Description

technical field [0001] The invention relates to a pneumatic conveying device, in particular to an electrolytic manganese dioxide dense-phase pneumatic conveying device. Background technique [0002] The electrolytic manganese dioxide product needs to be blended with different batches of products after going through processes such as stripping, crushing, washing and drying. At the same time, it is necessary to transfer the powder between different silos. Pneumatic conveying is usually used to transport granular materials along the airflow direction in a closed pipeline, which is a specific application of fluidization technology. The traditional conveying method adopts dilute-phase conveying technology, which is divided into suction-type dilute-phase conveying and pressure-feeding dilute-phase conveying. Dilute-phase conveying technology has a solid content of less than 100kg / m3 and a solid-gas ratio of less than 25. The conveying air velocity is high (about 15-30m / s), the m...

AI Technical Summary

Problems solved by technology

The conveying air velocity is high (about 15-30m / s), the material damage and equipment wear are relatively large, and the energy consumption is high

Dilute phase conveying is not suitable for conveying from unloading station to silo or from silo to silo, nor for conveying between electrolyzer silos

With the continuous development of productivity, enterprises have further requirements for the reduction of production energy consumption and the improvement of product quality, and the production efficiency of dilute phase transportation can no longer meet the actual needs

The control system of the traditional dilute-phase conveying device is controlled by a single-chip microcomputer, the operation is more complicated, the system function is relatively simple, the man-machine interface is not intuitive, the operator is inconvenient to use, and the equipment maintenance personnel cannot modify the program according to the change of the process; at the same time, the single-chip microcomputer control of the system System stability is not high
