Description

Containment equipment that can disrupt bridging phenomena

technical field

The invention relates to an accommodating device, in particular to an accommodating device that can destroy the phenomenon of bridging.

Background technique

Please refer to FIG. 7 , the granules (materials) contained in the accommodating device 90 will form an arch-shaped stacking structure B due to mutual friction, or the granules will stick to each other or be solidified due to mutual extrusion of weight. The arched stacking structure B is then formed, and the granular bodies cannot be discharged from the accommodating device 90 smoothly, which is the so-called bridging phenomenon, which is a problem that the accommodating device is prone to encounter when discharging.

The existing method of destroying the bridging phenomenon is to set a stirring device, such as a stirring rod, in the accommodating cavity of the accommodating device 90. The granules form an arched stacking structure B, thereby destroying the bridging phenomenon.

Another common method of breaking the bridge is to set a vibration device, such as a vibration motor or an air hammer, on the outer side wall of the accommodating device 90 . The side wall of the device is placed so that when the granules begin to form the arched stacking structure B and the bridging phenomenon occurs, the fulcrum formed by the position where the granules are in contact with the inner side wall of the accommodating device 90 is destroyed, so that the granules cannot be formed smoothly. Arched stacking structure B to avoid bridging.

However, regardless of the above-mentioned methods of destroying the bridging phenomenon, the mechanism is used to prevent the accumulation of particles, which has its disadvantages in use. Therefore, the effect of destroying the bridging will be limited in space. If the bridging phenomenon occurs beyond the operating range of the specific stirring device, the stirring device cannot destroy it. In addition, the accommodating equipment 90 that may cause the bridging phenomenon covers a wide range. Although the stirring device may be used in the storage silo, it is difficult to be installed inside the burner, because the burner penetrates through the burning biomass. The fuel can generate energy, and the ashes can be contained through the furnace base, or further discharged, and when the burner burns, the high temperature will cause the stirring rod to be easily damaged or even burned; another method of vibrating the device will make the containing device 90 pass through After long-term vibration, it is easy to cause fatigue failure or local structural wear.

To sum up, the existing technologies and methods for destroying bridges have limitations that they can only be used with specific containment equipment, or may damage the contents contained in the containment equipment and the containment equipment itself. Improvements.
