Description
The present invention relates to a kind of distribution device, particularly a kind of hydraulicdriven loading device that has distributor chute.Its distributor chute not only can be done forward and reverse rotation but also can swing, and pendulum angle is adjustable, and adopts hydrostatic transmission all.
The present invention is applicable to the blast furnace with high pressure furnace roof, also can be used for shaft furnace.
At present the loading device of blast furnace mainly contains two big classes, the first kind has bell, and second class is no bell.With the present invention the most approaching be U.S. Pat-3899088, IPC:F27B
120.
U.S. Pat-3899088 is two kinds of similar distribution devices of description scheme simultaneously.This distribution device all by electric motor and straight hydrodynamic cylinder pressure transmission, with regard to the distribution device of above-mentioned two kinds of patterns, is summarized as follows now:
First kind of distribution device, its rotation transmission is positioned at pivot angle transmission top.This distribution device is mainly by can be around the interior pipe of blast furnace vertical center line rotation, and outer tube that concentric can be for vertical movement and mechanical drive thereof are formed with it.Insert in the fixed raw materials groove at interior pipe top, be provided with tightness system between outer wall of inner tube and the intake chute inwall, and be connected with gear ring by annular plate, gear ring is again by idle pulley and motor shaft end toothing, the gear ring root is tapered, by the supporting of two rows cone pulley, constitute supporting device with ring-type box-shaped bearing, supporting device is installed on the throat platform.Interior pipe lower end is symmetric two minor axises that are provided with on its radial barrel, the gib head of chute hangs on this axle.Its both sides below the chute gib head, hinged by pair of links and outer tube lower end.
Chute rotatablely moves and is rotated by the geartransmission idle pulley of electric motor, gear ring, interior pipe.Flange on the outer tube props up on rotating supporting device.This bracing or strutting arrangement props up again on many power cylinders.Power cylinder props up on throat platform.
In being contained in, sealing member reaches between outer tube and the rotating supporting device between pipe and the rotating supporting device.
Carrying out the refrigerative tightness system by refrigerating unit is placed between outer tube and the top cone.
Superposition section between interior pipe and the outer tube is formed slideway by guide rail and guide groove, so as to transmission and guiding.The most of length in outer tube bottom is positioned at high furnace interior, and inner and outer pipe all is communicated with blast furnace.
The swing of chute is by hydro-cylinder push-and-pull annular brace device, drives the outer tube lifting, makes it pendulum by connecting rod.When interior pipe rotates,, can drive outer tube and rotate synchronously by slideway between the inner and outer pipes.
The rotation of above-mentioned chute and swing can be carried out separately also can carrying out simultaneously.
Second kind of scheme: its chute pivot angle transmission mechanism is above rotary actuator.With the key distinction of first kind of distribution device be interior pipe lifting and passive rotation.Outer tube bottom hung chute also drives the chute rotation.Make the connecting rod two ends of chute pendulum hinged with chute head and outer wall of inner tube respectively.
