Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a raw material distribution device that distributes raw material into a furnace by tilting an armor plate.

Conventionally, when raw material at the top of the furnace is dropped from the periphery of the large bell, an armor plate is used to change the distribution of the raw material falling from around the large level into the furnace, and this armor plate is moved. .

However, the conventional structure of moving the armor plate is
A drive shaft is attached to the back of the armor plate suspended from the top by a hook, and the other end of the drive shaft is led out of the furnace through the furnace wall, and is rotated using one end as a fulcrum in the drive section outside the furnace. The other end of the drive shaft is connected to the tip of the link to be obtained, and the armor plate is moved in the direction of the reactor core via the drive shaft, which is reciprocated in the axial direction by rotation of the link.

Therefore, by moving the armor plate in the direction of the reactor core, the falling position of the raw material can be changed in the radial direction within the reactor.
Since the drive shaft transmits power through the rotational movement of the links, the drive shaft also displaces in a direction perpendicular to the axial direction, so a hole the size of this displacement is made in the furnace wall. This has the disadvantage that dust inside the furnace may enter the drive part outside the furnace through this hole, and replacing the armor plate requires opening a hole in the furnace body above the armor plate. Because it is inserted and taken out from the hole,
It was troublesome to operate.

The present invention aims to provide a raw material dispensing device that allows the armor plate to be tilted at any angle and that allows the armor plate to be easily and safely replaced. Insert and support the distal end of the rod attached to the armor plate into the sealing box that can be attached, and fix the small lever to the shaft that is rotatably supported within the sealing box.
A wire rope tied to the end of the armor plate is guided into the ceiling box along the rod and tied to the small lever, and the large lever fixed to the shaft outside the ceiling box is connected to the drive source, and the large lever is fixed to the shaft outside the ceiling box. This device is characterized in that the armor plate is tilted through a wire rope and a small lever that rotates together with the lever.

Embodiments of the present invention will be described below with reference to the drawings.

A condo support/dustproof plate 2 having a hole 3 large enough to pass a rod and wire rope (described later) in the center thereof as shown in FIG. 2, a sealing box lid 4 having a flange portion 5, and a An armor plate 8 which constitutes the ceiling box 1 together with the side plate 6 and which is used to change the falling position of the raw material dropped through the outer periphery of the large bell I.
A rod 9 whose tip is pivotally attached to the center of the back surface of the rod 9 is supported through a hole 3 provided in the sealing box 10 rot support and dustproof plate 2, and its end is supported at the center of the inner surface of the sealing box lid 4. One end of wire ropes 10° 11 is tied to the upper and lower ends of the rod 9, and the other ends of each wire rope 10° 11 are guided into the sealing box 1, and the upper and lower ends of the inside and outside of the sealing box 1 of the rod 9 are tied together. Fixed roller 1 fixed to the side by appropriate means
2 to hold down each of the upper and lower wire ropes io and 1i.

In the ceiling box 1, two rotating shafts 13 and 14 are disposed horizontally and parallelly at upper and lower positions so as to be symmetrical with the rod 9 in between, and are supported by side plates 6.
In the center of each of 3 and 14 is a short small lever 15 and 1.
The ends of the wire ropes 10 and 11 are tied to the ends of the small levers 15 and 16, respectively, with the ends of the wire ropes 15 and 16 fixed, and rotated by the rotation of the rotating shafts 13 and 14 in the same direction.
The wire ropes 10 and 11 are alternately pulled and loosened via the small levers 15 and 16 (which swing), thereby tilting the armor plate 8 to an arbitrary angle.

One end of each of the inner rotating shafts 13 and 140 is airtightly protruded to the outside of the sealing box 1, and each of the small levers 1 is attached to each end.
5.16 is a large lever 1 extended in the direction of almost 180 degrees.
7. Fix each end of 18, and the rain levers 17, 18
A drive link 19 whose both ends can be bent with a hinge 20 connects the ends of each of the drive links with a hinge 21 so as to be rotatable, and a piston rod of a drive cylinder 22 is attached to the drive link 19 as appropriate. The large levers 1γ and 18 are simultaneously rotated in the vertical direction by moving the drive link 19 vertically by the operation of the drive cylinder 22, and the small levers 15 and 16 are simultaneously rotated via the rotating shaft 13.14. This constitutes a drive unit for tilting the armor plate 8.

In addition, 23 is a wire rope disposed between the tip of the rod 9 and the armor plate 8, and is for double safety to hold the armor plate 8 in case the wire rope 10.11 is cut.

24 is a furnace body, 25 is a fitting around an opening provided in the upper part of the furnace body 24, and 26 is a stopper.

Since the raw material distribution device of the present invention has a structure in which the sealing box 1 and the armor plate 8 are integrated with the rod 9 as described above, the armor plate 8 is connected to the furnace body 24 from the opening of the furnace body. The plate 8 is inserted into the furnace, the sealing box 1 is positioned outside the opening and brought into contact with the stopper 26, and the flange portion 5 of the sealing box lid 4 can be attached and detached to the mounting hardware 25 on the furnace body side with bolts, etc. The drive cylinder 22 is installed and used as appropriate.

If the raw material dropped through the large bell 7 is to be distributed to the center of the furnace, the drive cylinder 22 is operated and the large levers 17 and 18 are both rotated downward via the drive link 19.

Large lever 17°18, rotating shafts 13, 14, and small lever 15
, 16 are each integrated, so the large lever 17
By the downward rotation of the levers 15 and 18, the small levers 15 and 16 are rotated upward about the rotation shafts 13 and 14, respectively.

As a result, the wire rope 10 between the small lever 15 and the upper end of the armor plate 8 is drawn into the sealing box 1, and the wire rope 11 between the male lever 16 and the lower end of the armor plate 8 is loosened. The armor plate 8 rotates clockwise in the figure around the attachment point to the rod 9, and is tilted so that the lower part is pushed out toward the center of the furnace.

As a result, the falling raw material is changed in its falling direction by the inclined armor plate 8 and distributed toward the center of the furnace.

On the other hand, when distributing the raw material to the furnace wall side, the drive cylinder 22 is operated in the opposite direction to the above, and the large lever 17 and 1
8 are both turned upward, the small levers 15 and 16 are both turned downward, contrary to the above, and the armor plate 8 is moved in the opposite direction in the figure via the wire ropes 'io and ii. It is rotated clockwise and tilted so that the upper part is pushed out towards the center of the furnace.

This causes the raw material to be distributed to the furnace wall side.

In each of the above operations, the inclination angle of the armor plate 8 can be adjusted to an arbitrary angle by controlling the operating amount of the drive cylinder 22 and arbitrarily adjusting the rotation angle of the large levers 17 and 18. , the raw material distribution state within the furnace can be adjusted arbitrarily.

During operation, the rod 9 is supported by a rod support/dust-proof plate 2, which can support the load of the armor plate 8, and the dust in the furnace is prevented from entering the sealing box 1 by the plate 2. .

In addition, in the event that the wire ropes 10 and 11 break during operation, the armor plate 8 can be held by the wire rope 23.

The armor plate is used for repairs when the wire ropes 10 and 11 are cut, or for replacing the armor plate 8.
When taking the plate 8 out of the furnace, remove the bolts etc. fixing the mounting hardware 25 of the furnace body 24 and the 7 flange portion 5 of the sealing box 1, and then remove the plate 8 from the sealing box 1.
from the mounting bracket 25, and remove the rod 9 and the armor.
Pull out the plate 8 laterally from the opening in the mounting hardware 25.

At this time, in the present invention, since the rod 9 and the armor plate 8 are integrally attached to the ceiling box 1 and constituted as one cassette, by removing the ceiling box 1, the armor plate 8 can be moved in one motion. It can be easily taken out of the furnace through the opening of the mounting hardware 25.

When the armor plate 8 is replaced or repaired with a new one, the armor plate 8
can be set to the operating position all at once.

In the above embodiment, the wire ropes 10 and 11 are held down by the fixed rollers 12, but it is also possible to fix the wire ropes by providing a device for guiding the wire ropes through holes provided in the rod support and dustproof plate 2. Roller 12 may also be eliminated.

As described above, according to the raw material distribution device of the present invention, the armor plate can be tilted at any angle, and the raw material can be distributed arbitrarily in the furnace. It is possible to prevent furnace dust from entering the sealing box without moving the cassette, and the armor plate can be replaced all at once as a cassette.
