Description

Dust suppression hopper

Technical Field

The application belongs to the technical field of environmental protection equipment, and specifically relates to a dust suppression hopper.

Background

At present, in the transportation process of the domestic grain wharf, the bulk grain delivery modes mainly include a loading shed loading mode, a silo self-flow mode and a direct ship-to-vehicle mode. Wherein grain comes out from the blanking mouth at the transportation and moves down with very fast initial velocity, and the whereabouts in-process, material and elephant trunk pipe wall collision produce the dust, and the collision also can produce the dust between the material each other. Under the mutual shearing action of the moving materials and air, the high-speed airflow extruded by the materials carries dust to fly around. Because the fall from the discharge port to the final blanking point is large, a large amount of dust is generated and diffused to the surrounding environment when the blanking impacts the ground. The generated dust belongs to tiny dust, and the particle size of the dust is basically less than 10 um. The mass of dust particles is small, and the settling speed is slow, so that the settling needs to be continued for a period of time, and the smaller particle size is in a floating state for a long time. In addition, the dust is explosive and harmful to the health of operators, and simultaneously pollutes the atmospheric environment.

The existing dust suppression hopper is fixed, and the flow rate cannot be adjusted according to the shape of the material; or adopt the spring pressure formula to come to adjust the opening size according to material gravity, for example a dust suppression fill that CN204846912U disclosed makes the material closely knit the discharge gate at the bucket body, extrudes out the unnecessary air between the material granule to produce the raise dust when avoiding the ejection of compact. The dust suppression hopper has a dust suppression effect, but the hopper body is suspended by the extension springs, the tension of each extension spring is difficult to keep consistent, and the inclination of the hopper is easy to occur to influence the dust suppression effect of discharging; meanwhile, the opening degree of the discharge port is adjusted only by the weight of the materials, so that the use requirements of different types of materials are difficult to meet.

Accordingly, there is a need for an improved dust suppression hopper.
