Description

Technical Field

[0001] This utility model relates to the field of fly ash feeding technology, specifically a fly ash warehouse feeding device. Background Technology

[0002] Fly ash is a fine particulate waste collected from the flue gas after the combustion of pulverized coal in thermal equipment such as coal-fired power plants, and it belongs to an important category of industrial solid waste. It is mostly gray or grayish-white powder, with fine particles and a light texture. Its main chemical components are silicon dioxide, aluminum oxide, iron oxide, and a small amount of calcium oxide, similar in composition to clay. In the past, fly ash often occupied land due to its stockpiling, and it was prone to dust generation in the wind and water seepage, posing a significant environmental problem for enterprises. However, with technological advancements, it has now become an important resource recycling material, widely used in concrete admixtures to improve the workability and strength of concrete. It can also be used in the production of wall materials, roadbed fillers, and soil conditioners, realizing the transformation of waste into treasure. It plays a vital role in reducing costs and resource consumption in the construction and infrastructure sectors.

[0003] Due to the physical characteristics of fly ash (fine powder, easily absorbs moisture and clumps), traditional warehouse hoppers are mostly single inverted conical or square pyramidal structures, with the cross-sectional area of ​​the discharge opening decreasing sharply from top to bottom. During the descent, fly ash is prone to bridging (particles compressing each other to form a stable arched structure) and wall adhesion (adhering to the hopper wall after absorbing moisture), leading to channel blockage. Furthermore, traditional devices mostly rely on gravity-fed discharge, lacking crushing, mixing, or agitation mechanisms. Once "arching" occurs, manual clearing by tapping the hopper wall and inserting steel pipes is required, affecting efficiency. Utility Model Content

At the same time, the stainless steel scraper can scrape off the fly ash on the inner wall of the hyperbolic transition hopper with a gradient flow channel, and the crushing plate can break up the clumps of fly ash, which can also achieve the effect of stirring.

[0005] To achieve the above objectives, a fly ash silo unloading device is provided, comprising a base, a fixed frame fixedly connected to the upper surface of the base, a gradient flow hyperbolic transition hopper fixedly connected to the upper side surface of the fixed frame, a feed pipe fixedly connected to the upper surface of the gradient flow hyperbolic transition hopper, the feed pipe communicating with the interior of the gradient flow hyperbolic transition hopper, a second motor fixedly connected to the upper surface of the gradient flow hyperbolic transition hopper at its center, the output end of the second motor passing through the upper surface of the gradient flow hyperbolic transition hopper and a connecting block fixedly connected to its lower end, stainless steel scrapers fixedly connected to both ends of the connecting block, a rotating shaft fixedly connected to the lower surface of the connecting block, and a crushing plate fixedly connected to the outer surface of the rotating shaft.
