Abstract

PURPOSE:To install an axial fan for use at high temperatures on a straight duct without requiring extra space for installation by furnishing the wind channel at its axis part with an electric motor equipped with a cooling fan and a cold air guide cover and with impellers. CONSTITUTION:A wind channel 1 is equipped with a space for installation of an electric motor 2 at its axis part and several holes 3 for introduction of cold air and fixation of the motor 2. Impellers 4 are installed at both ends of the motor 2, and further a cooling plate 7 and a cold air guide cover 6 are furnished. The wind channel 1 is fixing the motor 2 by a motor holder 11 with the aid of a wind channel cover 9 and a motor support 10. As this arrangement is equipped with a motor 2, impeller 4, etc. at the axis part of wind channel 1, the blower can be installed on a straight duct without requiring any extra space for installation.

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

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.
