Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of dust suppression equipment in concrete production, and in particular to a dust suppression device for conveying concrete aggregates. Background Technology
[0002] Concrete aggregates refer to granular, loose materials that act as a skeleton or filler in concrete. Currently, for public and environmental reasons, concrete production is typically completed at batching plants, and then distributed to various construction sites via concrete mixer trucks. When producing concrete, a batching plant needs to transport concrete aggregates to a mixer, which mixes the aggregates with other materials to form the desired concrete.
[0003] Concrete aggregates are typically transported using belt conveyors. Specifically, a mixing plant usually has one horizontal conveyor line and one inclined conveyor line. The horizontal conveyor line is used to receive concrete materials, such as aggregates, while the inclined conveyor line is used to transport these materials into the mixing equipment.
[0004] Generally, different material storage hoppers are set above the conveyor line. When the storage hoppers discharge materials onto the conveyor line and when materials are transferred between different conveyor lines, dust will be raised, making the working environment harsh and affecting the health of the workers.

[0026] In an exemplary implementation, such as Figures 1-7As shown, this embodiment provides a concrete aggregate conveying dust suppression device, including a frame 100, a conveyor belt 200, a shield 300, a leveling component 400, a turning component 500, and a spray pipe 600. The shield 300 is sleeved on the top outer side of the conveyor belt 200 and fixedly connected to the top of the frame 100. The leveling component 400 is installed inside the shield 300 and is used to level the material on the conveyor belt 200. The turning components 500 are installed in groups inside the shield 300 and abut against the top of the conveyor belt 200. The turning components 500 are located on one side of the leveling component 400 and are used to turn the material. The spray pipe 600 is embedded in the top inner wall of the shield 300 and is used to spray water mist onto the conveyor belt 200.
[0027] In this embodiment, a shielding cover 300 is provided on the top of the frame 100 to initially block material dust. Then, a spray pipe 600 is provided on the top of the shielding cover 300 to spray water into the interior of the shielding cover 300, thereby suppressing dust.
[0028] Furthermore, a leveling component 400 and a material-turning component 500 are installed inside the shielding cover 300. The leveling component 400 levels the material on the conveyor belt 200, so that the material can be evenly distributed on the conveyor belt 200. Then, the material-turning component 500 turns the material over, so that the material at the bottom can also come into contact with the spray, ensuring that no dust will occur when materials are transferred between different conveyor lines.
[0029] In one embodiment, please refer to Figure 2 The lower half of the inner walls on both sides of the shield 300 are slidably connected to both sides of the conveyor belt 200.
[0030] In this embodiment, the shield 300 abuts against both sides of the conveyor belt 200 but can slide, thereby preventing materials from falling off.
[0031] In one embodiment, please refer to Figures 3-4 The leveling component 400 includes a mounting shaft 410 rotatably mounted between the inner walls of both sides of the shield 300 and a leveling plate 420 sleeved on the outside of the mounting shaft 410. An elastic element 430 is provided between the leveling plate 420 and the shield 300. The elastic element 430 includes two fixing blocks 431 relatively fixedly mounted on the inner walls of both sides of the shield 300 and two curved rods 432 respectively fixedly mounted on the side of the leveling plate 420 near the fixing blocks 431. Each of the two fixing blocks 431 is provided with a sliding hole 433 for penetrating the curved rod 432. A spring 434 is provided between the fixing block 432 and the leveling plate 430 and sleeved on the outside of the curved rod 432.
[0032] In this embodiment, the material moves to one side with the conveyor belt 200 and comes into contact with one side of the push plate 420, pushing the push plate 420 to one side. At this time, the push plate 420 rotates around the mounting shaft 410 as the center, and a certain material flow space is generated between the push plate 420 and the conveyor belt 200. The material that is piled up too high will be flattened by the push plate 420, so that the material is evenly dispersed.
[0033] Furthermore, a spring 434 is provided on one side of the rotating plate 420. The rotation of the plate 420 is compressed by the spring 434 outside the crank 432, which makes the plate 420 adaptable when leveling materials and ensures stability during operation.
[0034] In one embodiment, please refer to Figure 3 and Figure 5 The material turning component 500 includes several scrapers 510 that are slidably connected to the top of the conveyor belt 200 and two sets of material turning blocks 520 disposed on the top of the scrapers 510, with the two sets of material turning blocks 520 being staggered.
[0035] In this embodiment, the scraper 510 can scrape up the material on the conveyor belt 200, and then the material is turned over by the turning block 520, so that the material at the bottom layer is turned over, ensuring the uniformity of material contact with the spray, and the multiple staggered turning blocks 520 can ensure the uniformity of material turning.
[0036] In one embodiment, please refer to Figure 1 , Figure 3 and Figure 6 The top of the shield 300 is provided with a mounting groove 610 for mounting the spray pipe 600. The spray pipe 600 is S-shaped and has several spray nozzles 620 at its bottom.
[0037] In this embodiment, the spray pipe 600 is connected to an external water supply structure at both ends. The dust suppression water is sprayed onto the material through the spray nozzle 620 at the top of the spray pipe 600 to suppress dust.
[0038] Furthermore, setting the spray nozzle 600 to an S-shape ensures a sufficiently wide spray coverage area.
[0039] In one embodiment, please refer to Figure 7 One end of the shielding cover 300 is equipped with a dust-blocking curtain 700, which is installed at the opposite end of the material conveying direction to further prevent dust leakage.
[0040] Finally, please see Figure 1 The top of the shield 300, away from the spray pipe 600, has an inlet 310 and a feed hopper 320.
[0041] To better understand this utility model, the following is combined with... Figures 1 to 7 The technical solution of this utility model is described in detail as follows: In use, a shielding cover 300 is set on the top of the frame 100. The shielding cover 300 initially blocks the dust from the material. Then, a spray pipe 600 is set on the top of the shielding cover 300 to atomize water and spray it into the interior of the shielding cover 300, thereby suppressing dust.
[0042] Furthermore, as the material moves to one side along the conveyor belt 200 and contacts one side of the push plate 420, the push plate 420 is pushed to one side. At this time, the push plate 420 rotates around the mounting shaft 410, creating a certain material flow space between the push plate 420 and the conveyor belt 200. Material that is piled up too high will be flattened by the push plate 420, making the material evenly dispersed. Then, the scraper 510 can scrape up the material on the conveyor belt 200, and then the material is turned over by the turning block 520, so that the material at the bottom layer is turned over, ensuring the uniformity of material contact with the spray and ensuring that no dust occurs when materials are transferred between different conveyor lines.
[0043] In summary, this utility model solves the technical problem of dust generation in existing conveying devices by using a shielding cover 300 in conjunction with a spray pipe 600 to spray materials and a material turning component 500 to ensure full contact between the materials and the spray. This ensures the health of workers and improves environmental protection.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
