Abstract
The utility model relates to a mixed-flow smoke-discharge blower for fire control, which comprises a machine shell, an impeller, a motor, an air gathering opening and an air discharging opening. The utility model is characterized in that the impeller is arranged behind the air gathering opening in the machine shell, a motor chamber is arranged behind the impeller and the impeller is connected with a motor in the motor chamber. An air path is arranged between the motor chamber and the machine shell, the motor chamber is provided with an air inlet and an air outlet. The motor is connected with a centrifugal impeller. The utility model has the advantages that a common blower device can continuously operate with 40 minutes in the high temperature smoke of 280 DEG C under the condition that a fire is in a large building to satisfy the requirements of the smoke discharge of the fire control.
Description
Technical field
The utility model relates to a kind of smoke exhaust fan, particularly a kind of mixed flow smoke exhaust fan.
Background technique
The general fire-fighting axial-flow blower smoke exhaust when breaking out of fire of using in the heavy construction at present, but because the Fan Equipment of ventilation needs with the fire-fighting axial-flow blower time, will cause the cost of the ventilation equipment in the building to rise, and existing ventilation blower fan can't be finished the task of fire-fighting smoke evacuation.
Summary of the invention
The purpose of this utility model is to solve the general fire-fighting axial-flow blower smoke exhaust when breaking out of fire of using in the medium-and-large-sized building of prior art, but because the Fan Equipment of ventilation needs with the fire-fighting axial-flow blower time, will cause the cost of the ventilation equipment in the building to rise, and existing ventilation blower fan can't be finished the problem of the task of fire-fighting smoke evacuation.The utility model design mixed flow smoke exhaust fan, comprise casing, impeller, motor, collection air port, exhaust outlet, it is characterized in that: behind casing Nei Ji air port, be impeller, it behind the impeller motor room, impeller connects the motor in the motor room, between motor room and casing the air channel is arranged, suction port and air outlet are arranged in the motor room, motor connects centrifugal impeller.The utility model has the advantages that the Fan Equipment that can make at ordinary times can turn round 40 minutes under the situation of heavy construction breaking out of fire continuously, satisfied the demand of fire-fighting smoke evacuation under 280 ℃ high-temperature flue gas.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated, accompanying drawing is a structural representation of the present utility model,
Comprise casing 1, impeller 2, motor 3, collection air port 4, exhaust outlet 5 among the embodiment figure, it is characterized in that: be impeller 2 in 4 backs, casing 1 Nei Ji air port, impeller 2 backs are motor room 6, the motor 3 that impeller 2 connects in the motor room 6,1 of motor room 6 and casing have air channel 7, suction port 8 and air outlet 9 are arranged in the motor room 6, and motor 3 connects centrifugal impeller 10.Using flue gas or waste gas to enter impeller 2 pressurizations from collection air port 4,7 discharge from the air channel again from exhaust outlet 5, if what suck is high-temperature flue gas, motor 3 in the motor room 6 drives centrifugal impeller 10, new wind is sucked motor room 69 discharges from the air outlet again from suction port 8, reduce the temperature in the motor room 6, guarantee the normal operation of motor 3, blower fan can be turned round 30 minutes under 280 ℃ high-temperature flue gas continuously, satisfy the demand of fire-fighting smoke evacuation.
