이하에서는 본 발명에 따른 패각을 이용한 이온화 칼슘제 제조방법의 바람직한 실시 예를 상세히 설명한다.Hereinafter, preferred embodiments of the process for preparing an ionized calcium salt using the shell according to the present invention will be described in detail.
먼저, 도 1에 도시한 바와 같이 본 발명에 따른 패각을 이용한 칼슘제 제조방법은 크게 원료투입공정(1), 이물질제거공정(2), 세정공정(3), 건조공정(4), 예열공정(5), 소성공정(6), 냉각공정(7), 분쇄공정(8), 포장공정(9)이 연속적으로 이루어진다. As shown in FIG. 1, the method of manufacturing a calcium salt using a shell according to the present invention is roughly divided into a raw material input step 1, a foreign
상기의 원료투입공정(1)에서 원료란 이온화 칼슘제를 생산하기 위한 원재료인 굴, 고막, 바지락, 소라 등의 껍데기인 패각(貝殼)을 말한다. In the above-mentioned raw material input step (1), the raw material refers to shells such as oyster, eardrum, clam, and sole which are raw materials for producing an ionized calcium preparation.
이물질제거공정(2)은 수거된 다량의 패각으로부터 철 조작이나 기타 이물질(병 조각, 비닐, 끈, 대나무 등)을 제거하기 위한 것으로, 일례로 철 조작의 경우 자성체를 이용하여 제거하고, 기타 이물질의 경우 컨베이어를 통한 이송시 작업자가 육안으로 점검하여 제거하거나 진동선별기를 이용하여 제거한다.The foreign substance removal step (2) is for removing iron manipulation or other foreign matter (bottle piece, vinyl, string, bamboo, etc.) from a large amount of shells collected. For example, In the case of transporting through conveyor, the operator should visually check and remove or remove by using a vibration separator.
세정공정(3)은 패각에 붙은 개흙(뻘)이나 모래, 유기물 등을 제거하여 순수한 패각만을 얻기 위한 것으로, 일례로 패각을 경사식의 회전 세척통에 연속적으로 투입 회전시키면서 세정하고 컨베이어를 통한 이송시 물을 분사하여 재차 세정함으로써 패각에 붙은 개흙이나 모래, 유기물 등을 제거한다.The washing process (3) is for removing only the pure shell by removing soil, sand, organic matter and the like attached to the shell. For example, the shell is cleaned while continuously rotating the shell in a slantwise rotary washing container, Water is sprayed and washed again to remove clay, sand and organic matter from the shell.
건조공정(4)은 세정된 패각의 표면 물기를 제거하기 위한 것으로, 일례로 100~150℃의 열풍이 주입되는 건조 터널을 통과시켜 수분을 제거한다. 이는 소성공정시 잔존하는 물기에 의해 노(爐) 내에 증기가 차는 것을 방지함으로써 노 내부를 고온상태로 유지하기 위함이다. The drying step (4) is for removing the surface moisture of the washed shell, for example, through a drying tunnel into which hot air of 100 to 150 ° C is injected to remove moisture. This is to keep the inside of the furnace at a high temperature by preventing steam from getting into the furnace due to the residual moisture during the baking process.
상기의 공정 중 필요에 따라 이물질제거공정(2a)을 추가할 수 있다. 예컨대, 세정공정(3) 및 건조공정(4)의 완료로 개흙이나 모래, 유기물의 제거로 패각과 이물질이 명확하게 분리되는데, 이때 컨베이어를 통한 이송시 작업자가 육안으로 점검하여 제거하거나 진동선별기를 이용하여 잔존하는 이물질을 재차 제거한다.In the above process, the foreign
예열공정(5)은 소성로(11)로부터 배출된 폐열을 회수하여 패각을 예열하기 위한 것으로, 패각을 일정온도로 예열하여 소성로(11)로 투입함으로써 에너지 효율을 높일 수 있다. The preheating step 5 is for recovering the waste heat discharged from the firing furnace 11 to preheat the shell. The preheating of the shell to a predetermined temperature and the introduction into the firing furnace 11 can increase the energy efficiency.
소성공정(6)은 예열된 패각을 고온으로 소성하여 칼슘을 이온화시키기 위한 것으로, 소성로(11)의 회전속도, 패각 투입량, 소성온도의 제어를 통해 칼슘의 순도에 따른 비료, 식품, 공업용의 이온화 칼슘제를 각각 따로 제조한다.The firing step (6) is for firing the preheated shell at a high temperature to ionize the calcium. By controlling the rotation speed of the firing furnace (11), the amount of shell input and the firing temperature, Calcium preparations are prepared separately.
냉각공정(7)은 소성된 고온의 패각을 상온으로 급랭시켜 고온상태에서 대기와의 접촉에 따른 산화진행률을 낮추기 위한 것으로, 일례로 물 재킷이 마련된 냉각기를 경유하도록 하고 냉각기 내의 공기를 강제 흡입하여 냉기와 열교환시킴으로써 고온의 패각을 급랭시킨다.The cooling step (7) is to cool the baked high-temperature shell to room temperature to lower the oxidation progress rate due to contact with the atmosphere at a high temperature. For example, by making the cooler provided with a water jacket pass, The hot shell is quenched by exchanging heat with cold air.
이후, 소성되고 냉각된 패각을 분쇄기를 이용하여 제품 특성에 맞게 다양한 크기로 분쇄하고(분쇄공정; 8), 이를 포장함으로써 이온화 칼슘제의 제조를 완료한다(포장공정; 9). Thereafter, the baked and cooled shell is pulverized (pulverizing process) 8 to various sizes according to the product characteristics using a pulverizer, and then the pulverized product is packaged to complete the production of the ionized calcium product (packaging process).
다음은, 본 발명의 주요공정인 예열공정(5)과 소성공정(6)을 수행하기 위한 소성장치에 관하여 설명한다.Next, the firing apparatus for carrying out the preheating step (5) and the firing step (6) which are the main processes of the present invention will be described.
본 발명의 제조공정에 적용되는 소성장치는 하향 경사지게 설치되고 구동장치(M)에 의해 회전하며 연속적으로 투입되는 패각을 교반시키면서 이송하고 소성할 수 있도록 원통형의 소성로(11)가 구비된다.The firing apparatus applied to the manufacturing process of the present invention is provided with a cylindrical firing furnace 11 so as to be downwardly inclined and to be conveyed and fired while agitating the shell which is continuously rotated by the drive unit M and rotated.
또, 소성로(11)의 입구 측에는 패각의 투입량을 조절하기 위한 피더(feeder; 12)가 설치되고, 피더(12)로부터 공급된 패각을 소성로(11)로 안내하기 위한 공급관(13)이 설치되며, 소성로(11)의 입구 측을 감싸 소성로(11)로부터 배출된 폐열을 회수하고 공급관(13) 측으로 유도하여 패각을 예열하기 위한 회수관로(14)가 설치된다. A
그리고 소성로(11)의 출구 측에는 패각 소성에 필요로 하는 열원을 제공하되 소성온도를 조절하기 위한 가열수단(일례로, LPG 버너 등; 15)이 설치되고, 소성로의 출구 하단에 소성 후 배출되는 패각을 받아들이기 위한 호퍼(16) 및 호퍼(16)로부터 배출된 패각을 냉각기 측으로 이송하기 위한 컨베이어(17)가 설치된다.A heating means (for example, LPG burner or the like) 15 for controlling the firing temperature is provided on the outlet side of the firing furnace 11 to provide a heat source required for the firing of the shell, And a
상기의 기술적 구성에서, 소성로(11)는 출구 측이 입구 측보다 5°정도 하향 경사지게 설치된다. 이에 따라, 소성로(11)의 입구 측으로 투입된 패각은 소성로(11)가 회전함에 따라 자연스럽게 출구 측으로 교반 이송되고, 이송과정에서 소성이 이루어진다.In the above technical arrangement, the firing furnace 11 is installed such that its outlet side is inclined downward by about 5 degrees from the inlet side. Accordingly, the shell introduced into the inlet side of the firing furnace 11 is naturally conveyed to the outlet side as the firing furnace 11 rotates, and firing is performed in the course of the transfer.
예컨대, 소성로(11)는 내화벽돌에 의해 단열처리되고 그 길이가 18,000㎜, 그 내경이 900㎜로서, 소성로(11)의 회전속도가 40~50rpm, 패각의 투입량이 1,000kg/hr, 소성온도가 900~1,100℃인 경우 패각이 소성로(11) 내를 20~30분 체류함으로써 칼슘의 순도가 75~95%인 비료용 이온화 칼슘제를 제조할 수 있게 된다. For example, the firing furnace 11 is thermally insulated by refractory bricks and has a length of 18,000 mm and an inner diameter of 900 mm. The firing furnace 11 has a rotational speed of 40 to 50 rpm, an input amount of shell of 1,000 kg / Is 900 to 1,100 ° C, the shell is allowed to stand in the calcining furnace 11 for 20 to 30 minutes, thereby making it possible to produce an ionized calcium agent for fertilizer having a purity of calcium of 75 to 95%.
또한, 소성로(11)의 회전속도가 35~40rpm, 패각의 투입량이 500kg/hr, 소성온도가 1,100~1,200℃인 경우 패각이 소성로(11) 내를 30~45분 체류함으로써 칼슘의 순도가 95~99%인 식품용 이온화 칼슘제를 제조할 수 있게 된다.When the rotation speed of the firing furnace 11 is 35 to 40 rpm, the amount of the shell is 500 kg / hr, and the firing temperature is 1,100 to 1,200 ° C., the shell stays in the firing furnace 11 for 30 to 45 minutes, To < RTI ID = 0.0 > 99% < / RTI >
그리고 소성로(11)의 회전속도가 30~35rpm, 패각의 투입량이 300kg/hr, 소성온도가 1,200℃ 이상인 경우 패각이 소성로(11) 내를 45~90분 체류함으로써 칼슘의 순도가 99% 이상인 공업용 이온화 칼슘제를 제조할 수 있게 된다.When the rotation speed of the firing furnace 11 is 30 to 35 rpm, the amount of the shell is 300 kg / hr, and the firing temperature is 1,200 ° C. or more, the shell stays in the firing furnace 11 for 45 to 90 minutes, An ionized calcium agent can be produced.
즉, 본 발명은 소성로(11)의 회전속도, 패각 투입량, 소성온도를 제어하여 연속공정하에서 칼슘함량에 따른 비료, 식품, 공업용의 이온화 칼슘제를 각각 따로 제조할 수 있다는 특징이 있다. That is, the present invention is characterized in that it is possible to separately produce the ionized calcium agent for fertilizer, food, and industrial according to the calcium content under the continuous process by controlling the rotational speed, the shell input amount, and the firing temperature of the firing furnace 11.
