Description
Technical field
The utility model relates to a kind of full-automatic self-cleaning filter that is used for drip irrigation.
Background technology
Because the feedback of water resource is general, the scope that technology such as drip irrigation and spray irrigation are used more and more widely is applicable to that the drip irrigation and spray irrigation equipment of various agriculture requirements also is developed thereupon, and its middle filtrator is a nucleus equipment.Use at present more be net formula, centrifugal, sandstone formula or laminated filter.
Well strainer can dispose the filter screen in different apertures according to actual needs arbitrarily and realize different filtration requirements, and simple in structure, low cost of manufacture, but the silt that well strainer in use filters out need carry out frequent clean and influence result of use.
Summary of the invention
It is a kind of simple and practical that the purpose of this utility model is to provide, and can realize full-automatic self-cleaning filter by automaton.
The utility model comprises filter housing, cylindrical net formula is crossed filter core, water inlet, delivery port, soil chamber, sewage outlet and cleaning automaton, it is characterized in that soil chamber and cylindrical net formula crossed and be divided into two cavitys between the filter core, cylindrical net formula is filtered in-core and is axially arranged with the self-cleaning axle, this self-cleaning axle central shaft is to being tubulose, on axis body, be provided with several and clean suction nozzle, the suction nozzle mouth is pressed close to the net formula and is filtered the in-core wall, one end of self-cleaning axle is provided with sewage outlet and this delivery port is located in the soil chamber, on the self-cleaning axle, be provided with the drive unit hydraulic motor that can make the rotation of self-cleaning axle, and the drive unit hydraulic piston that the self-cleaning axle is axially moved back and forth.
Above-mentioned net formula is crossed filter core and preferably is divided into coarse filtration net and thin screen pack two parts, and the coarse filtration net is located at inlet end shape for covering shape, and it is cylindrical that thin screen pack is located at water outlet end, and coarse filtration net and thin screen pack have two independently cavitys of one's own.
The utility model course of work: the muddy water that is used for irrigating enters filter by water inlet, enter cylindrical net formula after filtering by the coarse filtration net earlier and carefully filter in-core portion, arrive the web-roll core outside by filter screen, water purification after the filtration flows out from delivery port, impurity is blocked in filter core inside in the water, when impurity more for a long time in the web-roll core, the outer pressure reduction that forms, when pressure reduction reaches the differential pressure controller setting value, the self-cleaning process will begin automatically, magnetic valve is opened blowoff valve, hydraulic motor and hydraulic piston drive rotation of self-cleaning axle and axially-movable, be located at several that establish on the axis body and please wash suction nozzle the dirt on whole web-roll core surface is inhaled down, and discharge from soil chamber and sewage outlet with sewage.
Dependable performance of the present utility model, operational administrative is simple and convenient, filth-discharging effect is good, be convenient to move, filter need not be taken apart and filter screen can be cleaned automatically, but filter operate as normal still can reach the different instructions for use of user by changing different screen packs when cleaning filter screen, is particularly useful for using in the movable filter device and to the filtration of canal river.
