Description

SP

11 The invention relates to metallurgy, more specifically to installations for the selection and sorting of refractory lining after its removal from metallurgical units. The purpose of the invention is to improve the quality of the separation of the refractory material. FIG. 1 given line, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - view B on fgg. 2. The line for the selection of the lining of the metallurgical aggregates consists of bunkers1 arranged along the technological process with gratings 2, above which the railway track 3 for railroad cars 4 is laid. A magnetic crane 5 is installed above the bunkers, vibrating feeders 6 are under the bunkers, and at the end of them - conveyor 7, under which the screen 8 is fixed and discharge conveyor 9. Above the discharge conveyor during its movement a monorail 10 is mounted with a metal divider fixed on it, consisting of two paired electrically their hoists 11 and electromagnets 12. They are fixed above the conveyor line, forming the centering position of the refractory brick along the conveyor axis as it moves the material centering centers 13, guide plows 14 and dumps 15. Under the conveyor there is a screen, metal separator located in the zone, the hoppers and the end drum of the conveyor 9 are fitted with funnels 16 connected to the shipping bins 17. These bunkers are equipped with valves and their drives 19. A railway line 20 is located under the valves of the bins 17. eremescheni of carriages mounted therein for transport spire 21, the channel 22, the end of which is connected with the carriage 23. The second end of the rope is fixed on the opposite sides of the car and roll through the bypass 24 is connected with the transport spire. The resetter 15 (FIGS. 2 and 3) consists of a pneumatic cylinder 25 mounted on a bearing support 26, A stop 27 is installed at the cylinder rod, a blade 29 is pivotally suspended from the axis of the rod 28, and the rollers 31 are fixed at the ends of the axis in the guides 30. 4 Lini works as follows. The refractory lining in the form of scrap in the cars 4 is served by rail track 3 and loaded through the grids 2 into the bunker 1. Large pieces that have not passed through the grids are removed by the magneto-grab crane 5 and transferred to crushing. After the mechanisms of the lines are turned on by vibrating feeders 6, material from the bins is fed to. conveyor 7. From the conveyor, refractory scrap enters the screen 8, from which a large (pit) fraction enters the conveyor 9, and fine dust and dust through the raven, KU 16 - into the shipping bunker 17. The coarse fraction, moving along the conveyor 9, passes Scrap and other magnetic inclusions are periodically removed from the area of electromagnets and periodically one of the magnets unloads them into the funnels 16 and from them into the bunker 17, and the second is at this time under the flow of material moving along the conveyor belt 9, then they change in places. Purified refractory scrap located on a conveyor belt enters zone I of material centering points 13, which shift it to the axis of the conveyor belt. After that, the process of selecting the lining (sorting) by its type, for example, separation of silica (aluminous), aluminosilicate (chamotte), magnesian-spinelide (magnesian), chromite-periclase (chromo magnesite), etc., occurs. the refractories pass by the diverters 15, the Operator, by switching on the corresponding pneumatic cylinder 25, the diverter 15 delivers the rod with the shovel 29 forward and the latter moves the piece of refractory brick to the guide plow 14, which A brick is in the funnel 16, and by yay in one of the shipping bins 17. The DPA of each of the bins listed has its own diverter and its own bunker. The remaining material on the tape comes from the end drum 9 to the last bin 17 (leftmost). The design of the dumper, due to the presence of the stop 27, the pivotally suspended blade 29, mounted on the guides 30 on the rollers 31, makes it possible to drop the fire resistance and

returning is lifted, passes loose pieces of refractories passing through the tape. Refractory scrap, metal inclusions and fines collected in bins by types using gates 18 with drives 19 are periodically loaded into wagon 23 and sent for recycling.

To move the car under the bunkers 17 use transport

spire 21, channels 22 and bypass roller 24,

The present invention completely eliminates manual operations, allows 5 to create a continuous lining selection process, to select and sort according to the quality of waste, it makes it possible to extract metal inclusions from the lining and dispose of them.
