During work, operate the electric control starting key button of electrical control cubicles (1) cabinet door (2) shop front or open handle lock startup cabinet door (2) The electric control starting key button that door internal control card is arranged, automatically controlled to blowdown respectively by each connection wire (15) by electrical control cubicles (1) Valve (16), electric control exhaust valve (28), motor reducer (30), proximity switch (35), differential pressure controller (37) and temperature-sensing element (38) operating current or working signal of awaiting orders it are passed through.Open clear water gate valve (20) and former Water gate valve (7), make that pipeline is unimpeded all to be entered Duty.In sterilization duct (36) given by pipe fitting (8), circulating water liquid is fed to former water inlet (6) when raw water pipeline or with water pump Time, along bearing axle, the kickboard (32) arranged in sterilization duct (36) epimere will be that the center of circle carries out floating mobile, make entirety or The induction pieces (34) that split connects leaves proximity switch (35) correspondence position, and vicarious proximity switch (35) loses induction part (34) Control after, simultaneously can automatically run work by the electric control gear in touch-control electrical control cubicles (1).Electrical control cubicles (1) is by the sterilization set Electric current is passed through nominal density to respectively left pole plate (21) and right pole plate (5) by left pole plate wire (22) and right pole plate wire (4) Sterilization operation electric current, make former water when by instantaneous sterilization room (39), shock by electricity with high-density current and high potential difference voltage Destroy and after instantaneous sterilization, the antibacterial contained is killed with virus and insect moment, the former water processed by instantaneous sterilization in former water Central space in tank body (23) is fed from top inlet orifice again through ring flange (33) and pipe fitting (31).In feeding in tank body (23) The sterilized water liquid in portion or the water liquid fed from pipe fitting (31) by other method without sterilization duct (36) sterilization, can will feed Water liquid through drum type brake fine filter (25) and drum type brake orifice plate (24), clean clear water is leached to periphery, from periphery filter After the clear water gone out collects, all direct out through clear water output (19) and confess or outwards confess through clear water gate valve (20).When work one If drum type brake fine filter (25) inner surface is when hanging with pollution layer after the section time, the inside of drum type brake fine filter (25) and Outside will produce differential water pressures timed unit in, differential pressure controller (37) is by signal conductor touch-control electrical control cubicles (1) or electricity Control device runs to blowdown electrically-controlled valve (16) and the work of (30) time periods of Combined motor reductor by wire (15) Electric current.Combined motor reductor (30) drives the power transmission shaft (18) with framework and scrubbing brush (10) to rotate, the scrubbing brush of rotation (10) by scrubbing brush (10) outside lousiness, the body refuse of drum type brake fine filter (25) inner peripheral surface is wiped off or brushed off, brush off mud Slag sinks in the sludge outlet (13) of low head (11) bottom, is more outwards arranged from sewage draining exit (17) by blowdown electrically-controlled valve (16) Go out or discharge through pipeline with manual blowdown valve.When scraping body refuse or after brush body refuse completes, drum type brake fine filter (25) Inside and outside hydraulic pressure will balance, differential pressure controller (37) by the timed unit in signal conductor touch-control electrical control cubicles (1) or Electric control gear, stops to motor reducer (30) and blowdown electrically-controlled valve (16) operating current, makes motor reducer (30) and blowdown Electrically-controlled valve (16) is suspended, then the desludging of wait next period works or directly initiates typamatic key button and carries out continuous work Make.When sterilization duct (36) endogenous cause of ill Changes in weather or other reason cause water liquid temp too high or too low, temperature-sensing element (38) can immediately by wire touch-control electrical control cubicles (1) out of service and report to the police instruction, wait pending after by manual reset or temperature Automatically reset after recovery.If by Pipe installing or other reason when gas occurs in tank body (23) top, upper cover side Mechatronic intelligent electronic-controlled air bleeding valve (28) can work automatically, is externally discharged by trachea by waste gas, and the drained rear Mechatronic intelligent electronic-controlled of gas is arranged Air valve (28) can automatic pause or operation of awaiting orders.When the former water in former water time-out or sterilization duct (36) remains static, Kickboard (32) can automatically reset because losing current external force with the induction pieces (34) of integrated connection, the proximity switch simultaneously sensed (35) produce automatically controlled signal, close the electric current sterilizing unit in electrical control cubicles (1) and electric-controlled parts by wire, make at whole set equipment Automatically run when suspending armed state or wait water liquid again flows.As needed disinfection system operable cabinet door out of service (2) sterilization of surface or inside stops key button, makes disinfection system power-off stop, and filtration system still can be properly functioning.If desired for whole Machine equipment quits work, and the key button that always stops of operable cabinet door (2) surface or inside makes complete machine power-off stop.When needs are again started up During operation, the startup key button of operable cabinet door (2) surface or inside makes complete machine bring into operation again or operation of awaiting orders, if sterilization tube The water liquid stream in road (36) is dynamic or confesses, and the induction pieces (34) that kickboard (32) connects will float, inductive proximity switch (35) immediately The most automatically touch-control complete machine runs or single system runs.Above-described embodiment has formed tap water instantaneous sterilization parasite killing The whole work process of filter plant continuously, it is achieved that task of the present utility model.
