The utility model is achieved in that a kind of air-curtain used in mine rectifier, and described rectifier one end cross-sectional is circular, and cross section, the other end is rectangle, and between two ends, outline line adopts bicubic side's curve model; Baffle is provided with in described rectifier.
Preferably, described baffle is made up of Part I and Part II, and wherein, a lateral section of Part I is circular, and to be positioned at rectifier end cross section be circular side, and described Part I is ellipse with the opposite side cross section of its circular cross-section relatively;
Described Part II is cone, and the bottom surface of this cone is identical with the elliptic cross-section of Part I and dock, and this cone is summit relative to side, bottom surface, and this summit is positioned at side, rectifier square-section;
Described baffle and the coaxial heart of rectifier.
Compared to the shortcoming and defect of prior art, the utility model has following beneficial effect: the utility model adopts bicubic side's curve model design rectifier profile, effectively reduce drag losses and energy consumption, and rectifier length can design shorter, reduce further cost.
Accompanying drawing explanation
Fig. 1 is the front perspective structural representation after the utility model air-curtain used in mine rectifier and air feed device combine;
Fig. 2 is at Fig. 1 top perspective structural representation.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Fig. 1 ~ 2, Fig. 1 is the front perspective structural representation after the utility model air-curtain used in mine rectifier and air feed device combine; Fig. 2 is at Fig. 1 top perspective structural representation.
A kind of air-curtain used in mine rectifier, described rectifier 1 one end cross-sectional is circular, cross section, the other end is rectangle, between two ends, outline line adopts bicubic side's curve model (to refer to bibliography: Li Guowen, Xu Rangshu. Wind Tunnel Contraction curve aeroperformance research [J]. experimental fluid mechanics, 2009,23 (4): 73-76.); Be provided with baffle 2 in described rectifier, this baffle 2 is hollow obturator.
In the utility model, more specifically, described baffle 2 is made up of Part I 2-1 and Part II 2-2, wherein, one lateral section of Part I 2-1 is circular, and to be positioned at rectifier 1 end cross-sectional be circular side, described Part I 2-1 is ellipse with the opposite side cross section of the circular cross-section of Part I 2-1 relatively; Described Part II 2-2 is cone, and the bottom surface of this cone is identical with the elliptic cross-section of Part I 2-1 and dock, and this cone is summit relative to side, bottom surface, and this summit is positioned at side, rectifier 1 square-section; Described baffle 2 and the coaxial heart of rectifier 1.
In actual application of the present utility model, this air-curtain used in mine rectifier and air feed device 3 with the use of, wherein, side, rectifier 1 square-section is docked with the air intake of air feed device 3, and the axial line of rectifier 1 is crossing with the center line of air feed device 3 and form angle a.When air feed device 3 works, wind is passed by the passage between baffle 2 and rectifier 1.
The utility model adopts bicubic side curve model design rectifier profile, effectively reduces drag losses and energy consumption, and rectifier length can design shorter, reduce further cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
