Abstract

The invention discloses a stable type aging furnace high-temperature-resistant axial flow fan which comprises a rectangular installation plate, a drive motor, a cooler, an impeller mechanism, a transmission shaft, an impeller shell, a cylindrical air flue, a toroidal base and a conical inner cover. According to the stable type aging furnace high-temperature-resistant axial flow fan, the conical inner cover can be matched with the cylindrical air flue so as to guide hot air, so that the air can be quickly discharged from an air outlet; the conical inner cover can be used for effectively heat-insulating and protecting the cooler; the cooler can be used for heat-insulating the transmission shaft, so that two bearings can be cooled and are prevented from being damaged by high temperature, andthe service life of each bearing is prolonged; and by utilizing a conical flow guiding cover, the front air resistance of the impeller mechanism can be reduced, the inlet air is prevented from causingthe shaking influence on the rotary stability of the impeller structure, so that the impeller mechanism is ensured to rotate stably.

Description

technical field [0001] The invention relates to an axial flow fan, in particular to a stable aging furnace high temperature resistant axial flow fan. Background technique [0002] At present, during the use of the existing axial flow fans, the rotating shaft bearings are often damaged too quickly due to high temperature, which seriously affects the service life of the fans. Therefore, it is necessary to design a stable aging furnace high temperature resistant axial flow fan, which can effectively protect the shaft bearing and prolong the service life of the fan. Contents of the invention [0003] The purpose of the invention: to provide a stable aging furnace high temperature resistant axial flow fan, which can effectively protect the shaft bearing and prolong the service life of the fan. [0004] Technical solution: The invention creates the stable aging furnace high temperature resistant axial flow fan, which includes a rectangular mounting plate, a drive motor, a coole...
