A fractionating device for separating powders in a chute
A recently filed patent (Publication Number: US20230194173A1) describes a fractionating device designed to separate a portion of a falling powder in a chute. The device includes a screw conveyor that passes through the chute, with a part of the casing opening inside the chute to receive the powder. Additionally, a collision separation member is mounted above the screw conveyor in the chute to prevent objects of a predetermined size or larger from falling directly onto the screw conveyor.
In one embodiment, the end of the discharging port side of the screw conveyor is positioned above the other end, and the rotation shaft of the screw conveyor has an inclination angle of 5° or more and 20° or less with respect to a horizontal plane. This configuration helps facilitate the fractionation process.
The fractionating device may also include a guide member to direct the powder falling in the chute towards the opening of the screw conveyor, enhancing the efficiency of the fractionation process.
Furthermore, the rotation speed of the screw conveyor's rotation shaft is variable, allowing for flexibility in controlling the fractionation process.
To ensure the efficient operation of the device, a cooling water passage is formed in the rotation shaft of the screw conveyor. This passage allows for the circulation of cooling water, which is supplied from outside the chute, to prevent overheating during operation.
Overall, the patent describes a fractionating device that utilizes a screw conveyor and a collision separation member to separate a portion of a falling powder in a chute. The device offers various features, such as adjustable rotation speed, cooling water circulation, and a guide member, to enhance the efficiency and effectiveness of the fractionation process.
