Description

【０００１】
【発明の属する技術分野】
この発明は、壁面、又は建屋内等に設置される遠心噴霧装置付き換気扇、送風扇等の農畜産用扇（農事用扇、畜産用扇）に関する。
【０００２】
【従来の技術】
従来、この種の遠心噴霧装置付き換気扇、送風扇等の農畜産用扇としては、例えば、図１４に示した空間における専有面積が大きいドラム形の円筒本体（ケーシング）（ａ）内に設けたファン（ｂ）と、このファンを駆動するモータ（ｃ）、及びこのファンで回転するガード付きの遠心回転体（ｄ）（回転板）と、この回転板に液体を供給又は回収する供給管（ｅ）、回収管（ｆ）と、この供給管、回収管が接続されるタンク（図示せず）とを設けた構造がある。この遠心回転体をモータで回転し、この遠心回転体にタンク内の水を供給し、この遠心回転体の高速回転を利用して、この水を霧化（細霧化）し、この細霧粒子を、遠心回転体の高速回転を介して霧状として拡散する構成である。この拡散噴霧を介してハウス、鶏舎、豚舎等の冷却と、消毒、又は葉面の清浄化等を目的とする。そして、この種の遠心噴霧装置付き換気扇、送風扇等の農畜産用扇は、地上設置方式と、ハウス空間設置方式とによる使用方式がある。そして、結果的には、円筒本体内に設けたファンと霧化装置とを利用して、冷却（冷房）、消毒等を図ることを目的とする。
【０００３】
しかし、この構造では、ケーシングの内面側を流れる風の流速（ｇ）が速い。この速い流速により、ケーシングの内面に付着、又は浮遊する大粒な流体が飛散する。この大粒の流体の飛散は、作物の濡れ、濡れに起因する病気の発生等の弊害が発生すること、霧化に長い気化時間を要することと、このように時間を要することはエネルギーロスであること、又は遠くに飛ばすのに要するエネルギーが増えることでエネルギーロスが発生すること、等の課題が考えられる。尚、図中で示した▲１▼は測定面を示す。また数字は、風の風速を示す。そして、（ｇ−１）は遠心噴霧装置に衝突する風速を示す。
【０００４】
またこれに類する文献として、特公表０９８／０５４３２号の散霧装置および散霧方法がある（文献とする）。その内容は、散霧装置を構成する送風ファンの回転駆動軸に取付けられた筒体と、この筒体の自由端側に給水管を挿入できるように開口を備えた筒体の周壁には貫通孔を多数開設し、また筒体の周壁の外側に網体を配設し、前記送風ファンによる送風と、筒体の回転を利用して、霧化された粒子（液体粒子）を拡散噴霧する構成であり、例えば、ビニールハウス、温室、畜舎、農作物等に大量の噴霧を行うのに適する散霧装置である。そして、簡易な装置によって大量の細霧を発生させ、広い領域に散布可能とすること、又は冷却（冷房）、消毒等を図ること、等を目的とする。
【０００５】
【発明が解決しようとする課題】
前述の従来技術及び文献は、筒状の枠体に、小型のファンと遠心噴霧装置を設け、この小型のファンの風（送風）と、遠心噴霧装置による噴霧とを利用して、液体の霧化と、この細霧粒子の拡散による冷却及び消毒を図る構成である。しかし、この種の小型ファンと、遠心噴霧装置とによる装置では、次のように問題点が指摘されている。
（イ）広いハウス内においては、効率的な噴霧（霧化）と拡散を図るには、十分でない。また効率的な噴霧と拡散が図れない場合には、多数台（装置）設置する必要があり、不経済である。
（ロ）遠心噴霧装置とファンの組付け構造では、構造面、細霧粒子の発生にも難点がある（粗い粒子「大粒粒子」の発生頻度が大である）。
（ハ）遠心回転体の構造が、単純な一枚構造では、遠心回転体に付着した付着水が飛散し、粗い粒子の拡散による霧化効果の低下、細霧冷房の効率化が図れないこと、又は粗い粒子の滴下による濡れ、薬液障害等の二次的な問題（二次公害）が発生する。
（ニ）換気扇として利用するには、構造的な面での不適合性と、圧損等によるパワー不足が考えられる。
（ホ）ハウス内の塵埃の捕捉を意図した場合には、噴霧能力では、十分な効果は期待できないこと、また目的を達成するには、多数台設置する必要があり、不経済である。
（ヘ）従来の筒状の枠体では、ハウスの壁面に取付けるのに、問題がある。例えば、枠体が突出し、邪魔となること、ハウス内が狭くなること、農業機器の移動に障害となること、埃が溜まること、等が考えられる。
【０００６】
上記に鑑み本発明は、この（イ）〜（ヘ）の問題点を解消することを、包括的な目的とする。以下、その一例を説明する。例えば、図１３に示した如く、枠体は専有面積が少なく、かつ枠体と遠心噴霧装置との間には、大きなスペース（Ｙ）を備えている。従って、風は吸込方向及び枠体外側近傍等より広範囲に導かれ（Ｘ）、かつ遅い流速で送風される（Ｚ）。この遅い流速は、本発明の特徴であって、その効果は、この遅い流速により大粒の流体が飛散することなく、回収部に収容される。また遠心噴霧装置により生成される細かい粒子は、大型のファンの送風力により確実に飛散されること、又は霧化状態の生成に有益である。図中（Ｚ−１）は遠心噴霧装置に衝突する風速を示す。
【０００７】

【００２０】
【発明の実施の形態】
本発明の実施の形態を説明する。
【００２１】
本発明は、方形状のファンケース（チャンネル型材）、鋼線（パイプ）、環状枠等の空間仕切面積を少なくした枠体であり、壁面に設置しても、当該壁面の内外に突出しないので、例えば、前述の（ヘ）の問題点の解消となる。またハウス内における面積の有効活用ができる。
【００２２】
この設置した、本装置のモータを駆動して農畜産用扇の大型のファン（プロペラファン）を回転する。この回転と同時に、他のモータを駆動して遠心回転体を回転する。この農畜産用扇の略全面開放された吸込側より吸込まれた風は、当該農畜産用扇のファンの回転により略全面開放（前面開放）された送風側に至り、この前面開放よりハウス内（農事用の建屋、家畜用の建屋を含む）に拡散送風される。従って、この送風側領域にセットされた遠心噴霧装置に確実に送風される。また遠心噴霧装置では、タンク内のポンプを介して当該タンク内の液体（水、薬液等）を、遠心回転体の略筒部に供給する（滴下する）。この液体は、この略筒部で最初に拡散された後、当該遠心回転体の内壁面に至る。この遠心回転体の高速回転を介して細霧状態で噴霧されて、当該遠心回転体の周辺の隙間から吐出されると、瞬時に農畜産用扇の拡散送風に導かれて素早く拡散される。この略筒部への液体の供給は、この液体の落下防止と、液体の遠心回転体へのスムーズな誘導を図り、二次公害と、確実かつスムーズな霧化、又は霧化の効率化、低コスト化等を意図する。
【００２３】
この際、遠心回転体は、例えば、対峙関係の二枚の回転板で構成されていることから、タンクの液体は、この各回転板の内面をなめるようにして移動し、大粒状化を回避して、薄膜状態から細霧状態となって遠心力の作用により飛散される（移動する）。これにより、周辺の噴霧隙間から霧化されて吐出される（図１１、図１２中に矢印▲２▼で示す）。この霧化された粒子は、遅い流速（Ｚ）により噴霧部に導かれた後、エリミネータの働きで小粒子が（小微粒子のみが）素早く拡散される（図１１、図１２中に矢印▲２▼’で示す）。従って、従来の弊害の一つである、ファンを囲繞する円筒本体による細霧の飛散阻止及び／又は粗大化した粒子の飛散防止等をなくすことができる。
【００２４】
前記略全ての細霧が、拡散送風に導かれる。しかし、その一部は、周辺隙間より滴下し、回収部に至る。この回収部内に滴下した（図１１、図１２中に矢印▲３▼で示す）大粒状化した流体は、回収管を介してタンクに導かれる。即ち、循環使用し、経費の削減と、二次公害の解消等を図る。
【００２５】
尚、この例では、換気扇、送風扇等の農畜産用扇と、遠心噴霧装置とは、個別に構成されており、この個別の遠心噴霧装置を、農畜産用扇に枠組み構成される。即ち、農畜産用扇の送風側を略前面開放し、この前面開放した送風領域に前記遠心噴霧装置をセットする。この例では、農畜産用扇と遠心噴霧装置との間に空気帯域を形成し、ファンより送風される風を、空気帯域を介してガードに緩やかに衝止することで、騒音の発生を減少し、またこの遠心回転体に対する衝撃緩和を図る。
【００２６】
【実施例】
以下、本発明の一実施例を説明する。

【００２８】
図において、１は壁面、又は建屋内等に設置される農畜産用扇で、この農畜産用扇１は、空間における専有面積を小さくしたファンケース、鋼線、環状枠等でなる枠体２と、この枠体２に設けた第１支持具３と、この第１支持具３に設けたモータ４と、このモータ４の出力軸４００に設けたファン５と、前記ファン５を囲繞するベルマウス６とで構成される。そして、この農畜産用扇１の送風側は、前面開放Ａとなっていることが特徴である。この枠体２に付設した第１支持具３に、モータ４を設ける一例を説明する。図１、図２の例（ベルト駆動ファン）では、モータ４を枠体２の隅部に設け、このモータ４の出力軸４００に設けたプーリ４０１の回転をベルト４０２でプーリ４０３に伝達し、このプーリ４０３の回転を回転軸４０４に伝達する。この回転軸４０４にファン５を固止する。他の図３〜図１０の例（直結駆動ファン）では、モータ４の出力軸４００にファン５を設ける。
【００２９】
図中３００は第１支持具３の支持部、４０５はモータ４の支持部である。
【００３０】
図において、１０は遠心噴霧装置で、この遠心噴霧装置１０は、枠体２に設けた第２支持具１１と、この第２支持具１１（後述するガード又は固定板）に設けたモータ１２と、このモータ１２の出力軸１２００に略筒部１３を設け、この略筒部１３に二枚の回転板１４、１５（遠心回転体）と、この回転板１４、１５間に形成した空間１６（大小の例を示した）と、また当該回転板１４、１５の周縁部（周辺）に形成したスリット式（形態）の噴霧部１７と、前記枠体２（第２支持具１１）に必要により設けた曲面状のガード１８と、供給管１９及び回収部２０００並びに回収管２０とで構成されている。尚、ガード１８は、略皿状の形態に限定されず、パイプ、板、ネット等の支持体も可能である。このカード１８の形態は、使用分野、ハウス等の建屋の広さ等により変更、又は選択される。そして、このガード１８の省略、偏平化、又は小寸法化等を図ることで、当該遠心噴霧装置１０の小型化と、農畜産用扇１と遠心噴霧装置１０との間に、空気帯域Ｂを大きく形成できること、又は軽量化、低コスト化、経費の削減化等が図れる。そして、前記農畜産用扇１のモータ４と、この遠心噴霧装置１０のモータ１２とを一基で併用する構造も可能である。この例では、併用したモータの軸（図示せず）と農畜産用扇１及び回転板１４、１５の軸間に、減速機、継手等の部材を設けることが望ましい（図示せず）。例えば、ファン５と回転板１４、１５との回転差の調整、又は軸間の位置修正等を意図する。
【００３１】
図中２１はモータ１２に付設した固定板２２の先端に設けたエリミネータで、このエリミネータ２１は、図１１に示した大小の回転板１４、１５の構造に、霧化を促進するために設け、また粗い粒子の発生回避と、この粗い粒子の滴下による濡れ、薬液障害等の二次的な問題発生回避にある。また図１２に示す同寸（同じ寸法及び／又は対峙形態）の回転板１４、１５では、ガード１８は設けないが、必要により採用する。この例では、ガード１８を設けないので、装置の簡略化、軽量化、組立ての容易化、又は低コストでの提供等の利点がある。
【００３２】
尚、前記回転板１４、１５には、凹凸形状を設けて、液体の細霧に役立つ面積拡大を意図する。尚、凹凸形状は、この例に限定されず、渦巻き形状、放物線形状等も可能である。そして、この同寸の回転板１４、１５では、根元（略筒部１３に設けた箇所）が広く、噴霧部１７（噴霧隙間）に向って、順次絞り込みをかけ、しかも略相対形状とした構成である。またその周縁部を、スリット式の噴霧部１７にし、このスリット式の噴霧部１７にエリミネータ２１を装置したことで、小微粒子の拡散を促進できること、又は粗い粒子の滴下による濡れ、薬液障害等の二次的な問題発生回避ができること等の特徴がある。尚、小寸法の回転板１５は、モータ１２の出力軸１２００への液体の流れを防止し、また細霧の促進化、粗い粒子滴下、二次的な問題発生回避等を図る。
【００３３】
図において、３０はタンクで、このタンク３０には供給管１９と、回収管２０とが接続されており、タンク３０に配したポンプ３１は前記供給管１９に接続されている。尚、図示しないが、例えば、タンク３０は別置き方式、水道直結方式等も採用できる。即ち、タンク３０の形態は、使用するエリア、目的等に対応して適宜選択する。
【００３４】
尚、前記農畜産用扇１と遠心噴霧装置１０との間に形成した空気帯域Ｂは、農畜産用扇１からの送風に対する遠心噴霧装置１０の緩衝用、またこの送風のスムーズな流れと、細霧粒子の拡散確保及び／又は粗い粒子の発生回避等を意図する。
【００３５】
本発明は、枠体２を利用して壁面、又は建屋内等に設置される構造であり、壁面設置は、外気供給に際して、直接的な冷房又は塵埃の捕捉等が図れる。また建屋隅の薬液（溶液、消毒液等の液体）、水等の液体散布も可能である。また建屋内設置は、室内空気（広範囲）の冷房又は消毒の効率化、塵埃の捕捉等が図れる。また建屋内の薬液、水等の液体散布も可能である。当然、壁面、又は建屋内等の併設もできる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an agricultural / livestock fan (agricultural fan, livestock fan) such as a ventilation fan with a centrifugal spray device, a blower fan, and the like, which is installed on a wall surface, a building, or the like.
[0002]
[Prior art]
Conventionally, as this kind of agriculture and livestock fans such as a ventilation fan with a centrifugal spray device and a blower fan, for example, provided in a drum-shaped cylindrical main body (casing) (a) having a large occupation area in the space shown in FIG. A fan (b), a motor (c) for driving the fan, a centrifugal rotator (d) (rotating plate) with a guard rotated by the fan, and a supply pipe (supplied or supplied with liquid to the rotating plate) e), a recovery pipe (f), and a tank (not shown) to which the supply pipe and the recovery pipe are connected are provided. The centrifugal rotator is rotated by a motor, water in the tank is supplied to the centrifugal rotator, and the water is atomized (finely atomized) by utilizing the high-speed rotation of the centrifugal rotator. This is a configuration in which particles are dispersed as a mist through high-speed rotation of a centrifugal rotator. Through this diffusion spraying, the purpose is to cool, disinfect, or clean the leaves of houses, poultry houses, pig houses, and the like. Agricultural and livestock fans such as a ventilating fan with a centrifugal spray device and a blower fan of this type are used in a ground installation system or a house space installation system. As a result, the object is to achieve cooling (cooling), disinfection, and the like by using a fan and an atomizing device provided in the cylindrical main body.
[0003]
However, in this structure, the flow velocity (g) of the wind flowing on the inner surface side of the casing is high. Due to the high flow velocity, a large fluid that adheres or floats on the inner surface of the casing is scattered. The scattering of the large-sized fluid may cause adverse effects such as wetting of the crop and the occurrence of diseases caused by the wetting, that the atomization requires a long vaporization time, and that such time is an energy loss. There is a problem that an energy loss occurs due to an increase in energy required to fly a distant object. Incidentally, (1) shown in the figure indicates a measurement surface. The numbers indicate the wind speed of the wind. And (g-1) shows the wind speed colliding with the centrifugal spray device.
[0004]
Further, as a similar document, there is a fogging apparatus and a fogging method disclosed in Japanese Patent Publication No. 098/05432 (hereinafter referred to as a reference). Its contents are a cylinder attached to the rotation drive shaft of the blower fan that constitutes the atomization device, and an opening that allows a water supply pipe to be inserted into the free end of this cylinder. A large number of holes are provided, and a mesh is provided outside the peripheral wall of the cylinder, and the atomized particles (liquid particles) are diffused and sprayed by using the air blown by the blower fan and the rotation of the cylinder. This is a spraying device having a configuration and suitable for spraying a large amount on a greenhouse, a greenhouse, a livestock barn, agricultural products, and the like, for example. Then, a large amount of fine fog is generated by a simple device and can be sprayed over a wide area, or cooling (cooling), disinfection, and the like are intended.
[0005]
[Problems to be solved by the invention]
In the above-mentioned prior art and literature, a small fan and a centrifugal spraying device are provided in a cylindrical frame, and the mist of liquid is sprayed by using the wind (blast) of the small fan and the spraying by the centrifugal spraying device. And cooling and disinfection by diffusion of the fine mist particles. However, the following problems have been pointed out with this type of small fan and centrifugal spray device.
(A) In a large house, it is not enough to achieve efficient spraying and atomization. If efficient spraying and diffusion cannot be achieved, a large number of units (devices) must be installed, which is uneconomical.
(B) In the assembly structure of the centrifugal spray device and the fan, there is also a problem in terms of structure and generation of fine mist particles (coarse particles “large particles” occur frequently).
(C) If the structure of the centrifugal rotator is a simple one-piece structure, the water adhering to the centrifugal rotator is scattered, and the atomization effect is reduced due to the diffusion of coarse particles, and the efficiency of fine mist cooling cannot be improved. Or secondary problems (secondary pollution) such as wetting due to dripping of coarse particles and damage to the chemical solution.
(D) In order to use it as a ventilation fan, it is considered that there is a structural incompatibility and insufficient power due to pressure loss.
(E) If the intention is to capture dust in the house, it is impossible to expect a sufficient effect with the spraying ability, and in order to achieve the purpose, it is necessary to install many units, which is uneconomical.
(F) In the conventional cylindrical frame, there is a problem in mounting it on the wall surface of the house. For example, it is conceivable that the frame protrudes and obstructs, the inside of the house becomes narrow, the movement of agricultural equipment becomes an obstacle, and dust accumulates.
[0006]
In view of the above, it is a general object of the present invention to solve the problems (a) to (f). Hereinafter, an example will be described. For example, as shown in FIG. 13, the frame has a small occupied area and has a large space (Y) between the frame and the centrifugal spray device. Therefore, the wind is guided over a wider range than the suction direction and the vicinity of the outside of the frame (X), and is blown at a slow flow velocity (Z). This slow flow rate is a feature of the present invention, and the effect is that the large flow rate fluid is stored in the collection unit without being scattered by the slow flow rate. Further, fine particles generated by the centrifugal spray device are surely scattered by the blown air of a large fan or are useful for generating an atomized state. In the figure, (Z-1) indicates the wind speed colliding with the centrifugal spray device.

[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described.
[0021]
The present invention is a frame having a reduced space partition area such as a square fan case (channel type material), a steel wire (pipe), an annular frame, and the like, and does not protrude into and out of the wall even when installed on the wall. For example, the above-mentioned problem (f) is solved. In addition, the area in the house can be effectively used.
[0022]
The motor of the installed apparatus is driven to rotate a large fan (propeller fan) of an agricultural and livestock fan. At the same time as this rotation, another motor is driven to rotate the centrifugal rotator. The wind sucked from the suction side of the fan for agriculture and livestock which is almost fully opened reaches the blowing side which is almost completely opened (opened to the front) by the rotation of the fan of the fan for agriculture and livestock. (Including farm buildings and livestock buildings). Therefore, the air is reliably blown to the centrifugal spray device set in the blowing side area. In the centrifugal spray device, a liquid (water, a chemical solution, or the like) in the tank is supplied (dropped) to a substantially cylindrical portion of the centrifugal rotating body via a pump in the tank. The liquid is first diffused in the substantially cylindrical portion, and then reaches the inner wall surface of the centrifugal rotator. When sprayed in a fine mist state through the high-speed rotation of the centrifugal rotator and discharged from a gap around the centrifugal rotator, it is instantly guided by the diffusion blast of the fan for agriculture and livestock, and quickly diffused. The supply of the liquid to the substantially cylindrical portion is intended to prevent the liquid from dropping and to smoothly guide the liquid to the centrifugal rotating body, and to achieve secondary pollution, reliable and smooth atomization, or more efficient atomization, It is intended to reduce costs.
[0023]
At this time, since the centrifugal rotating body is composed of, for example, two rotating plates facing each other, the liquid in the tank moves so as to lick the inner surface of each rotating plate, thereby avoiding the formation of large particles. Then, the state changes from the thin film state to the fine fog state and is scattered (moved) by the action of the centrifugal force. As a result, it is atomized and discharged from the peripheral spray gap (indicated by an arrow (2) in FIGS. 11 and 12). After the atomized particles are guided to the spraying section at a low flow rate (Z), small particles (only small particles) are quickly diffused by the action of the eliminator (arrows 2 in FIGS. 11 and 12). ▼ '). Therefore, it is possible to eliminate one of the conventional adverse effects, such as the prevention of fine mist scattering and / or the prevention of scattered coarse particles by the cylindrical body surrounding the fan.
[0024]
Almost all of the fine fog is guided to the diffused air. However, a part of the liquid drops from the peripheral gap and reaches the collection section. The large-grained fluid (indicated by an arrow {circle around (3)} in FIGS. 11 and 12) dropped into this recovery section is guided to a tank via a recovery pipe. In other words, it is used cyclically to reduce costs and eliminate secondary pollution.
[0025]
Note that, in this example, the agricultural and livestock fans such as the ventilation fan and the blower fan and the centrifugal spray device are separately configured, and the individual centrifugal spray devices are framed as the agricultural and livestock fan. That is, the ventilation side of the fan for agriculture and livestock is opened substantially to the front, and the centrifugal spray device is set in the ventilation area opened to the front. In this example, an air zone is formed between the fan for agriculture and livestock and the centrifugal spray device, and the air blown from the fan is gently stopped against the guard via the air zone to reduce noise generation. In addition, the impact on the centrifugal rotating body is reduced.
