Abstract
The invention relates to the technical field of fans, in particular to an ultrahigh-temperature fan impeller mounting structure. The ultrahigh-temperature fan impeller mounting structure comprises impeller sets arranged on a main shaft; each impeller set includes two impellers; the two impellers are arranged on the main shaft back to back; and intake ports of the two impellers are respectively positioned on the left and right two sides of the impeller set. The impellers in the impeller sets adopt the back-to-back mounting mode; and the axial force generated to the main shaft in rotation of the two impellers is the same in magnitude and opposite in direction, and is mutually counteracted, so that the axial acting force acted on bearings by the main shaft is eliminated, and the service life of the bearings is prolonged.
Description
Technical field
The present invention relates to blower fan technical field, particularly to a kind of superhigh temperature draught fan impeller mounting structure.
Background technology
Fan industry at home, operating temperature at 650 DEG C, pressure reach 10kPa and more than, air quantity is at 1500Nm3/ h and
The application demand of following small flow high pressure power superhigh-temperature and-pressure blower fan is increasing；But at present, domestic this superhigh temperature blower fan
The urea pyrolysis system of gas engine thermoelectricity F level unit equipment for denitrifying flue gas is applied also beyond example, and domestic current application
Gas engine thermoelectricity F level unit all use external imported technology and equipment, and the blower fan supporting with it also only has state's outgoing
Reach country can produce, cause production, maintenance cost cycle to remain high, and often maintenance cycle cannot be guaranteed.For realizing
Flue gas rises to required pressure, and existing blower fan generally uses the mode that multiple impeller pressurizes, and at the leaf of these blower fans
Using impeller on wheel mounting means more and being arranged side by side installation, blower fan main shaft can be produced by this mounting structure when impeller rotates
Raw bigger axial force, when multi-stage impeller operates simultaneously, produced axial force is then bigger, affects the stability of fan operation
And the service life of fan bearing.
Content of the invention
It is an object of the invention to solve the above-mentioned technical problem that existing draught fan impeller mounting structure is caused, one is provided
Superhigh temperature draught fan impeller mounting structure, mounting structure is simple, can effectively eliminate impeller and rotate axial force produced by main shaft, with
When can well realize the pressurization to high-temperature flue gas.
For solving above-mentioned technical problem, present invention employs a kind of superhigh temperature draught fan impeller mounting structure, including be arranged on
Impeller sets on main shaft, described impeller sets of often organizing includes two impellers, and said two impeller is arranged on main shaft back-to-back, two
Air inlet on impeller lays respectively at the left and right sides of this group impeller sets.
In technique scheme, further, described impeller sets is outside equipped with casing, is provided with left chamber in described casing
With right chamber, two impellers lay respectively in left chamber and right chamber, are provided with connection logical between described left chamber and right chamber
Road.
In technique scheme, further, described casing is respectively arranged with inlet channel and exhaust passage, a described left side
Chamber connects inlet channel, and right chamber connects exhaust passage, and described left chamber air inlet is equipped with left side impeller air inlet,
Left chamber's gas outlet connection interface channel, the right chamber inlet of interface channel connection, right chamber inlet and right side impeller air inlet
Mouth is equipped with, and right chamber exit connects exhaust passage.
Impeller in impeller sets of the present invention uses back-to-back mounting means, and main shaft is produced by two impellers when rotated
Axial force size identical, in opposite direction, both cancel out each other, thus eliminate the axial force that main shaft acts on bearing,
Extend the service life of bearing.Meanwhile, in conjunction with impeller Back-to-back installation, the left and right chamber of connection is set in casing,
While realizing that impeller two-stage is pressurizeed, it is ensured that stability in transmitting procedure for the pressure, reduce the pressure loss.

Detailed description of the invention
The present invention is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, superhigh temperature draught fan impeller mounting structure in the present embodiment, including the impeller sets being arranged on main shaft 1,
Often organize impeller sets and include two impellers, generally use in existing blower fan and use side by side, install in the same direction between two blower fans
Mode, and in the present embodiment, two impellers use setting back-to-back, and the peace contrary with existing structure on main shaft
Dress mode, now the air inlet on two impellers lays respectively at the left and right sides of this group impeller sets.
In above-described embodiment, the impeller in impeller sets uses back-to-back mounting means, and two impellers are when rotated to master
Produced by axle, axial force size is identical, in opposite direction, and both cancel out each other, thus eliminate that main shaft acts on bearing axial
Active force, extends the service life of bearing.
It such as Fig. 2, is outside equipped with casing 13 in impeller sets, in casing 13, be provided with left chamber 4 and right chamber 5, two impellers
Lay respectively in left chamber 4 and right chamber 5, between left chamber 4 and right chamber 5, be provided with interface channel 6.Set respectively on casing 13
Being equipped with inlet channel 11 and exhaust passage 12, left chamber 4 connects inlet channel 11, and right chamber 5 connects exhaust passage 12, left chamber
Air inlet 7 is equipped with left side impeller 2 air inlet, and left chamber gas outlet 8 connects interface channel 6, and interface channel 6 connects right chamber
Room air inlet 9, right chamber inlet 10 is equipped with right side impeller 3 air inlet, and right chamber exit 10 connects exhaust passage
12.
Such as Fig. 2, high-temperature flue gas enters in casing through inlet channel, through in impeller on the left of the entrance of left side impeller air inlet, left
High-temperature flue gas is pressurizeed by lateral lobe wheel, enters interface channel from left chamber gas outlet, and the high-temperature flue gas after pressurization is through lobus lateralis dexter
Impeller on the right side of wheel air inlet entrance, after right side impeller carries out secondary pressurized to high-temperature flue gas, the row of entrance after right chamber exit
