Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example 1

Referring to fig. 1, 2 and 3, the RO membrane filter of the present invention includes a filter body, wherein a scale inhibition device 4 is detachably mounted on a water inlet side of the filter body; the scale inhibition device 4 comprises an annular box and a plurality of scale inhibition materials 45 arranged in the annular box, wherein a plurality of strip-shaped holes are formed in two annular flat end surfaces of the annular box, and the strip-shaped holes are communicated with the inner side and the outer side of the annular box; the strip-shaped hole 44 on one of the annular flat end surfaces of the annular box is used as a water outlet hole of the scale inhibition device 4 and is just opposite to the water inlet side of the filter body, and the strip-shaped hole 43 on the other annular flat end surface of the annular box is used as a water inlet hole.

In this embodiment, the scale inhibition device 4 is disposed on the water inlet side of the filter main body, so that the scale containing a large amount of calcium and magnesium components can be filtered, accumulation of large-particle scale on the RO membrane 3 is avoided, and normal use of the RO membrane 3 in the filter main body is ensured.

In this embodiment, for current high efficiency filter, need not the multilevel design, need not to design special adapter and pipeline, the user can dismouting by oneself to change corresponding part, this RO membrane filter has splendid filter effect, and does not receive geographical region restriction, hinders 4 convenient assembling of dirty device.

In this embodiment, ports B and C in fig. 1 are both water outlet sides, where port B is used for discharging wastewater, port C is used for discharging pure water, and port a is a water inlet side for introducing water to be filtered into the filter; the water to be filtered enters the annular box from the strip-shaped holes 43 of the scale inhibition device 4, large-particle calcium and magnesium component dirt is removed through the scale inhibition material 45, and then the water is discharged from the strip-shaped holes 44 of the scale inhibition device 4 and enters the RO membrane 3 for filtering; pure water obtained by filtration through the RO membrane 3 is discharged from the port C, and contaminated wastewater is discharged from the port B.

In this embodiment, because the strip-shaped holes at the two flat ends of the scale inhibition device 4 are designed with a plurality of holes, the phenomenon that the scale inhibition material 45 is accumulated inside can be prevented in the using process.

In the present embodiment, the specific components of the scale inhibiting material are not limited, and may be carbonate, etc., as long as it can remove scale forming ions such as calcium and magnesium.
