Description

ブラスト装置、及び船舶Blast equipment and ships
　本発明は、ブラスト装置、及び船舶に関する。 The present invention relates to a blasting device and a ship.
　従来のブラスト装置として、特許文献１に記載されたものが知られている。このブラスト装置は、船舶の外板などの対象物に対して研磨剤を投射することで、対象物を研磨する。また、このブラスト装置は、研磨作業で発生した粉塵を集塵回収している。 As a conventional blasting device, the one described in Patent Document 1 is known. This blasting device polishes an object such as the outer plate of a ship by projecting an abrasive onto the object. In addition, this blasting device collects and collects dust generated during the polishing work.
実用新案出願公開昭５８－１０８９９８号公報Utility Model Application Publication No. 58-108998
　ここで、上記従来技術による研磨剤の他、船の外板に塗料を張り付けやすくするための研掃材を投射するものもある。研掃材により、外板の表面積が上がり、その分塗装も張り付きやすくなる。この反面、投射後の研掃材は、湿気やごみが付着する（湿気やごみが付着すると錆の原因となる）のでそのまま廃棄されていた。 Here, in addition to the above conventional abrasives, there are also methods that project an abrasive to make it easier to apply paint to the outer plate of the ship. Abrasives increase the surface area of the outer panel, making it easier for paint to stick to it. On the other hand, the abrasive material after being projected has been discarded as it is because it is attached with moisture and dust (attachment of moisture and dust causes rust).
　そこで、本発明は、研掃材の使用量を低減すると共に、作業効率を向上できるブラスト装置、及び船舶を提供することを目的とする。 Therefore, an object of the present invention is to provide a blasting device and a vessel that can reduce the amount of abrasives used and improve work efficiency.
　本発明に係るブラスト装置は、研掃材を対象物へ投射する船舶のブラスト装置であって、研掃材を投射する投射部と、投射した研掃材を回収する回収部と、を備え、回収部は、投射部による研掃材の投射をしながら、研掃材を回収可能である。 A blasting device according to the present invention is a ship blasting device for projecting an abrasive material onto an object, comprising a projection unit for projecting the abrasive material and a collecting unit for collecting the projected abrasive material, The collecting section can collect the abrasive while projecting the abrasive by the projecting section.
　ブラスト装置は、研掃材を投射する投射部と、投射した研掃材を回収する回収部と、を備える。このように、ブラスト装置が回収部を備えることで、ブラスト装置は、一度対象物へ投射した研掃材を回収部で回収することで、廃棄することなく、再度使用することができる。また、回収部は、投射部による研掃材の投射をしながら、研掃材を回収可能である。従って、ブラスト装置は、投射部での投射の作業を停止することなく、投射後の研掃材に湿気やごみが付着する前に、回収部にて研掃材の回収作業を行うことができる。以上より、研掃材の使用量を低減すると共に、作業効率を向上できる。 The blasting device includes a projection section that projects the abrasive and a collection section that collects the projected abrasive. In this way, the blasting apparatus is provided with the collecting section, and the blasting apparatus collects the abrasive once projected onto the object by the collecting section, so that the abrasive can be reused without being discarded. Further, the collecting section can collect the abrasive while projecting the abrasive by the projecting section. Therefore, the blasting apparatus can recover the abrasive in the recovering section without stopping the blasting operation in the blasting section and before moisture or dust adheres to the abrasive after blasting. . As described above, it is possible to reduce the usage amount of the abrasive and improve the working efficiency.
　回収部は、投射部で投射対象に当たって落下した研掃材を回収してよい。これにより、回収部は、投射部が研掃材の投射を行っている一方で、投射対象の下方に貯まった状態の研掃材を回収できる。 The collection unit may collect the abrasive that has fallen after hitting the projection target in the projection unit. As a result, while the projection unit is projecting the abrasive, the recovery unit can recover the abrasive accumulated below the projection target.
　回収部で回収した研掃材を投射部にて再利用してよい。これにより、研掃材の使用量を低減できる。 The abrasive material collected in the collection unit may be reused in the projection unit. As a result, the amount of abrasive used can be reduced.
　投射部と回収部は、一つのカーゴタンク内で投射及び回収を行ってよい。例えば、投射部及び回収部を複数のカーゴタンクに設ける場合（例えば、投射部をあるカーゴタンクに設け、回収部を別のカーゴタンクに設ける場合）、それぞれのカーゴタンクの容量が異なると、回収する研掃材の量と投射する研掃材の量がばらばらになり、回収して投射する研掃材が足りなくなる可能性がある。これに対し、投射部と回収部が、一つのカーゴタンク内で投射及び回収を行う場合、回収して投射する研掃材が足りなくなることを抑制できる。 The projection part and recovery part may perform projection and recovery in one cargo tank. For example, when the projection unit and the recovery unit are provided in a plurality of cargo tanks (for example, when the projection unit is provided in one cargo tank and the recovery unit is provided in another cargo tank), if the cargo tanks have different capacities, the recovery The amount of abrasive to be applied and the amount of abrasive to be projected will be different, and there is a possibility that the amount of abrasive to be collected and projected will be insufficient. On the other hand, when the projecting section and the collecting section perform projecting and collecting within one cargo tank, it is possible to prevent the shortage of the abrasive material to be collected and projected.
　回収部は、粉塵及び研掃材を回収するモードと、粉塵のみを回収するモードと、を有してよい。この場合、回収部は状況に応じてモードの切替を行うことができる。 The collection unit may have a mode for collecting dust and abrasives and a mode for collecting only dust. In this case, the recovery unit can switch modes depending on the situation.

The cleaning material that falls and accumulates in the storage section may be stored as the cleaning material to be re-projected by the projection section. The collection line can transmit the suction force generated by the suction section to the collection section, and can function as a transfer path for transferring the abrasive material collected by the collection section to the storage section.
　回収部で回収された粉塵は、吸引部によって貯蔵部に吸引され、当該貯蔵部内から更に吸引部へ吸引されてよい。この場合、貯蔵部において、研掃材と粉塵を分離することができる。 The dust collected by the collection unit may be sucked into the storage unit by the suction unit, and further sucked into the suction unit from within the storage unit. In this case, the abrasive and dust can be separated in the reservoir.
　ブラスト装置は、投射部で投射する研掃材の不足分を補給する補給部を更に備えてよい。この場合、研掃材が不足した場合に、補給部が研掃材を補給することができる。 The blasting device may further include a replenishment section that replenishes the shortage of the abrasive material projected by the projection section. In this case, when the abrasive is insufficient, the replenishing section can replenish the abrasive.

In this embodiment, the projection unit 2 has two injection devices 11, and each injection device 11 has two sets of blast hoses 13 and blast nozzles 15, but the number is not particularly limited.
　回収部３は、投射した研掃材を回収する装置である。回収部３は、投射部２で投射対象に当たって落下した研掃材を回収する。回収部３は、ラインＬ１，Ｌ２を介して、研掃材を吸引する吸引部４と接続される。従って、回収部３は、吸引部４からの吸引力によって、研掃材を回収する。回収部３は、ヘッダ１４と、床ブラシ１６と、回収用ホース１７と、を備える。ヘッダ１４は、ラインＬ１と複数本の回収用ホース１７とを接続する継手である。ヘッダ１４は、船舶１００の甲板１０１上に設けられる。ヘッダ１４は、水平方向に延びるパイプ状の部材であり、長手方向において所定間隔で、回収用ホース１７を接続する接続部１４ａを有する。接続部１４ａに接続された回収用ホース１７は、船舶１００の内部へ延びている。回収用ホース１７は、床ブラシ１６にて吸引された研掃材をヘッダ１４へ移送するホースである。回収用ホース１７の先端には、床ブラシ１６が設けられている。床ブラシ１６は、対象物へ投射された後の研掃材を掃きながら回収する器具である。作業者は、床ブラシ１６を保持して、船舶１００の所望の箇所にて研掃材を掃きながら吸引することができる。なお、床ブラシ１６は、走行台車などに設けられてもよく、この場合は、床ブラシ１６が走行台車の移動に伴って、研掃材を回収しながら移動する。 The recovery unit 3 is a device that recovers the projected abrasive. The recovery unit 3 recovers the abrasive that has fallen after hitting the projection target in the projection unit 2 . The collection unit 3 is connected to a suction unit 4 for sucking the abrasive through lines L1 and L2. Therefore, the recovery section 3 recovers the abrasive by the suction force from the suction section 4 . The recovery section 3 includes a header 14 , a floor brush 16 and a recovery hose 17 . The header 14 is a joint that connects the line L<b>1 and a plurality of recovery hoses 17 . Header 14 is provided on deck 101 of ship 100 . The header 14 is a pipe-shaped member extending in the horizontal direction, and has connection portions 14a for connecting the recovery hose 17 at predetermined intervals in the longitudinal direction.

　なお、ヘッダ１４の先端部には、補給口１４ｂが設けられている。補給口１４ｂには、図示されないホースが接続され、船舶１００外の岸壁などに設置された研掃材ボックスなどから、補給用の研掃材を吸引することができる。例えば、床ブラシ１６から船舶１００内の研掃材の回収が不能となった場合などに、補給口１４ｂは、緊急対応として船舶１００外の研掃材を吸引してよい。 A replenishment port 14b is provided at the tip of the header 14. A hose (not shown) is connected to the replenishment port 14b, and a replenishment abrasive can be sucked from an abrasive box installed on a quay outside the ship 100 or the like. For example, when it becomes impossible to collect the abrasive inside the vessel 100 from the floor brush 16, the supply port 14b may suck the abrasive outside the vessel 100 as an emergency measure.
　吸引部４は、回収部３にて研掃材を吸引するための吸引力を発生する装置である。吸引部４は、船舶１００の甲板１０１上に設けられる。例えば、吸引部４は、内部を真空状態として吸引力を発生する真空回収機１８を備えている。本実施形態では、吸引部４は二台の真空回収機１８を備えているが、数量は特に限定されない。吸引部４は、ラインＬ２、貯蔵部６の内部空間、及びラインＬ１を介して、回収部３のヘッダ１４と連通している。すなわち、吸引部４で発生した吸引力は、回収部３のヘッダ１４へ伝達され、更に回収用ホース１７を介して床ブラシ１６に伝達される。このような構成により、ラインＬ２、及びラインＬ１は、船舶１００内の研掃材、及びそこに含まれる粉塵などを回収するための回収ラインＬ１０として構成される。 The suction unit 4 is a device that generates a suction force for sucking the abrasive material in the recovery unit 3 .

The suction unit 4 communicates with the header 14 of the recovery unit 3 via the line L2, the internal space of the storage unit 6, and the line L1. That is, the suction force generated by the suction unit 4 is transmitted to the header 14 of the collection unit 3 and further transmitted to the floor brush 16 via the collection hose 17 . With such a configuration, the line L2 and the line L1 are configured as a recovery line L10 for recovering the abrasive material in the ship 100 and the dust contained therein.
　貯蔵部６は、研掃材を貯めておく装置である。貯蔵部６は、内部空間に研掃材を貯めておくコレクトタンクによって構成される。また、貯蔵部６は、回収ラインＬ１０の中途位置に設けられる。すなわち、貯蔵部６は、ラインＬ１とラインＬ２との間に設けられる。ラインＬ１及びラインＬ２は、貯蔵部６の上端部６ｂに設けられる。ラインＬ１及びラインＬ２には、貯蔵部６の上端部６ｂ付近に補給用ダンパ２１が設けられる。なお、ブラスト装置１の運転開始時には、貯蔵部６の上蓋が開けられて、新しい研掃材が供給される。 The storage unit 6 is a device that stores abrasives. The storage unit 6 is composed of a collection tank in which the abrasive is stored in its internal space. In addition, the storage unit 6 is provided at an intermediate position of the recovery line L10. That is, the storage section 6 is provided between the line L1 and the line L2. The line L1 and the line L2 are provided at the upper end portion 6b of the reservoir 6. As shown in FIG. A supply damper 21 is provided in the vicinity of the upper end portion 6b of the storage portion 6 on the lines L1 and L2. When the blasting apparatus 1 starts operating, the upper lid of the storage section 6 is opened and new abrasive is supplied.
　貯蔵部６は、船舶１００の甲板１０１から上方へ離間した位置であって、投射部２の噴射装置１１の上側に設けられる。貯蔵部６の下端側には、内部空間に貯められた研掃材を集めるホッパ６ａが設けられる。また、ホッパ６ａは、研掃材を各噴射装置１１に分配するための分配部２２を介して、各噴射装置１１に接続される。分配部２２は、ホッパ６ａの底部の一つの開口部から延びる一本の流路が、二本の流路に分岐する構成を有する。また、分配部２２の各流路と各噴射装置１１とは、供給用ダンパ２３を介して接続されている。貯蔵部６は、フレーム２５に支持されており、噴射装置１１はフレーム２５の内部に配置されている。このように、貯蔵部６と噴射装置１１は、一体的なユニットとしてコンパクトに構成される。 The storage section 6 is located above the deck 101 of the ship 100 and is provided above the injection device 11 of the projection section 2 . A hopper 6a for collecting the abrasive stored in the internal space is provided at the lower end side of the storage section 6. As shown in FIG. The hopper 6 a is also connected to each injection device 11 via a distribution section 22 for distributing the abrasive material to each injection device 11 . The distribution part 22 has a structure in which one channel extending from one opening in the bottom of the hopper 6a branches into two channels. Further, each channel of the distribution section 22 and each injection device 11 are connected via a supply damper 23 . The reservoir 6 is supported by a frame 25 and the injection device 11 is arranged inside the frame 25 . Thus, the reservoir 6 and the injection device 11 are compactly constructed as an integral unit.
　ここで、貯蔵部６内に貯められた研掃材の界面を「Ｆ」とする。この場合、界面Ｆと上端部６ｂとの間には空間ＳＰが形成される。回収部３で回収された研掃材は、ラインＬ１を介して、貯蔵部６の空間ＳＰ内へ供給される。このとき、所定の大きさの研掃材の粒は、空間ＳＰ内を落下して、界面Ｆ上に堆積する。その一方、小さくなった粒は、ラインＬ２からの吸引力によって、粉塵としてラインＬ２に吸引される。このように、吸引部４で吸引された研掃材のうち、貯蔵部６内に落下して堆積するものが、投射部２にて再投射される研掃材として貯蔵される。その一方、回収部３が回収した粉塵は、吸引部４によって貯蔵部６に吸引され、当該貯蔵部６内から更に吸引部４へ吸引される。なお、１０６μｍ以下の粒が、粉塵としてラインＬ２へ吸引され、それより大きい粒が研掃材として界面Ｆに堆積する。このときの吸引部４で発生する吸引力に関し、真空回収機の出力が７５ｋｗに設定され、真空圧が－６０ｋｐａに設定され、最大風量が４５ｍ２／ｍｉｎに設定されてよい。 Here, the interface of the abrasive stored in the storage section 6 is defined as "F". In this case, a space SP is formed between the interface F and the upper end portion 6b. The abrasive collected by the collection unit 3 is supplied into the space SP of the storage unit 6 via the line L1. At this time, particles of the abrasive having a predetermined size fall within the space SP and deposit on the interface F. On the other hand, the grains that have become smaller are sucked into the line L2 as dust by the suction force from the line L2. In this way, of the abrasive sucked by the suction unit 4 , the abrasive that falls and accumulates in the storage unit 6 is stored as the abrasive to be re-projected by the projection unit 2 . On the other hand, the dust collected by the collection unit 3 is sucked into the storage unit 6 by the suction unit 4 and further sucked from the inside of the storage unit 6 to the suction unit 4 . Particles of 106 μm or less are sucked into the line L2 as dust, and larger particles are deposited on the interface F as the abrasive. Regarding the suction force generated by the suction unit 4 at this time, the output of the vacuum collector may be set at 75 kw, the vacuum pressure may be set at -60 kpa, and the maximum air volume may be set at 45 m2/min.
　上述の様に、吸引部４が回収ラインＬ１０を介して回収部３の吸引力を発生させる動作と、投射部２が貯蔵部６から供給される研掃材を噴射する動作とは、互いに独立した関係にある。すなわち、回収部３は、投射部２が投射を行っているか否かに関わらず、研掃材の回収を行うことができる。従って、回収部３は、投射部２による研掃材の投射をしながら、研掃材を回収することができる。 As described above, the operation of the suction unit 4 generating the suction force of the recovery unit 3 via the recovery line L10 and the operation of the projection unit 2 ejecting the abrasive supplied from the storage unit 6 are independent of each other. have a relationship. That is, the recovery unit 3 can recover the abrasive regardless of whether or not the projection unit 2 is projecting. Therefore, the recovery unit 3 can recover the abrasive while the projection unit 2 is projecting the abrasive.
　補給部７は、投射部２で投射する研掃材の不足分を補給する装置である。補給部７は、研掃材を貯留するタンク３１と、タンク３１とラインＬ１を接続するラインＬ３に設けられた補給用ダンパ３２と、を備える。補給部７は、貯蔵部６での研掃材が不足している場合に、補給用ダンパ３２を開とする。これにより、タンク３１の研掃材は、タンク３１からラインＬ１へ落下し、吸引されて貯蔵部６へ供給される。 The replenishing unit 7 is a device that replenishes the shortage of the abrasive material projected by the projecting unit 2 . The replenishment unit 7 includes a tank 31 for storing abrasive material, and a replenishment damper 32 provided in a line L3 connecting the tank 31 and the line L1. The supply unit 7 opens the supply damper 32 when the abrasive material in the storage unit 6 is insufficient. As a result, the abrasive in the tank 31 drops from the tank 31 to the line L<b>1 , is sucked, and is supplied to the storage section 6 .
　ラインＬ１とラインＬ２とを接続するバイパスラインＬ４には、バイパス用ダンパ３３が設けられる。 A bypass damper 33 is provided on the bypass line L4 that connects the line L1 and the line L2.
　次に、ブラスト装置１の動作について説明する。図１内において示される矢印は、回収部３にて回収された研掃材、及び粉塵の流れを示している。一方、図２内において示される矢印は、粉塵の回収のみを行う場合の粉塵の流れを示している。このように、回収部３は、粉塵及び研掃材を回収するモードと、粉塵のみを回収するモードと、を有する。 Next, the operation of the blasting device 1 will be explained. The arrows shown in FIG. 1 indicate the flow of the abrasive and dust collected by the collecting unit 3 . On the other hand, the arrows shown in FIG. 2 indicate the flow of dust when dust is only collected. In this manner, the collecting section 3 has a mode for collecting dust and abrasive material and a mode for collecting only dust.
　図１に示すように、回収部３にて研掃材の回収を行う際には、補給用ダンパ２１、及び供給用ダンパ２３を開とし、補給用ダンパ３２及びバイパス用ダンパ３３を閉とする。また、投射部２の噴射装置、及び吸引部４の真空回収機１８を起動させる。これにより、投射部２のブラストノズル１２から研掃材の投射が行われる。また、回収部３の床ブラシ１６が船舶１００内の研掃材を吸引して回収する。 As shown in FIG. 1, when collecting the abrasive material in the collecting section 3, the supply damper 21 and the supply damper 23 are opened, and the supply damper 32 and the bypass damper 33 are closed. . Also, the injection device of the projection unit 2 and the vacuum collector 18 of the suction unit 4 are activated. As a result, the abrasive material is projected from the blast nozzle 12 of the projection unit 2 . Also, the floor brush 16 of the recovery unit 3 sucks and recovers the abrasive in the ship 100 .
　回収部３で回収された研掃材及び粉塵は、ラインＬ１を介して貯蔵部６へ供給される。研掃材は、貯蔵部６の上端部６ｂから空間ＳＰで落下し、界面Ｆに堆積する。一方、粉塵は、貯蔵部６から更にラインＬ２を介して吸引部４まで吸引される。これにより、投射後の研掃材は貯蔵部６に再び貯蔵され、粉塵は真空回収機１８に回収される。循環する研掃材が不足していることが検知された場合、補給部７は補給用ダンパ３２を開として、タンク３１内の新しい研掃材をラインＬ１へ落下させる。ラインＬ１に落下した新しい研掃材は、貯蔵部６へ吸引されると共に、落下して界面Ｆに堆積する。 The abrasive and dust collected by the collection unit 3 are supplied to the storage unit 6 via the line L1. The abrasive drops from the upper end portion 6b of the storage portion 6 in the space SP and deposits on the interface F. As shown in FIG. On the other hand, the dust is sucked from the storage section 6 to the suction section 4 through the line L2. As a result, the abrasive after being projected is stored again in the storage unit 6 and the dust is recovered by the vacuum recovery device 18 . When it is detected that the circulating abrasive is insufficient, the supply section 7 opens the supply damper 32 to drop new abrasive in the tank 31 into the line L1. The new abrasive that has fallen into the line L1 is sucked into the storage section 6, drops down, and deposits on the interface F. As shown in FIG.
　図２に示すように、回収部３にて粉塵の回収のみを行う際には、補給用ダンパ２１、供給用ダンパ２３、及び補給用ダンパ３２を閉とし、バイパス用ダンパ３３を開とする。また、吸引部４の真空回収機１８を起動させる。これにより、回収部３の床ブラシ１６が船舶１００内の粉塵を吸引して回収する。そして、回収部３で回収された粉塵は、ラインＬ１を通過すると共に、バイパスラインＬ４を通過してラインＬ２へバイパスされ、吸引部４の真空回収機１８にて回収される。 As shown in FIG. 2, when only dust is collected by the collection unit 3, the replenishment damper 21, the supply damper 23, and the replenishment damper 32 are closed, and the bypass damper 33 is opened. Also, the vacuum collector 18 of the suction unit 4 is activated. As a result, the floor brush 16 of the collecting unit 3 sucks and collects the dust inside the ship 100 . The dust collected by the collection unit 3 passes through the line L1 and the bypass line L4 to the line L2 and is collected by the vacuum collector 18 of the suction unit 4 .
　次に、本実施形態に係るブラスト装置１、及び船舶１００の作用・効果について説明する。 Next, the actions and effects of the blasting device 1 and the ship 100 according to this embodiment will be described.
　ブラスト装置１は、研掃材を投射する投射部２と、投射した研掃材を回収する回収部３と、を備える。このように、ブラスト装置１が回収部３を備えることで、ブラスト装置１は、一度対象物へ投射した研掃材を回収部３で回収することで、廃棄することなく、再度使用することができる。また、回収部３は、投射部２による研掃材の投射をしながら、研掃材を回収可能である。従って、ブラスト装置１は、投射部２での投射の作業を停止することなく、投射後の研掃材に湿気やごみが付着する前に、回収部３にて研掃材の回収作業を行うことができる。以上より、研掃材の使用量を低減すると共に、作業効率を向上できる。 The blasting device 1 includes a projection section 2 for projecting the abrasive and a collection section 3 for collecting the projected abrasive. As described above, the blasting device 1 is provided with the recovery unit 3, and the blasting device 1 recovers the abrasive once projected onto the object in the recovery unit 3, so that it can be reused without being discarded. can. The recovery unit 3 can recover the abrasive while the projection unit 2 is projecting the abrasive. Therefore, the blasting apparatus 1 does not stop the blasting operation in the blasting unit 2, and collects the abrasive in the recovery unit 3 before moisture and dust adhere to the abrasive after blasting. be able to. As described above, it is possible to reduce the usage amount of the abrasive and improve the working efficiency.
　なお、従来のブラスト装置は、貯蔵部６を介して噴射装置１１から研掃材を投射する作業と、バキュームクリーナで研掃材をコレクトタンクに回収してフレコンバッグに入れて廃棄する作業と、フレコンバッグの研掃材をクレーンで貯蔵部６に入れる作業とが、互いに独立した作業として行われる。このように、各作業が独立して行われるため、作業効率が低い。これに対し、本実施形態に係るブラスト装置１は、投射、回収、貯蔵、及び補給が一組の装置でユニット化された状態で構成される。従って、ブラスト装置１は、投射、回収、貯蔵、補給というサイクルを止めることなく、研掃材のリサイクルを可能とし、工数削減、及び経費圧縮を実現可能である。また、作業者の作業は船舶１００の内部で完結するため、天気に影響されることなく、全天候型で作業を行うことができる。例えば、従来のブラスト装置の研掃材の使用予実が２．８２倍であるのに対し、本実施形態に係るブラスト装置１を用いることで１以下にすることができる。また、研掃材の補給時間が従来のブラスト装置では２０時間であったものを、本実施形態に係るブラスト装置１を用いることで、５時間以下にすることができる。 In addition, the conventional blasting apparatus includes a work of projecting the abrasive from the injection device 11 through the storage unit 6, a work of collecting the abrasive in a collection tank with a vacuum cleaner, putting it in a flexible container bag and discarding it, The work of putting the abrasive material in the flexible container bag into the storage unit 6 with a crane is performed as work independent of each other. Since each work is performed independently in this way, work efficiency is low. On the other hand, the blasting apparatus 1 according to this embodiment is configured in a state in which the projection, recovery, storage, and replenishment operations are unitized as a set of devices. Therefore, the blasting apparatus 1 can recycle the abrasive without stopping the cycle of blasting, recovering, storing, and replenishing, and can reduce man-hours and costs. In addition, since the worker's work is completed inside the vessel 100, the work can be performed in all weather conditions without being affected by the weather. For example, while the actual use of the abrasive material of the conventional blasting apparatus is 2.82 times, the use of the blasting apparatus 1 according to the present embodiment can reduce it to 1 or less. Further, the replenishment time of the abrasive cleaning material, which was 20 hours in the conventional blasting apparatus, can be reduced to 5 hours or less by using the blasting apparatus 1 according to the present embodiment.
　回収部３は、投射部２で投射対象に当たって落下した研掃材を回収してよい。これにより、回収部３は、投射部２が研掃材の投射を行っている一方で、投射対象の下方に貯まった状態の研掃材を回収できる。 The recovery unit 3 may recover the abrasive that has fallen by hitting the projection target with the projection unit 2 . As a result, while the projection unit 2 is projecting the abrasive, the recovery unit 3 can recover the abrasive accumulated below the projection target.
　回収部３で回収した研掃材を投射部２にて再利用してよい。これにより、研掃材の使用量を低減できる。 The abrasive material recovered by the recovery unit 3 may be reused by the projection unit 2. As a result, the amount of abrasive used can be reduced.
　投射部２と回収部３は、一つのカーゴタンク内で投射及び回収を行ってよい。例えば、投射部２及び回収部３を複数のカーゴタンクに設ける場合（例えば、投射部２をあるカーゴタンクに設け、回収部３を別のカーゴタンクに設ける場合）、それぞれのカーゴタンクの容量が異なると、回収する研掃材の量と投射する研掃材の量がばらばらになり、回収して投射する研掃材が足りなくなる可能性がある。これに対し、投射部２と回収部３が、一つのカーゴタンク内で投射及び回収を行う場合、回収して投射する研掃材が足りなくなることを抑制できる。 The projection unit 2 and recovery unit 3 may perform projection and recovery within one cargo tank. For example, when the projection unit 2 and the recovery unit 3 are provided in a plurality of cargo tanks (for example, when the projection unit 2 is provided in one cargo tank and the recovery unit 3 is provided in another cargo tank), the capacity of each cargo tank is If they are different, the amount of abrasive to be collected and the amount of abrasive to be projected will be different, and there is a possibility that the amount of abrasive to be collected and projected will be insufficient. On the other hand, when the projection part 2 and the collection part 3 perform projection and collection in one cargo tank, it is possible to prevent the shortage of the abrasive material to be collected and projected.
　回収部３は、粉塵及び研掃材を回収するモードと、粉塵のみを回収するモードと、を有してよい。この場合、回収部３は状況に応じてモードの切替を行うことができる。 The collecting unit 3 may have a mode for collecting dust and abrasives and a mode for collecting only dust. In this case, the recovery unit 3 can switch modes depending on the situation.
　回収部３は、回収ラインＬ１０を介して、研掃材を吸引する吸引部４と接続され、回収ラインＬ１０の中途位置には、研掃材を貯めておく貯蔵部６が設けられ、吸引部４で吸引された研掃材のうち、貯蔵部６内に落下して堆積するものが、投射部２にて再投射される研掃材として貯蔵されてよい。回収ラインＬ１０は、吸引部４で発生した吸引力を回収部３に伝達すると共に、回収部３で回収した研掃材を貯蔵部へ移送するための移送路として機能することができる。 The recovery section 3 is connected to a suction section 4 for sucking the abrasive through a recovery line L10. Of the abrasives sucked in 4 , those that fall and accumulate in the storage section 6 may be stored as abrasives to be re-projected by the projection section 2 . The collection line L10 transmits the suction force generated by the suction section 4 to the collection section 3, and can function as a transfer path for transferring the abrasive material collected by the collection section 3 to the storage section.
　回収部３で回収された粉塵は、吸引部４によって貯蔵部６に吸引され、当該貯蔵部６内から更に吸引部４へ吸引されてよい。この場合、貯蔵部６において、研掃材と粉塵を分離することができる。 The dust collected by the collection unit 3 may be sucked into the storage unit 6 by the suction unit 4 and further sucked into the suction unit 4 from inside the storage unit 6 . In this case, the abrasive and dust can be separated in the storage section 6 .
　ブラスト装置１は、投射部２で投射する研掃材の不足分を補給する補給部７を更に備えてよい。この場合、研掃材が不足した場合に、補給部７が研掃材を補給することができる。 The blasting device 1 may further include a replenishment section 7 for replenishing the shortage of the abrasive material projected by the projection section 2 . In this case, when the abrasive is insufficient, the supply unit 7 can supply the abrasive.
　上述のブラスト装置１は、船舶１００に設けられてよい。この場合、ブラスト装置１は、船舶１００内の構造物に対して研掃材を投射することができる。 The blasting device 1 described above may be provided on the ship 100 . In this case, the blasting device 1 can project the abrasive against the structure inside the ship 100 .
　本実施形態に係る船舶１００は、上述のブラスト装置１を有する。 The ship 100 according to this embodiment has the blasting device 1 described above.
　本実施形態に係る船舶１００は、上述のブラスト装置１と同趣旨の作用・効果を得ることができる。 The ship 100 according to this embodiment can obtain the same functions and effects as the blast device 1 described above.
　本発明は、上述の実施形態に限定されるものではない。 The present invention is not limited to the above-described embodiments.
　例えば、上述の実施形態では、船舶にブラスト装置が設けられているが、一般の工場や橋梁などの現地工事現場のブラスト装置に適用されてもよい。 For example, in the above-described embodiment, the ship is provided with a blasting device, but it may be applied to a blasting device in a general factory or on-site construction site such as a bridge.
　また、上述の各構成要素の配置は一例であり、本発明の趣旨を逸脱しない限り、適宜変更可能である。 Also, the arrangement of each component described above is an example, and can be changed as appropriate without departing from the scope of the present invention.
