Description

自动除渣刮板过滤器
所属技术领域
本发明涉及一种能够完成自动过滤除渣工序的一种自动除渣刮板过滤器。
背景技术
过滤器在造纸、化工、轻工、食品等行业中广泛应用。过滤器过滤机理是将污染物拦阻在过滤介质的表面,但由于滤网的纳污量小,而常受污染物堵塞,当被滤介质含有较多不规则形状杂质或粘稠杂质时,滤网被堵的速率会非常快,有时会2个月或更短时间就需清理滤网1次,因而影响到正常生产。目前,市场上出现的大部分过滤器没有自动除渣的功能。
但是需要这种人工除渣的过滤器,使得人工成本增加,进而使得加工成本高,企业的市场竞争力下降。
发明内容
为了克服过滤器需要人工除渣的弊端,本发明提供一种自动除渣刮板过滤器。
本发明解决其技术问题所采用的技术方案是:
该自动除渣刮板过滤器包括壳体,滤筒,刮板组件,减速电机,链轮,链条,支腿,其特征在于:被滤介质从顶部流下通过过滤器时,大于网孔尺寸的杂质则被滤网留住,在重力作用下杂质密度大于正常介质的应沉积在过滤器壳体底部,其中小颗粒的通过排净口排出,大颗粒的在停车时通过手孔拿出;减速电机通过链轮和链条带动刮板组件旋转,刮板组件将附着在滤筒上的较小的杂志除下来,完成过滤和自动除渣过程。
刮板结构包括刮刀,螺钉,底座,弹簧,压盖,螺母,横杆,其特征在于:弹簧的引入使刮刀的伸长量可调,以保证刮刀转动中与滤筒保持微量间隙,一方面避免接触产生摩擦噪音,另一方面防止堵塞网孔的大颗粒杂志受径向压力过大而压出网孔。
本发明的有益效果是,该自动除渣刮板过滤器完成自动过滤除渣工序,具有生产效率高、工人劳动强度小、结构紧凑、移动方便等特点。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1是本发明的总体结构示意图。
图2是刮板结构示意图。
图1中1.壳体,2.滤筒,3.刮板组件,4.减速电机,5.链轮,6.链条,7.支腿。
图2中8.刮刀,9.螺钉,10.底座,11.弹簧,12.压盖,13.螺母,14.横杆。
具体实施方式
在图1中,包括壳体,滤筒,刮板组件,减速电机,链轮,链条,支腿,其中被滤介质中的污染物材质多为硅铝钙等氧化物或者砂粒、有机纤维物或者系统自身运行中产生的污垢,形状是多种多样;当被滤介质从顶部流下通过过滤器时,大于网孔尺寸的杂质则被滤网留住,在重力作用下杂质密度大于正常介质的应沉积在过滤器壳体底部,其中小颗粒的通过排净口排出,大颗粒的在停车时通过手孔拿出;减速电机(4)通过链轮(5)和链条(6)带动刮板组件旋转,刮板组件(3)将附着在滤筒(2)上的较小的杂志除下来,完成过滤和自动除渣过程。
在图2中,包括刮刀,螺钉,底座,弹簧,压盖,螺母,横杆,其中螺钉(9)将刮刀(8)与底座(10)链接起来,弹簧(11)的引入使刮刀的伸长量可调,以保证刮刀转动中与滤筒保持微量间隙,一方面避免接触产生摩擦噪音,另一方面防止堵塞网孔的大颗粒杂志受径向压力过大而压出网孔,以达到最佳过滤效果。

Claims (4)
