Aluminum powder mixing and metering device

Abstract

The invention discloses an aluminum powder mixing and metering device which comprises a mixing system, a metering system, a pipeline system, a metering and feeding control valve, and a metering and discharging control valve. A discharging port of the mixing system is connected with a feeding port of the pipeline system. A pipeline circulating pump is connected on the pipeline system. The pipeline system is provided with an adding and discharging port and a circulating discharging port, wherein the adding and discharging port is connected to a feeding port of the metering system through the metering and feeding control valve, the circulating discharging port is connected to a returning port of the mixing system, and a discharging port of the metering system is connected to a feeding port of an aerated concrete pouring mixer through the metering and discharging control valve. The operating sequence and operating modes of the metering and feeding control valve and the metering and discharging control valve are controlled by an electrical control system of an aerated concrete production line. According to the aluminum powder mixing and metering device, aluminum powder needed for production in one shift can be supplied through one time of mixing, and therefore the operation is convenient; and moreover, aluminum paste can be automatically measured and added so that errors which are possibly caused by manual adding of the aluminum paste are avoided.

Description

technical field [0001] The invention relates to a matching equipment for concrete production, in particular to an aluminum powder mixing and measuring device. Background technique [0002] Air-entrained concrete is a lightweight, porous new building material with the advantages of light weight, good heat preservation, processability and non-combustion. It can be made into blocks, plates and thermal insulation products of different specifications, and is widely used in load-bearing or maintenance filling structures of industrial and civil buildings. . [0003] When producing aerated concrete blocks, the metered slurry, lime, gypsum, and cement are fully mixed evenly within the time specified by the process through the pouring mixer, and at the same time, the mechanical action and the impact force of the slurry flow are used to make the solid material in the solid material. The agglomerates are fully dispersed, and a small amount of auxiliary materials such as air-generating...

Problems solved by technology

This purely manual method of measuring, stirring and adding aluminum powder requires separate operation for each block. It's a waste product, a waste of manpower and material resources

Due to the special properties of aluminum powder and the small amount used each time, it is difficult to guarantee the weighing accuracy. It is difficult to realize automatic measurement and automatic addition in existing methods.
