Abstract
The utility model relates to a forced draft fan and provides an auxiliary mechanical device through which air and solid are of two-dimensional separation. The forced draft fan comprises a shell, an end cover, a vane wheel and a transmission shaft, wherein the vane wheel is installed on the transmission shaft, the transmission shaft is placed in the center of the shell, and the end cover is covered outside the vane wheel to seal the shell. The vane wheel comprises a fixing vane wheel mechanism fixed on the transmission shaft and a movable vane wheel mechanism fixed on the fixing vane wheel mechanism. The fixing vane wheel mechanism is a plurality of fixing vane plates fixed on a center transmission shaft. The movable vane wheel mechanism comprises a sealing plate, a vane plate and a movable vane plate shaft, wherein the sealing plate, the vane plate and the movable vane plate shaft are of one-to-one correspondence with the fixing vane plates and are sequentially fixed on each fixing vane plate. The forced draft fan is simple in workmanship, convenient to use. The special vane wheel mechanism can keep sealing effect of zero air voids between the vane wheel and the shell all the time, when a big hard lump passes through, the forced draft fan can not be clamped, and therefore the forced draft fan can be protected to normally operate and service life of the forced draft fan is prolonged.

The technical matters that the utility model solves realizes by the following technical solutions:
Blowing stopper, comprise housing, end cap, impeller and transmission shaft, wherein impeller is installed on the transmission shaft, transmission shaft is arranged on the center in the housing, end cap covers at impeller outer, with housings close, described impeller comprises the fixedly blade wheel structure that is fixed on the transmission shaft and is fixed on active impeller structure on the fixing impeller, fixedly blade wheel structure be some fixedly impeller be fixed on the center driving axle, the active impeller structure comprises and is fixed on the fixedly active leave board axle of impeller outer rim, be fixed on the active leave board on the active leave board axle, be fixed on the closing plate on the active leave board, described closing plate, active leave board, the active leave board axle is with fixedly impeller is corresponding one by one, sequentially is fastened on each fixedly on the impeller.
In the utility model; described end cap is fixed on the housing by bolt of cover, and its center is provided with bearing, and bearing plays and is the spacing effect of transmission shaft; described bearing is provided with bearing gland outward, and bearing gland is bolted on the end cap by bearing gland bearing is protected.
In the utility model, be provided with spring on the described fixedly impeller, spring one end is fixed on the fixedly outer rim of impeller, the other end is fixed on the active leave board axle with adjusting bolt by regulating sleeve, torsion is according to actual needs fixed with adjusting bolt after with regulating sleeve spring being adjusted to certain torsion.
Beneficial effect: the utility model technique is simple; easy to use, distinctive blade wheel structure can remain the zero air void sealing effectiveness between impeller and the housing, when have larger lump by the time stuck phenomenon can not occur; the normal operation of protection Blowing stopper improves its service life.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the A-A section-drawing of the utility model preferred embodiment.
Among the figure: housing 1, end cap 2, closing plate 3, active leave board 4, active leave board axle 5, fixedly impeller 6, transmission shaft 7, bearing gland 8, bearing gland bolt 9, bearing 10, bolt of cover 11, spring 12, regulating sleeve 13, adjusting bolt 14.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1,2 Blowing stopper, comprise housing 1, end cap 2, impeller and transmission shaft 7, wherein impeller is installed on the transmission shaft 7, transmission shaft 7 is arranged on the center in the housing 1, end cap 2 covers at impeller outer, with housing 1 sealing, described impeller comprises the fixedly blade wheel structure that is fixed on the transmission shaft 7 and is fixed on active impeller structure on the fixing impeller, fixedly blade wheel structure be five fixedly impeller 6 be fixed on the center driving axle 7, the active impeller structure comprises and is fixed on the fixedly active leave board axle 5 of impeller 6 outer rims, be fixed on the active leave board 4 on the active leave board axle 5, be fixed on the closing plate 3 on the active leave board 4; Described end cap 2 is fixed on the housing 1 by bolt of cover 11, and its center is provided with bearing 10, is provided with bearing gland 8 outside the described bearing 10, and bearing gland 8 is fixed on the end cap 2 by bearing gland bolt 9; Be provided with spring 12 on the described fixedly impeller 6, spring 12 1 ends are fixed on the fixedly outer rim of impeller 6, and the other end is fixed on the active leave board axle 5 by regulating sleeve 13 usefulness adjusting bolts 14.
Blowing stopper described in the utility model is when work, under the normal condition of service, driven by motor transmission shaft 7 and fixedly impeller 6 along left-hand revolution, active leave board axle 5 and active leave board 4 are with fixedly impeller 6 rotations, under the twisting force of spring 12, closing plate 3 on the active leave board 4 tightly leans against the inwall of housing 1, form the sealing state of a Zero clearance, during closing plate 3 wearing and tearing, under the twisting force of spring 12, active leave board 4 also can the auto-compensation abrasion loss, makes the sealing state that can remain the Zero clearance between closing plate 3 and housing 1 inwall;
