Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste quality control device used for homogenizing waste sent from a waste hopper to a dust feeder for feeding waste to an incinerator.

[0002]

2. Description of the Related Art Usually, combustible waste such as municipal waste collected by a refuse collection vehicle is transported to an incinerator of a refuse treatment facility and incinerated.

FIG. 7 schematically shows an example of a refuse treatment facility, wherein refuse a carried by a refuse collection vehicle b is first put into a refuse pit c and temporarily stored therein, and then is disposed of. The garbage a in c is grasped by the crane d located above and is thrown into the garbage hopper e.
The refuse a in the inside is supplied to a refuse crusher g by a refuse feeder f such as a conveyor and crushed, and then supplied to an incinerator i by a duster h for incineration.

[0004] The garbage a which is collected and thrown into the garbage pit c may include a bagged one, a large garbage, or a large foreign matter. When the garbage a is transferred to the garbage hopper e, the garbage a is gripped by the crane d, so that the bagged garbage can be broken and mixed with the garbage. Can be crushed by a crusher g, or a crusher h can be crushed by a paddle type.

[0005]

However, in the above-mentioned conventional waste disposal facility, bagging and mixing by grasping the waste a in the waste pit c with the crane d and crushing of the waste a sent to the dust feeder h are performed. Although the garbage a can be crushed in the duster h, the garbage a in the garbage pit c can be lumped all at once even if a large foreign matter is mixed therein. Since the dust hopper e is thrown into the hopper e, there is a possibility that the large garbage a and foreign matter may be caught in the garbage hopper e and clogged. The waste a is no longer supplied to the waste feeder f, and accordingly, the waste a cannot be supplied to the incinerator i, which causes a problem that stable operation cannot be performed. Thrown in When the foreign substance dust a was contaminated, the damage of the blade of the crusher g there is a problem that it becomes hard.

Accordingly, an object of the present invention is to provide a waste quality control device capable of uniforming the quality of waste put into a waste hopper and discharging foreign matter out of the waste hopper.

[0007]

According to the present invention, in order to solve the above-mentioned problems, a plurality of disks provided with blades on the outer peripheral surface are mounted on a shaft at a required interval with the blades having the same direction. Thus, the shaft and the disk can be rotated integrally, and a plurality of disks having different diameters from the above-mentioned disk and provided with blades on the outer peripheral surface are attached to another shaft at a required interval, and the shaft and the disk are rotated. The disks can be integrally rotated, and the shafts are alternately arranged in parallel so that disks having different diameters are arranged in a staggered manner. Both ends of each shaft are rotatably supported by one frame. One end of the shaft is connected to a driving device installed on the frame via a power transmission mechanism to constitute a disk unit that allows each shaft to rotate at the same speed in the same direction. Waste from treatment facility Two sets are mounted on the upper end of the dust hopper so as to cover the upper part of the hopper, and two sets of disk units are arranged so that the blades of each disk face inward, and a foreign matter discharge unit provided outside the trash hopper The drive unit of the disk unit on the side is capable of normal and reverse rotation, and the outer end of each disk unit is attached to the upper end of the dust hopper so as to be tiltable in the vertical direction, and the inner end of each disk unit is moved up and down. A tilting device for tilting in the direction is provided, and the quality of the waste put into the waste hopper is adjusted.

When two sets of disk units are tilted so that the inner side is inclined downward so as to cover the upper part of the dust hopper, when dust is thrown into the disk units from above, first, the size of the disk unit is reduced. The refuse is dropped and supplied to the refuse hopper through a space formed between the adjacent shaft and the adjacent disk. Large garbage is collected at the center of the garbage hopper inside each disk unit by the rotation of the disk in each disk unit.
The dust on the outer peripheral surface of each disk is crushed, and the refuse packed or packed in the bag is broken and unpacked by the blade on the outer peripheral surface of the rotating disk. As a result, the reduced-sized waste is dropped and supplied to the waste hopper through the space, similarly to the small-sized waste described above. On the other hand, large foreign matter mixed in the dust remains on the disk unit without being crushed by the blade of the disk. When foreign matter remains on the disk unit, only the disk unit on the foreign matter discharge unit side provided outside the dust hopper has its axis reversed to rotate each disk outward. As a result, the foreign matter on the disk unit is sent to and removed by the rotating disk toward the foreign matter discharge unit. Also, the disc unit discharges large debris and foreign matters in a state monitored from the outside before the debris is next carried from the debris pit and thrown in, and then the inner end side of the disc unit is tilted by the tilting device. The dust remaining on the disk unit is caused to fall down into the dust hopper by tilting downward. However, when there is little dust remaining on the disk, the dust is stacked on the disk.

Also, instead of mounting disks having different diameters on different shafts and rotating each shaft at the same speed, a disk having the same diameter is mounted on each shaft.
If the configuration is such that adjacent shafts are rotated at different speeds in the same direction, the diameters of the disks attached to the adjacent shafts can be made the same, and there is no need to prepare disks having different diameters.

Further, the cross-sectional shape of each shaft is non-circular except for both ends which are rotatably supported by the frame, the shaft insertion hole of each disk is also non-circular, and a plurality of discs are provided. When the blade of the disk is damaged, only the disk with the damaged blade can be easily replaced if the blade of the disk is damaged. By replacing the spacer with a spacer having a different length, the interval between the disks can be changed, and the upper limit of the size of the refuse supplied to the refuse hopper can be changed.

[0011]

The disk unit I is configured so that the disks 4a and 4b can be simultaneously and rotationally driven in the same direction at the same speed by being transmitted integrally via the shaft 1 together with the shafts 2.

Two sets of the disk units I having the above-described configuration are arranged side by side so as to cover the upper part of a refuse hopper 8 provided in the refuse treatment facility, and the disks 4a and 4b of the two sets of disk units I are disposed. And the outer ends of the two disk units I are attached to the left and right upper ends of the dust hopper 8, respectively.
The disk drive unit is mounted so as to be rotatable (tilted) in the vertical direction via a tilting mechanism so that two sets of disk units can be tilted by a tilting actuator described later, and further provided on one side (right side in the drawing) of the dust hopper 8. The drive unit 13 of the disk unit I on the side of the foreign matter discharge chute 10 is capable of normal and reverse rotation, and by rotating the drive unit 13 in the reverse direction, the disks 4a and 4b of the disk unit I on the side of the foreign matter discharge chute 10 discharge foreign matter. It can be driven to rotate outward in the direction of the chute 10.

When a tilting actuator 17 such as a hydraulic cylinder is used as a tilting actuator for tilting the left and right disk units I, FIG.
As shown in (b), the dust hopper 8 is symmetrically installed at two positions in front and rear of the inner wall surface at the required height, and the distal end of the piston rod 18 of each actuator 17 is attached to the disk unit I of each disk unit I. The tilt actuators 17 are contracted from the state in which the inner ends of the left and right disk units I are pushed up and supported by the respective tilt actuators 17 by being connected to the distal end of the arm 1 a of the frame 1, whereby the tilt actuators 17 are contracted. Each disk unit I is rotated so that the inner end faces downward, and can be tilted to the inside of the dust hopper 8 in a double-opening manner as shown by a two-dot chain line in FIG. .

The blades 5 provided on the outer periphery of the disks 4a and 4b are attached to the outer surfaces of the disks 4a and 4b by welding or brazing. Further, each disk unit I is provided with a cover 19 as shown by a two-dot chain line in FIG. 3 (b), and a chain sprocket 11 for rotating the bearing 3 and each shaft 2;
6. Cover the driving sprocket 15 to prevent dust from entering. Reference numeral 20 denotes a refuse supply device installed below the refuse hopper 8 in the same manner as the refuse supply device f shown in FIG.

When the refuse 21 collected in the refuse pit in the refuse treatment facility is thrown into the refuse hopper 8,
The respective tilting actuators 17 are extended to incline the left and right disk units I so as to have a downward slope toward the inner end side to cover the upper portion of the dust hopper 8, and then the left and right disk units I Each driving device 13
Are driven in mutually opposite directions, and the disks 4a and 4b are simultaneously driven to rotate toward the center of the dust hopper 8 via the power transmission mechanism including the chains 16, 12 and the chain sprocket 11.

In the above state, the refuse 21 in the refuse pit is grasped by a crane, dropped on the disk units I, and once received thereon. Among the dust 21 received on the two disk units I, the dust 21 having a small size is a space 22 formed between the adjacent shafts 2 and between the adjacent disks 4a and 4b for each disk unit I. , And is quickly dropped and supplied to the lower refuse hopper 8.

Next, large-sized dust 21 remains on the disk unit I without being able to pass through the space 22, but dust that can be crushed is separated by the rotating disks 4a and 4b. A crushing action caused by a difference in peripheral speed between adjacent large-diameter discs 4a and small-diameter discs 4b collected at the center side of a dust hopper 8 on the inner end side of the disc unit I and driven to rotate at the same speed in the same direction. Accordingly, the garbage is mainly crushed above the center of the garbage hopper 8, the garbage packed therein is unpacked, and the garbage 21 packed in the bag is subjected to bag breaking processing to reduce the size, and the garbage 21 having a small size is removed. Similarly, the dust is supplied to the dust hopper 8 through the space 22.

On the other hand, large foreign substances 23 which are not crushed and do not pass through the space 22 are left on the disks 4a and 4b of each disk unit I. Disc 4
If foreign matter remains on a and 4b, a foreign matter discharge chute 1

Rotate in the direction. As a result, the disks 4a and 4b of the left and right disk units I rotate in the same direction.
The upper foreign substance 23 is conveyed in the direction of the foreign substance discharge chute 10 and is discharged from the disk unit I to the foreign substance discharge chute 10. After the discharge of the foreign matter 23, the drive unit 13 of the right disk unit I is rotated forward to bring it to an initial state.

Refuse 2 put on the disk unit I
1 is supplied to the dust hopper 8 by a sieving action and a crushing action due to the rotation of the discs 4a and 4b before the next dust is carried by the crane from the dust pit. If the amount of the remaining waste 21 is small, the next waste 21 carried by the crane
By receiving the refuse, the crushing, bag breaking, and unpacking processing of the refuse 21 can be continuously performed.

If the refuse 21 on the disk unit I does not decrease at the time when the refuse in the refuse pit is carried by the crane, the processing of the refuse 21 input while monitoring the disk unit I from outside is performed for a certain period of time. Large size waste 21 which may be clogged in the waste hopper 8
When it is determined that the foreign matter 23 is not mixed in, the tilting actuators 17 are contracted to move the inside of each disk unit I downward as shown by the two-dot chain line in FIG. , And the dust 21 remaining on the disk unit I is quickly dropped into the dust hopper 8. After that, the tilting actuator 17 is extended to rotate each disk unit I upward to return it to the initial state, and then the rejection of the dust 21 onto each disk unit I is resumed, whereby the dust 21 is crushed. ,
The bag breaking, the unpacking process, and the process of discharging the foreign matter 23 can be performed subsequently.

As described above, the dust 21 dropped and supplied to the dust hopper 8 is received at a position above the dust hopper 8 and crushed, broken, and unpacked to reduce the size of the dust 21 to the space 22.
And the foreign matter 23 can be sent to the foreign matter discharge chute 10 and removed therefrom, so that the quality of the waste 21 supplied to the waste hopper 8 can be uniform. It is possible to prevent clogging in the refuse hopper 8 and to stably supply the refuse 21 to the furnace body, thereby stabilizing the operation of the refuse treatment facility. Can be. In addition, it is possible to prevent the foreign matter 23 from being thrown into the crusher provided downstream of the dust hopper 8, and to prevent damage to the blade of the crusher.

In the present invention, the discs 4a, 4b and the spacer 7 are fitted to the shaft 2 so as to restrict the rotation, and can be easily removed from one end of the shaft 2. If the blade 5 on the outer periphery of the disk 4a or 4b is damaged, only the damaged disks 4a and 4b of the blade 5 can be easily replaced.
Also, by replacing the spacers 7 disposed between the disks 4a and 4b on all the shafts 2 with spacers 7 having different lengths, the disks 4a on the shafts 2 are connected to each other.
The interval between the two can be changed, and the size of the formed space portion 22 can be changed. As a result, the upper limit of the size of the refuse 21 supplied to the refuse hopper 8 can be changed.

When the combustible dust 21 which is hardly bound and hardly crushed is discharged together with the foreign matter 23 from the foreign matter discharge chute 10, the waste discharged from the foreign matter discharge chute 10 is removed. The worker sorts the above garbage 2
1 may be appropriately collected, crushed to a required size, and then re-entered into the garbage pit.

Because the number of teeth of the sprockets 11a and 11b are different,
The rotation speed can be changed for each adjacent shaft 2, and the rotation speed of the disk 4 attached to each adjacent shaft 2 can be changed, so that the blades 5 of the disk 4 adjacent in the rotation direction can be crushed. The function can be obtained, and the crushing, breaking of the bag, unpacking processing, and removing processing of the foreign matter 23 can be performed. Also in this embodiment, the drive unit 13 of the disk unit I on the side of the foreign matter discharge chute 10 (see FIGS. 1 and 4) can be driven forward and reverse. The foreign matter discharge chute 10 is rotated.

At the same time, a tensioning sprocket 30 is provided between the chain sprockets 11 so as to engage the chain 29 from the outside, so that one chain 29 and the chain sprocket 11 are securely engaged with each other. Are driven to rotate in the same direction. FIG.
(B) is to provide a gear 31 on each shaft 2 and to interlock with each other by interposing a power transmission gear 32 between the gears 31;
A gear 31 provided on the shaft 2 on the side of the driving device 13 is meshed with an output gear 34 in a gear box 33 attached to the output shaft 14 of the driving device 13 so that power from the driving device 13 is transmitted to each gear. The shafts 2 are transmitted via 31 and 32 to rotate the shafts 2 in the same direction at the same speed.

It should be noted that the present invention is not limited to only the above-described embodiment, and is shown in FIGS.
In (b), six discs 2 are arranged in each disk unit I, but only the dust 21 of a desired size to be put into the dust hopper 8 is passed between the adjacent spindles 2. If the space 22 to be formed can be formed, the shaft 2
2 (a) and 2 (b) show that the shaft 2 is shaped like a square bar and the disks 4a and 4b are fitted so that the rotation direction is restricted. The present invention is not limited to this, as long as the disks 4a and 4b can be rotated integrally with the shaft 2. For example, the disks 4a and 4b may be non-circular shafts such as splines, and the disks 4a and 4b May be provided with a grooved shaft insertion hole corresponding to the spline,
Also, the case where the individual disks 4a and 4b can be removed from the shaft 2 has been described. However, if the individual disks 4a and 4b are to be removed and replaced for each shaft 2, the shaft 2 and the disks 4a and 4b are fixed via a key. What can be done, FIG. 1
(A) and (b) show the case where the foreign matter discharge chute 10 is installed only on one side of the dust hopper 8, but if the foreign matter discharge chute 10 can be provided on both left and right sides of the dust hopper 8, the foreign matter 2
