Abstract
The utility model discloses a kind of slurry pump impeller, including：Impeller hub；Described impeller hub is provided with multiple blades spaced apart；Described blade is curved, and described blade is fixing along position ring edge along the ring of described impeller hub, and extends to outside described impeller hub；Several protuberances are provided with described blade, described protuberance is integrally formed with described blade；Described blade leaf margin is in ripple shape or serrulate.This utility model passes through to arrange some protuberances on blade, blade leaf margin is in ripple shape or serrulate, thus increasing pump chamber space so that completely clog-free at medium inlet, and the power free of losses conveying is such that it is able to effectively prevent the big filter medium clogging pump chamber of toughness.
Description
Technical field
This utility model is related to Pulp pump field, more particularly, to a kind of slurry pump impeller.
Background technology
The media particle of Pulp pump conveying is larger, and medium composition is complicated, and therefore the anti-wear performance of pump chamber inner body is primary Consideration.The wearability of common Pulp pump has reached requirement, but in the case that medium toughness is strong, pumped (conveying) medium can precipitate condensation, and leading to the flow passage components in pump chamber to block cannot rotate, and be easily caused damage when starting shooting again.Analyzing its basic reason is：For the medium that toughness is larger, the basic reason of its blocking pump chamber is that the conveying space of Pulp pump self pump intracavity is excessively compact.
Utility model content
In view of this, this utility model provides a kind of slurry pump impeller, ensure that the conveying space of pump chamber, effectively prevents the filter medium clogging pump chamber that toughness is larger.
The technical solution of the utility model is realized in：
A kind of slurry pump impeller, including：
Impeller hub；
Described impeller hub is provided with multiple blades spaced apart；Described blade is curved, and described blade is fixing along position ring edge along the ring of described impeller hub, and extends to outside described impeller hub；
Several protuberances are provided with described blade, described protuberance is integrally formed with described blade；
Described blade leaf margin is in ripple shape or serrulate.
Preferably, the quantity of described blade is 3～6.
Preferably, the material of described blade 2 is the aluminium alloy after Surface hardening treatment.
Preferably, the material of described impeller hub is mild steel.
Preferably, described protuberance is circular protrusions.
The beneficial effects of the utility model are：
The slurry pump impeller that this utility model provides, by some protuberances are arranged on blade, blade leaf margin is in ripple shape or serrulate, thus increasing pump chamber space, make completely clog-free at medium inlet, and the power free of losses conveying is such that it is able to effectively prevent the big filter medium clogging pump chamber of toughness.
Brief description
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing of required use in embodiment or description of the prior art will be briefly described below, apparently, drawings in the following description are only some embodiments of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, can also obtain other accompanying drawings according to these accompanying drawings.
Fig. 1 is the structural representation of this utility model slurry pump impeller；
Fig. 2 is A-A sectional view in Fig. 1.
In figure：
1st, impeller hub；2nd, blade；3rd, protuberance.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into the scope of this utility model protection.
As shown in figure 1, the slurry pump impeller that this utility model provides, including：Impeller hub 1；Impeller hub 1 is provided with multiple blades 2 spaced apart；Blade 2 is curved, and blade 2 is fixing along position ring edge along the ring of impeller hub 1, and extends to outside impeller hub 1；Several protuberances 3 are provided with blade 2, protuberance 3 is integrally formed with blade 2；Blade 2 leaf margin is in ripple shape or serrulate.
In technique scheme, by arranging some protuberances 3 on blade 2, blade 2 leaf margin is in ripple shape or serrulate, thus increasing pump chamber space, make completely clog-free at medium inlet, and the power free of losses conveying is such that it is able to effectively prevent the big filter medium clogging pump chamber of toughness.
In the present embodiment, when the quantity of blade 2 is 3～6, pump chamber space can be effectively increased.
In the present embodiment, in order to improve blade 2 intensity, it is to avoid when medium viscosity is big, there is the technical problem of fracture in blade 2, the material of blade 2 is the aluminium alloy after Surface hardening treatment.
In the present embodiment, impeller hub 1 is low-carbon steel material, and its quenching hardness is low, has good machining property, and the percent thermal shrinkage of material is close with blade 2, is not likely to produce spalling.
In the present embodiment, in order to improve the intensity of blade 2, protuberance 3 is circular protrusions.
The slurry pump impeller that this utility model provides, structure is simple, reasonable in design, the pump chamber space making Pulp pump greatly increases than former space, completely clog-free at medium inlet, the power free of losses of conveying is so that the miscellaneous part of Pulp pump is constant and is applied on more complicated viscous medium transport platform position, achieve a tractor serves several purposes, save user cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all of the present utility model spirit and principle within, any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.
