Lid is connected between the small cover and big capping by threaded rod, and the threaded rod bottom is equipped with nut, the big closure base portion
Handle is equipped on the outside of big filter cylinder.
Preferably, folded filter cloth is equipped between the small filter cylinder and big filter cylinder, the folded filter cloth is located at the small filter cylinder
Outside and big filter cylinder inside, the folded filter cloth is that Nomex is made and material is added poly- four on the basis of polyester fiber
Vinyl fluoride, the folded filter cloth surfaces externally and internally cover special polyester webs.
Preferably, hollow thread hole, the small cover bottom and screw thread are equipped with threaded rod junction in the big capping
Bar junction is equipped with solid threaded hole, and the threaded rod is M12 type threaded rods, and the nut is M12 type nuts.
Preferably, the junction of the big filter cylinder in special flange bottom is equipped with card slot, the big filter cylinder and special flange it
Between to be detachably connected, the small filter cylinder is installed on the inside of special flange.
Preferably, the handle is made of stainless steel.
The advantageous effect that is reached of the present invention is：The present invention forms sealing, small filter in the small filter cylinder of special flange interior welds
Aperture area is not fixing seal for folded filter cloth to cylinder upper and lower side, and aperture area is that folded filter cloth is equal among small filter cylinder and big filter cylinder
Even distribution filter medium, small cover are mounted on small filter cylinder bottom, and big capping is mounted on big filter cylinder bottom, and big filter cylinder is in folded filter cloth
It is packed by bottom after installation is complete, top is stuck in after the card slot of special flange bottom and passes through big capping by the screw rod on small cover
Big filter cylinder is fixed with nut, structure of the invention is compact, long lifespan, and reinforcing support by inside with folded form filter cloth ensures really
Effective filtration area is compared with the filter core of existing same form-factor, and filter table area is much larger than existing filter core, to prolong significantly
The long equipment replacement filter core period reduces production cost, and can reduce existing equipment size under identical working condition, subtracts
Light investment of production, while ensureing that filter core will not deform external drum in the case where medium washes away, it is more suitable for the filtering of impurity in hydrogen peroxide.
