Abstract
The utility model relates to a fire-protection high temperature fan for removing smoke. The utility model belongs to an improved high temperature fan for removing smoke to remove water, which is composed of a casing, a tail cover group, a centrifugal impeller assembly, an electric motor, a heat insulating plate, an impeller assembly, an envelope, a rectifying cover and an envelope port. The utility model is characterized in that the centrifugal impeller assembly is connected with an air gathering device through the envelop port, the heat insulating plate is a multi-layer structure, and the electric motor is a one-speed, double-speed or multispeed electric motor. The utility model has high efficiency, wide adaptation range and convenient installation. The utility model is improved by integrating the opinions of wide building design institutes and user, and the utility model is a new generation of fire-fighting high-temperature smoke exhausting fan.
Description
The utility model belongs to improved fire-fighting High-temp. smoke-exhausting fan.
The centrifugal blower fan blade wheel and the clearance opening type of attachment between the wind collecting unit of the fire-fighting High-temp. smoke-exhausting fan of skyscraper employing now are the counterpart types of attachment, and the leakage of cooling air quantity is bigger; The thermal insulation board level is few, and blower fan moves under 400 ℃ of hot conditions and limited to, and influences service life; Different requirements in high-grade civil buildings and underground engineering also are restricted.
The purpose of this utility model provides a kind of fire-fighting High-temp. smoke-exhausting fan of new generation, overcomes the drawback that exists in the background technology.
The utility model is finished with following mode: it comprises casing 5, hood group 6, centrifugal impeller group 4, motor 3, thermal insulation board 2, impeller sets 1, big envelope 7, radome fairing 8, be the annulus cylindrical passageway between hood group 6 and the casing 5 and between hood group 6 and the motor 3, between hood group 6 and the casing 5 impeller sets 1 is housed, interconnect between motor 3 and the impeller sets 1 and between centrifugal impeller group 4 and the motor 3, clearance opening type of attachment between centrifugal impeller group 4 and the wind collecting unit is the counterpart type of attachment, and feature is: type of attachment is to be connected by running-on 9 between centrifugal impeller group 4 and the wind collecting unit; Thermal insulation board 2 is sandwich constructions; Motor 3 is single speed, double speed or multispeed electric machine.
Comprehensive vast Architecture Design Institute of the utility model and user's suggestion and improve the fire-fighting High-temp. smoke-exhausting fan of new generation of design, it has following characteristics:
A. the cooling centrifugal fan impeller of motor and the clearance opening form between the wind collecting unit change the running-on form into by counterpart, reduce the leakage of cooling air quantity, increase the cooling effect of motor.
B. increase flaggy number across the mature, guarantee that blower fan also can move under 400 ℃ hot conditions, prolong the service life of blower fan under hot conditions.
C. wide accommodation.Can be according to the different requirements of senior civil buildings and underground engineering, the form that adopts single speed, double speed or multispeed electric machine driving is to reach the purpose of a machine dual-purpose (discharging fume at a high speed when vented exhaust promptly commonly used and fire-fighting are used).
D. efficient height.PYF series smoke exhaust fan adopts advanced CAD system software, forms through multiple-objection optimization, and fan efficiency is greater than 80%, and the part plane No. is greater than 85%, and has the smooth characteristics of efficiency curve, helps energy-conservation.
E. easy for installation, take up an area of fewly than centrifugal blower, adopt the direct-connected mode of motor reliable.
Fig. 1 is the utility model structural representation.
Rotating shaft impeller group 1 rotation of motor 3 makes high-temperature flue gas axially suck annulus cylindrical passageway in the casing 5 from blower fan right-hand member import department, and discharge vertically in the flue gas left end exit of leading equably.Centrifugal impeller group 4 is equipped with at the blower fan rear portion, makes the blower fan work of safety continuously at high temperature.The cooling air is sucked by centrifugal impeller group 4, is discharged to the blower fan outside at last.The cooling air has been taken away flue gas and has been passed to the heat of motor 3 by interior tube outer surface like this, and the temperature restriction that can make motor 3 surfaces prolongs hot conditions following service life within the specific limits.
