Detailed Description
The structure of the present invention will be further described with reference to the accompanying drawings and specific examples, but the present invention is not limited thereto.
The method is carried out by matching machines with manual work, firstly, the dumping direction of the gravity dust collector is determined, according to the field condition, in order to prevent the falling of the gravity dust collector from touching the blast furnace body in the dumping process, firstly, the descending pipe of the gravity dust collector is separated from the blast furnace body completely by manual work, then, two concrete upright columns at the dumping side are all broken by a lengthened arm crusher, the gravity dust collector at the dumping side loses support and is dumped to the ground along with the gravity dust collector, and finally, the furnace body is broken by machines. The concrete steps are as follows:
as shown in fig. 1 to 5, an embodiment of the present invention discloses a method for dismantling a gravity dust collector, including the following steps:
the method comprises the following steps: a constructor stands on a dust remover platform, a cutting gun is bound with a long gun to cut a pipeline connected with an external pipe network into small blocks and freely fall onto the platform, and finally, the pipeline is thoroughly cut off and separated from the outside;
firstly, the gravity dust collector is separated from the peripheral connected components, so that the subsequent operation is facilitated.
Step two: a group of constructors stand on the dust remover at the joint of the two descending pipes to horizontally cut off the descending pipes, and at the moment, the pipeline is still in a stable state due to bottom support;
step three: another group of constructors put on the blast furnace platform to cut the downcomer in blocks, wherein the position is positioned on a 40.7 m platform, the downcomer is freely dropped to the ground in blocks, and after the downcomer is completely cut off, the bottom of the downcomer is separated from the dust remover, so that the part of the downcomer falls to the ground under the action of self gravity to complete separation work;
through the second step and the third step, the gravity dust collector is separated from the blast furnace body, and the influence on the blast furnace body is not generated when the gravity dust collector is dismounted.
Step four: after the cutting treatment of the two descending pipes at the top is finished, constructors go up to a platform at the top of the dust remover, a steel wire rope with the diameter of 20mm is tied and hung on a chimney above the descending pipes, and the constructors withdraw to a safe range;
step five: the method comprises the following steps of firstly breaking a No. 1 upright column and then breaking a No. 2 upright column by using a crusher, wherein the bottom of a dust remover is provided with 4 upright columns, wherein the No. 1 upright column and the No. 2 upright column are adjacent 2 upright columns;
the stand of dust remover is as shown in the figure, is 1 stand, No. 2 stands, No. 4 stands and No. 3 stands respectively according to the order, and wherein No. 4 stands and No. 3 stands remain and do not abolish.
Step six: and (3) remotely drawing the pre-tied steel wire rope by using a 460 type shearing crusher to realize directional removal of the dust remover and dumping to the ground.
Specifically, the distance between the 460 type shearing crusher and the gravity dust collector is not less than 80m, and the steel wire is tensioned at a position which is 30 degrees north east in the traction direction.
In the fourth step, a constructor firstly beats the platform with a hammer before going to the platform at the top of the dust remover to confirm the integrity of the platform, and then carries out the next step of work after the steel springboard is paved severely by corrosion.
In step five, when the column No. 1 is broken, the position of the column No. 1 3 meters away from the ground is completely broken.
In the fifth step, when the column No. 2 is broken, the connecting line of the column No. 3 and the column No. 4 is positioned between the connecting line of the column No. 1 and the column No. 2 and the crusher.
Play the effect of protection breaker, prevent to topple over towards breaker and staff's direction because of empting of dust remover.
The crusher here is an extended arm crusher.
In the fifth step, when the No. 2 column is broken, the position of the No. 2 column, which is 3 meters away from the ground, is gradually dismantled, and when the diameter of the No. 2 column, which is 3 meters away from the ground, becomes one third to one fourth of the original diameter, the breaking is stopped.
The initial size of column No. 2 was 700mm X700 mm, and the column was stopped when the column had a diameter of 250mm after the column had been ruptured.
If the column No. 2 is broken at one time, the dust remover cannot be toppled in the preset direction, and meanwhile, the toppling speed is too high and is not easy to control. When the No. 2 column is broken and thin, the dust remover can be inclined towards the preset direction by pulling the dust remover through the steel wire rope. Is safe and reliable.
The dust remover is short for a gravity dust remover.
The above description is of the preferred embodiment of the invention. It is to be understood that the invention is not limited to the particular embodiments described above, in that devices and structures not described in detail are understood to be implemented in a manner common in the art; those skilled in the art can make many possible variations and modifications to the disclosed embodiments, or modify equivalent embodiments to equivalent variations, without departing from the spirit of the invention, using the methods and techniques disclosed above.
