Description

【考案の詳細な説明】 本考案は貯水液の取水装置に関するものである。[Detailed explanation of the idea] The present invention relates to a water intake device for stored water.

燃料燃焼により水を加熱して蒸気を発生させ、この蒸気
熱を各種処理施設、乾燥施設等の作業用に使用し、或は
暖房用に使用するボイラーにいて、常にボイラーに冷水
を供給することは加熱のための燃料消費が大きなものと
なる。Water is heated by fuel combustion to generate steam, and this steam heat is used for various processing facilities, drying facilities, etc., or in a boiler used for heating, constantly supplying cold water to the boiler. The fuel consumption for heating becomes large.

このため温水タンク内に貯水し、この温水をボイラーに
供給して加熱時間の短縮、燃費の低減を図る方法が採用
されているが、タンク内に送り込まれた温水は一般的に
上部液層に比較して底部液層が低温となり、従ってタン
ク下部から取水することは常に低温水をボイラーに供給
する結果となり従前と何ら変わることがない。For this reason, a method has been adopted in which water is stored in a hot water tank and this hot water is supplied to the boiler to shorten heating time and reduce fuel consumption, but generally the hot water sent into the tank flows into the upper liquid layer. In comparison, the bottom liquid layer is at a lower temperature, so taking water from the bottom of the tank always results in supplying low-temperature water to the boiler, which is no different from before.

また、製紙工場において紙製造に使用された大量の水を

取水しなければならない。In addition, in order to circulate and reuse the large amount of water used in paper manufacturing at a paper mill, water containing molten paper sludge is stored in a tank and separated into a sludge layer and a liquid layer. It is necessary to take only the liquid above the sludge layer, but in such a case, only the liquid must be taken without stirring the sludge layer.

第４図に示すように筒体１はタンク１１内に立設固定し
、取水管９はタンク１１外部に設置した適宜吸水装置に
管接続しておく。As shown in FIG. 4, the cylindrical body 1 is erected and fixed inside the tank 11, and the water intake pipe 9 is connected to an appropriate water suction device installed outside the tank 11.

タンク１１内が無水状態の時弁蓋４は、連結杆７と浮動
部材８との重量比により流入口３を開口した状態となる
。When the inside of the tank 11 is in an anhydrous state, the valve cover 4 is in a state in which the inlet port 3 is opened due to the weight ratio of the connecting rod 7 and the floating member 8.

弁蓋４を流入口３方向へ強制的に回動して流入口３を閉
じる。When hot water is supplied into the tank 11, as the water level rises from the bottom, the liquid flows into the cylindrical body 1 from the lowest inlet 3, and as the water level further rises, the floating member 8 floats up and moves the valve lid 4 to the inlet. The inflow port 3 is closed by forcibly rotating in three directions.

同様にして水位の上昇によって各流入口３から筒体１内
に液体が流入するとともに浮動部材８により弁蓋４を閉

みの取水が可能となる。If the upper part of the cylinder 1 is opened, only the upper liquid in the tank 11 can be taken from the upper part of the cylinder 1 with each inlet 3 closed by the valve M4, and the upper part of the cylinder 1 can be closed. If the water level is changed by adjusting the amount of water supplied to the tank 11 and the amount of water taken in so that the liquid flows in from the top inlet 3 in this state, the valve M4 is opened and closed by the vertical movement of the floating member 8, and only the upper liquid flows. water intake becomes possible.

従って、例えばボイラーへの供給のため循環温水をタン
ク内に貯水しても連続的に供給される上部温水のみを取
水でき、下部の冷水を取水することはなくなる。Therefore, for example, even if circulating hot water is stored in a tank for supply to a boiler, only the continuously supplied hot water from the upper part can be taken, and cold water from the lower part cannot be taken.

また、太陽熱を利用して加熱する貯蔵タンク内に本発明
装置を設置すれば、貯水液層の上部高温部の取水が可能
となる。Furthermore, if the device of the present invention is installed in a storage tank that is heated using solar heat, it becomes possible to take in water from the upper high-temperature part of the water storage layer.

The tank 1 is forcibly closed by the floating member 8 and the valve cover 4 is closed.
The water pressure flowing into the valve cover 1 is applied to the receiving plate 12 to maintain the closed state of the valve cover 4.

また、図示しないが弁蓋４を支持する回動軸６をタンク
１１外部において回動操作することにより弁Ｍ４を開閉
動させタンク１１内の任意の液層の取水が可能となる。Further, although not shown, by rotating the rotating shaft 6 that supports the valve cover 4 outside the tank 11, the valve M4 can be opened and closed, thereby making it possible to take water into any liquid layer within the tank 11.
