Embodiment 1
[0028] The steelmaking waste slag slurry treatment system is characterized in that it includes the following treatment steps:
[0029] S1. Filtration: pump the steelmaking waste slag slurry into the filter box 1 for filtration to remove large particles of impurities;
[0030] S2, cooling: collecting the filtrate filtered by S1, and cooling the filtrate through the cooling mechanism 2;
[0031] S3, grinding: adding the cooled filtrate into the grinding box 3 for grinding;
[0032] S4, iron removal: Add the ground filtrate to the iron removal mechanism 4 to remove iron, and then recycle the filtrate after iron removal,
[0033] The invention processes the steelmaking waste slag slurry treatment system through the steps of filtration-cooling-grinding-iron removal, and processes the slurry through a complete set of processes, which can remove the iron in the slag slurry, and the remaining part can be reused, which is relatively easy Waste less.
Embodiment 2
[0035] On the basis of Embodiment 1, the filter box 1 includes a filter box body, an inclined filter screen 5 is arranged in the filter box body, and a liquid outlet pipe is provided at the bottom end of the inclined filter screen 5, which can increase the uniformity of grinding in the subsequent grinding step. Spend.
Embodiment 3
[0037] On the basis of Embodiment 1, the cooling mechanism 2 includes a cooling pipe 6, the liquid inlet end of the cooling pipe 6 is connected to the liquid outlet pipe, and a condensation jacket 7 is sleeved on the outside of the cooling pipe 6, and a water inlet pipe and a water inlet pipe are arranged on the condensation jacket 7. The outlet pipe, the inner wall of the cooling pipe 6 is provided with an inwardly recessed groove 8, the groove 8 is evenly arranged on the inner wall of the cooling pipe 6, and the filtered steelmaking waste slag slurry is cooled and then ground to reduce its temperature , and the heat is transferred to the water in the condensation jacket through heat transfer to reduce the heat loss, increase the heat transfer efficiency and reduce the heat loss.
