阅读说明：本技术 一种用于旋流器落料的可调式下料嘴 (Adjustable blanking nozzle for blanking of cyclone ) 是由 刘建华 金绍武 王海会 张超 于 2020-12-31 设计创作，主要内容包括：本发明涉及自然砂采矿领域。即一种用于旋流器落料的可调式下料嘴。包括法兰,下料套,下料嘴壳体和调节装置,下料套设置在下料嘴壳体内部,调节装置设置在下料嘴壳体的一侧或两侧,可调式下料嘴通过法兰与旋流器出料口相连接。特点是,通过下料嘴壳体一侧或两侧设置的调节装置改变下料套的形状,从而改变下料套的截面积,达到改变出料浓度的目的。有益效果是：在不停产的情况下,实现人为调节或自动调节出料浓度的功能,提高了生产率,提高了年产量。(The invention relates to the field of natural sand mining. Namely an adjustable blanking nozzle for blanking of a swirler. The adjustable blanking nozzle comprises a flange, a blanking sleeve, a blanking nozzle shell and an adjusting device, wherein the blanking sleeve is arranged inside the blanking nozzle shell, the adjusting device is arranged on one side or two sides of the blanking nozzle shell, and the adjustable blanking nozzle is connected with a discharge hole of a swirler through the flange. Is characterized in that the shape of the blanking sleeve is changed by the adjusting device arranged at one side or two sides of the blanking nozzle shell, thereby changing the sectional area of the blanking sleeve and achieving the purpose of changing the discharging concentration. The beneficial effects are that: under the condition of no production stop, the function of manually adjusting or automatically adjusting the discharging concentration is realized, the productivity is improved, and the annual output is improved.)
