The invention provides a chain grate machine operation chain structure. The chain grate machine operation chain structure comprises a plurality of small shafts and an operation support, the pluralityof small shafts are arranged on the operation support in parallel, each of the small shafts comprises a plurality of grate plates, a plurality of chain links, a plurality of chain link inner sleeves,a plurality of fixed-distance pipes, two side plates and two shaft sleeves, the grate plates are arranged side by side, the chain links are arranged among the grate plates, the chain link inner sleeves sleeve the chain links, and the fixed-distance pipes are arranged on the chain link inner sleeves; for each small shaft, the side plates are arranged on the side parts of the two grate plates at theend parts, and the grate plates at the end parts are connected with the operation support through the corresponding shaft sleeves; and each chain link comprises clamping spring grooves, the clampingspring grooves for each chain link are formed in the inner holes in the two sides of each chain link, each chain link inner sleeve comprises clamping springs, the clamping springs of each chain link inner sleeve are arranged at the two ends of each chain link inner sleeve, one ends of the clamping springs are fixedly connected with the chain link inner sleeves, and the other ends of the clamping springs are clamped in the clamping spring grooves. According to the chain grate machine operation chain structure, the problem that in the actual operation process of an existing operation chain, chain link inner sleeves move outwards can be thoroughly solved, so that the phenomenon that gaps between grate plates and chain links are increased due to the outward movement of the inner sleeves, and then material leakage of a grate bed can be prevented.
Description
technical field [0001] The invention relates to the field of chain grate equipment, in particular to a chain structure of a chain grate. Background technique [0002] The grate machine is the key equipment for pellet production, responsible for preheating, drying and roasting of raw pellets. The running chain consists of more than 500 small shafts, each shaft consists of 6 chain links, 6 chain link inner sleeves, 5 The spacer consists of two side plates and two small bushings. The running chain is subjected to temperature changes from room temperature to about 1100 degrees after one week of operation, so the requirements for the material of the running chain are very high. Due to the long-term operation of the running chain, the inner sleeve of the chain link connected between the chain links sprang out frequently, resulting in a gap between the grate plate and the chain link, the maximum gap was about 15mm, causing a large number of qualified balls to fall into the ash box...
