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, is only 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, and interior finger leans on axial ray 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, single-screw centrifuges removing sludge, including motor 1, pump chamber 2, pump case 3, impeller 4, main shaft 5 and diversion chamber
6.Pump chamber 2 is made of two parts, including shaft coupling room 21 and closed chamber 22, passes through bolt between two groups（It is not shown）It is fixed to connect
Connect.
Specifically, motor 1（Existing removing sludge mainly uses hydraulic electric motor）The top of pump chamber 2, its turn are locked in by bolt
Axis is stretched into the shaft coupling room 21 on 2 top of pump chamber to be coupled 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 lower part 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 connection mode are then fixed in the head of impeller 4 by way of key connection
Similarly to the prior art.4 main body of impeller is located in the annular compartment 31 of pump case 3.The right side of pump case 3 has horizontally disposed export mouth
32, the opening of lower section is connected with diversion chamber 6.Export mouth 32 is in inner small and outside big, and diversion chamber 6 is then in up big and down small horn-like.
