[0002] With the continuous improvement of environmental awareness, governments of various countries have introduced strict environmental laws and policies, and put forward higher requirements for sludge treatment. It is required that sludge treatment must meet certain environmental standards, reduce pollution to the environment, and achieve sustainable use of resources. The construction quality of traditional sludge solidification equipment is relatively poor. With the continuous development of material science and engineering technology, sludge solidification technology is also constantly innovating and improving. The optimization of solidification process and the improvement of construction equipment have continuously improved the efficiency and quality of sludge in-situ solidification.

[0003] During the on-site construction process, it was found that the old-style sludge solidification mixing head did not mix evenly during construction, the molding integrity was poor, and it was easy for interlayers and gaps to not solidify properly. Any slight disturbance during subsequent construction would cause cracking and deformation, requiring rework and re-mixing, which added a lot of time and economic costs. Therefore, it was necessary to use a multi-disc rotary grouting mixing head that could cut the sludge and fill the fixed material simultaneously to fully mix the solidifying material and silt.

[0012] Preferably, the top pipe is truncated cone-shaped, and the second crushing roller located at the top is located inside the top pipe.

[0013] The beneficial effects of the present invention are:

[0014] 1) The input pipe delivers slurry, and the hydraulic pipe provides power for the hydraulic motor. The hydraulic motor drives the rotating shaft to rotate. The rotating shaft is connected to the slurry delivery pipe in the shaft as a whole. Therefore, the slurry delivery pipe in the shaft rotates synchronously, and the input pipe will input the solidified slurry into the slurry delivery pipe in the shaft through the universal slurry delivery device, and then output it to the bottom pipe through the outlet hole, thereby achieving the effect of spraying the solidified slurry. At the same time, the rotating shaft drives the cutter head body to rotate, so that the cutter head body drives the blade to cut and roll the sludge, so that the sludge can be input with solidified slurry and cut and stirred at the same time, which enhances the mixing effect of solidified slurry and sludge, thereby indirectly improving the solidification effect of sludge.

[0015] 2) When the rotating shaft rotates, it will also drive the bottom pipe to rotate with the rotating shaft, so that the entire output mechanism rotates with the rotating shaft. The solidified slurry will flow from the outlet to the bottom pipe, and then flow into the first circular pipe, and then flow into the second circular pipe, and then flow into the external sludge, so as to achieve the effect of transporting the solidified slurry to the sludge. During stirring, the sludge and soil lumps will collide with the push plate, and the push plate will push the first circular pipe and the second circular pipe to rotate. The accumulated sludge on the inside of the first circular pipe will be torn and split by the first crushing roller, and the force pushing the push plate is different. Therefore, the second circular pipe and the first circular pipe will produce relative rotation, and the accumulated sludge in the second circular pipe will be torn and split by the second crushing roller, so that the solidified slurry can be better sprayed out from the first circular pipe and the second circular pipe.

[0016] 3) When a hard object directly hits the top pipe, the inclined surface of the top pipe can be used to make the hard object push the top pipe to rotate, and the top pipe pushes the second round pipe to rotate, thereby reducing the impact force of the hard object. When the hard object collides with the roller bar, the roller bar will also rotate, causing the hard object to change the direction of impact, thereby reducing the impact force of the hard object on the top of the second round pipe.
