Description

냉각성능이 향상된 알갱이 및 분체 이송용 스크류 컨베이어{COOLING ABILITY ENHANCED SCREW CONVEYOR FOR TRANSFERING POWDER}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screw conveyor for conveying granules and powders having improved cooling performance,

본 발명은 냉각성능이 향상된 알갱이 및 분체 이송용 스크류 컨베이어에 관한 것으로, 보다 상세하게는 고온의 분체 영향을 직접 받는 스크류 컨베이어이 하측 커버 구조를 개선하여 냉각성능을 향상시킴과 동시에 열변형을 방지하여 설비 가동효율을 높이도록 한 냉각성능이 향상된 알갱이 및 분체 이송용 스크류 컨베이어에 관한 것이다.
The present invention relates to a screw conveyor for conveying granules and powders having improved cooling performance, and more particularly, to a screw conveyor for conveying a powder conveyed by a screw conveyor which is directly affected by a high temperature powder to improve a cooling function, And more particularly to a screw conveyor for conveying granules and powders having improved cooling performance for increasing the operation efficiency.

일반적으로, 스크류 컨베이어는 U자형의 트로프 또는 원통 케이싱내에서 나선을 회전시켜 반송물을 밀어보내는 이송수단 중 하나이다.Generally, a screw conveyor is one of conveying means for pushing a conveyed object by rotating a spiral in a U-shaped trough or a cylindrical casing.

이러한 스크류 컨베이어는 각종 산업현장에서 고체를 포함한 주로 알갱이 및 분체(Powder)를 이송하는데 많이 활용된다.Such a screw conveyor is widely used for conveying mainly granules and powders including solids in various industrial fields.

특히, 스크류 컨베이어는 화력발전소나 소각로 등에서 연료를 소각시킨 후 남은 재(Ash)를 이송하는데 효과적이다.In particular, a screw conveyor is effective in transporting ashes left after incinerating fuel in a thermal power plant or an incinerator.

이는 발전소나 소각로의 하부로 낙하되는 재의 경우 대략 900℃ 이르는 고온 상태이므로 이를 받아 냉각하면서 특정 지점으로 배출하는데 스크류 컨베이어가 적합하기 때문이다.This is because the material falling down to the bottom of the power plant or the incinerator is in a high temperature state of about 900 ° C, so a screw conveyor is suitable for discharging to a specific point while cooling it.

이와 관련하여, 등록실용 제0153459호, 공개실용 제1999-0000262호 등의 기술들이 개시되어 있다.In this regard, techniques such as the registration application No. 0153459 and the publication application No. 1999-0000262 are disclosed.

보통, 재를 이송하는 스크류 컨베이어는 도 1의 예시와 같이 경사 설치되는데, 이는 대부분 발전소 혹은 소각로의 재 배출구가 바닥에 근접해 있으므로 수평이동이 어려워 12°정도 경사지게 배치되는 것이 일반적이다.Usually, the screw conveyor for conveying the ash is installed in an oblique manner as shown in the example of Fig. 1, and it is generally arranged to be inclined at about 12 degrees because it is difficult to horizontally move because the outlet of the power plant or incinerator is close to the bottom.

또한, 이송할 재는 대략 900℃에 이르는 고온이기 때문에 그 상태 그대로 이송할 경우 스크류파이프(10) 자체는 물론 그 외주면에 나선형으로 고정된 스크류플라이트(12)의 열변형이 유발되어 스크류 회전이 불능 상태에 빠지므로 이를 방지하기 위해 스크류파이프(10) 내부는 냉각수가 인출입되도록 구성된다.Since the material to be transferred is a high temperature of about 900 ° C, when the screw feed is carried in the state as it is, thermal deformation of the screw fly 10 fixed to the screw pipe 10 itself as well as its outer circumferential surface is caused, The inside of the screw pipe 10 is configured so that the cooling water is drawn in and out.

그리하여, 이송 초입에서 대략 900℃를 유지하던 재는 배출단에서 대략 50℃ 내외로 냉각된 상태로 배출되게 된다.Thus, the ash kept at about 900 캜 at the beginning of the transfer is discharged in a cooled state at about 50 캜 at the discharge end.

여기에서, 도면중 미설명 부호 '32'는 리브, '34'는 지지판이다.In the drawings, reference numerals 32 and 33 denote a rib and a support plate, respectively.

한편, 도 2의 도시와 같이, 고온의 분체가 낙하 투입되는 투입구(14)가 형성된 스크류파이프(10)의 하단부에는 고온의 분체로부터 전달된 고열이 동력원(30)을 비롯한 축계에 미치는 영향을 줄이면서 스크류파이프(10)의 하단부를 밀폐하여 냉각수 순환구조를 갖추도록 하는 커버(40)가 마련된다.On the other hand, as shown in FIG. 2, the high temperature transferred from the high-temperature powder has no influence on the shaft system including the power source 30 at the lower end portion of the screw pipe 10 in which the inlet 14 for dropping the high- And a cover 40 for sealing the lower end of the screw pipe 10 to provide a cooling water circulation structure is provided.

그런데, 종래 커버(40)는 단순한 원판상의 부재로서, 일종의 블라인드 커버(Blind Cover)이기 때문에 열 차단 효과가 높지 못하였다.However, since the conventional cover 40 is a simple disc-shaped member and is a kind of blind cover, the heat shielding effect is not high.

특히, 상기 커버(40)가 있는 위치는 900℃에 이르는 고열을 함유한 분체, 주로 재(ash)가 직접 낙하하면서 상시 유지되는 부위이기 때문에 스크류파이프(10) 내부를 순환하는 냉각수 만으로는 냉각성능을 향상시킬 수 없다.Particularly, since the position where the cover 40 is located is a portion that is maintained at all times while the powder containing high heat up to 900 ° C, mainly ash, is directly dropped, cooling water circulating inside the screw pipe 10 Can not improve.

때문에, 장시간 사용시 고열이 커버(40) 쪽으로 집중되고, 외부로 전도되면서 동력원(30)은 물론 동력원(30)과 연결된 축계에 열변형을 일으켜 동작 불량, 설비 트러블 등 많은 문제들을 야기시키게 된다.
Therefore, when the heater is used for a long time, the high temperature is concentrated toward the cover 40 and is conducted to the outside, causing thermal deformation in the shafts connected to the power source 30 as well as the power source 30, resulting in many problems such as malfunctions and facility troubles.

본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 재와 같은 분체, 특히 고온의 분체를 이용하는 스크류 컨베이어에서 고온의 분체가 직접 낙하 유입되는 부위에 설치된 커버 구조를 개량하여 냉각성능을 향상시킴으로써 후속 설치된 동력원과 축계의 열변형을 막을 수 있도록 한 냉각성능이 향상된 알갱이 및 분체 이송용 스크류 컨베이어를 제공함에 그 주된 목적이 있다.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems in the prior art, and it is an object of the present invention to provide a cover structure in which a high temperature powder is directly dropped in a powder conveyor such as ash, The present invention provides a screw conveyor for conveying a granule and a powder, which is improved in cooling performance and capable of preventing thermal deformation of a subsequent power source and a shaft system by improving cooling performance.

본 발명은 상기한 목적을 달성하기 위한 수단으로, 내부에는 냉각수가 순환되는 구조를 갖춘 스크류샤프트; 상기 스크류샤프트와 동심원을 이루면서 간격이 유지된 채 고정되고, 외주면에는 나선형 스크류플라이트가 고정된 스크류파이프;를 포함하고, 경사 배치되어 고온의 분체를 이송하는데 사용되는 스크류 컨베이어에 있어서; 상기 고온의 분체가 낙하 유입되는 스크류파이프의 하단은 커버에 의해 밀폐되며; 상기 커버에는 일측 하부를 통해 유입된 냉각수가 타측 상부를 통해 배출되도록 설계된 냉각쟈켓이 일체로 구성된 것을 특징으로 하는 냉각성능이 향상된 알갱이 및 분체 이송용 스크류 컨베이어를 제공한다.In order to achieve the above-mentioned object, the present invention provides a scroll fluid machine comprising: a screw shaft having a structure in which cooling water is circulated; And a screw pipe fixed on the outer circumferential surface of the screw shaft and spaced from the screw shaft, the screw pipe being fixed to the outer circumferential surface of the screw pipe, wherein the screw pipe is inclined to be used for conveying high temperature powder. The lower end of the screw pipe into which the hot powder falls is sealed by the cover; And a cooling jacket designed to discharge the cooling water introduced through one side lower portion to the cover through the upper portion of the other side is integrally formed.

이때, 상기 냉각쟈켓의 내부에는 상하방향으로 간격을 둔 판 형상의 냉각수가이드 다수개가 서로 교호되게 배치 고정되어 냉각수유로를 구성하되, 상기 냉각수가이드에는 다수개의 투수공이 더 형성된 것에도 그 특징이 있다.
At this time, a plurality of plate-shaped cooling water guides spaced apart in the up-and-down direction are arranged and fixed interchangeably in the cooling jacket so as to constitute a cooling water flow path, and the cooling water guide also has a plurality of water-permeable holes.

본 발명에 따르면, 고온의 분체를 이용하는 스크류 컨베이어에서 스크류파이프의 하부측을 밀폐하는 커버 구조를 개선하여 냉각기능을 구현함으로써 냉각성능을 향상시키고, 동력원 및 축계 열변형을 막아 설비의 장수명화를 달성하는 효과를 얻을 수 있다.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

또한, 본 발명의 개념에 따른 실시예는 다양한 변경을 가할 수 있고 여러 가지 형태를 가질 수 있으므로, 특정 실시예들은 도면에 예시하고 본 명세서에 상세하게 설명하고자 한다. 그러나, 이는 본 발명의 개념에 따른 실시예들을 특정한 개시 형태에 한정하려는 것이 아니며, 본 발명의 사상 및 기술 범위에 포함되는 모든 변경물, 균등물 내지 대체물을 포함하는 것으로 이해되어야 한다.In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

본 발명에 따른 알갱이 및 분체 이송용 스크류 컨베이어는 U자형의 트로프 또는 원통 케이싱을 포함하지만, 설명의 편의를 위해 본 발명에서는 이들 트로프 또는 케이싱을 생략하기로 한다.The screw conveyor for conveying granules and powders according to the present invention includes a U-shaped trough or a cylindrical casing, but these troughs or casings are omitted in the present invention for convenience of explanation.

도 3에 도시된 바와 같이, 분체, 특히 고온의 분체를 이송하는데 사용되는 스크류 컨베이어는 기본적으로 외주면에 나선형 스크류플라이트(12, 도 1 참고)를 구비한 스크류파이프(10)와, 상기 스크류파이프(10) 내부를 관통하여 회전축을 형성하는 스크류샤프트(20, 도 1 참고)를 포함하여 구성된다.As shown in FIG. 3, the screw conveyor used for conveying the powder, in particular, the high-temperature powder is basically composed of a screw pipe 10 having a spiral screw flight 12 (see FIG. 1) And a screw shaft 20 (see FIG. 1) which penetrates the inside of the screw shaft 10 to form a rotating shaft.

그리고, 상기 스크류파이프(10)의 내부 및 스크류샤프트(20)의 내부는 냉각쟈켓을 구성하여 약 900℃의 분체, 이를 테면 애쉬(재)를 피딩하여 이송할 때 고열의 재를 냉각시키게 된다.The inside of the screw pipe 10 and the inside of the screw shaft 20 constitute a cooling jacket to cool the high-temperature ash when the ash (reflux) is fed and conveyed at about 900 ° C.

한편, 상기 스크류파이프(10)의 하단부에는 고온의 분체가 낙하 투입되는 투입구(14)가 구비되며, 상기 투입구(14)가 형성된 스크류파이프(10)의 단부에는 커버(40)가 설치되어 하부를 밀폐하고, 이를 관통하여 축계(50) 및 동력원(30)이 설치되어 상기 스크류샤프트(20)와 연결된다.The lower end of the screw pipe 10 is provided with a charging port 14 through which a high temperature powder is dropped and a cover 40 is installed at an end of the screw pipe 10 having the charging port 14, And a shaftsystem 50 and a power source 30 are installed through the shaft shaft 20 to be connected to the screw shaft 20.

이와 같은 구조를 갖는 스크류 컨베이어에서, 본 발명은 상기 커버(40)에 냉각쟈켓(70)을 더 구비하여 커버(40) 자체에도 냉각기능을 갖도록 함으로써 분체로부터 전달된 고열이 상기 축계(50) 및 동력원(30) 쪽으로 전달되지 않도록 하여 열변형을 막고, 설비의 장수명화를 달성하도록 구성된다.In the screw conveyor having such a structure, the present invention further includes a cooling jacket 70 on the cover 40 so that the cover 40 itself has a cooling function, so that the high heat transferred from the powder is transferred to the shaft system 50 and / Is prevented from being transmitted to the power source (30), thereby preventing thermal deformation and achieving longevity of equipment.

좀 더 구체적으로, 도 4의 (a)에 도시된 바와 같이, 커버(40)의 외측면, 즉 축계(50)와 동력원(30)이 접속되는 부분 쪽에 냉각쟈켓(70)이 설치된다.More specifically, as shown in Fig. 4 (a), a cooling jacket 70 is provided on the outer surface of the cover 40, that is, on the side to which the power system 30 and the shaftsystem 50 are connected.

상기 냉각쟈켓(70)은 일종의 냉각챔버로서 내부가 비어 있는 중공형 박스타입이며, 중앙은 스크류샤프트(20)와 축계(40)가 연결되어야 하므로 그 부분을 제외한 나머지 부분이 밀폐된 챔버 형태를 이룬다.The cooling jacket 70 is a hollow box type in which the inside of the cooling jacket is hollow and the screw shaft 20 and the shafting system 40 are connected at the center so that the remaining part except for the cooling jacket 70 forms a sealed chamber .

그리고, 냉각효율을 높이기 위해 냉각쟈켓(70)의 일측 하부에 냉각수인렛(72)이 설치되고, 반대쪽 상부에 냉각수아웃렛(74)이 설치되어 냉각수가 냉각쟈켓(70)의 하부 일측으로 공급된 후 내부에 채워진 다음 상부 일측으로 배출됨으로써 냉각효율을 높이게 된다.In order to increase the cooling efficiency, a cooling water inlet 72 is provided at a lower portion of one side of the cooling jacket 70 and a cooling water outlet 74 is provided at the opposite upper side to supply cooling water to one side of the lower portion of the cooling jacket 70 And then discharged to one side of the upper part, thereby enhancing the cooling efficiency.

즉, 통상 물은 높은 곳에서 낮은 곳으로 흐르지만, 본 발명에서는 그 역방향으로 강제 공급함으로써 물이 곧바로 빠져나가지 않고 냉각쟈켓(70) 내부에 완전히 충만된 다음에 일정 수위에 이르렀을 때 배출되기 때문에 그만큼 냉각성능이 향상되게 된다.In other words, although water flows from a high place to a low place in the present invention, water is forcedly supplied in the opposite direction in the present invention so that water is not immediately discharged but is completely filled in the cooling jacket 70 and then discharged when the water level reaches a certain level And the cooling performance is improved accordingly.

이에 더하여, 다른 변형예를 더 가질 수 있는데, 이를 테면 도 4의 (b)와 같이, 상기 냉각쟈켓(70)의 내부에는 판상의 냉각수가이드(76)가 더 형성될 수 있다.4 (b), the cooling jacket 70 may further include a cooling water guide 76 in the form of a plate.

상기 냉각수가이드(76)는 앞서 설명하였듯이 판상의 부재이며, 다수의 부재가 상하방향으로 서로 간격을 두고 엇갈리게 설치되어 냉각수가 흘러갈 수 있는 냉각수유로(G)를 구성하게 된다.As described above, the cooling water guide 76 is a plate-shaped member, and a plurality of members are provided in a staggered manner with a gap therebetween in the vertical direction to constitute a cooling water passage G through which cooling water can flow.

또한, 상기 냉각수가이드(76)는 크기 전체에 걸쳐 일정크기의 투수공(78)이 다수 형성된다.In addition, the cooling water guide 76 has a plurality of water holes 78 having a predetermined size over the entire size thereof.

따라서, 냉각수인렛(72)을 통해 유입된 물의 일부는 냉각수가이드(76)에 의해 상하로 구획 형성된 공간인 냉각수유로(G)를 통해 흘러가고, 동시에 다수의 투수공(78)을 통해서도 직접 상승 분출하게 되므로 결국 물의 흐름이 교번되면서 혼합, 교반되기 때문에 냉각수가이드(76)와 접촉하는 표면적이 넓어질 뿐만 아니라, 유속이 느려지게 되어 냉각효과를 극대화시키게 된다.Therefore, a part of the water introduced through the cooling water inlet 72 flows through the cooling water passage G, which is a space formed by the cooling water guide 76, which is a space defined by the cooling water guide 76. At the same time, As a result, the water flow is alternately mixed and stirred so that the surface area contacting the cooling water guide 76 is widened, and the flow rate is slowed, thereby maximizing the cooling effect.

이와 같이, 본 발명에 따른 커버(40) 냉각구조는 기존에 전혀 찾아볼 수 없던 개념으로 커버(40)에 까지 냉각기능을 구현함으로써 고열이 발생되는 부위를 효과적으로 냉각시켜 설비의 열변형을 완벽하게 방지할 수 있게 된다.
As described above, according to the cooling structure of the cover 40 according to the present invention, the cooling function is implemented up to the cover 40 by a concept that has not been found at all before. By effectively cooling the area where the high temperature is generated, .
