Abstract
The invention provides an automatic discharge device for powder in ton packaging bags and a discharge method. The automatic discharge device for the powder in the ton packaging bags comprises a preparation unit, a receiving unit, a material suction unit, a discharge unit and a control unit. A rotating holding arm mechanism of the preparation unit corresponds to rotating hoppers of the receiving unit. The rotating hoppers of the receiving unit correspond to suction heads of the material suction unit. The suction heads in the material suction unit communicate with a discharger in the discharge unit through pipelines and valves. The suction heads of the material suction unit communicate with air. A vacuum pump of the discharge unit communicates with air through a pipeline. The control unit is connected with the other units. The method for conducting discharge through the device mentioned above includes the steps of preparation, receiving, material suction and discharge. The device and the method solve the discharge problem of the powder in the ton packaging bags and particularly aim at the problems that in the process of discharging aluminum oxide in ton packaging bags in an electrolysis plant, dust escapes outwards, pollution is severe, the labor productivity is low and the packaging bags cannot be repeatedly used, and the economic benefits of enterprises are improved.
Description
technical field [0001] The invention belongs to the technical field of powder engineering, and in particular relates to an automatic unloading device and method for ton-bag powder. Background technique [0002] With the implementation of the country's western development strategy, the production capacity of electrolytic aluminum with high energy consumption in the central and eastern regions has been transferred to the western region. According to statistics, in 2015, the output of electrolytic aluminum in Xinjiang and Inner Mongolia was 8.461 million tons, which requires about Alumina was 16.9 million tons, most of which were shipped to the above-mentioned regions in tons of packaging. [0003] The existing method for the tons of alumina shipped to the electrolytic aluminum manufacturers in the above-mentioned areas is to cut the packaging bag and pour the alumina into the hopper to be transported to the electrolysis workshop. This unloading method has been labeled "barbari...
