Description
Technical Field
[0001] This utility model relates to the field of dust recovery technology, specifically to a dust collection device and its conveyor belt suitable for dust recovery. Background Technology
[0002] With industrial development, the availability of rich ores directly usable in blast furnaces is decreasing. Mined lean ores must undergo beneficiation and powder agglomeration before smelting. Using artificially produced rich ores (sintered ore, pellets) in blast furnaces can increase output, reduce fuel consumption, rationally utilize resources, and save production costs. Sintering is an indispensable part of the entire steel industry. When batching mineral powders, the mixed powder (containing iron) is typically placed at the end of the belt conveyor, followed by fuel, quicklime, return ore, limestone, and dolomite. This arrangement reduces material adhesion to the conveyor belt, facilitates centralized dust removal, and minimizes mineral powder loss and fluctuations in usage.
[0003] However, even after centralized dust removal, the material still needs to travel a certain distance to reach the mixer. Since the top layer of limestone and dolomite is dry and powdery, it easily generates dust during this transport process, scattering onto the planes on both sides of the conveyor belt. This results in a white layer of flux powder on the ground and severe heavy dust in the air, causing both material waste and environmental pollution. Therefore, reducing material dust is of great significance for cost reduction, efficiency improvement, and minimizing environmental and human health hazards.
[0004] In existing technologies, although dry powder materials such as fuel, quicklime, limestone and dolomite can fall into the mixed powder, the belt vibration during the production process inevitably causes secondary dust. In addition, there is a certain distance between the dust cover and the conveyor belt, and the site is not tightly sealed, which easily causes the dry powder to fly and scatter, resulting in waste of raw materials and environmental pollution. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a dust collection device and its conveyor belt suitable for dust recycling.
[0006] According to the present invention, a dust collection device suitable for dust recycling is provided, comprising a first baffle and a second baffle;
[0007] The first baffle and the second baffle are respectively arranged on both sides of the belt and are both located above the belt. The distance between the tail of the first baffle and the second baffle is greater than the distance between the head. The upper parts of the first baffle and the second baffle are both mounted on dust covers. The lower parts of the first baffle and the second baffle are respectively provided with a first flexible stop and a second flexible stop. The lower parts of the first flexible stop and the second flexible stop are in contact with the belt.
[0008] Preferably, both the first flexible stop and the second flexible stop are made of rubber sheets.
[0009] Preferably, the first flexible stop and the second flexible stop are detachably mounted on the first baffle and the second baffle, respectively.
[0010] Preferably, the first flexible stop and the second flexible stop are respectively mounted on the first baffle and the second baffle by bolts.
[0011] Preferably, both the first baffle and the second baffle are made of iron plates.
[0012] Preferably, both the first baffle and the second baffle are bolted to the dust cover or welded to the dust cover.
[0013] Preferably, the height of the first flexible stop is higher than the distance between the lower end of the first baffle and the belt, and the height of the second flexible stop is higher than the distance between the lower end of the second baffle and the belt.
[0014] Preferably, the first baffle is provided with a first elongated oval through hole extending along the height direction, and the second baffle is provided with a second elongated oval through hole extending along the height direction. The first flexible baffle and the second flexible baffle are respectively provided with a first circular through hole and a second circular through hole matching the first elongated oval through hole and the second elongated oval through hole.

[0016] The conveyor belt provided by this utility model includes the aforementioned dust collection device.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This invention designs a first baffle and a second baffle on the belt, with flexible baffles configured at the lower part of each baffle. The lower part of the flexible baffles contacts the belt, filling the gap between the dust cover and the belt. This creates a more enclosed material conveying space composed of the dust cover, belt, and flexible baffles, resulting in better sealing. Dust is less likely to fall outside the belt, and any dust that is blown or scattered due to belt vibration or other reasons is more easily sucked away by the duct. This saves raw materials, is environmentally friendly, has a simple structure, low cost, is easy to implement, and has good versatility. Attached Figure Description

[0043] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0044] This utility model provides a dust collection device suitable for dust recovery, such as... Figure 1 , Figure 3 , Figure 4 As shown, it includes a first baffle 1 and a second baffle 2. The first baffle 1 and the second baffle 2 are respectively arranged on both sides of the belt 31 and are both located above the belt 31. The distance between the tail ends of the first baffle 1 and the second baffle 2 is greater than the distance between the heads, so that the conveying space gradually narrows in the material conveying direction, and it has a figure-eight shape when viewed from above. Figure 2 As shown, this reduces the suction space between the dust cover 8 and the belt 31, making the dust more concentrated and inhibiting the spread of dust to a certain extent. This helps the fan to suck the dust away from the suction space and improves the suction efficiency.
[0045] Furthermore, the upper parts of the first baffle 1 and the second baffle 2 are both installed on the lower part of the dust cover 8. The upper part of the dust cover 8 is connected to the air duct 81. The lower parts of the first baffle 1 and the second baffle 2 are respectively equipped with a first flexible baffle 4 and a second flexible baffle 5. The lower parts of the first flexible baffle 4 and the second flexible baffle 5 are in contact with the belt 31. The height of the first flexible baffle 4 is preferably higher than the distance between the lower end of the first baffle 1 and the belt 31, and the height of the second flexible baffle 5 is preferably higher than the distance between the lower end of the second baffle 2 and the belt 31. The design of the first flexible baffle 4 and the second flexible baffle 5 fills the gap between the dust cover 8 and the belt 31, so that the dust cover 8, the belt 31, the first flexible baffle 4, and the second flexible baffle 5 form a more relatively closed material conveying space with better sealing. Dust is not easy to fall to the outside of the belt 31, and the floating and scattered powder is more easily sucked away by the air duct 81, which saves raw materials and is also beneficial to environmental protection.
[0046] In practical applications, both the first flexible stop 4 and the second flexible stop 5 can be made of flexible plates such as rubber sheets. For example, PVC rubber sheets can be used, or waste belts can be used to make flexible stops. Specifically, flexible stops can be made from scrap materials, which is low in cost and easy to manufacture.
[0047] When fixed, the first flexible stop 4 and the second flexible stop 5 are detachably installed on the first baffle 1 and the second baffle 2, respectively. Since both the first flexible stop 4 and the second flexible stop 5 are in contact with the material and their bottoms rub against the belt 31, they are easily damaged. Therefore, they are designed as detachable structures, allowing for easy replacement if the first flexible stop 4 or the second flexible stop 5 is damaged. For example, the first flexible stop 4 and the second flexible stop 5 can be detachably installed on the first baffle 1 and the second baffle 2, respectively, using bolts.
[0048] Furthermore, the belt 31 contacts and rubs against the bottom of the flexible stop during rotation, causing the flexible stop to wear down and shorten easily. To extend its service life, in one possible embodiment, the first stop 1 is provided with a first elongated oval through hole 11 extending along the height direction, and the second stop 2 is provided with a second elongated oval through hole 21 extending along the height direction. Figure 5 As shown, the first flexible stop 4 and the second flexible stop 5 are respectively equipped with a first circular through hole 41 and a second circular through hole 51 that match the first oblong through hole 11 and the second oblong through hole 21. The first flexible stop 4 can be assembled onto the first baffle 1, and the second flexible stop 5 can be assembled onto the second baffle 2 using a connector, preferably a bolt. Initially, the flexible stop can be installed at the top of the oblong through hole. As the bottom of the flexible stop wears, it can be gradually installed towards the lower part of the oblong through hole to ensure that the bottom of the flexible stop is always in contact with the belt 31. Through the design of the oblong through hole, after the bottom of the flexible stop wears, the bolt can be loosened, the flexible stop moved downwards a certain distance, and then fixed back in place. At this point, the bottom of the flexible stop can again be in sealed contact with the belt 31. The structure is simple and the operation is convenient. In another possible embodiment, as... Figure 6 As shown, it also includes a first limiting plate 6 and a second limiting plate 7. The first flexible stop 4 is arranged between the first limiting plate 6 and the first stop 1, and the second flexible stop 5 is arranged between the second limiting plate 7 and the second stop 2. By setting the limiting plate, the problem of the nut on the bolt being not securely fixed can be avoided, making the flexible stop more securely fixed. The limiting plate can be made of rectangular iron plate or made by directly drilling holes in strip steel, which is convenient and quick to manufacture.
[0049] Specifically, the first baffle 1 and the second baffle 2 are preferably made of iron plates. The first baffle 1 and the second baffle 2 can be fixed in various ways. For example, they can be bolted to the dust cover 8 or welded to the dust cover 8 for a more secure fixation.
[0050] This utility model also provides a conveyor belt, the conveyor belt 3 including a support 33, idlers 32 arranged on the support 33 and a belt 31 arranged on the idlers 32. The belt 31 is equipped with a dust collection device, which makes the top of the belt better sealed, and it is not easy to cause dry powder to fly and scatter, thereby reducing raw material waste and environmental pollution.
[0051] Practical testing has shown that the closing device in this invention can lift up the mixed powder with high moisture content on both sides and cover the dry powder material in the middle, solving the problem of secondary dust generation and thus reducing raw material loss and environmental pollution.
[0052] This invention can be made from locally sourced materials, such as waste belt baffles and strips, resulting in low cost, simple installation, and strong portability. It requires no special tools or auxiliary equipment and is suitable for use on sintering batching belt conveyors under different working conditions, demonstrating good versatility.
