Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a double-layer cleaning device for belt conveyors and a belt conveyor. Background Technology

[0002] Belt conveyors, also known as belt conveyors or belt conveyors, are continuous conveying machines that use a continuous rubber belt as the bearing surface and traction component. They achieve material transfer through the friction drive principle and are suitable for conveying low-abrasive bulk materials such as powders, granules, and small lumps, as well as packaged goods, in horizontal and inclined directions. They are widely used in mining, metallurgy, coal, logistics, food and other industries.

[0003] In the existing technology, most belt conveyors are not equipped with cleaning devices, or use single-layer cleaning devices to clean the conveyor. However, single-layer cleaners do not clean thoroughly, and when cleaning materials containing water, coal slurry is easily scattered under the conveyor, resulting in poor environmental sanitation and requiring time and effort to clean up the scattered coal slurry. Utility Model Content

[0004] The purpose of this invention is to solve the problem that most belt conveyors in the prior art are not equipped with cleaning devices, or use single-layer cleaning devices to clean the conveyor. However, single-layer cleaners do not clean thoroughly, and when cleaning materials containing water, coal slurry is easily scattered under the conveyor, resulting in poor environmental sanitation and requiring time and effort to clean up the scattered coal slurry.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-layer cleaning device is designed, including a support frame. Two head rollers are rotatably connected to both sides of the inner wall of the support frame. A conveyor belt is drivenly connected to the outer walls of the two head rollers. A cleaning assembly is arranged below the support frame, and a discharge assembly is arranged below the cleaning assembly. The discharge assembly includes a receiving chute, which is located below the conveyor belt. Fixing frames are fixedly connected to both sides of the top of the receiving chute, and the fixing frames are fixedly connected to the support frame.

[0007] In a preferred embodiment, the discharge assembly further includes a receiving pipe, which is fixedly connected to the bottom end of the receiving chute, and the inner wall of the receiving chute is provided with an inclined surface.

[0008] In a preferred embodiment, the discharge assembly further includes a connecting water pipe, which is fixedly connected to the outer wall of one end of the receiving chute. A water supply pipe is fixedly connected to the end of the connecting water pipe away from the receiving chute, and chute spray heads are fixedly connected at equal intervals to the end of the connecting water pipe near the receiving chute. The chute spray heads penetrate one end of the receiving chute and are fixedly connected to the receiving chute.

[0009] In a preferred embodiment, the cleaning assembly includes a fixed limiting frame, which is fixedly connected to the bottom end of the bracket. The fixed limiting frames are provided with a first sliding groove on the side that is close to each other, and a second sliding groove is provided in the middle of the side that is far apart from each other.

[0010] In a preferred embodiment, the cleaning assembly further includes a lead screw, which is rotatably connected to fixed blocks at both ends of the bracket, and a turntable is fixedly connected to the top end of the lead screw.

[0011] In a preferred embodiment, the outer wall of the lead screw is threaded with a support adjustment plate, and the support adjustment plate is slidably connected to the second slide groove. Buffer springs are fixedly connected at equal intervals at the top of the support adjustment plate.

[0012] In a preferred embodiment, the end of the buffer spring away from the support adjustment plate is fixedly connected to a connector, and the connector is slidably connected to the first slide groove. The ends of the two connectors that are close to each other are fixedly connected to a connecting plate. Double-layer scrapers are fixedly connected to both sides of the top of the connecting plate, and the double-layer scrapers are slidably connected to the conveyor belt.

[0013] Another belt conveyor is designed, which includes any of the above-described double-layer cleaning devices.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention features a cleaning assembly. By gripping and rotating the turntable, the lead screw drives the support adjustment plate to slide within the second chute. The buffer spring is compressed by the movement of the support adjustment plate, pushing the connector head and causing it to slide within the first chute. This adjusts the position of the two double-layer scrapers, ensuring they are in contact with the surface of the conveyor belt. The first double-layer scraper can clean over 90% of the material on the conveyor belt surface, while the second double-layer scraper cleans the remaining material. The cleaned material falls into a receiving chute, where water spray nozzles collect it back into the production system, thus avoiding manual cleaning and reducing the labor intensity of employees.

[0025] In this embodiment, the turntable 39 is rotated, and the lead screw 38 drives the support adjustment plate 37 to slide in the second slide groove 321 under the rotation of the turntable 39. The buffer spring 36 fixed on the support adjustment plate 37 is compressed under the sliding of the support adjustment plate 37, pushing the connector 35, so that the connector 35 slides in the first slide groove 32, and the position of the two double-layer scrapers 34 is adjusted so that the double-layer scrapers 34 are in contact with the surface of the conveyor belt 1. The conveyor belt 1 connected to the head roller 11 runs under the rotation of the head roller 11 and generates friction with the two double-layer scrapers 34. The first double-layer scraper 34 can clean more than 90% of the material on the surface of the conveyor belt 1, and the second double-layer scraper 34 cleans the remaining part on the surface of the conveyor belt 1 again, which facilitates the comprehensive cleaning of the surface of the conveyor belt 1.

[0026] Please see Figure 1 , Figure 2 as well as Figure 4 The cleaning assembly includes a fixed limiting frame 31, which is fixedly connected to the bottom of the support 12. A first sliding groove 32 is provided on the side of the fixed limiting frame 31 that is close to each other, and a second sliding groove 321 is provided in the middle of the side of the fixed limiting frame 31 that is far from each other. The cleaning assembly also includes a lead screw 38, which is rotatably connected to fixed blocks at both ends of the support 12. A turntable 39 is fixedly connected to the top of the lead screw 38. A support adjusting plate 37 is threadedly connected to the outer wall of the lead screw 38, and the support adjusting plate 37 is slidably connected to the second sliding groove 321. Buffer springs 36 are fixedly connected at equal intervals to the top of the support adjusting plate 37. A connector 35 is fixedly connected to the end of the buffer spring 36 away from the support adjusting plate 37, and the connector 35 is slidably connected to the first sliding groove 32. A connecting plate 33 is fixedly connected to the end of the two connectors 35 that is close to each other. Double-layer scrapers 34 are fixedly connected to both sides of the top of the connecting plate 33, and the double-layer scrapers 34 are slidably connected to the conveyor belt 1.

[0027] In this embodiment, the swept material falls into the receiving chute 21. The inclined plane 27 ensures that the material falls accurately to the bottom of the receiving chute 21. The water supply pipe 25 is connected to a water tank. The chute spray head 26, which is fixed on the connecting water pipe 24, sprays the water supplied by the water supply pipe 25 into the receiving chute 21. This allows the material in the receiving chute 21 to be recycled to the production system for storage and processing through the receiving pipe 22, facilitating the comprehensive collection and processing of the material.

[0028] Working principle: First, hold the turntable 39 and rotate it. The lead screw 38 drives the support adjustment plate 37 to slide in the second slide groove 321 under the rotation of the turntable 39. The buffer spring 36 fixed on the support adjustment plate 37 is compressed under the sliding of the support adjustment plate 37, which pushes the connector 35, so that the connector 35 slides in the first slide groove 32, and adjusts the position of the two double-layer scrapers 34 so that the double-layer scrapers 34 are in contact with the surface of the conveyor belt 1.

[0029] Next, the conveyor belt 1 connected to the head roller 11 rotates under the rotation of the head roller 11, and rubs against the two double-layer scrapers 34. The first double-layer scraper 34 can clean more than 90% of the material on the surface of the conveyor belt 1. The second double-layer scraper 34 cleans the remaining part on the surface of the conveyor belt 1 again. The cleaned material falls into the receiving chute 21. The inclined angle of the inclined plane 27 makes the material fall accurately into the bottom of the receiving chute 21. The water supply pipe 25 is connected to a water tank. The chute spray head 26 fixed on the connecting water pipe 24 sprays the water supplied by the water supply pipe 25 into the receiving chute 21, so that the material in the receiving chute 21 is recycled to the production system for storage and processing through the receiving pipe 22. This facilitates the comprehensive and convenient cleaning and recycling of the material on the conveyor belt 1 and reduces the labor intensity of the workers.

[0030] In addition, this utility model also provides a belt conveyor, which includes any of the above-described double-layer cleaning devices.
