Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the invention is further described.
The present embodiment is taking filter filtered water as example.As shown in Figure 1, the present invention includes cylindrical shell 1, filter screen, filter screen comprises Inner filter net 2 and outer leaching net 3 bilayers, be arranged in parallel with cylindrical shell 1, in cleaning appliance 6 is arranged on, between outer double-layer leaching net, on cylindrical shell 1, be provided with inlet 4, liquid outlet 5 and sewage draining exit 16, enter, liquid outlet and sewage draining exit have respectively into/fluid pipeline 7 and blow-off line 14, described cylindrical shell middle part is vertically installed with pipe blow-through 8, described pipe blow-through 8 lower ends are connected with enter/fluid pipeline 7 and blow-off line 14 by control valve 13, pipe blow-through 8 upper ends are provided with hydraulic rotary device 9, by several, the aquaporin 10 of crossing by certain angle of inclination forms described hydraulic rotary device 9, hydraulic rotary device 9 top closure.Meanwhile, liquid inlet and outlet of the present invention has pressure monitor outward, because the Impurity deposition in water is on filter screen, produces pressure reduction.Change by pressure reduction monitor monitors liquid in-out mouth pressure reduction, in the time that pressure reduction reaches setting value, can start cleaning filter action by manual unlocking control valve 13, or send motor signal by pressure reduction monitor to clean controller 15, drive motors is opened pneumatic control valve, starts cleaning action.
And, as shown in Figure 1, when filter is during in filtration condition, control valve 13 moves, open into/fluid pipeline 7, closed pipe blow-through 8, water enters cylindrical shell 1 by enter/fluid pipeline 7, through the effect of inside and outside double-layer leaching net, the impurity in water is adsorbed by filter screen, and the water after filtering flows out through liquid outlet 8 again, because having the material less than water density, makes cleaning apparatus 6, so during in filtration condition, cleaning apparatus 6 floats on the upper end of double-layer filtering net, and filter process is not affected at filter.
As shown in Figure 2, because the Impurity deposition in water is on filter screen, produce pressure reduction, change by pressure reduction monitor monitors liquid in-out mouth pressure reduction, in the time that pressure reduction reaches setting value, filter starts cleaning state.The setting value of pressure reduction can be set by staff in the time of erection unit, specifically presses and determines according to the turnover of institute's filter liquide.In the time that pressure reduction reaches setting value, pressure reduction monitor sends motor signal to clean controller 15, drive motors is opened pneumatic control valve, open pipe blow-through 8 and blow-off line 14, because the caliber of pipe blow-through 14 is than little many of the caliber of enter/fluid pipeline 7, therefore, extraneous current can arrive the hydraulic rotary device 9 at pipeline top moment through pipe blow-through 14, via several have certain angle of inclination cross aquaporin 10, water flows out from crossing aquaporin 10, owing to crossing the angle of inclination of aquaporin, when rinse water is spouting, form the eddy current of spiral rotating in the periphery of pipe blow-through, under certain pressure-acting, the flow rate of water flow of water is very fast, washing away cleaning appliance 6 rotates with current, from top to bottom, brute force is washed away the surface of filter screen 2 and 3, reach the object of cleaning filter screen, and addle is passed through the discharge cylindrical shell 1 of blow-off line 14 after cleaning, cleaning appliance 6 is got back to home position, again wash away screen surface, play the effect of the clean filter screen of secondary.
Blow-off line 14 of the present invention has adopted siphon vortex device 12, with respect to plain filter, hydraulic rotary device 9 of the present invention and siphon vortex device 12 are used in conjunction with, due to the effect of siphon vortex device, the eddy current flow of siphon eddy current is to consistent with the spiral rotating direction of hydraulic rotary device, the spiral vortex of the swirl ratio hydraulic rotary device of siphon eddy current is relatively large, can make in filter cylinder temporary transient in negative pressure state, not only make the discharge cylindrical shell that sewage can be very fast, and, can make the clear water partial reflux in cylinder, flush clean filter screen, play the effect of dual cleaning.
Meanwhile, the present invention has also designed manual cleaning device, by rotary manual valve manually, manual operation can be according to the needs of actual cleaning strength, the openings of sizes of control valve, the current that make to enter pipe blow-through are large and small controlled, thereby change rinse water scouring intensity.
According to real work needs, as shown in Figure 2, cylindrical shell of the present invention upper end is also provided with source of the gas and washes away servicing unit 11, when on the filter screen that need clean, impurity is many, intake pressure is smaller or have very strong tack be difficult to wash away clean in the situation that under common pressure, can open source of the gas and wash away servicing unit, under suppressing by force, brute force is washed away screen surface, reaches cleaning object.
Device of the present invention, can be used in conjunction with intelligent device.In other words, according to principle of the present invention, can be in installation apparatus of the present invention, character (its density, the viscosity of the liquid filtering as required, impure amount etc.), at intelligent terminal, data are set in advance, when in filter work, the signal of feedback reaches in intelligent terminal, intelligent terminal sends filtration/purge signal, realizes automated job.
More than the explanation of preferred embodiment of the present invention, according to the principle of the embodiment of the present invention and method, the part that all changes in detailed description of the invention, therefore, this description not should be understood to the restriction to this explanation.
