Description

A kind of counter-infiltration system

Technical field

This utility model is related to water treatment field, specifically a kind of counter-infiltration system.

Background technology

Existing reverse osmosis water purifier typically carries out pretreatment using PP cotton, activated carbon or ceramic-like product to tap water. Due to the float in tap water, granule and other debris in filter process, very quickly will be in PP cotton, activated carbon or pottery The cartridge surface of porcelain class forms deposition, hinders the entrance of tap water, leads to subsequent pressurization pump hydropenia to cause electrical component to damage Or the little not even water outlet of purified water storage amount.The filter element PP cotton of therefore general producer all prompting pretreatment repeatedly needs 3 months Change once, activated carbon needs June to change once, frequently change filter element to ensure effective operation of whole machine.But in this process In, need specialty personnel after sale to be safeguarded due to changing filter element, one is that cost is higher, it is big to waste, and directly resulting in user makes With cost increase, two is to change not in time, easily causes machine breakdown, brings bigger impact to user.

Utility model content

The purpose of this utility model is costly and inefficient to solve anti-penetration water purifier water purification in prior art Defect, provides a kind of counter-infiltration system to solve the above problems.

To achieve these goals, the technical solution of the utility model is as follows：

A kind of counter-infiltration system, including pretreatment unit, reverse osmosis unit and pure water tank, described pretreatment unit, reverse osmosis Device and pure water tank are sequentially communicated thoroughly, and described pretreatment unit includes raw water inlet, pretreatment outlet and pretreatment chamber, institute State upper end lateral wall when raw water inlet is located at pretreatment, described pretreatment outlet is located at pretreatment chamber's lower end outside wall, institute State central authorities of pretreatment chamber setting ceramic element, ceramic element periphery setting one encloses drainage screen, along described ceramic element axially uniformly It is distributed several grooves, described pretreatment unit also includes rotating shaft, and described rotating shaft runs through ceramic element and extends to pretreatment unit Outside top, described rotating shaft is connected with motor, and described reverse osmosis unit includes reverse osmosiss water inlet, reverse osmosis membrane, pure water go out Mouthful and wastewater outlet, reverse osmosis unit divided into filtering area and clean water area by described reverse osmosis membrane, described filtering area one end with anti- Infiltration water inlet is connected, and the described filtering area other end is connected with wastewater outlet, and described clean water area is communicated with pure water outlet.

Preferably, described pretreatment unit bottom also sets up dirty row's mouth, and described sewage draining exit is located at below described ceramic element.

Preferably, the cross section of described groove is semicircle.

Preferably, booster pump is installed between described pretreatment unit and reverse osmosis unit.

Preferably, also set up flow control valve between described pretreatment unit and described booster pump.

Compared with prior art, the beneficial effects of the utility model are：1）Setting rotating shaft in pretreatment unit, accelerates to filter Speed, put forward filter efficiency；2）Ceramic element side wall setting groove, increased the contact area of water and filter element, filter effect is more Good；3）Pure water and waste water can quickly be distinguished by the filtration of reverse osmosis membrane, improve filter efficiency.

Specific embodiment

Effect for making to architectural feature of the present utility model and reached has a better understanding and awareness, in order to relatively Good embodiment and accompanying drawing cooperation detailed description, are described as follows：

A kind of counter-infiltration system, including pretreatment unit, reverse osmosis unit and pure water tank 15, described pretreatment unit, anti- Permeability apparatus and pure water tank 15 are sequentially communicated, and described pretreatment unit includes raw water inlet 1, pretreatment outlet 2 and pre- place Reason room 3, upper end lateral wall when described raw water inlet 1 is located at pretreatment, described pretreatment outlet 2 is located under pretreatment chamber 3 End lateral wall, described pretreatment chamber 3 central authorities' setting ceramic element 4, ceramic element 4 periphery setting one circle drainage screen 5, along described pottery Porcelain filter element 4 is axially uniformly distributed several grooves 6, and described pretreatment unit also includes rotating shaft 7, and described rotating shaft 7 runs through ceramic element 4 And extending to outside pretreatment unit top, described rotating shaft 7 is connected with motor 8, and described reverse osmosis unit includes reverse osmosis and penetrates The mouth of a river 9, reverse osmosis membrane 10, pure water outlet 11 and wastewater outlet 12, reverse osmosis unit is divided into filtration by described reverse osmosis membrane 10 Area 13 and clean water area 14, described filtering area 13 one end is connected with reverse osmosiss water inlet 9, and described filtering area 13 other end is gone out with waste water Mouth 12 is connected, and described clean water area 14 is communicated with pure water outlet 11.

Pretreatment unit bottom opens up sewage draining exit 16, and the impurity such as bulky grain in raw water, Organic substance is removed, can be by row Dirty mouth 16 is discharged, and sewage also can be discharged from sewage draining exit 16 simultaneously.

Ceramic element 4 surface setting cross section is semicircular groove 6, compared to cylindrical filter element, increases pottery The surface area of filter element 4, thus increase the contact area of water and ceramic element 4；Meanwhile, rotating shaft 7 turns under motor 8 drive Dynamic, ceramic element 4 also concomitant rotation, improve the filter efficiency of ceramic element 4；When rotating shaft 7 inverts, in the effect of groove 6 Under can carry out backwash to drainage screen 5, thus play cleaning drainage screen 5 effect.
