Abstract
The utility model discloses a fluidized discharge ventilation system for a steel plate silo. The system comprises a steel plate silo body surrounded by a silo top, a silo wall and a silo bottom; a vent hole is formed on the silo top; the silo bottom is of a conical structure with low centre and high periphery; a discharge port is formed on the centre of the silo bottom; an upward-inclined V-shaped launder is uniformly arranged towards the silo wall along the discharge port; an annular air channel communicated with an external air source is arranged on the lower part of the silo body along the silo wall; a branch air channel communicated with the annular air channel is arranged below the V-shaped launder and is communicated with an inner cavity of the silo body through a sieve plate arranged on the bottom part of the V-shaped launder; and an air door is arranged at an air inlet of each branch air channel. The system disclosed by the utility model has the advantages that the basic platform height of the steel plate silo can be effectively lowered by a steel plate silo with relatively large diameter, thus the building expenses are reduced, and a relatively huge slope filling phenomenon is avoided; meanwhile, the problem of manual silo cleaning is solved; and when a granary is full, the effects of ventilation and temperature reduction can be realized according to the grain and weather conditions so as to ensure safe grain storage.
Description
Technical field
The utility model relates to the storing steel silo, especially relates to a kind of large-diameter steel plate silo fluidisation discharging ventilating system.
Background technology
At present, along with the emergence of China's grain processing industry, the silo construction develops rapidly, and the application of steel silo is more extensive.At grain processing (flour, grease, feed), chemical industry, brewage, visible everywhere steel silo week of industry such as pharmacy stock relocation, and construction scale is increasing, the diameter of steel silo is also increasing.Only in this way, ton-grain storehouse Installed capital cost just can reduce, and could produce good economic benefit and social benefit.But, because the increasing of steel silo diameter is smooth and easy for guaranteeing to unload (grain) material, need to improve the height of steel silo basic platform, both increased civil engineering costs, also need bigger fill slope angle, reduce single holding capacity of bin, also needed simultaneously manually to bring down stocks, increased storage cost.
Summary of the invention
The purpose of this utility model be to provide a kind of reduce construction investment, with the supporting steel silo tube fluidisation discharging ventilating system of large-diameter steel plate silo.
For achieving the above object, the utility model can be taked following technical proposals:
Steel silo fluidisation discharging ventilating system described in the utility model, comprise by Cang Ding, the steel silo warehouse that surrounds at the bottom of bulkhead and the storehouse, described storehouse is backed down and is provided with air vent, be that the center is low at the bottom of the described storehouse, high all around cone structure, center at the bottom of described storehouse offers discharge port, evenly be provided with the V-shaped flow groove that is tilted to bulkhead along discharge port, described warehouse bottom is provided with the annular passage that is connected with outside wind regime along bulkhead, below described V-shaped flow groove, offer the branch air duct that is connected with described annular passage, sieve plate and the warehouse intracavity inter-connection of described branch air duct by being arranged on the V-shaped flow trench bottom is provided with air door at the air inlet place of described each branch air duct.
The sieve size of described sieve plate is 1.27～1.5mm.
Gradient at the bottom of the described storehouse is 15 °.
Described outside wind regime is a blower fan.
Advantage of the present utility model is the steel silo for diameter big (more than the φ 12m), can effectively reduce the basic platform height of steel silo, reduces civil engineering costs, has also avoided big fill slope (minimizing holding capacity of bin) phenomenon; Solve and substituted China simultaneously and brought down stocks the problem that auger do not pass a test and need manually bring down stocks; Silo can also play ventilation, cooling effect according to grain feelings and weather conditions when buying securities with all one's capital, guarantee safe grain storage.
Annular passage that the warehouse bottom is provided with and the branch air duct that is arranged on each V-shaped flow groove below that communicates with annular passage, each branch air duct is by the sieve plate and the warehouse intracavity inter-connection of V-shaped flow trench bottom; During discharging, when material flows to natural angle of repose in the storehouse, start outside wind regime, open the branch air duct air door successively, make material be in fluidized state in the V-shaped flow groove, smooth and easy row is to discharge port, like this and the like, can will can not lean on the material of gravity flow to clean out in the storehouse; Under its auxiliary promotion, need not bigger fill slope angle and also can guarantee the material cleaning fully, need not manually to bring down stocks, reduced storage cost.The utility model is opened each branch air duct air door and top, storehouse air vent when buying securities with all one's capital simultaneously, makes air-flow overcome the material resistance, uniformly by sieve plate and material, to reach ventilation purpose.
The sieve size of sieve plate is that 1.27～1.5mm(decides according to material properties), can guarantee ventilation effect, do not cause material to bleed in the branch air duct again.
Gradient at the bottom of the described storehouse is 15 °, has avoided big fill slope, can reduce civil engineering cost, increases holding capacity of bin.
Described outside wind regime is a blower fan.According to actual warehouse capacity, a typhoon machine provides wind regime can for one or more discharging ventilating system.

Fig. 2 is that Figure 1A-A is to view.
Fig. 3 is the structural representation in air channel at the bottom of the storehouse.
Embodiment
As Figure 1-3, steel silo fluidisation discharging ventilating system described in the utility model, comprise by top, storehouse 1, the steel silo warehouse that surrounds at the bottom of bulkhead 2 and the storehouse, described storehouse is backed down and is provided with air vent 3, be that the center is low at the bottom of the described storehouse, high all around cone structure, center at the bottom of described storehouse offers discharge port 4, evenly be provided with the V-shaped flow groove 5 that is tilted to bulkhead 2 along discharge port 4, described warehouse bottom is provided with the annular passage 6 that is connected with outside wind regime along bulkhead 2 inboards, below described V-shaped flow groove 5, offer the branch air duct 7 that is connected with described annular passage 6, the sieve plate 8 and warehouse intracavity inter-connection of described branch air duct 7 by being arranged on V-shaped flow groove 5 bottoms is provided with air door at the air inlet place of described each branch air duct 7; The sieve size of described sieve plate 8 is 1.27～1.5mm; Gradient at the bottom of the described storehouse is 15 °; Described outside wind regime is a blower fan.
The utility model and the supporting use of major diameter grain storage steel silo when buying securities with all one's capital the grain discharging, need not to start this device, and grain directly delivers from godown from discharge port under action of gravity, is transported to job shop.When grain flows to natural angle of repose, restart this device: at first open a branch air duct, all the other branch air duct air door Close Alls start blower fan, and wind-force carries out the clear grain of fluidisation in annular passage enters the branch air duct of opening; After the grain on first branch air duct cleans out, open second branch air duct again, close first branch air duct, such and the like, just can will can not lean on the grain of gravity flow to clean out in the storehouse.During actual the use, the dust in the periodic cleaning sieve plate mesh hole, guarantee the work of carrying out of this system's normal reliable.
The utility model can also under the situation of buying securities with all one's capital, be opened all branch air ducts according to grain feelings and weather conditions, starts blower fan grain in the storehouse is carried out powerful force ventilation, thereby reduce the grain temperature, guarantees safe grain storage.
