본 발명은, 약품분사기의 임펠러에 관한 것으로서, 보다 상세하게는 약품분사 영역을 확대할 수 있도록 구조가 개선된 약품분사기의 임펠러에 관한 것이다. The present invention relates to an impeller of a chemical injector, and more particularly, to an impeller of a chemical injector having an improved structure to expand a chemical injection region.

일반적으로 오수 및/또는 폐수처리 공정에서는 오염수에 약품을 투입하여 오염수의 정화를 촉진시키기 위해서 약품분사기를 사용하고 있으며, 이러한 약품분사기는 해당 약품을 오염수에 보다 빠르게 혼합시키는 것과, 분사영역을 넓게 형성하 느냐에 따라서 그 성능이 좌우된다. In general, the sewage and / or wastewater treatment process uses a chemical sprayer to inject the chemical into the contaminated water to promote the purification of the contaminated water, and the chemical sprayer mixes the chemical with the contaminated water more quickly, Its performance depends on whether it is widely formed.

종래 약품분사기(201)는 도 1에 도시된 바와 같이, 모터(230)로부터 전달되는 회전동력에 의해서 임펠러(210)가 처리수중에서 고속 회전하게 되면, 임펠러(210) 후면(도면상 임펠러(210) 상부)에 위치한 유체가 전방(도면상 임펠러(210) 하부)으로 빨려가면서 일정 유속을 형성하게 되는데, 이때, 임펠러(210)의 후면에 위치한 진공강화기(220)를 이용하여 임펠러(210) 전방으로 향하는 유체의 흐름을 일정부분 차단하게 되면 임펠러(210)와 진공강화기(220) 사이에 동공 현상에 의한 진공력이 발생하게 되고, 이때, 발생된 진공력이 진공포트(240)와 약품유입관(250)을 통해 외부의 약품을 흡입하여 처리수중으로 분사하는 방식으로 운영되어 왔다. As shown in FIG. 1, the conventional medicine sprayer 201 rotates at a high speed in the treated water by the rotational power transmitted from the motor 230, and the back of the impeller 210 (impeller 210 on the drawing). The fluid located in the upper part) is sucked to the front (lower impeller 210 on the drawing) to form a certain flow rate, in which case, the impeller 210 using the vacuum intensifier 220 located at the rear of the impeller 210. When the flow of the fluid to the front is cut off at a certain part, a vacuum force is generated between the impeller 210 and the vacuum intensifier 220, and the generated vacuum force is the vacuum port 240 and the chemicals. It has been operated by injecting the external chemicals through the inlet pipe 250 and sprayed into the treated water.

그러나, 이러한, 종래 약품분사기는 임펠러의 분사력이 작용하는 처리수의 흐름이 일정하지 않거나 난류가 발생될 경우, 임펠러에 순간적인 저항이 발생하여 임펠러 후면에 진공생성이 원활하게 이루어지지 않아 처리수가 진공포트로 역류함으로써, 약품분사가 원활하게 이루어지지 못하는 문제점이 있었다. However, such a conventional chemical spraying machine does not smoothly generate a vacuum on the back of the impeller due to instantaneous resistance occurs when the flow of the treated water to which the impeller jetting force acts is not constant or turbulent flow occurs, so that the treated water is not vacuumed. By backflowing to the pot, there was a problem that the drug injection can not be made smoothly.

또한, 종래 약품분사기는 임펠러의 구조상 유체의 흐름이 임펠러의 후방으로부터 임펠러의 전방(도면상 처리수중 하부방향)으로 형성되기 때문에, 약품분사영역은 처리수중의 하부 영역으로만 제한 적으로 분사되는 단점이 있었다. 이러한 분사영역의 제한은 약품이 처리수중에 혼합되는 시간을 증가시켜 오염수 정화성능을 저하시키는 문제를 발생시킨다. In addition, the conventional chemical spraying machine has a disadvantage in that the chemical injection region is limited to the lower region of the treated water because the flow of fluid is formed from the rear of the impeller to the front of the impeller (downward in the treated water on the drawing). There was this. This limitation of the spraying area causes a problem of increasing the time that the chemical is mixed in the treated water, thereby lowering the polluted water purification performance.

이러한, 종래 약품분사기(201)의 문제점을 해결하기 위해서, 도 2에 도시된 바와 같은 약품분사기(101)가 한국 등록실용신안공보 등록번호 제20-0339277호에 개시된 바 있다. In order to solve such a problem of the conventional drug injector 201, the drug injector 101 as shown in Figure 2 has been disclosed in Korean Utility Model Registration No. 20-0339277.

이 약품분사기(101)는 외부로부터 공급된 약품이 유입관(150)을 통하여 유입포트(160)로 들어오면, 터빈축(120)에 부착된 터빈(127)이 모터(130)의 회전력에 의해 압력챔버(140) 입구에서 터빈축(120)과 함께 고속회전하면서, 유입포트(160) 내부의 약품을 압력챔버(140) 쪽으로 밀어냄과 동시에, 터빈펌프의 흡입원리와 같이, 외부의 약품을 수중으로 끌어들이는 기능을 수행하도록 하였으며, 터빈(127)에 의해 압력챔버(140)로 밀려나온 약품은 압력챔버(140) 내부에서의 압력 상승으로 인하여, 다시 터빈축(120)의 약품배출구(125)를 통하여 터빈축(120) 속의 약품유도로(123)를 따라 약품토출구(121)를 통하여 임펠러분사구(111)로 배출되면, 임펠러(110)의 회전 원심력에 의해 약품이 임펠러(110)의 둘레방향과 처리수중의 하부방향으로 분사되도록 하였다. When the chemical injector 101 is supplied from the outside into the inlet port 160 through the inlet pipe 150, the turbine 127 attached to the turbine shaft 120 is driven by the rotational force of the motor 130 While rotating at a high speed with the turbine shaft 120 at the inlet of the pressure chamber 140, the chemicals inside the inlet port 160 are pushed toward the pressure chamber 140, and external chemicals, such as the suction principle of the turbine pump, are removed. The chemicals pushed out into the pressure chamber 140 by the turbine 127 are again discharged by the turbine shaft 120 due to the pressure increase in the pressure chamber 140. When discharged to the impeller injection port 111 through the chemical discharge port 121 along the chemical induction path 123 in the turbine shaft 120 through the 125, the chemicals of the impeller 110 by the rotating centrifugal force of the impeller 110 It was made to spray in the circumferential direction and the lower direction in the treated water.

그런데, 이러한 종래 또 다른 약품분사기는, 약품이 임펠러의 각 날개 사이에 형성된 임펠러분사구로 분사됨으로써, 처리수의 역류를 걱정하지 않고, 약품의 분사영역을 임펠러의 하부방향을 포함한 둘레영역으로 확대하긴 하였지만, 임펠러의 구조상(임펠러의 비틀림각의 구조상) 약품 분사영역은 임펠러의 하부 방향으로 치우칠 수밖에 없다. 따라서, 약품 분사영역의 확대가 제한적일 수밖에 없다는 문제점이 있다. By the way, another conventional chemical injector is sprayed into the impeller injection port formed between each wing of the impeller, so that the injection area of the chemical is expanded to the circumferential area including the lower direction of the impeller without worrying about the backflow of the treated water. However, due to the structure of the impeller (the structure of the torsion angle of the impeller), the chemical injection zone is inclined to the downward direction of the impeller. Therefore, there is a problem that the expansion of the chemical injection zone is limited.

따라서, 본 발명의 목적은, 약품을 처리수중의 전 영역으로 분사하여 약품이 처리수중에 빠르게 혼합될 수 있는 약품분사기의 임펠러를 제공하는 것이다.
Accordingly, it is an object of the present invention to provide an impeller of a chemical injector in which a chemical is injected into the entire area of the treated water so that the chemical can be quickly mixed in the treated water.

The object is, according to the present invention, the turbine shaft coupled to the rotation axis of the motor and the chemical induction path is formed along the inner center axis, and the inflow that the chemical is supplied from the outside surrounding the turbine shaft to communicate with the chemical induction An impeller coupled to the free end of the turbine shaft of a chemical injector having a port, comprising: an impeller bushing coupled to the free end of the turbine shaft and having at least one chemical injection port formed in a peripheral wall in communication with the chemical induction path; A plurality of impeller wings provided at equal intervals on the outer circumferential surface of the impeller bushing with the chemical injection hole therebetween; It is achieved by the impeller of the chemical injector is formed on the outer surface of the impeller wing having an injection angle enlargement pattern for expanding the injection angle of the drug injected through the chemical injection hole.

여기서, 상기 분사각확대패턴은 상기 각 임펠러날개의 적어도 일 측면에서 외측을 향해 확대되는 부등호형상의 돌출리브 형태로 형성되는 것이 바람직하다. Here, the injection angle expanding pattern is preferably formed in the form of an inequality arc-shaped protrusion rib that extends outward from at least one side of each impeller blade.

그리고, 상기 임펠러부싱을 향하는 상기 분사각확대패턴의 단부영역은 상기 약품분사구의 중심축선에 인접하는 것이 효과적이다. In addition, it is effective that the end region of the injection angle expanding pattern facing the impeller bushing is adjacent to the central axis of the chemical injection hole.

또한, 상기 약품분사구는 임펠러부싱에 인접하는 상기 분사각확대패턴의 단부영역 상하 양측에서 상기 분사각확대패턴의 확대패턴 방향에 평행한 축선을 갖 도록 한 쌍으로 형성될 수 있다. In addition, the chemical injection port may be formed in a pair so as to have an axis line parallel to the direction of the expansion pattern of the injection angle expansion pattern in the upper and lower sides of the end region of the injection angle expansion pattern adjacent to the impeller bushing.

이하에서는 첨부된 도면을 참고하여 본 발명에 대해서 상세하게 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

도 3은 본 발명에 따른 약품분사기의 임펠러 사시도이다. 이 도면에 도시된 바와 같이, 본 발명에 따른 약품분사기의 임펠러(10)는 후술할 터빈축(20)의 자유단부에 결합되는 임펠러부싱(11)과, 임펠러부싱(11)의 외주면에 둘레방향을 따라 등간격으로 마련되는 복수의 임펠러날개(13)와, 임펠러날개(13)의 외표면에 형성되는 분사각확대패턴(15)을 포함한다. 3 is a perspective view of the impeller of the chemical injector according to the present invention. As shown in this figure, the impeller 10 of the chemical injector according to the present invention is an impeller bushing 11 coupled to the free end of the turbine shaft 20 to be described later, and the circumferential direction on the outer peripheral surface of the impeller bushing 11 A plurality of impeller wings 13 provided at equal intervals along the, and the injection angle expanding pattern 15 formed on the outer surface of the impeller wings (13).

임펠러부싱(11)은 볼트(11b) 등에 의해 터빈축(20)의 자유단부에 견고하게 결합되며, 그 둘레벽에는 각 임펠러날개(13)의 사이에 약품분사구(11a)가 관통되어 있다. 이 약품분사구(11a)는 터빈축(20)의 자유단부 영역에 형성된 약품토출구(21)와 동축선상에 위치한다. 여기서, 약품분사구(11a)는 그 축선이 도 3에 도시된 바와 같이, 분사각확대패턴(15)을 향하는 수평을 이루도록 형성될 수 있으며, 도 5에 도시된 바와 같이, 분사각확대패턴(15)의 각도에 평행한 축선을 이루도록 상, 하부에 한 쌍으로 형성될 수도 있다. The impeller bushing 11 is firmly coupled to the free end of the turbine shaft 20 by a bolt 11b or the like, and a chemical injection hole 11a penetrates between the impeller blades 13 through the circumferential wall thereof. This chemical injection port 11a is located coaxially with the chemical discharge port 21 formed in the free end area of the turbine shaft 20. Here, the chemical injection hole (11a) may be formed such that its axis is horizontal to face the injection angle expansion pattern 15, as shown in Figure 3, as shown in Figure 5, the injection angle expansion pattern 15 It may be formed in a pair on the upper, lower so as to form an axis parallel to the angle of).

임펠러날개(13)는 임펠러부싱(11)의 둘레면을 따라 약품분사구(11a)를 사이에 두고 등간격으로 형성된다. 이 임펠러날개(13)는 임펠러부싱(11)과 일체를 이루는 것이 바람직하며, 그 형상과 비틀림각은 다양하게 변경될 수 있다. Impeller wings 13 are formed at equal intervals with the chemical injection hole (11a) between the impeller bushing (11) along the circumferential surface. The impeller wing 13 is preferably formed integrally with the impeller bushing 11, the shape and the torsion angle can be changed in various ways.

한편, 분사각확대패턴(15)은 각 임펠러날개(13)의 적어도 일 측면에서 외측을 향해 확대되는 부등호형상의 돌출된 리브 형태로 형성되는 것이 바람직하다. 이때, 임펠러부싱(11)을 향하는 분사각확대패턴(15)의 단부는 약품분사구(11a)의 중심축선에 인접하는 것이 바람직한데 이는 약품분사구(11a)를 통해 배출되는 약품이 분사각확대패턴(15)의 패턴면을 따라 상하부로 원활하게 확대 분사되도록 유도하기 위함이다. On the other hand, the injection angle magnification pattern 15 is preferably formed in the form of a protrusion rib of an inequality that extends outward from at least one side of each impeller wing (13). At this time, the end of the injection angle expansion pattern 15 toward the impeller bushing 11 is preferably adjacent to the central axis of the chemical injection port (11a), which is the chemical discharged through the chemical injection port (11a) injection angle expansion pattern ( This is to guide the expansion and spraying to the upper and lower smoothly along the pattern surface of 15).

그리고, 약품분사구(11a)가 도 5와 같이 분사각확대패턴(15)과 평행한 축선을 갖도록 형성되는 경우에는 각 약품분사구(11a)는 임펠러부싱(11)에 인접하는 분사각확대패턴(15)의 일측단부 상하 양측에 인접하게 형성되는 것이 약품 분사각이 상하방향으로 확대될 수 있다. When the chemical injection hole 11a is formed to have an axis parallel to the injection angle expansion pattern 15 as shown in FIG. 5, each chemical injection hole 11a has an injection angle expansion pattern 15 adjacent to the impeller bushing 11. Adjacent to the upper and lower sides of one side end of the) may be the chemical injection angle can be extended in the vertical direction.

이러한 약품분사기의 임펠러(10)는 도 4에 도시된 바와 같이, 약품분사기(1)의 터빈축(20) 자유단부에 임펠러부싱(11)이 볼트(11b) 등으로 결합된 상태에서 모터(30)가 회전하면, 터빈축(20)에 부착된 터빈(27)이 압력챔버(40) 입구에서 터빈축(20)과 함께 고속회전하면서, 외부로부터 유입관(50)을 통해 유입포트(60)로 공급되는 약품을 끌어들임과 동시에, 유입포트(60) 내부의 약품을 압력챔버(40) 쪽으로 밀어낸다. 터빈(27)에 의해 압력챔버(40)로 밀려나온 약품이 압력챔버(40) 내부에서의 압력 상승으로 인하여, 다시 터빈축(20)의 약품배출구(25)를 통하여 터빈축(20) 속의 약품유도로(23)를 따라 약품토출구(21)를 통하여 임펠러(10)의 약품분사구(11a)로 배출되면, 임펠러(10)의 회전 원심력에 의해 약품이 임펠러(10)의 둘레방향과 처리수중으로 분사된다. As shown in FIG. 4, the impeller 10 of the chemical injector has a motor 30 in the state where the impeller bushing 11 is coupled to the free end of the turbine shaft 20 of the chemical injector 1 by a bolt 11b or the like. ) Rotates, the turbine 27 attached to the turbine shaft 20 rotates at a high pressure with the turbine shaft 20 at the inlet of the pressure chamber 40, while the inlet port 60 is connected through the inlet pipe 50 from the outside. At the same time attracting the chemicals supplied to the pressure in the inlet port 60, the chemicals to the pressure chamber 40. The chemicals pushed out to the pressure chamber 40 by the turbine 27 are increased in the pressure chamber 40, and thus, the chemicals in the turbine shaft 20 are passed through the chemical outlet 25 of the turbine shaft 20 again. When the drug is discharged to the chemical injection hole 11a of the impeller 10 through the chemical discharge port 21 along the induction path 23, the chemical is discharged into the circumferential direction of the impeller 10 and the treated water by the rotary centrifugal force of the impeller 10.
