Granular food crop long-distance screw type pneumatic transportation system

Abstract

A granular food crop long-distance screw type pneumatic transportation system comprises a material transportation main pipeline, connecting material suction devices, gas-solid two-phase flow forming devices, a mechanical screw flow swirling device, pneumatic screw flow enhancing devices, a flow distributing device, gas-solid separation devices, storage warehouses and an automatic control and monitoring system. According to the granular food crop long-distance screw type pneumatic transportation system, efficient and low-energy-consumption gas-solid two-phase flow long-distance transportation of food crops is achieved through pipeline screw flow with a coupling enhancement effect; the food crops are directly transported to the destination warehouses through a sealed pipeline, and thus indirect losses caused by waterway transportation, railway transportation or land transportation are reduced; and meanwhile, an intermediate transit link is omitted, a lot of freight is reduced, oil resource consumption and exhaust gas emission are reduced, and environment-friendly long-distance pipeline transportation is truly achieved.

Description

technical field [0001] The invention belongs to the technical field of pneumatic conveying of rice husks and crop grains, in particular to a long-distance spiral pneumatic conveying system for granular grain crops. Background technique [0002] my country is a big producer and consumer of grain crops. From the place of origin to the processing enterprises or storage warehouses, the logistics methods such as water transport, land transport or railway transport are currently used. During the process of loading, unloading, and transportation, broken bags and bulk Losses such as leakage and spilling waste a lot of materials, manpower and energy, and pollute the environment at the same time. [0003] At present, although some mechanical equipment is used for the loading and unloading of crop seeds, it still requires a lot of manpower, and the labor intensity is high, the scope of application is small, dust and noise are generated, and the working environment is poor.

[0002] my country is a big producer and consumer of grain crops. From the place of origin to the processing enterprises or storage warehouses, the logistics methods such as water transport, land transport or railway transport are currently used. During the process of loading, unloading, and transportation, broken bags and bulk Losses such as leakage and spilling waste a lot of materials, manpower and energy, and at the same time cause pollution to the environment

[0003] At present, although some mechanical equipment is used for the loading and unloading of crop grains, it still requires a lot of manpower, and the labor intensity is high, the scope of application is small, dust and noise are generated, and the working environment is poor.

[0004] Pneumatic conveying or airflow conveying is a technology that fluidizes crop particles and uses the energy of airflow to transport along the direction of airflow in a closed pipeline, but both negative pressure suction and positive pressure pressure are only used for Short-distance transportation, the longest transportation distance generally does not exceed 1000 meters, which limits the scope of use
