Machine, footing 3, as supporting construction, lays the pump housing 1, oil cylinder 2 and motor the most successively, and machine shaft 4 prolongs through oil cylinder 2
Extending the pump housing 1, be connected with the impeller 5 being located in the pump housing 1, the described pump housing 1 includes water inlet 6 and outlet 7, pacifies at water inlet 6
Equipped with cutter plate 8, described cutter plate 8 includes that ring flange 9, composite blade, described composite blade include being located at ring flange 9
Multiple one-level blades 11 on centre bore 10, it is located at multiple two grades of blades 12 of centre bore 10 inwall of ring flange 9；Described flange
The inner face of dish 9 is provided with cutter groove 13；On the described machine shaft 4 being between impeller 5 and oil cylinder 2, the motor that is in oil cylinder 2
One side mechanical oil seal 14, two-sided mechanical oil seal 15 it is respectively equipped with in rotating shaft 4；Described impeller 5 is provided with cutting blade 19, described moving knife
Sheet 19 is fitted with cutter plate 8.
Cutter plate 8 is arranged on the water inlet end face of the sewage cutting pump pump housing 1, the cutting blade 19 laminating coupling of impeller 5
At the inner face of cutter plate 8, sewage enters the pump housing from the centre bore of cutter plate 8, and the rubbish in sewage is entered by composite blade
Row is scraped, hook, is cut, thus is pulverized by bulky refuse, the beneficially discharge of sewage；Owing to the cutting blade 19 of impeller 5 is fitted in
The inner face of cutter plate 8, and inner face is provided with cutter groove 13, the rubbish flow velocity when entering the pump housing 1 is very fast, and some rubbish exist
The blade that is the most thoroughly combined cutting is put between impeller 5 and cutter plate 8 completely, now, impeller 5 high-speed rotation, drive rubbish
Rubbish rotates, and now, rubbish is hooked or be snapped in cutter groove 13 by cutter groove 13, the relative motion between impeller 5 and cutter plate 8,
Make the rubbish in cutter groove 13 by cutting further completely.
The plurality of one-level blade 11 is the most uniform, and the inwall laminating of one end and centre bore 10, the other end is at ring flange 9
Centre bore 10 be centrally formed intersection point；The plurality of two grades of blades 12 are circumferentially distributed on the inwall of centre bore 10；The plurality of
One-level blade 11 is set in distance with multiple two grades of blades 12.
Described oil cylinder 2 includes cylinder body 16 and cylinder cap 17, and described cylinder cap 17 mates at the pump housing 1 top.
Described impeller 5 includes end face body 18, the multiple cutting blades 19 being located on end face body 18, each cutting blade 19 with
