Description

全自动过滤浓缩一体化装置及其使用方法
技术领域
本发明涉及环保技术领域,具体涉及一种全自动过滤浓缩一体化装置及其使用方法。
背景技术
现有的料浆过滤一般采用板框式压滤机进行操作,板框式压滤机普遍存在不易清洗,易堵塞,过滤不高效,含固率低,分离效果不好,不容易卸料等缺点。尤其是对于沉降速度慢,难以沉降的料浆,效果更加不好。
另外,板框式压滤机普遍存在占用空间大,需要较多的人工,增加了企业的开支。
发明内容
为了解决上述技术问题中的不足,本发明的目的在于:提供一种全自动过滤浓缩一体化装置,能够快速的进行固液分离,迅速脱饼,并易于冲洗。
本发明为解决其技术问题所采用的技术方案为:
所述全自动过滤浓缩一体化装置,包括壳体,壳体的上端设置吊耳,壳体的外侧部分别设置检修口和控制箱,壳体的前部设置进料口,壳体的下部设置排渣口和支腿,壳体的内部设置浓缩腔,浓缩腔的内部设置滤清液管路和多组滤元,滤元与滤清液管路相连通,滤清液管路分为依次连通的上直管、竖管和下直管,上直管的端部设置进气口,下直管的端部设置出液口,所述滤元交替排列,并分别安装在上直管和下直管上,所述下直管上设置反冲洗进口。
进一步优选,滤元的表面设置螺旋棱,螺旋棱之间形成凹槽,滤元的外侧套装滤袋。
进一步优选,所述浓缩腔的一侧设置加药口,加药口与浓缩腔相连通,进料口也与浓缩腔相连通。
进一步优选,壳体的内部设置承托板,上直管和下直管安装固定在承托板上。
进一步优选,浓缩腔的下部设置电动闸板阀。
全自动过滤浓缩一体化装置的使用方法,包括以下步骤:
进料:由供料泵将料浆由进料口泵入,持续充满浓缩腔;
滤饼层形成:固体颗粒被滤元截留在表面形成滤渣,浓缩腔内的料浆连续增稠,过滤阻力加大,滤饼厚度逐渐增加,过滤时间越长,滤渣的颗粒度越大,分离效率也就越高;
滤清液排出:出液口接真空泵,保证滤清液管路为负压状态,滤清液不断穿过滤元并沿滤元内部凹槽,流经滤清液管路由出液口的排出;
脱饼:当因过滤过程的进行,滤渣一直在滤元表面及浓缩腔内,浓缩腔内压力达到一定值时,出液口关闭,底部排渣口打开,由进气口充入气体(空气、氮气或者蒸气,以满足不同含水率滤出物排放工况要求),使滤元膨胀,滤渣进一步压实,电动闸板阀开启,两滤元间的滤渣在气体吹脱及重力作用下迅速卸落至底部。充入的气体促进了排渣,同时带走滤饼中的水分,对滤渣进一步干燥,使滤饼中的水分降至更低。排渣口接螺杆泵;
排渣结束后,重新压紧滤元,开始下一工作循环;
洗涤:进气口、出液口关闭,清洗液由反冲洗进口泵入依次经滤清液管路、滤元、浓缩腔,清洗液根据物料化学性质进行选择。在反复冲洗下,滤袋表面及浓缩腔内残留滤渣得到清除,恢复过滤效果。洗涤后的混合液经排渣口流至前端等待在下一分离工作中进行处理。
与现有技术相比,本发明具有以下有益效果:
本发明结构新颖,结构设计灵活,具有含固率高,分离效果好,占地面积少,容易卸料等特点,可用于介质中存在大量细微颗粒、沉降速度缓慢、甚至难以沉降的料浆的分离操作;另外,本发明自动化程度较高,控制箱设有PLC系统,利用时控开关、压力传感器、流量传感器、变频器共同发挥作用,通过智能感应对电磁阀及其他配套设备实现联锁控制,以控制整个分离过程;使每次的固液分离更精准地分挥最大功效;且无需人工操作,料液不需要和人直接接触。
