Description
Technical field
The utility model relates to a kind of granary ventilation device, belongs to agricultural machinery engineering, agro-product processing and storage engineering and grain and oil and to store in a warehouse field of engineering technology.
Background technology
Force ventilation technology is as one of traditional grain storage technology, obtain in modern grain depot and use widely, the grain storage ventilation unit of current application formed primarily of the ventilating duct of ventilation blower and silo ground configuration and the storehouse of filling grain, major function utilizes ventilation blower that extraneous Cryogenic air is piled by grain, reduces the temperature of grain.
The application of grain storage ventilation unit generality is when ambient temperature is lower than cereal temperature, utilize ventilation blower by Cryogenic air from horizontally disposed in the ventilating duct on ground press-in grain heap, air-flow is vertical or pile laterally across grain, again through heat exchange, by the heat of grain or water transport in air, high temperature air is discharged from grain face, be discharged in air by storehouse window, reach the object reducing grain temperature, be commonly called as the up or forced ventilation of air-flow, or ventilation blower is from ventilating duct sucking-off air, Cryogenic air is piled surface by grain and is entered, through heat exchange, high temperature air is got rid of from horizontally disposed in the ventilating duct on ground, be discharged in air, reach the object reducing grain temperature, be commonly called as the descending or ventilation by low pressure of air-flow, these two kinds of methods are referred to as rectilinear method of ventilation.The ventilation unit of this rectilinear ventilation, ventilating duct mainly adopts geosyncline or on the ground cage type formula, horizontally disposed and be arranged on ground, warehouse, air approach ratio is general about 1.5, during actual ventilation, because air approach is larger, there is dead corner, lower the temperature uneven, the problems such as cooling rate is slow.For solving the problem, increase ventilation blindly, or design parameter and equipment configuration unreasonable cause again ventilating consume energy greatly, the grain moisture content afterwards that ventilates loses seriously, add grain storage cost, time serious, affect stored grain quality.Adopt the draft type of cage on the ground in addition, 3 meter of 1 pipe, during turnover grain, will constantly tear cage mounted cage open, have a strong impact on the mechanical work of turnover grain.
In transversal ventilation system, enter from one end blowing of level pipe, from the other end, wind is extracted out, see in theory and seemingly can reach good ventilation effect, and actual grain is irregular arrangement, therefore do not reach the object of designing requirement and science guarantor grain.
Because the source, storehouse of China is limited, general silo at least will pile the grain of more than 6 meters, and granary ventilation device of the prior art is good to the grain heap effectiveness comparison of less than 4 meters, and the grain of more than 4 meters just has dead corner, draw badly, the time easily rots once long.
Summary of the invention
The purpose of this utility model is, overcomes the shortcoming of prior art, solves the problem of silo dead corner, provides a kind of ventilation unit of comprehehsive type.
The technical solution of the utility model is such: a kind of granary ventilation device, comprise and pass airduct, end airduct, described biography airduct is one rectangular tubular, the corner crossing with ground near silo longer one side wall and arranging, end airduct is be arranged on silo ground and two to pass the centerline that airduct parallels, also comprise discharge pipe, described discharge pipe one end face opening also communicates with biography airduct, described discharge pipe tube wall is provided with air outlet, airduct tube wall of the described end also has air outlet, and the blower fan be arranged on outside silo is connected with one end of end airduct with described biography airduct.
As further technical scheme of the present utility model, the height of described discharge pipe is that rice is to rice.
As further technical scheme of the present utility model, also comprise an air exhauster and a pressure fan, described air exhauster and pressure fan are arranged on two windows be positioned on silo diagonal respectively.
The beneficial effects of the utility model are: 1, ground retains the problem that a ventilating duct avoids dead corner.
2, energy-conservation, ton-grain power consumption is low.3, only need airduct at the bottom of installation one due to 22 meters with the silo ground of inner width, turnover storehouse operation is convenient, is conducive to do mechanization operation, greatly reduces labor strength, go up the work of cage when saving operation removably.4, intake path is than little, effectively reduces dead corner.5, require to reduce to warehouse air-tightness, greatly reduce construction cost.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure figure.
Fig. 2 is the A-A cutaway view in Fig. 1.
In figure, pass airduct 1, discharge pipe 2, end airduct 3, blower fan 4.
Embodiment
The technical solution of the utility model is elaborated below in conjunction with accompanying drawing and embodiment.
As depicted in figs. 1 and 2, a kind of granary ventilation device, comprise and pass airduct 1, end airduct 3, described biography airduct 1 is one rectangular tubular, the corner crossing with ground near silo longer one side wall and arranging, end airduct 3 passes for being arranged on silo ground and two centerline that airduct 1 parallels, also comprise discharge pipe 2, described discharge pipe 2 one end face opening also communicates with biography airduct 1, described discharge pipe 2 tube wall is provided with air outlet, airduct 3 tube wall of the described end also has air outlet, and the blower fan 4 be arranged on outside silo is connected with one end of end airduct 3 with described biography airduct 1.
The height of described discharge pipe 2 is 4 meters to 5 meters.
Also comprise an air exhauster and a pressure fan, described air exhauster and pressure fan are arranged on two windows be positioned on silo diagonal respectively.
In addition, at the bottom of the ground of reservation, airduct not necessarily only has one, depending on the longitudinal length of silo, and the longitudinal length of general silo is less than 22 meters only needs airduct at the bottom of middle, and less than 18 meters effects are better.Length is greater than the end airduct that 22 meters will be established more than two.
