Description

The timing automatic flusher of filter membrane
Technical field
The utility model relates to a kind of automatic flushing device that is used for the filter membrane of rinse water treatment facility.
Background technology
Membrane filter technique is widely used in the water treatment facilities, and it is simple in structure, and energy-conserving and environment-protective.But its filter membrane also can be subjected to medium pollution and inefficacy gradually in long-time running, therefore, must regularly clean, to recover its filtration, separating medium function.At present, millipore water is handled and is equipped in the running, and its contaminated filter membrane is generally adopted the chemical agent cleaning method, cleans once in about 5~6 months.The shortcoming that this cleaning method exists is: the cleaning outaged equipment time is long; Manual operations, troublesome poeration, labour intensity is big; Chemical agent use cost height; The discharging of chemical cleaning solution causes bigger pollution to environment.
Summary of the invention
The purpose of this utility model is to provide a kind of timing automatic flusher of the filter membrane that does not produce environmental pollution that can prolong the filter membrane Chemical cleaning cycle greatly for the membrane filter technique water treatment facilities.
Technical solution of the present utility model, be on the basis of the chemically-cleaning device of original configuration, to carry out technological improvement, promptly on the inlet pipeline of former cleaning fluid tank and on the dense water out rinse water delivery pipe of molecular filter a magnetic valve is being set respectively, and on the cleaning fluid tank, is setting up two automatically controlled liquid level gauges.Concrete scheme is: it comprises molecular filter, cleaning fluid tank and scavenging pump, the import of its cleaning fluid tank by the control valve valve on pipeline and the described molecular filter product water out pipeline before pipeline section be connected, the scavenging pump import is connected by the outlet of pipeline with the cleaning fluid tank, scavenging pump outlet then is connected by pipeline section behind the check-valves valve on pipeline and the molecular filter inlet pipeline, the dense water out of molecular filter is connected with the concentrated water discharge pipe that is provided with control valve, be connected to the rinse water delivery pipe and draw before the control valve of molecular filter concentrated water discharge pipe, and on the rinse water delivery pipe, magnetic valve is installed, on the connecting pipe between molecular filter product water out pipeline and the cleaning fluid tank, magnetic valve is installed, the cleaning fluid tank is provided with automatically controlled liquid level gauge down and the automatically controlled liquid level gauge of going up, the circuit while and the raw water pump circuit of the magnetic valve on described molecular filter product water out pipeline and the cleaning fluid tank connecting pipe, the automatically controlled liquid level gauge circuit of going up is connected, the circuit of magnetic valve while and raw water pump circuit on the described rinse water delivery pipe, automatically controlled liquid level gauge circuit down, the scavenging pump circuit is connected.
The beneficial effects of the utility model are: adopt initial product water to make cleaning fluid, short period, short time are carried out timing, automatic, standardization cleaning to filter membrane, thereby make filter membrane in long running time, remain good filtration, separating property, improve water treatment efficiency greatly; The Chemical cleaning cycle stretch-out that makes filter membrane has prolonged the service life of filter membrane more than one times effectively, has saved production cost, and has alleviated the environmental pollution that causes because of the chemical cleaning solution discharging.This apparatus structure is simple, and operation is convenient automatically, good reliability.
Description of drawings
Accompanying drawing is the utility model general structure schematic diagram.
The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
A kind of technological process of water treatment facilities is: former water 1 is by the import of pipeline 2 input raw water pumps 3, the import that the outlet of raw water pump 3 is established the molecular filter 7 of filter membrane 8 in being connected to by pipeline 6, Pressure gauge P is installed on the pipeline 6 successively, controlling valve 4, check-valves 5, the product water out of molecular filter 7 is by being provided with Pressure gauge P, the pipeline 9 of controlling valve 10 is connected to the import of product water tank 11, the outlet of product water tank 11 is equipped with controlling valve 12, the dense water out of molecular filter 7 is connected with the delivery pipe 13 of band controlling valve 14, before the controlling valve 14 of delivery pipe 13, draw and be connected to cleaning fluid discharge pipe 15, Pressure gauge P and magnetic valve 16 are installed on delivery pipe 15, draw on the pipeline section before the controlling valve 10 of the product water out pipeline 9 of molecular filter 7 and be connected to the import that the pipeline 18 that is provided with magnetic valve 17 is connected to cleaning fluid tank 21, cleaning fluid tank 21 is provided with automatically controlled liquid level gauge 19 down and the automatically controlled liquid level gauge 20 of going up, the outlet of cleaning fluid tank 21 is connected to scavenging pump 23 imports by pipeline 22, the outlet of scavenging pump 23 is connected on the pipeline section behind raw water pump 3 outlet conduits 6 upper check valves 5 by pipeline 25, and check-valves 24 and Pressure gauge P are installed on the pipeline 25.The circuit of the magnetic valve 17 on above-mentioned molecular filter product water out pipeline and the cleaning fluid tank connecting pipe is connected with the circuit of raw water pump 3, the automatically controlled circuit of going up liquid level gauge 20 simultaneously, and the circuit of magnetic valve 16 is connected with the circuit of raw water pump 3, the circuit of automatically controlled liquid level gauge 19 down, the circuit of scavenging pump 23 simultaneously on the rinse water delivery pipe.
The running of this device: after raw water pump 3 start operations, circuit control is opened magnetic valve 17 simultaneously, so the initial product water of molecular filter 7 promptly injects cleaning fluid tank 21, when water full when cleaning fluid tank automatically controlled goes up liquid level gauge 20, send the signal of telecommunication magnetic valve 17 cuts out, the product water of molecular filter 7 promptly flows into product water tank 11; The timing automatic cleaning frequency of filter membrane is freely to set, generally can be made as 2~3 hours, arrive when setting time cleaning frequency, raw water pump 3 promptly stops, scavenging pump 23 is opened automatically, magnetic valve 16 is opened automatically on the rinse water delivery pipe, initial product water in the cleaning fluid tank 21 washes through the filter membrane 8 in 23 pairs of molecular filters 7 of scavenging pump, when the liquid level of cleaning fluid tank is reduced to automatically controlled time liquid level gauge 19, sending the signal of telecommunication stops scavenging pump 23, magnetic valve 16 cuts out automatically on the rinse water delivery pipe, and raw water pump 3 is opened again.Flushing process is approximately one minute.So, press the operation of setting cycle repetitive cycling.
