The stripping attachment includes a crank, and the crank is stepped cylindrical structural, its miner diameter end with it is described spacing
Groove is used cooperatively.
Preferably：Fixing nut includes two kinds of specifications, the fixing nuts of described two specifications respectively with main tie
It is used cooperatively with subtie.
Preferably：The miner diameter end of stopper slot and crank is the circular configuration to cooperate；Or stopper slot and shake
Miner diameter end for cooperate polygonized structure.
Preferably：The depth of stopper slot is the 1/2 of fixing nut radius.
Preferably：The external diameter of circle is more than RO film barrel diameters where the supporting leg outward flange of star shaped supporting.
Preferably：When in use, it is star shaped supporting is smooth in RO film cylinders one end, respectively by main tie and secondary drawing
Then bar inserts the end of main tie and subtie corresponding on RO film end caps through the centre bore on star shaped supporting and lateral opening
In screw hole and tighten, each self-corresponding fixing nut is screwed on pull bar and tightened, is finally uniformly shaken successively with crank
Fixing nut, RO film end caps are smoothly pulled out by the fastening force of fixing nut and pull bar.
Compared with prior art, this stripping attachment disclosed in the utility model, it is mainly used in flourish extra large reverse osmosis (RO) film
The dismounting of end cap, it is a kind of multiple spot stress " manual thruster ", will using a plurality of bolt of long stem and the fastening force of nut screw thread
RO film end caps equably pull out from cylinder, and multiple spot uniform force, pulling force are big, safe and reliable, dismounting is quick, easy to use, system
It is low to make cost, removal efficiency is high.
