Description

The invention relates to devices for burning materials in rotary kilns and can be used to move burners and raw nozzles in a rotary kiln.

The aim of the invention is to simplify the adjustment of the position of the burner.

FIG. 1 shows a device for moving the burner; a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

The device comprises a carriage 1 of horizontal movement of the burner 2 along the axis of the furnace along rails 3, a front 4 and rear 5 supporting elements, a mechanism 6 of horizontal movement and a mechanism 7 of vertical movement of the burner 2.

The horizontal movement mechanism 6 comprises a guide 8, circular in cross section, rigidly connected to the uprights 9 of the supporting elements of the trolley 1 and passing coaxially through the carriage 10, the KOTO-J i includes a housing 11 with the slide supports 12 and a gear shaft 13, meshed with a circular gear rack 14, a guide 8 and a worm gear 15 connected to an electric motor. 16 a V-belt drive 17.

The vertical displacement mechanism 7 of the front support member 4 is made in the form of a screw telescopic jack and comprises a guide 18 rigidly connected by a bracket 19 and legs 20 with a horizontal displacement carriage 10, and a round slider nut 21 telescopically fixed in the guide 18 and moved by screw 22. The screw 22 of the jack is fixed in the longitudinal direction in the thrust bearings 23 of the guide 18 and is connected to the worm gearbox 24, which is connected to the electric motor 25 by the clutch. The gearbox 24 and the electrode The drive 25 is fixed on the strut 26 of the right gear 18. The mechanism 5 of the front support member 4 is connected by a ball bearing to the burner. Ball bearing contains the ball. 27, fixed in the nut 21 of the jack on the plug 28, and the ball clip 29, rigidly connected to the burner 2.

The mechanism 7 of the vertical movement of the rear support element 5 is connected to the burner 2 split flange 2347132

the coupling made by the flange 30 at the end of the jack nut 21, and the nozzle 31 rigidly connected to the burner 2.

5 The device for moving the burner operates in the following modes.

The burner 2 moves parallel to its axis in order to approach (remove) the burner (torch) to the material being burned in the rotary kiln while both carriages 10 move horizontally or both vertical carriages of the telescopic jack 21 moving in one direction.

The burner 2 is moved to change the angle of inclination of the axis of the burner (torch) to the axis of the rotary kiln when

20 moving in either direction of one of the horizontal movement carriages 10 or one of the vertical movement carriages - the jack nuts 21. .

25

The burner 2 moves parallel to its axis in order to change the burner’s (torch) depth into the rotary kiln when moving in any

, - the direction of the carriage 1 longitudinal movement.

In addition, the longitudinal movement carriage 1 is designed to completely remove the burner 2 from the rotary kiln when the rotary kiln stops or repairs.

The proposed burner replacement device requires minimal disassembly, namely, disassembling the connection of the vertical movement mechanisms to the burner, which allows reducing the simple rotary kiln to replace the burner to 10-15 minutes. . In addition, the use in the proposed device of closed power transmissions increases the reliability of the device (furnace), and the application in the device is electrically; or hydraulic drives allows remotely changing the position of the burner in the kiln, which improves the operating capabilities of the rotary kiln, in particular when automating the roasting process.

The advantage of the proposed device in comparison with the known

55 is the ability of horizontal and vertical displacement mechanisms to absorb the load from the burner in both directions, which is 35

produces a variety of applications for these mechanisms: it is possible to place mechanisms for horizontal and vertical movement on one and both ends of the trolley of longitudinal movement when placing the burner as above the trolley

downstream and under the trolley. In various applications of the proposed mechanisms of horizontal and vertical movement, only the design of the connection of the burner to the mechanism of vertical movement is different.
