The specific embodiment
Among Fig. 1 and 2, the housing 1 of full-automatic suction formula self-cleaning filter has water inlet 10 and delivery port 11, the inside of housing 1 is divided into three mutual airtight chambers by dividing plate: straining chamber 2, purge chamber 3 and blowdown chamber 4, be provided with coarse strainer 6 in the straining chamber 2, be provided with the closeer cylinder type filter net of reticulate pattern 7 in the purge chamber 3, the cavity of straining chamber 2 is provided with the pipeline (not shown), pipeline is connected the inside of coarse strainer 6 water inlet 12 by filter screen 7 with filter screen 7 inside, the filter screen 7 that closes on blowdown chamber 4 one sides is provided with floss hole 13, floss hole 13 communicates with blowdown chamber 4 by pipeline, blowdown chamber 4 is provided with sewage draining exit 16, be connected with blow-off pipe 15 on the sewage draining exit 16, blow-off pipe 15 is provided with blowoff valve 14.Mandrel 5 is positioned at housing 1, and a wherein end of mandrel 5 is in straining chamber 2, and the other end is positioned at blowdown chamber 4, and dirt sucking tube 8 is fixed on the mandrel 5, and the axis direction of the outer surface of dirt sucking tube 8 is provided with several staggered suction nozzles 9.One end of suction nozzle 9 communicates with dirt sucking tube 8, and the other end and filter screen 7 are at a distance of suitable distance, the dead in line of the axis of mandrel 5 and filter screen 7.The water inlet 10 of housing 1 enters coarse strainer 6 outsides of straining chamber 2 by pipeline, and delivery port 11 is by filter screen 7 exterior of pipeline and purge chamber 3.Outer setting at housing 1 has motor 18, be fixed with sleeve 20 on the output shaft 19 of motor 18, the outer surface of sleeve 20 is threaded, sleeve 20 is enclosed within the hold-down nut 22 that is complementary with it, output shaft 19 links to each other with mandrel 5 in the blowdown chamber 4 by shaft coupling 21, and mandrel 5 both sides are respectively arranged with two limited blocks 23 and 24.The two ends of pressure difference switch 17 are separately positioned on the people mouth of a river 10 and delivery port 11 places of housing, and link to each other with the control system (not shown), and blowoff valve 14 also links to each other with control system respectively with motor 18.
During work, pending water is entered outside the coarse strainer 6 in the straining chamber 2 by the water inlet 10 of housing 1, enter the inside of coarse strainer 6 by coarse strainer 6 through the rough water that filters, after the impurity of larger particles is filtered in the water, enter in the filter screen 7 in the purge chamber 3 by pipeline and water inlet 12, foul in the water, impurity are intercepted by filter screen 7, be trapped in the filter screen 7, and the clear water after filtering see through filter screen 7 and the delivery port 11 by filter screen 7 outsides is transported to the external world.After the foul in the filter screen 7, impurity build up to a certain degree, form the impurity screening layer,, therefore formed a pressure reduction in the inside and outside both sides of filter screen 7 because impurity layer is deposited on the inner surface of filter screen 7.The pressure at this place is monitored at the two ends that are arranged on the pressure difference switch 17 at the water inlet 10 of housing 1 and delivery port 11 places at any time, when the pressure reduction at two ends reaches the predetermined value that pressure difference switch 17 sets, pressure difference switch 17 is transferred to control system with signal, control system is sent drive motors 18 and is opened the signal of blowoff valve 14, water filtration this moment process is uninterrupted, the water purification supply continues to flow, the output shaft 19 of motor 18 drives sleeve 20 and mandrel 5 rotates, because sleeve 20 is enclosed within the hold-down nut 22, under the situation that nut 22 is fixed, output shaft 19 moves axially in rotation, the suction nozzle 9 that promptly drives the dirt sucking tube 8 on the mandrel 5 motion of spinning vertically, when dirt sucking tube 8 moved axially to certain position, the limited block 23 on the mandrel 5 stoped mandrel 5 to move axially, and motor 18 is backward rotation again, driving dirt sucking tube 8 axially moves in the other direction, after oppositely moving a certain distance, another piece limited block 24 on the mandrel 5 stops mandrel 5 to continue to move, and motor 18 changes rotation direction again.
Under the momentum effect of the water that enters filter screen 7, the foul of filter screen 7 inner surfaces, impurity enter in the dirt sucking tube 8 by suction nozzle 9, and enter blowdown chamber 4 by floss hole 13, and to discharge extraneously again from blow-off pipe 15 by sewage draining exit 16, whole cleaning process only needs tens of seconds.Because after filter screen 7 is cleaned totally, pressure difference switch 17 detected pressure differences are less, pressure difference switch 17 sends to control system with detection signal, control system is sent the signal that stops motor 18 runnings and close blowoff valve 14, and motor 18 stops operating, and blowoff valve 14 cuts out, system returns to the state of filtration, foul on filter screen 7, when impurities accumulation is a certain amount of, clean once more, go round and begin again.
Wherein, the material of housing 1 is a high-strength ductile cast iron, adopts the vacuum pressing and casting integral one-step molding.Mandrel 5 can also adopt other conventional drive unit to drive its rotation.The pressure difference switch 17 optional WFS11100AA type products of using Hai'an nest On-line Control technology Co., Ltd.When implementing pressure reduction control, also can the control of enforcement time, by filtration time being set and cleaning the filter screen time, realize the timing of filter screen 7 is cleaned, when reaching predetermined scavenging period, 18 work of control system drive motors begin the work of removing contamination; When scavenging period finished, control system was closed blowoff valve 14, and motor 18 stops operating, and the filtration state recovers in system.Pressure difference switch 17 can also substitute with two pressure sensors, one end of two pressure sensors all links to each other with control system, the other end is placed on the water inlet 10 and delivery port 11 places of housing 1 respectively, at any time detect the hydraulic pressure at two places, when the pressure reduction of two pressure sensors reaches predetermined value, control system starts the program of cleaning filter screen, and program is identical with the program of using pressure difference switch 17.
In addition, the output shaft 19 of motor 18 can be a screw mandrel, and screw mandrel passes the hard-wired hollow shaft that has internal thread, one end of screw mandrel links to each other with mandrel 5 by shaft joint 21, when motor 18 work, when screw mandrel drives mandrel 5 rotations, also drive mandrel 5 and move vertically.Also limited block can be set, and set the rotational time of motor 18 both forward and reverse directions, control mandrel 5 axially movable distances by control system.When reality is used, also can by adjusting concrete parameter, set the scavenging period and the number of times of filter screen 7 according to the water quality situation of recirculated water to be filtered.Blowoff valve 14 also can be arranged on floss hole 13 places, and water inlet 10 also can be arranged on the inside of coarse strainer 6, and the impurity of coarse filtration is retained in the coarse strainer 6, and the external pipe of the water after the coarse filtration by coarse strainer 6 is in water inlet 12 is sent into filter screen 7.When pending water quality is better, also straining chamber 2 can be set, take the mode of once filtering.
In order to raise the efficiency, can be by increasing the filter area of filter screen 7, like this, pollutant holding capability also improves simultaneously.Rotate the impurity that directly receives filter screen 7 inner surfaces owing to drive suction nozzle 9 high-speed screws by motor 18, so scavenging period is short, the blowdown water consumption is also few, the power supply energy consumption is low simultaneously, and feedwater is uninterrupted, and system has also realized intelligent control.
