Description
Technical field
This utility model patent relates to a kind of filter, is specifically related to a kind of gas motor type being arranged on sea water pump suction side
Sea water filter before backwashing pump.
Background technology
Before the pump installed on boats and ships at present, sea water filter typically uses standard CB/T497 or CBM1061, and filter is arranged on sea
Water pump suction side, for intercepting the impurity of larger particles in sea water.But at the input of sea water pump, the position that filter is installed is empty
Between the narrowest and small, the surrounding of filter is surrounded by pipeline or valve member, safeguards that space is little, and part filter is often flooded by hydrops, and
Before pump, itself is without backwashing function, for filter cleaning can only manually Manual-cleaning, this keeps in repair to filter, maintenance work
Bring very big inconvenience.
Proposing a kind of automatic backwashing filter for this, utilize inside and outside differential pressure to be discharged by impurity, its principle is that sea water is situated between
Matter is by the filter screen in filter, and when, after filter net jam, above filter, differential manometer provides signal, filter rotates row by reducing motor
Dirty pipe, utilizes filter inside and outside differential pressure to recoil filter screen, removes the impurity above filter screen, reaches self-purging effect.
Concrete filter work process is: sea water filter import inflow filter to be filtered, flows to filter after filter element filtering
Device exports, and impurity is then gathered in filter element inner surface；Filter back flushing process: just form pressure when impurity gathers the inner surface at filter element
Difference, filter is fitted with differential pressure transmitter device, and when reaching backwash value, the incoming electrodynamic valve of signal, electrodynamic valve is opened, due to liquid
Pressure is more than atmospheric pressure, and facility uses filter inside and outside differential pressure, and certain media is then reverse flowed to inside filter screen outside filter screen, leads to simultaneously
Crossing reducing motor and axle is rotated and impurity is struck off by scraping blade, thus reach the cleaning action to filter element, backwashing water is through row
Dirty mouth flows to air.
After current full-automatic back washing filter is mainly used in pump, inside and outside differential pressure is utilized to be discharged by impurity, but uncomfortable
Before pump, because before pump being negative pressure, it is impossible to before forming pressure reduction, and pump, filter is installed, safeguarded that space is the least, installs, safeguards
Motor has great difficulty.
