TECHNICAL FIELD
[0001] The utility model relates to dust treatment device technical field especially, relates to a kind of adjustable wind speed's cyclone dust collection integrated device. BACKGROUND
[0002] In many fields of industrial production, such as mining, metallurgical smelting, cement manufacturing, machining, dust emission is a long-term and severe environmental challenge, and also seriously threatens the service life of production equipment and the health of operating personnel. As a widely used dust removal equipment, cyclone dust collection integrated device uses the centrifugal force generated by rotating airflow to separate dust from the airflow. Due to its simple structure, low operating cost, easy maintenance and other advantages, it plays an important role in industrial dust removal. Existing adjustable wind speed mostly relies on simple valve control or motor speed regulation to achieve precise wind speed control. For example, during production, the yield and properties of materials may fluctuate, and the amount and particle size distribution of dust generated also change accordingly. At this time, the speed regulation mechanism adjusts the wind speed to achieve the best dust removal effect. In the cyclone dust removal process, the dust-containing airflow rotates at high speed in the cyclone drum, and the dust is thrown to the drum wall under the action of centrifugal force and slides down along the drum wall. The ash hopper is arranged below the cyclone drum and can collect the dust falling from the drum wall, preventing dust from accumulating randomly inside the device and affecting normal operation of the equipment. In actual use, the ash hopper is usually a single taper fixed structure, which is difficult to adapt to the accumulation characteristics of dust under different working conditions, and cannot adjust the volume space of the ash hopper according to the amount of dust accumulation, so that the dust can slide more smoothly to the ash discharge port. In view of the above reasons, the present application proposes a cyclone dust collection integrated device with adjustable wind speed that can adjust the volume of the ash hopper according to different amounts of dust.
