Energy-saving extra long distance automatic pneumatic transmission system

Abstract

The invention discloses an energy-saving extra long distance automatic pneumatic transmission system which comprises a drying tower (1). The drying tower is characterized in that a gas and material mixing cabin (8) communicates in the drying tower (1), a small cabin (18) communicates in the gas and material mixing cabin (8), an air flow anti-blockage device (21) is arranged at the communicating part of the gas and material mixing cabin (8) and the small cabin (18), a speed-up cabin (23) is arranged in the air flow anti-blockage device (21), an L-shaped pipe (26) is arranged in the speed-up cabin (23), an electric control pressure gauge (25) communicates to the speed-up cabin (23), an electric control voltage regulating valve II (28) communicates to the electric control pressure gauge (25),and a dry air inlet II (30) communicates to the electric control voltage regulating valve II (28). Compared with the prior art, the energy-saving extra long distance automatic pneumatic transmissionsystem is high in degree of automation, avoids the blockage problem, and guarantees the relatively high transmission efficiency of raw materials while lowering the power cost.

[0002] With the improvement of economic level, the development of industrial technology is getting faster and faster. Pneumatic conveying plays an important role in industrial production. Pneumatic conveying uses the energy of airflow to transport granular materials along the direction of airflow in a closed pipeline, which is a fluid state. A specific application of chemical technology, the pneumatic conveying system is mostly a combination of drying towers, gas-material mixing bins, small silos, etc., with simple structure and convenient operation, and can be used for horizontal, vertical or inclined conveying. During the process, physical operations such as heating, cooling, drying and air classification of materials or certain chemical operations can be carried out at the same time. It has the characteristics of large conveying capacity, long conveying distance and high conveying speed. The pneumatic conveying system can also be installed in one place. However, with the growth of the pipeline and the increase of the height difference, the transportation will also increase exponentially. If it exceeds a certain length and height difference, the phenomenon of material blocking will occur. Therefore, it is urgent to solve this problem. improvement
