Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of boilers, in particular to a smoke recovery mechanism and a boiler dust removal device. Background Art
[0002] Since the boiler dust removal device needs to discharge the smoke ash, the ash discharge pipe is usually designed to open downward, and an ash discharge plate is set on the ash discharge pipe as a control switch. Workers regularly pull out the ash discharge plate from the ash discharge pipe to discharge the smoke deposited on the ash discharge plate to the bucket car under the pipe mouth, thereby realizing the smoke recovery of the boiler.
[0003] However, traditional boiler dust removal devices rely too much on manual labor. Workers need to regularly pull out or insert the ash discharge plate, which results in high labor intensity for the workers. In addition, during the insertion process of the ash discharge plate, the ash discharge plate easily causes the accumulated ash to settle in the fixed groove of the ash discharge pipe, which is prone to blockage after long-term use, resulting in the ash discharge plate being unable to be smoothly inserted and fixed on the ash discharge pipe. Utility Model Content

The support tube is used to divide the movable channel into a first channel and a second channel, and the first channel is connected to the fixed hole.
[0018] By adopting the above technical solution, the ash discharge plate can be supported by arranging a support tube, thereby improving the structural strength of the ash discharge plate and helping to reduce the deformation of the ash discharge plate caused by excessive ash accumulation.
