safety of use.

[0054] When the machine body 1 is in use, the power source 3 50 is started to drive the adjacent rotating tube 48 to rotate. Through the synchronous transmission of the linkage 49, multiple rotating tubes 48 rotate synchronously, thereby causing multiple rotating plates 47 to rotate from a horizontal state to a vertical state.

[0055] Furthermore, during the material handling process, the control power source 350 drives multiple rotating plates 47 to rotate 45 degrees forward from a vertical position, then return to a vertical position, then rotate 45 degrees in the opposite direction, and then return to a vertical position, repeating this process repeatedly. This causes the multiple rotating plates 47 to swing back and forth. At this time, the material falling on the rotating plates 47 falls onto the conveyor belt with the swing of the rotating plates 47. On the one hand, it can spread the material relatively evenly on the conveyor belt, avoiding the problem of material accumulating on the conveyor belt, which would cause the local pressure on the conveyor belt to be too large and accelerate the wear of the conveyor belt. On the other hand, it avoids the material falling directly onto the conveyor belt with a relatively high material difference, reducing the impact on the conveyor belt and avoiding the large amount of dust generated by the material falling directly during the material handling and conveying process.

[0056] When the machine body 1 is finished, the second power source 31 extends and drives the slider 32 to reset, that is, the adjustment unit returns to the initial state. At this time, the liquid inlet end of the liquid guiding cavity 33 on the slider 32 is aligned with the liquid inlet end of the second liquid guiding tube 51, and the two movable plates 42 abut against each other to seal the bottom opening of the fixed box 6.

[0057] At this time, the power source 22 is started to drive the piston plate 23 to move up and down in the fixed pipe 21, so that the water in the water tank 24 can be transported to the fixed pipe 21 through the water inlet pipe 25, and then transported to the cavity of the rotating plate 47 through the water outlet pipe 26, the liquid guiding chamber 33, the liquid guiding pipe 51, and the rotating pipe 48 in sequence, and then sprayed out through the water spray hole 52.

[0058] At the same time, the power source 3 50 is started to drive the rotating pipe 48 to rotate circumferentially, so that multiple rotating plates 47 rotate and spray water at the same time, thereby cleaning the dust attached to the inner wall of the treatment box 9, the rotating plates 47, and other components, thus cleaning the inner wall of the treatment box 9, the rotating plates 47, and other components, preparing for subsequent processes, and after cleaning, the multiple rotating plates 47 are reset to a horizontal state.

[0059] It should be noted that the power source 3 50 is preferably a motor, and the connecting component 49 is preferably a sprocket or chain.

[0060] In this invention, by setting up a dustproof mechanism, on the one hand, the dust in the material can be treated by both suction dust removal and spray dust suppression, so as to avoid the material inside the hopper 3 shaking and generating dust overflow as the bucket wheel body 2 rotates after the material is picked up, which would affect the working environment of the machine body 1. On the other hand, the material can be spread relatively evenly on the conveyor belt, so as to avoid the material falling directly onto the conveyor belt with a relatively high material difference, thereby reducing the impact on the conveyor belt and avoiding the large amount of dust generated by the material falling directly during the material picking and conveying process.

[0061] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
