Description

양방향 송풍시스템{A both direction ventilated system}A both direction ventilated system

본 발명은 터널, 지하차도 등에서 공기조화 목적으로 사용되는 양방향 송풍시스템에 관한 것으로서, 특히 송풍날개의 정.역회전시 송풍효율을 일정하게 유지시키는 동시에 송풍시 발생되는 소음을 극소화시켜 정숙운전을 가능케 한 양방향 송풍시스템에 관한 것이다.The present invention relates to a two-way blowing system used for the purpose of air conditioning in tunnels, underground roads, etc., in particular, to maintain a constant blowing efficiency during forward and reverse rotation of the blades while minimizing the noise generated during the blowing to enable quiet operation. A two way blowing system.

일반적으로 송풍시스템은 터널, 지하차도, 지하철 등지에서 공기조화의 목적으로 사용되는데, 종래의 송풍시스템으로는 대한민국 특허출원 제 1993-23048호에 개제된 것이 있으며, 이의 구성은 도 1과 같이 통상의 원통체로 이루어지는 팬케이싱(1)의 양단에 각각 통상의 원통체인 사이렌서(Silencer)케이싱(2)(3)이 결합되는 것에 의해 전체 외형을 구성하고, 상기 사이렌서케이싱(2)(3)의 양단에는 각각 커버(4)(5)가 설치된 것에 있어서, 상기 팬케이싱(1)의 내부에는 상기 팬케이싱(1)의 내면에 끼워져서 고정되는 모터지지대(6)(7)가 모터(M)를 현가시키는 상태로 양단에서 고정되어 팬케이싱(1)의 정중앙에 위치되고, 상기 모터(M)의 모터축(MS)은 허브(10)에 고정되어지되 상기 허브(10)에는 다수의 임펠러 브레이드(8)가 나사결합되어 팬(9)을 구성하게 되며, 상기 싸이렌샤 케이싱(2)(3)의 내주면에는 각각 일정한 두께를 가진 내면 흡음판(11)(12)을 설치하되, 그 안쪽 중앙에는 상기 내면흡음판(11)(12)에 끼워져 고정되는 공기방향 유도익(13)(14)이 고정축(15)(16)에 고정되고, 상기 고정축(15)(16)의 외주면에는 중앙흡음판(17)(18)을 설치 고정하여 된것이다.In general, the air blowing system is used for the purpose of air conditioning in tunnels, underground roads, subways, etc. The conventional air blowing system is disclosed in the Republic of Korea Patent Application No. 1993-23048, the configuration thereof is a conventional Silencer casings 2 and 3, which are ordinary cylindrical bodies, are respectively joined to both ends of the pan casing 1 made of a cylindrical body to form an overall shape, and the silencer casing 2 and 3 Covers 4 and 5 are provided at both ends, respectively, and inside the fan casing 1, motor supports 6 and 7 which are fitted into and fixed to the inner surface of the fan casing 1 are motors M. It is fixed at both ends in the suspended state is located in the center of the pan casing (1), the motor shaft (MS) of the motor (M) is fixed to the hub 10, the hub 10 has a plurality of impeller braid (8) is screwed to form a fan (9), the cover On the inner circumferential surface of the lancer casing (2) (3), each of the inner sound absorbing plate (11) (12) having a predetermined thickness is installed, the inner direction of the air induction vane (13) is fitted to the inner sound absorbing plate (11) (12) (14) is fixed to the fixed shaft (15, 16), and the outer circumferential surface of the fixed shaft (15, 16) is to install and fix the central sound absorbing plate (17) (18).

그러나, 상기와 같이 구성된 종래의 송풍시스템은 모터(M)의 일측으로 돌출된 모터축(MS)에 팬(9)이 설치되어 있기 때문에 상기 모터(M)를 정역회전시켰을 때 양측의 싸이렌샤 케이싱(2)(3)으로 송풍되는 공기량이 현저하게 차이가 나게 된다.However, in the conventional blower system configured as described above, since the fan 9 is installed on the motor shaft MS protruding to one side of the motor M, the two silencer casings are rotated when the motor M is rotated forward and backward. The amount of air blown into (2) and (3) is remarkably different.

즉, 모터(M)가 정회전하여 도면상에서 좌측에 위치한 싸이렌샤 케이싱(2)으로 공기가 송출될 시에는 소망하는 공기량이 송출되는 반면, 모터(M)가 역회전하여 도면상에서 우측에 위치한 싸이렌샤 케이싱(3)으로 공기가 송출될 시에는 공기가 모터(M)의 간섭으로 인하여 송출되는 공기량이 적어짐은 물론이고, 일측으로 설치된 팬(9)에 의해 모터(M)의 진동이 큰 동시에 팬(9)의 구동력이 커 많은 에너지가 소비되는 등의 문제점이 있었다.That is, when the motor M rotates forward and air is sent to the sirensha casing 2 located on the left side in the drawing, a desired amount of air is sent out, while the motor M rotates in reverse and the sirensha located on the right side in the drawing. When the air is sent to the casing (3), the amount of air that is sent out due to the interference of the motor (M) is reduced, as well as the vibration of the motor (M) is large due to the fan (9) installed on one side of the fan ( The driving force of 9) is large and a lot of energy is consumed.

또한, 종래의 송풍시스템은 상기 싸이렌샤 케이싱(2)(3)의 내주면에 내면 흡음판(11)(12) 및 공기방향 유도익(13)(14)이 설치된 고정축(15)(16), 그리고 상기 고정축(15)(16)의 외주면에 설치되는 중앙흡음판(17)(18) 등이 구비되어 있기 때문에 이들이 공기의 흐름을 방해하여 오히려 소음을 증폭시키는 요인이 되었으며, 상기 팬케이싱(1)의 양단에 싸이렌샤 케이싱(2)(3)이 직각으로 확관되어 있기 때문에 팬케이싱(1)에서 싸이렌샤 케이싱(2)(3)으로 공급되는 공기가 순간적으로 확산되면서 소음이 발생하게 되는 등의 문제점이 있었다.In addition, the conventional blower system includes a fixed shaft (15) (16) provided with inner sound absorbing plates (11) (12) and air guiding vanes (13) (14) on an inner circumferential surface of the sirensha casing (2) (3), and Since the central sound absorbing plate (17) (18), etc. are provided on the outer circumferential surface of the fixed shaft (15, 16), such as to interfere with the flow of air rather than to amplify the noise, the fan casing (1) Since the silencer casing (2) (3) is extended at right angles to both ends of the air, the air supplied from the fan casing (1) to the silencer casing (2) (3) is instantaneously diffused and noise is generated. There was a problem.

따라서, 본 발명은 상기와 같은 문제점을 감안하여 발명한 것으로서, 회전자 케이싱에 날개을 설치하여 회전을 균일하게 하는 동시에 기계적 진동 및 소음을 극소화시키는 한편, 회전자 케이싱의 회전으로 기존 모터의 구성요소인 허브가 없어지고, 회전자 케이싱에 팬이 직접 설치됨에 따라 구동력도 작게들며, 고속회전에 따르는 플라이 휠(FLY WHEEL)효과가 증대되어 효율특성과 진동특성이 크게 향상되는 양방향 송풍시스템을 제공함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above problems, by installing a blade in the rotor casing to uniformly rotate and minimize mechanical vibration and noise, while rotating the rotor casing is a component of the existing motor The hub is eliminated, and as the fan is directly installed on the rotor casing, the driving force is also reduced, and the flywheel (FLY WHEEL) effect of the high-speed rotation is increased to provide a two-way blowing system that greatly improves the efficiency characteristics and vibration characteristics. There is a purpose.

또한, 본 발명은 싸이렌샤 케이싱의 내주면에 소정의 간극을 두고 내면흡음관을 설치하고, 이들 사이에 흡음부재를 설치하는 한편, 상기 싸이렌샤 케이싱의 내주면과 내면흡음관 사이에 이들을 이등분할 수 있는 소음차단벽을 설치하여 공기흐름에 의한 간섭을 극소화시켜 소음을 크게 줄이는 한편, 팬케이싱과 싸이렌샤 케이싱의 사이에 유량조절 댐퍼장치를 설치하는 동시에 상기 팬케이싱에서 싸이렌샤 케이싱으로 자연스럽게 확관되도록 하여 공기의 흐름을 부드럽게 하고, 또한 싸이렌샤 케이싱의 각 단부에 소정의 곡률상태로 확관되는 벨마우스를 설치하여 공기의 흐름을 부드럽게 한 양방향 송풍시스템을 제공함에 그 목적이 있다.The present invention also provides an inner sound absorbing tube with a predetermined gap on the inner circumferential surface of the silencer casing, and a sound absorbing member is provided therebetween, while dividing them between the inner circumferential surface of the silencer casing and the inner sound absorbing tube. By installing a noise barrier to minimize the interference caused by air flow, the noise is greatly reduced, while a flow control damper device is installed between the fan casing and the sirens casing, and the air is naturally expanded from the pan casing to the sirens casing. The purpose of the present invention is to provide a two-way air blowing system that softens the flow of air by installing a bell mouse that extends in a predetermined curvature state at each end of the sirensha casing.

이하, 본 발명의 바람직한 일실시예를 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 양방향 송풍시스템의 개략적인 구성도이고, 도 3은 도 2의 단면도이다.2 is a schematic configuration diagram of a two-way air blowing system according to the present invention, Figure 3 is a cross-sectional view of FIG.

먼저, 원통형상의 팬케이싱(110)의 내부에는 정.역회전이 가능도록 모터 (111)가 정중앙부에 설치되는데, 상기 모터(111)는 회전자 케이싱(112)dl 회전되는 것으로 상기 회전자 케이싱(112)의 외주부에 다수의 팬(113)rk 고정 설치되며, 상기 회전자 케이싱(112)의 양단으로 돌출된 지지축(114)이 십자형 허브(115)에 설치된다.First, the inside of the cylindrical fan casing 110, the motor 111 is installed in the center of the center so that forward and reverse rotation, the motor 111 is the rotor casing 112 dl is rotated the rotor casing A plurality of fans 113 rk are fixedly installed on an outer circumference of the 112, and support shafts 114 protruding from both ends of the rotor casing 112 are installed in the cross hub 115.

상기 팬케이싱(110)의 양 단부에 설치되는 흡.배기용 풍량조절 베인(120)은 도 4와 같이 나팔관형상으로 일측의 조작수단(122)에 의해 다수의 날개(123)를 조절하여 공기의 유량을 조절하는 유량조절 댐퍼장치(121)가 설치된다. 이때, 상기 흡.배기용 풍량조절 베인(120)은 그 내주면이 벤츄리방식으로 형성되어 있기 때문에 흡기시에는 충돌없이 팬케이싱(110)으로 공기를 유도하게 되며, 배기시에는 팬(113)에 의해 발생된 공기의 흐름을 부드럽게 하여 와류로 인한 공기손실 및 소음을 극소화시킨다.Intake and exhaust air volume control vanes 120 are installed at both ends of the fan casing 110 is a trumpet tube shape as shown in Figure 4 by adjusting the plurality of wings 123 by one operation means 122 of the air Flow control damper device 121 for adjusting the flow rate is installed. At this time, since the inner circumferential surface of the intake / exhaust air volume control vane 120 is formed in a venturi method, air is guided to the fan casing 110 without collision during intake, and is exhausted by the fan 113 during exhaust. Softens the flow of air generated, minimizing air loss and noise caused by vortices.

또한, 상기 유량조절 댐퍼장치(121)의 조작수단(122)을 수동으로 조작하여도 무방하나 모터와 같은 구동수단을 이용하여 조정될 수 있도록 함이 바람직하다.In addition, although it is possible to manually operate the operation means 122 of the flow control damper device 121, it is preferable to be adjusted using a driving means such as a motor.

상기 가이드 밴(120)의 양 단부에 각각 설치되는 싸이렌샤 케이싱(130)은 도 3과 같이 그 내주면에 소정의 간극을 두고 다수의 통기공(132)이 구비된 내면흡음관(131)이 설치되고, 상기 싸이렌샤 케이싱(130)의 내주면과 내면흡음관(131)의 사이에 흡음부재(133)가 충진되는 한편, 상기 싸이렌샤 케이싱(130)의 내주면과 내면흡음관(131) 사이에 이들을 이등분하여 소음이 전달되는 것을 방지할 수 있는 소음차단벽(134)이 설치된다.The sirensha casing 130 is installed at both ends of the guide van 120, respectively, as shown in FIG. The sound absorbing member 133 is filled between the inner circumferential surface of the sirensha casing 130 and the inner surface sound absorbing tube 131, while the sound absorbing member 133 is filled between the inner circumferential surface of the sirensha casing 130 and the inner sound absorbing tube 131. A noise blocking wall 134 is installed to bisect and prevent noise from being transmitted.

상기 싸이렌샤 케이싱(130)의 각 단부에 설치되는 흡배기용 벨마우스(140)는 역시 나팔관 형상으로서 공기의 흡.배기를 원활하게 하는데, 이 역시 풍량조절 베인(120)과 마찬가지로 흡기 시에는 충돌없이 팬케이싱(110)으로 공기를 유도하게 되며, 배기 시에는 팬(113)에 의해 발생된 공기의 흐름을 부드럽게 하여 와류로 인한 소음을 극소화시킨다.The bell mouth 140 for the intake and exhaust air ventilator 140 installed at each end of the sirensha casing 130 also has the shape of a fallopian tube, which smoothly intakes and exhausts the air, and like air flow control vanes 120, there is no collision during intake. The air is guided to the fan casing 110, and when exhausted, the air flow generated by the fan 113 is smoothed to minimize noise due to eddy currents.

상기와 같이 구성된 양방향 송풍시스템의 작용을 설명하면 다음과 같다.Referring to the operation of the bi-directional blowing system configured as described above are as follows.

먼저, 도 2와 같이 유량조절 댐퍼장치(121)의 조작수단(122)을 조작하여 날개(123)를 적당히 개방한 다음, 팬케이싱(110)의 내부에 설치되어진 모터(111)를 일방향으로 구동하게 되는데, 이와 동시에 회전자 케이싱(112)가 회전하여 그 외주부에 설치된 다수의 팬(113)을 구동하게 된다. 이때, 상기 팬(113)이 회전자 케이싱(112)에 설치되어 있기 때문에 이의 회전을 균일하게 하는 동시에 기계적 진동 및 소음을 극소화시킴은 물론, 회전자 케이싱(112)에 팬(113)이 직접 설치됨에 따라 구동력도 작게들며, 고속회전에 따르는 플라이 휠 효과가 증대되어 효율특성과 진동특성이 크게 향상된다.First, as shown in FIG. 2, by operating the operation means 122 of the flow control damper device 121, the wings 123 are properly opened, and then the motor 111 installed in the fan casing 110 is driven in one direction. At the same time, the rotor casing 112 is rotated to drive a plurality of fans 113 installed at the outer circumference thereof. At this time, since the fan 113 is installed in the rotor casing 112, the rotation of the fan 113 is uniform and the mechanical vibration and noise are minimized, as well as the fan 113 is directly installed in the rotor casing 112. As a result, the driving force is also reduced, and the flywheel effect due to the high speed rotation is increased, thereby greatly improving the efficiency characteristics and vibration characteristics.

상기 팬(113)이 구동하게 되면 도면상에서 좌측으로 공기를 송출하게 되며, 팬케이싱(110)으로부터 풍량조절 베인(120)은 회전자 회전에 의해 발생하는 와류유동을 정류시켜 유동특성을 축류운동으로 싸이렌샤 케이싱(130)으로 송출되는데, 상기 싸이렌샤 케이싱(130)의 내경이 팬케이싱(110)의 내경보다 다소 넓게 형성되어 있으므로 팬케이싱(110)을 통한 공기가 싸이렌샤 케이싱(130)의 내부에 확산되면서 송출되며, 이때 팬케이싱(110)과 싸이렌샤 케이싱(130)에서 발생되는 소음은 내면흡음관(131)의 통기공(132)으로 흡입되면서 일차 저감된 다음, 싸이렌샤 케이싱(130)과 내면흡음관(131)의 사이에 설치되어진 흡음부재(133)에서 다시 제거되고, 이로 흡입된 소음은 소음차단벽(134)에 막혀 완전히 소멸된다.When the fan 113 is driven to send air to the left in the drawing, the air flow control vane 120 from the fan casing 110 rectifies the vortex flow generated by the rotor rotation to convert the flow characteristics into axial flow It is sent to the sirensha casing 130, since the inner diameter of the sirensha casing 130 is formed slightly wider than the inner diameter of the pan casing 110, the air through the pan casing 110 is inside the sirensha casing 130. While being diffused to and sent out, the noise generated in the fan casing 110 and the sirensha casing 130 is first reduced while being sucked into the vent hole 132 of the inner sound absorbing tube 131, then the sirensha casing 130 And is removed again from the sound absorbing member 133 installed between the inner surface sound absorbing tube 131, and the noise sucked by the block is completely blocked by the noise blocking wall 134.

따라서, 본 발명은 회전자 케이싱(112)에 팬(113)을 설치하여 회전을 균일하게 하는 동시에 기계적 진동 및 소음을 극소화시키는 한편, 회전자 케이싱(112)의 회전으로 기존 송풍기의 구성요소인 허브가 없어지고, 회전자 케이싱(112)에 팬(113)이 직접 설치됨에 따라 초기 구동력은 다소 커지지만, 고속회전에 따르는 플라이 휠의 효과가 증대되어 효율특성과 진동특성이 크게 향상되는 효과가 있다.Accordingly, the present invention installs a fan 113 in the rotor casing 112 to uniformly rotate and minimize mechanical vibration and noise, while the rotor casing 112 rotates the hub which is a component of the existing blower. The initial driving force is slightly increased as the fan 113 is directly installed on the rotor casing 112, but the effect of the flywheel according to the high speed rotation is increased, so that the efficiency characteristics and vibration characteristics are greatly improved. .

또한, 본 발명은 싸이렌샤 케이싱(130)의 내주면에 공명관을 두고 내면흡음관(131)을 설치하고, 이들 사이에 흡음부재(133)를 설치하는 한편, 상기 싸이렌샤 케이싱(130)의 내주면과 내면흡음관(131) 사이에 이들을 이등분할 수 있는 소음차단벽(134)을 설치하여 공기흐름에 의한 간섭을 극소화시켜 소음을 크게 줄이는 한편, 팬케이싱(110)과 싸이렌샤 케이싱(130)의 사이에 유량조절 댐퍼장치(121)를 설치하는 동시에 상기 팬케이싱(110)에서 싸이렌샤 케이싱(130)으로 자연스럽게 확관되도록 하여 공기의 흐름을 부드럽게 하고, 또한 싸이렌샤 케이싱(130)의 각 단부에 소정의 곡률상태로 확관되는 벨마우스(140)를 설치하여 공기의 흐름을 부드럽게 한 매우 유용한 효과가 있다.In addition, the present invention provides a sound absorbing tube 131 with a resonance tube on the inner circumferential surface of the sirensha casing 130, the sound absorbing member 133 is provided between them, and the inner circumferential surface of the sirensha casing 130 and A noise blocking wall 134 is provided between the inner sound absorbing pipe 131 to minimize the interference caused by the air flow, thereby greatly reducing the noise, and between the fan casing 110 and the silencer casing 130. At the same time, the flow control damper device 121 is installed at the same time, so that the air flows naturally from the fan casing 110 to the sirens casing 130 so as to smooth the flow of air, and at each end of the sirens casing 130. By installing the bell mouse 140 which is expanded in a curvature state, there is a very useful effect of softening the flow of air.
