Description
【発明の詳細な説明】
こp=t、100° Cから200° C程度ノ高温ガ
スを軸流送風機により、通風させる為のものである。DETAILED DESCRIPTION OF THE INVENTION This is for ventilating gas at a high temperature of about 100° C. to 200° C. using an axial flow blower.
従来、高温ガスの通風の目的には、遠心式送風機を使用
するか、モーター外装り字型軸流送風機を使用していた
が、これらの送風機は、すえつけ面積を多く必要とし、
通気方向は、構造上、−直線のダクト上には、設備不可
能である。Conventionally, centrifugal blowers or axial flow blowers with an external motor have been used to ventilate high-temperature gases, but these blowers require a large installation area;
Due to the structure, the ventilation direction cannot be installed on a straight duct.
この発明は、従来の実状に鑑みて、余分な取付スペース

されない時は、1枚羽根とする。Two impellers 4 for blowing high-temperature gas are attached to Wlm of the electric motor 2 in order to increase the wind pressure, and a cooling fan 4+1' and a cooling plate 7 are also provided to protect the electric motor 2 from high temperatures. , a cold air guide cover 6 is provided to prevent heat radiation from the high temperature passage 8 and to efficiently pass cold air. A, Terukin” shows the ventilation of outside air that cools the electric motor, and is sucked in by the cooling fan 5, and is drawn into the partition plate 14.
The air is guided by the cooling guide cover 6 and vented from A to the mouth. At this time, the electric motor 2 is cooled by the outside air. The wind cylinder 1 has a motor 2 fixed thereto by a motor holder 11 via a wind cylinder par 9 and a motor support 10. Both ends of the wind barrel 1 are provided with flanged end pipes 12,13. C, 2 shows ventilation of high temperature gas, impeller 4
It is pumped in two directions from C. In this figure, two blades are shown to increase wind pressure, but if high wind pressure is not required, one blade is used.
