Fig. 1 is the present invention's intelligence food and drink sump oil separator structural representation.
See also Fig. 1, intelligent food and drink sump oil separator provided by the invention comprises profit Buffer Pool 1 and microcontroller 6, wherein, is provided with two blocks of electrolysis electrode plates 3 in the said profit Buffer Pool 1 at least, and said electrolysis electrode plate 3 links to each other with high frequency pulse power supply 2; The exit of said profit Buffer Pool 1 is provided with flow sensor 5 and flowmeter 4, and said microcontroller 6 links to each other with flowmeter 4, high frequency pulse power supply 2 and monitors Faradaic current in real time according to sump oil discharge.
Then introduce critical piece of the present invention below in detail:
But high frequency pulse power supply 2 is the automatic reverse high frequency electric source, produces maximum amplitude 50V, and frequency is at the square-wave waveform of 45KHZ, and output pulse width is adjustable, and the rated disspation of out-put supply is 350W, is the motive power of water-oil separating.When output waveform affacts the sewage from catering business the inside, can produce directed electromagnetic field, can make waste oil condense come-up rapidly, thereby reach the effect of water-oil separating.But the automatic reverse function can effectively be eliminated the residue on battery lead plate, and then reaches the function that battery lead plate exempts to clean.Because this power supply has the voltage monitoring function, when graphite electrode exhausted, the spacing of battery lead plate was strengthened, and then caused output voltage to increase; When output voltage surpassed setting value, microcontroller 6 produced the warning indication of changing electrode automatically, closes this supply unit simultaneously.This power supply can be exported effective current by real time on-line monitoring, and then regulates output pulse width, and this function makes this power supply can adapt to the sump oil water of various electrical conductivity automatically.Microcontroller 6 can be according to the effective current value of feeding back in real time; Automatically regulate output pulse width; And then the slope of the effective current of control output and the slope of effective voltage, thereby effectively suppress brine electrolysis, fundamentally solved the harm of the inflammable and explosive gas that produces because of brine electrolysis.
But the automatic reverse high frequency electric source preferably adopts the topology design of half-bridge circuit, has the autoelectrinic commutation function, and promptly CPU is according to the time of operation, the polarity of automatic switchover out-put supply, and switching-over realizes through switching-over CMOS pipe.Output band hardware PI regulatory function can be as required, setting voltage closed-loop control and current closed-loop control.The inner auxiliary switching power supply that also has 2 covers to isolate fully of this power supply: wherein one tunnel supply power to the microcomputer control panel; Another road is to supply power to power driving circuit.Adopting the mode of isolating is in order to improve reliability of products.
