Description

Technical Field

[0001] This invention relates to the field of belt drive technology, and in particular to a belt drive for processing non-metallic ores. Background Technology

[0002] Non-metallic minerals refer to mineral resources in nature other than metallic minerals and fuel minerals. Compared with metallic minerals, they usually have lower boiling and melting points, are poor conductors of electricity and heat, and have a dull appearance but bright colors. They mainly include diamond, graphite, crystal, corundum, asbestos, marble, granite, and salt minerals.

[0003] Existing belt conveyors often suffer from uneven ore distribution during daily processing, which can easily cause the conveyor belt to deviate from its centerline during operation. This leads to ore drift off the transport line, causing wear and tear on the equipment, and even material spillage, thus shortening its lifespan. Furthermore, non-metallic ores generate significant dust during transport, especially at the discharge point, resulting in severe dust pollution and harm to employee health. Additionally, traditional screw conveyors cannot adaptively adjust to conveyor belt tension, leading to slippage and accelerated wear on the belt and bearings.

[0004] Therefore, this application provides a belt conveyor for non-metallic ore processing to meet the requirements. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide a conveyor belt machine for processing non-metallic ores to address the problems of uneven ore distribution during daily processing, which easily causes the conveyor belt to deviate from the center line during operation, causing the ore to deviate from the transport line, resulting in wear and tear on the equipment, and even material spillage, affecting the life of the equipment. At the same time, during the transportation of non-metallic ores, there is a lot of dust and vibration, especially at the material drop point, where dust flies seriously, polluting the environment and harming the health of employees. This invention solves the problem that traditional screws cannot adaptively adjust according to the tension of the conveyor belt, resulting in slippage and accelerated wear of the belt and bearings.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A conveyor belt conveyor for processing non-metallic ore includes a support frame, characterized in that a conveyor belt frame is fixedly connected to the top of the support frame, a guide shroud is fixedly connected to the top of the conveyor belt frame, a control center is fixedly connected to one end of the guide shroud, a drive motor is fixedly connected to one end of the support frame, a negative pressure dust collection component is fixedly connected inside the guide shroud for absorbing dust on the surface of the ore, and the negative pressure dust collection component is connected to the guide shroud; a deviation correction screening component is used to screen ores of different volumes, and the deviation correction screening component is connected to the conveyor belt frame; and a tension adjustment component is used to adjust the tension of the conveyor belt, and the tension adjustment component is connected to the deviation correction screening component.

[0008] Optionally, the negative pressure dust collection assembly includes a dust collection chamber fixedly connected to the top of the guide hood, a negative pressure exhaust pipe fixedly connected to the top output end of the dust collection chamber, and a collection chamber fixedly connected to the other end of the negative pressure exhaust pipe.

[0009] Optionally, a pull-out box is inserted into the inside of the collection bin, and conical discharge troughs are fixedly connected to the bottom of both ends of the transmission belt frame. Guide pipes are fixedly connected to the bottom of the two conical discharge troughs, and the other ends of the two guide pipes are inserted into the two ends of the collection bin.

[0010] Optionally, multiple jet heads are fixedly connected to the inner walls of both ends of the transmission belt frame. The jet heads are located below the flow guide and the output direction of the jet heads forms a 30-degree angle with the inner wall surface of the transmission belt frame. Multiple sealing curtains are fixedly connected to the end of the flow guide and multiple negative pressure fans are fixedly connected to the top inner wall of the flow guide.

[0011] Optionally, the correction screening assembly includes a honeycomb conveyor belt rotatably connected to the inner wall of the transmission belt frame, and a guide roller is rotatably connected to the inner wall of the transmission belt frame, the guide roller being positioned above the honeycomb conveyor belt.

[0012] Optionally, a fixed base is also fixedly connected to the top of the air guide, a threaded rod is rotatably connected inside the fixed base, a rotating handle is threadedly connected to the top of the threaded rod, a fixed frame is fixedly connected to the bottom of the threaded rod, and a laser scanner is fixedly connected to the top of one end of the air guide.

[0013] Optionally, a graded flow guide plate is fixedly connected to one end of the fixing frame. The graded flow guide plate is triangular, and multiple rotating wheels are rotatably connected to the two end surfaces of the graded flow guide plate. The two ends of the graded flow guide plate are slidably connected to the inner wall of the flow guide shroud.

[0014] Optionally, the tension adjustment assembly includes a detection cavity fixedly connected to the end surface of the transmission belt frame, a hydraulic cylinder fixedly connected inside the detection cavity, a booster block fixedly connected to the output end of the hydraulic cylinder, and the interior of the booster block being a hollow, quincunx-shaped groove.

[0015] Optionally, a rotating rod is sleeved inside the booster block, a sleeve is frictionally connected to the surface of the rotating rod, a plurality of fins are fixedly connected to the surface of the sleeve, and a connecting plate is rotatably connected to the ends of the plurality of fins.

[0016] Optionally, a limiting rod is rotatably connected to the other end of the connecting plate, and a power plate is fixedly connected to the top of the plurality of limiting rods. The surface of the power plate is rotatably connected to the inner wall of the honeycomb conveyor belt, and a limiting frame is slidably connected to one end of the plurality of limiting rods.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above solution, a negative pressure dust collection component is installed. The end of the guide hood is sealed with a sealing curtain, and the dust on the surface of the ore is blown up by a jet head tilted at 30 degrees. The dust is then drawn into the dust collection chamber by a negative pressure fan and finally transported to the collection bin through a negative pressure exhaust pipe. The screened ore is then simultaneously introduced into the collection bin through the cooperation of a conical feeding chute and a guide pipe. The pull-out box facilitates the centralized cleaning and recycling of dust and ore, reducing the problem of dust flying during the transportation of non-metallic ores, protecting the environment, ensuring the health of employees, and realizing the recycling and reuse of dust and collected ore, thereby improving resource utilization.

[0019] By setting up a correction screening component, the honeycomb conveyor belt, in conjunction with guide rollers, transports the ore. Simultaneously, a laser scanner detects the ore distribution and size. Rotating the handle adjusts the threaded rod, causing the grading guide plate to rise and fall. The triangular guide plate and surface rollers gently separate ores of different volumes, guiding oversized ores to the conical feed chute and guide pipe, thus achieving ore grading and screening. Furthermore, the guide rollers balance the load on the honeycomb conveyor belt, preventing conveyor belt deviation and material spillage caused by uneven ore distribution, reducing equipment wear, extending the service life of the transmission belt conveyor, and providing uniformly sized ore raw materials for subsequent processing, thereby improving processing efficiency.

[0020] By setting up a tension adjustment component and using the detection cavity to monitor the load of the honeycomb conveyor belt in real time, the hydraulic cylinder drives the plum blossom-shaped booster block to push the sleeve on the rotating rod. Through the fin plate and connecting plate, the limiting rod slides within the limiting frame, thereby adjusting the support diameter of the power plate on the conveyor belt. This achieves adaptive adjustment of the conveyor belt tension, providing sufficient tension to prevent slippage under load and reducing tension to save energy under no-load conditions. This avoids the limitations of traditional screw adjustment, reduces wear on the belt and bearings, improves the stability and economy of the transmission belt machine, and extends the service life of components.

[0042] As an implementation method in this embodiment, such as Figures 3 to 6As shown, the negative pressure dust collection assembly 6 includes a dust collection chamber 64 fixedly connected to the top of the flow guide hood 3. A negative pressure exhaust pipe 65 is fixedly connected to the top output end of the dust collection chamber 64, and a collection chamber 66 is fixedly connected to the other end of the negative pressure exhaust pipe 65. A pull-out box 67 is inserted into the inside of the collection chamber 66. Conical feed troughs 68 are fixedly connected to the bottom of both ends of the transmission belt frame 2. Guide pipes 69 are fixedly connected to the bottom of the two conical feed troughs 68, and the other ends of the two guide pipes 69 are inserted into the two ends of the collection chamber 66. Multiple jet nozzles 62 are fixedly connected to the inner walls of both ends of the transmission belt frame 2. The jet nozzles 62 are located below the flow guide hood 3, and the output direction of the jet nozzles 62 forms a 30-degree angle with the inner wall surface of the transmission belt frame 2. Multiple sealing curtains 61 are fixedly connected to the end of the guide hood 3, and multiple negative pressure fans 63 are fixedly connected to the inner wall of the top of the guide hood 3. The sealing curtains 61 are used to seal the end of the guide hood 3, and the air jet head 62 tilted at 30 degrees blows up the dust on the surface of the ore. The dust is then sucked into the dust collection chamber 64 by the negative pressure fans 63, and finally transported to the collection bin 66 through the negative pressure exhaust pipe 65. Then, through the cooperation of the conical feeding chute 68 and the guide pipe 69, the screened ore is simultaneously introduced into the collection bin 66. The pull-out box 67 facilitates the centralized cleaning and recycling of dust and ore, reduces the problem of dust flying during the transportation of non-metallic ores, protects the environment, protects the health of employees, and realizes the recycling and reuse of dust and collected ore, thereby improving resource utilization.

[0043] As an implementation method in this embodiment, such as Figures 5 to 9 As shown, the correction screening assembly 7 includes a honeycomb conveyor belt 71 rotatably connected to the inner wall of the transmission belt frame 2. A guide roller 72 is also rotatably connected to the inner wall of the transmission belt frame 2, and the guide roller 72 is positioned above the honeycomb conveyor belt 71. A fixed base 73 is fixedly connected to the top of the flow guide shroud 3. A threaded rod 74 is rotatably connected inside the fixed base 73. A rotating handle 75 is threadedly connected to the top of the threaded rod 74. A fixed frame 77 is fixedly connected to the bottom of the threaded rod 74. A laser scanner 76 is fixedly connected to the top of one end of the flow guide shroud 3. A grading guide plate 78 is fixedly connected to one end of the fixed frame 77. The grading guide plate 78 is triangular, and multiple rotating wheels 79 are rotatably connected to both ends of the grading guide plate 78. Both ends of plate 78 are slidably connected to the inner wall of guide shroud 3. The honeycomb conveyor belt 71, in conjunction with guide roller 72, transports the ore. At the same time, laser scanner 76 can detect the distribution and size of the ore. Then, by rotating handle 75 to adjust threaded rod 74, the classifying guide plate 78 is raised and lowered. The triangular guide plate and surface wheel 79 can gently separate ores of different volumes, guiding oversized ores to conical feed chute 68 and guide pipe 69, thus realizing the classification and screening of ore. The guide roller 72 also balances the load of honeycomb conveyor belt 71, avoiding conveyor belt deviation and material spillage caused by uneven ore distribution, reducing equipment wear, extending the service life of the transmission belt machine, and providing uniform ore raw materials for subsequent processing, thereby improving processing efficiency.

[0044] As an implementation method in this embodiment, such as Figures 6 to 11 As shown, the tension adjustment assembly 8 includes a detection cavity 81 fixedly connected to the end surface of the transmission belt frame 2. A hydraulic cylinder 82 is fixedly connected inside the detection cavity 81. A booster block 83 is fixedly connected to the output end of the hydraulic cylinder 82. The inside of the booster block 83 is a hollow, quincunx-shaped groove. A rotating rod 84 is sleeved inside the booster block 83. A sleeve 85 is frictionally connected to the surface of the rotating rod 84. Multiple fins 86 are fixedly connected to the surface of the sleeve 85. A connecting plate 87 is rotatably connected to the ends of the multiple fins 86. A limit rod 88 is rotatably connected to the other end of the connecting plate 87. A power plate 89 is fixedly connected to the top of the multiple limit rods 88. The surface of the power plate 89 is flush with the inner surface of the honeycomb conveyor belt 71. The wall is rotated and connected, with one end of multiple limit rods 88 slidably connected to a limit frame 810. The load of the honeycomb conveyor belt 71 is monitored in real time by the detection cavity 81. The hydraulic cylinder 82 drives the plum blossom-shaped pusher block 83 to push the sleeve 85 on the rotating rod 84. Through the fin plate 86 and the connecting plate 87, the limit rods 88 slide within the limit frame 810, thereby adjusting the support diameter of the power plate 89 on the conveyor belt. This achieves adaptive adjustment of the conveyor belt tension, providing sufficient tension to prevent slippage under load and reducing tension to save energy under no-load conditions. This avoids the limitations of traditional screw adjustment, reduces wear on belts and bearings, improves the stability and economy of the transmission belt machine, and extends the service life of components.

[0045] The working principle of the technical solution provided by this invention is as follows:

[0046] When the device processes non-metallic ores, the negative pressure dust collection component 6 starts operating first. At this time, the ore begins to move into the guide hood 3 fixedly connected to the top of the conveyor belt frame 2, and then passes through the sealing curtain 61. Multiple air jets 62 begin to blow air onto the ore on the honeycomb conveyor belt 71. At this time, dust on the surface of the ore begins to be stirred up and fills the interior of the guide hood 3. Subsequently, the negative pressure fan 63 is driven to begin absorbing the dust inside the guide hood 3, gradually suppressing the dust on the surface of the ore. The dust absorbed by the negative pressure fan 63 begins to be transported from the inside of the dust collection chamber 64 to the negative pressure exhaust pipe 65. The ore is drawn into the collection bin 66 through the negative pressure exhaust pipe 65 for collection. With the help of the grading guide plate 78 in the correction screening component 7, the ore that does not meet the processing size is transported to both ends of the honeycomb conveyor belt 71 through the grading guide plate 78. Then, it is fed into the conical feeding chute 68 through the openings at both ends of the transmission belt frame 2. At this time, the ore that does not meet the processing size is transported through the conical feeding chute 68 to the guide pipe 69 until the ore material inside moves into the collection bin 66. After the ore processing is completed, the collected ore and ore powder are collected and reused by pulling out the pull box 67 inside the collection bin 66.

[0047] When the ore is processed and conveyed through the honeycomb conveyor belt 71 on the correction screening assembly 7, the laser scanner 76 on the guide shroud 3 first scans the ore material, and then the threaded rod 74 is rotated by the rotating handle 75 on the top of the rotating fixed base 73. As the threaded rod 74 rotates, the fixed frame 77 fixedly connected to the bottom of the threaded rod 74 begins to move together with the grading guide plate 78 fixedly connected to the end. At this time, the movement of the grading guide plate 78 begins to screen the size of the ore running on the honeycomb conveyor belt 71. At this time, the larger sized ore passes through the front end of the grading guide plate 78. The arc-shaped head is pushed and moved to both ends by the honeycomb conveyor belt 71. Then, the ore is gently conveyed to the openings at both ends of the transmission belt frame 2 by the rollers 79 at both ends of the classifying guide plate 78, and then transferred away from the transmission belt frame 2 for collection. At the same time, in order to avoid the ore on the honeycomb conveyor belt 71 from being too heavy at the edges, causing it to deviate and slip, the guide roller 72 rotates at all times to assist in conveying the ore at the edges of the honeycomb conveyor belt 71, reducing the load on the power output end of the honeycomb conveyor belt 71 and improving the service life of the equipment.

[0048] As the equipment continuously conveys ore for processing, the tension adjustment component 8 starts operating. At this time, the detection chamber 81 constantly monitors the load level of the honeycomb conveyor belt 71 on the transmission belt frame 2. When the load on the honeycomb conveyor belt 71 changes, the tension adjustment component 8 starts adjusting the tension in real time, driving the hydraulic cylinder 82 to move the pusher block 83 fixedly connected to the output end. The moving pusher block 83 pushes the sleeve 85 against the rotating rod 84, causing it to move along the rotating rod 84. Subsequently, multiple fins 8... 6 drives multiple rotating connecting plates 87 to rotate. As the connecting plates 87 rotate, the limiting rods 88 rotating on the other end of the connecting plates 87 begin to slide on the limiting frame 810. At this time, the multiple sliding limiting rods 88 drive the power plate 89 fixedly connected to the top to move. As the diameter of the multiple power plates 89 increases, the tension of the honeycomb conveyor belt 71 begins to change, constantly adjusting the tension of the honeycomb conveyor belt 71 to provide sufficient tension to prevent slippage. When unloaded, the tension is reduced to save energy and extend the life of the components.
