Abstract

The utility model relates to a natural ventilating device for grain storehouses, which can change horizontal wind into vertical flowing air flow to force air in a grain storehouse to circulate. The utility model is characterized in that a radial outward flow turbine (3) is connected with an exhaust fan (7) via a bearing (5) through a shaft (4); the bearing (5) is fixed on a grain storehouse supporting frame (6). When a ventilating hole (2) on the upper part of the grain storehouse is blown with wind, the radial outward flow turbine (3) rotates to drive the exhaust fan (7) to generate vertical flowing air flow, air in the grain storehouse can be exchanged with outside air through a convection window opened on the grain storehouse.

Description

Natural ventilating device for grain storehouse

The utility model relates to a kind of silo natural ventilator, specifically, relates to a kind of with the power-actuated ventilation equipment that is used for silo of natural wind.

Be stored in the cereal in the silo, can give out a lot of heats and wet gas, so in silo in the past, the vent hole of some can be arranged all, these vent holes are distributed in the bottom and the top of silo, air in the silo are carried out the exchange of natural recirculating type by the hot-air convection motion principle.Because after being full of cereal in the silo, air ventilation will very obstructed, so effect is not very good, still have cereal after, air ventilation will be very obstructed, so effect is not very good, the phenomenon that still exists cereal to generate heat, go mouldy.And the forced ventilation of power consumption power consumption is not suitable for again being used in the many silo equipment of number.

The purpose of this utility model is to provide a kind of with the power-actuated ventilation equipment of natural wind, and it can convert the horizontal wind-force from all directions to and be suitable for the uprush that silo ventilates, to be adapted to existing silo structure.

The purpose of this utility model is achieved like this:

A radial outward flow turbine is installed in the horizontal vent window at silo warehouse top, below radial outward flow turbine, ventilating fan of installation coaxial with it, ventilating fan rotates under the drive of radial outward flow turbine, and the air that drives in the silo flows in vertical direction.

Compare with existing silo, the wind-force that the equipment that the utility model provides has made full use of natural wind carries out forced flow to air in the silo, and ventilation effect more only utilized natural convection formula cyclical breathing to improve a lot.

Introduce a kind of embodiment who reaches the utility model purpose below in conjunction with accompanying drawing.

Fig. 1 is a silo natural ventilator structural principle schematic representation;

Fig. 2 be among Fig. 1 A-A to plan view.

Silo (1) top has vent hole (2), and radial outward flow turbine (3) is connected with ventilating fan (7) through bearing (5) by axle (4), and bearing (5) then is fixed on the silo bearing support (6).When horizontal wind-force drives radial outward flow turbine (3) rotation by vent hole (2), the ventilating fan coaxial with it (7) also rotates thereupon, play the effect that drives air perpendicular flow in the silo, the interior air of silo and the external world are exchanged by convection current window (8).

Claims (1)

1, a kind of silo natural ventilator, form with ventilating fan (7) by radial outward flow turbine (3), axle (4), bearing (5), bearing support (6), it is characterized in that, radial outward flow turbine (3) is by axle (4), be connected with ventilating fan (7) through bearing (5), bearing (5) then is fixed on the bearing support (6).
