Description

Przewietrznik niniejszy sluzy dó wdmu¬ chiwania powietrza lub innych gazów do palenisk i pieców hutniczych, o zwiekszo¬ nej preznosci przy zastosowaniu mniejszej ilosci obrotów, wzglednie mniejszych wy¬ miarów w porównaniu do znanych prze- wietrzników o tej samej ilosci powietrza* Na rysunku fig* 1 wskazuje przekrój przez kolo c; fig- 2 — 'przekrój poziomy przewietrznika; fig, 3 — widok kola a wglednie b; fig. 4 — ulozenie lopatek po rozwinieciu.Przewietrznik sklada sie z trzech kól lopatkowych, z których dwa kola ze¬ wnetrzne a i b obracaja sie w tym samym kierunku i przesuwaja powietrze równo¬ legle do osi przewietrznika oraz z kola c obracajacego sie w kierunku przeciwnym, dzialajacego odsrodkowo (fig. 3 i 4). PL PLThis ventilator serves for blowing air or other gases into furnaces and metallurgical furnaces, with increased speed using a lower number of revolutions, relatively smaller dimensions compared to known ventilators with the same amount of air. 1 indicates a section through circle c; Fig-2 - 'horizontal section of the ventilator; Fig. 3 is a view of a wheel a, specifically b; Fig. 4 - position of the blades after unfolding. The ventilator consists of three paddle wheels, of which two external wheels a and b rotate in the same direction and move the air parallel to the axis of the ventilator and from the wheel rotating in the opposite direction, centrifugally (Figs. 3 and 4).

Claims

1. Patent claims. 1. A ventilator with three paddle wheels, characterized in that the two extreme paddle wheels rotate in one direction and move the air axially, while the center wheel rotates in the opposite direction and sets the air in a centrifugal motion.

2. Ventilator according to claim 1, characterized in that the central paddle wheel has a larger diameter or rotates with a greater number of revolutions than the outermost wheels,

A ventilator according to claims 1 and 2, characterized by the fact that the edges of the blades of the outer wheels and the center wheel are inclined towards each other so as to move similarly to the blades of the scissors rotating about a common pin.

4. Ventilator according to claim 1 - 3, characterized by the fact that the blades of the central wheel are trough-shaped, Józef Kiec. Fryderyk Klementys. LIBRARY Urzedu Pateatowege Rzeczyp ^ olilsj Polskiejx ~ III 521 co I O o PL PL
