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, 01D 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 tubes of a nonmagnetic material, along which are placed without touching the rods diamond-shaped cross-section, inside the tubes 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 non-magnetic element is found in the form of a plunger, spherical tip which is in contact 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, with all magnitude established between themselves and with diamond-shaped rods with a clearance of not more than three times the thickness of the thin liquid layer near the surface of the tubes; an outlet opening 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 tray.

The invention is illustrated by figures which depict: 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 is a transverse section of the device; figure 4 - distribution of the flow of liquid to magnitudes in the cleaning mode; figure 5 - elements of the s inside of magnitudo, figure 6 is a variant of the 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 located preferably above the axis of magnitudo that helps organizations streams flowing tube 6. 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. Magnitude installed with a gap between themselves and with diamond-shaped rods 11 between magnetovolume. The rods 11 diamond-shaped cross-section prevent splashing and lateral mixing of fluid flows and contribute to the formation of an edge of a thin liquid layer at the surface of the vertical column tube 6. Pass all of purifying water flow in these t the nkiye layers is the best conditions for the deposition of magnetic particles on the strings 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 in these conditions, without lateral mixing flows. The gap will be determined approximately 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 12 with the magnetic heads 13, the compensating strip 14 and the stub 15 with the outer spherical surface. Non-magnetic elements are in the form of a plunger 8, the spherical lugs which contact plugs 15 capsules. Extreme non-magnetic elements in the tubes interact with the piston rod 16 of the hydraulic cylinder 17.

The hole 18 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 19, kinematically connected with the rod of hydrocele the DRA 20, and the output fluid in the cleaning mode and washing is carried out in two trays 21 and 22, 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. Due to the location of slot above the axes of magnitudo liquid in a thin layer which surrounds the tube 6 of each column of magnitudo from the top to the bottom rows. The rods 11 diamond-shaped cross-section contribute to the formation of a thin liquid layer around magnitudo 6 and prevent mixing of fluid between the rows of magnitudo. Magnetic particles in a thin layer effectively deposited on strings and cleaning liquid from the magnetic particles. The purified liquid is routed through the hole 18 in the lower part of the vessel, which is equipped with an on / off valve 19, the tray for the purified liquid 21.

In the cleaning mode strings in the working area 4 are non-magnetic elements - pushers 8, which by means of the hydraulic cylinder 17 is transferred is magnitnye 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 19 by means of the hydraulic cylinder 20 is moved into the second position, directing the suspension of the magnetic sludge in the appropriate tray 22.

Switch between cleaning and rinsing is determined by operational need, for example, is determined visually on the size of the deposited layer of 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 around magnitudo. Per performance unit dimensions devices become smaller and structurally simplified in comparison with the prototype. At the same time, compactness and ease of installation and operation permit to manufacture the device, consisting of several standard modules, as shown in figure 6.
