The present invention is related to an intelligent and durable buried drainage pipe involving a method of separation and transmission. The intelligent and durable buried drainage pipe of the present invention includes an inner (11) and an outer (12) pipe. The outer pipe (12) is longer than the inner pipe (11); a permanent magnet (2) is installed on a section of the outer pipe (12) that is longer than the inner pipe (11). At least one electromagnet (3) is fixed at intervals from the permanent magnet (2); the energized electromagnet (3) can attract the permanent magnet (2) causing it to slide. The end of the electromagnet (3) facing the permanent magnet (2) is provided with a distance sensor (6), and the switch is turned on/off by the distance sensor (6). An elastic telescopic member (4) is arranged between the permanent magnet (2) and the electromagnet (3).

A device for capturing and releasing magnetically susceptible particles includes a housing and a retraction mechanism. A permanent axially magnetized cylindrical magnet is coupled to the retraction mechanism and a distal end of the magnet extends from a distal end of the housing. The retraction mechanism is configured to position the distal end of the magnet at one of three different predetermined distances from the distal end of the housing: retracted, protracted and hyper-protracted. A sleeve is provided over the housing distal end and when the magnet is in the protracted position, magnetically susceptible particles are gathered, when in the retracted position, magnetically susceptible particles are released and the sleeve is ejected when the magnet is positioned at a point between the protracted and the hyper-protracted position.

A self-cleaning magnetic filter for removing ferrous contaminates from a natural gas process stream including a housing through which the process stream follows for removing ferrous contaminates in the process stream by magnetic attraction with a plurality of magnetic bars that are removably disposed in a plurality of non-magnetic sleeves disposed within the housing. A recirculating washing solution is used to flush contaminates that adhere to the exterior surfaces of the non-magnetic sleeves and from the housing. A bag filter is used to remove contaminates from the washing solution to allow recycling the washing solution.

A tramp metal separation assembly comprises a housing, a core rod and a sleeve tube. The housing includes a first and second discharging areas and a feeding area. The core rod includes a first and second non-magnetic sections and a magnetic section. The core rod is mounted on the housing in a way that the first and second non-magnetic sections correspond respectively to the first and second discharging areas and the magnetic section corresponds to the feeding area. The sleeve tube includes a first and second portions. The sleeve tube is sleeved outside the core rod in a way that it is moveable between a first position, wherein the first portion corresponds to the magnetic section and the second portion corresponds to the second non-magnetic section, and a second position, wherein the first portion corresponds to the first non-magnetic section and the second portion corresponds to the magnetic section.

A magnetic separator for a liquid handling system includes a base unit having at least one receiver configured to receive a consumable, the at least one receiver being dimensioned to receive the consumable in a predefined location at least partially within the base unit. The magnetic separator further includes a magnet system located within the base unit proximate to the at least one receiver, the magnet system including a first separation magnet configured to perform separation of beads located within the consumable when the first magnet is located proximate to the consumable, and a movement system configured to move the first magnet in at least two directions in order to adapt to a shape of the consumable.

A magnetic separator includes a housing defining a product flow path, a drawer moveable between a first position and a second position, a magnet operatively connected to the drawer, the magnet positioned within the product flow path when in the first position and the magnet withdrawn from the flow path when in the second position, and a stripper plate frame attached to the housing. A stripper plate is fixed to the stripper plate frame that conforms with the magnet and through which the magnet passes as the drawer is moved between the first and second positions. An anti-rotation mechanism includes a slot that engages along a length of a shoulder such that. When the anti-rotation mechanism is positioned having the slot over the shoulder, the magnet is prevented from moving from the axially locked position. The shoulder extends beyond an outer surface of the anti-rotation mechanism.

Disclosed is a detection apparatus that transfers magnetic particles through a plurality of chambers in a cartridge which includes the plurality of chambers and a channel connecting between the plurality of chambers, and that causes the magnetic particles to carry a complex of a test substance and a labelling substance, to detect the test substance on the basis of the labelling substance in the complex. The detection apparatus includes: a rotation mechanism configured to rotate the cartridge about a rotation shaft; a magnet configured to collect the magnetic particles in the chambers; a movement mechanism configured to move the magnet in a direction different from a circumferential direction of a circle in which the rotation shaft is centered; a detector configured to detect the test substance; and a controller programmed to control the rotation mechanism and the movement mechanism so as to transfer the magnetic particles from one of the chambers to another one of the chambers.

A method and apparatus for continuous magnetic filtration of ferrous mill scale from liquid solution employs a tank for receipt of fluids laden with mill scale. A curvate trough within the tank receives a rotatable magnetic drum and establishes a channel therebetween. An air compressor and associated manifold generate bubbles within the tank and adjacent the rotatable magnetic drum. The mill scale attaches to the bubbles, which are attracted to the surface of the drum where the mill scale accumulates. The accumulation of mill scale particles is moved about the surface of the rotating drum by a scraper proximate the surface thereof. By moving the accumulated mill scale particles to regions of the rotating drum that are of a magnetic force insufficient to retain them upon the surface of the drum, the mill scale particles are removed and passed to a conveyor system.

A rotatable magnet cradle assembly that can be used to separate swarf from a flow of fluid is provided. The cradle of magnets can be rotated a certain amount about a rotational axis from an operational position to a cleaning position. The magnet cradle may include a tube extending between two brackets, a shaft to which the two brackets are attached, and a magnet bar extending through the tube. In the operational position, the magnet provides a magnetic field that attracts swarf to an outer surface of the tube. Once it is desired to clean the assembly, the shaft is rotated to move the two brackets and tube out of the fluid flow and to a position proximate a discharge location, where the magnet bar can be removed from the tube to release the swarf.

This invention relates to a device and method of using the device for purification that separates material of interest from contaminating materials using non-porous magnetic particles and single-use or disposable materials that come in contact with the material of interest. The process encompasses multiple cycles in a single batch to reduce the cost of magnetic particles. This method can be executed in a fully automated manner by a controller that manages different inputs and outputs of system hardware.
