Description
[ field of technology ]
The invention relates to a manual regeneration soft cleaning integrated machine, and also relates to a soft water preparation method.
[ background Art ]
Tap water contains minerals such as calcium and magnesium, and under the conditions of heating or pressure mutation, calcium and magnesium precipitate in the form of carbonate to form common scale. The hardness of water is generally determined by the content of calcium and magnesium, the higher the content, the higher the hardness. Hard water causes great trouble to life, such as: 1, scaling wading devices, influencing the use or reducing the service life, such as water heaters, shower heads and the like; 2, calcium and magnesium in water and soap form water-insoluble calcium stearate and magnesium stearate, commonly known as scum, which are adhered to hair or skin to make the hair or skin rough and dry; 3, cleaning with hard water, more cleaning agent is required, and so on.
In order to solve the trouble caused by hard water, soft water is usually prepared by using a soft water machine, soft water substances capable of softening water quality, generally ion exchange resins, are arranged in the soft water machine, and calcium and magnesium minerals in water can be reduced or removed. When calcium and magnesium ions in the water pass through the resin, the calcium and magnesium ions are adsorbed by the resin, and sodium ions in the resin are released by replacement; when the resin is saturated in absorbing calcium and magnesium ions, the resin needs to be regenerated, and the resin is generally soaked in a high-concentration sodium solution or is soaked in a flowing mode, and the absorbed calcium and magnesium ions are replaced by sodium ions, so that the failed resin is recovered again.
The water softener sold in the market at present mainly comprises a softening water valve, a resin tank, a water distributor, a salt tank and other components, wherein the components are manually controlled and automatically controlled according to control types, and the components are a common water softener and a soft and clean integrated machine according to functions. However, such conventional water softeners are generally large in size and require a large installation space, and are an important cause for influencing popularization of water softeners for most domestic commercial residences.
There are also water softeners on the market for individual purposes such as showering, which are small in size, flexible in installation and very suitable for specific local space. Generally, most of such water softeners are not provided with a salt tank, and belong to manually regenerated water softeners, such as the water softener with the name of CN 206955709U.
However, the manual regeneration water softener with the salt-free box has more defects in the prior art:
1, no pretreatment function, and residual chlorine, colloid, sediment or rust in the water have great negative influence on the water production, regeneration, service life and the like of the resin;
2, the artificial soft water has no water hardness adjusting function, so that the water hardness is low easily, and the greasy feeling caused by difficult cleaning of the cleaning agent is generated, so that the use experience is greatly influenced;
3, no pollution discharge function is provided, for the salt-free tank water softener, the arrangement of a pollution discharge outlet can greatly improve the efficiency and effect of resin regeneration, namely, residual water in a resin draining tank is directly injected into salt solution for soaking and regeneration, such as an authorized bulletin number CN204281426U, which is named as a salt-free tank water softener, and the efficiency is extremely low due to self-dissolving, permeation and regeneration of solid salt;
4, the loosening-free stirring function, in particular to a water softener without raw water pretreatment, after long-term use, resin is easy to harden and pollute, so that the operation efficiency of equipment is low, even the service life of the resin is reduced, and the common treatment method is to introduce water flow along the reverse path of water making for backwashing, so that the hardening and pollution removal of the resin are relieved to a certain extent, but the common backwashing cannot effectively remove pollutants accumulated on the surface of the resin for a long time, thereby influencing the ion exchange efficiency of the resin and influencing the water making and regeneration effects;
5, bias current phenomenon is common, and the bias current phenomenon directly causes low resin utilization rate or resin hardening failure and the like; if the water softener is authorized to be provided with the bulletin No. CN204625389U, the water softener is named as a salt-free tank water softener with a back flushing function, and the back flushing effect is not ideal due to the bias flow phenomenon;
6, the manufacturing cost is high, which is also an important factor influencing the popularization of the small water softener;
and 7, taking over the vertical dispersion influence space in application, or taking over the mode is inconvenient for subsequent maintenance and disassembly, and the pipe and the machine are usually required to be disassembled simultaneously.
The present invention has been made based on the above-described situation.
