Accompanying drawing explanation
Figure 1 shows that self-cleaning filter structural representation of the present utility model;
Figure 2 shows that the structural representation of afforestation level pressure spray system of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, self-cleaning filter of the present utility model is comprised and to be fixedly connected with by outward flange and the upper tank body 1 that separates of the dividing plate about 3 that center is provided with through hole and lower tank 2, water inlet 21 is provided with bottom described lower tank, sidewall is provided with delivery port 22, inside and the described lower tank inwall compartment of terrain of described lower tank are provided with cylindrical filter sieve 23, wiper mechanism is provided with in the middle part of described screen pack, described wiper mechanism comprises the suction nozzle 5 that top is communicated with multiple with described collecting pipe through described through hole collecting pipe moving up and down 4.
Described upper tank body top is provided with hydraulic mechanism, sidepiece is provided with blow-off pipe 11, the hydraulic motors be fixedly connected with described collecting pipe top is provided with at described upper tank body internal fixtion, described hydraulic mechanism comprises the hydraulic cavities 12 being arranged on upper tank body top center, hydraulic cavities that can be relatively described is moved up and down and the piston be fixedly connected with by connecting rod 13 with described hydraulic motors, the top of described hydraulic cavities is communicated with upper tank body inside through hydraulic tube 18, described upper tank body is also provided with microstrainer 14 to suck or to discharge air.
Specifically, described hydraulic motors is cuboid box body, described box body two ends phase heteropleural offers hole for water spraying respectively, water conservancy revolution can be driven like this when the water in collecting pipe enters box body and spray in hole for water spraying, then drive collecting pipe and suction nozzle to rotate, realize the self-cleaning to screen pack inside.
Wherein, for promoting installability, be convenient to installation and removal and safeguard, described screen pack upper end is formed with fixed edge, and described fixed edge is gripped by the flange of dividing plate and lower tank.
First impurities in water is retained through screen pack, essence screen surface forms impurity screening layer gradually, inside impurities accumulation filter screen, inside and outside differential pressure forms pressure difference, when pressure difference is to 1 kilogram that sets, automatic cleaning function starts, valve open on blow-off pipe, the water of upper tank body inside flows out from blow-off pipe, simultaneously, because the water of hydraulic cavities upper piston area is also discharged thereupon, hydraulic pressure difference between upper tank body and lower tank forces water to enter box body in collecting pipe and sprays from the hole for water spraying at box body two ends, collecting pipe rotation simultaneously in the process risen realizes the comprehensive cleaning in screen pack, when collecting pipe rises to upper limit position, blow-off pipe cuts out, the pressure of upper tank body inside progressively rises, piston pressurized in plunger shaft moves downward and collecting pipe is moved down reset and enters normal filtration condition, adopt hydraulic piston as reset power, the high unity of blowdown and cleaning action can be realized, integral device stability is high and operating cost is low.
Fig. 2 disclose a kind of adopt a kind of afforestation level pressure spray system of above-mentioned self-cleaning filter to comprise to be arranged on the deep water pump 7 bottom cistern 6, with the self-cleaning filter described in described deep water pump delivery port is communicated with through outlet pipe, with described self-cleaning filter delivery port and the bellows Constant pressure tank 8 connect and variable frequency pump 9, the delivery port of described variable frequency pump is communicated with spray pipeline.Wherein, described deep water pump is by Frequency Converter Control, and described frequency converter is connected with described bellows Constant pressure tank communication.
Bellows Constant pressure tank comprises housing and Pressure gauge and internal airbag.Pending water is squeezed into self-cleaning filter import by deep well pump and is filtered, and supplies water during backwash and do not interrupt, and blowoff valve is opened and discharged by blow-off pipe by sewage, and the water a-road-through after purified treatment is to bellows Constant pressure tank, and a-road-through is to spray equipment.Time if normal spray opened by spray equipment bellows Constant pressure tank pressure gradually decline deep well pump become normal water supply duty by sleep gradually by Frequency Converter Control.When closing spray system, when bellows Constant pressure tank and pipeline pressure value rise to setting value, deep well pump enters sleep state.Wait for that unlatching next time spray equipment wakes water pump up.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
