Description
本発明は、ダイアフラム式のブロワー装置に関するものである。
The present invention relates to a diaphragm type blower device.
圧縮空気を送り出すブロワー装置は、液体中に空気を吹き込むため（曝気或いはエアレーション）などに用いられている。ブロワー装置の構造は、容積形とターボ形に分けられるが、容積形のブロワー装置は、ルーツを回転させて作動空間の体積変化を起こさせる回転式と、ダイヤフラムなどを往復動させて作動空間の体積変化を起こさせる往復式が知られている。
A blower device that sends out compressed air is used to blow air into liquid (aeration or aeration). The structure of a blower device is divided into a positive displacement type and a turbo type.The positive displacement type blower device is a rotary type that rotates the roots to cause a change in the volume of the working space, and a reciprocating diaphragm to move the working space. A reciprocating system that causes a volume change is known.
ダイヤフラムを用いた往復式のブロワー装置は、電磁振動式のものが多く、駆動軸の左右両端にダイヤフラムを対向して接続し、駆動軸を軸方向に往復振動させることで、左右のダイヤフラムを振動させて、各ダイヤフラムの外側にそれぞれ形成されている左右の作動空間の体積を交互に収縮・拡大させている。このようなブロワー装置は、左右の作動空間の一方が収縮しているときには、その一方の作動空間に設けた吸気弁が閉じて吐出弁が開くことで空気の吐出が行われ、その間、他方の作動空間は拡大して、その他方の作動空間に設けた吸気弁が開いて吐出弁が閉じることで空気の吸入が行われる（下記特許文献１参照）。
Many reciprocating blower devices that use a diaphragm vibrate electromagnetically, and the diaphragms on both sides are vibrated by connecting the diaphragms to the left and right ends of the drive shaft so that they face each other and reciprocally vibrating the drive shaft in the axial direction. By doing so, the volumes of the left and right working spaces formed outside the respective diaphragms are alternately contracted and expanded. In such a blower device, when one of the left and right working spaces is contracted, air is discharged by closing the intake valve provided in the one working space and opening the discharge valve, while the other of the working spaces is closed. Air is sucked by expanding the operating space and opening the intake valve and closing the discharge valve provided in the other operating space (see Patent Document 1 below).
また、ダイヤフラム式のブロワー装置としては、同軸に配置した二つの駆動軸を互いに逆向きに同期して電磁振動させ、各々の駆動軸の外側に対向して接続したダイヤフラムを近接・離間させることで、各ダイヤフラムの外側にそれぞれ形成されている左右の作動空間の体積を同時に収縮・拡大するものも提案されている（下記特許文献２参照）。
Further, as a diaphragm type blower device, two drive shafts arranged coaxially are electromagnetically oscillated in a mutually opposite direction in synchronization with each other, and diaphragms connected so as to face the outside of each drive shaft are brought close to or separated from each other. It is also proposed to simultaneously contract and expand the volumes of the left and right working spaces formed on the outside of each diaphragm (see Patent Document 2 below).
前述した従来技術は、いずれも電磁振動式のダイヤフラムブロワー装置であるが、前者のように一つの駆動軸の両端にダイヤフラムを固定したものは、駆動軸の振動の反作用が直接ダイヤフラムを支持するケーシングに伝わるので、ケーシングの振動やこの振動による騒音が比較的大きくなるという欠点を有している。
The above-mentioned prior arts are all electromagnetic vibration type diaphragm blowers, but the one in which the diaphragms are fixed to both ends of one drive shaft like the former is a casing in which the reaction of the vibration of the drive shaft directly supports the diaphragm. Therefore, there is a drawback that the vibration of the casing and the noise due to this vibration become relatively large.
これに対して、後者のように二つの駆動軸を互いに逆向きに同期振動させるブロワー装置は、それぞれ独立して駆動される二つの駆動軸が駆動源となる電磁石に生じる反作用を打ち消すように動作することで、ダイヤフラムを支持するケーシングの振動や騒音を低減することが可能になる。また、左右のダイヤフラムの外側にそれぞれ形成される作動空間が、同時に収縮・拡大するので、２つの作動空間から吐出される空気を合わせることで大きな吐出圧を得ることができる。
On the other hand, the blower device that synchronously oscillates two drive shafts in opposite directions, like the latter, operates so that the two drive shafts that are driven independently of each other cancel the reaction that occurs in the electromagnet that is the drive source. By doing so, it becomes possible to reduce vibration and noise of the casing that supports the diaphragm. Further, since the working spaces formed on the outer sides of the left and right diaphragms simultaneously contract and expand, a large discharge pressure can be obtained by combining the air discharged from the two working spaces.
しかしながら、二つの駆動軸を持つブロワー装置は、二つの駆動軸を精度良く同軸に配置することや、正確に同期振動させることが難しく、組立調整が煩雑になる問題があり、左右のダイヤフラムの振動のバランスが崩れると、所望の低振動・低騒音や吐出圧を得ることができなくなる問題があった。
However, in a blower device having two drive shafts, it is difficult to arrange the two drive shafts coaxially with each other with high accuracy and to accurately perform synchronous vibration, and there is a problem that assembly adjustment becomes complicated. If the balance is lost, there is a problem that desired low vibration, low noise, and desired discharge pressure cannot be obtained.
特に、浄化槽の曝気用に用いられるブロワー装置は、その性質上、２４時間３６５日の稼働が求められる装置であり、高耐久性、低振動・低騒音が求められるが、後者のような二つの振動軸を持つブロワー装置を用いる場合には、精緻な組立調整が必要になっていた。
In particular, the blower device used for aeration of the septic tank is a device that is required to operate for 24 hours a day, 365 days a day due to its nature, and is required to have high durability, low vibration and low noise. When using a blower device with a vibrating shaft, precise assembly and adjustment were required.
本発明は、このような問題に対処することを課題としている。すなわち、対向した２つのダイヤフラムを同期振動させるブロワー装置において、低振動・低騒音・高吐出圧を実現するとともに、組立調整を簡易にすることで、曝気用に適したブロワー装置を提供すること、などを課題としてる。
The present invention aims to deal with such a problem. That is, in a blower device that synchronously vibrates two opposed diaphragms, low vibration, low noise, and high discharge pressure are realized, and a blower device suitable for aeration is provided by simplifying assembly adjustment.

According to the blower device with such features, low vibration, low noise and high discharge pressure can be realized, and the assembly and adjustment can be simplified. This makes it possible to provide a blower device suitable for aeration, which is required to operate 24 hours a day, 365 days a year.
以下、図面を参照して本発明の実施形態を説明する。以下の説明で、異なる図における同一符号は同一機能の部位を示しており、各図における重複説明は適宜省略する。
Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same reference numerals in different drawings indicate the parts having the same functions, and redundant description in each drawing will be appropriately omitted.
図１及び図２に示すように、ブロワー装置１は、モーター２と、偏芯回転体３と、連接部材４と、ダイヤフラム５と、ケーシング１０を備えている。モーター２は、回転する駆動軸２Ａを有しており、ベース部材６に支持されると共に、ケーシング１０に取り付けられている。
As shown in FIGS. 1 and 2, the blower device 1 includes a motor 2, an eccentric rotating body 3, a connecting member 4, a diaphragm 5, and a casing 10. The motor 2 has a rotating drive shaft 2</b>A, is supported by the base member 6 and is attached to the casing 10.
モーター２の駆動軸２Ａには、偏芯回転体３が取り付けられている。偏芯回転体３は、図５に示すように、焼結金属又はダイキャストなどで形成された一体成形物であり、回転軸となる中心位置３Ｘにモーター２の駆動軸２Ａが取り付けられる孔部３Ｐが設けられている。
The eccentric rotating body 3 is attached to the drive shaft 2A of the motor 2. As shown in FIG. 5, the eccentric rotating body 3 is an integrally formed product formed of sintered metal or die casting, and has a hole portion in which the drive shaft 2A of the motor 2 is attached to the central position 3X which is the rotating shaft. 3P is provided.
偏芯回転体３は、２つの円柱部３Ａ，３Ｂが各円柱部３Ａ，３Ｂの中心軸３ｓ，３ｔを平行に離間させた状態で一体化しており、各中心軸３ｓ，３ｔの間の中心位置３Ｘが駆動軸２Ａと同軸の回転軸になるように駆動軸２Ａに装着されている。偏芯回転体３が中心位置３Ｘである回転軸周りに回転すると、各円柱部３Ａ，３Ｂは偏芯回転することになる。
The eccentric rotating body 3 is integrated with the two cylindrical portions 3A and 3B with the central axes 3s and 3t of the cylindrical portions 3A and 3B separated in parallel, and the center between the central axes 3s and 3t. It is mounted on the drive shaft 2A so that the position 3X becomes a rotary shaft coaxial with the drive shaft 2A. When the eccentric rotating body 3 rotates about the rotation axis which is the central position 3X, the cylindrical portions 3A and 3B rotate eccentrically.
偏芯回転体３の円柱部３Ａ，３Ｂには、図４に示すように、一対の連接部材４が軸支されている。円柱部３Ａ，３Ｂの外周には、ベアリング７を介して連接部材４の一端側に設けられた取り付け孔４Ａが取り付けられている。また、連接部材４の他端側には、接続部材８を介してダイヤフラム５が接続されている。これによって、偏芯回転体３が回転軸周りに回転すると、一対の連接部材４の他端側に接続されたダイヤフラム５は、対向した状態で、互いに近接・離間するように振動する。
As shown in FIG. 4, a pair of connecting members 4 are axially supported by the cylindrical portions 3A and 3B of the eccentric rotating body 3. A mounting hole 4A provided on one end side of the connecting member 4 is attached to the outer circumferences of the columnar portions 3A and 3B via a bearing 7. The diaphragm 5 is connected to the other end of the connecting member 4 via a connecting member 8. As a result, when the eccentric rotating body 3 rotates about the rotation axis, the diaphragms 5 connected to the other end sides of the pair of connecting members 4 vibrate so as to approach and separate from each other in a facing state.
ダイヤフラム５は、その外周がケーシング１０に支持されている。また、一対のダイヤフラム５の外側には、ケーシング１０によって一対の作動空間部１０Ａが形成されている。作動空間部１０Ａは、その内部にダイヤフラム５の振動によって収縮又は拡大する一対の作動空間１０Ｓが形成されている。
The outer periphery of the diaphragm 5 is supported by the casing 10. A casing 10 forms a pair of working spaces 10A outside the pair of diaphragms 5. The working space 10A has therein a pair of working spaces 10S that contract or expand due to vibration of the diaphragm 5.
作動空間部１０Ａには、作動空間１０Ｓから空気を外に吐出する吐出弁１１と、作動空間１０Ｓに空気を引き込む吸気弁１２が設けられている。作動空間部１０Ａに設けた吐出弁１１と吸気弁１２の外側には、圧縮室１３が設けられている。圧縮室１３はベース部材６の下に設けた空気タンク１４に連通されており、空気タンク１４には排気管１５が接続されている。
The working space 10A is provided with a discharge valve 11 that discharges air from the working space 10S to the outside, and an intake valve 12 that draws air into the working space 10S. A compression chamber 13 is provided outside the discharge valve 11 and the intake valve 12 provided in the working space 10A. The compression chamber 13 communicates with an air tank 14 provided below the base member 6, and an exhaust pipe 15 is connected to the air tank 14.
このようなブロワー装置１の動作を説明する。モーター２の駆動軸２Ａを一方向に回転させると、偏芯回転体３が回転して、偏芯回転体３と連接部材４を介して連接されている一対のダイヤフラム５が、近接又は離間するように振動する。これによって、ダイヤフラム５の外側に形成されている作動空間１０Ｓは、図３（ａ）に示す排気状態と図３（ｂ）に示す吸気状態を繰り返す。
Explain the operation of such a blower device 1. When the drive shaft 2A of the motor 2 is rotated in one direction, the eccentric rotating body 3 rotates, and the pair of diaphragms 5 connected to the eccentric rotating body 3 via the connecting member 4 approach or separate. To vibrate. As a result, the working space 10S formed outside the diaphragm 5 repeats the exhaust state shown in FIG. 3(a) and the intake state shown in FIG. 3(b).
排気時には、吐出弁１１が開いて、吸気弁１２が閉じた状態になり、作動空間１０Ｓは収縮するが、吸気時には、吸気弁１２が開いて、吐出弁１１が閉じた状態になり、作動空間１０Ｓは拡大する。排気時には、作動空間１０Ｓから吐出した空気は、圧縮室１３を経由して、空気タンク１４に送られ、排気管１５から圧縮空気を吐出させる。また、吸気時には、吸気弁１２が開いて、周囲の空気が作動空間１０Ｓ内に引き込まれる。
At the time of exhaust, the discharge valve 11 is opened and the intake valve 12 is closed, and the working space 10S contracts, but at the time of intake, the intake valve 12 is opened and the discharge valve 11 is closed, and the working space is reduced. 10S expands. At the time of exhaust, the air discharged from the working space 10S is sent to the air tank 14 via the compression chamber 13, and the compressed air is discharged from the exhaust pipe 15. Further, at the time of intake, the intake valve 12 opens and the surrounding air is drawn into the working space 10S.
このようなブロワー装置１は、偏芯回転体３が一体成形物であるため、この偏芯回転体３の円柱部３Ａ，３Ｂにそれぞれ連接部材４を取り付け、偏芯回転体３をモーター２の駆動軸２Ａに取り付けるだけで、一対の連接部材４を同期振動させることができ、これに接続した一対のダイヤフラム５を互いに逆向きに同期振動させることができる。このため、ブロワー装置１は、煩雑な組立調整を行わなくても、左右のダイヤフラム５の振動バランスが崩れることは無く、同期して吸気と排気が行われる左右の作動空間１０Ｓによって、所望の低振動・低騒音を実現することができ、且つ、左右の作動空間１０Ｓから吐出される空気を合わせることで、所望の吐出圧を得ることができる。
In such a blower device 1, since the eccentric rotary body 3 is an integrally molded product, the connecting members 4 are attached to the cylindrical portions 3A and 3B of the eccentric rotary body 3, respectively, and the eccentric rotary body 3 is connected to the motor 2. Only by attaching to the drive shaft 2A, the pair of connecting members 4 can be made to synchronously vibrate, and the pair of diaphragms 5 connected thereto can be made to synchronously vibrate in opposite directions. Therefore, the blower device 1 does not lose the vibration balance of the left and right diaphragms 5 without complicated assembly and adjustment, and the left and right working spaces 10S in which the intake and the exhaust are performed in synchronism allow a desired low level. Vibration and low noise can be realized, and a desired discharge pressure can be obtained by combining the air discharged from the left and right working spaces 10S.
このように、ブロワー装置１は、一体化した偏芯回転体３を用いることで、組立調整の簡略化が可能になり、対向した２つのダイヤフラム５を同期振動させて、低振動・低騒音・高吐出圧を実現することができる。これにより、２４時間３６５日の稼働が求められる曝気用に適したブロワー装置を提供することができる。
As described above, the blower device 1 can simplify the assembly and adjustment by using the integrated eccentric rotating body 3, and synchronously vibrates the two diaphragms 5 facing each other to reduce low vibration and low noise. A high discharge pressure can be realized. As a result, it is possible to provide a blower device suitable for aeration, which is required to operate for 24 hours 365 days.
