Problems solved by technology

In the process of long-term use of the resin water filter device, scale is easy to accumulate inside the valve, which will reduce the flow rate or even block the valve, which will shorten the service life of the valve
Every time the valve is cleaned, it needs to be disassembled and reinstalled after cleaning. The operation is cumbersome and it is easy to cause the sealing performance of the valve connection to drop and leak.

Embodiment 1

[0061] A resin drainage apparatus, comprising a pre-processing means 6 in turn connected by a pipe 3, a reverse osmosis means, and the resin was filtered mechanism 2 4 post-processing means; a plurality of attached pipe 6 for controlling the on-off and / or the pipe 6 size of the flow valve 5; the resin was filtered mechanism 2 comprises a housing 21, provided in the cartridge housing in the anion resin and cation resin filter 21 22 23; 22 communicating with the female resin filter cartridge 23 of the male resin the anion resin filter element 22 and the male resin filter 23 are in communication with the conduit 6.

[0062] By the above-described embodiment, the present invention is to obtain at least the following technical effect: by controlling the valves 5, so that water flows from the pre-processing means 3, sequentially through the reverse osmosis means 1, filter means 2 the resin was treated to obtain purified water bodies 4. Purified water to achieve water softening effect ...

Embodiment 2

[0086] On the basis of the embodiment 1, the present invention also provides a method of flushing, the resin in the water treatment apparatus of the above-described embodiment, comprising the steps of:

[0087] S1: RO flushing mechanism 1;

[0088]The first solenoid valve 51, the second solenoid valve 52, the fifth solenoid valve 55, the second three-way valve 58 are turned off; the third solenoid valve 53, the fourth solenoid valve 54, the sixth soot electromagnetic valve 56 ;

[0089] The diaphragm pump 33 is activated, and the tap water is sequentially flowed through the PP / Scratchive activated carbon filter assembly 32, the first solenoid valve 51, the pressure reducing valve 34, and the diaphragm pump 33 flow into the reverse osmosis mechanism 1.

[0090] The flow of water filtered through reverse osmosis mechanism 1 is divided into two parts: concentrated water concentrated after filtration of reverse osmosis mechanism 1 is sequentially flowed through the regenerated water...

Abstract

The invention discloses a resin water filtering device and a flushing method. The resin water filtering device comprises a pretreatment mechanism, a reverse osmosis mechanism, a resin filtering mechanism and a post-treatment mechanism which are sequentially connected through pipelines, wherein a plurality of valves for controlling the on-off of the pipeline and / or the flow are mounted on the pipeline; the resin filtering mechanism comprises a shell, an anion resin filter element and a cation resin filter element, wherein the anion resin filter element and the cation resin filter element are arranged in the shell; the anion resin filter element is communicated with the cation resin filter element, and both the anion resin filter element and the cation resin filter element are communicated with a pipeline; the proportion of cation resin to anion resin in the resin filtering mechanism is adjusted, so that water flowing out is acidic or alkaline, and after the acidic and over-alkaline water enters the pipeline, the water scales in the pipeline and the valve are removed. On the premise that the valve is not disassembled, the valve is flushed through an acidic or alkaline solution generated by the resin water filtering device to remove scale, and a complex detachment step is avoided. Meanwhile, the problems that the sealing performance of the connecting end of the valve is reduced and the pipeline leaks due to frequent disassembly of the valve are avoided.

Description

Technical field [0001] The present invention is in the field of resin filter apparatus, and particularly to a method of rinsing the resin and the water treatment apparatus. Background technique [0002] Water treatment device is also called resin demineralizer, water softener, softener, softener equipment, water softener. Employing cation resin to soften water source to the cation resin adsorption of calcium and magnesium ions (the main component of the formation of scale), to reduce the source water hardness, may purifying water by-phase resin (cation and anion resin), and the resin may be regenerated, recycled. [0003] Resin water treatment apparatus is provided with many on-off valves and for controlling the flow velocity of the conduit. During long-term use in water treatment plant resin, easily accumulate inside the valve flow is reduced or even cause scale plug valves, it will shorten the life of the valve. Each need to disassemble the valve cleaning, reinstalled after cle...
