The efficient energy-saving single-stage high-speed centrifugal blower is characterized by further comprising outlet guide vanes and an outlet guide vane regulating mechanism. The plurality of outlet guide vanes are installed in corresponding shaft holes on high-speed shaft end flanges of the high-speed gear box and evenly distributed in the radial direction, and the outlet guide vane regulating mechanism is connected to a shaft of the outlet guide vanes. The efficient energy-saving single-stage high-speed centrifugal blower is compact and reasonable in structure. The impeller adopts a fully-three-dimensional structure provided with main blades and secondary blades and is made of aluminum alloy with small mass so that efficiency is further improved. Meanwhile, the inlet guide vanes and the outlet guide vanes are regulated so that a wider flow regulating range can be obtained, and on the condition of continuous regulation within a range of 40% to 100% of metered flow, high efficiency can still be maintained so as to meet flow requirements under different working conditions and achieve an all-around energy saving purpose.

Description

High-efficiency and energy-saving type single-stage high-speed centrifugal blower
Technical field
The utility model relates to a kind of high-efficiency and energy-saving type single-stage high-speed centrifugal blower; Specifically after improving on the basis of single-stage high-speed centrifugal blower, have more a kind of energy-saving blower of high efficiency and wideer flow adjustment range, belong to the mechanical structure technical field.
Background technique
At present; The major technique that is used for the homemade single-stage high-speed centrifugal blower in the aeration in sewage treatment system comes from the technology of introducing advanced country's the eighties; The impeller that uses on this series products is not full 3 d impeller; Impeller has only primary blades not divide blade, and energy loss is relatively large, and efficient is on the low side; Simultaneously, it is adjustable that this series products has only inlet guide vane, and exit guide blade is fixed, and flow adjustment range generally is the 70%-100% of rated flow, can not satisfy under the different operating modes the requirement of flow, is difficult to the energy-saving effect that reaches desirable.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, thereby a kind of high-efficiency and energy-saving type single-stage high-speed centrifugal blower is provided, and it has more high efficiency, and can be in the 40%-100% of rated flow scope regulated at will.
The scheme that provides according to the utility model; High-efficiency and energy-saving type single-stage high-speed centrifugal blower comprises high-speed gear box, spiral case, impeller, air intake body, inlet guide vane and inlet guide vane controlling mechanism; Said spiral case is installed on the flange of high speed axle head of high-speed gear box; Said impeller is through on the high speed shaft that is bolted to high-speed gear box, and said air intake body is installed in the air intake of spiral case, and said several inlet guide vanes are installed in the radially axis hole of air intake of spiral case; And radially being the state of being uniformly distributed with, the inlet guide vane controlling mechanism is connected on the axle of inlet guide vane; Characteristic is: also comprise exit guide blade and exit guide blade controlling mechanism; Said several exit guide blades are installed in the corresponding axis hole on the high speed shaft end flange of high-speed gear box; And radially being the state of being uniformly distributed with, the exit guide blade controlling mechanism is connected on the axle of exit guide blade.
As further improvement of the present invention, said impeller is provided with 6-12 primary blades, is provided with a branch blade in the middle of every two adjacent primary blades.
As further improvement of the present invention, said impeller is processed by aluminum alloy.
As further improvement of the present invention, said exit guide blade is generally 9-19, and can regulate.
Compared with present technology the utility model has the following advantages:
The utility model compact structure, reasonable; Impeller adopts has primary blades and the full ternary structural that divides blade, and is processed by the little aluminum alloy of quality, and efficient is further enhanced.Regulating inlet guide vane and exit guide blade simultaneously can make and the utlity model has wideer flow adjustment range; Adjusting still can keep higher efficient continuously in the 40%-100% of rated flow scope; To adapt to the traffic demand under the different operating modes, reach comprehensive purpose of energy saving.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Following the utility model will combine accompanying drawing to further describe:
As shown in Figure 1: as to comprise high-speed gear box 1, spiral case 2, impeller 3, bolt 4, air intake body 5, inlet guide vane 6, inlet guide vane controlling mechanism 7, exit guide blade 8 and exit guide blade controlling mechanism 9 etc.
Said spiral case 2 is installed on the flange of high speed axle head of high-speed gear box 1; Said impeller 3 is fixed on the high speed shaft of high-speed gear box 1 through bolt 4; Said air intake body 5 is installed in the air intake of spiral case 2; Said several inlet guide vanes 6 (be generally 11-19) are installed in the radially axis hole of air intake of spiral case 2, and radially are being the state of being uniformly distributed with, and inlet guide vane controlling mechanism 7 is connected on the axle of inlet guide vane 6; Said several exit guide blades 8 (be generally 9-19) are installed in the corresponding axis hole on the high speed shaft end flange of high-speed gear box 1, and radially are being the state of being uniformly distributed with, and are to regulate.Exit guide blade controlling mechanism 9 is connected on the axle of exit guide blade 8.
Said inlet guide vane controlling mechanism 7 and exit guide blade controlling mechanism 9 structures are identical, and it has applied for patent of invention, and name is called diffusion guide vane synchronous adjusting mechanism of high-speed centrifugal fan, patent No. ZL200910222568.7.It mainly is made up of rotating disk, pivoted arm, axle sleeve; Pivoted arm and guide vane teunnion are fixedly connected, and form revolute pair with axle sleeve, and the sliding-groove on axle sleeve and the rotating disk forms sliding pair; When dial rotation; Axle sleeve slides in the rotating disk sliding-groove, makes pivoted arm around the guide vane teunnion rotational, thereby realizes the adjusting to stator.
Said impeller 3 is provided with several (being generally 6-12) primary blades, is provided with a branch blade in the middle of every two adjacent primary blades.Said impeller 3 is processed by aluminum alloy.
When impeller 3 is made high-speed rotation with the high speed shaft of high-speed gear box 1; Air flows in the impeller cavity 3-1 behind the inner chamber of arrow A direction entering air intake body 5 among Fig. 1, and air flows to the impeller outlet direction under the centrifugal action of impeller 3, and receives the diffusion action of impeller; Pressure ability and kinetic energy all are improved; Air is through the further effect of exit guide blade 8 then, and kinetic energy further is converted into the pressure ability again, and final air gets in the spiral case runner 2-1; And will have the air of certain pressure and draw outside the machine through the outlet (figure is last not to be drawn) of spiral case 2, get into air conduit.Because impeller 3 has adopted the aluminum alloy impeller with primary blades and the full ternary structural that divides blade, and exit guide blade 8 can make the air flow resistance minimum through regulating, so have the pneumatic efficiency higher than prior art.When operating mode changes when need changing flow,, can make the utility model in the 40%-100% of rated flow scope, connect adjusting and still can keep higher efficient, thereby reach comprehensive purpose of energy saving through regulating inlet guide vane 6 and exit guide blade 8.
