Description

Technical Field

[0001] This application relates to the field of belt conveyor return material recycling technology, and in particular to a belt conveyor return material recycling device. Background Technology

[0002] In the field of material handling, belt conveyors are widely used as core conveying equipment in various industrial production scenarios. However, during actual operation, material adheres to the surface of the conveyor belt's cover layer. Then, when the upper cover layer moves to the lower cover layer, due to material adhesion, equipment vibration, or impact, the material falls onto the frame platform and the material accumulation area above the branch funnel due to gravity. Simultaneously, material around the funnel feeding system falls onto the dock, causing pollution to the equipment and dock, and increasing the workload of cleanup. To reduce the workload of cleaning up spilled material and to take effective measures to recover the spilled material, a feasibility study was conducted on a material recovery device around the belt conveyor and large funnel.

[0003] To address the aforementioned material spillage problem, existing technology has improved the process by laying a cloth under the conveyor belt to catch the material spilled during transport. While this arrangement can collect spilled material, it makes cleaning the space under the conveyor belt difficult, and it is also difficult to shovel the cleaned material back onto the conveyor belt, which is not conducive to material recycling. Summary of the Invention

[0004] In order to recover materials spilled from belt conveyors, this application provides a belt conveyor return material recovery device.

[0005] The belt conveyor return material recycling device provided in this application adopts the following technical solution: A conveyor belt return material recycling device includes a conveyor located below the conveyor belt along its length. A cleaning mechanism is located at the bottom of the conveyor, and a receiving mechanism is located below the cleaning mechanism. The cleaning mechanism is used to scrape off the material adhering to the conveyor belt, and the receiving mechanism is used to catch the material falling from the conveyor belt.

[0006] By adopting the above technical solution, the material adhering to the lower cover layer of the belt conveyor during the belt conveyor transportation process will fall onto the conveyor due to mechanical vibration and gravity. The conveyor will transport the fallen material to the cleaning mechanism, and the material cleaned by the cleaning mechanism will finally fall to the receiving mechanism, forming a recycling system. This design can effectively collect the material spilled during the operation of the belt conveyor, avoid the material from scattering on the ground, frame platform and the top of the branch funnel, causing pollution and waste, reduce material spillage and prevent material from spilling onto the platform frame, not affect material conveying, reduce the amount of cleaning work and facilitate material recycling.

[0007] Optionally, the conveyor includes a mounting frame, a conveyor belt, and a fixing frame. The mounting frame is fixedly connected to the belt conveyor, and the fixing frame is fixedly connected to the belt conveyor. The mounting frame is provided with a first rotating roller, and the fixing frame is provided with a second rotating roller. The conveyor belt is wound around the first rotating roller and the second rotating roller. Idler rollers are provided below both the upper and lower cover layers of the conveyor belt. The idler rollers are fixedly connected to the belt conveyor. The mounting frame is provided with a drive assembly for driving the first rotating roller to rotate.

[0008] By adopting the above technical solutions, the design of the simple conveyor is compatible with the belt conveyor used. The mounting frame and fixed frame can be set on different equipment, making it widely applicable and not occupying the installation space of other equipment. It is convenient for overall installation and maintenance. The idler support only uses the drive component, two frames, two rollers and idlers to achieve the conveying function. In this way, the design of the simple conveyor is compatible with the belt conveyor used, making it easy to install and maintain. The setting of idlers ensures the stability of the conveyor belt operation.

[0009] Optionally, a first movable seat is rotatably connected to both sides of the first rotating roller, the mounting frame is slidably connected to the first movable seat, the mounting frame is threadedly connected to a first screw, the first screw is arranged along the length direction of the belt conveyor, and the first movable seat is rotatably connected to the first screw.

[0010] By adopting the above technical solution, rotating the first screw drives the first movable seat to move, and the first movable seat drives the first rotating roller to rotate. The tension of the conveyor belt can be easily adjusted through the first screw adjustment mechanism to ensure the normal operation of the conveyor belt.

[0011] Optionally, the drive assembly includes a first motor, which is mounted on the mounting frame. A baffle plate is provided above the first motor, and the first motor controls the first rotating roller via chain drive.

[0012] By adopting the above technical solution, the baffle plate prevents materials from entering the drive component and affecting operation. The chain drives the first rotating roller, which makes it easy to replace the chain of different lengths according to the specific distance. Compared with gear transmission, chain transmission reduces the space occupied.

[0013] Optionally, the conveyor belt material includes PVC / rubber / fiber cloth.

[0014] By adopting the above technical solutions, and selecting the appropriate conveyor belt material according to the material characteristics, the conveying effect and service life can be ensured. Rubber material has a large load-bearing capacity, complex bonding, and long service life, while PVC material is lightweight, has a smooth surface, and is easy to bond.

[0015] Optionally, the cleaning mechanism includes a brush roller and a second motor, the second motor being mounted on the fixed frame and connected to the brush roller, the brush roller being in contact with the surface of the conveyor belt.

[0016] By adopting the above technical solution, the brush roller can effectively remove the material adhering to the conveyor belt, keep the conveyor belt clean, and prevent the material adhering to the conveyor belt from falling directly onto the frame platform when it moves to the lower cover layer. The original cleaning mechanism is a scraper. Compared with the scraper, the brush roller has a better cleaning effect, is less likely to wear the conveyor belt, and the brush roller can be set to be the same width as the conveyor belt, while the original scraper can only be shorter than the width of the conveyor belt.

[0017] Optionally, a second movable seat is slidably connected to the fixed frame, and a second screw is threadedly connected to the fixed frame. The second screw is arranged perpendicular to the length direction of the belt conveyor, and the second screw is rotatably connected to the second movable seat. The second movable seat is rotatably connected to the brush roller.

[0018] By adopting the above technical solution, rotating the second screw pushes the second movable seat, which in turn drives the brush roller to rotate. The contact pressure between the brush roller and the conveyor belt can be adjusted by the screw to ensure the cleaning effect.

[0019] Optionally, the receiving mechanism includes a receiving canvas and a control component. The receiving canvas is disposed below the conveyor belt, and the width of the receiving canvas is not less than the width of the conveyor belt. A mounting bracket is provided on one side of the receiving canvas, and the mounting bracket is mounted on the frame. A support rod is provided on the other side of the receiving canvas, and the support rod is connected to the control component. The control component is used to control the lifting and lowering of the support rod.

[0020] By adopting the above technical solution, the receiving canvas can receive the materials scraped off by the cleaning mechanism, and the control component can realize the raising and lowering of the receiving canvas, making it convenient to place the materials on the dock in a centralized manner, which can realize one-time rapid recycling and centralized cleaning to improve cleaning efficiency.

[0021] Optionally, the mounting bracket is connected to a receiving plate, so that the receiving plate is connected to the receiving canvas, and the receiving plate is located below the grab bucket machine.

[0022] By adopting the above technical solution, the receiving plate is used to catch the material spilled when the grab bucket picks up the material and the material splashed by the brush roller when cleaning the conveyor belt. The design of the connection between the receiving plate and the receiving canvas makes the receiving plate have a certain slope, which facilitates the guidance of the collected material to the receiving canvas.

[0023] Optionally, the control component includes a winch with two steel wires connected to it. A drum is located below the winch, and guide wheels are symmetrically arranged on the drum about the belt conveyor. One of the steel wires passes through the winch, the drum, and the guide wheels in sequence and is connected to the support rod. The other steel wire is directly connected to the support rod. When winding, the two steel wires simultaneously pull the receiving canvas upward.

[0024] By adopting the above technical solution, the winch controls the winding and unwinding of the steel wire, which can realize the lifting and lowering operation of the receiving canvas, making it easier for the receiving canvas to place the material smoothly on the dock.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. During the conveyor belt transportation process, the material adheres to the lower cover layer of the conveyor belt and falls onto the conveyor due to mechanical vibration and gravity. The conveyor transports the fallen material to the cleaning mechanism, and the material cleaned by the cleaning mechanism finally falls to the receiving mechanism, forming a recycling system. This design can effectively collect the material spilled during the operation of the conveyor belt, avoid the material from scattering on the ground, frame platform and the top of the branch funnel, which would cause pollution and waste, reduce material spillage and prevent material from spilling onto the platform and frame, not affect the material conveying, reduce the amount of cleaning work and facilitate material recycling. 2. The brush roller can effectively remove the material adhering to the conveyor belt, keep the conveyor belt clean, and prevent the material adhering to the conveyor belt from falling directly onto the frame platform when it moves to the lower cover layer.

The conveyor 2 is closer to the edge of the frame 8 at the end away from the bifurcation hopper 7 than the conveyor 1. In this embodiment, the conveyor 2 runs in the opposite direction to the conveyor 1. A cleaning mechanism 3 is arranged below the end of the conveyor 2 away from the bifurcation hopper 7. A receiving mechanism 4 is installed on the frame 8. The receiving mechanism 4 is located below the cleaning mechanism 3. The cleaning mechanism 3 is used to scrape off the material on the conveyor 2, and the receiving mechanism 4 is used to receive the material scraped off by the cleaning mechanism 3 and the material spilled from the grab bucket.

[0037] like Figure 2 and Figure 3The conveyor 2 includes a mounting frame 21, a conveyor belt 23, and a fixed frame 22. The mounting frame 21 and the fixed frame 22 are both supported on the frame 8 with a bucket gate. The mounting frame 21 and the fixed frame 22 are both fixed to the belt conveyor 1. Two first movable seats 26 are slidably connected to the mounting frame 21. The two first movable seats 26 are rotatably connected to a first rotating roller 24. A first screw 25 is slidably connected to the first movable seat 26. The first screw 25 is threadedly connected to the mounting frame 21. The first screw 25 is set along the length direction of the conveyor 2. like Figure 2 and Figure 4 A second rotating roller 27 is rotatably connected to the fixed frame 22. A conveyor belt 23 is wound around the first rotating roller 24 and the second rotating roller 27. Two sets of staggered idler rollers 6 are fixed on the belt conveyor 1. One set of idler rollers 6 is located above the other set of idler rollers 6. The two sets of idler rollers 6 are respectively supported at the bottom of the upper and lower cover layers of the conveyor belt 23 to maintain the operation of the conveyor belt 23. In this embodiment, the conveyor belt 23 is made of PVC material. In other embodiments, the conveyor belt 23 can also be made of rubber or fiber cloth.

[0038] like Figure 2 and Figure 3 The mounting frame 21 is equipped with a drive assembly 5, which is used to drive the first rotating roller 24 to rotate. The drive assembly 5 includes a first motor 51. A motor base 54 is welded on the mounting frame 21. The first motor 51 is mounted on the motor base 54. A baffle plate 52 is provided above the first motor 51 to prevent material from spilling into the first motor 51 and affecting its operation. The first motor 51 controls the first rotating roller 24 through a chain 53. A cover plate is provided on the outside of the chain 53 to prevent material from falling onto the chain 53 and causing the chain 53 to jam and malfunction.

[0039] like Figure 4 and Figure 5 Tensioning frames 34 are bolted to both sides of the fixed frame 22. A cleaning mechanism 3 is connected to the tensioning frame 34. The cleaning mechanism 3 is located at the bottom of the second rotating roller 27. The cleaning mechanism 3 includes a brush roller 31. The tensioning frames 34 on both sides are slidably connected to second moving seats 35. The two second moving seats 35 are rotatably connected to the brush roller 31. A second screw 33 is threaded to the tensioning frame 34. The second screw 33 is rotatably connected to the second moving seat 35. Adjusting the second screw 33 makes the brush roller 31 fit tightly against the conveyor belt 23. An extension plate is welded to one side of the fixed frame 22. A second motor 32 is set on the extension plate. The second motor 32 is connected to the brush roller 31. In this embodiment, the second motor 32 is a variable frequency motor with high, medium and low speed adjustment. It can adjust the rotation speed of the brush roller 31 in accordance with the running speed of the conveyor belt 23 and the amount of material flow.

[0040] like Figure 6The receiving mechanism 4 includes a receiving canvas 41 and a control component 45. A mounting support 42 is provided on the frame 8 of the bucket conveyor. The mounting support 42 is connected to the receiving canvas 41. A support rod 44 is connected to the side of the receiving canvas 41 away from the mounting support 42. The support rod 44 is connected to the control component 45. The control component 45 is fixed on the frame 8 and located below the conveyor belt 23. The control component 45 is used to control the lifting and lowering of the support rod 44 to stabilize the receiving canvas 41. The width of the receiving canvas 41 is greater than the width of the conveyor belt 23, so that it can catch the material spilled by the belt conveyor 1. In other embodiments, the support rod 44 can also be replaced by a buckle or a support seat.

[0041] like Figure 6 and Figure 7 The control component 45 includes a winch 451, which is fixed on the frame 8. The winch 451 is connected to two steel wires 454. A roller 452 is provided below the winch 451 and is fixed on the frame 8. Guide wheels 453 are symmetrically arranged on the roller 452 about the belt conveyor 1 and are fixed on the frame 8. One of the steel wires 454 passes through the winch 451, the roller 452 and the guide wheel 453 in sequence and is connected to one end of the support rod 44. The other steel wire 454 is directly connected to the other end of the support rod 44. When winding, the two steel wires 454 simultaneously pull the receiving canvas 41 upward.

[0042] like Figure 6 A receiving plate 43 is connected to the mounting bracket 42. The receiving plate 43 is located below the grab bucket machine. The receiving plate 43 is connected to the receiving canvas 41 through the mounting bracket 42. The receiving plate 43 is set at an angle. The receiving plate 43 catches the material spilled when the grab bucket machine grabs the material. In other embodiments, the receiving plate 43 can be replaced by the receiving canvas 41. The side of the receiving canvas 41 away from the mounting bracket 42 is connected to a steel wire rope and fixed to the frame 8, so that the receiving canvas 41 is set at an angle.

[0043] The implementation principle of this application embodiment is as follows: Before the equipment is started, the position of the first rotating roller 24 is adjusted by the first screw 25 and the first movable seat 26 to ensure the tension of the conveyor belt 23. The speed of the belt conveyor 1 is greater than the speed of the conveyor 2. The second screw 33 and the second movable seat 35 are adjusted so that the brush roller 31 is in close contact with the conveyor belt 23. When the equipment starts up, the grab bucket grabs the material. At this time, the receiving plate 43 receives the material spilled by the grab bucket grabbing the material and guides it into the receiving canvas 41. The grabbed material is then transferred on the belt conveyor 1 to the bifurcated funnel 7. The remaining material will fall onto the conveyor belt 23. When the material adhering to the conveyor belt 23 moves to the edge of the frame 8 near the second rotating roller 27, the brush roller 31 scrapes off the material adhering to the conveyor belt 23. The scraped material falls onto the receiving canvas 41. After each material conveying is completed, the winch 451 controls the steel wire 454 to lower the receiving canvas 41. The material collected by the receiving canvas 41 is placed at the dock for unified cleaning and recycling.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
