Detailed Description

As shown in fig. 1 to 3

The slag conveying device comprises a conveying pipeline 1, a chain transmission mechanism, two groups of lubricating assemblies and a plurality of scrapers 3.

Conveying pipeline 1 is square pipe, and conveying pipeline 1 lower extreme stretches into biomass gas stove bottom, and conveying pipeline 1 upper end stretches out the biomass gas stove outside, and conveying pipeline 1 upper end diapire and up end all open the row's of having slag hole 11 of discharge slag.

The chain transmission mechanism comprises a driving roller 21, a driven roller 22 and two chains 23, wherein the two chains 23 are tensioned outside the driving roller 21 and the driven roller 22, the driving roller 21 is driven by an external motor, a plurality of scraping plates 3 are sequentially welded on the two chains 23 at intervals, and the motion tracks of the end parts of the scraping plates 3 are in contact with the inner wall of the lower side of the conveying pipeline 1.
