Specific embodiment
With reference to specific embodiment, the present invention is further described：
As shown in Figure 1, a kind of efficiently clog-free sewage cutting pump, be equipped with including the pump housing 1, in the pump housing 1 pump shaft 2,
Cutterhead 3 and impeller 4, circumference array is equipped with two volution blades 5,2 front end of the pump shaft warp on the blade mounting surface of the impeller 4
Terminal pad 6 is fixedly connected with impeller 4, and rear end is connected with power source, and 1 center of the pump housing is equipped with water inlet 16, and side wall is equipped with
Discharge outlet 17, the inlet end of the pump housing 1 are equipped with cutterhead 3, it is characterised in that the blade mounting surface center of impeller 4 is equipped with convex
Guiding cone 7,7 periphery of convex guiding cone are equipped with arc-shaped curved surface 8, and the arc-shaped curved surface 8 is by convex guiding cone
End is gradually to the arc-shaped transition in blade mounting surface outer end, in favor of the water being drawn into impeller 4 to be complied with to the centrifugation force direction of water
Along 7 water conservancy diversion of convex guiding cone, reach that resistance is small, the high effect of flow velocity, 5 lower end of volution blade and inside and convex deflection cone
Body 7 is fixedly connected, the swirl shapes of two volution blades 5 be by corresponding pump housing water inlet position vortex cambered surface 9 and perpendicular to
10 rounding off of spiral cambered surface of axis forms, the vortex cambered surface 9 be by blade mounting surface end gradually vertically and off-axis
Line direction is tilted in spiral type to external symmetry, so that the shape that the vortex arc face of two volution blades corresponds to pump housing water inlet is formed
It is tubaeform, in favor of increasing the liquid inlet soakage of pump steamer connection, and pass through the arc-shaped curved surface of convex guiding cone periphery
Reduce the resistance of pump housing water inlet water conservancy diversion, and then improve the work efficiency of water pump, meanwhile, the spiral cambered surface parallel to axis,
In favor of raising speed to entering water, the lift of water pump is improved.
The present invention can be equipped with water conservancy diversion in 9 upper surface of vortex cambered surface of two volution blades 5 and cut knife plate 11, described to lead
Stream cutting knife plate 11 is consistent with the gradient and curvature of vortex cambered surface 9, and 11 upper end of water conservancy diversion cutting knife plate is equipped with major cutting edge 12, side
Face is equipped with auxiliary-blade 13, and the 3 water inlet inner wall of cutterhead is radially provided with a palate and hangs down the flat cutter 14 of formula, and the outer end of the flat cutter 14 is set
There is blade, blade and the shearing of major cutting edge 12 of the flat cutter 14 coordinate, rotated by impeller 4, drive leading for 5 upper end of volution blade
Stream cutting knife plate 11 on major cutting edge 12 it is tangent with 14 blade of flat cutter and formed shear and auxiliary-blade again to being pressed from both sides in liquid
Miscellaneous strip substance cutting, and go out after through 5 water conservancy diversion of volution blade.
The present invention can be equipped with vortex blade 15, the vortex blade 15 and volution blade 5 vertically in 3 inner wall of cutterhead
Outer end is slidably connected, and further carries out strong shear to the strip substance of shearing to reach, significantly improves cutting effect, making property
Can more it stablize.
Cutterhead 3 of the present invention is threadedly coupled with the pump housing 1, facilitates adjustment major cutting edge 12 and 14 knife-edge gap of flat cutter to reach
Effect.
In the use of the present invention, starting pump power source, 2 impeller 4 of pump shaft rotates, and pumping liquid enters the pump housing 1, liquid
When into the water inlet of the pump housing 1, since the shape that the vortex arc face of two volution blades corresponds to pump housing water inlet forms loudspeaker
Shape considerably increases the liquid inlet soakage of pump housing water inlet, then is reduced by the arc-shaped curved surface of convex guiding cone periphery
The resistance of pump housing water inlet water conservancy diversion, and then the work efficiency of water pump is improved, meanwhile, the spiral cambered surface is parallel with axis always,
Reach and raised speed to entering water, improved the effect of pump head, in liquid suction process, the flexible material in liquid is through whirlpool
After revolving major cutting edge 12 and 14 blade of the flat cutter shearing in cambered surface, with the water conservancy diversion and impeller 4 of water conservancy diversion cutting knife plate 11 rotate from
The heart acts on, in the secondary knife after the shearing of the level-one of 14 blade of major cutting edge 12 and flat cutter, then by 11 side of water conservancy diversion cutting knife plate
Sword 13 carries out two-stage centrifugal cutting, finally using volution blade outer end and blade inner wall under the centrifugal flow guiding of volution blade
The three-level strong shear of vortex blade, avoid soft strip substance causes to block due to shearing is not thorough, and makes cutting pump can not
The substance deficiency of normal operation significantly improves the drainage efficiency of cutting pump.
Simple in structure, easy to operate, cutting efficiency is high, increases liquid inlet due to using the above structure, having by the present invention
Flow velocity, improve pump efficiency, using it is reliable the advantages that.
