Description

Energy saving systems and methods of grain storage and grain processing plants}

The present invention relates to an energy saving system and a method of a grain storage facility and a grain processing facility, and in detail, a transfer facility for transferring various grains (product rice, dry rice, seeds, barley, wheat, soybeans, corn, etc.), grain A sensor is installed in the process facility that processes and processes the product, the dust collection facility that collects dust, and the pneumatic facility, but when the target grain is not detected or the delay time is exceeded (delayed), the facility and/or related facilities are stopped. It is to be saved and the service life is not reduced.

In the conventional milling method, rice harvested with combines, binders, sickles, etc. is packaged and transported to a drying facility, followed by drying, and dried rice is packaged through a process such as pickling and weighing, and then transported to a place of purchase and then packaged. Quality inspection is carried out in the state, and it is stored in warehouses for each grade, stored for a certain period of time, and temporarily stored in the warehouse of the milling factory through processes such as release, loading and unloading, and transported to the milling facility for processing. The RPC: Rice Processing Complex (Rice Processing Complex, Rice Processing System) handles the entire process of rice processing from importing of harvested rice to sorting, weighing, quality inspection, drying, storage, and polishing, to product shipment and sales, and by-product treatment. It refers to a facility that collectively processes a large-scale automated process rather than an individual farm unit, and contributes to the reduction of rural labor force, reduction of rice loss, cost reduction, quality improvement, and distribution structure.

In addition, the rice processing plant is aimed at expanding the purchase function of rice during the harvest season, producing and supplying high-quality local specialty rice, and nurturing it as a center for the distribution of rice in the production area.It also has the purpose of installing it. There is an effect of function supplementation. In the meantime, rice is batch-processed through the rice processing plant, reducing drying and transportation costs by about 34%, promoting brand rice, and absorbing a significant portion of the quantity shipped during the harvest season while the government purchase quantity is decreasing. Although contributing, various facilities, such as process facilities, transfer facilities, dust collection facilities, and pneumatic facilities, are often driven under no load.

for example. It is operated by the operator collectively and operated until the operator stops it even in the no-load state (no load state is the state in which the facility is operated without performing the process), and the grain transfer facility between processes continues until the operator stops it. In addition to being driven, electric energy is wasted without necessity because it is often driven continuously even in a no-load state.

In addition, even though there is no dust generation, the dust collection facility continues to operate until the operator stops it. In other words, even in a situation in which dust is not generated in the process facilities where grain (raw material) is not input and the transfer facility where raw materials are not transferred, the dust collection facility continues to operate until the operator stops it artificially.

When the dust collection facility is operated, energy is wasted by pulsing high-pressure compressed air at regular intervals without taking into account the situation where dust is attached to the filter for dust collection, and the life of the dust collection filter (bag filter, etc.) There were several problems, such as this being shortened.

The production management lot includes production lot (production volume produced within a period), production lot (production volume produced by order), and work lot (production volume continuously working once), and processing, transportation, inspection, and congestion (停滯) ·Purchase ·Storage ·Payment, etc. There are lots. Lot production has no continuity, so it is distinct from continuous production performed by flow operations.

In addition, the transfer equipment (transfer conveyor) may be a belt conveyor, a chain conveyor, a screw conveyor, a bucket conveyor, an air transfer conveyor, a pump transfer conveyor, etc. that are appropriately applied according to the layout of the material to be transferred and the device. .

In addition, since the dust collection facility generates dust only when the process facility and the transfer facility are operated, the dust collection fans 803, 813, 903, and 914 are interlocked only at this time, and the dust collection filters 801, 811, 901, Cleaning of the 912 is performed with the compressed air of the air compressor 920 in the state that the air pulsing valves 804, 814, 904, and 915 are open, and the dust collection filters 801, 811, 901, and 912 are predetermined.
