Description

The invention relates to foundry and is intended for drying and heating of buckets of various capacities in steel and iron foundries of the engineering industry.

The purpose of the invention is to increase safety and increase the possibility of application.

FIG. 1 schematically shows a device for heat treatment of casting ladles; in fig. 2 - the same, top view; in fig. 3 - the same in the working position.

The device comprises a frame 1, on which a gas-burning device 2 is installed, guides nozzles 3, a suction system 4, consisting of an annular collector 5, a vertical suction box 6 in which a heat-exchanging unit 7 is installed, and a suction fan 8, connected by the discharge duct 9 with the guide nozzles 3, the carriage 10 with the stand 11 for the bucket 12, the lifting mechanism 13, the latches 14 and the blower fan 15.

The device works as follows.

The bucket 12 is mounted by the crane on the trolley 10 in the stand 11, with the clamps 14 the bucket 12 is rigidly fixed in the stand 11. The trolley 10 with the bucket 12 mounted on it enters inside the frame 1 and stops in such a way that the axis of the gas burner device coincides with the axis of the bucket 12 By means of a lifting mechanism 13, a stand 11 with a bucket 12 rises and presses against an annular manifold 5, the latter being designed so that with different bucket necks, the contact occurs along the lower edge of the annular collector 5. ogorelochnoe device 2 is turned on the blow fan 15 and the suction fan 8. The products of combustion exiting from the high

speed from the gas burner device 2 and diluted to the required temperature with flue gases from the guide nozzles 3, rush to the bottom of the bucket 12 and

then, due to the action of the suction ring collector 5, the walls of the bucket 12 rush upward. Thus, uniform heating of the bottom and walls of the bucket 12 is achieved.

Next, the flue gases pass through the vertical suction box b, while heating in the heat exchange unit 7, the air blown by the blowing fan 15 into the gas burner device 2. Ch. Gases that give up some of their heat to air

 for combustion, enter the suction zentil torus 8, then are directed by the air duct 9 to the injection nozzles 3 and a part is emitted into the atmosphere.

After drying or heating of the bucket 12 by the lifting mechanism 13, the stand 11 is lowered onto the carriage 10 and then rolled out of the unit. The heated ladle 12 is delivered by the crane for metal casting, and the new ladle is placed on the trolley 10, and the cycle is repeated again.
