Description
Technical field
The present invention relates to a kind of oil mist filter, what particularly relate to a kind of exhaust-gas treatment field can automatic cleaning type machinery oil mist resistant filter.
Background technology
Now domestic mechanical processing industry, in the process cooled casting workpiece, generally can use emulsion or cold oil, thus produces a large amount of mist of oil oil smoke, affects the production environment of factory and the healthy of staff.Current mechanic factory workers is avoid this mist of oil oil smoke on the impact of environment, two kinds of methods below normal employing: one is the generation as far as possible reducing pollutant from pollution sources, this method needs the character of foundation product and processing capacity to determine, so be difficult to be controlled.Two is install powerful exhaust apparatus, and by oil smoke mist of oil and dust emission to outdoor, this kind of method not only wastes electric energy, and comparatively greatly, oil smoke, the mist of oil of discharge also can continue contaminated environment to noise ratio.
In sum, engineering shop needs to use a kind of oil mist filter, the harmful substance in purifying air, ensure the environmental quality in workshop and workman healthy.Although strict requirement is not also done to engineering shop's gaseous mass at present by China, but in some developed countries, the configuration of oil mist filter uses and has been listed in industry regulation, and in engineering shop of China, be equipped with oil mist filter has also become a kind of trend.But current machinery oil mist resistant filter is difficult to remove the oil droplet adhered on metal filter screen wire side usually, need regularly to metal filter screen disassembly, cleaning, maintenance is very large.
Summary of the invention
The present invention devises one can automatic cleaning type machinery oil mist resistant filter, solves the cleaning difficulty that machinery oil mist resistant filter brings, overcomes and need regularly often to change metal filter screen, the shortcomings such as maintenance is large.
Technical scheme of the present invention is: one can automatic cleaning type machinery oil mist resistant filter, comprise filtration system and automatic cleaning system, described filtration system comprises single filter and cascade filtration, described single filter comprises double layer of metal screen pack, ground floor one-level metal filter screen is parallel with second layer one-level metal filter screen to be fixed on one-level metal filter screen framework, cascade filtration system comprises double layer of metal screen pack, and ground floor secondary metal filter screen is parallel with second layer secondary metal filter screen to be fixed on secondary metal filter screen framework; Described automatic cleaning system comprises reducing motor, pinion, gear wheel, eccentric shoe, gangbar, hairbrush, hairbrush connecting rod, nozzle; Described reducing motor is connected with pinion by connecting axle, the tooth of pinion is engaged mutually with the tooth of gear wheel, and gear wheel is furnished with eccentric shoe, and eccentric shoe is enclosed in the slideway of gangbar, one end of gangbar is connected with hairbrush, is connected between two hairbrush by hairbrush connecting rod; With coil tension spring in described gangbar; Every grade of metal filter screen framework two ends are equipped with differential pressure pickup; Two nozzles are provided with after cascade filtration; Air outlet sets out tuyere flange and centrifugal blower.
Air distribution plate is provided with in ground floor one-level metal filter screen front end.
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 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: start working after automatic cleaning system acknowledge(ment) signal, reducing motor and magnetic valve are opened simultaneously, reducing motor drives pinion rotation after opening, pinion drives bull gear drive, pinion is used to drive the structure of gear wheel can reduce the pinion rotation one week time used, thus reduce rotating speed, with the speed of applicable brush movement; Gear wheel is furnished with eccentric shoe, and eccentric shoe moves along with the rotation of gear, and gangbar also waves band electric brush along orbital motion thereupon; Gangbar carries out self-regulation length with coil tension spring, carrys out applicable hairbrush track; Magnetic valve is opened simultaneously, and nozzle is started working, and is sprayed by clear water in metal filtration online, rinses the oleaginous material under hairbrush brush, makes it flow out with water, discharged from bottom by blowoff valve.
Be furnished with differential pressure pickup, the peak of set pressure differential at every grade of metal filter screen framework two ends, when any single filter pressure at two ends difference arrives peak, signal is passed to master control cabinet by differential pressure pickup, and master control cabinet controls automatic cleaning system and starts 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 set scavenging period according to actual conditions, and after time is up, automatic cleaning system quits work, and filtration system is started working.
Beneficial effect of the present invention is: application native system can realize filtering and cleaning automatically completes, can the duty of automatic cleaning type mechanical filter without the need to staff's supervision during operation; Also without the need to manual cleaning metal filter screen, have easy to maintenance, save the advantage of manpower.
