The utility model discloses an automatic backwashing filter core. The utility model comprises an upper cover, a middle cover, a lower cover, a skeleton, a filter element, a pull rod assembly and a spring; the upper cover and the lower cover are connected by a pull rod assembly, and the lower cover is provided with a spring, the middle cover is connected by a spring and the lower cover, and the skeleton is symmetrically arranged between the middle cover and the upper cover, and the skeleton and the pull rod assembly are filled with a filter element. The top of the filter element is placed between the upper cover and the middle cover, and there is a gap between the filter element and the pull rod assembly. A conveying channel is formed between the skeleton and the skeleton. An outlet is arranged on the top of the upper cover, and the conveying channel is connected with the outlet. The gap between the filter elements is changed by the compression and expansion of the spring. The utility model adopts plastic material, the service life can reach 10 years, and the cost is reduced. The clearance of filter element can be adjusted, and the greater the clearance, the better the blow back rate. Therefore, frequent backwashing is not needed to reduce the sewage produced during cleaning. The filter element is plum-blossom structure with large filtering area.

一种自动反冲洗过滤器滤芯
:本技术属于过滤器
,特别涉及一种自动反冲洗过滤器滤芯。
技术介绍
:在船舶压载水系统、船舶发动机冷却水、烟气脱硫废水处理等行业,大量海水或者灰水需要过滤。受海洋环境保护法的实施的影响,新船和维修期间均需安装海水过滤器;而在大气治理行业,脱硫工艺会采生大量的灰水。无论是陆地还是海洋选择一款合适的过滤分离滤芯对液体的合格排放起是至关重要的。现有的烧结网滤芯因间隙固定无法调整,清洗时会产生大量污水,存在清洗不干净的问题,需要频繁清洗,造成过滤效率低下,增加企业运行成本。此外烧结网滤芯易被污水中的杂质破坏,用于灰水处理时使用寿命不超过1年。公开于该
