SU90831A1 - Rod for removing rings in hot rotary kilns - Google Patents

Description

The subject of the invention is a rod for removing rings in hot rotary kilns, mounted on a trolley and introduced into the furnace by means of a winch.

The drawback of pull-out rods used for breaking the rings in hot rotary kilns is that they cannot break the outer rings, as well as the rings located in the high temperature zone.

A distinctive feature of the described rod is the fact that it consists of sliding links, and the end of the extreme link is bent at a right angle. In addition, a perforated pipeline is placed inside the rod for supplying cold water under pressure, and a flexible hose is used to remove heated water from the rod.

Thanks to these features, the bar can break near and far rings, and also work in a zone of high temperatures.

FIG. Figure 1 shows the detail of the device replacing the counterweight; in fig. 2 shows a boom; in fig. 3 - bar in the working and non-working position.

The boom consists of several telescopically joining one into another links /, of which the outermost link has an end 2, bent at a right angle. Inside the rod there is a perforated pipe 3 for supplying cold water under pressure to cool the rod. Heated water is removed through a flexible hose.

During operation, the rod rests on the roller 4 fixed at the furnace head. The end of the rod is in a two-roller. a holder 5 having special stoppers 6 for dead fastening 6. The holder 5 is located on a jack (of an automobile type) 7, with which the rod ends are moved vertically. The jack is mounted on the trolley 8, beams-rails 9, which are firmly attached to the floor. Instead of a counterweight to the frame of the trolley 8, a fixture 10 is attached, consisting of rigidly fixed strips 11 with rollers 12 and tension bolts 13. The movement of the trolley and rod is carried out by motor double drum winch with ropes attached to cart 8 and passing through blocks 14.V

To clean the oven, it is recommended to install supporting rollers 15 located against the wall and at the additional site / 6, the device of which should be provided in the cement compartment.
