A magnetite level monitoring device for a magnetic filter in a central heating system, the magnetic filter including a separation chamber, an inlet to the chamber and an outlet from the chamber, and a magnetic element disposed within the chamber for attracting magnetic particles and removing the magnetic particles from the system water as it flows through the chamber, and the monitoring device including: a housing for placing adjacent to the outside of the separation chamber; a magnetometer mounted to the housing; a magnetic field guide mounted to the housing, the magnetic field guide being disposed between the magnetometer and the outside of the separation chamber, when the housing is mounted to the separation chamber; and output means adapted to issue a notification when the output from the magnetometer exceeds a predetermined threshold.

A method of operating a magnetic selector is provided. The magnetic selector includes a housing including a floor having a floor surface, a magnet carrier disposed on an opposite side of the floor from the floor surface and having at least one magnet disposed thereon, the magnet carrier being moveable relative to the floor between a first state wherein the magnet carrier is adjacent the floor and a second state wherein the magnet carrier is spaced from the floor. The method includes disposing a container on the floor surface, moving the magnet carrier to the first state to apply a magnetic field to a fluid in the container, moving the magnet carrier to the second state from the first state to disengage the magnetic field from the container, and removing the container.

A magnet module used for producing a carbon nanotube dispersion liquid, comprising: a pipe portion having a first opening connected to a shearing module, and a second opening at both ends; and a magnet disposed in the pipe portion, wherein a medium liquid containing the carbon nanotube defibrated by the shearing module is supplied through the first opening, and after a ferromagnetic impurity attached to the carbon nanotube is attracted to the magnet and removed, the medium liquid is discharged from the second opening.

A workpiece processing assembly comprising including a media collection device that is adapted to receive used media from a media blasting chamber. A transport mechanism, coupled to the media collection device, transports used media to a media reclaim system. A first separation device is used to perform a filtering process on the used media to separate non-usable media from usable media. A second separation device is configured to apply a magnetic field to the usable media to create recycled media for use in the media blasting chamber.

A tramp metal removing device has a primary housing to define a product flow path for being passed by a stream of raw materials and a moving path. A secondary housing is connected to the primary housing. A plurality of drawer units are sequentially stacked on the primary housing and secondary housing. Each drawer unit has a frame, a plurality of magnetic members and a scraping assembly. The frame is coupled with the primary and secondary housings in a movable way. Each of magnetic members is secured on the frame and has a magnetic section and a non-magnetic section. The scraping assembly is coupled with the frame in a way that it is only moveable in the secondary housing for removing tramp metals of a stream of raw materials in a two-stage manner.

A pneumatically-operated magnetic separator captures magnetic contaminants from process fluids. Process fluids are used in many industrial operations for various purposes. The pneumatically-operated magnetic separator can include a housing wall, a first flange plate assembly, a second flange plate assembly, a main fluid passage, tubes, and shuttles. The first and second flange plate assemblies can each include a pair of flange plates. The tubes extend between the first and second flange plate assemblies, and the shuttles are situated in the tubes. Each of the shuttles includes one or more magnets. During use, the shuttles move longitudinally in the tubes in response to pneumatic actuation and de-actuation, per an example. Weldments attach the tubes and the first and second flange plate assemblies together.

An in-line fitment for connection of a filter to a pipe includes first and second fluid-carrying portions and a non-fluid-carrying spacer. Each fluid-carrying portion includes a socket for receiving an open end of a pipe and a connector for connection of the filter. A screw compression fitting is provided on each of the sockets of the first and second fluid-carrying portions for forming a sealed connection with the open ends of the pipe. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion for enabling movement of the fitment parallel to the pipe when engaged with one of the open ends of the pipe. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

Disclosed herein is a waste oil purification apparatus that purifies waste lubricating oil and waste oil at high speed by a precipitation induction method in a vacuum state and further completely removes metallic foreign materials, thereby improving the efficiency of the purification of waste oil. The waste oil purification apparatus may include a purifier configured to purify waste oil such as waste lubricating oil or general waste oil by a filtering method, and a separator configured to separate and remove foreign materials contained in the waste oil purified by the purifier.

A device for separating tramp metals from liquid raw materials includes a body unit, a holding unit, a magnetic unit, a rinsing unit, and a driving unit. The body unit includes a tank for feeding-in and feeding-out liquid raw materials. The holding unit is coupled to the tank and includes and a plurality of non-magnetic holders received in the tank. The magnetic unit is mounted on the tank and includes an enclosure haying a telescopic wall to be in a compressed or extended state. The rinsing unit is fixed on the interior of the tank to rinse the non-magnetic holders. The driving unit is coupled the tank and the magnetic unit for driving the magnet unit moving between a first and second positions. An assembly is assembled from the device. And a method is carried out by the device or the assembly.

A magnetic tool may be provided with a ditch magnet that may include end plates (or handles) having a mostly open architecture, and these end plates may be permanently affixed to the ends of the magnetic bar. Ferrous metal may pass through by urging captured ferrous metal from one end of the ditch magnet to the opposite end. The captured ferrous metal may be urged from one end of the ditch magnet bar to an opposite end using a composite, multi-component wiper. The wiper may remove captured ferrous metal safely and effectively from the ditch magnet bar.
