Description
技术领域
本发明涉及铸造行业,具体涉及一种铸造用过滤网座及其制备方法。
背景技术
采用陶瓷过滤器应用于金属液过滤净化，是一种生产高质量洁净铸件铸件的常规工艺。陶瓷过滤器是三维网状结构，通常放置在横浇道上甚至内浇道上。为了避免金属液从陶瓷过滤器侧面流出，需要将陶瓷过滤器包裹在浇注系统内。根据检索，专利201630381525.4公开了一种陶瓷过滤网座，过滤网座一端为圆形，与浇道管匹配连接，另一端为凹面，与陶瓷过滤器相匹配，两块过滤网座对接后，能够将陶瓷过滤器包裹在内，实现了陶瓷过滤器包裹在浇注系统内，以净化金属液。但是这种陶瓷过滤网座存在煅烧过程复杂，属于高能耗、高污染，并且重量大，不易拼接；在使用后产生坚硬固体废弃物，不易除去，所造成的不可再生资源、能源及人工浪费相当大。
发明内容
为了解决上述陶瓷过滤网座存在复杂的煅烧过程、高能耗、高污染、重量大、不易拼接以及不易除去等不足,本发明提供了一种铸造用过滤网座，其制备工艺简单，生产和使用都是绿色环保，具有较好的弹性且操作方便。
为解决上述不足，本发明采用的技术方案为：
一种铸造用过滤网座，包括过滤器，所述过滤网座包括浇道接口、托架、网座和法兰边；所述浇道接口与托架相连接；所述托架与网座相连接；所述网座用于安装过滤器；所述网座与法兰边相连接；所述铸造用过滤网座由陶瓷纤维、碳纤维、纸纤维、木浆纤维、增强材料、高温粘结剂和助剂制成。
进一步的,所述过滤网座为一体成型。
进一步的，所述浇道接口用于匹配连接不同规格的浇注管道。
进一步的，所述网座用于匹配安装不同尺寸的过滤器。
进一步的，所述浇道接口的直径为25～90mm。
进一步的，所述托架的锥度为70～150度。
进一步的，所述网座的边长为80～160mm。
进一步的，所述法兰边的边长为3～10mm。
一种铸造用过滤网座的制备方法，包括以下步骤：
称量原料:按配比称量陶瓷纤维、碳纤维、纸纤维、木浆纤维、增强材料、高温粘结剂和助剂；
打浆:将纸纤维、陶瓷纤维、碳纤维和水按1:10～1:20配比进行打浆；打浆完成后将浆料、增强材料、高温粘结剂和助剂投入到配有搅拌装置的浆池中进行搅拌；
模塑成型:将浆料送入成型设备内，实现浆料在浆池与成型设备之间的循环；成型设备模塑成型过滤网座形状的粗胚；将粗胚进行干燥得到胚体；将粗胚进行热压整形得到半成品胚体；将半成品胚体切掉浇道接口和法兰边的毛边得到铸造用过滤网。
