Abstract

The improved structure comprises a front box, a pipe sleeve is fixed to the side wall of the front box, a rear box is fixed to the end of the pipe sleeve, a machine sleeve is fixed to the side wall of the front box and the side wall of the rear box together, a motor is fixed to the inner wall of the machine sleeve, the motor is a double-end motor, and the two ends of the machine sleeve are connected with the two ends of the machine sleeve. A rear fan blade and a front fan blade are fixed to two output shafts of the motor respectively and located in the rear box and the front box respectively, a plurality of inner through pipes and outer through pipes which are communicated with the interior of the rear box are inserted into the side wall of the front box in a penetrating mode, and the inner through pipes are located in the pipe sleeve. The device has the advantages that the temperature is controlled after the air flow is exhausted, direct pollution to the environment is reduced, the smoke treatment difficulty of follow-up equipment is reduced, heat generated by the motor during operation can also be absorbed by water flow, the motor keeps the effective operation temperature, the motor does not make direct contact with the air flow, the damage speed of the motor is greatly reduced, and the service life of the motor is prolonged. And the service life of the motor is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an improved structure of an axial-flow high-temperature exhaust fan. Background technique [0002] Axial flow fan is also called local fan. It is different from ordinary fans. Its motor and fan blades are in a cylinder. The shape is a cylinder. It is used for local ventilation. , you can connect the air tube to send the wind to the designated area. [0003] After the existing axial flow fan is installed, it is usually used to discharge high-temperature flue gas, especially in the field of fire protection. Because the driving parts of the existing fan are in direct contact with the air flow, the high-temperature flue gas can easily cause direct impact on the driving parts Damage, which greatly reduces the service life of the driving components, and is extremely easy to damage, which leads to inconvenience in the use of equipment, and the existing equipment cannot restrain the emissi...
