Abstract
The utility model discloses an impeller for feeding two-phase fluid of liquid and solid, comprising a rear cover plate, a rear vane, a front cover plate and a front vane. A cavity for the fluid to flow is arranged between the rear cover plate and the front cover plate; the cavity is narrower gradually from inside to outside, and under the same flow condition, the fluid flows faster and faster in the cavity from inside to outside, therefore, the utility model is beneficial to feeding fluid containing suspended substances without the occurrence of blockage.
Description
Technical field
The utility model relates to a kind of impeller that liquid-solid two-phase fluid is carried that is used for, and especially relates to the cavity body structure that flow of fluid is provided in this impeller.
Background technique
The industrial pump that is usually used in the liquid-solid two-phase fluid conveying, mainly be applicable to carry and contain SS (as concentrate, mine tailing, lime-ash, coal slime, cement, earth and sand etc.) liquid, the slurries Cmax that is transferred is 50-70% by weight, and allow by a small amount of big solid particle, the impeller of this class pump comprises back shroud and rear blade, front shroud and front vane, between back shroud and front shroud, formed a cavity that flows for liquid, conventional, the cross sectional area size of this cavity is all identical from the inside to the outside, containing under the more situation of suspended matter, be unfavorable for the conveying of fluid, when particularly having the large particle solid in the fluid, also blocking phenomenon may appear.
The model utility content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of not susceptible to plugging impeller is provided.
The purpose of this utility model is achieved in that
A kind of impeller that is exclusively used in the liquid-solid two-phase fluid conveying comprises back shroud and rear blade, front shroud and front vane, has one for the mobile cavity of fluid between back shroud and front shroud, and the cross-section area of this cavity diminishes from the inside to the outside one by one.
As improvement of the present utility model, described front shroud is streamlined corresponding to a side of cavity.
The utility model has following advantage than prior art:
Because the cavity design that the fluid that the utility model provides flows is to diminish one by one for its cross-section area from the inside to the outside, under the situation of same traffic, stream is fast more more from the inside to the outside in cavity will to make fluid, is more conducive to contain the conveying of the fluid of suspended matter, the difficult obstruction; Further, front shroud is designed to streamlined corresponding to a side of cavity, has reduced the resistance of fluid, be more conducive to flowing of fluid.
Description of drawings
Fig. 1 is a sectional view of the present utility model.Among the figure, front vane 1, rear blade 2, front shroud 3, back shroud 4 and cavity 5.
Embodiment
A kind of impeller that is exclusively used in the liquid-solid two-phase fluid conveying, comprise back shroud 4 and rear blade 2, front shroud 3 and front vane 1, between back shroud 4 and front shroud 3, have one for the mobile cavity 5 of fluid, wherein front shroud 3 is designed to streamlinedly corresponding to a side of cavity 5, and the cross-section area of this cavity 5 diminishes from the inside to the outside one by one.
Claims (2)
1, a kind of impeller that is exclusively used in the liquid-solid two-phase fluid conveying, comprise back shroud and rear blade, front shroud and front vane, between back shroud and front shroud, have one for the mobile cavity of fluid, it is characterized in that the cross-section area of this cavity diminishes from the inside to the outside one by one.
2, impeller according to claim 1 is characterized in that described front shroud is streamlined corresponding to a side of cavity.
