この発明は、多種類の化学物質を荷役効率良く運搬でき
るケミカルタンカーに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chemical tanker that can efficiently transport a wide variety of chemical substances.
従来、化学工業に釦いて生産されるリン、四エチル鉛、
酸化プロピレン等の一次または二次製品を目的地まで輸
送するためのケミカルタンカーがあるが、このケミカル
タンカーのタンク構造は、パーセル方式と云われる上甲
板下に設けられた複数の升目状タンクで構成されていて
、前記複数の升目状タンク内に多種類の化学物質を積込
んで輸送することになっている。Traditionally, phosphorus, tetraethyl lead, and
There are chemical tankers that transport primary or secondary products such as propylene oxide to their destinations, but the tank structure of these chemical tankers is called the parcel system, which consists of multiple square-shaped tanks installed under the upper deck. A variety of chemical substances are loaded into the plurality of square-shaped tanks and transported.
このため前記各タンクには、各々独立した没水型のポン
プが設置されているが前記没水型のポンプは非常に高価
格であるので費用がカ・かる。For this reason, each of the tanks is equipped with an independent submersible pump, but the submersible pump is very expensive and therefore expensive.
また、前記各タンクは甲板下に設置されているので、荷
役用配管も甲板上に立上る構造となる。Furthermore, since each of the tanks is installed below the deck, the cargo handling piping also rises above the deck.
このため配管及びタンク内にどうしても吸上げきれない
残貨が発生し、貨物が高価なものである場合には多大の
損失となる。As a result, residual cargo that cannot be sucked up is generated in the piping and tanks, resulting in a large loss if the cargo is expensive.
また、危険な多量の残貨はタンククリーニングに支障を
来たし、廃液処理に困難を伴なう。In addition, a dangerously large amount of residual material interferes with tank cleaning and makes waste liquid treatment difficult.
更に、升目構造の複数のタンクが直接船体強度と関連す
るため建造コストが高くつく管種々の問題がある。Furthermore, since the plurality of tanks having a square structure are directly related to the strength of the hull, there are various problems that increase the construction cost.
この発明は、上述のような観点力）ら多種類の化学物質

た開口に接続してなることに特徴を有する。This invention provides an economical chemical tanker that can load and unload many kinds of chemicals without leaving any residue and by using inexpensive pumps. A part of the tank is fixed via a transformer material and a longitudinal part, and the other part of the tank on the deck is fixed to a plurality of supporting members that are continuously fixed to the bottom of the tank in the width direction of the hull. In order to reinforce the upper deck, it is supported on the upper deck by being placed on supporting materials fixed continuously in the width direction of the hull, so that deformation in the longitudinal direction of the hull is not transmitted to the tank above the deck. The deck tanks are arranged at multiple intervals in the longitudinal direction of the hull, and a cargo handling pump is provided on the upper deck between the deck tanks, and the cargo handling piping from the cargo pump is connected to the deck tank. It is characterized by being connected to an opening formed at the bottom of the tank.

タンク９ａ 。A plurality of compartment tanks 9a by 9b', 9c'-9f'.
９ｂ、９ｃ・・・９ｆに区画されている。It is divided into 9b, 9c...9f.
前記デツキ上タンク９は後述する支持部材１９により上
甲板２上に適当な空間１２をあけて固定支持されている
。The deck tank 9 is fixedly supported on the upper deck 2 with an appropriate space 12 by a support member 19, which will be described later.
尚、１３はデツキ上タンク９の周囲に配置されたデツキ
上タンク９の補強材であり、１４．１５はバラストタン

状態で固定支持されている。That is, as shown in FIGS. 5 to 7, the upper deck 2
A part of the deck upper tank 9 is fixed on top by a transformer material 16 arranged in the width direction of the hull and a partial longitudinal material 17 arranged in the longitudinal direction of the hull 1, and the other part is fixed only in the width direction of the hull. A bottom support member 18 that also serves as a reinforcement for the upper deck tank 9 is placed and fixedly supported on a support member 19 that also serves as a reinforcement for the upper deck 2.
従って、船体１にその長手方向の変位、すなわちホギン

置当接状態で上甲板２上に支持されているので、前記変
形応力はデツキ上タンク９には伝わらない。Therefore, even if the hull 1 undergoes longitudinal displacement, ie, deformation such as hogging or sagging, the upper deck 2 and the upper deck tank 9 will be affected by the transformer material 16 and the partial longitudinal material 1.
7 is partially fixed, and the other parts are supported on the upper deck 2 in a state of mounting and contact, so that the deformation stress is not transmitted to the upper deck tank 9.
このため、デツキ上タンク９の構造を軽量構造にするこ
とができる。Therefore, the structure of the upper deck tank 9 can be made lightweight.
第５図に示される実施例は、デツキ上タンク９の後方に

上タンク９への影響は少なく、船体１長手方向にわたる
一体型のタンクより軽量構造にできることは明白である
。Incidentally, since the above-mentioned deck tanks 9 are arranged at intervals of 10, from this point of view as well, the influence of the above-mentioned hull deformation on the deck tanks 9 is small, and compared to an integrated tank extending in the longitudinal direction of the hull 1. The potential for lightweight construction is obvious.
前記間隔１０にはデツキ上タンク９の貨物用荷役ポンプ
が設置される。A cargo handling pump for the upper deck tank 9 is installed in the interval 10.
この荷役配管について、第８図及び第９図を参照しなが

and the upper deck 2 (see Figure 4).
The transformer material 16 shown in FIGS. 5 and 6 provided in the width direction
, are piped through the supports 18,19.
すなわち、前記空間１２が前記配管の有効スペースとし

前記荷役配管は以上の如く配設されているので、デツキ
上タンク９内の貨物は、底板９”の開口２３より荷役ポ
ンプ２０により吸出される。Since the cargo handling piping is arranged as described above, the cargo in the upper deck tank 9 is sucked out by the cargo handling pump 20 through the opening 23 in the bottom plate 9''.
この結果、前記荷役ポンプ２０には重力ヘッドが作用す

内には銭貨が発生しないので、高価な貨物に対しては極
めて有効である。As a result, since the gravity head acts on the cargo handling pump 20, the suction power can be reduced, and the tank on the deck can be reduced in size.
Since no coins are generated inside the system, it is extremely effective for high-value cargo.
尚、貨物タンク５内の荷役配管は従来と同様であるので
説明は省略する。Note that the cargo handling piping inside the cargo tank 5 is the same as the conventional one, so a description thereof will be omitted.

る。As explained above, according to the present invention, (1) In order to load various types of cargo on the upper deck of a deck provided on the upper deck, the upper deck tank is divided into a plurality of tanks, and the tanks are spaced apart in the longitudinal direction of the hull. In addition, the structure is such that only a portion of each deck upper tank is fixed to the hull, and the other portions are placed on and in contact with the upper deck, so that deformation in the longitudinal direction of the hull does not affect the deck upper tanks. There is no risk of the transmission being transmitted as is, and as a result, the deck tank can be made lightweight, which is very advantageous in terms of cost.Also, since the deck tank can be mounted as one tower, the hull construction cost can be greatly reduced. savings can be achieved.
■ 各デツキ上タンクの底部に荷役配管を接続しデツキ
上タンクの底部から荷役するようにしたので、デツキ上
タンク内及び荷役配管内に銭貨が生じることはなく無り
、貨物を吸出する際の動の節減にもなる。■ Cargo handling piping is connected to the bottom of each deck upper tank and cargo is handled from the bottom of the deck upper tank, so there is no coins in the deck upper tanks or cargo handling piping, and when the cargo is sucked out. It also saves on movement.
■ 荷役ポンプは上甲板上に設置されるものであるから
、従来のように没水型の高価なポンプを必要とせず、通
常の安価な非没水型のポンプを使用できるので設備費が
大巾に低減できる。■ Since the cargo handling pump is installed on the upper deck, there is no need for an expensive submersible pump as in the past, and instead a regular inexpensive non-submersible pump can be used, reducing equipment costs. It can be reduced to width.
管種々の有用な効果がもたらされる。The tube provides a variety of useful effects.
