钢包是炼钢的重要设备之一，其使用寿命的长短对企业的生产使用成本有着直接的影响。目前所使用的钢包的结构为：包括钢壳，在钢壳的底部设置有透气砖，钢壳中设置有用以保护透气砖的护砖，透气砖与带有底吹管快换接头的进气管道相连通。工作时，将进气管道上的底吹管快换接头与氩气储气罐的底吹管道相对接，这样氩气储气罐中的氩气等惰性气体会通过透气砖的透气孔吹入钢包，从而对钢包中钢水进行充分搅拌，使添加在钢水的各种材料能快速均匀地熔化，以达到去除有害杂质、提高钢水洁净度的目的。目前所使用的钢包的缺点是：当钢包不需要再吹入氩气而直接快速拔出底吹管道时，透气砖的透气孔内会产生负压，在负压的作用下钢包中的钢水易被吸入透气砖的透气孔中，被吸入透气孔中的钢水易冷凝而堵塞透气孔，严重影响了底吹效果，导致钢包易因透气砖的透气孔被堵而报废，从而大大缩短了钢包的使用寿命。 Ladle is one of the important equipment for steelmaking, and its service life has a direct impact on the production and use cost of the enterprise. The structure of the currently used ladle is: including a steel shell, a breathable brick is arranged at the bottom of the steel shell, a protective brick is arranged in the steel shell to protect the breathable brick, the breathable brick and the air inlet pipe with a quick change joint of the bottom blowing pipe connected. When working, connect the quick-change joint of the bottom blowing pipe on the intake pipe to the bottom blowing pipe of the argon gas storage tank, so that the argon and other inert gases in the argon gas storage tank will be blown into the ladle through the vent hole of the ventilation brick , so that the molten steel in the ladle is fully stirred, so that various materials added to the molten steel can be melted quickly and evenly, so as to achieve the purpose of removing harmful impurities and improving the cleanliness of the molten steel. The disadvantage of the currently used steel ladle is that when the bottom blowing pipe is directly and quickly pulled out of the ladle without blowing in argon gas, negative pressure will be generated in the air holes of the ventilating brick, and the molten steel in the ladle is easily Sucked into the air holes of the air bricks, the molten steel sucked into the air holes is easy to condense and block the air holes, which seriously affects the bottom blowing effect, and the ladle is easily scrapped due to the blocked air holes of the air bricks, thus greatly shortening the life of the ladle. service life.

具体实施方式 Detailed ways
下面结合附图和具体实施例对本实用新型作进一步说明。 Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
如图1所示，所述的防渗堵冶炼钢包，包括： 底部设置有透气砖1的钢壳2，在钢壳2上设置有储气包3，透气砖1通过第一连接管道4与储气包3的出口相连通，储气包3的进口通过第二连接管道5与底吹管快换接头6相连通，在第二连接管道5上设置有单向截止阀7，所述单向截止阀7只允许气体沿第二连接管道5进入储气包3，所述储气包3的体积与钢壳2的体积之间的比值范围为0.00007-0.00009，在本实施例中，所述储气包3的体积与钢壳2的体积之间的比值为0.00008，这种体积大小的储气包3即能更好地避免钢壳中的钢水渗入透气砖1的透气孔，又能最大幅度地降低企业的生产使用成本；在本实施例中，所述储气包3的进口低于储气包3的出口，这样进入储气包3的气体会先上升至储气包3的出口，再从储气包3的出口排入与透气砖1的透气孔相连通的第一连接管道4，在氩气等气体在储气包3中上升的过程中，气体中的杂质会逐渐向下沉积在储气包3底部，从而确保无杂质的氩气等气体经透气砖1的透气孔进入钢包，有效避免了氩气等气体中的杂质进入钢水而污染钢水，大大提高了钢水的纯净度；在本实施例中，在钢壳2的底部围设有一圈钢包保护圈8，储气包3安装在钢包保护圈8内的钢壳2上，这样可以有效避免储气包3在搬运等过程因碰撞而损坏，进一步延长了钢包的使用寿命； As shown in Figure 1, the described anti-seepage plugging smelting ladle comprises: a steel shell 2 with a ventilating brick 1 arranged at the bottom, a gas storage bag 3 is arranged on the steel shell 2, and the ventilating brick 1 connects with the first connecting pipe 4 through the steel shell 2 The outlet of the gas storage bag 3 is connected, and the inlet of the gas storage bag 3 is connected with the quick-change joint 6 of the bottom blowing pipe through the second connecting pipe 5, and a one-way stop valve 7 is arranged on the second connecting pipe 5. The stop valve 7 only allows gas to enter the gas storage bag 3 along the second connecting pipe 5, and the ratio range between the volume of the gas storage bag 3 and the volume of the steel shell 2 is 0.00007-0.00009. In this embodiment, the The ratio between the volume of the gas storage bag 3 and the volume of the steel shell 2 is 0.00008. The gas storage bag 3 of this volume can better prevent the molten steel in the steel shell from penetrating into the air holes of the air brick 1, and can maximize the Significantly reduce the cost of production and use of the enterprise; in this embodiment, the inlet of the gas storage bag 3 is lower than the outlet of the gas storage bag 3, so that the gas entering the gas storage bag 3 will first rise to the outlet of the gas storage bag 3 , and then discharged from the outlet of the gas storage bag 3 into the first connecting pipe 4 connected with the air hole of the gas permeable brick 1. During the process of rising gas such as argon in the gas storage bag 3, the impurities in the gas will gradually flow to the gas storage bag 3. It is deposited on the bottom of the gas storage bag 3, so as to ensure that the gas without impurities such as argon enters the ladle through the vent hole of the vent brick 1, effectively preventing the impurities in the gas such as argon from entering the molten steel and polluting the molten steel, and greatly improving the purity of the molten steel In this embodiment, a circle of ladle protection ring 8 is provided around the bottom of the steel shell 2, and the gas storage bag 3 is installed on the steel shell 2 in the ladle protection ring 8, which can effectively prevent the gas storage bag 3 from being transported. and other processes are damaged due to collisions, which further prolongs the service life of the ladle;
本实用新型的工作原理如下： The working principle of the utility model is as follows:
当需向钢包内的钢水吹氩气时，将底吹管快换接头6与氩气储气罐9上的底吹管道10相对接，此时，氩气储气罐9中的氩气会先沿着第二连接管道5进入储气包3，进入储气包3的氩气再上升至储气包3的出口，在氩气在储气包3中上升的过程中，氩气中的杂质会逐渐向下沉积在储气包3底部，而干净的氩气则从储气包3的出口排入第一连接管道4，再从透气砖1的透气孔排入钢壳2中的钢水，有效避免了氩气中的杂质进入钢水而污染钢水，提高了钢水的纯净度，在氩气通过透气砖1的透气孔吹入钢壳2中钢水的过程中，储气包3中会储满氩气，储存有氩气的储气包3中会存在气体压力；当不需要向钢壳2内的钢水吹氩气时，直接拔出氩气储气罐9上的底吹管道10，此时，由于氩气被单向截止阀7锁在储气包3中，有效防止储气包3中因气体流失而产生负压，并且在储气包3中所存储的氩气的气体压力作用下，进一步使钢水不会反渗入透气砖1的透气孔中；即使在拔出底吹管道10的瞬间，储气包3因底吹管快换接头处产生负压而流失一部分氩气气体，但储气包3中剩余氩气的气体压力也足以确保钢水不会反渗入透气砖1的透气孔中，进而使得透气砖的透气孔不会被钢水堵塞，从而延长了钢包的使用寿命，也大大降低了企业的生产使用成本。 When it is necessary to blow argon to the molten steel in the ladle, the bottom blowing pipe quick-change joint 6 is connected with the bottom blowing pipeline 10 on the argon gas storage tank 9, and at this moment, the argon in the argon gas storage tank 9 will be first Enter the gas storage bag 3 along the second connection pipe 5, and the argon gas entering the gas storage bag 3 rises to the outlet of the gas storage bag 3. During the rising process of the argon gas in the gas storage bag 3, the impurities in the argon gas It will gradually deposit downwards at the bottom of the gas storage bag 3, while the clean argon gas will be discharged from the outlet of the gas storage bag 3 into the first connecting pipe 4, and then discharged into the molten steel in the steel shell 2 from the air hole of the ventilation brick 1, It effectively prevents impurities in the argon gas from entering the molten steel and contaminating the molten steel, improving the purity of the molten steel. When the argon gas is blown into the molten steel in the steel shell 2 through the vent holes of the vent brick 1, the gas storage bag 3 will store Full of argon, there will be gas pressure in the gas storage bag 3 storing argon; when it is not necessary to blow argon to the molten steel in the steel shell 2, directly pull out the bottom blowing pipeline 10 on the argon gas storage tank 9, At this time, because the argon gas is locked in the gas storage bag 3 by the one-way stop valve 7, the negative pressure in the gas storage bag 3 due to the loss of gas is effectively prevented, and the gas pressure of the argon gas stored in the gas storage bag 3 acts Further, the molten steel will not infiltrate into the air holes of the air brick 1; even if the bottom blowing pipe 10 is pulled out, the gas storage bag 3 will lose part of the argon gas due to the negative pressure generated at the quick change joint of the bottom blowing pipe, but The gas pressure of the remaining argon in the gas storage bag 3 is also sufficient to ensure that the molten steel will not reversely infiltrate into the vent holes of the vent brick 1, so that the vent holes of the vent brick will not be blocked by molten steel, thus prolonging the service life of the ladle and greatly Reduce the production and use cost of the enterprise.
