Detailed description of the invention
Describe by reference to the accompanying drawings technical scheme of the present invention in detail. filtration system before a kind of self-cleaning pump, comprise pontoon 6, pontoon 6 tops are provided with soil pick-up pump 1 and reducing motor 2, pontoon 6 bottoms are provided with sealed cylinder 12, single filter net 15 and cascade filtration net 13, reducing motor 2 is fixed on pontoon 6 base plates by electric machine support 4, one side of reducing motor 2 output shafts is connected with rotating shaft 3 by transmission mechanism, this rotating shaft 3 runs through pontoon 6 base plates by sealing device 9 and extends to the outside of pontoon 6, sealed cylinder 12 is sealingly fastened in the position relative with rotating shaft 3, pontoon 6 bottoms, sealing cylindrical shell 12 is separated into intake antrum and water chamber by cascade filtration net 13, wherein intake antrum bottom communicates with extraneous water source by single filter net 15, the rotating shaft 3 of intake antrum inner side is provided with hairbrush fixed mount 14, on hairbrush fixed mount 14, be provided with the hairbrush 16 matching with cascade filtration net 13 inner edges, pontoon 6 base plates are run through at intake antrum top dirt sucking tube 10 by sealing is connected with 1 import of soil pick-up pump, soil pick-up pump 1 exports by blow-off pipe and is connected with impurity collecting net 11, water chamber is connected with water pump 5 water inlets by pump water inlet 8, water pump 5 delivery ports are connected with pumping line 7. described cascade filtration net 13 is the wedge shape filter cylinder of sintered meshwork, 304 Steel materials or the wedge shape filter cylinder of 316 Steel materials. described water pump 5 is arranged on pontoon 6 or is arranged at bank.
In running of the present invention, this pontoon is placed on to water float on the water surface, pumping line is docked with bank pipe network, lay with pumping line for electric line, switch board can be arranged on bank. Start after water pump, start to draw water, first water carry out single filter through single filter net by large granular impurity. When actual use, should ensure the pre-filtering such as trash rack, setting pot facility is set in upstream as far as possible, reduce the filtration load of this filter. The advantages such as water enters in the sealed cylinder in cascade filtration net outside after cascade filtration net filtration, and this cascade filtration net can adopt wedge shape net cylinder, and this wedge shape net cylinder has compact conformation, and bearing capacity is strong, easy cleaning. Wedge shape net is to be welded with twine, and twine cross section is trapezoidal shape, during for this filtration, should make trapezoidal long limit be positioned at inner side. According to filtering accuracy requirement, select suitable filter screen order number. Impurity is trapped within cascade filtration net inner side, and filtered water enters the cavity outside sealed cylinder and cascade filtration net through cascade filtration net, then enters pump water inlet, after water pump pressurization, irrigates for field pipe network provides to meet the water requiring.
After the more inner impurity of cascade filtration net more accumulates, discharge capacity will impact, and cascade filtration net inside and outside differential pressure increases, and while acquiring a certain degree, just need to clean. Cleaning frequency can clean according to differential pressure pickup signal, also can, according to water quality situation, determine a regular time by summing up, and when filtering after certain hour, automatically starts and cleans. Switch board to reducing motor signal after, reducing motor start driven rotary axle rotate, rotating shaft is connected with the hairbrush fixed mount that is fixed with hairbrush, hairbrush start rotate, hairbrush contacts with cascade filtration net inner surface, just can by surface accumulate impurity scrub off. When reducing motor starts, soil pick-up pump also starts, and the impurity that hairbrush scrubs off is discharged in the impurity collecting net that pipeline connects below through dirt sucking tube together with water. This impurity is collected mesh number and is less than fine filtering mesh number as far as possible, and this collecting net can be retained impurity to collect, and is unlikely to reenter water body, has reduced to repeat to filter load. Required power is too not large for soil pick-up pump and reducing motor, just can meet blowdown and the hairbrush required power that rotatablely moves. Work water pump can not put aboard ship, also can be fixed on bank somewhere, and pump water inlet is connected with pump intake.
More than show and described general principle of the present invention, principal character and advantage, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present invention.
