Abstract
The close grain storehouse of the welded type that the utility model provides is welded by steel panel to form the seal vertical silo had at the bottom of the upper vertex of a cone and lower cone, it is outer that vertical silo is provided with insulation, vertical silo is provided with air pipeline system, the composition of air pipeline system comprises vacuum line, with be arranged in vertical silo under bore ventilation efferent at the end, with around being arranged at the bottom of lower cone the outer total air channel of annular communicated with ventilation efferent, and air source pipelines.The technical program has good heat insulation, damp proof insulation, suppression grain storage is breathed, prevent returning water, suppress infested, the technical performance such as mildew, thus reaches the technical purpose of long-term high-quality grain storage, and its grain storage safeguards that manpower and cost significantly reduce.
Description
Technical field
The utility model relates to granary, in particular large-scale grain storehouse granary.
Background technology
Grain reserves safety, especially large storage level, the safety of storing up grain for a long time are of paramount importance for country or a certain area.In the reserving chamber of existing large-scale Bulk Grain grain storehouse, steel concrete silo is from heat insulation, other storehouse type is compared with the performance such as firm slightly better though prevent fires, but heat-proof quality has sizable limitation, to cause in storehouse particularly top layer because temperature difference condensation most moisture-sensitive, in addition, existing silo is without airtight capabilities, draught capacity is also poor, localized heat is caused to be assembled, moisture increases, occur infested, Signs of Mould, both employing had been made to fumigate, ventilation waits bookkeeping means, but grain storage shelf lives is short, the practical problems such as a large amount of degradation levels of grain storage still cannot be avoided, and concrete operations also can bring sizable potential safety hazard to operating personnel, also grain storage can be made to there is stifling toxic residue, for avoiding the generation of above-mentioned condition, need maintenance management and the input of a large amount of manpower and financial resources, but final grain storage effect is also unsatisfactory.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of welded type close grain storehouse, and it can make warehousing space long term maintenance in airtight anoxia state, and grain storage ventilating is simple, easy, has the technological merit that grain storage quality is high, the stored grain safety phase is long.The close grain storehouse technical scheme of the welded type that the utility model provides, its main technical content is: the close grain storehouse of a kind of welded type, welded by steel panel and form the seal vertical silo had at the bottom of the upper vertex of a cone and lower cone, the center grain-entering mouth of the upper vertex of a cone is provided with seal valve, Xia Zhuidi center grain outlet is provided with sealing door, it is outer that vertical silo is provided with insulation, vertical silo is provided with air pipeline system, the composition of air pipeline system comprises vacuum line, with be arranged in vertical silo under bore ventilation efferent at the end, with around being arranged at the bottom of lower cone the outer total air channel of annular communicated with ventilation efferent, and air source pipelines, vacuum line communicates with the upper vertex of a cone, ventilation efferent is some ridge shape air channels that homogeneous radiation is arranged in around grain outlet, air channel has been evenly arranged ventilation gap to ridge shape.
The close grain storehouse technical scheme of welded type disclosed in the utility model, its vertical silo space is sealing closed grain storage space, the vacuum anoxicity that vacuum pump makes vertical silo space reach suitable through vacuum line, can also ventilate to forming with other and coordinate, vacuum pumping same enter, in storehouse, nitrogen and carbon dioxide is filled into by air source pipelines, make grain in storehouse be sealed in anoxic and maintain in the nitrogen of suitable concentration and carbon dioxide environment to store, for grain storage temperature in adjustment storehouse, utilize north of china in winter cold air aeration-cooling, south is by paddy drying device ventilating and cooling, grain is suppressed to mildew, infested generation, realize long-term high grain storage quality.The technical program has good heat insulation, damp proof insulation, suppression grain storage is breathed, prevent returning water, suppress infested, the technical performance such as mildew, thus reaches the technical purpose of long-term high-quality grain storage, and required grain storage safeguards that manpower and cost consumption also significantly reduce.
Accompanying drawing explanation
Fig. 1 is total structural texture figure of the present utility model.
Fig. 2 is the plan structure figure at the bottom of lower cone.
Detailed description of the invention
The close grain storehouse of welded type disclosed in the utility model forms the vertical silo 1 with at the bottom of the upper vertex of a cone 2 and lower cone 3 by steel panel seal welding, the center grain-entering mouth 4 of the upper vertex of a cone 2 is provided with seal valve, at the bottom of lower cone, the center grain outlet 5 of 3 is by gas-tight silo door termination, form the vertical silo 1 grain storage space that sealing is airtight, it is outer that vertical silo 1 is provided with insulation.The grain storage radius of this grain storehouse can reach 8 meters, whole height can reach the large-scale grain storage silo of about 24 meters.The composition of air pipeline system comprises vacuum line, to be arranged at the bottom of lower cone the ventilation efferent in 3, and the total air channel 8 of the annular being arranged at 3 outer walls at the bottom of lower cone, also comprise air source pipelines 9, vacuum pump 7 is connected to the upper vertex of a cone 2 by vacuum line 6, and pass into vertical silo 1 space, pipeline is provided with control valve; The total air channel 8 of annular communicates with air source pipelines 9; Described ventilation efferent is some ridge shape air channels 10 that homogeneous radiation is arranged in around grain outlet 5, each ridge shape air channel 10 communicates with the intersection in the total air channel 8 of annular, ridge shape air channel 10 arc of 3 inwalls at the bottom of lower cone arches upward on tube wall and is evenly distributed with some ventilation gaps 11, the air intake of air source pipelines 9, comprise temperature adjustment cold wind or make grain be in nitrogen or the carbon dioxide of good anaerobic state, enter each ridge shape air channel 10 by the total air channel of annular 8, spill into vertical silo 1 space through ventilation gap 11.The minimum grain size that the width of described ventilation gap 11 is no more than grain storage particle is wide, enters in air pipeline system to stop grain.At the bottom of lower cone, the ridge shape air channel 10 of inwall is designed, and can ensure the uniformly dispersing of air intake at vertical silo space upper and lower, left and right, ventilate be evenly distributed, ventilation effect is good, and its structure design can not deliver from godown to grain storage gravity flow and forms any obstacle.In this enforcement structure, for ensureing that grain storage, especially paddy rice can be delivered from godown in smooth and easy gravity flow, at the bottom of lower cone, the cone generatrices of 3 is preferably set for 42 ° with the angle of cone baseplane.
