Abstract

The invention discloses an air leakage prevention device for sintering equipment, which relates to the technical field of sintering machine equipment improvement. The grate bar pressing pin includes a pressing pin head located on the inner side of the trolley fence, a circular truncated pressing pin rod that is fixedly connected with the pressing pin head and inserted into the pressing pin hole, and a pin pressing rod that is fixedly connected to the pressing pin rod. A reverse circular truncated cone arranged coaxially with the pressing pin rod, the taper of the reverse circular truncated cone is opposite to the inclination direction of the taper of the pressing pin rod, and the pressing pin hole includes a cylindrical inner cylindrical section matched with the reverse circular truncated cone, and the outer The diameter of the bottom surface is larger than the diameter of the bottom surface outside the press pin hole. The invention has the advantages of simple structure and convenient manufacture, avoids the phenomenon of air leakage caused by the inability of tightly combining the grate bar pressing pin of the sintering machine trolley with the trolley railing, improves the sintering output and the physical quality, and avoids the frequent falling off of the traditional grate bar pressing pin. question.

Description

technical field [0001] The invention relates to the technical field of sintering machine equipment improvement, in particular to an air leakage prevention device for sintering equipment. Background technique [0002] In the sintering production process, the air leakage of the sintering machine is very serious. According to statistics, the air leakage rate is generally above 50%. It can be seen from this data that more than half of the air volume drawn by the exhaust fan is not inhaled through the mixture layer, but It is wasted in vain. This air leakage phenomenon directly increases the energy consumption of the fan and a large amount of fuel consumption, and reduces the output of sinter. The output of sinter is proportional to the effective air volume passing through the bellows. At the same time, sintering air leakage increases the motor load of the main exhaust fan and increases the power consumption of sintering. The high air leakage rate restricts the improvement of th...
