    Abstract: A temperature-controlled tramp metal separation assembly includes a core rod and a magnetic set. The core rod is made of non-magnetic materials and includes a chamber, a first end with an air inlet, and a second end with an air outlet. The magnetic set includes a plurality of magnetic members and a plurality of spacers respectively disposed between the two adjacent magnetic members. The magnetic set is nested in the chamber in a way that an air path is formed therein so that an external cooling air flow can be introduced from the air inlet, and then discharged from the air outlet via the air path. Thus, the operating temperature of the tramp metal separating process can be maintained at an acceptable level, preventing the magnetic force of the magnet set from being reduced.

  • Patent number: 11344828
    Abstract: A drilling mud remediation and drilling cutting treatment device and method. There are three main components: a vacuum liquid solid separator; a pelletizer; and an induction furnace. The liquid solid separator has a seamless filter belt configured to carry a mixture of liquids and solids over a vacuum. A slurry comprised of drilling mud and cuttings is deposited on the filter belt. An applicator ensures that the slurry is deposited evenly across the entire filter belt at a uniform thickness. The vacuum removes most of the liquids for further treatment and reuse. The solids are transferred to a pelletizer which compacts them into relatively uniform pellets while removing much residual liquid. The pelletized cuttings are then passed through an induction furnace, which removes any residual liquids, renderings the cuttings safe for disposal.

  • Patent number: 9555419
    Abstract: The present invention is directed to films that are deposited with foamable inks or coatings. One purpose is to facilitate their separation for recycling purposes. The films are particularly useful as packaging labels. The inks/coatings are designed so that foaming is activated when the film is in the hot-wash stage of a typical recycle process. This provides added buoyancy to the film allowing it to float to the surface and be removed, thereby significantly improving the efficiency of the recycle process. A feature of the invention is that, prior to this hot wash, the inks/coatings remain substantially unfoamed and thereby do not negatively affect the aesthetics of labeled package. The foamable inks/coatings can be used with any type of film.
