Detailed description of the invention
With reference to the accompanying drawings, the slurrying stirring system of this kind of pneumatic mortar machine, is applied in the mud jacking construction of civil engineering, for the preparation of various mud jacking slurries, comprises cement slurry preparing barrel 2, stirring motor 1, agitator, slush pump 5 and three-way diverter valve 6.Agitator adopts commercial goods---the double-sided impeller 3 of outsourcing, and the surrounding of double-sided impeller 3 upper and lower end rotating shaft is provided with slurry inlet, and the outer side edges surrounding in the middle part of double-sided impeller is provided with serum outlet.Stirring motor 1 is located on the axis above cement slurry preparing barrel 2, is connected with double-sided impeller 3, and double-sided impeller 3 is arranged on cement slurry preparing barrel middle position.Slush pump 5 is arranged on bottom cement slurry preparing barrel 2, is connected with cement slurry preparing barrel grout outlet 4 by pipeline.Three-way diverter valve 6 is arranged on cement slurry preparing barrel 2 upper lateral part, and by being tangential direction with the barrel of cement slurry preparing barrel, pipeline is connected cement slurry preparing barrel pulp inlet 7.After energising, stirring motor 1 drives double-sided impeller 3 to carry out Inner eycle stirring, and slush pump 5 carries out external circulation stirring to the slurries in cement slurry preparing barrel 2.
Embodiment:
During work, water and press mortar are injected cement slurry preparing barrel 2 in the ratio designed, after starting the stirring motor 1 of 2.2 kilowatts, the double-sided impeller 3 of 200 mm dias is driven to rotate with the speed of about 960 revs/min, double-sided impeller 3 by slurries in the slurry inlet intake impeller body of upper/lower terminal, sprayed along rolling tangential direction by the serum outlet at middle part, to reach the object of circulation stirring slurries again.Meanwhile, slush pump 5 sucks slurries from cement slurry preparing barrel grout outlet 4, and sends into three-way diverter valve 6, then sprays slurries from cement slurry preparing barrel pulp inlet 7, and slurries are moved downward along the bucket wall tangential direction rotation of cement slurry preparing barrel 2, to reach the object of circulation stirring slurries.Inner eycle of the present invention and outer circulation interact mixing in slurry process, make water and cement rapid mixing become the slurries meeting and be in the milk and require.After mixing slurry operation completing, double-sided impeller 3 quits work, and three-way diverter valve 6 points to and stores slurry bucket, and slush pump 5 feeding of being pressurizeed by slurries stores slurry bucket, once mixes slurry operation and completes.
The slurrying stirring system advantage of pneumatic mortar machine of the present invention is: substantially increase and mix slurry efficiency, and under equal energy consumption, pulping efficiency promotes 10 times than prior art.In addition, because the resistance of double-sided impeller agitator is much smaller than the blade mixer of prior art, so use the power consumption of stirring motor to be reduced to 2.2 kilowatts by 5.5 kilowatts of prior art, energy consumption has greatly been saved.
