Abstract

The invention relates to blast furnace production and can be applied in blast furnace charging devices with tray batch load distributors. The purpose of the invention is to save coke and increase the service life of the device by reducing fluctuations in the distribution tray. The distributor is provided with chevron gears 11 rotatably mounted on the rods 9 of the drives 8 and changing the tilt angle of the tray, forming kinematic pairs with a chevron gear wheel 12. When the rods 9 are vertically moved, the force through the chevron gear 11 is transmitted to the wheel 12 and through the rod 14 to Tray 7, change its angle of inclination. A constant contact of the drive of the angle of inclination with the wheel 12 is provided, which reduces the possibility of oscillations of the tray 7. 2 sludge.

This invention relates to ferrous metalworking, in particular, to the mechanical equipment of blast furnaces,

The purpose of the invention is to save coke and increase the service life of the device by reducing fluctuations in the distribution tray.

Fig, 1 shows the device, a general view; Fig, 2 - node chevron gears

The distributor of the charge of the charging apparatus of the blast furnace contains a tray rotation mechanism that includes an electric motor, a propeller shaft, an angular gearbox, a driving shaft (not shown), which interacts with the ring gear 1, which is rigidly fixed by means of a bolt mount 2 with a hollow cylinder 3 and is described through the bearing 4 to the stationary parts of the loading device, a bracket 5 is rigidly connected with the hollow cylinder 3, in which the support 6 is mounted, against which the e-ts swing the distribution chute 7,

The tray swing mechanism includes hydraulic cylinders 8 (at least three located at an angle of 120 °), the rods 9 of which interact with movable housings 10 in which at least three chevron gears 11 are mounted on the bearing the other, also at an angle of 120, the Chevron gear 11 is in engagement with the chevron wheel 12, which through the hub 13 contacts the hollow cylinder 3 ° C; OPPORTUNITIES of axial stir: yen (for example, a spline joint),

 The connecting rod 14 simultaneously interacts with the hub 13 and the small shoulder of the swing mechanism of the tray 7,

The charge materials are delivered to the distribution tray 7 through a stationary charge chute 15, Chevron gear 11 is mounted on an axis 16 with an end cap and 17 on angular contact bearings 18, fixed n. lids 19,

The device works in a speedy manner.

The torque from the electric motor is transmitted to ring gear 1, which is rigidly connected to the hollow cylinder 3, which is not covered by a microchip 5 with a distribution tray 7. Thus

Thus, the distribution chute makes circular movements relative to the vertical axis of the distributor, while simultaneously with it, due to the interaction between the hollow cylinder 3 and the hub 13, a shevron wheel 12 and a chevrong on a gear 11 receive rotational movement,

Tray roll is performed as follows. The force of the hydraulic cylinder 8 is transmitted through |) without radial and thrust bearings 18 to the chevron gear. Because of the fact that the chevron transmission is non-aerated and self-adjusting, the force and related. with it, the movement of the housing 10 and the gear 11 are transmitted to the chevron wheel 12 and further through the hub 13, the connecting rod 14 to the small arm is distributed. trough tray 7, which leads to a high-quality movement of the latter,

Swinging movements of tray 7, ta-. The IMC can be performed regardless of whether the tray 7 rotates or is at rest, taking into account that the tray 7 is limited in mixing (tight coupling through self-adjusting non-driving chevron gear with hydraulic cylinder 8, in turn, leads to oscillations of the distribution tray 7 and improvement of the distribution of the charge materials in the blast furnace,

The invention provides an improvement in the distribution of the charge materials in the blast furnace by limiting the oscillations of the distribution section and reduces the repair time by 1.5 times.

Claims (1)

Invention Formula A blast distributor of a blast furnace charging device containing a stationary charge chute, enclosing its hollow cylinder with a toothed crown, which is kinematically connected with a rotating drive bracket, rigidly. attached to the lower part of the hollow cylinder, with a support to which the distribution tray is hinged, a gear wheel, covering the hollow cylinder mounted with the possibility of vertical movement relative to it, is connected by means of a connecting rod with a distribution tray and with the stems of the angle change drives pan tilt, characterized in that, with 5 .15078016 In order to save coke and increase water variation in the tilt angle of the tray of the device's service life by reducing the possibility of rotation and the toothed oscillation of the distribution tray, it is equipped with chevron gears mounted on the rods; the wheel flange is also chevron engaging with chevron gears . change the angle of inclination of the tray with the possibility of rotation, and the gear the crown of the wheel is also chevron engaging with chevron gears.
