Abstract
The utility model discloses a fire protection smoke-discharging fan box, which comprises a machine casing, a fan and a motor, wherein the fan and the motor are arranged in the machine casing. The fire protection smoke-discharging fan box is characterized in that two sides of the machine casing are respectively provided with a wind inlet and a wind outlet, a sound damping panel is arranged in the casing, two ends of a fan impeller are provided with current collectors, the motor is arranged on the machine casing and fixed on a base together with the machine casing, the motor is connected with the fan through a belt, and a belt cover is arranged outside the belt. The fire protection smoke-discharging fan box is manufactured by adopting the principle of a cabinet type centrifugal machine, thereby improving the effect of smoke-discharging and aeration. Simultaneously, the motor is externally arranged, thereby avoiding aging of the motor and the belt in a flue gas pipeline and prolonging service life. Moreover, the base is designed into a damping device, thereby reducing noises in working. The structure is simple and reasonable, the noises are low, the service life is long, and the working efficiency is high.
Description
Technical field:
The utility model relates to the smoke exhaust fan case, belongs to the technological improvement of blower fan.
Background technique:
At present, the sudden and violent problem of leaking of Architecture Design fire-fighting purging system is a lot, and particularly the high building fire fighting purging system is fine or not extremely important, and many fire are because the very serious consequence of bad generation of purging system.In the fire-fighting purging system, smoke exhaust fan is its core component, and the stability of work is determining the quality of whole system.The general fire-fighting axial-flow blower that uses is discharged fume in the heavy construction at present, and smoke discharging effect is good, but wants supporting ventilation Fan Equipment to use, and has increased the cost of ventilation equipment.So fire-fighting smoke evacuation centrifugal blower occurred, discharge fume and change wind and carry out simultaneously, played fire-fighting smoke discharging effect preferably.But existing smoke exhaust fan is non-refractory work when breaking out of fire, and continuous operating time is short, can not reach good smoke discharging effect.Noise was big when in addition, existing smoke exhaust fan was worked, volume is big, be not easy to installation.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology, and a kind of smoke exhaust fan case is provided, and design is unique, and is simple in structure, elegant in appearance, the noise that is produced in the time of effectively reducing air box work.In order to achieve the above object; The technological scheme of the utility model is following: a kind of smoke exhaust fan case, and comprise casing, be installed in blower fan and motor in the casing, it is characterized in that: the both sides of casing are respectively equipped with intake grill and exhaust outlet; Be provided with in the housing and eliminate the noise and plate; The draught fan impeller two ends are provided with slip ring, and motor is installed on the casing, are fixed on the vibration damping base together with casing.
Described motor connects blower fan through belt, and belt is provided with belt housing outward, can protect belt not by pollutions such as dusts, has also played the safety protection effect.
Beneficial effect: the utility model adopts the principle of cabinet type centrifuge to process the smoke exhaust fan case; Not only increased the effect of smoke evacuation ventilation, simultaneously, electric machine external has been avoided motor and belt wearing out in fume pipe; Improved working life; Simultaneously, base designs is become vibration damping equipment, the noise when having reduced work.Simple and reasonable, noise is low, long service life, high working efficiency.
Description of drawings:
Fig. 1 is the plan view of the utility model;
Fig. 2 is the side view of the utility model.
Among the figure: 1, exhaust outlet, 2, the noise elimination panel, 3, casing, 4, intake grill, 5, motor, 6, belt 7, blower fan, 8, the vibration damping base, 9, slip ring, 10, belt housing, 11, draught fan impeller.
Embodiment:
Embodiment: see illustrated in figures 1 and 2ly, a kind of smoke exhaust fan case comprises casing 3, is installed in blower fan 7 and motor 5 in the casing 3; Described casing 3 comprises exhaust outlet 1, intake grill 4 and noise elimination panel 2; Slip ring 9 is equipped with at draught fan impeller 11 two ends of blower fan 7 the insides, and motor 5 is fixed on the casing 3, is fixedly mounted on the base 8 together with casing 3; Motor 5 connects blower fan 7 through belt 6, and belt housing 10 is housed on the belt 6.
Change in order to solve the existing existing smoke evacuation of smoke exhaust fan case that wind efficient is not high, effectiveness in vibration suppression is poor, noise is big, the problem of unreasonable structure; The utility model adopts cabinet type casing, offers bigger intake grill 1 and exhaust outlet 4 on the casing, and blower fan 7 is installed in the cabinet type casing 3; Noise elimination panel 2 is installed in the housing of casing 3; At draught fan impeller 11 two ends slip ring 9 is installed, has been improved the smoke evacuation of smoke exhaust fan case and changed wind efficient, the noise that has been produced when greatly having reduced blower fan work; Simple in structure, elegant in appearance.Motor 5 and casing 3 are fixed on the base 8, and described base 8 has certain effectiveness in vibration suppression, the vibrating noise that has been produced when so just having solved blower fan and machine operation.In addition, pulley cover 10 protection belts are not polluted by extraneous dust and other impurities, have increased Security again.
