Description

DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION "Field of Industrial Application" The present invention relates to pneumatic transport of waste and its apparatus.

"Prior Art and Problems to be Solved by the Invention" FIG. 1 is a perspective view showing a conventional pneumatic transport method for waste. 1 is a garbage input port 2 installed in the building
The dust chute 1 is connected directly or via a storage discharger 4 to a discharge valve 3, and the discharge valve 3 is connected to a transport pipe 5, and the transport pipes 5 are collected in each region and centrally connected. The air is sent to the separator 7 of the processing device 6, where it is separated from the dust.The dust is discharged through the center storage and discharge machine 8, and the air is sent to the air pipe 9 and the dust collector 1, such as a bag filter.
0, the dust is removed, and the air is sucked by the blower 11.

In the above-described pneumatic transportation method, the transportation piping 5 has the same cross-sectional area, and only the piping near the waste input section at a limited terminal is made thinner than the transportation piping 5. However, since the transport pipe 5 for waste treatment gradually branches to reach the waste input port, the total length of the intermediate transport pipe 5 is extremely long, and the construction cost thereof is enormous. Furthermore, this method has the disadvantage that it takes a long time to operate the center equipment such as the blower 11 and the separator 7.

Therefore, we put together a relay station that consolidates the local garbage input sections to some extent, and the relay station is equipped with an air separator, a storage/discharge device, a dust collector, and a blower in the same way as the central processing unit, and once the garbage is collected at the relay station, it is further processed by the central processing unit. A device that collects dust by suction has been proposed. However, in this method, the transportation piping from the local garbage input section to the central processing unit has almost the same cross-sectional area, so the construction cost of the transportation piping is not cheap, and the transfer station is not equipped with a dust collector and a blower. There must be.

Furthermore, in the invention of Japanese Patent Publication No. 54-16358, the relay station is equipped with only a separator and a storage/discharge machine, and the garbage collected from the local garbage input section is sucked up by one blower of the central processing unit and sent to the relay station once. The dust stored and collected at the relay station is further sucked up by the blower. In this case, when garbage is collected by region, a blower capable of transporting the garbage from the relay station to the central processing unit is constantly operated, which increases running costs. In addition, regarding the transportation piping, each transportation piping from the local garbage input section to the central processing unit has approximately the same cross-sectional area based on the amount of suction air, so the construction cost of the transportation piping will not be reduced, and the collection of local garbage is The disadvantage is that it takes time because each transport pipe is required.

The first invention of the present application aims to solve the above-mentioned problems of the conventional pneumatic transport method for waste by providing a pneumatic transport method that can speed up the collection of waste and reduce the running cost of the central processing unit. be.

The second invention of the present application, in addition to the object of the first invention of the present application, aims to reduce the construction cost of transportation piping.

A common relay station with a separator equipped with a valve device that can be connected to the secondary transport piping will be installed, and the relay station will be connected and distributed to each waste input section through the primary transport pipe, and each relay station will be bundled as appropriate. The terminals are connected to a common central processing unit by secondary transport piping, and each relay station collects waste that is discarded at the local waste input section, and the waste collected at each relay station is transferred from the relay station to the central processing unit. In the pneumatic transport method of waste, which is transported through secondary transport piping, the central processing unit has one separator and the full capacity of one separator, and is capable of collecting waste from the waste input area to the transfer station. It is equipped with a blower that outputs a sufficient partial capacity, and is operated with a partial capacity of the blower of the central processing unit, and the air outlet of one relay station connected by one secondary transport pipe is supplied by the valve device. The secondary transport pipe is connected to sequentially collect the waste discarded from the waste input section to each relay station, and then the secondary transport pipe is connected to the waste outlet of the separator provided at one relay station. The method is characterized in that the blower is operated at full capacity with the separator of the central processing unit interposed, and the waste collected at one relay station is transferred to the separator of the central processing unit in sequence for each relay station. It is a method of pneumatic transportation of waste.

The second invention of the present application includes a separator, a plurality of blowers for one separator, and piping that connects all the blowers to the secondary transportation piping via the separator, or connects some of the blowers to the secondary transportation piping. a central processing unit equipped with;
Secondary transport pipes that collectively connect appropriate relay stations to the central processing unit, a large number of garbage input sections arranged in each area, and a primary system that connects each garbage input section collectively to the relay station. A transport pipe, a separator with an air inlet connected to the primary transport pipe and a storage discharger, and a secondary transport pipe connected to an outlet of the storage discharger of this separator and an air outlet of the separator. a relay station with a valve device that communicates with the central processing unit, and the cross-sectional area of each primary transport pipe is equal to the number of secondary transport pipes connected to the central processing unit, with respect to the cross-sectional area of the secondary transport pipe. This pneumatic waste transportation device is characterized in that the ratio is approximately 1/N.

"Example" Hereinafter, an example of the present invention will be described with reference to the drawings.
An example of the means for implementing the first invention of the present application is shown in the embodiment of the second invention of the present application, and the overlapping parts will be explained together, but the explanation of the other will be omitted to avoid duplication.

FIG. 2 shows a side view of the equipment at the relay stations 12a, 12b. The primary transport pipes 5a and 5b in regions a and b are respectively integrated and connected to an air and waste separator 14, and the waste outlet of the separator 14 is connected to a storage discharger 15, and the separator 14 separates air from the air. The pipe 16 is connected to secondary transport pipes 13a and 13b via an on-off valve 17. The outlet of the storage discharger 15 is connected to secondary transport pipes 13a and 13b via a discharge valve 18, respectively. 2
0 is the intake valve. Note that the separator 14 and the storage/discharge device 15 are just one specific example, and any device that can separate dust and air and store dust may be used.

FIG. 3 is a layout diagram of the central processing unit 6. The secondary transport pipes 13a and 13b are divided into deviated inverted Y-shapes at the entrance of the central processing unit 6, and the secondary transport pipe 1
3a and 13b are connected to a dust and air separator 19 through direct communication with the same cross section, and the separator 19 has a dust discharge port connected to a storage discharge machine 21. The air pipes 22a and 22b branched from the secondary transport pipes 13a and 13b in the above-described manner have on-off valves 23a and 23b, respectively.
The air pipe 2 is connected to the air intake port of the separator 19 on the way to the bag filters 24a and 24b via the
5a and 25b are connected to join together via on-off valves 26a and 26b, respectively, and are connected to air pipes 27a and 27b, and air pipes 27a and 27b are connected to bag filters 24a and 24b, respectively, and air pipes 27a and 2
7b comes out from the bag filters 24a, 24b and goes to the blowers 29a, 2 through the flow rate regulating valves 28a, 28b.
It is connected to the suction port 9b. Blower 29a,
Air discharge pipes 31a and 31b are connected to the discharge port 29b.
The deodorizer 32 communicates with the atmosphere through the deodorizer 32 .

The relay stations 12a and 12b have the same function as the relay stations, so if only the function of the relay station 12a is considered, first the on-off valve 17 of the valve device is opened, the discharge valve 18 is closed, and air is taken in from the secondary transport pipe 13a, and then the primary transport pipe is 5a, garbage and air enter the separator 14, where the garbage and air are separated.The garbage is stored in the storage/discharge device 15, and the air flows through the air pipe 16 and the open on-off valve 17 to the secondary transportation pipe 13a. .

Next, when the primary transport pipe 5a connected to the separator 14 is closed, the on-off valve 17 is closed and the discharge valve 18 is opened to suck air from the secondary transport pipe 13a. Atmospheric air is sucked in through the intake valve 20. It comes out from the discharge valve 18 together with the garbage in the storage discharger 15 and is sent to the secondary transportation pipe 13a.

To make the relay station 12a inactive against air suction from the secondary transport pipe 13a, the valve device is closed. That is, the on-off valve 17 and the discharge valve 18 are closed.

In this example, the central processing unit 6 is a blower 29 with the same capacity.
It has a, 29b. Therefore, some blower 2
When operating the fan 9a or 29b, that is, when operating at a partial capacity compared to the full capacity, the same is true, so when operating the blower 29a, when operating the relay station 12a, it is connected to the secondary transport pipe 13b. relay station 12b
The valve device is closed. That is, the on-off valves 23b, 2
6b is always closed. Either or both of the on-off valves 23a, 23a may be opened. Then, when the blower 29a is operated, the air sucked from the secondary transport pipe 13a passes through the air pipe 22a bypassing the separator 19 and the open on-off valve 23a, and reaches the bag filter 24a, or the separator 19 The water then enters the bag filter 24a through the opened on-off valve 26a, or the above-mentioned two routes are divided to reach the bag filter 24a. The air that has passed through the bag filter 24a is sent to the blower 2 via the flow rate adjustment valve 28a.
9a, the air is accelerated and the pressure is increased, and the air is discharged into the discharge pipe 31.
a, and is deodorized by the deodorizer 32 and discharged.

When all the blowers 29a and 29b are operated, air and dust are sucked from either the secondary transport pipe 13a or 13b, but since they are the same, the secondary transport pipe 13a
Specifically, the on-off valves 23a and 23b are closed, and the on-off valves 26a and 26b are opened. The secondary transport pipe 13b is connected to the relay station 12 to which suction is to be performed.
It is closed at b. As a result, garbage and air are sent to the separator 19 through the secondary transportation pipe 13a and separated, the garbage is stored in the storage discharger 21, and the separated air flows from the on-off valves 26a, 26b to the bag filters 24a, 24b. dust is removed, flow rate adjustment valves 28a, 28b, blowers 29a, 29b
The air flows from the blowers 29a and 29b to the air discharge pipe 3.
The air discharged from 1a and 31b is combined and discharged via the deodorizer 32.

Next, let's talk about the piping layout. Although FIG. 2 shows the case where local garbage is collected by dividing it into collection areas, the same applies to the case where it is divided into N areas (N: an integer). In each region, reference numeral 1 is a die chute provided with a waste input port 2 provided in a building, and connected by a discharge valve 3 to primary transport pipes 5a and 5b in that region, respectively. The primary transport pipes 5a, 5b are collected and drawn into relay stations 12a, 12b as a unit.
Local intake valves 33-36, 37-40 are provided at the ends of the primary transport pipes 5a, 5b. Relay stations 12a, 12b and central processing unit 6
They are connected by secondary transport pipes 13a and 13b. Note that a branch secondary transport pipe 13c is additionally connected to, for example, a secondary transport pipe 13a from the facility 12c that generates a large amount of waste. Incidentally, if there is a facility that generates an extremely large amount of garbage, the relay station and the garbage collection area of the relay station are equivalent to a single unit, so they are connected by a transportation pipe directly connected to the central processing unit 6. Here, areas a and b and relay station 12 for them are shown.
The following describes the simplest case in which there are only the relay stations 12a, 12b and the central processing unit 6, but the gist remains the same even if there are many more areas.

For one of the primary transport pipes 5a in region a, only one of the roll intake valves 33 to 36 of the primary transport pipe 5a is opened, and the others are closed.
By sucking air with a partial capacity of the blower, that is, by using the blower 29a, the dust in the dust chute 1 connected to the primary transport pipe 5a via the discharge valve 3 is collected at the relay station 12a.

In addition, the explanation of the function of the local intake valves 33 to 40 when collecting garbage in chute 1 to the relay station will be explained below because only the local intake valve at the end of the primary transport pipe to which the chute 1 belongs is opened. Explanation will be omitted. Relay station 1
In 2a, garbage and air are separated and the garbage is stored. In the same manner, garbage destined for one of the remaining primary transport pipes 5a is collected at the relay station 12a. Therefore, only air flows through the secondary transport pipe 13a.

In region b, as in region a, air is sucked from only one of the primary transport pipes 5b from the central processing unit 6 using a partial capacity of the blower, that is, by using the blower 29b, the primary transport pipe 5 is
Dust chute 1 connected to b via discharge valve 3
The garbage is collected at the transfer station 12b.
The relay station 12b separates dirt and air and has the function of storing dirt. In the same way, garbage is collected at the relay station 12b for one of the remaining primary transport pipes 5b. Only air flows through the secondary transport pipe 13b.

Garbage relay station 12a for areas a and b,
The collection of garbage to 12b is performed simultaneously or independently by controlling the blowers 29a and 29b, respectively.

However, when garbage is collected at the relay stations 12a and 12b at the same time, the on-off valves 23a and 23b of the central processing unit 6 are opened, and the on-off valves 26a and 26b are
By closing each secondary transport pipe 13a, 1
The amount of air flowing through 3b becomes stable.

In the next step, the on-off valve 17 and discharge valve 18 of the valve device of the relay station 12b are closed in order to suck out the garbage stored in the relay station 12a, the on-off valves 23a and 23b of the central processing unit 6 are closed, and the other on-off valves are closed. 26a and 26b are opened to suck air with the full capacity of the blower. That is, when all the blowers 29a and 29b are operated and garbage is collected at the relay stations 12a and 12b in areas a and b, the total amount of air flowing through the secondary transport pipes 13a and 13b is the secondary transport. The waste in the relay station 12a passes through the secondary transport pipe 13a and is collected in the central processing unit 6, where it is separated into dirt and air, and the waste is stored and discharged. Similarly, the garbage stored at the transfer station 12b is in areas a and b.
When collecting garbage at the relay stations 12a and 12b, the total amount of air flowing through the secondary transport pipes 13a and 13b is passed through the secondary transport pipe 13b, and the waste at the relay station 12b is collected through the secondary transport pipe 13b. As described above, the air is collected in the central processing unit 6, air and dust are separated, and the dust is stored and discharged.

According to this pneumatic waste transport method, the single primary transport pipe 5a, 5b that connects the relay station and the local waste input part is used to collect the waste generated at the waste input part.
Since the air flows through only one of the pipes 5a and 5b, a small amount of air is required for transporting the waste, and the cross-sectional area of the primary transport pipes 5a and 5b is made small in order to moderate the wind speed in the primary transport pipes 5a and 5b.

In the central processing unit 6, some blowers 29a
Alternatively, the garbage inputted from the local garbage input port 2 is collected at the relay station 12a or 12b, respectively, using a part of the capacity of the blower by the blower 29b, so that the garbage stored at the relay station is transferred from the relay station to the central processing unit as in the past. This eliminates the uneconomical situation of having to operate the blowers with a large air volume sufficient to suck in the air, that is, the total capacity of the blowers 29a and 29b, also for primary garbage collection, that is, garbage collection to the relay stations 12a and 12b.

Next, an embodiment of the pneumatic transport device for waste according to the second invention of the present application will be described. The explanation of the configurations already explained in FIGS. 2 and 3 will be omitted to avoid duplication. In FIG. 2, the number of regions is equal to the number of secondary transport pipes 13a, 13b coming out of the central processing unit 6, N=2, and the number of relay stations is also N=2. In such a case, if the primary transport pipes 5a and 5b are equal and have an inner diameter of 400 mm, then the secondary transport pipes 13a and 13b have an inner diameter of approximately 600 mm, which is a close standard dimension calculated as √400 ² × 2. or 500
mm inner tube is chosen.

The operation of the second invention of the present application is similar to that of the first invention, but the garbage put into the local garbage input port 2 has a lower wind speed passing through the primary transport pipe 5a during the primary collection of garbage to the relay stations 12a and 12b. As a result, the cross-sectional area of the secondary transport pipes 13a and 13b is approximately twice that of the primary transport pipe 5a, so that the secondary transport pipe 13
The speed of the air in a and 13b is slow, the fluid friction loss of the air is small, and the power is used effectively. In addition, the secondary transport pipes 13a and 13b are large-diameter pipes with an inner end of 600 mm or 500 mm, and are sucked in through the entire blower 19 and transferred to the relay station 12a,
12b can be collected secondary to the central processing unit 6.

FIG. 4 is a perspective view showing a generalized pneumatic transportation method for waste. The above description of the present invention is based on the case where one relay station is provided for each of the two secondary transport pipes 13a and 13b. In FIG. 4, the secondary transport pipe 13a has branch secondary transport pipes 13a-1, 13a-2, 13a-3, and relay stations 12a-1, 12a, respectively.
-2, 12a-3 are provided. That is, the relay stations are appropriately connected to the central processing unit 6 all at once. Beyond the relay station, each group of primary transport pipes 5a-1, 5a-2, and 5a-3 connects to the user's waste input port. 41 is a high-rise residential building,
42 is a single-family house. Reference numeral 43 indicates a location where a large amount of waste is generated, and such a location is directly connected to the branch secondary transportation pipe 13a-3 between the relay station 12a-3 and the central processing unit 6. Similarly, the secondary transport pipe 13b is branched secondary transport pipe 13b-
1 and 13b-2, each with relay station 1
Primary transport piping 5b via 2b-1, 12b-2
-1,5b-2 group connects to the user's garbage input port.

In the above explanation, the relay station assumes that garbage is transported only from the relay station to the central processing unit, but it is also possible to selectively send the garbage to the central processing unit at the relay station, and also to carry out the garbage collected at the relay station. It may be possible to do so.

In this case, garbage collection is performed by first using the blowers of the central processing unit 6 and the secondary transport pipes 13a and 13b, respectively.
The on-off valve 17 of the relay station 12a-1 is opened to suck only more air, and the discharge valve 3 is closed to set the garbage collection state to the relay station 12a-1 for each pipe of the primary transport pipe 5a-1 group.
1. Finish collecting the garbage. Next, the on-off valve 17 of the relay station 12a-2 is opened, and the discharge valve 3 is closed to set the garbage collection state to the relay station 12a for each pipe of the primary transport pipe 5a-2 group.
- Collect garbage in 2. Garbage is accumulated at the relay station 12a-3 in exactly the same manner. Relay station 12b connected to secondary transportation pipe 13b-
1 and 12b-2, garbage is accumulated in the same manner.

Next, as shown in FIG.
Garbage is collected in the central processing unit 6 for each relay station addressed to one of a-3, 12b-1, and 12b-2.

〔Effect of the invention〕

The first invention of the present application is capable of regionally bulking up a large number of garbage input sections, connecting the garbage outlet side and the air outlet side selectively to a central processing unit at a point relatively close to these units, and connecting them to secondary transportation piping. A common relay station with a separator equipped with a valve device will be installed, and the relay station will be connected to each waste input section through primary transport piping, and each relay station will be distributed in bulk to the common central processing unit as appropriate. Connected by transport piping, garbage discarded at the local waste input section is once collected at each relay station, and the garbage collected at each relay station is transferred from the relay station to the central processing unit through secondary transport piping. In the method of pneumatic transportation of waste, the central processing unit includes one separator and a blower that has the full capacity of one separator and a partial capacity that is sufficient to collect the waste from the waste input area to the transfer station. In addition, the blower of the central processing unit is operated at a partial capacity, and the secondary transport pipe is connected to the air outlet of one relay station connected by one secondary transport pipe by the valve device to collect waste. The waste discarded from the input section is sequentially collected at each relay station, and then the secondary transport pipe is connected to the waste outlet of the separator installed at one relay station, and the separator of the central processing unit is interposed. This pneumatic waste transportation method is characterized by operating the blower at full capacity and transferring the waste collected at one relay station to the separator of the central processing unit in turn for each relay station. The primary collection of garbage to the relay station is performed by a portion of the capacity of the blower of the central processing unit, and the pressure loss in the secondary transport piping is small, so running costs are reduced. Further, since the capacity of the blower of the central processing unit can be divided to perform the primary collection of garbage to a plurality of relay stations at the same time, the garbage can be collected quickly. Furthermore, since as much garbage as is present at the relay station is continuously transported from the relay station to the central processing unit, transportation efficiency is high and power costs are also reduced from this point of view.

The second invention of the present application includes a separator, a plurality of blowers for one separator, and piping that connects all the blowers to the secondary transportation piping via the separator, or connects some of the blowers to the secondary transportation piping. A central processing unit equipped with a central processing unit, secondary transportation pipes connected to the central processing unit, appropriate relay stations, a large number of garbage input units arranged in each region, and a plurality of garbage input units that collectively connect each garbage input unit. a separator having an air inlet connected to the primary transport piping and a storage discharger; an outlet of the storage discharger of the separator connected to an air outlet of the separator; a relay station equipped with a valve device selectively connected to the secondary transport pipes connected to the central processing unit; Since the pneumatic waste transport device is characterized in that the number of secondary transport pipes is approximately 1/N, the cross-sectional area of the primary transport pipes can be significantly reduced in addition to the effects of the first invention of the present application. Therefore, the construction cost of the primary transportation piping, which has the longest total length, can be reduced.
