The specific embodiment
See Fig. 1, Fig. 2, metal film differential pressure filtering machine, the present invention is characterised in that, includes body, is positioned at the filter mechanism of body, the backwashing mechanism that is positioned at filter mechanism, the transmission mechanism being connected with backwashing mechanism, is positioned at the pollution discharge mechanism of filter mechanism; Wherein:
Filter mechanism is the tube structure with mesh, is divided into 22 sections two sections of 21 sections of coarse strainers and fie screens, is connected with a dividing plate to body cylinder inboard wall between two sections; 21 sections of coarse strainers are communicated with raw water inlet 11,22 sections of fie screens with produce water delivery port 16 and be communicated with;
Backwashing mechanism comprises the hollow shaft 25 with body cylindrical shell concentric, is arranged on the pollution-absorbing nozzle that is positioned at the fine filtering network segment 26 in hollow shaft; Hollow shaft 25 front ends are stretched out with transmission device and are connected by intake end cover 8; The front end of hollow shaft is high-pressure water inlet chamber 7, and high pressure backwashing pump water inlet pipe 9 is communicated with high-pressure water inlet chamber 7; High pressure backwashing pump water inlet pipe 15 is communicated with product water delivery port 16; Backwash high-pressure pump 22 is set to supply water in body by high pressure backwashing pump water inlet pipe 9; On 22 sections of the fie screens of body 13, be provided with pressure difference transmitter 23, on high pressure backwashing pump water inlet pipe 9, be provided with high pressure backwash pressure table 24;
Transmission mechanism comprises driving motor 1, electric cabinet 2, travel switch A3, driving block 4, cover 5, travel switch B6 are in transmission connection;
Pollution discharge mechanism comprises with hollow shaft 25 and being communicated with, and is positioned at the blowdown chamber 18 outside draining end cap 17, the concentrated water discharge pipe 19 being communicated with blowdown chamber 18.
Working method of the present invention is:
The former water of pressure is by 11 raw water inlets, with external pressure mode 20 coarse strainers of flowing through, filtering larger particles impurity, and 20 coarse strainer water outlets enter fie screen with inner pressed, and further the fine impurities in trap water, is finally sent to and is used water spot by delivery port.
Along with the accumulation of various pollutants in filter medium in 21 fie screen inner sides, filtration channel is blocked, intake-outlet pressure reduction increases gradually, when pressure reduction reaches default definite value, 12 pressure difference transmitters that are connected in intake-outlet just convert the pressure difference signal detecting to the current signal of 4-20mA, pass to 2 control systems, backwash frequency also can preset 24 high pressure backwash pressure tables by the time simultaneously, when reach default definite value running time, system starts driving motor 1 and 22 backwash high pressure pumps automatically, now transmission device drives the contaminants collector that suction nozzle is housed to do rotation and horizontal back and forth movement in filter screen inner side, filter screen is carried out to high pressure backwash, backwash water sees through filter screen, together with the impurity of peeling off from filter screen, by suction nozzle, sucked rapidly contaminants collector, deliver to 18 blowdown chambers, finally by sewage draining exit, discharged.
After a backwash stroke, pressure reduction reduces, and each parts reset, and system reenters normal operating condition.
