The double-filtration of filter 2 and the second filter 6 may finally go in water removal to be greater than the impurity of 150 mesh.
The course of work of the invention is as follows:
Open the first shut-off valve 20 and the second shut-off valve 21 manually first, PLC control system starting automatically turns on the first solenoid valve
15, second solenoid valve 16, third solenoid valve 17.Water enters water tank 4 from water inlet pipe 1, through first filter 2, from the outlet of water tank 4
Enter the second filter 6 through the second pipeline 5, enters water storage box 8 through the second filter 6, third pipeline 7, third solenoid valve 17；When
When water level in water storage box 8 reaches setting height, liquid-level switch 82 sends a signal to PLC controller, PLC controller control first
Solenoid valve 15 is closed, and can be extracted water sample from the intake 81 on water storage box 8 at this time and be analyzed.
Using first filter 2 and the second filter 6, it ensure that and carried out comprehensively and effectively into the water sample in water storage box 8
Pretreatment.
It, can also be by water come the function of reverse cleaning first filter 2 and the second filter 6, specifically in the present embodiment
It is as follows:
To the reverse cleaning of first filter 2: PLC control system starts second solenoid valve 16 and the 5th solenoid valve 19, in water tank 4
Water due to gravity through second solenoid valve 16, the first pipeline 3, first filter 2, the 5th solenoid valve 19 and drainpipe 10 be discharged.
Meanwhile the contrary of first filter 2 is flowed through when water (flow) direction and filtering when the draining, so playing reverse cleaning first
The purpose of filter 2.
To the reverse cleaning of the second filter: PLC control system starts third solenoid valve 17, while opening third manually and cutting
Only valve 22, water in water storage box 8 due to gravity through third solenoid valve 17, the 7th pipeline 14, the second filter 6, the 7th pipeline 14,
Third shut-off valve 22 and drainpipe 10 are discharged.Meanwhile the side of the second filter 6 is flowed through when water (flow) direction and filtering when the draining
To on the contrary, so playing the purpose of the second filter of reverse cleaning 6.
The above process had both achieved the purpose that reverse cleaning filtering device also acted as the work of discharge water tank 4 and the water in water storage box 8
With.
The present embodiment also has the anti-cleaning filter function of air pump 24, and air pump 24 instead cleans the course of work of filter such as
Under:
It is first shut off all shut-off valves and solenoid valve, the 4th solenoid valve 18 and the 5th solenoid valve are opened in then PLC controller control
19 and booster air pump 24, high pressure draught is successively through check valve 23, air inlet pipe 11, third pipeline 7, the second filter 6, the second pipeline
5, the 5th pipeline 12, the 4th solenoid valve 18, the first pipeline 3, first filter 2, the 6th pipeline 13 and drainpipe 10 by pipeline and
Residual water discharge in filter.
Since the mesh number of first filter 2 is greater than the mesh number of the second filter 6, so the high pressure draught through air pump 24, it can
With will be in the impurity reverse cleaning to first filter 6 in the second filter 2 and finally through drainpipe 10 by impurity reverse cleaning
Discharge.
