2. Description of the Related Art Conventionally, there is a technology disclosed in Japanese Patent Laid-Open No. 1-285510 as a garbage collection equipment using pneumatic transport. This technology is applied to central cleaner piping.
A shredder that shreds documents into shredded garbage,
The floor dust suction cleaner is connected with a branch pipe, and the shredded dust and floor dust are pneumatically transported through the central cleaner piping by the suction force of the suction device, and collected in the central cleaner. The cleaner comprises a hose with an attachment;
The hose is inserted into an inlet valve attached to the branch pipe and fixed with the attachment.

[Problem to be Solved by the Invention] In garbage collection equipment using pneumatic transportation, the cleaner that sucks floor garbage must be given a fairly strong suction force, so the air volume (the amount of air flowing in the transportation pipe) is small. , and degree of vacuum (
It is necessary to transport the waste in a pipe with a high level of suction (related to the suction power for dirt). On the other hand, since the shredded waste from the shredder is lightweight and has a small bulk specific gravity, it is preferable to transport it in a pipe with a large air volume and a low degree of vacuum. When transporting shredded waste, when air flows through branch pipes and transport pipes, if the air volume and vacuum level are not suitable for the transport, for example, the air volume may exceed the limits and the vacuum level may be high. When this happens, the air that encounters resistance at bends, etc. rotates, creating a pulsating flow (a phenomenon in which air swirls and stagnates).
It is characterized by the fact that it tends to occur. As mentioned above, the shredded trash is lightweight and has a small bulk specific gravity, so when it moves normally on air, it maintains a so-called mixed state with air between each piece of shredded trash, but the pulsating flow When this happens, the pieces of shredded garbage tend to stick together and become solid. When this solidified state of shredded waste occurs, the air resistance inside the pipe changes, and this state is accelerated in that part, and a similar state occurs in other parts. As this condition progresses, the shredded debris causes obstruction in the pipe. Similarly, when transporting shredded trash, if the air volume exceeds the limit and the vacuum level is high, a large amount of shredded trash may pass through the bends at once, and they may not be able to pass through the bends and become clogged. Intraductal obstruction may occur due to debris. Once these intra-pipe occlusion problems occur, it is not only difficult to restore the original normal state even if the air volume and vacuum level within the pipes are adjusted, but also, in particularly severe cases, it is necessary to clean the pipes. As described above, in this type of garbage collection equipment, it is necessary to adjust the air volume and degree of vacuum within the transportation pipe depending on the type of garbage to be transported.

However, in the conventional example described above, the air volume and degree of vacuum suitable for each of the shredded garbage and the floor garbage are not configured to be applied to the transport pipe and the branch pipe each time, so it is not possible to transport the floor garbage. If the air volume and degree of vacuum are set in such a manner, the above-mentioned obstruction in the pipe due to shredded debris is likely to occur. Furthermore, since the conventional shredder adopts a discharge method in which shredded waste is simply thrown into a branch pipe, the branch pipe into which a large amount of shredded waste is fed at once becomes clogged, resulting in pipe blockage. There is also the problem of causing

[0005] It is an object of the present invention to solve each of the above-mentioned problems, and an object of the present invention is to provide garbage collection equipment using pneumatic transport that solves the problems.

[0006]

[Means for Solving the Problems] The applicant has proposed that the amount of air sucked from the air suction portion 1a of the transport pipe 1 can be adjusted by adjusting the air volume and degree of vacuum in the transport pipe 1 of this type of pneumatic transport garbage collection equipment. Attention was paid to the fact that this is achieved by raising and lowering the internal pressure of the transport pipe 1. The present invention utilizes this point to achieve the above object, and as a first solution,
For example, first, there are six shredders 3a and 3b placed in various parts of the building that shred documents, etc. into shredded garbage.
, 3c, 3d, 3e, 3f, and a plurality of inlet valves 6, which are also arranged at various places in the building, to which a cleaner for sucking floor dust is connected, and an air suction section 1a at one end, and an air suction section 1a at the other end. is located at a predetermined portion of the building, and at an intermediate location, each of the shredders 3a, 3b, 3c, 3
d, 3e, 3f and branch pipes 7... connected to the inlet valves 6..., a transport pipe 1, provided at the other end of the transport pipe 1, a cyclone 21 serving as a dust collector, a bag filter 22, and In a pneumatic garbage collection facility equipped with a central cleaner 2 having a suction blower 23 as a suction device, a detection mechanism consisting of a Venturi tube 41, a pressure guide tube 43, and a diaphragm 44 for detecting the internal pressure of the transportation pipe 1; A valve body 42 is displaceable to expand or contract the inner diameter of the transport pipe 1, and the valve body 42 is configured to maintain the internal pressure of the transport pipe 1 at a set pressure value set according to the type of garbage or the position of the shredder. An automatic pressure regulator 4 comprising a valve body drive section 45 capable of controlling the opening/closing operation of the air intake section 1a is attached to the transport pipe 1 near the air suction section 1a.

As a second solution, for example, each of the shredders 3a, 3b, 3c, 3d, 3e, and 3f is provided with a discharge mechanism configured to discharge the shredded garbage from the garbage container 33 little by little. In addition, there is a connecting pipe 37 connected to the discharge site of the garbage container 33, a secondary air supply section 36b that allows air to flow in the direction in which the shredded garbage moves, and a branch pipe 7 located at a location within the building. A multiphase chamber is provided, which is comprised of a secondary air control valve 36a that can adjust the air volume according to the piping condition and the amount of shredded garbage.

As a third solution, for example, each branch pipe 7 to which the shredders 3a, 3b, 3c, 3d, 3e, 3f are connected is provided with an air merging pipe 5 connected to the air suction part 1a. , flash air pipes 51a, 52a, 53a, 54a connected to the air merging pipe 5, and flash valves 51, 52, for opening and closing each of the flash air pipes.
A flash mechanism consisting of 53 and 54 is attached.

[0009]

[Operation] According to the first solution, since the automatic pressure regulator 4 can control the air volume and degree of vacuum in the transport pipe 1 according to the type of garbage, etc., the transport pipe 1 or the branch pipe 7
It is possible to prevent the above-mentioned occlusion failure in the pipe, and also to enable smooth garbage transport.

According to the second solution, each of the shredders 3a, 3b, 3c, 3d, 3e, and 3f has a discharge mechanism capable of discharging shredded garbage little by little, and a discharge mechanism capable of discharging shredded garbage little by little. Since a mixed phase chamber is provided that can supply secondary air to the shredded trash, the shredded trash can be reliably delivered to each of the shredders 3a, 3 without clogging.
b, 3c, 3d, 3e, 3f can pass through branch pipes 7...

According to the third solution, the flush mechanism can forcibly move the shredded trash to the transport pipe 1 in order to prevent the shredded trash from accumulating in the branch pipes 7. The newly discharged shredded trash is added to the shredded trash discharged and the shredded trash discharged from other shredders and remains, and the amount of shredded trash inside the branch pipe 7 increases. This can prevent intraductal occlusion problems. In addition,
Since the movement from the branch pipes 7 to between the transport pipes 1 can be performed quickly, the transport time can be shortened. If this type of garbage collection equipment does not use this flushing mechanism, it would take a considerable amount of time to move the shredded garbage remaining in the branch pipes 7 to the transport pipe 1. .

(the part where branch pipe 7... branches from transport pipe 1)
, each shredder 3a, 3b, 3c, 3d, 3e, 3f
The radius of curvature of the bent portions of the nearby branch pipes 7 is made large so that shredded waste and floor waste can easily stagnate and block the insides of these pipes, so that they can pass smoothly. However, if the radius of curvature of the transport pipe 1 and the branch pipes 7 is too large, it may not be possible to arrange them under the floor or in the wall of a building. The transport pipe 1 and the branch pipe 7 in this embodiment.
In view of the above points, each radius of curvature is determined based on each formula listed in Table 1.

[Table 1] By the way, as can be understood from Table 1, the radius of curvature R1 of transport pipe 1 and branch pipe 7 for shredded waste is larger than that for floor waste, so shredded waste and floor In the case of a curved portion of the transport pipe 1 or the branch pipe 7 through which garbage passes, the radius of curvature must be R1 for shredded garbage. It should be noted that there is no problem even if the radius of curvature R1 of the one for shredded garbage is larger than the radius of curvature R2 of the one for floor garbage.

As shown in FIG. 1, the central cleaner 2 includes a cyclone 21, which is a dust collector for shredded waste, connected to the other end of the transport pipe 1 by a cyclone connecting pipe 21b equipped with a switching valve 21a, and Switching valve 2 on the other end
The bag filter 22 is a dust collector for floor dust connected by a bag filter connecting pipe 22b provided with a bag filter 2a, and the suction blower 23 is the suction device connected to the bag filter 22. An inverter control device is attached to the motor (not shown) of the suction blower 23, and is configured to adjust the output of the suction blower 23 in accordance with the transportation of shredded garbage and floor garbage. Furthermore, a shredded trash storage container 24 is provided below the cyclone 21 to accommodate the collected shredded trash. The shredded trash is configured so that it can be sent from the shredded trash storage container 24 to a trash transport vehicle 26 via a discharge gate 25 by driving a screw feeder (not shown). Further, below the bag filter 22, a floor dust storage device 27 is provided for storing floor dust. By the way, shredded waste can be used as water-soluble recycled paper such as toilet paper, but for this purpose it is important to separate and collect the shredded waste. From this point of view, the pneumatic transport garbage collection equipment is configured so that the shredded garbage can be easily separated and sent to the transport vehicle 26.
It can contribute to the reuse of resources. Note that the reference numeral 28 in FIG. 1 is a deodorizer for deodorizing exhaust air.

As clearly shown in FIG. 3, the shredder 3b has a cutter 31 provided at the top of the main body, a cutter 31 disposed inside the main body, the top of which is open, and a discharge port 32a located off-center. A garbage container 33 having a bottom portion 32; and an arm-shaped discharge member 35 that is located at the center of the bottom portion 32, is fixed to a rotating shaft 35a connected to a motor 34 by a connecting belt 34a, and is rotatable along the surface of the bottom portion 32. and a mixed-phase chamber in which shredded garbage together with the primary air can flow into the connecting pipe 37 from the discharge port 32a, and secondary air can flow into the connecting pipe 37 from the secondary air suction part provided with the filter 36b. , sensors 38, 38 are attached to the upper part of the trash container 33 to detect when the shredded trash is full. When the sensors 38, 38 detect that the shredded garbage is full, the cutter 31
The controller is configured to output a full signal to the central controller (not shown) in order to stop the controller. The multiphase chamber includes the secondary air suction section, the connecting pipe 37, and the connecting pipe 37.
It is constituted by a vertical joint 37a attached to the pipe for vertically connecting the ends of the branch pipes 7, and a horizontal joint 37b for connecting the branch pipes 7 in the horizontal direction. Further, the dust discharge mechanism is constituted by the dust discharge port 32a and the discharge member 35. The discharge port 32a is configured to have a size that allows the shredded garbage to be discharged little by little and reliably. Note that the secondary air intake section is provided with a secondary air control valve 36a that can be manually adjusted. In addition, in this shredder 3b, a branch pipe 7 end is connected to the joint 37a, and a cutoff valve 7b provided at the branch pipe 7 end is closed when shredded waste is not being transported. As shown in FIG. 1, other shredders 3a, 3c, 3d, 3e,
The branch pipe 7 corresponding to 3f has the shredder 3
As in case b, the cutoff valves 7a, 7c, 7d,
7e and 7f, and among the other shredders 3a, 3c, 3d, 3e, and 3f, the shredders 3d, 3e, and 3f have a branch pipe 7 in the vertical joint 37a, similar to the shredder 3b. The shredders 3a and 3c each have a branch pipe 7 connected at its end to the horizontal joint 37b. Two joints 3 with different directions like this
7a and 37b are provided in each shredder 3.
This is to enable selection of the one that is easier to install depending on the installation location of each of a, 3b, 3c, 3d, 3e, and 3f. In FIG. 3, reference numeral 39 is an operation panel for operating the shredder 3a to drive and stop the shredder 3a.

As shown in FIG. 1, each of the shredders 3
a, 3b, 3c, 3d, 3e, 3f are shredders 3
The shredders a and 3c are divided into a first group, the shredders 3b and 3d are divided into a second group, and the shredders 3e and 3f are divided into a third group. The shredder 3 belonging to the same group
Shredders a and 3c, shredders 3b and 3d, and shredders 3e and 3f are arranged at similar distances from the suction blower 23, respectively. When the trash container 33 of one of the shredders in each group, for example, the shredder 3b belonging to the second group, becomes full and a full signal is output from the sensors 38, 38 to the central control device, the shredders 3b, 3d Motor 3 in
4 and an instruction signal for opening the shutoff valves 7b and 7d are output from the central control device. Further, the automatic pressure adjustment device 4
Now, shredder 3 which also belongs to the second group
Pressure settings corresponding to the transport of shredded garbage from ports b and 3d are made, and in the central cleaner 2, the switching valve 21a is opened and the switching valve 22a is opened according to an instruction signal from the central control device.
Blocking operation, cyclone 21 drive and bag filter 22
Stopping, etc. will be carried out. The reason why each shredder is divided in this way is that it is possible to transport shredded garbage in groups.
This is because the transportation time can be shortened compared to the case where each shredder is transported separately. It goes without saying that when configuring each group, the number of shredders is determined so that the amount of shredded garbage is such that it does not cause any trouble to the transportation.

The automatic pressure regulating device 4 is configured such that when the width of the air passage surface in the transport pipe 1 for air transport is reduced, the internal pressure of the transport pipe 1 increases, the air volume within the transport pipe 1 decreases, and Utilizing the characteristics of a transport pipe with a suction device, when the degree of vacuum increases and, conversely, the air passage surface of the transport pipe 1 is expanded and the internal pressure decreases, the air volume increases and the vacuum level decreases. It controls the degree of vacuum. The automatic pressure regulating device 4 is, as shown in FIG. 1, provided in the transport pipe 1 near the air suction portion 1a, and as shown in FIG. , a valve body 42 provided in the transport pipe 1 and displaced to expand or contract the air passage surface in the transport pipe 1, a pump (not shown) that operates to displace the valve body 42, and the Venturi pipe. 41 A diaphragm 44 connected to the other end of the pressure guide tube 43 whose one end is connected to the venturi tube 41 so that the internal pressure is transmitted;
The pump is configured to detect the internal pressure at a displacement amount of 4, and operate the pump to displace the valve body 42 so that the internal pressure of the transport pipe 1 is set by an instruction signal from an electrically connected central control device. It consists of a valve body drive section 45. In addition,
The venturi tube 41, pressure guide tube 43, and diaphragm 44 constitute a pressure detection mechanism. Then, the central control device outputs an instruction signal to the valve body drive unit 45 of the automatic pressure regulator 4 to the effect that the internal pressure of the transport pipe 1 should be set in accordance with the air volume and degree of vacuum suitable for transporting the garbage.

By the way, when transporting trash in a trash collection facility using pneumatic transportation, it is important to provide suitable air volume and degree of vacuum in the transport pipe 1 and branch pipes 7 depending on the type of trash so that the trash can be transported smoothly. Necessary for transportation. Furthermore, since the first, second, and third groups are farther from the suction blower 23 than the first group, and the third group is farther than the second group, the air in the transport pipe 1 is If the width of the passage surface is the same, the air volume and degree of vacuum applied to the shredded waste discharged from each group will be different, so the air volume and degree of vacuum applied to the shredded waste from each group will be different. It is necessary to provide a degree of vacuum. In this embodiment, in order to control the air volume and degree of vacuum, as described above, the width of the air passage surface in the transport pipe 1 is changed each time, and the size of the air passage surface corresponding to each shredder is changed as described above. In each branch pipe 7..., the secondary air control valve 36a of the multiphase chamber is initially adjusted manually.

As shown in FIG. 1, the shredder 3a
, 3b, 3c, 3d, 3e, 3f are connected to the branch pipes 7..., which are flush air pipes 51a, 52a, 53a, which are connected to the air suction part 1a via the air merging pipe 5.
54a, and a flush mechanism consisting of flush valves 51, 52, 53, and 54 that can open and close the inside of each of the flush air pipes is connected. This flush mechanism allows the shredded waste remaining in the branch pipes 7 to be quickly moved to the transport pipe 1.

Note that the valve body 42 of the automatic pressure regulator 4
, cutoff valves 7a, 7b, 7c, 7d, 7e of branch pipes 7...
, 7f, the flush valves 51, 52, 53, 54, the switching valve 21a, and the switching valve 22a are each provided with a motor (not shown) that is electrically connected to the central control device. Each of the motors is driven by various instruction signals from the motor and opens and closes.

By the way, compared to shredded garbage, floor garbage does not discharge a large amount of garbage into the transport pipe 1 and branch pipes 7 at one time, and has a large bulk specific gravity, so it is not caused by pulsating flow. Since pipe clogging is less likely to occur, each cleaner is divided into groups and transported separately, as in the case of shredded waste, each cleaner is provided with the mixed phase chamber, and a flush mechanism is also attached. There's no need.

Next, the operation of the garbage collection equipment according to the above embodiment will be described with reference to FIG. 4, which is an explanatory diagram of the operation of each member in the entire garbage collection equipment by pneumatic transportation, and an illustration diagram illustrating the operation of each mechanism and each member in transporting shredded garbage. This will be explained based on FIG. Note that FIG. 5 shows a portion of the total working time.

As shown in FIG. 4, the cleaner (not shown) is used during the morning and evening hours (8:00 to 10:00).
00 and 17:00 to 19:00), and during this period, the cleaner is attached to the inlet valve 6 . When the time period comes, the valve body drive unit 45 of the automatic pressure regulator 4 is activated in response to an instruction signal from the central controller (not shown), so as to generate the suitable air volume and degree of vacuum for transporting floor waste. The valve body 42 is used to set the pressure inside the transport pipe 1.
is displaced. The time period can be arbitrarily set using a timer or the like. On the other hand, in the central cleaner 2, the suction blower 23 is driven, the switching valve 21a is closed, and the switching valve 22a is opened. Then, the floor dust sucked by each cleaner is pneumatically transported through the transport pipe 1 through the inlet valves 6, branch pipes 7, etc., and enters the bag filter connecting pipe 22b of the central cleaner 2, and enters the switching valve 22a. and enters the bag filter 22. Inside the bag filter 22, floor dust and air are separated, and the floor dust is discharged to the floor dust storage device 27, and the air is exhausted to the outside via the suction blower 23 and the deodorizer 28.

:00~17:00) are shredders 3a, 3b, 3
The shredded garbage discharged from c, 3d, 3e, and 3f is transported, but in order to protect the suction blower 23 during this time period, after continuous operation for a certain period of time, there is a downtime S0...・It is designed to provide. The pause time S0
After continuous operation for more than a certain period of time, the suction blower 23 is stopped while transportation of shredded garbage from one group of the shredders is completed and a full signal from another group is received. However, each pause time S0...
- If a full signal is output to the central control unit from a shredder in another group during the process, transport of shredded garbage for that group will not be started immediately, and the suction blower 23 and each member, etc. It is controlled so that it is kept on standby. In addition, when one group receives a full signal from another group while transporting shredded waste,
The suction blower 23 continues to operate, but since such a situation does not occur frequently, the suction blower 23 can take the above-mentioned pause time S0 as appropriate. Further, if the full signal is not outputted from any shredder after the end of the downtime S0, the suction blower 23 continues to be in the resting state, and the downtime duration S0 is changed to the downtime S0.
It will stop for a period of time equal to 1 (see Figures 4 and 5).

To explain in more detail the operation of the garbage collection equipment including the operation of the suction blower 23 mentioned above, as shown in FIG.
When the shredder 3a, which is one of the shredders 3b, 3c, 3d, 3e, and 3f, becomes full and the full signal is output, the shutoff valves 7a and 7c of the shredders 3a and 3c belonging to the first group are opened. , shredder 3a, 3c
The discharge member 35 is activated. By the operation of this discharge member 35, the shredded garbage in each garbage container 33 of the shredders 3a, 3c is removed by a predetermined amount from the discharge port 32a together with primary air.
The secondary air flowing from the secondary air suction section 36 increases the air volume and smoothly flows through the branch pipes 7 and 7.
Move to transport pipe 1. Subsequently, when the shredded waste has almost finished moving from the branch pipe 7 to the transport pipe 1, the discharge member 35 stops, and the shutoff valves 7a, 7c corresponding to the respective shredders 3a, 3c are closed. Subsequently, the flush valves 51 and 52 of the flush mechanism are opened, and air flows from the air suction part 1a through the filter 8, through the flash air pipes 51a and 52a, and the branch pipes 7, 7, to the transport pipe 1, and then to the branch pipe 7.
, 7 to reliably move the shredded waste remaining in the transport pipe 1. Note that when the flush mechanism operates, the automatic pressure regulator 4 operates to maintain the set pressure by adjusting the valve body 4.
2 to narrow the air passage surface. When this flush mechanism is used, the air volume in the branch pipes 7... is temporarily increased, and the remaining shredded garbage is quickly removed from the branch pipes 7...
This has the advantage that transportation time can be shortened.

After the shredded waste is thus transported to the central cleaner 2 via the branch pipes 7, 7 and the transport pipe 1, the suction blower 23 stops for a rest period S0. Further, after the end of this downtime S0, if no full signal is output from any shredder belonging to any group, the suction blower 23 continues to be stopped for a further downtime duration S1. After the pause time S0 and the pause duration S1, as shown in FIG. 5, when the full signal is output from the shredders 3d of the second group, the shredders 3b and the shredders 3b are ejected from the shredders 3b in the same manner as in the first group. transport the shredded waste. Next, when the full signal is output from the shredder 3e of the third group during the down time S0 of the suction blower 23, the shredder 3e is shredded together with the shredder 3f after the down time S0 ends as shown by the arrow. Transport garbage. Further, if the full signal is output to the shredders 3c of the second group during the transportation work of the third group, the shredders 3c
The shredded garbage from the shredder 3c is transported together with the shredder 3c. Although not shown, when a plurality of full signals are output during work or during the downtime S0, the transportation work is continued in the order in which the full signals were output after the work of the other group. Incidentally, since such a situation in which each group continuously discharges shredded garbage does not occur frequently, the suction blower 23 will appropriately take the above-mentioned pause time S0. The output of these various full signals is controlled as described above by the control of the central controller. Then, the shredded garbage sent into the transport pipe 1 enters the cyclone connecting pipe 21b of the central cleaner 2, passes through the switching valve 21a, and passes through the cyclone 2.
Enter 1. Shredded trash and air are separated in the cyclone 21, and the shredded trash is discharged to the shredded trash storage container 24, and the air is exhausted to the outside through a bag filter 22, a suction blower 23, and a deodorizer 28. The shredded trash collected in the shredded trash storage container 24 is loaded onto a trash truck 26 via a discharge gate 25 by a screw feeder in the shredded trash storage container 24, and transported outside the building.

The garbage collection equipment according to the above embodiment transports the floor garbage and the shredded garbage separately, so that the shredded garbage can be collected separately, contributing to the recycling of garbage. Also,
Since the automatic pressure regulating device 4 is attached, the air volume and degree of vacuum can be set and maintained in accordance with the type of garbage or the shredder position for each group, so that garbage can be transported smoothly. In particular, when transporting shredded waste, the air volume and degree of vacuum can be controlled to maintain them within suitable numerical ranges, thereby preventing obstructions in the pipes. Furthermore, each shredder is equipped with a discharge mechanism that discharges shredded waste little by little, and a mixed-phase chamber that allows secondary air to flow in, so a large amount of shredded waste is removed from the branch pipe 7.
. . , thereby preventing the branch pipe 7 from being clogged. In addition, since the flush mechanism is provided, the shredded garbage in the branch pipes 7 can be forcibly and quickly transported to the central cleaner 2, so that the problem of blockage in the branch pipes 7 can be prevented. Therefore, transportation work can be speeded up.

The present invention is not limited to the above-mentioned embodiments; for example, the entire equipment may be made larger than that of the embodiments, the number of shredders may be increased, and the number of shredders belonging to one group may be three or more. You can also do this. Furthermore, the pressure detection mechanism of the automatic pressure regulator 4, the discharge mechanism of each shredder, and the mixed phase chamber may be changed to systems different from those of the above embodiments. In addition, in the embodiment, the flash tubes 51a, 52a, 53a, 5
4a is connected to the air suction part 1a of the transport pipe 1 via the air merging pipe 5, but the air merging pipe 5 may be connected to another air suction part provided separately, or the flash pipes 51a, 5

[Effect] Since the present invention is constructed as described above, the air volume and degree of vacuum can be set and maintained according to the type of garbage or the shredder position using the automatic pressure regulating device, so that smooth garbage transportation is possible. . In particular, when transporting shredded waste, the air volume and degree of vacuum can be controlled to maintain them within suitable numerical ranges, thereby preventing obstructions in the pipes.

[0031] Since the shredder is provided with a discharge mechanism and a mixed phase chamber into which secondary air can flow, the shredded waste is discharged little by little and reliably passes through the branch pipe. Therefore, it is possible to prevent intraductal occlusion failure of the branch pipe.

[0032] Since the flush mechanism is provided, the shredded garbage in the branch pipes can be forcibly and quickly transported to the central cleaner, which not only prevents blockage in the branch pipes but also speeds up the transport work. can be achieved.
