By the both sides at impeller the first rotating blade and the second rotating blade are set respectively, when pollution discharge pump is worked, the first rotating blade and the second rotating blade also can rotate under the drive of pump shaft, blade can carry out comminuted cutting to the pollutant that enters in the pollution discharge pump, bulky solid particulate matter is cut into the little pollutant of volume, and so that fibrous pollutant can't twine, can seize, make the pollutant after the pulverizing easier in pollution discharge pump, do not stop up.
As of the present utility model preferred, described the first rotating blade and described the second rotating blade are the ring blade, and described ring blade is provided with overflow hole.By at the first rotating blade and the second rotating blade one overflow hole being set, overflow hole can stop pollutant to pass through the first rotating blade and the second rotating blade.
In order to increase the cutting function of the first rotating blade and the second rotating blade, described the first rotating blade and described the second rotating blade are provided with spiral cutter teeth.
In order to strengthen the first rotating blade and the second rotating blade to the cutting function of the pollutant of different direction, described the first rotating blade and described the second rotating blade are provided with two circle spiral cutter teeths.
For pollutant is discharged pollution discharge pump better, the bottom of the pump housing of described pollution discharge pump is provided with blowdown valve.
In order to regulate the flow of entrance sleeve, the entrance point of the entrance sleeve of described pollution discharge pump is provided with the import one-way valve.
The beneficial effects of the utility model are:
By the both sides at impeller the first rotating blade and the second rotating blade are set respectively, the utility model can be cut into bulky solid particulate matter the little pollutant of volume, and so that fibrous pollutant can't twine, can seize, make the pollutant after the pulverizing easier in pollution discharge pump, do not stop up.The advantage such as just outer the utility model also has compact structure, volume is little, noise is little and energy-saving effect is remarkable.
