以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是, 此处所描述的具体实施方式仅用于说明和解释本发明, 并不用于限制本发 明。
本发明提供了一种料斗, 该料斗包括料斗本体 1, 该料斗本体 1的内周 面包括工作面, 该料斗本体 1 由轻金属合金制成, 并且所述工作面上覆盖 有耐磨层。
针对现有技术中的料斗重量重、难以修复的缺点, 本发明的料斗本体 1 采用轻金属合金制成, 这样对于同样大小的料斗而言, 本发明的料斗的重 量远小于现有技术的采用钢材制成的料斗的重量, 所述轻金属合金可以是 铝合金、 镁合金或钛合金等本领域常见的并且刚度适合的轻金属合金。
由于料斗本体 1的内周面的工作面与该料斗所盛放物料(例如混凝土) 长期接触, 工作面长期受到所盛放物料的摩擦, 因此, 本发明的料斗在料 斗本体 1 的工作面上增设耐磨层, 以增强料斗的耐磨性, 并且料斗在耐磨 层磨损后可以修复耐磨层并继续使用, 这样也延长了料斗的使用寿命。 其 中, 所述工作面是指料斗中盛放最大体积的液体时, 液体所覆盖的料斗本
体 1的内周面。
并且, 优选地, 料斗本体 1 由轻金属合金一体形成。 这种一体形成的 料斗本体 1 中没有由于焊接而形成的死角, 因此可以减少积料现象, 并且 一体形成的料斗本体 1的强度也高于由板材焊接成的料斗本体 1的强度。
在选择形成料斗本体 1 的轻金属合金材料时, 从密度、 刚度和价格等 方面综合考虑, 优选铝合金, 铝合金不仅密度低、 耐腐蚀性好、 刚度符合 要求, 而且价格低、 取材方便。 并且, 耐磨层优选为氧化铝陶瓷层, 氧化 铝陶瓷硬度大、 密度小并且耐磨性极好, 可以大大延长耐磨层的使用寿命。
所述耐磨层可以采用本领域常规的方法制成, 例如可以在工作面上涂 覆耐磨材料, 例如将陶瓷粉末、 高分子材料以及其他辅助添加剂充分搅拌 混合均匀后使用搪涂装置或浇注机等将上述混合物涂抹于工作面上, 再经 烘烤等工序形成耐磨层, 更优选地, 耐磨层可以采用阳极氧化或微弧氧化 的方法形成, 这样形成的耐磨层为以基体(料斗本体 1 )金属氧化物为主的 陶瓷膜层, 这样形成耐磨层与料斗本体 1的结合性好、 厚度小且硬度大。
在这种情况下, 耐磨层的厚度优选为 0.1mm-0.3mm, 维氏硬度在 2000 以上。
本发明还提供了一种用于制作本发明的料斗的方法, 该制造方法包括: 步骤一: 采用轻金属合金材料制造料斗本体 1 ; 步骤二: 向所述料斗本体 1 内注入电解液 2, 并且使电解液 2覆盖料斗本体 1的工作面, 将料斗本体 1 与电源的阳极 3相连, 并将电解液 2与电源的阴极 4相连, 通电进行阳极 氧化或微弧氧化。
在该料斗的制造方法中,采用阳极氧化或微弧氧化的方式在料斗本体 1 上形成耐磨层, 并且, 步骤二如图 2所示, 即直接在料斗本体 1中注入电 解液进行阳极氧化或微弧氧化, 操作方便、 无需使用其它的容器盛放电解 液而且能够节省电解液用量。 具体地, 例如, 按照一般的阳极氧化或微弧 氧化的思路, 需要先对料斗本体 1 的非工作面进行绝缘处理, 然后将料斗
本体 1放入一个比料斗本体 1更大的容器中, 向该容器中注入电解液并使 电解液没过料斗本体 1 的工作面, 然后进行阳极氧化或微弧氧化, 与这种 方法相比, 本发明的料斗的制造方法不仅不需要所述容器、 不用对料斗本 体 1的非工作面进行绝缘处理还能大大减少电解液的用量。
其中, 所述步骤一包括采用轻金属合金材料整体铸造成型形成料斗本 体 1。 料斗本体 1采用整体铸造成型的方式形成可以避免焊接造成的死角, 减少积料现象, 同时提高料斗强度。
其中, 在进行阳极氧化或微弧氧化过程中, 料斗本体 1和电解液 2分 别与电源的连接形式可以是: 料斗本体 1通过第一导线 5与电源的阳极 3 相连, 电源的阴极 4与导电件 7通过第二导线 6相连, 并且导电件 7与电 解液 2接触但不与料斗本体 1接触, 其中, 如图 2所示, 导电件 7可以是 一块不锈钢块。
另外, 所述电解液 2可以采用本领域公知的电解液, 例如, 磷酸盐体 系或铝酸盐体系的电解液, 优选情况下, 电解液 2采用以硅酸盐为主成膜 剂的硅酸盐体系电解液, 采用硅酸盐体系电解液进行阳极氧化或微弧氧化 时, 氧化膜生长迅速, 制备出的氧化膜表面较光滑平整、 硬度大且耐磨性 好, 而且, 还可以在电解液 2 中添加添加剂以进一步改善所形成的耐磨层 的组织和性能。
并且, 优选地, 所述电源可以采用脉冲电源, 使用脉冲电流时氧化膜 生产速度快、 成膜致密均匀且所形成的氧化膜的抗腐蚀性好。
为了进一步提高耐磨层的性能并在较短时间内形成符合要求的耐 磨层, 可以进一步控制工艺条件, 例如, 当采用上述的以硅酸盐为主成 膜剂的硅酸盐体系电解液和脉冲电源时, 可以将工艺条件控制为: 电解液 2 的 PH值为 8-12, 电源的电压为 600V-800V, 阳极氧化或微弧氧化的处理时 间为 0.5h-1.0h。
此外, 当本发明的料斗的耐磨层磨穿失效后, 可以再采用本发明的料
斗的制造方法中的步骤二对料斗的耐磨层进行修复, 修复后的料斗又可重 新投入使用, 这样不仅降低了成本而且节能环保。
另外, 本发明还提供一种泵送系统, 该泵送系统的料斗为根据本发明 的料斗。 由于该料斗重量轻、 耐磨性好且易于修复, 因而不仅减轻了泵送 系统的承重负荷, 还减少了泵送系统的维护成本。
以上结合附图详细描述了本发明的优选实施方式, 但是, 本发明并不 限于上述实施方式中的具体细节, 在本发明的技术构思范围内, 可以对本 发明的技术方案进行多种简单变型, 这些简单变型均属于本发明的保护范 围。
另外需要说明的是, 在上述具体实施方式中所描述的各个具体技术特 征, 在不矛盾的情况下, 可以通过任何合适的方式进行组合。
此外, 本发明的各种不同的实施方式之间也可以进行任意组合, 只要 其不违背本发明的思想, 其同样应当视为本发明所公开的内容。
