Spiral metal dust collecting device

Abstract

The invention provides a spiral metal dust collecting device, comprising a diverging pipe, a shell, a motor and vanes, wherein the vanes are fixed on a motor shaft of the motor and are arranged in theshell; one end of the shell has an opening, and air flow generated by rotation of the vanes under the driving of the motor enters the shell from the opening along an axial direction; the side wall ofthe shell is provided with an air outlet, and the air flow generated by rotation of the vanes under the driving of the motor is discharged from the shell via the air outlet along a circumferential direction; the diameter of the inlet of the diverging pipe is smaller than the diameter of the outlet of the diverging pipe; the inlet of the diverging pipe is in communication with the air outlet of the shell; the diverging pipe is spiral, the inlet of the diverging pipe is located at the center of the spiral, and the outlet of the diverging pipe is located out of the spiral; and the airflow discharged from the air outlet of the shell enters the spiral diverging pipe and continues to flow along the diverging pipe. The spiral metal dust collecting device invention allows the speed of the air flow carrying the metal dust to quickly and smoothly slow down, and the metal dust settles to the bottom of the spiral diverging pipe; and spiral metal dust collecting device has the advantages of smallsize, simple structure and convenient cleaning.

Description

technical field [0001] The invention relates to the technical field of dust collection, in particular to a spiral metal dust collection device. Background technique [0002] Existing industrial metal dust collection device is made up of three parts of dust suction device, conveying pipeline, dust removal device. The dust collection device only has the function of sucking gas, and does not have the ability to remove dust. The gas with high dust content flows through the conveying pipeline and is purified and removed after reaching the dust removal device. The above-mentioned transportation pipelines are narrow and small, and the density of metal dust is high, which is prone to explosion, which in turn leads to secondary explosions in the production workshop, which is more harmful than ordinary dust. The above-mentioned dust collector has defects such as complex structure, large volume, and potential safety hazards. Contents of the invention [0003] Aiming at the deficie...
