Description

Technical Field

[0001] This utility model relates to the field of dust removal system technology, and in particular to an automatic dust removal system for large-scale zinc concentrate conveying environments. Background Technology

[0002] In the zinc smelting industry, zinc concentrate is an important raw material, and environmental control during its transportation is crucial. Taking the roasting raw material conveyor belt corridor area of ​​the zinc plant as an example, this area undertakes the large-scale transportation of zinc concentrate. However, due to the fine particle size and high sand content of the transported raw material, a large amount of dust inevitably falls during long-term transportation, resulting in a thick layer of dust accumulating on the ground, railings, walkways, and platforms.

[0003] Currently, the main methods for cleaning accumulated dust in this area are manual sweeping and negative duct assisted blowing. However, these two methods have significant limitations: firstly, manual sweeping is extremely labor-intensive, requiring substantial manpower and time, and workers are frequently exposed to dust during the process, facing occupational health risks such as dust inhalation, resulting in poor work safety; secondly, negative duct assisted blowing can only clean relatively loose surface dust, failing to completely remove the large amounts of dust already adhering to walls and cable trays, leading to recurring dust accumulation and a consistently poor indoor working environment, which not only affects production efficiency but also poses a potential threat to the normal operation and lifespan of equipment. Therefore, this utility model proposes an automatic dust removal system for large-scale zinc concentrate conveying environments. Utility Model Content

[0004] The purpose of this utility model is to address the problem in the background technology that the raw material conveyor belt area of ​​the zinc plant is difficult to clean due to the fine particle size and large amount of loose sand in the large-scale transportation of zinc concentrate. The existing manual sweeping and negative duct assisted cleaning methods have problems such as large workload, safety, incomplete cleaning, poor working environment and impact on equipment operation. The present invention proposes an automatic dust removal system for the large-scale transportation of zinc concentrate.

[0005] The technical solution of this utility model is as follows: An automatic dust removal system for large-scale zinc concentrate conveying environments, comprising a Roots blower, with a bag filter connected to the output end of the Roots blower and a duct connected to the input end of the Roots blower; multiple sets of dust collection components connected to the duct, each dust collection component including multiple sets of connecting pipes connected to the duct, a shut-off valve installed at one end of each connecting pipe, and a flexible hose connected to the end of the shut-off valve away from the connecting pipe; and a collection mechanism disposed on the side of the dust collection components for holding the flexible hose.

[0006] Optionally, the side of the duct is provided with multiple sets of I-beams, and each set of I-beams is fixedly connected to a mounting frame on both sides. The mounting frame is L-shaped, and the duct is mounted on top of the multiple sets of mounting frames.

[0007] Optionally, the collecting mechanism includes a rotating shaft rotatably connected to one side of the I-beam, and a hanging rod is fixedly connected to the rotating shaft, the hanging rod being L-shaped.

[0008] Optionally, a support rod is rotatably connected to the bottom of the hanging rod, and a movable rod is rotatably connected to the end of the support rod away from the hanging rod. Multiple sets of limiting blocks are slidably connected to both sides of the movable rod, and the multiple sets of limiting blocks are fixedly connected to the I-beam.

[0009] Optionally, a rotating rod is rotatably connected to the top of the moving rod, a sliding sleeve is slidably connected to the rotating rod, and positioning rods are fixedly connected to both sides of the sliding sleeve. The positioning rods are rotatably connected to the I-beam, and two sets of positioning plates are provided on the inner side of the I-beam to fit against it. The two sets of positioning plates are respectively fixedly connected to the two sets of positioning rods.

[0010] Optionally, a fixing ring is provided on the side of the sliding sleeve near the moving rod, the fixing ring is fixedly connected to the outer ring of the rotating rod, and a spring is provided between the sliding sleeve and the fixing ring, the spring being sleeved and installed on the outer ring of the rotating rod.

[0011] Optionally, a limiting ring is fixedly connected to the outer ring of the rotating rod, and the limiting ring is positioned on the side of the sliding sleeve away from the fixed ring.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention uses a Roots blower to generate negative pressure to drive a dust-collecting component, which can quickly adsorb dust and small particulate materials scattered in the belt conveyor area. After being filtered by a bag filter, the dust is separated from the air, which not only effectively purifies the working environment, but also allows the adsorbed materials to be reused through backwashing, reducing resource waste.

[0014] The hose of the further dust suction component can be wound and stored by the hanging rod of the collection mechanism. With the help of rotating rods, springs and other structures, the angle of the hanging rod can be flexibly adjusted, which not only makes it easy for workers to quickly pick up and put down the hose for cleaning operations, but also allows the hose to be stored on the side of the I-beam, avoiding occupying the space of the conveyor belt corridor and improving the cleanliness of the site and the safety of operation.

[0015] In summary, this utility model can achieve efficient and automatic cleaning of accumulated dust, reduce manual labor intensity and occupational health risks, improve the working environment and ensure stable equipment operation. Attached Figure Description

[0030] Example

[0031] like Figure 1 and Figure 2 As shown, this utility model proposes an automatic dust removal system for large-scale zinc concentrate conveying environments. It includes a Roots blower 1, with a bag filter 2 connected to the output end of the Roots blower 1 and a duct 3 connected to the input end. The Roots blower 1 transports small particles and dust scattered in the conveyor belt area to the bag filter 2 for filtration via the duct 3. The bag filter 2 can reuse the adsorbed material through backwashing. Both the Roots blower 1 and the bag filter 2 are existing technologies and will not be described in detail here. Multiple sets of I-beams 31 are installed on the side of the duct 3, and the positions of the I-beams 31 are fixed. Mounting frames 32 are fixedly connected to both sides of the multiple sets of I-beams 31. The mounting frames 32 are L-shaped, and the duct 3 is mounted above the multiple sets of mounting frames 32, ensuring stable installation of the duct 3.

[0032] Furthermore, the aforementioned dust removal system includes multiple sets of dust suction components 5 connected to the duct 3. Each dust suction component 5 includes multiple sets of connecting pipes 51 connected to the duct 3. A shut-off valve 52 is installed at one end of each connecting pipe 51, and a flexible hose 53 is connected to the end of the shut-off valve 52 away from the connecting pipe 51. After the shut-off valve 52 is opened, the negative pressure generated by the start of the Roots blower 1 causes the end of the flexible hose 53 away from the shut-off valve 52 to generate suction, which facilitates the suction of dust and raw materials scattered in the belt conveyor area into the duct 3.

[0033] For further details, please refer to Figures 3 to 5The dust removal system also includes a collection mechanism 4 located on the side of the dust collection component 5. The collection mechanism 4 is used to hold the hose 53. The collection mechanism 4 includes a rotating shaft 41 rotatably connected to one side of the I-beam 31. A hanging rod 42 is fixedly connected to the rotating shaft 41. The hanging rod 42 is rotatably connected to the side of the I-beam 31 via the rotating shaft 41. The hanging rod 42 is L-shaped, which facilitates the winding of the hose 53 onto the hanging rod 42 for storage, avoiding occupying too much space in the conveyor belt corridor. A support rod 43 is rotatably connected to the bottom of the hanging rod 42. A moving rod 44 is rotatably connected to the end of the support rod 43 away from the hanging rod 42. When the moving rod 44 moves, it causes the hanging rod 42 to deflect through the support rod 43, and the support rod 43 supports the hanging rod 42. Multiple sets of limiting blocks 45 are slidably connected to both sides of the moving rod 44. The multiple sets of limiting blocks 45 are fixedly connected to the I-beam 31. The fixed position of the limiting blocks 45 makes the movement of the moving rod 44 smooth. A rotating rod 46 is rotatably connected to the top of the moving rod 44. When the rotating rod 46 deflects, it drives the moving rod 44 to move. A sliding sleeve 47 is slidably connected to the rotating rod 46. Positioning rods 48 are fixedly connected to both sides of the sliding sleeve 47. The positioning rods 48 are rotatably connected to the I-beam 31. Two sets of positioning plates 49 are provided on the inner side of the I-beam 31 and fit against it. The two sets of positioning plates 49 are fixedly connected to the two sets of positioning rods 48 respectively. The positioning rods 48 and positioning plates 49 keep the sliding sleeve 47 in its original position and rotate. A fixing ring 410 is provided on the side of the sliding sleeve 47 near the moving rod 44. The fixing ring 410 is fixedly connected to the outer ring of the rotating rod 46. A spring 411 is provided between the sliding sleeve 47 and the fixing ring 410. The spring 411 is sleeved and installed on the outer ring of the rotating rod 46. When the rotating rod 46 deflects, it slides in the sliding sleeve 47. At the same time, the fixing ring 410 moves synchronously and compresses the spring 411. The elastic force of the spring 411 limits the position of the moving rod 44. A limiting ring 412 is fixedly connected to the outer ring of the rotating rod 46. The limiting ring 412 is set on the side of the sliding sleeve 47 away from the fixed ring 410 and fits against it. The setting of the limiting ring 412 limits the deflection angle of the rotating rod 46.

[0034] In this embodiment, after the Roots blower 1 starts, it blows gas toward the bag filter 2, and the gas flows at high speed in the duct 3. When it is necessary to clean the dust in the conveyor belt corridor, the operator lifts the rotating rod 46 upward. When the rotating rod 46 deflects, it drives the moving rod 44 to move downward under the limiting action of the limiting block 45. At the same time as the moving rod 44 moves downward, the rotating rod 46 slides in the sliding sleeve 47. At this time, the fixing ring 410 approaches the sliding sleeve 47 and squeezes the spring 411. When the rotating rod 46 deflects through the horizontal state, the spring 411 releases its elastic force, causing the moving rod 44 to move to the lowest position. When the moving rod 44 moves downward, it drives the hanging rod 42 to tilt through the support rod 43, making it easier to remove the hose 53 from the hanging rod 42. The shut-off valve 52 is opened. Due to the high-speed flow of gas in the duct 3, the end of the hose 53 away from the shut-off valve 52 generates suction. The operator holds the hose 53 to absorb the dust in the conveyor belt corridor. Dust is blown into the bag filter 2 by the Roots blower 1 for layer-by-layer filtration, and finally the air is blown out from the top of the bag filter 2. Multiple dust suction components 5 clean different parts of the belt conveyor. After cleaning, the shut-off valve 52 is closed, and then the rotating rod 46 is pulled down to reset it, and the hanging rod 42 is turned into a horizontal position, which makes it easy to wrap the hose 53 around the hanging rod 42.

[0035] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
