Abstract
The invention discloses dust collection equipment for dental model workshops and a dust collection method thereof. The dust collection method comprises the following steps of: running a suction fan arranged on a cabinet of the dust collection equipment to outwards extract air to form negative pressure airflow; adsorbing dust in a dust collection channel in a dental model workshop on to the outer side surface of a bag dust filter along with the airflow; and starting a backwash valve positioned on one side on the inner surface of the bag dust filter to communicate with high pressure air to form positive pressure airflow for impacting the bag dust filter so as to make the dust adsorbed on the outer surface of the bag dust filter fall off. The technical means of out-bag dust accumulation is adopted, the short-time positive pressure airflow pulses reversely impact from the inner side of the bag dust filter toward the external through the backwash valve capable of being controlled to be opened, and the dust adsorbed on the outer surface of the bag dust filter under the action of negative pressure airflow for a long time falls off. Therefore, the cleaning of the bag dust filter can be completed at any time in the process of not stopping the machine, the good and stable dust collection effect of the dust collection equipment is improved and maintained, and the continuous working time of the dust collection equipment is prolonged.
