The cut surface gone out；Cut surface is vertical with axis.
Preferably, along axis from bottom to top, the spiral centrifugal section radius of corresponding cut surface is gradually wide；The spiral at remaining position from
Heart section radius is constant.
Preferably, the angle of spiral centrifugal section and axis is less than 45 °.
Preferably, along axis from bottom to top, angle tapers into.
Preferable angle is 45-10 °.
Preferably, spiral centrifugal Duan Weiyi is enclosed between a circle half.
Preferably, screw blade is used with impeller base and is integrally cast.
Preferably, the material of impeller is evanohm.
By using above-mentioned technical scheme, the beneficial effects of the utility model are：Wheel bottom has vertical with axis
Cut surface, realize scissor cutting strip debris, reduce debris winding impeller, prevent the generation blocked.Cut surface, which also has, is oriented to work(
Can, near debris directing vane wheel seat, chamber is promoted along spiral centrifugal section axial screw, finally centrifuges discharge upwards in slightly-inclined,
Discharge pressure is strong, distance is remote, is advantageous to strengthen the suction of removing sludge.The utility model is simple in construction, can shear solid or band
Shape debris and impeller normal operation is not influenceed, lossless performance is good, efficiency high, strengthens that the intake performance of pump is good, has excellent anti-
Cavitation performance.

Embodiment
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
The direction term being previously mentioned in the utility model, only it is for the location status of Figure of description 1, above refers to
The top of Figure of description 1, under refer to the lower section of Figure of description 1, axis refers specifically to the central shaft of main shaft, interior to refer to close to axis position
Put, refer to outside away from axial location, therefore the direction term used is intended to be illustrative and not intended to limit the utility model.
As shown in figure 1, without blocking removing sludge, including motor 1, pump chamber 2, pump case 3, impeller 4, main shaft 5 and cutterhead 6.Pump chamber 2
It is made up of two parts, including shaft coupling room 21 and closed chamber 22, passes through bolt between two groups（It is not shown）It is fixedly connected.
Specifically, motor 1（Existing removing sludge mainly uses hydraulic electric motor）The top of pump chamber 2, its turn are locked in by bolt
Shaft extension enters to be coupled in the shaft coupling room 21 on the top of pump chamber 2 with main shaft 5, i.e. motor 1 and main shaft 5 in shaft coupling room 21 in passing through shaft coupling
Device 7 couples.The bottom of main shaft 5 is then supported on closed chamber 22 by seal 8 and bearing 9, and the bottom of closed chamber 22 is also equipped with
End cover（It is not shown）.The bottom of main shaft 5, specific connected mode are then fixed in the head of impeller 4 by way of key connection
Similarly to the prior art.The main body of impeller 4 is located in the annular compartment 31 of pump case 3.The right side of pump case 3 has horizontally disposed export mouth
32, lower section is provided with horn-like introducing port 33 and connected.Export mouth 32 is in inner small and outside big, and introducing port 33 is in then up big and down small loudspeaker
Shape, the curvature of bottom are less than the curvature on top, reduce and import flow, and enhancing pump case negative pressure is formed, and improves the absorption affinity of pump case.Knife
