[specific embodiment]

It is further described below in conjunction with the attached drawing structure convenient for filter core installing and dismounting a kind of to the utility model:

For the ease of understanding the utility model, in the following with reference to the drawings and specific embodiments, the utility model is carried out more detailed Thin explanation.

As shown, a kind of backwash RO membrane filtration bottle, including bottle body 1, the bottle body 1 is equipped in filter flask shell 11, filter flask Shell 12 and filter flask head 2.The filter flask shell 11 is set in outside filter flask inner casing 12, the filter flask head 2 and filter flask shell 11 and filter flask The melting connection of inner casing 12 makes to form a gap 13 between filter flask shell 11 and filter flask inner casing 12.RO is equipped in the filter flask inner casing 12 Membrane filtration core 3,31 lower end of collector pipe of the RO membrane filtration core 3 pass through 12 bottom of filter flask inner casing and with 11 bottom phase of filter flask shell Meet place.The preferred forms of the utility model are: 11 bottom of filter flask shell is equipped with a setting circle slot 112, described to catchment Location and installation is carried out in 31 lower end of pipe insertion positioning circular groove 112.Guarantee that RO membrane filtration core 3 can be accurately positioned.

Specifically, 3 head of RO membrane filtration core is equipped with RO Membrane cover head 32, and described 32 one end of RO Membrane cover head is set in RO film On 3 head of filter body, the other end is inserted into filter flask head 2, and 31 upper end of collector pipe passes through RO Membrane cover head 32 and is inserted into filter flask head 2 It is interior.The preferred forms of the utility model: the RO Membrane cover head 32 is hollow structure.

More specifically, the filter flask head 2 is equipped with 3 connectors 21, and in the present embodiment, 3 connectors 21 are respectively Raw water mouth B, pure water mouth A and waste water mouth C.Cavity is equipped in the filter flask head 2, it is empty that the cavity is divided into the first cavity 22, second Chamber 23 and third cavity 24, the first cavity 22 are connected to pure water mouth A, and the second cavity 23 is connected to raw water mouth B, third cavity 24 with Waste water mouth C connection.In the present embodiment, the cavity is in pagoda shape structure.31 upper end of collector pipe is inserted into the first cavity 22 And it is connected in the first cavity 22.

More specifically, second cavity 23 is downwardly extending along side 231,322 one end of RO Membrane cover head insertion It is connected to along side 231 and in the second cavity 23.

More specifically, 11 bottom of filter flask shell is equipped with the supporting block 111 for several support filter flask inner casings 12.This In embodiment, it is provided with 4 pieces of supporting blocks 111 altogether, for reinforcing the connectivity between filter flask inner casing 12 and filter flask shell 11.

More specifically, 31 part of collector pipe in gap 13 is equipped with water outlet corresponding with 111 quantity of supporting block 311, the present embodiment is provided with altogether 4 water outlets 311.The water outlet 311 is corresponded with 111 position of supporting block.This reality The embodiment for applying example is: supporting block 111 being arranged on the center line of water outlet 311, water outlet 311 is divided into two, is had Conducive to the flowing of water.

The work step of the utility model is as follows:

Water process processed: as shown in Fig. 6,8, tap water touches inlet water solenoid valve and opens from PP cotton filter element to active carbon filter core, Electric-controlled plate controls booster pump operating, and certain waste water outflow is still maintained for after waste water solenoid closure and closure.Machine startup Water processed, raw water is after booster pump is pressurized, and the raw water mouth B water conservancy diversion through filter flask head enters RO Membrane cover head 32, and raw water is to RO membrane filtration core 3 Compression infiltration is carried out, pure water a part after permeation filtration comes out from 31 upper end of collector pipe outflow pure water mouth A water conservancy diversion, a part of pure Water flows in gap 13 from 4 water outlets 311 of 31 lower end of collector pipe.Waste water is from 3 tail end output of RO membrane filtration core and along RO It recalls between membrane filtration core 3 and filter flask inner casing 12 and is come out from filter flask head waste water mouth C water conservancy diversion.

Pure water compression process: as shown in Fig. 6,8, the tap that normally water process processed works as pure water mouth A connection is closed suddenly, is increased Press pump will be remained in operation a period of time due to inertia, and RO membrane filtration core 3, which continues infiltration, makes extra pure water from 31 lower end of collector pipe Water outlet 311 squeeze out, the air in pure water and compression clearance 13, waste water solenoid valve keeps certain stream still in closed state Speed.After high-voltage switch gear detects sufficiently large pressure, high-voltage switch gear instruction issuing electric-controlled plate, electric-controlled plate stops the information reception and registration pump housing It only runs, inlet water solenoid valve is closed.

Pure water backwash process: as shown in Figure 7,8, after the pump housing is out of service, with Wastewater by Electric before RO membrane filtration core film The bounce of air compression pure water is offset in the closure flow velocity pressure release of magnet valve until insufficient pressure, and air springs back pure water from collection at this time The water outlet 311 of 31 lower end of water pipe wall into RO membrane filter body is permeated and is backwashed RO film, synchronous dilution RO membrane filtration core 3 With the waste water between filter flask inner casing 12.

The foregoing is merely the preferred embodiments of the utility model, the utility model is not limited to above-mentioned embodiment party Formula, as long as realizing that the technical solution of the utility model belongs within scope of protection of the utility model with essentially identical means.
