Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an apparatus for removing slag, which removes slag from a container without tilting the container.

Examples of conventional slag removal include: (1) Slag removal in a melting furnace is carried out by tilting the furnace, moving the slag to the tap hole, and scraping it out manually or mechanically.

(2) Slag is removed from the ladle by tilting the ladle and scraping it out manually or mechanically.

(3) The manual work in (1) to (2) above involves scooping and scraping with a scraper, board, shovel, shovel, etc., and the mechanical work is a work method in which manual work is directly converted to mechanical power. In addition to the above-mentioned problems when removing slag by horizontally moving, rotating, etc. using hydraulic pressure, electric power, etc. to remove scraping rods, plates, etc., It has poor properties and is difficult to excrete.

(2) When the slag surface hardens to the point where it is necessary to break it, mechanized equipment has its limits and becomes unusable.

(3) When a machine is used, there are drawbacks such as the space it occupies in a two-dimensional manner.

The present invention solves such problems and exhibits its function in removing hardened slag or slag with poor fluidity.

In addition, the present invention provides a device that is installed in the space above the slag surface, making the device compact and capable of dealing with fluctuations in the location of the slag surface.

The present invention provides a structure in which a scraping board is fixedly arranged facing outward on the surface of a rotating member, and a cable is connected directly or indirectly to the rotating member.
The upper part of the copper strip is connected to a lifting device, and one or both of the ropes is raised and lowered by the lifting device, and the rotating member is rotated to place it on the slug scraping plate inside the container and discharge the slug. A slag discharge device characterized in that the slag discharge device is characterized in that the scraping plate is fixedly disposed on the surface of the rotating member facing outward, a cable is connected directly or indirectly to the rotating member, and the cable is connected to the rotating member directly or indirectly. The upper part is connected to an elevating device and is also connected to a rotating device such as the elevating device, so that the scraping board can be freely pivoted in a horizontal direction, and one or both of the ropes can be raised and lowered by the elevating device. This slag discharging device is characterized in that the rotary member is rotated and placed on a slag scraping plate inside the container to discharge the slag inside the container.

Hereinafter, one embodiment of the present invention will be explained in accordance with the figures.

A scraping plate 1 having a portion for scooping out slag is fixedly disposed outwardly on the surface of a rotating member 20.

The scraped rice 1 of this example has the role of crushing slag, and when scooping up a fluid slag, the scraping plate 1 is bent as shown in the drawing.

In addition, the rotating member 2 is one with its own weight in order to give the scraping plate 1 the power to crush and scoop up the slag, but in this example, a counterweight is used.

The shape of the rotating member 2 is not limited to a cylindrical shape, but may be angular or arcuate.

In order to rotate the scraping board 1 and the rotating member 2, cables such as chains 3 and 4 are connected to the rotating member 2. In this example,
Two sets of chains 3 fixed to four points on the rotating member 2,
It consists of 4.

The chains 3 and 4 are then moved to a lifting device such as an unwinding device 5.
6 and lower the scraping board 1 by operating the rolling out devices 5 and 6.
It is rotated to crush the slag, scoop it up, and discharge it outside the container.

In the present invention, the unwinding devices 5 and 6 are connected to a rotating device 8, and the chains 3 and 4, the rotating member 2, and the scraper plate 1 are rotated to process the slag in the container 7 into adult fish.

The turning device 8 of this example is composed of a turning device motor, a speed reducer, a turning device chain wheel, a turning device chain, and the like.

Further, in the present invention, the unwinding devices 5 and 6 are connected to the traversing device 11 via the traversing device frame 9, the traversing rail 10, the wheels 13, etc.
．． 12 and the transverse rail 10 is connected to the traveling device 14.
The scraping board 1 is made movable.

Further, the transverse rail 10 and the traveling device 14 are connected to a connecting member 15.
It is connected by .

The present invention will be explained in detail below.

First, when crushing the slag that is about to harden in the container 1, the unwinding devices 5 and 6 are activated to give the chain 3.4 an up and down motion, and the tip of the scraper plate 1 is used to crush the slag.

After crushing, the scraping plate 1 is inserted into the slag of the container 1, and the chain 3 is lowered by the unwinding device 5. At the same time, the unwinding device 6
The chain 4 is wound up, the rotating member 2 is rotated, and the scraping plate 1 is operated as shown by reference numerals 1' and 1'' in the first part to scoop out the slag.

The scooped slag is discharged onto the scraper plate 1 by lowering the chain 4 and raising the chain 3 in the opposite manner to the above operation.

In this case, if the slag is difficult to separate from the scraping plate 1, the claws (not shown) are provided opposite each other, and the spacing between the claws 9 is made freely movable by a cylinder or the like, and the scraping board is placed between the claws. 1, move the claws to shorten the distance between the claws, and remove the scraping board 1.
Raise the chain 3゜4 at the same speed and scrape it off with the tip of the slug claw.

In addition, in the present invention, the scraping plate 1 in the part that comes into contact with the slag
The rotating part 2 and the chains 3 and 4 are provided with a refractory lining to prevent melting damage caused by hot metal, molten steel, and slag, and to improve the peeling of slag.

In addition, in order to achieve good separation between the slag, hot metal, and molten metal, the scraper plate 1 is provided with holes of an appropriate size and number depending on the fluidity of the slag.

The amount of slag removed per time can be adjusted by changing the weight of the rotating member 2 and the distance between the supporting points.

The slag scooping function of the device of the present invention is to move the scraping plate 1 attached to the rotating member 2 (counterweight) to the chains 3 and 4.
It can be obtained by rotating the

That is, (1) the rotating member 2 and the scraping plate 1 are moved up and down, rotated, and moved horizontally by a device to follow the fluctuations of the slag surface in the container, and also to remove the slag in the container (which cannot be taken out). can.

(2) It is easy to isolate the drive system from convective heat, radiant heat, gas, dust, etc. received from slag of hot metal, molten steel, etc. Also, since the parts that come into contact with slag are simple, it is also possible to The device is safe and highly reliable because the scraping plate 1 is placed on the wall and the slag scooping part collides with the wall, which does not have the same adverse effect on the drive device.

(3) The device of the present invention can be implemented by using conventional general equipment (hoist chain block, crane) as the unwinding, turning, traveling, and traversing equipment, which is economically advantageous.

(4) Particularly effective in removing slag when the slag surface is hardened or fluidity deteriorates.

In other words, it can perform crushing and scooping functions.

(5) Conventionally, two to three people are required to manually remove the slag with a scraper, but the present invention has remarkable effects, such as being able to do it with just one driver.
