For this reason, people have done improvement to original Submerged Motor Pumps, be provided with cutting device by inlet end at Submerged Motor Pumps, as the patent No. be: 200520046465.7, notice of authorization number is: CN 2830724Y, a kind of novel water pump cutting device was disclosed on October 25th, 2006, and it includes fixed base and leafy chip cutting impeller, fixed base is installed on the position of the pump housing with respect to water intake, and offers the mouth of a river.Fixed base transfixion in the use, cutting impeller rotates under the driving of motor shaft, produce relative movement between the two, tangent gap forms shearing force between fixed base and the cutting impeller, thereby the dirt that sucks is cut, tears, effectively solved problems such as dirt obstruction, winding Submerged Motor Pumps.But existing electric pump is because employing multiple-blade half-opened impeller hydraulic efficiency is low, distribution power is big, the manufacture cost height wastes energy again, and the shearing force that the electric pump of this kind structure only relies on the acute angle angle of the knife face of blade and fixed base to form, with realization dirt is cut, tears, but dirt produces slippage, accumulation at cutting edge easily, cause shearing, tear effect and descend, and the cutting part of fixed base and cutting impeller wears no resistance, influence the working efficiency of Submerged Motor Pumps.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure in order to solve the deficiency that above-mentioned prior art exists, installation, easy to use, high working efficiency and anti-winding, the cutting type sewage dirt Submerged Motor Pumps that anti-blockage capability is strong.
For achieving the above object, the utility model adopts following scheme: a kind of cutting type sewage dirt Submerged Motor Pumps, include the black box and the cutting device of motor, the pump housing, electric pump, wherein cutting device is made up of impeller and the cutting disk that is installed in pump housing water inlet position place, offer water inlet on the cutting disk, described cutting disk water inlet is a polygonal-shaped openings, and is distributed with serrated edge on the peripheral position of water inlet.
The utility model further is set to: described water inlet is six prismatic openings, is distributed with one group of serrated edge on each limit of six prismatic water inlets, and every group of blade is made up of a big serrated knife blade and two little serrated knife blade.
Described cutting disk is provided with some radial skewed slots with respect to the surface of pump housing inner chamber.
Be evenly distributed with 12 skewed slots on the surface of described cutting disk with respect to pump housing inner chamber, and the cross section of skewed slot is semicircle.
Described impeller is provided with the semi-open shape blade that roughly is the involute shape, is embedded with the diamondite cutter head on the medial extremity end of blade.
The beneficial effects of the utility model are: the utility model compared with prior art, by existing electric pump cutting disk is improved, the cutting disk water inlet is set to six prismatics, and is evenly distributed with the blade group that is made of large and small serrated edge on the hexagon of water inlet; Being evenly distributed with cross section on the surface of cutting disk with respect to pump housing inner chamber is semicircular 12 skewed slots; In addition, impeller adopts the semi-open shape blade that roughly is the involute shape, is embedded with on the medial extremity end of blade and the corresponding diamondite cutter head of blade.The utility model utilizes serrated edge on the cutting disk and the alloy cutter head on the blade medial extremity, and lip-deep semicircle skewed slot seamed edge of cutting disk and the outer lateral edges of blade, form sawing and shearing mutually, with the foreign material in the medium carry out sawed-off, tear, shred etc., avoided foreign material to produce slippage, accumulation, caused shearing, tearing the drawback that effect descends at cutting edge.The utility model is simple and reasonable for structure, use, easy for installation, and cutting power is strong, and the cutting part wear resistance is strong, has improved the pollution discharge capability and the working efficiency of electric pump greatly, avoids dirt to stop up electric pump.
Below in conjunction with embodiment and accompanying drawing the utility model is further specified.
