Description
Technical field
The utility model relates to a kind of automatic eddy flow self-cleaning type filter that farm irrigation system is filtered.
Background technology
The current automatic backwashing filter that is used for farm irrigation system generally all adopts the screen mesh type automatic backwashing filter, the final stage that the screen mesh type automatic backwashing filter generally is used to filter is filtered, reach the optimum filtration effect, its front end generally also will be by means of the previous filtration of other filters, if directly use the screen mesh type automatic backwashing filter, the impurity that particle in the sewage is bigger easily causes damage to screen cloth, reduced the service life of screen cloth, increased cost, patent ZL 200620106264.6 disclosed a kind of filters for example with backwashing function, comprise the tank body that is provided with delivery port, be arranged on tank base and have water inlet and the fangs of blow-off pipe, be arranged on the cover at tank body top, be arranged on the upper spacer and the lower clapboard at tank body two ends, be arranged on the filter core between the lower clapboard, the blow-off pipe and the drive unit that link to each other with sewage draining exit on the fangs, wherein said go up lower clapboard have mutually over against the duct, the two ends of described filter core just are docked on the corresponding duct, and the upper end of this filter core is provided with the filter core capping, and described blow-off pipe drives its rotation by described drive unit, and the one end is docked on the duct of described lower clapboard.Its deficiency is that screen cloth is difficult for being directly used in sewage filtered, and generally its front end will be by means of the filter of other type, because the fragile filter screen of the impurity that particle is bigger in the sewage, in the service life of reducing filter screen, increases the operating cost of filtration system.
Summary of the invention
It is perishable that the purpose of this utility model is to solve the filter screen that has automatic backwash screen mesh type filter, and cost improves problem.And then provide a kind of safe and reliable, cost is low and the filter that can use separately.
Its basic system of the utility model comprises that mainly the two ends of filter housings, housing base, upper press cover, housing and the centre of housing are provided with four road dividing plates, housing is divided into that the net formula is filtered and centrifugal filtration two cavitys and an excessive cavity between them up and down, in net formula filter chamber, be provided with net formula filter core arranged into a circular shape, filter core is embedded on the dividing plate at net formula filter chamber two ends, filter core one end communicates with excessive cavity, end sealing.And in the centrifugal filtration chamber, be provided with centrifugal filter device, on upper press cover, be provided with the power indexing mechanism, form one under its centrifugal filtration chamber between endplate and the housing base and little hold dirty chamber, the bottom of holding dirty chamber is provided with blow-off pipe, in the middle of filter housings, be provided with center rotation drive rod, drive rod drives the backwash suction nozzle and presses the certain angle rotation, in time net formula filter core is carried out backwash.
Centrifugal filter device has been set up in the utility model inside, centrifugal filter device directly communicates with water inlet, through the preliminary filtration of centrifugal filter device, can fall by the contaminant filter that particle in the sewage is bigger, thereby reduced the damage of large granular impurity to a great extent screen cloth.Improved the service life of filter screen, the cost when having reduced the filtration system operation can use separately, and transportation, easy for installation is used extensively.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure, 1 is motor, and 2 is indexing mechanism, and 3 is the centre-driven bar, and 4 is upper press cover, 5 is delivery port, and 6 is filter housings, and 7 is filter core, and 8 are the backwash suction nozzle, and 9 is water inlet, 10 is centrifugal filter device, and 11 is the tank body base, and 12 is centrifugal blow-off pipe, and 13 is net formula sewage backwash pipe.
The specific embodiment
Accompanying drawing has shown the structural representation of the embodiment of the automatic eddy flow self-cleaning type of the utility model filter.Wherein 6 is filter housings, four road dividing plates are arranged in the housing, 3 cavitys will be divided in the housing, be respectively net formula filter chamber from top to bottom, middle excessively chamber and centrifugal filtration chamber, on the dividing plate of net formula filter chamber upper end strut and hinge are installed, upper press cover 4 can be propped up, be convenient for changing filter core, its upper press cover is provided with the whole driving mechanism of motor and protractor composition, driving mechanism is controlled the rotation of backwash suction nozzle 8 by centre-driven bar 3, the outer wall of net formula filtration cavity is provided with delivery port 5 and communicates with it, be provided with filter core 7 arranged into a circular shape in the cavity, the filter backwash suction nozzle 8 of handstand " F " shape is installed in excessive chamber, centre, 1/3 place of recoil suction nozzle is fixed on the end of centre-driven bar, it is communicated with interior blow-off pipe with the coaxial backwash suction nozzle pipe outer wall opposite side of centre-driven bar, and its backwash suction nozzle is connected on the net formula sewage backwash pipe 13 by movable sealing sleeve, and both communicate.In the centrifugal filtration chamber, be provided with centrifugal filter device 10, the water inlet of centrifugal filter device communicates with water inlet 9, delivery port communicates with middle excessively chamber, the sewage draining exit of its centrifugal filter device communicates with the dirty chamber of holding that has centrifugal filtration chamber lower clapboard and tank body base 11 to make, and is connected with centrifugal blow-off pipe 12 in the bottom of holding dirty chamber.
Operation principle: sewage is entered in the centrifugal filter device by water inlet, contaminant filter particle in the sewage is bigger by the cyclonic action of centrifugal filter device falls, the impurity that its particle diameter is bigger is deposited in earlier and holds in the dirty chamber, delivery port through the process of the water after coarse filtration centrifugal device enters middle excessively chamber, the duct that has many one-tenth circumferential on the upper spacer in middle excessively chamber communicates with the filter core that the net formula is filtered, water have these ducts enter net formula filter core in, enter irrigation system by delivery port at last through the clear water after the filtration of net formula filter core.When the internal pressure of net formula filter chamber is too high, transmit the control section that a signal is given filter by differential manometer, the controller analytic signal, starter motor rotates, and the web-roll core to filter filters successively.The backwash of its filter and normal filtration are carried out simultaneously, the rotation of motor, rotate simultaneously by decelerator driven gear dish, toothed disc and the protractor engagement that becomes spline shape, stop by the identical angle of the each rotation of protractor by travel switch, the angular turn of deciding of index dial is passed through the rotation that the centre-driven bar drives the backwash suction nozzle, make the backwash suction nozzle can block the water inlet of three different net formula filter cores successively with the regular hour, water inlet is blocked after death, the filtration of other filter core is normally carried out, like this, the clear water that other filter core filters will carry out backwash with the filter core that water inlet is blocked in the other direction, and the impurity of flushing has net formula blow-off pipe to discharge at last.
