Abstract
The utility model relates to a device for sand-suction pump, specifically a sand-stirring device for sand-suction pump comprising a hollow mandrel which is connected with a pump shaft, wherein the front end of the hollow mandrel has conical degree; a set of short vanes, a set of medium long vanes and a set of long vanes are arranged on the hollow mandrel; each set of vans is respectively uniformly distributed on the same circumference; the vans have variable cross-section structure along their radius direction. In the technical scheme employed in the utility model, the hollow mandrel is directly connected with the pump shaft, the three sets of vanes work together to stir the sand and the pump collects the stirred sand during sand-suction operation, which is different from the prior art. The utility model is simple in structure, uniform in stir and light in weight, furthermore the power consumption of the auxiliary devices is saved.
Description
Technical field:
The utility model relates to a kind of sand suction pump device, and a kind of specifically sand suction pump is with stirring husky device.
Background technology:
At present sand suction pump stirs silt and adopts mostly and be equipped with a water under high pressure pipeline or other forms near silt is on every side washed away stirring.There is system complex in this class formation, stirs uneven, shortcomings such as efficient is low, fault rate height.
The utility model content:
Goal of the invention of the present utility model is to overcome the deficiency of background technology and provides a kind of sand suction pump of not outer configuration high-pressure water pipe or other mixing plants that need not with stirring husky device.
The utility model adopts following technical scheme:
A kind of sand suction pump is with stirring husky device, comprise the hollow mandrel that is connected with pump shaft, described hollow mandrel front end has tapering, and weak point, middle length and long three groups of blades are housed respectively on this hollow mandrel, described every group of blade is distributed in respectively on the same circumference, and described blade prolongs its radial direction and is variable section structure.
The utility model of employing technique scheme compared with prior art, the hollow mandrel directly links to each other with pump shaft, when inhaling husky operation under the acting in conjunction of three groups of blades, silt is stirred the suction pump housing, the utlity model has simple in structure, stir, in light weight, the advantage of saving servicing unit and power consumption.
As a kind of preferred version of the present utility model, described weak point, middle length and long three groups of blades by hollow mandrel front end to pump shaft link axial arranging successively.
As a kind of preferred version of the present utility model, described every group of blade quantity is three, is 120 ° and is distributed on the same circumference.
As a kind of preferred version of the present utility model, the variable section structure of described blade is to reduce gradually to the elongated end cross section with hollow mandrel link.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the lateral view of Fig. 1.
The specific embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
A kind of sand suction pump is with stirring husky device, referring to accompanying drawing 1, among the figure: hollow mandrel 1, connecting rod 2, short blade 3, middle linear leaf 4, pump shaft 5, linear leaf 6.
In the present embodiment, pump shaft 5 connects hollow mandrel 1 by connecting rod 2, hollow mandrel 1 front end has tapering, short blade 3, middle linear leaf 4 and linear leaf 6 are housed respectively on the hollow mandrel 1, every group of blade is distributed in respectively on the same circumference, that is: short blade 3 is distributed on the same circumference, and middle linear leaf 4 equal Burundis are on same circumference, and linear leaf 6 is distributed on the same circumference; Short blade 3, middle linear leaf 4 and linear leaf 6 all be prolong its separately radial direction be variable section structure.
As a kind of preferred structure of present embodiment, short blade 3, middle linear leaf 4 and linear leaf 6 be by hollow mandrel 1 front end to the pump shaft 5 links form of structure of axial arranging successively.
As a kind of preferred structure of present embodiment, every group of blade quantity is three, is 120 ° and is distributed on the same circumference; That is: the quantity of short blade 3 is three, is distributed on the same circumference; The quantity of middle linear leaf 4 is three also, is distributed on the same circumference; The quantity of linear leaf 6 is three also, is distributed on the same circumference.
As a kind of preferred structure of the present utility model, become in every group of blade and cut and structure all is to be with hollow mandrel 1 link to reduce gradually to the elongated end cross section.
Short blade 3 in the present embodiment, middle linear leaf 4 and linear leaf 6 be by hollow mandrel 1 front end to the pump shaft 5 links form of structure of axial arranging successively, wherein the axial spacing between short blade 3, middle linear leaf 4 and linear leaf 6 threes can be for equidistantly.
The utility model is not limited to the cited form of structure of the foregoing description, and the quantity of every group of blade also can be four or other quantity, also is uniform state setting; All be considered as within protection domain of the present utility model.
In the present embodiment, hollow mandrel 1 directly links to each other with pump shaft 5, under the acting in conjunction of three groups of blades, silt is stirred the suction pump housing when inhaling husky operation, the utlity model has simple in structure, stir, in light weight, the advantage of saving servicing unit and power consumption.
