Description

Technical Field

[0001] The utility model relates to the technical field of basic magnesium carbonate, in particular to a feeding device for basic magnesium carbonate production. Background Art

[0002] Basic magnesium carbonate is an inorganic salt with the chemical formula Mg2(OH)2CO3, typically appearing as a white, loose powder or a brittle substance. It is nearly insoluble in water, but can cause light alkaline pulverization in water. Basic magnesium carbonate is insoluble in ethanol, but can be dissolved and foamed by dilute acids. Under normal circumstances, it does not decompose. Basic magnesium carbonate has a wide range of applications in the chemical industry. It is a highly stable compound that can be used to manufacture various materials such as ceramics, plastics, and glass. Its high dielectric properties and high ionic conductivity also make it important in the manufacture of electronic devices and batteries. In addition, basic magnesium carbonate plays an important role in the field of materials science and can be used to manufacture various composite materials and nanomaterials, which have applications in energy, environmental protection, medical care, aerospace, and other fields.

[0003] After the existing basic magnesium carbonate is carbonized, it enters a plate and frame filter press for extrusion and dehydration. After the water is removed, it is demolded from the plate and frame filter and directly sent to an oven for drying. However, since the shape and size of the magnesium carbonate filter cake are not easy to change, the work efficiency and the moisture content of the product drying are affected. If the filter cake is dried directly in the oven, it may not be thorough, resulting in the product not being able to be dried, which seriously affects the product yield and indicators, especially the moisture content. The moisture index of the magnesium carbonate after drying is uneven, which is directly related to the shape of the magnesium carbonate filter cake before drying. Therefore, a feeding device for basic magnesium carbonate production is proposed to solve the above problems. Utility Model Content
