Manual regeneration, softening and purifying all-in-one machine and water softening and producing method

Abstract

The invention discloses a manual regeneration, softening and purifying all-in-one machine which comprises a valve cover, the valve cover comprises a water softening cover and a water purifying cover which are of an integrated structure, a communicating pipe for communicating the water purifying cover with the water softening cover is arranged between the water purifying cover and the water softening cover, a raw water inlet is formed in the water purifying cover, a soft water outlet is formed in the water softening cover, the water purifying cover and the water softening cover are detachably connected with a water purification tank and a water softening tank with openings in the upper ends respectively, and a water purification filter element capable of purifying water flowing from the raw water inlet to the communicating pipe is arranged in a water purification inner cavity formed by the water purifying cover and the water purification tank; and a water softening assembly used for softening water flowing from the communicating pipe to the soft water outlet is arranged in a soft water inner cavity formed by the soft water cover and the soft water tank. The structure is compact, the size is small, and installation and application in special areas such as a shower cubicle are facilitated. The invention also discloses a method for preparing soft water, which comprises the following steps: firstly preparing purified water, then dividing the purified water into two paths, preparing soft water from one path of the purified water through resin, mixing the other path of the purified water with the soft water, adjusting the hardness and then outputting the soft water.

Description

【Technical field】 [0001] The invention relates to a manual regenerating softening and cleaning machine, and also relates to a soft water making method. 【Background technique】 [0002] Tap water contains minerals such as calcium and magnesium. Under conditions such as sudden changes in heating or pressure, calcium and magnesium precipitate in the form of carbonate, forming commonly known as scale. Generally, the hardness of water is determined by the content of calcium and magnesium. The higher the content, the higher the hardness. Hard water causes great troubles to life, such as: 1. Scaling of wading equipment, affecting use or reducing service life, such as water heaters, showers, etc.; 2. Calcium and magnesium in water and soap form water-insoluble stearic acid Calcium and magnesium stearate, commonly known as scum, adhere to the hair or skin and make it rough and dry; 3. Cleaning with hard water requires more detergent and so on. [0003] In order to solve the problems...

AI Technical Summary

Problems solved by technology

[0007] 1. Without pretreatment function, the residual chlorine, colloid, sediment or rust in the water will have a great negative impact on the water production, regeneration and service life of the resin;

[0008] 2. There is no water hardness adjustment function. Artificial soft water can easily cause the water hardness to be too low, resulting in a greasy feeling caused by cleaning agents that are difficult to clean, which greatly affects the user experience;

[0009] 3. There is no sewage discharge function. For water softeners without salt tanks, the setting of the sewage outlet can greatly improve the efficiency and effect of resin regeneration, that is, drain the remaining water in the resin tank and directly inject salt solution for regeneration, such as authorized announcement number CN 204281426 U, the name is a salt-free tank water softener, which is regenerated by solid salt self-melting and osmosis, and the efficiency is extremely low;

[0010] 4. There is no loosening and stirring function, especially for water softeners without raw water pretreatment. After long-term use, the resin is easy to harden and easily polluted, resulting in low equipment operation efficiency and even reducing the service life of the resin. The usual treatment method is along the water production line. The reverse path leads to water flow for backwashing. Although the hardening and decontamination of the resin are relieved to a certain extent, this kind of ordinary backwashing cannot effectively remove the pollutants accumulated on the surface of the resin for a long time, which affects the ion exchange of the resin. Efficiency, which affects water production and regeneration;

[0011] 5. The phenomenon of partial flow is common, which directly leads to the low utilization rate of resin, or the failure of resin hardening; for example, the authorized announcement number CN 204625389 U, the name is a kind of water softener without salt tank with backwash function, and the backwash is also caused by the partial flow phenomenon The effect is not ideal;

[0012] 6. The manufacturing cost is high, which is also an important factor affecting the popularization of such small water softeners;

[0013] 7. During application, the upper and lower scatter of the connecting pipe affects the space, or the connecting method is not convenient for subsequent maintenance and disassembly, and usually needs to be disassembled at the same time for the pipe and machine
