FIG. 4 is a schematic side view showing a basket in the powder or granular material discharging device of FIG. 1, which is an embodiment of the basket for the powder or granular material discharging device of the present invention.
2 is a sectional view taken along the line BB of FIG. 2, FIG. 6 is a perspective view showing the opening / closing drive device in the basket of FIG. 4, FIG. 7A is a front view of the opening / closing drive device of FIG. 6, and FIG. FIG. 7 is a side view of the opening / closing drive device of FIG. 6.

In the discharging device 1 shown in FIGS. 1 to 3, 2 is a traverse carriage, and 3 is an elevator carriage (corresponding to a basket carrier truck in claims). Wheels 4 on the traverse truck 2
2 can be moved in the direction perpendicular to the plane of FIG. 2 on the first rail 5 laid in the workplace where the discharge device 1 is installed. Of course, depending on the total weight of the vehicle, the vehicle may be allowed to move by an endless track or tire mounted wheels without laying a rail. Further, a second rail 6 is laid on the upper surface of the traverse vehicle 2 perpendicularly to the traveling direction of the traverse vehicle 2, and the elevator truck 3 having wheels 7 can be moved on the second rail 6. A basket 8 for accommodating the converter slag is arranged on the lift truck 3. Therefore, the basket 8 can be moved to an arbitrary position by the combination of the movements of the traverse carriage 2 and the lifting carriage 3. A bridge rail 9 continuous with the second rail 6 is tiltably attached to the side end of the transverse carriage 2. The bridge rail 9 is a rail used when moving the lifting carriage 3 between the traverse carriage 2 and the inside of the autoclave 10 (see FIG. 2). 11 is a traverse truck 2
Is a first motor for moving forward and backward, and 12 is a second motor for moving forward and backward the lift truck 3.

Reference numeral 10 denotes the above-mentioned autoclave, which is a so-called pot for reforming the slag. 1 to 3, reference numeral 13 is an elevating device mounted on the elevating carriage 3.
The basket 8 is driven to move up and down by a hydraulic cylinder. Further, 14 is a mounting table installed on the traversing carriage 2, and is for mounting the basket 8 when the basket 8 is lowered by the elevating device 13.
Further, on the traversing carriage 2, four opening / closing drive devices 15 for opening and closing the opening (the discharge port 23 in FIGS. 4 and 5) below the basket 8 are installed.

Although not shown, both the lifting carriage 3 and the traverse carriage 2 are formed with openings below the basket 8 so that the granular material can fall. That is, both the lifting carriage 3 and the transverse carriage 2 are formed as rectangular frames.

The basket 8 is shown in more detail in FIGS. 4 and 5. The basket 8 is composed of a tubular main body 16 having a substantially octagonal cross section, and a frame member 17 supporting the main body 16. The main body 16 has a pair of semi-cylindrical members 18a, 18b cut along a plane along the axial direction thereof.
It is composed of Each of the half-cylindrical members 18a, 18b has a closing plate 19a, 19b for closing both ends thereof. In addition, the upper part of the main body 16 (both half cylinder members 18a, 1
The space between the upper ends of 8b) is open and serves as a filling port 20 (see FIG. 5) for the granular material. The half-cylindrical members 18a and 18b are provided with bearing columns 21a and 21b that are erected on the frame member 17 at slightly upper portions of the closing plates 19a and 19b.
Are rotatably supported by common shafts 22a and 22b.

Therefore, when the half-cylindrical members 18a, 18b are rotated outward and upward by the opening / closing drive device 15 about the shafts 22a, 22b, the lower part of the main body 16 is opened and the powder granules are dropped or discharged. An outlet 23 (see Fig. 5) is formed.

The opening / closing drive device 15 is provided with a hydraulic cylinder 24 as shown in FIG. 3 and FIG.
The mounting table 14 is rotatably mounted upward at a position corresponding to both sides of the lifting carriage 3 (both sides of the basket 8).

Reference numeral 25 is a bellows for dust prevention. The roller 2 is attached to the tip of the spreader 24a of the hydraulic cylinder 24.
6 is rotatably mounted. The rollers 2 are respectively provided on the outer surface of each of the half-cylindrical members 18a and 18b of the basket 8 corresponding to the spreader 24a.
An engaging member 27 having a semi-cylindrical groove 27a (see also FIG. 7) which is open downward and can be engaged with 6 is fixed. Then, when the spreader 24a is extended upward, the roller 26 engages the engaging member 27 with the groove 27a and pushes it up, so that the two semi-cylindrical members 18a and 18b are connected to the shafts 22a and
It is rotated about 2b and pushed open to both sides (open the discharge port 23). Since the hydraulic cylinder 24 is rotatably attached, it can easily follow the arc movement of the engaging member 27 due to the rotation of the half cylinder member. On the other hand, when the spreader 24a is contracted, both the half cylinder members 18a, 18
b is rotated back to its original position by its own weight, and the lower discharge port 23 is closed.

As described above, the opening of the basket 8 by the opening / closing drive device 15 includes the roller 26 and the semicylindrical groove 27a.
It begins with the engagement with. Therefore, the engagement between the roller 26 and the semi-cylindrical groove 27a is centripetal, so to speak, due to the mutual shape effect, and even if the slight displacement between the basket 8 and the transverse carriage 2 is in any direction. It is securely engaged.

Further, since the spreader of a normal hydraulic cylinder is rotatable about its own axis, in the present embodiment, the spreader 24a is provided with a guide for preventing rotation. As shown in FIGS. 6 and 7, this guide element is composed of a pair of guide rollers 28 rotatably attached to both sides near the attachment portion of the roller 26. On the other hand, a pair of guide plates 29, which guide the rolling of the guide rollers 28 when the spreader 24a expands and contracts, are fixed to the mounting table 14 of the hydraulic cylinder. Therefore, the spreader 24a has guide rollers 28 on both sides thereof.
Contacts the guide plate 29, so that rotation around its own axis is prevented. Then, once the roller 26 has the semi-cylindrical groove 27a.
The groove 27a, the spreader 24a
Since the rotation of the guide plate 29 is suppressed, the function of the guide is not necessary.
The length is just before engaging with. Therefore,
After the roller 26 is engaged with the groove 27a, the basket body 1
6 When the spreader 24a extends so as to open the lower discharge port 23, the guide plate 29 is no longer attached to the hydraulic cylinder 2.
It does not hinder the inclination of 4. Furthermore, the guide plate 29
Since the guide surface 29a of the is inclined so as to open to the outside of the basket in the vicinity of the upper end (shown by 29b in FIGS. 6 and 7), the roller 26 and the upper end of the guide plate 29 are contracted when the spreader 24a is contracted. You won't get caught.

On the other hand, as shown in FIGS. 6 and 7, the hydraulic cylinder 24 is rotatably attached to the support column 25 by a shaft 30, and the pair of guide plates 29 are also mounted on the mounting table 1.
4 attached. Here, in both of the guide plates 29, the upper and lower two positions of the L-shaped base are made into the disc springs 31.
The bolt 31b is elastically secured by interposing a. Therefore, both guide plates 29 can be elastically swung by a slight distance in the direction of arrow CD in FIG. 7B. As a result, even if there is a slight displacement between the basket 8 and the traverse carriage 2, that is, even if the engagement member 27 is displaced with respect to the roller 26 of the hydraulic cylinder, the hydraulic pressure in that case is changed. The guide plate 29 can easily follow the inclination of the cylinder 24, and
Since the restoring force that always elastically returns to the original inclination (usually the vertical direction) is working, the roller 26 and the engaging member 2
The guide plate 29 has already returned to the vertical state at the time when it is engaged with 7, that is, when the contact between the guide roller 28 and the guide plate 29 is released.

Next, as shown in FIGS. 4 and 5, each of the half-cylindrical members 18a, 18b constituting the basket body 16 is formed.
Is pivotally supported by the bearing columns 21a and 21b as described above, but not only that, but the lower portion thereof is supported by the four support rollers 32 installed on the frame member 17. An arcuate rail plate 33 on which the support rollers 32 roll relative to each other is provided on the bottom surface of each of the half cylinder members 18a and 18b.
a and 33b are laid. This arc-shaped rail plate 3
Naturally, 3a and 33b are formed in an arc shape centered on the shafts 22a and 22b. Therefore, the opening / closing drive device 15
When the two half-cylindrical members 18a and 18b are rotated (the main body 16 is opened and closed) by the support roller 32
Supports the weight of the main body 16 while rolling on the rail plates 33a and 33b relatively. The shafts 22a and 22b may support a part of the weight of the main body 16.

As described above, the discharge port 23 of the main body 16 is opened by the expansion of the spreader 24a of the hydraulic cylinder, and is closed by its own weight when the spreader 24a is contracted. As is apparent from FIG. 4, the center of gravity of each of the half-cylindrical members 18a and 18b is largely displaced in the horizontal direction from the shafts 22a and 22b serving as pivot points, so that a sufficient closing force is generated and the supporting roller 32 is caused by its own weight. Since it is pressed by and becomes resistance,
The discharge port 23 does not open carelessly due to the weight of the granular material inside.

Further, as shown in FIG. 5, a stacking plate 34 for preventing the slag in the basket 8 from leaking out when the discharge port 23 is closed is provided. The stacking plate 34 is disposed near the inner side of the bottom edge of one of the half-cylindrical members 18a and 18b (in this embodiment, the left half-cylindrical member 18a) that constitutes the discharge port 23 of the main body 16, and the both half-cylindrical members 18 are formed.
It is arranged so as to cover the abutting edges of a and 18b.

According to the above basket 8, for example,
Effective work can also be performed by directly installing the basket 8 on the traverse vehicle 2 without using the lifting cart 3.

Although the hydraulic cylinder is used as the opening / closing drive device in the above embodiments, the invention is not limited to the hydraulic cylinder, and for example, an electric cylinder or a pneumatic cylinder may be used.

Next, an example of the operation of the above-mentioned discharge device 1 will be described with reference to FIGS.

First, the transverse carriage 2 is moved to a predetermined position while the basket 8 and the lift carriage 3 are placed (see FIGS. 1 to 1).
3). At this time, the lifting device 13 of the lifting carriage 3 is lowered to place the basket 8 on the mounting table 14 on the transverse carriage 2 (FIG. 2). Then, the converter slag is filled into the basket 8 through the filling port 20 at the upper end of the basket 8. In this state, the traverse vehicle 2 is moved to the front of the entrance hatch 10a of the autoclave 10 (Fig. 2). Then, the entrance hatch 10a of the autoclave 10 is opened, the bridge rail 9 on the traverse carriage 2 is suspended over the entrance 10a of the autoclave 10, and the second rail 6 on the traverse carriage 2 is attached to a rail (not shown) in the autoclave 10. (Fig. 2). Then, the elevating device 13 of the elevating carriage 3 is lifted, the basket 8 is lifted from the mounting table 14 and pushed up in a state of riding on the elevating device 13 (two-dot chain line in FIG. 2). In this way, the basket 8 is cut off from the transverse carriage 2, and then the lift truck 3 with the basket 8 placed thereon is moved on the rails of the transverse carriage 2 and loaded into the autoclave 10. Then, the basket 8 is placed or gripped on a mounting table (not shown) in the autoclave 10 and only the lifting carriage 3 is returned onto the traverse carriage 2. After that, the hatch 10a of the autoclave 10 is closed, and heating and pressure treatment with steam for a predetermined time are performed. After that, the hatch 10a is opened, and the lift truck 3 is again set in the autoclave 1
0, the basket 8 is placed on the elevating device 13, the elevating carriage 3 is returned to the traverse trolley 2, and then the bridge rail 9 is tilted upward and retracted to complete the reforming work. Then, the elevating device 13 is lowered, and the basket 8 is placed on the mounting table 14 on the traverse carriage 2 again (FIG. 2).
Is moved to the specified discharge location. Then, the hydraulic cylinder 24 of the opening / closing drive device 15 is operated to open the basket body 16 (two-dot chain line in FIGS. 4 and 5), and the modified powder or granular material is dropped from the discharge port 23 and discharged. .

In the above embodiment, the discharge device for reforming the converter slag has been described, but the present invention can also be applied to, for example, a sediment transport discharge facility at a construction site such as tunnel excavation. it can.

[0043]

According to the discharging device of the present invention, the powder and granules can be filled in the basket on the carriage and conveyed, and the lower part of the basket is opened as it is at almost any place, and the internal powder and granules are weighed by its own weight. Since it is dropped downward by means of, the degree of freedom of installation of the device is high, and the device itself can be simplified. That is, it is not necessary to remove the basket and attach it to another discharging device. Therefore, the automation of the discharging work can be inexpensive.

Further, according to the basket of the present invention, the discharge port is easily formed in the lower portion only by pushing up both side portions of the main body by the driving device.
