Description
本創作係有關一種保護裝置，更特別有關一種防止熔融金屬逆流的冷卻管道保護裝置。This creation relates to a protection device, and more particularly to a cooling pipe protection device that prevents reverse flow of molten metal.
高爐出鐵用開孔機，其鑽頭的冷卻系統需能抵抗高爐內部壓力。當冷卻系統失效時，可能導致高壓熔融鐵水侵入而損傷設備。原有系統自保方法為設置逆止閥，但所在位置是強烈振動與巨大衝擊的區域，閥體極易損壞，因此使冷卻系統無法正常運作。坊間有所謂的燃氣防逆火裝置，但因壓損過大，且阻隔火焰與阻隔高壓熔融鐵水的機制並不相同，因此無法適用。The blast furnace tapping machine has a drilling system that is resistant to the internal pressure of the blast furnace. When the cooling system fails, it may cause high pressure molten iron to invade and damage the equipment. The original system self-protection method is to set the check valve, but the location is the area of strong vibration and huge impact, the valve body is easily damaged, so the cooling system can not operate normally. There is a so-called gas fire-proof device in the workshop, but the pressure loss is too large, and the mechanism for blocking the flame is not the same as the mechanism for blocking the high-pressure molten iron.
有鑑於此，便有需要提出一種方案，以解決上述問題。In view of this, there is a need to propose a solution to solve the above problems.

根據本創作之防止熔融金屬逆流的冷卻管道保護裝置，利用材料特性交互反應達成阻隔效果，裝置無活動零件，構造簡單堅固，可耐受強烈振動與巨大衝擊。此外，本創作之管道保護裝置的壓損小，能讓低溫流體通過，但可阻擋高溫流體，並可應用於管線內流體溫度過高時的阻斷保護。因此，本創作之防止熔融金屬逆流的冷卻管道保護裝置適合安裝於高爐出鐵用開孔機內，於前端防止熔融鐵水侵入其冷卻管道，進而保護開孔機本體。According to the creation of the cooling pipe protection device for preventing reverse flow of molten metal, the material property is interactively reacted to achieve a barrier effect, the device has no moving parts, the structure is simple and firm, and can withstand strong vibration and great impact. In addition, the pipeline protection device of the present invention has a small pressure loss, allows low-temperature fluid to pass, but can block high-temperature fluid, and can be applied to the blocking protection when the fluid temperature in the pipeline is too high. Therefore, the cooling pipe protection device for preventing reverse flow of molten metal in the present invention is suitable for being installed in a tapping machine for blast furnace tapping, preventing molten iron water from intruding into the cooling pipe at the front end, thereby protecting the body of the tapping machine.
為了讓本創作之上述和其他目的、特徵和優點能更明顯，下文將配合所附圖示，詳細說明如下。此外，於本創作之說明中，相同之構件係以相同之符號表示，於此先述明。In order to make the above and other objects, features and advantages of the present invention more comprehensible, the following detailed description will be made in conjunction with the accompanying drawings. In the description of the present invention, the same components are denoted by the same reference numerals and will be described above.
請參照圖1，本創作之防止熔融金屬逆流的冷卻管道保護裝置包含有一管狀的外殼3，固定在一設備管道2內，其中外殼3的截面視設備管道2的內徑來製作。管狀的外殼3具有中空結構，其內部填充有高熔點金屬填充物4與低熔點金屬填充物5，其中高熔點金屬填充物4設置在管狀外殼3的尾段，而低熔點金屬填充物5則設置在管狀外殼3的頭段。外殼3的內部還設置有一中間隔板9，用以隔開高熔點金屬填充物4與低熔點金屬填充物5。外殼3頭端設置有一頭端板8，用以防止低熔點金屬填充物5洩漏出，而外殼3尾端則設置有一尾端板7，用以防止高熔點金屬填充物4洩漏出。Referring to Figure 1, the cooling duct protection device for preventing reverse flow of molten metal comprises a tubular outer casing 3 fixed in a device pipe 2, wherein the cross section of the outer casing 3 is made according to the inner diameter of the equipment pipe 2. The tubular outer casing 3 has a hollow structure filled with a high melting point metal filler 4 and a low melting point metal filler 5, wherein the high melting point metal filler 4 is disposed at the tail end of the tubular outer casing 3, and the low melting point metal filler 5 is It is disposed in the head section of the tubular outer casing 3. An intermediate partition 9 is also provided in the interior of the outer casing 3 for separating the high melting point metal filler 4 from the low melting point metal filler 5. The end of the outer casing 3 is provided with a head end plate 8 for preventing the low-melting metal filler 5 from leaking out, and the tail end of the outer casing 3 is provided with a tail end plate 7 for preventing the high-melting metal filler 4 from leaking out.
根據本創作之防止熔融金屬逆流的冷卻管道保護裝置，其中高熔點金屬填充物4是放置在設備管道2內的低溫側（冷卻側），且其熔點高於高溫流體6的溫度，而低熔點金屬填充物5是放置在設備管道2內的高溫側，且其熔點低於高溫流體6的溫度。另外，頭端板8、尾端板7與中間隔板9係為網狀或多孔板材，並可承受低溫冷卻流體1的壓力。According to the present invention, a cooling pipe protection device for preventing reverse flow of molten metal, wherein the high melting point metal filler 4 is placed on the low temperature side (cooling side) in the equipment pipe 2, and its melting point is higher than the temperature of the high temperature fluid 6, and the low melting point The metal filler 5 is placed on the high temperature side inside the equipment pipe 2, and its melting point is lower than the temperature of the high temperature fluid 6.

在正常情況下，冷卻流體1將高熔點金屬填充物4維持在低溫狀態；而當冷卻流體失效（失壓）並造成高溫流體6倒灌時，低熔點金屬填充物5將被熔化，並隨高溫流體6逆流。熔融的低熔點金屬填充物5遭遇低溫的高熔點金屬填充物4時，會因溫度降低而凝結10，以阻斷高溫流體6繼續逆流（如圖2所示）。Under normal conditions, the cooling fluid 1 maintains the high melting point metal filler 4 at a low temperature; and when the cooling fluid fails (pressure loss) and causes the high temperature fluid 6 to be poured, the low melting point metal filler 5 will be melted and with high temperature. The fluid 6 flows countercurrently. When the molten low-melting metal filler 5 encounters the low-temperature high-melting metal filler 4, it will condense 10 due to the temperature drop to block the high-temperature fluid 6 from continuing to flow back (as shown in FIG. 2).
根據本創作之防止熔融金屬逆流的冷卻管道保護裝置，其中高熔點金屬填充物4與低熔點金屬填充物5為等粒徑球狀顆粒所堆積，孔隙率大，結構紮實，並由外殼3緊密固定。According to the present invention, a cooling pipe protection device for preventing reverse flow of molten metal, wherein the high melting point metal filler 4 and the low melting point metal filler 5 are stacked with spherical particles of equal particle size, have a large porosity, are solid in structure, and are tightly packed by the outer casing 3. fixed.
