Breathable dust-reducing device on air cushion belt conveyor

气垫带式输送机上的透气降尘装置

Abstract

The utility model discloses a breathable dust-reducing device on an air cushion belt conveyor. The breathable dust-reducing device comprises a base plate connected to a sealing cover arranged at the upper part of the air cushion belt conveyor through a screw, wherein a rain-proof cover is welded at the upper part of a ventilation pipe; the lower part of the ventilation pipe is welded with the base plate; grid plates are welded inside the ventilation pipe in a layering and staggered manner; threaded holes are formed in plate surfaces of each layer and are screwed by bolts; the diameter of each threaded hole is 3 mm; and the threaded holes are uniformly distributed in the grid plates with the row pitch of 30 mm. The breathable dust-reducing device adopts a lengthened ventilation pipe so as to increase the airflow process; the porous grid plates are arranged inside the ventilation pipe in a staggered manner to enable the airflow directions to be changed repeatedly in the flowing process, so as to reduce impact of high-speed airflow and to enable a fluid field of the air to be an eddying flow; and meanwhile raise dust gradually deposits during passing the porous grid plates, so as to achieve the purpose of reducing raising dust.
本实用新型公开了气垫带式输送机上的透气降尘装置,它包括底座板通过螺钉与气垫式输送机上部的密封罩连接,通风管上部焊接有防雨罩,通风管下方与底座板焊接,通风管内部分层交错焊接有栅板,所述的栅板每层的板面上开有螺纹孔用螺栓拧紧。所述的螺纹孔直径3mm。孔距30mm均匀分布在栅板上。本实用新型采用加长通风管,目的是增加气流的流程,在通风管内部交错布置有多孔栅板,使气流在流动过程中多次改向,从而降低高速气流的冲击,使压力气体的流场变成紊流,而且扬尘经过多孔栅板的过程中逐层沉淀,达到减少扬尘的目的。
