Description

Technical Field

[0001] The utility model relates to the field of engineering equipment, in particular to a large silo with enhanced broken arches. Background Art

[0002] As concrete mixing plants become larger, the storage bins for aggregates and sands they are equipped with are also getting larger, sometimes even accommodating 800-1000m 3 Materials, although large-capacity silos can store more materials at one time, due to the size limitation of the discharge port, the silos are generally made into a structure with a large top and a small bottom. The materials are easy to aggregate or arch in the silo, especially the sand with high humidity is more likely to arch in the lower part of the silo, affecting the smoothness of unloading. In severe cases, it is even blocked in the silo and cannot be unloaded. Although most large-capacity silos are currently equipped with vibration arch-breaking devices, some materials with high humidity or viscosity are more likely to compact after vibration. In addition, since the silos are large and mostly built with concrete, it is difficult to resonate, and the arch-breaking effect is still not ideal. Sometimes manual assistance is required to clean the arch, affecting the work efficiency. In view of this, it is necessary to improve large silos. If large silos can be made into silos that combine concrete and steel wall panels that are easy to resonate, and can be combined with a variety of different arch-breaking methods to enhance the arch-breaking effect, the fluidity of the material and the work efficiency can be improved. This is a problem to be solved in this case. Utility Model Content

The inclined wall plates 21 of the two groups of silo bottom inclined wall assemblies 2 are symmetrically placed on both sides of the square holes arranged in a line on the bottom wall of the silo body 1 to form a collection trough with a top spacing greater than the bottom spacing. The inclined wall plates 21 of each group of the silo bottom inclined wall assembly 2 are composed of a number of steel plates of equal size. In this embodiment, a wear-resistant lining is laid on the working surface of the steel plate. The vibration arch breaking group 22 of each group of the silo bottom inclined wall assembly 2 includes a plurality of electromagnetic vibrators, which are an even number of pieces, and the plurality of electromagnetic vibrators of each group are evenly divided and arranged in two rows, and the two rows of electromagnetic vibrators are respectively arranged at the upper and middle parts of the inclined wall plate 21 of each group of silo bottom inclined wall assembly 2, and at least one electromagnetic vibrator is respectively arranged at the upper and lower parts of each steel plate of the inclined wall plate 21. In this embodiment, an electromagnetic vibrator is respectively arranged at the upper and lower parts of each steel plate of the inclined wall plate 21, and the electromagnetic vibrator is locked on the back of the inclined wall plate 21. The electromagnetic vibrator is a well-known technology, and the high-frequency vibration generated by it during operation can effectively eliminate the blockage and arching phenomenon caused by internal friction, deliquescence and component segregation of the material, and the steel inclined wall plate 21 can generate resonance under the action of the electromagnetic vibrator to utilize arch breaking.
