Description

Technical Field

[0001] The utility model relates to the technical field of refractory materials, in particular to a drum screen for refractory material production. Background Art

[0002] Refractory materials are inorganic non-metallic materials with a refractoriness of not less than 1580°C. Refractoriness refers to the Celsius temperature at which a cone-shaped sample of a refractory material can resist high temperature without softening and melting under no load. Before using refractory materials for forging, the refractory materials need to be screened:

[0003] Most of the existing drum screens are of the mesh type. This type of drum screen has a simple structure and uses a reducer to directly drive the rotating rod, which is directly connected to the screen drum. Then, with the help of a hoist, the external refractory material is put into the mesh to complete the refractory material screening operation.

[0004] This type of traditional drum screen may have some minor problems during use, such as smoke and dust splashing, easily polluting the surrounding environment, and easily interfering with the driving mechanism to cause it to not operate normally. For this reason, we propose a drum screen for refractory material production. Utility Model Content

[0015] Furthermore, it also includes isolation plates, which are respectively arranged on the opposite inner side surfaces of the two rotating cylinders, and the two isolation plates are rotatably connected to the inner arc surface of a packaging cylinder to achieve the isolation function.
