Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste feeder for receiving waste stored in a waste pit of a waste treatment facility and supplying the waste in a fixed amount for incineration.

[0002]

2. Description of the Related Art In a waste treatment facility, as shown in the outline of an example in FIG. 5, waste transported by a waste truck 1 is put into a waste pit 3 from a waste input port of a platform 2 and stored. And store it for a certain period of time, then
Is grabbed by the bucket 6 of the waste crane 5 and lifted from the inside of the waste pit 3 into the hopper 8 of the waste feeder 7, and then fixed by the apron conveyor 9 installed below the hopper 8 of the waste feeder 7. After being supplied and further crushed by the dust crusher 10, the dust carrier 1 conveys the dust 1
It is conveyed to No. 2 and supplied from the dust feeder 12 into an incinerator (not shown) for incineration.

As shown in FIGS. 6 and 7, a dust feeder 7 used for receiving and quantitatively feeding the dust 4 picked up from the dust pit 3 is provided at the bottom of the hopper 8 at the front end thereof. Has a discharge port 13 on the lower surface of the
Apron conveyor 9 designed to convey waste in the direction of
A casing 14 having a built-in is installed, and the waste that is received in the hopper 8 and is located on the apron conveyor 9 is moved to the discharge port 13 side by the apron conveyor 9 to remove the waste in the hopper 8. The apron conveyor 9 is moved and sequentially moved onto the apron conveyor 9 so that the apron conveyor 9 feeds it through the throat portion 15.

Reference numeral 16 denotes a discharge port 1 rather than the throat portion 15 of the feeder 7.
3 is a feeding drum provided in the vicinity of 3, a driving mechanism of an apron conveyor, 17a is a sprocket attached to both ends of a pulley 17b of the apron conveyor 9, 17c is a chain, and 17d is a motor with a reduction gear.

[0005]

However, in the operation of the above-described conventional dust feeder, the dust in the hopper 8 is discharged from the discharge port 13 by automatically driving the apron conveyor 9 in response to a dust request from the dust feeder 12. Although the waste is sent out and supplied to the dust feeder 12, if the apron conveyor 9 is started in a state where the hopper 8 receives the waste, the waste on the apron conveyor 9 is removed. The apron 9a of 9 starts to move and reaches the throat portion 15 of the feeder 7. At this time, if a large amount of dust in the hopper 8 on the apron conveyor 9 is pulled by the apron conveyor 9 and moved in the direction of the throat 15 all at once, the dust is compacted in the throat 15 of the feeder 7. It goes into a state. At this time, the rotation of the feeding drum 16 and the movement of the apron conveyor 9 can send out a certain amount of dust, but the apron conveyor 9
The upper dust of the throat 15 moves toward the throat 15 by the movement of the apron conveyor 9 until it reaches the vicinity of the throat 15, whereby the amount of dust in the throat 15 gradually increases and is finally consolidated. The amount of dust increases, clogging of the dust occurs in the throat portion 15, and the transport becomes impossible. This trend is
This occurs when the dust is bulky or when a large amount of dust is put in the hopper 8.

Therefore, according to the present invention, even if dust is bulky in the hopper or a large amount of dust is thrown into the hopper, clogging of dust in the throat of the feeder is continuously eliminated. It aims to be able to supply.

[0007]

According to the present invention, in order to solve the above problems, a conveyor is installed in a casing connected to the bottom of a hopper, and dust inside the hopper can be moved by driving the conveyor to move the throat. To limit the supply of waste that is moved by the movement of the conveyor to the position near the throat at the bottom position of the hopper in the waste supply device of the waste treatment facility that is passed through and supplied. Rods are attached in a horizontal direction orthogonal to the moving direction of the conveyor, and further, the mounting position of the dust feed limiting rod is at the height of the throat and the dimension apart from the throat is opposite to the hopper wall surface. The distance is set to about 1/10 of the distance between them, or both ends of the refuse supply limiting rod are rotatably supported and attached to the hopper wall.

When the conveyor is moved, the debris in the hopper above the conveyor is moved by the movement of the conveyor and along with the conveyor toward the throat. At this time, the garbage is divided into upper and lower parts by hitting the refuse supply restriction rod, and the waste on the waste supply restriction rod is escaped upwards and the waste lower than the refuse supply restriction rod is supplied. The trash will be compacted and will not clog.

Further, by rotating the refuse supply limiting rod, it becomes possible to more smoothly separate the refuse into upper and lower parts.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention. In the refuse feeder having the same structure as the conventional refuse feeder 7 shown in FIGS. 6 and 7, the bottom of a hopper 8 is provided. At a position close to the throat portion 15, the apron conveyor 9 is moved by a hollow or pipe-shaped refuse supply limiting rod 18 for limiting the supply of the refuse 4 which is moved by the apron conveyor 9 to be supplied. It is arranged in the horizontal direction orthogonal to the direction so that both ends are attached to the hopper 8.

As the mounting position of the dust supply limiting rod 18 mounted near the throat portion 15, the throat portion 1 of the feeder 7
5 is at the same height as the position of 5 and is away from the throat portion 15 by a required distance rearward, that is, about 1/10 to 8 minutes of the interval of the level of the throat portion 15 in the front-back direction (moving direction of the apron conveyor). 1st position of For example, when the distance in the front-rear direction is 3 m, the position is 30 cm away from the throat portion 15.

As shown in FIG. 3 (a), the dust supply limiting rod 18 is attached to the inner wall surface of the bottom of the hopper 8 as shown in FIG. 3 (a). 3 or (b), or by attaching plate-like attachment members 19 to both ends of the dust supply limiting rod 18, and attaching the attachment members 19 to the inner wall surface of the hopper 8. The refuse supply limiting rod 18 is attached by fixing the same to the above with bolts or welding.

When the refuse supply limiting rod 18 is horizontally attached at the level position of the throat portion 15 of the waste feeder 7 and near the throat portion 15, the dust 4 thrown into the hopper 8 becomes bulky. Even if a large amount of waste is put into the hopper 8, the apron conveyor 9 starts to move based on the command, so that the dust existing above the apron 9a of the apron conveyor 9 moves by the movement of the apron 9a. The dust on the apron conveyor 9 is sequentially moved toward the throat 15 by the apron conveyor 9 by the continuous operation of the apron conveyor 9 by being pulled in the moving direction and starting to move. At this time, due to the presence of the dust supply limiting rod 18, some of the dust 4 that is moved in the direction of the throat portion 15 is divided up and down by the dust feeding limiting rod 18, and Only the dust that has entered below reaches the throat portion 15 as the apron conveyor 9 moves,
Further, it passes through the throat portion 15 and is sent to a position above the discharge port 13. On the other hand, the trash 4 divided above the trash supply limiting rod 18 is pushed and moved in the direction of the arrow as shown in FIG. 1, so that the trash 4 can be reversed together with the movement of trash passing under the trash supplying limiting rod 18. become.

In this way, the dust on the apron conveyor 9 is moved along with the movement of the apron conveyor 9 and the throat portion 1 is moved.
Before the compaction occurs in 5, the dust can be applied to the dust supply limiting rod 18 and divided into the upper and lower parts so that the upper dust can escape. Therefore, the dust 4 is not compacted in the throat portion 15 and does not cause clogging, so that the continuous feed Is possible.

Next, FIG. 4 shows another embodiment of the present invention in which the refuse supply limiting rod 18 is rotatably attached to the feeder 7. (a) (b) (c) Both show different mounting methods.

That is, in FIG. 4 (a), the recesses 20 are provided on the inner wall surfaces of the bottom of the hopper 8 of the feeder 7 so as to face each other, and both ends of the dust feed limiting rod 18 are provided in the recesses 20 via bearings 21. Is rotatably supported and attached.

In FIG. 4B, instead of providing the recess 20 on the inner wall surface of the hopper shown in FIG. 4A, a support member 22 having a recess shape is fixed to the inner wall surface of the hopper so as to face each other. Both ends of the dust feed limiting rod 18 are rotatably supported and attached to the support member 22 via bearings 21.

In FIG. 4 (C), through holes 23 are provided on the wall surface of the bottom of the hopper 8 so as to face each other, and the bearings 21 are provided in both through holes 23.
Both ends of the dust feed restricting rod 18 are rotatably supported via the above, and the sealing plate 24 is fixed to the outer wall surface of the hopper 8.

In any of the above-mentioned methods, since the refuse supply limiting rod 18 can rotate, when the dust in the hopper 8 which starts to move due to the movement of the apron conveyor 9 hits the dust supply limiting rod 18,
The refuse supply limiting rod 18 can be arbitrarily rotated upward or downward, so that the refuse 4 can be more easily divided into upper and lower parts and the movement of the refuse can be smoothed.

Further, in any of the above-mentioned methods of FIG. 4 (a), (b) and (c), it is possible to rotate the juice of the dust 4 in the feeder 7 without flowing it out. .

[0022]

As described above, according to the waste feeder of the waste treatment facility of the present invention, the conveyor is installed in the casing connected to the bottom of the hopper, and the waste in the hopper can be moved by driving the conveyor. In a waste feeder of a waste treatment facility that is fed through the throat and supplied, a waste supply that is moved by the movement of the conveyor to a position near the throat at the bottom position of the hopper is provided. The bar for limiting is configured to be attached in the horizontal direction orthogonal to the moving direction of the conveyor, and the size of the attachment position of the dust feed limiting rod at the height position of the throat and away from the throat. Since the distance between the opposing hopper wall surfaces is about one-tenth, and both ends of the refuse supply limiting rod are rotatably supported and attached to the hopper wall, the apron conveyor is driven. When the waste on the apron conveyor is moved and supplied, the waste supply is restricted by the waste supply restriction rod provided in the hopper near the throat, and the waste that escapes above the waste supply restriction rod moves to above the hopper. Since it is possible to move it and only the dust under the dust feed restriction rod can be fed toward the throat, it is possible to prevent dust from being compacted and blocked in the throat, and to stabilize the quantitative determination continuously. The excellent effect of being able to be supplied can be obtained, and by making the rod rotatable, the excellent effect of being able to flow dust more smoothly upward or downward can be obtained.
