When cleaning magneto-susceptible impurities, the medium through the same-mentioned perforated partition enters the enlarged segment zone 7 and from there, through the pipe 8, is led out of the device. The most expedient approach is to make a drop from the rod elements forming the packages 9 (Fig. 2). In this case, the core elements can have, for example, either a circular 10 (Fig. 4) or an eloboid-like 11 (Fig. 6) section, and the rod elements themselves are spring-loaded in a special way by springs 12 located on the guides 13. The rod elements are driven in the contact or disconnected condition with the help of the device (fig. 8 and 9), consisting of the pusher 14, the ends of which are brought out to the outside through the hydraulic seal 15 and the housing cover 1b. By means of the cam mechanism 17, the pushers 14, bring the rod elements to the required Q position. A device for separating core elements is shown in FIG. 8. Embodiments of the nozzle are rod elements of various configurations (Fig. 11), for example, star-shaped 18, 25 polygonal 19 or tubular 20. A variant of the nozzle of the rod elements is a zigzag 21 shape package (Fig. 12). In the case of core elements with the possibility of their rotation and magnetic force 30 orientation, they are performed (Fig. 13) with an eccentric axis of rotation 22, while the direction of the magnetic flux 23 generated by the magnetizing system must not coincide with the direction 24 of the force

The high gradient magnetic filter precipitator operates as follows. The medium to be cleaned through nozzle 2 is fed into the inlet segment zone 3, from where it passes through perforated partition 4 Q perpendicular to the axis of the filter housing to the cleaning zone filled with a nozzle made of rod elements 5 that are also located perpendicular to the axis of the filter housing. Thus, the direction of movement of the fluid being cleaned 45 coincides with the axial suppression of the core elements. Since the perforation of the partition 4 is made with an increase in the area of the holes as they are removed from the nozzle 2, the cleaned liquid is distributed evenly throughout the entire volume of the stem. The core elements that fill the cleaning zone form an ordered structure in the form of a parallel arrangement of -. packages, and packages can have in cross section both the shape of a chain, and the shape of zigzags. With the help of a solenoid coil b, located around the filter housing 1, a magnetic field is created in the cleaning zone, which has a direction that does not coincide with six

Q 5 0.

conduit with housing axis. Since the rod elements are located across this field, they do not bypass it and in the zones of the lines of contact of the rod elements with each other a magnetic field of an increased gradient is formed. In the vicinity of these lines, magneto-susceptible particles present in the liquid are deposited on the surface of the core elements. Further, the purified liquid, having passed through the said cleaning zone and another perforated partition 4, enters the exit segment zone 7, from where it is removed from the device through the pipe 8.

The precipitator works as follows. First of all, the electric current that supplies the magnetizing cathode 6 is turned off. However, despite this, due to the residual magnetization of the core elements in the lines of their contact with each other, a significant high-gradient magnetic field continues to exist that does not allow the nozzle to be regenerated properly. Therefore, besides turning off the electric current, it is also necessary to break the indicated contact lines. For this purpose, the rod elements 10, spring-loaded by means of springs 12 arranged in the slots provided for their installation, have the possibility of free movement along the guides 13. The movement of the rod-shaped elements is carried out by the device for their periodic separation as follows. Through the cover 16 of the filter housing using the gland seal 15, the plunger 14 is wound inside the housing. By moving the cam mechanism 17 while rotating the cam mechanism 17, the plunger, overcoming the resistance of the springs 12, brings the rod elements closer to their mutual contact during the working cycle. During regeneration by rotation of the cam mechanism 17, the pushers move to the upper position and the rod elements 11 due to the elastic properties of the springs 12 are separated.

Packages of core elements can be different, including a linear or zigzag shape. The shape of the core elements themselves can also be different, for example, gutter-like 11, star-shaped 18, polygonal 19, tubular

20 et al.

The regenerated nozzle can also be made of rod elements with an eccentrically located longitudinal axis 22 of rotation. In this case, the axis of the filter housing, and, consequently, the direction of the magnetic flux 23 should be directed at a certain angle to the force of gravity 24. Such a nozzle works as follows. Under the action of a magnetic field formed by a magnetizing roller 6, and having a direction 23

magnetic force orientation and rotation of the rod elements occurs, as a result of which they are attracted to each other before mutual contact and form
