Heat accumulating type heated brick bed capable of supplying hot air

Abstract

The invention discloses a heat accumulating type heated brick bed capable of supplying hot air, which comprises a heat source body, a pebble heat accumulating bed, heated brick bed plates and a chimney, wherein the heated brick bed plates are supported on the ground by heated brick bed plate pillars; a gap between the heated brick bed plates and the pebble heat accumulating bed is a heated brick bed body smoke and fire channel; the chimney is arranged to be perpendicular to the heated brick bed plates and communicated with the heated brick bed body smoke and fire channel; the heat source body comprises a biomass hot blast furnace and a heating pipe; the biomass hot blast furnace comprises a combustion chamber of which an outer end is opened, and a smoke and fire outlet which is arranged at an inner end of the biomass hot blast furnace; the smoke and fire outlet is communicated with the heated brick bed body smoke and fire channel; a dust accumulating pool is arranged below the smoke and fire outlet; the combustion chamber is provided with a furnace door; a lower side of the furnace door is arranged on a furnace door shaft; the furnace door shaft is fixed on a lower part of the combustion chamber; a fire grate is arranged below the combustion chamber; an ash falling box is arranged below the fire grate; an upside of the combustion chamber is fixedly connected with an air feeding chamber; an air pipe is fixed at an inner end of the air feeding chamber; an inlet of the air pipe is communicated with the air feeding chamber, and an outlet of the air pipe is communicated with an inlet of the heating pipe; the heating pipe is arranged in the heated brick bed body smoke and fire channel; an outlet of the heating pipe is connected with an air discharge pipe; and an outlet of the air discharge pipe is arranged out of the heated brick bed and is led to an indoor space.

Description

technical field [0001] The invention relates to the technical field of indoor heating facilities, in particular to a thermal storage kang for hot air. Background technique [0002] At present, the rural areas in the cold northern regions of my country still use traditional heated kangs, fire walls, stoves, and soil heating methods for heating. Among them, heated kangs are the most important heating method. There are many and scattered rural residents, and the heating area is large, so it is difficult to achieve centralized heating. At the same time, The heated kang can use any form of biomass fuel without increasing the economic burden on farmers. The traditional heated kang generally has the problems of large firewood consumption, waste of fuel, low indoor heat dissipation, low thermal efficiency, and poor indoor heating effect, and about 60-70% of the heat energy is wasted; the temperature of the kang surface is uneven, and heat storage The effect is poor, especially at ni...
