Two-stage screw feeding anti-tempering automatic slag removing burning device

Abstract

The invention discloses a two-stage screw feeding anti-tempering automatic slag removing burning device. The two-stage screw feeding anti-tempering automatic slag removing burning device aims at achieving the purposes that the tempering problem of a real flame fireplace can be effectively solved, and particle powder generated in the burning process can be effectively separated in time. The two-stage screw feeding anti-tempering automatic slag removing burning device comprises a workbin, a two-stage screw feeding device and a self-ash-slag-cleaning type burning device. The two-stage screw feeding device comprises an upper feeding barrel, an upper feeding barrel discharge port formed in the outer side face of the upper feeding barrel and provided with a downward opening, a lower feeding barrel located below the upper feeding barrel, a lower feeding auger rotationally arranged in the lower discharge barrel, a lower feeding barrel feed port formed in the outer side face of the lower feeding barrel and provided with an upward opening, and a discharging connecting pipe arranged on a discharge port of the output end of the lower feeding barrel and used for connecting the upper feeding barrel discharge port and the lower feeding barrel feed port, and a discharging port is connected with an upper feeding barrel feed port. The self-ash-slag-cleaning type burning device comprises a burning bowl with an upward opening.

Description

technical field [0001] The invention relates to a real fire fireplace, in particular to a two-stage spiral feeding anti-tempering automatic slag removal combustion device applied to a real fire fireplace. Background technique [0002] At present, real fire fireplaces are generally heated and ignited, that is, the biomass particles are heated by the heating rod, so that the fuel is smoldering to open burning (open flame); the biomass particles are usually fed by a feeding system. The feeding system of the current real fire fireplace is usually set above the furnace, which uses a funnel bin, and the lower part of the funnel bin communicates with the furnace through a feeding channel; when actually feeding, the biomass particles are poured into the funnel bin, Under the action of its own weight, the biomass particles gradually fall into the furnace along the feeding channel for combustion. [0003] At present, there are the following deficiencies in the real fire fireplace: Fi...

Problems solved by technology

[0003] At present, there are the following deficiencies in the real fire fireplace: First, during the combustion process of the furnace, the open flame in the furnace is easy to produce a backfire problem through the feeding channel during the continuous feeding process (the backfire problem refers to the open flame in the furnace passing through the feeding channel. extending into the silo, causing the biomass particles in the silo to catch fire); second, because the fuel particles do not move after falling into the combustion bowl, they have been burning in the combustion bowl, and the particle powder (ash) produced by combustion cannot If it is separated in time, the ash in the combustion bowl will be connected into blocks after a little longer time, which will affect the ventilation holes at the bottom of the combustion bowl, affect the combustion effect, cause stacking, the fuel cannot be burned smoothly, and affect the combustion quality of biomass particles.
