Description
Technical Field
The utility model relates to a blast furnace ironmaking field, in particular to a blast furnace hearth cleaning and transporting device.
Background
When the metallurgical furnace is in overhaul or in middle overhaul, furnace burden in the furnace needs to be cleaned up, and preparation is made for filling furnace charge for opening the furnace. Although the height of a stock column in the furnace can be reduced by stopping the furnace through an empty stock line in the prior art, part of furnace burden can not be reduced, melted and discharged, the stock line can only be lowered to a tuyere, a large amount of furnace burden in a furnace cylinder needs to be cleaned up when overhauling is carried out, and particularly, the central dead stock column of the blast furnace is hard and difficult to clean. The traditional method for cleaning the furnace burden is the simplest method that a simple tool such as a rake is used for cleaning the furnace burden from a blast furnace tuyere, after the tuyere is cleaned up, the tuyere is too far away from the furnace, when the tuyere cannot be cleaned up, a large amount of manpower is required to be concentrated, the tuyere enters the furnace, a plurality of simple chutes are installed, and a furnace hearth is cleaned up through the manpower.
Disclosure of Invention
In order to solve the big difficult problem of the blast furnace burden clearance degree of difficulty, improve the speed of quick clearance, the utility model aims to provide a blast furnace hearth clearance conveyer, this device simple manufacture, convenient operation can transport the furnace charge in the hearth outside the stove through mechanized clearance, transport, reaches the purpose of quick clearance furnace charge.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a blast furnace crucible clearance conveyer, includes the outer platform of stove that sets up on the wind gap platform that sets up in the side of the blast furnace body and wind gap platform, set up the hoisting accessory that rises on the outer platform top surface of stove, set up rubber belt conveyor on the wind gap platform, rubber belt conveyor's outside position is on the wind gap platform, rubber belt conveyor's inside portion extends in the blast furnace and is setting up an interior workstation, set up a small-size excavator on the workstation of stove, the small-size excavator organism goes upward through wire rope and passes blast furnace roof opening with the hoisting accessory that rises link to each other, rubber belt conveyor is the zigzag and arranges, rubber belt conveyor's inside position is less than the position of the outside lateral part of rubber belt conveyor.
The utility model discloses use stove outer covering and wind gap platform as supporting, set up stove outer platform to the blast furnace steel casing in wind gap platform department, demolish three sets in the suitable wind gap of a position (big cover, well cover, little cover), from this wind gap installation sealing-tape machine, the lower part of sealing-tape machine sets up firm sticky tape strutting arrangement, ensures that the sealing-tape machine can be stable when the operation.
The utility model discloses the flat zigzag of sealing-tape machine appearance is arranged, the part of going into the stove is through circular-arc frame preparation, the support adopts demountable assembly adjusting device, ensure that the sealing-tape machine can carry out certain displacement from top to bottom in the stove, sealing-tape machine in the stove adopts the detachable device, outside furnace charge fortune output stove, when the elevation descends, the sticky tape strutting arrangement in the adjustment stove, use the jack-up to put the stove inside branch of hanging sealing-tape machine, the position of dismantling of adjustment sealing-tape machine, make sealing-tape machine displacement from top to bottom, ensure that the furnace charge elevation descends, when digging the machine does not have loading furnace charge height, with the height of adjustment sealing-tape machine, reach the height that digging the machine can load.
The utility model discloses a device is gone into for mini-excavator and hanging into to another key component, and mini-excavator is through installing in the lifting device of the jack-up of furnace roof and the controlling means of lifting device, hangs into the stove by the furnace roof, accomplishes the excavation and the clearance operation of furnace charge. The hoisting device and the hoisting device have two functions, one function is used for hoisting the small excavator, and the other function is used for vertically displacing the belt conveyor into the furnace, so that the belt conveyor is hoisted when the belt conveyor vertically displaces.
The small excavator is hoisted into the furnace through the hoisting device, the adhesive tape machine is installed, furnace burden in the furnace cylinder is excavated through the small excavator, the furnace burden is placed on the adhesive tape machine, the adhesive tape machine is operated and conveyed, the furnace burden is conveyed out of the furnace through the air opening, the furnace burden is poured into the conveyer outside the furnace, and the conveyer outside the furnace is adopted for pulling and conveying, so that the aim of mechanically cleaning the furnace burden is fulfilled. The device is used when the hearth of the blast furnace is cleaned, saves manpower and material resources, greatly improves the maintenance efficiency, brings convenience for maintenance, and saves time for the blow-in of the blast furnace.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
