ガイドベーンを持った採風口を設けた貯蔵施設である。The present invention was created to eliminate the drawbacks of conventional storage facilities as described above, and provides a storage facility that prevents the generation of dust, has a simple structure, and is inexpensive. This is a storage facility in which a wall is formed around the stored powder and granular material, and an air intake with a guide vane is provided on the upper part of the peripheral wall.

通常コンクリート、レンガ、木材。A specific example of the present invention will be explained with reference to the drawings. In FIG. 1, a peripheral wall 1 is provided around a powder 2, and the peripheral wall 1 is usually made of concrete, brick, or wood.
合成樹脂あるいは鉄板等で形成されるが、耐久性のある
ものであれば、いかなる材質でも使用される。It is made of synthetic resin or iron plate, but any durable material can be used.

蔵されるのが有効である。Further, as shown in Fig. 2, a ventilation opening 3 having a guide vane 4 for taking in wind is provided at the upper part of the peripheral wall 1, and the powder and granular material 2 to be stored is placed below the ventilation opening and in the shape of a mortar. It is effective to store it in
採風口３の形状、大きさ、数は貯蔵所の立地条件、即ち
Ｊｕｌ量、風向き、又貯蔵物の種類、特性。The shape, size, and number of the ventilation ports 3 depend on the location conditions of the storage facility, such as the amount of air flow, wind direction, and the type and characteristics of the stored items.
即ち粒径、比重で決定される。That is, it is determined by particle size and specific gravity.
ガイドベーン４は貯蔵所内に渦巻き風を発生するために
設けられるものである。The guide vanes 4 are provided to generate swirling wind inside the storage area.

される。As shown in Figure 3, the wind collides with the guide vane 4,
The direction of the airflow is changed by 11 and guided into the peripheral wall 1, a swirling flow is generated along the peripheral wall 1, and a rare Zan clone is formed.

可能である。In order to efficiently generate a swirling flow, the guide vane 4 is
Although it is installed with a moderate inclination, the best conditions for generating swirling flow are selected depending on the location of the storage facility and the type of stored items. Note that this guide vane 4 is not limited to the one in this embodiment, but may be implemented in various shapes in order to effectively generate swirling flow. Also in the wind direction J: Reguide vane 4
It is also possible to install the device so that the air intake port 3 can be opened and closed by rotating.

飛散する事がない。When a wind is generated, the stored powder 1 is given a swirling flow by the wind introduced from the air intake port 3, and falls downward while rotating along the peripheral wall 1, so that most of the stored powder and granular material 1 is not stored. There will be no scattering outside the facility.
