Heavy type intelligent environmental-friendly grain moving and purifying system

Abstract

The invention discloses a heavy type intelligent environmental-friendly grain moving and purifying system. The impurities in the grain materials are separated through a screening device, then the grain materials are concentrated through a winnowing device, and the output grain after being cleaned reaches a national standard. Negative-pressure gathering points are arranged at the positions at which impurities and dust leak at the feeding positions and discharging positions of a dedusting device, the screening device and the winnowing device. Multilevel gathering and recycling on impurities and dust are conducted through the dedusting device, a separating device and a tail gas purifying device, and the emitted tail gas reaches an emission standard of national environmental protection. The functions of large processing quantity processing and protecting environment are achieved. Dust pollution in field operation environment is controlled effectively, and the effects of controlling the occurring frequency of professional pneumoconiosis is achieved. The product performance is improved greatly, and the development of industry technology is accelerated. The market share of the product is facilitated, the added value of the product is increased at the same time, and both the economic benefit and the social benefit of an enterprise are improved.

Description

Technical field: [0001] The product involved in the invention is applied to the technical field of cleaning large-scale grains into warehouses, improving the environmental protection of fine impurities and dust, and preventing operators from occupational pneumoconiosis. Background technique: [0002] According to statistics: In 2012, China's grain output reached 589.57 million tons; the per capita annual grain possession was about 400 kilograms, the world's total grain output was 2.28 billion tons, and the world's total population was about 7.09 billion people; the world's per capita grain possession was 321.7 kg. As the saying goes, "Food is paramount to the people." China feeds 22% of the world's population with 7% of the world's arable land. There are 18,326 grain storage enterprises across the country, with a total warehouse capacity of 392.556 million tons, a simple warehouse capacity of 34.216 million tons, a shed of 15.087 million square meters, and a floor area of ​...
