Abstract
A microvacuum storage apparatus for agricultural and subsidiary products is composed of air extractor, air bag, container, and packing cases of agricultural and subsidiary products. The internal space of said air bag is communicated with ambient atmosphere. When air is extracted out, the air bag can be automatically expanded to fill the space in container to decrease the pressure suffered by wall of container. It can prevent the dewatering of agricultural and subsidiary products.
Description
Affiliated technical field
The utility model relates to a kind of agricultural byproducts storage facilities, no matter especially can make its volume size of common container all can reach the effect of common subatmospheric pressure storage.
Background technology
At present, known subatmospheric pressure storage facility is made up of container, air extractor, pressure control device etc.After the agricultural byproducts that are stored are placed container, make container airtight, start air extractor gas in the container is extracted out, the content of keeping oxygen is about 3%, and this moment, container inner pressure was about 1/10 barometric pressure, was equivalent to the pressure 0.9kg/cm on the leakproof tank outer wall
2Pressure increases with the face area of container, and the wall of container of example one side 2m * 2m is under pressure then up to 360 tons.Bear huge pressure like this and do not destroy, or it is thick to strengthen wall of a container, or add support at internal tank.Not only make the container of making very heavy, increased cost, brought very big difficulty also for the storage of agricultural byproducts in the container and management.This is that breadboard " bottleneck " place appears being difficult in decades walk out in the subatmospheric pressure storage technology always.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing subatmospheric pressure storage facility, the utility model provides a kind of micro-vacuum storage facilities, this facility can not only reach the effect of common subatmospheric pressure storage simply, and can greatly reduce the carrying and the deadweight of container, and manufacturing cost also reduces significantly.
The technical scheme that its technical matters that solves the utility model adopts is: place some air bags in container, air bag communicates with external environment after passing wall of container by a joint.When the Turnover Box that holds agricultural byproducts in container, stack finish after, leakproof tank.Start air extractor, in the container to outside inflation automatically in air bag when beginning to bleed, the free space outside the Turnover Box reduces gradually until disappearance, the absolute mass of oxygen reduces rapidly in the container.Afterwards, be interrupted and start air extractor and make and maintain a less vacuum ranges in the container, on the one hand the portion gas in the Turnover Box space is drawn out of, further reduce oxygen content to keep the required low-oxygen environment of agricultural byproducts normal physiological activity, on the other hand agricultural byproducts are breathed outside the pernicious gas amount discharge containers such as ethene that produce.Most of amount of air in the agricultural byproducts space reduces by flexibility inflation bead or bag.
The beneficial effects of the utility model are, micro-vacuum can be realized the effect of subatmospheric pressure storage effect, the automatic inflation of air bag has reduced the outer wall pressure (for below 1/10 of common subatmospheric pressure storage) of container significantly, and the consumption of power of its deadweight, air extractor is significantly reduced; Flexible bead has played the effect of falling oxygen and packing, can suppress the dehydration of agricultural byproducts preferably.Easy to use, cost is low, large-scale promotion application simply.
Accompanying drawing 1 is the elevation profile constructional drawing of micro-vacuum storage facilities.
Accompanying drawing 2 is A-A sectional structural maps of accompanying drawing 1.
Accompanying drawing 3 is B-B sectional structural maps of accompanying drawing 2.
Accompanying drawing 4 is to utilize flexible inflation bead to eliminate the scheme drawing in space between agricultural byproducts
1. air bags in the accompanying drawing 1,2. container, 3. air extractor, 4. Turnover Box, 5. joint
1. oxygenating hole, 2. trays in the accompanying drawing 2
The specific embodiment
In accompanying drawing 1, air bag (1), pass container (2) by a joint (5) and communicate with extraneous environmental gas.The aspirate tube of air extractor (3) inserts in the Turnover Box (4).
Turnover Box (4) when vanning, simultaneously the inflation bead of the flexibility shown in agricultural byproducts and the accompanying drawing 4 or bag (diameter varies in size with the individual oad of far products and different, or the ball of different-diameter is mixed put) are put into, to discharge the most of amount of air in its space.The aspirate tube place of air extractor (3) establishes protecting wire net (mesh is less than little ball diameter), in order to avoid suck in the pump housing.
In accompanying drawing 2, can cooperate by manual or self-con-tained unit and establish the fresh air that oxygen analyser needs via oxygenating hole (1) additional agricultural byproducts repository in the Turnover Box.
Claims (3)
1. agricultural byproducts micro-vacuum storage facilities, Turnover Box of being used by air extractor, air bag, container, far products splendid attire etc. constitutes.Oneself constitutes a closed system to it is characterized in that container, and the air bag in the container communicates with container environmental gas outward after passing wall of container by a joint.
2. micro-vacuum storage facilities according to claim 1, when it is characterized in that air extractor is bled, the outer gas of container enters air bag automatically, by the gas in the inflation eliminating container, the absolute mass of oxygen is reduced.
3. micro-vacuum storage facilities according to claim 1, it is characterized in that the interstitial oxygen of agricultural byproducts by load in mixture flexible inflatable ball or the bag reduce.
