Description

A kind of backwash filter core

Technical field

The utility model relates to a kind of filter core, especially a kind of backwash filter core.

Background technology

At present, the filter core of prior art is disposable element, and filter core is with after a period of time, because dirty obstruction filter opening causes filter core to scrap.The filter core filter opening stops up general just cartridge surface and is infected with dirt, is at most that dirt creeps in surperficial very shallow filter opening.Common filter core stops up the back and is difficult to clean, and one comes the dirt in the filter opening can't clean at all, even if having only surface contaminants, common filter core also can allow dirt enter in the filter opening in cleaning process.Is it that can not removed the reverse use of filter core with dirt because the absorption dirt produces that filter core stops up? answer is sure.But common filter core oppositely use can cause filtering bodies to damage.How just can address this problem? through test of many times, skeleton outside the filtering bodies outer wrapping of common filter core can be good at solving the problem of filter core back flush, recycling.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of can back flush, the backwash filter core of recycling.

The technical scheme in the invention for solving the technical problem is:

A kind of backwash filter core, by at the bottom of filtering bodies, the filter core, filter core lid, filter core inner frame, filter core seal cover and sealing ring form, in the filtering bodies outer wrap skeleton outside the filter core is arranged, the outer skeleton of filter core be embedded at the bottom of the filter core and the filter core lid between, the outer peripheral face of the outer skeleton of filter core at the bottom of by filter core underwall and the lid group parcel of filter core lid.

Compared with prior art, the utility model can back flush, recycling, reduces equipment operating cost, economizes on resources.
