Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] combine Figure 4 As shown, the gap adjustment method of the running chain of the grate machine, including the adjustment steps of the connecting components;

[0022] Steps for adjusting the connecting components: after the small shaft 131 has been in operation for 150-210 days, set the clip backing plate 135 between the small shaft sleeve 132 and the positioning card 134 .

[0023] This gap adjustment method offsets the extension of the small shaft 131 by setting the clip backing plate 135 between the small shaft sleeve 132 and the positioning card 134, thereby avoiding the gap between the grate plates 120 on the running chain 100 and between the grate plates 120 and the chain links 111. increase. By controlling the running time to 150-210 days, it can be ensured that the length dimension of the small shaft 131 tends to be fixed, and basically does not extend...

Abstract

The invention belongs to the field of maintenance of pelletizing production equipment, and specifically discloses a method for adjusting the gap of the running chain of a grate machine, aiming to solve the increase in the gap between the grate plates on the running chain and between the grate plates and the chain nodes due to the extension of the small shaft. big question. The method for adjusting the clearance of the running chain of the grate machine comprises a connecting component adjusting step; the connecting component adjusting step: after the small shaft runs for 150 to 210 days, a clip backing plate is set between the small shaft sleeve and the positioning card. In this gap adjustment method, the small shaft is operated for a period of time, and after the length becomes fixed, a clamp backing plate is set between the small shaft sleeve and the positioning card to offset the extension of the small shaft, thereby avoiding the grate on the running chain. The gap between the grate plate and the chain link increases to prevent material leakage and prevent the running chain from running off.

Description

technical field [0001] The invention belongs to the field of maintenance of pellet production equipment, and in particular relates to a method for adjusting the clearance of the running chain of a grate machine. Background technique [0002] During the normal production process of the grate machine-rotary kiln pelletizing process, the operating chain of the grate machine will experience a harsh working environment from normal temperature to the temperature difference of 1100°C at the machine head. During this period, the operating chain of the grate machine will carry balls The lump ore is continuously transported to the rotary kiln. Such as figure 1 and figure 2 As shown, the chain grate operation chain 100 comprises a plurality of equal-length chains 110 of synchronous operation, a grate plate 120 arranged between two adjacent chains 110 by a spacer pipe, and a plurality of chains 110 and grate plates 120 are connected in connected components together. The chain 110 i...
