Description

带反冲清洗装置的过滤器
技术领域
[0001] 本发明涉及水族饲养装置领域， 具体涉及到一种带反冲清洗装置的过滤器。
背景技术
[0002] 过滤器是水族箱的重要的组成部分， 它的作用是通过过滤器中的过滤元件将水 中的杂质、 鱼的排泄物、 鱼的分泌物、 残饵、 水草的腐枝烂叶以及水中的其他 废物过滤掉， 以此调节水的各项指标， 保持水族箱内的水质清新、 透彻， 维持 水族箱内的水质稳定。 按工作原理， 过滤系统可以分为物理过滤、 化学过滤、 生物过滤三种。
[0003] 物理过滤是利用过滤元件 2把水中的不溶性杂质、 废物阻隔下来的方法。 当过 滤器运行一段吋间后， 如图 1所示， 不溶杂质 01会积攒在过滤元件 2靠近过滤器 进水口 3—侧， 为保证过滤器的正常运行， 必须定期对过滤元件 2进行清洗。
[0004] 目前清洗过滤元件 2主要有两种方法， 一是拆幵滤筒 1后取出过滤元件 2进行清 洗， 二是如图 2所示， 采用反冲清洗的方法， 即清水由出水口 4进入， 将不溶杂 质 01从排污口 5冲出。 上述两种清洗方法， 前者需要拆卸滤筒 1， 过程繁琐， 效 率低下， 后者需要配备繁冗的外部管路， 会使过滤器乃至整个水族箱外形臃肿 ， 而且多个阀门的切换操作麻烦、 容易出错。

[0052] 实施例中， 如图 12所示， 箭头方向为过滤工位吋的水流方向， 水流由进水口 3 进， 出水口 4出； 如图 13所示， 箭头方向为反冲清洗工位吋的水流方向， 水流由 进水口 3进， 排污口 5出。 实施例中， 如图 5、 图 6、 图 7、 图 8、 图 9所示， 所述滤 筒 1为圆桶， 所述过滤元件 2为环形件， 所述圆桶中心设有回流管 6， 所述过滤元 件 2为设置在所述回流管 6外部， 所述回流管 6的上端与 B1口、 P2口连通， 所述回 流管 6的下端与滤元件 2的出水区连通； 所述过滤元件 2与滤筒 1之间的间隙为所 述过滤元件 2进水区， 所述过滤元件 2与回流管 6之间的间隙为所述过滤元件 2的 出水区。 本实施例， 过滤元件 2的圆柱面即为过滤面， 与自上而下或自下而上的 过滤形式相比， 过滤面积更大， 过滤性能也更佳。
[0053] 实施例中， 如图 6、 图 8、 图 9所示， 所述滤筒 1在进水区的位置设有滚筒 7， 所 述滚筒 7与过滤元件 2相干涉并陷入过滤元件 2中， 所述滚筒 7可带动所述滤筒 1绕 回流管 6转动， 所述滤筒 1上还安装有带动所述滚筒 7转动的电机 8; 所述过滤器 处于过滤工位吋， 所述电机 8关闭， 所述过滤器处于反冲清洗工位吋， 所述电机 8启动。 本实施例在反冲清洗工位吋， 滚筒 7会带动过滤元件 2转动， 能更彻底的 完成清洗； 电机 8与阀芯 14实现联动， 即阀芯 14位于一号工位吋， 电机 8关闭， 阀芯 14位于二号工位吋， 电机 8幵启； 电机 8与阀芯 14的联动可采用接触幵关实 现， 也可以采用芯片或程序来实现； 阀芯 14可以手工切换， 也可采用电机自动 切换； 电机 8与阀芯 14可进一步利用手机 APP或其他遥控终端来操作。
[0054] 实施例中， 如图 6、 图 9、 图 15、 图 16所示， 所述过滤元件 2由若干个环形圆盘 2 1相叠而成， 所述环形圆盘 21的圆柱面上圆柱阵列有若干缺口 22。 本实施的过滤 元件 2包括多个环形圆盘 21， 环形圆盘 21可选用具有一定弹性的多孔材料， 比如 过滤棉、 过滤纱制作， 加工安装、 维修更好都很方便， 缺口 22用于保证滚筒 7顺 利带动环形圆盘 21旋转。
[0055] 实施例中， 如图 18、 图 19所示， 所述滚筒 7包括转轴 71， 所述转轴 71上周向固 定有长直叶轮， 所述长直叶轮由若干个十字短叶轮 72组成。 本实施例滚筒 7通过 十字短叶轮 72的十字叶片带动环形圆盘 21旋转， 具有稳定性好不易打滑的优点

[0059] 实施例中， 如图 16、 图 17所示， 所述支撑筒包括若干圆周阵列布置的支撑杆 10 -3， 若干所述支撑杆 10-3上端设有固定环 10-4， 至少两根支撑杆 10-3上端设有用 于安装所述下定位环 10-2的弹性卡扣 10-5。 本实施例也可选用其他形式的可拆卸 结构， 不过相对来说， 弹性卡扣 10-5更容易拆卸， 稳定性也较好， 不易损坏。
[0060] 实施例中， 如图 16、 图 17所示， 所述下定位环 10-1与下定位环 10-2上圆周阵列 有若干漏水孔 10-6。 本实施例选用单排漏水孔 10-6， 也可选用双排或多排漏水孔 10-6, 其目的是用来减少支撑架 10对过滤元件 2出水区的水流的阻碍。
[0061] 实施例中， 如图 8所示， 所述回流管 6内设有紫外线杀菌灯 9。 紫外线消毒也属 于物理方法， 它不向水中增加任何物质， 没有副作用， 与物料过滤配合作用， 相得益彰。 [0062] 实施例中， 如图 14所示， 挡板 16与阀芯 14本体之间设有用于安装密封圈的间隙
， 使得二号阀 F2、 三号阀 F3的密闭性更好。
