Description

The large flow self-cleaning net type filter of micro-head
Technical field
The utility model belongs to the improvement, the particularly large flow self-cleaning net type filter of a kind of micro-head of water filtering device for water-saving irrigation.
Background technology
Xinjiang is typical arid oasis irrigated agricultural area, and building Water-saving Agriculture is the key of agricultural sustainable development.7,500 ten thousand mu of Xinjiang cultivated areas, end built approximately 3,000 ten thousand mu of the high-efficiency water-saving areas of establishing in 2011, mainly adopt underground water pressurization drip irrigation technique.According to Xinjiang " 12 " waterpower development plan, full boundary also will increase 3,000,000 mu of efficient water-saving irrigation areas every year newly.Along with the expansion of water saving area, to the disposal ability of drip irrigation header filter with require also just highlyer, according to power form drip irrigation header filter, be divided into self-pressure self-cleaning and electric drive is cleaned two kinds.According to the form of filter, be divided into well strainer, medium filter, the large kind of laminated filter three, wherein well strainer is most widely used.
Present self-cleaning net type filter used is divided into self-pressure cleaning and electric drive is cleaned.It is not want external impetus that self-pressure is cleaned advantage, but must need certain hydraulic pressure to realize.And electric drive cleaning pluses and minuses are just in time cleaned contrary with pressure.
Utility model content
The purpose of this utility model is to provide a kind of micro-head large flow self-cleaning net type filter, can realize filter cleans automatically, do not need to be equipped with special messenger, during cleaning, only need the water yield and very low hydraulic pressure seldom, scavenging period is short, filter efficiency is high, and does not affect the normal work of system while cleaning.
The purpose of this utility model is achieved in that the large flow self-cleaning net type filter of a kind of micro-head, comprise the vertical tank body with water inlet and delivery port, bottom is arranging diaphragm plate within it, by upper bearing (metal) and the cooperation of the lower bearing on diaphragm plate arranging on vertical tank body upper cover, the blow-off pipe that upper end has rotating shaft is installed, the reducing motor of installing by bearing drives the blow-off pipe rotating shaft that passes vertical tank body upper cover, the screw rod arranging at rotating shaft middle part matches with the hold-down nut arranging on bearing, guiding key way in rotating shaft matches with the drag chain of reducing motor rotor bore, the contact disc that rotating shaft upper end arranges matches with stopping means, the conical filter screen that suitable for reading and vertical inner tank wall matches is installed on diaphragm plate, on blow-off pipe, the pollution-absorbing nozzle of uniform setting matches with conical filter screen respectively, the blow-off pipe stretching out from diaphragm plate below is positioned at decontamination chamber, on the discharge pipe of decontamination chamber that stretches out vertical tank body, electromagnetism blowoff valve is installed.
The utility model is installed with conical accurate filter screen in tank body, in accurate filter screen, the blowdown hollow pipe of chewing with some soil pick-ups is installed, after the bright and clean drive bearing of mounting surface above blowdown hollow pipe seals by sealing ring, stretching out filter outside, is that screw mandrel upper end is that the bearing of keyway is connected with lower end.Screw mandrel coordinates with the nut being fixed on pedestal, and keyway coordinates with the reductor being connected on motor, and reductor top is connected positioning disk with keyway end, and positioning disk moves between upper limit and lower limit.At water inlet tank body and water outlet tank interior, pressure sensor probe and differential pressure pickup probe are housed respectively.The large flow self-cleaning net type filter of the micro-head of the utility model, adopt conical filter screen, when current pass through filter screen, the centrifugal force being produced by filter screen and the self gravitation of sand grain, and the filter screen being formed by 3 layers of stainless steel, three kinds of comprehensive sediment trappings of sediment trapping mode, good filtration effect compared with traditional circle tube leaching net is a lot, and water for cleaning amount is few, lower than the operating pressure of import equipment, scavenging period is short, does not affect the normal work of system during cleaning.
Operation principle of the present utility model is: the water after sedimentation basin primary filter enters conical filter screen from water inlet, when the impurity of larger particles will flow through conical filter screen, the power that can be centrifuged throws away, along screen surface, be slipped to sand export because of self gravitation, guarantee to stay granule impurity on conical screen and can not stop up soil pick-up and chew.Now clean water is discharged from delivery port after strainer filtering.When a stage of filter work or enter water quality in filter chamber when poor, on conical screen inwall, adhere to dirt when more, the discharge reduction filtering through conical screen, make in conical screen, when exocoel produces certain pressure reduction, differential pressure pickup starts, and drive reducing motor and magnetic valve to work by controller simultaneously, reducing motor drives hollow shaft to rotate by power transmission shaft, pollution-absorbing nozzle in hollow shaft on uniform dirt sucking tube sucks the dirt on filter screen in pressing close to conical screen rotation process, under the effect of hydraulic pressure, the water of carrying dirt secretly is entered to hollow shaft, by hollow pipe, through magnetic valve, discharge.Reducing motor is in the process that drives power transmission shaft to rotate, power transmission shaft spiro rod section matches with the hold-down nut on supporting seat, power transmission shaft is promoted forward, the guide key groove section of power transmission shaft is under the constraint of the feather key of reducing motor rotor bore, in transmission, to front slide, the rotation limit, soil pick-up mouth of hollow dirt sucking tube is moved forward; When the contact disc of the power transmission shaft moving forward in transmission is encountered the stop on reducing motor, controller is controlled reducing motor reversion, on supporting seat, hold-down nut makes power transmission shaft drive hollow shaft to fall back, when the contact disc on the power transmission shaft falling back is encountered the stop of reducing motor downside, reducing motor forward, automatic reciprocating periodic duty.When the dirt on conical screen exhausts, when the pressure reduction in inside and outside chamber is tending towards close or equal, now reducing motor quits work.The utility model cleans working time and the intermittent time of filter screen and can set arbitrarily by controller panel.It is high that the utility model is realized automatic cleaning strainer automaticity, do not need to be equipped with special messenger, only needs the water yield seldom and lower hydraulic pressure during cleaning, and scavenging period is short, and do not affect the normal work of system while cleaning.Filter is uninterrupted normal water supply when cleaning, and the self-cleaning time only needs 20-40 seconds, on not impact of normal water supply.The method of controlling can be diversification; electric-control board can meet various requirement: controlled pressure reduction or time clean, also can continuous wash, and can also be when pressure be elevated to dangerous pressure suddenly; filter blowoff valve can be opened pressure release, the safety of protection system automatically.
The utility model has been realized self-washing of filter, does not need to be equipped with special messenger, only needs the water yield and very low hydraulic pressure seldom during cleaning, and scavenging period is short, has improved filter efficiency, and does not affect the normal work of system while cleaning.
