Description

Combined type filter-pressing coal slime crushing and pulping integrated machine

[ technical field ] A method for producing a semiconductor device

The utility model relates to a broken slurrying equipment technical field of filter-pressing coal slime, concretely relates to broken slurrying all-in-one of combined type filter-pressing coal slime.

[ background of the invention ]

The coal slime is one of the solid wastes with the largest discharge amount in China at present, and the filter-pressed coal slime is rich in 30-50% of coal, so the recycling of coal slime recycling resources is a necessary choice for energy structures mainly based on coal in China. However, the original coal slime is subjected to flotation, soaking, stirring and filter pressing, so that coal and slime are mutually adsorbed and completely argillized, the argillized coal slime with large water content has poor crushing effect and is easy to cause equipment blockage in the crushing process, so that the equipment cannot normally operate, and even if the existing coal slime pulping equipment is used for further pulping, the existing coal slime pulping equipment still has poor pulping effect and cannot provide excellent coal slime pulp for next coal slime flotation.

In the prior art, publication numbers CN205288605U, CN104785336A, CN205628208U, CN107855188A and CN208356951U disclose several coal slurry crushers, and cutting the coal slurry by using blades, cutters or rotary knives, which achieve a certain crushing effect, but for filter-pressing coal slurry with water content of 20-30%, the device will adhere to the inner wall of the crusher due to high water content and strong viscosity, which causes the blockage of the crusher, and the coal slurry crusher cannot work normally. In addition, chinese patent CN201735359U, 2011 2/9 discloses "heavy calcium slurry high-speed dispersion bucket", this equipment includes the storage bucket and installs the (mixing) shaft at the storage bucket center, drive mechanism is equipped with on (mixing) shaft upper portion, respectively be equipped with a circular dispersion impeller in the middle part and the lower part of (mixing) shaft, this kind of mode of setting makes ore pulp body foam many, the defoaming effect is poor, the ore pulp rotational speed that the pivot was kept away from to the agitator is low, it is longer to cause the time of dispersion work, coal slurry dispersion effect is poor, fine coal slime granule dissolves the not good state.

Chinese patent CN205746949U discloses a coal slime crushing and stirring all-in-one machine, which adopts multiple groups of crushing blades as crushing units, and the crushed coal slime enters into a stirring assembly and is mixed with water through a stirring paddle.
