The configuration of the waste treatment system 1 is as shown in FIG. 1, and there is a crushing unit 2 for performing a crushing step and a sorting unit 3 for separating the crushed waste. Further, in the waste treatment system 1 of the present embodiment, there is a conveyor device 40 between the crusher and the magnetic force sorter between the crushing unit 2 and the sorting unit 3, and the waste crushed by the crushing unit 2 is the crusher / magnetic force. It is conveyed to the sorting unit 3 by the inter-sorter conveyor device 40.
The crusher 2 has two crushers 5 and 6. The crusher 5 in the first stage is a device that divides a large amount of waste, and has a rotary blade 8 that rotates at a low speed. Hereinafter, the crusher 5 will be referred to as a first crusher 5.

The sorting unit 3 has a function of separating useful metals iron and aluminum from the waste crushed by the crushing unit 2, separating them into iron, aluminum, and other general waste, and collecting the waste in a predetermined storage place or the like. Have.
The sorting unit 3 includes a magnetic force sorter 12 that separates iron, an aluminum sorter 13 that separates aluminum, and a wind power sorter 15. Further, it has a sieving device 16 for aligning the sizes of wastes and separating excessively large ones. The sieving device 16 is a trommel.

The waste storage location is divided into a general waste carry-out section 20, an iron temporary storage section 21, a general waste temporary storage section 22, and an aluminum temporary storage section 23. A waste storage / discharge device 27 is installed in the general waste carry-out unit 20.
In addition, conveyor devices 30, 31, 32 and hoppers 25, 26 for transporting waste to each device and storage unit are provided.

That is, the waste crushed by the crushing unit 2 is conveyed to the magnetic force sorting machine 12 by the conveyor device 40 between the crusher and the magnetic force sorting machine. Then, iron and other wastes are separated by the magnetic force sorter 12, the iron falls from the iron drop hopper 25 to the lower first iron transfer conveyor 30a, and further passes through the second iron transfer conveyor 30b. Then, it is transported to the iron temporary storage unit 21.

The waste from which irons have been removed by the magnetic force sorter 12 enters the sieving device 16 from the general waste drop hopper 26 and is arranged to a certain size or less. That is, the waste having a certain size or less passes through the sieving device 16 and enters the lower wind power sorting machine 15.
On the other hand, the large waste that remains without passing through the sieving device 16 is returned to the crushing section 2 by a conveyor device (not shown).

After being put into the waste storage / discharge device 27, it is loaded onto the truck 28 and sent to the final treatment facility.
When the general waste transport conveyor 32 is driven in the opposite direction, the waste is transported to the general waste temporary storage unit 22.

In the waste treatment system 1 of the present embodiment, fire extinguishing equipment is arranged in each device. In the waste treatment system 1 of the present embodiment, the fire extinguishing equipment 57, which is particularly characteristic of the conveyor device 40 between the crusher and the magnetic force sorter, is installed. Hereinafter, the configuration of the conveyor device 40 between the crusher and the magnetic force sorter and the fire extinguishing equipment 57 will be described.
The conveyor device 40 between the crusher and the magnetic force sorter throws the waste discharged from the second crusher 6 into the magnetic force sorter 12 installed at a high position, and is installed in an inclined posture.
The conveyor device 40 between the crusher and the magnetic force sorter is a belt conveyor, and the conveyor belt 43 is suspended between the drive pulley 41 and the driven pulley 42 as shown in FIG.

A roller 46 as shown in FIG. 3A or FIG. 3B is installed under the conveyor belt 43, and the conveyor belt 43 has a concave cross-sectional shape.
Further, the conveyor belt 43 is provided with partition-shaped or cross-shaped anti-slip portions 45 at regular intervals. Therefore, the conveyor device 40 between the crusher and the magnetic force sorter is installed in an inclined posture, but as shown in FIG. 4, the waste 60 is caught by the anti-slip portion 45 and does not slip off.
The transport path 48 of the conveyor device 40 between the crusher and the magnetic force sorter is covered with a dome 47 to prevent the waste 60 from scattering.

The fire extinguishing equipment 57 extinguishes a fire by sprinkling water on the combusted material, and has a water supply source (not shown) and a plurality of water discharge nozzles 50. The water discharge nozzle 50 is installed in the dome 47 and is installed in a direction in which water can be discharged vertically toward the transport path 48. However, the water discharged from the water discharge nozzle 50 diffuses at a constant angle.
A plurality of water discharge nozzles 50 are installed, and the water discharge nozzles 50 are divided into a plurality of groups as shown in FIG. 2 to form a plurality of water discharge areas 58.
Since FIG. 2 is a conceptual representation of the embodiment, two water discharge nozzles 50 are arranged in each group, but in reality, the number of water discharge nozzles 50 belonging to each group is other than two (1 or). 3 or more) may be used. Further, the water discharge nozzles 50 may be arranged in one row or a plurality of rows in the width direction of the conveyor device 40 between the crusher and the magnetic force sorter. The number of water discharge nozzles 50 belonging to the nozzle group is not limited, and may be one. In FIG. 4, only one water discharge nozzle 50 in the water discharge area 58 is shown for ease of understanding.

In the present embodiment, a plurality of water discharge nozzles 50 are installed in three groups. That is, the water discharge nozzle 50 is installed separately in the lower nozzle group 51, the middle nozzle group 52, and the high nozzle group 53. As described above, the water discharged from the water discharge nozzle 50 diffuses at a constant angle. Therefore, there are water discharge areas 58a, 58b, and 58c under each nozzle group 51, 52, and 53, respectively. The three water discharge areas 58a, 58b, and 58c are separated by a certain distance and do not overlap. The water discharge areas 58a, 58b, and 58c may overlap.
A fire detection sensor 55 is installed at the base end of the transport path 48. The fire detection sensor 55 detects a flame by temperature or light. The fire detection sensor 55 may detect smoke generation.

Next, the operation of the conveyor device 40 between the crusher and the magnetic force sorter and the fire extinguishing equipment 57 will be described with reference to the flowchart of FIG.
In the conveyor device 40 between the crusher and the magnetic force sorter, the drive pulley 41 is rotated by a motor (not shown), the conveyor belt 43 is run, and the waste 60 discharged from the second crusher 6 is installed at a high position. It is conveyed to the sorter 12.
The transport speed during normal transport is, for example, medium speed or high speed of about 60 m / min.
While the crusher-magnetic force sorter conveyor device 40 is in operation, the fire detection sensor 55 constantly monitors the waste 60 on the transport path 48 for flames (step 1). ..
Then, when the waste 60 starts to burn and a flame is generated, the process proceeds to step 2 and an alarm is issued to notify the worker of the generation of the flame. Subsequently, the process proceeds to step 3, and water discharge is started all at once from the water discharge nozzles 50 of the nozzle groups 51, 52, and 53.

As a modification, a plurality of fire detection sensors 55 may be provided, and water may be started from the water discharge nozzle 50 located near the detected fire detection sensor 55, and may be arranged in the vicinity of the detected fire detection sensor 55 or on the downstream side thereof. Water may be discharged only from the water discharge nozzle 50.
For example, a fire detection sensor 55 corresponding to each of the water discharge areas 58a, 58b, 58c may be provided, and water may be discharged from the water discharge area 58 corresponding to the detected fire detection sensor 55 and the water discharge area 58 on the downstream side thereof.

Then, the process proceeds to step 4 and the timer is started to be timed.
Further, the process proceeds to step 5, and the conveyor device 40 between the crusher and the magnetic force sorter is decelerated. That is, in the present embodiment, even if a flame is generated, the conveyor device 40 between the crusher and the magnetic force sorter is operated without stopping. However, the running speed will be significantly reduced.
Preferably, the speed is reduced to about 1/20 to 1/5 of the normal speed. The most desirable running speed is about 1/15 to 1/8 of the normal time.

The timer setting time is the time when the waste near the detection position of the fire detection sensor 55 finishes passing under all of the nozzle groups 51, 52, and 53 divided into three groups. However, it is not preferable that the waste 60 near the detection position of the fire detection sensor 55 is put into the magnetic force sorter 12 which is the next step. Therefore, during the above time, the waste 60 near the detection position of the fire detection sensor 55 is used. Is the time to pass under all of the nozzle groups 51, 52, 53 divided into three groups and to stop before the end of the transport path 48.
For example, if the fire detection sensor 55 is installed at the base end of the transport path 48 as shown in FIG. 2, the waste 60 that was in the vicinity of the fire detection sensor 55 is the nozzle group 51, 52, 53. It is the time to pass under the lower part in order and reach the front of the high nozzle group 53.

Then, when it is confirmed in step 6 that the timer has expired, the process proceeds to step 7 and the conveyor device 40 between the crusher and the magnetic force sorter is stopped.

Until the crusher-magnetic force sorter conveyor device 40 is stopped in step 7, the crusher-magnetic force sorter conveyor device 40 travels slowly, and the waste 60 on the transport path enters each water discharge area 58. Water is discharged from each water discharge nozzle 50.
For example, the waste 60 that has entered the water discharge area 58b as shown in FIG. 4A receives water from the water discharge nozzle 50 of the central nozzle group 52.
As described above, the conveyor belt 43 is provided with partition-shaped or cross-shaped anti-slip portions 45 at regular intervals. Assuming that, as shown in FIG. 4, the anti-slip portions 45 near the central nozzle group 52 are 45A, 45B, 45C, and 45D. Further, the region sandwiched between the anti-slip portions 45A and 45B is referred to as a region 62ab, the region sandwiched between the anti-slip portions 45B and 45C is referred to as a region 62bc, and the region sandwiched between the anti-slip portions 45C and 45D is referred to as a region 62cd.

At the stage when the water discharge is started, the waste 60 bc held in the area 62 bc between the anti-slip portion 45B and the anti-slip portion 45 C is in the water discharge area 58 b and is splashed with water by the central nozzle group 52. Although the area 62cd adjacent to the water discharge area 58b is within the water discharge area 58b, the anti-slip portion 45C serves as a protective wall to block water, and the waste 60cd is not splashed with water. That is, the region 62cd is hidden behind the anti-slip portion 45C with respect to the central nozzle group 52, and the waste 60cd is not splashed with water.

However, in the present embodiment, the conveyor device 40 between the crusher and the magnetic force sorter is slowly run while discharging water, so that as shown in FIGS. 4 (b), 4 (c), and 4 (d), The relative positional relationship between the anti-slip portion 45B and the water discharge nozzle 50 changes, and in FIG. 4D, water is discharged from the rear of the anti-slip portion 45B. Therefore, in the previous time zone, water is splashed on the area hidden behind the anti-slip portion 45B and the water cannot reach, and the generated flame is extinguished.

Since the alarm is issued in step 2 described above, the operator goes to the vicinity of the conveyor device 40 between the crusher and the magnetic force sorter where the flame is generated to check the state of the flame. When the fire extinguishing is confirmed, the water discharge stop switch (not shown) is operated to stop the water discharge (step 8).
After that, a start switch (not shown) is operated by an operator, and when it is confirmed in step 9, the process proceeds to step 10 and the crusher-magnetic force sorter conveyor device 40 is started.

From the confirmation of the flame generation in step 2 to the start of the conveyor in step 10, it is desirable that some of the peripheral equipment is stopped, part of it is normally operated, and part of it is operated at low speed.
For example, it is desirable to stop the equipment on the upstream side of the equipment in which the flame has occurred so that new waste 60 is not supplied to the equipment in which the fire has occurred.
For example, when a flame is found in the conveyor device 40 between the crusher and the magnetic force sorter, all the equipment belonging to the crusher 2 on the upstream side is stopped.

Further, it is desirable to maintain the drive of the downstream side of the conveyor device 40 between the crusher and the magnetic force sorter in order to prevent waste from stagnation. Since the waste 60 with embers may move to the equipment adjacent to the downstream of the equipment where the flame is generated, it is desirable to operate at a low speed in order to prevent the spread of fire and other types of fire.

Although the above-described embodiment has been described by taking the crusher-magnetic force sorter inter-conveyor device 40 as an example, it is desirable to install the same fire extinguishing equipment 57 in other conveyor devices.
In particular, the crusher-magnetic force sorter inter-conveyor device 40 described in the present embodiment transports the waste immediately after being finely crushed by the second crusher 6, and the frequency of fires due to sparks or the like is high. Since it is expensive, it is recommended to adopt the fire extinguishing equipment 57 of this embodiment.
For the same reason, it is recommended that the fire extinguishing equipment 57 of the present embodiment be adopted for the crusher-to-crusher conveyor 11.

In the above-described embodiment, the belt conveyor is adopted as the conveyor device, but a conveyor having another mechanism may be used. For example, a chain conveyor or a bucket conveyor may be used.

In the above embodiment, after the fire detection sensor 55 detects the flame, the conveyor device 40 is operated for a certain period of time and then stopped. The above-mentioned fixed time is set to a time during which the waste 60 near the detection position of the fire detection sensor 55 finishes passing under all of the nozzle groups 51, 52, and 53 divided into three groups. It is not limited to time. However, it is recommended that the time from the detection of the flame to the stop of the conveyor device is the time for the waste 60 near the detection position of the fire detection sensor 55 to pass through the plurality of water discharge areas 58 and stop. NS.

Further, instead of the method of driving the conveyor device by dividing the time, the mileage of the conveyor device may be obtained by calculation or the like, and the conveyor device may be stopped after traveling for a certain distance.
For example, the rotation speed of the motor that drives the conveyor device may be detected by an encoder or the like, the fire detection sensor 55 may detect the flame, the motor may be rotated by a constant rotation speed, and then the motor may be stopped.

In the embodiment described above, the fire extinguishing equipment 57 that extinguishes the fire by discharging water is adopted, but the one that uses a fire extinguishing gas such as carbon dioxide, the one that uses a powder digestive agent, and the one that uses mist are adopted. You may.

In the embodiment described above, the water discharge nozzles 50 are divided into a plurality of groups and installed, but the layout of the water discharge nozzles 50 is not limited to this configuration, and the water discharge nozzles 50 are arranged in a uniformly dispersed manner. May be adopted.
