Multi-powder storage metering equipment

Abstract

The invention relates to multi-powder storage metering equipment. The multi-powder storage metering equipment comprises a metering scale, a single-body double-bin powder tank, a powder recycling tankand a powder elevator, wherein a partition plate is arranged in the single-body double-bin powder tank to divide the interior of the single-body double-bin powder tank into two bins, the two bins areused for accommodating different powder correspondingly, powder beating pipes are connected to the two bins correspondingly, and the lower discharging ends of the two bins are connected to the metering scale through main metering screw conveyors correspondingly; and the lower feeding side of the powder elevator is connected with the lower discharging end of the powder recycling tank and the discharging end of external recycled powder generating equipment, the upper discharging side of the powder elevator is connected to a multi-way valve, a first outlet of the multi-way valve extends to be connected with the metering scale, and a second outlet of the multi-way valve extends to be connected with the powder recycling tank. According to the multi-powder storage metering equipment, the single-body double-bin powder tank is arranged, two different kinds of powder can be accommodated and stored, and the cost required for adding a new powder tank and the powder elevator in the traditional technology is reduced; and meanwhile, when the capacity of the powder needs to be increased, a plurality of upper and lower powder tank structures can be placed beside the single-body double-bin powder tank in parallel by adopting a mode of adding a proper amount of screw conveyors, and the equipment cost is greatly reduced.

Description

Technical field [0001] The invention relates to the field of asphalt mixture preparation, in particular to a multi-powder material storage and metering device. Background technique [0002] At present, there are two powder storage and measurement methods adopted by the asphalt mixing equipment. One is the structure of the upper and lower powder tanks. The recovered powder stored in the lower powder tank is transported into the main building by the powder elevator for measurement, and the upper powder tank stores the mineral powder by Spiral conveying into the main building for measurement; the other is a double powder tank structure, which consists of a powder tank for storing recycled powder and a powder tank for storing mineral powder. The two powder tanks are used to separate the powder through their respective powder elevators. The materials are transported into the main building for measurement. [0003] When the existing asphalt mixing equipment needs to add slaked lime and ...
