Abstract

The invention belongs to the technical field of draught fans and particularly relates to a draught fan for metal smelting. The draught fan comprises a rack, a three-way air guiding tube, a transmission module and two air supply modules, wherein the transmission module is mounted on the front side of the rack; the two air supply modules are mounted on the two sides of the transmission module and onthe front side of the rack; the three-way air guiding tube is mounted above the transmission module and on the front side of the rack; the two side arms of the three-way air guiding tube communicatewith the two air supply modules separately; a motor is mounted on the rear side of the rack and is in transmission connection with the transmission module; the transmission module comprises a drivingwheel, a driven wheel, a two-sided rack and an arc-shaped gear wheel; the two ends of the two-sided rack extend into the two air supply modules separately; and a thread disc, a switch unit and a closing unit are sequentially arranged in each of two air supply tubes. The draught fan utilizes the air supply tubes to discharge hot-blast air in an uninterrupted manner; and in addition, the two air supply tubes convey the air alternately, so that cooling of the air supply tubes is facilitated, the service life of the air supply tubes is prolonged, and normal hot-blast air supply operation is ensured.

Description

technical field [0001] The invention belongs to the technical field of fans, in particular to a fan for metal smelting. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas conveying machinery in China. Usually, fans include ventilators, blowers, and wind generators. Fans are mainly used in metallurgy, petrochemical, electric power, urban rail transit, textile, shipbuilding and other fields of national economy and ventilation in various places. During metal smelting, it is necessary to use a fan to introduce hot air into the burner. [0003] There are also some technical solutions for fans in the prior art. For example, a Chinese patent with application number 2016108181396 discloses an externally driven heat-insulated and high-temperature-resistant suction fan, which is welded with an "L"-s...
