Packaging structure of fire-resistant materials in bulk and packaging method of fire-resistant materials in bulk

Abstract

The invention discloses a packaging structure of fire-resistant materials in bulk which comprises ton bags and materials in bulk hermetically filled into the ton bag; 0mm to 1mm of grain materials, fine powder, micro powder and various additives in the materials in bulk are uniformly mixed in mixing equipment into premixing powder at the bottom of the ton bag; and each 1mm of component in the materials in bulk is put on the premixing powder according to the grain level from small to large in sequence. The invention further provides a packaging method of the fire-resistant materials in bulk which comprises the following steps of: 1, uniformly mixing the 0mm to 1mm of grain materials, fine powder, micro powder and various additives in the materials in bulk to prepare premixing powder and load at the bottom of the ton bags; 2, putting each 1mm of component on the premixing powder; and 3, sealing the ton bags. The packaging structure of the fire-resistant materials in bulk and the packaging method of the fire-resistant materials in bulk, disclosed by the invention, have the advantages that: the cost is saved; and the materials in bulk are ensured with stable construction performance and longer storage time.

Description

Technical field [0001] The invention belongs to the production field of unshaped refractory materials, and specifically relates to a packaging structure and a packaging method for refractory bulk materials. Background technique [0002] Unshaped refractories have the advantages of energy saving, environmental protection, simple construction, convenient maintenance, etc., so the proportion of refractories used in high-temperature industries such as metallurgy, petrochemical, cement, and glass is increasing. Unshaped refractories contain particles, fine powders and micropowders with different particle size gradations. In addition, there are traces of additives that are essential to their construction performance. Generally, fine powder, micropowder and admixtures are pre-mixed during production, and then mixed with large-grain aggregates, and finally sealed and packaged. During on-site construction, it is necessary to add water or other liquids while stirring in the mixing equipme...

AI Technical Summary

Problems solved by technology

[0003] The current production method of refractory bulk materials has the following problems: (1) Most of the large particle raw materials contain large pores, such as fused corundum, fused magnesia and various lightweight aggregates, etc., which are mixed with premixed powder When uniform, fine powder, micro powder and admixture are easily filled into these pores

During on-site construction, these powders are difficult to contact with external moisture or other liquids, resulting in deterioration of the construction performance of bulk materials

(2) Manufacturers generally purchase lump ore raw materials and crush them into aggregates by themselves. These lump ores are generally stacked in the open air and inevitably contain moisture. Therefore, after mixing large particle aggregates with premixed powder and packaging them together, the time will increase. React with the additives, cement, silica powder, gel powder, etc. in the premixed powder to form agglomerates, resulting in greatly shortened storage time

(3) The mixing process of general refractory bulk materials during on-site construction is sufficient to mix the aggregate and premixed powder, so the mixing process during production is somewhat redundant
