  • Patent number: 7140565
    Abstract: A scrap collector is comprised of a separator, a ventilating device, a chipping collecting container, a collecting bag, and a communicating pipe. The separator includes an air chamber, an inlet communicating with the air chamber, and a bottom hole communicating with the air chamber. The ventilating device is mounted on the separator and is provided with an outlet, generating an airflow flowing towards the outlet. The chipping collecting container is mounted under the separator, including an opening connected with the bottom hole of the separator. The collecting bag is mounted inside the chipping collecting container, including an opening in communication with the air chamber. An airtight room is defined between the chipping collecting container and the collecting bag. The communicating pipe has two ends respectively communicating with the air chamber and the room. Accordingly, the pressure inside the collecting bag and the room remains equal.
    Type: Grant

  • Publication number: 20050257507
    Abstract: An industrial scrap collector is comprised of a separator, a ventilating device, and a chipping-collecting container. The separator includes an air chamber formed inside, an inlet formed at a side thereof for communicating the air chamber with outside, a bottom hole formed at a bottom end thereof for communicating the air chamber with outside, a guide member spirally disposed on an inner periphery of the separator and having a top end and a bottom end respectively abutting the inlet and the bottom hole. The ventilating device includes an outlet, mounted on the separator for generating an airflow flowing towards the outlet. The chipping-collecting container is mounted under the separator, including an opening formed at a top end thereof for communicating with the bottom hole of the separator. Accordingly, the industrial scrap collector can collect the chippings and dust more efficiently.
