Correcting device for packing auger of spiral coal feeder

Abstract

The invention discloses a correcting device for a packing auger of a spiral coal feeder. The correcting device comprises a support, wherein the support is provided with a long-shaped hole; one end of the support is a fixed end; the other end of the support is a correcting end; the fixed end of the support is provided with a group of bearing seats; the correcting end is provided with at least two portal frames of a first portal frame and a second portal frame along a length direction in sequence; the first portal frame and the second portal frame are fixed on the ground and sheathed on the support; the bottom of the first portal frame is provided with a bottom lifting jack; an arc-shaped shaft seat of the bottom lifting jack penetrates from the long-shaped hole of the support; and the top of the arc-shaped shaft seat is provided with an arc-shaped shaft which can be used for being contacted with the bottom of a packing auger shaft of the packing auger of the spiral coal feeder; a top lifting jack is arranged between the top of the second portal frame and the packing auger shaft of the packing auger of the spiral coal feeder; and the arc-shaped shaft seat of the top lifting jack is provided with the arc-shaped shaft which can be used for being contacted with the top of the packing auger shaft of the packing auger of the spiral coal feeder. The correcting device is low in cost and short in period.

Description

technical field [0001] The invention relates to a correction device for a screw cage of a spiral coal feeder. Background technique [0002] The pulverized coal gasifier coal supply system is that after a certain amount of coal is stored in the coal storage tank, multiple spiral coal feeders send the coal into the gasifier by rotating the spiral blades. The spiral coal feeder is a cantilever-type screw mechanism, which is driven by a motor connection and transports the material to the gasifier through a heat-resistant and wear-resistant steel spiral piece. Steel), the length of the hollow shaft is about 3 meters, the diameter is about 120 mm, the height of the helical pieces on the twisted cage is about 60 mm, and the pitch gradually increases from 150 mm to 230 mm. Due to the large aspect ratio of this kind of twisted cage, it is easy to produce Flexible deformation, after deformation, friction and scratching will occur with the outer cylinder of the winch cage, which will ...

AI Technical Summary

Problems solved by technology

The spiral coal feeder is a cantilever-type screw mechanism, which is driven by a motor connection and transports the material to the gasifier through a heat-resistant and wear-resistant steel spiral piece. Steel), the length of the hollow shaft is about 3 meters, the diameter is about 120 mm, the height of the helical pieces on the twisted cage is about 60 mm, and the pitch gradually increases from 150 mm to 230 mm. Due to the large aspect ratio of this kind of twisted cage, it is easy to produce Flexible deformation, after deformation, friction and scratching will occur with the outer cylinder of the winch cage, which will shorten the service life of the winch cage and the outer cylinder, and increase the load on the motor, which will eventually cause the motor to trip, seriously affecting the normal production of the gasifier

In the past, after the twist cage of the spiral coal feeder was deformed, it was necessary to perform cutting corrections on a lathe over 5 meters high, and the correction cost was high and the cycle was long
