Abstract

Изобретение относитс к технике вентил ции и позвол ет улучшить услови труда путем регулировани выт жки воздуха по площади входного отверсти при выполнении его пр моугольной формы. Перфорированна вставка 4, размещенна во входном отверстии 2, выполнена в виде отдельных пластин (П) 7 со сплошными боковыми полками 8. По длине отверсти 2 расположена ось 6. П 7 установлены на оси с возможностью относительного поворота . Упоры с внутренней стороны корпуса 1 взаимодействуют с П 7, На оси свободно установлены втулки 10, кажда из которых размещена между полками 8. Вставка дает возможность измен ть объем выт жного воздуха по площади отверсти 2 за счет поворота П 7 на оси. При этом П 7 удерживаютс в заданном положении благодар тому, что втулки и полки П 7 плотно прижимаютс друг к другу. 1 з.п. ф-лы, 3 ил. с €The invention relates to a technique of ventilation and allows to improve working conditions by adjusting the exhaust air over the area of the inlet when it is rectangular in shape. The perforated insert 4, placed in the inlet 2, is made in the form of separate plates (P) 7 with solid side shelves 8. The axis 6 is located along the length of the hole 2. The P 7 are mounted on the axis with the possibility of relative rotation. The stops on the inner side of the housing 1 interact with the P 7. The sleeves 10 are freely mounted on the axis, each of which is located between the shelves 8. The insert allows you to vary the volume of exhaust air over the area of the hole 2 by rotating P 7 on the axis. In this case, the П 7 are kept in a predetermined position due to the fact that the sleeves and the shelves P 7 are tightly pressed against each other. 1 hp f-ly, 3 ill. from €

Claims

Claim

1. An exhaust hood comprising a housing with an inlet and an outlet, a perforated insert placed in the opening, forming a gap with the housing, characterized in that, in order to improve working conditions by adjusting the hood over the area of the inlet while making it rectangular shaped, the housing is equipped with an axis located along the length of the hole, and the insert is made in the form of separate 30 plates with continuous side floors. Polluted air enters the housing 1 through the perforated insert 4 and the gap 5 formed by the insert s 4 and the housing 1. Because the housing 1 the contaminated air is removed through the outlet 3.

The insert, consisting of individual plates 7, makes it possible to vary the volume of exhaust air over the area of the cabs mounted on the axis with the possibility of relative rotation.

2. The umbrella according to claim 1, characterized in that the housing on the inner _35th side is provided with stops interacting with the plates, and the axis is provided with bushings freely mounted on it, each of which is placed between the shelves of the plates.
