Low-energy-consumption large fluidized powder warehouse and discharge method thereof

Abstract

The invention discloses a low-energy-consumption large fluidized powder warehouse. The low-energy-consumption large fluidized powder warehouse comprises a warehouse body and a warehouse bottom; the warehouse bottom is provided with multiple V-shaped grooves; material conveying pipes are arranged at the bottoms of the V-shaped grooves; material auxiliary flowing devices are arranged on the surfacesof slopes on the two sides of the V-shaped grooves; the material auxiliary flowing devices are specifically pneumatic fluidizing rods; and the material conveying pipes and the material auxiliary flowing devices are connected with an air supply pipeline. The low-energy-consumption large fluidized powder warehouse relates to the field of warehousing equipment, in particular to a large floor fluidization warehouse for storing powder materials. The low-energy-consumption large fluidized powder warehouse overcomes the defects in a traditional large floor fluidization warehouse, and has a series ofadvantages of simple structure, stable discharge flow, simple and feasible taking operation, high material delivery efficiency and the like. A discharge method of the low-energy-consumption large fluidized powder warehouse is simple in operation, stable in discharge flow, high in taking efficiency, excellent in economy, safe, reliable and broad in market application prospect.

Description

technical field [0001] The invention relates to the field of storage equipment, in particular to a large floor-standing fluidized storage for storing powdery materials. Background technique [0002] At present, floor-standing large-scale fluidized storages are mainly divided into two types: concrete silos and steel plate silos. The silo is cylindrical in shape and has the characteristics of large storage capacity and good stability. It is widely used in powders such as cement and fly ash. storage of raw materials. Existing large-scale fluidized storage mainly relies on the discharge port at the bottom of the storage to discharge materials, and the corresponding discharge corridor is set at the bottom of the storage to lead to the outside of the storage to accommodate material conveying equipment and provide maintenance space. In order to ensure the discharge rate of materials, it is usually necessary to set up multiple discharge ports. There is a discharge corridor leading...

AI Technical Summary

Problems solved by technology

However, it has been found in practice that in this type of technology, the fluidization rods are arranged from top to bottom along the slope, and several fluidization rods correspond to the discharge port of a material delivery pipe. When discharging, several fluidization rods need to work at the same time. In order to ensure the normal feeding of the blanking port, due to the large reclaiming area, the discharge flow rate is not stable. When it is smooth, the discharge volume is large and fast, which greatly increases the lifting equipment and subsequent dust collection equipment after the powder is out of the warehouse. The working intensity not only consumes a lot of energy, but even causes blockage in severe cases; when the discharge is not smooth, the discharge volume suddenly decreases, causing air pressure leakage, which not only affects the efficiency of retrieving materials, but also produces energy loss, and the discharge flow rate is not stable. Stability is also easy to cause wear of the material conveying pipe; when there is an abnormality in reclaiming, the reclaiming speed is generally improved by adjusting the air supply pressure of the fluidization rod, but due to the time difference between the adjustment of the air pressure and the change of the reclaiming speed, it is often impossible to adjust in one step In place, it often takes a long time to explore and grasp the changing law between air pressure adjustment and reclaiming speed, which is very inconvenient for reclaiming operators
