Abstract
The invention relates to an impeller of a heated-air circulation fan, which structurally comprises a front plate, a middle plate and a rear plate which are sequentially arranged, wherein at least ten arc short blades are respectively arranged between the front plate and the middle plate as well as between the middle plate and the rear plate, the front plate is connected with the middle plate through the short blades, the middle plate is connected with the rear plate through the short blades, at least two arc long blades are also arranged between the front plate and the rear plate and are uniformly arranged among the short blades at intervals, the two ends of the long blades are respectively fixed with the front plate and the rear plate, and the middle parts of the long blades are fixed with the middle plate. The impeller of the heated-air circulation fan has higher strength, is simple to manufacture, and can be applied in large heat treating furnaces with high wind pressure, large blast volume and high furnace temperature.
Description
Technical field
The present invention relates to the technical field of blower fan, be specifically related to a kind of impeller of hot air circulation blower.
Background technique
Impeller is one of critical piece of hot air circulation blower, can realize the agitating function of hot blast, can improve the uniformity and the thermal treatment quality of temperature in the industrial heat treatment furnace effectively, reduces fan noise and energy consumption simultaneously.The structure of the impeller of present employed hot air circulation blower comprises: the shroud that sets gradually, mid-game and hub disk; Evenly be provided with some circular arc short blades along hoop respectively between shroud and mid-game and mid-game and the hub disk; Be connected through short blade between described shroud and the mid-game, also be connected between described mid-game and the hub disk through short blade.Use the hot air circulation blower of above-mentioned impeller only to be applicable to low blast, little air quantity, hang down the small-sized heat treatment furnace of furnace temperature; When being applied to the large-scale heat treatment furnace of high blast, big air quantity, high furnace temperature; Owing to belong to indirect linkage structure between shroud and the hub disk, thereby make the intensity of impeller lower, under the impact of high blast, big air quantity, high furnace temperature; Distortion appears in impeller easily, and total head value deviation becomes big, fan efficiency reduces, fan noise becomes big thereby make.
Summary of the invention
Technical problem to be solved by this invention is: the impeller that the higher hot air circulation blower of a kind of intensity is provided.
For addressing the above problem; The technological scheme that the present invention adopts is: the impeller of hot air circulation blower, and its structure comprises: the shroud that sets gradually, mid-game and hub disk are respectively arranged with at least ten circular arc short blades between shroud and mid-game and mid-game and the hub disk; Be connected through short blade between described shroud and the mid-game; Also be connected through short blade between described mid-game and the hub disk, also be provided with at least two circular arc linear leafs between described shroud and the hub disk, described linear leaf is disposed in an evenly spaced relation between the short blade; The two ends of described linear leaf fix with shroud and hub disk respectively, and the middle part and the mid-game of linear leaf fix.
The linkage structure of described linear leaf and mid-game is: the middle part of described linear leaf is provided with draw-in groove, and described linear leaf fixes at draw-in groove place and mid-game.
Be respectively arranged with 20 ~ 28 circular arc short blades between described shroud and mid-game and mid-game and the hub disk; Evenly be provided with 6 ~ 10 circular arc linear leafs along hoop between described shroud and the hub disk; The quantity of the short blade between the adjacent linear leaf all equates, and described short blade evenly is arranged between the adjacent linear leaf along hoop.
The invention has the beneficial effects as follows: the intensity of the impeller of above-mentioned hot air circulation blower is higher, simple for production; When the hot air circulation blower that uses above-mentioned impeller is applied to the large-scale heat treatment furnace of high blast, big air quantity, high furnace temperature; Impeller can distortion not occur under the impact of high blast, big air quantity, high furnace temperature; Under rated speed, regulation air quantity, total head value deviation≤4%, fan efficiency raising 5%, fan noise lower 10% through test.

Embodiment
Through specific embodiment the impeller of hot air circulation blower of the present invention is done further to describe in detail below.
Like Fig. 1, shown in Figure 2; The impeller of hot air circulation blower of the present invention, its structure comprises: the shroud 1 that sets gradually, mid-game 2 and hub disk 3 are respectively arranged with 24 circular arc short blades 4 between shroud 1 and mid-game 2 and mid-game 2 and the hub disk 3; Be connected through short blade 4 between described shroud 1 and the mid-game 2; Also be connected through short blade 4 between described mid-game 2 and the hub disk 3, evenly be provided with 8 circular arc linear leafs 5 along hoop between described shroud 1 and the hub disk 3, per 3 short blades 4 evenly are arranged between the adjacent linear leaf 5 along hoop respectively; The two ends of described linear leaf 5 fix with shroud 1 and hub disk 3 respectively; As shown in Figure 3, the middle part of described linear leaf 5 is provided with draw-in groove 6, and described linear leaf 5 fixes through welding and mid-game 2 at draw-in groove 6 places.
Principle of the present invention is: between shroud 1 and hub disk 3, linear leaf 5 is set; And the two ends of linear leaf 5 fix with shroud 1 and hub disk 3 respectively; The middle part of linear leaf 5 and mid-game 2 fix; Make between shroud 1, mid-game 2 and the hub disk 3 of impeller and be direct linkage structure, thereby increased the intensity of impeller.
The invention has the beneficial effects as follows: the intensity of the impeller of above-mentioned hot air circulation blower is higher, simple for production; When the hot air circulation blower that uses above-mentioned impeller is applied to the large-scale heat treatment furnace of high blast, big air quantity, high furnace temperature; Impeller can distortion not occur under the impact of high blast, big air quantity, high furnace temperature; Under rated speed, regulation air quantity, total head value deviation≤4%, fan efficiency raising 5%, fan noise lower 10% through test.
