Abstract
The utility model relates to a fan, in particular to a detachable impeller blade structure of a fan. The detachable impeller blade structure of the fan can prolong service life of the impeller blade of the fan and comprises an impeller blade (2), and a wear-resisting plate (1) used for protecting the impeller blade (2) is arranged on the impeller blade (2). The wear-resisting plate (1) is connected with the impeller blade (2) in a detachable mode. A wear-resisting layer used for protecting the wear-resisting plate (1) is arranged on the wear-resisting plate (1). According to the detachable impeller blade structure of the fan, the impeller blade (2) is effectively protected, and service life of the impeller blade (2) is prolonged, so that the impeller blade (2) is enabled to be wear-resisting. After the wear-resisting plate (1) is damaged, only the wear-resisting plate is needed to be detached and replaced by a new wear-resisting plate, the whole impeller blade is not needed to be changed, and therefore cost is greatly saved.
Description
Technical field
The utility model relates to a kind of blower fan, specifically the detachable impeller blade design of a kind of blower fan.
Background technique
Impeller is the critical piece of blower fan, and its geometrical shape, size, impeller blade number and accuracy of manufacturing have a significant impact performance.Impeller rotates reposefully through static balancing or dynamic balance calibration guarantee ventilator.Press the difference of impeller blade Way out, impeller be divided into forward direction, radially with backward three kinds of patterns.Forward direction impeller blade top tilts to the vane rotary direction; The vane tip of radial impeller is radially, divides again prismatic blade formula and curved blade; The vane tip of backward impeller is to the reversed dip of vane rotary.The blade shape of Centrifugal Fan Impeller is divided into again single panel type, circular arc type and wing blade etc., some impeller blade has good air dynamic behaviour, efficient is high, intensity is good, rigidity is large, in order to make the impeller blade surface suitable velocity distribution is arranged, and generally adopts the circular impeller blade.Impeller has shrouding disc usually, with the intensity of increase impeller and the Leakage Gas between minimizing impeller blade and casing, impeller blade adopts welding with connecting of shrouding disc, and the impeller blade of welding is usually non-dismountable, in case after the impeller blade wearing and tearing, whole blower fan just loses use value.
In impeller blade commonly used, during fan operation, namely when the high gas of conveying dust concentration, impeller blade weares and teares easily, long-term wearing and tearing can cause impeller blade to be worn through, and after impeller blade was worn through, impurity entered impeller blade inside, make the impeller disequilibrium and produce vibration, like this so that behind the bladed disk vibration aging speed very fast, just shorten the working life of impeller, generally only has about five months, if change whole impeller blade, expense is very expensive.
The model utility content
The technical problems to be solved in the utility model provides a kind of longer service life, the detachable impeller blade design of the better blower fan of Economy.
For solving the problems of the technologies described above, the detachable impeller blade design of the blower fan of the technical solution of the utility model comprises impeller blade, is provided with wearing plate at impeller blade, is between wearing plate and the impeller blade detachable the connection to be provided with wearing layer at wearing plate.
As shown from the above technical solution: owing at wearing plate wearing layer is arranged; between impeller blade and wearing plate, be provided with screw, nut; between impeller blade and the wearing plate by this screw and nut is detachable is connected; be provided with packing ring between impeller blade and the nut; so protected better screw; prevented that the screw rear impeller blade that is worn is connected loosening or comes off with wearing plate; and wearing plate is not easy wearing and tearing; and after the wearing plate wearing and tearing; again changing new wearing plate gets final product; need not change whole impeller sets, greatly save cost.
The detachable impeller blade design of the blower fan of the technical solution of the utility model; when the high gas of when operation input dust concentration; because being provided with wearing plate, wearing plate at impeller blade is provided with between wearing layer, wearing plate and the impeller blade and is detachable the connection; so just effectively protected impeller blade; prolonged the working life of impeller blade; not only make impeller blade wear-resisting, and detachable replacing the after the impeller blade wearing and tearing, cost greatly saved.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structure of the detachable impeller blade of blower fan of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of blower fan structure that removably connects; as shown in Figure 1, comprising impeller blade 2, be provided with the wearing plate 1 of protection impeller blade 2 at impeller blade 2; be detachable the connection between wearing plate 1 and the impeller blade 2, be provided with the wearing layer 3 of protection wearing plate 1 at wearing plate 1.As a kind of selectivity embodiment of the present utility model, this wearing layer 3 can be formed by the wear resistance electrode built-up welding.
As a kind of specific embodiment of the present utility model, be provided with screw 4, nut 5 between described wearing plate 1 and the impeller blade 2, between impeller blade 2 and the wearing plate 1 by this screw 4 and 5 detachable connections of nut.Further, between nut 5 and impeller blade 2, also be provided with packing ring 6, between impeller blade 2 and the nut 5, can play certain protective action to nut 5, make whole connection more stable.
The detachable impeller blade design of the blower fan of the technical solution of the utility model; when operation; during the high gas of input dust concentration; because be provided with wearing plate 1 at impeller blade 2, wearing plate 1 is provided with between wearing layer 3, wearing plate 3 and the impeller blade 2 as removably connecting; so just effectively protected impeller blade 2; prolonged the working life of impeller blade 2; make impeller blade 2 more wear-resisting; after wearing plate 1 damages; only need disassemble and change a new wearing plate; and need not change whole impeller blade 2, greatly saved cost.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
