Abstract
The invention discloses a flow equalization and transverse penetration type ventilated drying granary which is mainly used for drying and storing corncobs and also can be used for drying and storing food grains. When the granary is used for drying and storing the corncobs, the dried corncobs can be directly obtained without taking the corncobs out of the granary. The granary comprises a granary body, a granary door, a granary cover, a granary bottom, a flow equalizing ventilation pipe, a flow equalizing ventilation pipe base and an axial-flow fan. The granary is characterized in that the specially designed cylindrical ventilation pipe with one end connected with the fan is mounted in the central axis of the cylindrical granary with ventilated periphery; the upper and lower bottoms of the granary are tightly sealed by airtight materials before and after the grains are loaded; air transversely penetrates through the corncobs or the food grains when the fan works, and the ventilation quantity and the drying speed at the periphery, top and bottom of the granary are consistent. The granary has the advantages of uniformity for ventilation, mouse, bird, moisture and mildewing prevention, time, effort and electricity saving, large capacity, good grain quality, convenience for operation and the like; due to the granary, farmers can sell the grains at any time, have the initiative and can obtain maximum economic benefits.
Description
One, technical field:
The present invention relates to grain drying, the mode of storage, method.
Two, technical background:
Current corn main producing region peasant household stores the silo of corn ear and all leans on natural seasoning, and its defect is that only appearance obtains drying, and inside due to can not ventilation can not be dried.Obtain solid food must take grain out of a granary to sun it 1-2 time, waste time and energy.When storage capacity is larger, may takes grain out of a granary to sun it hardly, so most peasant household all selects to sell wet grain, then dried by drying tower.Another tool is looked into newly, though there is people to study the dry silo of forced ventilation, does not solve the problem of silo Uniform Ventilation everywhere, so silo capacity is little, efficiency is low, cost is high.
Three, summary of the invention:
The present invention solves the ventilation of silo inner ventilation and the problem of each position ventilation uniformity under blower fan positive action, take into account on this basis raise the efficiency, reduce costs and rainproof, moistureproof, the protection against rodents of silo, the basic function of anti-bird.
Technical scheme of the present invention: operation principle is: the space between grain seed as airway, can produce blast and make flowing between the space of air between grain seed and taken away by the steam of evaporation, to reach dry object during blower fan work.Key of the present invention is the problem solving storehouse surrounding and lower airway uniformity.Take three concrete measures: one is how to solve silo in same level surrounding Uniform Ventilation for this reason? the measure taked be upper end is connected with blower fan, lower port is shut, the cylinder ventilation duct of surrounding uniform pore openings is arranged on the cental axial position of the cylinder silo of surrounding ventilation.During the work of loading rear fan, because the space, grain equal to silo Edge Distance from pore is consistent, windage is consistent, so just can make silo same level surrounding ventilation unanimously (except near above going to the bottom, because on to go to the bottom neighbouring a large amount of air inlet from top and bottom).Two be before and after loading must with the gas impermeable materials such as Polypropylence Sheet by the bottom of storehouse and grain end face obturage, forbid that air is from bottom surface and end face turnover, and can only lateral penetration silo from the side.This measure is necessary, and it is the necessary condition ensureing the vertical and horizontal direction Even air distribution of silo, otherwise eternal maldistribution of ventilating.Does is three how to solve silo to ventilate in the vertical direction consistent problem? because from blower fan more close to blast larger, wind speed is also larger, and grain drying must be faster.But air quantity can carry out adjustment by increasing ventilation hole area gradually from blower fan near-end to far-end, and can predict to have a kind of state (certain perforated area cardinal sum gradient) that vertical direction ventilation can be made consistent.By many times testing, have now found and can make silo up and down and surrounding ventilation and the consistent state of rate of drying, effect is fine.
The invention has the beneficial effects as follows: each position Uniform Ventilation, silo capacity is large.If for dry, store corn ear, can accomplish to take grain out of a granary to sun it and directly can obtain solid food, and simple to operate, save time, laborsaving, power saving, protection against rodents, anti-bird, protection against the tide, anti-mildew, grain quality is good, and worth peasant household applies.
Four, accompanying drawing explanation
Fig. 1 is that formula ventilation drying granary center section plan is crossed in current-sharing, and silo periphery is full impregnated screen cloth, and ventilation duct surrounding uniform pore openings, perforated area increases gradually from top to bottom.Fig. 2 is ventilation duct base top cross-sectional structure figure (drawing for interval four part).Fig. 3 is ventilation duct base central shaft profile (drawing for interval four part).
In figure at the bottom of (1) warehouse (2) door, (3) Cang Gai, (4) storehouse, (5) flow-equalizing ventilation pipe, (6) ventilation pore, (7) axial flow blower, (8) ventilation duct base, (9) ventilation duct base outer wall, (10) casing wall.
Five, embodiment (silo for stored dry corn ear)
1, warehouse (1) is the cylinder silo be welded with reinforcing bar skeleton.For ease of industrialization production and transport, warehouse adopts the shaping welding of burst, and the used time assembles.For making silo firm, triangle between reinforcing bar, is adopted to connect.For rat preservative, bird pest, framework of steel reinforcement liner screen cloth, lower and cement flooring is touched, and upper and Cang Gai (3) touches.Cang Gai (3) should adopt color steel watt.
2, the high and dry ventilation of physical features should be selected in silo address.For anti-freeze expansion basis should be beaten firmly.For rat preservative silo bottom surface should adopt mattess, generally answer 10 centimetres above ground level.(4) at the bottom of storehouse be in storehouse with flitch or brick pave 5-15 centimetre again boarding in order to protection against the tide.
3, the available plastics cast molding of flow-equalizing ventilation pipe (5) forms, the cental axial position of cylindrical silo should be arranged on, bottom and mattess touch, the suitable installation power in top, the axial flow blower (7) that blast is less, flow is relatively large.Base adopts bushing type: be partitioned into a few part by ventilation duct cross section, then transferred in ventilation duct outer wall vertical section by each aeration portion.
4, for ease of handling grain, should establish multiple door (2) from top to bottom in silo side, loading should use the machine of falling grain, can open door (2) and directly release during unloading.
5, silo must be obturaged at the bottom of storehouse with gas impermeable materials such as Polypropylence Sheets and the end face of grain before and after loading, forbids that air enters from bottom surface and end face, makes it enter from the side.If silo dress is discontented, then the ventilation pore application Polypropylence Sheet exposed or adhesive tape are shut, and do not affect the uniformity that silo ventilates.
6, the diameter of silo is usually at 2-6 rice, and silo height 2-5 rice, ventilation duct diameter 30-120 centimetre, size is determined as the case may be.
7, be rain of swilling anti-rainy season, waterproof cloth can be hung in silo periphery.
8, the present invention is mainly used in stored dry corn ear (fruit ear), secondly also can be used for other grain of stored dry or economic crops seed.
