Abstract
The utility model discloses a dredge pump impeller with sub-blades. The dredge pump impeller comprises an annular upper blade baseplate, and a disc-like lower blade baseplate, wherein a drive sleeve is arranged in the center of the lower blade baseplate; a blade array consisting of arc-shaped blades is arranged between the upper blade baseplate and the lower blade baseplate; a sub-blade array consisting of arc-shaped sub-blades is arranged in the circumferential direction on the upper surface of the upper blade baseplate. The dredge pump impeller provided by the utility model is improved by substituting the sub-blades on the upper blade baseplate for the conventional front water-feeding sand removing device, can directly deliver mud into pipes so as to avoid the need of a water pump set for feeding water, and can also improve pumping concentration of a dredge pump. Therefore, the dredge pump impeller has the advantages of simple structure, obvious effect and high practicability.
Description
Technical field
The utility model relates to a kind of mud pump device, or rather, is a kind of dredging pump impeller with back blades.
Background technique
Dredge pump is that one is specifically designed to carry and contains larger solid particle, such as the extracting device of the media such as silt, ore pulp, coal slurry, sandstone, comparatively extensive in sludge disposal, the field application such as dredge peculiar to vessel.The impeller of existing dredge pump is provided with front-flushing sand flushing device, need to be equipped with special water pump group, and complexity is installed, and cost is also higher.
Model utility content
The utility model is mainly to solve the existing technical problem of prior art, thereby a kind of dredging pump impeller with back blades is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of dredging pump impeller with back blades, the upper blade substrate that the described dredging pump impeller with back blades comprises an annular and a discoid lower blade substrate, the center of described lower blade substrate is provided with a drive spool, between described upper blade substrate and lower blade substrate, be provided with the array of vanes being made up of the blade of arc, the week on the upper surface of described upper blade substrate is upwards provided with the back blades array being made up of the back blades of arc.
As the utility model preferred embodiment, described back blades and upper blade substrate are that cast iron is one-body molded.
As the utility model preferred embodiment, described upper blade substrate and lower blade substrate are welded to connect with described blade respectively.
As the utility model preferred embodiment, described upper blade substrate, lower blade substrate and blade are that cast iron is one-body molded.
Dredging pump impeller with back blades of the present utility model is changed on upper blade substrate back blades is set by existing front-flushing sand flushing device, directly silt is sent in pipeline, save a water pump group that is specifically designed to bath, also increased the concentration of pumping of dredge pump simultaneously, simple in structure, successful, practical.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
As shown in Figures 1 to 5, the upper blade substrate 2 that dredging pump impeller 1 with back blades of the present utility model comprises an annular and a discoid lower blade substrate 3, the center of this lower blade substrate 3 is provided with a drive spool 5, between this upper blade substrate 2 and lower blade substrate 3, be provided with the array of vanes being formed by the blade 4 of arc, be upwards provided with the back blades array being formed by the back blades 6 of arc the week on the upper surface of this upper blade substrate 2.
This back blades 6 and upper blade substrate 2 are that cast iron is one-body molded.
This upper blade substrate 2 and lower blade substrate 3 are welded to connect with this blade 4 respectively.
This upper blade substrate 2, lower blade substrate 3 and blade 4 are that cast iron is one-body molded.
The dredging pump impeller with back blades of this model utility is changed on upper blade substrate back blades is set by existing front-flushing sand flushing device, directly silt is sent in pipeline, save a water pump group that is specifically designed to bath, also increased the concentration of pumping of dredge pump simultaneously, simple in structure, successful, practical.
Be not limited to this, any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
