The stirring process and the working principle of the device are as follows:
cement, sand and water are fed into a feeding flaring 111 according to a preset proportion, then the mixture of the cement, the sand and the water is gradually and downwards transmitted from the top of a concrete mortar rough mixing channel 121 to be pushed to the middle section of the concrete mortar rough mixing channel 121 under the rotary transmission of an upper auger mortar blade 122, the mixture of the cement, the sand and the water at the middle section of the concrete mortar rough mixing channel 121 forms rough concrete mortar under the primary stirring of a mortar primary stirring pile 123, then the rough concrete mortar at the middle section of the concrete mortar rough mixing channel 121 continues to be pushed downwards under the rotary pushing of a lower auger mortar blade 124 until the rough concrete mortar is continuously fed into a mortar feeding groove 104 through a discharge pipe 120, and then the rough concrete mortar in the mortar feeding groove 104 continuously flows downwards into a vibration bin 26; mortar at the bottom of the oscillating bin 26 will gradually extrude downwards into the first vortex dispersing channel 17 through the vortex clockwise inlet end 98 under the gravity extrusion, and the mortar in the first mortar vortex dispersing channel 17 can be slowly fed along the vortex anticlockwise direction of the first vortex dispersing channel 17 under the extrusion effect of the mortar in the oscillating bin 26, when the mortar in the first vortex dispersing channel 17 is fed to the vortex center 29 in the anticlockwise direction and then continuously flows into the second vortex dispersing channel 15 from the clockwise end of the second vortex dispersing channel 15, and the mortar entering the second vortex dispersing channel 15 flows along the clockwise path of the second vortex dispersing channel 15, finally the mortar in the second vortex dispersing channel 15 is led out through the vortex clockwise leading-out end 11, the fine and smooth concrete mortar discharged from the vortex clockwise discharge end 11 flows out downwards along the mortar discharge groove 107;
meanwhile, the stepping motor 115 and the output gear 102 are controlled to do periodic reciprocating forward and reverse rotation at the frequency of 2-5 Hz, under the meshing transmission of the arc-shaped transmission rack 103, the output gear 102 does periodic reciprocating forward and reverse rotation at the frequency of 2-5 Hz, so that the first strip body 27 can periodically reciprocate and swing, mortar in the vibration bin 26 is in a continuous vibration state, and the effect of promoting the mortar at the bottom of the vibration bin 26 to be guided into the first vortex dispersion channel 17 is further realized; the first strip 27 swings periodically in a reciprocating manner to synchronously drive the reciprocating and revolving vortex oscillation strip 16 to do periodic reciprocating clockwise and counterclockwise rotation along the vortex center 29 with the frequency of 2-5 Hz; by controlling the output of the stepping motor 115, the rotation angle of the reciprocating rotary vortex oscillation strip 16 is 8-16 degrees in a unit period of periodic reciprocating positive and negative rotation of the reciprocating rotary vortex oscillation strip 16 by taking the vortex center 29 as a rotation center; therefore, the mortar flowing through the first vortex dispersing channel 17 and the second vortex dispersing channel 15 can be continuously stirred by the continuous reciprocating vibration of the plurality of first mortar reciprocating U-shaped mortar vibrating dispersing tablets 13 and the plurality of second mortar reciprocating U-shaped mortar vibrating dispersing tablets 14 respectively, so that particles in the concrete mortar flowing through the first vortex dispersing channel 17 and the second vortex dispersing channel 15 are mutually interpenetrated, sheared, slipped and diffused along the way, and finally the purpose of fine and uniform dispersion is achieved, and the concrete mortar finally discharged through the mortar discharging groove 107 is fine and dispersed fine mixed mortar;
the in-process that the mortar flowed through a vortex dispersion passageway 17 and No. two vortex dispersion passageways 15, because there is certain viscidity in the mortar, the mortar is slow flowing through the in-process velocity of flow of a vortex dispersion passageway 17 and No. two vortex dispersion passageways 15, influences discharge efficiency, and this kind of problem of solution that this device can be fine is as follows:
in the process of making the reciprocating and revolving vortex oscillation strip 16 to periodically reciprocate forward and backward with the vortex center 29 as the revolving center, the first vortex dispersing channel 17 and the second vortex dispersing channel 15 are periodically widened and narrowed;
when the reciprocating revolving vortex oscillation strip 16 rotates clockwise around the vortex center 29, the first vortex dispersion channel 17 gradually narrows, the second vortex dispersion channel 15 gradually widens, and mortar in the first vortex dispersion channel 17 is forcibly squeezed into the second vortex dispersion channel 15 which gradually widens to form negative pressure because the first vortex dispersion channel 17 gradually narrows;
the first vortex dispersing channel 17 can be gradually widened and the second vortex dispersing channel 15 can be gradually narrowed in the process that the reciprocating revolving vortex oscillation strip 16 rotates anticlockwise around the vortex center 29, at the moment, mortar in the oscillation bin 26 can more smoothly flow into the first vortex dispersing channel 17 which is gradually widened to form negative pressure, the mortar in the second vortex dispersing channel 15 can be forcibly extruded from the vortex clockwise leading-out end 11 due to the fact that the second vortex dispersing channel 15 is gradually narrowed, and therefore fine concrete mortar can be forcibly extruded in each period, the continuity of discharging and feeding is further enhanced, the discharging efficiency is improved, and the blocking phenomenon is prevented.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
