Abstract
The utility model discloses a pressure difference type sensing system used for checking blocking condition of filters, comprising a filter, pressure difference sensors are arranged at water outlet end and water inlet end of the filter; the pressure difference sensors are connected with a filter blocking discrimination logic unit and the pressure difference sensors can undergo stress variation under water pressure; the filter blocking discrimination logic unit can detect whether the filter is blocked by stress signals sent out by the pressure difference sensors and output corresponding information to a control system or control unit; the design can automatically and accurately remind users to change filters and prevent the problem that water quality of different water source, water passing amount or service duration can affect judgment of users; the utility model can be widely used for central water supply filtrating system or integral pipeline drinking (purified) water machine.
Description
Technical field
The utility model relates to a kind of duct type filtering system, particularly a kind of water treatment filter pipeline system.
Background technology
In present water treatment filter pipeline system, particularly in some small-sized device systems that water purification or pure water be provided, filtrator through long-time filtration to sewage after, will change.Detecting filtrator degree method contaminated or that stop up at present has following several:
First kind: adopt by individual subjective consciousness and go to think that its quality changes, this has relatively high expectations to the user's, so be difficult to promote.
Second kind: by calculating the sum of current through filter, when reaching predetermined value, total water-flowing amount changes filtrator, but this method even flow rate calculation is accurate in the use, the different quality situation is when identical flow, it is also different with situation about stopping up that filtrator pollutes, thereby this method also is difficult to widespread use.
The third: the length by service time is changed filtrator, but this method is a general computing method, in the identical time, the source quality of various places and water flowing flow are not simultaneously, filtrator pollutes and the situation of obstruction differs greatly, thereby this method also can't accurately detect the actual operating position of filtrator.
The 4th kind: carry out photoelectric method by advanced person's equipment and instrument and detect filtrator, this method must split out filtrator, utilizes the way of the particle folded light beam that filter surfaces adheres to detect, and generally only use in the laboratory, thereby not all user can accomplish.
Thereby general manufacturer gives user prompt is after using approximately what ton water or how long using, must change filtrator, use the water quality at water source to change according to the locality again simultaneously, but how the user does not know its source quality situation, therefore, on the time of whole assurance replacing filtrator all is fuzzy concept, makes the user at a loss as to what to do.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the pressure difference method of a kind of water intake end that utilizes filtrator and water side to detect the sensor-based system of plugged filter situation.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of sensor-based system of differential detection plugged filter situation comprises filtrator, into and out of water end (W.E.) differential pressure pickup is installed at filtrator, differential pressure pickup is differentiated logical block with plugged filter and is connected, differential pressure pickup is subjected to the effect generation STRESS VARIATION of hydraulic pressure, whether the stress signal that plugged filter differentiation logical block is sent by differential pressure pickup changes the differentiation filtrator and stops up, and exports corresponding information to control system or control module; Described filtrator is for having the filtrator of pressure reduction in one or more levels water treatment filter pipeline system; Described filtrator is wire-wound filtrator, PP filtrator, block absorbent charcoal filtrator, micro-filtration filtrator, ultra filtration filter, nanofiltration filtrator, RO filtrator; Described differential pressure pickup is two pressure transducer or differential pressure transducers of being installed in filtrator into and out of water end (W.E.) respectively; It is logical circuit that described plugged filter is differentiated logical block; Described control system or control module are the display screen of control circuit driving and/or the microphone device of auditory tone cues.
The beneficial effects of the utility model are: utilize the pressure transducer be installed in filtrator water intake end and water side to test pressure differential between it, after the setting value in pressure difference value reaches plugged filter differentiation logical block, control system or control module will point out the user to change filtrator automatically and accurately, thereby not have source quality, factor affecting users such as water-flowing amount or service time judge.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of sensor-based system of differential detection plugged filter situation, comprise filtrator 1, at filtrator 1 differential pressure pickup 2 is installed, differential pressure pickup 2 is differentiated logical block 3 with plugged filter and is connected, when the input end of water from filtrator 1 enters, flow out from output terminal, when the pressure of input end is P1, when the pressure of output terminal is P2, because filtrator 1 has the choked flow effect, thereby P1＞P2, during work, its pressure reduction PV=P1-P2, progressively become big along with the accumulation of impurity screening and cause conveyance capacity progressively to weaken, after differential pressure pickup 2 detected the PV value and reaches plugged filter and differentiate setting value in the logical block 3, the conveyance capacity of expression filtrator 1 can not satisfy the requirement of operate as normal, and control system or control module 4 will point out the user to change filtrator 1 at this moment.
Differential pressure pickup 2 of the present utility model can be two pressure transducer or differential pressure transducers that are installed in filtrator into and out of water end (W.E.) respectively.And plugged filter differentiation logical block 3 is a logical circuit; its control system or control module 4 are the display screen of control circuit driving and/or the microphone device of auditory tone cues; can hold the time of changing filtrator exactly by top method user; no matter thereby use which kind of mode; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
The utility model be applied to for the filtrator that has pressure reduction in one or more levels water treatment filter pipeline system as wire-wound filtrator, PP filtrator, block absorbent charcoal filtrator, micro-filtration filtrator, ultra filtration filter, nanofiltration filtrator, RO filtrator etc., in the cascade filtration system, set reference point at different levels respectively, then every grade of filtrator get dirty or stop up after can both accurately point out replacing.
The utility model utilize pressure transducer 2 pressure differentials of filtrator front and back end and plugged filter differentiate logical block 3 built-in accurately point out the user to change filtrator with reference to pressure ratio, thereby be not subjected to the influence of water quality, water-flowing amount and service time, thereby be widely used in central water supply filtering system or fluid line drink (pure) water machine.
