The fixed rod 11 and the rotary cover 12 are connected by adopting threads, and through the design, the fixed rod 11 and the multi-face rotor 34 on the fixed rod 11 are fixed, and the fixed rod 11 is conveniently rotated to drive different faces of the multi-face rotor 34 to contact with the connecting rod 25.
The auxiliary turbulence device mainly comprises a baffle plate 8 and triangular saw teeth 13, wherein the triangular saw teeth 13 are arranged on the inner end surface of the baffle plate 8, and the baffle plate 8 is provided with a filtering hole 14.
The number of the baffles 8 is 4 and the baffles are uniformly distributed in the circumferential direction, and the height value of each baffle 8 is 10 times of the length value of each baffle 8; the filter holes 14 are circular holes, the number of the filter holes 14 is 2 columns and 37 columns.
The invention realizes vortex crushed aggregates 3, shearing crushing and crushed aggregates 3 filtering respectively through the baffle plate 8, the triangular saw teeth 13 and the filtering holes 14 in the auxiliary turbulence device, in particular to a combined turbulence plate stirring material barrel 2 for stirring mixed liquid of crushed aggregates 3 and water 4 when equipment works, so that the crushed aggregates 3 generate rotary motion, when the crushed aggregates 3 move to the baffle plate 8, the baffle plate 8 blocks the crushed aggregates 3 and the water 4 to form vortex at the baffle plate 8, and the crushed aggregates 3 in the vortex and the crushed aggregates 3 stirred by the combined turbulence plate collide with each other for crushing so as to accelerate crushing decomposition of the crushed aggregates 3; the crushed aggregates 3 which are not easy to stir and decompose in the crushed aggregates 3 can be decomposed by shearing and crushing the triangular saw teeth 13, namely, the hard crushed aggregates 3 which are not easy to decompose are sheared and torn by the triangular saw teeth 13 on the baffle plate 8, so as to assist the crushing and decomposition of the crushed aggregates 3; the filtering holes 14 on the baffle plate 8 can carry out auxiliary filtering screening on the crushed aggregates 3 after stirring and decomposing, namely, only the crushed aggregates 3 smaller than the filtering holes 14 after crushing can pass through the filtering holes, so that the auxiliary filtering on the crushed aggregates 3 after stirring and decomposing is realized.
