At ground floor one-level metal filter screen front end, be provided with air distribution plate.
Described filtration system comprises single filter and cascade filtration, its technical essential is: described single filter comprises double layer of metal screen pack, first layer metal screen pack inside is to be the netted of 1～2mm stainless steel steel wire staggered by diameter, and the steel wire that second layer metal screen pack is 0.01～0.05mm by diameter interlocks and forms the cellular of minim gap.
From its technical essential, be: after automatic cleaning system acknowledge(ment) signal, start working, reducing motor and magnetic valve are opened simultaneously, reducing motor drives pinion rotation after opening, pinion drives gear wheel to rotate, use pinion to drive the structure of gear wheel can reduce gear and rotate one week time used, thereby reduced rotating speed, to be applicable to the speed of hairbrush motion; On gear wheel, be furnished with eccentric shoe, eccentric shoe moves along with the rotation of gear, and gangbar is also waved band electric brush along orbital motion thereupon; In gangbar, with coil tension spring, carry out self-regulation length, be applicable to hairbrush track; Simultaneously magnetic valve is opened, and nozzle is started working, and clear water is sprayed in metal filtration online, rinses the oleaginous material under hairbrush brush, and it is flowed out with water, from bottom, by blowoff valve, discharges.
At every grade of metal filter screen framework two ends, be furnished with differential pressure pickup, the peak of set pressure differential, when the poor arrival peak of any single filter pressure at two ends, differential pressure pickup passes to master control cabinet by signal, and master control cabinet is controlled automatic cleaning system and is started working.Automatic cleaning system utilizes reducing motor to control hairbrush work, scrubs wire netting surface, and utilizes solenoid control nozzle automatic spray.Default scavenging period is 10 minutes, also can to scavenging period, set according to actual conditions, and after time is up, automatic cleaning system quits work, and filtration system is started working.
The beneficial effects of the utility model are: application native system can be realized filtering and cleaning and automatically complete, duty that can automatic cleaning type mechanical filter without staff's supervision during operation; Also without manual cleaning metal filter screen, have easy to maintenance, the advantage of saving manpower.
