개구부(101)(102)를 형성한 세척통체(1)의 상부에 고정한 실린더(3)의 피스톤로드(301)는 세척통체(1)의 내에 위치되게하여 단부에는 구멍(201)이 뚫린 프레임(2)을 고정하여 상부에는 안내봉(4)을 고정하고,The piston rod 301 of the cylinder 3 fixed to the upper portion of the washing cylinder 1 having the openings 101 and 102 is positioned in the washing cylinder 1 so that an end portion of the frame having holes 201 is formed. 2) to fix the guide bar (4) on the top,
구멍(201)의 주위에는 수개의 롤러(6)를 축(5)으로 유착하여 구멍(701)이 뚫린 원판드럼(7)(7')을 고정하고, 원판드럼(7)에는 일정한 간격으로 여러개의 돌봉(702)을 고정하여 구멍(901)이 뚫린 원판체인스프로켓(9)을 볼트(8)로 고정하고 원판드럼(7)(7')에는 한쌍의 피세척물가이드(10)와 여러개의 피세척물안내롤러(11)를 서로 마주보게 유착한 한쌍의 브라켓트(12)를 고정하고,Several rollers 6 are bonded to the shaft 5 around the hole 201 to fix the disc drums 7 and 7 'through which the holes 701 are drilled, and to the disc drums 7 at regular intervals. To fix the bar 702 of the disc body sprocket (9) with a hole (901) through the bolt (8) and to the disc drum (7) (7 ') a pair of objects to be cleaned (10) Fixing the pair of brackets (12) adhered to each other to guide the object to be cleaned 11,
프레임(2)의 상부에 고정한 기어박스(13)의 지지관(14)에는 유압모터(15)를 고정하여 축(16)의 베벨기어(16')는 체인기어(18)가 고정된 축(17)의 베벨기어(17)와 이맞춤시켜 체인기어(18)는 원판체인스포로켓(9)과 체인(19)으로 연결하여 원판드럼(7)(7')을 회전시킬 수 있도록 하고,The hydraulic motor 15 is fixed to the support tube 14 of the gear box 13 fixed to the upper part of the frame 2 so that the bevel gear 16 ′ of the shaft 16 is the shaft on which the chain gear 18 is fixed. In combination with the bevel gear 17 of 17), the chain gear 18 is connected to the disc chain rocket 9 and the chain 19 to rotate the disc drum (7) (7 '),
세척통체(1)의 하방에는 세척수분사관(20)을 설치하여 순환관(21)과 순환펌프(22)에 의하여 노즐(20')로 세척수를 분사시킬 수 있도록 하고, 에어분사관(23)을 설치하여 에어펌프(24)에 의하여 노즐(23')로 공기를 분사시킬 수 있도록 한 것이다.A washing water spray pipe 20 is installed below the washing cylinder 1 so that the washing water can be sprayed to the nozzle 20 'by the circulation pipe 21 and the circulation pump 22, and the air spray pipe 23 is provided. It is to be installed to be able to inject air to the nozzle 23 'by the air pump 24.
미설명부호 25는 피세척물이고Unexplained number 25 is the object to be cleaned
26은 유입구이며26 is the inlet
27은 배출구이고27 is the outlet
28은 피세척물반입레일이며28 is the object to be cleaned
28'는 피세척물반출레일이다.28 'is the cleansing object removal rail.
이와 같이 된 본 고안은 이물질이 묻은 피세척물(25)을 세척코자 할 때는 피세척물반입레일(28) 위에 놓아 이동시켜 피세척물가이드(10)와 피세척물안내롤러(11) 사이에 도2 및 도3과 같이 위치시키고 실린더(3)를 작동하여 피스톤로드(301)를 하강시키면 피스톤로드(301)에 고정된 프레임(2)은 수면아래로 하강되며,The present invention, as described above, is to be placed on the object-loading rail 28 to move the object to be cleaned when cleaning the object 25 having foreign matters between the object to be cleaned 10 and the object guide roller 11. Positioning as shown in Figures 2 and 3 and operating the cylinder 3 to lower the piston rod 301, the frame 2 fixed to the piston rod 301 is lowered below the water surface,
이 때 프레임(2)은 프레임(2)의 상부에 고정된 안내봉(4)에 의하여 흔들림이 없이 매우 안정된 자세로 하강하게 된다.At this time, the frame 2 is lowered in a very stable posture without shaking by the guide rod 4 fixed to the upper part of the frame 2.
프레임(2)이 도2 및 도3의 가상선표시와 같이 수중에 위치된 상태에서 유압모터(15)를 작동하여 축(16)을 회전시키면 축(16)의 베벨기어(16')와 이맞춤된 베벨기어(17')에 의하여 축(17)및 체인기어(18)는 회전하게되며, 이와 동시에 체인기어(18)와 체인(19)으로 연결된 원판체인스프로켓(9)이 회전하게 된다.When the frame 2 is rotated by operating the hydraulic motor 15 while the frame 2 is positioned in the water as shown by the virtual line shown in FIGS. 2 and 3, the bevel gear 16 ′ of the shaft 16 and the The shaft 17 and the chain gear 18 are rotated by the fitted bevel gear 17 ', and at the same time the disc chain sprocket 9 connected to the chain gear 18 and the chain 19 is rotated.
이에 따라 원판체인스프로켓(9)에 고정되고 돌봉(702)과 볼트(8)에 의하여 고정되고 피세척물가이드(10)및 피세척물안내롤러(11)의 브라켓트(12)가 고정된 원판드럼(7)(7')은 회전하게되며, 피세척물(25)은 회전하게 되는데,Accordingly, the disc drum is fixed to the disc chain sprocket (9), fixed by the stone bar (702) and bolt (8), and the bracket 12 of the object to be cleaned guide (10) and the object guide roller (11) (7) (7 ') is rotated, and the object to be cleaned 25 is rotated,
이 때 유압모터(15)를 정,역회전시키게되면 세척효율은 양호하게 이루어지게 된다.At this time, if the hydraulic motor 15 is rotated forward and reverse, the cleaning efficiency is good.
상기의 상태에서 순환펌프(22)를 작동하여 세척분사관(20)의 노즐(20')로 세척수를 분사시킴과 동시에 에어펌프(24)에 의하여 에어분사관(23)의 노즐(23')로 공기를 분사시키게되면 정,역방향으로 요동되는 피세척물(25)에 의한 세척수의 요동과 노즐(20')로 분사되는 세척수에 의하여 강한 와류가 형성케되어 피세척물(25)의 구석구석에 끼인 이물질도 깨끗하게 씻기게됨과 동시에 에어분사관(23)의 노즐(23')로 분사되는 공기에 의하여 수중에 다량의 기포가 반복 생성 및 폭발을하게되며,In the above state, the circulating pump 22 is operated to inject the washing water into the nozzle 20 'of the washing spray pipe 20, and at the same time, the nozzle 23' of the air spray pipe 23 by the air pump 24. When the air is injected into the nozzle, strong vortices are formed by the shaking of the washing water by the washing object 25 that is shaken in the forward and reverse directions and by the washing water sprayed by the nozzle 20 '. At the same time, the foreign matters are also washed cleanly, and a large amount of bubbles are repeatedly generated and exploded in the water by the air injected into the nozzle 23 'of the air injection pipe 23.
상기의 기포의 폭발력에 의하여 피세척물(25)에 붙어 잘 분리되지않는 이물질도 용이하게 떨어지게 된다. 이에 따라 세척효율을 향상시킬 수 있다.By the explosive force of the bubble is attached to the object to be cleaned 25, foreign matters are not easily separated. Accordingly, the washing efficiency can be improved.
세척작업이 완료되면 실린더(3)를 작동하여 프레임(2)을 도2 및 도3과 같이 상승시키고 피세척물반출레일(28)을 통하여 외부로 배출시키면 된다.When the washing operation is completed, the cylinder 3 may be operated to raise the frame 2 as shown in FIGS. 2 and 3 and discharge it to the outside through the object to be cleaned rail 28.
이와 같은 본 고안은 피세척물(25)을 정,역회전시키는 것에 의한 요동과 노즐(20')로 분사하는 세척수의 분사에 의한 와류작용과 노즐(23')로 분사하는 분사공기에 의한 기포발생 및 폭발의 반복작용에 의하여 짧은시간내에 피세척물(25)을 깨끗이 세척할 수 있는 효과가 있다.This invention devises the vortex by the forward and reverse rotation of the cleansing material 25 and the vortex action by the injection of the washing water sprayed into the nozzle 20 'and the air bubbles by the sprayed air sprayed into the nozzle 23'. By repeated action of the generation and explosion there is an effect that can be cleaned to clean the cleaned object 25 in a short time.
