DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag breaking device for a garbage pit in a garbage disposal plant, and more particularly, to breaking a garbage bag put in a garbage pit before putting it into facilities such as an incinerator and a sorting machine. In addition to making it easier to stir and mix garbage, it is possible to homogenize the garbage, reduce the moisture contained in the garbage, increase the combustion efficiency, and continuously and uniformly incinerate the garbage The present invention relates to a waste pit bag-breaking device for a refuse treatment plant, which can suppress generation of harmful substances such as dioxin accompanying incineration of refuse.

[0002]

2. Description of the Related Art Conventionally, refuse discharged from general households and the like is collected by a refuse collection truck, carried into a refuse incineration plant, and incinerated. By the way, in a conventional refuse treatment plant, refuse collected by a refuse collection vehicle is once introduced into a garbage pit, and the required stirring and mixing is performed using a garbage charging crane in the garbage pit. It was to be thrown into a hopper for incineration.

[0003]

However, the garbage collected by the garbage truck is often in a bag.
Performing the required stirring and mixing using the bucket of the garbage crane alone does not break the garbage bag, which limits the homogenization of the garbage. Due to the difference in the amount, especially in small stoker type incineration equipment, the unevenness of combustion inside the stalker becomes remarkable, so the combustion speed of refuse in the incinerator, the amount of generated heat fluctuates, the incineration temperature changes greatly, There has been a problem that harmful substances such as dioxin are easily generated. That is, in a small stoker-type incinerator of 100 to 200 tons / day, the width of the stalker is at most about 2 m, and if a garbage bag of 0.4 to 0.5 m is included in the stalker, the stalker will be sufficiently localized. The refuse that is not dried is sent to the combustion stalker, and harmful substances such as dioxin are easily generated.

[0004] To cope with this, refuse collected by a refuse collection truck is preliminarily stirred and mixed by using a stirring and mixing facility such as a bag breaking device for breaking the refuse bag, thereby homogenizing the refuse, and providing an incinerator. It is also possible to reduce the amount of harmful substances such as dioxin generated at the time of starting and stopping due to operation interruption by enabling long-term operation, but this stirring and mixing equipment not only increases the equipment cost, Due to its large size, it is difficult to install it in the garbage pit of the garbage disposal plant.Therefore, it is necessary to transport the garbage between the garbage pit and the stirring and mixing equipment. There was a problem in point.

[0005] In view of the above-mentioned problems of the conventional waste disposal plant, the present invention breaks a waste bag put into a waste pit before putting it into a facility such as an incinerator or a sorting machine. In addition to facilitating the mixing and mixing of the garbage, it is possible to homogenize the garbage, and the moisture enclosed in the garbage bag is discharged together with the garbage, thereby making the garbage continuous and uniform. An object of the present invention is to provide a bag-breaking device for a garbage pit in a garbage disposal plant, which enables incineration and suppresses generation of harmful substances such as dioxin accompanying incineration of the garbage.

[0006]

In order to achieve the above object, a bag breaking device for a garbage pit in a garbage disposal site according to the present invention is provided with a moving device capable of traveling and traversing above a garbage pit in a garbage disposal site. A dust-breaking device for a garbage pit, wherein the lifting device provided in the moving device is provided with a bag-breaking machine for breaking up a garbage bag in a garbage pit so that the bag-breaking machine can move up and down. A rotary blade having a rotary drive shaft to which blades are attached at predetermined intervals is provided substantially horizontally, and a rotary bag-breaking blade is provided.

This bag breaking device for a refuse pit in a refuse disposal site travels and traverses a moving device installed so as to be able to run and traverse above the refuse pit in the refuse disposal site, and distributes it to the moving device at a required position. A lifting machine is installed on the lifting device, and a bag breaking machine arranged to be able to move up and down is installed on the bag breaking machine in a substantially horizontal direction. A rotary drive shaft with a plurality of bag breaking blades attached at predetermined intervals is rotated. By lowering the garbage in the garbage pit from above, the garbage bag in the garbage pit can be broken and sheared, so that the garbage inside and outside the garbage bag can be easily mixed. Further, it is easy to stir and mix the refuse by a refuse input crane or the like, so that the refuse can be homogenized and the moisture contained in the refuse can be uniformed.

In this case, a plurality of small-diameter bag-breaking disk-shaped blades are attached to the bag-breaking machine at predetermined intervals, and a plurality of rotating-drive shafts for the same-diameter or larger-diameter bag-breaking. Rotating drive shafts with disk-shaped blades attached at predetermined intervals are arranged in parallel, for rotating bags with the same diameter or larger diameter as the rotating drive shaft with the small-diameter disk-shaped blades for bag breaking. A rotary drive shaft with a disk-shaped blade attached is attached in the same direction, and a disk-shaped blade for bag-breaking of the same diameter or large diameter is attached from the rotary drive shaft side with a small-diameter disk-shaped blade for bag-breaking attached. It can be configured to be driven to rotate in the direction of moving to the rotating drive shaft side.

Thus, the refuse bag is fed from the side of the rotary drive shaft on which the small-diameter disk-shaped blade for breaking bags is attached to the side of the rotary drive shaft on which the disk-shaped blade for breaking bags of the same diameter or large diameter is mounted. A wide range of bag-breaking operations can be performed efficiently without moving the bag-breaking machine, and it is possible to make it difficult for debris or garbage bags to adhere to the disk-shaped blade for bag-breaking. Can be performed stably.

[0010] The swinging blade may be configured so that the swinging rod has a swinging-type bag-breaking blade facing the rotary bag-breaking blade.

Thus, the oscillating bag-breaking blade is swung according to the size of the garbage bag, and the distance between the rotary bag-breaking blade and the oscillating bag-breaking blade is adjusted. Can be changed freely, so that garbage bags of different sizes can be reliably sheared, and the breakage of the device can be prevented. Entangled debris and litter bags can be removed by a swinging bag-breaking blade.

[0012] Further, a column can be provided on the lower surface of the bag breaking machine.

Accordingly, when the bag-breaking machine descends on the refuse, it maintains its levelness, and in particular, the rotary-type bag-breaking body blade rotates to move the bag-breaking machine. , Can be prevented from vibrating.

[0014] Further, it is possible to control the traversing and traveling of the moving device and the elevating operation of the elevating device based on the information of the related equipment and the information from the bag breaking machine.

[0015] Thus, the bag breaking operation can be performed efficiently without interfering with the related facilities such as a crane for charging garbage.

It is configured to be rotationally driven in the direction of moving to the side of the It is desirable to. Further, in the present embodiment, four blade edge pieces 20a and 21a are provided on the outer peripheral edges of the disk-shaped blades 201 to 208 and 211 to 218 for bag breaking, respectively, but the blade edge pieces 20a and 21a are provided.
The number and the shape of “a” are not limited to this, and can be changed as appropriate in accordance with the characteristics of the garbage that differs for each region. The cutting edge pieces 20a and 21a provided on the outer peripheral edges of the rotary bag-breaking blades 20 and 21 are used as the disc-breaking blades 201 for bag-breaking.
To 208, 211 to 218, or separately manufactured, and fixed to the disk-shaped blades 201 to 208, 211 to 218 for welding by welding, bolts or the like.

In this case, the rotary blade 2 for bag breaking is used.

And the disk drive blades 211 to 218 for the bag breaking are arranged such that the adjacent disk blades 201, 211 to 208, 218 for the bag break on one side are close to each other and overlap each other. 20S and 21S are provided.

A cable basket 13, a driving motor 17 and an inclinometer 19 are respectively disposed above the main body frame 80 of the bag breaking machine 8, and the driving force of the driving motor 17 is reduced by the speed reducer 18 and the sprocket wheel. , A drive shaft 20S of each of the rotary bag-breaking blades 20, 21 via an arbitrary power transmission mechanism 24, 25 comprising a chain or the like.
21S so that the drive shafts 20S and 21S rotate in the same direction.

As described above, the rotary bag-breaking blades 20, 2
1, the bag-breaking blades 20, 21 are inserted to a predetermined depth of the refuse introduced into the refuse pit 1 by the weight of the crushing machine 8, thereby shearing the refuse bag and removing the refuse. Stirring can be performed. In particular, the cutting edge pieces 20a and 21a formed on the outer peripheral edges of the bag-shaped disk-shaped blades 201 to 208 and 211 to 218 finely shear the synthetic resin-made garbage bag, which is difficult to break, so as to tear it. In this way, the bag breaking operation can be performed efficiently. In addition, the rotary bag-breaking machine in which the garbage bags are attached with the large-diameter disc-cutting blades 211 to 218 from the side of the rotary bag-breaking blade body 20 to which the small-diameter disc-cutting blades 201 to 208 are attached. Since it is sent to the blade 21 side, it is possible to efficiently perform a wide range of bag breaking work without moving the bag breaking machine 8, and the sheared garbage and the garbage bag are used for the bag breaking blade. Due to the rotational force of the body 21, the dust is blown to the rear of the bag breaking machine 8, and the garbage is agitated and mixed.
Garbage and a garbage bag can be made hard to adhere to 1 to 218, and the bag breaking operation can be performed continuously and stably.

The columns 30, 31, 32, and 33 provided at the four corners on the lower surface of the main body frame 80 of the bag breaking machine 8 are supported by the lifting device 6 via the ropes 7 so as to be suspended vertically. When the machine 8 descends on the refuse, while maintaining the levelness, the rotation of the rotary bag-breaking blades 20, 21 prevents the bag-breaking machine 8 from moving or vibrating. In addition to preventing, when falling on sloping garbage,
It has a function of preventing the bag breaking machine 8 from being stabbed by dust and tilting.

Next, the operation and operation of the bag-breaking device for a garbage pit in the garbage disposal site will be described. Garbage near the pit entry gate 14 collected by the garbage collection vehicle and introduced from the pit entry gate 14 is transferred to the garbage crane 1.
5 is used for transshipment. As a result, the current position and the movement schedule information of the refuse input crane 15 are received from the control device 10, and the position (address) for performing the bag breaking operation is determined while avoiding interference with the refuse input crane 15. In this case, an interlock with the refuse input gate 14 can be taken if necessary.

When the girder 3 and the moving device 5 of the bag breaking device A travel or traverse, the waste level information in the waste pit 1 from the waste loading crane 15 is received from the control device 10 and the bag breaking machine 8 is operated. However, the moving route is determined and the moving device 5 is moved to a target position so as not to collide with the deposited garbage. Then, the lifting device 6 is driven to lower the bag breaking machine 8, and the When the landing is detected, the driving of the lifting device 6 is temporarily stopped. The landing of the bag breaking machine 8 can be detected, for example, by measuring the power consumption of the elevating device 6 and detecting the change in power consumption, but can also be detected by other methods.

By controlling the lifting device 6 with an inverter, the bag breaking machine 8 is further lowered at a low speed.
The driving motor 17 of the bag breaking machine 8 is driven to rotate the rotary bag cutting blades 20, 21 in the same direction. As a result, the bag-breaking blades 20, 21 penetrate to a predetermined depth of the refuse thrown into the refuse pit 1 and finely shear so as to tear a flexible garbage bag made of synthetic resin which is difficult to break. You can actively break bags.

At this time, the inclinometer 19 provided in the bag breaking machine 8 is used.
The inclination angle of the bag-breaking machine 8 is measured by the following method. If the inclination angle is equal to or larger than a set value, the descending speed of the bag-breaking machine 8 is reduced or once increased, the bag-breaking blades 20, 21
However, the bag breaking machine 8 is lowered while vertically entering the refuse pit 1 to a predetermined depth.

Further, the power consumption of the driving motor 17 of the bag breaking machine 8 is measured, and when the power consumption becomes equal to or more than the set value, the descent speed of the bag breaking machine 8 is reduced or once increased, the driving is performed. An excessive load is not applied to the driving motor 17 so that a failure of the bag breaking machine 8 due to burning of the driving motor 17 or the like can be prevented.

The depth of entry of the bag-breaking blades 20, 21 into the waste pit 1 into the waste pit 1 is a predetermined value, specifically, the drive shafts 20S, 20 of the bag-breaking blades 20, 21. 21S
Is reached, the lowering of the bag breaking machine 8 and the driving of the drive motor 17 are stopped, and the bag breaking operation at that position is terminated.

Next, the lifting device 6 is driven to raise the bag breaking machine 8, and the completion of the bag breaking operation is transmitted as a completion signal to the trash crane 15 via the control device 10.

Thereafter, the control device 10 interlocks with the refuse input crane 15 and the refuse input gate 14, avoids mutual interference, determines the position (address) for the next bag breaking operation, The waste level information in the waste pit 1 from the crane 15 is received from the control device 10, and the bag breaking machine 8 determines a movement route so as not to collide with the accumulated waste, and moves the movement device 5 to a target position. After moving, the lifting device 6 is driven to lower the bag breaking machine 8. Hereinafter, the same operation is repeated to perform the bag breaking operation over the entire area of the garbage pit 1.

In this manner, the garbage bag is finely sheared and actively ruptured, so that the garbage can be easily agitated and mixed by the bag breaking machine 8 itself or the garbage charging crane 15 or the like. While homogenization can be achieved, the moisture contained in the garbage bag together with the garbage can be drained to reduce the moisture contained in the garbage,
As a result, the bucket 15B of the garbage
The efficiency of the garbage is improved and the mixing and mixing of the garbage is made easier, and the garbage combustion efficiency is increased, enabling continuous and uniform incineration of the garbage. Generation can be suppressed. The water flowing out of the broken garbage bag is discharged from the bottom of the garbage pit 1 and is appropriately processed.

The bag breaking operation by the bag breaking apparatus A is preferably performed at night. This is because, in general, the input of refuse is performed in the daytime, and at this time, refuse reloading is required, and the operation rate of the refuse input crane 15 is high, whereas no refuse is input at night and the refuse input This is because time can be spared, and at this time, a lot of evacuation time of the refuse input crane 15 for the bag breaking operation by the bag breaking device A can be taken. In addition, even if the bag breaking work is performed at night, the automatic operation by the control device 10 improves the working conditions at night, enables operation by a small number of people, and simultaneously operates the incinerator for a long time. It is possible to reduce the amount of harmful substances such as dioxin generated at the time of starting and stopping due to interruption of operation.

And, although not particularly limited,
In the present embodiment, the power is supplied to the girder 3 and the moving device 5 through the curtain cables 11 and 12, and the control signal such as a drive signal between the control device 10 and the control device 10 is supplied. Transmission and reception is also by cable,
It is done by radio.

In this embodiment, the traveling rail 2 on which the girder 3 of the bag breaking device A travels is laid above the waste pit 1 separately from the traveling rail of the waste charging crane 15. However, the traveling rail on which the girder 3 of the bag breaking device A travels and the traveling rail of the refuse charging crane 15 can be shared. Similarly, the girder 3 or the moving device 5 of the bag breaking device A and the crane 15
Gadgets or mobile devices (clubs) can be shared. Furthermore, the bucket 15B of the crane 15 for garbage input
And the bag breaking machine 8 may be alternately mounted, or a spare crane (not shown) installed in the garbage pit 1 may be used, and the bag breaking machine 8 may be mounted instead of the bucket of the spare crane.

As is clear from the above configuration, the bag breaking device for waste pits of the waste disposal plant of the present invention can be incorporated without largely changing the design of the conventional waste incineration plant. Not only the waste pit at the landfill
The present invention can be easily applied to an existing waste disposal site, particularly to a waste pit in a small waste disposal site.

By the way, the bag-breaking machine provided in the bag-breaking device for refuse pits of the refuse disposal plant of the present invention is not limited to the above-mentioned embodiment, and for example, the bag-breaking machine shown in FIGS. Can be used.
