Description
Technical field
The utility model relates to a kind of sewage pump, is specially a kind of cutting type sewage pump.
Background technique
Generally all more complicated is severe for the operating environment of sewage pump; often can with foreign material such as pasture and water, long fibre, cloth, little branches in sewage; these foreign material, once be inhaled in pump, will be wound around or block impeller and impeller cannot be run well, and have had a strong impact on the working life of water pump.
Model utility content
For the problems referred to above, the utility model devises a kind of cutting type sewage pump, and it is provided with cutting device at the water intake position of water pump, the foreign material entering water pump can be made first to be shredded and discharge via impeller, effectively can avoid the generation of impeller stuck phenomenon, extend the working life of water pump.
For achieving the above object, the utility model is by the following technical solutions:
A kind of cutting type sewage pump, comprise the pump housing and be arranged on motor, the impeller in the pump housing, it is characterized in that: the described pump housing is provided with cutting device at its water intake position, this cutting device is made up of fixation cutter head and cutting knife two-part, wherein fixation cutter head is connected in the water intake of the pump housing, described cutting knife is arranged in fixation cutter head endoporus and with impeller coaxial positioning on electric machine main shaft, whole cutting knife comprises the Cutter apron of band pipelined channel, Cutter apron is provided with at least twice blade, the outer wall of blade and the inner hole wall Spielpassung of fixation cutter head.
Further, the Stainless Steel Alloy of above-mentioned cutting knife material selection high strength.
The utility model utilizes the High Rotation Speed of high strength cutting knife in cutting device, the foreign material such as the pasture and water in sewage, fiber, cloth, little branch effectively can be pulverized and stirred, large and long foreign material are avoided to enter in the pump housing, stop the generation of impeller stuck phenomenon, effectively can extend the working life of sewage pump, there is safety, reliably, without the feature of blocking.
Accompanying drawing explanation
Fig. 1, the utility model sewage pump structure sectional view;
The perspective view of Fig. 2, the utility model cutting device;
Fig. 3, the perspective view of the utility model cutting knife.
Embodiment
As Figure 1-3, a kind of cutting type sewage pump, the motor 2, the impeller 3 that comprise the pump housing 1 and be arranged in the pump housing, the described pump housing 1 is provided with cutting device 4 at its water intake position.
Described cutting device 4 is made up of fixation cutter head 41 and cutting knife 42 two-part.Wherein fixation cutter head 41 is directly connected in the water intake of the pump housing 1.Described cutting knife 42 and impeller 3 coaxial positioning are on electric machine main shaft 21, cutting knife 42 cooperation is installed in fixation cutter head 41 endoporus, whole cutting knife 42 comprises the Cutter apron 422 of band pipelined channel 421, Cutter apron 422 is provided with at least twice blade 423, blade 423 adopts twice in the present embodiment, be set as three roads or more as required in practice, the outer wall of each blade 423 and the inner hole wall of fixation cutter head 41 are that small―gap suture is equipped with.
The Stainless Steel Alloy of described cutting knife material selection high strength, and its blade 423 thickness and highly all much larger than the size of impeller 3, there is the feature of high strength height torsion, along with the High Rotation Speed of cutting knife 42, the foreign material such as the pasture and water in sewage, fiber, cloth, little branch effectively can be pulverized and stirred, large and long foreign material are avoided to enter in the pump housing 1, stop the generation that impeller 3 is wound around stuck phenomenon, effectively can extend the working life of sewage pump, whole sewage pump has safety, reliably, without the feature of blocking.
The above, it is only better embodiment of the present utility model, not any pro forma restriction is done to model utility, every according to know-why of the present utility model to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solutions of the utility model.
