Description

Centrifuge structure capable of filtering gas

Technical Field

The utility model relates to a gas filtering device technical field, concretely relates to filterable gaseous centrifuge structure.

Background

At present, with the development of science and technology, the living standard of people is improved, and the living range of people is continuously expanded. Many forests are developed into houses, and the green area is gradually reduced, so that the quality of the air is gradually reduced. In order to not affect the living health of people, people develop an air centrifuge to filter and sterilize air, thereby improving the air quality. However, in the conventional centrifugal machine, rows of circular holes are usually formed on one side of the inner wall of the centrifugal chamber, the diameter of each circular hole is more than 10mm, and the holes are formed on one side, which is not in accordance with the aerodynamic force principle, so that the rotor rotating at a high speed deviates from the center of force due to the fact that airflow flows to one side. And because the opening is too large, the falling objects in the centrifugal chamber or broken glass centrifugal tube fragments are easily thrown out of the cavity. Meanwhile, because the air exhaust hole directly faces to the cavity of the shell, the design can lead the noise generated by the high-speed rotation of the rotor in the centrifugal process to be directly exhausted out of the machine along with the air flow; and the air outlet with the overlarge diameter is not blocked, and the falling objects in the centrifugal chamber or fragments of the glass centrifugal tube which are crushed by overlarge stress in the work can be directly driven by the cyclone rotating at high speed to fly out of the shell, so that the device is very dangerous.
