Description

Novel shell-shaped stock bin structure

Technical Field

The utility model belongs to the technical field of storage equipment technique and specifically relates to a novel shell shape feed bin structure is related to.

The existing bulk cargo strip-shaped stock bin mainly has a three-center circle structure type, as shown in fig. 14, and is characterized in that an integral roof frame is fixed with a foundation through a left hinge shaft and a right hinge shaft. This type of silo, although widely used, has the following problems:

1. the roof frame is fixed with the foundation through a left hinge shaft and a right hinge shaft. Because the roof frame structure has higher rigidity and is sensitive to the foundation deflection, particularly the horizontal deflection, of the left hinge shaft support and the right hinge shaft support, the support foundation generally adopts a pile foundation bearing platform form, and the foundation investment is higher. Especially in the deep soft soil foundation occasion, under the heap of material heap carries pressure effect in the storehouse, the soil body warp can produce outside horizontal thrust and warp to the pile foundation, can cause pile foundation overload and roofing frame construction to transship. In order to control the horizontal displacement of the foundation, the soil body in the front area of the pile foundation needs to be reinforced by gravel piles or sand piles, so that the foundation engineering quantity is further increased, and the investment is greatly increased.

2. Bulk materials have special stacking properties, and the included angle between the inclined plane of the stacked material stack and the horizontal plane is within the range of the stacking angle. In a three-center circular type of bin as shown in figures 14 and 15, the stacker-reclaimer device is generally centrally located with two stacks on the left and right sides. The arrangement causes the large middle upper space of the section surrounded by the expensive stock bin to be just used as the passing space of the high-rise bucket-wheel stacker-reclaimer and cannot be used as the basic function of the stock bin, as shown in fig. 16, the stacking space cannot be fully utilized, and the capacity of the left and right two stacks is much smaller than that of one stack with the same bottom width.

3. The three-center circular structure type storage bin is provided with the belt conveyor and the bucket-wheel stacker-reclaimer in the middle for loading and unloading materials, as shown in fig. 15, so that the storage bin can only select one item in the storage-in operation or the storage-out operation at the same time, the operation flexibility is limited, and the operation efficiency is also influenced.
