Description

Power Supply Automatic Supply Device for Blower Outlet Opening {{POWER AUTOSUPPLT APPARATUS OF BLAST FURNACE OPENER}

The present invention relates to an automatic supply device for a drive source related to the opening of the blast furnace opening opening, more specifically, the driving source required for the opening of the blow opening is connected to the articulated swivel joint, so The present invention relates to a blast furnace outlet opening automatic supply device for preventing the connection portion from being broken or leaking of the driving air and water.

In general, blast furnaces use molten iron to reduce molten ore using hot air to produce molten iron. These molten irons collect at the bottom of the blast furnace. At this time, the use of the open air, and the situation that the device that can supply the driving source for operating the open air is urgently required.

Conventionally, as shown in FIG. 1, the blower air forms a central axis next to the outlet port 1a of the blast furnace 1 and rotates by the pneumatic motor 2 to fix the frame on the outlet port 1a. Fixing bar (3) is formed to connect the hook 5 installed in the front end frame (4) of the opening machine and then open the tap opening (1a).

Meanwhile, the primary bit 6 mounted on the primary air is rotated by the operation of the pneumatic motor 2, which is supplied through the water supply pipe 7 and the air supply pipe 8 by an operation lever (not shown). It is installed so that forward rotation and reverse rotation are possible by the air.

The outlet opening 1a is sealed with a mud gun made of a mud material of indeterminate refractory (an apparatus for filling the body with a mud material of indeterminate refractory to seal the outlet opening) (not shown).

Therefore, in order to discharge the molten iron (1b) in the blast furnace (1) to the external large waterway (9), it must pass through the outlet opening (1a) at this time to operate the blower to penetrate the mud gun.

The driving source in which the primary air is operated is an operating source necessary for the hammering of the hammer when advancing the primary air and the reversal of the hammer required for the reverse of the primary air is the air for operating the pneumatic motor and a drill bit mounted in the primary air. The operating source in the forward direction and the reverse direction is also air, and high pressure water (7 kg) is applied to the middle of the blow bit 6 when opening the outlet 1a with a blower to penetrate the outlet 1a. / Cm 2) and air (9kg / cm 2).

The operating source of the drive element is mainly using air or water, and each connecting swivel joint, piping, etc. is damaged due to the misoperation of the operator or the high temperature, so that the gas of the proper pressure cannot be supplied. There is a problem that the penetrating operation of 1a) is interrupted.

The present invention has been invented to solve the above problems, it is possible to smooth the penetrating operation of the exit port by providing the operator automatic supply device mounted to the blower to prevent the leakage and damage of the operator. It is an object of the present invention to provide a drive source automatic supply device for blower openings.

The present invention for achieving the above object is a multi-stage drum with a lower and lower equilateral triangular support installed on both sides of the base of the supply device, a multi-stage drum coupled to the outer peripheral surface of the shaft rotatably installed between the support and the outer diameter of the multi-stage drum It is formed in different sizes according to the size of the driving force of the blower air, and the forward-driven air piping drum for hammer forward, the reverse-driven air piping drum for hammer retracting, the drill forward-rotating air piping drum, and the drill reverse rotation The air pipe drum and the water pipe drum for drill spraying are sequentially formed, and the tape box part installed on one side of the support for winding the flexible heat hose wound around the multi-stage drum smoothly, and the spring box part. This includes the sprockets that are chained together to transfer the restoring force to the shaft.

Hereinafter, described in detail with reference to the accompanying drawings showing the present invention.

2a and 2b is a front view and a side view showing a drive source automatic supply device according to the present invention, the present invention is provided with a support triangle 11 of the equilateral triangular lower side on both sides of the base 10 and the support 11 ), The shaft 12 provided with the multi-stage drum 20 is rotatably installed.

One side of the shaft 12 is provided with a nipple 13 for injecting grease to enable lubrication of the rotating part, and the outer diameter of the multi-stage drum 20 has a different size about the shaft 12. This is determined by the magnitude of the driving force of the blower.

That is, the multi-stage drum 20 has a forward motion of the hammer forward air pipe 21, a reverse motion air pipe drum 22 for the hammer retreat, a drill forward rotation air pipe drum 23, and drill reverse rotation The air piping drum 24 and the water pipe drum 25 for drill injection are provided, respectively.

Meanwhile, in order to allow the flexible heat-resistant hose 40 wound on the multi-stage drum 20 to be smoothly wound, a tape box 30 is installed on one side of the support 11 to use elastic restoring force. The chain 32 is installed in the sprocket 31 for transmitting the restoring force of the mainspring box 30 to the shaft 12.

The present invention configured as described above operates a single opening air to open the opening port 1a of the blast furnace 1, so that the plurality of heat-resistant wound around the multi-stage drum 20 when the first bit 6 is moved to the opening port 1a side. Hose 40 is released.

The length of the heat-resistant hose 40 released from the multi-stage drum 20 varies depending on the diameter of each drum, which is the heat-resistant hose 40 required for the blow bit 6 to open the tap hole 1a. By the length of the is possible by the difference in the diameter of the pre-machined drum.

On the other hand, when the opening bit 6 is completed in the initial state after the opening of the outlet opening 1a, the restoring force of the elastic member embedded in the tape box 30 is transmitted through the sprocket 31 and the chain 32. As the multi-stage drum 20 is rotated, the released heat-resistant hose 40 is wound around the multi-stage drum 20, thereby preventing the heat-resistant hose 40 from being damaged.

It is a very useful invention that can improve the yield by stable operation since it is possible to perform the one-step through the outlet opening smoothly by preventing the leakage and damage of the connection of the pipe installed in the working air blower.
