    1, the floating particles of the inclusions, the slag, are retained by the partition 12.: The passage through the filtering seed 9, the metal is cleared of non-metallic inclusions and removed through the opening 6. The presence of the partition 12 reduces the dimensions of the device. The location of the filter element 9
    vertically, making it circular, the presence of guides 15 on the outside of the chamber and the corresponding pins 16 in the partitions 7, 12 provides improved service by facilitating the change of filter elements 9. This also reduces the size of the device, 3 s. f-ly, 3 ill.
    The invention relates to metallurgy, in particular to devices for the refining of molten metals: and alloys, mainly aluminum; out, filter
    The aim of the invention is to improve the maintenance and size reduction of the device.
     FIG. 1 shows the device, a common B1-Shch | in fig. 2, 3 - the same, vertical longitudinal section. .
    A device for filtering molten metals and alloys contains a filter chamber 1, made in the form of a steel casing 2 with a tag,
    insulated 3 and resistant to
    molten metal lining 4, for example, from a ceramic material
    In the end wall of chamber 1, it is completed. inlet 5; h; l expanded metal alla ea. in the opposite end wall, there is an outlet opening 6; In chamber 1, a transverse partition 7 is installed in the form of a plate made of a material resistant to molten metal and a carrier part 8. In the partition 7 there is a filtering element 9 made of ceramic foam with beveled edge "Element 9 is sealed in the partition 7 with impingement material 10.
    The partition 7 is provided with a seal 115 located at its periphery to seal between n | 1v and the wall of chamber 1,
    In the chamber between, the inlet 5 and the partition 7 there is an additional continuous non-income. Up to the bottom of the partition 12 with the carrier part 13. The partition 12 is installed with the possibility of changing the distance to the bottom of chamber 1, and in the gap between the wall of the chamber 1 and bulkhead

    12 seals of material 14..
    On the outer side of the chamber 1 there are paired guides 15., and on the supporting parts 8 and 13 of the partitions 7 and 12 there are corresponding pins 16, so that the position of the partitions 7 and 12 is fixed by the guides 15.
    The number of pairs of guides 15 should not be less than two. For installation. Barriers 7 and 12. It is possible to use a larger number of barriers 7 (with filter elements 9). In this case, the number of pairs of guides 15 (Fig. 3) increases accordingly. .
    On the bearing parts 8 and 13 of the partitions 7 and 12 are fixed loops 17 for gripping the partitions 7 and a lifting mechanism (not shown).
    The device works as follows.
    The filter element 9 together with the partition 7 is preheated before installation into the chamber 1 (this is not a necessary measure, but it is preferable to use it, since in this case the heat loss in the metal decreases, the operating conditions of the filter element 9 are simplified).
    The molten metal through the inlet with the hole 5 enters the chamber 1. The metal flow by the partition 12 is directed to the bottom of the chamber 1. Particles of inclusions, slag, etc. retained on the metal surface by a partition 12, they are periodically removed-.
    The metal, the passage through the filter element 9, is freed from non-metallic inclusions and is removed from the chamber 1 through the openings 6.
    The partition 6 is installed in the central guides 1.5. If the filter element 9 needs to be changed during operation, then
