[0002]

2. Description of the Related Art Generally, slag aggregate used for road aggregate, concrete aggregate, etc. is melted at 1000 ° C. or more in a melting furnace after incineration of waste such as sewage sludge, and the obtained molten slag is used as a container. (Hereinafter referred to as a mold), and it is known that it is cooled and solidified for a predetermined time within a specific temperature range in a solidification processing chamber, and then manufactured.

For example, Japanese Patent Application Laid-Open No. 5-58690 discloses a technique for producing hard slag aggregate using lime-based sewage sludge as a raw material. This involves incinerating lime-based sewage sludge and melting a raw ash having a weight ratio of CaO to SiO ₂ of 0.8 or more and 1.3 or less, and then, in a temperature range sandwiching the crystal precipitation point, the CaO and SiO ₂ are mixed. The weight ratio is subdivided and cooling is performed by changing the cooling rate according to the division, and is manufactured by an apparatus as shown in FIG.

FIG. 9 is a side sectional view showing a conventional apparatus for solidifying a melt, that is, an apparatus for producing hard slag using lime-based sewage sludge as a raw material.

In this hard slag aggregate manufacturing apparatus, the solidification processing chamber 1 is surrounded by a top plate 2, a floor plate 3, and left and right side plates 4a and 4b. ,
A heat resistant material 5 is stretched around each inner surface.

[0006] A pair of left and right support members 6 extending in the same direction as the solidification chamber 1 are embedded in a heat insulating material 5 stretched on the upper surface (inner surface) of the floor plate 3. Guide rails 7 are laid, and a mold 8 serving as a container for receiving molten slag is provided on these guide rails 7.

The mold 8 comprises a container body 10 and a double-opening lid 11 for opening and closing the upper end opening of the container body 10.

The container body 10 has an inverted truncated pyramid shape in which the upper part opens in a divergent shape, and a heat insulating material 12 made of ceramic fiber or the like, and an inner mold 25 made of SUS310S or the like disposed on the inner and outer surfaces of the heat insulating material 12. And the outer mold 26. The two molds 25, 26 are connected by a connecting material.

Each lid 11 is basically formed of a heat insulating material 13, and a metal plate 27 is arranged on an outer surface of the heat insulating material 13.
It is pivotally attached to the container body 10 so as to be rotatable in the direction of the arrow.

Each of the carts 9 has a plurality of hanging metal fittings 23 for detachably supporting the mold 8 on the upper surface of each body.
Are fixed, and casters 14 are rotatably mounted at a plurality of positions on the lower surface of each main body, and these casters 14 are mounted on the guide rails 7 so as to roll.

A drive chamber 15 extending in the same direction as the solidification processing chamber 1 is provided below the solidification processing chamber 1. Drive room 1
5, horizontal shafts (only one is shown) 16 extending in the left-right direction are disposed at both longitudinal ends (front and rear) of the drive chamber 5. Both ends of the horizontal shaft 16 are driven through two sets of bearings 17, 18. Each is rotatably supported by the housing.
Further, a pair of left and right sprockets 19a, 19b is fixed to each of the horizontal shafts 16, and one of the horizontal shafts 16 is driven to rotate by a motor (not shown).

Chains 28a and 28b extend between the front and rear sprockets 19a and 19a (only one is shown) and the sprockets 19b and 19b (only one is shown), and a number of connections are made between the chains 28a and 28b. At the center of the outer surface of these connecting plates 22, pressing rods 20 protrude outward, and the protruding ends of these pressing rods 20 form the floor plate 3 and the heat insulating material 5 on the upper surface of the floor plate. The solidification processing chamber 1 is exposed to the inside of the solidification processing chamber 1 through a slit 21 formed substantially continuously throughout the longitudinal direction.

The operation of the motor causes the sprocket 19 to rotate.
a, 19b and chains 28a, 28b are driven,

[0014]

However, the apparatus for producing hard slag as described above has the following problems. Since the mold 8 is placed on the carriage 9 and moves in the solidification processing chamber 1, the vertical dimension of the solidification processing chamber 1 must be increased. Since the mold 8 is provided with a lid 11 that opens and closes upward to maintain the annealing temperature, it is necessary to secure a work space for opening and closing the lid 11 above the mold in the solidification processing chamber 1. In addition to this, the vertical dimension must be further increased. During operation, the cart 9 is about 1000 to 12 in the solidification processing chamber 1.
Since the caster 14 and the guide rail 7 are used in a severe environment of high temperature maintained in the temperature range of 00 ° C., the casters 14 and the guide rails 7 generate a thermal crack or the like, and maintain a smooth function for a long-time operation. Is difficult. The mold 8 requires opening and closing operations of the lid 11 before and after receiving the molten slag in the solidification processing chamber 1, and after solidifying the molten slag, the mold 8 is suspended and supported by a discharge device (not shown) with the solidified slag inserted. It is conveyed outside, and not only the solidification processing operation but also the unloading operation of the solidified slag after solidification is complicated and time-consuming.

Further, front and rear flanges 66 and 67 are provided on the upper portion of the mold 49, and a slag scattering prevention plate 68 is attached to one of the flanges (here, the rear flange 67). The slag scattering prevention plate 68 has a function of preventing scattering of the molten slag that is continuously dropped when the mold 49 directly below the loading port 56 moves from that position.

The mold 49 has an inverted truncated pyramid shape, and as shown in FIG. 5, rounded portions are provided at boundaries 74 and 75 between the inner surfaces of the front and rear side walls 71 and 72 and the bottom surface 73.
The solidified slag assimilated with the mold 49 by cooling is largely swung at the reversal part at the end of the conveyor, and the boundary parts 74 and 7 are swung.
5 is configured to contact in a gentle state. Thereby, the solidified slag can be prevented from being closely attached to the boundary portions 74 and 75, and the solidified slag can be cleanly dropped at the reversing portion at the end of the conveyor.

The roller chains 43 and 44 are formed such that the roller portions 43 a and 44 a are formed on the left and right side walls 33 and 44 of the solidification processing chamber 32.
Rolls are supported by rails 45 and 46 on both outer sides below and roll along, and move along the slits 35 and 36 of the left and right side walls 33 and 34 of the solidification processing chamber 32. A second rail (not shown) having a predetermined length is disposed on the inner corner side of the bending point above the conveyor line, and the roller chains 43 and 44 are mainly arranged at the bending point. The extension direction is changed by being supported and guided by the second rail.

Must be set to a width as short as the mold 49 can hold the posture, or the radius of the radius at the bending point must be set large. Here, the former is adopted, and the width of the left and right flanges 47, 48 in the traveling direction is set as small as possible.

However, if the widths of the left and right flanges 47 and 48 in the traveling direction are set small, the slits 35 and 36 of the left and right side walls 33 and 34 are opened between the positions where the adjacent molds 49 are attached to the roller chains. Therefore, here, before and after the roller chain mounting position of the mold 49, as shown in FIGS. 3 and 7, the movable seal plate 76 for closing the open portions of the slits 35, 36 is connected to the roller chain 43, 44 to prevent the occurrence of a slit opening. Further, the left and right flanges 47 and 48 on the mold side and the movable seal plates 76 on the roller chains 43 and 44 are also fixed on both outer surfaces of the left and right side walls 33 and 34 of the solidification processing chamber 32 from above and below along the slits. The sealing plates 77, 78 are moved to the crumb members 81, 82.

The liquid is dropped from the charging port 56 and charged into the mold 49. When a predetermined amount of molten slag is charged, the slag conveyor 51 is driven toward the end of the solidification processing chamber 32 and moves by one container. As a result, when the next empty mold 49 comes directly below the loading port 56, the slag conveyor 51
Stops, and the mold 4 stops just below the charging port 56.
In the same manner as above, the molten slag is dropped from the charging inlet 56 into the inside 9 and charged. By repeating this, the subsequent mold 4
The molten slag is sequentially charged into 9 and is moved intermittently (one container at a time) to the end of the conveyor.

In the process of moving the mold 49 into which the molten slag has been charged toward the end of the conveyor, gas is injected into the solidification chamber 32 from gas injection ports 61 provided at a plurality of locations in the longitudinal direction of the solidification chamber 32.

As the gas blowing device, for example, a burner for heating, a nozzle for air for cooling and the like are used, and these are appropriately selected and determined in order to form a zone with a predetermined temperature and gloss.

The slag (solidified slag) which has been crystallized in the mold 49 by cooling or reheating exits the solidification processing chamber 32 with the movement of the mold 49 and enters the conveyer reversal chamber 57 at the terminal where it is moved. Roller chain 43,
When the sprocket 44 is turned over by the sprocket 42, it is separated from the inverting mold 49 by gravity, falls off, is discharged into the hopper 58, cut out, stored in the lower chamber 59, and conveyed out of the system. You.

On the other hand, the mold 4 inverted at the end of the conveyor
Reference numeral 9 denotes a conveyor reversing chamber 6 connected to the base end of the solidification processing chamber 32 through a return path 70 installed outside the solidification processing chamber 32 in accordance with the movement of the roller chains 43 and 44.

Since the inside of the solidification processing chamber 32 is moved in accordance with the movement of the two roller chains 43 and 44, no cart or the like for transporting the mold 49 is required in the solidification processing chamber 32. In addition to being able to compress the vertical dimension of the solidification chamber 32 and using it in a high-temperature environment such as maintaining the inside of the solidification chamber 32 at a slow cooling temperature range of about 1000 to 1200 ° C. during operation, Roller chains 43 and 44, rails 45 and 46,
The generation of thermal cracks and the like on the rails is eliminated, and the service life of these facilities can be extended.

Further, since the mold 49 is configured to be open at the upper end and has no upper lid, it is not necessary to secure a space for opening and closing the lid above the mold in the solidification processing chamber 32. Can be further compressed. Further, not only can the surface temperature of the slag be directly measured by a radiation thermometer or the like, but also the cooling and reheating can be performed directly from the surface of the molten slag, so that the temperature control becomes easy. Therefore, the solidification processing chamber 32 can have a minimum size that allows the molten slag charged in the mold 49 to be cooled and reheated by maintaining the molten slag in a predetermined temperature range for a predetermined time, and is very compact. It can be equipment.

Further, since the slag conveyor 51 is configured endlessly, the solidified slag can be easily dropped and recovered by using the mold reversing portion at the end of the conveyor.
