본 발명은 스크류 펌프에 관한 것으로서, 스크류의 회전과 함께 하우징 및 부쉬가 회전되도록 하고, 샤프트는 고정되도록 하여 부쉬의 마모를 거의 발생시키지 않아 부쉬의 수명을 연장시키는 스크류 펌프에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw pump, wherein the housing and the bush are rotated with the rotation of the screw, and the shaft is fixed to the screw pump to extend the life of the bush with little occurrence of the wear of the bush.

일반적으로 스크류 펌프는 파이프가 연결된 일측이 수중이나 고분자 물질, 하수처리장이나 정화조의 오수 등 점성이 큰 혼합물(이하에서는 '펌핑 대상물' 이라 한다) 속에 담겨져 있고, 구동 펌프 및 모터가 연결된 타측이 지상에 형성되어 구동 펌프 및 모터에 의한 동력으로 스크류를 회전시켜 펌핑 대상물에 에너지를 전달하여 상측으로 퍼올리는 것이다.In general, a screw pump is contained in a highly viscous mixture (hereinafter referred to as a 'pumping object'), such as water, polymer material, sewage treatment plant or septic tank sewage, and one side to which the pipe is connected is connected to the ground. Is formed to rotate the screw by the power of the drive pump and the motor to transfer the energy to the pumping object to be pumped up.

이러한 스크류 펌프에서, 도 1에 도시된 바와 같이, 펌핑 대상물 속에 담겨져 있는 스크류(10) 전단부를 살펴보면 스크류의 축(20)과 일체로 형성되어 스크류(10)와 함께 회전되는 샤프트(50)와, 펌핑 대상물 속에 담겨져 있게 되는 스크류(10)의 회전에 따른 진동으로 스크류 펌프의 일측이 움직이지 않도록 고정시키면서 동시에 샤프트(50)를 수용하는 하우징(30), 그리고 상기 샤프트(50)와 하우징(30) 사이에 삽입되어 샤프트 및 하우징의 마모를 방지하기 위한 부쉬(40)로 크게 구성되어져 있다. 여기에서 상기 하우징(30)은 기저부(f) 즉, 하수처리장 또는 정화조의 바닥면과 고정되거나 바닥면에 설치된 고정 구조물에 고정되게 된다.In such a screw pump, as shown in FIG. 1, when looking at the front end of the screw 10 contained in the pumping object, the shaft 50 is integrally formed with the shaft 20 of the screw and rotates together with the screw 10. Housing 30 for accommodating the shaft 50 while fixing one side of the screw pump so as not to move due to the vibration of the screw 10 to be contained in the pumping object, and the shaft 50 and the housing 30 It is largely composed of a bush 40 inserted in between to prevent abrasion of the shaft and the housing. Here, the housing 30 is fixed to the bottom portion f, that is, the bottom surface of the sewage treatment plant or the septic tank or fixed structure installed on the bottom surface.

일반적으로 스크류 펌프의 스크류 전단부 즉, 펌핑 대상물 속에 담겨져 있는 부분은 항상 펌핑 대상물 속의 수중에 존재하게 되므로 그 고장 상태나 샤프트, 하우징 및 부쉬의 마모 상태를 확인하는 것이 어려울 뿐만 아니라, 마모의 확인 후에도 그 교체 작업이 용이하지 않은 문제점이 있다.In general, the screw front end of the screw pump, that is, the part contained in the pumping object is always present in the water in the pumping object, so it is not only difficult to check the failure state or the wear state of the shaft, the housing, and the bush, but also after the wear is confirmed. There is a problem that the replacement operation is not easy.

특히 종래의 스크류 펌프는 하우징 및 부쉬가 고정된 상태에서 스크류와 연결된 샤프트만 회전하는 구조로써, 일반적으로 스크류 펌프가 바닥면에 대해 사선으로 기울여져 사용되는 것을 감안한다면, 상기 스크류에 결합된 샤프트에 의한 하 중이 부쉬의 아래측으로 주로 작용하게 되어, 이 부분에 해당하는 부쉬의 내면이 쉽게 마모되는 단점이 있었다.In particular, the conventional screw pump is a structure that rotates only the shaft connected to the screw while the housing and the bush is fixed, in general, considering that the screw pump is used inclined diagonally with respect to the bottom surface, the shaft coupled to the screw Due to the load acts mainly to the lower side of the bush, there was a disadvantage that the inner surface of the bush corresponding to this part is easily worn.

이에 의해 부쉬의 수명이 단축되어 스크류 펌프가 제대로 작동하지 않는 염려가 있으며, 교체 주기가 그 만큼 짧아져 경제적으로 낭비가 되고 있으며, 교체 작업 또한 용이하지 않아 인건비나 시간상으로도 낭비를 초래하고 있다.As a result, the life of the bush is shortened, and there is a concern that the screw pump does not operate properly. The replacement cycle is shortened so that it is economically wasteful, and the replacement work is not easy, causing labor and time waste.

본 발명은 상기 문제점을 해결하기 위해 안출된 것으로서, 스크류의 회전과 함께 하우징 및 부쉬가 회전되도록 하고, 샤프트는 고정되도록 하여 부쉬의 마모를 거의 발생시키지 않아 부쉬의 수명을 연장시키는 스크류 펌프의 제공을 그 목적으로 한다.The present invention has been made to solve the above problems, the housing and the bush to be rotated with the rotation of the screw, the shaft is fixed to provide a screw pump that extends the life of the bush hardly causing the wear of the bush For that purpose.

상술한 바와 같은 목적 달성을 위해 본 발명은, 일측이 펌핑 대상물이 포함되어 있는 장소의 기저부에 고정되고, 타측은 지상부에 고정된 스크류 펌프에 있어서, 스크류의 축 전단에 고정결합되는 하우징과; 상기 하우징 내에 끼워져 상기 하우징과 고정결합되는 부쉬와; 후측은 상기 부쉬 내에 끼워지고, 전측은 기저부에 고정결합되는 샤프트;를 포함하여 구성되어, 스크류의 회전에 따라 상기 하우징 및 부쉬가 회전되도록 형성된 것을 특징으로 하는 스크류 펌프를 기술적 요지로 한다.In order to achieve the object as described above, the present invention is a screw pump fixed to the base portion of the place where the pumping object is included, the other side is fixed to the ground portion, the housing fixed to the shaft front end of the screw; A bush inserted into the housing and fixedly coupled to the housing; The rear side is fitted in the bushing, the front side is configured to include a; shaft is fixed to the base, and the screw pump, characterized in that the housing and the bush is formed to rotate as the screw rotates.

이에 따라 스크류의 회전과 함께 하우징 및 부쉬가 회전되도록 하고, 샤프트는 고정되도록 하여 샤프트와 부쉬 간의 마찰면이 회전되도록 하여 부쉬의 마모를 거의 발생시키지 않아 부쉬의 수명을 연장시킬 수 있으며, 이에 따라 부쉬의 교체 기간이 길어져 경제적임과 동시에 스크류 펌프의 오작동을 방지하여 효율적인 펌핑 작업이 가능한 이점이 있다.Accordingly, the housing and the bush are rotated with the rotation of the screw, and the shaft is fixed so that the friction surface between the shaft and the bush is rotated so that the wear of the bush is hardly generated, thereby extending the life of the bush. The replacement period is long, economical, and at the same time prevents the malfunction of the screw pump has the advantage that can be pumped efficiently.

이하에서는 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하고자 한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 2는 본 발명에 따른 스크류 펌프의 주요부에 대한 개략도이고, 도 3은 종래 및 본 발명에 따른 스크류 펌프의 샤프트, 부쉬 및 하우징의 작용예시도이다.Figure 2 is a schematic diagram of the main part of the screw pump according to the present invention, Figure 3 is a working example of the shaft, bush and housing of the screw pump according to the prior art and the present invention.

일반적으로 스크류 펌프의 일측은 펌핑 대상물이 포함되어 있는 장소의 기저부(f)에 고정되고, 타측은 지상부에 고정되어 있게 된다. 즉, 하수처리장이나 정화조 등의 바닥면이나 바닥측에 형성된 고정된 구조물 등이 기저부(f)가 되고, 하수처리장이나 정화조 등의 입구측의 고정된 구조물이 지상부가 되게 된다.In general, one side of the screw pump is fixed to the base portion (f) of the place where the pumping object is contained, the other side is fixed to the ground portion. That is, the bottom part f of the bottom surface of a sewage treatment plant or a septic tank, etc. becomes a base part f, and the fixed structure of the inlet side of a sewage treatment plant or a septic tank becomes a ground part.

본 발명에서는 스크류 펌프의 일측 즉, 펌핑 대상물이 포함되어 있는 장소의 기저부(f)에 고정되는 스크류 펌프의 전측의 구조에 대한 것으로서, 도시된 바와 같이 본 발명에 따른 스크류 펌프는 하우징(100), 부쉬(200) 및 샤프트(300)로 크게 구성된다.In the present invention, for the structure of the front side of the screw pump fixed to one side of the screw pump, that is, the base portion (f) of the place where the pumping object is included, as shown, the screw pump according to the present invention is a housing 100, It consists largely of the bush 200 and the shaft 300.

먼저, 상기 하우징(100)은 스크류의 축(20) 전단에 결합고정되는 것으로서, 상기 스크류의 축(20)이 원통 형상으로 형성되므로 상기 스크류의 축(20)에 결합되는 부분인 상기 하우징(100) 후측의 형상도 이에 대응되어 원형의 디스크 형상으로 형성되며, 중심에는 후술할 샤프트(300) 및 부쉬(200)가 끼워질 수 있도록 부쉬(200)의 지름에 대응되는 정도의 크기의 통공이 형성되어 있다.First, the housing 100 is fixed to the front end of the shaft 20 of the screw, the shaft 20 of the screw is formed in a cylindrical shape, the housing 100 which is a part coupled to the shaft 20 of the screw The rear side also corresponds to the circular disk shape, and the center has a through hole having a size corresponding to the diameter of the bush 200 so that the shaft 300 and the bush 200 to be described later can be fitted. It is.

또한 상기 하우징(100) 전측 즉 부쉬(200) 및 샤프트(300)가 결합되는 부분은 부쉬(200)가 충분히 끼워질 수 있을 정도 길이를 가지는 상기 통공에 연통되는 수용공이 형성되고, 외주면의 형상은 펌핑 대상물과의 마찰력을 최소화하기 위해 앞쪽으로 갈수록 가늘게 형성되며, 상기 하우징(100)이 스크류의 축(20)과의 착탈결합할 수 있도록 둘레를 따라 나사공이 형성되며, 나사공에 볼트가 결합되어 스크류의 축(20)과 고정결합되게 된다.In addition, the front side of the housing 100, that is, the portion in which the bush 200 and the shaft 300 are coupled is formed with a receiving hole communicating with the through hole having a length enough to allow the bush 200 to be sufficiently fitted, and the shape of the outer circumferential surface is In order to minimize the frictional force with the pumping object is formed thinner toward the front, a screw hole is formed along the circumference so that the housing 100 can be attached and detached with the shaft 20 of the screw, the bolt is coupled to the screw hole It is fixed to the shaft 20 of the screw.

그리고 상기 부쉬(200)는 원통형 관의 형상을 띄고, 상기 하우징(100)의 수용공에 끼워지게 되며, 상기 부쉬(200) 내부로는 후술할 샤프트(300)가 끼워지게 된다. 상기 부쉬(200)는 상기 하우징(100)의 수용공에 끼워짐과 동시에 상기 하우징(100)에 고정결합되게 된다.In addition, the bush 200 has a cylindrical tube shape and is fitted into the receiving hole of the housing 100, and the shaft 300 to be described later is inserted into the bush 200. The bush 200 is fitted into the receiving hole of the housing 100 and fixedly coupled to the housing 100.

이에 의해 상기 스크류(10)의 회전에 의해 이에 고정결합된 하우징(100)이 회전되게 되고, 연속적으로 이에 고정결합된 부쉬(200)가 회전되게 된다.As a result, the housing 100 fixed thereto is rotated by the rotation of the screw 10, and the bush 200 fixedly coupled thereto is rotated continuously.

그리고, 상기 샤프트(300)는 원통형으로 길게 형성되어, 후측은 상기 부쉬(200) 내에 끼워지고, 전측은 기저부(f)에 고정결합되게 된다. 종래의 샤프트는 스크류의 축 전단에서 연속적으로 연장되어 돌출되게 형성된 것이나, 본 발명에서의 샤프트는 스크류의 축과는 분리된 구조를 가지는 것으로 스크류의 회전에 의해 회전되지 않도록 형성된 것이다.In addition, the shaft 300 is formed to have a long cylindrical shape, the rear side is fitted into the bush 200, the front side is fixedly coupled to the base (f). Conventional shafts are formed to extend continuously and protrude from the front end of the screw shaft, but the shaft in the present invention has a structure separate from the shaft of the screw is formed so as not to rotate by the rotation of the screw.

상기 샤프트(300)는 기저부(f)에 전측이 고정결합되어 움직이지 않도록 형성되며, 후측은 상기 부쉬(200) 내로 수용되어 하우징(100)과 결합된 스크류(10)의 위치를 잡아주고 움직이지 않도록 고정시키게 된다.The shaft 300 is formed so that the front side is fixedly coupled to the base portion f so as not to move, and the rear side is accommodated in the bush 200 to hold the position of the screw 10 coupled with the housing 100 and move. To be fixed.

이에 의해 상기 스크류(10)의 회전에 의해 스크류의 축(20)에 고정 결합되어 있는 상기 하우징(100) 및 부쉬(200)만 회전하게 되고, 상기 샤프트(300)는 기저부(f)에 고정되어 스크류(10)를 지지해주는 역할만 하게 된다.As a result, only the housing 100 and the bush 200 which are fixedly coupled to the shaft 20 of the screw by the rotation of the screw 10 are rotated, and the shaft 300 is fixed to the base f. Only serves to support the screw (10).

따라서, 도 3에 도시된 바와 같이, 종래의 스크류와 샤프트(50)가 일체로 형성되어 샤프트(50)가 부쉬(40) 및 하우징(30)내에서 회전하는 구조는 부쉬(40) 내부의 일측을 계속적으로 마모시키는 반면에, 본 발명에 따른 구조는 샤프트(300)는 회전하지 않고 그 외부의 부쉬(200)가 회전하게 되어 스크류(10)의 회전에 따른 부쉬(200)의 마모가 거의 발생하지 않게 되며, 설사 부쉬(200)가 마모되더라도 부쉬(200) 및 하우징(100)이 회전하므로서 부쉬(200)의 내면에 균일하게 마모가 발생하여 그 만큼 부쉬(200)의 교체 주기가 길어지게 되는 것이다.Therefore, as shown in FIG. 3, the conventional screw and the shaft 50 are integrally formed so that the shaft 50 rotates in the bush 40 and the housing 30 at one side inside the bush 40. On the other hand, the structure according to the present invention, the shaft 300 does not rotate, but the outer bush 200 is rotated so that the wear of the bush 200 due to the rotation of the screw 10 almost occurs Even if the diarrhea bush 200 is worn, the bush 200 and the housing 100 rotate so that wear occurs uniformly on the inner surface of the bush 200, so that the replacement cycle of the bush 200 becomes longer. will be.

상기 구성에 의한 본 발명은, 스크류의 회전과 함께 하우징 및 부쉬가 회전되도록 하고, 샤프트는 고정되도록 하여 샤프트와 부쉬 간의 마찰면이 회전되도록 하여 부쉬의 마모를 거의 발생시키지 않아 부쉬의 수명을 연장시킬 수 있으며, 이에 따라 부쉬의 교체 기간이 길어져 경제적임과 동시에 스크류 펌프의 오작동을 방지하여 효율적인 펌핑 작업이 가능한 효과가 있다.According to the present invention, the housing and the bush are rotated together with the rotation of the screw, and the shaft is fixed so that the friction surface between the shaft and the bush is rotated so that the wear of the bush is hardly generated, thereby extending the life of the bush. As a result, the replacement period of the bush is longer, which is economical and prevents a malfunction of the screw pump, thereby enabling an efficient pumping operation.
