Description
본 발명은 슬러지 펌핑용 양수기에 관한 것으로, 특히 슬러지를 파쇄하고, 분쇄하기 위한 크러셔(crusher)가 부설되어 분쇄된 슬러지를 물 과함께 펌핑할 수 있는 양수기에 관한 것이다.The present invention relates to a pump for sludge pumping, and more particularly, to a pump for pumping sludge crushed with water by crusher (crusher) for crushing and crushing the sludge.
슬러지(sludge)는 물이나 기름 등에 혼합된 불순물을 일컫는 것으로, 특히 화학공장등에서는 용기 등에 침전되어 있던 고형(固形)의 슬러지를 제거하기 위해 대용량 양수기를 사용하여 슬러지와 함께 물 또는 기름, 화공약품(이를 액체라 총칭하기로 한다)을 펌핑하기도 하는데, 양수기가 감당하기 힘든 크기의 슬러지가 양수기에 흡입되는 경우는 양수기의 작동을 멈추게 하고, 고장의 원인이 되기도 한다.Sludge refers to impurities mixed with water, oil, etc. Especially in chemical plants, sludge is used to remove solid sludge that has settled in containers. It is also pumped (we will refer to this collectively as a liquid). If the sludge is sucked into the pump, it may cause the pump to stop working and cause a breakdown.
또한 고형의 슬러지가 액체와 함께 배출되므로 엄청난 토출력을 필요로 하게 되어 토출되는 액체량에 비해서 훨씬 큰 용량의 양수기를 사용하여야 하므로 큰 낭비의 요소를 갖는 것이다.In addition, since the solid sludge is discharged together with the liquid, it requires tremendous earth output, which requires a much larger amount of water pump than the amount of liquid discharged.
따라서 양수기의 일측에 양수기와 별도로 크러셔(crusher)를 장착하고, 상기 크러셔에 의해 먼저 슬러지를 분쇄한 다음, 분쇄된 슬러지와 액체를 양수기로 보내 양수기에 의해 펌핑되도록 하는 방법을 사용하기도 하는데, 이는 슬러지만 걸러서 분쇄하므로 미세한 분쇄가 곤란하고, 슬러지의 크기에 따른 순차적인 분쇄가 곤란하며, 잘 막히고, 흡입배출력이 약한 폐단을 갖는 것이다.Therefore, a crusher is mounted on one side of the water pump separately from the water pump, and the sludge is first crushed by the crusher, and then the crushed sludge and liquid are sent to the water pump to be pumped by the water pump. It is difficult to pulverize finely, so it is difficult to sequential pulverization according to the size of the sludge, clogged well, and has a closed end with weak suction power.
따라서 본 발명은 상기와 같은 폐단을 해결하기 위해 안출된 것으로, 흡입구와 토출구가 형성되고, 동력전달부로 부터 회전력을 전달받는 축을 구비하는 양수기에 있어서 상기 양수기의 본체에 다수개의 통공이 천공된 원통형의 분쇄망체를 장착하고, 상기 축에는 슬러지의 미세한 분쇄를 위한 분쇄용 칼날을 구비하는 임펠러와 슬러지의 조대(粗大)한 분쇄를 위한 파쇄용 칼날을 장착한 구성을 갖는 것이다.Therefore, the present invention is devised to solve the above-mentioned closed end, the inlet and discharge port is formed, and in the water pump having a shaft that receives the rotational force from the power transmission unit of the cylindrical of the plurality of holes perforated in the body of the water pump The grinding mesh is mounted, and the shaft is equipped with an impeller having a grinding blade for fine grinding of the sludge and a grinding blade for coarse grinding of the sludge.
본 발명의 또 다른 목적은 본 발명에 있어서 슬러지를 미세하게 분쇄할 수 있는 새로운 구조의 임펠러를 제공하기 위한 것이다.Still another object of the present invention is to provide an impeller having a novel structure capable of finely crushing sludge in the present invention.
본 발명의 또 다른 목적은 상기 임펠러에 슬러지의 미세한 분쇄를 위해 형성한 분쇄용 칼날을 교환할 수 있도록 구성한 것이다.Another object of the present invention is configured to be able to replace the grinding blade formed for the fine grinding of the sludge in the impeller.
본 발명의 또 다른 목적은 임펠러의 후방에 또하나의 임펠러를 형성하여 축과 본체의 틈 사이로 액체가 새나가지 않고 펌핑능력을 향상시킬 수 있도록 구성한 것이다.Another object of the present invention is to form another impeller to the rear of the impeller is configured to improve the pumping capacity without leaking liquid between the gap between the shaft and the body.

본 발명을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.
본 발명은 크게 흡입구(21)와 토출구(11)가 형성되고, 동력전달부(14)로 부터 회전력을 전달받아 회전하는 축(12)을 구비하는 공지의 양수기에 있어서 상기 양수기의 본체(10) 내부에 장착되는 다수개의 통공(41)이 천공된 원통형의 분쇄망체(40)와, 상기 축(12)에 축착되는 슬러지의 미세한 분쇄를 위한 분쇄용 칼날(51d)을 구비하는 임펠러(50)와, 슬러지의 조대(粗大)한 분쇄를 위한 파쇄용 칼날(60)로 이루어진 것이다.The present invention is largely formed in the inlet port 21 and the discharge port 11, the main body 10 of the water pump in a known water pump having a shaft 12 that rotates by receiving a rotation force from the power transmission unit 14 An impeller 50 having a cylindrical grinding net 40 perforated with a plurality of through holes 41 mounted therein, and a grinding blade 51d for fine grinding of sludge adhered to the shaft 12; , It consists of a shredding blade 60 for coarse grinding of sludge.
본 발명 양수기(1)는 동력전달부(14)와 축(12) 사이에 형성되어 축(12)을 지지하기 위한 베어링 하우징(13)을 구비할 수도 있다.The water pump 1 of the present invention may have a bearing housing 13 formed between the power transmission unit 14 and the shaft 12 to support the shaft 12.
상기 분쇄망(40)는 다수개의 통공(41)이 천공된 원통체(42)와, 상기 원통체(42)의 끝단에 형성되어 볼트(43)에 의해 본체(10)에 체결되기 위한 결합턱(44)이 형성된 것이다.The grinding net 40 has a cylindrical body 42 in which a plurality of through-holes 41 are drilled, and is formed at the end of the cylindrical body 42 to be coupled to the main body 10 by bolts 43. (44) is formed.
상기 임펠러(50)는 본 발명에 있어서 매우 중요한 구성으로 흡입구(21)를 통해 유입된 고형의 슬러지가 파쇄용 칼날(60)에 의해 일차 파쇄된 슬러지를 다시 한번 미세하기 분쇄하기 위한 것으로, 그 구성은 다음과 같다.The impeller 50 is a very important configuration in the present invention for the solid sludge introduced through the inlet 21 to crush the finely crushed sludge once again by the crushing blade 60, the configuration Is as follows.
도 4에 확대 도시한 바와 같이 본 발명 임펠러(50)는 축(12)에 결합되는 원통형의 허브(51a)와, 상기 허브(51a)의 외주면에 일체로 형성된 고정대(51b)와, 상기 고정대(51b)에 볼트(51c)에 의해 결합된 분쇄용 칼날(51d)로 이루어지는 전방임펠러(51)와, 상기 전방임펠러(51)의 일단에 일체로 형성된 원판(52a)과 날개(52b)로 이루어지는 후방임펠러(52)로 구성된 것이다.As shown in FIG. 4, the impeller 50 of the present invention includes a cylindrical hub 51a coupled to the shaft 12, a fixing stand 51b integrally formed on an outer circumferential surface of the hub 51a, and the fixing stand ( The front impeller 51 which consists of the grinding | pulverization blade 51d couple | bonded with 51b by the bolt 51c, and the back which consists of the disk 52a and the blade 52b integrally formed in the one end of the said front impeller 51 It is composed of an impeller (52).
상기 후방임펠러(52)는 전방임펠러(51)의 회전에 의해 흡입구(21)를 통해 흡입되는 액체가 강한 압력에 의해 흡입구(21)의 반대편 본체(10)와 축(12)의 틈 사이로 새는 것을 방지하기 위한 것이다. 또한 상기 후방임펠러(52)는 액체와 슬러지의 토출압력을 높여주는 기능을 하기도 한다.The rear impeller 52 leaks the liquid sucked through the inlet 21 by the rotation of the front impeller 51 between the main body 10 on the opposite side of the inlet 21 and the gap between the shaft 12 by the strong pressure. It is to prevent. In addition, the rear impeller 52 also serves to increase the discharge pressure of the liquid and sludge.
상기 전방임펠러(51)의 흡입압력은 허브(51a) 외주면에 일체로 형성된 고정대(51b)가 축방향과 수평으로 θ각(약 12~17°) 정도 비틀려 있기 때문에 가능한 것이다. 즉 도 4를 참조하여 볼 때 축(12)이 시계방향으로 회전하게 되면 액체와 슬러지는 축방향의 흡입력을 받으면서 동시에 원심력에 의해 토출구(11)를 통해 배출되어지는 것이다.The suction pressure of the front impeller 51 is possible because the holder 51b formed integrally with the outer circumferential surface of the hub 51a is twisted about θ angle (about 12 to 17 °) in the axial direction and horizontally. That is, when the shaft 12 rotates in the clockwise direction with reference to FIG. 4, the liquid and the sludge receive the suction force in the axial direction and are discharged through the discharge port 11 by the centrifugal force.
물론 축(12)이 반대방향으로 회전하면 오히려 액체와 슬러지는 축방향으로 배출되어질 것이다.Of course, if the shaft 12 rotates in the opposite direction, the liquid and sludge will be discharged in the axial direction.
흡입구(21)의 입구부, 즉 축(12)의 가장 선단부에는 +자형상을 갖는 2개의 파쇄용 칼날(60)이 형성되어지며, 각 파쇄용 칼날(60)의 형태는 수직방향의 칼날들은 길고 수평방향의 칼날들은 짧게 형성되어진다. 이때 2개의 파쇄용 칼날(60)이 서로 엇갈리게 축착되어짐이 바람직하다.At the inlet portion of the suction port 21, that is, the tip of the shaft 12, two shredding blades 60 having a + shape are formed, and each shredding blade 60 has a vertical blade shape. Long horizontal blades are formed short. At this time, it is preferable that the two shredding blades 60 are alternately condensed with each other.
이처럼 본 발명의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the present invention as follows.
흡입구(21)를 통해 흡입된 액체와 슬러지 중에서 덩어리가 큰 슬러지만 먼저 파쇄형 칼날(60)에 의해 조대한 입자로 파쇄한 다음, 일단 파쇄된 슬러지를 분쇄망(40)으로 유입시켜 분쇄망(40)의 원통체(42) 내면과 거의 맞닿는 상태로 회전하고 있는 분쇄용 칼날(51d)에 의해 분쇄망(40)을 통과하기 전에 다시 한번 미세하게 분쇄하여 액체와 함께 토출되도록 한 것이다.Among the liquid and sludge sucked through the suction port 21, the sludge has a large mass, but is first crushed into coarse particles by the crushed blade 60, and then the crushed sludge is introduced into the crushing network 40 to obtain a crushing network ( Before passing through the grinding net 40 by the grinding blade 51d which is rotated in contact with the inner surface of the cylindrical body 42 of 40), fine grinding | pulverization is once again discharged with a liquid.
이처럼 본 발명 양수기는 흡입구를 통해 흡입되는 액체와 슬러지중에서 덩어리가 큰 슬러지만 먼저 분쇄하여 부피를 줄이고, 다시 임펠러에 형성된 분쇄용 칼날에 의해 다시 한번 분쇄하는 슬러지의 크기에 따른 순차적인 분쇄가 가능하며, 펌핑과 동시에 슬러지를 곧바로 미세한 입자로 만들어 액체와 함께 토출되도록 함으로써 액체와 슬러지의 토출력이 좋아지고, 따라서 작은 용량의 양수기를 사용하더라도 동일한 효율을 가질 수 있는 것이다.As described above, the water pump of the present invention is capable of sequential crushing according to the size of the sludge, which is pulverized in the liquid and sludge sucked through the inlet, but pulverized first to reduce the volume, and crushed again by the grinding blade formed in the impeller At the same time, the sludge is made into fine particles at the same time as pumping and discharged together with the liquid, so that the output power of the liquid and the sludge is improved, and thus the same efficiency can be obtained even when a small capacity pump is used.
또한 본 발명 임펠러는 임펠러의 기능을 하면서 동시에 분쇄기능을 하는 것이므로 분쇄효율 및 토출효율이 좋아지는 것이며, 파쇄용 칼날 및 분쇄용 칼날을 교환 가능하므로 유지보수비용을 현저히 줄일 수 있는 매우 유용한 발명인 것이다.In addition, the present invention impeller is a function of the impeller and at the same time crushing function is to improve the crushing efficiency and discharge efficiency, it is a very useful invention that can significantly reduce the maintenance cost because the shredding blade and the crushing blade can be replaced.
