Grid section pin for sintering pallet

Abstract

The invention relates to a pin, in particular to a grid section pin for a sintering machine trolley. The grid section pin comprises a cylindrical pin body and a square-block shaped briquetting which are connected into a whole, wherein the bottom surface, connected with the pin body, of the briquetting is square-shaped; a compressing pin body is arranged between the pin body and the briquetting; the compressing pin body is round-platform shaped. The grid section pin solves the difficult problem of air leakage caused by thermal expansion of the trolley, reduces energy consumption of an air blower and consumption of the fuel, and improves the productive output of agglomerate.

Description

technical field [0001] The invention relates to a pin, in particular to a grate pin for a sintering machine trolley. Background technique [0002] As far as the applicant knows, during 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%. From this data, it can be seen that more than half of the air volume drawn by the exhaust fan does not pass through the mixture. This kind of air leakage phenomenon directly causes the increase of fan energy consumption and a large amount of fuel consumption, and reduces the output of sinter; [0003] Through the long-term research and analysis of the sintering ventilation system, the applicant found that the sintering air leakage is mainly concentrated in the main part of the trolley; during the sintering process, due to the expansion of the trolley after being heated, the fit gap between the pin and the pin hole increases, and the g...
