본 고안은 오폐수의 산소용해효율을 높여 정화효율을 향상시킬 수 있도록 하기 위하여 오폐수폭기조에 공기를 주입하는 오폐수폭기조 공기주입용 에어펌프의 소음기구조에 관한 것이다.The present invention relates to a silencer structure of an air pump for a wastewater aeration tank air injection to inject air into a wastewater aeration tank to improve the oxygen dissolving efficiency of the wastewater to improve the purification efficiency.
에어펌프의 입구측과 출구측에는 흡입소음기와 토출소음기를 설치하여 에어펌프가 작동시 로우터(ROTOR)의 회전마찰에 의하여 매우 심하게 발생되는 소음을 감소시키게 되는 바,Inlet and outlet silencers are installed on the inlet and outlet sides of the air pump to reduce the noise generated by the rotational friction of the rotor when the air pump operates.
종래에는 흡입소음기 및 토출소음기의 흡입관과 토출관에다 여러개의 구멍을 뚫거나 내부에다 수개의 다공판을 설치하여 소음을 감소시키게 된 구조로 구성된 것이므로 이는 소음이 통과하는 거리가 매우 짧아 소음의 감소효율이 양호하지 못하여 소음기로서의 목적을 충분히 달성시킬 수 없는 결점이 있었다.Conventionally, it is composed of a structure that reduces the noise by drilling a plurality of holes in the suction pipe and the discharge pipe of the suction silencer and the discharge silencer or by installing a plurality of perforated plates therein. There was a defect that it was not good and could not fully achieve the purpose as a silencer.
본 고안은 상기와 같은 결점을 해결하기 위하여 흡입소음기(SUCTION SILENCER)와 토출소음기(DISCHARGE SILENCER)의 흡입관과 공기흡입구멍 및 토출관과 공기토출구멍의 사이에 태엽식으로 소음감소판을 권회하여 에어펌프의 내에서 발생되는 소음을 긴통로를 거치하여 감소시킬수 있도록 함으로서 소음의 감소효율을 대폭 향상시킬 수 있도록 한 오폐수폭기조 공기주입용 에어펌프의 소음기구조를 안출하게 된 것인데, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the above-mentioned drawbacks, the present invention winds up the noise reduction plate by winding a spring between the suction tube, the air suction hole, the discharge tube, and the air discharge hole of the suction silencer and the discharge silencer. The noise generated in the pump can be reduced through a long passage to devise a silencer structure of an air pump for wastewater aeration tank air injection, which can greatly improve the noise reduction efficiency. The explanation is as follows.
에어펌프(1)의 입구(1A)에는 걸림턱(4A)이 형성된 흡입관(4)에 패킹(5)과 카버(6A)(6B)를 씌운 흡입소음통(2')을 끼워 볼트(4B)에 너트(7)를 나사맞춤하여서 된 공기흡입소음기(2)를 연결하고,The inlet 1A of the air pump 1 is fitted with a suction pipe 4 'with a packing 5 and a cover 6A and 6B in a suction pipe 4 having a locking jaw 4A, and a bolt 4B. Connect the air intake silencer (2) by fitting the nut (7) to the
출구(1B)에는 걸림턱(4A)이 형성된 토출관(4')에 패킹(5)과 카버(6A')(6B')를 씌운 토출소음통(3')을 끼워 볼트(4B')에 너트(7)를 나사맞춤하여서 된 공기토출소음기(3)를 연결하여서 된 공지의 것에 있어서,At the outlet 1B, a discharge noise cylinder 3 'covered with a packing 5 and a cover 6A' and 6B 'is inserted into a discharge tube 4' having a locking projection 4A formed thereon, and a bolt 4B 'is provided. In the well-known thing which connected the air discharge silencer 3 made by screwing the nut 7,
흡입소음기(2)의 카버(6A)에는 여러개의 공기흡입구멍(601)을 뚫고 내부에는형의 태엽식으로 소음감소판(8)을 설치하고, 토출소음기(3)의 카버(6B')에는 여러개의 공기토출구멍(602)을 뚫고 내부에는 태엽식으로 소음감소판(8')을 설치하여서 된 것이다.Carburetor 6A of suction silencer 2 drills a plurality of air suction holes 601 therein. The wind noise reduction plate 8 is installed in the shape of a spring, and a plurality of air discharge holes 602 are drilled through the carver 6B 'of the discharge silencer 3, and the sound reduction plate 8' is installed inside the wind. It was installed.
미설명부호 9는 오폐수폭기조이고, 10은 모우터이며, 11은 로우터이다.Reference numeral 9 is a wastewater tank, 10 is a motor, and 11 is a rotor.
이와 같이 된 본고안은 에어펌프(1)의 입구(1A)에는 흡입소음기(2)의 흡입관(4)을 연결하고, 에어펌프(1)의 출구(1B)에는 토출소음기(3)의 토출관(4')을 연결하여 모우터(10)및 에어펌프(1)를 작동시키게 되면 에어펌프(1)의 흡입력에 의하여 공기흡입구멍(601)으로 흡입되는 공기는 태엽식으로 설치된 소음감소판(8)에 의하여 형성된 긴 와류상의 통로를 따라 제3도와 같이 이동하여 제2도와 같이 흡입관(4)을 통과하여 에어펌프(1)의 입구(1A)로 유입되는 것이며,In this way, the inlet 1A of the air pump 1 is connected to the suction pipe 4 of the suction silencer 2, and the discharge pipe of the discharge silencer 3 is connected to the outlet 1B of the air pump 1. When the motor 10 and the air pump 1 are operated by connecting the 4 ', the air sucked into the air suction hole 601 by the suction force of the air pump 1 is a spring-loaded noise reduction plate ( It moves along the long vortex-shaped passage formed by 8) as shown in FIG. 3 and enters the inlet 1A of the air pump 1 through the suction pipe 4 as shown in FIG.
에어펌프(1)의 출구(1B)로 배출되는 공기는 토출소음기(3)의 토출관(4')을 통하여 내부로 들어가 제6도와 같이 태엽식으로 감긴 소음감소판(8')의 내측에서 외측으로 이동하여 카버(6B')에 뚫린 공기토출구멍(602)으로 토출되어 오폐수폭기조(9)로 주입되게 되는데,The air discharged to the outlet 1B of the air pump 1 enters through the discharge pipe 4 'of the discharge silencer 3 and enters the inside of the noise reduction plate 8' wound in a winding manner as shown in FIG. It moves to the outside and is discharged to the air discharge hole 602 bored in the carver (6B ') is injected into the wastewater aeration tank (9),
이때 본원의 흡입소음기(2)의 흡입소음통(2')의 내부와 토출소음기(3)의 토출소음통(3')의 내부는 소음감소판(8)(8')을 태엽식으로 감아 긴통로를 형성하였으므로 에어펌프(1)의 내부에서 발생되는 소음은 흡입관(4)과 소음감소판(8)에 의하여 형성된 긴통로를 거쳐 공기흡입구멍(601)외방으로 흘러나오게됨과 동시에 토출관(4')및 소음감소판(8)에 의하여 형성된 긴통로를 거치면서 점차 약화되게 되므로 매우 저소음으로 감소케되는 것이다.At this time, the inside of the suction noise cylinder 2 'of the suction silencer 2 of the present application and the discharge noise cylinder 3' of the discharge silencer 3 are wound around the noise reduction plates 8 and 8 'with a winding type. Since the channel is formed, the noise generated inside the air pump 1 flows out of the air suction hole 601 through the channel formed by the suction pipe 4 and the noise reduction plate 8, and at the same time, the discharge pipe ( 4 ') and it is gradually weakened through the long path formed by the noise reduction plate (8) is to be reduced to very low noise.
이와 같은 본고안은 에어펌프(1)의 내부에서 발생되는 매우 심한 소음을 태엽식으로 감은 소음감소판(8)(8')에 의하여 형성한 긴통로를 이동되게 하여 점차 감소시키게 되므로 매우 양호한 소음감소효율을 발휘시킬 수 있는 효과가 있다.This proposal is to move the long passage formed by the noise reduction plate (8) (8 ') wound around the very severe noise generated in the interior of the air pump (1) is gradually reduced to a very good noise There is an effect that can exhibit a reduction efficiency.
