Slag collecting filter section for casting and pouring

The utility model relates to the field of casting production of large castings, in particular to a slag collecting filter section for casting and pouring. Comprising a first sand core (1), a second sand core (2) and a ceramic filter (3), the first sand core (1) and the second sand core (2) are semi-snail pump shell sand cores; the first sand core (1) and the second sand core (2) which are in butt joint form a filter chamber, and the ceramic filter sheet (3) for casting is embedded at the joint of the first sand core (1) and the second sand core (2) which are in butt joint to form a complete slag collection filter section. The device not only has filtering and rectifying functions, but also has a two-layer slag collecting and purifying function, so that the production cost is reduced. 本实用新型涉及大型铸件的铸造生产领域，尤其涉及一种铸造浇注用集渣过滤器节。包括第一砂芯(1)、第二砂芯(2)与陶瓷过滤片(3)；所述第一砂芯(1)、第二砂芯(2)均为半蜗牛泵壳型砂芯；两个对接的第一砂芯(1)、第二砂芯(2)形成过滤室，在对接的第一砂芯(1)、第二砂芯(2)接口处嵌入铸造用陶瓷过滤片(3)，组成完整的集渣过滤器节。本实用新型不仅具有过滤、整流功能，而且具有二层次集渣净化功能，降低生产成本。
