Description
Technical field
Patent of the present invention is related to a kind of filter, and in particular to a kind of centrifugal backwash mounted on sea water pump suction side
Sea water filter before pump.
Background technology
For sea water filter generally using standard CB/T497 or CBM1061, filter is mounted on sea before the pump installed on ship at present
Water pump suction side, for intercepting the impurity of larger particles in seawater.However in the input terminal of sea water pump, the position sky of filter installation
Between it is very narrow, surrounded around filter by pipeline or valve member, safeguard that space is small, part filter is often flooded by ponding, and
Itself can only manually clean the cleaning of filter, this is repaired to filter, maintenance work without backwashing function before pump
Bring very big inconvenience.
A kind of automatic backwashing filter is proposed thus, is discharged impurity using inside and outside differential pressure, and principle is situated between for seawater
Matter is by the strainer in filter, and after filter net jam, differential manometer provides signal above filter, and filter is rotated by decelerating motor and arranged
Dirt pipe, recoils to strainer using filter inside and outside differential pressure, removes the impurity above strainer, reaches self-purging effect.
Specifically the filter course of work is：Sea water filter import to be filtered flows into filter, and filter is flowed to after filter element filtering
Device exports, and impurity is then gathered in filter core inner surface；Filter back flushing process：Pressure is just formed when impurity gathers the inner surface in filter core
Difference, filter are fitted with differential pressure transmitter device, and when reaching backwash value, signal is passed to motor-driven valve, and motor-driven valve is opened, due to liquid
Pressure is more than atmospheric pressure, and just using filter inside and outside differential pressure, certain media is then reverse flowed on the inside of strainer on the outside of strainer, is led to simultaneously
Crossing decelerating motor drives rotary shaft and scraping blade to impurity to strike off, and so as to reach the cleaning action to filter core, backwashing water is through row
Dirty mouth flows to air.
After current full-automatic back washing filter is mainly used in pump, impurity is discharged using inside and outside differential pressure, but uncomfortable
Before pump, because being negative pressure before pump, pressure difference can not be formed, and filter is installed, safeguards space very little before pumping, installation is safeguarded
Motor has great difficulty.
