Abstract
The invention relates to a net-cage type filter for spray and drip irrigation and an application method thereof. The net-cage type filter comprises a filter frame and a filter screen. The filter screen is arranged in the filter frame. The key point of the design is that the filter also comprises a backwash tank. The backwash tank is fixed at the top of the filter frame. The bottom inside the backwash tank is provided with a water through-hole which is communicated with the inside of the filter frame, and the water through-hole is provided with a sealed cap which can overturn. The backwash tank is provided with a control switch for controlling the sealed cover to overturn so as to open the water through-hole. The top of the backwash tank is provided with a water inlet interface, and a side face of the backwash tank is equipped with a water outlet interface. The above structure is essentially formed by additionally arranging a backwashing device, namely the backwash tank, based on an existing origin filter net cage. The filter screen undergoes regular backwashing by the backwash tank. Thus, the filter screen is rapidly cleaned so as to effectively guarantee filtering effect of the filter screen and prolong service life of the filter screen. Meanwhile, the blocking problem of spray and drip irrigation pipelines is effectively minimized, and implementation of spray and drip irrigation is more reliable.
Description
Technical field
The present invention relates to sprinkling irrigation equipment, is a kind of spray drop filling cage type filter and using method thereof.
Background technology
Filter is the key equipment of sprinkling irrigation, particularly slight irrigation (microspray irrigation and drip irrigation) system worked well.Conventional design middle filtrator is all arranged on pumping line, is namely " rear-mounted filtration ".Conventional filter has multiple, all there is following problem: 1, well strainer, laminated filter, one is that single filter retaining power is very little, 4-8 filter parallel connection is needed to use, cost (cost) is higher, and two is that multiple filter cleaning amount is very large, and relative to floating thing a large amount of in water, still not, well strainer often " is burst " capacity.2, sandstone formula filter, though retaining power is comparatively large, a large amount of floating thing blocks up in container, removes or very inconvenient, and price is ten hundreds of, needs often to change filter sand, and operating cost is also high, and general peasant household is more difficult bears.3, existing filter has " common fault ": be all that consequence is inner blocked, and need often to clear up, workload is very large thing " suction " filter floating in water.And use for a long time, filter effect is undesirable, and impurity and dirt easily enter pipe-line system, the delivery port (bore of water dropper is less than or equal to 1 millimeter) of block water irrigator, and the normal work of impact sprinkling irrigation, particularly affects the service life of drip irrigation pipe.Need to be improved existing spray drop irrigation filter for this reason.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide a kind of spray drop filling cage type filter and using method thereof to this area, make it solve existing spray drop fill system water inlet filter effect not good enough, cleaning filter is comparatively inconvenient, easily causes spray drop to fill with the technical problem of line clogging.Its objective is and to be achieved through the following technical solutions.
This spray drop filling cage type filter comprises filter frame, screen pack, and screen pack is placed in filter frame.Its structural feature is that this filter also comprises backwash casing, backwash casing is fixed on described filter frame top, backwash casing inner bottom part is provided with and the outlet pass communicated in filter frame, and outlet pass place is provided with the seal cover that upset is arranged, described backwash casing is provided with and controls the gauge tap that described outlet pass is opened in the upset of described seal cover, described backwash casing top is provided with into water interface, and side is provided with water outlet mouthpiece.Said structure, in fact set up back purge system on the basis that existing top filters net cage, i.e. backwash casing, by backwash casing, regular backwash is carried out to screen pack, realize screen pack Rapid Cleaning, thus effectively can ensure the filter effect of screen pack, extend screen pack service life.Meanwhile, effectively reduce the problem that spray drop fills with pipeline blockage, make spray drop filling implement more reliable.
Concrete structure is: described filter frame is cuboidal frame structure, described screen pack is and mates in filter frame and top hollow out, the edge at filter frame top is provided with fixing hole, described backwash bottom half is provided with the base closed with described filter frame top fit, be connected by securing member locking between base with fixing hole, and base is provided with conducting filter interior and outside port.More for convenience, described port conveniently connects the inlet pipeline of water pump to this anatomical connectivity.
Be closed with a side bottom described filter frame.This structure is when considering the invention process, mainly near current bank, therefore needs to prevent bank mud from sucking, and meanwhile, when more shallow current, needs to prevent base sludge from sucking, therefore to be designed to bottom filter frame with a side be closed.
In described backwash casing, filter is set near described water outlet mouthpiece place.By setting up filter, filter effect of increasing water quality further, and when backwash casing carries out backwash operation, also certain flushing operation can be carried out to this filter.The mounting structure of concrete filter is: described backwash casing top is provided with sealing and renovates, and backwash casing inner bottom part is provided with the slot of grafting filter, and the opening that filter is formed after renovating unlatching by sealing inserts in described slot.
Described gauge tap comprises the rotary handle that seal rotary is arranged at described backwash body side, rotary handle inside is provided with control lever, be connected by rope between control lever with described seal cover, when rotary handle rotates, seal cover is flipped open described outlet pass.This structure controls similar with the bath of existing flushing toiler in fact, and the main distinction to be between gauge tap and backwash casing, for seal, to prevent from leaking.
Described backwash casing top is provided with pump Connection Block, and connect water pump by this pump Connection Block, water feeding of water pump pipeline stretches in the screen pack in described filter frame, and water pump water outlet pipeline connects described water inlet interface.By water pump and backwash casing one being installed, structure is comparatively compact, and operation uses more for convenience.
This spray drop filling using method of cage type filter is: the water inlet interface of described backwash casing connects the outlet pipeline of water pump, the inlet pipeline of water pump stretches in described screen pack, the outlet pipe of backwash casing connects spray drip irrigation pipeline, open water pump, top water filtration is realized by screen pack, water after filtration enters in described backwash casing, then leads to spray drip irrigation pipeline by water outlet mouthpiece, realizes sprinkling irrigation operation; When after use a period of time, switch off the pump, open described gauge tap, the seal cover of described backwash bottom half is opened by gauge tap, described outlet pass is opened, and the current in backwash casing pour fast in described screen pack under Gravitative Loads, namely realize screen pack backwash operation; After backwash completes, closing control switch, opens described water pump, continues to implement sprinkling irrigation.
Structure of the present invention is comparatively simple, by setting up filtration net cage at spray drop fill system top, effectively can filter the water inlet impurity of spray drip irrigation pipeline, reduces spray drip irrigation pipeline middle filtrator pressure, reduces blocking, improve filter effect, increase the service life.And set up backwash casing, facilitate and regular top screen pack to be cleaned, ensure its filter effect.The filter being suitable as all kinds of spray drop fill system uses, or the structure of similar filter is improved.
