Embodiment
Technical scheme is described in detail with reference to accompanying drawing.Filtration system before a kind of self-cleaning pump, including pontoon 6, float
The top of ship 6 is provided with soil pick-up pump 1 and reducing motor 2, and the bottom of pontoon 6 is provided with sealed cylinder 12, by-pass filtration net 15 and secondary filtration
Net 13, reducing motor 2 are fixed on the bottom plate of pontoon 6 by electric machine support 4, and the side of the output shaft of reducing motor 2 passes through driver
Structure is connected with rotary shaft 3, and the rotary shaft 3 through the bottom plate of pontoon 6 and extends to the outside of pontoon 6, sealing drum by sealing device 9
Body 12 is sealingly fastened in the bottom of pontoon 6 position relative with rotary shaft 3, the sealed cylinder 12 by secondary filtration net 13 be separated into
Water cavity and water chamber, wherein intake antrum bottom are communicated by by-pass filtration net 15 with external source, the rotary shaft 3 on the inside of intake antrum
Hairbrush fixed mount 14 is provided with, the hairbrush 16 to match with the inner edge of secondary filtration net 13, intake antrum are provided with hairbrush fixed mount 14
Top is connected by sealing through the dirt sucking tube 10 of the bottom plate of pontoon 6 with the import of soil pick-up pump 1, the outlet of soil pick-up pump 1 by blow-off pipe and
Impurity collecting net 11 is connected, and water chamber is connected by pump water inlet 8 with the water inlet of water pump 5, the delivery port of water pump 5 and water pump water outlet
Pipe 7 is connected.Described secondary filtration net 13 is the wedge-shaped filter cylinder of sintered meshwork, the wedge-shaped filter cylinder of 304 Steel materials or 316 Steel materials.
Described water pump 5 is arranged on pontoon 6 or is arranged at bank.
In running of the present invention, the pontoon is placed on water float on the water surface, pumping line and bank are managed
Net is docked, and power supply pipeline is laid with pumping line, and switch board can be arranged on bank.After starting water pump, start
Draw water, water first passes around by-pass filtration net and large granular impurity is carried out into by-pass filtration.It should try one's best and ensure in upstream during actual use
The pre-filtering facilities such as trash rack, setting pot are set, reduce the filtering load of the filter.Water is after secondary filtration net filtration
Into in the sealed cylinder on the outside of secondary filtration net, the secondary filtration net can use wedge-shaped net cylinder, and the wedge-shaped net cylinder has knot
Structure is compact, and bearing capacity is strong, the advantages that easy cleaning.Wedge-shaped net is welded with twine, the trapezoidal shape in twine section, is used for
During the filtering, trapezoidal long side should be made to be located at inner side.Required according to filtering accuracy, select suitable filter screen mesh number.Impurity is trapped
On the inside of secondary filtration net, filter water enters cavity outer side seal cylinder and secondary filtration net through secondary filtration net,
Subsequently into pump water inlet, after water pump pressurizes, the water for meeting and irrigating and requiring is provided for field network.
After impurity more accumulates more inside the secondary filtration net, discharge capacity will result in influence, inside and outside secondary filtration net
Pressure difference increases, when reaching to a certain degree, it is necessary to cleaned.Cleaning frequency can carry out clear according to differential pressure pickup signal
Wash, a regular time can also be determined, after certain time is filtered, automatic start is clear by summarizing according to water quality situation
Wash.After switch board is to reducing motor signal, reducing motor starts to drive rotary shaft to rotate, rotary shaft and the hairbrush for being fixed with hairbrush
Fixed mount connects, and hairbrush starts to rotate, and hairbrush contacts with secondary filtration net inner surface, it becomes possible to scrubs the impurity of surface accumulation
Fall.When reducing motor starts, soil pick-up pump also starts, and the impurity that hairbrush scrubs off is together with water after dirt sucking tube is discharged to pipeline
In the impurity collecting net of face connection.The impurity collecting net mesh number is less than fie screen mesh number as far as possible, and the collecting net can stay impurity
Deposit and collect, be unlikely to reenter water body, reduce repetition filtering load.Soil pick-up pump and reducing motor all do not need power
It is too big, it becomes possible to meet blowdown and the power needed for hairbrush rotary motion.Work water pump can not be put aboard ship, can also be fixed
On bank somewhere, pump water inlet is connected with pump intake.
Have been shown and described above the general principle of the present invention, principal character and advantage, do not depart from spirit of the invention and
On the premise of scope, the present invention also has various changes and modifications, and these changes and improvements both fall within claimed invention
Scope.
