Description

本考案は微細気泡発生装置に関する。  The present invention relates to a microbubble generator.

現在普及している微細気泡発生装置の主な原理は、コンプレッサー、ベンチュリー管、インペラ、スクリュウ、過流ポンプ等々で加圧し圧送して空気と水の混合した微細気泡Ｂを得ているために、微細気泡Ｂ発生効率が低く運転コストが高いのが現状である。  The main principle of the microbubble generator currently in widespread use is to obtain a microbubble B in which air and water are mixed by pressurizing and pumping with a compressor, a venturi pipe, an impeller, a screw, an overflow pump, etc. At present, the generation efficiency of the fine bubbles B is low and the operation cost is high.

特開２０１１―５３９３号公報が知られている。Japanese Unexamined Patent Publication No. 2011-5393 is known.

［特許文献１］特開２０１１―５３９３号公報の微細気泡発生装置では、軸管２と前記軸管２の先端に取り付けられた胴体３の外周に当該軸管２の回転方向前面、又は径方向先端が円又は球の一部である翼体７を備えたインペラと、前記インペラの所定位置に設けられるとともに、前記胴体３に設けられた空洞と軸管２を介して外気と連通する給気口とを備える微細気泡発生装置であり、この装置の課題は
１−円又は球の一部のインベラを回転させるために、強力な対流を引き起こし、稚魚、幼魚、等を対流に巻き込み損傷などの被害を与える事が問題とされる。
２−給気口に逆止弁が無いために、微細気泡発生装置の運転を停止すれば、給気口より水が軸管２より胴体３内に逆流し、水面位置までに達する不都合がある。
３−汚水の逆流のために軸管２、と胴体３の内面が汚水等でパクテリア等が発生する可能性が高く清掃が必要となる。軸管２、微細気泡発生装置の分解清掃が頻繁に必要となりメンテナンスのための費用が増加する。
４−再起動した時、給気口の口径が小口径なので軸管２と胴体３内の侵入水の排水に長時間を要するので電力経費が増加する。
５−胴体３内にプロワーフィンが無く、インペラの負圧のみで散気するために微細気泡Ｂ量が微少となり微細気泡Ｂ発生効率が低下する。[Patent Document 1] In the microbubble generator disclosed in Japanese Patent Application Laid-Open No. 2011-5393, the axial tube 2 and the outer periphery of the body 3 attached to the tip of the axial tube 2 are rotated in front of the axial tube 2 or in the radial direction.

2- Since there is no check valve at the air supply port, if the operation of the fine bubble generating device is stopped, water flows backward from the air supply port into the body 3 from the shaft tube 2 and reaches the water surface position. .
3- Because of the backflow of sewage, the inner surface of the shaft tube 2 and the body 3 is highly likely to cause pacteria and the like due to sewage, and cleaning is required. The disassembly and cleaning of the shaft tube 2 and the fine bubble generator are frequently required, and the cost for maintenance increases.
4- When restarted, since the diameter of the air supply port is small, it takes a long time to drain the intruding water in the shaft tube 2 and the fuselage 3, so that the power cost increases.
5- There is no pro-fin in the body 3 and the air is diffused only by the negative pressure of the impeller, so the amount of fine bubbles B becomes small and the efficiency of generating fine bubbles B decreases.

FIG. 1 is a schematic plan view of the microbubble generator 1. It is a fine bubble generator 1 composed of a shaft tube 2, a body 3, a ring hinge 4, an air diffusion port 5, a blade plate 6, and a blade body 7.
1- When the shaft tube 2 that ventilates the air is rotated by rotation, the body 3 connected to the lower portion of the shaft tube 2 rotates.
2- When the body 3 rotates, the ring hinge 4 connected to the outer periphery of the body 3 and the wing body 7 loosely penetrated by the ring hinge 4 receive lift and centrifugal force due to underwater movement.
When the 3-axis tube 2 is stationary, the wing body 7 is present in the water, receives water pressure, and is crimped to a plurality of air diffusion ports 5 provided at equal intervals θ from the center of the shaft tube 2. Cover and provide check valve function.
When the 4-axis tube 2 rotates, the wing body 7 receives lift and centrifugal force, and the wing body 7 moves to the outside of the body 3.
5-By moving the wing body 7, the diffuser opening 5 opened in the fuselage 3 is opened, and the diffuser blade 6 provided at the rear in the rotational direction of the fuselage 3 immediately inside the diffuser vent 5 also rotates. Therefore, the air in the shaft tube 2 and the body 3 is communicated, and the vane plate 6 forcibly diffuses the air to the outside of the air diffusion port 5.
6 Forced diffused air becomes bubbles in the water, but the wing body 7 that rotates one after another is cut, divided, and refined, and further, Kalman is formed on both the convex and concave surfaces of the wing body 7. Overflow occurs, and this overflow further refines the bubbles.
The wing body 7 loosely connected to the 7-ring hinge 4 slides. For this reason, the Kalman overflow mass gathering at the rear part of the wing body 7 diffuses widely, and the Kalman overflow mass becomes the surface tension balance of the bubbles. The fine bubbles B are further refined into bubbles.

Fine feelings surround the outside of the ship.

［図７］は気泡発生装置１が水中で回転稼働を停止した状態を示した図である。
回転運動が停止された時には 環ヒンジ４に遊貫されて連結された翼体７は浮力と遠心力を失い さらに停止直前の水の抵抗を受けて散気口５を覆い、散気口を閉塞する、同時に水圧を受けて散気口５周辺に圧着されることにより 微細気泡発生装置１内への水の侵入を防止する状態を示した図である。FIG. 7 is a view showing a state in which the bubble generating device 1 stops rotating in water.
When the rotary motion is stopped, the wing body 7 loosely connected to the ring hinge 4 loses buoyancy and centrifugal force, and further receives the resistance of water immediately before the stop, covers the air diffuser 5 and closes the air diffuser. FIG. 5 is a view showing a state in which water is prevented from entering the fine bubble generating device 1 by being simultaneously compressed by pressure around the air diffusion port 5 by receiving water pressure.

［図８］は微細気泡発生装置が水中で稼働している状態を示した図である。
微細気泡発生装置１が稼働して高速回転する時、環ヒンジ４に遊貫され連結された翼体７に大きな揚力と翼体７の質量に応じた遠心力により散気口５を開口する。この時微細気泡発生装置１内に設けられた羽根板６も同時に回転することにより胴体３近辺の空気を羽根板６が圧縮し散気口５から水中へ強制的に散気し、大量の気泡を発生させることを示した図である。FIG. 8 is a view showing a state where the fine bubble generating device is operating in water.
When the microbubble generator 1 operates and rotates at a high speed, the air diffuser 5 is opened by a large lift and a centrifugal force corresponding to the mass of the wing body 7 in the wing body 7 loosely connected to the ring hinge 4 and connected thereto. At this time, the blade 6 provided in the fine bubble generator 1 also rotates at the same time, so that the blade 6 compresses the air in the vicinity of the fuselage 3 and forcibly diffuses it into the water from the air diffuser port 5. It is the figure which showed generating.

［図９］は微細気泡発生装置１が稼働して居る時、環ヒンジ４と翼体７との関係をより詳細に説明した概略図である。
微細気泡発生装置１が回転運動をする時 環ヒンジ４に連結された翼体７は翼体孔７ａに遊貫されているために激しく揺動する。翼体７前方に浮遊する気泡が揺動する翼体７に衝突して浮遊気泡を更に微細気泡化する、
さらに翼体７の凸部７ｂはカルマン過流を生じるが翼体孔７ａで生じた揺動を受けて激しく振動する。それによりカルマン過流も振動して複数のカルマン過流を生じる。
さらに翼体７の後部７後方には翼体７の７ｂ凸部と７ｃ凹部には相反するカルマン過流を生じる。この相反するカルマン過流が翼体７の後部７ｄ後方で合流するため翼体７の後部７ｄの後方ではカルマン過流が複雑な水圧変動を起す。
それにより微細気泡内のバランスが崩れて更なる微細気泡化を生じることを示した図である。FIG. 9 is a schematic diagram illustrating the relationship between the ring hinge 4 and the wing body 7 in more detail when the microbubble generator 1 is operating.
When the microbubble generator 1 rotates, the wing body 7 connected to the ring hinge 4 swings violently because it is loosely penetrated into the wing body hole 7a. The air bubbles floating in front of the wing body 7 collide with the oscillating wing body 7 to further refine the air bubbles.
Further, the convex portion 7b of the wing body 7 causes Kalman overflow, but vibrates violently in response to the oscillation generated in the wing body hole 7a. As a result, the Kalman overflow also vibrates to generate a plurality of Kalman overflows.
Further, the Kalman overflow is generated behind the rear portion 7 of the wing body 7 in the 7b convex portion and the 7c concave portion of the wing body 7. Since the opposite Kalman overflow merges behind the rear portion 7d of the wing body 7, the Kalman overflow causes complicated water pressure fluctuations behind the rear portion 7d of the wing body 7.
It is the figure which showed that the balance in a fine bubble collapse | crumbles and thereby produces further fine bubble formation.

［図１０］は環ヒンジと翼体の立体概略図である。
翼体７は環ヒンジ４の一端に回動自在に遊勘されている。
更に翼体７は散気口５を開閉するように他端を胴体３に溶着してある環ヒンジ４の支持プレート４ａで回動自在に保持されている。FIG. 10 is a three-dimensional schematic diagram of the ring hinge and the wing body.
The wing body 7 is freely swung around one end of the ring hinge 4.
Further, the wing body 7 is rotatably held by a support plate 4a of a ring hinge 4 whose other end is welded to the body 3 so as to open and close the air diffusion port 5.

水産養殖場の曝気装置としては水産養殖事業の今後の成長は大いに期待されるが、同時に大きな危険が潜んでいる。其れは池、沼、等の開鎖水域での養殖で問題が起こり易い。
閉鎖水域での水産養殖の特徴は、池水が流動しないために比重の重い配合飼料の残飼料、養殖物の生理***物が、池水の底に滞留し、その有機質が酸化、還元する際に大量の水中酸素を消化するために、酸紫が不足するために嫌気性バクテリアが繁殖し、この嫌気性バクテリアが養殖物を被病させ、成長力を下げる。
そこで本徴細気泡発生装置を養殖池の底に設置し稼働させれば、激しい対流も無く大量に微細気泡Ｂを発生し、その微細気泡Ｂが緩やかに水中を上昇して行く過程で、池水への酸素交換が進行して、養殖水の溶存酸素加給効果が高まり稚魚、稚貝の被害も無く好気性バクテリアを大量に増殖し、それを動、植物プランクトンが食餌して増殖し、其れが養殖物の稚魚、稚貝、稚エビ、等の天然飼料として食餌し、健康的で元気で速やかに成長する。
また、観賞魚水槽の水質管理用としては、水槽の水質は観賞魚の健康に大きく関係致します、頻繁な用水交換が求められますが本考案の微細気泡Ｂを発生させて溶存酸素量を高める事で用水の交換回数も減るので管理が安易となり更に観賞魚もより健康に成る。As aeration equipment for aquaculture farms, the future growth of the aquaculture business is highly expected, but at the same time there is a great danger. It is prone to problems in aquaculture in open-chain waters such as ponds and swamps.
The characteristics of aquaculture in a closed water area are that, because pond water does not flow, residual feed of heavy mixed feed and physiological excrement of the cultured product stay at the bottom of the pond water, and a large amount of organic matter is oxidized and reduced. In order to digest oxygen in the water, anaerobic bacteria are propagated due to the lack of acid purple, and this anaerobic bacteria causes the cultured product to become ill and reduce its growth potential.
Therefore, if this fine bubble generating device is installed and operated at the bottom of the culture pond, a large amount of fine bubbles B are generated without intense convection, and the pond water As the oxygen exchange proceeds to the water, the effect of supplementing dissolved water on the aquaculture water is increased, and a large amount of aerobic bacteria are grown without damage to the fry and larvae. However, it is eaten as a natural feed for cultured fish, larvae, shrimp, etc., and grows healthy, healthy and quickly.
In addition, for the quality control of the aquarium fish tank, the water quality of the aquarium is greatly related to the health of the aquarium fish. Frequent water exchange is required, but the fine bubbles B of the present invention are generated to increase the amount of dissolved oxygen. Since the number of water exchanges is reduced, the management becomes easier and the ornamental fish become healthier.
