Abstract

The utility model provides an automatic ventilation device, which is arranged on a grain storage warehouse used for eliminating moisture hot gases in the storage granary. A forced ventilation device is not arranged in the existing grain storage warehouse. Thus, the existing grain storage warehouse has a poor storage effect. Besides, the existing grain warehouse has need of warehouse reversion and drying. Therefore, the existing grain storage warehouse has the defects of large manpower consumption and large material resource consumption. The automatic ventilation device of the utility model utilizes natural wind to drive a wind draught arranged on an air discharging opening of a granary so as to eliminate hot moisture air in a grain warehouse in a forced way. Therefore, grains can be kept in a good storage state. The utility model has no need of other energy sources, can lie in a good operation state for a long time and has the advantage of obvious air elimination effect.

Description

Automatic ventilation equipment

Technical field

The utility model relates to a kind of automatic ventilation equipment that is used in the granary.

Background technology

The grain that granary is interior is easy to heating, goes mouldy owing to contains certain moisture in the storage, causing rotten can not eating, so necessary well-ventilated in the granary is controlled under the certain level moisture of grain in the storehouse and temperature.Because present granary mostly is not equipped with ventilation unit, must store up airing to the grain in the storehouse, has expended great amount of manpower and financial resources, although the part silo is provided with ventilation shaft, but all be to rely on gravity-flow ventilation, effect is bad, and the moisture in the storehouse, hot gas can not be discharged rapidly and thoroughly.

Summary of the invention

The utility model proposes a kind of automatic ventilation equipment that is used for granary, it can utilize natural wind-force to turn round voluntarily, forces the hectic fever air in the pump drainage granary, makes that grain is in good keeping state in the storehouse.The utility model is made up of trunk line, branch pipe(tube) and the draught fan by wind force that is installed in the trunk line upper port, trunk line is vertically mounted in the granary, stretch out outside the roof, warehouse its upper end, rear portion air inducing sleeve pipe by a bearing and draught fan by wind force is linked together, one cantilever is housed on the air inducing sleeve pipe, hangs the bearing block of draught fan by wind force, the driving blade and the air draft blade of air-introduced machine are divided in the bearing two ends, air-introduced machine can be done 360 ° of revolutions under the wind-force effect, keep best operational position.The part of horizontal of trunk line in bin connects a plurality of branch pipe(tube)s, has many exhaust holes on the branch pipe(tube), and the branch pipe(tube) other end stretches out outside the storehouse, to maintain the circulation of air.The utility model does not need the energy except that wind-force, and effectively the hectic fever air in the pump drainage granary makes granary keep good ventilation state forever.

Description of drawings

Fig. 1 is a schematic diagram of the present utility model, and (1) is trunk line, and (2) are branch pipe(tube), and (3) are draught fan by wind force, and (4) are granary.

Embodiment

In granary, place a standpipe, adopting external diameter is the thin-wall steel tube of φ 100, riser upper is stretched out the roof of granary, at its head 6220 bearings are installed, the air inducing sleeve pipe of draught fan by wind force is installed on bearing outer ring again, welding one cantilever on the air-introduced machine sleeve pipe, the underslung bearing seat, to support the driving blade and the air draft blade of draught fan by wind force, make draught fan by wind force change duty along with wind direction changes simultaneously, draught fan by wind force is axial horizontal arrangement, and the driving blade is a double leaf, and the air draft blade is leafy.On standpipe, divide four layers each make a call to the eyelet of two φ 60, each eyelet level is welded the steel pipe of an external diameter φ 60, the steel pipe other end stretches out outside the storehouse.

Claims

1. an automatic ventilation equipment is used in the granary, and trunk line and branch pipe(tube) are housed, and it is characterized in that:; Trunk line stretches out the outer port of bin and by the bearing connection one draught fan by wind force is housed.

2. an automatic ventilation equipment as claimed in claim 1 is characterized in that: on the air inducing sleeve pipe of draught fan by wind force a cantilever is housed, hangs the bearing block of draught fan by wind force.
