Description
Technical field
The present invention relates to water correction plant, especially the flushing field of filter element in cleaning equipment..
Background technology
Human diseases 80% is relevant with water, and the main sterilization method of tap water is chlorination sterilization, although can remove a large amount of thin
Bacterium, but there is also harmful substance, the especially heavy metal in water, composition, course of conveying and the water such as chlorine molecule and nitrite
Tower storage etc. all can cause a certain degree of secondary pollution, although by water boil, the heavy metal etc. also cannot removed in water is harmful to
Material, the Excess free enthalpy of these materials, human body can be caused harm greatly, threaten the healthy of the mankind, town and country are from the beginning
The part of water exceeds standard, and does not reaches People's Republic of China's " drinking water sanitary standard ", and the present situation of above-mentioned pollution constitutes
Great threat to town and country personnel health.
Existing water purifier product design structure is relatively simple, generally arranges one or more filter element, filters, filter
After core uses a period of time, its filter capacity declines, and filtering water does not reaches standard, and the process to filter element is generally carried out more
Change.This can bring two problems, and filter element is using a period of time, and especially with the later stage, water quality is poor；Filter element replacing, cost
Higher, existing filter element use cost is often higher than the water directly bought through industrial filter process or bottled water etc..And current,
Backwash to filter element designs, and often structure is complicated, and general employing tap water rinses, and punching does not washes clean, and brings new pollution, punching
Wash the feature tended not to according to water route to carry out, i.e. carry out according to the opposite direction in water purification water route.
Summary of the invention
The purpose of the present invention aims to provide a kind of simple in construction, uses ultrafiltration water to carry out backwash, and fully according to only
The opposite direction in water water route is carried out, and targetedly filter element is carried out backwash, can more effectively wash away residuals, extends filter element
Life-span.
Concrete technical scheme is as follows
A kind of backwash ultra-filtration water purifier, including raw water inlet, by preposition activated charcoal filter element, the PP of the setting of water purification order
Cotton filter core, controlling the water circulation ultra-filtration element, post active carbon filter element, water purification mouth；Between described preposition activated charcoal filter element and raw water inlet
Arranging the first switch, described post active carbon filter element connects water purification mouth；It is characterized in that: also include rinsing ultra-filtration element, waste water
Mouthful, described flushing ultra-filtration element connects described controlling the water circulation ultra-filtration element, and the connection of the described flushing ultra-filtration element other end is flushed into water pipe
Road also arranges second switch, and described waste water mouth connects described preposition activated charcoal filter element by the 3rd switch.
Further, described first switch, second switch and the 3rd switch are ball valve.
Further, described first switch is normally open solenoid valve, and described second switch and the 3rd switch are normally closed solenoid valve.
Further, described normally open solenoid valve and normally closed solenoid valve are controlled in wireless.
Further, described normally open solenoid valve and normally closed solenoid valve are set to a key control, and i.e. one key control is closed normally opened
Electromagnetic valve also opens two normally closed solenoid valves simultaneously.
Further, backwash operation, use touch computer plate button, one-touch realize backwashing function.
Further, also include being flushed into the mouth of a river, connect described second switch.
Further, it is flushed into waterpipe described in and is directly connected to described raw water inlet.
Further, the controlling the water circulation process of described backwash ultra-filtration water purifier is: tap water enters from raw water inlet, opens
First switch, cuts out second switch and the 3rd switch, and tap water sequentially enters described preposition activated charcoal filter element, PP cotton filter core, system
Water ultra-filtration element, post active carbon filter element, water can be purified after opening described water purification mouth；Described backwash ultra-filtration water purifier
Backwash process be: tap water enter described in be flushed into waterpipe, open second switch, close described first switch and water purification
Mouthful, tap water sequentially enters described flushing ultra-filtration element, controlling the water circulation ultra-filtration element, PP cotton filter core, preposition activated charcoal filter element, opens institute
State the 3rd switch, discharge waste water.
The technology of the present invention effect:
The present invention is by arranging flushing ultra-filtration element so that the water of backwash is ultrafiltration water, it is to avoid recontamination；Simultaneously
The water route of backwash is contrary with the water route of water purification, i.e. ultrafiltration water presses controlling the water circulation ultra-filtration element, PP cotton filter core, preposition activated charcoal filter element
Order is carried out, and is then discharged out waste water, when to tap water water purification, is usually and sets step by step by the size of the impure granule of tap water
Putting, one-level is less than the granule of single filter, the design in this backwash water route, carries out reverse design, energy according to water purification water route feature
More effectively wash away residuals, extend filter element life；This flushing ultra-filtration element is connected with controlling the water circulation ultra-filtration element rather than with rear
Put active carbon filter core to connect, it practice, post active carbon filter element is the further absorption to the impurities in water after super-filtration purifying, as
Fruit is the most little to its effect of its backwash, so, the present invention is to have taken into full account the feature design backwash water route of filter element；Enter one
Walk and rinse ultra-filtration element and waste water mouth by arranging three switches and, can be achieved with backwash, simple in construction, effectively, and energy
Existing purifier is transformed；Although this water purifier increases by a backwash ultra-filtration element, but by appropriate design, significantly
Extend water purification catridge, the results showed, the filter element cost of whole water purifier is substantially reduced.
Switch designs is ball valve by the present invention, has actually carried out Non-follow control design, cost-effective, simplifies design；
And backwash is not required to carry out everyday, Non-follow control also can fully meet the needs of backwash.
And be electromagnetic valve by switch designs, be in order to better meet easy to use, need efficiently, by electromagnetic valve
Design realizes auto-control Design；Use further the switch of a key control backwash, and use controlled in wireless, be all for
Meet the demand of the modern life, simplify operation, convenient use.
This water purifier can be arranged and be flushed into the mouth of a river according to actual needs, and the most a total of two tap water water inlets are formed
Respective water route；One tap water water inlet also can be only set, rinse ultra-filtration element and be connected with water inlet by pipeline.
By this backwash ultra-filtration water purifier, ultrafiltration water can be used to carry out backwash, and for the feature of filter element, use with
The antipodal backwash water route, water route of water purification, to ultrafilter membrane, PP is cotton, and three grades of filter elements of preposition charcoal are rinsed, can be more effectively
Wash away residuals, extend filter element life.
