发明实施例
本发明的实施方式
[0014] 为了使本实用新型的目的、 技术方案更加清楚, 以下结合附图及实施例, 对本 实用新型进行进一步说明:
[0015] 如图 1〜图 5所示的一种精确计量装置, 包括壳体 1和转子 2; 所述壳体 1中空形 成转筒 11, 壳体 1上方设有与转筒 11相通的进料口 12, 壳体 1下方设有与转筒 11 相通的出料口 13 ; 转子 2安装于转筒 11中, 转子 2与转筒 11形成密闭配合, 以防 止流体外漏; 转子 2连接电机 (图中未示出) , 由电机驱动在转筒 11中转动。
[0016] 转子 2外壁对应进料口 12和出料口 13形成三圈计量槽 21、 22、 23 ; 所述计量槽 2 1和 22之间、 22和 23之间分别设有纵隔板 241, 242; 每一圈计量槽 21、 22、 23的相 邻计量槽之间分别设有横隔板 211, 221, 231 ; 且所述计量槽 21、 22、 23的横隔板 2 11, 221, 231在径向上相互错位, 使得三圈计量槽 21、 22、 23分别与进料口 12和出 料口 13对齐; 所述三圈计量槽分别与进料口 12对齐使得轮子 2的剪切位错开, 有 效减小了转子 2剪切力。
[0017] 所述进料口 12的上端呈上窄下宽的梯形, 梯形的左边与转子 2的横隔板 211和横 隔板 221的左侧形成锐角开口, 梯形的右边与转子 2的横隔板 231和横隔板 221的 右侧形成锐角开口; 这样使得进料口 12使得转子 2转动时, 横隔板 211, 221, 231与 进料口 12相遇时为单点接触, 避免了一条线接触, 这也大大减小了转子 2的剪切 力。
[0018] 上述两处设计有效的减小了转子 2的剪切力, 这使得物料可以连续的从进料口 1 2进入, 为后续计量装置的精确计量提供了先决条件。
[0019] 出料口 13偏心设置于转筒的爬坡位, 使得计量槽 21、 22、 23在爬坡过程中出料 , 出料速度可根据转子 2的转动速度进行控制调节, 又由于横隔板 211, 221, 231在 径向上相互错位, 使得计量槽 21、 22、 23中的物料依次从出料口 13流出, 到达 精确计量的效果。
[0020] 所述出料口 13上的壳体 1侧壁对应计量槽 21、 22、 23的设有吹气孔 212、 222、 2 32, 用于将物料从计量槽吹落, 使物料从出料口 13落下, 避免物料累积沉淀于 计量槽内, 影响后续的精确计量。
[0021] 本实用新型的有益效果为: 喂料的同时无需抽气, 不会影响计量精度; 设有多 圈计量槽, 且多圈计量槽的横隔板径向错位, 使得多圈计量槽中的物料依次从 出料口流出, 达到精确计量的效果, 且也使得转子在进料口的剪切力减小; 另 外进口的上端呈上窄下宽的梯形的设计, 进一步减小了转子的剪切力, 使得物 料连续的且较均匀的落入进料口, 为计量装置后续的精确计量提供了先决条件 ; 吹气孔设计避免了物料累积沉淀于计量槽内, 影响后续的精确计量。
[0022] 以上所述, 仅是本实用新型较佳实施例而已, 并非对本实用新型的技术范围作 任何限制, 故凡是依据本实用新型的技术实质对以上实施例所作的任何细微修 改、 等同变化与修饰, 仍属于本实用新型的保护范围。
