Abstract
The utility model relates to a fully automatic self-cleaning filter which comprises a casing, a water inlet, a water outlet, a dirt discharging valve, a dirt discharging cavity, a dirt absorber, a coarse filter screen and a fine filter screen, wherein a dirt absorbing nozzle is arranged on the dirt absorber; a hydraulic motor is arranged in the dirt discharging cavity; a hydraulic piston is arranged outside the dirt discharging cavity; and the hydraulic piston and the hydraulic motor are arranged on the same axial line. Compared with the prior art, the fully automatic self-cleaning filter provided by the utility model has the advantages that the hydraulic motor is arranged in the dirt discharging cavity, so that the dirt absorbing nozzle on the dirt absorber can perform rotary cleaning motions along the inner surface of the fine filter screen without the aid of any external powers such as an alternating-current motor and compressed air, thereby reducing field installation and debugging works, simplifying the control and greatly improving the running reliability of equipment; and the hydraulic piston is arranged outside the dirt discharging cavity, so that the dirt absorber can be propelled axially during a switching process of pressure boosting and pressure relief by means of the pressure generated by the filter, thereby driving the dirt absorbing nozzle to perform spiral motion; thus, the self-cleaning to the inner surface of the fine filter screen of the filter is finished.
Description
Technical field
The utility model relates to a kind of Full-automatic self-cleaning filter.
Background technology
At present, existing self-cleaning filter, by water inlet, delivery port, blowoff valve, blowdown chamber, pollution-absorbing nozzle, coarse strainer, fie screen drive motors and differential pressure controller form, when work, first former water enter filter from water inlet through coarse strainer, the suspended impurity of larger particles is just tackled by coarse strainer, make it to enter fie screen, so just to fie screen and pollution-absorbing nozzle until protective effect, water after coarse strainer then enters fie screen inside, in water, more tiny suspension will be intercepted on fie screen inner surface, along with constantly gathering of suspension, between fie screen surfaces externally and internally, just produce a pressure differential, when pressure differential constantly increases, while reaching the preset value of differential pressure controller, blowoff valve is opened automatically, the pressure moving decline rapidly because of opening of blowoff valve of blowdown chamber, thereby on pollution-absorbing nozzle, produce one suction, the suspension gathering on fie screen inner surface is sucked in soil pick-up pipeline, from the course of work of above filter, we can know, fie screen can be backwashed while wanting blowoff valve to open near the part of pollution-absorbing nozzle totally, but the problem existing is, for the inner surface of whole fie screen, just cannot automatically clean up.
Summary of the invention
The purpose of this utility model is to provide a kind of Full-automatic self-cleaning filter that can automatically fie screen inner surface be cleaned up.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises housing, water inlet, delivery port, blowoff valve, blowdown chamber, dirt sucking device, coarse strainer, fie screen, described pollution-absorbing nozzle is located on dirt sucking device, its feature is: in described blowdown chamber, be provided with hydraulic motors, blowdown is provided with hydraulic piston outside chamber, described hydraulic motors is located on dirt sucking device, and described hydraulic piston and hydraulic motors are arranged on same axis; Described hydraulic piston completes the axial promotion to dirt sucking device in the process of filtration system pressurization and the switching of pressure release two states, and then drives suction nozzle to move up and down.
Compared with prior art, the utility model one is: in blowdown chamber, be provided with hydraulic motors, what make that pollution-absorbing nozzle on dirt sucking device cleans along fie screen inner surface rotatablely moves, can be by means of any external power, as: alternating current generator or compressed air etc., thereby reduced on-the-spot installation and debugging work, simplified control, equipment reliability of operation improves greatly; The 2nd: outside blowdown chamber, be provided with hydraulic piston, the pressure that can produce by filter itself, in the process that pressurization and pressure release two states switch, complete the axial promotion to dirt sucking device, and then the motion of spinning of drive pollution-absorbing nozzle, thereby the self-cleaning to filter fie screen inner surface completed.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Shown in figure: 1 is coarse strainer, 2 is fie screen, and 3 is housing, and 4 is electric controller, and 5 is dirt sucking device, and 6 is blowoff valve, and 7 is hydraulic piston, and 8 is hydraulic motors, and 9 is blowdown chamber, and 10 is delivery port, 11 pollution-absorbing nozzles, and 12 is water inlet.
Detailed description of the invention
Embodiment: with reference to accompanying drawing, the present embodiment comprises housing 3, water inlet 12, delivery port 10, blowoff valve 6, blowdown chamber 9, dirt sucking device 5, coarse strainer 1, fie screen 2, electric controller 4 and Pressure gauge, described pollution-absorbing nozzle 11 is located on dirt sucking device 5, in described blowdown chamber 9, there is no hydraulic motors 8, outside blowdown chamber 9, there is no hydraulic piston 7, hydraulic motors 8 is located on dirt sucking device 5, hydraulic piston 7 is arranged on same axis with hydraulic motors 8, hydraulic piston 7 completes the axial promotion to dirt sucking device 5 in the process of filtration system pressurization and the switching of pressure release two states, and then drive suction nozzle 11 to move up and down.First water source enters filter through coarse strainer 1, the suspension of larger particles as: slag particle, stone etc. is tackled by coarse strainer 1, makes it to enter fie screen 2, so just can play a protective role to fie screen 2 and pollution-absorbing nozzle 11.Water after coarse filtration then enters fie screen 2 inside, in water thinner suspension as: algae, iron rust, foundry loam, microorganism etc. are intercepted on fie screen 2 inner surfaces.Along with constantly gathering of suspension, between fie screen 2 surfaces externally and internallies, just produce a pressure differential, when pressure reduction constantly increases, reach preset value as: when 0.03～0.05MPa, blowoff valve 6 is opened automatically, because blowoff valve 6 opens, pressure declines rapidly in blowdown chamber 9, thereby produces one suction on pollution-absorbing nozzle 11, and the suspension gathering on fie screen 2 inner surfaces is sucked in soil pick-up pipeline.
Hydraulic motors is to utilize waterpower as motive drive unit, the turning pair that the power of hydraulic motors produces at diagonal angle in the other direction from quick current, and current only just can produce in the time of filter backwash fast.In filter apparatus, exactly because the ingenious application of hydraulic motors, what pollution-absorbing nozzle cleaned along fie screen inner surface rotatablely move can be by means of any external power as alternating current generator or compressed air, thereby reduce on-the-spot installation and debugging work, for the control system after simplifying, equipment reliability of operation will be greatly improved.
Hydraulic piston is the pressure by means of system itself, completes the axial promotion of dirt sucking device is moved, and then drive suction nozzle to move up and down in the process of pressurization and the switching of pressure release two states.
The axially-movable that rotatablely move and the hydraulic piston of hydraulic motors formation forms, finally makes suction nozzle to realize screw along the axial line of filter screen, within the time in 10 to 15 seconds, the inner surface of whole filter screen is cleaned one time automatically.
The backwash of filter screen, except pressure difference signal starts, also can start backwash procedure by timing controlled automatically, and in filter apparatus, filter has this two kinds of control models and the most basic manual anti-Shen Gongneng simultaneously.
