Description

Method for producing water mineralizing ball with Chinese medical stone

The present invention relates to a method for making mineralized balls by using Chinese medical stone as basic raw material and applying physical and chemical condition change to it.

A large number of tests and analyses prove that the medical stone contains all trace elements required by a human body. Therefore, it has the functions of regulating metabolism, promoting blood circulation and participating biochemical reaction of human body, and has special health-care and therapeutic effects on human body, especially people with sub-health constitution. The active trace elements in Maifanitum are obtained by soaking in water. The process is to soak the medical stone blocks in water, wherein trace elements can be slowly dissolved out when the water can contact the surface of minerals, exist in the water in an ionic state, and are utilized byhuman beings after drinking.

Maifanitum silicate rock with density of 2.67g/cm³It is relatively dense, and many trace elements inside it are present in mineral lattices, and are difficult to dissolve in an aqueous solution. The crystal lattice has better dissolution effect only after being loosened by natural weathering and damaged. Maifanitum weathered in nature is only present on the surface layer of rock mass. Due to rainfall erosion, part of trace elements in the medical stone weathered layer are lost along with rainwater, and the application value of the medical stone is greatly reduced.

The trace elements in the weathered medical stone can be dissolved out as a result of a series of physicochemical evolution.

Physical conditions of natural weathering

The rocks and minerals formed in the deep part of the earth become unstable after entering the earth surface, and the rocks are continuously broken and crushed after being exposed to the sun, blown by the wind, drenched by the rain and washed by river water, and the grains are gradually thinned and are more easily weathered. Medical stone is a rock, although no exception exists. The test result shows that the elution amount of the trace elements in the medical stone is in a direct proportion relation with the specific surface area of the medical stone, and the test result of the specific surface area shows that the specific surface area is increased and the eluted trace elements are increased along with the thinning of the granularity. In addition, the mineral structure of the medical stone is closely related to the specific surface area. Fresh medical stone is compact, the specific surface area of the fresh medical stone is small, and the specific surface area of the fresh medical stone is greatly increased after weathering. The specific surface area of the medical stone is increased because some minerals form cavitiesafter weathering, the surface of the feldspar is generally loose and porous after weathering, a coral-shaped structure is formed in some feldspar, and wide holes and large channels are formed in some feldspar, so that the specific surface area of the medical stone is increased.

Chemical conditions of natural weathering

1. Carrying out hydrolysis reaction; hydrolysis takes the first place in various chemical reactions at the surface. Ionization of hydrolyzed to water to produce H⁺、OH^-Exchange reaction with mineral ions. Hydrolysis of feldspar in silicate minerals is exemplified:

in the reaction H⁺The ion plays a decisive role in converting the metal (K)⁺、Na⁺、Ca²⁺Etc.) to expel the aluminosilicate, thereby destroying the mineral's lattice structure.

2. Oxidation reaction and reduction reaction: the surface oxidation reaction mainly takes place in an aqueous medium in which free oxygen is dissolved, and is an important process leading to the decomposition of low-valent iron-containing silicates. When containing iron (Fe)²⁺) When the silicate oxidizes, hydrated decomposition products of the ferric iron will eventually be formed.

Because the oxidation energy of iron is quite large, it is very sensitive to the oxidation process. The structure of the silicate mineral collapses as the iron bound to the silicon tetrahedra in the silicate lattice combines with the oxygen to form an oxide.

3. Hydration: hydration refers to the process of incorporating water molecules into the mineral lattice. The hydration process often increases the volume of the material, thereby spoiling the structure of the mineral.

4. Carbonation: carbonic acid (CO)₃)^2-And heavy carbonic acid (HCO)₃)^-The interaction of the molecules with minerals and rocks causes carbonation. As a result of which the mineral is partially or completely dissolved and the metals contained therein are converted into carbonates. The carbonic acid can dissolve divalent metal (Ca)²⁺、Mg²⁺、Fe²⁺) Carbonate of (2)

Hydrolysis of silicates is often accompanied by the action of carbonic acid.

As can be seen from the chemical reaction characteristics of the above example, the general trend of surface weathering is towards oxidation, carbonation and water enrichment, and the volume of rocks and minerals is increased and the specific gravity is reduced due to the addition of fluid phase components, so that the anhydrous complex silicate minerals formed in a high-temperature environment are changed into simple compounds rich in volatile components.

In conclusion, the fresh medical stone can only play a role after weathering, so that the trace elements in the medical stone are dissolved out in water. However, the existing medical stone utilized by people is processed into particles after being crushed, so that fresh surfaces appear, and trace elements in the medical stone are not favorably separated out in water or the separation amount is extremely low.

The invention aims to provide a method for producing medical stone mineralized spheres, wherein naturalweathering conditions are simulated in the method, so that fresh medical stone is fully weathered in the method, and the precipitation amount of beneficial trace elements in the medical stone mineralized spheres is increased.

The purpose of the invention is realized according to the following process flow:

1. crushing: crushing equipment is used to process massive maifanite into fine particles, the diameter of which is generally 150 meshes (0.10 multiplied by 10)^-3m) -200 mesh (0.07X 10)^-3m). The efflorescence effect is influenced by the too fine and too coarse particle size of the crushed particles.

2. Adding a binder; 5% of clay is added into the medical stone particles, so that the loose medical stone particles are easy to be cemented. The clay mineral has a granularity similar to that of the medical stone, and is fully mixed to be as uniform as possible.

3. Pelletizing: the medical stone particles are put into a ball making machine and are processed and formed by adding water. Sufficient moisture is obtained between the medical stone particles to prepare sufficient hydrolytic fluid for the next weathering.

4. Polishing: and polishing the medical stone mineralized balls by using a rolling polisher. The purpose of polishing is not only to make the surface of the medical stone mineralized ball smooth and beautiful, but also to perfect a closed system required by the weathering of the medical stone mineralized ball.

5. Drying: the medical stone mineralized spheres are sent into a drying chamber for drying, the temperature is gradually increased to be not more than 100 ℃, and hydrolysis and hydration are started to be carried out in the medical stone mineralized spheres in the drying process.

6. And (3) calcining: the dried medical stone mineralized ballsare put into a return air kiln to be calcined. The temperature is controlled to be about 500-650 ℃, the temperature is too high, and silicic acid minerals are easy to vitrify to influence the dissolution of trace elements in the silicic acid minerals. Through calcination, a small amount of As, Hg, Pb, Sb, Cd and other harmful elements contained in the medical stone are decomposed or oxidized in the high-temperature process, become gaseous and are volatilized and removed, so that the content of the harmful elements is reduced or eliminated. Meanwhile, the beneficial elements can be increased. Because the weathering chemical reaction is accelerated by the increasing temperature.

All of the above works were performed in a sterile environment.A comparison table of trace elements dissolved out from fresh medical stone particles and medical stone water quality mineralization balls is given below: elemental medical stone particle medical stone mineralized spheres Ca 400017500 Mg 5005880H₂SiO₃1200 78620Na 3000 17850K 400 14220P 30 320Sr 15 80Mn 26 51Zn 12 26Cu 2.5 7.6Se 0.13 9.5F 12 320Mo 3 3.7

As can be seen from the above table, the amount of dissolved trace elements of the medical stone mineralized spheres produced by the invention is greatly higher than that of the existing medical stone particles.

The invention is further illustrated by the following example.

1. Crushing: processing the large medical stone into fine particles with the diameter of 150 meshes (0.10 multiplied by 10) by adopting crushing equipment^-3m)。

2. Adding a binder; adding 5% of clay into the medical stone particles: kaolinite makes loose Chinese medical stone particles easy to be cemented. The clay mineral has a granularity similar to that of the medical stone, and is fully mixed to be as uniform as possible.

3. Pelletizing: the medical stone particles are put into a ball making machine for processing and forming. Water must be added during the batting process to ensure that the medical stone particles obtain sufficient water, and a sufficient hydrolytic fluid phase is prepared for the next weathering action.

5. Drying: the medical stone mineralized spheres are sent into a drying chamber for drying, the temperature is gradually increased to 80 ℃, and the interior of the medical stone mineralized spheres starts to be hydrolyzed and hydrated in the drying process.
