Abstract

The utility model relates to a drying granary by wind and electric ventilation, which uses natural wind for grain drying and storing and is a metal granary. The granary is provided with a negative pressure induced draft drying mechanism and a grain elevating transport and agitating mechanism, and a vertical axial flow draft fan 12 is combined with a suction pipe 1 inside the granary to carry out aeration drying. The draft fan is driven by a wind wheel 19 when wind exists. A motor 13 is started to drive the draft fan when wind does not exist. An elevator 8 is arranged in the center of the utility model. Positions of grains in the utility model can be changed often through a toothed spreading reel 11 and a flow guiding pipe machine. The utility model has the advantages of natural drying performance, no pollution for grains, and low cost. Besides, the work of the utility model can save labour and energy.

Description

Drying chamber by wind and electric ventilation

A kind of dryness storehouse that ventilates with wind-force and electric power is the silo that utilizes natural wind to carry out grain drying and storage, can be used on the directly use behind grain harvest of the grain place of production, is applicable to that also grain depot stores grain for a long time, and its international Patent classificating number is F26B11/12.

Various cereal such as grain all have a drying to slough too high moisture processing procedure after results, make within its moisture boundary that drops to safe storage, reach the requirement of safe preservation.Grain is this to dehydrate processing, and except that still carrying out the artificial airing prolonging with the threshing ground, the technology that adopts thermal medium to carry out the batch production drying grows up." the grain processing center " that state farm, Heilongjiang Province system research is in recent years promoted is exactly a kind of modern grain drying factory.In dry factory, the drying technology that adopts is a kind of to be to belong to hyperthermia drying, its heat power supply device is the large-scale dryer of a kind of oil firing, coal or natural gas etc., and what be used to store grain is the metal silo of big capacity, i.e. oven dry and warehousing all carried out respectively by specific installation; Also having a kind of is low temperature drying storehouse baking storage technique, and it combines oven dry and storage, and silo promptly is a dryer, and it still needs heat source furnace that drying medium is provided and provides cold wind with air-cooler.The place of production and grain depot that the high temperature of batch production and low temperature drying technology all are suitable for large-scale grain-production very much use, its oven dry flow scheme design complexity, and plant construction is in large scale, and investment is high, and agricultural production less to scale or idiotype is just very inapplicable.

Research purpose of the present utility model, provide a kind of silo design, it promptly has can store the grain effect for a long time, drying function is arranged again, and its functions/drying needn't be established heat power supply device in addition, be the equipment that the device with a kind of logical natural wind carries out aeration-drying to the grain in the silo, small-scale production can be used, and large-scale production unit also can be used.

The technical characterictic of the dryness storehouse of this logical natural wind is, in the warehouse 14 of dryness storehouse, be provided with exhaust ventilation mechanism and grain stirring mechanism, exhaust ventilation mechanism has the axial id fan 12 of a vertically-arranged to be located at the warehouse top, axial id fan is driven by wind wheel 19 or blower motor 13, when calm weather, can start blower motor and drive air-introduced machine, wind wheel and motor are positioned on the same blower fan axle altogether, there is overrunning cluth the centre, the end opening of blower-casting 18 connects the upper end of each ventilation duct 1, ventilation duct is that umbrella shape is arranged at the warehouse top, each draught tube walls is equipped with air vent, the grain stirring mechanism is to stand in warehouse 14 central authorities to establish an agitator type elevator 8, and there is grain spreading reel 11 on screw feeder vertical shaft top, tiltedly establishes a grain output tube 9 on screw feeder housing top, the tilting grain air deflector 5 that advances a grain tube 6 and a umbrella in bottom, the screw feeder housing that is positioned at umbrella air deflector bottom is provided with the mouth of putting out cereal, and the outside is covered with tubular sliding-sleeve valve 2, and the agitator type elevator passes through belt transmission by motor 15.This dryness storehouse is sharp Lower Hold, and it is installed on the storehouse seat of using brick and cement masonry, and the air intake window is arranged around the seat of storehouse.

Advantage of the present utility model

Guaranteed that the grain quality is not subjected to the pollution of drying medium,, do not had the gas of any burning heating, promptly do not had pollutant to participate in, also do not had the influence of excessive temperature grain quality because the drying medium that this dryness storehouse participates in is a flow air.

Energy savings, drying cost is low because be by wind drive air inducing drying in that wind weather is arranged, only when calm just starter motor drive, so consumes energy is extremely low, reduced the grain drying cost simultaneously.

Applied widely.It is not only applicable to individual agricultural producer on a small scale, adapts to large tracts of land production, production unit that the grain treating capacity is big yet.In addition, this equipment and technology is simple, and cost is low, does not need the job management of manually joining a regular shift or class in the dry run.

Embodiment:

A circle, the point end, capacity are installed is that 300 tons metal dryness storehouse is an example to manufacture, and is described below in conjunction with the accompanying drawings:

The corrugated plating of warehouse 14 usefulness one millimeters thick A3 material is manufactured, and is high 8.8 meters, and 8.16 meters of diameters need 117 of corrugated platings, and (every 2 square metres) are installed with screw thread and connected.Cang Ding is conical, high 1 meter, and its center has the mouth of 0.3 meter of diameter in order to air-introduced machine to be installed, 4 is turbination at the bottom of the storehouse, and height is 1 meter, manufactures with 3 millimeters A3 steel plates, the uniform air inlet that is drilled with 3000 φ 2.5 in bottom surface, storehouse, and leave axis hole that elevator 8 is installed and the window that is used to check cleaning.

Ventilation duct 1 usefulness thin-wall steel tube is manufactured (1.5 inches), totally 56, every hole that is drilled with 1100～1200 φ 2.5 is (because of ventilation duct length difference, hole count can be different), in warehouse, divide 5 circles to arrange 22 of first laps, 16 on second circle, 14 on the 3rd circle, 4 on the 4th circle, each ventilation duct upper end bends compiles seam to the electric fan shell end opening.
