The invention relates to the purification process fluids, lubricating fluids (coolant) and can be used at the enterprises of metallurgy and Metalworking industry, as well as for purification of natural waters.

A device according to the patent of Russian Federation №2372135, B01D 35/36 for extracting magnetic particles from a liquid medium in which the device is made in the form of an elongated parallelepiped and is fitted with inserts that separates the internal volume of the housing for the working and non-working zone, and the magnetic system is made in the form of pipes placed in them permanent ring magnets, alternating with beads that make up the local magnetic system with length equal to the length of the working zone, and the non-magnetic inserts, also alternating with inserts, this provided the ability to move inside the tube magnets, non-magnetic inserts and balls through the actuator on the value equal to the length of the working zone. Straight sections of pipe are interconnected radial taps so that the end of the first straight pipe is connected with the beginning of the next, thus forming a continuous single loop, starting and ending line sections that communicate with the drives. The inner pipe is filled with liquid filler.

Radius taps connected balls and magnitnye inserts, and the inside of the pipe filled with liquid filler with a low coefficient of friction.

The known device has an increased size due to the presence of radius bends and insufficient leaching efficiency.

Closest to the claimed device according to the technical nature of a device according to the patent of Russian Federation №2400305, IPC VS 1/00. Device cleaning liquid from the magnetic inclusions contains a container with a nozzle and a vertical perforated walls through which fluid flow along the magnetic tubes, and a uniform distribution over the entire height of the tank. The pipes of the tank is used to supply the purified fluid and withdrawing a purified, for the periodic supply of wash water. The device also includes a horizontal magnitude made in the form of a tube of non-magnetic material, inside which is placed an unbroken chain of magnetic and non-magnetic elements, separating Manitowoc on alternating work and non-work zones. Magnetic items are a capsule that includes a stub with an outer spherical surface, non-magnetic disks, magnetic elements and the damping strip. Non-magnetic elements are in the form of a plunger with a spherical tip, resting in the capsules. Magnetic and non-magnetic elements share Manitowoc at the turn of the present work and non-work zones. Far outside the zone of magnitudo interact with the rod of the linear actuator periodic reciprocating movement.

The drawbacks are the complexity of the design of the baffles and nozzles for various purposes; increased dimensions per unit performance because of the relatively large distance between magnetovolume because of the horizontal flow and the need to reduce the hydraulic resistance to flow.

The technical problem of the invention is to increase the performance, reduce size and to reduce thereby the metal device with high quality cleaning fluid.

The problem is solved by the claimed device.

Device for cleaning liquid from the magnetic particles containing vessel with nozzles, at least one vertical partition separating capacity for working and non-working zone, horizontal magnitude made in the form of a tube of non-magnetic material, inside which is placed an unbroken chain of magnetic elements in the form of capsules containing a set of ring magnets with magnetic tips, compensating gaskets and plugs with the outer spherical surface, and a nonmagnetic elements in the form of the follower, spherical tips which kontakter the Ute with the caps of the capsules, extreme non-magnetic elements in the tubes made with the possibility of reciprocation by means of the piston rod of the hydraulic cylinder. In the inventive device in the upper part of the vessel is a horizontal perforated partition, below which is placed a horizontal partition with slotted holes located preferably above the axis of magnitudo located in a vertical plane under each other, and rows in the horizontal plane, and are installed between each other with a clearance of not more than three times the thickness of the thin liquid layer near the surface of the tubes, with tube magnitudo, located opposite each other in the same vertical plane, covered on two sides with polymer films, for example, polypropylene, converging on the vertical axis of the tubes in the gap between them, the hole in the bottom of the tank provided with means for distributing liquid in different trays, for example, a two-position valve, kinematically connected with the rod of the hydraulic cylinder, allowing the cleaned and the washing liquids in the respective two trays.

The invention is illustrated by the figures, which show: figure 1 is a longitudinal section of the device in the mode of cleaning fluid; figure 2 is a longitudinal section of the device in the cleaning mode; figure 3 - poperechnyy device; on the figure 4 - distribution of the flow of liquid to magnitudes in the cleaning mode; figure 5 - elements inside magnitudo, in figure 6 - option modular device for cleaning liquid.

Device for cleaning liquid from the magnetic particles has a reservoir 1 with an inlet pipe 2, the vertical wall 3 separating the internal volume of the tank in 4 working and non-business 5 zone. Horizontal magnitude made in the form of tubes 6 of nonmagnetic material, inside of which are magnetic elements made in the form of capsules 7, and non-magnetic elements in the form of the pusher 8. In the upper part of the vessel (figure 3) is a horizontal perforated leveling partition 9, below which is placed a horizontal partition 10 with slotted holes 11 located preferably above the axis of magnitudo that promotes the separation of the flow over each magnitudo two symmetric flow pressure and the formation of the threads 12, flowing tube 6 with a thin layer. Magnitude placed in a vertical plane under each other and rows in the horizontal plane so that the cross section (figure 3) conventionally form a rectangular grid. Tube 6 magnitudo, located opposite each other in the same vertical plane, covered on two sides with polymer films 13 and 14, the CX is maximise on the vertical axis of the tubes in the gap 15 between them. For layer film in the gap 15 thin layers 12 of the cleaned fluid smoothly and oriented to pass from the upper magnitude to the bottom. Magnitude installed with a certain small gap horizontally between them. The passage of the flow of the purified liquid in a thin layer around the tubes 6 creates the best conditions for the deposition of magnetic particles on the films 13 and 14 in place of the coverage of magnitudo in the cleaning mode. The size of the gap, for example 10 mm for water can be determined experimentally. The liquid in a thin layer should proceed smoothly, without breaks, as fast as possible to ensure a given quality treatment in these conditions, without lateral mixing flows. The gap can be expressed, for example, as three times the thickness of the thin liquid layer near the surface of the tubes. Increasing the gap would lead to an unjustified increase of the device, reducing the quality and cleaning performance due to the need to reduce the feed rate of the liquid to maintain laminarinase stream.

An unbroken chain of magnetic and non-magnetic elements inside the tubes 6 is identical to the prototype and forms in magnitude alternating work and non-work zone (figure 5). The capsule of the magnetic element includes an annular magnets 16 with the magnetic heads 17, the compensating strip 18 and the stub 19 from outside fericelli surface. Non-magnetic elements are in the form of a plunger 8, the spherical lugs which contact plugs 19 capsules. Extreme non-magnetic elements in the tubes interact with the piston rod of the hydraulic cylinder 20.

The hole 21 in the lower part of the vessel provided with means for distributing liquid in different trays. As an example, this can be a two-position valve 22, kinematically connected with the rod of the hydraulic cylinder 23, and the output fluid in the cleaning mode and washing is carried out in two trays 24 and 25, respectively, for treated liquid and washing liquid.

The device operates as follows.

In the cleaning mode strings in the working area 4 are magnetic elements - capsules 7. The treated fluid in the inlet pipe 2 is fed into the tank 1 passes through a horizontal perforated partition 9, distributing the liquid throughout the volume of the working area. Through the slotted holes of the horizontal partition 10, the liquid flows in horizontal magnitude 6. Thanks to the films 13 and 14, the total volume of liquid in a thin layer on the film smoothly without breaks to wrap around the tube 6 magnitudo from the top to the bottom row. The magnetic particles are in the area of the strongest near-surface magnetic fields. Magnetic particles in a thin layer effectively deposited on the films and on Westside cleaning liquid from the magnetic particles. The purified liquid is discharged through the opening 21 in the lower part of the vessel, which is equipped with an on / off valve 22 in the tray for purified liquid 24.

In the cleaning mode strings in the working area 4 are non-magnetic elements - pushers 8, which by means of the hydraulic cylinder 20 is transferred magnetic elements 7 outside of zone 5. In the working area 4 serves washing fluid (this can be including liquid), which washes out the sludge with the non-magnetic tubes 6. The valve 22 by means of hydraulic cylinder 23 is moved into the second position, directing the suspension of the magnetic sludge in the appropriate tray 25.

Switch between cleaning and rinsing is determined by operational need, for example, is determined visually by size sediment magnetic particles or cleaning time, etc.

Increase the performance of cleaning fluid and the high quality of cleaning is ensured by the fact that magnitude have a tight location, thus providing a high gradient magnetic field, almost all the liquid is held in the form of thin layers with higher speed in comparison with a prototype around magnitudo. On unit performance dimensions of the device significantly become smaller and structurally simplified in comparison with the prototype. At the same time, compactness the ü device and ease of installation and operation permit to manufacture the device, consisting of several standard modules, as shown in figure 6.

The device can be carried out under production conditions using known materials and equipment.
