Description

一种海水过滤清污装置及其应用 技术领域
本发明涉及过滤设备技术领域，具体涉及一种海水过滤清污装置及其应用。
背景技术
现有技术中，自清式滤器通过滤芯过滤后产生的杂物或垃圾沉淀在滤器壳体内，清理时需要维修人员将滤芯取出，徒手或借用工具将杂物、垃圾等掏出，对于附着在壳体内壁的水草、海生物等则需要借用工具刮除。
现有的技术存在以下缺陷：
(一)、清理工序复杂且不易清理干净：现有自清滤器清理时，需要将顶部电机及滤芯拆卸下来，因杂物都存在壳体筒体内，而壳体笨重，且已固定在其安装座上，故维护人员需徒手或使用工具将杂物、垃圾、附着在壳体内的水草等掏出或刮除；
(二)、海水滤器长时间使用时，水草等海生物将附着在壳体底部及筒体壁上，清理困难，费时费力；
(三)、海生物附着在壳体里面，在壳体内成长繁殖，对壳体保护层进行侵蚀，加快了壳体的腐蚀，进而减小了滤器的使用寿命。
因此，亟需设计一种方便清污的海水过滤清污装置。
发明内容
本发明的目的在于提供一种方便清污的海水过滤清污装置。
为达此目的，本发明采用以下技术方案：
一方面，提供一种海水过滤清污装置，包括：

作为海水过滤清污装置的优选方案，所述网孔的尺寸大于所述滤芯的滤孔的尺寸。
作为海水过滤清污装置的优选方案，所述盖板上可拆卸安装有电机，所述电机的输出轴穿过所述盖板与所述滤芯的轴心处连接，所述电机可驱动所述滤芯绕所述输出轴的轴线转动。
作为海水过滤清污装置的优选方案，所述筒体的侧壁上沿其周向均设有若干卡孔。
作为海水过滤清污装置的优选方案，所述筒体的上端开口，所述筒体内设置有用于安装所述滤芯的固定支架，所述固定支架的高度不小于所述筒体的高 度。

下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。
在本发明的描述中，需要理解的是，术语“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，除非另有明确的规定和限定，术语“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个部件内部的连通或两个部件的相互作用关系。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。

如图1至3所示，本发明的实施例提供一种海水过滤清污装置，包括：壳体1，所述壳体1的侧壁上设置有进水口11和出水口12，所述壳体1的顶部开设有安装孔以及用于选择性封堵所述安装孔的盖板13；滤芯2和清污装置3，安装于所述壳体1内，所述滤芯2位于所述清污装置3的上方，所述清污装置3包括筒体31，所述筒体31的底板和/或侧壁上开设有若干网孔32；所述安装孔的尺寸不小于所述滤芯2和所述清污装置3的尺寸。本实施例对现有的海水滤器进行改进，在滤芯2的下方设置清污装置3，海水由进水口11进入壳体1内，经滤芯2过滤后由出水口12流出，过滤的海藻等污物直接落入至清污装置3上， 将盖板13打开，将滤芯2和清污装置3依次取出，然后将清污装置3内的污物倒掉即可；网孔32的设置可以使清污装置3取出时筒体31内的水及时流出，降低清污装置3取出时的重力。现有技术中，污物直接落入壳体1的底部，需要徒手或者借助工具将壳体1底部的污物清除，且难以清除干净，附着于壳体1底部的污物会对壳体1内的保护层产生侵蚀，与现有技术相比，本发明的海水过滤清污装置更方便清除污物，无需对壳体内部进行清理，且污物清除彻底，可防止壳体被海生物侵蚀。
优选地，本实施例中的筒体31的侧壁和底板上均设置有网孔32，可以更加方便、快捷地取出清污装置3。
优选地，所述壳体1内具有用于安装所述筒体31的安装槽14，所述筒体31的侧壁与所述安装槽14的侧壁间隙配合，以方便清污装置3的安装与取出，所述筒体31的直径大于所述滤芯2的直径，可以使经滤芯2过滤的污物直接全部被筒体31截留。
优选地，筒体31的底板靠近所述安装槽14的槽底的一侧设置有支撑脚33，通过设置支撑脚33，可用于支撑筒体31和滤芯2，以及用于过滤部分水。具体地，支撑脚33呈环形设置。
筒体31的上端开口，从而使污物可以直接落入筒体31内，筒体31内设置有用于安装滤芯2的固定支架4，固定支架4的高度不大于筒体31的高度，固定支架4的上端为圆形结构，其直径等于所述滤芯2的直径。优选地，固定支架4的高度等于筒体31的高度。现有技术中，固定支架4的高度等于滤芯2的高度，本实施例将固定支架4的高度缩短至与筒体31等高，或者小于筒体31的高度，在有效截留污物的基础上可以使滤芯2稳定安装于固定支架4上。
其中，固定支架4包括支柱和顶板，支柱一端与清污装置3的底板连接， 另一端与该顶板连接。
本实施例中，固定支架4可以直接放置在筒体31的底板上，也可以与筒体31的底板焊接。滤芯2可以通过螺栓与固定支架4的顶板可拆卸连接，也可以通过电磁吸组件固定支架4连接。采用电磁吸组件连接时，所述滤芯2的底板采用铁质材料制成，或者该底板的下端面镀铁，或者该底板上设置有磁性材料，对应地，固定支架4的顶板上固定有电磁铁，电磁铁与控制器连接，控制器可控制电磁铁与滤芯2的底板选择性吸附。当海水过滤清污装置用于过滤时，控制器控制电磁铁与滤芯2的底板磁吸，从而将滤芯2固定在固定支架4上；当需要清污时，将盖板13打开，控制器控制电磁铁解除与滤芯2底板的磁吸作用力，可以直接将滤芯2和清污装置3单独取出。
本实施例中，所述筒体31的底板靠近所述安装槽14的槽底的一侧设置有加强筋34，加强筋34呈环形设置，沿竖直方向，所述加强筋34的长度小于所述支撑脚33的长度，由于筒体31的底部为网状结构，加强筋34的设置可以提高筒体31的底板的受力强度，使筒体31的底板不易变形。
所述网孔32的尺寸大于所述滤芯2的滤孔的尺寸，可以使筒体31内的污物中的水更加快速地流出。
所述盖板13上可拆卸安装有电机5，所述电机5的输出轴穿过所述盖板13与所述滤芯2的轴心处连接，所述电机5可驱动所述滤芯2绕所述输出轴的轴线转动，电机5可拆卸安装于盖板13上，方便打开盖板13取出滤芯2和清污装置3。
所述筒体31的侧壁上沿其周向均设有若干卡孔35，具体地，筒体31的侧壁上沿其周向均设有四个卡孔35，即相邻两个卡孔35之间的夹角为90°，采用工具插入该卡孔35中勾住筒体31，即可将清污装置3取出。
为了更加方便地取出滤芯2和清污装置3，本实施例在上述实施例的基础上进行了优化。具体地，安装槽14的槽底设置有升降装置，升降装置的上端与清污装置3的底板连接，清污装置3的下端与升降装置连接，升降装置通过驱动装置与控制器连接，通过控制器可以控制驱动装置驱动升降装置升降，从而带动清污装置3上升或者下降。
优选地，筒体31的外壁间隔凸设有若干凸部，凸部上开设有导孔，导孔的轴向沿竖直方向延伸，所述安装槽14的槽底对应所述导孔的位置设置有导向杆，所述导向杆远离所述槽底的一端延伸至邻近所述盖板13，导向杆与导孔插接配合，且所述导孔可沿所述导向杆的长度方向上下滑动，升降装置带动清污装置3升降时，导向杆与导孔的配合可以提高清污装置3升降时的稳定性，避免清污装置3升降过程中发生偏移而无法取出。
其中，所述升降装置为液压千斤顶或者油缸等。
所述安装槽14的侧壁上且邻近所述安装槽14的槽底设置有排水口15。海水过滤之后，将该排水口15的阀门打开，先将安装槽14内的海水排出，再将清污装置3取出。
