Description
Technical field
The utility model relates to a kind of automatic backwash well strainer that is used for the drip irrigation stem.
Background technology
Along with the rise of water-saving agriculture, the drip irrigation and spray irrigation technology is just used more and more widely, develops various drip irrigation and spray irrigation equipment according to agriculture requirement, and its middle filtrator is a nucleus equipment.At present usefulness more is centrifugal, sandstone formula, net formula or laminated filter.
Well strainer is simple in structure, and it is low to make use cost, and the inorganic impurity that is used for handling water body is very effective, especially can dispose the filter screen in different apertures according to actual needs arbitrarily and realize different filtration needs.But the silt that present well strainer in use filters out need carry out frequent clean and influence result of use, therefore mainly be used in the cascade filtration of drip irrigation stem, and be used in combination with sandrock filter, many employing minor diameters, many group parallel connections are used, make the irrigation system complexity, increased the weight of production cost, and sandrock filter makes the entire equipment heaviness, it is very inconvenient to move.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, and volume size is little, and can realize the well strainer of automatic backwash by automaton.
The utility model comprises the filter housing body, cylindrical net formula is crossed filter core, water inlet, delivery port, backwash delivery port and backwash automaton, it is characterized in that backwash delivery port and net formula are crossed between the filter core to form between two cavitys and two cavitys is provided with dividing plate, the net formula is filtered in-core and is axially arranged with the backwash axle, this backwash axle central shaft is to being tubulose, on axis body, be provided with several backwash suction nozzles, the suction nozzle mouth is pressed close to the net formula and is filtered the in-core wall, an end of backwash axle is provided with delivery port and this water outlet end is located in the backwash water outlet oral cavity, and the backwash axle is provided with and makes backwash axle also revolvable drive unit when axially moving back and forth.
Above-mentioned net formula is crossed filter core and preferably is divided into coarse filtration net and thin two parts of screen pack, the coarse filtration net is located at inlet end, thin screen pack is located at water outlet end, and the periphery of coarse filtration net and thin screen pack separates with dividing plate, makes the net formula of filter cross two cavitys of the outer formation of filter core.
The utility model course of work is as follows: unfiltered muddy water enters cylindrical net formula by water inlet and crosses filter core, water purification after the filtration flows out from delivery port, assorted dirt on screen pack more for a long time, water-purifying cavity that the pressure test sensor of automatic backwash control device records and the hydraulic pressure pressure difference height in the muddy water chamber are regularly, central controller is that instruction control unit is opened backwash valve, start the backwash spindle motor simultaneously, the backwash axle rotates when axially moving back and forth, suction nozzle on the backwash axle siphons away the assorted dirt on the screen pack when rotating with the backwash axle, realizes automatic backwash.
Dependable performance of the present utility model, the filter of same water amount can be done to such an extent that physical dimension is less, be convenient to move, operational administrative is simple and convenient, filth-discharging effect is good, and filter need not be taken apart and filter screen can be cleaned automatically, but filter operate as normal still when cleaning filter screen, can reach the different instructions for use of user by changing different screen packs, be particularly useful in the movable filter device using and the filtration of canal river.
