The technical solution adopted in the utility model is:
A kind of proof submersible sand discharging pump of belt cutter tool, be provided with one group at the fluid intake place of pump by cutting tool that static blade, cutting blade constituted, static blade is fixedly installed in the fluid intake place of the pump housing, cutting blade is installed on the shaft end of water pump spindle, cutting blade matches with static blade, and cutting blade can rotate with water pump spindle.
Matching gap is the 0.1-0.2 millimeter between cutting blade and the static blade.
Static blade is the disc type sheet structure, and there is an axis hole centre, is provided with some permeable holes around intermediate shaft hole.
Cutting blade is a leaf structure, and blade edge is sharp edge of a knife shape, and blade face is paddle formula structure, and a transmission shaft that is connected with water pump spindle is arranged in the middle of the cutting blade.
The utility model beneficial effect is:
Owing to adopted the proof submersible sand discharging pump of a kind of belt cutter tool of the present utility model, thereby solved the problem that existing proof submersible sand discharging pump does not have agitating function and the easy seize of fibrous object is twined solid particle in the cesspool, the proof submersible sand discharging pump of a kind of belt cutter tool of the present utility model has: dynamic and static blade hydraulic performance is good, cooperate accurate, the hydraulic efficiency height, fibrous dirt had smashing cutting function, make fibrous dirt to twine, can seize, and the dirt after pulverizing is easier in the pump housing, the not characteristics that can result in blockage.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7.
A kind of proof submersible sand discharging pump of belt cutter tool, mainly by: handle 1, bearing 2, Stainless Steel Case 3, motor 4, intake pipe 5, mechanical seal 6, fuel tank 7, fuel tank cap 8, impeller 9, the pump housing 10, water pump spindle 11, water pump spindle axle sleeve 12, static blade 13, cutting blade 14 are formed.
A kind of proof submersible sand discharging pump of belt cutter tool, be provided with one group of cutting tool that is constituted by static blade 13, cutting blade 14 at the fluid intake place of pump, static blade 13 is fixedly installed in the fluid intake place of the pump housing 10, cutting blade 14 is installed on the shaft end of water pump spindle 11, cutting blade 14 matches with static blade 13, and cutting blade 14 can rotate with water pump spindle 11.
Matching gap is the 0.1-0.2 millimeter between cutting blade 14 and the static blade 13.
Static blade 13 is the disc type sheet structure, and there is an axis hole centre, is provided with some permeable holes around intermediate shaft hole.
Cutting blade 14 is a leaf structure, and blade edge is sharp edge of a knife shape, and blade face is paddle formula structure, and a transmission shaft that is connected with water pump spindle 11 is arranged in the middle of the cutting blade 14.
Cutting blade with good hydraulic performance, static blade.This structure is to twine and custom-designed a kind of pump additional device at easy precipitation of solid particle in the cesspool and the easy seize of fibrous object.Cutting blade and static blade precision-fit have smashing cutting function to fibrous dirt, make fibrous dirt to twine, can seize, and also the dirt after pulverizing is easier in the pump housing, can not result in blockage.Static blade has good hydraulic characteristic, guaranteeing that it has under the prerequisite of backwashing sewage water pond function, improves its hydraulic efficiency as much as possible, makes that the water pump after this function of increase does not need expanded motor power can meet the demands yet.
Static blade 13 is fixedly installed in the water intake of the pump housing 10; the axle that is in transmission connection with cutting blade 14 is fit in the center hole of static blade 13 then; the axle that is in transmission connection of cutting blade 14 is installed with the shaft end of water pump spindle 11 and is connected and fixed; regulate static blade 13 then; installation matching gap between the cutting blade 14 is to the 0.1-0.2 millimeter; after installing; pump is put into water; energising starts proof submersible sand discharging pump and just can blowdown use; during the submersible sewage pump work; static blade 13 is actionless; cutting blade 14 is to be fixedly installed on the shaft end of water pump spindle 11; rotation with water pump spindle 11 is rotated; when water pump spindle 11 rotary works; water pump spindle 11 just drives water pump vane and cutting blade 14 rotates together; sewage just is inhaled in the proof submersible sand discharging pump and by the water outlet from pump and discharges; in the process of sewer; because impurity is more in the sewage; pump intake sucks fibrous object through regular meeting; so because static blade 13; relative rotary motion between the cutting blade 14; make through static blade 13; whole passive blade 14 cutting and grinding of the impurity of cutting blade 14 make fibrous dirt to twine, can seize; dirt after the pulverizing is easier in the pump housing, can not result in blockage.Owing to the rotation stirring action of cutting blade 14, make cutting blade 14 have backwashing sewage water pond function simultaneously, thereby improve the efficient of proof submersible sand discharging pump, prolong the working life of proof submersible sand discharging pump.
