Abstract
The utility model provides an aeration nozzle and a preparation box, and effectively solves the problems that solid-liquid mixtures such as coal slime and sludge are easy to mix unevenly and easy to layer and deposit during storage, the aeration nozzle is easy to block and difficult to clean, and the like. An air flow channel is arranged in the aeration nozzle, the air flow channel penetrates from the tail part of the aeration nozzle to the head part of the aeration nozzle, and the air flow channel mainly comprises a nozzle inlet, a rear cavity, a throat-shaped cavity, a main body cavity and a spray hole which are sequentially arranged from the tail part of the aeration nozzle to the head part of the aeration nozzle; the diameter of the rear cavity is gradually reduced from the inlet to the outlet, and the diameter of the main body cavity is gradually increased from the inlet to the outlet. The aeration nozzles form a circle of aeration nozzle group, the aeration nozzles in the circle of aeration nozzle group are annularly and uniformly distributed, and the aeration nozzle group is mounted on the inner wall of the preparation box; and a plurality of circles of aeration nozzle groups are arranged and are sequentially distributed from top to bottom.
