DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1 , Figure 2 As shown, a dust removal device for a belt conveyor for coal transportation includes a conveyor belt 1, a protective cover 2, a dust suction pipe 3 and a dust collector 4.

[0020] like Figure 3As shown, the conveyor belt 1 includes a frame 11, a transmission roller 12, an upper guide roller 13, a lower guide roller 14 and a belt piece 15. The frame 11 is tilted and arranged on the ground, and the transmission roller 12 is rotatably connected to both ends of the frame 11. A pair of upper guide rollers 13 are rotatably arranged above the middle position of the frame 11, and a pair of lower guide rollers 14 are rotatably arranged below the middle position of the frame 11. The belt piece 15 is wound around the transmission roller 12, the upper guide roller 13 and the lower guide roller 14, and the middle position is U-shaped to form a dust removal space 16, and the rear of the dust removal space 16 is arranged obliquely upward.

[0021] like Figure 3 As shown, the protective cover 2 is arranged on the frame 11, and the cover is provided with a belt piece 15. The two ends of the protective cover 2 located above the belt piece 15 are respectively provided with a feed port 21 and a discharge port 22. In actual use, protective curtains can be set at the feed port 21 and the discharge port 22 to shield the dust in the protective cover 2.

[0022] like Figure 3 As shown, the dust suction pipe 3 is vertically arranged on the protective cover 2, and the lower end extends into the dust removal space 16. The dust collector 4 is arranged beside the frame 11 and connected to the dust suction pipe 3. The dust collector 4 can be a pulse type or a filtering type to achieve the treatment of smoke and dust.

[0023] like Figure 3 As shown, the top wall of the protective cover 2 is provided with a plurality of air ducts 23, the lower ends of the air ducts 23 are bent toward the dust collection pipe 3 to introduce external wind into the protective cover 2 and carry the dust on both sides to the dust collection pipe 3 for centralized treatment.

[0024] When the coal is transported, the belt 15 is used to transport the coal along the feed port 21 of the protective cover 2 into the protective cover 2. At this time, the dust collector 4 is started, and with the cooperation of the dust suction pipe 3 and the induced draft pipe 23, the dust generated during the transportation process is centrally adsorbed and processed.

[0025] At the same time, when the coal is transported to the dust removal space 16, the coal falls into the dust removal space 16, and the dust on the surface of the coal is knocked off, and then the dust suction pipe 3 absorbs and processes the dust in time. Then the coal continues to be transported on the belt piece 15, passes through the discharge port 22 on the protective cover 2, and is transported along the belt piece 15 to the coal collection area.

[0026] Therefore, by forming a U-shaped dust removal space 16 on the conveyor belt 1, the coal can fall into the dust removal space 16 during transportation, and the dust on the surface of the coal is stirred up, and then the dust generated is promptly adsorbed by the dust suction pipe 3. Finally, the relatively clean coal is further transported along the conveyor belt 1 to the collection area, ensuring that the generation of dust can be reduced when the coal falls to the collection area, thereby protecting the hygiene of the working environment and the health of the staff.

[0027] like Figure 3 As shown, a shock absorbing plate 17 is horizontally arranged on the frame 11 and is located in the dust removal space 16. The shock absorbing plate 17 is arched and hollowed out, and both sides are bent downward. Both ends of the shock absorbing plate 17 are vertically slidably connected to the frame 11, and shock absorbing springs 18 are arranged on the frame 11 to support both ends of the shock absorbing plate 17.

[0028] When the coal falls into the dust removal space 16, the coal first falls on the shock absorbing plate 17, and under the action of the shock absorbing spring 18, the impact force on the coal and the belt piece 15 is reduced, ensuring the long-term and stable operation of the conveyor belt 1. At the same time, the dust on the coal will be shaken off, and then the coal will roll down along the two sides of the shock absorbing plate 17 and fall on the belt piece 15 again, at which time the dust on the surface of the coal will be shaken off again, so as to achieve efficient adsorption and cleaning of the dust on the surface of the coal as much as possible.

[0029] like Figure 3 , Figure 4 As shown, the outer wall of the lower guide roller 14 is rotatably connected with a protective plate 5, which is arranged in an arc shape and contacts the surface of the belt piece 15 on both sides. Therefore, during the operation of the lower guide roller 14, with the cooperation of the protective plate 5, the lower guide roller 14 can be protected while ensuring the stable rotation of the lower guide roller 14, so as to prevent the coal from damaging the lower guide roller 14 and ensure the long-term stable operation of the lower guide roller 14. Rollers 51 are rotatably connected on both sides of the protective plate 5 to reduce the friction between the protective plate 5 and the belt piece 15, prevent the belt piece 15 from being damaged, and enable the protective plate 5 to work stably without affecting the smoothness of the lower guide roller 14.

[0030] like Figure 3 As shown, a cleaning mechanism 6 that contacts the surface of the belt piece 15 is provided at the lower end of the protective cover 2. The cleaning mechanism 6 includes a scraper 61, a cleaning brush 62 and a cleaning cloth 63. The scraper 61 is obliquely arranged in the protective cover 2 and contacts the surface of the belt piece 15. The cleaning brush 62 and the cleaning cloth 63 are arranged in sequence behind the scraper 61 and contact the surface of the belt piece 15.

[0031] After the belt piece 15 has finished transmitting the coal, it will enter the position below the protective cover 2. At this time, the scraper 61 is first used to scrape off the debris on the surface of the belt piece 15, and then the cleaning brush 62 is used to brush the belt piece 15. Finally, the cleaning cloth 63 is used to wipe the belt piece 15 to clean the surface of the belt piece 15 and ensure the cleanliness of the belt piece 15, thereby preventing the belt piece 15 from continuing to work with dust, and further reducing the generation of dust.

[0032] like Figure 3As shown, the cleaning brush 62 and the cleaning cloth 63 are both rotatably connected to the protective cover 2, and the rotation direction is opposite to the movement direction of the belt piece 15, so that the belt piece 15 can be efficiently cleaned. A pulley set 66 is arranged between the cleaning brush 62 and the cleaning cloth 63 and the driving roller 12.

[0033] Therefore, the cleaning brush 62 and the cleaning cloth 63 are driven to rotate by the pulley set 66, and the power of the transmission roller 12 is used as a driving source. There is no need to add an additional driving source, making the working process more convenient.

[0034] like Figure 3 As shown, the cleaning cloth 63 includes a support base 64 and a cloth piece 65 . The cross section of the support base 64 is arranged in a diamond shape, and the cloth piece 65 is arranged at both ends of the support base 64 .

[0035] Therefore, when the cleaning cloth 63 rotates, the tip of the support seat 64 continuously contacts the belt piece 15 and can squeeze and deform the belt piece 15, thereby increasing the pressure of the cloth piece 65 on the belt piece 15, wiping the surface of the belt piece 15 vigorously, improving the cleanliness of the belt piece 15, preventing the belt piece 15 from continuing to work while carrying dust, and further reducing the generation of dust.

[0036] like Figure 3 As shown, a switch opening 24 is provided at the lowest end of the lower end of the protective cover 2 , and a switch mechanism 7 is provided in the switch opening 24 . The switch mechanism 7 includes a switch rod 71 , four switch plates 72 , a locking rod 73 and a locking ring 74 .

[0037] like Figure 3 As shown, the switch rod 71 is horizontally rotatably connected to the switch port 24, and four switch plates 72 are evenly distributed around the switch rod 71, and two adjacent switch plates 72 are used to block the end of the protective cover 2 and the switch port 24. The lock rod 73 is horizontally slidably connected to the lower end surface of the protective cover 2, and the lock ring 74 is arranged on the back side of the switch plate 72 and is plugged into the lock rod 73.

[0038] When cleaning the surface of the belt piece 15, the debris will fall into the protective cover 2 and slide along the bottom wall of the protective cover 2 to the switch opening 24. At this time, the dust is located between two adjacent switch plates 72. Then the lock rod 73 is pulled to disengage the lock ring 74, and then the switch rod 71 is controlled to drive the switch plate 72 to rotate 90 degrees, so that the switch plate 72 carrying the debris is turned out, so that the debris on the switch plate 72 falls off, and the debris is collected.

[0039] And during the collection process, the next switch plate 72 moves to the position of the previous switch plate 72, and then the lock rod 73 is used to insert the lock ring 74 to fix it, and the debris is continued to be received, which will not affect the collection of the debris, and there is no need to stop the machine for cleaning, thereby ensuring the continuous operation of the belt conveyor.

[0040] The specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
