Description

고형물 및 고점도 물질 이송용 펌프{Pumping device for fluid}Pump for transporting solids and high viscosity materials

본 발명은 고형물 및 고점도 물질 이송용 펌프에 관한 것으로, 더욱 상세하게는 고형물을 이송하거나 또는 점도가 높고 비중이 높은 유체를 이송하는 펌프의 내부 구조를 변경한 후, 상기 변경된 부분들에 의해 유체가 흡입구로 유입될 시 진공 흡입됨과 동시에 유체가 강한 회전력을 바탕으로 용이하게 토출구측으로 이송될 수 있도록 한 고형물 및 고점도 물질 이송용 펌프에 관한 것이다.The present invention relates to a pump for transporting solids and high viscosity materials, and more particularly, after changing the internal structure of the pump for transporting solids or transporting fluids having high viscosity and high specific gravity, The present invention relates to a pump for transporting solids and high-viscosity materials, which allows vacuum to be sucked in at the same time as it enters the suction port, and the fluid can be easily transported to the discharge port based on a strong rotational force.

일반적으로 펌프는 사용목적에 따라 토출량과 전양정이 결정되면 이에 가장 적합한 펌프의 형식을 정하고 있으며 주어진 토출량과 전양정의 조합에 대해서 회전수와 단수를 정하는 데 따라 여러 가지 형식의 펌프가 채용가능하다.In general, when the discharge amount and the total head are determined according to the purpose of use, the pump determines the type of pump that is most suitable for this purpose, and various types of pumps can be adopted to determine the number of revolutions and the number of stages for the combination of the discharge amount and the total head. .

따라서 개개의 용도와 사양점에 있어서 펌프의 효율이 최대로 되게 하기 위해서는 개개의 펌프를 개별로 설계, 제작해야 하기 때문에 비경제적이라 할 수 있고, 보통은 모든 형태의 펌프중 가장 구조가 간단하고 제작이 용이한 원심펌프가 펌프 사용량의 대부분을 차지하고 있다. Therefore, in order to maximize the efficiency of the pump in each use and specification point, it is inconvenient because each pump must be designed and manufactured individually, and it is usually the simplest and the most structure of all types of pumps. This easy centrifugal pump accounts for most of the pump usage.

본 발명은 원심력을 이용한 펌프에 관한 것으로, 이의 구조를 간단하게 살펴보면 흡입구와 토출구가 형성된 펌프 케이싱 상단에 구동모터가 형성되고, 이 구동모터의 회전축에 연결된 회전수단을 이용하여 유체를 흡입구에서 토출구로 이송시키는 구성을 가지고 있으며, 회전수단으로 임펠러가 사용된다.The present invention relates to a pump using a centrifugal force, and when the structure thereof is briefly described, a driving motor is formed on an upper end of a pump casing in which an inlet and an outlet are formed, and fluid is transferred from the inlet to the outlet using a rotating means connected to the rotation shaft of the drive motor. It has a structure to transfer and an impeller is used as a rotating means.

상기와 같은 종래 펌프는 펌프 케이싱 내에 설치된 임펠러의 원심력을 이용하여 임펠러 내에서 유체를 밀어내는 방식으로 유체를 이송하고 있으나, 이와 같이 임펠러를 이용한 밀어내기 방식은 임펠러의 회전력이 강하지 못하기 때문에 고형물을 이송할 때 또는 점도가 높고 비중은 높은 유체를 이송하기에는 많은 어려움이 이 있을 뿐 아니라, 유체속에 포함된 자갈 등과 같은 단단한 고형 물질이 있을 때에는 임펠러가 파손되면서 펌프의 고장율을 증가시키는 요인이 되었다.Conventional pumps as described above transfer the fluid by pushing the fluid in the impeller by using the centrifugal force of the impeller installed in the pump casing, but the push method using the impeller as described above is a solid material because the rotational force of the impeller is not strong When conveying or conveying a fluid having a high viscosity and a high specific gravity, there are many difficulties, and when there is a hard solid material such as gravel included in the fluid, the impeller breaks, causing a failure rate of the pump.

또한, 종래 펌프에는 회전력을 강하게 증가시키거나 유체가 흡입될 시 진공 흡입되는 별도의 장치가 마련되어 있지 않기 때문에 단단한 고형물이나 점도가 높고 비중은 높은 유체는 용이하게 이송하지 못하는 등의 제반 문제점이 발생되었다. In addition, since the conventional pump is not provided with a separate device that strongly increases the rotational force or vacuum suction when the fluid is sucked in, there are various problems such as hard solids or high viscosity and high specific gravity does not easily transfer the fluid. .

본 발명은 상기와 같은 문제점을 감안하여 안출한 것으로, 고형물을 이송하거나 또는 점도가 높고 비중이 높은 유체를 이송하는 펌프의 내부 구조를 변경한 후, 상기 변경된 부분들에 의해 유체가 흡입구로 유입될 시 진공 흡입됨과 동시에 유체가 강한 회전력을 바탕으로 용이하게 토출구측으로 이송될 수 있도록 한 고형물 및 고점도 물질 이송용 펌프를 제공하는 데 있다.The present invention has been made in view of the above problems, and after changing the internal structure of the pump for transporting solids or for transporting fluids with high viscosity and high specific gravity, fluid may be introduced into the inlet by the changed parts. The present invention provides a pump for transporting solids and high viscosity materials, which allows vacuum to be sucked at the same time and allows fluids to be easily transported to a discharge port based on a strong rotational force.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로 흡입구와 토출구가 형성된 펌프 케이싱 상단에 구동모터가 형성되고, 이 구동모터의 회전축에 연결된 회전수단을 이용하여 유체를 흡입구에서 토출구로 이송시키는 고형물 및 고점도 물질 이송용 펌프에 있어서, 상기 회전수단은 로터로 형성되고 이 로터의 강한 회전력에 의해 유체가 토출구측으로 밀려 나가게 하는 것과; 상기 펌프 케이싱 하부에 형성되면서 상단과 하단은 넓고 중간은 좁은 형태로 이루어지며 유체가 흡입될 때 진공 흡입되게 하는 진공흡입부와; 상기 진공흡입부 내벽에 형성되고 흡입되는 유체의 회전력을 증가시키는 나선형돌기로 구성되는 것을 그 기술적 구성상의 기본 특징으로 한다. The present invention is a drive motor is formed on the upper end of the pump casing inlet and discharge port formed as a means for achieving the above object, the solid material for transferring the fluid from the suction port to the discharge port using the rotating means connected to the rotation axis of the drive motor and A pump for conveying a high viscosity material, wherein the rotating means is formed of a rotor to cause the fluid to be pushed toward the discharge port by the strong rotational force of the rotor; A vacuum suction unit formed at a lower portion of the pump casing, the upper and lower ends of the pump casing being wide and the middle of the pump casing having a narrow shape; It is a basic feature of the technical configuration that consists of a spiral protrusion formed on the inner wall of the vacuum suction portion and increases the rotational force of the fluid sucked.

이상에서 살펴본 바와 같이 본 발명에 따르면 고형물을 이송하거나 또는 점도가 높고 비중이 높은 유체를 이송하는 펌프의 내부 구조가 변경되어 있다. 즉, 회전수단으로 회전력이 강한 로터가 사용되고, 펌프 케이싱 하부에는 진공흡입부와 진공흡입부 내벽에 나선형돌기가 형성되어 있다.As described above, according to the present invention, the internal structure of the pump for transporting solids or for transporting fluids having high viscosity and high specific gravity is changed. That is, a rotor having strong rotational force is used as the rotating means, and a spiral protrusion is formed on the inner wall of the vacuum suction unit and the vacuum suction unit at the bottom of the pump casing.

따라서 상기 변경된 로터, 진공흡입부, 나선형돌기에 의해 유체가 흡입구로 유입될 시 진공 흡입됨과 동시에 유체가 강한 회전력을 바탕으로 용이하게 토출구측으로 이송되는 것이다.Therefore, when the fluid is introduced into the suction port by the changed rotor, the vacuum suction part, and the spiral projection, the fluid is easily sucked to the discharge port side based on the strong rotational force.

이하 본 발명의 바람직한 실시예를 첨부 도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 펌프도 흡입구(110)와 토출구(120)가 형성된 펌프 케이싱(100) 상단에 구동모터(200)가 형성되고, 이 구동모터(200)의 회전축(300)에 연결된 회전수단을 이용하여 유체를 흡입구(110)에서 토출구(120)로 이송시키며, 고형물 및 고점도 물질 이송용으로 사용되는 것은 종래와 같다. In the pump of the present invention, the driving motor 200 is formed on the upper end of the pump casing 100 in which the suction port 110 and the discharge port 120 are formed, and by using a rotating means connected to the rotating shaft 300 of the driving motor 200. The fluid is transferred from the suction port 110 to the discharge port 120, and is used for transporting solids and high viscosity materials as in the related art.

다만, 본 발명은 더욱 효과적으로 유체를 이송시킬 수 있도록 한 것으로 이는 도1과 도2에서와 같이 회전수단은 로터(400)로 형성되고 이 로터(400)의 강한 회전력에 의해 유체가 토출구(120)측으로 밀려 나가게 하였다. 즉, 로터(400)는 강한 회전력을 갖기 때문에 유체가 로터(400) 내부에 들어오는 것이 아니라, 로터의 강한 회전력에 의하여 토출구(120)측으로 유체가 밀려 나가는 현상이 발생게 된다.However, the present invention allows the fluid to be transported more effectively. As shown in FIGS. 1 and 2, the rotating means is formed of the rotor 400 and the fluid is discharged by the strong rotational force of the rotor 400. Pushed to the side. That is, since the rotor 400 has a strong rotational force, the fluid does not enter the rotor 400, but the fluid is pushed toward the discharge port 120 by the strong rotational force of the rotor.

펌프 케이싱(100) 하부에는 진공흡입부(500)가 형성되는데, 이 진공흡입부(500)는 상단(C)과 하단(A)은 넓고 중간(B)은 좁은 형태로 이루어진다. 따라서 유체가 흡입구(110)로 유입될 시 최초 하단(A)을 통과한 유체는 중간(B)을 거칠때 순간적으로 진공 흡입됨과 동시에 나선형돌기(600)를 따라 흡입되기 때문에 흡입구(110)로 흡입된 유체는 강력한 회전력을 발생하되면서 토출구(120)로 용이하게 이송하게 되는 것이다. A vacuum suction part 500 is formed below the pump casing 100, and the vacuum suction part 500 has a wide upper end C and a lower end A and a middle B narrow. Therefore, when the fluid flows into the inlet 110, the fluid that has passed through the first lower end A is sucked into the inlet 110 because it is sucked along the spiral protrusion 600 at the same time as it is instantaneously vacuumed when passing through the middle B. The fluid is to be easily transported to the discharge port 120 while generating a strong rotational force.
