Description
技术领域
[0001] 本发明属于过滤机技术领域，特别涉及一种针对陶瓷过滤机循环利用清洗液的清洗方法及装置。
背景技术
[0002] 陶瓷过滤机是采用微孔陶瓷板作为过滤介质，应用微孔透水不透气的毛细效应原理而设计的固液分离设备，具有高效、节能、滤液清澈及水资源充分利用、自动化程度高等特点。随着自然资源日渐紧缺，精矿研磨愈加细化，陶瓷过滤板微孔堵塞问题愈发突出，成为制约陶瓷过滤机产能的主要因素之一。
[0003] 因此，解决陶瓷板堵塞、恢复其再生能力成为提高陶瓷过滤机产能的重要途径。化学和物理混合清洗法是目前常用的方法，化学清洗是针对不同的过滤物料选择合适的清洗齐U，化学清洗剂与堵塞在陶瓷板内的细颗粒进行化学反应，达到细化颗粒的目的，再结合循环反冲洗，将细颗粒冲出。常用的化学清洗主要有简单酸洗、氧化酸洗、草酸清洗以及碱液清洗等等，不论是那种化学清洗都会都涉及到化学药剂和清洗水用量、清洗废液治理与排放等问题。
[0004] 而且目前，操作方法法是通过配药装置将清洗液送到陶瓷板内部，配合反洗水进行清洗；清洗过程中，槽内的清洗液通过料浆溢流管流入料浆池内，稀释料浆；清洗结束后直接将槽内的清洗液排入料浆池或者直接排掉。这样，就造成了化学药剂和水资源的浪费，以及环境的污染；同时，溢流和排放到料浆池内的清洗液会稀释甚至污染物料，影响设备产倉泛。
发明内容
[0005] 本发明的目的是提供一种新的清洗方法和装置，实现陶瓷过滤机清洗液循环利用，减少化学药剂和清洗水用量，降低生产成本和污液治理费用；避免清洗液排入料浆时污染料浆，降低物料浓度，进而影响过滤机产能；减少废液排放，降低环境污染程度。
[0006] 本发明的目的通过如下技术方案实现:
[0007] 清洗方法，在初次清洗时包括以下步骤:
[0008] a)将槽体内包括陶瓷过滤板在内的部件用清水冲洗干净，冲洗后的污水通过槽体底部的排料阀排放掉；
[0009] b)再加入清水至浸没槽体内的陶瓷过滤板，使用超声波对陶瓷过滤板进行物理清洗；
[0010] c)然后对陶瓷过滤板使用化学药水进行化学反冲洗，化学反冲洗期间使溢流出来的清洗液流至洗液池内，化学反冲洗完成后将槽体内的留存的清洗液排放到洗液池内；
[0011] d)最后使用净水对陶瓷过滤板进行反冲洗，反冲洗期间使溢流出来的清洗液流至洗液池内，反冲洗完成后将槽体内的留存的清洗液排放到洗液池内；
[0012]自第二次洗涤开始，以洗液池内的清洗液代替上述a)和b)步骤中的清水。
[0013] 实现前述方法的装置，包括其内部装有陶瓷过滤板2和超声波振子盒3的槽体1、可向槽体1注入液体的清水管路4和洗液水管路5、从槽体1内排除物料的排液管路17和带有排料阀20的排料管路、与陶瓷过滤板2内部连接的配药装置6和反洗系统7、洗液池13，其特征在于所述的洗液水管路5的一端通过循环泵12与洗液池13相连，另一端开口于槽体1的上方；所述的排液管路17的一端与洗液池13相连，另一端分别通过底流阀19和溢流阀18与槽体1的底部和顶部相连。
[0014] 进一步地，所述的配药装置6包括用来储存清洗药剂的储罐15和将药剂送到陶瓷过滤板2内部的计量泵16 ;所述的反洗系统7包括为净水送入陶瓷过滤板2内部提供压力的反洗泵11、控制反洗水通断的反洗阀10，使进入陶瓷过滤板2内部的水为净水的过滤器9 ;配药装置6和反洗系统7的出口汇并成反洗管路21后再与陶瓷过滤板2内部连接。
[0015] 更进一步地，所述的洗液池13的底部连接有排污阀14。
[0016] 再进一步地，所述的反洗系统7还包括一个用来显示进入陶瓷过过滤板2内的反洗水压力的压力表8。
[0017] 本发明与已有技术相比具有如下积极效果:可减少60%以上的清洗水用量，延长陶瓷板使用寿命，增加过滤机产能；减少化学药剂用量，降低生产成本；污液排放量小、节能环保。

具体实施方式
[0020] 下面结合附图对本发明作进一步详细说明，并给出如下实施例。
[0021] 由包括配药装置6、反洗系统7以及由洗液池13、循环泵12、洗液水管路5组成的洗液循环利用系统。
[0022] 陶瓷过滤机初次清洗:待过滤机停车后，将槽体1、陶瓷板2上的物料冲洗干净，经排料阀排放掉；通过清洗水管路4加入清洗水至浸没槽体1内的陶瓷过滤板2，启动超声波振子盒3进行超声波清洗；开启反洗泵11，将清洁水经反洗阀10、过滤器9送入陶瓷板内部自内向外反洗，同时，计量泵16将储罐15内的浓缩化学清洗剂送入反洗管路对陶瓷板2进行化学清洗。
[0023] 清洗一段时间后，槽体1内的洗液逐渐增多，打开洗液溢流阀18，溢出的洗液流入洗液池13内；清洗结束后，槽体1内的洗液经洗液底流阀19排放到洗液池13内。
[0024]自第二次清洗时:用循环泵12直接将洗液池13内的洗液送入到槽体1内，替代初次清洗时清洗水管路4内的清洗水；清洗结束后，洗液排放到洗液池13内，实现洗液循环利用。
[0025] 陶瓷过滤机运行一定周期后，通过排污阀14将洗液池13底部的泥渣排放掉。
