Description
본 발명은 슬러지 탈수기에서 컨베이어벨트와 같이 설치되어 순환되면서 슬러지를 걸러주는 여과포의 세척장치에 관한 것으로서 특히 여과포의 세척효율을 최대한 높여줄 수 있도록 한 발명에 관한 것이다.The present invention relates to a washing device for filtering the filter cloth to filter the sludge while being installed and circulated like a conveyor belt in the sludge dehydrator, and more particularly, to an invention to increase the cleaning efficiency of the filter cloth to the maximum.
일반적으로 폐수처리장에서 발생되는 슬러지는 롤러(roller)들 사이에서 컨베이어벨트 식으로 설치된 여과포에 의하여 폐수에 함유된 슬러지들이 여과되는 시스템으로 되어 있다.In general, the sludge generated in the wastewater treatment plant is a system in which the sludge contained in the wastewater is filtered by a filter cloth installed in a conveyor belt between rollers.
이와 같이 여과포에 걸러진 슬러지들은 케이크 상태로 배출되고, 여과포의 눈목 사이에 끼워진 슬러지들은 그 상부에 장착된 분사관의 노즐을 통해 분사되는 물에 의하여 여과포가 세척되면서 슬러지들이 제거되는 시스템으로 되어 있다.As such, the sludge filtered by the filter cloth is discharged in a cake state, and the sludge sandwiched between the eyelets of the filter cloth is a system in which the sludge is removed while the filter cloth is washed by the water sprayed through the nozzle of the injection tube mounted on the upper portion thereof.
그러나, 전술한 세척장치는 슬러지 탈수기의 설치규정이나 전체적인 장치의 안전도 등을 감안하여 펌프의 압력을 무한정 높여줄 수 없는 것이므로 펌프에 의하여 분사되는 순수한 수압의 힘만으로는 효과적으로 슬러지를 제거할 수 없었고 많은 양의 세척용수가 소요되는 등의 폐단이 발생되었다.However, the above-mentioned washing apparatus cannot raise the pressure of the pump indefinitely in consideration of the installation regulations of the sludge dehydrator or the overall safety of the apparatus, and thus, the pure water pressure sprayed by the pump alone cannot effectively remove the sludge. Closure occurred, such as the consumption of a large amount of washing water.
또한, 슬러지를 제거한 세척용수는 용수에 포함된 슬러지를 여과 처리한 후 재사용되는 것이므로 세척용수에는 상당한 찌꺼기가 남아있고 이와 같은 찌꺼기는 세척용수의 분사시 분사관의 노즐을 막히게하므로 세척효율이 현저하게 저하되는 등의 폐단이 있었다.In addition, since the sludge-washing water is reused after the sludge contained in the water is filtered and the sludge remains in the washing water, a considerable amount of residue remains. Such a residue clogs the nozzle of the injection pipe when spraying the washing water. There was a closure such as deterioration.
그리고, 노즐을 청소하기 위해서는 분사관의 일측을 분리시킨 후 그 내부에 청소용 솔을 삽입시켜 막힌 노즐을 청소해야하므로 노즐의 청소작업이 상당히 번거롭고 일시적으로 급수용 펌프의 구동을 정지시켜야 하는 등의 문제점이 있었다.In addition, in order to clean the nozzle, one side of the injection pipe must be separated and a cleaning brush must be inserted therein to clean the clogged nozzle. Therefore, the cleaning work of the nozzle is quite cumbersome and the operation of the water supply pump must be temporarily stopped. There was this.
본 발명은 상기한 문제점을 감안하여 창안한 것으로서, 그 목적은 노즐의 청소 작업이 필요 없고, 세척의 효율을 극대화시킬 수 있는 슬러지 탈수기용 여과포 세척장치를 제공함에 있는 것이다.The present invention has been made in view of the above-described problems, and its object is to provide a sludge dehydrator filter cloth cleaning device capable of maximizing the cleaning efficiency without the need for cleaning the nozzle.

이하, 상기한 목적을 달성하기 위한 바람직한 본 발명의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object is as follows.
도 1 내지는 도 4에서 도시한 바와 같이, 일방향으로 길게 형성된 물분사관(10)의 하부에는 복수개의 노즐(11)들이 장착되어 있고, 물분사관(10)의 일측에는 세척용수 급수용 펌프(13)와 접속되는 호스(12)가 설치되어 있다.1 to 4, a plurality of nozzles 11 are mounted on the lower portion of the water spray pipe 10 formed in one direction, and the pump 13 for washing water feed water is provided on one side of the water spray pipe 10. The hose 12 connected with the is provided.
상기 물분사관(10)의 하부에는 롤러에 권회되어 순환되는 여과포(40)가 설치되어 일정속도로 이송된다.The lower portion of the water spray pipe 10 is provided with a filter cloth (40) which is wound and circulated by a roller is transported at a constant speed.
따라서, 급수용 펌프(13)에서 압송된 세척용수가 물분사관(10)의 노즐(11)을 통해 여과포(40)에 분사되어 슬러지를 제거할 수 있도록 되어 있다.Therefore, the washing water pumped by the water feed pump 13 is sprayed onto the filter cloth 40 through the nozzle 11 of the water spray pipe 10 so as to remove sludge.
물론, 전술한 구성으로 이루어진 여과포(40) 세척장치는 이미 알려진 공지의 사실이다. 그러나 본 발명의 구성에 있어서 가장 중요한 특징은 상기 물분사관(10)의 내부에 공기분사관(20)이 삽입되고, 물분사관(10)이 소정의 반경 이내에서 회전되도록 함에 있는 것이다.Of course, the filter cloth 40 cleaning device made of the above-described configuration is a known fact already known. However, the most important feature in the configuration of the present invention is that the air spray pipe 20 is inserted into the water spray pipe 10 so that the water spray pipe 10 rotates within a predetermined radius.
즉, 상기 물분사관(10)의 내부에는 공기압축펌프(23)와 접속되는 공기분사관(20)이 설치되어 있고, 공기분사관(20)의 하부에도 복수개의 노즐(21)들이 장착되어 있다.That is, the air spray pipe 20 connected to the air compression pump 23 is installed in the water spray pipe 10, and the plurality of nozzles 21 are also mounted below the air spray pipe 20. .
상기 공기분사관(20)의 노즐(21)들은 물분사관(10)의 노즐(11)들의 직상부에 위치되어 있고, 공기분사관(20)의 노즐(21)에 뚫려진 구멍은 물분사관(10)의 노즐(11)에 뚫려진 구멍 보다 작게 형성된다.The nozzles 21 of the air injection pipe 20 are located directly above the nozzles 11 of the water injection pipe 10, and the hole drilled in the nozzle 21 of the air injection pipe 20 is a water injection pipe ( It is formed smaller than the hole drilled in the nozzle 11 of 10).
따라서, 물분사관(10) 내부에 유입된 세척용수가 노즐(11)을 통해 분사될 때 공기분사관(20)의 노즐(21)을 통해 분사되는 압축공기가 물분사관(10)의 노즐(11) 내부로 분사되는 것이므로 세척용수의 분사력이 상승되면서도 넓게 확산되면서 분사되는 것으로서 여과포(40)의 세척효율을 최대한 높여줄 수 있는 동시에 물분사관(10)의 노즐(11)이 막히는 등의 폐단을 효과적으로 방지할 수 있는 것이다.Therefore, when the washing water introduced into the water spray pipe 10 is sprayed through the nozzle 11, the compressed air sprayed through the nozzle 21 of the air spray pipe 20 is nozzle 11 of the water spray pipe 10. As it is injected into the inside, the spraying power of the washing water is widely spread while being sprayed to increase the washing efficiency of the filter cloth 40 to the maximum, and at the same time, the nozzle 11 of the water spray pipe 10 is blocked effectively. It can be prevented.
한편, 상기 공기분사관(20)과 공기압축펌프(23) 사이에 연결된 호스(22)에는 타이머(24a)에 의하여 작동되는 전자밸브(24)가 장착되어 간헐적으로 압축공기를 분사시킬 수도 있는 것으로 보다 다양하게 사용할 수 있는 등의 이점이 있다.On the other hand, the hose 22 connected between the air injection pipe 20 and the air compression pump 23 is equipped with an solenoid valve 24 operated by a timer 24a to intermittently inject compressed air. There are advantages such as being more versatile.
또한, 상기 물분사관(10)은 소정의 반경 내에서 회동되면서 세척의 효율을 더욱 높일 수 있도록 되어 있다.In addition, the water spray pipe 10 is rotated within a predetermined radius to further increase the efficiency of the washing.
즉, 상기 물분사관(10)의 양측에는 지지용 베어링(33)이 장착되어 물분사관(10)이 안정적으로 회동될 수 있도록 되어 있다.That is, support bearings 33 are mounted on both sides of the water spray pipe 10 so that the water spray pipe 10 can be rotated stably.
상기 물분사관(10)의 일측에는 피니언(30)이 장착되어 있고, 왕복 이동되는 래크(31)에 치합되어 물분사관(10)이 소정의 각 범위 내에서 회동될 수 있도록 되어 있다.One side of the water spray pipe 10 is mounted with a pinion 30, is engaged with the rack 31 to be reciprocated so that the water spray pipe 10 can be rotated within a predetermined range.
상기 래크(31)를 왕복 이동시키는 구동수단(32)은 공압이나 유압으로 작동되는 실린더(32a)에서 출몰되는 피스톤로드에 래크(31)가 고정되어 이동되는 구성으로 되어 있다.The drive means 32 for reciprocating the rack 31 has a configuration in which the rack 31 is fixed to the piston rod which is spouted from the cylinder 32a operated by pneumatic or hydraulic pressure.
물론, 도시하지는 않았지만 상기 구동수단(32)은 캠 장치나 감속기어장치 등을 사용하여도 무방한 것으로서 본 발명에 의한 구동수단(32)은 꼭 실린더(32a)에 한정되는 것은 아니다.Of course, although not shown, the driving means 32 may be a cam device, a reduction gear device, or the like, and the driving means 32 according to the present invention is not necessarily limited to the cylinder 32a.
이와 같이 물분사관(10)이 소정의 반경 이내에서 회동되도록 구성하면 물분사관(10)의 노즐(11)을 통해 압축공기와 함께 분사되는 세척용수가 여과포에 접촉되는 면적이 넓어지면서도 접촉되는 시간을 연장시킬 수 있는 동시에 다양한 경사각을 이루면서 분사되는 것이므로 여과포(40)의 눈목 사이에 끼여진 슬러지들이 효과적으로 제거되는 등의 이점이 있다.As such, when the water spray pipe 10 is configured to rotate within a predetermined radius, the time for which the washing water sprayed with the compressed air through the nozzle 11 of the water spray pipe 10 is in contact with the filter cloth while the area of contact with the filter cloth becomes wider. At the same time it is to be sprayed while forming a variety of inclination angle, there is an advantage such that sludge sandwiched between the eyes of the filter cloth 40 is effectively removed.
따라서, 단위 길이당 세척수의 분사시간 및 분사각이 넓어지고, 분사력이 높아지는 것이므로 전체적인 분사용 노즐의 수량을 줄일 수 있고, 세척수의 사용량을 절감시킬 수 있는 등의 이점이 있다.Therefore, since the injection time and the injection angle of the washing water per unit length is widened, and the spraying force is increased, the total number of nozzles for spraying can be reduced, and the amount of washing water can be reduced.
이상에서 상술한 바와 같은 본 발명은, 물분사관(10)의 내부에공기분사관(20)이 삽입되고, 물분사관(10)이 소정의 반경 이내에서 회전되는 여과포 세척장치를 구성함으로써, 상기 물분사관(10)의 노즐(11)을 통해 압축공기와 함께 분사되는 세척용수가 여과포(40)에 접촉되는 시간을 길게하여 세척효율을 높여줄 수 있는 동시에 다양한 경사각을 이루면서 분사됨에 따라 여과포(40)의 눈목 사이에 끼여진 슬러지들이 효과적으로 제거되는 이점이 있고, 특히 압축공기에 의하여 물분사관(10)의 노즐(11)이 막혀지는 폐단을 효과적으로 방지할 수 있는 것으로서 종래의 제반 문제점들이 완벽하게 해소됨에 따라 여과포 세척장치의 대외 경쟁력을 최대한 높여줄 수 있는 것이다.According to the present invention as described above, the water spray pipe 20 is inserted into the water spray pipe 10, the water spray pipe 10 is configured by the filter cloth cleaning device is rotated within a predetermined radius, the water powder The washing water sprayed with the compressed air through the nozzle 11 of the yarn pipe 10 may increase the washing time by increasing the contact time with the filter cloth 40, and at the same time, spraying the filter cloth 40 while forming various inclination angles. The sludge sandwiched between the eyes of the eye is effectively removed, and in particular, since it is possible to effectively prevent the closed end of the nozzle 11 of the water spray pipe 10 due to the compressed air, all the conventional problems are completely solved. Therefore, it is possible to increase the external competitiveness of the filter cloth cleaning device as much as possible.
