Description

TECHNICAL FIELD

[0001] The utility model belongs to dust removal machine technical field, and specifically is a modified engineering plastics particle dust removal machine. BACKGROUND

[0002] Modified engineering plastics are widely used in the fields of automobile, electronics, household appliances and the like, and its production process will produce dust, which not only pollutes the environment, but also may pose a threat to the health of workers, and even form a combustible dust and air mixture, causing an explosion. Therefore, in the production of modified engineering plastics, a cyclone dust collector is used to absorb the dust generated in the production process. The cyclone dust collector separates solid particles from the airflow by using the centrifugal force of the rotating airflow. The dust-containing airflow enters the cyclone dust collector through the inlet pipe and starts rotating inside the device. The airflow forms a vortex-like rotating motion inside the cyclone dust collector. This rotating motion generates a strong centrifugal force. Under the action of the centrifugal force, the dust particles are thrown towards the wall of the device and separated from the airflow, and move downward along the wall, finally falling into the hopper at the bottom. The purified airflow continues to rotate inside the cyclone dust collector and is finally discharged from the top outlet pipe, completing the dust removal process.

[0003] In the prior art, some particles that are not thrown by the centrifugal force towards the inner wall of the cylinder will be discharged outward from the upper pipe and the discharge pipe. The separated dust is again lifted into the upper pipe and the discharge pipe during the falling process due to airflow disturbance. This reduces the dust separation effect and increases the use cost of subsequent more refined dust removal equipment for further purification of the dust that has not been completely purified. Therefore, we propose a modified engineering plastics particle dust removal machine. UTILITY MODEL CONTENTS
