Steel plate bin with coiled stacked discharging device

Abstract

The invention discloses a steel plate bin with a coiled stacked discharging device. The steel plate bin comprises a lower support which is horizontally arranged on a silo bottom foundation of a silo, and an upper support connected with the silo top of the silo. A supporting shaft arranged in the center position of the lower support vertically extends to the center position of the upper support. Stepped conveying plates are spirally arranged on the supporting shaft at intervals from top to bottom. The conveying plates incline downwards from top to bottom in the spiral direction. A baffle is arranged at the outer edge of each conveying plate. The coiled stacked discharging device can effectively decrease the descending speed of materials, so that blocking of materials is avoided; and the structure is simple, no power is needed, low carbon and energy saving are achieved, and the effect is remarkable.

Description

technical field [0001] The invention relates to a steel silo with a spiral stacking and dropping device. Background technique [0002] The feeding principle of the traditional silo is that the material enters the silo from the feed port and falls freely to the bottom of the silo. During this process, the material acquires a great speed and has a great kinetic energy. When the material collides with the bottom of the warehouse, some fragile materials will be damaged, which will change the properties of the material, which is not suitable for some materials that have strict requirements on the properties. [0003] In this regard, Chinese patent application 201310657292.1 discloses a steel silo screw feeding device, which uses a shallow groove-shaped conveying plate for buffering and conveying. Specifically, it includes a lower bracket horizontally arranged on the bottom of the silo and a The upper bracket is horizontally arranged on the roof of the warehouse, the support shaf...
