A magnetic filter is disclosed suitable for use in large heating and/or cooling systems, for example heating systems using pipework between 2 inch bore and 4 inch bore. The magnetic filter includes a separation chamber in the form of a pipe, and externally-mounted magnetic 5 assemblies which are movable from a position close to the pipe to a position spaced from the pipe. The magnetic assemblies are pivotally mounted to the pipe via a framework.

The application provides an apparatus for removing ferrous particles from an oil or gas process liquid or slurry and a method of use. The apparatus has a first inner cylindrical sheath and a second outer cylindrical sheath arranged concentrically on a longitudinal axis to create an annular volume. A helical screw flight on the first or second cylindrical sheaths extends across the annular volume, and a magnet assembly extends along the longitudinal axis, such that ferrous particles are attracted to a surface of the annular volume. The apparatus has an inlet a discharge outlet, and a ferrous particle collection location. The screw flight and the cylindrical sheath operable to rotate with respect to the magnet assembly to convey particles to the collection location. The apparatus includes a retaining surface to retain collected particles.

A drainage processing apparatus that processes drainage expelled from a scrubber apparatus is provided. The drainage processing apparatus includes: a magnetic powder adding unit that adds magnetic powders to the drainage; a transfer unit that transfers the drainage; and an adsorbing unit that: is provided in the transfer unit; adsorbs bound matter that is contained in the drainage and contains at least a process-target substance and the magnetic powders; and retains the bound matter in the transfer unit. In one example, the adsorbing unit is able to re-release adsorbed bound matter into the transfer unit. In one example, the adsorbing unit has a permanent magnet provided to be directly insertable into and removable from within the transfer unit, and the permanent magnet adsorbs the bound matter by being inserted into the transfer unit, and re-releases the bound matter into the transfer unit by being removed from within the transfer unit.

A purification system and method may include a container receiving portion, pump, and magnetic field generating element. The container receiving portion may be configured to receive and support a container containing a mixture. Magnetic beads may be added to the container for separating a target substance from a remainder of the mixture. The magnetic field generating element may be movable relative to the container receiving portion between a non-working position remote from the container receiving portion and a working position adjacent an outer periphery of the container receiving portion. In the working position, the magnetic field generating element may attract the magnetic beads and hold them firmly against an interior surface of the container. While the magnetic beads are immobilized by the magnetic field generating element, the pump may remove the mixture from the container, leaving behind the magnetic beads bound tightly but reversibly to the target substance.

The objective of the present disclosure is to provide a technique for reducing a quantity of magnetic particles remaining on a reaction vessel wall surface in a cleaning step for reducing, in a stepwise manner, an amount of a magnetic particle solution in the reaction vessel. The automated analysis device according to the present disclosure causes an agitating mechanism to operate in such a way that a magnetic substance remaining on the wall surface of the vessel in the previous cleaning step is captured by a cleaning solution in the next cleaning step (see FIG. 10).

An intelligent magnetic microfluidic concentrator employs a technique of feeding ores circumferentially and allowing tailings to overflow centrally upward. The intelligent magnetic microfluidic concentrator comprises a sorting system consisting of an ore feeding chute, an overflow chute, an overflow tank, a sorting tank, and a magnetic system, the overflow tank is disposed at an upper portion of the sorting tank, the ore feeding chute is disposed at the top of the overflow tank, the ore feeding chute feeds an ore slurry to the upper portion of the sorting tank circumferentially along an inner wall of the sorting tank, and the tailings overflow out upward from the overflow tank disposed centrally and located at the upper half portion of the sorting tank. A magnetic microfluidic concentrator and a complete set of beneficiation equipment are also provided.

An assembly and process for treating contaminated fluid. The assembly has a reactor including a tank with an internal weir, a low speed mechanical mixer, and means for delivering fluids to subsequent stages. A first stage has polymer make-up and coagulant feed units plus a dilution means which deliver modified contaminated fluid to a second stage with a low impact feed pump to preserve flocculant integrity. In a third stage, first sub-assemblies of self-cleaning magnetic shuttles capture at least some of the magnetic flocculant that escapes in the clarified effluent. In a fourth stage, second magnetic drum-type sub-assemblies separate magnetite particles from the flocculant, return the magnetite to the reactor, and send the non-magnetic solids to a fifth stagedewatering. This stage has a receptor for accommodating solids that are optionally treated with a coagulant and flocculant to produce solids to be transported to a landfill.

Apparatuses and methods for removing magnetic particles from suspensions are described. One embodiment of the apparatus is called a magnetic needle.

A magnetic filter assembly 1 is described which is suitable for incorporating into a fluid system such that a process fluid flows through the filter to remove ferromagnetic particles in the fluid. The filter assembly 1 comprises a housing 2 having a flow chamber. The housing also comprises one or more elongate hollow sleeves 10 extending into the flow chamber such that, in use, an exterior surface of each sleeve 10 is exposed to the process flow and an interior surface of each sleeve 10 is sealed from the process flow. Each sleeve 10 has an opening via which the interior surface of the sleeve is open or openable to the environment whilst remaining sealed from the process flow. Each sleeve has received in it a magnet 12, the magnet being removable from the sleeve via the opening. In this way, cleaning of the filter by removal of the magnets is facilitated, without exposing the process flow.

Disclosed herein are embodiments of a polymer-functionalized particle for using in isolating and extracting solutes, such as rare earth metals, lithium, and the like. The polymer-functionalized particles exhibit strong resistance to agglomeration and degradation even in high ionic strength and/or temperature environments. A post-particle synthesis method for making the polymer-functionalized particle is disclosed, along with a magnetic separation device and that can be used in system embodiments to facilitate use and regeneration of the polymer-functionalized particles in solute extraction.
