Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a discharging device for a granular material processing device 6 in a button, an ore firing facility, etc.

As a firing equipment for iron and steel stone,
: There is a Dwight Lloyd type kiln installation using moving pallets. This Dwight Lloyd type firing equipment is designed to invert with the pallet side walls fixed to the main body of each pallet 1 to 15 in order to discharge the fired ore. 〜Side walls (, 1) are separated, and a gap is required between adjacent pallet side walls to prevent collision of pallet side walls with each other due to thermal expansion during firing.

Further, as a conventional iron ore sintering equipment, there is a rotary type as shown in, for example, Chibu [1i', Publication No. 57-20552. In other words, a plurality of lattice-shaped pallets that can be rotated along an annular path are provided in the same plane, and iron ore to be fired is continuously supplied from a supply position on the annular path. , E is ignited in the stomach, and firing is completed while the pallet makes one revolution along the circular path, and is discharged from a predetermined ill exit position. However, in the method shown in Japanese Patent Publication No. 57-20552, although it is possible to eliminate the gap between the pallet side walls, it is possible to
When it comes out, it is separated and the iJl ore is finished. Since the iTG under the side wall and the upper surface of the pallet body are in contact with the upper surface of the pallet body, the barret 1 to water body is the pallet 1 to side wall 17 side. Sandwich the ore between the joints in contact with the baren 1-
When the side wall is deformed due to heat, a gap is formed between the pallet A~body and the barrette 1~side wall (this 41 leakage 1)
It causes lice. In addition, in these conventional systems, a downwardly curved rail is provided at the discharge position, and the pallet 1, which can swing downward, rests on this curved rail and runs on the supporting shaft. When the sintered ore on the pallet is tilted downward and the sintered ore falls out, the ejection distance becomes too large and the ejection distance is increased from the beginning and end of the ejecting device. In addition, when the pallet 1 returns to the horizontal position, the rollers of the pallet are guided to the bending wheel by J3, for example, when the pallet 1 is returned to the horizontal position. Otherwise, there is a risk that the vehicle will get caught and the vehicle will not be able to travel properly.

1 - The present invention with levers (1) aims to solve the above conventional problems and prevent unnecessary air leakage from occurring inside the granular body, thereby preventing the vehicle from being unable to run. be.

In order to achieve this object, the present invention provides a plurality of lattice-shaped pallets 1~ which are arranged on an annular path in the same plane and are capable of placing granules, and are capable of supporting the pallets 1~. A pallet frame is provided that is movable along the annular path and that can swing integrally with the pallet around the bins in the horizontal direction. The pallet underframe can be supported at the ejection position of , and can also be swung downwards around a horizontal operating axis, and this swinging causes the pallet underframe to be swung downwards. A tilting arm is installed to drop the granular material.

Therefore, since the discharge distance is shortened and there is no curved rail or rollers that can run on this curved rail like in the past, accidents such as the pallet 1 being unable to run due to getting caught in particulate matter, and the possibility of accidents are reduced. can be prevented.

It's a conveyor.

The effect of the above 4j formation will be explained. The rotating system 1 is rotated and the barre 1-5 is moved by Lj-'7m. At the supply position 62, the bedding ore from the bedding tank 59 is laid on pallets 1 and 5, and the raw material from the raw material tank 60 is Lay out 1 (υ, ore) and ignite it with the igniter r'IC+1. After that, baking is performed while the pallet 5 moves in the baking area 57. At this time, the air from pallets 1 to 5F is used for baking, and the exhaust air passes through grays i to 39, then to Nagi'; 1-44, go to the firing area via branch pipe 49
After removing the dust, the air is sent to Dow I-55 for exhaust air (Dow 51).

When the pallet 5 is moved from the firing area 57 to the cold area grass 18, the air above the barrette 5 is used for cooling, and the +J+ air passes through the grate 39 before being transferred to the baking area 5.
In the same way as in case 7, it is guided by the fixed collection tact 44,
Shun Dow 1-56 is sent to the cooling area through the branch pipe 50 to the ladder duct 52, and the dust is removed by the double damper 53.
is sent to the exhaust fan. The exhaust gas from the firing area 57 and the JJI gas from the cooling vA58 are treated and discharged through separate systems because the content of harmful dust is very different.The dust from the double damper 53 is The dust particles 1 to 51' are once sent to the firing area, and the dust collected in the header duct 51 (along with
t++ from there to the dust conveyor 8G and transported to the finished product conveyor 85.

After cooling is completed, the pallet 5 reaches the J)I output 64,
When the roller 35 of the parts 1 and frame 4 reaches the rail 75'' of the ejection device 63, this is detected by a limit switch, etc., and hydraulic oil is supplied to the actuating cylinder 79 to move the barrel h1m moving arm 7G. Open and operate. As a result, the C-valet underframe 44J tilts around the living room 34, causing the baked goods on the pallet 5 to fall. Baked! In order to reduce the weight acting on the pallet frame 4 when the objects fall, the pallet tilting arm 76 is moved as shown in Fig. 12 II: 3;! Position; 1, -C・If the opening movement is detected by a limit switch, etc., and the hydraulic oil in the operating cylinder 79 is drained, a small amount of balance 76 is opened, whereby the pallet 5 also returns to its original position and is moved to the child rear feeding position 62.

J3, the above series of operations is performed when the valves 1 to 5 are discharged by the ejector G.

The J yarn 171 passes through the ore sheet 84 and reaches the finished product conveyor 85''.
One well is discharged along with the dust from conveyor 8G.

/, t A';, When only the sea urchin baking device is configured, not shown in FIG. 11, the baked product discharged from the discharge device 63 is then sent to the neck for appropriate cooling and subjected to cold IJI. .

In addition, there is a bedding I on the platform that only consists of the cooling device! v59
, the raw material tank 60 and the ignition device 61 are not required, and the fired product from an appropriate firing device may be directly supplied to the supply position 62 (3).

According to this embodiment, since each member of the rotating system tM can be integrally rotated, the mutual positions of these members change d1f during the rotational movement, and the main seals such as the air seal between the pallet 5 and the wind box 3 Since the 4iA structure of the part can be covered with the seal structure between the fixed bodies, this seal part is not subject to fluctuation or deformation due to the traveling system. In addition, the sliding sealing device 4 () between the rotating collecting dow C]・8 as a mobile system and the fixed collecting dow 1 to 44 as a fixed type is configured separately from the Jukashi ij system. Therefore, it is prevented from being deformed due to the influence of load and heat from the running system.

As a result, iJ! This means that l can be significantly reduced.

Roughly speaking, the sealing mechanism between the wind box main body 23 and the pallet underframe 4 is as shown in FIG.
Since only the 5-minute opening operation is performed, there is no sliding contact part in the sealing mechanism here as well.

This is done by pressing the button I-1.
), during long-term use, there is a risk of wear on the end faces of the springs, which may cause wind to be generated, and the wear may also have a negative impact on the running system. However, there is a problem in that the air leakage increases, creating a vicious cycle, but according to this embodiment, wear and thermal deformation in the traveling system lead to air leakage. Furthermore, in this embodiment, the space constituted by the wind box 3 and the barre frame 4 is the gray one of the barrens 1 to 5.
It also has a collecting and discharging machine for the fired products that fall from the holes in 39.
The explanation has been given using an example where iron ore is calcined, but the granular material is not limited to this, and may be other materials, such as coal ash being calcined to form barene18. Good too.

As described above, according to the present invention, unnecessary air leakage is prevented, and the curved rail and the rollers that run on this curved rail as in the past are not damaged. It is possible to prevent the occurrence of accidents that would result in disability.
