Abstract

A dust recovering device essentially comprises: a suction unit and a centrifugal unit. A blower in the suction unit directly sucks dusts into the centrifugal cylinder of the centrifugal unit enabling the dusts to enter the air current in the centrifugal unit. A cyclone generator generates a strong cyclone which uses its centrifugal force to separate the dusts from the air current. The separated dusts fall into a dust collection duct along the wall of the centrifugal cylinder, thereby effectively recovering the dusts such that the dusts will not be discharged in the air with the airstream.

^ 7596 —-—-— V. Description of the invention (1) The present invention "concentrates by suction, which is mainly the dust that is precipitated through the centrifugal force generated by the powerful cyclone in the centrifugal unit. Chips and powder are scattered in the flow, it is possible that the human body is extremely scarce, and some parts of the scene cannot be inhaled. Inhalation of air chips can be aerobic. The dust of ordinary woodcutters is full of air, which is caused by suction. In view of this, it will be scattered in the air, and the capacity of the unit can not be used. What's more, the dust returns to the dust exhaust fan for its airflow, and it is thrown away. 'And its work into dust damage.' Generally 4 in the so-called chip refilling, the general custom chip pre-setting space is effectively a volume collection device not produced by Feiyuan, even by mixing and mixing with the dust of the heart tube. The dust of the field or its equipment is mixed in the place, but the sense is not "designed to provide an air stream that can effectively recover the dust scattered in the air, and bring the dust into the cyclone generator in the centrifuge tube. The dust in the airflow is separated by the cyclonic phase, guided by the wall of the airflow analysis cylinder, and dropped into the dust collection tank, and then discharged into the air with the airflow. In the process of cutting and grinding the processing place, large dust will be generated due to its small size and will easily follow the dust in the air, so that it is suitable in the workplace, and even accumulates dust for a long time to the device; a gravity produces a spin Produced by, the people who cut the airflow with a moderate amount of volume are all created into a vacuuming device in a woodworking workshop or a cutting and grinding processing place, so as to suck the work to a suitable container by the vacuuming device In order to purify the air in the workplace, it should be shaved. The dust extraction device uses a filter screen to isolate the barrier, and then directly cuts it down. So when the scraps it collects are too small, the net will be blocked and the airflow will be discharged to the airspace again. For fine dust.
