Abstract
The utility model discloses a dust collection device for a dental model workshop, which comprises a chassis, an exhaust fan and a dust filtering bag. A first clapboard is arranged in the chassis to divide the sealed space of the chassis into a first space and a second space which are isolated from each other up and down. The exhaust fan is positioned in the first space. A dust collection return air passage is positioned in the second space. The first clapboard is provided with a hollow-out hole. The dust filtering bag is positioned on the hole and extends into the second space to be arranged. A return impact valve is also arranged in the first space and is connected to a high pressure air source. Due to the adoption of the technical means of collecting dust outside the bag, reverse impact is carried out from the inside of the dust filtering bag to the outside by the return impact valve capable of being controlled to open through utilizing a positive pressure airflow pulse in a short time, so that dust adsorbed on the outer surface of the dust filtering bag by negative pressure airflow for a long time falls down; therefore, the cleaning work of the dust filtering bag can be completed without shutting down, the excellent and stable dust collection effect of the dust collection device is improved and kept, and the durable working time of the dust collection device is prolonged.
