Flat plate base type accelerated discharge device and steel plate bin thereof

Abstract

The invention relates to a flat plate base type accelerated discharge device and a steel plate bin of the device. The steel plate bin comprises a bin body of a cylindrical body, a bin top and a blockcrushing assembly. The bin top is arranged on the top of the bin body, a flat plate bin bottom is fixed to the bottom of the bin body and provided with multiple discharge pipes distributed at equal intervals, the tops of the discharge pipes are provided with multiple feeding holes which communicate with the interior of the discharge pipes and distributed at equal intervals, the flat plate bin bottom is provided with multiple guide cones distributed at equal intervals, a pressure reducing cone is fixed to the portion, between every two adjacent guide cones, of the flat plate bin bottom, the pressure reducing cones are located over the feeding holes, and the block crushing assembly is arranged inside the bin body. Block materials can be squeezed and crushed, it is ensured that materials in the bin body smoothly flow into the feeding holes, an auxiliary discharge pipe is arranged to separate materials in the discharge pipes, and the material discharge speed is improved.

Description

technical field [0001] The invention relates to the technical field of steel silos, in particular to a plate-based accelerated discharge device and a steel silo. Background technique [0002] The steel silo is mainly used to store cement, fly ash, slag powder, clinker, grain and granular materials. As the country attaches great importance to the field of energy conservation and environmental protection, steel plate warehouses have a wide range of markets and broad application prospects. [0003] At present, most of the discharge systems of floor-standing powder (cement, fly ash, etc.) steel silos adopt the form of underground single-corridor single-hole or multi-corridor porous discharge, and high-pressure air is used to boost the powdery materials out of the steel silo. However, due to the long-term storage of the material, it is easy to get wet and agglomerate, thereby blocking the feed hole under the decompression cone, so that the material cannot be discharged from the ...

Problems solved by technology

[0003] At present, most of the discharge systems of floor-standing powder (cement, fly ash, etc.) steel silos adopt the form of underground single-corridor single-hole or multi-corridor porous discharge, and high-pressure air is used to boost the powdery materials out of the steel silo. However, due to the long-term storage of the material, it is easy to get wet and agglomerate, thereby blocking the feed hole under the decompression cone, so that the material cannot be discharged from the discharge pipe, and the system uses the pressure of the material in the steel plate warehouse to keep the pipe in a closed state. The compressed air can blow the material. When there is less material in one of the outlets, the high-pressure air will emerge from the inlet and lose the boosting ability, resulting in more powder materials remaining in the bin.
