Description
Technical field
The utility model relates to a kind of ventilation equipment class technical field, especially a kind of fire-protection high temp.
Background technique
After fire fire-fighting fire extinguishing occurs in floor, smog and water mist take a long time to carry out nature volatilization to disappear because of ventilating problem
It dissipates, so the smog in floor after fire extinguishing, can be retracted to outside using the blower of several drawing-in types, adopted by fire fighters
The blower of drawing-in type is conventional formula, first is that extracting force is small, no pressurization, smoke exhaust efficiency is not high enough, can only be passed through for a long time
Suction operation is to implement to solve；It is straight such as blower second is that the area of the air inlet of blower directly depends on the diameter of blower
Diameter is 100mm, and the initial air inlet diameter of that blower is also 100mm, and the area diameter of the initial smoking mist of blower is also
The smog of 100mm, remaining place can only collect then lasting row by the initial air inlet of air pressure toward the blower formed in suction
Out, the efficiency of smoking and the smoke evacuation of blower can not be increased.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of fire-protection high temp,
Including axial flow blower, outlet housing, suspended hood, heap high trestle, pedestal, double end motor is set in axial flow blower, double end motor both ends
The fixed fan blade of rotary shaft, axial flow blower lower end set heap high trestle and pedestal, and the air intake connection of axial flow blower sets wide-mouth air inlet
The suspended hood of chamber, outlet air end connect outlet housing, and outlet air is provide with the pressurization wind chamber that diameter is gradually reduced to air outlet, the utility model
Air inlet is wide, sends out after the pressurization of the outlet housing of taper after capable of quickly sucking the smog of large area, substantially increases smog
Suction and discharge efficiency are suitable for fire-fighting evacuation smog in floor and peace and quiet smog application are discharged.
In order to achieve the above objectives, the utility model provides a kind of fire-protection high temp, including axial flow blower, outlet air
Cover, suspended hood, heap high trestle, pedestal set double end motor in the axial flow blower, and the double end motor external application connecting bracket is in wind
The inner wall of machine shell is fixed, and the fixed fan blade of the rotary shaft at double end motor both ends, axial flow blower lower end sets heap high trestle, the heap
High trestle divides into pedestal, and the air intake connection of axial flow blower sets the suspended hood of wide-mouth air-inlet cavity, the outlet air end connection of axial flow blower
Outlet housing, the outlet air are provide with the pressurization wind chamber that diameter is gradually reduced to air outlet.
Further setting, the wide-mouth air-inlet cavity of the suspended hood are that angle is horn-like greater than 120 °.
The beneficial effects of the utility model are: the utility model air inlet is wide, after capable of quickly sucking the smog of large area
It is sent out after the pressurization of the outlet housing of taper, substantially increases suction and the discharge efficiency of smog, be suitable for fire-fighting evacuation in floor
Smog and the peace and quiet smog application of discharge.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model,
Fig. 2 is the air inlet/outlet direction schematic diagram of Fig. 1.
In figure: axial flow blower 1, fan blade 102, connecting bracket 103, blower housing 104, outlet housing 2, increases double end motor 101
Press wind chamber 201, air outlet 202, suspended hood 3, wide-mouth air-inlet cavity 301, heap high trestle 4, pedestal 5.
Specific embodiment
The technical solutions of the present invention will be further described as shown in Figure 1:, a kind of fire-fighting high-temperature smoke discharging wind
Machine, including axial flow blower 1, outlet housing 2, suspended hood 3, heap high trestle 4, pedestal 5 set double end motor in the axial flow blower 1
101, the 101 external application connecting bracket 103 of double end motor is fixed in the inner wall of blower housing 104, the rotation at 101 both ends of double end motor
The fixed fan blade 102 of shaft, is twice pressurized sucking smog, conducive to the suction for improving smog and effect is pushed, under axial flow blower 1
End sets heap high trestle 4, and the heap high trestle 4 divides into pedestal 5, and the air intake connection of axial flow blower 1 sets the suction of wide-mouth air-inlet cavity 301
Fan housing 3, air inlet is wide, can quickly suck the smog of large area, and the outlet air end of axial flow blower 1 connects outlet housing 2, the outlet air
Cover 2 sets the pressurization wind chamber 201 that diameter is gradually reduced to air outlet 202, and the smog of fixed space send out after gradually compressing
Outside improves the air pressure of smoke evacuation, and the farther, faster of smog push, the utility model air inlet is wide, can quickly suck larger
It is sent out after the pressurization of the outlet housing of taper after the smog in region, substantially increases suction and the discharge efficiency of smog, be suitable for building
Fire-fighting evacuation smog and the peace and quiet smog application of discharge in layer.
The wide-mouth air-inlet cavity 301 of the suspended hood 3 is that angle is horn-like greater than 120 °, conducive to the pumping for expanding axial flow blower
Inhale area.
Case study on implementation
It is as shown in Figure 2: after axial flow blower 1 operates, to drive wind direction consistent fan blade 102 in both ends to rotate, the smog in floor
From wide-mouth air-inlet cavity 301 axial flow blower 1 suction carry out primary compression pressurization after suck axial flow blower 1 in, also favorably and its
The smog in its region can collect to wide-mouth air-inlet cavity 301 at faster speed, and the fan blade 102 of two pieces rotation sucks axial flow blower
Push is as in outlet housing 2 after smog in 1 carries out secondary compression pressurization, and 2 interior diameter of outlet housing is gradually to the diminution of air outlet 202
Smog is carried out third level compression pressurization by the pressurization wind chamber 201 for forming taper, after sent out from outlet, fire control smoke exhausting effect is significantly high
In conventional blower.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
