Abstract

<P>PROBLEM TO BE SOLVED: To simply suction and recover, for example, a posttreatment article and a powder such as a decomposition fermentation product of a garbage decomposed and fermented by a microorganism such as garbage decomposition bacillus and to reduce burden of a worker by shortening a working time. <P>SOLUTION: After the carrier which carries the microorganism for decomposing the garbage and the garbage are thrown into a treatment vessel to decompose the garbage, the posttreatment product is suctioned by a suction pipe. The posttreatment product is separated from a suction stream by turning the suction stream containing the suctioned posttreatment product along an inner peripheral surface of a vertical cylindrical part and the posttreatment product is stored into a storage vessel. In this case, since the posttreatment product is separated by the turning flow without being drawn to a suction means side and can be stored into the storage vessel, the labor of a manual recovery by a scraping out work is omitted. Therefore, the work can be quickly carried out and a shortening of the working time can be realized. The product to be suctioned is not limited to the posttreatment product and may be the powder. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a suction device that sucks and collects a processed product such as a decomposed fermented product or powder of raw garbage that has been decomposed and fermented by a garbage-degrading bacterium, and a separator for the suction device.

  Conventionally, for example, raw garbage generated at home or the like is generally collected in, for example, a public waste disposal facility and incinerated by an incinerator. However, due to the occurrence of the dioxin problem, a microbial fermentation decomposition method has been proposed as a new treatment method to replace incineration, and in order to effectively use the decomposed fermented material obtained by the action of garbage decomposing bacteria, the compost raw material Applicability as

  For example, as a microbial decomposition fermentation type garbage processing machine for business use, an aerobic microorganism that is a garbage decomposing bacterium and a carrier such as cedar chip, sawdust, coconut shell pulverized material that supports the garbage decomposing bacterium Is put in a processing container in advance, and a method for obtaining a primary fermented product by decomposing the raw garbage by adding the raw garbage to this container and stirring and mixing it, and further fermenting with the carrier. It is known (for example, refer to Patent Document 1). Thereafter, the primary fermented product is taken out from the processing container, and subjected to secondary treatment such as moisture concentration adjustment or nitrogen concentration adjustment at another location, so that the fermented product is fully ripe and, for example, agricultural compost (2 Next fermented product).

JP 2002-316128 A (paragraphs 0007 to 0009, FIGS. 1 and 2)

  An example of the above-described garbage processing machine will be described with reference to FIGS. 6 and 7. In FIG. 1, reference numeral 1 denotes a bottom having a semicylindrical shape for introducing and processing garbage, for example, with a capacity of 200 to 200. The processing container 1 is supported by a support 11. An input port 13 provided with an openable / closable lid 12 is formed on the upper surface of the processing container 1, and a carrier carrying garbage and garbage-decomposing bacteria from the input port 13 is provided in the container. The fermented material after being treated with the garbage and disposed of at the bottom is discharged from a discharge port 14 provided with an openable / closable shutter 14a provided on the bottom surface (not shown in FIG. 6). A heater 15 for heating the contents in the container to a predetermined temperature is provided on the side surface of the processing container 1, and an air supply pipe 16 and an exhaust pipe 17 are connected to each other. A rotating shaft 2 extending in the lateral direction is disposed in the processing container 1, and a plurality of stirring arms 21 are provided in the longitudinal direction of the rotating shaft 2 at intervals. The rotating shaft 2 is connected to a motor 23 via a belt mechanism 22, and the rotating shaft 2 is rotated by driving the motor 23, and the contents in the processing container 1 are stirred by the stirring arm 21. Has been.

  In order to process garbage using the garbage processing machine as described above, first, the lid 12 is opened and a carrier carrying garbage-decomposing bacteria is put into the processing container 1, and the moisture content is 20 to 20%. The moisture is adjusted to 60% by weight. Thereafter, raw garbage is put in, and the heater 15 heats the contents in the container to be, for example, 30 ° C. to 50 ° C., and supplies and exhausts air through the air supply pipe 16 and the exhaust pipe 17. Do. As a result, the garbage is gradually decomposed and finally fermented with the carrier to become a primary fermented product. When the decomposition capacity of the input garbage is reduced to a certain level, as shown in FIG. 8, the stirring arm 21 is rotated and the shutter 14a is opened to discharge the primary fermentation product from the discharge port 14, for example, a bag. The work to pack 14b is performed. The primary fermented product packed in the bag 14b is transferred to another place for secondary treatment, and is subjected to a predetermined treatment such as adjustment of moisture concentration and nitrogen concentration, for example, and composted by ripeness. The On the other hand, new garbage decomposing bacteria and a carrier are introduced into the processing container 1 which has been emptied after the primary fermented product is discharged, and the processing of the garbage is performed again.

  However, since the garbage generally contains water and oil at a ratio of 10: 1, for example, the viscosity of the fermented product often gradually increases with the progress of the decomposition treatment by the decomposing bacteria. When the amount of oil increases, some of the oil may become sludge or lump. For this reason, the fermented product cannot be completely discharged even if the pushing action of the stirring arm 21 is relied on, and the residue remaining in the processing container 1 must be scraped off manually by the operator, for example, by stopping the stirring arm 21. did not become. Furthermore, it takes time and effort to remove residues on the surface of the stirring arm 21 having a complicated shape and the corners of the processing vessel 1 that are difficult to reach and to carry the bag 14b containing the residues. Therefore, for example, the work time has been extended, such as a half-day work with four persons for the 200-liter processing container 1. In particular, when the decomposed bacteria cause anaerobic fermentation due to insufficient air permeability in the processing container 1 when processing garbage, the burden on the operator is great because a strong odor is scattered around.

  Although it is conceivable to increase the opening area of the discharge port 14 to facilitate discharge, it is necessary to provide the discharge port 14 in the vicinity of the lower end of the processing container 1, so that leakage of the input during processing is prevented. Furthermore, it is difficult to process the discharge port 14 along the curved surface of the bottom surface. Although it is conceivable that the primary fermented product is discharged from the inlet 13 by turning the processing container 1 upside down, the garbage processing apparatus tends to increase in size. For example, when it is attempted to process about 50 kg of garbage per day, the capacity is increased. A processing container 1 of about 600 liters must be used, which is not realistic.

  On the other hand, the inventors have examined a technique for sucking and collecting the residue that could not be discharged from the discharge port 14 with a vacuum cleaner, and a specific example thereof is shown in FIG. In the figure, reference numeral 24 denotes a suction nozzle for sucking a residue. For example, an operator inserts the suction nozzle 24 into the processing container 1 to suck the residue. Reference numeral 25 denotes an exhaust pump for forming a suction flow. This exhaust pump 25 is connected to the suction nozzle 24 through, for example, a suction path 26, and in order to separate the sucked residue from the suction flow. An intermediate tank 27 is provided as a separating means. In such a configuration, first, the shutter 14a is opened and the primary fermented material in the processing container 1 is discharged from the discharge port 14 to some extent, and then the residue is sucked by the suction nozzle 24 together with the suction flow which is an air flow and the intermediate tank 27. Introduce in. Here, a residue (primary fermentation product) having a large specific gravity is accumulated at the bottom of the intermediate tank 27, and the air flow from which the residue is separated is discharged to the outside by the exhaust pump 25. However, since the intermediate tank 27 has a narrow flow path between the air flow inlet 27a and the outlet 27b, a part of the residue enters the exhaust pump 25 and adheres to the inside to damage the exhaust pump 25. There is a concern to let you. Further, there is a concern that the dust of the residue is scattered around and mixed with the exhaust flow of the exhaust pump 25 exhausted to the outside, spreading the bad odor. In order to enhance the dust collection effect of the intermediate tank 27, it is also possible to provide a fine filter so as to cover, for example, the inlet of the discharge port 27b. There is a concern that the required suction pressure cannot be secured.

  The present invention has been made based on such circumstances, and an object thereof is to easily treat a processed product or a powder such as a decomposed fermented product of garbage that has been decomposed and fermented by microorganisms such as a garbage-degrading bacterium. An object of the present invention is to provide a suction device that can be sucked and collected and a separator for the suction device. Another object is to reduce the burden on the operator by shortening the working time.

The present invention relates to a suction device that sucks and collects a processed product after putting a carrier supporting microorganisms for decomposing garbage and garbage into a processing container and decomposing the garbage,
A suction pipe for sucking in the processing object in the processing container;
A storage container for storing the processed material sucked by the suction pipe;
A cylindrical portion that is provided at the upper portion of the storage container and is connected to the suction pipe, and for swirling a suction flow including a processed product sucked from the suction pipe along an inner peripheral surface thereof;
An exhaust port that opens to the upper part of the cylindrical part and forms an upward flow passing through the central part of the swirling flow;
A suction means connected to the exhaust port and for forming a suction flow in the suction pipe through the cylindrical portion;
By forming a swirl flow in the cylindrical portion, the processed material is separated from the suction flow and dropped into the storage container.

The cylindrical part may have the same diameter on the upper side and the lower side, or may extend outward on the lower side. Further, the storage container may have a configuration in which a filter unit is provided for separating foreign matter from the sucked aspirate. As a method for forming a swirl flow in the cylindrical body, for example, a suction pipe may be connected to the side surface of the cylindrical portion in a tangential direction. However, for example, the suction pipe may be connected to the side surface or the upper surface of the cylindrical portion. A structure may be provided in which a guide is provided for connecting and guiding the airflow blown from the connection port to the inner peripheral surface. In addition, it is not meaningful to use the square tube portion instead of the cylindrical portion to form the swirl flow, but even when the square tube portion is used, it is included in the cylindrical portion referred to in the present invention and included in the technical scope of the present invention. It is. Moreover, it is preferable that the diameter of a cylindrical part is 3 times or more of the diameter of an exhaust port.
The suction device of the present invention can be applied not only to suction of a processed product after decomposing the garbage, but also to devices for sucking other powders.

Further, the separator for the suction device of the present invention includes a lid that closes a storage container for storing a processed product,
A cylindrical portion provided on the lid for turning a suction flow containing the processed material along its inner peripheral surface;
A suction port that opens to a side portion of the cylindrical portion and supplies a suction flow containing a processed product to the cylindrical portion;
And an exhaust port for opening an upward flow passing through the central portion of the swirl flow and opening at an upper portion of the cylindrical portion.

  According to the suction device of the present invention, by adopting a configuration in which the primary fermented product (processed product) is collected from the processing container, for example, by the suction means, it is possible to save time and trouble such as scraping off the residue manually, so that the work can be performed quickly. This can be done and the working time can be shortened. Further, by swirling the air flow containing the sucked residue to separate the residue from the air flow, it is possible to prevent dust from entering the downstream side, so that dust adheres to the inside of the exhaust pump. The exhaust pump is less likely to be damaged, and dust is less scattered around the exhaust flow of the exhaust pump. Furthermore, not only the processed material but also the powder is sucked, similarly, the powder can be separated by the swirling flow without being drawn into the exhaust pump and dropped into the storage container.

  Embodiments of the suction device of the present invention will be described with reference to FIGS. In the figure, reference numeral 3 denotes a suction pipe that forms a cylindrical body made of, for example, resin for sucking the primary fermented material in the processing container 1 provided in the garbage processing machine shown in FIGS. 6 and 7. is there. The operator moves while holding the tip of the suction pipe 3 during the suction operation, and is inserted into the processing container 1 to bring the suction port 31 formed at the tip of the suction pipe 3 closer to the target primary fermented product. The primary fermentation product can be sucked by the suction pressure. The primary fermented product that is a processed product contains, for example, 40% by weight of water, and has a wide particle size distribution including, for example, fine particles having a particle diameter of about 0.01 mm to particles having a size of about 50 mm, for example. Is mixed with fibers such as cedar chips, sawdust, and coconut shell pulverized material.

  Reference numeral 4 in the figure denotes a collecting means for separating and collecting the primary fermentation product from the ambient air (air flow) sucked together with the primary fermentation product via the suction pipe 3 (see FIG. 2 in detail). reference). Further, the collecting means 4 is a swirl flow forming unit 40 that is a separation unit for separating the primary fermentation product and the air flow, and a first storage that is a storage unit for storing the separated primary fermentation product. And a container 41. The first storage container 41 is, for example, a cylindrical container. For example, a 200-liter steel or iron drum can is selected so that the worker can carry it. The first storage container 41 has, for example, a filter section 42 that forms a mesh lattice for separating foreign substances, such as spoons, that have been mistakenly introduced during the operation of charging garbage, from the primary fermentation product. The storage container 41 is detachably provided so as to be divided vertically. In addition, 43 is a carrier with a caster, for example, By using such a carrier 43, it is comprised so that an operator can convey the collection means 4 easily.

  In addition, a lid 44 made of, for example, iron that closes the opening is detachably provided at the opening on the upper surface side of the first storage container 41. Further, the swirl flow forming unit 40 that is the separation unit described above is provided with the lid. For example, it is provided in the central region of the body 44. The swirl flow forming unit 40 includes a main body 45 that is a cylindrical tubular body having a diameter of, for example, 250 mm and a height of 350 mm with an opening on the bottom surface side. A suction nozzle 46 that is, for example, a suction port (suction port) having a diameter of 75 mm and extending in a tangential direction with respect to the ceiling surface of the main body 45 is provided. One end of the suction pipe 3 is connected to the suction nozzle 46, and the air flow containing the primary fermentation product sucked from the suction pipe 3 is introduced into the swirl flow forming unit 40 through the suction nozzle 46. In the figure, reference numeral 47 denotes a sealing material, for example, rubber packing, for ensuring the airtightness of the contact surface between the first storage container 41 and the lid 44.

Further, as shown in detail in FIG. 3, an exhaust nozzle 48 that is an exhaust port (exhaust port) having a diameter of, for example, 75 mm is inserted into the center of the ceiling surface of the main body 45 so as to protrude inward by, for example, about 125 mm. It is installed. Since the atmosphere in the main body 45 is sucked and exhausted by the suction means provided in the subsequent stage through the exhaust nozzle 48, the swirl flow and the upward flow formed in the main body 45 interfere with each other as will be described in detail later. and to prevent the particular fine particles of the primary fermentation product to increase flow by air flow is disturbed is evacuated mixed with, the diameter D ₁ of the exhaust nozzle 48, the diameter D ₂ of the main body portion 45 It is preferable to set so that D ₂ ≧ 3D ₁ . Furthermore, it is preferable to select a material with a smooth surface for the inner wall surface of the main body 45, or to manufacture the main body 45 with, for example, iron and smooth the surface by processing. With such a configuration, for example, even when a primary fermented product having a high viscosity enters, it hardly adheres to the wall surface of the main body 45 and becomes a resistance to the swirling flow, so that a swirling flow without turbulence is formed in the main body 45. This is advantageous in that it can be done. That is, in this example, the main body 45, the suction nozzle 46, the exhaust nozzle 48, and the lid 44 constitute a separator.

  Returning to FIG. 1, the suction means 5 for generating a suction flow from the suction port 31 of the suction pipe 3 to the suction drive unit 50 is provided at the subsequent stage of the collection means 4. The suction unit 5 includes a suction drive unit 50 that is a drive unit, and a second storage container 51 for storing the sucked primary fermentation product, and is provided on a side surface of the second storage container 51. The suction nozzle 52 and the exhaust nozzle 48 are connected to each other through a suction path 52, for example, a hose. Further, the suction drive unit 50 is provided with exhaust means, for example, an exhaust pump 53, and the exhaust pump 53 is driven to exhaust the atmosphere in the second storage container 51 to the outside, so that a suction flow is formed. It is comprised so that. In the figure, reference numeral 55 denotes a partition wall for suppressing the primary fermented product sucked into the second storage container 51 from the suction nozzle 52 from being sucked into the discharge port 54.

  For example, a steel or iron drum can is used for the second storage container 51, as in the case of the first storage container 41 described above, and is configured to be transported by being placed on a carriage 56 with casters. However, this second storage container 51 is not intended to positively store the sucked primary fermented product unlike the first storage container 41 described above. It is provided as a so-called safety tank in order to suppress the primary fermented material that could not be recovered due to insufficient separation action of the collecting means 4 from entering the exhaust pump 53. That is, in the steady state, the primary fermented product is almost completely separated from the air flow in the swirl flow forming unit 40. For example, the exhaust pump 53 may be directly connected to the exhaust nozzle 48 of the swirl flow forming unit 40. By providing the second storage container 51, it is possible to more reliably suppress the primary fermented product, particularly the dust, from entering the exhaust pump 53. In order to more reliably prevent the primary fermentation product from being mixed into the exhaust pump 53, for example, a filter mechanism such as a Saran filter may be provided between the second storage container 51 and the exhaust pump 53. Even in this case, the primary fermented product is almost completely recovered by the repairing means 4 and only a small amount enters the second storage container 51, so the Saran filter is rarely clogged.

  As mentioned above, the primary fermented product becomes highly viscous depending on the amount of water and oil, and in some cases, for example, it is in the form of sludge or lumps in which the fibers of the carrier are intertwined. For example, the suction pipe 3 is clogged in the middle of the suction pipe 3, so that at least the suction pressure of the suction port 31 of the suction pipe 3 is desirably set to a predetermined suction pressure, for example, 20 kPa or more. Therefore, it is preferable to use, for example, a pump having a motor output of 3 KW or more and a suction work rate of 300 W or more so that the predetermined suction pressure can be secured. Furthermore, as the suction means 5, for example, an industrial cleaner having a higher suction force than that for home use can be applied, and for example, an industrial cleaner JE-560 manufactured by Mitsutoshi Machinery Co., Ltd. can be used.

  Then, the process of attracting | sucking and collect | recovering the primary fermented material in the processing container 1 using the suction device of this invention is demonstrated, referring FIG. First, while rotating the stirring arm 21, the shutter 14a is opened, the primary fermented material is discharged from the discharge port 14, and packed into, for example, a bag 14b. Thus, when the primary fermented product is discharged from the processing vessel 1 to some extent, the rotating operation of the stirring arm 21 is stopped, and subsequently the primary fermented product remaining in the processing vessel 1 is recovered using the suction device of the present invention. Work is done. Assuming that this primary fermented product is called a residue, first, for example, the operator inserts the suction pipe 3 into the processing container 1 through the insertion port 13, and operates the exhaust pump 53 to start the suction operation. The tip of the suction pipe 3 is moved and the residue in an arbitrary place is sequentially sucked.

  The residue sucked into the suction pipe 3 is introduced into the main body 45 of the swirl flow forming unit 40 through the suction nozzle 46 at a predetermined flow rate. Then, as schematically shown in FIG. 5, the suction flow, which is an air flow including the residue introduced into the main body 45 from the tangential direction, is swung downward along the inner peripheral surface of the main body 45. A swirling flow that flows toward is formed. On the other hand, since the atmosphere in the main body 45 is discharged upward through the exhaust nozzle 48 by the suction action of the exhaust pump 53 at the rear stage, the central portion of the swirling flow (the central portion of the main body 45) is removed. An upward flow flowing through is formed.

  That is, in the main body 45, an air flow called a cyclone flow is formed which includes a swirling flow that flows downward while swirling along the inner peripheral surface, and an upward flow that flows upward through the center of the swirling flow. By forming this cyclone flow, the centrifugal sedimentation action acts on the solid particles (residues) in the main body 45, and the residues are separated from the airflow. More specifically, the centrifugal force is generated when the air flow including the residue introduced through the suction nozzle 46 swirls in the main body 45, and at this time, the residue (solid particles) having a higher specific gravity is more than the air. Since a large centrifugal force acts, the residue is separated from the air flow by being brought closer to the inner wall surface side of the main body 45 and densified. Then, when the swirling flow is discharged from the bottom opening of the main body 45, the residue falls in the first storage container 41 due to the sedimentation action due to its own weight, and foreign substances such as a spoon, for example, pass through the filter mechanism 42. It is removed and deposited on the bottom of the first storage container 41. In addition, the air flow from which the residue has been separated is reversed in the direction to become an upward flow, discharged from the exhaust nozzle 48, introduced into the second storage container 52 through the second suction path 52, and further exhausted. The air is exhausted to the outside through the pump 53.

  When the first storage container 41 becomes full by continuing the suction operation or when a predetermined amount of residue is stored in the container, the suction operation is temporarily stopped and the lid body 44 is stored in the first storage container. The container 41 is removed from the container 41 and replaced with another container, or, for example, refilled into a bag or the like to empty the storage container 41, and then the first storage container 41 is attached again to resume the suction operation.

  According to the present embodiment, the residue in the processing container 1 is sucked with the suction pipe 3 and collected by using the suction device, so that the scraping work of the residue that has been performed manually is omitted. be able to. As a result, the collection operation can be performed easily, and as a result, the operation time can be shortened. And by applying this example, as described in the column of “Prior art”, it was invented that what used to be half-day work with 4 people can be shortened to about 1 hour with 2 people. They have confirmed. Further, since the tip of the suction pipe 3 can be sucked close to an arbitrary place, it is not necessary to scrape the residue in the processing container 1 in one place, and the surface of the stirring arm 21 and the corner of the processing container 1 are not required. Residue adhering to difficult-to-reach parts such as parts can be sucked in easily, so that the collection accuracy is high, so that there is no residue in the processing container 1 after the collection operation or the amount is very small. . As a result, it is possible to save the trouble of performing a new cleaning operation after the collection operation as before. Furthermore, since the residue can be sucked in while sucking the ambient air from the suction pipe 3, the scattering of the dust of the residue from the inlet 13 can be suppressed, so that the bad odor is less likely to spread.

  Furthermore, according to the present embodiment, the swirl flow forming portion 40 is set so that the diameter of the main body portion 45 is three times or more the diameter of the discharge nozzle 48 to increase the air flow including the sucked residue. By making it the structure which isolate | separates a residue by swirling, a residue can be isolate | separated from an air flow with the precision of several microns. For this reason, since it is suppressed that a residue mixes in the air flow which goes downstream, the residue adheres inside the exhaust pump 53, and there is little damage to the said exhaust pump 53. Furthermore, since the dust of the residue is prevented from being exhausted to the surroundings together with the exhaust flow of the exhaust pump 53, it is possible to ensure a clean working environment with less bad odor and less burden on the operator. .

  Furthermore, according to the present embodiment, the main body 45 of the swirl flow forming unit 40 is formed in a cylindrical shape with the same diameter on the upper side and the same diameter on the bottom side, so that a highly viscous sludge-like residue is formed. Even if an object is sucked, it is hardly clogged in the middle, and the residue can be easily separated from the air flow. That is, in this example, fine particles that easily enter the exhaust pump 53, highly viscous sludge-like or lump-like residues containing moisture or oil, and fibers of the carrier are also sucked together. Therefore, in order to separate them by the common collecting means 4, for example, if the bottom portion used in a general cyclone is configured to have a throttle mechanism that reduces the diameter as it goes downward, sludge is contained in this throttle mechanism. Or a lump or a fiber is clogged and the bottom side opening is blocked. However, in this example, since such a throttling mechanism is not provided, sludge or lump or fiber can be separated and dropped from the air flow. Further, as described above, by combining the structure that forms a swirling flow that largely swirls within the main body 45 by setting the diameter of the main body 45 to be three times or more, a common collecting means (a swirling flow formation) Part 40) can be used to collect fine particles (dust) together with sludge and fibers. The main body 45 may have a configuration in which the diameter on the bottom side is made larger than the diameter on the upper side, or further, the bottom side is widened outward.

  Furthermore, according to the present embodiment, since the apparatus configuration is not complicated and can be easily carried by an operator, it is easy to carry the first storage container 41 storing the residue. The service person of the manufacturer / sales manufacturer can go around each household with the suction device and collect the residue. That is, since it is not necessary to provide a suction device for each garbage processing machine, the cost and size of the garbage processing device can be reduced as a result. Furthermore, since it is not necessary to provide the discharge port 14 on the bottom surface of the processing container 1, the structure of the garbage processing machine can be simplified.

  In the present embodiment, the method is not limited to a method in which the primary fermented product is discharged to some extent through the discharge port 14 and then the residue is sucked and collected. For example, all of the primary fermented product in the processing container 1 is sucked and collected. You may make it do. Even if it is such a structure, the effect similar to the above-mentioned case can be acquired, Furthermore, since the discharge port 14 does not need to be formed in the processing container 1, the apparatus structure of a garbage disposal apparatus becomes simple. This is advantageous.

  Moreover, in this invention, a processed material is not restricted to a primary fermented material, If it is a powder containing a water | moisture content or oil, it can apply. One example is livestock feces. Even in this case, the powder can be separated by the swirl flow without being drawn into the exhaust pump and dropped into the storage container. Further, the present invention is not limited to the configuration in which the suction nozzle 46 is provided in the tangential direction. For example, the suction nozzle 46 is provided on the side surface or the upper surface of the main body 45 and a guide for guiding the airflow blown from the suction nozzle 46 to the inner peripheral surface is provided. It may be a structure.
