Description

Technical Field

[0001] The utility model relates to the technical field of powder coating production equipment, in particular to a cyclone separator in powder making equipment. Background Art

[0002] Cyclone separator is a kind of equipment used for separation of gas-solid system or liquid-solid system. The main function of cyclone separator is to remove solid particles and liquid droplets carried in the conveying gas as much as possible to achieve gas-solid-liquid separation to ensure the normal operation of pipelines and equipment.

[0003] Currently common cyclone separators use the centrifugal force generated by the rotation of gas containing solid particles to separate the particles from the airflow. However, this type of cyclone separator has a poor wind unloading effect when the gas enters, and there is still impact wind when the particles fall, resulting in poor separation effect. At the same time, the separated dust needs to be manually opened in the ash hopper for cleaning. This method is not suitable for occasions with a large amount of dust. Utility Model Content

[0022] Working principle: When used for the first time, the gas containing solid particles or liquid droplets is transported to the inner wall of the cyclone separator body 1 through the air inlet pipe 2, and the gas containing solid particles or liquid droplets is caused to rotate inside through the guide blades 3 and the spiral blades 6. Due to the centrifugal force generated by the rotation, the solid particles or liquid droplets with greater inertia are thrown to the inner wall of the cyclone separator body 1 and move downward along the inner wall, while the clean gas rises from the through hole in the center of the spiral blade 6 and is discharged through the air outlet pipe 7. At the same time, the filter screen 10 facilitates further filtering of the gas. When cleaning the dust in the collection bucket 4, the discharge valve of the collection bucket 4 can be opened, and the motor 501 output shaft 502 can be started to drive the connecting rod 503 to rotate. The rotation of the connecting rod 503 drives the scraper 504 to clean the dust remaining on the inner wall of the collection bucket 4.
