长江航运局青山船厂铸造车间冲天炉所用的修炉材料,原来是在一台小型轮辗机中配制而成的,在混辗时要三个人用铁铲翻转,不仅劳动强度大,而且常常将铁铲压在辗轮下,生产很不安全。为了解决这一问题,该厂在去年参照螺旋搅拌、螺旋输送的原理,制造了一台双螺旋修炉材料搅拌机,其结构如图1、图2所示。
Changjiang Shipping Bureau Castle Peak shipyard casting workshop cupola repair materials used in the furnace, turned out to be in a small wheel rolling machine in the preparation of the three people in the mixed rolling shovel, not only labor-intensive, and often will Iron shovel under the wheel, the production is not safe. In order to solve this problem, the factory made a double helix repair material mixer with reference to the principle of spiral mixing and screw conveyor last year. Its structure is shown in Fig. 1 and Fig. 2.
