Description
Technical field
The utility model is related to a kind of sewage grinding pumps.
Background technology
In use, due to bad environments, foul is more for sewage pump, easily blocks, influences the normal of sewage pump
Work, it is serious to burn out motor, in the prior art, it will usually be filtered using filter mantle, the filter mantle of fine grid is easy
It blocks, the filter mantle of vegetable grid can not filter larger sundries.
Utility model content
The utility model is according to the above deficiency, provide a kind of sewage grinding pump.It can grind in use larger
Sundries improves the using effect of water pump, extends the service life of water pump.
The technical solution of the utility model is：
A kind of sewage grinding pump, including：
Water pump cover；
Water pump cover plate；
Motor, in water pump cover and water pump cover plate；
It is characterized in that it further includes：
Sewage grinding knife is fixed with the main shaft of motor and outside water pump cover plate, multiple water is offered on water pump cover plate
Pump water inlet hole, when blade rotation of sewage grinding knife, can cover multiple water feeding of water pump holes.
When sewage and sundries are into before water feeding of water pump hole, first through sewage grinding knife, bulky grain is ground into little particle.
In order to improve grinding effect, the blade of the sewage grinding knife is close to the setting of water feeding of water pump hole, during blade rotation with
Water feeding of water pump hole forms shear structure.
It is close to the water feeding of water pump hole and is provided with inclined-plane, the rotation direction satisfaction of the sewage grinding knife first passes through inclined-plane again
By water feeding of water pump hole.
There is an inclined-plane, blade easily forms shear structure with water feeding of water pump hole during blade rotation, further improves shearing effect
Fruit.
Preferably, the trapezoidal shape in the section of the blade, the edge of a knife are acute angle.
In order to facilitate maintenance, abrasive sheet is replaced, the water pump cover plate includes motor mounting plate and abrasive sheet, motor installation
Plate, for fixing motor bearings, the ground screw of abrasive sheet is fixed with motor mounting plate, and abrasive sheet is detachable, the water pump
Inlet opening is arranged on abrasive sheet.
Preferably, the abrasive sheet is made of quenched and tempered steel.
The water pump cover plate is made of casting material, and the motor mounting plate is fixed on through mounting screw on water pump cover plate.
The utility model has advantageous effect that is simple in structure, at low cost, extending electrical machinery life, improve grinding efficiency.
