Abstract
The invention discloses a fire-fighting centrifugal fan, which comprises a box body with an air inlet and an air outlet, wherein a scroll case is arranged in the box body; a motor is fixedly arranged on the box body; the motor drives an impeller in the scroll case to rotate by a triangle belt; impeller blades are distributed on the inner circumference of the impeller uniformly; the box body has a duplex plate structure; and a heat-insulating layer is arranged in a duplex plate. The fire-fighting centrifugal fan has high operating stability, and can run continuously at the high temperature of 300 DEG C for over 60 minutes.
Description
Technical field
The present invention relates to a kind of centrifugal blower, especially relate to a kind of fire-fighting centrifugal blower.
Background technique
At present, the sudden and violent problem of leaking of Building Fire Protection purging system is a lot, and particularly the fire prevention to high buildings purging system is fine or not extremely important, and a lot of fire are because of the very serious consequence of the bad generation of purging system.Present tall building much all is provided with the fire-fighting purging system, discharges a large amount of poisonous dense smoke that the fire burning produces.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.Existing smoke exhaust fan is many because of the combustion product gases temperature reaches 200-300 ℃ of poor work stability, and continuous operating time is short, can not reach good smoke discharging effect.The cabinet type centrifugal blower of a kind of fire-fighting is disclosed as Chinese patent 02292875.8, comprise casing, spiral case, impeller, motor, air intake flange, outlet air flange, impeller shaft is connected with casing by high temperature resistant bearing, motor is positioned at the casing top, and motor is connected by belt by belt pulley with impeller shaft.Though motor is arranged in the outside of casing, because the casing temperature is very high, motor is worked under hot environment, poor stability.
Summary of the invention
The purpose of this invention is to provide a kind of fire-fighting centrifugal blower, solve existing fire-fighting and make poor stability, the problem that continuous operating time is short with the centrifugal blower multiplex (MUX).
The technical solution adopted for the present invention to solve the technical problems is: a kind of fire-fighting centrifugal blower, comprise the casing that is provided with intake grill and exhaust outlet, be provided with spiral case in the described casing, be set with motor above the described casing, described motor is evenly equipped with impeller blade by the wheel rotation in the v belt driving spiral case on the described impeller inner circumference; Described casing is compound plate structure, is provided with thermal-protective coating in the middle of the described compound plate.
Further, described spiral case material is zinc-plated steel plate.
In order to improve the smoke evacuation air quantity, described impeller is a multiple wing forward curved vane structure.
Beneficial effect of the present invention:, the isolation of motor and high temperature purging system is separated because fire-fighting of the present invention is arranged on the outside of casing with the motor of centrifugal blower.Advantages such as and casing is compound plate structure, is provided with thermal-protective coating in the middle of the compound plate, and it is high temperature resistant that it is had, and noise is little.Guarantee that blower fan can move more than 60 minutes the blower fan good operating stability continuously under 300 ℃ of high-temperature conditions.This blower fan is through " it is qualified that fixing fire extinguishing of country and fire retarding component quality inspection " center " detect, and its performance reaches advanced international level.
Below with reference to drawings and Examples, the present invention is carried out comparatively detailed explanation.

Fig. 2 is the sectional view of fire-fighting of the present invention with centrifugal blower.
Among the figure: 1. casing, 2. motor, 3. v belt, 4. thermal-protective coating, 5. spiral case, 6. impeller, 7. impeller blade, 8. impeller shaft, 9. bearing support.
Embodiment
Among the present invention, fire-fighting is arranged on the outside of casing with the motor of centrifugal blower, motor and high temperature purging system is isolated separate.Advantages such as and casing is compound plate structure, is provided with thermal-protective coating in the middle of the compound plate, and it is high temperature resistant that it is had, and noise is little.Guarantee that blower fan can move more than 60 minutes the blower fan good operating stability continuously under 300 ℃ of high-temperature conditions.
