Abstract
The present invention provides a method for quantitatively and stably supplying fine powder and a system for implementing the method. In this invention, in a state in which at least part of the ultrasonic vibration gushing portion is in contact with the fine powder surface of the surface layer of the fine powder stored in the fine powder storage container, the powder inlet of the feed nozzle takes in the fine powder rising from the fine powder surface onto the ultrasonic vibration gushing portion through the passage region of the ultrasonic vibration gushing portion, together with the carrier gas, by ultrasonically vibrating at least part of the ultrasonic vibration gutting portion.
Claims20
A gas transfer type ultrasonic gushing fine powder quantitative feeding system comprising:
- a humidification chamber configured to humidify a carrier gas;
- and
- a gas transfer type ultrasonic gushing fine powder quantitative feeding device configured to quantitatively supply a mixed fluid of the carrier gas and fine powder to a fine powder using device, by supplying the carrier gas from the humidification chamber,
- wherein the gas transfer type ultrasonic gushing fine powder quantitative feeding device comprises:
- a fine powder storage container configured to store the fine powder;
- a housing configured to house the fine powder storage container in a gas-tight manner;
- a feed port configured to supply the carrier gas to the housing;
- a flow rate adjustment mechanism configured to adjust supply amount of the carrier gas to the housing;
- a feed nozzle configured to have a powder inlet for taking in the fine powder and the carrier gas, to accompany the fine powder with the carrier gas from the fine powder storage container, and to supply the fine powder and the carrier gas to the fine powder using device;
- a position detection sensor configured to detect a relative position between the feed nozzle and a fine powder surface of a surface layer of the fine powder stored in the fine powder storage container;
- an ultrasonic vibration gutting portion configured to be placed at least below the powder inlet of the feed nozzle and to be capable of ultrasonic vibration, the ultrasonic vibration gutting portion having a passage region through which the fine powder can pass in the vertical direction;
- a feed nozzle driving unit configured to vertically move the feed nozzle and the ultrasonic vibration gushing portion;
- and
- a humidity measurement sensor configured to measure a humidity in the housing, and
- wherein, in a state in which at least part of the ultrasonic vibration gushing portion is in contact with the fine powder surface of the surface layer of the fine powder stored in the fine powder storage container, the powder inlet of the feed nozzle takes in the fine powder rising from the fine powder surface onto the ultrasonic vibration gushing portion through the passage region of the ultrasonic vibration gushing portion, together with the carrier gas, by ultrasonically vibrating at least part of the ultrasonic vibration gutting portion.
