Axial flow fan for coke oven dust removal system

Abstract

The invention provides an axial flow fan applied to the technical field of coke oven dust removal systems. A fan shell (1) of the axial flow fan is internally provided with a fan shaft (2). The fan shaft (2) is provided with fan blades (3). The end, stretching out of the fan shell (1), of the fan shaft (2) is provided with a bevel gear I (4). The bevel gear I (4) is meshed with a bevel gear II (5). The bevel gear II (5) is connected with one end of a transmission shaft (6). The other end of the transmission shaft (6) is connected with a motor (7) capable of driving the transmission shaft (6) to rotate. The axial flow fan has the advantages of being simple in structure, capable of adapting to the high-temperature and dirty environments of the axial flow fan, capable of avoiding the problems that a conveying belt is prone to slipping and aging in the conveying process, stable in transmission, accurate in transmission ratio, reliable in work, high in efficiency, long in service life, large in using power and size range and high in speed.

Description

Technical field [0001] The invention belongs to the technical field of coke oven dust removal systems, and more specifically, relates to an axial flow fan used for coke oven dust removal systems. Background technique [0002] The axial flow fan is the key equipment of the coke side dust removal system of the coke oven. Through the operation of the axial flow fan, the smoke and dust dispersed on the coke side of the coke oven is sucked and transported to the dust removal pipeline. The working environment of the axial flow fan for coking and dust removal is: high temperature and dust; the ambient temperature is 150℃, and the short-term high is 400℃. The transmission mode of the axial flow fan in the prior art is as follows: a belt transmission with an equal diameter pulley and a flexible lap belt is adopted; the motor is installed directly above the casing of the axial flow fan, and the axis of the motor is parallel to the axis of the axial flow fan. On the outside of the pulley a...
