Description

Technical Field

[0001] This invention relates to the field of blast furnace ironmaking technology, specifically to an automatic dust suppression device for conveyor belts transporting various materials. Background Technology

[0002] During blast furnace ironmaking, a large amount of gas ash is carried out along with the raw gas from the furnace top. This gas ash is captured and intercepted by gravity dust collectors and dry dust collectors, and then transported to gas ash silos for storage and reuse via suction and discharge tank trucks. It is then mixed with raw coal and processed through a series of grinding and drying processes to produce pulverized coal that can be injected into the blast furnace. The gas ash and raw coal in the gas ash silos and raw coal silos are mixed and transported to the raw coal silo via control valves and chutes onto a conveyor belt. The particle size of the gas ash is typically less than 10mm, with a common range of 0–5mm; the particle size of the raw coal is generally between 10–80mm. During the transportation of gas ash and raw coal, due to the small particle size and light weight of the gas ash, dust is easily generated, causing resource waste and environmental pollution.

[0003] The use of belt conveyors to transport materials of varying particle sizes is common in blast furnace ironmaking processes. Therefore, dust collection systems are typically installed within the belt conveyor corridors. Direct dust collection without any measures would lead to wasted energy, high equipment investment, and material loss. Thus, it is necessary to improve and innovate the belt conveyor system to adapt to the technological advancements and environmental protection needs of my country's steel industry.

A connecting plate 408 is rotatably connected to the top of the limiting slide rod 407 via a rotating shaft. One end of the connecting plate 408 is rotatably connected to one side of the feeder 404 via a rotating connecting rod 409.

[0052] Please see Figure 1The guide plate 501 has a guide groove on one side, and one side of the guide plate 501 is smooth. The back of the guide plate 501 is inlaid with wear-resistant rubber. Unlike other dust suppression devices that introduce new media, such as spray dust removal and negative pressure dust collection, this invention is based entirely on the material characteristics for self-dust suppression. It can achieve good dust suppression effect without additional power consumption. The feeder 308 and feeder 404 have a simple structure, low investment, low maintenance cost, and small equipment body that is not limited by space. When the material flow changes, the feeder 308 and feeder 404 can adjust the opening angle and height to achieve self-dust suppression of different material flow rates. The device is highly flexible and can significantly reduce powder dust while reducing powder loss and resource waste. This device has universality of raw materials and is suitable for most scenarios where a single conveyor belt transports materials of various particle sizes. The feeder 308 and feeder 404 can be made of wear-resistant materials such as ceramic and manganese steel to reduce friction with the material contact surface. A 2-3cm rounded edge is reserved at the bottom close to the conveyor belt to prevent scratching the conveyor belt.

[0053] Working principle: During use, the drive motor 203 is controlled to work, which drives the power roller 202 to rotate, thereby cooperating with the belt 204 to rotate. When the position of the distributor 308 needs to be adjusted, the screw ring 310 is loosened, so that the screw ring 310 releases the pressure on the slider 304. Then the sliding rod 305 and the horizontal plate 306 on the slider 304 move. When the height of the distributor 308 needs to be adjusted, the screw 307 is rotated, and the screw 307 drives the distributor 308 to move up or down.

[0054] When the position of the feeder 404 needs to be adjusted, loosen the nut 412, and then move the moving rod 401 on the moving block 400, thereby moving the position of the feeder 404. When the angle of the feeder 404 needs to be adjusted, rotate the threaded rod 410. The threaded rod 410 drives the limiting slide rod 407 on the sliding plate 406 to move, thereby causing the rotating connecting rod 409 on the side of the connecting plate 408 and the feeder 404 to rotate, thus adjusting its angle.

[0055] Block materials (greater than 10mm) fall onto the conveyor belt assembly 2 through the block material (greater than 10mm) feeding structure 302. When the conveyor belt assembly 2 transports the block materials (greater than 10mm) through the distributor 308, the distributor 308 separates the block materials (greater than 10mm) into concave shapes in the middle.

[0056] When the conveyor belt assembly 2 transports the block material (greater than 10mm) with a concave center to the powder material (less than 10mm) feeding structure 303, the powder falls into the concave part of the block material (greater than 10mm). When the conveyor belt assembly 2 transports the block material (greater than 10mm) and the powder material (less than 10mm) to the collector 404, the collector 404 closes the block material (greater than 10mm) that was divided by the distributor 308 on both sides of the conveyor belt assembly 2 so that it covers the powder material (less than 10mm) and prevents the powder material (less than 10mm) from floating on the surface and generating dust.
