Abstract

The invention relates to a jet fan for airflow movement including: two separated casings (10) composed of an exterior column (11) and an interior column (12), between which a sound deadening member (20) is provided; a accommodated tube (30) formed of polyporous plate shape and having a nozzle (31) with little livly diameter; an internal wall supported and fixed in the accommodated tube (30) for introducing the side silencer (50a) and discharging the side silencer (50b); introducing the side lid (40a) and discharging the side lid (40b); a fan box (60), in which, the motor is provided and the impeller (63) is rotated by the motor; a supported bracket (70) fixed on the two side bottom of the casing, and a plurality of feed holes are formed of arc shape with the center of the fan box (60) as reference; a fixing member whose elongation part (81) has a plurality of angle adjustment hole (82). The invention is used for introducing to deliver and exhaust air, introducing ventilation and controlling airflow pattern, and the factory is ventilated swimmingly.

Description

Technical field [0001] The invention relates to a jet fan for conveying air flow. The present invention is installed in single-type and conjoined semi-open factories in shipyards and other heavy industry fields that inevitably generate welding fumes, dust, exhaust gas, etc., to guide air supply and exhaust, guide ventilation, and control air flow spectrum , Which can smoothly ventilate the above-mentioned factories. Background technique [0002] Usually, shipyards and other heavy industry factories have large-scale single-unit and conjoined factories for indoor operations. [0003] In the above-mentioned factories, the processed materials produce a large amount of welding fumes, dust, gas, etc., which can change the working environment and are harmful to the health of workers. Therefore, it is necessary to pay more attention to the ventilation inside the factory. However, because most factories are simple Rotary electric fans are used to ventilate the inside of the factory. There...
