On dirty filtration upper cover plate and lower end is fixed on greasy dirt and is filtered the pull bar molectron 56 of lower shoe 53, is positioned at greasy dirt mistake
Fuel feed hole 57 in the middle of filter upper cover plate.
Operation principle: when carrying out single contaminant filter, by the heavy water storage barrel 2 that is not connected with self priming pump 3
Stop valve on inlet tube mouth, two loop cutoff valves 11, filter inlet stop valve 13 and air relief valve 14 closes
Close, the filtering outlet stop valve 15 of greasy dirt filter 5 is closed, and opens self priming pump 3, and heavy water is by connecting
Heavy water storage barrel 2 enters device for filtering impurities 4 and filters, and the finished product after filtration is through product outlet pipeline 7
Flow out and reclaim.
When carrying out the filtration of single greasy dirt, by the inlet tube mouth of the heavy water storage barrel 2 not being connected with self priming pump 3
Stop valve, two loop cutoff valves 11, filter inlet stop valve 13 and air relief valve 14 cuts out, impurity mistake
The filtering outlet stop valve 15 of filter device 4 is closed, and opens self priming pump 3, and heavy water is by the heavy water storage barrel connected
2 enter greasy dirt filter 5 filters, and the finished product after filtration flows out through product outlet pipeline 7 and reclaims.
When needing contaminant filter such as secondary filter, the most first product outlet stop valve 71 is closed, by contaminant filter liquid
The loop cutoff valve 11 of closed circuit 9 is opened, heavy water after filtering for the first time through contaminant filter liquid closed circuit
After 9 carry out contaminant filter, being opened by outlet shutoff valve 71, the finished product after filtration flows through product outlet pipeline 7
Go out to reclaim.
When needing greasy dirt to filter such as secondary filter, the most first product outlet stop valve 71 is closed, by greasy dirt filtrate
The loop cutoff valve 11 of closed circuit 10 is opened, and heavy water loops back through greasy dirt filtrate after filtering for the first time
After road 10 carries out greasy dirt filtration, being opened by outlet shutoff valve 71, the finished product after filtration is through product outlet pipeline 7
Flow out and reclaim.
When the heavy water in the heavy water storage barrel 2 being connected with self priming pump blots, control system 1 monitoring sucks stream
When gauge 36 flow is zero, suction tube switching instruction device is reported to the police, and workman switches suction tube by tee ball valve
To another heavy water storage barrel 2, it is achieved do not shut down switching suction tube, be greatly improved filter efficiency, it is to avoid repeat
Shut down, extension device service life.
Greasy dirt filtration pressure on the contaminant filter differential manometer 47 or greasy dirt filter 5 of device for filtering impurities 4
The pressure reduction of difference meter 47 exceedes limit value, indicates device to report to the police by the filter replacement of control system, and prompting is changed
New filtration core, automatic safe.
Owing to device for filtering impurities is overall basket type filter core structure, when changing filter element, hanging device only need to be used
Whole hand basket is proposed, the overall basket type filtration core more renewed；Greasy dirt filter is overall hand basket
Formula filter core structure, uses pull bar molectron to fix, only need to be by pull bar molectron from greasy dirt mistake during replacing filter element
Getting loose on filter upper cover plate, proposed by whole greasy dirt filtration core with hanging device, the greasy dirt filtration core more renewed is i.e.
Can.Use said structure, workman can be avoided to be radiated when changing filter element；Filter liquid by filtration core simultaneously
Filtration outward makes into from filtration core outer toward inner filtration, owing to the impurity the contained volume in hand basket is far longer than filtration
The volume of in-core, thus it is greatly improved use time and the life-span of filtration core.
After having filtered, filtration inlet stop valve 13 and air relief valve 14 are opened, treat the pressure of Pressure gauge 12
When reverting to normal barometric pressure, close self priming pump, prevent the finished product suck-back filtered from entering in self priming pump.Then lead to
The pipe joint crossing end connects external pressure air hose, purges device interior by compressed air, by residual
The heavy water residual liquid staying equipment purges away, without manual cleaning, it is to avoid residual liquid radiates.
Described above is exemplary rather than restrictive.Can be anticipated by described above those skilled in the art
Knowing and plant change and deformation to the many of the present invention, it also will fall within the spirit and scope of the invention.
