Through as above technical scheme, pressure ring and filter core are just fixedly secured on the filter fixed head by fixture, can be because of the influence of current or the vibrations of device, and phenomenon loosening or that walk takes place, realize triangular excellent sealing.
More particularly, said fixture is a bolt.Said bolt is a preferred version for " T " shape bolt, and installation and removal are more convenient like this.
Said filter element filtering plate is the dividing plate of netted or hollow out, and said filter element filtering plate covers the opening of said filter core upper surface.So both can the slowly-releasing current to the impact of filter core, can guarantee the effect of filtering again.
Said pressure ring be concentric cylindrical with in round-formed annular solid, the opening of said filter core upper surface round-formed hole in said.
Outer cover at said filter core is provided with filter bag, and the port of said filter bag is not sealed; On the inwall of the circular hole of filter fixed head, offer draw-in groove, the port of said filter bag is fastened in the draw-in groove.In order to protect filter core better, stop filtrate and reveal, the second protection secondary filter is provided simultaneously, be provided with filter bag in the outer cover of said filter core.Said filter bag is the superfine fibre filter bag that an end does not seal, and can wrap up stainless steel coil in filter pocket mouths in the actual production, is more convenient for being fastened in the draw-in groove.
The outer cover of said filter bag is provided with filter basket; Said filter basket is the hollow out cylindrical shell that hollow and port are not sealed; The port of said filter basket is fastened in the said draw-in groove, also is provided with sealing ring between the port of said filter basket and the draw-in groove.The setting of filter basket can be protected filter core and filter bag on the one hand better, can add the effect of strong filter and sealing on the other hand.
Compared with prior art, the utlity model has following advantage and beneficial effect:
1, the hermetically-sealed construction of bag filter adopts fixture that filter core and filter bag are fixed on the mode on the filter fixed head in the utility model water treatment dechlorination device; Make device in use pressure ring be not easy to produce the phenomenon of loosening or landing because of the vibrations of the influence of current or device, effectively reach and form the purpose that machinery effectively seals between filter core and filter bag and the filtration fixed head.
2, the utility model adopts the mode of bolt to seal, and this mode is safe and efficient, and is convenient to very much installation and removal.
