Description

one

This invention relates to devices for the repair of glass furnaces.

There are known devices for hot repair of the roof of the neche, containing an arched frame with flooring and drawbars. However, the hot repair of a large-size destruction center with a known device does not provide service at high temperatures.

The aim of the invention is to provide a service at high temperatures.

The goal is achieved by the fact that the arcuate frame is made water-cooled and is connected to a hard hinge plate.

Pa figs. 1 shows the proposed device; in fig. 2 - the same, top view with partial section; in fig. 3 is a section along A-A in FIG. 2

The arcuate frame 1 with a curvature equal to the curvature of the repaired section of the arch, made of pipes by welding, is a supporting structure. In order to ensure good circulation of coolant by directing its movement in the frame, the partition 2 is installed.

In the middle of the frame, the centerline lines of the fixture, are attached to it the trunnions 3, on which between the cheeks 4 there are hinged pads 5 for the pullnings 6, provided for hanging the fixture and perceiving both its own weight and the weight of repair bricks of the vault.

7 flooring with holes is welded to the frame

and at the ends to don the hooks when removing the devices from the fiery space of the furnace after the repair of the roof is completed. Pipes 8 and 9 are welded to the frame, respectively, for the supply and removal of cooling

liquids connected by elastic pipes 10 to the main.

Pad repaired section of the arch install blocks to guide the cables from the winch to t heaps, which are hung to them

using hooks. The suspended device is connected to the coolant line and is raised to a height that allows the device to be rotated into a vertical position. Device

immersed in a vertical position in the fiery space of the furnace until it is possible to turn the device around the trunnions to a horizontal position. Then the device is fixed to the arch, fixed in the right place of the repaired part of the arch and repaired the arch.

After the repair, pipes 8 and 9 above the outer surface of the roof are cut off or unscrewed with a threaded connection and then begin to lower the fixture.

At the same time, through the window on the wall of the fiery space, the hook-shaped end of the rod is inserted into the opening of the flooring in order to move the device to the window and take it out, then the cables are separated from the pull rod and removed. The holes in the vault are walled with mortars and mortar.

For more convenient hot repair, it is desirable to lower the temperature in the furnace to 1050-1100 ° C. Such a lowering of the temperature is not dangerous for the glass in the basins.

Subject invention

A device for hot repair of the roof of a nech, for example, a glass-melting furnace, contains its arcuate frame with flooring, which, in order to ensure service at high temperatures, the arcuate frame is water-cooled and connected to a hard-hinged bar.
