Specifically, be equipped with the clearance between the up end of baffle 13 and the internal face of cooling chamber 161, through the setting in clearance, further ensure the normal transportation of the material in transport assembly 1, avoid the material jam to lead to the unable normal transportation of whole transport assembly 1 on transport assembly 1.
Optionally, the size of the gap can be adjusted according to the particle size of the material actually transported, and the material transported in this embodiment is high-temperature fluidized material carried by powder and lump material, and the normal transportation of the material on the conveying assembly 1 can be ensured through the arrangement of the gap.
For example, the high-temperature material may be adhered in the conveying process in the conveying assembly 1, so that the size of the material is larger than the size of the sieve hole 232 of the sieve screen 231, when the size of the gap is smaller than 10mm, the material is very easy to contact with the inner wall surface of the cooling cavity 161, which affects the conveying efficiency, when the size of the gap is larger than 30mm, the excessive gap easily causes the space waste on the conveying assembly 1, and when the gap is too large, the cooling effect of the cooling piece 16 on the material on the conveying assembly 1 is reduced, which is not beneficial to the normal operation of the cooling piece 16.
In some embodiments, the transport length of the transport assembly 1 is less than or equal to 5 meters.
In particular, when the conveying length of the conveying assembly 1 is more than a meter, the conveying efficiency of the high-temperature fluidized material may be reduced, and the cooling effect of the cooling member 16 on the material may cause the temperature of the material after entering the side-blown converter 100 to be too low, thereby increasing the power consumption of the side-blown converter 100.
The feeding method of the side-blown converter provided by the embodiment of the invention comprises the following steps: when the materials need to be conveyed, the conveying member, the outlet and the adjusting member are opened, and the materials enter the conveying member from the outlet to be conveyed. The metering assembly meters the weight of the storage piece in real time and calculates the conveying amount of the conveying piece. The adjusting member and the power member are adjusted to adjust the conveying amount of the conveying member.
Specifically, the side blown converter is when carrying out the high temperature calcine feed, open and carry the piece, export and regulating part, the material gets into conveying assembly from the export of storage spare, in the inlet of the continuous motion transport side blown converter of conveying assembly, in the transportation process of material, the value that the measuring part reduces through measuring material weight in real time, calculate the feed quantity, smelt the condition according to the side blown converter, through the cooperation of regulating part and the power spare among the conveying assembly, the material feed quantity of side blown converter is adjusted.
