Description
Technical field：The present invention is the natural heat insulation and heat control thermal-insulating scheme of national large granary, belongs to natural environmental-protective grain storage technology
Field.
Background technology：In order to prepare against war and natural disasters, in order to which people's army has meal, large-scale grain storehouse storage is had in each country
Substantial amounts of grain, but be present problems and need solution in grain storage, such as to dry, low temperature, hypoxemia effectively could protect food to pacify
Entirely, it otherwise can easily go mouldy, damage by worms, the problems such as shortening the grain storage phase.Grain storage science personnel are come up with using in silo at this stage
If ventiduct system, spray foam layer Puttying layer strengthens insulation in surrounding and top surface in storehouse, utilizes winter to be pumped into cold air
Through grain layer reduction grain temperature in storehouse and then seal storehouse and the method such as be incubated, the problem of to solve low-temperature grain-storage；Using filling inert gas
To realize that hypoxemia protects the purpose of grain, the purpose of redrying is reached simultaneously using machinery cooling.But these measures are but brought
New the problem of, that is, winter pumping is put in storage while grain in storehouse can be made to add humidity, that is, add weight, seeming is
Good thing, add yield increases the income of grain depot in fact, but has buried after grain is risen again because high humidity is high and can produce
The risk quickly gone mouldy；Due to silo loading food 2/3rds, the inflation expense of more than half is wasted to silo inflated with nitrogen；Machine
Tool cooling obtains the effect of redrying simultaneously, but capacity can be reduced during export can or can not directly reduce grain depot incomeThis is certain
The problem of being individual reality, what ifThis is subject matter to be solved by this invention.
The content of the invention：In order to overcome above-mentioned problem, using outside storehouse surrounding, day cover reflection and heat insulation layer, in thermal insulation layer again
Bonus point interts some radiating heat pipes every the multiple provision for thermal insulation of thermal insulation layer using in the separation thermal insulation layer being installed in addition with, and stretches out on interlayer board
Heat pipe be epimere, stretch out below interlayer for hypomere, and cover fin in the hypomere of heat pipe, sucking cuboid covered in epimere, heat-insulated
One side window on layer upper strata installs some automatic control air exhausters or water screen type temperature-lowering machine, is opened automatically during using the night day lowest temperature
Dynamic exhausting, cold wind blows heat pipe epimere, and water evaporation refrigeration cools down thermal insulation layer every inner layer space；To keep not heating up in low temperature bin
Or heat up at a slow speed or gradually reduce temperature, reflection and heat insulation layer keeps out sunlight and does not directly shine storehouse face and cause heat transfer, causes silo to inhale
Heat rise temperature produces influence to grain storage, allows silo to cool for refrigerating plant refrigeration using solar panels film electricity source.Second
Step adds one layer of insulated foam coating closing using press seal plastic film layer in silo grain aspect, and in film layer, lazy for reducing filling
Property gas tolerance and keep low temperature do not rise or slowly rise or cool be easier, realize the fresh-keeping more longlasting more economical purpose of desinsection.
3rd step is installed using outside heat pump storehouse, the circulating ventilation pipeline upper and lower opening reserved outside storehouse is connected using conduit airduct, by heat pump
Grain layer in cold air input storehouse, is penetrated through after cooling grain thing from the bottom up or from top to bottom, and reentrying heat pump from exhaust outlet backflow connects
Continuous refrigeration is again in input storehouse, and enter to allow its natural evaporation to be mixed into cold air in air inlet pipe the chilled water re-injection that heat pump is discharged
In return grain layer to keep the humidity of grain constant all the time.Realize machinery cooling economize on electricity and the purpose of the not underproduction.
Specific embodiment：In order to realize the content of the invention, specific embodiment point four, first scheme it is characterized in that：
Installed and be covered with (being used to generate electricity and keep out on the storehouse face of large granary using solar energy power generating plate or solar power generation film
Sunshine directly according to shining on silo face, causes heat transfer to cause the problem of silo heats up), occur using solar panels film
Power supply on the one hand electrical connection to be filled with storage battery group standby, on the other hand electrical connection refrigerating plant refrigeration；The power supply of storage battery group is opened
Pass is electrically connected with the transfer switch of refrigerating plant；Refrigerating plant includes heat pump or semiconductor cooling device, and the device can be filled
In after orlop side or window loaded on silo interlayer outdoors, the cold air outlet connection airway tube of refrigerating plant with silo air inlet
Connection, the gas outlet of silo and the air inlet of refrigerating plant are connected logical with conduit or the gas outlet of refrigerating plant are introduced directly into grain
The heat pipe epimere that storehouse thermal insulation layer is installed is blown over, and the heat energy in storehouse is led automatically using heat pipe and shed, and reaches temperature in reduction silo
Purpose.Alternative plan it is characterized in that：Reflection and heat insulation plate is installed in the top surface of silo, using the reflection action of the device too
Sun can be reflected back to be gone in the air, is prevented solar thermal energy from being conducted to storehouse face using heat-insulated filled board, is utilized the ventilation under reflection and heat insulation plate
Road pacify air exhauster institute it is incoming with radiate into heat energy scatter away with the wind, realize the mesh that silo top surface is transferred to without solar energy in silo
's；Separated two sheaf spaces up and down of the another mezzanine space in silo, i.e. one layer of heat-insulated laminate of the space mounting of the thermal insulation layer of silo, under
Layer accounts for 1/3rd of former space, interts some heat pipes unidirectionally conducted heat in heat-insulated laminate, under half is under heat pipe insertion plate
Section endotherm section, stays in the half of plate face for the jacketed sucking cuboid of epimere and water storage disk and installs water supply preventing water leakage and exhaust cooling system additional
Device, accelerates heat sinking function for expanding hypomere endotherm area and the refrigeration of enhancing epimere water evaporation, realizes and keep silo after cooling
The purpose not heated up.Third program it is characterized in that：Some air exhausters are installed in the side window of silo thermal insulation layer one, it is heat-insulated in silo
Another side window of layer installs aeration-cooling cascade or some of cascade cooler, for the temperature in heat-insulated sheaf space to be dropped
It is low, prevent solar thermal energy and temperature from including heat energy and being heated up again into the silo for having reduced temperature in storehouse by thermal insulation board conduction；For
More insure, in the whole sticking insulation reflector layers in silo periphery, finally realize the mesh that silo keeps low temperature, constant temperature to store grain for a long time
's.Fourth program it is characterized in that：Filling grain and reducing the grain faces of two road film-pressing tanks is encapsulated in the grain aspect of grain layer temperature
