Because the dust in the gas will adhere to the animal fan blades. It is bound to hinder the airflow, which will reduce the air volume of the livestock fan, reduce the efficiency, or cause excessive vibration due to uneven attachment and attachment. The livestock fan manufacturer pointed out its treatment measures:
   1) Select a blade form that is difficult to attach dust, such as a backward blade.
   2) Take measures to remove the attachments.
   The methods for removing the attached matter are as follows:
   1) Wash regularly and intermittently with water.
   2) The mechanical removal device can partially remove the attachments.
   3) By means of hot air and cold wind, the temperature difference is formed.
   4) A method of spraying powder granules.
   In short, in today's energy-saving era, it is valuable to make a long-term operation under the high efficiency conditions of Qingdao animal husbandry fans.
