Description

Silo discharge device

Technical field

The present invention relates to a silo discharge device for storing loose materials.

Background technique

The lower part of the existing silo is generally contracted, and a discharge port or a discharge passage is provided on the reduced bottom surface to provide a funnel-like gathering effect, but in practical applications, it is found that the piled material is formed at the slope of the contracted bottom. The arch, which is completely dependent on the shrinking bottom structure at the bottom of the silo, is difficult to export from the discharge opening. To this end, a silo has been proposed, such as the utility model patent of the publication number 202897570U. In this patent, the bottom of the silo has a tapered shape to form more than one longitudinal discharge passage, and a stirrup is longitudinally disposed at the bottom of the discharge passage. When the material falls along the cone to the bottom of the silo, the material falling into the bottom of the silo is used to output the stock by the forced propulsive force of the auger. The inventors have experimentally proved that the silo still cannot completely solve the arching of the material on the bottom cone surface, and it is very easy to be on the bottom cone surface for the material with poor fluidity, especially when the biomass material is easy to adhere to each other. Arching affects its normal discharge.

In order to solve the above problems, the utility model of the publication No. 202203972U proposes a discharge device for a flat bottom bin, which has two processes of blanking and discharging. A plurality of screw propulsion devices, such as augers, are arranged at the bottom of the silo, and the material falling into the bottom of the silo is disturbed by the screw thrust of the screw propeller, and the material is further pushed into the discharging device located below the silo. Then, the material is output outside the bin by the discharging device. However, the discharge device of the above structure has the following inevitable drawbacks:

First, the above-mentioned screw propulsion device is driven by a driving device located outside the bin, but since the propeller device pushes the material only slightly larger than the diameter thereof, only when the screw propeller device needs to be arranged closely, can it fall into The materials at the bottom of the silo are all exported. This high-density arrangement should not have the same density of openings in the wall of the bin, which greatly affects the strength of the bin. Therefore, the structure is only suitable for a silo with a small volume and a low strength requirement, and its application range has great limitations.

Secondly, in the above structure, although the arrangement is dense, some materials remain between the two propellers, and the residual materials cannot be discharged for a long time, and form a serious arch under continuous pressing. And forming an extremely rough arching surface between the auger devices, the auger device between them has to carry out the material's propulsion and derivation movement in the passage formed by the rough arching surface, making it easier to enter the screw propulsion device or the material in between Arching, thereby increasing the propulsion motion resistance of the screw propulsion device, wasting energy consumption, and affecting the discharge effect of the silo.
