2. Description of the Related Art Conventionally, there is known a dust separating / storing device which separates and stores dust and air that have been pneumatically transported in a transport pipe. FIG. 23 is a system diagram of a waste pneumatic transportation plant for explaining such a conventional waste separation and storage device,
FIG. 24 is an explanatory view showing an enlarged main part thereof.

The waste pneumatic transportation plant pneumatically transports the waste discharged from the storage cylinder type waste storage and discharge device 1 and the rotating drum type waste storage and discharge device 11 installed in the building by the transport pipe 6 to collect the waste at the collection center 20. It is supposed to be collected. The storage cylinder type waste storage and discharge device 1 has an upper portion connected to a waste input port 2 of a building, and a waste storage cylinder 3 that temporarily stores the input waste, and a discharge valve 4 provided at the lower end of the waste storage cylinder 3. And a transport branch pipe 5 that connects the discharge valve 4 and the branch pipe 6a on the transport pipe 6 side. A cutoff valve 7 is provided downstream of the discharge valve 4 of the branch pipe 6a, and an intake valve 8 is provided at the most upstream end of the branch pipe 6a. The rotary drum type waste storage and discharge device 11 includes a charging chute 12 whose upper part is connected to a waste charging port 2 of a building.
And has a spiral blade on the inner surface and one end is a charging chute 12
The rotary drum 13 connected to the lower end of the rotary drum 13 and rotated by a drive source (not shown) to convey and discharge the dust once stored to the other end by the pushing action of the spiral blade, and to receive the dust discharged from the rotary drum 13. Discharge chute 14
And the discharge valve 4 provided at the lower end of the discharge chute 14,
It is composed of a transport branch pipe 5 that connects the discharge valve 4 and a branch pipe 6b on the transport pipe 6 side. Further, a cutoff valve 7 is provided downstream of the discharge valve 4 of the branch pipe 6b, and an intake valve 8 is provided at the most upstream end of the branch pipe 6b. In the collection center 20, a separator 21 that is a cyclone dust collector that separates waste from air, a waste discharge device 22 that stores and discharges the waste separated by the separator 21, and a separator 21.
And a bag filter 23 for collecting fine dust that is not separated by a filter cloth or the like.
Inside the transport pipe 6 by sucking the air inside the transport pipe 6 through the separator 21 and the bag filter 23, and the transport device 24 including a screw conveyor that transports the dust collected in step 1 to the dust discharge device 22 side. To the blower 25, a pair of silencers 26 disposed on the suction side and the discharge side of the blower 25 for attenuating the noise generated from the blower 25, and on the downstream side of the silencer 26 on the discharge side. The cooler 27 that is arranged to cool the air heated by the compression of the blower 25, the deodorizer 28 that is arranged on the downstream side of the cooler 27 to remove the odor of dust contained in the air, and the deodorized air An exhaust duct 29 for release to the atmosphere,
A control device 30 that controls the drive system of the blower 25 and the transport device 24 and that controls the opening / closing timing of each discharge valve 4, each shutoff valve 7, and each intake valve 8 is installed.
Then, the waste stored in the waste discharging device 22 is secondarily transported to the waste incinerator 31 by, for example, a container transportation system.

FIG. 24 shows the details of the separator and the waste discharging device. The separator 21 is provided therein with an eliminator 32 so as to block the air discharge passage 21a to the bag filter 23 in the subsequent stage. The eliminator 32 has a large number of cage-shaped fins 32a, and the cage-shaped fins 32a are rotated at a high speed by a driving device (not shown) to function as a filter. The waste discharging device 22 can be roughly classified into three types. One is the container compactor 22A. The container compactor 22A continuously compresses and fills the waste separated by the separator 21 into the container 33 under a vacuum pressure. The container 33 filled with the compressive waste is separated from the container compactor 22A, and the vehicle 34 It is loaded onto the premises and secondarily transported to the incinerator and landfill. The other one is the storage and discharge device 22B. The storage / discharge device 22B is for continuously compressing and storing the dust separated by the separator 21 in a rotating drum 35 having spiral blades on the inner surface thereof under vacuum pressure, and is basically the same as the rotating drum 13 shown in FIG. It has the same configuration as that of. The waste stored in the rotary drum 35 is secondarily transported to an incinerator or a landfill by an existing waste carrier. Still another one is the continuous discharge device 22C. The continuous discharge device 22C continuously discharges the waste separated by the separator 21 directly to the incinerator or the pipeline.

Further, the bag filter 23 in the subsequent stage is provided with a rotary scraping blade (not shown) and a driving device for scraping the dust collected by the filter cloth and accumulated below and discharging it to the conveying device 24. .

[0006] In such a case, the dust that has been pneumatically transported in the transportation pipe 6 is separated from the air in the separator 21 and drops downward. Further, the fine dust collected by the bag filter 23 after passing through the eliminator 32 is conveyed by the transport device 24.
Is carried to the waste discharging device 22 side, and is carried into the waste discharging device 22 together with the waste separated in the separator 21, and is discharged from the discharging device 22, that is, the container compactor 22A, the storage discharging device 22B, or the continuous discharging device 22C. It is transported to the incineration site, etc. via transportation and disposed of. On the other hand, the air separated from the dust in the separator 21 and further separated from the fine dust by the bag filter 23 is the blower 25.
Is sucked by and passes through the blower 25 from the muffler 26 on the suction side, and is compressed from the muffler 26 on the discharge side to the cooler 2.
After being introduced into the deodorizing device 28 via 7 and being deodorized, it is discharged from the exhaust duct 29 to the atmosphere.

[0007] In addition to the above, there is another one disclosed in Japanese Patent Laid-Open No. 145906/55 as a device for pneumatically transporting and separating and storing dust. This publication discloses a storage / discharge rotary drum basically having the same structure as the rotary drum 35 of the storage / discharge device 22B shown in FIG. 24, that is, a base outside the inlet of the rotary drum having spiral blades on its inner surface. The air filter is slidably fixed on the table, and the transportation pipe connected to the dust inlet of the building, etc. is drawn through the air filter into the drum, and the outer surface of the air filter is covered with a small volume air chamber. The air chamber and the blower are connected by an intake pipe.

In this Japanese Patent Laid-Open No. 145906/55, the dust that has been pneumatically transported in the transport pipe is separated from the air in the rotary drum and falls below the discharge port of the transport pipe. The dust that has fallen is pushed forward by the rotation of the spiral blade due to the rotation of the rotary drum, and is pushed out from the rotary drum by the opening of the lid installed on the base outside the discharge port of the rotary drum, and the conveyor below the discharge port. Reprinted on top.

[0009]

However, the dust that has been pneumatically transported in the transport pipe 6 is separated by the separator 21, and fine dust is separated by the eliminator 32 in the separator 21 and the bag filter 23 in the subsequent stage. Collect in stages,
In the former case in which the dust and dust separated from the air in this way are stored in the discharge device 22 and compressed and discharged, the separation of dust, the collection of dust, and the separated air Deodorization from the equipment and storage, compression and discharge of separated and collected dust and dust are carried out by different equipment, so the equipment becomes bulky and the space of the collection center 20 (conventional) Has to grow as large as 700 m ³ ). Further, the eliminator 3 of the separator 21
A motor for driving two, a motor for driving the rotary scraping blades of the bag filter 23, a hydraulic device for the container compactor 22A, a hydraulic device for the continuous discharge device 22C, and a spiral blade for the storage and discharge device 22B are required. Therefore, the equipment cost will be high. Furthermore, the deodorizing device 28 is installed in the blower 2
Since it is arranged on the downstream side (discharging side) of No. 5, in order to prevent the deodorizing efficiency of the deodorizing device 28 from decreasing, the deodorizing device 28
It was necessary to install the cooler 27 in front of, and cool the air that was compressed by the blower 25 and heated. Therefore, if the deodorizing device 28 is arranged on the suction side of the blower 25, the cooler 27 can be omitted. However, in this case, it is necessary to configure the container of the deodorizing device 28 to be a pressure resistant container for the suction capacity of the blower 25. That is, when the deodorizing device 28 is arranged on the discharge side of the blower 25, a relatively inexpensive container that can withstand a pressure of 100 mmH ₂ O is sufficient, whereas the deodorizing device 2
When 8 is placed on the suction side of the blower 25, 6000m
An expensive high pressure container that can withstand a pressure of mH ₂ O (60 times the pressure on the discharge side) is required. Therefore, conventionally, the deodorizing device 28 is disposed on the discharge side of the blower 25, and the air compressed and heated by the blower 25 is cooled by the cooler 27 before the deodorizing device 28. The reality is that we try to prevent it from dropping.

In addition, an air filter is slidably fixedly installed on a base outside the inlet of the storage / drainage rotary drum having a spiral blade on the inner surface, and a transport pipe is passed through the air filter so that the air filter The latter one, in which the outer surface side is connected to the intake pipe on the blower side through the small-volume air chamber, has the following problems. B) The area of the air filter cannot be increased, so it is difficult to increase the suction force of the blower while reducing the air passage speed in the air filter section, and the plant has a large air volume (large dust transport pipe diameter). Not applicable to. B) In order to maintain airtightness between the air filter fixedly installed on the base and the cover of the discharge port and the rotary drum for storage and discharge, which is the rotating body, the structure of the seal part becomes complicated and the device is expensive. Not only that, but the larger the area of the air filter, the larger the size of the seal with a special structure. C) Since the area of the air filter cannot be increased and the volume of the air chamber is small, increasing the suction force of the blower increases the air passage speed in the air filter section, and sucks the transferred dust to the air filter section. Because it causes adhesion
Both the suction pressure of the blower and the air volume must be kept much smaller than in ordinary air transportation. D) For the reason of c) above, the inertial force of the dust that has been pneumatically transported in the transport pipe is small, and the dust that has been pneumatically transported cannot be flown away and compressed, so dust that consists of spiral blades inside the rotating drum. It is necessary to provide a compression device and its drive device, and the device is inevitably complicated and expensive, as well as a waste storage part (rotation drum for storage and discharge).
Since it itself rotates, dust that has dropped once rises up, and it becomes easy to cause suction and adhesion to the air filter portion. E) Since the storage and discharge rotary drum, the inlet air filter, and the discharge port lid are all installed on the base, the waste storage unit (storage and discharge rotary drum including the air filter and lid) itself It is impossible to carry out the container car. F) If the dust transported by air is the dust contained in the bag, it will hit the spiral blades in the rotary drum and be broken, and the above problems d) will occur.

In view of the above points, the present invention makes it possible to integrate and share the facilities in the collection center, compress the space of the collection center, and utilize the inertial force during pneumatic transportation of dust to collect dust. It is an object of the present invention to provide a waste separation storage device that can compress and store waste.

The air pipes connected to the suction side are connected to form a chamber on the transport pipe side as a storage chamber and a chamber on the blower side as an exhaust chamber, and a discharge valve for discharging dust is provided in the storage chamber. It is a thing.

Further, the wind speed in the transportation pipe is set to 13 so that dust that has been pneumatically transported into the storage chamber collides with the innermost wall surface of the storage chamber before it falls to the bottom surface of the storage chamber due to its gravity.

Further, the area of the high-strength filter is set to 2 m / se when the air passage speed in the high-strength filter portion is general dust.
Below c, the area is set to 5 m / sec or less for bag waste and 10 m / sec or less for bottles and cans.

Further, a shut-off valve is provided near the connecting portion of the storage chamber of the transport pipe, and a switching valve for switching the flow path to the blower between the exhaust chamber and the outside air is provided near the connecting portion of the exhaust chamber of the wind pipe. It is provided.

Further, the pressure resistant container can be separated from the transportation pipe and the wind pipe.

[0024]

In the present invention, the dust and dirt that have been pneumatically transported in the transportation pipe are separated from the air in the storage chamber by the high-strength filter that largely divides the pressure vessel into two chambers, and are all stored in the storage chamber. To be done. Then, the dust and the dust stored in the storage chamber are discharged to the outside through the discharge valve.
In this way, by defining the inside of the pressure-resistant container with a high-strength filter, separating all the dust and dust from the air in the storage chamber on the transport pipe side and storing it, the pressure-resistant container section separates dust and dust. Collection, separation and collection and collection of collected dust and dust can be performed, and conventional separators, eliminators, bag filters, discharge devices, etc. can be integrated and shared. Therefore, equipment such as an electric motor for driving the eliminator of the separator and an electric motor for driving the rotary scraping blade of the bag filter are not required, and the equipment cost can be reduced and the space of the collection center can be compressed.

Furthermore, the wind speed in the transportation pipe is set to 13 m / sec to 35 m according to the characteristics of the waste in the area where this device is installed.
/ Sec, the waste transportation speed is 5 m / sec or more for a heavy object having a specific gravity of 0.15 t / m ³ or more, and a specific gravity of 0.15 t / m ³
In the case of the following lightweight products, by setting it to 10 m / sec or more, the dust that has been pneumatically transported into the storage chamber collides with the innermost wall surface of the storage chamber before it falls to the bottom surface of the storage chamber due to its gravity. Therefore, it is possible to compress and store dust sequentially from the innermost portion of the storage chamber by utilizing the inertial force during pneumatic transportation. Therefore, equipment such as a hydraulic device for a container / compactor, a hydraulic device for a continuous discharge device, and a spiral blade for a storage / discharge device is not required, and the cost of the device can be further reduced.

Furthermore, the area of the high-strength filter is set to 2 m when the air passing speed in the high-strength filter portion is general dust.
/ Sec or less, 5 m / sec or less for bag waste and 10 m / sec or less for bottles / cans to reduce the air passage speed in the filter while increasing the suction power of the blower. Therefore, suction and adhesion of fine dust to the filter portion can be suppressed.

Furthermore, by providing a straight pipe portion having a diameter of at least twice the diameter of the transport pipe at the connection portion of the transport pipe with the storage chamber, it is possible to stabilize the entry speed of the dust thrown into the storage chamber,
It is possible to easily adjust the waste transportation speed.

Furthermore, the present apparatus is installed by providing a dust compression degree control means for adjusting the difference in internal pressure between the transportation pipe and the wind pipe to control the compression degree of the dust stored in the storage chamber. It becomes easy to adjust the transportation speed and compression degree according to the characteristics of local waste, and it becomes possible to automate the adjustment of the transportation speed and compression degree of waste.

Further, by providing a dust full detection means for detecting the fullness of the dust in the storage chamber by observing the fluctuation of the internal pressure difference between the transport pipe and the wind pipe, the fullness of the dust can be automatically detected. Thus, it is possible to prevent the blower from being overloaded.

Furthermore, by installing a device for discharging the dust stored in the storage chamber at the bottom of the storage chamber, it is possible to convey the dust compressed and stored in the storage chamber by air transportation to the discharge valve at the time of discharge, and to the outside. The waste can be easily discharged.

Further, by providing a baffle plate having air permeability in the storage chamber, which restricts free flight of pneumatically transported light dust to the high-strength filter side, the high-strength filter side of paper pieces and fine dust is provided. It is possible to restrict free flight to the filter, and it is possible to reliably suppress suction and adhesion of paper chips and fine dust to the filter section.

Furthermore, by installing a deodorizing filter in the middle of the air circulation path in the exhaust chamber, the exhaust chamber, that is, the pressure resistant container, can also serve as the container of the deodorizing device, and the deodorizing filter can be arranged on the suction side of the blower. The container and cooler of the deodorizing device, which have been conventionally required, can be eliminated.

Further, by providing the outside air introduction valve for cleaning the high-strength filter in the exhaust chamber, it becomes possible to introduce the outside air into the exhaust chamber, without stopping the operation of the blower.
The internal pressure of the exhaust chamber can be made higher than the internal pressure of the storage chamber. Therefore, the high-strength filter section can be caused to generate a flow of air from the exhaust chamber to the storage chamber (a flow that is the reverse of that during normal operation), which results in fine dust, etc. adhering to the high-strength filter. Can be blown off and removed, and the high-strength filter can be washed.

Furthermore, a shutoff valve is provided near the connecting portion of the storage chamber of the transport pipe, and a switching valve for switching the flow path to the blower between the exhaust chamber and the outside air is provided near the connecting portion of the exhaust chamber of the wind pipe. By providing the above, the storage chamber and the exhaust chamber can be shut off from the piping system in a vacuum state without stopping the operation of the blower. Then, in this state, by introducing the outside air into the exhaust chamber by the outside air introduction valve, the velocity of the air flowing from the exhaust chamber to the storage chamber can be increased in the high-strength filter portion, and the cleaning effect of the high-strength filter can be enhanced. it can.

Further, by making the pressure-resistant container separable from the transportation pipe and the wind pipe, the pressure-resistant container can have a container function and can be carried out by the vehicle as it is.

【Example】

Example 1. The present invention will be described below with reference to illustrated embodiments.
FIG. 1 is a system diagram of a waste pneumatic transportation plant for explaining a waste separation / storage device according to a first embodiment of the present invention, and FIG. 2 is an enlarged perspective view of an essential part for explaining its operating conditions.
In each of the drawings, parts corresponding to conventional ones are designated by the same reference numerals.

In the refuse separating and storing apparatus of this embodiment, a pressure-resistant container 40 is installed in the collection center 20, and the inside of the pressure-resistant container 40 is divided into upper and lower two chambers by a high-strength filter 41. Connect the transportation pipe 6 connected to the mouth 2 and the air pipe 42 connected to the suction side of the blower 25 to the other side,
The chamber on the side of the transport pipe 6 is formed in the storage chamber 43, the chamber on the side of the blower 25 is formed in the exhaust chamber 44, and the storage chamber 43 is provided with a discharge valve 45 for discharging dust.

In the waste separation / storage apparatus of this embodiment, the shape of the pressure container 40 is not particularly limited, and may be, for example, a cone or a polygonal cross section. You can also use the floor). In short, any shape can be adopted as long as the required pressure resistance can be obtained and the area of the high-strength filter 41 that defines the interior into two chambers can be increased. Further, the material of the high-strength filter 41 is not particularly limited, and any material such as a plastic filter and punching metal can be adopted as long as the required strength is obtained and the air permeability is good. . Therefore, if a plastic filter, punching metal, or the like, whose strength is relatively easy to secure, is used as the base, a wire mesh, tetron felt, or the like may be combined therewith to form the filter. Furthermore, the mounting position of the peripheral portion of the high-strength filter 41 is set to the pressure resistant container 40.
It may be provided on any of the upper surface, side surface, and bottom surface inside.

The control device 4 is installed in the collection center 20.
6 is installed. The control device 46 controls the blower 25 under the operating conditions described later, and also controls the opening / closing timing of each discharge valve 4, each cutoff valve 7, and each intake valve 8 on the building side.

In the waste separation / storage device of the present embodiment having the above-mentioned structure, the dust and the dust that has been pneumatically transported through the transport pipe 6 has a high-strength filter in which the pressure vessel 40 is largely divided into two chambers. It is separated from the air in the storage chamber 43 by 41, and is entirely stored in the storage chamber 43. Then, the dust and the dust stored in the storage chamber 43 are discharged to the outside through the discharge valve 45. As described above, in the waste separation / storage device of the present embodiment, the inside of the pressure-resistant container 40 is defined by the high-strength filter 41, and all the dust and dust are separated from the air in the storage chamber 43 on the side of the transport pipe 6 and stored. After that, since it is designed to be discharged to the outside, the conventional separator, eliminator, bag filter, and dust removal that are the functions of the discharge device, the collection of dust, the storage of separated / collected dust and dust, The single pressure-resistant container 40 part can have all the functions of discharging. For this reason, equipment such as an electric motor for driving the eliminator of the separator and an electric motor for driving the rotary scraping blade of the bag filter are not required, and the equipment cost can be reduced and the space of the collecting center 20 can be reduced to half that of the conventional one. Can be compressed up to. That is, it is possible to compress the space of the collection center 20 which was required to be 700 m ^{3 in the} past to 350 m ³ .

In addition, in the waste separation / storage device of this embodiment, the operating conditions were set as follows. That is, the transport pipe 6
The internal wind speed is 13 m / sec to 35 m / sec, and the dust transport speed is 5 m / in the case of heavy objects with a specific gravity of 0.15 t / m ³ or more.
It is set to 10 m / sec or more in the case of a lightweight object having a specific gravity of 0.15 t / m ³ or less (for example, paper, cloth, vinyl, etc.). This operating condition was set in advance by taking into consideration the characteristics of the dust (waste weight) generated in the area where this device is installed. Here, the reason why the lower limit value of the wind speed is set to 13 m / sec is to ensure stable pneumatic transportation even for lightweight dust. Also, the upper limit of wind speed is 35 m / sec.
The reason for doing so is to enable air transportation even in kitchen waste. The upper limit value of the wind speed of 35 m / sec is, in other words, the lower limit value for enabling the air transportation of garbage. The reason why the upper limit value of wind speed of 35 m / sec is kept low is that when the wind speed rises, the pressure loss increases with the square of the wind speed, and therefore the power (blower) must be increased. This is because the disadvantages increase as the wind speed increases. As a result, the dust that has been pneumatically transported into the storage chamber 43 is stored in the storage chamber 43 due to its gravity.
Before falling to the bottom, it can be collided with the innermost wall surface of the storage chamber 43, and the inertial force during pneumatic transportation can be used to sequentially compress and store dust from the innermost portion of the storage chamber 43. It was Therefore, the conventional equipment such as a hydraulic device for a container / compactor, a hydraulic device for a continuous discharge device, and a spiral blade for a storage / discharge device is not required, and the cost of the device can be further reduced. Further, when the dust to be transported by air is the dust contained in the bag, the apparatus of the present embodiment uses the inertial force at the time of transporting the air to compress and store the dust, so that the bag is prevented from being damaged. For this reason, the dust that has dropped once does not rise, and it is possible to suppress the suction adhesion of the lightweight dust to the filter portion.

In the waste separation / storage device of this embodiment, the area of the high-strength filter 41 is set as follows. That is, the air passage speed in the filter part is 2 m / sec or less for general waste and 5 m / sec or less for bag waste,
In the case of bottles and cans, the area was set to 10 m / sec or less. As a result, the air passing speed in the filter portion can be reduced while increasing the suction force of the blower 25, and the suction and adhesion of fine dust to the filter portion can be suppressed.

The above operating conditions and filter area will be described with reference to FIG. As shown in the figure, the pressure-resistant container 40 is made of a rectangular parallelepiped box, the high-strength filter 41 has a longitudinal dimension of 2 m and a lateral dimension of 4 m, and the transport pipe 6 is a pipe of 400 A (diameter of about 400 mm).
When collecting general waste, the wind speed in the transport pipe 6 should be 20m.
/ Sec, the air volume Q is Q = 0.4 × 0.4 × π ÷ 4 × 20 = 2.5 m ³ / sec The filter area A is A = 4 × 2 = 8 m ² Therefore, the air passage velocity V in the filter section Becomes V = Q ÷ A = 2.5 ÷ 8 = 0.3m / sec, which is within the range of 0.3m / sec <2m / sec.

By the way, in the conventional container compactor, the dust is put into the container (10 m ³ ) under hydraulic pressure (about 25 tons).
), And in the case of general garbage, 1 / in the container
It is compressed and stored at 2.5. The apparatus of this embodiment performs this compression storage by using the suction force of the blower 25. This will be described with specific numerical values. Set the suction pressure of the blower 25 (or the differential pressure between the storage chamber and the exhaust chamber) to -0.3 kg / cm ^2.
Let G be the load P generated in the filter section in FIG.
Is P = 400 cm × 200 cm × 0.3 kg / cm ² = 24000 kg = 24 tons. That is, by increasing the strength of the filter, it is possible to apply a load of 24 tons to the dust in the storage chamber 43 and push it in only with the suction force of the blower 25.

Further, in the waste separation / storage apparatus of this embodiment, the connecting portion of the transport pipe 6 with the storage chamber 43 has a length L (diameter 400 m or more) which is more than twice the diameter of the transport pipe 6, as shown in FIG.
In the case of the m pipe, L is set to 800 mm or more) and is constituted by the straight pipe portion 6A. This stabilizes the entry speed of the dust thrown into the storage chamber 43 and facilitates the adjustment of the dust transport speed.

Example 2. FIG. 4 is a cross-sectional view schematically showing the configuration of the main parts of the waste separation / storage device according to the second embodiment of the present invention. In the figure, the parts corresponding to the above-mentioned first embodiment are designated by the same reference numerals. I am doing it.

In the waste separation / storage device of this embodiment, the pressure resistant container 40 is divided into two chambers by a high-strength filter 41 into left and right chambers, and a transportation pipe 6 connected to the dust inlet of the building is provided in the left chamber. 41 is penetrated and connected, and a right side chamber is connected with a wind pipe 42 connected to the suction side of the blower,
The left chamber is formed in the storage chamber 43, and the right chamber is formed in the exhaust chamber 44. The other configurations are the same as those in the first embodiment.

In this embodiment, the depth of the pressure vessel 40 in the direction orthogonal to the drawing is set wide enough to secure the area required by the high-strength filter 41. This allows
The height dimension of the pressure resistant container 40 can be compressed, and the space of the collection center 20 can be compressed in the height direction.
