Description

  The present disclosure relates to a transport device, and more particularly, to a transport device that transports a conveyed object along a transport path that includes an upward rising path.

  A chain-type bucket elevator is known as a device for conveying a lump, granular, or powdery conveyed material (bulk) upward. A chain-type bucket elevator generally includes a plurality of buckets, an endless link chain to which the bucket is attached, and upper and lower sprockets around which the link chain is wound. Each transport component including the bucket, the link chain, and the sprocket is housed in a casing from the viewpoint of preventing dust from scattering.

  In the bucket elevator, the link chain is suspended from the upper sprocket toward the lower sprocket. When the lift of the bucket elevator is increased, the verticality of each member such as a casing and a rail for guiding the link chain tends to affect the verticality of the link chain, so that the link chain is easily biased with respect to the upper and lower sprockets. Even if each member is installed vertically with high accuracy, if the lift is large, the axis of the upper and lower sprockets will be displaced due to the environment around the bucket elevator, such as temperature, wind, or solar radiation, and the link chain will not move. May be biased against As a result, the sprocket and / or the link chain will wear abnormally, possibly breaking the link chain.

  A belt conveyor is also known as a device for transporting bulk materials upward. The belt conveyor has a configuration in which a belt is wound around upper and lower pulleys. In the belt conveyor, even if the positions of the shafts of the upper and lower pulleys are slightly shifted, abnormal wear and breakage of the belt hardly occur.

  Patent Literature 1 describes a belt conveyor including a driving belt wheel, a tail belt wheel, and a rubber belt wound around these belt wheels. The belt conveyor includes a vertical portion, upper and lower steep portions disposed so as to sandwich the vertical portion, and upper and lower horizontal portions continuous with each steep portion. In the lower horizontal portion, the conveyed material, which is a bulk material, and the spherical medium are alternately supplied to the rubber belt. At the steeply inclined portion and the vertical portion, the rubber belt to which the transported object and the medium are supplied is deformed into a cylindrical shape. Thereby, the medium is partitioned in the rubber belt. The rubber belt transports the transported object upward while preventing the transported object from falling by the medium.

  In the belt conveyor of Patent Document 1, a medium is collected from a rubber belt at an upper horizontal portion, and the medium is supplied to the rubber belt again at a lower horizontal portion. That is, in the belt conveyor disclosed in Patent Literature 1, it is necessary to transport the medium only by the volume integral in addition to the transport of the transported object. For this reason, it is not possible to ensure high transport efficiency for the transported object. In particular, when the supply interval of the medium is short and the total volume of the medium that needs to be transported increases, the transport efficiency of the transported object decreases.

  On the other hand, in the belt conveyor described in Patent Literature 2, when the belt body is rolled into a cylindrical shape, a partition plate is formed by a plurality of fin-shaped pieces. Each fin is fixed to a belt body. For this reason, the belt conveyor of Patent Literature 2 does not need to transport the fin-shaped small pieces, and the transport efficiency does not decrease as in the belt conveyor of Patent Literature 1.

JP-A-58-36804 JP 09-328209 A

  In Patent Literature 2, the belt body deforms into a cylindrical shape after receiving the conveyed object. At this time, in the inside of the belt body, the adjacent fin-shaped pieces overlap each other to form a partition plate. When the cylindrical belt body is in a vertical or steeply inclined state, a conveyed product is placed on the partition plate. However, in a partition plate composed of separate fin-shaped pieces, a conveyed object may be bitten between the fin-shaped pieces. When the belt body travels on a vertically or steeply conveyed conveyance path in a state where the conveyed object is caught between the fin-shaped pieces, the conveyed conveyed object may drop.

  An object of the present disclosure is to provide a transport device capable of suppressing a fall of a transported object.

  A transport device according to the present disclosure transports a transported object along a transport path including an upwardly rising path. The transfer device includes a belt and a plurality of partitions. The belt travels on a transport path. The plurality of partitions are arranged in the running direction of the belt. The plurality of partitions are fixed to one surface of the belt. The portion of the belt traveling on the ascending path is deformed along the outer periphery of the row of the partition portions to form a cylindrical portion. The tubular portion wraps the article. Each of the partitions has an undivided mounting surface. The transported object in the cylindrical portion is mounted on the mounting surface.

  According to the transport device, the transport object can be prevented from falling.

FIG. 2 is a schematic configuration diagram of the transport device according to the first embodiment. FIG. 3 is a perspective view of a lower end portion of the transport device shown in FIG. FIG. 4 is a side view of a lower end portion of the transport device shown in FIG. FIG. 5 is an enlarged view showing a part of a rising path of the transport device shown in FIG. FIG. 6 is a perspective view of the upper end of the transport device shown in FIG. FIG. 7 is a schematic configuration diagram of a transport device according to the second embodiment. FIG. 8 is an enlarged view showing a peripheral portion of a supply device of the transport device shown in FIG. FIG. 9 is a schematic configuration diagram of a transport device according to the third embodiment. FIG. 10 is an explanatory diagram of a modified example of the transport device according to each embodiment.

  The transport device according to the embodiment transports a transported object along a transport path including an upward rising path. The transfer device includes a belt and a plurality of partitions. The belt travels on a transport path. The plurality of partitions are arranged in the running direction of the belt. The plurality of partitions are fixed to one surface of the belt. The portion of the belt traveling on the ascending path is deformed along the outer periphery of the row of the partition portions to form a cylindrical portion. The tubular portion wraps the article. Each of the partitions has an undivided mounting surface. The transported object in the cylindrical portion is placed on the placement surface (first configuration).

  In the first configuration, when the belt travels on the ascending route, the belt is deformed into a cylindrical shape along the outer periphery of the row of the partition portions. The inside of the belt is partitioned into a plurality of spaces by a partition. In each space in the belt, the conveyed material is placed on the placement surface of the partition by gravity. Since the mounting surface is non-divided, the transported object does not bite even if the transported object is loose. Therefore, it is possible to prevent the transported object from falling when the transported object is transported upward.

  In the above transport device, the belt may have a plurality of partition supports. The partition support portions are provided on one surface of the belt corresponding to the plurality of partition portions. Each of the partition support portions supports the corresponding partition portion in the tubular portion of the belt (second configuration).

  According to the second configuration, in the tubular portion of the belt, each partition is supported by the partition support. Therefore, it is possible to prevent the partition portion from hanging down due to the weight of the conveyed object. As a result, collapse of the space defined by the two partition portions adjacent to each other in the traveling direction in the belt is less likely to occur.

  The transfer device may further include a charging unit and a regulating unit. The input section can input the conveyed object to a curved portion of the belt that is curved with one surface inside. The restricting portion has an outer shape along the outer peripheral portion of the partition exposed from the curved portion. The regulating section regulates the supply amount of the conveyed material from the input section to the curved portion (third configuration).

  The transport device according to the third configuration includes a regulating unit that regulates a supply amount of the transported object to the belt. The outer shape of the restricting portion is formed along the outer peripheral portion of the partition. With such a shape, the restricting portion prevents the transported material exceeding the partition portion from being supplied to the belt when viewed in the running direction of the belt. Therefore, it is possible to supply a proper and constant amount of the conveyed material to the space located between the two partition portions adjacent to each other in the traveling direction on the belt.

  In the above-described transport apparatus, the loading section may open a part of the tubular portion and feed the transported material into the tubular portion on the ascending route (fourth configuration).

  For example, in each of the above-mentioned patent documents, a conveyed material is thrown into a belt in a horizontal portion of a conveying path. On the other hand, according to the fourth configuration, since the conveyed material is thrown into the belt on the ascending route, it is not necessary to provide a horizontal portion for feeding the conveyed material in the conveyed route. Therefore, the transport device can be made compact.

  In the above-described transport device, each of the partition portions may be formed in a plate shape. In this case, each of the partition portions can have a main surface that intersects the traveling direction and includes the mounting surface (fifth configuration).

  According to the fifth configuration, each partition is plate-shaped, and the mounting surface for mounting the conveyed article is provided on the main surface of the partition. This makes it easier for the transported object to be held on the mounting surface, and it is possible to more reliably prevent the transported object from dropping during the transport.

  The transfer device may further include a guide tube. The guide tube is provided on the ascending path. The cylindrical portion travels inside the guide tube (sixth configuration).

  According to the sixth configuration, since the shape of the tubular portion of the belt can be maintained by the guide tube, it is possible to prevent the tubular portion from opening and the conveyed object from falling. Further, since a roller for maintaining the shape of the cylindrical portion, a driving mechanism thereof, and the like are not required, the transport device can be simplified.

  The guide tube may be configured such that gas is injected when the tubular portion is running inside the guide tube (seventh configuration).

  According to the seventh configuration, it is possible to reduce the frictional resistance of the guide tube with respect to the cylindrical portion of the belt.

  The guide tube may include a curved portion composed of a single or a plurality of tube members (eighth configuration).

  According to the eighth configuration, when the guide tube has a curved portion, that is, when the ascending path where the guide tube is provided includes a curved path, in the curved portion, the belt is formed into a tubular shape by a single or a plurality of pipe members. Is maintained. Therefore, in the curved portion of the ascending path, a roller for maintaining the belt in a cylindrical shape, a driving mechanism thereof, and the like can be eliminated or reduced. For this reason, the transport device can be simplified.

  Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or corresponding components have the same reference characters allotted, and description thereof will not be repeated.

<First embodiment>
[Gas treatment system]
The transfer device according to the first embodiment is used, for example, in a gas processing system. FIG. 1 is a schematic configuration diagram of a gas processing system 100 that can use the transport device according to the first embodiment.

  The gas treatment system 100 is a system that treats exhaust gas from combustion equipment such as an incinerator, a boiler, or a sintering machine. The exhaust gas contains harmful substances such as nitrogen oxides (NOx), sulfur oxides (SOx), and dioxins. The gas treatment system 100 is used to remove harmful substances from exhaust gas.

  As shown in FIG. 1, the gas processing system 100 includes an adsorption tower 1, a regeneration tower 2, and transport devices 31 and 32.

  The adsorption tower 1 has a denitration layer 11 and a desulfurization layer 12. The denitration layer 11 includes a plurality of denitration containers 111. The desulfurization layer 12 is arranged below the denitration layer 11. The desulfurization layer 12 includes a plurality of desulfurization containers 121. The desulfurization container 121 is provided corresponding to the denitration container 111. Each of the desulfurization vessels 121 is connected to a corresponding denitration vessel 111.

  Each denitration container 111 and each desulfurization container 121 are filled with a granular adsorbent. The adsorbent is, for example, activated carbon. As shown by an arrow in FIG. 1, exhaust gas is supplied to the desulfurization container 121. The exhaust gas passes through the desulfurization container 121 and the denitration container 111 in order. When the exhaust gas passes through the desulfurization container 121, SOx in the exhaust gas comes into contact with the adsorbent in the desulfurization container 121 and is adsorbed. When the exhaust gas passes through the denitration container 111, NOx in the exhaust gas contacts the adsorbent in the denitration container 111 and is decomposed. The exhaust gas from which SOx and NOx have been removed is discharged from the adsorption tower 1.

  During operation of the gas treatment system 100, the adsorption tower 1 receives and discharges the adsorbent. The adsorbent is supplied from the upper end of the adsorption tower 1 into the denitration vessel 111 and the desulfurization vessel 121, and moves downward in the denitration vessel 111 and the desulfurization vessel 121. After adsorbing SOx in the exhaust gas, the adsorbent is discharged from the lower end of the adsorption tower 1 and sent to the regeneration tower 2.

  The regeneration tower 2 receives the adsorbent that has adsorbed SOx. The adsorbent is supplied from the upper end of the regeneration tower 2 and moves downward in the regeneration tower 2. The regeneration tower 2 heats the adsorbent moving inside. Thereby, SOx is desorbed from the adsorbent and the adsorbent is regenerated. The regenerated adsorbent is discharged from the lower end of the regeneration tower 2. The adsorbent is sent to the adsorption tower 1 and supplied to the adsorption tower 1 again.

  The transfer devices 31 and 32 are used to transfer the adsorbent between the adsorption tower 1 and the regeneration tower 2. The adsorbent discharged from the lower end of the adsorption tower 1 is supplied to the transfer device 31. The transport device 31 transports the adsorbent toward the upper end of the regeneration tower 2. The adsorbent discharged from the lower end of the regeneration tower 2 is supplied to the transport device 32. The transport device 32 transports the adsorbent toward the upper end of the adsorption tower 1.

[Transport device]
Hereinafter, the configuration of the transport devices 31 and 32 will be described in detail. Since the configurations of the transport devices 31 and 32 are substantially the same, the transport devices 31 and 32 are not distinguished and are referred to as the transport device 3 unless particularly necessary.

  FIG. 2 is a schematic configuration diagram of the transport device 3. The transport device 3 transports the transported object along a predetermined transport route. The transported object of the transport device 3 according to the present embodiment is a granular adsorbent.

  As shown in FIG. 2, the transport device 3 includes a belt 301, a plurality of partitions 302, a guide tube 303, and a supply device 304. The transport device 3 further includes a driving pulley 305, a driven pulley 306, and a plurality of bend pulleys 307.

  The belt 301 is an endless flat belt. The belt 301 is stretched over a driving pulley 305 and a driven pulley 306. The driven pulley 306 is disposed below the drive pulley 305. The position of the driven pulley 306 in the horizontal direction is shifted from the position of the drive pulley 305 in the horizontal direction. That is, the driven pulley 306 is disposed obliquely below the driving pulley 305.

  Each of the driving pulley 305 and the driven pulley 306 has a rotation axis substantially parallel to the width direction of the belt 301. As the driving pulley 305 and the driven pulley 306 rotate around the rotation axis, the belt 301 runs. The belt 301 travels on a forward path R1 from the driven pulley 306 to the driving pulley 305 and a return path R2 from the driving pulley 305 to the driven pulley 306.

  In the forward path R1, a conveyed material is supplied to the belt 301, and a part of the belt 301 is deformed from a flat shape to a cylindrical shape. The conveyed material is wrapped in the cylindrical portion of the belt 301 and is conveyed upward along the outward route R1. In the present embodiment, the outward route R1 corresponds to a transport route of a transported object.

  The outward route R1 includes a vertical route R11 and curved roads R12 and R13. The vertical path R11 and the curved paths R12 and R13 constitute an ascending path for moving the conveyed material from below to above.

  The vertical path R11 extends substantially perpendicular to the horizontal plane. The curved path R12 is connected to the upper end of the vertical path R11, and extends further upward from the upper end of the vertical path R11. The curved path R12 has a generally upwardly convex arc shape. The curved path R13 extends from below the vertical path R11 toward the vertical path R11, and is connected to a lower end of the vertical path R11. The curved path R13 generally has a downwardly convex arc shape.

  The belt 301 traveling on the outward route R1 is turned back by the drive pulley 305 and travels on the return route R2. The belt 301 returns from a cylindrical shape to a flat shape near the driving pulley 305, and discharges the conveyed material. A plurality of bend pulleys 307 are arranged on the return path R2. The bend pulley 307 adjusts the traveling direction of the belt 301 on the return path R2. The belt 301 runs on the return path R2 downward from the drive pulley 305. The belt 301 turns back on the driven pulley 306 and travels on the outward route R1 again.

  As the material of the belt 301, for example, various materials used for a general conveyor belt, such as rubber, can be adopted. When the transport device 3 is used in the gas processing system 100 (FIG. 1), the material of the belt 301 is preferably one having flame retardancy or nonflammability.

  The plurality of partitions 302 are arranged in the traveling direction of the belt 301. The partition part 302 is fixed to one surface of the belt 301. More specifically, the partition portion 302 is fixed to a surface that is inside when the belt 301 is deformed into a cylindrical shape. The material of the partition 302 can be the same as the material of the belt 301.

  The guide tube 303 is arranged on the outward route R1. More specifically, the guide tube 303 is disposed on the vertical path R11 and the curved paths R12 and R13, which are the ascending paths. The guide tube 303 guides the belt 301 traveling on the outward route R1. As the guide tube 303, a known or commercially available pipe can be appropriately used. The guide tube 303 is preferably provided with a resin lining or the like on its inner surface in order to reduce frictional force.

  The guide tube 303 has a vertical portion 3031 and curved portions 3032 and 3033. Each of the vertical portion 3031 and the curved portions 3032 and 3033 has a cylindrical shape.

  The vertical portion 3031 is arranged on the vertical path R11. The vertical portion 3031 extends substantially perpendicular to the horizontal plane. The curved portions 3032 and 3033 are arranged on the curved paths R12 and R13, respectively. The curved portion 3032 is arranged above the vertical portion 3031. The curved portion 3032 has a generally upwardly convex arc shape. The curved portion 3033 is arranged below the vertical portion 3031. The curved portion 3033 has a generally downwardly convex arc shape. Each of the curved portions 3032 and 3033 has a plurality of gas injection ports 3034 and 3035.

  The supply device 304 is arranged on the outward route R1. The supply device 304 is arranged on the upstream side of the guide tube 303 in the running direction of the belt 301. The supply device 304 supplies the conveyed material to the belt 301. In the transfer device 31 (FIG. 1), the adsorbent discharged from the lower end of the adsorption tower 1 is supplied via a supply device 304. In the transfer device 32 (FIG. 1), the adsorbent discharged from the lower end of the regeneration tower 2 is supplied via a supply device 304.

  Hereinafter, each configuration of the transport device 3 will be described in more detail with reference to FIGS.

  FIG. 3 is a perspective view of a lower end portion of the transport device 3. FIG. 4 is a side view of the lower end portion of the transport device 3. First, with reference to FIG. 3, a plurality of partition portions 302 are fixed to one surface of belt 301 as described above. The partitions 302 are arranged along the running direction of the belt 301. The partition portions 302 are arranged at regular intervals over the entire length of the belt 301. The row of the partition portions 302 is formed at a central portion of the belt 301 in the width direction.

  Each of the partitions 302 is substantially disk-shaped. The partition part 302 includes a partition part main body 3021 and a rib 3022. The partition body 3021 has a shape in which a part of the outer peripheral side of the disk is cut off perpendicularly to the surface of the disk. Therefore, a part of the outer peripheral edge of the partition part main body 3021 is linear, and the remaining part is arc-shaped. A linear portion of the outer peripheral edge of the partition body 3021 is fixed to the belt 301. Both surfaces of the partition body 3021 are supported by ribs 3022, respectively. The rib 3022 is fixed to the partition body 3021. The rib 3022 is preferably not fixed to the belt 301. When the rib 3022 is fixed to the belt 301, when the belt 301 is wound around the driving pulley 305 or the driven pulley 306, the rib 3022 may be torn by stretching the outer peripheral surface of the belt 301 (the surface on which the partition 302 is provided). It is because there is.

  In the belt 301, a partition support portion 3011 is formed on a surface on which the partition portion 302 is provided. A plurality of partition support portions 3011 are provided corresponding to the partition portions 302, and are arranged along the running direction of the belt 301. The partition support portion 3011 supports the corresponding partition portion 302 when the belt 301 is deformed into a tubular shape.

  The partitioning support portion 3011 is, for example, a concave portion formed in the belt 301. In this case, when the belt 301 is wound around the rows of the partition portions 302 and deformed into a cylindrical shape, a part of the outer peripheral edge of the partition portion main body 3021 is accommodated in each partition support portion 3011. Thus, the partition 302 is maintained in a posture substantially perpendicular to the running direction of the belt 301. However, the configuration of the partition support 3011 is not limited to this. The partition support portion 3011 may be a convex portion on which a part of the partition portion 302 can be placed, a convex portion on which a part of the partition portion 302 can be sandwiched, or the like.

  At the lower end of the transport device 3, the belt 301 travels substantially horizontally on the return path R2. The portion of the belt 301 traveling on the return path R2 is kept flat. At the lower end of the transport device 3, the belt 301 travels on the return route R2 such that the surface on which the partition 302 is provided is on the lower side. The lower surface of the belt 301 is supported by a plurality of return rollers 309. The return rollers 309 are arranged in the running direction of the belt 301.

  After traveling on the return path R2, the belt 301 is turned back by the driven pulley 306 and travels on the outward path R1. The belt 301 is folded by the driven pulley 306, so that the belt 301 starts traveling on the outward path R1 with the surface on which the partition portion 302 is provided facing upward. A plurality of guide rollers 311, 312, 313, 314, 315 are arranged on the downstream side of the driven pulley 306 and on the upstream side of the guide tube 303 in the traveling direction of the belt 301.

  The guide rollers 311, 312, 313, 314 and 315 are arranged in this order from the upstream side to the downstream side in the running direction of the belt 301. The guide rollers 311, 312, 313, 314, and 315 guide the portion of the belt 301 that has started traveling on the outward path R <b> 1, and transform the belt 301 from a flat shape to a cylindrical shape. The belt 301 is deformed into a cylindrical shape along the outer periphery of the row of the partition portions 302. As described above, since the partition portion 302 has a substantially disk shape, the belt 301 is deformed into a substantially cylindrical shape.

  The guide roller 311 causes the belt 301 to start bending. The guide roller 311 passes the belt 301 while contacting the outer surface of the curved belt 301.

  The guide roller 312 bends the belt 301 curved by the guide roller 311 further deeply. The guide roller 312 passes the belt 301 while contacting the outer surface of the belt 301. The belt 301 is formed in a substantially U shape by passing through the guide roller 312.

  The guide rollers 313 and 314 maintain the shape of the belt 301 formed in a substantially U shape. The guide roller 313 passes the belt 301 while contacting the outer surface of the belt 301. The guide roller 314 passes the belt 301 while contacting the inner surface of the belt 301.

  The plurality of guide rollers 315 are annularly arranged along a plane perpendicular to the running direction of the belt 301. The plurality of guide rollers 315 allow the belt 301 to pass therethrough while contacting the outer surface of the belt 301, and deform the tube from a substantially U-shape to a cylindrical shape.

  While the belt 301 is deformed by the guide rollers 311, 312, 313, 314, and 315, a conveyed material is supplied from the supply device 304 to the belt 301. The supply device 304 is disposed between the guide roller 312 and the guide roller 314. The supply device 304 supplies the conveyed object to the curved portion 301a of the belt 301 that is curved in a substantially U shape by the guide rollers 312, 313, and 314.

  As illustrated in FIG. 3, the supply device 304 includes a charging unit 3041 and a regulating unit 3042. The regulating unit 3042 is connected to the lower end of the input unit 3041. Each of the charging section 3041 and the regulating section 3042 has a substantially cylindrical shape. In the present embodiment, the input section 3041 is in the shape of a rectangular tube whose axial direction is the vertical direction. The restricting portion 3042 is also a rectangular tube whose axis is in the vertical direction.

  The conveyed material is input from the input portion 3041, and is supplied to the curved portion 301a of the belt 301 via the restriction portion 3042. Conveyed objects can be continuously input from the input section 3041. The regulating unit 3042 regulates the passage of an extra conveyed material among the conveyed materials supplied to the curved portion 301a of the belt 301.

  Referring to FIG. 4, regulating portion 3042 includes a pair of side walls 3042a and 3042b. The pair of side walls 3042a are arranged substantially parallel to the running direction of the belt 301, and face each other. The pair of side walls 3042b are arranged substantially parallel to the width direction of the belt 301, and face each other.

  The restricting portion 3042 has an outer shape along the inner surface of the curved portion 301a of the belt 301 and the outer peripheral portion of the partition 302 exposed from the curved portion 301a. The side wall 3042a of the restricting portion 3042 is in contact with the inner surface of the substantially U-shaped curved portion 301a. The lower edge 3042c of the side wall 3042b is formed along the outer peripheral portion of the partition 302.

  The curved portion 301a is a portion of the belt 301 that curves along the outer periphery of the row of the partition portions 302 and is open at the upper side. A part of the outer peripheral edge of the partition body 3021 is exposed from the opening of the curved portion 301a. The lower edge 3042c of the side wall 3042b has a shape along the portion of the outer peripheral edge of the partition body 3021 that is exposed from the curved portion 301a. In the present embodiment, the lower edge 3042c has an arc shape.

  It is preferable that the gap between the restriction portion 3042 and the partition portion 302 is set to a size that prevents passage of the transported object. For example, in the direction perpendicular to the running direction and the width direction of the belt 301 (in the vertical direction in the present embodiment), the maximum distance from the lower edge 3042c to the partition body 3021 is preferably set to 3 times the average particle diameter of the conveyed material. It can be less than 1-fold, more preferably less than 1-fold.

  The conveyed material is supplied from the supply device 304 to the curved portion 301a of the belt 301, and is sent downstream. When the conveyed material is supplied to the curved portion 301a to a height exceeding the lower edge 3042c of the side wall portion 3042b, the conveyed material exceeding the lower edge 3042c is prevented from moving downstream by the side wall portion 3042b. Therefore, the belt 301 runs in a state where an appropriate amount of the conveyed material is supplied between the partition portions 302 on the belt 301.

  Referring again to FIG. 3, the curved portion 301 a of the belt 301 is changed into a tubular portion by the guide roller 315. The cylindrical portion of the belt 301 is introduced into the curved portion 3033 of the guide tube 303. Gas is injected into the curved portion 3033 from a gas injection port 3035. This gas is, for example, an inert gas such as nitrogen. The cylindrical portion travels on a rising path along the guide tube 303.

  FIG. 5 is an enlarged view of a part of the ascending path of the transport device 3. As shown in FIG. 5, the internal space of the cylindrical portion 301b of the belt 301 is divided into a plurality of sections along the running direction of the belt 301. A plurality of spaces S separated by a partition 302 are formed in the cylindrical portion 301b of the belt 301.

  Each space S contains a transported object (not shown). Although not particularly limited, the filling rate of the conveyed material in the space S is preferably about 80%. The transported object in each space S is placed on the placement surface 302a of the partition 302. The mounting surface 302a is provided on the main surface of the disk-shaped partition 302. Of the two surfaces of the partition portion 302, a surface arranged on the downstream side in the running direction of the belt 301 is defined as a main surface, and a surface arranged on the upstream side is defined as a back surface. In other words, in the cylindrical portion 301b traveling on the vertical road R11, the upper surface of the partition portion 302 becomes the main surface. In the present embodiment, the mounting surface 302a is a substantially circular surface.

  Each mounting surface 302a is not divided. That is, each mounting surface 302a is not a set of a plurality of surfaces but a single surface. The area of each mounting surface 302a is substantially equal to the cross-sectional area of the cylindrical portion 301b (space S) of the belt 301. However, there may be a gap between the mounting surface 302a and the cylindrical portion 301b to such an extent that the conveyed material does not substantially pass. The gap between the mounting surface 302a and the cylindrical portion 301b can be, for example, preferably less than three times, more preferably less than one time, the average particle diameter of the conveyed material.

  FIG. 6 is a perspective view of the upper end of the transport device 3. As shown in FIG. 6, a portion of the belt 301 that travels on the ascending route and is discharged from the curved portion 3032 of the guide tube 303 is deformed from a cylindrical shape to a flat shape. A plurality of guide rollers 316 are arranged downstream of the guide tube 303 in the running direction of the belt 301. The guide roller 316 guides the belt 301 so that the belt 301 is gently deformed from a cylindrical shape to a flat shape. Note that, similarly to the bending portion 3033, an inert gas such as nitrogen is injected into the bending portion 3032 from the gas injection port 3034.

  At the upper end of the transport device 3, the belt 301 that has returned to the flat shape is turned back by the drive pulley 305 and travels on the return path R2. The belt 301 travels on the return route R2 such that the surface on which the partition portion 302 is provided is on the lower side. The lower surface of the belt 301 is supported by a plurality of return rollers 309, similarly to the lower end of the transport device 3.

[effect]
In the transport device 3 according to the first embodiment, the belt 301 deforms along the outer periphery of the row of the partition portions 302 when traveling on the ascending route, and forms a cylindrical portion 301b. In the cylindrical portion 301b, a conveyed object is placed on the placement surface 302a of each partition 302. The transported object in the first embodiment is a granular adsorbent, but since each mounting surface 302a is not divided, the transported object does not bite. Therefore, it is possible to prevent the transported object from falling during the transport.

  For example, in a general cylindrical conveyor, when the running direction of a cylindrically deformed belt is changed from a horizontal direction to a vertical direction or from a vertical direction to a horizontal direction, the belt is bent in a cylindrically deformed state. At the bent portion of the belt, the tension acting on the belt on the outer peripheral side becomes larger than on the inner peripheral side. For this reason, the belt may be shifted toward the inner peripheral side, and the cross section of the cylindrical portion of the belt may be crushed, the belt may be twisted, or the belt may rotate. These phenomena are particularly likely to occur when there is no conveyed article in the belt or when the amount of conveyed article in the belt is small. Normally, by increasing the radius of curvature of the bent portion, it is possible to prevent the cross section of the belt from being crushed.

  On the other hand, in the transport device 3 according to the first embodiment, when the belt 301 is deformed into a tubular shape, the belt 301 is wound around a row of the partition portions 302 fixed to the belt 301. By the rows of the partition portions 302, the shape of the belt 301 can be maintained in a cylindrical shape even when the amount of the conveyed material in the belt 301 is insufficient. For this reason, even in the curved roads R12 and R13 that change the traveling direction of the belt 301, the cylindrical cross section of the belt 301 is not easily crushed. Therefore, the curvature radii of the curved paths R12 and R13 can be reduced, and the entire transport device 3 can be made compact. In addition, since the cylindrical cross section of the belt 301 is not easily crushed, it is possible to prevent the conveyed material from falling off the belt 301.

  In the first embodiment, in the cylindrical portion 301b of the belt 301, each partition 302 is supported by a corresponding partition support 3011. Therefore, it is possible to prevent the partition portion 302 from hanging down due to the weight of the transported object and the like, and the space S in the cylindrical portion 301b from collapsing. As a result, falling of the transported object in the cylindrical portion 301b is suppressed, and the transported object can be transported stably.

  In the transport device 3 according to the first embodiment, the supply unit 304 that supplies the transported material to the belt 301 is provided with a regulating unit 3042. The outer shape of the restriction portion 3042 is formed along the outer peripheral portion of the partition portion 302. More specifically, the lower edge 3042c of the side wall 3042b of the restricting portion 3042 has an arc shape along the outer peripheral portion of the partition portion 302. With such a configuration, when an amount of the conveyed material exceeding the lower edge 3042c of the side wall portion 3042b is supplied to the curved portion 301a in the running direction of the belt 301, the conveyed material exceeds the lower edge 3042c. Can be dammed by the side wall portion 3042b. Therefore, it is possible to prevent the amount of the conveyed material substantially protruding from the partitioning portion 302 from being supplied to the space between the partitioning portions 302 when viewed in the traveling direction of the belt 301. It can be provided between the parts 302.

  In the first embodiment, the side wall 3042a of the regulating portion 3042 is inscribed in the curved portion 301a. For this reason, it is possible to prevent the conveyed material from spilling out of the belt 301 when the conveyed material is supplied from the supply device 304 to the belt 301. Further, dust generation around the supply device 304 can be suppressed.

  In the first embodiment, the main surface of the disk-shaped partition portion 302 functions as a mounting surface 302a on which a conveyed object is mounted. With the mounting surface 302a, the transported object can be stably held, and the fall of the transported object during the transport can be suppressed more reliably.

  In a general finned belt, since fins are provided over the entire width of the belt, it is difficult to apply a belt cleaner, and it is difficult to remove deposits on the belt. On the other hand, in the first embodiment, the partition portion 302 is provided only at the central portion in the width direction of the belt 301. Therefore, the deposits on the belt 301 can be easily removed by the belt cleaner.

  In the first embodiment, the cylindrical portion 301b of the belt 301 runs in the guide tube 303. Thereby, it is possible to prevent the cylindrical portion 301b from opening and the conveyed object from falling. In addition, since the shape of the cylindrical portion 301b can be maintained by the guide tube 303, it is not necessary to provide a roller for maintaining the shape, a driving mechanism thereof, and the like in the transport device 3. Therefore, the configuration of the transport device 3 can be simplified.

  In the first embodiment, a gas such as nitrogen is injected into the curved portions 3032 and 3033 of the guide tube 303 while the belt 301 is running. Thereby, the frictional resistance of the inner surfaces of the curved portions 3032 and 3033 can be reduced.

<Second embodiment>
FIG. 7 is a diagram illustrating a schematic configuration of a transport device 3A according to the second embodiment. The transfer device 3A can be used in the gas processing system 100 (FIG. 1) described in the first embodiment. The transport device 3A differs from the transport device 3 according to the first embodiment mainly in the arrangement and configuration of the supply device 304A.

  As shown in FIG. 7, in the transport device 3A, the supply device 304A is provided on the ascending path. More specifically, the supply device 304A is disposed on the vertical path R11 of the ascending path. In the transport device 3A, a guide tube 303A having a configuration different from that of the guide tube 303 (FIG. 2) of the first embodiment is used by disposing the supply device 304A on the vertical path R11.

  The guide tube 303A passes through the cylindrical portion of the belt 301. The guide tube 303A has vertical portions 3031Aa and 3031Ab, and a curved portion 3032. The vertical portion 3031Aa is arranged above the supply device 304A. The vertical portion 3031Ab is disposed below the supply device 304A. The cylindrical portion of the belt 301 is opened when traveling between the vertical portions 3031Aa and 3031Ab, and changes to a curved portion. That is, in the cylindrical portion that runs between the vertical portions 3031Aa and 3031Ab, the overlapping side edges are separated from each other, exposing the partition portion 302.

  FIG. 8 is an enlarged view showing a peripheral portion of the supply device 304A in the transport device 3A shown in FIG. As shown in FIG. 8, the supply device 304A includes a charging unit 3041A and a regulating unit 3042A.

  The restricting portion 3042A is provided so as to be located inside the belt 301 wound around the row of the partition portions 302. The restricting portion 3042A extends vertically across the plurality of partition portions 302. The restricting portion 3042A has a shape along the outer periphery of the partition portion 302. In the present embodiment, the cross section of the restricting portion 3042A has an arc shape.

  The input section 3041A is connected to the regulating section 3042A. The input section 3041A extends obliquely upward from an intermediate position in the vertical direction of the regulating section 3042A. The upper end of the input section 3041A is arranged outside the belt 301. The input section 3041A has a tubular shape and communicates with the inside of the curved portion of the belt 301. The conveyed material is input from the upper end opening of the input portion 3041A, moves by its own weight, and is supplied to the curved portion of the belt 301. In this way, the conveyed material is supplied to the space S formed between the adjacent partitions 302 of the belt 301.

  Also in the transport device 3A according to the second embodiment, a substantially constant and appropriate amount of transported material can be supplied between the partition portions 302. The supply amount of the conveyed product is regulated by the regulation section 3042A of the supply device 304A. In other words, even if a large amount of conveyed material is input from the input section 3041A, since the regulating section 3042A has a shape along the outer circumference of the partition section 23, the amount protruding between the partition sections 302 toward the outer peripheral side of the partition section 302. Is not supplied. Therefore, the conveyed material is quantitatively supplied to the space S between the partition portions 302 by the regulating portion 3042A.

  In the transport device 3 according to the first embodiment, a horizontal path for installing the supply device 304 is provided at the lower end of the transport device 3. On the other hand, in the transport apparatus 3A according to the second embodiment, the horizontal path at the lower end becomes unnecessary because the feeder 304A is installed on the ascending path. Therefore, according to the second embodiment, the planar layout of the transport device 3A can be made compact.

<Third embodiment>
FIG. 9 is a diagram illustrating a schematic configuration of a transport device 3B according to the third embodiment. The transfer device 3B can be used in the gas processing system 100 (FIG. 1) described in the first embodiment. The transport device 3B has the same configuration as the transport device 3A according to the second embodiment except for the configuration in the return path R2.

  As shown in FIG. 9, in the transport device 3B, the belt 301 is deformed from a cylindrical shape to a flat shape at the upper end of the outward path R1, and is folded back by the driving pulley 305. Thereafter, the belt 301 deforms from a flat shape to a tubular shape and travels on the return path R2. The belt 301 is deformed from a cylindrical shape to a flat shape near the driven pulley 306.

  In the present embodiment, unlike the first and second embodiments, a portion of the belt 301 that travels on the return path R2 is formed in a cylindrical shape. Therefore, a guide tube 303B is also provided in the return path R2. The guide tube 303B has a vertical portion 3031B and a curved portion 3032B. The vertical portion 3031B is not divided unlike the vertical portions 3031Aa and 3031Ab of the guide tube 303A in the outward path R1. In the return path R2, the cylindrical portion of the belt 301 runs in the curved portion 3032B and the vertical portion 3031B.

  The embodiment according to the present disclosure has been described above, but the present disclosure is not limited to the above embodiment, and various changes can be made without departing from the gist of the present disclosure.

  In each of the above embodiments, the partition 302 is formed in a disk shape. However, the shape of the partition 302 is not limited to this. The partition 302 may have a plate shape having a polygonal surface, or may not have a plate shape (flat shape).

  In each of the above embodiments, in the guide tubes 303, 303A, and 303B, the curved portion 3032 located above the outward path R1 is formed of a single tube member. However, as shown in FIG. 10, the curved portion 3032C of the guide tube may be configured by a plurality of tube members 3032Ca. The tube members 3032Ca are arranged with a space therebetween. According to this configuration, it is not necessary to provide a roller for maintaining the shape of the belt 301 on the entire curved path, and a roller may be provided only between the pipe members 3032Ca. Therefore, the transport device can be simplified.

  Although not shown, in the guide tube 303 of the first embodiment, the curved portion 3033 provided at the lower part of the outward path R1 can also be constituted by a plurality of tube members.

  The transport devices 3, 3A, 3B, and 3C according to the above embodiments transport the transported material in the vertical direction, but the transport direction of the transported material is not limited to this. For example, a conveyed article can be conveyed obliquely upward. That is, the ascending path included in the transport path may be provided with the vertical path R11 as in each of the above embodiments, or may be provided with an inclined path from below to above instead of the vertical path R11. Is also good. The curved paths R12 and R13 can be excluded from the ascending path as necessary.

  In the above embodiments, the transport devices 3, 3A, 3B are used in the gas processing system 100. However, the transport device according to the present disclosure can be used in any equipment where upward transport of a transported object occurs. The transport device according to the present disclosure is particularly suitable for transporting bulk materials.
