Abstract
The utility model discloses a kind of dredge pump open-type impeller, it is characterised in that：The impeller includes a circular impeller matrix and multiple blades；Radius of the length of the blade less than or equal to the impeller matrix；Height of the height of the blade more than the impeller matrix；The axis hole passed through for rotating shaft is provided with the central authorities of the impeller matrix；The plurality of blade is with the center of axis hole as basic point annular array；Region between two neighboring blade is fluid passage, and the sectional area of the fluid passage gradually broadens from axis hole center to blade edge.This utility model is rotated under the drive of motor at a high speed, the vortex of generation is conveyed with realizing medium, plus spacious runner design in unshrouded impeller and volute, so that the various solid particles in medium, even be easy to wind fiber sundries, as long as volute water sucking mouth can be entered, unimpededly can be seen off, real achieves nonclogging effect.
Description
Technical field
This utility model is related to a kind of dredge pump, more particularly to a kind of being installed in dredge pump has opening without blocking function
Open formula impeller.
Background technology
When blowdown is carried out, impeller is susceptible to block existing dredge pump, affects filth-discharging effect.
Utility model content
The purpose of this utility model is to solve the problems of the prior art, there is provided a kind of dredge pump open-type impeller.
The technical solution of the utility model is：A kind of dredge pump open-type impeller, it is characterised in that：The impeller includes one
Circular impeller matrix and multiple blades；Radius of the length of the blade less than or equal to the impeller matrix；The blade
Highly more than the height of the impeller matrix；The axis hole passed through for rotating shaft is provided with the central authorities of the impeller matrix；The plurality of
Blade is with the center of axis hole as basic point annular array；Region between two neighboring blade be fluid passage, the fluid
The sectional area of passage gradually broadens from axis hole center to blade edge.
Preferably, the outer end of the blade is inclined-plane.
Preferably, the blade is 6, and the fluid passage is 6 roads.
Preferably, the outer end thickness of the impeller matrix is more than its inner thickness.
Preferably, the blade muscle corresponding with the blade is provided with the back side of the impeller matrix.
This utility model is rotated under the drive of motor at a high speed, and the vortex of generation is conveyed with realizing medium, adds open type leaf
Spacious runner design in wheel and volute so that the various solid particles in medium, the fiber-like for being even easy to wind are miscellaneous
Thing, as long as volute water sucking mouth can be entered, unimpededly can be seen off, and real achieves nonclogging effect.
Further, since the impeller is located at the top of volute, and there is extremely spacious flow channel space in front of impeller, so
When solid particle polluter is conveyed by high turbine pump, most of granules are not actually contacted with impeller, so as to subtract significantly
Abrasion is lacked.
Description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is side view of the present utility model.
Specific embodiment
In order that technological means, technical characteristic, utility model purpose and technique effect that this utility model is realized are easy to bright
White understanding, with reference to being specifically illustrating, is expanded on further this utility model.
As depicted in figs. 1 and 2, it is a kind of dredge pump open-type impeller of the present utility model, the impeller 1 includes that one is circular
Impeller matrix 10 and six blades 11；The outer end thickness of impeller matrix 10 is more than its inner thickness.
Radius of the length of the blade 11 less than or equal to the impeller matrix 10, blade 11 is straight in the present embodiment
Line length is identical with the radius of impeller matrix 10.
Impeller is reinforced for further, six corresponding with the blade 11 piece is provided with the back side of the impeller matrix 10
Blade muscle 14, its thickness are slightly above the impeller matrix 10.
Height of the height of the blade 11 more than the impeller matrix 10；Above-mentioned impeller matrix 10, the size of blade 11
Can be configured according to pump housing size；For being venturi effect that impeller realizes high speed under the drive of rotating shaft, in the present embodiment
Blade 11 outer end be inclined-plane, be easy to quickly realize pump housing blowdown.
The central authorities of the impeller matrix 10 in the present embodiment are provided with the axis hole 12 passed through for rotating shaft, and the axis hole 12 is used for and motor
Rotating shaft be connected, rotated in the pump housing with impeller 1, form vortex.
Six blades 11 in the present embodiment are with the center of axis hole 12 as basic point annular array；In two adjacent leaves
Region between piece 11 is fluid passage 13, is formed with six road fluid passages 13 between six blades 11.
The sectional area of the fluid passage 13 gradually broadens from the center of axis hole 12 to the edge of blade 11 so that in medium
Various solid particles, be even easy to wind fiber sundries rapidly from discharge outlet discharge, blocking will not be produced.
This utility model is rotated under the drive of motor at a high speed, and the vortex of generation is conveyed with realizing medium, adds open type leaf
Spacious runner design in wheel and volute so that the various solid particles in medium, the fiber-like for being even easy to wind are miscellaneous
Thing, as long as volute water sucking mouth can be entered, unimpededly can be seen off, and real achieves nonclogging effect.
Further, since the impeller is located at the top of volute, and there is extremely spacious flow channel space in front of impeller, so
When solid particle polluter is conveyed by high turbine pump, most of granules are not actually contacted with impeller, so as to subtract significantly
Abrasion is lacked.
It is only this utility model preferred embodiment in sum, is not used for limiting practical range of the present utility model.
Equivalence changes and modification that i.e. all contents according to this utility model claim are made, should all belong to skill of the present utility model
Art category.
