Description
Technical field
The utility model relates to chemical industry, metal smelt field.Be applicable to a kind of diffuser vane controlling mechanism on high pressure centrifugal blower.
Background technique
Along with the development of national economy, energy-conserving and environment-protective become main flow.Under existing technological accumulation and inheritance, its efficiency of high speed and high pressure centrifugal blower is generally 65 ~ 73%, it cannot reach energy-conservation effect, main cause is that the gas shock in its blower fan runner causes a large amount of energy loss, impeller outlet air-flow is through Diffuser, the blade of Diffuser does not mate with flow angle, causes fan efficiency greatly to reduce.
Model utility content
The utility model is intended to overcome above-mentioned defect, and object is to provide the high-speed centrifugal blower diffuser vane controlling mechanism that a kind of Torque-adjusting is little, adjustment efficiency is high, go slick.
For achieving the above object, the technical solution adopted in the utility model is: be made up of control ring, support pulley, Diffuser back side panel, transmission group, blade, Diffuser front side plate; It is characterized in that blades installation is between Diffuser back side panel and Diffuser front side plate, each blade is provided with slide bar, central minor axis, central longitudinal axis, and Diffuser back side panel, Diffuser front side plate are all provided with curve bath, axis hole on pipes' analysis; Transmission group is made up of drive link and transmission handle, and transmission group and blade are fixed by keyway, and nut check connects; Supporting pulley circumference uniform distribution is arranged on Diffuser back side panel, be buckled in by control ring and support on pulley, control ring is provided with U-type groove, initiatively handle, and drive link and U-type groove answer one_to_one corresponding to install, slide bar inserts curve bath, and central minor axis, central longitudinal axis are installed in axis hole.
Owing to adopting technique scheme, make high speed and high pressure centrifugal blower efficiency improve 5 ~ 10%, greatly reduce the energy consumption of blower fan, its flexible adjustment, without stuck phenomenon, plays good guide functions to the air-flow of impeller outlet, decrease gas shock loss, improve the overall efficiency of blower fan.

Embodiment
Below in conjunction with accompanying drawing, explanation is described further to the utility model.
A kind of high-speed centrifugal blower diffuser vane controlling mechanism, it is made up of control ring (1), support pulley (2), Diffuser back side panel (3), transmission group (6), blade (4), Diffuser front side plate (5); Blade (4) is installed between Diffuser back side panel (3) and Diffuser front side plate (5), transmission group (6) and blade (4) are fixed by keyway, nut check connects, supporting pulley (2) circumference uniform distribution is arranged on Diffuser back side panel (3), is buckled in by control ring (1) and supports on pulley (2).It regulates efficiency high, greatly reduces the energy consumption of blower fan; Good guide functions is played to the air-flow of impeller outlet, decreases gas shock loss, improve the overall efficiency of blower fan.
Each blade (4) of this embodiment is provided with slide bar (7), central minor axis (8), central longitudinal axis (11); Diffuser back side panel (3), Diffuser front side plate (5) are all provided with curve bath (12), axis hole (13) on pipes' analysis; Slide bar (7) inserts curve bath (12), and central minor axis (8), central longitudinal axis (11) are installed in axis hole (13).Adopt this structure driven effect very good, very flexibly, its transmission resistance produced is little; By curve bath (12), blade rotation angular range is limited, better ensure the operating spacing and stability of blade.
The transmission group (6) of this embodiment is made up of drive link (9) and transmission handle (10); Control ring (1) is provided with U-type groove (14), initiatively handle (15); Drive link (9) and U-type groove (14) answer one_to_one corresponding to install.Adopt each vane belt stress equalization of its adjustment doors of this scheme, pull adjusting vane angle by the upper initiatively handle (15) of control ring (1), well meet the adjustment of blower fan in performance, make the loss on air-flow reduce to minimum.
Therefore, the utility model be a kind of Torque-adjusting little, regulate that efficiency is high, the centrifugal blower diffuser vane controlling mechanism that goes slick.
