Hard water softener

Abstract

The invention relates to a hard water softener, which consists of a 12V direct current power supply, a multivibrator, a square-wave oscillator, an alternating electromagnetic field forming circuit and a work state indicating circuit. Double time-base circuits IC1 in the multivibrator and the square-wave oscillator adopt model NE556. When the hardness of water is greater than 450mg / l, if softening treatment is not preformed, industrial production and daily life of people will be directly influenced. Hard water will influence results of chemical tests and product quality in industry. In domestic life, repeated drinking of the water in such a container will influence on the health of people. In order to solve the problem of softening hard water, an alternating electromagnetic field is generated electronically, that is to say, applying an appropriate electromagnetic field to hard water at the inlet of a water supply system for recombining or interfering or changing original characteristics of the vast majority of calcium magnesium carbonate, calcium magnesium carbonate and mercury, cadmium, lead and arsenic ions in water so as to soften the hard water. Water softening in an electrical manner much lower cost than the cost of water softening in a chemical manner and is environment-friendly and free from any pollution.

Description

technical field [0001] The invention belongs to the technical fields of electronic technology and water treatment, and relates to a hard water softening device. Background technique [0002] The hardness of water depends on the content of calcium, magnesium, iron, aluminum, manganese carbonate, sulfate and other salts in the water. The unit of water hardness is to convert all the salts in the water into calcium carbonate. When the calcium carbonate in water is less than 150 mg / L, it is called soft water; when it is 150-450 mg / L, it is called hard water; 450-714 When it is more than 714 mg / L, it is high hard water; when it is greater than 714 mg / L, it is extra hard water. [0003] When the hardness of water is greater than the hygienic standard of 450 mg / L, if the softening treatment is not carried out in time, it will directly affect industrial production and people's daily life. In industry, hard water will affect the results of chemical tests and the quality of products ...

AI Technical Summary

Problems solved by technology

In industry, hard water will affect the results of chemical tests and the quality of products in industries such as papermaking, pharmaceuticals, electronics, chemicals, food and beverages, and even lead to serious consequences; in life, the hardness of water is too high. Soap does not foam and causes waste; washing clothes with hard water can easily make the textile fibers hard and brittle and damaged; bathing with hard water and washing hair can feel astringent and sticky; the hardness of water is too high, and it is easy to get stuck in the container. Scale is formed, once the scale is formed, it will waste more than 1 / 3 of the fuel for boiling water
