Description

Super oxygen washing gravel unit

The invention mainly discloses a washing gravel unit, in particular to a super-oxygen washing gravel unit which uses super oxygen and shock to remove salts and harmful ions contained in the gravel.

Sand and gravel is an important substrate in engineering construction, mainly from riverbed and land. However, due to the current lack of production of river sandstone resources, the price is becoming more and more expensive, which often makes the major projects greatly Delay. The source of river sand is gradually deficient, and the mining of land sand will cause the damage of mountain landscape, the danger of earth and rock flow, the destruction of natural ecology, and the high cost of mining. Therefore, the development of diversified sources of sand and gravel has become an active issue. . Although the amount of imported sand and gravel has increased year by year, it has become the third source of domestic sandstone demand, but it is not a long-term solution. In view of the successful experience of countries such as Japan and the United Kingdom in developing and utilizing sea sand and the geographical environment of Taiwan, the sea sand shovel has become a potential source and may provide a source of fine wood for construction and construction in the future.

However, when the sea sand is actually used, the first problem encountered is the salt contained in the sea sand. The main components are KCL, MgCl ₂ , Na ₂ SO ₄ , CaCl ₂ and NaCl, among which chloride ion and sulfate are used. Ions are the most harmful to reinforced concrete. Chloride ion promotes the decomposition of bismuth salts in cement and accelerates the hydration reaction. In a relatively short period of time, a dense CSH colloid is formed, which constitutes a small amount of calcium vanadium and chloro- hydrate. Alumina has a high content, so that the concrete can obtain a higher early strength; however, it also destroys the pure protective film of the steel and causes corrosion of the steel. Another sulfate ion will react with the cement hydration product Ca(OH) ₂ to form CaSO ₄ . 2H ₂ O hydrate, which chemically reacts with C3A hydrate in cement to produce high calcium aluminate sulfate, also known as calcium vansparite, which causes volume expansion, cracking concrete, and affecting the durability of concrete. great.

Therefore, untreated sea sand contains salt, which can be directly used in concrete construction of civil engineering, construction, etc. as concrete aggregate without treatment, which may affect the durability of concrete structure and cause concrete expansion and crystallization. Poor sequelae such as flaking and corrosion of steel bars pose a potential hazard to building structures.

In order to eliminate the effects of salt in the sea sand, corrosion inhibitors such as Darex Corrosion Inhibitor (DCI) may be added to the concrete, or an anti-corrosive paint such as epoxy resin may be applied to the surface of the steel bar. ). However, the addition of corrosion inhibitors may have a negative impact on the volume of the concrete, while the anti-corrosion paint on the one hand only protects the steel bars and on the other hand does not meet the economic benefits. Therefore, the most fundamental method is to dilute the salt contained in the sea sand to meet the specifications.

At present, although domestic sea sand is not used in a large amount, a few unlawfully exploited beach sands and navigational sea sands have entered the market without proper salt washing, which may cause potential dangers to various construction and engineering quality, given the existing The problem and the potential for sea sand utilization in the future, it is necessary to develop an economical, fast and reliable method of salt washing, so that sea sand becomes a truly usable resource and is trusted by the public.

In the past sea sand desalination technology, there are generally sprinkling methods, dipping methods, natural placement methods, and mechanical desalination methods. Among them, the sprinkling method, the dipping method and the mechanical method are the most common, but among the above four methods, the common advantage of the first three is that the water consumption is small, and the salt content of the sea sand after the treatment is low, but the time required for the treatment is too Long, while the mechanical method requires less time to process, but it consumes more water. In view of the fact that the use of sea sand is very likely to be a future development trend, a rapid, economical and reliable sea sand desalination method is developed. For the current technology of development.
