Description

A kind of anti-filter rinsed
Technical field
The present invention relates to filter technology field, particularly relate to a kind of anti-filter rinsed.
Background technology
Existing light water filter does not possess backwashing function, and after filtering work a period of time, the particle in water sticks on filter screen, needs to quit work, and could clean filter screen or change, the work continuity of influential system and benefit.
Occurred a kind of fully automatic cleaning filter in the market, but the pollutant holding capability of this filter is little, is subject to dirt blocking, filtration fraction needs to carry out dismantling and cannot monitor filter state.
Summary of the invention
The present invention, in order to overcome deficiency of the prior art, provides a kind of anti-filter rinsed.
The present invention is achieved through the following technical solutions:
A kind of anti-filter rinsed, comprise filter body cylindrically, the lower end of described filter body is provided with mount pad, the upper end of filter body is provided with power motor, coarse filtration net and thin screen pack is provided with in described filter body, and described coarse filtration net is arranged on the downside of filter body, thin screen pack is arranged on the upside of filter body, portable plate is provided with between coarse filtration net and thin screen pack, described portable plate is arranged on the inwall of filter body, in the upside of thin screen pack, fixed head is installed, dwang has been passed in fixed head, described dwang is by power motor driven rotary, a row brush hair is provided with in that section of dwang outside wall surface both sides putting in thin screen pack, bristle can clean the inwall of thin screen pack under the effect of dwang, impurity after cleaning discharges through blowoff valve, described air bleeding valve is arranged in the outside wall surface of filter body, described filter body is provided with differential pressure transmitter be connected with controller, described controller controls the keying of power motor.
As the preferred technical solution of the present invention, the side of described filter body is provided with water inlet pipe and outlet pipe, and described water inlet pipe and outlet pipe are arranged on the same side of filter body, and water inlet pipe is positioned at the below of outlet pipe.
As the preferred technical solution of the present invention, described blowoff valve and outlet pipe are arranged on the not homonymy of filter body, and described differential pressure transmitter is arranged on the same side of blowoff valve.
Compared with prior art, the invention has the beneficial effects as follows: this filter can identify the deposition degree of impurity automatically, dwang is driven to do axially-movable and screw by power motor, thus the inwall of bristle to thin screen pack on drive dwang cleans, impurity is discharged from blowoff valve, can automatic backwash be realized, and washing time is short, operating efficiency is high, and strainability is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1-filter body; 2-mount pad; 3-water inlet pipe; 4-outlet pipe; 5-power motor; 6-coarse filtration net; The thin screen pack of 7-; 8-portable plate; 9-fixed head; 10-dwang; 11-bristle; 12-shaft coupling; 13-sleeve; 14-blowoff valve; 15-differential pressure transmitter; 16-controller.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is structural representation of the present invention.
The anti-filter rinsed of described one, comprise filter body 1 cylindrically, the lower end of described filter body 1 is provided with mount pad 2, the upper end of filter body 1 is provided with power motor 5, and the side of described filter body 1 is provided with water inlet pipe 3 and outlet pipe 4, and described water inlet pipe 3 and outlet pipe 4 are arranged on the same side of filter body 1, water inlet pipe 3 is positioned at the below of outlet pipe 4, when filtering, intake by water inlet pipe 3, outlet pipe 4 water outlet.
Coarse filtration net 6 and thin screen pack 7 is provided with in described filter body 1, and described coarse filtration net 6 is arranged on the downside of filter body 1, thin screen pack 7 is arranged on the upside of filter body 1, portable plate 8 is provided with between coarse filtration net 6 and thin screen pack 7, described portable plate 8 is arranged on the inwall of filter body 1, in the upside of thin screen pack 7, fixed head 9 is installed, dwang 10 has been passed in fixed head 9, dwang 10 is connected with power motor 5 through filter body 1, and dwang 10 is connected by the output shaft of shaft coupling 12 with power motor 5, thus realize power motor 5 and drive dwang 10 to rotate, outer wall through that fragment position of filter body 1 of dwang 10 is provided with the sleeve 13 of protection.
A row brush hair 11 is provided with in that section of dwang 10 outside wall surface both sides putting in thin screen pack 7, bristle 11 can clean the inwall of thin screen pack 7 under the effect of dwang 10, impurity after cleaning discharges through blowoff valve 14, described air bleeding valve 14 is arranged in the outside wall surface of filter body 1, described filter body 1 is provided with differential pressure transmitter 15 be connected with controller 16, described controller 16 controls the keying of power motor 5.
The operation principle of this filter is: when filtration work starts, water to be filtered is entered by water inlet pipe, first the impurity of larger particles is fallen through coarse filtration net filtration, then thin screen pack is arrived, in filter process, thin screen pack builds up booty in water and impurity, form impurity screening layer, because impurity screening layer is deposited in the inner side of thin screen pack, along with the impurity be retained down gets more and more, the thickness of impurity screening layer is more and more thicker, the rate of filtration will be more and more slower, therefore in thin screen pack, outer both sides just define a pressure reduction, when this pressure reduction reaches preset value, automatic cleaning process is carried out by starting, the signal of telecommunication is sent to controller by differential pressure transmitter, controller starts power motor by control system and drives dwang to rotate, dwang does axially-movable and rotary motion, blowoff valve is opened simultaneously, owing to being provided with bristle on dwang, bristle can clean the inwall of thin screen pack, impurity can be discharged by blowoff valve.After thin screen pack cleaning, pressure reduction drops to minimum of a value, and whole flushing process only needs several tens of seconds, and blowoff valve cuts out at the end of cleaning, and filter starts to prepare next flushing cycle.
As a preferred embodiment of the present invention: coarse filtration net 6 and thin screen pack 7 all adopt stainless steel material to make, and prevent in long use procedure, coarse filtration net 6 and thin screen pack 7 get rusty and cause damaging, and can improve its service life.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
