Description

A kind of floatation type slight irrigation filtration system
Technical field
The invention belongs to filtration system technical field before slight irrigation pump, and in particular to a kind of floatation type slight irrigation filtration system.
Background technology
The reasonable disposition of irrigation system stem filtration system plays vital to the normal operation of whole irrigation system Effect, if filter plant is supporting or type selecting is improper, it will the paralysis of whole irrigation system is caused, so will be scientifically and rationally Select stem filtration system.The filter of field of agricultural irrigation application at present mainly has laminated filter, sandrock filter, centrifugation Filter, well strainer and self-cleaning filter, usually according to the difference of water quality in, by these different types of filterings Device is combined use, removes different impurities and organic matter in water source respectively.However, the characteristic that these filters share is exactly Filtered after belonging to pump, filtering is exactly after water pump pressurizes to current after pump, enters back into filter and is filtered, existing to ask Topic is exactly that filter can be hindered current in itself, the loss of flood peak is produced, wherein the loss of flood peak of most widely used sandrock filter 10 meters can be reached, these losses can cause the increase of water pump match power, increase operating cost, while filtration system most critical Problem is the cleaning after filtering, and cleaning is backwashed by clean water after the blocking of this several filter at present, Sewer caused by backwash can cause the water waste of a quarter, reduce the efficiency of filtering and the utilization rate of water.Moreover, pass The filtration system of system has that floor space is big, and connecting pipe is more, and installation is safeguarded complicated, is unfavorable for reclaiming and takes care of.
The content of the invention
The present invention provides one kind for overcome the deficiencies in the prior art and mutually ties self-cleaning filter with floating water pump The floatation type slight irrigation filtration system of conjunction.
The present invention adopts the following technical scheme that a kind of floatation type slight irrigation filtration system, it is special to solve above-mentioned technical problem Levy and be to include pontoon, pontoon top is provided with reducing motor and pump water inlet, and pontoon bottom is provided with by-pass filtration net and two level Screen pack, described reducing motor are fixed on pontoon bottom plate by electric machine support, and the side of reducing motor output shaft passes through biography Motivation structure is connected with lifting screw, and the top of transmission mechanism, which is provided with, to be used to control lifting screw to move up and down the upper and lower of extreme position Proximity switch, lifting screw run through pontoon bottom plate by sealing device, and the bottom of the lifting screw is provided with hairbrush fixed mount, in hair Brush fixed mount is provided with the hairbrush to match with secondary filtration net outer rim, and lifting screw moves up and down stroke and secondary filtration net Highly consistent, one end sealing of pump water inlet is connected through pontoon bottom plate with the delivery port on secondary filtration net top, and water pump enters The other end of water pipe is connected with the water inlet of water pump, and the delivery port of water pump is connected with pumping line, described secondary filtration net The inner side of by-pass filtration net is arranged at, the aperture of the secondary filtration net is less than the aperture of by-pass filtration net.
Further preferably, described secondary filtration net is sintered meshwork, the wedge-shaped filter cylinder of 304 Steel materials or 316 Steel materials Wedge-shaped filter cylinder.
Further preferably, described water pump is arranged on pontoon or is arranged at bank.
Further preferably, described pontoon afterbody is provided with propeller.
Further preferably, described secondary filtration net is evenly equipped with least two sets in pontoon bottom.
Of the invention can realize self-cleaning filter and floating water pump combination will filter before filtering is changed into pump after pump, and And the device is swum on the water surface, go for a variety of water source forms such as river, lake, reservoir, swag and cistern, With small volume, it is not take up field arable land, connection simply, non-recoil washes blowdown water loss and without head damage existing for filtering after pump The advantages such as mistake, can perform to maximum, suitable for common water-saving irrigation system and emergent drought resisting system by the lift of water pump.
