Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, and particularly relates to a solid particle and solution proportional mixing device for a mixer. Background Technique

[0002] During the long-term maintenance of blast furnaces and hot blast stoves, in addition to the daily inspection and maintenance of blast furnace equipment, more attention is paid to sealing the gaps between various refractories of the blast furnace body. Due to different physical factors such as the expansion coefficients of various refractories required for blast furnace masonry, during the production process, with the wear of refractories and the influence of other negative factors, such as water leakage, and the erosion and scouring of various gases, air leakage channels are formed, which affect the service life of the blast furnace. The external grouting method mainly solves the sealing of air leakage channels, thereby ensuring the service life of each refractory.

[0003] Due to different requirements for physical parameters in different parts of the blast furnace system, the selected grouting materials are also very different. The method of mixing and stirring solid particles with a solvent and then injecting is only one of them, which requires the use of a mixer.

[0004] Due to different mixing ratios of solid particles and solvents, the effects achieved for the problems to be treated are not satisfactory, resulting in relatively low construction efficiency, wasting manpower and material resources, and seriously affecting the normal production of blast furnaces in severe cases.

[0005] Based on this, a solid particle and solution proportional mixing device for a mixer is proposed. Content of the Utility Model
