Description

Graphite furnace hole plugging device for industrial silicon smelting Technical Field The utility model relates to the technical field of industrial silicon production, in particular to a graphite furnace hole plugging device for industrial silicon smelting. Background In industrial silicon production, the tapping (submerged arc) silicon water temperature typically exceeds 1550 ℃. After the silicon water is connected into the silicon bag, the furnace hole needs to be plugged in time to prevent the silicon water from flowing outwards. At present, when the furnace hole is plugged, most domestic manufacturers adopt pig iron plugs to push the plugged mud balls for plugging, and some manufacturers adopt wood plugs to push the plugged mud balls for plugging. However, the iron plugs are easy to be melted at high temperature and consume much, and can bring impurity iron into silicon water, the wooden plugs are not resistant to high temperature, and the wooden sticks are easy to burst and consume much when the moisture content of the wooden sticks is high. Namely, the existing iron plugs and wood plugs have the problems of high consumption and easiness in bringing impurity iron into silicon water. Disclosure of utility model Aiming at the situation, the utility model provides a graphite hearth plugging device for industrial silicon smelting, which aims to solve the technical problems that the existing iron plugs and wooden plugs are large in consumption and easy to bring impurity iron into silicon water. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a graphite hearth plugging device for smelting industrial silicon, which comprises: The ball pushing body is used for pushing the mud ball for blocking the furnace hole, and is internally provided with an accommodating groove and an avoidance hole which are communicated with each other, the accommodating groove and the avoidance hole penetrate the ball pushing body along the length direction, the diameter of the accommodating groove is larger than that of the avoidance hole, and a shoulder is formed at the joint of the accommodating groove and the avoidance hole; the shoulder is used for limiting the length of one end of the connecting piece exposed from the ball pushing body; The ball pushing body and the waste electrode after being used by the furnace opening are the same in shape and material, and are both cylindrical and graphite. In some embodiments of the utility model, the length of the push body is 120mm.
