A dust-reducing belt conveyor

Abstract

The present invention relates to the field of belt conveying. The present invention discloses a dust reduction belt conveyor. The problem to be solved by the present invention is that the existing belt conveyors all adopt a dust reduction method of spraying above the nozzle when transporting ore, while the dust in the ore interlayer of the conveyor belt and the bottom of the ore cannot be treated by dust reduction. When the ore is transported to the conveyor vehicle, a large amount of dust can still fly outward, and the dust reduction effect is poor. When the material moves to the bottom of the toggle device under the conveyor belt, the present invention can reciprocate through the swing frame, so that the swing frame can continuously turn over the material on the conveyor belt, thereby allowing large pieces of material and small pieces of material to be dispersed, so that the atomizing nozzle can more comprehensively reduce the dust on the material on the conveyor belt, and the dust generated in the process of dispersing large materials and small logistics can be effectively removed, thereby improving the efficiency of dust reduction.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when transporting minerals or stones, the minerals or stones are put into the discharge hopper on the top of the support frame, and the materials are dropped onto the conveyor belt for transportation through the discharge hopper, and the materials dropped onto the conveyor belt are sprayed with dust by the atomizing nozzle on the top of the sealed shell, so that the materials dropped onto the conveyor belt can be effectively dusted, and as the conveyor belt continuously transports the materials to the side of the dust reduction device, the driving motor drives the driving rod to rotate, the driving rod rotates through the driving gear, and the transmission gear rotates through the transmission belt to drive the rotating disk to rotate, and the rotating disk rotates to make the rotating rod When the material is moved to the bottom of the driving device under the conveyor belt, the swing frame can be extended and contracted in the limit frame. Then, when the material moves to the bottom of the driving device under the conveyor belt, the swing frame can be swung back and forth through the swing frame, so that the swing frame can continuously turn over the material on the conveyor belt, thereby separating large pieces of material from small pieces of material, and allowing the atomizing nozzle to more comprehensively reduce dust on the material on the conveyor belt. The dust generated in the process of separating large materials from small logistics can be effectively removed, thereby improving the efficiency of dust reduction.

[0014] In the present invention, when the driving motor drives the driving rod to rotate, and the transmission gear rotates under the drive of the driving gear, the articulated frame hingedly arranged on the end surface of the transmission gear will pull the adjusting frame on the adjusting member to deflect. When the adjusting frame deflects on the fixed rod, the other end of the adjusting frame away from the fixed rod will move toward the bottom of the conveyor belt. At this time, the support rod at the other end of the adjusting frame will move downward. During the downward movement of the support rod, the limiting wheel on the adjusting plate is in the limiting groove in the sealing shell. At this time, under the restriction of the limiting groove, the limiting wheel will be driven to deflect the adjusting plate. The deflection of the adjusting plate will drive the support rod to rotate. The rotation of the support rod will The support baffle will be deflected, and the support baffle above the conveyor belt and horizontally arranged with the conveyor belt will gradually tilt during the downward movement, so that the spray head on the support baffle is tilted to spray the material. Through this setting and the toggle device, when the toggle device toggles the material, the angle of the spray head sprays toward the gap between the materials for dust reduction treatment, so that the material on the conveyor belt can not only reduce the dust on the surface of the material, but also reduce the dust in the gaps between the materials, which effectively solves the problem that the dust in the gaps between the materials is difficult to handle.

[0015] In the present invention, when the driving motor drives the driving rod to rotate, the cam on the driving rod will contact the interference wheel on the sliding rod. When the raised end of the cam contacts the interference wheel, it will drive the sliding rod to press down. When the sliding rod moves down, the sliding rod will drive the sliding frame to move through the mounting frame and the welding plate. At this time, the sliding frame moves down in the slot plate, and the rotating half-tooth at the end of the rotating rod on the sliding frame will contact the limiting rack, and then the rotating half-tooth will rotate under the restriction of the limiting rack. The rotation of the rotating half-tooth drives the rotating rod to rotate, and the rotating rod will drive The wind direction plate swings back and forth. At this time, the wind direction plate will swing back and forth during the process of moving up and down above the conveyor belt, so that the dust on the conveyor belt can be blown away in multiple directions. The direction of the wind is set in the direction of the spray head. Then, when the spray head performs dust reduction treatment on the material, the wind is driven by the setting of the wind direction plate to blow the dust on the conveyor belt toward the direction of the spray head, so that the spray head can have a better dust reduction effect on the dust, and the dust on the conveyor belt can be further treated by dust reduction, thereby improving the efficiency of the dust reduction treatment.

[0031] When transporting minerals or stones, the minerals or stones are put into the discharge hopper 13 on the top of the support frame 12, and the materials are dropped onto the conveyor belt 11 for transportation through the discharge hopper 13. The materials dropped onto the conveyor belt 11 are sprayed by the atomizing nozzle 15 on the top of the sealed shell 14 to reduce dust, so that the materials dropped onto the conveyor belt 11 can be effectively reduced in dust. As the conveyor belt 11 continuously transports the materials to the side of the dust reduction device 2, the driving rod 22 is driven by the driving motor 21 to rotate, and the driving rod 22 rotates through the driving gear 25 to rotate the transmission gear 24 on the driving member 23, and the transmission gear 24 rotates through the transmission belt 33 to drive the rotating disk 32 to rotate, and the rotating disk 32 rotates to make the rotating rod When the material is moved to the bottom of the driving device 3 by the conveyor belt 11, the swing frame 38 can be used to turn the material on the conveyor belt 11, thereby separating the large pieces of material from the small pieces of material, so that the atomizing nozzle 15 can more comprehensively reduce the dust on the material on the conveyor belt 11, and the dust generated in the process of separating the large materials from the small materials can be effectively removed, thereby improving the dust reduction efficiency.

[0032] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the dust suppression device 2 also includes a spraying device 4 arranged on the inner walls of both sides of the sealed housing 14, the spraying device 4 includes a fixed rod 41 fixedly connected to the inner wall of the sealed housing 14, an adjusting frame 42 is rotatably arranged on the fixed rod 41, an articulated frame 43 is hingedly arranged on the end surface of the transmission gear 24, the articulated frame 43 is hingedly matched with the outer wall of the adjusting frame 42, and an adjusting member 5 is also arranged on the end of the adjusting frame 42 away from the fixed rod 41;

[0033] The adjusting member 5 comprises a support rod 51 rotatably arranged on the adjusting frame 42, an adjusting plate 52 is fixedly connected to one end of the support rod 51 facing the inner wall of the sealing housing 14, a limiting wheel 53 is rotatably arranged on the adjusting plate 52, a limiting groove 54 is provided on the inner wall of the sealing housing 14, the limiting wheel 53 is located in the limiting groove 54, a supporting baffle 55 is fixedly connected to the other end away from the adjusting plate 52 between the two support rods 51, and a spray head 56 is arranged on the supporting baffle 55;

[0034] When the driving motor 21 drives the driving rod 22 to rotate, and the transmission gear 24 rotates under the drive of the driving gear 25, the articulated frame 43 hingedly arranged on the end surface of the transmission gear 24 will pull the adjustment frame 42 on the adjustment member 5 to deflect. When the adjustment frame 42 deflects on the fixed rod 41, the other end of the adjustment frame 42 away from the fixed rod 41 will move toward the bottom of the conveyor belt 11. At this time, the support rod 51 at the other end of the adjustment frame 42 will move downward. During the downward movement of the support rod 51, the limiting wheel 53 on the adjustment plate 52 is in the limiting groove 54 in the sealing shell 14. At this time, under the restriction of the limiting groove 54, the limiting wheel 53 will be driven to deflect the adjustment plate 52, and the deflection of the adjustment plate 52 will drive the support rod 51 to move downward. When the rod 51 rotates, the support rod 51 rotates, which will cause the support baffle 55 to deflect. The support baffle 55 that is located above the conveyor belt 11 and is horizontally arranged with the conveyor belt 11 will gradually tilt during the downward movement, so that the spray head 56 on the support baffle 55 is tilted to spray the material. Through this arrangement and the shifting device 3, when the shifting device 3 shifts the material, the spraying angle of the spray head 56 is toward the gap between the materials for dust reduction treatment, so that the material on the conveyor belt 11 can not only reduce the dust on the surface of the material, but also reduce the dust in the gap between the materials during the dust reduction treatment, which effectively solves the problem that the dust in the gap between the materials is difficult to handle.

[0035] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Fig. 9 As shown, the dust reduction device 2 also includes an air outlet device 6 relatively arranged on the inner wall of the sealed shell 14, the air outlet device 6 includes a sliding rod 61 slidably arranged on the inner wall of the sealed shell 14, the top of the sliding rod 61 is fixedly connected with a mounting frame 62, and a resistance wheel 63 is rotatably arranged on the mounting frame 62, and a pressure spring 64 is sleeved on the sliding rod 61, and the two ends of the pressure spring 64 are respectively connected to the bottom of the mounting frame 62 and the inner wall of the sealed shell 14, and a cam 65 that resists and cooperates with the resistance wheel 63 is arranged on the driving rod 22, and the dust reduction device 2 also includes a swinging member 7 relatively arranged on the inner wall of the sealed shell 14;

[0036] The swing member 7 includes a slot plate 71 fixedly connected to the inner wall of the sealing shell 14, a sliding frame 72 is slidably arranged in the slot plate 71, a rotating rod 73 is rotatably arranged on the sliding frame 72, a rotating half-tooth 74 is fixedly connected to the rotating rod 73, a limiting rack 75 meshing with the rotating half-tooth 74 is fixedly connected to the inner wall of the slot plate 71, a welding plate 76 is extended from the mounting frame 62 toward the sliding frame 72, the welding plate 76 is fixedly connected to the sliding frame 72, and a wind deflector 77 is fixedly connected between the two rotating rods 73;

[0037] When the driving motor 21 drives the driving rod 22 to rotate, the cam 65 on the driving rod 22 will contact the contact wheel 63 on the sliding rod 61. When the raised end of the cam 65 contacts the contact wheel 63, the sliding rod 61 will be pressed down. When the sliding rod 61 moves down, the sliding rod 61 will drive the sliding frame 72 to move through the mounting frame 62 and the welding plate 76. At this time, the sliding frame 72 moves down in the slot plate 71, and the rotating half-tooth 74 at the end of the rotating rod 73 on the sliding frame 72 will contact the limiting rack 75, and then the rotating half-tooth 74 will rotate under the restriction of the limiting rack 75, and the rotating half-tooth 74 will rotate to drive the rotating rod 73 Rotate, the rotating rod 73 will drive the wind deflector 77 to swing back and forth, and at this time, the wind deflector 77 will swing back and forth during the process of moving up and down above the conveyor belt 11, so that the dust on the conveyor belt 11 can be blown away in multiple different directions, and the direction of the wind is set in the direction of the spray head 56. Then, when the spray head 56 performs dust reduction treatment on the material, the wind is driven by the setting of the wind deflector 77 to blow the dust on the conveyor belt 11 toward the direction of the spray head 56, so that the spray head 56 can have a better dust reduction effect on the dust, and can further perform dust reduction treatment on the conveyor belt 11, thereby improving the efficiency of the dust reduction treatment.

[0038] The use method and advantages of the present invention: The use method of the dust reduction belt conveyor, the working process is as follows:

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9As shown in the figure: when transporting minerals or stones, the minerals or stones are put into the discharge hopper 13 on the top of the support frame 12, and the materials are dropped onto the conveyor belt 11 for transportation through the discharge hopper 13, and the materials dropped onto the conveyor belt 11 are sprayed by the atomizing nozzle 15 on the top of the sealed shell 14 to reduce dust, so that the materials dropped onto the conveyor belt 11 can be effectively reduced in dust. As the conveyor belt 11 continuously transports the materials to the side of the dust reduction device 2, the driving motor 21 drives the driving rod 22 to rotate, and the driving rod 22 rotates through the driving gear 25 to rotate the transmission gear 24 on the driving member 23, and the transmission gear 24 rotates through the transmission belt 33 to drive the rotating disk 32 to rotate, and the rotating disk 32 rotates to make the rotating disk 32 rotate. The movable rod 31 rotates, and the rotating frame 34 provided at the other end of the rotating rod 31 pulls the hinged connecting rod 37 to make the connecting frame 36 swing back and forth, and the connecting frame 36 makes the swing frame 38 swing back and forth through the connecting rod 35, and the swing frame 38 extends and contracts in the limit frame 39 when swinging back and forth, and then when the material moves to the bottom of the toggle device 3 under the conveyance of the conveyor belt 11, the swing frame 38 can swing back and forth, so that the swing frame 38 can continuously turn over the material on the conveyor belt 11, so that large pieces of material and small pieces of material can be dispersed, so that the atomizing nozzle 15 can more comprehensively reduce the dust of the material on the conveyor belt 11, and the dust generated in the process of dispersing large materials and small materials can be effectively removed, thereby improving the efficiency of dust reduction;

[0040] When the driving motor 21 drives the driving rod 22 to rotate, and the transmission gear 24 rotates under the drive of the driving gear 25, the articulated frame 43 hingedly arranged on the end surface of the transmission gear 24 will pull the adjustment frame 42 on the adjustment member 5 to deflect. When the adjustment frame 42 deflects on the fixed rod 41, the other end of the adjustment frame 42 away from the fixed rod 41 will move toward the bottom of the conveyor belt 11. At this time, the support rod 51 at the other end of the adjustment frame 42 will move downward. During the downward movement of the support rod 51, the limiting wheel 53 on the adjustment plate 52 is in the limiting groove 54 in the sealing shell 14. At this time, under the restriction of the limiting groove 54, the limiting wheel 53 will be driven to deflect the adjustment plate 52, and the deflection of the adjustment plate 52 will drive the support rod 51 to move downward. The rod 51 rotates, and the support rod 51 rotates, which causes the support baffle 55 to deflect. The support baffle 55 above the conveyor belt 11 and arranged horizontally with the conveyor belt 11 will gradually tilt during the downward movement, so that the spray head 56 on the support baffle 55 is tilted to spray the material. Through this arrangement and the shifting device 3, when the shifting device 3 shifts the material, the spraying angle of the spray head 56 is toward the gap between the materials for dust reduction treatment, so that the material on the conveyor belt 11 can not only reduce dust on the surface of the material, but also reduce dust in the gap between the materials, which effectively solves the problem that dust in the gap between the materials is difficult to handle;

[0041] When the driving motor 21 drives the driving rod 22 to rotate, the cam 65 on the driving rod 22 will contact the contact wheel 63 on the sliding rod 61. When the raised end of the cam 65 contacts the contact wheel 63, the sliding rod 61 will be pressed down. When the sliding rod 61 moves down, the sliding rod 61 will drive the sliding frame 72 to move through the mounting frame 62 and the welding plate 76. At this time, the sliding frame 72 moves down in the slot plate 71, and the rotating half-tooth 74 at the end of the rotating rod 73 on the sliding frame 72 will contact the limiting rack 75, and then the rotating half-tooth 74 will rotate under the restriction of the limiting rack 75, and the rotating half-tooth 74 will rotate to drive the rotating rod 73 Rotate, the rotating rod 73 will drive the wind deflector 77 to swing back and forth, and at this time, the wind deflector 77 will swing back and forth during the process of moving up and down above the conveyor belt 11, so that the dust on the conveyor belt 11 can be blown away in multiple different directions, and the direction of the wind is set in the direction of the spray head 56. Then, when the spray head 56 performs dust reduction treatment on the material, the wind is driven by the setting of the wind deflector 77 to blow the dust on the conveyor belt 11 toward the direction of the spray head 56, so that the spray head 56 can have a better dust reduction effect on the dust, and can further perform dust reduction treatment on the conveyor belt 11, thereby improving the efficiency of the dust reduction treatment.
