Abstract

The utility model discloses a CO2 grain storage device, which solves the defects in the existing grain depot or barn. The CO2 grain storage device comprises a top cover, an outer wall of the grain depot, an injection port, a lock entrance and a pipeline network, etc., wherein, the injection port is arranged at the top end of the outer wall surface of the grain depot. The top cover is covered above the injection port. A sealing element is arranged between the lower end of the top cover and the outer wall surface of the grain depot. The pipeline network is arranged on the bottom plane in the grain depot and is connected with a CO2 storage tank through a flowmeter. The lock entrance is arranged on the outer wall surface of the grain depot. The CO2 grain storage device discharges air from the grain storage device by making use of the different specific gravities of air and CO2, so as to lead the grain in the CO2 gas to be in a dormancy state, thus reaching the goals of fresh and quality keeping, no mildewing, anti insect pest, so as to improve the quality of the grains that are stored, reduce the grain loss as well as the cost of grain storage.

Description

The carbon dioxide grain storage apparatus

One, technical field

The device that the utility model belongs to keeping, stores grain particularly relates to the device that a kind of employing carbon dioxide (being CO2) gas stores grain.

Two, background technology

The keeping of grain, storage, the most frequently used also is that the most original storage method is to be stored at after grain is dried in bucket, jar, the silo, especially silo or grain depot (being grain storage apparatus), its structure is actually a storehouse, and general grain passes in and out from a door, considers ventilation, thereby on the storehouse wall, be provided with vent window, be provided with ventilating duct between the grain buttress, and take measures such as insect protected, protection against rodents, fire prevention, cost is many.This grain storage apparatus seems simply, easily goes, and also is present among the people and national silo method commonly used.But the problem that exists is many: at first be that the grain of depositing must dry, that makes moist is not all right, in case infiltrated wet grain, just made the rising of grain temperature and, cause so-called grain " to get damp " with the steam generation, moisture makes grain and the aggravation of mould vital movement again, cause grain to go mouldy, turn to be yellow, lose hugely, will often detect the grain temperature in the silo for this reason, in case heating will ted, need a large amount of human and material resources resources of cost; Next is must throw in pesticide and rodent poison bait for insect protected, protection against rodents, pollutes; Three, can not deposit for the grain that does not dry, but China region is wide, and plum rains are run in the south of the lower reaches of the Yangtze River wheat, rapeseed harvesting often, and often The autumn rain fall day after day without ceasing during rice harvesting, the grain that causes gathering in turns to be yellow, goes mouldy because of can not in time drying warehouse-in, loses huge.Though cold preserving method keeping seed is arranged at present, and low temperature can make seed be in deep sleep state and never degenerate, this method is all right to preserving endangered species, and for the depositing of a large amount of grains, its expense can't be born.Also have the warm grain depot of so-called ice, can make grain fresh keeping, but its cost is very high, can not store as commercial.Must improve design to existing grain storage apparatus (being grain depot, silo etc.), and to take new preservation grain method be the content of food administration department research always for this reason.

Three, utility model content

The purpose of this utility model is that a kind of novel grain storage apparatus will be provided, to overcome the existing many defectives of traditional grain storage apparatus.This novel grain storage apparatus---carbon dioxide grain storage apparatus (abbreviating CO2 silo or CO2 grain depot as) can adopt following technical scheme to implement: it is by top cover, the grain depot exterior wall, inlet, sluice gate and grid are formed, wherein inlet is located at the top of grain depot wall face, top cover covers above inlet and with grain depot wall face upper end and is connected and fixed by the top cover fixture, between the lower end of top cover and grain depot wall face, be provided with seal, grid is contained on the outer baseplane within the walls of grain depot and by flowmeter and connects with the CO2 air accumulator, sluice gate is located on the grain depot wall face, generally be located on the grain depot wall face near the grid top, on the pipe of grid, be provided with the CO2 venthole.

Silo that the carbon dioxide grain storage apparatus of forming according to said structure and existing grain storage are used or grain depot are compared has following advantage: the grain in 1, the good seal performance, grain storage apparatus is moisture-sensitive not; 2, store certain density CO2 by the venthole on CO2 air accumulator and the grid in the grain storage apparatus, make the interior grain of device be in resting state, can not go mouldy, thus do not need often to ted, and can keep original nutritional labeling of grain; But 3, insect protected under certain density CO2 gas condition in the grain storage apparatus, protection against rodents, fire prevention; 4, owing to grain storage under the CO2 gas condition, also can improve the capacity utilization of grain depot, the grain storage cost declines to a great extent.

Four, description of drawings

Fig. 2, grid structural representation.

Five, the specific embodiment

Below in conjunction with accompanying drawing, the carbon dioxide grain storage apparatus is further described.

As shown in Figure 1 and Figure 2, the carbon dioxide grain storage apparatus is made up of top cover 3, grain depot exterior wall 7, inlet 4, sluice gate 9 and grid 8, wherein inlet 4 is located at the top of grain depot wall face, top cover 3 covers above inlet 4 and with grain depot wall face upper end and is connected and fixed by top cover fixture 5, between the lower end of top cover 3 and grain depot wall face, be provided with seal 6, grid 8 is contained on the outer baseplane within the walls of grain depot and by flowmeter 2 and connects with CO2 air accumulator 1, sluice gate 9 is located on the grain depot wall face, is provided with the CO2 venthole on the pipe of grid.

During the carbon dioxide grain storage apparatus work of building up according to said structure, at first open top cover 3, grain injects grain storage apparatus from inlet 4, loading finishes bonnet upper top cover 3, and be connected and fixed by top cover fixture 5 and grain depot wall face, open CO2 air accumulator 1, pass through flowmeter 2 to the grid gas transmission, and CO2 is injected in the grain depot by the venthole on the pipe on the grid, its air demand is by flowmeter survey and control, original air is discharged outside the storehouse by inlet in the grain depot, after CO2 concentration reaches certain value, close the CO2 air accumulator, carry out grain storage and fresh-keeping.Open sluice gate when putting out cereal, grain takes out from sluice gate.Because air specific weight is lighter than CO2, thus rarefaction of air in the storehouse, grain is in deep sleep state and can go bad, and insect pest, mouse can't generate, and CO2 can put out a fire again, thus the purpose that realizes improving the grain storage quality, reduces the grain storage cost.

Claims

1. carbon dioxide grain storage apparatus of forming by top cover (3), grain depot exterior wall (7), inlet (4), sluice gate (9) and grid (8), it is characterized in that inlet (4) is located at the top of grain depot wall face, top cover (3) covers in the top of inlet (4) and with grain depot wall face upper end and is connected and fixed by top cover fixture (5), between the lower end of top cover (3) and grain depot wall face, be provided with seal (6), grid (8) is contained on the outer baseplane within the walls of grain depot and by flowmeter (2) and connects with CO2 air accumulator (1), and sluice gate (9) is located on the grain depot wall face.
