Description
본 고안은 상압의 증기양생 또는 일반 레미콘에 적용되는 고강도 시멘트 혼화재의 제조장치에 관한 것이다.The present invention relates to an apparatus for producing high-strength cement admixtures applied to steam curing or general ready-mixed concrete at atmospheric pressure.
특히, 본 고안의 제조장치를 통해 생산되는 혼화재는 플라이 애쉬, 슬래그미분말 등의 산업폐기물계 포졸란(pozzolan) 재료를 주재로 하고, 여기에 무수석고와 팽창제 및 유동화제를 일정량 함유시킴으로 포졸란의 조기 활성과 강도 및 내구성과 유동성의 증진은 물론 건조후의 수축 감소로 품질의 항상성이 유지되는 고품질과 경제성 확보의 2차 시멘트 제품 생산을 위한 제조장치이다.In particular, the admixture produced through the manufacturing apparatus of the present invention is mainly based on industrial waste-based pozzolan materials such as fly ash, slag powder, etc., and contains an amount of anhydrous gypsum, an expanding agent and a fluidizing agent, thereby prematurely activating the pozzolan. It is a manufacturing apparatus for producing high quality and economical secondary cement products that maintains homeostasis of quality by reducing overshrinkage after drying as well as increasing strength, durability and fluidity.
일반적으로, 시멘트 혼화재는 레미콘 등 2차 시멘트 제품의 성능향상을 위해 사용되는 것으로, 주로 시멘트의 사용량을 줄이면서 콘크리트의 고강도 발현, 화학 및 동결융해의 저항성 증대에 따른 내구성 향상, 수화열에 의한 콘크리트의 균열방지와 그에 따른 저발열성 콘크리트의 제조 등을 위해 제공된다.In general, cement admixtures are used to improve the performance of secondary cement products such as ready-mixed concrete. The cement admixture is mainly used for reducing the amount of cement and improving the durability by increasing the strength of concrete, resistance to chemical and freeze-thawing, and It is provided for the prevention of cracking and the production of low heat concrete accordingly.
이러한 시멘트 혼화재는 주로 포졸란계의 산업폐기물인 플라이 애쉬, 슬래그 미분말, 폐제올라이트 등을 사용하여 산업폐기물의 재활용을 도모하면서도 단가의 저감과 콘크리트 제품의 장기강도 및 내구성의 향상을 구현하는데, 이를 제조하기 위해 마련되는 생산설비는 그 낙후성으로 생산성이 매우 낮아 그 교체의 필요성이 매우 절실하였다.These cement admixtures mainly use pozzolan-based industrial wastes such as fly ash, slag fine powder, and waste zeolites to reduce industrial costs and improve long-term strength and durability of concrete products. The production facilities provided for the clinic have very low productivity due to its backwardness, so the necessity of the replacement is very urgent.
즉, 최초 수거된 주 재료의 투입에서 부터 분급 및 혼합가공과 역시 부원료의 투입 및 혼합가공은 물론이고 이들의 계량과 상호 배합 그리고 이송 및 재 처리에 따른 혼합과정이 일련의 연속선상에 있지 못하여 작업시간의 과다 소요와 품질의 균일화를 확보하는데 큰 장해를 초래하여 경제성 및 경쟁력의 약화를 초래하곤 하였다.In other words, the classification and mixing processing from the input of the first collected main materials, and also the input and mixing processing of subsidiary materials, as well as the mixing process according to their weighing, intermixing, transfer and reprocessing are not performed in a series of continuous lines. Too much time and the uniformity of quality have caused great obstacles, resulting in weak economic and competitiveness.
따라서, 상기의 문제점을 해결하기 위해 안출되어진 본 고안은 고품질의 시멘트 혼화재를 제공함에 있어 포졸란 재료의 수집과 부원료의 투입 그리고 이와 관련된 제반 정제과정과 계량 및 혼합, 이송, 저장, 배출 등 각각의 공정이 원활하게 일련 연속적으로 이루어지는 제조장치를 제공함으로서 시멘트의 치환량을 증가시킴과 동시에 공정의 단축과 품질의 항상성 및 신뢰도를 보장하여 2차 시멘트 제품의 제조에 활용될 시 사용자의 만족감 구현이 가능토록 한 제조장치의 제공을 목적으로 한다.Therefore, the present invention devised to solve the above problems is to provide high-quality cement admixtures, and to collect pozzolanic materials and input of subsidiary materials, and all related processes such as refining and weighing, mixing, conveying, storing, and discharging. By providing this seamless series of manufacturing devices, it is possible to increase the amount of substitution of cement and to guarantee the shortening of the process and the homeostasis and reliability of the quality, so that the user's satisfaction can be realized when used in the manufacture of the secondary cement products. An object of the present invention is to provide a manufacturing apparatus.

이하, 첨부된 도면을 참조하여 본 고안의 바람직한 일 실시예를 상세하게 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
먼저, 본 고안을 통해 제조되는 혼화재는 산업폐기물계로 저가의 포졸란 재료인 플라이 애쉬를 수집하여 이를 주재로 한 채 슬래그 미분말과 여기에 포졸란 재료의 조기 활성을 위한 목적의 일환으로 적량의 무수석고가 혼합되고, 각기 소량으로 2차 시멘트 제품인 레미콘 등의 무수축성을 위한 CSA계 팽창제 및 수밀성과 유동성 증진을 위한 리그닌계 유동화제인 리그닌 설폰산염이 혼합되어 제조 생산되는 조성물을 지칭한다.First, the admixture manufactured through the present invention is an industrial waste system, which collects fly ash, which is a low-cost pozzolanic material, and mixes an appropriate amount of anhydrous gypsum as part of the preliminary slag powder and premolar activation of the pozzolanic material. Each of these compounds refers to a composition produced by mixing a small amount of CSA-based expanding agent for shrinkage, such as a ready-mixed concrete, such as a ready-mixed cement product, and lignin sulfonate, which is a lignin-based fluidizing agent for enhancing water tightness and fluidity.
이를 위해 본 고안의 제조장치는 화력발전소 등에서 발생되는 폐기물로서 타지않은 석탄분인 플라이 애쉬를 수집하여 이를 벌크 트럭 등의 운송수단을 통해 사일로우 형식의 제 1저장부(1)에 투입 저장한 후 이를 분말도(BLAINE) 4000㎠/g 이상의 고분말로 정제하기 위한 분급기(2)로 투입될 수 있게 하되, 작업자에 의한 임의의 투입량 조절이 가능할 수 있게 한다.To this end, the manufacturing apparatus of the present invention collects fly ash, which is unburned coal, as waste generated from a thermal power plant, and stores it in a silo type first storage unit 1 through a bulk truck or the like. This can be added to the classifier (2) for refining the powder (BLAINE) to a high powder of 4000 cm2 / g or more, it is possible to control the amount of input by the operator.
상기와 같이 분급기(2)를 통해 정제된 플라이 애쉬는 이송로를 통해 원심분리기(3)로 투입되고, 이러한 플라이 애쉬의 주재와는 별도로 슬래그 미분말, 무수석고, 팽창제 및 유동화제 등의 부원료는 역시 사일로우 형식의 제 2저장부(4)를 통해 투입 공급되어져 각기 별도로 저장된 채 적량 배출될 수 있도록 하는데, 배출된 부원료의 투입량 산정은 스케일 호퍼로 마련되는 제 1계량기(5)를 통해 계량된 후 고른 혼합을 위해 고효율의 제 1혼합기(6)로 넘겨져 혼합 처리된다.The fly ash purified through the classifier (2) as described above is introduced into the centrifuge (3) through a transfer path, and separate raw materials such as fine slag powder, anhydrous gypsum, swelling agent and fluidizing agent, apart from the main body of the fly ash, Also, it is supplied through the second storage part 4 of the silo type so that each of the separately stored quantities can be discharged, and the input amount of the discharged subsidiary material is measured through the first meter 5 provided with the scale hopper. It is then passed to the high efficiency first mixer 6 for even mixing, and then mixed.
이후, 상기 제 1혼합기(6)를 통한 혼합재료는 이송수단인 제 1버킷 엘리베이터(7)를 통해 운반되어 제 3저장부(8)에 저장된 채 대기된다.Thereafter, the mixed material through the first mixer 6 is transported through the first bucket elevator 7, which is a conveying means, and waits while being stored in the third storage 8.
한편, 상기 원심분리기(3)를 거친 플라이 애쉬는 그 투입량 산정을 위해 마련되는 임펙트 플로우 메터인 제 2계량기(9)를 통해 계량된 후 대기하고 있던 전술한 제 3저장부(8)를 거친 혼합재료가 계량과정을 거쳐 상호 일정한 비율로 고루 배합될 수 있게 제 2혼합기(10)를 통과하게 되고, 이러한 배합물은 이송수단인 제 2버킷 엘리베이터(11)를 통해 운반되어져 배합물의 재 혼합을 위해 스크류 방식을 채택하고 있는 제 3혼합기(12)로 투여된 후 완성된 조성물로서 배출되는 것으로, 이와 같이 조성되는 본 발명의 조성물은 제 4저장부(13)로 이송되어 대기하면서 배출슈트(14)를 통해 적절히 외부로 출하될 수 있도록 배려되는 것이다.On the other hand, the fly ash that passed through the centrifuge (3) is mixed through the above-described third storage section (8), which was measured after waiting through the second meter (9), which is an impact flow meter provided for the calculation of the input amount. The material is passed through the second mixer 10 so that the material is evenly blended at a constant rate through the weighing process, and the compound is conveyed through the second bucket elevator 11, which is a conveying means, to remix the compound. It is discharged as a finished composition after being administered to the third mixer 12 employing the method, the composition of the present invention is thus transferred to the fourth storage unit 13 while waiting for the discharge chute 14 It will be considered to be properly shipped to the outside.
이와 같은 본 고안의 제조장치에 따르면, 고품질의 시멘트 혼화재를 제공하는 각각의 공정이 하나의 단일화 된 시스템을 통해 원료의 투입에서부터 일률적인 제품 출하가 가능해져 공정의 현저한 단축과 품질의 항상성 그리고 사용자의 신뢰도를 고루 만족하게 되어 경제적인 유용성은 물론 경쟁력의 충분한 강화를 기대할 수 있다는 유용성을 제공한다.According to the manufacturing apparatus of the present invention as described above, each process to provide high quality cement admixtures can be shipped from raw materials through a single unified system, resulting in a significant reduction in the process, homeostasis of quality, and Reliability is satisfied evenly, providing economic usefulness as well as good competitiveness.
이하, 본 고안을 특정의 바람직한 실시예에 관련하여 도시하고 설명하였지만 이하의 청구범위에 의해 마련되는 본 고안의 정신이나 분야를 이탈하지 않는 한도내에서 다양한 개조와 변화가 가능할 수 있음은 물론이다.Hereinafter, the present invention has been illustrated and described with reference to certain preferred embodiments, but various modifications and changes may be made without departing from the spirit or the scope of the present invention provided by the following claims.
