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:
Body 13 is a circular cylinder body structure being supported by frame 10, at cylindrical shell two ends, cap seal has intake end cover 8, draining end cap 17 respectively, in the cylindrical shell bottom that is positioned at intake end cover 8 ends, be provided with raw water inlet 11, in the cylindrical shell bottom that is positioned at discharge ends and covers 17 ends, be provided with and produce water delivery port 16; On raw water inlet 11, be provided with into water pressure difference transmitter interface 12, on product water delivery port 16, be provided with and produce differential water pressures transmitter interface 14;
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;
