Technical Problem

[0003]现有钢渣清理多采用吸风式装置,但其吸风嘴设计存在缺陷,吸风口入射角度与缝隙高度设计不合理:传统吸风嘴的吸风口多与吸嘴主体中心轴线垂直,吸入口为等高度直缝结构,该设计导致气流入射方向与钢板表面钢渣的附着方向不匹配,气流难以对附着较紧的钢渣形成有效剥离力;同时,传统缝隙高度设计大多凭经验设定固定高度,存在为达到预期清理效果,需被迫提高总风量或风速,不仅增加风机能耗,还可能因气流过度冲击钢板表面,导致钢板微小形变(尤其薄规格钢板),反而影响产品精度;此外,不合理的缝隙高度还会导致吸风范围与钢板宽度适配性差,要么出现局部吸风覆盖不足(漏吸钢渣),要么出现超出钢板宽度的无效吸风(浪费风量)

Benefits of technology

[0049]该吸风嘴装置,包括吸嘴主体和吸风口;吸嘴主体具有腔室;所述吸嘴主体的一端设有与所述腔室连通的开口;吸风口设于所述开口处;其中,所述吸风口与所述吸嘴主体的中心轴线呈一倾斜角度,使得所述吸风口的底部边缘与所述吸嘴主体的侧壁内表面之间形成一吸入口缝隙;所述吸入口缝隙的高度基于目标工件所需的总风量、目标风速以及所述吸入口缝隙的宽度来确定。

Abstract

The application relates to an air suction nozzle device and a design method thereof. The air suction nozzle device comprises a nozzle body with a cavity; one end of the nozzle body is provided with an opening in communication with the cavity; an air suction port is arranged at the opening; the air suction port and the central axis of the nozzle body form an inclined angle, so that a suction inlet gap is formed between the bottom edge of the air suction port and the inner surface of the side wall of the nozzle body; the height of the suction inlet gap is determined based on the total air volume required by a target workpiece, a target air speed and the width of the suction inlet gap. Through accurate calculation and optimization of the inclined air suction port, the gap height and the air speed, the optimal gap height H is obtained, the uniform, efficient, energy-saving and reliable adsorption effect is realized under the premise of capturing particles, unnecessary air volume waste is avoided, the cleaning blind area of a traditional wide-gap nozzle is completely solved, and the cleaning efficiency is improved.
