Double-grate spindle respective adjusting device on large-capacity corner tube boiler

Abstract

The invention discloses a double-grate spindle respective adjusting device on a large-capacity corner tube boiler, which aims at solving the problems of grate bulging and chain tightness adjusting and comprises a left end adjusting bolt assembly, a chain wheel assembly, a spindle assembly, scale-type grate bars, a right end adjusting bolt assembly, a right side grate spindle assembly and a left side grate spindle assembly, wherein the chain wheel assembly is arranged on the spindle assembly, the scale-type grate bars are arranged on the chain wheel assembly, the left end adjusting bolt assembly is arranged on the left side grate spindle assembly, and the right end adjusting bolt assembly is arranged on the right side grate spindle assembly. The double-grate spindle respective adjusting device on the large-capacity corner tube boiler has the advantages that adjusting bolts are vertically arranged and respectively independently control a left side grate and a right side grate, so that the left side grate and the right side grate are not affected with each other during adjusting, labor intensity of operators is reduced, and the double-grate spindle respective adjusting device is convenient to operate and can be widely applied to the large-capacity corner tube boiler to serve as a spindle adjusting device.

Description

technical field [0001] The invention relates to a device for adjusting a main shaft of a fire grate, in particular to a device for separately adjusting the main shafts of a double fire grate on a corner tube boiler. Background technique [0002] The dual-grate spindle adjusting device is mainly used for adjusting the grate on the large-capacity corner tube boiler. Because the large-capacity corner tube boiler scale-type double furnace is a type of furnace that users love, it is used in a large amount. However, due to the structural design of the grate, when the user finds that the grate is arched and the chain is too loose, it needs to be adjusted. , it is generally solved by adjusting the spindle, such as figure 1 As shown, this adjustment uses the middle adjustment bolt on the main shaft (called three-point adjustment). When the operator does not operate properly, the tightness of the grate chain on one side will affect the tightness of the grate chain on the other side, ...

AI Technical Summary

Problems solved by technology

Because the large-capacity angle tube boiler scale type double furnace is a type of furnace that users love, it is used in a large amount. However, due to the design of the grate structure, when the user finds that the grate is arched and the chain is too loose, it needs to be adjusted. , it is generally solved by adjusting the spindle, such as figure 1 As shown, this kind of adjustment uses the middle adjusting bolt on the main shaft (called three-point adjustment). When the operator does not operate properly, the tightness of the grate chain on one side will affect the tightness of the grate chain on the other side, so the adjustment is neither It is convenient, time-consuming, and labor-intensive for operators. Due to the structural design of the grate, this problem has not been solved so far and needs to be studied by people.
